Do not use overweight materials.
In home decoration, sometimes it is necessary to use a lot of overweight materials, which may make the bearing capacity of the house exceed the design standard, leading to the building tilting and sinking. When raising the floor, avoid using reinforced concrete with strong structure; When laying granite and marble, the laying area should be controlled as much as possible; It is best to use light steel keel or wood structure filled with sound insulation material as the wall separating rooms; When making a suspended ceiling, it is necessary to simplify the structure and choose lightweight materials.
Change the structure at will
In order to change the space division of the original bedroom, some residents removed the load-bearing wall or replaced it with lightweight glass without authorization. Some residents cut off the steel bars on the load-bearing wall in order to open the door by digging holes in the wall. These practices can easily lead to floor cracking.
Do not change the use of the house without authorization.
It is extremely dangerous to change the kitchen into a bedroom, because once the gas leaks, the consequences will be unimaginable. It is also not advisable to change the balcony into a kitchen or bedroom, because the bearing capacity of the balcony floor is generally small, and the balcony floor will be stressed after being changed into a kitchen or bedroom, which will hardly cause the floor to break and fall off.
