What projects are included in the main demolition? What are the precautions for the main body demolition? department

? Whether it is the renovation of old houses or new houses, once you are dissatisfied with the original structure of your house, it will involve the demolition and renovation of the main body. Today, Bian Xiao, a famous sculpture, will give you a detailed introduction of the contents of the main demolition and the matters needing attention in the renovation.

First, the main contents of the demolition

The main demolition includes wall demolition, new wall construction, heating demolition, wall demolition, plastic steel replacement and so on. The demolition and modification of the main body includes two items: demolition and modification. Among them, "demolition" refers to the demolition of non-bearing walls, floor tiles, ceilings, doors and windows that need to be transformed. "Renovation" refers to the part that remains intact as a whole. Simply put, it is to renovate or dismantle a department. For example, if you want to build a half-wall partition, then you have to tear down part of the wall and keep part. Replace doors and windows, keep door frames and replace door bodies.

Second, the main demolition process

1, according to the planning drawings.

It is particularly important to make a good design plan before the main body is demolished. Some walls can't be demolished at will. It is necessary to decide where they can be demolished and where they can't be demolished under the professional judgment of professional designers, and then carry out construction according to the drawings.

2. Report the property.

Some communities do not allow secondary demolition. It is prudent to report to the residential property and get property support before starting work.

3, protection engineering

The framework of the construction site should be set up before the main body is demolished, and then protective measures should be taken for the public area to avoid unnecessary damage caused by the main and auxiliary materials during transportation and decoration. After the demolition and reconstruction project is completed, a large amount of building materials waste will be left, which needs to be removed in time so as not to affect the implementation of the next project.

Second, the points for attention in the demolition and reconstruction

1. Never tear down or change the load-bearing wall. The load-bearing wall supports the weight of the whole house, and its demolition will weaken its bearing capacity. The load-bearing wall will also affect the integrity and seismic capacity of the whole building, and life safety is paramount, so the load-bearing wall cannot be dismantled and changed at will.

2. The counterweight wall cannot be dismantled and changed at will. Counterweight wall refers to the wall between the guest dining room or bedroom and the balcony, which plays a bearing role on the balcony. If it is demolished, the bearing capacity of the balcony will be reduced, and in severe cases, the balcony will sink and collapse.

3. The beams on the house and the lintel above the doorway shall not be removed. The function of the beam is to support the bearing capacity of the superstructure or the wall on the door. If it can't be demolished, it will crush the door and lead to the collapse of the house.

4. Not all non-bearing walls can be removed. Many people think that since the load-bearing wall can't be demolished, I'll demolish the non-load-bearing wall. Actually, this is a misunderstanding. Non-load-bearing walls also have the function of supporting the weight of walls and resisting earthquakes. If the whole building is demolished and rebuilt at will, the seismic capacity of this building will definitely weaken. For some non-bearing walls that are not necessary to be demolished, Bian Xiao suggested that it is best not to dismantle them.

5. Before the main body is dismantled and changed, the corresponding circuit transformation scheme needs to be done well. The circuit reconstruction is affected by the demolition of the wall, and there will be circuit pipelines in the wall of the old house. In order not to affect the implementation of the next construction project, the circuit transformation also needs planning.

6. The demolition and reconstruction of the main body is not a trivial matter. In the demolition and reconstruction of the main body, we must find professionals or decoration companies to understand the basic structure of the house before making a decision. Random demolition and reconstruction is likely to cause danger. Before construction, it is necessary to declare to the property company, and the construction can only be carried out after approval.

There are many matters needing attention in the demolition and reconstruction of the main body, and problems that cannot be solved may be encountered in the construction process. It is extremely important to find an experienced decoration company.
