[0002] During the construction process, compared with reinforced concrete, steel structures have higher strength and better earthquake resistance, and the required steel structures can be manufactured in advance, greatly reducing the construction period.

[0003] When installing steel columns, after hoisting them into place, the lower fixing plate is temporarily bolted to the concrete base. Once the verticality is corrected, welding is performed. Currently, verticality correction is often performed by lifting the lower fixing plate using tools such as steel pipes. Due to the heavy weight of steel columns, this method is time-consuming and labor-intensive, and accuracy is difficult to control, requiring further improvement. Summary of the Invention

[0004] The object of the present invention is to provide a steel truss factory building column installation structure, which is convenient for correcting the verticality of the steel structure columns to solve the defects mentioned in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A steel bar truss factory building column mounting structure, comprising a fixing frame sleeved on a steel structure column, the fixing frame being provided with a square hole vertically penetrating therethrough, the steel structure column passing through the square hole, the fixing frame being provided with a fastener for tightening the steel structure column; the fixing frames being provided with two fixing frames opposite to each other up and down, support columns being fixedly mounted between the two fixing frames located on the front, back, left and right sides of the steel structure column, and hydraulic cylinders being provided on the front, back, left and right sides of the steel structure column, one end of the piston rod of the hydraulic cylinder being hinged to the corresponding support column through a horizontally extending hinge shaft, a support base plate being movably mounted on one end of the cylinder body of the hydraulic cylinder, a universal ball head being fixedly mounted on one end of the cylinder body of the hydraulic cylinder, and a universal ball seat matching the universal ball head being fixedly mounted on the top of the support base plate.

[0006] As a further improvement, the fixing frame includes two right-angled plates arranged opposite to each other, the right-angled plates are provided with two side plates perpendicular to each other, the two right-angled plates enclose a square, and the square hole is located between the two right-angled plates.

[0007] As a further improvement, the two ends of the right-angle plate are respectively provided with a first connecting part and a second connecting part, the first connecting parts of the two right-angle plates are hinged to each other through a vertically extending rotating shaft, and the second connecting parts of the two right-angle plates are connected by a locking screw.

[0008] As a further improvement, the fastener includes a fastening screw screwed on each of the side plates, and the fastening screw is arranged perpendicular to the corresponding side plate.

[0009] As a further improvement, the right-angle plate is provided with an outwardly extending mounting portion, and the support column is fixedly installed between two of the mounting portions.

[0010] As a further improvement, a connecting column is hinged on the support column through the hinge shaft, a slot is provided at the end of the connecting column away from the support column, and an insert block matching the slot is provided at one end of the piston rod of the hydraulic cylinder; a mounting screw hole is provided on the insert block, and a positioning hole is provided on the outer wall of the connecting column corresponding to the position of the mounting screw hole, and a mounting bolt passes through the positioning hole and is screwed into the mounting screw hole.

A square hole 10 is provided vertically through the two right-angled plates 8, and the steel structure column 1 passes through the square hole 10. A first connecting portion 11 and a second connecting portion 12 are integrally formed at each end of the right-angled plates 8. The first connecting portions 11 of the two right-angled plates 8 interlock with each other. The first connecting portions 11 of the two right-angled plates 8 are hinged to each other via a vertically extending rotating shaft 13. The second connecting portions 12 of the two right-angled plates 8 are connected by a locking screw 14. The locking screw 14 passes through the two second connecting portions 12 and is screwed into a locking nut. After removing the locking screw 14, the two right-angled plates 8 can be separated from the ends corresponding to the second connecting portion 12, thereby opening one side of the square hole 10 so that the fixing frame 7 can be placed on the steel structure column 1.

[0020] The fixing frame 7 is provided with fasteners for tightening the steel structure column 1, and the fasteners include fastening screws 15 screwed on each side plate 9. The fastening screws 15 are arranged perpendicular to the corresponding side plate 9. After the fixing frame 7 is put on the steel structure column 1, the four fastening screws 15 are rotated to tighten the steel structure column 1, thereby preventing the fixing frame 7 from moving relative to the steel structure column 1.

[0021] Two fixing brackets 7 are provided above and below each other. A vertically extending support column 16 is fixedly installed between the two fixing brackets 7 located on the front, back, left, and right sides of the steel structure column 1. The lower end of the right-angle plate 8 located above and the upper end of the right-angle plate 8 located below are respectively integrally formed with an outwardly extending mounting portion 17. The two mounting portions 17 on the same fixing bracket 7 enclose a circle coaxially arranged with the square hole 10. The upper and lower ends of the support column 16 are respectively welded or fixedly installed on the corresponding mounting portion 17 by bolts. In this embodiment, each mounting portion 17 is respectively connected to the ends of two support columns 16. Figure 1 and Figure 3 As shown, hydraulic cylinders 18 are respectively provided on the front, back, left and right sides of the steel structure column 1. One end of the piston rod of the hydraulic cylinder 18 is hinged to the corresponding support column 16 through a horizontally extending hinge shaft 19. By rotating the hydraulic cylinder 18 around the hinge shaft 19, the inclination angle of the hydraulic cylinder 18 relative to the steel structure column 1 can be adjusted. One end of the cylinder body of the hydraulic cylinder 18 is tilted in the direction away from the steel structure column 1; a support base plate 20 is movably installed at one end of the cylinder body of the hydraulic cylinder 18, and the support base plate 20 is supported on the ground. A universal ball head 21 is fixedly installed at one end of the cylinder body of the hydraulic cylinder 18 by bolts, and a universal ball seat 22 matching the universal ball head 21 is fixedly installed on the top of the support base plate 20 by bolts, and the universal ball head 21 is rotatably installed in the universal ball seat 22.

[0022] When installing the steel structure column 1, first hoist the steel structure column 1 to the top of the concrete base 2, make the fixing studs 3 on the top of the concrete base 2 pass through the mounting holes on the fixing plate 4 at the lower end of the steel structure column 1, and install fixing nuts 6 on the fixing studs 3 on the upper and lower sides of the fixing plate 4 to pre-fix the fixing plate 4; respectively put the two fixing brackets 7 on the steel structure column 1, tighten the locking screws 14 to fix the two right-angle plates 8 of the fixing bracket 7, and tighten the four fastening screws 15 to fix the fixing bracket 7 on the steel structure column 1; construction workers can use Use tools such as a line caster to measure the verticality of the installation of the steel structure column 1. When the steel structure column 1 is installed tilted, loosen the fixing nuts 6 on the upper and lower sides of the fixing plate 4. The hydraulic cylinder 18 on the corresponding side will extend to drive the steel structure column 1 to tilt in the opposite direction at a certain angle until the steel structure column 1 is installed vertically. After the adjustment is completed, tighten all the fixing nuts 6 and weld the fixing plate 4, fixing studs 3 and fixing nuts 6. Finally, remove the locking screws 14 and remove the fixing frame 7 from the steel structure column 1.

[0023] A connecting post 23 is hingedly connected to the support post 16 via a hinge shaft 19. A square slot 24 is provided at the end of the connecting post 23 away from the support post 16. An insert 25 is welded to one end of the piston rod of the hydraulic cylinder 18, matching the slot 24. Insert 25 is provided with mounting screw holes 26 extending radially along the connecting post 23. Positioning holes 27 are provided on the outer wall of the connecting post 23, corresponding to the mounting screw holes 26.
