The purpose of the renovation is not only satisfied with the decoration of the room by many people, but more importantly, it is hoped that the existing room layout in the room will be improved through the renovation to increase its use. As a result, more and more of the existing housing structures were remodeled during the renovation, mainly manifested in the demolition and modification of non-bearing walls.
In our traditional concept, there has always been such a view that the load-bearing wall in the room cannot be removed, but the non-bearing wall can be removed. This is actually a major misunderstanding. In fact, not all non-load-bearing walls are free to demolition. The so-called non-load-bearing wall refers to a house made up of a column frame made of reinforced concrete. The floor is supported by a horizontal and vertical array. The array is supported by columns and the columns are supported by the foundation. This structure is usually visible inside the column. The wall between columns is mostly filled with hollow bricks or ordinary bricks, which are generally non-load-bearing walls.
Many people believe that non-load-bearing walls do not bear weight, but the actual situation is not the case. Because non-load-bearing walls are secondary load-bearing members in relation to the load-bearing walls, it is also an extremely important support for the load-bearing walls. It bears at least two parts of load, one part is the weight of the wall. In a six-story residential building, for example, the non-supporting walls in the ground floor houses bear the weight of the upper five walls; the other part is structurally speaking, the non-bearing walls are usually It is also a design earthquake wall. In other words, if an earthquake occurs, these non-load-bearing walls will bear seismic forces together with the bearing walls. Therefore, for a certain family, removing a non-load-bearing wall or making a hole in the wall is not a big problem, but if residents of the whole building are arbitrarily dismantling and changing the non-load-bearing walls, the anti-seismic force of the building will be greatly reduced.
For house decoration, you must not arbitrarily wear holes in the load-bearing walls, dismantle the walls connecting the balconies and doors and windows, and enlarge the size of the original doors or windows or build additional doors and windows. This practice will cause partial cracks in the buildings and severely affect the earthquake resistance, thus shortening the use of the buildings. life.
