[0036] It should be noted that the opening of the engaging slot faces the suspended end of the horizontal frame 5 .

[0037] In this embodiment, a clamping groove is formed by setting a clamping plate 7 on the horizontal frame 5 to cooperate with the periphery of the first flange plate for clamping. During installation, it is only necessary to clamp the first flange plate on the side of the suspended end away from the horizontal frame 5 through the clamping groove, and then cooperate with the support member 6 to support the side of the web plate close to the suspended end of the horizontal frame 5, that is, the clamping groove and the support member 6 are respectively located on both sides of the web plate, which improves its stability during fixation, facilitates installation and disassembly, and improves construction efficiency. Compared with the welding connection method, it is more convenient for turnover use.

[0043] In this embodiment, when connecting the clamping member 9, it can first be clamped on the periphery of the second flange plate through the clamping groove 94 on the clamping portion 91, and then the fixing bolts 93 are tightened to make it abut against the surface of the second flange plate for fixation, which is convenient for installation and disassembly. At the same time, the second connecting plate 92 on the clamping portion 91 is bolted to the support member 6 through the second opening to complete the connection of the clamping member 9, which is convenient for installation and disassembly, as well as for turnover use.

[0044] On the basis of the above embodiment, in a preferred embodiment, as Figures 2 to 5 As shown, two fixing plates 10 are provided at intervals on the top of the horizontal frame 5 along its length direction, and are used to limit the horizontal channel 1 through the fixing plates 10 .

[0045] It should be noted that the width between the two fixing plates 10 is adapted to the width of the horizontal channel 1 .

[0046] In this embodiment, by setting two fixing plates 10 on the horizontal frame 5, when the horizontal channel 1 is placed, the horizontal channel 1 can be clamped between the two fixing plates 10, which is convenient for positioning and installation. At the same time, it plays a limiting role during the construction process, avoiding the horizontal channel 1 from being offset, improving safety performance, and reducing welding operations.

[0047] On the basis of the above embodiment, in a preferred embodiment, as Figures 2 to 5 As shown, the fixing plate 10 is provided with a third opening for bolt connection with the horizontal channel 1 .

[0048] In this embodiment, the horizontal channel 1 is fixed by providing a third opening on the fixing plate 10 and connecting it to the horizontal channel 1 with bolts, thereby ensuring safety performance.

[0049] On the basis of the above embodiment, in a preferred embodiment, as Figures 2 to 4 As shown, a plurality of lifting ears 11 are provided on the top of the horizontal frame 5 .

[0050] Specifically, if Figure 4As shown, the horizontal frame 5 includes a first frame and a second frame arranged in sequence along the horizontal direction. The first frame and the second frame are staggered in the vertical direction from bottom to top, and the first frame and the second frame are connected by connecting plate bolts; a first rib is provided on the top of the first frame, and the first rib is connected to the connecting plate; a second rib is provided on the bottom of the second frame, and the second rib is connected to the connecting plate. In this embodiment, by dividing the horizontal frame into a first frame and a second frame and connecting them by connecting plates, the first frame and the second frame are staggered in the vertical direction, and the first rib and the second rib are used to improve the connection strength to avoid deflection at the connection between the two, thereby improving the overall stability of the horizontal frame 5, enhancing the support strength of the horizontal channel 1, and ensuring construction safety.

[0051] Specifically, the support member 6 is a square tube.

[0052] In this embodiment, the lifting lugs 11 are provided to facilitate the lifting and installation of the horizontal frame 5 .

[0053] The installation principle of the high-altitude cantilever support frame provided in this embodiment is as follows: when it is necessary to support the horizontal channel 1, the number of horizontal frames 5 can be determined according to the length of the horizontal channel 1. First, before hoisting the horizontal frame 5, one end of the support member 6 is connected to the first connecting plate 8 by bolts, and the support member 6 and the first connecting plate 8 can rotate relative to each other. At the same time, a tether is tied to the other end of the support member 6. Then, the horizontal frame 5 is hoisted to the I-beam 4 through the lifting ear 11 on the horizontal frame 5, and the horizontal frame 5 is clamped to the periphery of the first flange plate through the clamping groove, wherein the support member 6 and the clamping plate 7 are connected. They are respectively located on both sides of the web to ensure the stability of the connection. Then, a clamping portion 91 is set on the side of the second flange plate close to the suspended end of the horizontal frame 5 at the position corresponding to the support member 6. The clamping portion 91 is clamped on the periphery of the second flange plate through the clamping groove 94 and fixed to the second flange plate through the fixing bolts 93 on the clamping portion 91. Then, the other end of the support member 6 is pulled close to the second connecting member through the tether and connected by bolts to complete the installation of the horizontal frame 5. Then, the horizontal channel 1 can be placed between the two fixing plates 10 and fixed by bolts to complete the overall installation. The horizontal frame 5 of the high-altitude cantilever support frame provided in this embodiment is connected to the first flange plate on the I-beam 4 in the form of a clip, which is convenient for disassembly. At the same time, a support member 6 is provided at the bottom of the horizontal frame 5. The horizontal frame 5, the support member 6 and the I-beam 4 are arranged in a triangular structure, which improves the supporting strength of the horizontal frame 5. At the same time, the two ends of the support member 6 are detachably connected to the I-beam 4 and the horizontal frame 5, which is convenient for installation and disassembly, can be circulated and used, and reduces construction costs. The support member 6 of the corresponding length can be replaced according to the I-beam 4 of different heights, thereby improving the scope of application. The workload of high-speed work is reduced, and the horizontal frame 5 and the support member 6 are in a split structure, which is convenient for installation and connection, easy to hoist, and reduces the installation risk. It can reduce the on-site installation time and the use time of the hoisting equipment, and improve the installation efficiency. Specifically, multiple horizontal frames 5 can be arranged at intervals along the length of the I-beam 4 according to the length of the horizontal channel 1 to support the horizontal channel 1. It has high flexibility and solves the technical problems that the support platform 2 of the existing support frame is long as a whole, which is not convenient for hoisting, has installation risks, and is difficult to disassemble by welding.

[0054] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
