What parts cannot be modified during decoration? 9 sensitive restricted areas that must not be touched in home decoration.

Many owners may not know that there are actually many parts of the house that cannot be moved during decoration. These places are what we usually call "restricted areas" or "sensitive areas" for decoration. If you don't understand the structure and demolish it without authorization, it will not only affect the overall beauty of the house, but also bring certain safety hazards to yourself or your neighbors. So where do these "restricted areas" or "sensitive areas" specifically refer?

1. Load-bearing walls

Many people know that load-bearing walls cannot be demolished or modified during decoration. But not many people can tell clearly what kind of wall is a load-bearing wall. Generally in buildings with a "brick-concrete" structure, prefabricated panel walls cannot be dismantled or doors or windows must be opened; brick walls exceeding 24 cm are also load-bearing walls and cannot be dismantled or modified. Most of the walls that make a "hollow sound" when struck are non-load-bearing walls and can be demolished and modified. In addition, if someone opens doors or windows on a load-bearing wall, this will also damage the load-bearing capacity of the wall and is not allowed.

2. Steel bars in the wall

If the structure of a house is compared to a human body, the steel bars in the wall are human bones. If the steel bars are damaged when burying pipelines, it will affect the bearing capacity of the walls and floors. In the event of an earthquake, such walls and floors can easily collapse or break.

3. Beams and columns in the room

These beams and columns are used to support the upper floor slab. After being removed, the upper floor slab will fall down, so it cannot be moved.

4. Low wall by the balcony

Generally, there is a door and a window on the wall between the room and the balcony. These doors and windows can be removed and modified, but the wall below the windows cannot be moved. This section of wall is called the "counterweight wall", which acts like a weight to lift up the balcony. Removing this wall will reduce the bearing capacity of the balcony, causing it to fall.

5. "Three-proof" or "Five-proof" doors

The door frames of these doors are embedded in concrete. If they are demolished and modified, the building structure will be damaged and safety will be reduced. coefficient. Moreover, if the building structure of the door is damaged, it will be even more difficult to install a new door.

6. Waterproof layer in bathroom and kitchen

There is a waterproof layer under the ground in these places. If it is damaged, the downstairs will become a "water curtain hole". So when you change the floor material, be careful not to damage the waterproof layer. If it is rebuilt after damage, be sure to do a "24-hour water seepage test", that is, fill the kitchen or bathroom with water. If there is no leakage after 24 hours, it will be considered qualified.

7. Squatting toilet in the bathroom

Some old houses still use the old squatting toilet. If you want to replace it with a sitting toilet, you must be careful. Because squatting toilets usually drain from the front, while toilets usually drain from the rear, changing the toilet means changing the sewer pipe. This kind of construction is difficult and the original waterproof layer must be destroyed. If installed improperly, water will either seep downstairs or the toilet will not drain.

8. Heating and gas pipelines

Installation and removal of gas pipelines must be done by professional construction personnel from the gas company. The decoration company cannot "do it for you" and cannot cover it during decoration. Water, electricity and gas meters. You also need to be careful when it comes to heating and heating ducts, because the location of the heating indoors directly affects the indoor temperature in winter. If it is not properly dismantled or modified, either the heating will be affected or the heating will run out of water.

9. Original steel windows

Some residents replaced the original steel windows with aluminum alloy windows because they did not look good. Since a few decoration companies currently use small-sized profiles in order to be cheap, or simply shoddy products, some aluminum alloy windows are far less solid than steel windows. The use of such aluminum alloy windows is prone to falling off, especially in high-rise buildings.
