Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a steel skeleton light exterior wall panel. Background Art

[0002] In the prior art, with the continuous development of the housing construction industry, traditional block masonry materials have gradually been transformed into panels, which can be divided into prefabricated composite wall panels and on-site cast-in-place wall panels. The prefabricated composite wall panel means that the wall panel is made into a finished product in the factory and transported to the construction site for assembly. This kind of wall panel can solve the disadvantage of complex wall construction and can shorten the construction period. However, the existing prefabricated composite wall panels have the following problems: the connection nodes between the exterior wall panel units and the structural beam are exposed, which affects the later ceiling decoration. The splicing and sealing effect between the exterior wall panel units is not good. After the wall expands and contracts due to thermal expansion and contraction, it is not convenient to deal with later.
