Connecting structure of curtain wall keel

Abstract

The invention discloses a connecting structure of a curtain wall keel. The structure comprises a vertical keel, a transverse keel or two transverse keels are connected to one side or two sides simultaneously of the vertical keel through a connecting assembly, and each transverse keel is provided with a transverse internal expanding groove; and the connecting assembly comprises connecting members installed on the vertical keel, corresponding to each transverse keel, each connecting member is provided with a connecting part which can be inserted into the transverse internal expanding groove from the groove port of the transverse internal expanding groove, and each connecting part is inserted into the transverse internal expanding groove of the transverse keel and fixedly connected to the transverse keel through a first fastening assembly. The connecting structure of the curtain wall keel has the advantages of being convenient to install, labor-saving in installation, high in safety, high in connecting stability and reliability and the like.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a curtain wall keel connection structure. Background technique [0002] At present, the connection of horizontal and vertical keels in curtain walls on the market is mainly in two ways: splicing and welding. Among them, splicing is divided into two types: one is to install in sequence by unit, that is, install the first vertical keel first, and then install horizontal keels and vertical keels alternately on the side of the first vertical keel until the entire curtain wall is completed. The other is the post-installation method of the horizontal keel, that is, first install all the vertical keels of the curtain wall according to the set interval size, and then install the horizontal keel between the adjacent vertical keels. The disadvantage of the above-mentioned former installation method is that once the keel needs to be replaced due to errors or other factors ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing curtain wall technology for post-installation of transverse keel is not mature enough, and there are many defects as follows:

[0004] 1. It is difficult to hide the connectors and screws between the keels, and most of the connectors and screws are exposed, which not only affects the installation of the curtain wall panels, but also makes the appearance of the curtain wall after installation not simple and delicate;

[0005] 2. The number of connectors and screws required for the connection between the keels is large, resulting in difficulty in disassembly and assembly and low efficiency, and it is also necessary to open a large number of fastening installation holes on the keel, which will affect the strength of the keel and reduce it. Rust resistance of the keel

[0006] 3. The force transmission between the keel and the connector is directly fastened by screws. There are problems such as difficulty in guaranteeing the connection strength, easy loosening and failure, and low safety. Moreover, the screws are all connected to the side wall of the keel, and the force balance is stable. And poor stability, the side wall of the tubular keel is also easily deformed and damaged, which requires high wall thickness of the keel, increasing the weight of the keel and the overall cost
