Whether the wall is a load-bearing wall depends on whether the wall itself is load-bearing.
Walls can be divided into horizontal wall bearing, vertical wall bearing, vertical and horizontal wall mixed bearing and partial frame bearing. The cross wall load-bearing is mostly used in small space buildings. When the vertical wall bears the load, the upper load is borne by the vertical wall, that is, the floor slab and roof slab are supported on the vertical wall, and the horizontal wall is a non-load-bearing partition wall. The vertical and horizontal wall load-bearing is suitable for buildings that require flexible layout, such as exhibition halls. Part-frame load-bearing refers to the structure of a large room, the outer wall and inner columns are combined to form a semi-frame load-bearing wall or the bottom layer is frame load-bearing, the upper layer is load-bearing wall, and beams and columns are used to replace part of the load-bearing wall structure.
The thick solid line in the construction drawing and the wall under the non-load-bearing beam in the ring beam structure are both load-bearing walls.
On-site inspection of walls without precast ring beams must be load-bearing walls. Non-load-bearing walls are generally marked with thin solid lines or dashed lines on the drawings. They are walls made of light and simple materials. Non-load-bearing walls are generally thin and are only used as partition walls.
Generally speaking, all walls of brick-concrete houses are load-bearing walls; the internal walls of frame-structure houses are generally not load-bearing walls. Of course, specific to the house structure itself, to determine whether the wall is a load-bearing wall, you should carefully study the original building drawings and conduct actual site surveys to determine.
Individual decoration can be combined with the following points to simply distinguish between load-bearing walls and non-bearing walls:
1. Distinguish from the house structure:
Generally speaking, all walls of brick-concrete houses are load-bearing walls; the internal walls of frame-structure houses are generally not load-bearing walls.
2. In terms of housing grade: the general middle and low-end residential buildings and villas are of brick-concrete structure. The high-end ones have more frame structures.
3. Distinguish from the material of the wall bricks: the general standard brick wall is a load-bearing wall, and the aerated brick is a non-load-bearing wall.
4. From the thickness of the wall: 150mm thick partition walls are non-load-bearing walls, such as bathrooms and kitchens.
5. According to the junction of beam and wall: the method of oblique row of bricks must be non-bearing wall. The close connection between the wall and the beam may be the load-bearing wall; 6. Judging by sound: the wall is lightly echoed when the wall is hit, and the load-bearing wall should not have much sound.
