Description

Technical Field

[0001] The invention belongs to the technical field of steel structure building construction, and relates to a device for adjusting the verticality of steel columns of a building structure during the steel structure installation and construction process. Background Art

[0002] Modern industrial plants and workshops often use steel structures. The steel columns in the steel structures mostly use cup-shaped foundations, which have the advantages of fast construction speed, controllable quality, and structural safety. At present, during the installation of steel columns, cranes are usually used to control the verticality of the steel columns with cable wind ropes. When there are many steel columns, not only does it take a long time to occupy large equipment such as cranes, resulting in increased construction costs, but it is also subject to greater site restrictions, cumbersome operating procedures, and low construction efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a special steel column verticality adjustment device to solve the above problems, so as to save construction costs and improve construction efficiency.

[0004] The technical solution of the present invention is as follows:

[0005] The top end face of the lifting block is connected with the support frame, and the bottom end face of the lifting block is connected with the support frame, and the support frame is connected with the support frame at the bottom end.

[0006] The invention has the advantages of simple structure, convenient use and small size. After the lower end of the steel column is installed in the cup-mouth foundation, the verticality of the steel column can be fine-tuned with the help of a jack to ensure that the verticality of the steel column meets the design requirements. The invention has high construction efficiency and simple procedures, is not restricted by the construction site, can reduce the time occupied by the crane, and has good practicality.

[0018] like Figure 1 , Figure 2 As shown, the present invention comprises a support and a sliding bracket, and the sliding bracket can slide up and down on the support.

[0019] Structural diagram of the support Figure 3 , Figure 4 As shown, it includes two vertical plates 1 with plate surfaces facing each other, a load-bearing plate 2 is welded between the two vertical plates, two ends of the load-bearing plate 2 are respectively welded to the two vertical plates 1, and the plate surface of the load-bearing plate 2 is perpendicular to the plate surface of the vertical plates 1, and a lower supporting plate 3 is welded to the top edge of the load-bearing plate 2, the plate surface of the lower supporting plate 3 is perpendicular to the plate surfaces of the vertical plates and the load-bearing plates, and there is a certain gap between the two ends of the lower supporting plate 3 and the two vertical plates 1.

[0020] The structure of the sliding bracket is as follows Figure 5 , Figure 6 As shown, it includes two side panels 4 arranged opposite to each other, each side panel is provided with a slide groove 5 along the longitudinal direction of the side panel, a connecting plate 6 is welded between the two side panels, an upper support plate 7 is welded between the upper ends of the two side panels, and the lower ends of the two side panels are provided with through holes 8.

[0021] like Figure 1 , Figure 2As shown, the two vertical plates 1 of the support are respectively located on the outer sides of the two side plates 4 of the sliding bracket, the load-bearing plate 2 is inserted into the slide groove 5 on the two side plates, the lower support 3 is located between the two side plates 4 and below the upper support plate 7, and the through holes 8 are set at the lower ends of the two side plates and are partially located below the two vertical plates 1.

[0022] During the specific implementation of the present invention, in order to enhance the force bearing capacity of the load-bearing plate, two stiffening plates 9 may be welded between the two sides of the load-bearing plate 2 and the bottom surface of the lower support plate 3 .

[0023] In order to enhance the force bearing capacity of the upper support plate, two ribs 10 may be welded to the top surface of the upper support plate 7 , and both ends of each rib 10 are welded to the two side plates 4 respectively.

[0024] When the present invention is implemented, the surface of the connecting plate can be set to be perpendicular to the surface of the two side plates, and an upwardly recessed groove 11 is set in the middle of the bottom edge of the load-bearing plate and the connecting plate to avoid affecting the installation of the adjustment plate on the steel column during use.

[0025] When the present invention is manufactured, a sliding bracket is firstly processed with a steel plate, and then the load-bearing plate of the support is inserted into the slide grooves on the two side plates of the sliding bracket to ensure that the load-bearing plate can slide back and forth along the slide grooves, and then the two vertical plates are welded to the two ends of the lower support plate on the outer sides of the two side plates, and finally the lower support plate is welded on the load-bearing plate.

[0026] The use of the present invention is as follows:

[0027] like Figure 7 , Figure 8 As shown, after the steel column 12 is hoisted into the cup mouth 13, the verticality of the steel column is measured by a theodolite to determine the tilt direction and angle of the steel column. An adjustment plate 14 is welded to one side of the tilt direction of the steel column, one end of the adjustment plate 14 is welded to the steel column 12, and the other end extends to a certain length outside the cup mouth 13.

[0028] like Fig. 9 As shown, the lower ends of the two upright plates 1 of the support of the present invention are supported on the concrete surface outside the cup mouth 13, the part where the through holes are arranged at the lower ends of the two side plates 4 of the sliding bracket is located inside the cup mouth, and a pull rod 15 is passed through the through holes at the lower ends of the two side plates, and the pull rod 15 is located below the adjustment plate 14; a jack 16 is arranged on the lower support plate 3, and the upper end of the jack cylinder is supported on the bottom surface of the upper support plate 7.

[0029] like Fig.10As shown, the jack 16 is started to push the upper support plate 7 upward, so that the sliding bracket slides upward along the slide slot, driving the pull rod 15 to move upward, and the pull rod 15 applies an upward force to the adjustment plate 14 to correct the inclination angle of the steel column 12; after measuring the verticality of the steel column to meet the design requirements, a wedge block 17 is inserted at the bottom of the adjustment plate 14 to maintain the adjusted state of the steel column. Then the jack is retracted, the pull rod is removed, and the adjustment device is removed to complete the verticality adjustment of the steel column, as shown in FIG. Fig.11 shown.
