When we were decorating, we were very concerned about the layout of the whole home and the distribution ratio of all the space in the whole area. For example, some people disliked the small size of the living room and wanted to open the living room and the restaurant to become a whole. It will involve the removal of the wall surface. We all know that our wall is divided into a load-bearing wall and a non-bearing wall. If you accidentally change the load-bearing wall, you can be in trouble. Today, the home of the decoration will introduce it to everyone. The difference between load-bearing walls and non-bearing walls , as well as other small knowledge.
First, the difference between load-bearing wall and non-bearing wall
1. Listening to the sound, the easiest way to identify the load-bearing wall is to tap the wall with your hand. There is a light-weight wall (non-bearing wall) with a crisp echo, and the basic sound of the hitting wall is a rather dull sound.
2, look at the thickness: Generally speaking, the load-bearing walls are relatively thick, and the 150mm-thick partition wall is a non-bearing wall.
3. Discrimination: The external wall and the wall shared with the neighbors are load-bearing walls. It is very dangerous to smash holes in such walls. Xiaobian reminds everyone here, don't dismantle the load-bearing walls. Most of the partition walls in the bathroom, storage room, kitchen and aisle are non-bearing walls. However, some non-bearing walls are also not removable.
4. Housing structure: Generally speaking, all walls of brick-concrete structures are load-bearing walls; the walls inside the frame structure are generally not load-bearing walls.
5, the material of the wall brick: the wall of the general standard brick is the load-bearing wall, and the aerated brick is the non-bearing wall.
Second, what is the role of the load-bearing wall?
The load-bearing wall generally refers to the wall on which the slab, joist, girders, trusses or roof slabs are placed. It not only bears the live loads and static loads transmitted by the slabs, girders, trusses, etc. in the above layers, but also bears the above layers. The weight of the body, and pass these loads to the lower wall until the foundation of the foundation.
What is the role of the non-bearing wall?
Non-load-bearing walls generally include self-supporting and strong, partition walls, infill walls, curtain walls, and non-load-bearing walls. They must not only bear the weight of the wall, but also the non-load-bearing wall. In the event of an earthquake, these non-load bearing walls will withstand the seismic forces along with the load-bearing walls.
Fourth, whether it is a load-bearing wall or a non-bearing wall, we must be cautious in demolition
1. In fact, not all non-bearing walls can be arbitrarily removed. The so-called non-bearing wall refers to the house consisting of a column frame of reinforced concrete. The floor is supported by a horizontal array, the array is supported by columns, and the columns are supported by the foundation. This structure is usually visible in the interior of the column. Most of the walls between the columns are filled with hollow bricks or ordinary bricks, which are generally non-bearing walls.
2. In order to improve the lighting of the room, some owners remove the wall connecting the balcony and increase the width of the balcony door. This is not allowed. Because the outer walls of the house are usually load-bearing walls, even if you open a hole in the window, it is very dangerous.
3. Carry out the renovation of the living room. Do not arbitrarily pierce the wall on the load-bearing wall, remove the wall connecting the balcony and the door and window, and expand the size of the original door and window or build another door and window. This will cause partial cracks in the building and seriously affect the seismic capacity, thus shortening The service life of the building.
It turns out that everyone may know that the load-bearing wall can't be changed at will, but I don't know which walls are load-bearing walls. Then, through the above understanding, we will find that the non-bearing wall can't be changed at will. If we want to remove it, we must make it in advance. Know well, ask all the questions.
