[0002] In modern architecture, wall panels have become an indispensable building component. To improve construction efficiency, prefabricated walls are widely used. These walls draw on the principles of cast-in-place shear walls, using steel and other materials as a supporting framework and cast through a pouring process. With the rapid development of steel structures and the renewed emphasis on factory-based manufacturing and standardized assembly in construction, higher demands are being placed on walls for efficient thermal insulation, decorative properties, and seismic resistance. However, wall structures that are well-suited to these requirements and achieve integrated energy conservation and structural integrity are relatively scarce. Therefore, there is an urgent need to develop a new type of wall component that not only offers seismic resistance, efficient and long-lasting thermal insulation, and diverse decorative properties, but also allows for convenient prefabricated wall construction, thereby integrating architectural decoration, energy conservation, and enclosure functions, and streamlining the construction process.

[0039] Example 2:

[0040] See also Figure 1-8 The construction method of the assembled light steel keel composite wall panel in Example 1 of the present application is to assemble and connect the outer page panel, the vertical light steel keel frame, the thermal insulation and sound insulation layer, and the inner page panel in the following order. The specific steps are as follows:

[0041] S1.
