Be vigilant! Don't touch the 4 major minefields in decoration, demolition and modification!

In the process of decoration, demolition and modification, when determining whether a certain house structure can be modified, do not first consider it from the perspective of aesthetics, but from the perspective of safety. . So what are the "minefields" for renovation and demolition projects? Today I will explain it to you.

minefield 1 load bearing wall

After the decoration personnel entered the site and made a confession, it was to demolish and modify the wall and bury the pipeline. In the process of demolishing and modifying the wall, many owners often like to demolish the load-bearing wall without permission for the overall decoration effect of the house, which is very undesirable.

In general brick-concrete buildings, all prefabricated panel walls are load-bearing walls and cannot be demolished or opened or opened. Brick walls over 24 cm are also load-bearing walls. Don't move the load-bearing wall during decoration, and don't make a large hole in it.

Tip: Removing the load-bearing wall, opening doors, opening windows and thinning the load-bearing wall on the load-bearing wall not only directly destroys and weakens the bearing capacity of the load-bearing wall, but also destroys the integrity and earthquake resistance of the house. It may also cause the cracking and cracking of the adjacent walls, the strength and bearing capacity of the walls will decrease, and the walls and floors of the upper and lower floors will crack, resulting in structural damage. Such walls and floors can easily collapse or break in the event of an earthquake.

Minefield 2 Gas Pipeline

Residents or decoration personnel without permission to dismantle and modify the gas pipeline and encapsulate the gas valve can easily cause gas leakage. When the gas pipeline is enclosed, the gas leakage is not easy to be detected, and the leaked gas is not easy to spread and gather locally. Before use, there is no professional safety inspection, and it will inevitably cause an explosion in the event of an open flame.

Tip: Gas facilities have strict technical specifications and safety requirements for design and installation, and must be constructed by professionals. If the residents really need to change the gas pipeline when decorating their rooms, they should apply to the gas supply unit, and the gas supply unit will conduct an on-site survey and put forward opinions. If it can be changed, the gas supply unit will issue a construction plan, which will be operated by professionals. Should have professional qualifications.

Minefield 3 Heating Pipes

It is also more common to dismantle and modify the heating pipes and the upper and lower water pipes during the decoration. Heating pipes and upper and lower water pipes have a common feature, that is, these pipes form a whole system within a certain range, and each household cannot be completely independent. Therefore, when modifying such pipelines, care should be taken, and all modifications should be based on the premise of not affecting the entire system.

Tip: There are many drawbacks to dismantling the heating system randomly. After the originally designed heating system is modified, the pressure will change. After the heat balance is broken, the heating will be out of balance, resulting in very hot and cold. It is difficult to ensure that the heater does not leak after the modification.

Minefield 4 Balcony "Counterweight Wall"

Generally, there is a door and a window on the wall between the room and the balcony. These doors and windows can be removed, but the wall below the window cannot be removed, because this part of the wall is a "counterweight wall", which acts like a weight to lift the balcony. effect. Many owners believe that the counterweight wall has little effect, blocking sunlight from entering the room and affecting the lighting of the room. Therefore, it is often considered to remove the counterweight wall to form a wide pass at the balcony.

Tip: Removing the counterweight wall will reduce the bearing capacity of the balcony and cause the balcony to fall. Removing the counterweight wall will change the original force of the house structure, and may also reduce the load-bearing capacity of the balcony, and even have the risk of collapse. Some old house balconies are of a pick-up type structure. Once the counterweight wall is removed, the wall structure that "presses" the balcony will be damaged and the bearing capacity of the balcony will be weakened.
