[0002] At present, the common aluminum alloy skeleton curtain wall beam connection forms in the domestic curtain wall industry are mainly divided into angle piece connection and pin connection. Among them, the beam structure is divided into open-cavity beam and closed-cavity beam. The open-cavity beam is easy to construct but its structural stress is poor and the amount of profile used is large. The closed-cavity beam uses less material and has better structural stress, but its construction is more difficult. The closed-cavity beam often needs to be connected to the column during installation. The traditional connection method is more complicated and the connection effect is poor.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-3As shown, the present invention provides a curtain wall closed-cavity beam 2 connection structure, comprising: a column 1, a beam 2, two sets of support blocks 3, and a threaded rod 4. A plurality of first connection holes 100 are provided on the side of the column 1, the beam 2 is passed through front to back, and a second connection hole 200 is provided on one side of the beam 2. Two support blocks 3 are respectively provided at both ends of one side inside the beam 2. A plurality of connection columns 300 are provided on the side of the support block 3 close to the column 1. The connection columns 300 can enter the first connection holes 100. Threaded through holes 310 are respectively provided on the two support blocks 3. The threaded rod 4 passes through the two threaded through holes 310, and one end extends out of the beam 2 through the second connection hole 200. Rotating the threaded rod 4 can clamp the connection column 300 in the first connection hole 100. Preferably, the upper and lower ends of the support blocks 3 contact the inner opposite side walls of the beam 2. By rotating the threaded rod 4 outside the crossbeam 2, the two support blocks 3 are brought closer together, allowing the connecting column 300 to fit tightly into the first connecting hole 100 of the column 1. The support blocks 3 not only assist in connecting the crossbeam 2 to the column 1, but also provide support from within the crossbeam 2, reducing deformation of the crossbeam 2. By reversely twisting the threaded rod 4, the crossbeam 2 and column 1 can be disconnected, facilitating assembly and disassembly of the crossbeam 2 and increasing the adaptability of the device.

[0021] In this embodiment, a rotating plate 400 is fixed to one end of the threaded rod 4 extending beyond the crossbeam 2. The rotating plate 400 is provided with a cross-shaped notch 401. The upper surface of the rotating plate 400 is flush with the side of the crossbeam 2. The arrangement of the rotating plate 400 facilitates the operator to insert a screwdriver into the cross-shaped notch 401 for tightening, facilitating operation and saving manpower. Furthermore, the flushness of the rotating plate 400 with the side of the crossbeam 2 further enhances the aesthetics of the crossbeam 2.

[0022] In this embodiment, a slot 301 is provided on the outer surface of the connecting column 300, and the side wall of the first connecting hole 100 can contact the slot 301. Figure 2-3 As shown, a slot 301 is provided on the outer surface of the connecting column 300. When the two support blocks 3 are close to each other, the slot 301 of the connecting column 300 can be stuck on the side wall of the first connecting hole 100 of the column 1. When subjected to horizontal force, the column 1 and the beam 2 are not easily separated. Preferably, the width of the slot 301 of the connecting column 300 is equal to the thickness of the side wall of the column 1, so that the connection between the column 1 and the beam 2 is not easily shaken in the horizontal direction.

[0023] In this embodiment, the crossbeam 2 is preferably made of aluminum alloy, which is easy to obtain. The support block 3 is made of metal, preferably a steel structure. A support block 3 that can be supported in the crossbeam 2 is cut out from the steel plate, and a threaded hole is set on the support block 3. At the same time, a connecting column 300 is welded on the support block 3. After the support block 3 is made, a second connecting hole 200 corresponding to the threaded hole is opened on the crossbeam 2, and the corresponding position of the connecting column 300 is preferably determined on the column 1, and then a first connecting hole 100 is opened on the column 1.
