The manufacturing process of the flange steel frame is as follows: first, multiple single-piece separate stirrups are bent into a specific shape, and multiple single-piece separate stirrups are connected by longitudinal force-bearing steel bars to form a flange steel frame. Similarly, the beam rib steel frame is also made by tying multiple single-piece separate stirrups with longitudinal force-bearing steel bars. During construction, first tie the beam rib steel frame on the tire frame, hoist the flange steel frame into the mold, and insert the connecting bars at the connection between the flange steel frame and the beam rib steel frame. After installing the side mold, concrete can be poured. However, this traditional prefabricated T-beam will have the following problems:

[0003] First, the steel bars need to be cut into single-piece separate stirrups of corresponding lengths. Each single-piece separate stirrup can be bent before it can be tied with the longitudinal force-bearing steel bars. The number of bending times is large and the workload is large. Multiple separate single-piece separate stirrups are only tied with the longitudinal force-bearing steel bars, the integrity of the steel bar skeleton is poor, and the constraint force on the core area concrete of the wing plate steel bar skeleton and the beam rib steel bar skeleton is low.
