Steel reinforced concrete combined box girder bridge and joint treatment method
The invention discloses a steel reinforced concrete combined box girder bridge and a joint treatment method, and belongs to the technical field of civil engineering. Transverse partition plates are welded to the interior of a U-shaped steel web at equal intervals in the longitudinal direction, and a flange plate is welded to the top of the U-shaped steel web; the flange plate is a cuboid steel plate, fixing pins are welded to the top of the flange plate at equal intervals, epoxy cement mortar is arranged on the outer side of the top of the flange plate, and rubber strips are arranged on the inner side of the flange plate; a first prefabricated plate and a second prefabricated plate are arranged at the top of the epoxy cement mortar, and high-strength cement mortar is arranged at the tops of the two ends of each of the first prefabricated plate and the second prefabricated plate. The joint formed by connecting the middle of the first prefabricated plate and the middle of the second prefabricated plate is fixed through the micro-expansion cement mortar, the joint generated at the two ends is paved through the high-strength cement mortar, the prefabricated plate and the cast-in-placestructure can form a whole, and the panel is jointly stressed.
本发明公开了一种型钢混凝土组合箱梁桥及缝处理方法，土木工程技术领域，所述U形钢腹板的内部沿纵向等间距焊接有横隔板，顶部焊接有翼缘板；所述翼缘板为长方体钢板，翼缘板的顶部等间距焊接有固定销钉，翼缘板的顶部外侧布置环氧水泥砂浆，内侧布置橡胶条；所述环氧水泥砂浆顶部设置有第一预制板和第二预制板，所述第一预制板和第二预制板两端顶部均设有高强水泥砂浆。本发明通过使用微膨胀水泥砂浆固定第一预制板和第二预制板中间连接形成的接缝，使用高强水泥砂浆铺筑两端部产生的接缝，能够使预制板块与现浇结构组成整体，形成面板共同受力。
