Renovated "forbidden zone"

1. Load-bearing wall: The load-bearing wall cannot be demolished during renovation. Many people know it. But what kind of wall is the load-bearing wall, there are not many people who can make it clear. Generally, in the "brick-concrete" structure of the building, all prefabricated slab walls can not be removed or opened to open windows; brick walls over 24 cm are also load-bearing walls, which cannot be dismantled. The walls that are knocked up with "empty sound" are mostly non-bearing walls that can be dismantled.

In addition, some people open the door and open the window on the load-bearing wall, which will also damage the weight of the wall, and it is not allowed.

If you want to demolish the walls in the house during the renovation, it is best to ask the professional person to look at it and determine if it is a load-bearing wall. Before the construction, it should be reported to the property management department for record, and approved before construction.

2, the steel in the wall: If the structure of the house is more than the body of the adult, the steel in the wall is the human bones. If the steel bars are destroyed when the pipeline is buried, it will affect the bearing capacity of the wall and the floor. Such walls and slabs can easily collapse or break in the event of an earthquake.

3. Beams and columns in the room: These beams and columns are used to support the upper floor. After the floor is removed, the upper floor will fall, so it cannot move.

4, the low wall next to the balcony: the wall between the general room and the balcony, there is a window. These doors and windows can be removed, but the walls below the window cannot move. This wall is called the “weight wall” and it acts like a scale to provoke a balcony. Demolition of this wall will cause the load-bearing capacity of the balcony to drop, causing the balcony to fall.

5, "three defenses" or "five defenses" of the door: the door frame of these doors is embedded in the concrete, if the demolishing will damage the building structure, reduce the safety factor. And it destroyed the building structure of the doorway, and it was even more difficult to reinstall the new door.

6, the waterproof layer of the bathroom and kitchen: these places have a waterproof layer under the ground, if it is destroyed, the downstairs will become a "water curtain hole." Therefore, when you replace the floor material, be careful not to damage the waterproof layer. If it is rebuilt after the damage, it must be done in the "24-hour water seepage experiment", that is, in the kitchen or bathroom, if it does not leak after 24 hours.

"sensitive area" in the decoration

1. Toilets in the bathroom: Some old houses also use old-style squatting pans. If you want to change to a toilet, you must be careful. Because the squatting pan is generally the front water, and the toilet is generally water, so changing the toilet, it means changing the sewer. This type of construction is difficult and must destroy the original waterproof layer. If the installation is not proper, it is not water seepage downstairs, or the toilet does not enter the water.

2. Heating and gas pipelines: Installation and dismantling of gas pipelines must be carried out by professional construction personnel of the gas company. The decoration company cannot “work” and cannot cover water meters, electricity meters and gas meters during renovation. For heating and heating pipes, you should also be cautious, because the location of the heating in the room directly affects the temperature in the winter room. If the dismantling is improper, it is not affected by heating, or the heating runs.

3. The original steel window: Some households changed the aluminum alloy window because the original steel window was not good. Because a few decorative companies currently use small-sized profiles for the sake of cheaper drawings, or simply shoddy, some aluminum alloy windows are far less rigid than steel windows. The use of such an aluminum alloy window is liable to cause shedding, especially on high-rise buildings.

Building materials that cannot be used in the renovation

1. Do not use contaminated materials: Some materials contain chemicals that are harmful to the human body and these materials cannot be used. However, most of the current decorative materials are synthetic products, and more or less always contain a little of these substances. Therefore, you should try to choose natural materials. First, open the doors and windows for one week after renovation.

2, can not use over-sinking materials: According to the relevant regulations, natural stone with a thickness of more than 1 cm, is not allowed to be used in home decoration.

The above are some places in the decoration that cannot be dismantled or need to be cautious. When you agree with the decoration company on the design plan, you must keep more in this respect, so as not to bring danger to yourself and your neighbors.
