Many houses inhabited now are of shear wall structure. So if the house reinforcement company needs to open the wall and open the door according to the actual situation, how do we deal with the structural safety hazards? This is a serious problem for house safety.

First, when opening the hole, the house reinforcement company should use a cutting machine or a core drilling machine for construction to minimize the damage to the wall. When opening the hole, the original stressed steel bars that were cut off from the wall should have a certain length, and the steel bars should be bent and welded appropriately, and a certain amount of concrete should be poured for anchoring.

Secondly, according to the size of the opening, a clad steel frame is built around the opening, and the joint surface of the steel frame and the concrete should be filled with adhesive to make it a whole.

House reinforcement companies often use increasing cross-section reinforcement methods to deal with it. The reinforcement principle of the increasing section reinforcement method is a direct reinforcement method that increases the cross-sectional area of the original member or increases its reinforcement ratio to improve its bearing capacity, stiffness and stability, or to change its natural frequency.

The thickness of the newly added concrete layer should be calculated by the house reinforcement company, generally not less than 60mm, and the strength level of the newly added concrete should be one level higher than the original concrete, not less than C25. When appropriate, it is necessary to add steel meshes in the new concrete wall. The steel mesh regulations have been calculated, and the vertical reinforcement should be included, and the transverse reinforcement should be outside, and the new mesh should be reliably connected to the original wall.
