Corrugated steel web combined box girder and construction method thereof
The invention discloses a corrugated steel web combined box girder and a construction method thereof.The combined box girder comprises a top plate, a bottom plate and at least two corrugated steel webs, the corrugated steel webs are arranged between the top plate and the bottom plate, and each corrugated steel web comprises a first web section and a second web section; the first web section comprises two first steel webs, the first ends of the two first steel webs are bent inwards and connected with each other, the second web section comprises a second steel web, and the second steel web is connected with the first ends of the first steel webs. By the adoption of the mode that the double-layer steel webs and the single-layer steel webs are combined, the shear rigidity and the bending rigidity of the steel webs at the bridge piers are improved, the weight of the suspended part is reduced, and the overall stability of the combined box girder is improved. The invention relates to the field of civil engineering bridges.
本发明公开了一种波形钢腹板组合箱梁及其施工方法，组合箱梁包括顶板、底板和波形钢腹板，波形钢腹板的数量为至少两个，波形钢腹板均设置在顶板和底板之间，波形钢腹板包括第一腹板段和第二腹板段，第一腹板段包括两个第一钢腹板，两个第一钢腹板的第一端向内弯折并相互连接，第二腹板段包括第二钢腹板，第二钢腹板与第一钢腹板的第一端连接。本发明通过采用双层钢腹板与单层钢腹板结合的形式，既提升了桥墩处钢腹板的抗剪刚度和抗弯刚度，又减轻了悬空部分的重量，提升组合箱梁的整体稳定性。本发明涉及土木工程桥梁领域。
