[0026] An embodiment of the first aspect of the present application provides a three-dimensional space steel structure support and positioning steering device, as Figure 1 and Figure 2 shown, including a base 100, a standard bracket 200, a height adjustment bracket 300 and a universal shaft assembly 400. Among them, the base 100 is a structure for installing and supporting other components, the standard bracket 200 is a bracket with a certain standard height, the height adjustment bracket 300 can realize height adjustment, and the universal shaft assembly 400 realizes position adjustment.
[0027] As Figure 3 shown, the base 100 can be a welded structural member and can be stably placed on the ground.
[0028] As Figure 5 shown, the standard bracket 200 is detachably connected to the base 100, so as to have a certain height and can support components at a certain height. A guiding hole is provided at the upper end of the standard bracket 200, and the guiding hole can guide other components. In implementation, the height of the standard bracket 200 can be made into various types, such as height specifications of 0.5 m, 1 m, 1.5 m, 2 m, etc., and can be selected according to the actual height requirements when selecting.
[0029] As Figure 7 shown, the height adjustment bracket 300 includes a support plate 310, a screw 320 and an adjustment sleeve 330. The screw 320 is connected below the support plate 310. The adjustment sleeve 330 is provided with internal threads, and the adjustment sleeve 330 is screwed onto the screw 320. The screw 320 cooperates with the guiding hole, and the lower surface of the adjustment sleeve 330 abuts against the upper surface of the standard bracket 200. The entire height adjustment bracket 300 is placed on the standard bracket 200 through the adjustment sleeve 330. In this way, when the position of the adjustment sleeve 330 changes relative to the screw 320, the distance between the support plate 310 and the standard bracket 200 changes, so as to support components of different heights. A first rib plate 340 can be provided between the support plate 310 and the screw 320 to improve the connection firmness between the support plate 310 and the screw 320.
[0030] As Figure 9 shown, the universal shaft assembly 400 includes a mounting plate 410, a universal ball 420, and a connecting member 430. The mounting plate 410 is detachably connected to the support plate 310, so that the entire universal shaft assembly 400 is mounted on the height adjustment frame 300. The mounting plate 410 is provided with a receiving groove 411. The universal ball 420 is fitted in the receiving groove 411. The connecting member 430 is connected to the universal ball 420. The connecting member 430 is used to connect to the steel structure. The universal ball 420 can rotate in the receiving groove 411, thereby changing the position of the connecting member 430 to adapt to the position of the steel structure hub node.
[0031] As Figure 1 and Figure 2 shown, in use, each support and positioning steering device corresponds to a steel structure hub node. The connecting member 430 is connected to the steel structure hub node. By adjusting the relative position of the adjusting sleeve 330 and the screw 320, the length of the screw 320 inserted into the guiding hole can be changed, thereby changing the height of the entire height adjustment frame 300 to adapt to the position of the steel structure hub node. The universal shaft assembly 400 is connected to the height adjustment frame 300 to achieve the positioning and support of the steel structure hub node.
[0032] Compared with the prior art, the three-dimensional space steel structure support and positioning steering device can achieve height adjustment through the adjusting sleeve 330 of the height adjustment frame 300 to achieve Z-axis position adjustment. By rotating the universal ball 420 in the receiving groove 411, the position adjustment in the X-Y plane can be achieved, thereby achieving three-dimensional space position adjustment, meeting the adjustment requirements of the three-dimensional space steel structure, reducing construction errors, and ensuring construction quality.
[0033] In some embodiments, such as Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the mounting plate 410 includes a positioning plate 440 and two limiting plates 450. The upper surface of the positioning plate 440 is provided with a hemispherical groove 441, and mounting threaded holes 442 are provided around the hemispherical groove 441. The limiting plate 450 is provided with a special-shaped groove 451. The special-shaped groove 451 is a part of a hemisphere, and the size of the special-shaped groove 451 gradually decreases from bottom to top. It can be buckled on the universal ball 420 to realize the limitation of the universal ball 420. The special-shaped grooves 451 on the two limiting plates 450 and the hemispherical groove 441 form a receiving groove 411. The limiting plate 450 is provided with a mounting through hole 452, and the mounting through hole 452 and the mounting threaded hole 442 are connected by bolts. When installing the universal ball 420, first place the universal ball 420 into the hemispherical groove 441, then relatively buckle the two limiting plates 450 on the universal ball 420. The special-shaped groove 451 and the hemispherical groove 441 form a receiving groove 411, and the universal ball 420 can be restricted from slipping out of the receiving groove 411. Then, fix the limiting plate 450 to the positioning plate 440 with bolts to realize the installation of the universal ball 420.
[0034] In some embodiments, as Figure 12 shown, the mounting through hole 452 is a stepped through hole, and the bolt can fall into the stepped through hole to avoid the exposure of the bolt and not affect the rotation of the universal ball 420.

The positioning plate 440 is connected and fixed to the support plate 310 through bolt connection to realize the installation of the universal shaft assembly 400 and the height adjustment bracket 300.
[0036] In some embodiments, as Figure 9 、 Figure 14 and Figure 15 shown, a connecting sleeve 460 is provided at the upper end of the universal ball 420. An internal thread is provided inside the connecting sleeve 460. The connecting member 430 is provided with a threaded shaft 470. The threaded shaft 470 cooperates with the connecting sleeve 460 to realize the detachable connection between the connecting member 430 and the universal ball 420, which is convenient for subsequent disassembly.
