You need to tear down the wall when decorating. What are the precautions for removing the wall?

1, report to the property for approval before tearing down the wall:

1) Usually, when the building is completed, the original design unit will leave a design for the property management company. The thickness and materials of various walls such as load-bearing walls and non-load-bearing walls are clearly marked on the drawings.

2) According to the design drawings, the property management company can determine the removable wall, and the owner needs to submit the construction drawings given by the designer to the property management company before the wall reconstruction, and the construction can only be started after approval.

2. The beam at the top of the building cannot be removed:

1) More owners think that the beam at the top of the house is not beautiful and choose to remove the protruding part of the beam. It should be noted that the beam in the middle of the house must not be removed, because the beam supports the upper floor slab, and the removal will cause the upper floor slab to fall, which is a potential safety hazard.

2) It should also be noted that some walls are connected with the upper beams, and only the lower beams can be removed when the walls are removed. If the beam cannot be removed, you can choose to use the ceiling to hide the beam, which is both practical and beautiful.

3. The repair work after tearing down the wall cannot be saved:

1) The repair work after the wall is safely removed cannot be ignored. For example, when the original wall is demolished and a new wall is built with red bricks, tie bars should be set on the new wall. Scissoring is the construction method of the joint between the old and new walls. The new and old walls are pulled with steel bars to ensure the stability and seismic capacity of the walls.

2) If there is a door opening in the wall, a reinforced concrete "cross beam" should be erected above the door opening. The purpose of this is to share the pressure on the wall above the door opening and avoid the pressure on the door frame directly.

4, balcony low wall can't open:

There is usually a door and a window between the room and the balcony. These doors and windows can be removed and replaced, but the wall under the window can't be moved. This wall is called a counterweight wall. If the counterweight wall is demolished, the bearing capacity of the balcony will be reduced, and the balcony will fall, with unpredictable consequences.

The door frame of the "three-proof" or "five-proof" door is embedded in concrete. If they are removed, it will destroy the building structure and reduce the safety factor. It will be more difficult to install new doors.

5. The load-bearing wall of the house cannot be removed:

The load-bearing wall can't be removed and changed during decoration. A load-bearing wall is a wall without precast ring beams. On the plan, the wall thickness of the bearing wall is thicker than that of the non-bearing wall, generally 24 cm thick, and the non-bearing wall is 10- 15 cm.

(1) Exterior walls are usually load-bearing walls, and the walls used by neighbors are also load-bearing walls.

② Non-bearing walls are generally located in bathrooms, storerooms, kitchens and aisles.

6, slotting line to avoid wall reinforcement:

The steel bars in the wall are like human bones and muscles. Therefore, when slotting and routing, steel bars should be avoided, and it is best not to cross-cut. If steel bars are damaged when laying pipelines, the bearing capacity of walls and floors will be affected.

7, bathroom and kitchen waterproof layer:

There are waterproof layers under the floors of the bathroom and kitchen. If the waterproof layer is damaged, it will easily seep downstairs. Therefore, the owner must be careful not to destroy the waterproof layer when replacing the floor material. If it is rebuilt after destruction, it is necessary to do waterproof work again. After 24 hours of water seepage experiment, it is confirmed that it is qualified if it is not leaking.
