In the home decoration, we all want to make our home decoration exquisite and beautiful, but one thing has always been a problem we can't ignore - safety. The pattern of buying a house doesn't like it. Usually we choose to slot the wall. Do you know if we can slot the load-bearing wall? The following small series will introduce the national regulations for the bearing wall of the load-bearing wall :
First, the big taboo of the load-bearing wall slotting
1. The load-bearing wall cannot be removed.
During the decoration process, the load-bearing wall cannot be removed. What wall is the load-bearing wall? Generally, in the “brick-concrete†structure, all prefabricated panels cannot be removed or opened; more than 24 cm of brick wall is also a load-bearing wall. It can't be changed. The walls that are knocked up with "empty sound" are mostly non-bearing walls that can be dismantled. Some engineering teams open the door and open the window on the load-bearing wall, which will also damage the weight of the wall and is not allowed. Before the construction, it should be reported to the property management department for record, and approved before construction.
2, load-bearing beams and columns are not removable
These beams and columns are used to support the upper floor slab. After the detachment, the upper slab will fall down, which is very dangerous, so it is not free to dismantle and destroy.
3. Steel bars in the wall
If the structure of the house is more than the body of an adult, the steel bars in the wall are the bones of the person. When you are in the slotting line, avoid the steel bars. It is best not to cross-cut. If the steel bars are damaged when the pipeline is buried, it will affect the bearing capacity of the wall and the floor. Such walls and slabs can easily collapse or break in the event of an earthquake.
4, the low wall next to the balcony is not removable
There is a window between the room and the balcony. These doors and windows can be removed, but the walls below the window cannot move. This wall is called the “weight wall†and it acts like a scale to provoke a balcony. The wall was demolished, causing the load-bearing capacity of the balcony to drop, causing the balcony to fall, with unpredictable consequences. The door of the "three defenses" or "five defenses", the door frames of these household doors are embedded in the concrete, if the demolishing will damage the building structure and reduce the safety factor. And it destroyed the building structure of the doorway, and it was even more difficult to reinstall the new door.
5, waterproof layer of bathroom and kitchen
In these places, there is a waterproof layer under the ground. If it is destroyed, it will become a "water curtain hole" downstairs. Therefore, when you replace the floor material, be careful not to damage the waterproof layer. If it is rebuilt after the damage, it must be re-waterproofed. After the "24-hour water seepage test", it will be qualified if it does not leak water.
Second, the damage of the load-bearing wall slotting
1. Holes and slots in the load-bearing wall will weaken the masonry resistance cross section, reduce the bearing capacity of the masonry, and reduce the safety performance of the house. In addition, when grooving or drilling, whether it is hand-milling or impact drill Chiseling will cause large vibrations in the wall, causing loosening of the gray joints, destroying the bond between the mortar and the bricks or hollow blocks, thereby reducing the shear and compressive strength of the masonry.
2. If you must slot the strange wall, the load-bearing wall should not exceed 30 cm, and the non-bearing wall should not exceed 50 cm, otherwise it will easily cause wall cracking. The current shear wall is subjected to a large amount of force in parallel, and is most afraid of such lateral slotting. The usual vertical pressure also causes cracks in the wall. Once the earthquake, the large lateral tension is even more terrible. If you dig a 5 cm deep, 3 m long transverse groove on the load-bearing wall, the damage is equivalent to the overall removal of the 1 m wide load-bearing wall. Any form of damage to the load-bearing structure will reduce the seismic performance of the building. To make an inappropriate analogy, such as a piece of glass with a certain thickness, is not easy to break. However, if a diamond is used to make a mark on the glass, and then force is applied, the glass is broken along the crossed mark. The slotted load-bearing wall, like the glass that has been cut by diamonds, is easily broken in the face of a strong earthquake.
Through the above introduction, we can see that it is not advisable to load the load-bearing wall during home decoration. Although modern decoration, many consumers will slot the wall for the convenience of wiring, but the slot on the load-bearing wall is open to question. Therefore, Xiao Bian here advises friends, for the safety of their own and others, or do not slot on the load-bearing wall. If you want to know more about decoration, please continue to pay attention to the decoration home network.
