Description

Technical Field

[0001] This invention relates to the field of prefabricated building wall panel technology, specifically to a convenient prefabricated building wall panel connection device. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they are representative of modern industrialized production methods.

[0003] When installing prefabricated building wall panels, installers need to connect and fix them using nail guns or screws. Currently, during the connection and installation of prefabricated building wall panels, installers need to support the wall panels to prevent deviations that could lead to large gaps between the panels. However, because the wall panels are relatively thick and heavy, it is quite strenuous for installers to support them. When the gaps between the wall panels are large, multiple installers need to push the wall panels to make them contact each other. The wall panels are prone to tilting during movement. When a wall panel tilts, it needs to be supported in time, otherwise it will tip over and cause damage. Summary of the Invention
