  • Publication number: 20250137252
    Abstract: The present application relates to the technical field of building walls and provides a composite wall being lightweight, easy to be prefabricated and convenient for on-site construction. By making the composite wall such that a decorative layer and a formwork are overhung on both sides of a core concrete layer, it is formed a structure similar to a core-wall and steel structure that has rigidity and is elastically deformable. A thermal insulation layer is filled between the decorative layer and the core concrete layer which are connected by a precast outer cantilever rod. The amount of concrete in the prefabricated part of the composite wall is greatly reduced. The composite wall does not require flipping in the prefabrication process and has a significantly shortened production cycle.
