Description

Technical Field

[0001] The utility model relates to the field of equipment for steel column installation, and more specifically, to an auxiliary device for connecting steel columns of steel structures. Background Art

[0002] Steel columns are longitudinal load-bearing members in steel structure buildings, and their installation accuracy directly affects the stability and safety of steel structure buildings. When installing steel columns, due to factory length limitations, it is often necessary to butt the steel columns to make them reach the required length. In the process of butt-jointing steel structures, in order to improve the butt-jointing verticality of the upper and lower steel columns, multiple auxiliary plates are usually welded at circumferential intervals between the upper and lower steel columns, and a first through hole is provided on the lower auxiliary plate (the auxiliary plate on the lower steel column), and a second through hole corresponding to the first through hole is provided on the upper auxiliary plate (the auxiliary plate on the upper steel column). When in use, an adjusting screw is used to pass through the through hole on the auxiliary plate on the lower steel column, and the adjusting screw is fixed to the lower auxiliary plate through a nut, and then the adjusting nut is screwed on the upper part of the adjusting screw to adjust the position of the multiple adjusting nuts to Located on the same horizontal plane, then the upper section of the steel column is hoisted above the lower section of the steel column, and the upper section of the steel column is lowered to the second through hole on the upper auxiliary plate on which the adjusting screw passes. At this time, the upper section of the steel column is similarly placed on multiple adjusting nuts. When the upper section of the steel column and the lower section of the steel column have vertical deviations, the upper section of the steel column and the lower section of the steel column can be vertically aligned by adjusting multiple adjusting nuts, and the gap between the upper section of the steel column and the lower section of the steel column can be adjusted to the required welding (see the patent with application number 201821397905.7 for details). However, in the above structure, each time it is used, it is necessary to pre-adjust multiple adjusting nuts to the same horizontal plane. Since whether multiple adjusting nuts are located on the same horizontal plane depends on the naked eye judgment of the construction personnel, it is not only time-consuming to adjust, but also the naked eye judgment is likely to cause a large deviation in the height between the multiple adjusting nuts, which increases the workload for the subsequent adjustment of the verticality of the upper section of the steel column.
