What problems should be paid attention to when tearing down the wall?

Precautions for wall demolition 1. Before tearing down the wall, it should be reported to the property for approval:

Under normal circumstances, when the building is completed, the original design unit will leave a drawing 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. According to the drawings, the property management company can determine which walls can be demolished. Therefore, before the wall reconstruction, the owner must submit the construction drawings given by the designer to the property management company, and the construction can only begin after the property is approved.

Precautions for removing walls 2. Top beam cannot be removed:

Some owners feel that the beams on the top of the house affect the appearance when decorating, and plan to remove the protruding parts of these beams. In fact, the beam in the middle of the house must not be removed, because the beam supports the upper floor, and the removal or transformation will cause the upper floor to fall.

In addition, it should be noted that if some walls are connected by beams, only the ones below the beams can be removed when they are removed. For example, the wall between the bedroom and the study was demolished in this construction site, but there are beams on the wall, so you can't move here, otherwise there will be security risks. When the beam cannot be removed, the beam can be hidden with a ceiling without affecting the appearance.

Precautions for wall demolition 3. Don't tear down the wall connecting the balcony:

In order to improve the lighting of the room, some owners removed part of the wall connecting the balcony and increased the width of the balcony door, which is not allowed. Because the external walls of houses are generally load-bearing walls, it is very dangerous to make holes and open windows in them.

In addition, some rooms have a window and a door on the wall between balconies. These doors and windows can be removed, but the wall under the window cannot be removed. This wall on the window line is called "counterweight wall", which plays the role of provoking the balcony. If this wall is torn down, it will reduce the bearing capacity of the balcony and cause it to fall.

Precautions for wall demolition 4. It is forbidden to dismantle the load-bearing wall:

As many people know, the load-bearing wall can't be dismantled in the decoration. But what kind of wall is a load-bearing wall, not many people can say clearly. A load-bearing wall is a wall without precast ring beams. The wall thickness of load-bearing wall is obviously thicker than that of non-load-bearing wall in plan view. The actual wall thickness is generally 24 cm, and the non-bearing wall is 10 ~ 15 cm. Exterior walls are generally load-bearing walls, and so are the walls used by neighbors. Generally, non-load-bearing walls are in bathrooms, storage rooms, kitchens and aisles.

In a word, the structural safety of the house will be affected if the wall is accidentally removed after the house is rebuilt. If the owner carries out structural transformation of the house, he needs to check the structural design drawings of the building to see which are the load-bearing walls, and consult relevant professionals before construction.

Precautions for wall demolition 5. The repair work after tearing down the wall cannot be saved:

The fence was safely removed, but the later repair work can not be ignored. For example, when the original wall is demolished and a new wall is built with red bricks, braces should be set on the new wall. "Bracing" is the construction method of the joint between the old and new walls, that is, the new and old walls are pulled with steel bars to ensure the stability and seismic capacity of the walls.

In addition, a doorway is opened in the wall, and a reinforced concrete "beam" should be erected above the doorway to share the pressure of the wall above the doorway and avoid the pressure above the wall directly pressing on the door frame.
