Description

Technical Field

[0001] The utility model relates to the technical field of building exterior walls, in particular to an assembled exterior wall panel. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. Because they use standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrialized production methods. Most existing prefabricated houses use light steel skeletons as the main frame support, and prefabricated exterior wall panels are installed on the light steel skeleton through bolts and other connectors.

[0003] During installation of existing prefabricated exterior wall panel structures, there will be a large gap between two adjacent wall panels, and there is no corresponding structure to seal the gap, resulting in rainwater seeping into the interior of the building through the gap between the wall panels in rainy and snowy weather after construction is completed, and the waterproof performance is poor. In addition, the installation and fixing mechanisms of existing exterior wall panels are mostly arranged directly behind the wall panels. When installing and connecting the exterior wall panels to the keel frame, workers need to pass their hands around the two sides of the wall panels to install and fix the installation structure. In addition, the wall panels will also block the workers' line of sight, making it inconvenient for workers to position and construct the installation structure, and the installation efficiency is low.
