Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass curtain wall fixing technology, specifically to a curtain wall fixing device. Background Technology
[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall structure with decorative effect commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system. It can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is an exterior building envelope or decorative structure that does not bear the load of the main structure. Existing curtain wall projects use curtain wall fixing devices for installation and fixation.
[0003] Chinese Patent No. CN223240912U discloses a curtain wall fixing device, belonging to the technical field of curtain wall fixing devices. It includes: a steel frame and a curtain wall fixing body. The front end of the steel frame has a pre-set insertion hole and a threaded hole. The front end of the curtain wall fixing body has an assembly groove, in which a sliding block is slidably connected. A connecting rod is installed at the rear end of the sliding block, and an insert is installed at the rear end of the connecting rod. The insert is adapted to the pre-set insertion hole. A bolt is installed at the front end of the sliding block, and the rear end of the bolt passes through the sliding block. A retaining ring is fitted on the outer wall of the bolt, and the retaining ring is located within the assembly groove. This curtain wall fixing device first positions the curtain wall fixing body on the front side of the steel frame by sliding the sliding block into the assembly groove, disengaging the insert from the insertion hole, aligning the insert with the pre-set insertion hole on the front side of the steel frame, and then rotating the bolt to extend it out of the threaded hole and into the threaded hole, thus fixing the curtain wall fixing body to the front side of the steel frame.
[0004] However, in the above technical solution, the sliding block is slid into the assembly slot to disengage the insert block from the insertion hole. The insert block is then aligned with the preset insertion hole on the front side of the steel frame and inserted to first position the curtain wall fixing body on the front side of the steel frame. Then, the bolt is rotated to extend out of the threaded hole two and into the threaded hole one, thus fixing the curtain wall fixing body on the front side of the steel frame. However, errors may occur during the machining of each hole. If errors occur, the position of the bolt and the positioning insert cannot be adjusted, which will cause it to mismatch with the preset slot and threaded hole. Secondary rework or on-site processing is required to make it work properly. Utility Model Content
