Don't tear down and change these seven places at will. I didn't understand them at first, so I was searched by the property three times.

At present, many families rarely do not change the original apartment structure when decorating, but if they want to demolish and renovate, they should also pay attention to the methods and principles of demolishing and renovating. Don't tear down and change these seven places at will. My family didn't understand it when decorating. We were approached three times for this property, and finally I found out which places can't be demolished and changed. Let's see what's going on together.

First, the decoration can't be dismantled and changed at will.

When the new house is in hand, I believe everyone will be eager to start decorating! Many people are secretly preparing for a big demolition and a big change. The apartment doesn't like it. Change it! The bathroom doesn't like it, change it! Small room window? Change! However, you should know that these seven places of new house decoration cannot be demolished casually, otherwise it is easy to leave hidden dangers and destroy the house in vain!

1, the first place that cannot be changed is the load-bearing wall. Some friends know that the load-bearing wall can't be torn down, but they don't know that their own wall is a load-bearing wall. In this way, security risks are left behind by mistake. Before you dismantle it, you can find a floor plan. The thick black line below represents the load-bearing wall. If you are still not sure, ask what can't be changed in the property.

2, can't change the gas pipeline without authorization. Once the gas pipeline is dismantled and changed improperly, it will not only affect the normal use, but even leave a safety hazard. The reconstruction of gas pipeline should first ask the gas company to carry out safety assessment. This is really feasible, and then they will modify it. It is impossible for a decoration company to do it.

3. Master bedroom bathroom. Some families think that double bathrooms are chicken ribs, and it is unreasonable to change the master bedroom into a study and cloakroom. First, there is a sewer in the bathroom, and the sound of flushing upstairs will be embarrassing. Second, once the waterproof upstairs is not done well, the walls of your home are also prone to be affected with damp, and the furniture in the cloakroom or study is more prone to be affected with damp and mildew.

4. Window on the wall. Some rooms have no windows or the windows are relatively small, so some owners have the idea of opening windows privately. It should be noted that, first, the property in the general community will not allow you to change the window without permission; Second, it is not easy to control the falling direction of the wall muck by breaking the wall and opening the window. Once the waste brick falls and hurts people, it will be bad.

The balcony of the living room is open. Some people think that the living room is not big enough, so they want to connect the balcony with the living room, which is also very dangerous. The demolition and modification of this part of the wall will destroy the load-bearing structure of the house, leaving hidden dangers.

6. Don't punch holes in the beam. If you have water, electricity or central air conditioning at home, you must remember that there can be no holes in the beam, but if you have to, you should pay attention to avoid the main reinforcement on the beam.

7. Be careful when digging niches to make embedded cabinets. On the one hand, it will destroy the bearing capacity of the wall, on the other hand, it will make the sound insulation effect of thin-walled rooms worse.

Second, what are the precautions for interior decoration demolition?

1. The load-bearing wall cannot be removed.

A load-bearing wall is a wall that supports the weight of the floor. Brick walls with a thickness of more than 24 cm are generally load-bearing walls, which can neither be demolished nor smashed nor dug. If the load-bearing wall must be removed, the original design unit or a design unit with the same qualification as the original design unit is required to give a design plan for modification and reinforcement before the load-bearing wall can be removed.

2. Some counterweight walls cannot be removed.

Some counterweight walls are also called lightweight walls and cannot be removed. For example, the light wall under the beam cannot be demolished because it also bears part of the weight of the house. In addition, there is usually a door and a window on the wall between the room and the balcony. These doors and windows can be removed, but the wall under the window can't be removed, because it plays a role in provoking the balcony. If it is demolished, the bearing capacity of the balcony will drop and the balcony will fall.

3. After the door is removed, the door beam must be added.

If the lintel is not added to the back door opening, the bearing capacity of the door opening will be reduced, which is very easy to cause collapse. So generally speaking, you must make concrete lintels to increase the bearing capacity of the doorway. In addition, door frames are usually embedded in concrete. If it is demolished and rebuilt, it will destroy the whole structure of the building, reduce the safety factor and make it more difficult to reinstall the door.

The beams and columns in the room can't be changed.

Beams and columns are generally used to support upper floors. Demolition and modification will cause the upper layer to fall off, and the risk factor is quite high. Therefore, under no circumstances can the beams and columns of the house be dismantled.

5, the wall does not pull the wall reinforcement

Between the original wall and the new wall, it is necessary to pull steel bars for connection and fixation. Adding steel bars can improve the seismic capacity of the new wall and avoid cracks. If the wall reinforcement is not pulled, it will affect the firmness of the wall and may cause hidden dangers such as cracking and inclination.

My family didn't know this knowledge before decorating the new house, so I was searched by the property several times. Now, as an experienced person, I finally understand the truth of demolition and transformation. If you want to dismantle and change the interior, you should pay attention to the method of dismantling and changing. It is suggested that the above places should not be demolished during renovation, and you can also consult your own property management personnel first.
