Can you cut off a third of the load-bearing wall? How to remove the load-bearing wall?

After many owners buy a house, some people will change the wall of the house because they don't conform to the structure of the house or want to create more space. But when facing the load-bearing wall, if the changes to the wall are unreasonable, it will affect the structure and safety of the house. Can a third of the load-bearing wall be built? Next, Bian Xiao will give you a detailed introduction.

First, can I pay one-third of the load-bearing wall?

The load-bearing wall is not allowed to move at will, because it supports the weight of the whole building, and its thickness is determined according to the local seismic fortification intensity and building height. If the wall is knocked out or hollowed out, the structure of the whole building will be seriously damaged, which will have a great impact on all owners of the building. It is recommended to find the property to understand the situation before construction, and it is strictly forbidden to start demolition and reconstruction without permission.

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. Generally, in a building with brick-concrete structure, all prefabricated walls can't be removed. Brick walls over 24 cm are also load-bearing walls and cannot be demolished. Most of the walls with "empty sound" are non-bearing walls and can be demolished and changed.

In addition, it is not allowed for someone to open the door and open the window on the load-bearing wall, which will also damage the load-bearing of the wall. If you want to remove and replace the walls in your home during renovation, you'd better ask a building professional to have a look and determine whether it is a load-bearing wall before construction. Before construction, it must be reported to the property management department for the record, and construction can only be started after approval.

Can the load-bearing wall open the door Explanation 1:

If we put aside the legal constraints and only consider the technical level, the load-bearing wall can of course open the door. The key is to reinforce and add a door beam above the doorway in advance before the doorway is demolished, so that the weight borne by the original doorway is borne by the walls on both sides of the doorway. Ensure the stability of the structure. The height and width of the load-bearing wall need to be increased according to the use requirements, and the reinforcement methods adopted according to the size of the door opening are also different. Generally, small doorways are reinforced with carbon fiber or bonded steel. These two methods have the advantages of fast construction speed and light weight, and do not need to increase the section size, but they are only suitable for the load-bearing walls of concrete structures.

Can the load-bearing wall open the door

If the general residence is not a frame structure, the bathroom will be provided with additional ring beams, that is to say, only the floor of the bathroom in such a residence is concrete, and all openings will not damage the ring beams. In addition, channel steel must be embedded during construction, and the width of the door should not be too large.

Can the load-bearing wall open the door

To be on the safe side, you can ask the design unit of the building to calculate the bearing coefficient of the load-bearing wall and see if it can be modified. With a clear plan, there will be no big impact when starting work. The reinforcement scheme and demolition work must be completed by a professional decoration company with corresponding qualifications and must be approved by the property. Of course, it is generally not recommended that people in the industry take the initiative to use the load-bearing wall, because once neighbors find it, they have the right to sue and demand the restoration of the load-bearing wall.

The above is about whether the load-bearing wall can be pulled out by one third and whether the load-bearing wall can open the door.
