Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a steel column positioning construction device for a steel structure building. Background Art

[0002] Steel structure building is a new type of building system, which breaks through the industry boundaries between real estate, construction and metallurgy, and integrates them into a new industrial system. This is the steel structure building system that is generally favored by industry insiders. In the positioning construction of steel columns in steel structure buildings, some construction sites use manual hand-held steel columns. When the installation holes on the steel columns cannot be aligned with the reserved bolts on the ground, workers need to manually rotate the steel columns to align them. However, this operation method cannot ensure the accurate positioning of the steel columns, and it is laborious to manually rotate the steel columns directly.

[0003] Therefore, in view of this situation, it is urgent to design and produce a steel column positioning construction device for steel structure buildings to meet the needs of actual use. Utility Model Content

[0004] In order to overcome the problem that in the existing technology of steel column positioning construction of steel structure buildings, some construction sites use manual hand-held steel columns. When the installation holes on the steel columns cannot be aligned with the reserved bolts on the ground, workers need to manually rotate the steel columns for alignment. However, this operation method is difficult to ensure the accurate positioning of the steel columns, and it is laborious to directly rotate the steel columns manually, the embodiment of the utility model provides a steel column positioning construction device for steel structure buildings. The technical solution is as follows:

[0005] A steel column positioning construction device for a steel structure building comprises a base and a fixed cylinder rotatably arranged on the base, a through hole being provided at the center of the base, a plurality of insertion holes being provided circumferentially on the base and being fixed to the ground by anchor bolts; a circular ring slide groove being provided on the base, and the fixed cylinder being rotatably arranged in the slide groove by bearings; an annular chamber being provided inside the cylinder wall of the fixed cylinder, four hydraulic cylinders being equidistantly fixed circumferentially on the inner wall of the annular chamber, one end of the movable shaft of the hydraulic cylinder being oriented toward the center of the fixed cylinder and being fixed with a clamping plate, and a side of the clamping plate away from the hydraulic cylinder being able to abut against the outer wall of the steel column.

[0006] Furthermore, two limit rods are slidably provided on the inner wall of the fixed cylinder, and the two limit rods are symmetrically arranged at the upper and lower positions of the hydraulic cylinder. One end of the limit rod is fixedly connected to the clamping plate, and the other end of the limit rod passes through the inner wall of the fixed cylinder and is located inside the annular chamber and fixes the limit plate. The limit rod can ensure that the clamping plate will not rotate when it moves horizontally.

[0007] Furthermore, a rubber pad is detachably connected to one side of the clamping plate that contacts the steel column. The rubber pad can make it easier for the clamping plate to fit the surface of the steel column and can increase friction to avoid sliding.

[0008] Furthermore, reinforcing plates are symmetrically fixed on both sides of the outer wall of the hydraulic cylinder, and both ends of the reinforcing plates are fixedly connected to the two inner walls of the annular chamber respectively.

[0009] Furthermore, a plurality of handles are fixed circumferentially on the outer wall of the fixing tube, so that the fixing tube can be rotated by operating the handles, so that the mounting holes on the steel column are aligned with the bolts reserved on the ground.

[0010] Furthermore, two fixing blocks are symmetrically fixed on the base, and through holes are provided on the sides of the fixing blocks. After the steel column is installed, the device can be lifted up by a crane through the through holes to remove the device.

[0011] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the device has a simple and practical structure, and the steel column can be moved and positioned by arranging hydraulic cylinders in multiple directions, and the rotation adjustment of the steel column can be achieved by rotating the fixing tube arranged on the base, so that the mounting hole of the steel column is aligned with the reserved bolt on the bottom surface for easy fixation.
