Frequent earthquakes warn decoration not to forget safety

frequent earthquakes in the world over the years have sounded an alarm to citizens preparing for home decoration: decoration must not ignore safety, act casually, and leave hidden dangers. Random demolition and modification of structures reduce seismic resistance. Although modern buildings basically consider seismic resistance, the wrong decoration method is likely to reduce the seismic capacity of a house or even a building, resulting in accidents

non bearing walls cannot be demolished randomly.

it is understood that at present, changing the indoor structure at will during decoration, especially dismantling and modifying the bearing wall without authorization, has become a major reason for the weakening of the seismic performance of the house. Many families will carry out renovation when decorating, breaking down the indoor load-bearing wall or opening doors and windows on the load-bearing wall, removing the beams and columns in the room, randomly removing the low wall under the balcony side window or destroying the reinforcement in the wall. In our traditional concept, the load-bearing walls in the house cannot be demolished, but the non load-bearing walls can be demolished. In fact, this is a big misunderstanding

in fact, not all non bearing walls can be demolished and modified at will. The so-called non bearing wall refers to the house composed of reinforced concrete column array frame. The floor is supported by the horizontal array, the array is supported by the column, and the column is supported by the foundation. This structure is usually visible indoors. Most of the walls between the column arrays are filled with hollow bricks or ordinary bricks, which are generally non bearing walls. Many people believe that non bearing walls are not load-bearing, but the actual situation is not the case. Because compared with the load-bearing wall, the non load-bearing wall is a secondary load-bearing component, but at the same time it is an extremely important support for the load-bearing wall. When burying pipelines, the reinforcement in the wall and floor will be damaged, which will affect the bearing capacity of the wall and floor. In case of earthquake, the wall and floor are easy to collapse or fracture

pay attention to the decoration materials and quality

if the decoration materials and construction technology are unqualified or nonstandard, it will also affect the seismic capacity of the decorated house. The hanging lamp is hung on people's heads, and the load-bearing capacity of the hook is very important. According to national standards, the hook must be able to bear 4 times the weight of the hanging lamp before it is considered safe. Therefore, when decorating the living room, the load-bearing capacity of the chandelier must be checked and tested. Some wooden base courses, especially the ceiling surface, may collapse after the earthquake if the size of the wooden strips used does not meet the requirements, or the construction technology does not meet the standards

if the density of the expansion screw of the ceiling does not meet the standard, the light steel keel is easy to collapse after the earthquake if the main keel is not used or the density is too small. For some residential chandeliers falling after the earthquake, experts explained that this was caused by the lack of professional expansion screws or non-standard installation technology when installing the chandeliers; The collapse of wall tiles may be due to the unqualified mixing proportion of cement mortar, which leads to the lack of adhesion, which leads to the regret that the outside world will fall down after a slight vibration. Therefore, attaching importance to the quality of materials and construction technology in the decoration process can also effectively improve the seismic capacity of the decorated house
