[0003] In the prior art, the upper steel column is hoisted vertically. When the upper steel column has a certain height, the upper steel column needs to be hoisted to a sufficient height before it can be docked with the lower steel column. The equipment cannot meet the lifting work. At the same time, the vertical upper steel column has a large hanging space, which is easily affected by the steel components erected around it. Moreover, the vertical upper steel column has poor stability during lifting. Under the action of gravity, The upper steel column is easy to break away from the clamping device, which affects the safety of the construction site

Embodiment Construction
[0056] like Figure 1 to Figure 16 As shown, it is a construction method for high-altitude butt joint of a round pipe column of the present invention, comprising the following steps:
[0057] a. Making an operating table 1, the center of the operating table 1 is provided with a through hole 4 for the operator to walk.
[0058] The console 1 includes an enclosure structure 2 and a bottom frame 3, and the enclosure structure 2 is an upper and lower hollow structure. The bottom frame 3 includes a base 5, a support 6, a skeleton 46 and a square support frame 7, and four support members 6 are uniformly welded to the base 5 in the circumferential direction. The frame 46 is welded between the two adjacent supports 6, and then the square support frame 7 is welded to the outer end of the frame 46. At this time, an embedded groove is formed between the support 6 and the frame 46, and then the steel plate 8 is inserted into the embedded groove. , for the operator to walk. The steel pl...

The invention discloses a tubular column high-altitude butt joint construction method. The method comprises the following steps that a, an operation table is manufactured; b, manufacturing a positioning assembly; c, fixing the positioning assembly; d, fixing an operation table; e, mounting a crawling ladder; g, adjusting the angle of the positioning plate; h, a limiting assembly is installed; i, manufacturing a tubular column clamping device; j, horizontally hoisting the upper circular pipe column; k, enabling the upper circular pipe column and the lower circular pipe column to correspond up and down; l, welding the upper circular tubular column and the lower circular tubular column; m, disassembling the tubular column clamping device; n, the limiting assembly is disassembled; o, the crawling ladder is disassembled; and p, the operation table is lifted out. According to the hoisting equipment, the upper circular pipe column can be horizontally hoisted, so that the hoisting height of the upper circular pipe column is obviously reduced, the hoisting equipment meets the horizontal hoisting work, meanwhile, the hoisting equipment is slightly influenced by steel members erected around, the stability of the upper circular pipe column in the horizontal state is good, the circular pipe column clamping device always clamps the upper circular pipe column, and the hoisting efficiency is improved. And the safety of a construction site is improved.
Description
technical field [0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a construction method for high-altitude butt joint of circular tubular columns. Background technique [0002] At present, in space steel structure engineering, large-diameter circular steel columns are very popular among architects and are often selected as vertical support members of steel structure roofs. The section size is large, and the steel column is usually installed on-site at both ends. Usually, the lower steel column is fixed first, and then the upper steel column is placed in place by a crane, and then the welding is corrected. For example, the prior art discloses a utility model patent named as an installation adjustment structure for steel column docking (application number: 202121748334.9), which can effectively ensure the accuracy of the installation elevation of the upper steel column and effectively control the upper steel column...
