Falling from high altitude has been a focus of attention in the industry, the people and the public in recent years, and the social response is strong. From January 25 to 30, 2007, at the Fifth Session of the Tenth Beijing CPPCC, Li Qingyan, a member of the CPPCC, put forward &”;Suggestions on falling objects from high altitude&”; and was included in &”;Proposal No.0716 of the Fifth Session of the Tenth Beijing CPPCC&”;. After the meeting, seven relevant departments, including the Municipal Radio and Television Bureau, the Municipal Education Commission, the Municipal Administration Committee, the Municipal Bureau of Land and Resources, the Municipal Construction Committee, the Municipal Planning Commission, and the Office of Spiritual Civilization of the Capital, made a report on the &”;Proposal 0716&”;. This is the first time that local governments in China have thought and expressed their views on the legislation of &”;high-altitude parabolic accident&”;, which is of great significance. The background information of &”;Proposal No.0716&”; is my &”;proposal on legislation of falling objects from high altitude&”; for Jiu San Society. On September 13th, 2007, we rec—— Bai Baokun, executive director of Building Decoration Association and general manager of Dongguan Jianlang Hardware Products Co., Ltd., &”;A woman was injured when a glass fell from the sky in Shenzhen, and a falling object sounded the alarm again&”;, and please forward it to President Ma Tinggui, Executive Vice President Xu Peng and other leaders of the association. &”;Parabolic accident at high altitude&”; has once again attracted the attention of industry leaders. First, falling objects ring the alarm bell again &”;high-altitude parabolic accident&”; provided by Bai Baokun —— ——2007 reported on September 10, 2007: falling objects ring the alarm bell again! At 4 o&;clock in the afternoon yesterday, two pieces of glass suddenly fell on the third floor of the complex building of Liyuan Community, Xuefu West Road, Nanshan District, Shenzhen, and smashed into the neck of a passing woman. The woman was bleeding profusely at that time and was rushed to Nanshan Hospital for rescue. She is now out of danger. Scene: When the injured person was smashed, he was holding a child at 7 o&;clock on the evening of the 9th. When the reporter rushed to the scene, there was a large pool of blood at the incident site. Two pieces of glass were missing from the window on the third floor, and the glass baffle of the shop on the first floor had been smashed. There were some glass fragments on the ground. The police line has been set up at the scene, and the police are investigating the incident. There are nearly 100 onlookers. A witness at the scene recalled to the reporter an amazing scene at that time: &”;I passed by here at that time and only heard a bang. I turned around and saw that a woman had fallen in a pool of blood! The two children with the injured next to them are crying! &”; Another witness said that at that time, two pieces of glass fell from the third floor, first hitting the baffle of the shop on the first floor, and then hitting the neck of a woman passing by. At that time, the woman was holding a two-year-old child and pulling a five-year-old child. Fortunately, the two children were not hurt, but kept crying beside their mother. &”;If the glass didn&;t hit the first floor and hit the woman directly, the consequences would be unimaginable.&”; About two minutes after the incident, an enthusiastic citizen dialed 120, but when the ambulance arrived at Xuefu West Road, there was a traffic jam. A security guard in the community saw that the situation was urgent and the injured person was dying. In desperation, he quickly picked up the injured person and stopped a taxi, but the driver refused to cooperate, and then stopped a policeman patrolling here.Motorcycle, rushed to the nearby Nanshan Hospital for emergency treatment. Citizen: The window safety inspection of renters should be strengthened at 8 o&;clock on the evening of the 9 th. When the reporter rushed to Nanshan District Hospital, the doctor told the reporter that the injured person was out of danger, but he was seriously injured and needed hospitalization for some time. At about 9 o&;clock, the reporter returned to the scene of the incident, and many citizens in the community still talked about this incident. According to a citizen&;s report to reporters, the third floor has been rented to an education company recently, and it works until 12 o&;clock every day, which is very noisy and makes residents restless. Since this is a renter, the glass has never been maintained. The cause of this accident is probably that the loose glass fell when the employees of this company closed the window. To this end, some citizens called on the residential management office to strengthen the management of residential tenants to avoid similar incidents from happening again. At present, the police are investigating the cause of the accident. Second, the classification of falling objects accidents in recent years, such incidents have risen and fallen all over the country. From the perspective of buildings and falling objects, there are the following five categories: (1) The glass of public buildings fell into Shenzhen and fell from the sky, killing primary school students. According to 《深圳晚报》, on the evening of May 31, 2006, a piece of flat glass with a thickness of 10mm and the size of a tabloid suddenly fell over the sidewalk on the south side of Hyde Second Road, killing and injuring two fourth-grade pupils who were walking home. According to the people nearby, just five hours before the accident, there was a piece of 9mm thick glass, which fell over the sidewalk on the north side of the road and smashed. Because no one was harmed at that time, it did not arouse people&;s due vigilance, find out the reasons in time, and prevent problems before they happen. Last night, a reader called the newspaper&;s news hotline to report that at 17: 55 that night, he passed by Hyde Second Road and happened to encounter a flat glass falling from the sky, hitting two primary school students who came home from school. The police arrived and were rescuing people. The incident was located on the sidewalk on the south side of Haide Second Road in Nanshan District, about 10 meters away from the 20-storey Haolaiju residential building next to it. When the reporter received the report and rushed to the scene, Nanshan police had set up a cordon at the scene. Many pedestrians stopped to watch and felt sorry. There is a pool of blood and a small skull of seriously injured pupils on the road; Next to him stood his umbrella, lunch box and an empty bottle of mineral water. Within about 30 square meters around the pool of blood, there are many pieces of glass scattered, some of which are stained with blood. The people at the scene told the reporter that the two injured primary school students were all students in Class 4, Grade 4, a nearby primary school. They were traveling westbound along the sidewalk at the time of the incident, but unfortunately they encountered an accident. Nanshan police arrived in time, transferred the injured to the hospital for treatment, and launched an investigation into the cause of the accident. At 7 o&;clock that night, the reporter found Xiao Huang, a student who was slightly injured in the accident in a nearby primary school. He recalled that the glass falling from the sky hit the classmate who walked side by side with him. When the classmate fell to the ground, the broken glass scratched Xiao Huang&;s legs and clothes, causing minor injuries. At 8 o&;clock that night, the reporter learned from the hospital that Xiao Huang&;s classmate had died because of his injuries. During the interview, witnesses said that the accident was suspected to be caused by malicious throwing objects at high altitude.Many people reported that just five hours before the accident, a piece of glass across the road from the scene of the accident fell from the sky and was scattered on the road about 20 square meters north of Hyde Second Road. Fortunately, no one was hit. Regrettably, at that time, it did not arouse everyone&;s due vigilance and failed to find out the truth in time to prevent problems before they happen. As of press time at 9 o&;clock last night, the police said that the cause of the incident was still under investigation. In addition, according to th《深圳特区报》 in 2006 on the death of passing pupils by falling glass blocks from high buildings, since this newspaper reported that Xiaoyu, a fourth-grade student of Nannan Primary School in Nanshan District, was killed by falling glass, it has aroused strong social repercussions. In recent years, falling objects from high altitude have become a great harm to the life of urban residents, and the tragedy of falling objects injuring people has occurred from time to time in our city. The blade glass from the sky cut two passers-by. According to th《文汇报》 on December 