[0037] In some embodiments, as Figure 7 shown, a flange 350 is provided at the lower end of the adjusting sleeve 330. The flange 350 is arranged around the adjusting sleeve 330 for one week, increasing the contact area between the adjusting sleeve 330 and the standard bracket 200, making the entire height adjustment bracket 300 placed on the standard bracket 200 more stable.
[0038] In some embodiments, such as Figure 3 and Figure 4 shown, the base 100 includes a first vertical pipe 110, a first horizontal plate 120 and four cross beams 130. The first horizontal plate 120 is disposed at the upper end of the first vertical pipe 110. The four cross beams 130 are evenly disposed at the lower end of the first vertical pipe 110. The four cross beams 130 form a cross-shaped structure, making the whole base 100 more stable when placed on the ground and not prone to tipping over. A first guide pipe 140 is provided in the first vertical pipe 110. The first conduit penetrates the first horizontal plate 120. The first guide pipe 140 is connected to the inside of the first vertical pipe 110 through a first connecting plate 150. The number of the first connecting plates 150 can be two groups, which are respectively connected and fixed from the upper end and the lower end of the first guide pipe 140, making the installation of the first guide pipe 140 more firm. To improve the firmness of the base 100, a second rib plate 160 can be welded between the first vertical pipe 110 and the cross beam 130, and a third rib plate 170 can be welded between the first vertical pipe 110 and the first horizontal plate 120.
[0039] In some embodiments, such as Figure 5 and Figure 6 shown, the standard bracket 200 includes a second vertical pipe 210, a second horizontal plate 220 and a third horizontal plate 230. The second horizontal plate 220 and the third horizontal plate 230 are respectively disposed at the lower end and the upper end of the second vertical pipe 210, forming a connection structure at both ends. A second guide pipe 240 is provided in the second vertical pipe 210. The second guide pipe 240 penetrates the second horizontal plate 220 and the third horizontal plate 230. The second guide pipe 240 is connected to the inside of the second vertical pipe 210 through a second connecting plate 250. The number of the second connecting plates 250 can be two groups, which are respectively connected and fixed from the upper end and the lower end of the second guide pipe 240, making the installation of the second guide pipe 240 more firm.

The screw 320 can extend into the first guide pipe 140. The second connection holes 221 and the first connection holes 121 are connected by bolts and nuts, realizing the detachable connection between the base 100 and the standard bracket 200.
[0041] An embodiment of the second aspect of this application provides a construction method for installing a steel structure by using the three-dimensional space steel structure support and positioning steering device of the first aspect, as follows Figure 16 shown, including the following steps: S1: Plan a grid on the ground assembly site. The spacing of the grid is determined according to the average spacing of the steel structure hub nodes. The grid can realize the positioning of the base 100.
[0042] S2: According to the X-axis and Y-axis coordinate data of the steel structure hub nodes, calculate the point positions of the base 100 in the grid, and install the base 100 at the point positions, so that the base 100 corresponds to the position of the steel structure hub node. That is to say, the base 100 is located below this steel structure hub node.
[0043] S3: According to the Z-axis coordinate data of the steel structure hub nodes, calculate the required height of the standard bracket 200, install the standard bracket 200 with the corresponding height, and insert the screw 320 of the height adjustment frame 300 into the connecting hole to realize the installation of the height adjustment frame 300 and the standard bracket 200. For example, if the Z-axis coordinate data of the steel structure hub node is 3.3m, then the heights of the base 100, the standard bracket 200, the height adjustment frame 300 and the universal shaft assembly 400 should be 3.3m. Among them, the height of the base 100 is known and fixed. Assuming the height of the base 100 is 1m, then a 2m standard bracket 200 can be selected, and the remaining 0.3m is realized by the adjustment of the height adjustment frame 300.
[0044] S4: Weld the connecting piece 430 of the universal shaft assembly 400 at the positioning position of the steel structure hub node to realize the connection between the connecting piece 430 and the steel structure hub node.
[0045] S5: Lift the steel structure hub node above the height adjustment frame 300, adjust the position of the adjustment sleeve 330, so as to change the height of the height adjustment frame 300, so that the mounting plate 410 can be installed on the support plate 310, so as to realize the installation of the universal shaft assembly 400 and the standard bracket 200.
[0046] S6: Repeat steps S2 to S5, so that each steel structure hub node is connected to the height adjustment frame 300 through the universal shaft assembly 400 to realize the positioning of the entire steel structure. Then weld the steel structure hub nodes and the space members to realize the positioning, support and welding of the entire steel structure on the ground.
[0047] S7: After all the space hub nodes and space members are welded and installed, remove all the mounting plates 410 and the support plates 310. When lifting the steel structure, the universal shaft assembly 400 is separated from the standard support 200, realizing the disassembly of the universal shaft assembly 400 and the standard support 200. Then hoist the welded steel structure to the installation position (such as the top of a building) for installation.
[0048] S8: After the steel structure is hoisted and installed, cut off the connecting piece 430 on the hub node of the steel structure, realizing the separation of the connecting piece 430 from the steel structure, that is, realizing the separation of the universal shaft assembly 400 from the steel structure. The universal shaft assembly 400 can be recycled for turnover use and can be used for the positioning and support of the next steel structure.
[0049] Compared with the prior art, when installing the steel structure, this construction method can realize height adjustment through the adjusting sleeve 330 of the height adjustment frame 300, realizing the Z-axis position adjustment. By rotating the universal ball 420 in the receiving groove 411, the X-Y plane position adjustment can be realized, so as to realize the three-dimensional space position adjustment, meet the adjustment requirements of the three-dimensional space steel structure, reduce the construction error, and ensure the construction quality.
