Four principles of building structural strengthening

• For “brick and concrete” structure of the building, all precast slab walls can not be removed, nor open the windows.

Brick walls with a wall thickness exceeding 24 cm are generally load-bearing walls and can not be easily dismantled and rebuilt. Besides the load-bearing walls, the light wall may not be demolished. Some light walls also bear part of the weight of the house. For example, the light wall below the beam can not be demolished because it also bears part of the weight of the house. Dismantling, it will destroy the structure of the house as well. What walls can be removed? As a partition wall, the light wall and hollow slab can be dismantled. Because the partition is completely free from any pressure, the value of existence is to separate the space, and the demolition will not have any impact on the structure of the house.

• The dwarf walls at the edge of the balcony can’t be removed or changed.

The wall between the general room and the balcony has a window, these doors and windows can be dismantled, but the wall below the window can not be dismantled, because the wall is a “weight wall”, it plays the role of the balcony like the weight of a weight. If the wall is dismantled, it will reduce the load of the balcony and cause the balcony to fall down.

• The beam and column in the room can not be changed.

The beams and concrete columns are used to support the upper floor, and the demolition or reconstruction will cause the upper floor to fall off, which is quite dangerous, so the beam and column can never be dismantled or reformed.

• The steel bar in the wall can’t move.

When laying pipelines, if the steel bars are damaged, the bearing capacity of the walls and floors will be affected, leaving behind a hidden danger.
