Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a crack repair device for building construction. Background Art

[0002] During the process of building construction, cracks sometimes appear on the walls of the house. The appearance of cracks is mainly caused by reasons such as temperature difference, uneven settlement, and vibration. Cracks affect the overall beauty of the house and reduce the waterproof, moisture-proof, heat-insulating and other properties of the house.

[0003] The Chinese utility model patent with the patent number CN219604941U discloses a crack repair device for building construction, including: a material cylinder, a slurry outlet is connected and communicated at the bottom of the material cylinder, and support plates are vertically arranged in parallel on both sides of the material cylinder. The injection mechanism has: a pressure component and a movable component. The pressure component is arranged on the top of the material cylinder and partially extends into the material cylinder. The movable components are symmetrically fixed on both sides of the pressure component and are slidably matched with the support plates on both sides. By grasping the movable components with both hands and pressing them down along the support plates, the power rod drives the connecting seat to drive the second connecting block to move towards the material cylinder, thereby driving the extrusion piston to extrude the slurry in the material cylinder towards the slurry outlet, facilitating the slurry to spray out smoothly from the slurry outlet. After releasing the power component, the elastic return of the return spring drives the extrusion piston to reset, facilitating subsequent extrusion of the slurry flowing into the material cylinder again.

[0004] During the actual use process, when encountering deeper cracks, it is not easy for the slurry to fill the cracks completely, and there are cavities in the cracks, reducing the waterproof, moisture-proof, heat-insulating and other properties of the house. Utility Model Content