5th, 2006, there were two cases of injuries caused by falling objects in North Point and Kwun Tong yesterday. A passer-by and a secondary five boy were injured by falling blades and glass fragments respectively, but fortunately, the injuries were not serious. Among them, police officers arrested a 94-year-old woman in one unit of a building in Cuiping, Kwun Tong for investigation. I believe that it was an accident that the strong wind blew the glass window into the buried wall; As for the scene where the blade fell in North Point, no one was arrested for the time being. At 12: 42 yesterday afternoon, a 47-year-old passerby, Li Xhui, passed by Oil Street in North Point near King&;s Road, and suddenly felt bleeding on his head. He found that a blade about 1 inch by 2.5 inches rebounded and fell to the ground. He believed that it was hit by a blade falling from the ground upstairs, so he called the police for help. At 1: 38 pm yesterday, He Xqin (16 years old), a middle school student, was walking alone through the shopping platform on the second floor of Cuizi Building in Cuiping after lunch, when he was suddenly cut by a piece of glass falling from a height, he was sent to hospital by passers-by. Two people were injured when an aluminum alloy window fell in Xiamen. According to S《海峡都市报》 Supermarket opened, and a celebration performance was held in the evening to attract passers-by. However, this incident is a mixed blessing for motorcyclists Zuo and Guo: I am very happy to watch the performance, and the window falling from the sky is on my head, and my luck is bad enough. At 11 o&;clock on the evening of September 2, police officer Zhang of the pontoon police station handled the case of falling objects and wounding people. Police officer Zhang told reporters that the incident happened in a supermarket in Qishan Industrial Zone, Licheng. At that time, the supermarket had just finished outdoor celebrations to celebrate its opening. After the activity, something happened: an aluminum window fell from the building and hit Zuo and Guo in the head. When police officer Zhang rushed to the scene, he found that the safety helmet worn by Zuo was torn apart, leaving only a brim, head, shoulders and other injuries; Guo&;s helmet is intact, and only his leg is scratched by glass. Afterwards, with the help of the window owner, two motorcycle workers were sent to Wanxiang Minimally Invasive Hospital for treatment. It is understood that Guo&;s helmet cost more than 30 yuan, while Zuo bought it from a roadside stall at the price of 10 yuan. Police officer Zhang reminded that the result of this accident is more or less related to the safety performance of the helmet. It is best for motorcyclists to buy helmets at regular stores. The decorator smashed the glass two ways.Hand injury. According to th《明報》 on September 22nd, 2007, there was an incident of falling objects in Guilin Street yesterday afternoon. Two female passers-by were suddenly cut on their foreheads and hands by the &”;glass rain&”; falling from the sky when passing across the subway station, and needed to be sent to hospital for treatment. After investigation, the police arrested a decoration worker on the rooftop of a nearby building, believing that he accidentally broke the glass during the decoration and caused an accident. Two female passers-by who were cut by the &”;glass rain&”; were Huang Xzhen, aged 36, and Zhou Xhao, aged 47. They were slightly injured in the forehead and hands, and were sent to Caritas Medical Center for treatment after being bandaged. After investigation by the police, Zeng X-xing, a 49-year-old decorator, was arrested in a terrace on the 12th floor of Yucheng Building, No.143 Guilin Street. According to the on-site news, the accident unit belongs to a man surnamed Zheng, and renovation works are being started recently. At 4: 27 p.m. yesterday, after installing an air conditioner in the street-facing window at the site, Zeng tried to install a piece of glass about 1.5 feet by 1 foot next to the window frame, and accidentally broke the glass, and some fragments splashed and fell, hitting Huang and Zhou, who were passing through the exit of Guilin Street subway station. Beijing High-altitude Glass Injury School awarded 20,000 yuan. Mr. Meng was injured by falling glass when he asked for directions at the north gate of Beijing Institute of Technology. On S《新京报》 reported that the Haidian Court had awarded Beijing Institute of Technology more than 20,000 yuan in compensation. On November 5, 2006, when Mr. Meng asked the security guard for directions at the north gate of Beijing Institute of Technology, a piece of glass of unknown origin fell from the sky and hit his right forehead. Mr. Meng underwent suture surgery that day. During the trial, Beijing Institute of Technology said that the wind was northerly that day, and the high-rise buildings near Mr. Meng were all on the south side of Mr. Meng. It was impossible for falling glass to hit Mr. Meng. Haidian court found that the day was indeed a northerly wind of five or six grades, but after the police station arrived at the first time, it was found that there were many pieces of glass on the ground. Haidian Court held that Beijing Institute of Technology, as the manager of the building, denied that Mr. Meng was injured by the falling glass of the high-rise building managed by the school only based on the wind direction. Based on this, the court found that Beijing Institute of Technology was at fault in managing the high-rise building and sentenced Beijing Institute of Technology to compensate more than 20,000 yuan. Shenzhen glass window hit the carotid artery and almost died. According to the report of &”;Shenzhen TV Network&”; on September 12th, 2007, Ms. Zhou from Nanshan District took her two children to a stationery store to buy a dictionary the day before yesterday afternoon. When she passed through Liyuan Community of Xuefu Road, she was hit by a glass window falling from the sky and hit the carotid artery. If the police and the masses hadn&;t sent her to the hospital for treatment in time, she would have almost died. In view of the frequent similar incidents of throwing objects or falling objects at high altitude in Nanshan District, many witnesses issued the voice of &”;Don&;t let throwing objects at high altitude hurt people again&”;. The public security organs have preliminarily investigated that Ms. Zhou was smashed, which was caused by the fact that the marketing staff of the cosmetics company on the fourth floor of Xuefu Road in Liyuan Community were training, because there was no air conditioner in the house, and when an employee surnamed Zhang opened the window to enjoy the cool, let the air breathe and then closed the window, the glass window fell down. On the one hand, they hope that the public security organs will seriously handle affairs and punish the perpetrators according to law, so that the perpetrators and other citizens who have thrown objects at high altitude can learn from them. Witness Mr. Wang: I heard that before,A child was hit by a parabolic object, which was also on the south side. I feel that this should not happen again. (2) Falling glass in residential buildings Hangzhou high-altitude glass fell and injured people and was fined 80,000. In 2005, the case of injury caused by falling glass in Wenzhou village, west of Hangzhou, was pronounced in the first instance of Xihu District Court on November 17. Zhongmou, the owner of Room 602, whose burden of proof is reversed and the suspicion of accident cannot be ruled out, was identified by the judge as the owner of the wounding glass. At noon on July 5, 2005, Unit 1, Building 6, Chengbei Business Park, Wenzhou Village Community, a piece of glass with a thickness of 0.5cm fell from the sky, penetrated an umbrella and hit Chen Chunxiu, a middle-road person, on the head. The doctor took out four pieces of glass from Chen&;s skull, the largest being the size of a matchbox. The police have repeatedly investigated and never found out the owner of the glass. On July 29th, the victim, Chen Chunxiu, sued the West Lake Court, claiming 85,441 yuan. Four households with defective property management and unit 1 glass in the community were all listed as defendants because of suspicion (《都市快报》 has reported the case continuously since July 6th). On September 21, the court held a hearing, and the judge showed the glass fragments and a small piece of sawdust collected at the scene. After investigation, the glass was inconsistent with several defendants, but the wood chips were completely consistent with the broken marks of the wooden windows of 602 households. At that time, Zhong argued that the sawdust belonged to his family, but the glass in his home and the falling glass were not the right color and thickness. He also took out the weather report of the day and said that there was basically no wind at that time, and it was impossible for glass to fall. The court&;s judgment refuted his statement one by