Since July, as many provinces in China have entered the midsummer, they have ushered in a period of frequent thunderstorms. Recently, Mr. Zhao, a resident of a certain district in eastern Beijing, told this reporter that many high-rise residential residents in the community have dismantled indoor lightning protection devices. On July 6, a reporter survey found that such a phenomenon is not a case in the community. The lightning protection experts of the Beijing authorities told reporters that the private demolition of indoor lightning protection devices violated China's "Lightning Protection Design Code for Buildings" and other related regulations, and the hidden dangers were enormous. Savage decoration demolition lightning line The reporter went to a residential area outside the East Sixth Ring Road in Beijing. The district has several 31-storey residential buildings nearly 100 meters high. Mr. Zhao’s home is located on the 21st floor. The reporter saw that there was a lightning protection line at the metal pipe of Mr. Zhao’s bathroom close to the radiator. Mr. Zhao told reporters that this lightning protection line connects the metal pipe of the radiator to the steel bar in the floor. When the building was repossessed, the developer told the owner that the lightning protection line could not be removed, otherwise there would be safety hazards. However, Mr. Zhao found that some of the neighbors upstairs and downstairs had already removed the lightning protection line during the renovation. "This is the thunderstorm season. It is troublesome to encounter lightning strikes." Mr. Zhao was somewhat uneasy about this. The reporter randomly visited more than 10 residents in the community, and more than half of the owners admitted to removing the lightning protection line. When it comes to the reasons, they generally said that the lightning protection line is not beautiful and hinders the decoration. The owners said that the original radiator was outdated and that new radiators had to be replaced during the renovation. Therefore, the lightning protection line and the heating were removed. They have not considered the security issues that may arise. Several owners said that lightning protection devices were installed at the top of the high-rise residential buildings, and there is no need to install lightning protection lines at home. In response to the problem of the owner dismantling the lightning protection line, a staff member of the residential property company told the reporter that many owners of the community have dismantled the lightning protection line, and the property has no right to forcefully stop it, which is very helpless. However, Mr. Zhao believes that the property has not fulfilled its supervisory obligations. Mr. Zhao provided the reporter with the “Property Management Agreement†and “Renovation Management Rules†of the community. These two documents must be signed and collected when each owner collects the building. It stipulates that all owners shall not arbitrarily move the original position of the heating during the decoration, and shall not arbitrarily dismantle all the pipelines. The owner must pay the deposit before the decoration. If there is any illegal decoration during the decoration process, the property can deduct the deposit and urge the owner to correct it. Obviously, these two regulations have become a dead letter. Indoor lightning protection line In fact, the function description of the lightning protection line is clearly stated in the "Commodity Housing Instruction Manual" issued by the developer to the owner. The "Commodity House Instructions for Use" is supervised by the relevant departments and is designed to give users a better understanding of the technical parameters and usage knowledge of various parts of the house, and to guide users to use and maintain the relevant equipment correctly and reasonably. The reporter saw that Article 9 of the User Manual of the Community stipulates that the house is equipped with lightning protection devices, and the lightning protection antenna and ground wire shall not be dismantled or intercepted. A lightning protection expert from an authoritative organization in Beijing told reporters that according to China’s mandatory regulations “Code for lightning protection design of buildingsâ€, residential buildings with a height of nearly 100 meters should be designed and constructed for lightning protection, and after the special inspection of lightning protection, residential buildings Can be delivered for use. Indoor lightning protection devices such as lightning protection lines are an indispensable part of the lightning protection system of the entire residential building. It is very dangerous for the residents to dismantle them privately. According to reports, this indoor lightning protection line is not as “excessive†as some residents imagined, and it mainly plays the role of “equal potential connectionâ€. According to the lightning protection expert, the lightning current hits the residential building, and an induced current is generated on the indoor metal pipe. The indoor lightning protection wire connects the heating pipe with the steel bar in the floor to release the induced current to the building. The inner steel bar reduces the potential difference between the indoor metal pipe and the steel bar in the building, which is beneficial to protect the personal and property safety of the indoor residents. Therefore, the unauthorized removal of indoor lightning protection lines by residents will greatly increase the possibility of being struck by lightning, and the safety risks will arise. "In fact, not only the metal pipes of the radiators, but also the natural gas pipes and water pipes of high-rise residential buildings, if they are metal pipes, lightning protection lines should be installed. For these lightning protection lines, residents cannot arbitrarily remove them." Experts said. According to the reporter's understanding, in order to protect the building's lightning protection devices, relevant regulations have been issued in various places. Article 8 of the "Administrative Measures for the Safety of Use of Buildings in Beijing" clearly requires that damage protection or unauthorized removal of lightning protection devices be prohibited. Li Hongyun, a lawyer at Beijing Zhongtang Law Firm, pointed out that privately dismantling lightning protection devices must not only bear certain civil liabilities, but also may be subject to administrative penalties such as detention. If a major accident occurs, it may also constitute a crime. Hao Lijun, a researcher at the Electromagnetic Radiation Protection Research Office of the Beijing Labor Protection Science Research Institute, told reporters that lightning is a relatively complicated natural phenomenon. With the increasing number of high-rise buildings in the city, China’s requirements for lightning protection devices for high-rise buildings are also coming. The more strict. Lightning protection devices are closely related to the safety of residents' personal and property. Residents should raise their awareness of consciously maintaining lightning protection devices as soon as possible. The annual inspection system has loopholes With the increase of high-rise buildings and the popularity of computer network systems, the frequency of lightning disasters has increased greatly and the losses have become more and more serious. In order to effectively prevent lightning strikes, Article 31 of the Meteorological Law stipulates that all levels of meteorological authorities shall strengthen the organization and management of lightning disaster prevention work, and shall annually install lightning with the relevant departments on buildings, structures and other facilities that may be subject to lightning strikes. The disaster protection device is tested. In addition, the installed lightning disaster prevention device shall comply with the "Lightning Protection Design Code for Buildings". The relevant regulations on defensive lightning disasters issued in Beijing and all over the country clearly require that the lightning protection devices of new buildings must be put into use after obtaining the completion acceptance certificate issued by the local meteorological authority. Moreover, the owner or user of the lightning protection device should do the routine maintenance work of the lightning protection device and test the performance of the lightning protection device every year. However, Mr. Zhao told reporters that since his stay in 2009, the lightning protection devices of high-rise residential buildings in the community have never been tested, and the performance of the lightning protection system of high-rise residential buildings is unknown. "High-rise buildings with property rights, such as units, institutions, enterprises and institutions, are relatively easy to handle. However, there is no relatively complete solution for how to implement the lightning protection devices for residents in high-rise residential buildings." A lightning protection expert said, “The high-rise residential buildings in the community involve many owners, and there are inspection fees. The owners’ committee is needed to coordinate the organization. However, many new residential communities have not yet established a owners’ committee. This is indeed a problem that needs to be solved. Beijing and even Beijing. The function of the lightning protection device of the high-rise residential buildings in the country is in urgent need of comprehensive re-examination, and the inspection results should be publicized to the residents of the community."
