1. Do not arbitrarily dismantle and change the load-bearing wall body, dismantle and modify the structural members
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.

2. The hanging must be stable, such as chandeliers, hanging cabinets, hanging decorations
Magnificent and luxurious crystal lamps hang high in the halls of hotels, guesthouses, and buildings. Not only are they dazzling lighting effects, but also their distinctive shapes, exquisite materials and exquisite crystal beads create a relaxed atmosphere. Mood.
However, the chandelier hangs on people's heads. The load bearing capacity of the hook is very important. According to the national standards, the hook must be able to suspend the chandelier 4 times the weight to be safe. Therefore, when decorating the living room, the bearing capacity of the chandelier must be checked and tested. Care should be taken during construction to avoid holes in the concrete circular hole plate, drill holes, hang ceilings and install art lighting fixtures.
In addition to the overhead chandelier, the installation of the gantry also requires careful attention to the stability of the suspension. However, at present, the cabinet hanging method has not attracted enough attention from consumers. As a result, many kitchen cabinet companies only pay attention to the surface design, but neglect the suspension method when the cabinet is installed and the functions required for hanging the cabinet. There is a hanging yard in the upper left corner and the left corner of the hanging cabinet. There is a serious quality problem without hanging the cabinet with the hanging yard. The ordinary hanging yard bearing weight is only 35 kg and is exposed type, the quality kitchen cabinet will use 70 kg load-bearing concealed hanging yards, the quality is better, the hanging cabinet can hold more items inside, and make the box body look more beautiful.
3. Do not arbitrarily increase the total weight of floor covering materials
Home decoration should pay attention to the floor of the building not all marbled. Marble is dozens of times heavier than floor tiles and wooden floors. If the floor is entirely covered with marble, the floor may become overwhelmed. Especially in the second floor or above, the weight of the ground decoration materials must not exceed 40 kg/m2 because of the house decoration not identified by the housing safety appraisal station.
4. Do not arbitrarily dismantle water, electricity and gas pipelines
Reduce the possibility of adverse consequences such as leakage, leakage of electricity, and leakage of gas and natural gas in the event of accidental disasters due to minor defects in the hydropower reform process. Avoid the accidents caused by renovation hidden dangers, causing greater losses and casualties in the event of natural disasters. A variety of valve switches ensure convenient operation in emergency situations. It is convenient to quickly close the switch valve when a disaster occurs, and personnel are evacuated as soon as possible to minimize casualties and property losses during a disaster.
