"Several halls": refers to the living room and dining room. Generally speaking, three rooms and two halls are three rooms plus living room and dining room.
Load-bearing walls can be distinguished by floor plan, observing the building structure or knocking on the wall to listen to the sound, as follows:
1. Look at the floor plan data: In the floor plan of a house, the walls marked in black on the engineering drawing are all load-bearing walls, and the walls marked in white are non-load-bearing walls. This kind of wall can be rebuilt and demolished without affecting the construction.
2. Look at the structure of the house: Generally speaking, all the walls of a brick-concrete house are load-bearing walls. The outer wall of a house with frame structure is a load-bearing wall, but the inner wall is generally not.
3, look at the grade of the house: usually low-rise houses, bungalows, villas are brick-concrete structures, and the fundamentals are load-bearing walls. Both the high-rise elevator building and the foreign building are frame structures.
4. Look at the wall thickness: the non-bearing wall is relatively thin, generally about 10 cm thick. Pat it with your hand. It is a light wall with a crisp echo, and the thickness of the load-bearing wall is generally above 240MM, so there should be no too much noise when it is tilted.

Importance of load-bearing wall:
In the house, 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.
If the load-bearing wall is to be rebuilt, the owner must report to the property for approval, and the qualified design unit will give the reconstruction and reinforcement plan before the load-bearing wall of the house can be demolished. Moreover, the removal of the load-bearing wall must be done by a formal and qualified decoration company.
