Who will repair the peeling of the outer wall of the old building?

Abstract: In recent years, the external walls of high-rise buildings are damaged, and incidents of injuries caused by falling tiles and cement blocks from the external walls of high-rise buildings are frequently seen in the media. For example, in June 5438+ 10, 2002, a cement block suddenly fell from the third floor of Yihai Building at the intersection of Rouge Road and Liangdao Street in Wuchang, knocking a passing mother and daughter to the ground and seriously injuring her daughter. So how to avoid the brick falling off when decorating the exterior wall of high-rise building? Who will repair the peeling of the outer wall of the old building, and how to avoid the injury accident of the outer wall?

The residential buildings located in Licheng Street, Chengfeng Road and Fupeng Market of Kaiyuan Road, after more than ten years of "baptism", the external walls of the buildings began to peel off in a large area, which has many security risks. Because there is no property management and owners' committee, the external wall maintenance of these buildings has not been properly solved. So who is responsible for the maintenance of the external walls of these old buildings?

One of the reasons for the peeling of the outer wall of the old building: early contractors built it with yellow mud.

When it's windy and rainy, Mr. Cao, who lives near the Fu Peng market, is particularly nervous, because when waiting for the bus on the roadside, he needs to pay special attention to the "stone shit" airborne on the outer wall of the old residential building next to him. The reporter visited the Fu Peng market yesterday and found that many old residential buildings were peeling. Only four external walls of the old residential buildings from No.2 Chengfeng Road to 10 have fallen off. On the external walls of these old residential buildings, the largest peeling area is nearly 1 square meter. "The external walls of these old buildings are peeling off. In addition to the long age, there is another reason that the early contractors used yellow mud to build external walls." An industry insider Mr. Li said.

"The problem of peeling off the external walls of old buildings has long attracted the attention of neighborhood committees and residents. Previously, the "stone excrement" of a building peeled off, hurting the arms of passers-by. However, after waiting for several months, no one has come to repair it. Now only scaffolding is used to enclose the peeling part of the outer wall of the building. " Under the guidance of Miss Chen, the reporter came to this old residential building located in the third lane of Kaiyuan East Road. The whole building is surrounded by scaffolding except the entrance and exit, and warning signs of "Do not approach the peeling wall" are hung in many places on the lower part of the external wall. The reporter looked up and saw that the outer wall burst in many places, showing deep cracks, and the "stone excrement" attached around it was crumbling.

All owners of old buildings have the obligation to maintain the external walls.

In view of the question of who will repair the peeling of the external wall of the old building, lawyer Luo Xueyuan of Zengtai Law Firm said that according to Articles 6 and 7 of the Measures for Quality Warranty of Housing Construction Projects, the construction unit and the construction unit should stipulate the warranty scope, warranty period and warranty responsibility in the project quality warranty, and the warranty scope and warranty period agreed by both parties must comply with relevant state regulations. Under normal use, the minimum warranty period of housing construction project is: (1) foundation project and main structure project, which is the reasonable service life of the project specified in the design document; (2) Roof waterproofing works, the leakage prevention of bathrooms, rooms and external walls with waterproof requirements, is 5 years; (3) The heating and cooling system consists of two heating periods and cooling periods; (4) Installation of electrical pipelines, water supply and drainage pipelines and equipment for 2 years; (5) The renovation project lasts for 2 years. Therefore, according to the document, the old building built in the 1990s is so old that the developer has no obligation to undertake the warranty responsibility for the owner, and the owner should undertake the maintenance obligation by himself according to law.

Lawyer Luo said that at present, the owners of newly developed houses need to pay a special fund for housing maintenance, which is used exclusively for housing maintenance. The external wall of the building is shared by all the owners of the building. If all owners are unwilling to undertake maintenance obligations, or some owners do not agree to pay, the proposal for external wall maintenance cannot be passed. Once the external wall falls off and hurts people, all owners shall be jointly and severally liable for compensation.

Maintenance costs are huge and difficult to raise.

