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. The connection strength between the horizontal keel and the vertical keel is poor, and even cannot meet the strength requirements of the curtain wall, especially when the connection stress points of the horizontal keel are concentrated on the side wall on one side, the shear and torsion resistance of the horizontal keel will be greatly reduced. Cause connection strength and stability to decline, and even fail to meet the strength requirements of the curtain wall
[0005] 2. The connectors and screws between the keels are difficult to hide, 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 exquisite, and is easy to rust, reducing the service life of the curtain wall

Embodiment 1

[0030] Such as Figure 1 to Figure 6 As shown, the curtain wall keel connection structure for post-installation of the horizontal keel in this embodiment includes two vertical keels 1 and a horizontal keel 2 installed between the two vertical keels 1, and the horizontal keel 2 is a circumferentially closed tubular profile , each vertical keel 1 is connected with a shear connection assembly located in the inner cavity of the horizontal keel 2 and supports the horizontal keel 2, the shear connection assembly includes an inner connecting piece 3 fixedly installed in the inner cavity of the horizontal keel 2, and the inner connecting piece 3 An open slot 31 with an open end is provided, and more than one supporting member 4 that can be inserted into the open slot 31 from the opening of the open slot 31 is installed on the vertical keel 1, and each supporting member 4 is located in the open slot 31 and holds the inside of the opening slot 31. The connector 3 and the end of the tran...

Embodiment 2

[0038] The curtain wall keel connection structure used for the post-installation of the transverse keel in this embodiment is basically the same as in Embodiment 1, the main difference is that, as Figure 7 and Figure 8 As shown, in this embodiment, the supporting part 4 is provided with a limiting part 41 that prevents the inner connecting part 3 and the vertical keel 1 from moving away from each other, and the limiting part 41 functions to limit the maximum distance between the horizontal keel 2 and the vertical keel 1 As a result, the limiting portion 41 abuts against the end of the inner connecting member 3 away from the vertical keel 1 .

[0039] Moreover, in the present embodiment, the transverse keel 2 is provided with a transverse inner expansion groove 23, and the transverse inner expansion groove 23 includes a bottom groove body and a top groove body, and the maximum width of the bottom groove body is greater than the maximum width of the bottom groove body, so that...

Abstract

A curtain wall keel connecting structure for after-mounting a transverse keel comprises two vertical keels and the transverse keel after-mounted between the two vertical keels. The transverse keel isa tubular profile which is circumferentially and annularly closed, at least one vertical keel is connected with a shear resistant connecting assembly located in an inner cavity of the transverse keeland supporting the transverse keel, and the shear resistant connecting assembly comprises an inner connecting piece fixedly mounted in the inner cavity of the transverse keel; the inner connecting piece is provided with an opening groove with one end being open, more than one supporting parts capable of being arranged in the opening groove from an opening of the opening groove are mounted on eachvertical keel, and the supporting parts are located in the opening groove to support the inner connecting piece; and a gap allowing the supporting parts to enter the opening groove is formed in the end of the transverse keel, and the curtain wall keel connecting structure further comprises a retreat preventing assembly for preventing the inner connecting piece from breaking away from the opening groove. The curtain wall keel connecting structure for after-mounting the transverse keel has the advantages that the structure is simple, manufacturing is easy, the cost is low, mounting is simple andconvenient, and the shear resistant capability and the connecting stability are good.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a curtain wall keel connection structure for post-installation of transverse keels. 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 b...
