Background Art

With the implementation of the "dual carbon" goals, energy conservation and emission reduction in the construction industry, green buildings are imminent, and prefabricated buildings are also regarded as a key industry for national sustainable development. The existing prefabricated wall panels mainly include ALC panels, light steel keel wall panels, and concrete prefabricated exterior wall panels, but the above wall panels all have problems such as heavy weight, many joints, large thermal bridges, poor air tightness and waterproofness, and poor wall panel integrity. At the same time, after the wall panels are installed, an insulation layer needs to be pasted on the exterior of the wall, and the process is complicated. Therefore, a utility model patent with patent number CN219671840U appeared, which discloses an assembled insulation integrated steel frame wall panel, including cylindrical columns arranged in pairs longitudinally, cylindrical connecting columns arranged horizontally between the columns, connecting pieces are arranged between the columns arranged in pairs, and the connecting pieces, columns and connecting columns are fixed to each other to form a skeleton structure, and filling materials are arranged inside the skeleton structure, and a covering layer is arranged on the outer side of the filling material.
