1, load-bearing wall In the decoration, the load-bearing wall cannot be demolished. What kind of wall is the load-bearing wall? Generally, in the “brick-mixed†structure, all prefabricated panels cannot be removed or opened; more than 24 cm of brick wall is also a load-bearing The wall can't be changed. The walls that are knocked up with "empty sound" are mostly non-bearing walls that can be dismantled. Some engineering teams open the door and open the window on the load-bearing wall, which will also damage the weight of the wall and is not allowed. Before the construction, it should be reported to the property management department for record, and approved before construction. 2, bearing beam column These beams and columns are used to support the upper floor slab. After the detachment, the upper slab will fall down, which is very dangerous, so it is not free to dismantle and destroy. 3. Steel bars in the wall If the structure of the house is more than the body of an adult, the steel bars in the wall are the bones of the person. When you are in the slotting line, avoid the steel bars. It is best not to cross-cut. If the steel bars are damaged when the pipeline is buried, it will affect the bearing capacity of the wall and the floor. Such walls and slabs can easily collapse or break in the event of an earthquake. 4, the low wall next to the balcony There is a window between the room and the balcony. These doors and windows can be removed, but the walls below the window cannot move. This wall is called the “weight wall†and it acts like a scale to provoke a balcony. The wall was demolished, causing the load-bearing capacity of the balcony to drop, causing the balcony to fall, with unpredictable consequences. The door of the "three defenses" or "five defenses", the door frames of these household doors are embedded in the concrete, if the demolishing will damage the building structure and reduce the safety factor. And it destroyed the building structure of the doorway, and it was even more difficult to reinstall the new door. 5, waterproof layer of bathroom and kitchen In these places, there is a waterproof layer under the ground. If it is destroyed, it will become a "water curtain hole" downstairs. Therefore, when you replace the floor material, be careful not to damage the waterproof layer. If it is rebuilt after the damage, it must be re-waterproofed. After the "24-hour water seepage test", it will be qualified if it does not leak water.