one. According to the judgment, combining all kinds of evidence, according to the rule of high probability of civil evidence (that is, in a very probable case, if the suspect cannot be ruled out, the evidence is considered to be a fact), it is enough to conclude that the glass was dropped by a certain household in 602 households. There are four reasons why the owner of Room 602 is suspected of being awarded compensation. The reasons are as follows: First, the fresh damage marks of the wooden window frame of Zhongjia are completely consistent with the sawdust, which can be considered as a whole; Second, Zhong said that on July 2, he asked the decorator to check the glass in the room and installed a new piece of glass on the other side of the same window that lacked glass. According to daily experience, there are two pieces of glass missing in the same window, and it is impossible for the decorator to install only one piece, so it can be concluded that there was no shortage of window glass in Zhongjia at that time; Third, on the day of the incident, the police found that the window glass of Zhongjia was missing, which was less than three days apart from the complete condition of the glass; Fourth, there are nail holes on the wooden window frame without glass. There are two nails on the right side of the wooden window frame, and there are no objects for fixing the glass on the upper and lower left sides. It is impossible for a single nail to fix the glass, so it can be concluded that the original nail on the hole mark was lost due to the fracture of the wooden window. The judgment said that if a building or other facilities, as well as shelving and hanging objects on the building collapse, fall off or cause damage to others, its owner or manager shall bear civil liability. As the owner of the building where the glass is located, Zhong should compensate Chen Chunxiu for medical expenses of 85,441 yuan within 15 days from the effective date of the judgment. Compensation for students&; eyes injured by glass in Nanchang by ten households sitting together. On May 22, 2006, Peng Bing (a pseudonym), a middle school student in Nanchang, came back from school.Home, passing through No.46 Donghao Street, Nanchang City, was injured by a piece of glass flying upstairs, which caused the sclera of the left corner of the eye to penetrate. It was identified as disability level 7, so Peng Jia spent tens of thousands of yuan on medical expenses. Where did the accident glass come from? The police intervened in the investigation, but could not confirm which house the glass flew from. In 2007, Peng Bing sued all 12 households in Unit 1 of No.10 Middle School and No.46 in court. On June 7th, donghu district Court of Nanchang City ruled that 10 households on the second to fifth floors of the unit jointly compensated Peng Bing for more than 100,000 yuan in disability compensation and mental damages, with each household bearing 10,437 yuan. After the judgment of the first instance, 10 households shouted injustice. Guangzhou gale blew down the window and hit the shelter. On the night of August 1, 2006, an aluminum alloy glass window was suddenly blown down by the strong wind in a residential building on the middle road of Shiwan Town, and it fell from the sixth floor, and a motorcycle driver was injured and a car was smashed. The relevant departments reminded that there will be a typhoon &”;prapiroon&”; in our city in the next two days, so citizens are requested to take precautions, especially paying attention to injuries caused by high-altitude objects falling from the wind. The reporter saw at the scene of the middle road in Shiwan Town that the aluminum alloy glass window that fell was still on the smashed car, and there was a motorcycle upside down next to the car, and there were a lot of glass fragments on the ground. The police have rushed to the scene to deal with it, and the injured have also been taken to the hospital for treatment. The driver of the car told the reporter that he parked his car by the roadside and then went to a restaurant for dinner. When he came out, he found that his car was hit by a glass window falling from the air. The reporter saw that the car was not greatly damaged, but the body was scratched. According to witness Mr. Huang, the accident happened around 21: 00, when a strong wind suddenly blew and then it rained heavily. The injured motorcycle driver drove downstairs to take shelter from the rain, only to hear a muffled sound of &”;bang&”;. A glass window upstairs fell and hit the motorcycle driver&;s head, and the motorcycle driver was injured and fell to the ground. The surrounding people rushed to the police when they saw it, and then the ambulance sent the injured to the hospital for treatment. Mr. Huang said that fortunately, the injured person was wearing a helmet. After the glass window fell, the glass was broken by the helmet, but the hand was injured. Law enforcement agencies should guard against falling objects when typhoons are approaching. Recently, the Administrative Law Enforcement Bureau of Chancheng District has inspected some outdoor billboards with hidden dangers and rectified illegal and disorderly construction. They reminded the public that it is best to automatically remove illegal structures and keep the flowerpots and other sundries placed on the balcony well to avoid accidents in which passers-by are injured by falling objects from high altitude when the typhoon blows them off. Relevant units should also reinforce some outdoor advertisements or outdoor signboards. In the residential area of Shanghai, throwing glass at high altitude broke four fingers of women. According to the report of &”;Oriental Net&”; on July 31, 2007, at about 5: 30 this morning, a woman suffered a &”;natural disaster&”; in the downstairs of Meilin apartment in Yangpu District, Shanghai: someone dropped a thick piece of glass from the sky and just hit her right hand, causing four fingers of the woman to break. According to Xuan Kegui, a reporter from SMG News Center who rushed to the scene, the roadside downstairs was covered with blood, and a piece of thick glass was broken into several pieces. Witnesses said that if the glass hit the head, the injured person would have died. The injured woman&;s name is Dong Fang, this year26 years old, from Xuancheng, Anhui. After examination and diagnosis by the hospital, four fingers of the injured person&;s right hand were broken, which was a comminuted fracture and needed to be replanted by surgery. It is still uncertain whether the fingers can be saved. Meilin Apartment is a 20-story building. Residents nearby said that there are often some uncivilized residents in the building who throw rubbish and sundries from the sky. Moreover, incidents of throwing objects at people have happened before. At present, the relevant departments are investigating the identity of the perpetrator. (3) Glass curtain wall building falling glass Guangzhou glass burst accidents frequently occur &”;hail&”; from falling glass in the building. According to th《信息时报》 on September 13th, 2006, at noon yesterday, a piece of tempered glass on the 22nd floor glass curtain wall of Kangfulai Building, No.313 Yanjiang Middle Road, Yuexiu District suddenly burst, and the broken glass smashed three cars on the road. Fortunately, no casualties were caused. Experts suspect that the glass bursting is related to the recent sudden drop in temperature. In recent years, the glass curtain wall with tempered glass as the main body has appeared more and more in some large buildings, but the subsequent safety accidents such as &”;light pollution&”; of the glass curtain wall and personal injury caused by glass bursting have also made the glass curtain wall a &”;sword&”; hanging over people&;s heads. Experts pointed out that the total area of curtain wall glass in Guangzhou has exceeded 10 million square meters. Under the embarrassing situation of difficult detection and lack of maintenance institutions, strict quality control can fundamentally reduce the occurrence of safety accidents. The building suddenly flew under the glass &”;hail&”;: At 12: 30 noon yesterday, Mr. Su, a citizen, passed by the sidewalk opposite the Kangfulai Building in Yanjiang Middle Road. Suddenly, with a crisp sound, a large piece of broken glass was sprinkled over the road next to it, and it was firmly smashed on three moving cars. Mr. Su was hit in the foot by some flying pieces of glass. The reporter saw in front of the building that the driver Mr. Liu&;s van was seriously damaged and a clear crack was smashed in the middle of the front windshield. He said that the broken glass must be replaced, otherwise the vehicle will easily burst and hurt people when driving at high speed. The driver, Mr. Chen, has a &”;pockmark&”; on the front windshield of the red taxi, and the corner of the rear hood is also damaged. Mr. Chen said that at that time, I felt a dense &”;hail&”; overhead, and the glass smashed on the car. The office glass