Technical Field

[0001] The utility model relates to the field of double-layer thermal insulation structures of exterior wall panels, in particular to a prefabricated double-layer thermal insulation structure of exterior wall panels. Background Art

[0002] Prefabricated wall panels are reinforced concrete plate-type components processed in prefabrication plants (yards) or construction sites for building assembly. They are referred to as wall panels or siding. Using prefabricated concrete wall panels to build 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] During the construction process, multiple wall panels need to be assembled in pairs to form a wall. During assembly, the relative positioning of the two wall panels must be maintained to ensure the overall appearance and strength of the wall. However, currently, prefabricated wall panels are generally simple square structures. During assembly, the two wall panels must be manually stacked and then adjusted in position, making the installation process complicated and affecting the construction efficiency of the wall panels. Furthermore, the internal insulation layer cannot achieve tongue-and-groove connections, making it unsuitable for use in "ultra-low energy buildings."

[0004] Therefore, it is necessary to invent a prefabricated exterior wall panel double-layer insulation structure to solve the above problems. Utility Model Content

[0008] Preferably, a third spring is bolted to the inner side of the inner cavity of the slide groove, and the other end of the third spring is bolted to the outer side of the slider, so that the slider is pushed to move toward the inner side of the slide groove by the elastic force of the third spring itself.
