Combined box girder structure and construction method
The invention relates to the technical field of bridge engineering, in particular to a combined box girder structure and a construction method.The combined box girder structure comprises a bottom plate, prefabricated webs are arranged on the two sides of the bottom plate, a top plate is arranged above the two prefabricated webs, and steel ribs are arranged in the prefabricated webs; the upper ends and the lower ends of the steel ribs penetrate out of the prefabricated webs to be connected with the bottom plate and the top plate respectively, a plurality of cast-in-place transverse partition plates are arranged between the two prefabricated webs at intervals in the length direction of the combined box girder, and prefabricated transverse partition plates are arranged at supporting points of the two ends of the combined box girder. The combined box girder is light in hoisting weight, convenient to construct, high in web crack resistance and low in maintenance cost; and the construction method is simple.
本发明涉及桥梁工程技术领域，具体涉及一种组合箱梁结构及施工方法，包括底板，所述底板的两侧均设置有预制腹板，位于两预制腹板的上方设置有顶板，所述预制腹板内设置有钢骨，所述钢骨的上、下端分别穿出预制腹板与底板、顶板相连接，位于两预制腹板之间沿组合箱梁的长度方向间隔设置有多个现浇横隔板，且位于组合箱梁的两端支点处设置有预制横隔板。该组合箱梁吊装重量轻、施工方便、腹板抗裂能力强、养护费用低；同时施工方法简便。