suddenly burst: It is understood that the burst glass belongs to the 22nd floor of the building. From the downstairs, the glass fragments on the frame have been removed, and a wooden board is temporarily used to keep out the wind and rain. The reporter went up to the 22nd floor. The broken glass was in the office of the chairman of a clothing company on this floor. It was about 1 meter wide and 1.2 meters high. It was originally fixed on the frame. There is also a lot of broken glass on the office floor. It is said that the whole piece of glass was scattered after it burst. According to the employees of the company, there was no one in the office at the time of the incident, excluding man-made sabotage, and there were no signs of broken glass before. It is suspected that it is caused by glass aging, quality reasons or sudden climate change. The exterior wall of the whole building is a glass curtain wall, and the building management said that the specific reasons need to be investigated. Relevant managers said that similar accidents had never happened before, but some managers shook their heads and said they didn&;t know whether the glass curtain wall of the building was tested regularly. The temperature changes suddenly, and the glass is easy.Burst: Why does tempered glass with smooth and flat appearance suddenly burst? Professor Deng Zaide from the School of Materials Science of South China University of Technology believes that it may be related to the sudden change of temperature in recent days. It was extremely hot in Guangzhou a while ago, but the temperature has plummeted in the last two days. This alternation of hot and cold is most likely to lead to glass bursting, because the expansion coefficient of the metal frame fixing the glass is greater than that of the glass. When the temperature changes greatly, the glass changes less than that of the metal, and it will be broken due to strong distortion. Tempered glass bursting caused by the change of temperature and the influence of typhoon is common in southern cities such as Guangdong, Fujian and Shanghai. It will not be detected in use: in July 2006, the whole glass curtain wall of Ms. Lan Qingju Qin&;s house in Haizhu District suddenly burst and the whole glass was seriously damaged. It is said that on April 23, 2006, a large piece of glass fell from the glass curtain wall on the 30th floor of the residential area. The broken glass smashed the balcony glass on the 11th floor, smashed the sunshade below, and punctured a hole in the steel pipe for drying clothes. In China and even in Guangzhou, it has happened more than once that the glass fell from the sky, injuring people and destroying things. An embarrassing situation is that the units that have accidents generally have not systematically tested the glass. Professor Deng Zaide said that the biggest problem at present is that the detection of tempered glass is difficult and complicated, and there is a lack of corresponding maintenance institutions, so that the glass can only be replaced after the tempered glass injury accident, and the lack of prior prediction is tantamount to &”;mending after it is too late&”;. According to reports, although China has professional testing institutions for tempered glass and testing standards, it is also very troublesome because of its complicated operation. Therefore, tempered glass is basically not tested in use except for some random inspection when it leaves the factory. It is precisely because of technical reasons that there is no special maintenance organization in China at present. However, the general users usually just clean the surface for maintenance, and there is no way to know the quality of the glass itself. Glass curtain walls should be inspected once every five years: it has been pointed out that the service life of tempered glass is 20 years, while the extensive use of tempered glass in big cities such as Guangzhou and Shanghai in China can be traced back to the 1980s. It seems that it just happens that the service life has expired, and there have been many incidents of tempered glass wounding in recent two years. Professor Deng Zaide believes that there is no conclusion or standard about its service life in the world at present, generally speaking, it is about twenty or thirty years. Some experts believe that glass curtain wall buildings should be tested once every five years. Guangzhou has not yet restricted the glass curtain wall: In view of the frequent incidents of glass bursting and even wounding, Beijing, Shanghai and other cities have also restricted the use of glass curtain walls and promoted safe new material curtain walls. At present, there are no relevant restrictions in Guangzhou, but developers are not encouraged to use glass curtain walls in large areas when developing real estate. In recent years, relevant information shows that in 1999 alone, there were many incidents of casualties caused by glass bursting in Beijing. In 2003, a survey of large and medium-sized glass curtain walls in Shanghai showed that about 90 of the 931 inspected buildings had potential safety hazards. Jiangsu high-altitude glass curtain wall is crumbling, Taizhou fire is tight.Emergency evacuation. According to &”;Hubei Fire Information Network&”;, on the morning of June 29th, 2007, after a heavy rain, two outer wall glasses on the 9th and 11th floors of New Era Kyushu Commercial Building in Taizhou City, Jiangsu Province burst. More than 100 kilograms of glass may hurt people at any time. The public security and fire departments worked together for more than two hours, and finally eliminated the danger, causing no casualties. At 11: 30 in the morning, under the New Era Kyushu Commercial Building at the intersection of Qingnian Road and Dongjin Road in Taizhou City, three staff members looked nervous. While contacting the upstairs staff with walkie-talkies, they signaled passers-by to make a detour. Police and firefighters set up a cordon to evacuate vehicles and people. A staff member pointed to the ninth and eleventh floors and said, &”;The glass on the outer wall is cracked, and it will fall at any time, so stand away.&”; According to the on-site staff, the cracked glass is located in the conference room of a real estate company on the ninth floor. The outer wall of this conference room is installed with tempered glass more than 2 meters high and 1.5 centimeters thick. It was sunny that morning, and the conference room was air-conditioned. At 11 o&;clock in the morning, after a heavy rain, he suddenly heard a loud bang, and then found that the outer wall glass was broken. At 12: 20 noon, the staff responsible for maintaining order downstairs reported that there were more and more people onlookers, which had caused traffic jams and must be done. The rescue personnel of the public security and fire departments at the scene decided to smash the glass from the building to eliminate the danger. By 12: 30, the danger on the ninth floor was eliminated. Four barrels of glass fragments were removed from the site. Another piece of cracked glass is located in the sealed roof on the eleventh floor, and there is no passage to connect it. The outdoor wind is very strong, and the fire ladder can&;t rise to the right height, so the danger can&;t be ruled out from the outside. Firefighters broke through a wall and entered the rooftop. However, firefighters found that the glass on the eleventh floor was different from the tempered glass on the ninth floor, and it was double-layer insulating glass. The cracked glass was located in the outer layer, and the glass in the inner layer was intact. If you knock from indoors, it will cause six surrounding glasses to crack together. Rescuers decided to suspend the demolition, first stepped up their vigilance downstairs and waited for professionals to come to remove the danger. A person in charge of the real estate company said that these glasses were installed by a manufacturer in Luoyang and have been installed for more than a year. Each piece of glass weighs more than 100 Jin. A few days ago, a glass burst and fell off a tall building. Fortunately, no casualties were caused. Unexpectedly, the same thing happened again. (4) Glass falling from a construction site in Chengdu, and the &”;glass rain&”; workers became bloody. According to a r《华西都市》 on July 11th, 2006 titled &”;Injury caused by falling objects from high altitude happens again, and the safety problem of the construction site cannot be ignored&”;, yesterday afternoon, an accident happened at a construction site in Xihuamen Street, Chengdu. When the workers were installing the outer window glass, the whole glass was broken, and the extremely sharp broken glass rained down, and a worker downstairs was hit by a piece of glass, which immediately made him bloody. Scary high-altitude &”;glass rain&”; hit the workers: &”;Wow!