Load-bearing wall refers to the wall supporting the weight of the upper floor, which is a black wall on the engineering drawing. If it is knocked out, it will destroy the whole building structure. Non-load-bearing wall refers to a wall that does not support the weight of the upper floor, but only separates one room from another. There is a hollow wall on the engineering drawing. Whether this wall has much influence on the building structure.
The thick solid line in the construction drawing and the wall under the non-bearing beam in the ring beam structure are the bearing walls. If there is no prefabricated ring beam on the wall, it must be a load-bearing wall. Non-bearing walls are generally marked with thin solid lines or dotted lines on drawings, and the material is light and simple. Non-load-bearing walls are generally thin and only serve as partition walls.
The floor slab is supported on structural members such as load-bearing walls and beams. In our home, the weight of the floor, the weight of the furniture and so on. , should pass through the floor to the bearing wall and structural beam, and then pass through the bearing wall and beam to the lower bearing wall or structural column, and then to the foundation. Forming the structural skeleton of the whole house, just like the skeleton of the human body, is an important part of determining the safety of the whole house.
