[0002] Y-shaped column structures are often constructed in construction projects. The Y-shaped column includes a Y-shaped steel bar frame. In the process of tying the Y-shaped steel bar frame, the two opposite diagonal supports at the top of the Y-shaped steel bar frame tend to tilt outward as the height increases, which can easily cause the Y-shaped steel bar frame to deform, and then cause the formwork surrounding the Y-shaped steel bar frame to be unable to be closed, resulting in quality problems such as insufficient thickness of the protective layer. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a positioning device for a Y-shaped steel bar skeleton and a construction method thereof, so as to solve the problem in the prior art that the two relatively inclined supports at the top of the Y-shaped steel bar skeleton are prone to tilt outward and deform as the height increases.