&”; At 11 o&;clock in the morning yesterday, an office building site in Xihuamen Street suddenly heard the crisp sound of heavy objects falling. When a glass curtain wall was installed, it suddenly collapsed somehow, and hundreds of kilograms of glass fell from the sky.A worker under construction was knocked unconscious by the &”;glass rain&”; on the spot. When the reporter heard the news, he rushed to the incident site and saw that the hanging basket for installing the glass curtain wall fell to the ground, and broken glass was scattered everywhere, and the glass slag was soaked with blood. A worker told reporters that the hanging basket was parked on the seventh floor to install a curtain wall, and there were workers cleaning up the muck directly below. Suddenly, a piece of glass just installed on the seventh floor suddenly broke and fell off and collapsed. The extremely sharp piece of broken glass fell from the sky, and the worker below was unaware of it. The nearby workers shouted: &”;Run, the glass is broken!&”; But the tragedy still happened. The glass was smashed on the worker&;s head, only to hear a scream from the worker, and he fainted on the spot. &”;We were so scared that we quickly went over and opened the broken glass slag and called 120 for help!&”; According to a witness resident nearby, he heard a noise coming from the construction site and then saw an ambulance coming. But strangely, the door of the construction site was locked and the ambulance was not allowed to enter. After a while, several workers carried a man with blood all over his head into the ambulance. Save your life after 3 hours of operation: The reporter then rushed to the Third Hospital of the City. According to the attending doctor, the situation of the injured was terrible at that time: the top of the head was covered with large and small wounds, and blood kept coming out, which was very critical. Since 2 pm, brain surgeons have operated on the injured workers for more than three hours, and finally saved the lives of the injured. It is understood that the injured worker surnamed Liu is 21 years old this year. Watch out for frequent &”;high altitude&”; in construction sites: According to experts, construction sites are prone to injuries caused by falling objects from high altitude. When installing or disassembling tower cranes, external elevators and installing glass curtain walls in these places, the operation time should be strictly controlled to strengthen safety protection. For the projects under construction which are located in downtown areas, facing the street and other crowded people, as well as the projects with high risks such as deep foundation pits and tall formwork under construction, it is necessary to check and implement safety precautions: First, it is necessary to regularly check and fasten objects that are easy to fall, such as billboards and balcony items, to ensure their firmness and reliability; Second, pedestrians should try to stay away from places where falling objects may occur. When the construction workers on the construction site can&;t stay away because of working conditions, they should strengthen self-protection and wear safety helmets. (5) sundries fall upstairs in Beijing and throw flowerpots at innocent people. According to th《北京晚报》 on September 21st, 2007, at 3pm on the 20th, Ms. Jin was hit in the head by an empty flowerpot dropped from Building No.10 in the No.32 courtyard of Xueyuan South Road, and now she has been admitted to the nearby Second Artillery General Hospital. At 5 o&;clock in the afternoon, Ms. Jin&;s friend Mr. Zhang guided the reporter to the scene. There was a pool of blood five or six meters away from the residential building, and there were a few locks of curly hair about 30cm long next to the blood, and flower pot fragments were scattered. The accident happened in the middle of Unit 1 and Unit 2 doors of the residential building. There were no guardrails installed in the windows above the third floor of the residential building, and no households placed flowerpots on the windowsill. In the inpatient ward of the Second Artillery General Hospital, Ms. Jin&;s clothes, which had just been stitched up, were stained with blood, and the palm-sized gauze wrapped her head. She said that her head still hurts, half of her body is numb and her ears are buzzing. Her lover, Mr. Liu, introduced that two people at that time.I am waiting for Mr. Zhang downstairs with my back to Building 10. &”;Just as I turned my head, a black shadow fell down.&”; Then Ms. Jin was smashed to the ground, and she couldn&;t speak for a minute. &”;Someone must have thrown the flowerpot down on purpose.&”; Mr. Liu said: &”;There was no strong wind at that time. Besides, we were five or six meters away from the residential building. If we fell by ourselves, we should just land near the residential building. How could we run so far?&”; Residents in the courtyard said that it was not a day or two since things fell from Building 10. Half an hour before Ms. Jin&;s accident, she dropped three empty flowerpots from upstairs. The staff of the neighborhood Committee said that before Ms. Jin was injured, a taxi parked downstairs was also killed. &”;Throw rubbish, beer bottles, flower pots and other sundries from upstairs.&”; The staff introduced: &”;We have also posted notices in residential buildings asking everyone not to throw things downstairs. But the situation has not changed. I hope the public security department can investigate. &”; 21 households in a building injured by falling objects in Wuhan paid 170,000 yuan for &”;sitting together&”;. According to a r《长江日报》 on January 19th, 2007, an ashtray fell from the upstairs of Wuhan and hit the head of a middle-road person. Yesterday, it was learned that 21 households in the building were awarded a joint compensation of 170,000 yuan because they could not prove that they did not throw the ashtray. One night in August, 2006, Zeng Xiaolong was walking on the sidewalk beside the road when a glass ashtray fell from the sky and hit him in the head. Zeng Xiaolong spent 170,000 yuan on medical expenses due to brain injury. After investigation, the ashtray was thrown from the window above the second floor of a residential building on the road, but 23 households above the second floor refused to admit that they had thrown the ashtray. 23 households were brought to court. During the trial, only two families proved that they had never lived here, and the other 21 families were sentenced to jointly bear the compensation. The strong wind in Chongqing blew off the heads of passers-by with umbrella handles in high-rise buildings and died on the spot. On August 1st, 2007, Wang Jiucheng, from No.1 Beishan Road, Wanzhou, Chongqing, was buying medicine in a pharmacy when a strong wind suddenly blew. He hurried home to collect his clothes. Suddenly, an umbrella handle fell from the sky and was inserted into his head impartially, causing him to die on the spot. According to th《重庆商报》 on August 3rd, 2007, the day before yesterday, Wang Jiucheng, who lives in No.1 Beishan Road, Wanzhou, Chongqing, bought medicine in a pharmacy. When he saw a sudden gale, he hurried home to collect his clothes. When passing through a residential building, the tragedy happened: an umbrella handle fell from the sky and was impartial to his head, causing him to die on the spot. Whose house fell the hooked umbrella handle? At present, no one recognizes the account. The family wants to claim the funeral expenses from the residents of the whole building, and the police have launched an investigation. When I went home to collect clothes, something happened: According to Chen Mou, a neighbor of Wang Jiucheng, at 3 o&;clock in the afternoon, he went to a pharmacy in a branch road in Beishan to buy medicine, and when he met Wang Jiucheng, he also came to buy medicine. They talked a few words, just then the weather suddenly changed and the wind suddenly blew. Wang got up and left and said that he would go home to collect the clothes hanging on the balcony. According to another witness, when Wang Jiucheng trotted downstairs at No.1, No.17, Beishan 1st Road, suddenly, with a bang, an &”;iron hook&”; fell from the upstairs and stuck in his head, causing him to fall to the ground. see with one&;s own eyesThe caller hurriedly dialed 120 for emergency treatment. Because the head of &”;Iron Hook&”; Wang was too deep and the ambulance had not arrived, Wang stopped breathing. According to the identification of the family members of the deceased, the &”;iron hook&”; is a large umbrella handle, more than 1 meter long, and the part inserted into the head is very sharp. Will claim the funeral expenses from the whole building: The reporter learned that the residential building where the iron hook fell is a 9-storey building, facing the house where Wang Jiucheng lives, separated by a dam more than 10 meters wide. However, after the incident, none of the residents in the building admitted that the &”;iron hook&”; belonged to their own home. Yesterday, Ms. Lu, the family member of the deceased, said that she hoped that the owner of the &”;iron hook&”; could