DETAILED DESCRIPTION

[0019] ​​The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] As Figures 1-4 shown in the figure, the multi-limb multi-layer steel structure support column assembling device comprises two assembling units arranged side by side, each assembling unit comprises a roadbed box 10, a support column 11, multi-layer support beams, a construction platform, a first adjusting steel beam 40 and a second adjusting steel beam 41.

[0021] The roadbed box 10 is used for bearing the assembled multi-limb multi-layer steel structure support column. The roadbed box 10 is arranged at the bottom of the assembling device and is composed of a plurality of roadbed box units. The roadbed box 10 is used for stabilizing the assembling device and distributing the load downward.

[0022] The support column 11 is vertically fixed at the four corners of the roadbed box 10. The multi-layer support beams are installed on the support column 11 in the height direction. In this embodiment, the multi-layer support beams comprise a first layer of support beams 20, a second layer of support beams 21 and a third layer of support beams 22 arranged in sequence from low to high. The support beams are all frame beam structures and are provided with through holes. The horizontal section of the through hole is rectangular, and the size of the through hole is greater than the cross-sectional size of the assembled multi-limb multi-layer steel structure support column. The through holes of the multi-layer support beams vertically penetrate to form an assembling channel of the steel structure support column. The outer side of each layer of the support beams is provided with the construction platform, and the inner side of each layer of the support beams is provided with a plurality of first adjusting steel beams 40 extending into the through hole. The first adjusting steel beams 40 are used for positioning and supporting the side wall of the steel structure support column. Four sides of the through hole are respectively provided with one first adjusting steel beam 40. The first adjusting steel beam 40 is at least installed on the inner side of the first layer of support beams 20. According to the need, the first adjusting steel beam 40 can also be installed on the inner side of the second layer of support beams 21 or the third layer of support beams 22. The second adjusting steel beam 41 is arranged above the uppermost layer of the support beams, i.e. the third layer of support beams 22, and is used for positioning and connecting the top of the steel structure support column.

[0023] As Figure 4 shown, the construction platform comprises overhanging steel beams 31, scaffolding boards 30 and protective devices installed on the edges of the scaffolding boards 30. A plurality of overhanging steel beams 31 are connected in sequence to the outer side of each layer of the support beams. The scaffolding boards 30 are paved on the overhanging steel beams 31. The protective devices comprise safety vertical rods 32 and steel wire ropes 33. The safety vertical rods 32 are installed at intervals on the edges of the scaffolding boards 30, and the steel wire ropes 33 connect a plurality of safety vertical rods 32.

[0024] It should be noted that all support force transmission positions of the assembling device are provided with stiffening plates.

[0025] The positions and shapes of the first adjusting steel beam 40 and the second adjusting steel beam 41 can be finely adjusted according to the shape of the assembled structure. As Figure 3As shown, the first adjusting steel beam 40 is a U-shaped steel beam structure formed by welding three horizontal steel beams in sequence, which includes a positioning beam and two connecting beams connected at both ends of the positioning beam, and the two connecting beams are connected with the support beams of the layer where the first adjusting steel beam 40 is located, and the positioning beam is parallel to the support beams. According to the size of the multi-limb multi-layer steel structure support column, the length of the connecting beam is determined to determine the position of the positioning beam, so that when the multi-limb multi-layer steel structure support column is assembled, the side surface thereof can abut against or be connected with the positioning beam of the first adjusting steel beam 40, thereby ensuring the assembly accuracy of the multi-limb multi-layer steel structure support column. Of course, in some embodiments, the positioning beam of the first adjusting steel beam 40 and the connecting beams at both ends thereof can be connected in a movable manner, for example, a plurality of bolt holes are arranged on the connecting beams at intervals along the length direction of the connecting beams, and the positioning beam is connected with the bolt holes at different positions of the connecting beams by bolts to adjust the position of the positioning beam, which is suitable for the positioning and support of multi-limb multi-layer steel structure support columns of different sizes.

[0026] The second adjusting steel beam 41 is vertically arranged and is used for temporary connection with the top of the multi-limb multi-layer steel structure support column and can be used for height positioning of the multi-limb multi-layer steel structure support column. The second adjusting steel beam 41 can also have a telescopic structure for controlling the elevation.

[0027] When the multi-limb multi-layer steel structure support column needs to be assembled, the assembly device of the embodiment is first assembled on the ground. During the assembly process, the roadbed box 10 is first paved, and then the support columns 11 and the support beams are installed layer by layer, and the construction platforms, the first adjusting steel beam 40 and the second adjusting steel beam 41 of the corresponding layers are installed. After the assembly device is assembled, the multi-limb multi-layer steel structure support column can be assembled, the roadbed box 10 is used as the assembly base, and the multi-limb multi-layer steel structure support column is assembled layer by layer thereon, and it is ensured that the side surface of the steel structure support column is fixed with the first adjusting steel beam 40 and the top of the steel structure support column is fixed with the second adjusting steel beam 41, the welding of each layer of the support column of the steel structure support column and the installation of the connecting rods are performed, after the installation of the connecting rods of the steel structure support column is completed, the fixing measures of the connection between the roadbed box 10, the first adjusting steel beam 40, the second adjusting steel beam 41 and the steel structure support column are removed, and the completed steel structure support column is hoisted into place by using a crane.
