[0002] Steel structures offer advantages such as light weight, high strength, good seismic resistance, flexible layout, small component cross-sections, easy assembly, short construction periods, and large usable areas. They are also amenable to industrialized production and standardized manufacturing. Prefabricated steel-structured housing developed relatively early abroad and, due to its significant advantages, has now occupied a significant proportion of residential construction. A comprehensive and integrated residential industrialization system has been established. Based on actual projects, research has been conducted on the structural design, mix design and formulation technology, production process, and quality control of prefabricated sandwich insulated exterior wall panels for steel-structured housing. This has resulted in the development of lightweight prefabricated sandwich insulated exterior wall panels suitable for steel-structured housing and their application in actual steel-structured residential construction. The assembly of prefabricated sandwich insulated exterior wall panels (hereinafter referred to as exterior wall panels) in steel-structured buildings is an important indicator of building assembly efficiency, but many technical difficulties remain. Existing wall material specifications are not standardized, joints are not standardized, and on-site assembly efficiency is low. Furthermore, the assembly flexibility and stability of existing exterior wall panels between existing steel beams are limited, resulting in poor stability. Therefore, further improvements are needed.
