Recently, a high-altitude falling object occurred near Longchi Community, Jiaomei Town, Zhangzhou, Fujian Province, and a young child was smashed and sent to the hospital, unfortunately killed, and died in the hospital at about 17 o'clock on the same day. According to preliminary investigations, the complex was completed in 2014 and the deceased was struck downstairs by a plastering layer that had fallen off the decorative pillars of a high-rise exterior balcony. 
The tragedy was mainly caused by the falling off of the exterior walls of high-rise buildings, which are by no means trivial matters, and this kind of "aerial bomb" seriously threatens the safety of the public's lives and property.
According to the analysis of many industry insiders, many buildings are old or the quality of the exterior walls of the buildings is not up to standard, and the exterior walls will gradually become "fragile" due to the sun and rain for a long time, with chalking, cracking, falling off and hollowing. The main reasons for the bulging and falling off of the exterior wall are four aspects: disrepair, material quality problems and hidden dangers, process standardization problems, external wall leakage and poor waterproofing.
Usually after 10 years of old buildings, the lack of regular daily monitoring and maintenance will lead to the accumulation of hidden dangers such as exterior wall structure and plastering, from cracking and hollowing to peeling and peeling.
Insufficient or substandard quality of building materials used for plastering, coating or tile pasting on exterior walls is also a risk of quality hazards. Especially after a certain number of years, the risks and hidden dangers will be exposed, resulting in quality defects in the whole or part of the building.
Building standard materials also need to strictly implement the process specifications and construction, non-standard process or beyond the process specification of construction, is often an important reason for the quality of the exterior wall.
Due to the structural reasons of the external wall of the building or the external stress factors, the local external wall (such as the parapet wall, window, external balcony, etc.) due to cracking, poor waterproofing and leakage, perennial damp water erosion, and then superimposed expansion and contraction stress and other problems, often resulting in local hollowing, layering. If it is not discovered, treated and repaired in time, the accumulation of sun and moon will eventually lead to the hidden danger of falling off.
In recent years, the number of high-rise buildings has increased, the age of the building has increased, and the reports of high-altitude falling object accidents caused by the falling off of the decorative surface and hanging objects of the external wall of the building have been reported from time to time, and it is not uncommon to smash cars and injure people, which greatly threatens the public safety of the city and arouses widespread concern in the society. This kind of "catastrophe from heaven" is embarrassing at the same time, but also makes people think deeply, how to solve such "old and difficult" problems and hold up a "safety umbrella" for residents
Strengthening the physical examination of buildings and preventing them from happening has become one of the main ways to crack the falling off of external walls. Carry out regular professional inspection of existing buildings, introduce intelligent non-destructive testing methods, carry out accurate detection and analysis of old buildings, risk early warning, timely detection of problems, and cooperate with the use of professional technology and product system to provide "optimal solutions" for the repair of old buildings, eliminate potential safety hazards, and avoid aggravation of "disease".
Building façade reinforcement is the first step in creating a safe environment. For problems such as cracking, hollowing, water seepage, and external wall falling off the external wall of the building, the safety and stability of the building wall are ensured through reinforcement and repair, and the comprehensive repair is mainly carried out without demolition, supplemented by a small amount of demolition and comprehensive repair, so as to extend the overall service life of the building and protect the life and property safety of the people around the building.
In response to the general trend of the building stock market, in response to the four major pain points of China's building repair industry, Guke Tianhe system has been innovatively developed to integrate detection system, product system and technical system, which covers building detection system, in-situ reinforcement system, waterproof and leakage plugging system, and Tianhe plate system. With the strong advantages of comprehensive professionalism, demolition-free economy, energy saving and safety, it is committed to the continuous maintenance of the whole life cycle of buildings, value-added integrated services, to meet the needs of the people for safe and livable living, and to accelerate the high-quality development of China's building repair industry.
There is a long way to go to guard the city's high-altitude safety, and it is particularly important to establish an existing building safety management mechanism
