An internal connection triple connection structure of curtain wall keel

Abstract

The invention discloses an internal-connected triple-connected connection structure for a curtain wall keel. The connection structure comprises a vertical keel and two transverse keels connected with the two sides of the vertical keel through connection assemblies, wherein the vertical keel is provided with a through installation hole, the transverse keels are provided with transverse internal expansion grooves, and the connection assemblies comprise sliding and connection pieces capable of penetrating through the through installation hole and moving along the transverse internal expansion grooves; the sliding and connection pieces are installed in the through installation hole in a penetrating mode, and can rotate relative to the through installation hole; and each sliding and connection piece is provided with two connection parts, wherein the two connection parts are respectively located in the transverse internal expansion grooves of the two transverse keels and can rotate relative to the transverse internal expansion grooves, the vertical keel and the sliding and connection pieces are fixedly connected through first fastening assemblies, and the transverse keels and the sliding and connection pieces are fixedly connected through second fastening assemblies. The internal-connected triple-connected connection structure for the curtain wall keel has the advantages of being simple and convenient to disassemble and install, high in connection strength, high in stability and reliability, beneficial to improvement 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 internal triple connection structure of a curtain wall keel. 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 er...

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 low efficiency, and a large number of fastening installation holes need to be opened on the keel, which has a great impact on the strength 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
