Prefabricated corrugated steel web assembled bridge and construction method thereof
The invention discloses a prefabricated corrugated steel web spliced bridge which comprises a plurality of box girder units formed by splicing an upper left prefabricated beam, an upper right prefabricated beam, a lower left prefabricated beam and a lower right prefabricated beam. The upper left prefabricated beam and the upper right prefabricated beam are symmetrically arranged and each comprise an upper corrugated steel web arranged in the longitudinal direction, the tops of the upper corrugated steel webs are embedded in the concrete top plate, and an extension type upper L-shaped steel plate is arranged at the end of the inner side of the concrete top plate. The upper L-shaped steel plates are welded and connected and are connected with concrete top plates of the left upper precast beam and the right upper precast beam by pouring concrete; the left lower precast beam and the right lower precast beam are similar to the left upper precast beam and the right upper precast beam in structure; the upper corrugated steel web of the left upper precast beam is in threaded connection with the lower corrugated steel web of the left lower precast beam, and the upper corrugated steel web of the right upper precast beam is in threaded connection with the lower corrugated steel web of the right lower precast beam. The structure is stable, light in weight, high in strength, convenient to hoist, erect and assemble, small in field cast-in-place and construction surface and high in construction efficiency.
本发明公开了一种预制波形钢腹板拼装桥梁，包括多个箱梁单元，其均由左上预制梁、右上预制梁、左下预制梁和右下预制梁拼装而成；左上预制梁和右上预制梁对称设置，均包括沿纵向设置的上波形钢腹板，其顶部预埋设置在混凝土顶板内，混凝土顶板的内侧端部设置有外延型的上L型钢板，上L型钢板焊接相连并通过浇筑混凝土连接左上预制梁和右上预制梁的混凝土顶板；左下预制梁和右下预制梁与左上预制梁和右上预制梁的结构类似；左上预制梁的上波形钢腹板和左下预制梁的下波形钢腹板螺接相连，右上预制梁的上波形钢腹板和右下预制梁的下波形钢腹板螺接相连。本发明结构稳固、轻质高强，便于吊装架设和拼装，现场现浇及施工面较小，施工效率高。
