[0002] Prefabricated exterior wall panels refer to reinforced concrete plate-type components that are processed in prefabrication plants (yards) or construction sites for building assembly, referred to as wall panels or sidings. The use of prefabricated concrete wall panels to construct prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period.

[0003] At present, in order to reduce the construction period and ensure the strength of the factory building, most factories generally use steel frame structures to quickly build the overall frame of the factory, and then use prefabricated exterior wall panels to assemble the overall exterior wall to form a complete building. Utility Model Content
