Steel bar positioning structure

The utility model relates to the technical field of building construction, and discloses a steel bar positioning structure which structurally comprises a base, stand columns are welded to the two sides of the upper end of the base, a sliding groove is formed in the upper end of the base, a limiting rod is installed at the upper end of the base in a sliding mode, and hinge seats are fixedly installed at the lower ends of the outer sides of the stand columns. By means of the base, the limiting rings, the limiting rods, the rubber blocks and the two-way lead screws, when steel bars are positioned, the steel bars can be pressed and limited through the two limiting rings, so that the steel bars are pressed and positioned in batches, subsequent tightening operation on a steel reinforcement cage is further facilitated, and the working efficiency is improved. And in the rotating process of the two-way lead screw, the two-way lead screw can wind the pull rope, the pull rope drives the limiting plate to rotate downward
