[0040] The scaffolding system 1 cooperates with the rigid skeleton 2 to gradually build the steel skeleton 100. First, a scaffolding segment 11 is built, and a rigid skeleton segment 21 is built in the accommodating cavity of the scaffolding segment 11. The longitudinal reinforcement 102 of the steel skeleton 100 is passed through the positioning plate 211 to facilitate the positioning of the longitudinal reinforcement 102, and then the main reinforcement 103 of the steel skeleton 100 is tied or welded in turn, so as to complete the construction of a steel skeleton segment 101, and then the next scaffolding segment 11, the next rigid skeleton segment 21 and the next steel skeleton segment 101 are built in turn until the steel skeleton 100 is built as a whole, and then the steel skeleton 100 is hoisted as a whole to the installation position, which has high safety, does not need to be directly constructed at the installation position, and reduces the amount of high-altitude operations; at the same time, the first plate 2111 and the second plate 2112 cooperate to make the shape of the positioning plate 211 adjustable to meet the construction requirements of variable-section cable towers, and has strong versatility.

[0041] It should be noted that both the scaffolding system 1 and the rigid frame 2 are made of steel bars or steel pipes and are constructed by welding, which will not be described in detail here.

[0042] Preferably, in this embodiment, the first plate 2111 is configured as a bamboo plywood, and the second plate 2112 is configured as a steel plate, which is convenient for disassembly and assembly, and has low production cost, high strength, and light weight.

[0044] In this embodiment, two second plates 2112 are spaced apart at both ends of the first plate 2111 along the first horizontal direction, so that when the steel skeleton 100 is constructed, the cross-section of the steel skeleton 100 is adjustable along the first horizontal direction.

[0045] In other embodiments, two second plates 2112 may be spaced apart at both ends of the first plate 2111 along the second horizontal direction, so that when the steel skeleton 100 is constructed, the cross-section of the steel skeleton 100 is adjustable along the second horizontal direction; or, second plates 2112 are arranged along the circumference of the first plate 2111, so that the cross-section of the steel skeleton 100 is adjustable along both the first horizontal direction and the second horizontal direction.

[0046] Specifically, the scaffolding system 1 includes an outer frame system 12 and an inner frame system 13. The outer frame system 12 is arranged in a ring shape outside the steel frame 100, and the steel frame 100 is in a ring shape on the horizontal plane; the inner frame system 13 is arranged inside the steel frame 100. With the above arrangement, the outer frame system 12 and the inner frame system 13 cooperate with each other, so that construction workers can work from both the inside and outside of the steel frame 100 at the same time, thereby improving work efficiency.

[0047] It can be understood that the external frame system 12 is composed of multiple external frame segments connected to each other in the vertical direction, and the internal frame system 13 is composed of multiple internal frame segments connected to each other in the vertical direction. An external frame segment, an internal frame segment, a rigid skeleton segment 21 and a steel skeleton segment 101 are located at the same height to form a working plane.

[0048] More specifically, the external frame system 12 includes a plurality of external frames 121, which are spliced ​​together in the horizontal direction, and at least one of the external frames 121 is horizontally positionable.

[0050] More specifically, the inner frame system 13 includes a plurality of inner frames 131, which are arranged at intervals in the horizontal direction, and at least one of the inner frames 131 is adjustable in the horizontal direction. The above arrangement facilitates the construction and disassembly of the inner frame system 13, and facilitates the transportation of materials during the construction process.

[0051] Preferably, in this embodiment, two inner frames 131 are arranged at intervals along the first horizontal direction, wherein one of the inner frames 131 is positionally adjustable via a self-locking pulley structure.

[0052] It should be noted that the above-mentioned pulley structure is a commonly used existing technology in this field, and its specific structure is not described here in detail.

[0053] More specifically, the inner frame system 13 further includes a lap plate 132, which is arranged between two adjacent inner frames 131. The arrangement of the lap plate 132 facilitates the transportation of materials and the collaborative work of the construction workers on the two inner frames 131.

When the folding plate 112 is parallel to and connected to the bearing plate 1111, the limit block 1121 abuts against the fixed frame 111. With the arrangement of the above-mentioned folding plate 112, when the folding plate 112 is unfolded, it can carry construction personnel and equipment, which is convenient for tying or welding the steel frame 100; when the folding plate 112 is turned up, it is convenient for the overall lifting of the steel frame 100 to prevent collision.

[0055] More specifically, the folding plate 112 is detachably connected to the fixing frame 111. With the above arrangement, a folding plate 112 of a suitable size can be selected according to actual construction requirements, and the folding plate 112 has strong versatility.

[0056] In this embodiment, the extension direction of the steel skeleton 100 is set at an angle to the second horizontal direction, and the corresponding folding plate 112 can be adaptively adjusted to adapt to the inclination angle of the steel skeleton 100 while facilitating the adjustment of the distance between the folding plate 112 and the steel skeleton 100, thereby ensuring the convenience of construction workers in tying steel bars.

[0057] Specifically, the rigid skeleton segment 21 is provided with a first positioning frame 212 extending along a first horizontal direction, and a second positioning frame 213 extending along a second horizontal direction, and the main reinforcement 103 of the steel skeleton 100 is detachably connected to the first positioning frame 212 and / or the second positioning frame 213, and the first horizontal direction is perpendicular to the second horizontal direction. With the above arrangement, both the first positioning frame 212 and the second positioning frame 213 can carry the main reinforcement 103 of the steel skeleton 100, which is convenient for workers to tie or weld.

[0058] More specifically, the first positioning frame 212 is provided with a first positioning slot, the second positioning frame 213 is provided with a second positioning slot, and the main rib 103 can abut against the inner wall of the first positioning slot and / or the inner wall of the second positioning slot.

[0059] It is understandable that the main reinforcement 103 is configured with a first main reinforcement 103 extending along the first direction and a second main reinforcement 103 extending along the second direction. When constructing the steel skeleton segment 101, the first main reinforcement 103 is placed in the first positioning groove, and the second main reinforcement 103 is placed in the second positioning groove, and then tied or welded, which reduces the workload of construction personnel, saves time and is efficient.

[0060] Preferably, in this embodiment, both the first positioning frame 212 and the second positioning frame 213 are channel steel structures or angle steel structures commonly used in the art, which will not be described in detail herein.
