[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 have become a representative of modern industrialized production methods due to their use of standardized design, factory production, and assembly construction. They are also one of the ways to achieve construction industry upgrades, green development, and a low-carbon economy.

[0003] In existing prefabricated buildings, composite panels have been widely used in engineering projects. However, the existing composite panel construction method generally involves prefabricating the lower part of the composite panel (i.e., the prefabricated panel) in the factory, transporting it to the construction site, setting up formwork and support, hoisting the prefabricated panel, laying the upper part of the composite panel steel bars, and pouring the upper concrete. After the upper concrete is cured to meet the requirements, the formwork and support are removed to form an integral composite panel. That is, the existing composite panel construction method has many processes, a long construction time, and requires a large number of construction formwork and support, and the project cost is high.
