On the morning of November 15, the Wuhan Jianghan District Housing Management Bureau responded to Nandu reporters that it had dispatched a working group responsible for safety inspections Conduct a comprehensive investigation of the community involved.
While we mourn the victims of this accident, we have to think deeply about how to eradicate the outer wallespecially exterior wall tilesfalling off'sProblem. In the past few years, incidents of exterior wall bricks falling off have occurred frequently, from time to time 地 will be online span>ExposedSome news came out , it’s just not like this incident's
According to Xinhua News Agency,,This yearMarchShanghaialsooccurrenceover'sSociety'swidely concerned. Industry insiders believe that the continuous occurrence of housing safety incidents deserves reflection by relevant departments, and a long-term mechanism needs to be established to make up for the shortcomings of urban construction safety management.
This year June,ChongqingThe public interest litigation department of the Qijiang District Procuratorate received clues from the public that there are many old residential buildings in Qiji Community and other places. There are serious problems of hollowing and falling off of exterior wall tiles. In some places, residents and vehicles have been injured and damaged by falling tiles.
This year On the morning of August 22, Mr. Zhou, who lives in Changsha Fuji Century Park, called the People's Daily News hotlineReflect, Afternoon on the 21st , he discovered a large area of hollowing in the exterior wall of the house outside his balcony. The gap between the exterior wall bricks and the wall reached ten centimeters, and there was a risk of falling off at any time and injuring someone. Mr. Zhou told reporters that Building 80, Fuji Century Park, where he lives, was delivered at the end of 2018 , it has been less than three years. Also in Changsha, residents of Jinfu Xingyuehui Community in Wangcheng District, Changsha discovered that a large piece of exterior wall tiles of a residential building fell from a height and shattered to the ground. The community was delivered in 2019, and the owners started moving in last year. After moving in for just over a year, this is not the first time a similar problem of exterior walls falling off has occurred.
This year On October 10, Mr. Huang, the owner of a community in Fuzhou, lost his car because the tiles on the exterior wall of the community fell off. Suffered a disaster. From 2018 to October 2021, there have been many incidents of exterior wall tiles falling off in Mr. Huang’s community. On October 27, Ms. Wang from Changsha drove to a party in the business district of Xingdian Times Community in Furong District. When she came out, she found that the rear window of her car had been smashed by a brick that fell from the sky.
Policy pressure, where is the way out for exterior wall bricks
In March, shortly after Xinhua News Agency reported the incident of exterior wall bricks falling off, the Shanghai Municipal Housing and Urban-Rural Development Commission and the Shanghai Municipal Housing Authority jointly issued a The "Notice on Further Strengthening the Investigation and Rectification of Hidden Hazards from Falling Houses" further strengthens the investigation and rectification of hidden dangers from falling houses to ensure the safety of people's lives and property. As of 2021On April 23, a total of 25,980 buildings in Shanghai were inspected, and there were 7,055 hidden dangers such as cracks, hollowing, and falling off of exterior walls; 4,722 hidden dangers such as cracking, deformation, and loosening of building attachments; and wall attachments. There are 15,294 hidden dangers of deformation, corrosion, and shedding.
