Description

Technical Field

[0001] The utility model relates to the technical field of building exterior protective structure engineering, in particular to a dry-hanging unit curtain wall. Background Art

[0002] Dry-hang unitized curtain walls are curtain wall panels (such as glass or stone) fixed to primary and secondary studs via connectors, which are in turn connected to the main building structure. Construction methods typically include frame systems, integral unitized systems, and semi-unitized systems, with the integral unitized system being the primary form of dry-hang unitized curtain walls.

[0003] For example, the utility model patent with publication number CN216552577U discloses a dry-hanging stone curtain wall, which includes a curtain wall unit, wherein the curtain wall unit includes a stone slab, a connecting assembly and a secondary keel; the connecting assembly includes a hook and a hanging member, the hook is connected to the stone slab, and the hanging member is connected to the secondary keel; the hook includes a first body and two hooks with downward openings arranged on the first body in the upper and lower parts, and the hanging member includes a second body and two hooks with upward openings arranged on the second body in the upper and lower parts, and the hooks cooperate with each other; each curtain wall unit includes four connecting assemblies, and the hooks of the four connecting assemblies are distributed in a rectangular shape on one side of the stone slab. This new dry-hanging stone curtain wall is simple to install, has high construction efficiency, and is firmly installed. However, there is a problem in the fastening and installation of the hanging parts and the fasteners when installing them through the hanging parts and the fasteners, which will cause mutual sliding between the hanging parts and the fasteners, and finally lead to unstable installation of the curtain wall unit. The stone slabs after installation will be offset parallel to the external main keel. For this reason, we propose a dry-hanging unit curtain wall. Summary of the Invention
