The demolition of the main body is an important one in the decoration process. It is related to the safety of the entire home improvement process. However, many people arbitrarily dismantled and changed the main body during demolition and reform, resulting in endless problems in the future. Today, Xiao Bian gave everyone an explanation. Say what minefields cannot be moved during the main demolition process!
Renovation of the "restricted area"
First, bearing wall
In the renovation, the load-bearing wall cannot be changed and many people know it. But what kind of wall is a load-bearing wall, not many people can make it clear. Generally, in a brick-concrete structure, all prefabricated walls cannot be dismantled or doors can be opened; brick walls larger than 24 cm are also load-bearing walls and cannot be removed or modified. The walls that are knocked on by the “quiet voice†are mostly non-bearing walls and can be demolished. In addition, some people open the window on the load-bearing wall, which also undermines the weight of the wall. It is also not allowed.
If you want to demolish the wall in the house during the renovation, it is best for construction professionals to look at it to determine if it is a load-bearing wall before construction. Prior to construction, the property management department should also report to the record and be approved for construction.
Second, reinforcement in the wall
If the structure of the house is better than that of an adult, the steel bars in the wall are the bones of people. If the steel is damaged when the pipeline is laid, it will affect the bearing capacity of the wall and the floor. In the event of an earthquake, such walls and floors can easily collapse or break.
Third, pillars in the room
These pillars are used to support the upper floor slabs. After the upper floors are removed, they will fall, so they cannot move.
Fourth, the short side of the balcony
There is a window on the wall between the general room and the balcony. These doors and windows can be changed, but the walls below the windows cannot be moved. This wall is called "weight wall" and it acts like a scale to provoke a balcony. Demolition of this wall will reduce the bearing capacity of the balcony and cause the balcony to fall.
Fifth, the "three defenses" or "five" doors
The door frames of these doors are embedded in concrete. If the doors are demolished, they will damage the building structure and reduce the safety factor. It also destroyed the building structure at the entrance and it was even more difficult to reinstall the new door.
Sixth, waterproof layer for bathroom and kitchen
There is a waterproof layer under the ground in these places. If it is destroyed, the downstairs will become a water curtain hole. Therefore, be careful not to damage the waterproof layer when you replace the floor material. If you rebuild after destruction, you must do a “24-hour water seepage test†that is, watering in the kitchen or bathroom. If you do not leak after 24 hours, you must be qualified.
" Sensitive area" in decoration
First, bathroom squatting pan
Some old houses also use old-style squat toilets. If you want to change to a toilet, be careful. Because the squatting pan is generally under water, and the toilet is generally under water, replacing the toilet means changing the sewer. This kind of construction is difficult, and the original waterproof layer must be destroyed. If it is not properly installed, it is not a water seepage downstairs.
Second, heating and gas pipelines
The installation and demolition of gas pipelines must be done by a professional construction company of the gas company. The decoration company cannot “do it†and it must not cover the water meters, electricity meters and gas meters during the renovation. For heating and heating pipes, you must also be cautious because the location of the heating in the room directly affects the temperature in the winter room. If the demolition is not properly modified, it is not affected by heating. It is heating and running water.
