Many people are not satisfied with the pattern of new houses, so they must be demolished. The demolition of the main body involves the structural safety of the house, so it cannot be sloppy. Some walls can be demolished, and some walls must not be demolished, or your home may become a dilapidated house. Let's take a look at what can't be removed in the main demolition reform . Main body demolition and modification 1, waterproof layer There is a waterproof layer under the ground in 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 it is damaged and reconstructed, it must be re-waterproofed. After the "48-hour seepage test", if it does not leak, it will be considered qualified. Demolition of the main body 2, load-bearing wall What kind of wall is the bearing wall? Generally speaking, in a building with a "brick-and-blend" structure, as long as it is a prefabricated wall, it cannot be dismantled or a window is opened; a brick wall over 24 cm is a load-bearing wall and cannot be removed or modified. The walls that have been knocked "empty sound" are mostly non-load-bearing walls that can be demolished. Some unscrupulous engineering teams open their windows on the load-bearing walls, which will also damage the wall's load-bearing weights and pose potential safety hazards. Prior to construction, the property management department should also report to the record and be approved for construction. The main demolition reform 3 , the balcony side of the wall In general, there is a window between the room and the balcony. These doors or windows can be changed, but the low walls below the windows cannot be moved. This wall is called "weight wall" and it plays the role of provoking the balcony. The demolition of this wall has led to a decline in the bearing capacity of the balcony and the risk of the balcony falling, with unpredictable consequences. For "three defenses" or "five preventions" doors, the door frames of these doors are embedded in the concrete. If the demolition changes will destroy 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. Subject demolition 4 , light wall In addition to load-bearing walls, light walls are not detachable. Some light walls also carry part of the weight of the house. For example, the light wall below the crossbeam cannot be removed because it also carries part of the weight of the house. If it is torn down, it will destroy the structure of the house. Lightweight walls and hollow panels that are completely partition walls are detachable. This kind of wall does not bear any pressure at all. The value of existence is to separate the space. The demolition will not cause any impact on the structure of the house. Demolition of the main body 5 , beams and columns Beams in the room cannot be changed. Beams and columns are used to support the upper floors. Demolition or renovation will cause the upper floors to fall down. It is very dangerous, so the columns and columns must not be demolished or modified. The steel bars in the wall cannot move. When the pipeline is laid, if the steel is damaged, it will affect the bearing capacity of the wall and the floor. Main body demolition reform 6, steel In the groove alignment, to avoid steel, it is best not to cross cut, if the destruction of steel bars in the pipeline, will affect the wall and floor bearing capacity. In the event of an earthquake, such walls and floors can easily collapse or break. The above is about the introduction of the demolition of the main body . I hope I can help you.
