At the moment, many homeowners are excessively pursuing the use and comfort of space while decorating their new homes. They are arbitrarily smashing the wall and daring to renovate the doors and windows. This site reminds owners that while pursuing beauty and comfort, home improvement should not ignore safety hazards.
"Sledgehammer" need to be careful when demolition
At present, there are three types of residential structures: full frame, half frame, and brick structure. The walls are divided into load-bearing walls and non-load-bearing walls.
In general, the full-frame structure of the room type, the pressure from the frame, the wall itself without force, the wall can be removed. Half-framed room type, the wall below the frame is a non-load-bearing wall, removable; and most of the rest of the wall is a load-bearing wall and cannot be removed.
Brick-type rooms are generally not high on the floor, and the top of the door and the window are pierced with beams. Therefore, care must be taken when demolition of walls, doors, windows and doors, and the position and width of the wall must not exceed the position of the doors and windows. And width.
Remodeling doors and windows to affect house shockproof
Generally speaking, the seismic strength of a house is determined by the horizontal area of ​​the wall. Adding a door or window or arbitrarily increasing the area of ​​the original door and window will lead to a decrease in the seismic performance. Therefore, the owners have to consult professionals for the shift and expansion of doors and windows.
In addition, the owner is more commonly used in the decoration is the broken wall set shoes. If the shoe is not large, the security threat to the wall is not great. However, if the shoe cabinet is too large, and the over-the-sole beam is omitted above the shoe, it will not play a load-bearing role.
In addition, in order to expand the area leading to the balcony house, some households opened up the partition wall between the balcony and the living room, instead of floor-to-ceiling windows and floor-to-ceiling sliding doors. Because the balcony is generally a beam-beam structure, the removal of the partition wall will cause the balcony to lose its proper support.
How to see if it is a bearing wall
Whether the wall is a load-bearing wall depends on whether the wall itself is bearing.
Walls can be divided into horizontal wall bearing, vertical wall bearing, vertical and horizontal wall mixed bearing and part of the frame bearing. Cross wall loading is used in small space buildings. When the vertical wall is under load, the upper load is carried by the vertical wall, that is, the floor and the roof are supported on the vertical wall. At this time, the horizontal wall is a non-load-bearing partition wall. The load-bearing wall is suitable for buildings that require more flexible layout, such as exhibition halls. Part of the frame load bearing refers to the large area of ​​the room, the outer wall plus the inner column combined into a semi-framed load-bearing wall or the bottom layer is the frame load-bearing, the upper layer is the load-bearing wall bearing, and the beams and columns replace some of the load-bearing walls.
The thick solid line in the construction drawing and the wall under the non-supported beam in the ring beam structure are bearing walls
Personal decoration can be divided into load-bearing walls and non-load-bearing walls by combining the following points:
1, distinguish from the housing structure:
In general, all walls of a brick-concrete structure are load-bearing walls; walls inside a frame structure are not generally load-bearing walls.
2, from the housing level: General middle and low-grade residential buildings, villas are brick-concrete structure. High-end are all more than frame structure.
3. Distinguish from the material of the wall tile: The wall of the general standard brick is the load-bearing wall, and the air-filled brick is the non-load-bearing wall.
4, from the wall thickness: 150mm thick wall is a non-load-bearing wall, such as toilets, kitchen more.
5, according to the division of the beam and the wall to distinguish: The oblique brick method must be a non-load-bearing wall. The tight integration of walls and beams may be load-bearing walls;
6, judged by sound: knock wall, there is a crisp echo, is a light wall, and load-bearing wall should not have too much sound.
7, the indoor corner or the wall in the middle of the pillars protruding out of the eight is a frame structure
In general, all walls of a brick-concrete structure are load-bearing walls; walls inside a frame structure are not generally load-bearing walls. Of course, as far as the structure of the house itself is concerned, whether the wall is a load-bearing wall or not should be carefully studied and checked after actual survey on site.
