Method of wall reinforcement

The wall is an important part of the building, in the reinforcement of the wall, according to the stress situation and the material is divided into bearing wall and non bearing wall, according to the structure is divided into solid wall, sintered hollow brick wall, cavity wall, composite wall and cast-in-place concrete wall.

(wall strengthening)

The wall is an important part of the building. Its function is to bear the weight or to protect and separate the space.If the wall has a safety problem, what should we do for the wall reinforcement?

First of all, we analyze the reasons for the hidden dangers of the wall.

1) the reinforcement ratio of the wall is not enough;

2) the section size or reinforcement of the edge members is not in accordance with the requirements of the standard and the reinforcement of continuous beams.

3) according to the actual situation, the wall needs to be treated with opening.

4) wall bearing capacity does not meet the requirements of the standard; wall size, reinforcement and axial compression ratio do not meet the design requirements;

Solve the problem:

1） We often use the enlargement method to deal with the problem. The strengthening principle of increasing section reinforcement method is to increase the area of the original member or increase the reinforcement ratio, so as to improve its bearing capacity, stiffness and stability, or to change its natural frequency.

2）The openning problem.First of all, we should use the cutting machine or the core drill to make the construction to minimize the damage to the wall. During the opening of the hole, the original reinforcement bar that the wall is cut off should have a certain length. The steel bar should be bent and welded properly, and some concrete will be poured to anchor.Secondly, according to the size of the opening, the carbon cloth or steel plate is wrapped around the hole to make it a whole to achieve the overall force.
