1. Bearing wall
What kind of wall is a load-bearing wall? In a building with a brick-concrete structure, any prefabricated slab wall cannot be dismantled or open doors and windows; brick walls over 24 cm in length are also load-bearing walls. In addition, some people open doors and windows on the load-bearing wall, which will also damage the load-bearing of the wall, which is also not allowed.
2. Reinforcement in the wall
If you compare the structure of a house to the body of an adult, the reinforcement in the wall is the human bone. If the steel bar is destroyed when the pipeline is buried, it will affect the bearing capacity of the wall and floor. In the event of an earthquake, such walls and floors can easily collapse or break.
3. Beams and columns in the room
These beams and columns are used to support the upper floor slab, and the upper floor slab will fall off after being removed, so it cannot be moved.
4. Low wall by the balcony
Generally, there is a door and a window on the wall between the room and the balcony. These doors and windows can be removed and modified, but the wall below the window cannot be moved. This section of the wall is called the "counterweight wall" and it acts like a scale to provoke a balcony. Dismantling this wall will reduce the load-bearing capacity of the balcony and cause the balcony to fall.
5. "Three defense" or "five defense" door
The door frames of these doors are embedded in concrete. If they are demolished, they will destroy the building structure and reduce the safety factor. Moreover, the building structure at the door was destroyed, and it was more difficult to reinstall the new door.
6. Bathroom and kitchen
There is a waterproof layer on the ground in these places. If it is damaged, the downstairs will become a "water curtain hole." When you change the ground material, be sure not to damage the waterproof layer. If you rebuild after the damage, you must do " "24-hour water seepage test", that is, irrigating in the kitchen or bathroom, if it does not leak after 24 hours, it is considered qualified.