It is understood that the old buildings with peeling external walls are mainly early developed commercial houses and self-built houses, most of which have been built for more than ten years. The above-mentioned old residential building in Lane 3 of Kaiyuan East Road belongs to the self-built building of the unit. According to the owner of the building, the maintenance notice of the external wall of the building was received during the Asian Games, and the maintenance cost was finally 6.5438+0.3 million yuan/household. "We really want to maintain it, and we also know that peeling off the external wall will not only bring security risks to others, but also be dangerous to get in and out by ourselves." Ms. Li, the owner, said, "But the maintenance cost is too high. A household will cost more than 10,000, which is simply unbearable. "

A clerk of Kaiyuan Neighborhood Committee told the reporter that most of the owners of the old buildings built by such units are not employees of the units, and there is no property management and owners' committee. Therefore, in the face of huge maintenance costs, it is a very arduous task to gather these households to negotiate and share the costs equally.

In recent years, the external walls of high-rise buildings have been damaged, and incidents of ceramic tiles and cement blocks falling off the external walls of high-rise buildings have frequently been seen in the media. For example, in June 5438+ 10, 2002, a cement block suddenly fell from the third floor of Yihai Building at the intersection of Rouge Road and Liangdao Street in Wuchang, knocking a passing mother and daughter to the ground and seriously injuring her daughter. In April of the same year, a Lexus parked in the parking lot of a hospital in Xinhua Road, Hankou suddenly encountered unexpected troubles. A tile falling from the air smashed the glass and hood. At 6 o'clock in the evening on September 15 this year, a man in his fifties was killed when he was pushing his bicycle from the First Avenue of Hanzheng Street.

The staff of a construction engineering quality supervision station said that the external wall of a high-rise building fell off, which was mainly caused by the comprehensive effect of external factors. Temperature difference, humidity, vibration caused by artificial decoration, etc. , will make the bonding surface of the external wall loose or fall off. As long as the house is maintained in time, the above hidden dangers can be avoided. As a property unit, houses should be inspected regularly to eliminate hidden dangers in time. If residents find hidden dangers in their houses, they can report them to relevant departments.

Ceramic tiles: how to avoid falling off?

Clean the base surface before tiling.

If there are decorations such as lime putty, latex paint and wallpaper on the wall, or there is dirt on the ground, it must be cleaned up, otherwise the cement mortar will not be firmly bonded to the base; In addition, if there are cracks in the wall itself, proper treatment should be done before sticking bricks to avoid cracking or falling off of wall bricks caused by the expansion of cracks in the grass-roots structure in the future; Also, for the ground and wall with too big difference in flatness or verticality, cement mortar should be used for leveling; Compare the color difference of tiles before laying.

Wall tiles should be fully soaked.

Because of the high moisture content of wall tiles, this characteristic must be considered when pasting; Before tiling, the base should be fully watered and moistened, otherwise the moisture in the mortar will be quickly absorbed by the dry base and ceramic tile, which will affect its bonding fastness; Otherwise, the wall brick will absorb water from the cement, so that the cement can not play the role of adhesive.

First of all, floor tiles should be laid.

Cement-free floor tiles shall be laid on the ground, and cement floor tiles shall be laid after being leveled, and the diagonal positions of the four tiles shall be flush; The laying order is also particular; Bricks stuck to the ground should be stuck from the inside out. If there is a slope or floor drain on the ground, pay attention to find the slope according to the drainage direction; The wall brick should be laid from bottom to top, and for the sake of beauty, the bottom brick should be attached afterwards; After the wall tiles are pasted, press the floor tiles; In addition, one wall can't be glued to the top at a time, in case the tiles collapse due to self-weight; Don't trample on the floor tiles for a short time after laying.

Soak as many tiles as possible.

In summer, because the materials are drier than usual, it is necessary to extend the soaking time for materials such as floor tiles and tiles that need to be soaked in water to make their water close to saturation; In this way, there will be no phenomenon that the cement absorbs water due to dryness when ceramic tiles are bonded, so that they are not firmly bonded with cement, and there will be empty drums and falls off, which will bring you some unnecessary troubles;

In order to cater to fashionable consumers, some new technological methods have appeared in the market, such as tile adhesive, color caulking agent, seam leaving and paving. Ceramic tile binder (also known as dry bonding method), ceramic tiles do not need to be soaked in water in advance, and the base surface does not need to be wet. As long as the basic conditions of paving are good, the working conditions are greatly improved.
