[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrialized production methods.
