[0002] In the construction process of the pier, the reinforcing bar needs to be pre-buried on the pier body of the pier and then poured, that is, the pier body reinforcing bar should be pre-buried in the pile cap. Because the pier body is high and the pre-buried reinforcing bar is long, temporary consolidation is needed, which requires the use of a pier body pre-buried reinforcing bar positioning structure.

[0003] After searching, the patent with the patent publication number CN212834961U provides a pier body pre-buried reinforcing bar positioning device, which includes a first elastic section, a first adjusting section and a second adjusting section respectively arranged at both ends of the first elastic section, a second elastic section detachably connected to the first adjusting section and the second adjusting section at both ends, a positioning plate arranged on the first adjusting section and the second adjusting section, and a clamping groove arranged on the positioning plate. The first elastic section, the first adjusting section, the second adjusting section and the second elastic section can be attached to the pier body reinforcing bar, and the positioning plate can be clamped in the clamping groove on the pier body reinforcing bar, temporarily fixing the first elastic section, the first adjusting section, the second adjusting section and the second elastic section on the pier body reinforcing bar. During installation, scaffolding is not needed, especially during pouring, deformation does not occur, and the fixing effect of temporary consolidation can be effectively improved.

[0004] Based on the above search, combined with the prior art, it is found that the pier body pre-buried reinforcing bar positioning device similar to the above-mentioned prior art can only limit the reinforcing bar on the outside, and cannot prevent the reinforcing bar from shifting inward.
