Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, in particular to an external curtain wall connection structure. Background Art

[0002] The exterior curtain wall is the outer wall enclosure of the building. It does not bear weight. It is hung on the outer surface of the building like a curtain. It is a lightweight wall with decorative effect, so it is also called "curtain wall". Usually, the keel is first assembled to the wall through some fasteners or embedded parts, and then the exterior curtain wall and the keel are assembled through fasteners such as bolts or self-tapping screws. When the exterior curtain wall is actually installed, due to the assembly error during the installation of the keel, the position of the exterior curtain wall on the keel needs to be fine-tuned to keep the various curtain wall panels flush. The existing technology generally involves workers manually adjusting the hoisted exterior curtain wall and then fixing the exterior curtain wall. The exterior curtain wall is generally large in size, which consumes a lot of physical strength of the workers, and the manual adjustment precision is low, and the work efficiency is not high.
