Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a fixing structure of an assembled exterior wall panel. Background Art

[0002] Prefabricated exterior wall panels are a type of wall system widely used in the construction industry. They refer to a type of wall that is prefabricated, processed, and packaged in sections in a factory and then installed on site. Specifically, this type of exterior wall panel includes exterior wall covering materials, thermal insulation layers, heat insulation layers, and other required accessories.

[0003] At present, the connection methods between external wall panels and main structures mainly include pure hanging connection and pure pre-embedded connection steel bar cast concrete connection. Pure hanging connection is to connect the metal hanging parts pre-installed on the wall panels and the main structure; pre-embedded connection steel bar cast concrete connection is to set pre-embedded steel bars along the external wall panels, and then use concrete to cast the connecting steel bar parts as a whole. However, this overall casting has poor load-bearing capacity and is inconvenient to install. Utility Model Content

[0013] 1. The handle can drive the rotating shaft to rotate, and the rotating shaft can simultaneously drive the two-way screws at both ends to rotate, so that the two H-shaped plates can be driven to slide relatively on the limit frame through the two two-way screws, so that the semicircular rings at the ends of the H-shaped plates can be driven to approach each other.

[0014] 2. When the driving shaft 1 rotates, the worm will be driven to rotate synchronously, and the worm can be used to drive the worm wheel on one side to rotate, so as to drive the shaft 2 and the winding wheel to rotate, and then the winding wheel will wind up the two connecting ropes, so that the two connecting ropes can be driven by the ends of the two connecting ropes to move relative to each other, and the connecting plates and the connecting blocks on the fixing columns are connected and fixed, so that the external wall panels can be clamped and sleeved through the fixed structure, and at the same time, they can be connected to the steel beam frame of the main structure, thereby improving the installation efficiency of the wall panels and enhancing the load-bearing performance of the wall panels.

[0015] 3. After the wall panel is fixedly installed, the buffer plate can be used to abut against the outer wall of the wall panel. The buffer plate can be squeezed by the extrusion spring arranged in the sleeve. When the wall panel is impacted, the buffer plate can be used for buffering and shock absorption, thereby protecting the wall panel. BRIEF DESCRIPTION OF THE DRAWINGS
