Prefabricated small box girder hidden cover beam connected by prestressed steel beams
The invention relates to the technical field of building construction engineering, and discloses a prefabricated small box girder hidden cover beam connected by prestressed steel beams. Comprising a plurality of hidden cover beams arranged in the transverse bridge direction, a plurality of prefabricated small box beams arranged on the two sides of each hidden cover beam and arranged in the longitudinal bridge direction and a prestress system arranged in the web direction of the prefabricated small box beams, and splicing seam areas with female and male teeth meshed are formed between the prefabricated small box beams and the hidden cover beams. The hidden cover beam is formed by splicing a plurality of hidden cover beam prefabricated sections arranged in the transverse bridge direction, an embedded shear-resistant stirrup system is formed between each hidden cover beam prefabricated section and the small box beam end solid sections on the two sides, and prestressed steel beams for coupling connection between the sections are tensioned and anchored. The prestressed steel beams for coupling connection between the segments are distributed in the hollow projection range of the small prefabricated box girder and staggered with the embedded shear-resistant stirrup system, and the shear-resistant bearing capacity of the splicing interface of the small prefabricated box girder and the cast-in-place hidden cover beam can be improved.
本发明涉及建筑施工工程技术领域，且公开了一种预应力钢束连接的预制小箱梁隐盖梁，包括沿着横桥向布置的若干隐盖梁、分设在每一根隐盖梁两侧并沿着顺桥向布置的若干预制小箱梁以及沿着预制小箱梁腹板方向配置的预应力体系，预制小箱梁与隐盖梁之间形成呈阴阳齿啮合的拼缝区，所述隐盖梁通过若干沿着横桥向布置的隐盖梁预制节段拼接而成，每一隐盖梁预制节段，均与两侧的小箱梁端部实心段之间形成嵌合抗剪箍筋体系，并张拉锚固有节段间耦合连接用预应力钢束，节段间耦合连接用预应力钢束分布在预制小箱梁空心投影范围内，并与嵌合抗剪箍筋体系相错设置，能够提高预制小箱梁与现浇隐式盖梁拼接界面处的抗剪承载力。
