Description

Technical Field

[0001] This utility model relates to the technical field of crack repair tools, specifically a portable building crack repair tool. Background Technology

[0002] Various adhesive materials can be used to repair building cracks, with the specific choice depending on the size and location of the crack. These include: Epoxy Resin Adhesive: Epoxy resin adhesives exhibit superior performance in treating concrete cracks, especially when extremely strong adhesion is required. After curing, it forms a protective layer, preventing moisture and chloride ion intrusion, and is suitable for repairing micro-cracks (less than 0.1mm wide). Epoxy resin adhesives have high strength, cure quickly, and restore the overall performance of the concrete. Crack Filler: Crack filler is a relatively elastic repair material suitable for larger wall cracks. It has strong adhesion and effectively prevents crack widening and leakage. The method of application is to first clean the crack, then fill the entire crack with crack filler, smooth and compact it with a scraper, and apply a second coat after it dries. Cement Mortar: Cement mortar is a commonly used heavy-duty repair material suitable for larger cracks and wall structure repairs. The method of application is to first clean the crack, then mix cement mortar evenly, fill the crack with a scraper, compact it with a trowel, and apply a second coat after it dries. Fiberglass cloth: Fiberglass cloth is suitable for repairing larger cracks, possessing good toughness and tensile strength. The method of application is to first clean the crack, then apply wall paint or sealant to the wall surface, attach the fiberglass cloth to the crack, press it firmly with a blade or scraper, and apply a second coat after it dries. Polymer-modified cement: This material has good adhesion and elasticity, effectively filling micro-cracks and preventing moisture penetration, reducing the risk of later corrosion. It is suitable for repairing various types of concrete cracks. Waterproof coatings and rust inhibitors: For concrete cracks corroded by chloride ions, specialized waterproof coatings can be used to seal the cracks and prevent liquid penetration. Simultaneously, repair materials with added rust inhibitors can effectively inhibit steel reinforcement corrosion, ensuring the long-term safety of the concrete structure.

[0003] When using glue to repair cracks, a glue gun is needed to squeeze the glue out. However, when the glue cartridge is placed on the glue gun, the glue is not restrained around its edges during the squeezing process, so the glue tends to spread outwards and lacks the penetrating power to enter the crack. Therefore, when the crack is deep, it is impossible to squeeze the glue to the deepest part of the crack. Utility Model Content
