What is the thickness of the load-bearing wall of public buildings?

Traditionally, people call 370 mm thick wall "Sanqi Wall" and 240 mm thick wall "Si Er Wall". In engineering, walls with a thickness greater than or equal to 240 mm are often used as load-bearing walls, and walls with a thickness less than 240 mm are used as non-load-bearing walls.

Load-bearing walls are divided into vertical load-bearing walls and horizontal load-bearing walls, which bear the load on the upper part of the building and the seismic forces from vertical and horizontal directions respectively. As a load-bearing wall, the external wall should be paid full attention to. Non-load-bearing walls can only bear their own weight but not the upper load, so they can be used as partition walls.

In order to ensure the safety of its building structure in indoor decoration, we should attach great importance to and put an end to the hidden dangers that endanger the safety of residential structures caused by "tearing down walls and digging holes" in decoration.

Extended data:

Distinguish the bearing wall and non-bearing wall from the building structure;

Generally speaking, the walls of brick-concrete buildings are load-bearing walls; The walls in a general frame structure house are not load-bearing walls.

2. From the perspective of housing grade: ordinary middle and low-grade houses and villas are brick-concrete structures. High-end products are mostly frame structures.

3. Distinguish from the material of wall brick: the wall of general standard brick is a load-bearing wall, and the wall of aerated brick is a non-load-bearing wall.

4. According to the wall thickness, 150mm thick partition wall is a non-bearing wall, such as bathroom and kitchen.

5. According to the joint between the beam and the wall, the method of obliquely arranging bricks must be a non-bearing wall. The load-bearing wall can be closely combined between the wall and the beam;

6. Judging from the sound: knocking on the wall has a crisp big echo, which is a light wall, while the load-bearing wall should not have much sound.

7. Nine times out of ten, there are columns protruding from the corner or wall in the room, which are frame structures.
