Inner-connected curtain wall keel two-joint connection structure

Abstract

The invention discloses an internal-connected curtain wall keel two-connected connection structure. The construction structure comprises vertical keels and transverse keels connected with one sides of the vertical keels through connection assemblies; the vertical keels are provided with more than one plug holes, the transverse keels are provided with transverse internal expansion grooves, and the connection assemblies comprise sliding connection pieces located in the transverse internal expansion grooves and only matched with the transverse internal expansion grooves in a sliding mode; the position, corresponding to each plug hole, of the sliding connection pieces is provided with a plug part inserted into plug holes; and the vertical keels and the siding connection pieces are fixedly connected through first fastening assemblies. The internal-connected curtain wall keel two-connected connection structure has the advantages of being simple and convenient to disassemble and install, high in connection strength, high in stability and reliability, low in cost, beneficial to improvement of the conciseness and refinement of the curtain wall appearance and the like.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an inwardly connected curtain wall keel double 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 ...

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