But once the exterior wall tilesFalling off can easily cause casualties, especially falling off from a height of more than 10 floors. Once it falls on a person, death is foreseeable on the spot. It is precisely because of the high accident rate and great harm caused by tile falling off that the Ministry of Housing and Urban-Rural Development< span style="font-family:宋体">InJuly发文
It is precisely because of the exterior wall tiles in recent years"Height Limit Order" PolicyRestrictions, Sichuan's exterior wall brick output continued to decline. In 2020, there are 10 exterior wall tile manufacturers and 14 exterior wall tile production lines in Sichuan production areas, with a total daily production capacity of more than 200,000 square meters,Now, the number of exterior wall brick manufacturers has almost halved, and companies may suspend kilns for a long time or change their production to other industries. He Products . According to senior industry insiders, a Sichuan exterior wall tile company's monthly sales exceeded 20 million yuan at its peak, but now its monthly sales are only a few million yuan ,Moreover, no exterior wall tile company in Sichuan can produce at full capacity.< /span>
The exterior wall fell off, and the exterior wall bricks took the blame
Although incidents of exterior wall falling off occur one after another,resultConsumers are deeply resentful of exterior wall tiles. But carefullyThinking, exterior wall Brick is largely responsible for the quality of construction in the past 10 years. There are three main reasons:< /span>
First, exterior wall bricks< strong>has natural disadvantages . Ceramic tiles because of themselvesWeightProblems with construction technology, objectively there is indeed a risk of falling off.No matter how small the possibility of this risk is,ButIf in our countryBased on the huge number of buildings, which means that the exterior wall tiles have fallen offis a large area . Ceramic tiles are used as falling objects from high altitude,Free fall and self-weight are superimposed,< span style="font-family:宋体">Once an accident occurs, misfortune is bound to happen, just like the result of the Wuhan accident. This kind of hurtful incident that happens from time to time makes consumers magnify the incident itself. At the same time, the setting of "possible falling off" is also imprinted on people's psychology了negative points. Therefore, this is a natural disadvantage of exterior wall tiles.
Second, external wall falling off is bound to happen, but the accident rate should not be so high. The reason why the exterior wall bricks fell off emerge in endlessly because of the quality of the project. There are two construction techniques for exterior wall tiles: wet Hanging and dry hanging. Dry hanging can only reduce, but cannot completely avoid, the risk of falling off. However, in the early days, dry hanging was not fully promoted due to the high process requirements; now, due to cost issues, dry hanging has increased the cost of exterior walls< /span>,< /span> was not promoted originally. There is a risk of detachment, and developers may not build according to construction standards, so detachment incidents occur one after another. Just like the two cases in Changsha mentioned above, cracks have already appeared before the delivery of the property has passed the warranty period. It is difficult for people to believe that the developer is building. It is reasonable to work carefully when carrying out engineering work to ensure the quality of the project. "Tofu" projects increase the risk of tiles falling off. >
Third, no one is responsible for the falling off incident. Looking at the past, when tiles fall off, it is a big problem who will bear the loss afterwards. For example, as mentioned aboveFuzhou incident on October 10th, if 70 people in the community are affected The whole building needs to be repaired, which requires 5 million yuan of funds; the compensation request for the party Mr. Hu cannot be completed in full.
Another example "The exterior wall of a residential building in Changsha fell off many times and injured people, so that the owner did not dare to take a walk." In one incident, the property management company that managed the community just made a red warning sign and posted it in a prominent location, reminding owners and vehicles to "keep away from the wall, be careful of falling tiles, and ask for high-altitude workers to come and deal with it" span>, in addition to < /span>No other measures span>The property company stated , "On the one hand, we are short of funds and cannot satisfy the owners' demands of knocking out all the walls and renovating them; on the other hand, the developers are actually responsible for housing problems, and we have done what we can.Nothing can be done. "In order to solve the problem of falling wall tiles, the owners have sought help from many parties,"We went to the district Housing and Urban-Rural Development Bureau, and they said it was built by the Municipal Housing and Urban-Rural Development Bureau. After going to the Municipal Housing and Urban-Rural Development Bureau, they asked us to go to the Municipal Supervision and Management Station. Finally, we got a reply and said that the 5-year warranty period had expired. The developer, Renyi Real Estate Co., Ltd., was deregistered in 2016 and cannot be contacted. "
......
The falling off of exterior wall bricks is in a sense paying for the substandard quality of the project. If it is built strictly in accordance with construction standards, the possibility of the exterior wall bricks falling off is actuallyVery low. But to this day, due to the inherent shortcomings of the craftsmanship andthe dragging down of "tofu dregs", exterior wall tiles have become increasingly difficult to use. ="font-family:宋体">has been pushed to the forefront of public opinion time and time again. If there are no new revolutionary changes in exterior wall tiles to overcome their inherent shortcomings, their market share will be replaced by coatings only after the "Catalogue of Construction Techniques, Equipment and Materials for Elimination of Housing Construction and Municipal Infrastructure Projects Endangering Production Safety" is officially promulgated and implemented. .