take the initiative to stand up and face this tragedy together, because no one wanted anything to happen. She said that if she refused to accept the payment, she would claim compensation for funeral expenses and other related compensation from the residents in the whole building. According to the person in charge of the Beishan Police Station of Wanzhou District Public Security Bureau, the wind was very strong at the time of the incident, and many high-rise buildings had fallen. After preliminary investigation, the &”;iron hook&”; was blown by the wind. Different owners of parabolic objects at high altitude do not bear criminal responsibility: In this regard, lawyer Ni Shijun of Chongqing Jinyang Law Firm said that if the &”;iron hook&”; was blown down by the wind, the owner would bear civil liability for the damage result, because it is different from throwing things at high altitude artificially, so it does not bear criminal responsibility. Lawyer Ni also said that if the &”;iron hook&”; is not improper in terms of placement and storage, and it is purely caused by strong winds, it is a force majeure event and can be exempted from liability. High-altitude parabolic objects in Xuzhou affect the surrounding environment and bring potential safety hazards. According to th《徐州日报》 on September 18th, 2006, a staff member of Jinxiu Jiayuan Property Management Office called to report that there have been many high-altitude parabolic phenomena in this community recently, which have affected the surrounding environment and brought certain security risks. One day in April, Wang Fuyun, a cleaner in Jinxiu Jiayuan, was cleaning downstairs on the 5th floor, and his back was hit by a glass bottle thrown upstairs. Because many residents upstairs opened the windows, they simply didn&;t know which household had dropped the bottle. On July 19, the sauce left by the residents of Building 6 polluted the external wall on the east side of the building and the air conditioners on the 27th and 28th floors of the building. The property management company had to invite someone to clean the dirt on the wall the next day. According to manager Liu Feng of Jinxiu Jiayuan Property Company, in order to clean up the dirt on the east outer wall of Building No.6, they spent nearly 1000 yuan&;s cleaning fee. As no one can be found to throw garbage, the property management company can only post some publicity and education slogans. &”;Many communities have parabolic problems at high altitude, but it is difficult to find out who throws garbage. Property managers only have to let cleaning staff clean it several times.&”; Liu, director of the property management department of the Yellow River Jingyuan Community, said that there have been incidents of throwing objects at high altitude in the past. Because it is difficult to obtain evidence, most of the cases were dropped after the police received them. Wai Shum, a lawyer of Xuzhou Yixing Law Firm, believes that throwing objects at high altitude is only a moral issue at present. To prevent such incidents, relevant laws and regulations should be formulated to impose strict penalties on serious throwing events. Falling objects frequently hurt people in Tianjin&;s 6-level gale. On December 16th, 2006, Tianjin &”;Jinbao. com&”; received 11 falls from Heping, Hexi, Hedong and Hongqiao from 9: 00 to 6: 00 pm.The report that things hurt people and hurt things. The window glass that was not closed was smashed and fell by the wind, and flowerpots, clothes hangers, etc. fell from the sky, which not only injured many passers-by, but also damaged three cars. In addition, the roofs of mobile homes in construction sites near Er Nankai Middle School and Nankou Street were blown off by the wind, which affected the traffic for a short time. Iii. Relevant administrative measures At present, the relevant local construction administrative departments mainly adopt three major measures: &”;installing safety glass, replacing glass curtain walls that fail to pass, and pasting films that cannot be replaced&”;. 1. Safety glass For the use of safety glass in high-rise buildings, the main conc—— strength and is not broken when it is in working condition; Second, the glass has anti-collision and scattering properties, which ensures that it will not fall, fly and scatter when it is in a broken state, and will not be scattered; Third, the glass has a destructive form that is not easy to hurt people, avoiding large sharp fragments and being obtuse, smooth and small particles. No matter what form of glass fragments are scattered from high-rise buildings, they are dangerous and even fatal. One characteristic of tempered glass is that the pre-heating stress can not be completely eliminated, so it has a self-explosion rate of 1/000 ~ 1/000, and its failure is without warning. In this way, the self-explosion and breakage of glass and the high-altitude scattering have become the basic technical basis for the unsafe use of (all-) tempered glass in the glass curtain wall of high-rise buildings. Therefore, it is considered safe to use (full) tempered glass at a certain height, but it should be considered unsafe to use it above a certain height. Houses with floor-to-ceiling windows are prone to danger. Nowadays, there are more and more houses with large windows and low windowsills, and more and more houses with floor-to-ceiling windows are used. However, the existing security problems cannot be underestimated. If the strength of the fixed window frame is not enough, the glass will be broken if the user leans lightly on the window frame; Floor-to-ceiling windows only use fixed glass, and there is no necessary protection. Normal activities such as children playing and chairs falling over will break the glass, causing danger; When floor-to-ceiling windows are used in the high-rise apartment of high-rise buildings, if there is no necessary protective facilities, the elderly generally reflect dizziness when looking out. As long as similar situations cause complaints, designers must bear certain responsibilities. According to the regulations, safety glass should be used for window panes with an area of more than 1.5㎡ or floor-to-ceiling windows with the bottom edge of glass less than 500㎡ from the final decoration surface. Therefore, when buying the floor-to-ceiling glass window with fixed fan, it is necessary to determine whether the product has taken practical safety protection measures. On December 4th, 2003, the State, Ministry of Construction, AQSIQ and State Administration for Industry and Commerc《建筑安全玻璃管理规定》. Th《规定》 requires that, from January 1, 2004, structures such as new construction, expansion, renovation, decoration and maintenance projects in cities above the prefecture level (including prefecture level) should be installed with safety glass according to th《规定》. Construction, construction units to purchase safety glass for buildings must have a mandatory product certification mark (CCC mark) and provide a copy of CCC certificat《规定》 refers to tempered glass, laminated glass and other glass products, such as safety insulating glass, which meet the curr《规定》 pointed out that safety glass must be used in the following eleven parts of buildings that need glass as building materials: first, windows should be opened outside buildings with 7 floors and above; Second, the window glass with an area of more than 1.5 square meters or the floor-to-ceiling window with the bottom edge of the glass less than 500mm from the final decoration surface; The third is curtain wall (except full glass curtain); Fourth, inclined assembly windows, various ceilings (including skylights and lighting roofs) and suspended ceilings; Fifth, sightseeing elevator and its peripheral protection; Sixth, indoor partition, bathroom enclosure and screen; Seventh, the railings of stairs, balconies, platform corridors and the railings in the atrium; The eighth is the floor board used to bear pedestrians; Nine is the observation window and observation hole of aquarium and swimming pool; Ten is the entrance and exit of public buildings, halls and other parts; Eleven are other parts that are vulnerable to impact and impact and caus《建筑玻璃应用技术规程》 (JGJ 113) and 《玻璃幕墙工程技术规范》 (JGJ 102). 2. Energy-saving and Safety window film At present, energy-saving and safety window film is widely used in Shanghai and other places. According to Wei Guochang, vice president of Shanghai Real Estate Research Institute, they have done a lot of research on energy-saving and safety glass films, and found that Safe window film has unique advantages in energy saving. After 16㎡ indoor window film, it can save electricity by 0.24 degrees in 24 hours. If the housing area of Shanghai property management is 120.81 million ㎡, 50% of the room rate will be deducted, and the living area will be 60.4 million ㎡. Considering 50% of window film, it can save electricity by 0.24× 30200000 ÷ 16 = 447400 kWh a day. In the long run, the above figures are considerable. According to statistics, the annual glass production in China is about 13.44 million ㎡. Except for 16% ~ 18% of the deep-processed glass, the remaining 11.02 million ㎡ pieces of original glass are directly used in the fields of architecture and decoration, which undoubtedly provides a larger market space for safe window film. Safe window film is not only suitable for new buildings, but also has a unique effect on renovating existing buildings. This window film can be easily attached to the existing window glass system without adding any expensive equipment. It is a cheap, time-saving, energy-saving and safe material for rebuilding old building doors and windows. 