AI Technical Summary
Existing fully prefabricated exterior wall panel structures suffer from deformation differences between panels and between panels and the main structure, leading to joint cracking and leakage problems. Furthermore, traditional curtain wall materials have high thermal conductivity, making them prone to heat conduction and dissipation, or easily deformed during fires.
The building adopts a layered external enclosure structure. The inner layer uses ALC panels as the inner wall lining, and the outer layer uses integrated insulation and decoration panels. It is supported by a keel frame and uses hinged connections and sealing treatment to form an independent protection system.
It effectively avoids joint cracking and leakage, improves fire resistance and thermal insulation, while maintaining a high degree of industrial integration and simple assembly, adapting to the deformation of the building structure, and having a controllable overall thickness.

The second type is curtain wall, which is connected to the main body by hinge to avoid deformation difference and solve the problem of outer wall leakage. However, the curtain wall structure also has some defects in use, such as high thermal conductivity of glass curtain wall, easy heat conduction and heat dissipation, making it cold in winter and hot in summer, and metal keel is easy to deform in fire.
