Abstract

This utility model discloses a positioning tool for precast hollow column embedded reinforcing bars, relating to the field of building construction technology. The positioning tool includes an angle steel track frame, reinforcing bar limiting clips, bolts, and nuts. There are four angle steel track frames, each with a perforated slot. The four angle steel track frames are connected and fixed together by bolts and nuts to form a rectangular frame. The reinforcing bar limiting clips are placed at intervals on each angle steel track frame, and bolts are passed through the perforated slots and the reinforcing bar limiting clips from bottom to top, and then locked in place with nuts. This utility model features simple structure, convenient operation, reliable construction quality, high tool turnover rate, and high cost-effectiveness.
