The correct way to tear down the wall

1 structure, the difference needs to be professional.

Wrong way: I don't know the structure of the old house, just proceed from experience, and the demolished part is only a load-bearing wall. After being known by the hotel, it was not only good, but also knocked down part of the wall.

The correct way: The structure of the old house is complex, and it is difficult to distinguish the nature of the wall. Finding ordinary decoration workers is easy to identify mistakes, and it is best to find professional veterans to judge.

The drawings are very important and need to be reconfirmed.

Wrong method: there was an error in the drawing, and the construction personnel didn't pay attention to it, knocking out the cement around the reinforced concrete column. They didn't know it was a load-bearing structure until they hit the steel bar.

Wrong way: In order to make the house look taller, the owner wants to cut off the lower edge of the beam as much as possible. The final reinforcement is exposed outside the wall.

Correct method: When designing a house, we should not only consider everyone's needs, but also consider the beauty of the house, and we should not ignore the original structure. Only when the original structure allows, can we carry out appropriate transformation.

The wall is empty, and the picky should be careful.

Wrong way: Brick walls can be ruled out, but it is also necessary to determine whether there are pipes on the walls. The builder stopped until he saw the pipe. If he knocks on the pipe, it will be very big.

The correct way: don't think that walls are solid, and some walls will have pipes. Before demolition, it is necessary to determine not only whether the wall is load-bearing, but also whether there are pipes or other things on the wall.
