[0002] Building exterior walls are the walls that run along the four edges of a building and are in direct contact with the outdoor air. They serve to maintain the main structure of the building, provide sound insulation and heat preservation, and bear loads. Currently, most building exterior walls are prefabricated structures that are then transported to the construction site for assembly and installation.

[0003] Chinese Patent Publication No. CN216689891U discloses a prefabricated building exterior wall structure, relating to the technical field of building exterior walls. It addresses the problem that most existing building exterior wall assembly components are complex, time-consuming, labor-intensive, and inefficient during assembly. The proposed structure includes a ground-embedded fixing base, comprising an embedded plate, an embedded track above the plate, and slots above the track into which multiple sets of exterior wall bodies are inserted. This application incorporates assembly components between the exterior wall bodies, allowing for splicing. These components improve the ease of assembly. After installation, the gaps between the exterior wall bodies are filled with a sealing layer for reinforcement. The structure is simple and compact, effectively improving the ease of assembling building exterior walls.

[0004] Most existing technical solutions have the following drawbacks: the overall prefabricated effect is poor, and the joints are fixed protruding structures, which are not convenient for disassembly and can easily affect subsequent installation. Therefore, this utility model provides a prefabricated building exterior wall to solve the above-mentioned problems. Utility Model Content
