Home shock: what can not be touched in the home improvement
In the renovation, breaking off the bearing wall is a dangerous practice. Especially in the case of an earthquake, the disadvantages are easily exposed. According to industry experts, under normal circumstances, if a household on the first floor removes a large area of ​​the bearing wall, this will cause the seismic performance of the building to weaken and the load stress to be abnormal. If an earthquake of magnitude 8 occurs at this time, the building is likely to occur. The whole collapsed. In addition, it is not the most important load-bearing wall on the first floor, and the importance of other floors is decreasing. Even if the load-bearing walls on the first floor are not demolished, and the load-bearing walls on other floors are dismantled, the stress structure of the building will be deformed, the structure will become more fragile, and the possibility of catastrophic collapse will remain great.
1, bearing wall
What kind of wall is a load-bearing wall? In a building with a typical brick-concrete structure, all prefabricated walls cannot be dismantled or doors open; windows that exceed 24 cm or more are also load-bearing walls. In addition, some people open the window on the load-bearing wall, which also undermines the weight of the wall. It is also not allowed.
2. Reinforcement in the wall
If the structure of the house is likened to the body of an adult, the steel bars in the wall are the bones of human beings. If the reinforcement is damaged when the pipeline is laid, it will affect the bearing capacity of the wall and the floor. In the event of an earthquake, such walls and floors can easily collapse or break.
3, beams in the room
These pillars are used to support the upper floor slabs. After the upper floors are removed, they will fall, so they cannot move.
4. The low wall of the balcony
There is a window on the wall between the general room and the balcony. The doors and windows can be changed, but the walls below the window cannot be moved. This wall is called the weight wall. It acts like a scale to lift the balcony. Demolition of this wall will reduce the bearing capacity of the balcony and cause the balcony to fall.
5, three or five anti-doors
The door frames of these doors are embedded in concrete. If they are demolished, they will damage the building structure and reduce the safety factor. It also destroyed the building structure at the entrance and it was even more difficult to reinstall the new door.
6, bathroom and kitchen
There is a waterproof layer on the ground of these places. If it is destroyed, the downstairs will become a water curtain hole. Therefore, be careful not to damage the waterproof layer when you replace the floor material. If the damage is reconstructed, a 24-hour water seepage test must be performed, that is, water is poured in the kitchen or bathroom, and if it does not leak after 24 hours, it will be qualified.
