[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Before the installation of this device is completed, use a crane to hang the upper H-shaped steel column 1. After the installation and fixation of this device is completed, the hook can be removed.

[0024] The first positioning assembly 2 also includes two sliding blocks 22 and a first sliding rod 23. The two sliding blocks 22 are respectively located in the upper and lower directions of the welding port 12. A cavity is provided inside the sliding block 22. The length of the cavity is half of the length of the sliding block 22. The cavity is connected to the end of the sliding block 22. A slideway is provided on the side wall of the sliding block 22, and the slideway is connected to the cavity.

[0025] The two ends of the first sliding rod 23 are slidably connected to the two cavities. The two side walls of the first sliding rod 23 are provided with limit rods 231. The limit rods 231 penetrate the slideway. The end of the sliding block 22 is provided with a threaded hole. The No. 1 bolt 21 penetrates the threaded hole and the H-shaped steel 1. When installing the sliding block 22, the threaded hole is aligned with the rib hole 11. The two sliding blocks 22 are connected through the first sliding rod 23. By sliding the sliding block 22, the bolt hole can select the corresponding rib hole 11. After the bolt hole is aligned with the rib hole 11, the No. 1 bolt 21 is screwed in, and the tail of the No. 1 bolt 21 is connected to the second positioning component 3.

[0026] The sliding block 22 and the second positioning assembly 3 are respectively arranged on both sides of the web of the H-shaped steel 1. There are two groups of second positioning assemblies 3, which are respectively located on the upper and lower H-shaped steels 1. Each group of second positioning assemblies 3 also includes three first positioning pieces 32 and two second sliding rods 33.

[0027] The second sliding rod 33 passes through both sides of the first positioning piece 32. The three first positioning pieces 32 slide vertically on the second sliding rod 33. The second sliding rod 33 connects the three first positioning pieces 32 into a whole. A threaded hole is also provided in the middle of the first positioning piece 32. The threaded hole can be aligned with the rib hole 11 by sliding the first positioning piece 32.

[0028] A No. 1 bolt 21 is screwed onto the first positioning piece 32 close to the welding port 12. After the No. 1 bolt 21 passes through the sliding block 22, the H-beam 1 and the first positioning piece 32, it is screwed into the nut to make the sliding block 22 and the first positioning piece 32 close to the H-beam 1, thereby completing the preliminary fixation of the H-beam 1; No. 2 bolts 31 are screwed onto the two first positioning pieces 32 away from the welding port 12, and the No. 2 bolts 31 connect the first positioning piece 32 and the third positioning assembly 4.

[0029] The third positioning assembly 4 and the sliding block 22 are located on the same side of the H-beam 1. The third positioning assembly 4 includes two second positioning pieces 41 and two third sliding rods 42. The second positioning piece 41 is slidably connected to the third sliding rod 42. A threaded hole is also provided in the middle of the second positioning piece 41, and the threaded hole is also aligned with the rib hole 11 by sliding. The second positioning piece 41 is connected to the two first positioning pieces 32 away from the welding port 12 by a No. 2 bolt 31. The No. 2 bolt 31 passes through the second positioning piece 41, the H-beam 1 and the first positioning piece 32 and is screwed into a nut, so that the first positioning piece 32 and the second positioning piece 41 clamp the H-beam 1.

[0030] The sliding block 22 and the second positioning piece 41 are located on one side of the H-shaped steel 1, and the first positioning piece 32 is located on the other side of the H-shaped steel 1. At this time, the two sides of the two H-shaped steels 1 have been fixed, and the upper H-shaped steel 1 cannot shake, so the hook can be withdrawn. The welding port 12 on one side of the first positioning piece 32 is exposed. If the welding conditions are met, the welding port 12 on one side of the first positioning piece 32 can be welded at this time. If welding is not performed immediately, the auxiliary plate 5 can be installed first to further enhance the stability of the structure. When welding is required, the auxiliary plate 5 can be removed for welding. If one side of the sliding block 22 has not been welded after welding one side of the auxiliary plate 5, the auxiliary plate 5 needs to be installed again to ensure the stability of the steel structure support.

[0031] The auxiliary plate 5 is located on the side of the first positioning plate 32. The auxiliary plate 5 is installed after the first positioning plate 32 is fixed. The auxiliary plate 5 includes an upper plate 51 and a lower plate 52. The upper plate 51 is slidably connected to the lower plate 52. By sliding the upper plate 51 and the lower plate 52, the overall length of the auxiliary plate 5 can be changed so that the auxiliary plate 5 connects the H-shaped steels 1 on the upper and lower sides. The upper plate 51 is close to the first positioning plate 32 in the middle of the upper layer, and the upper plate 51 is connected to the No. 2 bolt 31 that penetrates the upper H-shaped steel 1. The lower plate 52 is close to the first positioning plate 32 in the middle of the lower layer, and the lower plate 52 is connected to the No. 2 bolt 31 that penetrates the lower H-shaped steel 1. After the No. 2 bolt 31 passes through the upper plate 51 or the lower plate 52, it is screwed into the nut for fixing.

[0032] There is a gap between the upper plate 51 and the lower plate 52, and the No. 1 bolt 21 passes through the gap. When the welding port 12 on one side of the sliding block 22 needs to be welded, the sliding block 22 needs to be removed to expose the welding port 12. At this time, the nut is screwed off through the gap to further remove the sliding block 22. After removing the sliding block 22, the two H-shaped steels 1 are continued to be supported and fixed by the auxiliary plate 5, the second positioning assembly 3 and the third positioning assembly 4 to ensure that the upper H-shaped steel 1 is not deviated during welding.

[0033] All components of this structure can be disassembled and recycled. Positioning connection can be achieved through expansion and contraction according to different rib hole spacings. After welding, the components can be transferred to other steel structures for continued use, eliminating the steps of cutting ear plates and connecting plates, thus avoiding consumption and waste of materials.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