3. Initiatives of local construction administrative departments On October 7, 2007, Sun Jianping, deputy director of the Shanghai Municipal Construction and Transportation Commission, announced that the special rectification of glass curtain wall buildings in this city has entered the second phas—— rectification. Since August, among the more than 1,000 high-rise buildings that have received the self-inspection notice, 211 buildings have not found problems and 330 buildings have been self-inspected.Out of the buildings with hidden dangers, 201 buildings have completed preliminary rectification. Self-inspection is mainly aimed at glass curtain wall buildings that have been put into use for more than 5 years. The main safety hazards of existing glass curtain wall buildings are: opening window glue, sealing strip, stress component, rainwater leakage and using unsafe glass. Because the glass curtain wall will pose a serious threat to the public once it bursts or falls from the sky, a series of effective measures have been taken to make up for the long-lived glass curtain wall without problems. At present, all new buildings must be equipped with safety glass, but the glass curtain wall that does not pass the customs must be replaced, and those that cannot be replaced should be protected by pasting film to prevent rupture and personal injury. At present, the Shanghai Municipal Construction and Transportation Committee has listed 12 things that threaten the safety of the city and have hidden dangers. The rectification phase of glass curtain wall will end in March 2008, and the rectification of air conditioning outdoor units will be carried out before the flood season in 2008. Guangzhou Municipal Construction Committee stipulates that from June 1, 2005, safety glass must be used in eight types of buildings newly built, expanded and rebuilt. According to Li Dapeng, deputy director of the Building Materials Department of Guangzhou Construction Committee, there are currently more than 3,000 buildings with more than 20 floors in Guangzhou, among which glass curtain wall buildings account for a considerable proportion. In order to save costs, developers use ordinary glass in the middle of the place where safety glass should be used, resulting in frequent incidents of falling and injuring people. The hidden dangers cannot be ignored, especially in Guangzhou, which is a typhoon-prone area. At present, the anti-theft net is being dismantled in Guangzhou, and the use of safety glass will help to prevent theft. In addition, safety glass can play an active role in preventing noise interference, ultraviolet radiation and building energy conservation and consumption reduction. Guangzhou also stipulates that if the buildings and structures completed and used before June 1, 2005 do not meet the specified requirements, their owners or managers should take corresponding measures within 10 years (within 2 years of glass curtain wall) to meet the technical requirements of building safety glass. Undoubtedly, this regulation provides great business opportunities for safety glass and safety window film products. Discussion on the legislation of falling objects from high altitude 1. The elements of joint dangerous behavior include: first, several people have committed joint dangerous behavior; Second, the dangerous behavior of several people may cause damage results; Third, the damage has occurred, but I don&;t know who caused it; Fourth, the actor has no legal defense. &”; On the objective elements of joint dangerous behavior (several people commit joint dangerous behavior), there are two propositions: &”;the common theory of behavior&”; and &”;the unknown theory of the perpetrator&”;. The former emphasizes the relevance of behavior in time and place, while the latter emphasizes the uncertainty of the perpetrator. But no matter what kind of theory, we must first solve a problem: what is a common dangerous behavior? Some experts have made a comparative analysis of this: one of the cars driving on the same road hurts people, just like one person in the dormitory is on fire, which cannot be considered as a common dangerous behavior, but if two cars are speeding, they are considered as a common dangerous behavior, which means that racing on the road is a dangerous behavior. Visible, the so-called &”;common&”;, its true meaning is that the behavior of several people are related to a dangerous behavior, becauseTherefore, the judgment of joint liability of joint dangerous behavior is based on whether the actor participates in the dangerous behavior and whether the dangerous behavior causes harm. On the one hand, if a dangerous act causes harm, the actor shall bear the responsibility; On the other hand, as long as the actor participates in joint dangerous behavior, he will bear joint and several liability. The purpose of its regulation is to deal with the dilemma that causality is difficult to identify, so as to protect the victims. In this regard, the victim must first prove that several people participated in the dangerous behavior, and there is an alternative causal relationship between the dangerous behavior and the damage result, in order to realize his claim that these dangerous behavior participants should bear joint liability. In the case of Wang in Beijing, there are indeed several households whose windows have glass defects. If the victims of these households can prove that they are at fault for the glass defects, they can indeed claim joint and several liability from these households, but it is obviously inappropriate to directly investigate the responsibility of all households in the whole building. In the case of Chongqing Hao, the victim did not prove that several people participated in the dangerous behavior of throwing ashtrays, so it is obviously a misunderstanding of the theory of common dangerous behavior to ask the residents of the whole building to prove that they did not participate in the dangerous behavior of throwing ashtrays. 2. Collective Responsibility Common Dangerous Behavior is only one kind of collective responsibility theory, but not all. In China, there are joint injurious acts besides joint dangerous acts, and in American tort law, the theory of collective responsibility contains four independent legal principles: the principle of concerted action (the same as the joint injurious act in China), the principle of selective responsibility (the same as the joint dangerous act in China), the principle of corporate responsibility and the principle of market share. The four legal principles contained in &”;collective responsibility&”; have a lot in common under applicable conditions. First of all, the special circumstances of the case make it impossible for the plaintiff to prove which specific defendant&;s fault caused the damage; Secondly, the defendants who are required to bear collective responsibility must all participate in the negligent behavior that can lead to the same damage result; Thirdly, the problem of evidence must be related to negligence or unqualified products themselves; Finally, a very important question that should be considered when deciding whether to use the theory of collective responsibility is whether we have other effective remedies or procedures to make the victims get reasonable economic compensation. &”; Judging from the expression of American tort law, whether the victim can&;t get compensation through other remedies is only a reference point for whether collective responsibility can be applied, but it is by no means the only reference point. When applying collective liability, we must first consider whether several defendants have participated in the negligent behavior that can lead to the same damage result. If this is not proved, then collective liability cannot be applied even if the victim does not have the relief that can get appropriate compensation. It can be seen that it is a prerequisite for the application of collective responsibility that several defendants have participated in negligent acts that can lead to the same damage result. Accordingly, it is obviously inappropriate for the victim to list the whole floor residents as defendants in the Beijing Wang case, but there is no legal basis for the victim to list the whole floor residents as defendants in the Chongqing Hao case. Because, the victims of the two cases can&;t prove that all the defendants they listed participated in the wrong behavior that could lead to harmful results. 