Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to dry-hanging structures. Background Technology

[0002] Curtain walls are exterior wall construction methods that use various strong, lightweight, and beautiful building materials to replace traditional brick or window wall combinations. They are exterior wall construction methods that surround the main structure to make the entire building beautiful, functional, and safe.

[0003] The existing curtain wall panels are installed on the keel frame by hanging.

[0004] Traditional keel frames are connected by welding. Because the keel frame structure is fixed after welding, it cannot achieve different detachable assembly and adjustment. Chinese patent CN207122081U discloses a dry-hanging structure and finishing system. The dry-hanging structure includes at least one first keel, at least one second keel, a connecting part for fixing the first keel to the wall, and a fastener for connecting the second keel to the finishing panel. The second keel is detachably connected to the first keel via a second fastener. After the finishing panel to be installed is fixed to the fastener, it is connected to the second keel to complete the installation of the finishing panel. Although this structure allows for on-site assembly, it cannot switch between different installation modes for the keel. Utility Model Content
