Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a steel column butt correction tool. Background Art

[0002] During steel structure construction, steel columns are often welded to form longitudinal pillars. When steel columns are butt-jointed, there are clear specifications for the installation accuracy of the steel columns, such as the coaxiality between the steel columns and the elevation accuracy of the upper steel column.

[0003] During the construction of steel column docking, the upper steel column and the lower steel column are manually guided to dock. During the hoisting process, a plumb line is used to measure and align, and then the upper and lower steel columns are fixed with plywood and bolts. However, in order to meet the precise specifications, manual secondary correction is often required. In the prior art, the coaxiality and elevation of the steel column docking position are often achieved by welding top blocks at the docking positions of the upper and lower steel columns, and then setting a jack between the top blocks at the docking positions of the two steel columns. The angle and elevation of the steel column are adjusted through the cooperation of the jack and the top block. However, this not only complicates the process, but also causes damage to the parent material, and the top block can only be left or cut off after use, and cannot be reused, resulting in material waste.

[0004] Therefore, in order to overcome the shortcomings of the prior art, a steel column docking correction tool is proposed, which can effectively correct the elevation and coaxiality of the steel column, effectively improve the installation accuracy, and can be repeatedly used to avoid material waste.
