Processing method for masonry wall crack

Abstract

The invention discloses a processing method for a masonry wall crack. The processing method comprises the steps that plaster layers on the two sides of the masonry wall crack are shoveled away along the masonry wall crack until a masonry wall is exposed; a plurality of V-shaped grooves are cut along the masonry wall crack, the V-shaped grooves are perpendicular to the crack, and positioning holesare drilled at the two ends of each V-shaped groove, so that U-shaped tie bars are inserted into the positioning holes; cement paste is poured into the positioning holes at the two ends of each V-shaped groove, the bending parts on the two sides of each U-shaped tie bar are inserted into the corresponding positioning holes on the two sides of the crack, so that anchoring is formed between the parts, inserted into the holes, of the U-shaped tie bars and the cement paste, the U-shaped tie bar bodies are buried into the V-shaped grooves, the crack is mended with mortar in a embedded mode, the V-shaped grooves are covered with the mortar, and primary trowelling is conducted; hardware cloth is laid along the crack range, so that the whole masonry wall crack is covered, and after leveling is conducted with cement plaster, mending parts are trowelled with latex putty till to be as level as an original wall surface. According to the processing method for the masonry wall crack, it is achievedthat the crack is mended, and the development of the crack is suppressed to some extent.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for treating cracks in masonry walls. Background technique [0002] Cracks mainly include concrete wall cracks and masonry wall cracks. The cracks on the masonry wall are mainly caused by uneven foundation settlement, temperature changes, etc., and some are caused by external forces, such as sledgehammers smashing the wall. This kind of cracking is not only the cracking of the plastering layer, but also the masonry of the inner wall. [0003] To deal with such cracks in the existing construction process, the surface layer around the cracks is generally removed first, the mortar is filled, and then the cloth is pasted, and the surface layer is troweled and repaired. This method is effective for smaller and shallower wall cracks, but for deeper and longer wall cracks, this method is only effective for a short period of time after using this method, and new ...

However, we cannot judge when the changes in the previous period tend to be flat. Due to the needs of construction, after cracks are often found, crack treatment needs to be carried out in a short period of time.
