Technical Field

The invention belongs to the technical field of building construction, and particularly relates to a method for repairing wall cracks.

Background

At present, in the field of building engineering, a wall body structure formed by embedding reinforcing steel bars inside and pouring concrete is widely applied, because the brittleness of the concrete structure is extremely high, cracks often inevitably appear on the wall body after the wall body is used for a long time, if the cracks are not treated in time, the cracks can continue to grow, the water tightness of the concrete structure is reduced, the leakage is caused, the service life of the wall body is influenced, and some walls can not be used even, so that the potential safety hazard is great. In the prior art, the traditional method for repairing concrete cracks adopts water-based adhesive to mix cement for repairing, but the traditional method is difficult to reach the current anti-leakage repairing standard and is gradually eliminated, most of the existing methods for repairing wall cracks are temporary, can crack after a long time, and can not keep the stability of cracks, and the cracks are more and more large along with the lapse of time, so that a novel method for repairing wall cracks is needed to solve the problems and meet the requirements of people.

Disclosure of Invention

The present invention is directed to a method for repairing cracks in a wall, so as to solve the above problems.

In order to achieve the purpose, the invention provides the following technical scheme: a method for repairing wall cracks comprises the following steps:

cleaning the position of a wall surface with cracks, polishing and flattening the crack openings by using abrasive paper, and cleaning up dust and broken stones in the wall gaps by using a high-speed blower;

step two, preparing a steel bar with the common diameter of D, using a cutting machine to cut round holes in two wall surfaces which are adjacent to the wall body with the crack at 90 degrees, and fixing the two parallel wall surfaces by the steel bar penetrating through the round holes;

respectively forming bolt holes at the upper and lower parts of the two sides of the crack, and fixing a fixing plate at one side of the crack through the bolt holes, wherein the area of the fixing plate is larger than that of the crack;

putting a proper amount of cement, stones, sand, epoxy resin and water into a stirrer, and uniformly mixing to obtain concrete;

fifthly, adding concrete into the cracks to enable the concrete to completely fill the cracks, then trowelling the concrete filling layer and the wall body, and then manufacturing a baffle plate with the same size and position as the fixing plate on the other side of the cracks;

and step six, finally, disassembling the baffle and the fixing plate, and performing watering maintenance.

Preferably, both ends of the steel bar in the second step are provided with threads, the part of the steel bar, which exceeds the wall body, is provided with a stop block, and the stop block is fixed on the wall surface through a bolt.

Preferably, the diameter of the steel bar in the second step is 1-1.5 cm.

Preferably, the mass ratio of the cement, the stone blocks, the sand, the epoxy resin and the water in the fourth step is 27 parts of the cement, 13 parts of the stone blocks, 35 parts of the sand, 13 parts of the epoxy resin and 27 parts of the water.
