An internally connected curtain wall keel triple connection structure

Abstract

The invention discloses an intra-connection type curtain wall keel triple connection structure. The intra-connection type curtain wall keel triple connection structure comprises a vertical keel and two transverse keels connected to the two sides of the vertical keel through connection assemblies; the vertical keel is provided with a through mounting hole; the transverse keels are provided with transverse inner-expanded grooves; each connection assembly comprises a slide-connection part capable of penetrating through the through mounting hole and moving along the corresponding transverse inner-expanded groove; each slide-connection part is installed in the through mounting hole in a penetrating mode and is only in sliding fit with the through mounting hole; each slide-connection part is provided with two connection portions which are located in the transverse inner-expanded grooves of the two transverse keels and capable of rotating relative to the transverse inner-expanded grooves; and every two connection portions are fixedly connected with the two transverse keels through first fastening assemblies correspondingly. The intra-connection type curtain wall keel triple connection structure has the advantages of being easy and convenient to mount and dismount, high in connection strength, stability and reliability, low in cost, capable of advantageously improving appearance conciseness and refinement of a curtain wall, and the like.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an internal connection type curtain wall keel triple 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 replace...

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
