Description

Technical Field

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

[0002] The curtain wall is the exterior wall enclosure of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability of itself, and is an exterior protective structure or decorative structure of the building that does not bear the effect of the main structure (the exterior wall frame support system is also a type of curtain wall system). Common curtain wall structures usually use glass materials, which are mainly divided into hidden frame, semi-hidden frame, exposed frame, point type, full glass and other structural forms. Curtain walls have the advantages of light structure, flexible design, systematic construction, and easy replacement and maintenance.

[0003] The installation of the glass curtain wall first involves installing curtain wall connectors, and then snapping the left and right ends of the glass curtain wall into the curtain wall connectors. Curtain wall connectors are usually made of steel and aluminum alloy structures. Most of the existing curtain wall connectors are connected to each other in the form of snap-fitting, with fewer snap-fitting points, resulting in lower connection stability. When impacted, the glass curtain wall is easily detached from the connector, resulting in lower safety performance. It is necessary to design a building curtain wall connection structure to solve the above-mentioned problems. Utility Model Content
