[0011] A rotating assembly, which is used to drive the top support assembly to rotate to directly below the mounting block.

[0012] By adopting the above technical solution, installation blocks are added on both sides of the precast unit, so that a force application point can be provided for the top support assembly from the outside of the precast unit, which is beneficial to the lifting and positioning of the precast unit, and facilitates the installation in the early stage and the disassembly in the later stage; the installation blocks are arranged in a vertical offset manner, and the displacement of the top support assembly is realized through the rotation assembly, so as to avoid the top support assembly blocking the normal positioning of the precast unit to be spliced, which is beneficial to improving the installation fluency, achieving the purpose of vertical assembly, reducing the influence of the small construction site on the steel column assembly construction, and improving the installation efficiency of the steel column.

[0013] Preferably, the rotation assembly includes a gear ring, a gear meshing and driving with the gear ring, and a motor for driving the gear to rotate; the gear ring and the gear are rotatably connected to the upper end surface of the base, and the rotation axes of the gear ring and the gear are both perpendicular to the base.

[0014] By adopting the above technical solution, under the drive of the motor and the meshing drive of the gear and the gear ring, it is beneficial to realize the function of accurately and stably rotating the top support assembly.

[0015] Preferably, the top support assembly is a vertical hydraulic cylinder, and the vertical hydraulic cylinder is arranged on the upper surface of the gear ring.

[0035] 1. By adding installation blocks on both sides of the precast unit and staggering the installation blocks of the upper and lower precast units, not only can a force application point be provided for the top support assembly from the outside of the precast unit, but also the top support assembly can be prevented from blocking the normal positioning of the precast unit to be spliced, so as to facilitate lifting and lowering of the precast unit, and at the same time facilitate the preliminary installation and later disassembly; the displacement of the top support assembly is realized through the rotation assembly, thereby, it is beneficial to improve the installation fluency, achieve the purpose of vertical assembly, reduce the influence of the small construction site on the steel column assembly construction, and improve the installation efficiency of the steel column;

[0036] 2. After the precast units are assembled, the steel structure assembly mechanism is removed, but the base is retained as the steel column foundation, which improves the overall stability of the steel column, and since the steel structure assembly mechanisms are all installed on the outside of the steel column, it is convenient to disassemble the steel structure assembly mechanism from the steel column, thereby realizing the purpose of reusing the steel structure assembly mechanism, which is beneficial to reducing the manufacturing cost.

In this embodiment, the prefabricated unit 5 is a columnar steel frame. One end of the prefabricated unit 5 is fixed with an insertion block 52, and the other end of the prefabricated unit 5 is recessed with an insertion hole for the insertion block 52 to be inserted. The adjacent upper and lower prefabricated units 5 are positioned and spliced by the insertion of the insertion block and the insertion hole. And connection blocks 53 are fixed on the inner sides of both ends of the prefabricated unit 5. Bolts are used to lock the connection blocks 53 of the adjacent upper and lower prefabricated units 5 to realize the splicing and fixing of the prefabricated unit 5 to form a stable steel column. In addition, a plurality of positioning holes are opened on the upper end surface of the base 1, and the positioning holes are for the steel pipes at the lower end of the prefabricated unit 5 to be inserted, so as to ensure the stability of the prefabricated unit 5 during the installation process and ensure the accuracy of the position of the installation block 51.

[0046] Installation blocks 51. Each prefabricated unit 5 is equipped with two installation blocks 51, and the two installation blocks 51 are respectively arranged on the two outer sides of each prefabricated unit 5. Among the two adjacent prefabricated units 5 after assembly, the installation blocks 51 of the two prefabricated units 5 are arranged offset up and down. In this embodiment, taking the height direction of the steel column as the axis, the offset angle of the installation blocks 51 of the adjacent upper and lower prefabricated units 5 is 60°.

[0047] Top support assemblies. There are two top support assemblies in total. In this embodiment, the top support assembly is a vertical hydraulic cylinder 6.

[0048] Rotation assembly. The rotation assembly includes a gear ring 4, a gear 3 meshing and driving with the gear ring 4, and a motor 2 for driving the gear 3 to rotate. Among them, an installation seat 11 is fixed on the upper end surface of the base 1, the motor 2 is installed at the installation seat 11, the gear ring 4 and the gear 3 are rotatably connected to the upper end surface of the base 1, and the rotation axes of the gear ring 4 and the gear 3 are both perpendicular to the base 1. The range enclosed by the inner side of the gear ring 4 serves as the assembly area of the steel column. The positioning holes are located within the area enclosed by the gear ring 4.
