Technical Field

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. With the development of modern industrial technology, houses can be manufactured in batches, much like machine production. As a crucial component of prefabricated buildings, ensuring the lightweight, insulation, and decorative functions of exterior wall panels is of great significance. However, the technical defects and shortcomings of existing prefabricated exterior wall panels urgently need to be addressed; traditional prefabricated exterior wall panels are heavy, the insulation layer detaches, the decorative layer requires secondary construction, and the installation and connection efficiency is low, which restricts the improvement of the construction efficiency of prefabricated buildings and results in high construction costs. Furthermore, gaps often remain between the components of traditional prefabricated exterior wall panels. After the wall is assembled, these gaps may cause leaks, thus affecting the quality of the wall. Utility Model Content

The steel frame 2 is assembled by welding.

[0018] By adopting the above technical solution, the lightweight thermal insulation composite core material 3 is installed inside the crossbeam frame 21, so that the interior of the lightweight thermal insulation composite core material 3 is effectively pre-embedded with the conduit 20 and the tie piece 23, thereby ensuring the tightness between the steel frame 2 and the lightweight thermal insulation composite core material 3.

[0019] In this embodiment, the inner anti-crack steel mesh is fixed to one side surface of the steel frame 2 using self-tapping screws; In this embodiment, the decorative surface layer 1 is bonded to the outer side of the inner crack-resistant steel mesh membrane by the slurry of the lightweight thermal insulation composite core material 3; By adopting the above technical solution, the lightweight thermal insulation composite core material 3 uses surface slurry to adhere the decorative surface layer 1 to the outer side of the steel frame 2, thereby effectively ensuring a tight fit between the components.
