According to reports, the demolition of the bearing wall will lead to structural changes in the force transmission system, resulting in a large cracks in the floor, which in turn will lead to the destruction of the overall structure, will become a major security risk, especially when it comes to earthquake disasters. In the renovation, there are some owners who dismantled the walls connecting the balconies, doors and windows, and expanded the size of the original doors and windows. The experts reminded that if the walls between the doors and windows are load-bearing walls, they must not be arbitrarily expanded.
The reporter found that in the traditional concept, many people believe that the load-bearing wall in the room cannot be demolished, but the non-bearing wall can be demolished. This is actually a major misunderstanding.
According to a survey conducted by China National Metallurgical Engineering Group's civil engineers, not all non-load-bearing walls are free to demolition. Compared to bearing walls, non-load-bearing walls in addition to the weight of the wall, including the stacking weight of the wall in the same location on the upper floors, but also the structural design of the seismic wall. In other words, if an earthquake occurs, these non-load-bearing walls will bear seismic forces together with the bearing walls. Therefore, the demolition of non-load-bearing walls is even more cautious for households with lower floors. Huzha emphasized that although it is not a big problem for a single family to dismantle a non-load-bearing wall or make an opening on the wall, if the residents of the whole building are arbitrarily dismantled and reformed, the resistance of the building will be greatly reduced. .
In addition, experts advise that do not arbitrarily change the bathroom structure. Because there are many sewage pipes in the bathroom, large holes are needed, the floor is prefabricated, and the inside is reinforced, which is the most solid place in the house. Therefore, the bathroom is often the first choice for people when they are shock absorbers. The decoration is beautiful and at the expense of its practicality.
In addition, in addition to the structural experts’ reminding of the demolition and renovation of interior wall decoration, Wang Peng, interior design teacher of Inner Mongolia Normal University, also enhanced the earthquake-resistant safety of interior decoration, and gave some suggestions on circuit reconstruction, top surface and concealed project decoration. Suggest:
First of all, do not arbitrarily dismantle the water, electricity, and gas lines during the renovation. Reduce the possibility of adverse consequences such as leakage, leakage of electricity, and leakage of gas and natural gas from accidents when water and electricity are used in the process of accidents.
Second, when decorating the living room, the bearing capacity of the chandelier must be checked and tested. According to national standards, the hook must be able to suspend the pendant 4 times the weight to be safe.
Again, the top decoration should not be too complicated. According to Wang Peng, some decoration teams now only use the ceiling style to win consumers' favor, but there is a big security risk in construction quality. Some even appear to fall off the ceiling after one or two years of occupancy, which is very dangerous.
Finally, besides hanging objects, the wall decorations should also be made of non-breakable materials. In addition, the installation of cabinets also requires attention to the stability of the suspension.
