[0002] During the construction of steel-concrete continuous beams, the concrete beam sections are constructed using conventional methods and are located at both ends of the steel beam. After the concrete beam sections are completed, the steel beam is hoisted and spliced ​​and fixed with the concrete beam.

[0003] However, at present, the steel beam is in a suspended state during hoisting. When it is close to the concrete beam and connected with it, the steel beam is prone to shaking, which poses a great safety hazard in construction.

[0004] However, some existing pre-embedded positioning parts for bridge construction are all welded for structural splicing at the construction site, which is inefficient. In addition, the mechanical properties of the weld scars of the pre-embedded positioning parts for bridge construction that have just been welded are not stable, which will affect the progress of the project to a certain extent. Welding the pre-embedded positioning parts for bridge construction in a workshop and then rotating them will cause them to occupy a large space, and the protruding hook-shaped structure thereon is also easily deformed due to collision, which leads to a certain degree of use defects. For this reason, the present invention proposes a pre-embedded positioning part for bridge construction and a construction method thereof to solve the above problems. Summary of the invention