3. The General Principles of Civil Law and Property Law are closer.In 2000, high-rise buildings in many parts of the country were killed and injured by throwing objects from high altitude. In China, there are laws against throwing objects or falling objects from high altitude. Article 126 of 《民法通则》 clearly stipulates that if falling objects from high altitude cause personal injury, they shall bear civil liability for comp《民法通则》, th《物权法》, and both the house owners and the community managers have the responsibility to maintain safety. From the incident that Ms. Zhou was smashed on September 12, 2007, the owner or landlord of the house, Miss Zhang, an employee of the cosmetics company who caused the accident, and the merchants who designed and manufactured the glass windows may bear legal responsibilities. Adjacent to it, whether the perpetrator is subjective or unconscious, and whether it causes personal and property damage or not, it is illegal in the aspect of overhead throwing management punishment; In Shenzhen, there are also many high-rise buildings, throwing objects or falling objects at high altitude. As long as it doesn&;t hurt people, it may not be investigated. This may be one of the important reasons why throwing objects at high altitude is getting worse and worse, and it has not been effectively restrained. We believe that a more detailed and operational specification may reduce the occurrence of falling (throwing) objects from high altitude. 4. Inversion of Evidenc《最高法院关于民事诉讼证据的若干规定》, where buildings or other facilities, as well as shelving and hanging objects on buildings collapse, fall off and cause injuries, the owner or manager shall bear the burden of proof without fault, that is, inversion of evidence. There was a case in which a cleaner in Chengdu was hit by flying stones while working downstairs, and 72 households on the 18th floor were all defendants. Lawyers said that if the perpetrators did not take the initiative to take responsibility, 72 households on the 18th floor of the unit would become defendants in this case. If 72 families can&;t prove that they have nothing to do with the case, they can be presumed to be at fault, that is, the proof is reversed. In the end, the victim cleaner won the case and 72 owners were liable for compensation. Here, I would like to remind people that throwing objects at high altitude involves not only civic morality, but also legal responsibility. You must not take any chances and never throw things downstairs. Even if you don&;t take responsibility, you will be punished by law, and the victims can get justice for themselves. 5. Property management In the process of property management services, owners often receive complaints about high-altitude parabolic objects. As the owner, it is unreasonable and unreasonable to blame the occurrence of high-altitude parabolic objects on the poor management of the property management unit and ask the property management unit to bear the resulting losses. In the process of property management services, we often receive complaints from owners about throwing objects at high altitude. As the handling measures for property management units to complain about high-altitude parabolic objects, it is more important to strengthen publicity and guidance. Through various publicity on the dangers of high-altitude parabolic objects, the lessons and legal responsibilities brought by high-altitude parabolic objects are expounded with practical cases, so as to touch people&;s numb and even sleeping nerves and hearts, so as to minimize the uncivilized behavior of high-altitude parabolic objects, and finally guide a civilized and healthy life and create a harmonious humanistic living environment. As the owner, the occurrence of high-altitude parabolic objects is attributed toIt is unreasonable and unreasonable to ask the property management unit to bear the losses caused by the poor management of the property management unit. The property management unit and the owner have an equal legal relationship based on the property service contract. The property management unit provides property management services for all owners in the community according to the agreement of the property service contract, implements the property management mode combining the owner&;s autonomy and professional management, and repairs, maintains and manages the houses and supporting public facilities and equipment and related venues, so as to maintain environmental sanitation and order in public areas. As for throwing objects at high altitude, it is an individual behavior of individual households, which is an undisciplined performance regardless of collective interests, causing inconvenience to other owners and even damage to life and property. In fact, it has infringed on the rights and interests of the injured owners, and this behavior should belong to the owner&;s neighborhood infringement dispute. The rights and obligations entrusted to the property management unit by laws and regulations are &”;informing, stopping and reporting&”;. First, the property management unit informs the owner of this uncivilized behavior through various forms of publicity such as signs, propaganda pictures and texts. Secondly, the property management unit should immediately take effective measures to stop or rectify the phenomenon of throwing objects or falling objects at high altitude. As for the neighborhood infringement disputes caused by throwing objects at high altitude, On the one hand, the property management unit should report to the relevant authorities in time, on the other hand, it should actively coordinate the two sides to solve the problem through consultation based on the principle of friendly and harmonious neighborhood. If consultation fails, it can help the victims to solve it through legal channels. Many property management offices have posted &”;warm tips&”; for &”;high-altitude parabolic objects&”;, but the results are not great. The parabolic objects turn a blind eye, while the parabolic objects turn a deaf ear and still go their own way. The key is the lack of legal constraints and deterrence. Parabolic objects at high altitude are common in many cities in China. Apart from harm, &”;parabolic objects at high altitude&”; will also cause personal injury and psychological fear, but it lacks specific legal constraints. Although &”;throwing objects from high altitude&”; kills people, its consequences are no different from the crime of injury. Therefore, it should be an urgent task for local legislation to investigate the responsibility of &”;throwing objects from high altitude and trying to hurt&”;, set up an admonishing institution and carry out intensive education for offenders. 6. The public suggested that many city residents appeal: Don&;t let &”;throwing objects at high altitude&”; hurt people again. More people are concerned about how to prevent high-altitude parabolic objects. Many citizens pointed out that legal provisions should be formulated for parabolic behavior at high altitude as the basis for punishing the perpetrators and compensating the victims, and it is clear that the department is responsible for supervision and handling this matter. It is suggested that conditional communities should install electronic monitoring equipment in public places. When planning and designing high-rise buildings, we should stay away from sidewalks as far as possible, and add a podium or install a awning on the lower floor, which is also an effective means to prevent people from being injured by throwing objects at high altitude. It is generally believed that the fundamental way to solve parabolic problems at high altitude lies in legislation and improving the quality of citizens. V. Conclusion Falling objects from high altitude has become a major social hazard, seriously affecting people&;s living environment and the safety of life and property. It is particularly important to inject the connotation of safety and order into the planning to achieve the urban development goals. In this respect, China can learn from Singapore&;s successful experience, and as long as the behavior that poses a potential threat to the safety of citizens&; lives and property will beMust be restrained and controlled. Parathrowing at high altitude is not only a matter of morality and quality. If there are no clear laws and regulations to restrain it, those who lack moral awareness or low quality will relax their self-discipline, and the victims will not be able to use legal weapons to protect their legitimate rights and interests. While strengthening social propaganda, guidance and education to improve residents&; moral quality, we call for improving and perfecting relevant laws and regulations as soon as possible to safeguard residents&; good living environment and legitimate rights and interests. Therefore, it is urgent to legislate on falling objects from high altitude.
