[0038] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0039] See Figures 1 to 8 The large-span scaffolding provided in this embodiment includes a main body 100 and a support frame 200.

[0040] The main body 100 includes a sub-frame 110, with connecting flanges 111 provided at both ends of the sub-frame 110. There are multiple sub-frames 110, which are connected end-to-end to form the main frame via the connecting flanges 111. A support frame 200 includes a support portion 210 for being set up on the bottom surface. There are multiple support frames 200, each of which is provided on both sides of the main body 100 and is detachably connected to the main body 100. There are multiple hanging portions 300, which are spaced apart on the main body 100 along the extension direction of the main body 100.

[0041] Specifically, in this embodiment, a plurality of sub-frames 110 are connected to form the main body 100 , and are connected to the support frame 200 to form a support structure.

[0042] When in use, multiple sub-frames 110 are directly connected and then connected to the support frame 200 for splicing. After use, they can be disassembled and transferred, and are easy to assemble and disassemble and can be used multiple times.

[0043] Furthermore, since the sunken floor indoors precludes the use of supporting structures, the scaffold can be directly lifted using lifting equipment or, for example, wire rope. When using a wire rope, one end is connected to the lifting unit, and the other end is connected to a high point such as a beam, thereby connecting the main body 100 to the building's load-bearing structure. This structure allows the pressure exerted on the main body 100 to be transmitted to the building's load-bearing structure via the wire rope, thereby increasing the support capacity of the scaffold's midsection and effectively improving the safety of long-span scaffolding.

[0044] like Figure 6 In this embodiment, the sub-frame 110 includes a support rod 112. Connecting flanges 111 are provided at both ends and both sides of the support rod 112.

[0045] The connecting flanges 111 at both ends and both sides of the support rod 112 can form a detachable connection structure. When multiple sub-frames 110 are connected end to end, they can be connected through the rear end connecting flange 111 of the front support rod 112 and the front end connecting flange 111 of the rear support rod 112.

[0046] Furthermore, when the width of the scaffolding needs to be increased, multiple sub-frames 110 can be arranged along the width direction, and the parallel sub-frames 110 can be detachably connected using bolts through the connecting flanges 111 on both sides of the support rods 112, thereby widening the large-span scaffolding.

[0047] Furthermore, when multiple sub-frames 110 are arranged in parallel and at intervals, a sub-frame 110 can be vertically arranged between two adjacent sub-frames 110, with the front and rear ends of the vertically arranged sub-frame 110 respectively connected to the connecting flanges 111 on both sides of the parallel sub-frames 110. In this structure, multiple sub-frames 110 arranged in parallel and at intervals are connected to form an integral structure, so that the forces acting on the multiple sub-frames 110 can be dispersed throughout the overall structure and borne by the multiple sub-frames 110, thereby improving the stability and load-bearing capacity of the overall structure.

[0048] In this embodiment, there are two support rods 112. Figure 5 The two support rods 112 are parallel and spaced apart, a connecting rod 113 is provided between the two support rods 112 , and the connecting rod 113 is inclined and has its two ends connected to the two support rods 112 respectively.

[0049] Specifically, each sub-frame 110 in this embodiment includes two parallel support rods 112. A connecting rod 113 is provided between the two support rods 112 to connect the two support rods 112 to fix the relative positions of the two support rods 112. Connecting flanges 111 are provided at both ends and sides of the two support rods 112 to facilitate connection and combination with other sub-frames 110.

[0050] Please refer again Figure 5 In this embodiment, there are multiple connecting rods 113. The multiple connecting rods 113 are arranged in a triangular structure between two parallel supporting rods 112.

[0051] The plurality of connecting rods 113 form a plurality of triangular structures between two parallel supporting rods 112. The triangular structures have excellent stability, so that the structure of the sub-frame 110 is very stable, and has good load-bearing capacity and pressure resistance.

[0052] like Figure 2 In this embodiment, multiple sub-racks 110 are connected end-to-end to form a long rack. There are multiple long racks, and the multiple long racks are arranged in parallel and at intervals. A sub-rack 110 is arranged between two adjacent long racks, and the ends of the sub-rack 110 are respectively connected to the two long racks via flanges.

