How to refute that the property does not allow the demolition of non-bearing walls?

If the owner of the non-load-bearing wall can knock it off, first go to the developer for the record, get their support and understanding, and pay attention to safety during construction. The garbage generated during decoration will affect the environment and should be cleaned up in time. The property only provides services for the owners, and has no decision-making power or approval power; However, in order to prevent accidents, the developer will entrust the property owner to supervise the renovation. In order to reduce the management pressure, the property owners hope to change places as little as possible.

How to judge load-bearing wall and non-load-bearing wall?

1. From the plan view: In general, the black bold solid line marked on the plan view indicates that the wall is a load-bearing wall, and the black hollow line or black thin solid line indicates a non-load-bearing wall. The specific situation shall be subject to the floor plan.

2. From the wall thickness: the thickness of non-load-bearing wall is relatively thin, usually only about 12 cm, while the wall of load-bearing wall is generally thick, at least above 24 cm. Users can judge whether it is a load-bearing wall by measuring the thickness of the wall.

3. From the perspective of structural types: there are many structural types of houses. If it is a brick-concrete house, all the walls are load-bearing walls. If it is a frame structure, generally only the outdoor walls are load-bearing walls, and the others are non-load-bearing walls, depending on the actual situation.

4. Judging from the knocking sound: Because the load-bearing walls are generally thick and are all solid bricks, you can tap the wall gently with a small hammer when judging. If the sound is crisp and echoes, it means that the wall is non-load-bearing. If the sound is dull, it means that this wall is probably a load-bearing wall. This method is difficult for non-professionals, so it is suggested to knock on several walls for comparison.

Precautions for safe wall removal:

1, the 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.

2. 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 the 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.

3. It is forbidden to dismantle the 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.

4. 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. Support 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, dig a door hole in the wall, and erect a reinforced concrete beam above the door hole to share the pressure of the wall above the door hole and avoid the pressure above the wall directly pressing on the door frame.

5. 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 decorating the wall, the owner must submit the construction drawings given by the designer to the property management company, and the construction can only be started after the property is recognized.
