Today let's talk about some common sense of the identification and testing of closed dilapidated houses:
Red River State Housing Inspection 00015388846862+++
A house is made up of many structural components, and it is incomplete to say that the house is in danger if there is a crack or tilt in one of the components. A dilapidated house is a house where the structure has been seriously damaged or the load-bearing components have become dangerous components, which may lose stability and bearing capacity at any time, and cannot guarantee the safety of living and use. The identification of the risk of the house shall be carried out according to the structural characteristics of the identified house and the type of load-bearing system, according to its degree of danger and scope of influence, and according to the risk identification standard of the house. Dilapidated houses are identified by building and measured according to the construction area. The house is composed of three components: the foundation, the upper load-bearing structure and the envelope.
The main reasons for the formation of dangerous houses include the following: exceeding the specified service life of the house; The house is in disrepair and badly damaged; The main structure of the house is demolished and altered at will, such as: digging holes in the load-bearing wall to open doors and windows, removing the wall between the balcony and the room to expand the size of the doors and windows, demolishing and modifying the kitchen and bathroom walls, building and sealing the balcony with heavy materials such as bricks or concrete, and erecting hanging balconies with angle steel and other materials outside the wall; Improper foundation treatment when building a new house causes uneven settlement of adjacent houses; Fires, floods, subsidence and vandalism.
There are more damage and large deformation in the house, and it is recommended to carry out structural overhaul of the house, and the specific treatment suggestions are as follows:
1) For the penetrating cracks of the wall, it is recommended to carry out pressure grouting first, and then use the double-sided outer reinforcement mortar surface layer to reinforce.
2) For the walls that have formed dangerous points and the walls with large inclination, it is recommended to partially dismantle and re-masonry.
3) In view of the serious water seepage on the roof of the house and the decay and splitting of the wooden purlins, wooden rafters and wooden roof trusses, it is recommended to renovate the entire roof, replace the damaged wooden components, and re-lay the waterproof layer.
4) For the overall deformation of the house, it is recommended to take foundation reinforcement treatment.
5) For the case of water leakage on the wall, effective measures should be taken to deal with the cause of leakage.
6) Reinforcement and repair should be designed and constructed by a design and construction unit with corresponding qualifications.
Therefore, it is necessary to inspect the house regularly, especially during the storm and thunderstorm season. When problems are discovered, measures should be taken to deal with them in a timely manner, just as people should see a doctor in time and prescribe the right medicine after they are sick. This can not only prolong the service life of the house, but more importantly, avoid the occurrence of house safety accidents. Under normal conditions of construction and use, the house is able to meet the requirements of various intended functions within the specified number of years.