[0053] Specifically, multiple sub-frames 110 in this embodiment are connected end-to-end to form a long frame. The main body 100 in this embodiment includes multiple long frames. After the multiple long frames are arranged in parallel and spaced apart, a sub-frame 110 is installed between two adjacent long frames, perpendicular to the extension direction of the long frames. The front and rear connection flanges 111 of the sub-frame 110 are respectively connected to the connection flanges 111 on both sides of the two long frames by bolts, thereby connecting the two long frames into an integral load-bearing structure.

[0054] After the multiple long frames are connected, a sub-frame 110 is connected between every two long frames, so that the multiple long frames are connected together to form an integral structure, further improving the force-bearing capacity of the main body 100.

[0055] Please refer again Figure 2 and Figure 4 In this embodiment, the long-span scaffold further includes a horizontal support frame 400. The length of the horizontal support frame 400 is the same as the length of the support rod 112. The horizontal support frame 400 is detachably disposed between two adjacent sub-frames 110.

[0056] After the main body 100 is connected, when personnel need to work on the main body 100, the horizontal support frame 400 can be installed at the position where the personnel need to stay, so that the personnel can have a place to stand or stay. Since the length of the horizontal support frame 400 is the same as the length of the support rod 112, the horizontal support frame 400 can be installed at any position between any two sub-frames 110 on the main body 100 as needed, and can be disassembled and assembled at any time, which is very convenient.

[0057] like Figure 8 In this embodiment, overlapping portions 410 are respectively provided at both ends of the horizontal support frame 400. The overlapping portions 410 are adapted to the support rods 112.

[0058] Specifically, the support rod 112 in this embodiment is a round rod, and the surface of the overlapping portion 410 that connects with the support rod 112 is an arc surface, which can fit with the outer surface of the support rod 112 so that the two ends of the horizontal support frame 400 can be overlapped between two spaced apart support rods 112 respectively.

[0059] In this embodiment, the support frame 200 includes a support rod and a connecting sleeve 220. The support rod is the support portion 210. The connecting sleeve 220 is disposed at the top of the support rod and is provided with a plurality of connecting portions 221 for connecting to the connecting flange 111. The plurality of connecting portions 221 are spaced and evenly arranged on the connecting sleeve 220 along the circumference of the support portion 210.

[0060] The support rod is erected on the ground to support the main body 100. The connecting sleeve 220 in this embodiment is a hollow structure, which is sleeved on the top of the support rod. The connecting flanges 111 at both ends of the main body 100 can be connected to the connecting part 221, and the support rod can be connected to the main body 100 to support the main body 100.

[0061] Among them, the connecting portion 221 in this embodiment is a flange of the same specification as the connecting flange 111. The flange on the support frame 200 and the connecting flange 111 on the main body 100 are detachably connected by bolts, which facilitates the disassembly and assembly of large-span scaffolding.

[0062] Furthermore, there are four support frames 200 in this embodiment, and the four support frames 200 are respectively disposed at the four corners of the main body 100 to achieve stable support for the main body 100 .

[0063] In addition, as an implementable method, when there is a structure capable of bearing force below the middle section of the long-span scaffold, a support frame 200 can be added between the two sub-frames 110 in the middle of the main body 100, such as Figure 3 The flanges on both sides of the support frame 200 can be connected to the connecting flanges 111 of the two sub-frames 110 on both sides, thereby increasing the support points of the long-span scaffolding and further improving the force-bearing capacity of the long-span scaffolding.

[0064] In this embodiment, the support frame 200 further includes a movable foot disposed at the bottom end of the support portion 210 .

[0065] When a large-span scaffold needs to be moved, the main body 100 or the support frame 200 can be directly pushed, and the large-span scaffold can be moved over a short distance by moving the supporting legs.

[0066] In this embodiment, the hanging portion 300 is a hanging ring that is detachably provided on the main body 100 .

[0067] Specifically, the lifting ring in this embodiment is detachably mounted on the support rod 112, and a groove is provided on the lifting ring for fixing a wire rope or a hook.

[0068] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the aforementioned embodiments, or that some or all of the technical features therein may be replaced with equivalents.
