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

Embodiment 1

[0040] Such as Figure 1 to Figure 3 As shown, the internal triple connection structure of the curtain wall keel of this embodiment includes a vertical keel 1 and two horizontal keels 2 connected to both sides of the vertical keel 1 through a connecting assembly. The vertical keel 1 is provided with a through installation hole 10, The transverse keel 2 has a transverse inner expansion groove 21, and the connection assembly includes a sliding joint 3 that can pass through the through installation hole 10 and move along the transverse inner expansion groove 21. The sliding joint 3 is installed through the through installation hole 10 and can Rotating relative to the through installation hole 10, the sliding joint 3 has two connecting parts 31 that are respectively located in the transverse inner expansion grooves 21 of the two transverse keels 2 and only slide and fit with the transverse inner expansion grooves 21. The vertical keel 1 and the The sliding member 3 is fixedly conn...

Embodiment 2

[0046] The internal triple connection structure of the curtain wall keel of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as Figure 4 and Figure 5 As shown, the transverse keel 2 and the sliding joint 3 of this embodiment are also fixedly connected through the second fastening assembly, and the second fastening assembly is two fourth fastening screws 104, and each fourth fastening screw 104 is connected tightly at the same time. Fix the connecting part 31 of the holder 4 , the transverse keel 2 and the sliding joint 3 . Adding the second fastening component to connect the fastening transverse keel 2 and the sliding joint 3 can further improve the stability and reliability of the connection.

[0047] In this embodiment, the fourth fastening screw 104 is accommodated in the laterally expanded groove 21, the fourth fastening screw 104 is not exposed, and will not affect the installation of the curtain wall panel, and the curtain wa...

Embodiment 3

[0049] The internal triple connection structure of the curtain wall keel of this embodiment is basically the same as that of Embodiment 2, the main difference is that, as Figure 6 As shown, the vertical keel 1 of this embodiment does not have a vertically inwardly expanding groove 11, and the front of the vertical keel 1 is a plane. The first fastening component is a second fastening screw 102 , and the second fastening screw 102 is screwed and installed on the vertical keel 1 and presses the sliding joint 3 . The second fastening screw 102 in this embodiment does not perforate the sliding joint 3 , does not affect the strength of the sliding joint 3 , and the second fastening screw 102 is easier to install.

Abstract

The invention discloses an internal connecting type triple-connection structure of a curtain wall keel. The structure comprises a vertical keel and two transverse keels connected to the two sides of the vertical keel through a connecting assembly, a cut-through installing hole is formed in the vertical keel, and the transverse keels are provided with transverse internal expanding grooves; the connecting assembly comprises a sliding connecting member which can penetrate through the cut-through installing hole and move along the transverse internal expanding grooves, and the sliding connecting member is installed in the cut-through installing hole in a penetrating mode and can rotate relative to the cut-through installing hole; and the sliding connecting member has two connecting parts which are located in the transverse internal expanding grooves of the two transverse keels correspondingly and only matched with the transverse internal expanding grooves in a sliding mode, and the vertical keel is fixedly connected to the sliding connecting member through a first fastening assembly. The internal connecting type triple-connection structure of the curtain wall keel has the advantages of being easy to assemble and disassemble, high in connection strength, high in stability and reliability, low in cost, beneficial to enhancing conciseness and exquisiteness of the appearance of the curtain wall 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...
