Steel structure positioning tool

The utility model belongs to the technical field of steel structure positioning tools, particularly relates to a steel structure positioning tool, and provides the following scheme aiming at the positioning problem: the steel structure positioning tool comprises a supporting column; the upper surface of the supporting column is fixedly connected with a mounting plate; a first sliding groove is formed in the upper surface of the mounting plate. The lower surface of the mounting plate is fixedly connected with an adjusting mechanism; a positioning mechanism is slidably mounted on the outer surface of the first sliding groove. By arranging the adjusting mechanism, rapid adjustment of the positioning mechanism is achieved, and the working efficiency is improved; and through the arrangement of the positioning mechanism, adjustment can be conducted according to the included angle generated when the steel structures are spliced and welded, splicing positioning of the steel structures with different splicing and weld
