Description

Technical Field

[0001] The utility model relates to the technical field of building exterior wall hanging plates, in particular to a building exterior wall hanging plate connection structure. Background Art

[0002] At present, thermal insulation and decoration in building envelope structures have become one of the research directions in the field of building energy conservation, and internal insulation technology has been gradually replaced by external wall insulation technology. The external wall insulation system is a thermal insulation system installed on the surface of the building's exterior wall. The environmental conditions are complex and the weather resistance requirements are high, which puts forward high requirements on the quality and life of the external wall insulation system. To ensure excellent quality and long life, the external insulation system must be firmly and reliably connected to the exterior wall surface and cannot be loose or fall off; the external surface of the external insulation system must be complete and solid and cannot crack, seep, or peel or delaminate. Due to fierce market competition, as well as the huge differences in the quality of chemical building materials and polymer mortars and the huge differences in construction quality and technology, the quality and life of the external wall insulation system are difficult to be effectively controlled and guaranteed. The loosening and falling of insulation boards and the cracking and peeling of the surface layer occur from time to time, which seriously affects the effective implementation of building energy conservation work. At the same time, there are many kinds of exterior wall finishing materials, and a considerable number of designers choose heavy finishing materials such as tiles, which put forward more stringent and complex requirements on the external wall insulation structure.

[0003] In response to the above problems, the inventor disclosed an assembled thermal insulation and decorative integrated exterior wall panel in CN201721748832.7. As an industrialized large-format external thermal insulation wall panel, the exterior wall panel integrates the exterior wall thermal insulation function and the exterior wall decoration function, meeting the needs of building energy conservation and architectural decoration. The exterior wall panel is provided with L-shaped upper and lower connecting parts, and adjacent exterior wall panels are fixed by mutually staggered upper and lower connecting parts. However, after long-term construction and use, the inventor found that the connection structure of the exterior wall hanging panel in this technical solution is relatively complicated, and the upper and lower connecting parts need to be separately connected and fixed. The construction steps are relatively cumbersome and the labor cost is high. Utility Model Content
