[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 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., and are representatives of modern industrialized production methods because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications. Prefabricated components have high requirements for construction accuracy. Since prefabricated buildings require the prefabrication of a variety of different prefabricated components, their production speed is slow, and during the construction process, there may be problems of mismatch or conflict between different prefabricated components, which affects the construction quality and slows down the progress of construction.
