梁。 Stud bolts are installed on the upper and lower flange surfaces of the precast concrete girder main body, which has main reinforcement at the lower end of the girder and studs placed along the entire length of the girder, at approximately 1/4 of the length of the girder from both ends. In addition to burying I-type steel members, the ends of each I-type steel member are made to protrude from the end face of the main beam body, and tension steel members for introducing prestress are arranged over the entire length of the main beam body. Introducing prestressing into precast steel reinforced concrete girders.
