文章介绍了一种预应力混凝土简支箱梁,在其端头预留纵向钢筋,在预制安装到位后,绑扎、焊接普通钢筋,立模浇注钢筋混凝土纵向湿接头,体系转换为预应力混凝土和普通钢筋混凝土组合而成的结构连续梁桥的一种做法,并介绍了该方法在实际工作中的应用。 In this paper, a kind of prestressed concrete simply supported box girder is introduced. Longitudinal reinforcement is reserved at the tip of the box girder. After prefabrication is completed, the normal steel bars are bound and welded, and the longitudinal wet joint of reinforced concrete is poured into the vertical mold. The system is converted into prestressed concrete and Ordinary reinforced concrete combination of a continuous beam structure of a practice, and describes the method in practical application.
