[0002] Prefabricated buildings are a systematic project, and their main development goals are to improve building quality, speed up production rates, save resources, reduce environmental pollution and achieve sustainable development of buildings. Sandwich panels are composed of two layers of formed metal panels (or other material panels) and a polymer insulation core that is foamed and matured directly in the middle of the panels. Because of its unique composition structure, sandwich panels have natural advantages such as light weight, high strength, rigidity, thermal insulation, and easy assembly on the construction site. In the sandwich panels of the prior art, the materials of the sandwich layer are formed by cotton or foam, which leads to insufficient support of the sandwich layer and easy deformation.
