Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, specifically a device for preventing and repairing cracks in precast concrete components for building engineering. Background Technology

[0002] Cracks in precast concrete components are physical structural changes caused by internal and external factors. Cracks are a major cause of reduced load-bearing capacity, durability, and waterproofing of concrete structures. If the cracks are not particularly severe and only cause leakage, a caulking method can be used. A V-shaped groove is chiseled along the crack, debris is removed, and the area is rinsed clean with water. Next, a layer of waterproofing solution is applied to the surface of the crack for repair.

[0003] In the process of repairing cracks in precast concrete components, the adhesive is applied manually to the cracks using a brush. This method is not only labor-intensive but also inefficient, making it unsuitable for the rapid repair of large numbers of cracks. To address these issues, this application proposes a device for preventing and repairing cracks in precast concrete components for building construction. Utility Model Content
