Repairing method and structure for building wall crack

Abstract

The invention discloses a repairing method and a structure for a building wall crack. At first, grooves (2) are polished in the crack along the length direction of the crack (1) at every 3-20 cm before the building wall crack is sealed, filled and leveled up through cement mortar or lacquer putty powder. Then, a metal nail (3) is used in each groove (2) to be embedded into the crack (1). The purposes of preventing deformation and narrowing the crack (1) are achieved by a manner that the metal nail (3) is embedded into the crack (1). At last, a nail head end of the metal nail is covered through the cement mortar (4) and the grooves are filled and leveled up. After the cement mortar is permanently set, the cement mortar or the lacquer putty powder is used for sealing, filling and leveling up rest wall building wall cracks. The repairing structure for the building wall crack not only has the advantages of being easy and convenient to construct, simple in structure and capable of preventing the crack from deforming continuously or narrowing the crack so as to prevent the crack from being produced again, but also has the advantages of being maintenance-free, low in construction cost, time-saving and labor-saving in construction and the like.

Description

technical field [0001] The invention relates to a method and structure for repairing cracks in building walls, and belongs to the technical field of crack construction in building structures. Background technique [0002] At present, in the field of architectural design technology, frame, shear wall or frame shear wall structures are often used. The gap between the infill wall built later and the concrete columns and walls poured first is often due to the thermal expansion and contraction of the material, and the swelling and dryness of the material. Inconsistent shrinkage caused by shrinkage conditions leads to wall cracking; in addition, in masonry structures, wall cracking is often caused by (blasting) vibration or uneven settlement of the foundation, which affects the appearance and function of the building.

Problems solved by technology

[0002] At present, in the field of architectural design technology, frame, shear wall or frame shear wall structures are often used. The gap between the infill wall built later and the concrete columns and walls poured first is often due to the thermal expansion and contraction of the material, and the swelling and dryness of the material. Inconsistent shrinkage caused by shrinkage conditions leads to wall cracking; in addition, in masonry structures, wall cracking is often caused by (blasting) vibration or uneven foundation settlement, which affects the appearance and function of the building.

In the prior art, the general repair method for this type of wall cracks is to seal and fill them up with cement mortar or putty powder. Although the existing method can temporarily seal and fill up the cracks, because the cracks are in the In the future, it will continue to develop under the alternating cycle of temperature and humidity in the four seasons. The existing repair method cannot fundamentally solve the problem. After a certain period of time, the cracks in the wall will still appear, and repeated repairs are required

Therefore, the existing method of repairing cracks in the building wall is still not ideal.
