Can the interior walls of high-rise buildings be removed? Is the thickness of high-rise wall the same?

The indoor wall of high-rise building is a part of the indoor structure of high-rise building. In the process of decoration, the layout design of the room may need to change some indoor walls, and then we must know which walls can be demolished and which walls cannot be demolished. For high-rise interior walls, can high-rise interior walls be demolished? Quanxin demolition leads everyone to understand.

Can the interior walls of high-rise buildings be removed?

Whether high-rise indoor walls can be demolished depends on the type of high-rise walls. If it is a load-bearing wall, it cannot be removed; If it is a partition wall, it can be removed. Details are as follows:

1. Partition wall

The partition wall is a spatially separated component, and it is a non-bearing wall. The partition wall has light specific gravity, high strength, moderate wall thickness, convenient installation and reusability. It is usually the same as an ordinary wall, from front to top. But unlike traditional walls, most partition walls can be disassembled and reassembled, that is, "partition walls" can be reused. However, it is recommended not to dismantle it easily. If it is to be demolished, it must be approved by the property department.

2. load-bearing wall

Load-bearing wall refers to the wall that supports the weight of the upper floor. It is the pillar of the building and an important part of indoor safety. Destroying the load-bearing wall is to destroy the seismic capacity of the building. Generally speaking, building structures are brick-concrete structures, and all walls are load-bearing walls. The outer wall of a frame structure building is a load-bearing wall, but the inner wall is generally not. Therefore, when removing and replacing high-rise indoor walls, we should also look at what the building structure is like, and then judge whether the walls can be removed.

Are the high walls the same thickness?

High-rise residence should be frame structure residence. Generally, the wall does not have load-bearing function, but the thickness of the wall of a single building should be consistent. Generally speaking, the inner and outer wall thickness of high-rise residential buildings with more than 10 floors is 200 mm, the inner and outer walls at the bottom are 250~300mm, and the inner and outer walls at the upper part are 200 mm and 30 floors. The bottom can reach 350 mm thick, the middle is slightly thinner, and the top can reach 200 mm, and the wall thickness will further increase. Therefore, the indoor wall thickness of high-rise buildings is generally the same, but the thickness will be different according to the number of floors.

Is it normal for cracks to appear in the wall of high-rise buildings?

Cracks in the walls of high-rise residential buildings, whether shear walls or infilled walls or cracks between two walls, are abnormal. This is due to mistakes in building construction. We should find the causes and solutions of cracks:

1. The external wall has insufficient compressive capacity.

Due to the insufficient compressive capacity of the external wall itself, cracks appear in the indoor wall. The solution is as follows: reinforce the perimeter of the building.

2. Insufficient bearing capacity of external walls

The actual bearing capacity of the external wall has exceeded the design bearing capacity. At this point, the solution is to drive dense piles around the building to stabilize the foundation.

3. The external wall foundation size is incorrect.

Poor durability or measurement error of the external wall "wall foundation" may also lead to wall cracking. The solution at this time is to pour concrete ring beams around the building.
