Embodiment 1
[0037] Such as Figure 1 to Figure 3 As shown, the curtain wall keel internal connection type double connection structure of this embodiment includes a vertical keel 1 and a horizontal keel 2 connected to one side of the vertical keel 1 through a connecting component. The horizontal keel 2 has a laterally expanded groove 21, and the connecting component It includes a connecting piece 3 that is located in the transverse inner expansion groove 21 and can move along the transverse inner expansion groove 21. The connecting piece 3 has an insertion part 31 that is inserted into the vertical keel 1 and only slides with the vertical keel 1. The horizontal keel 2 It is fixedly connected with the connecting piece 3 through the first fastening component. The vertical keel 1 of this embodiment is provided with an insertion hole 10, the insertion hole 10 is a rectangular hole, the connector 3 is a rectangular pipe, one end of which is inserted into the rectangular hole as the insertion pa...
Embodiment 2
[0042] The curtain wall keel internal connection double connection structure of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as Figure 4 As shown, the first fastening component in this embodiment is a second fastening screw 102 , and the second fastening screw 102 is threadedly mounted on the connecting member 3 and compresses the transverse keel 2 .
[0043] The second fastening screw 102 of this embodiment does not perforate the transverse keel 2 , which can reduce the impact on the strength of the transverse keel 2 , improve the anti-rust ability of the transverse keel 2 , and the installation difficulty of the second fastening screw 102 is small.
Embodiment 3
[0045] The curtain wall keel internal connection double connection structure of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as Figure 5 As shown, the present embodiment is also provided with a supporting member 4 for supporting the curtain wall panel to facilitate the installation of the curtain wall panel. The supporting member 4 is fixedly connected with the transverse keel 2 and the connecting member 3 through the first fastening assembly, specifically, The first fastening screw 101 simultaneously connects the fastening holder 4 , the connecting piece 3 and the transverse keel 2 .
[0046] The first fastening screw 101 of this embodiment simultaneously connects the fastening holder 4 , the connecting piece 3 and the transverse keel 2 , which can save the number of fasteners, reduce costs and simplify installation. In other embodiments, the supporting part 4 can also be connected with the connecting part 3 as one piece, or the...
