Fabricated steel-concrete combined pier and bent cap connecting system and construction method thereof
The invention provides a fabricated steel-concrete combined pier and bent cap connecting system and a construction method thereof, and belongs to the technical field of building parts of roads, railways or bridges. The fabricated steel-concrete combined pier and bent cap connecting system comprises a steel-concrete combined pier, a bent cap, steel members and fasteners, the steel-concrete combinedpier, the steel members and the bent cap are sequentially installed, the steel-concrete combined pier comprises a steel shell, stiffening ribs and shear keys, the steel shell is a core mold, a spaceconstructed by the steel shell is filled with the reinforced concrete, the stiffening ribs are arranged on the periphery of the steel shell, and the shear keys are arranged at the junction of the steel shell and the reinforced concrete. The steel members are fixed to the steel shell, and the fasteners penetrate through the steel members to realize the connection of the bent cap and the steel-concrete combined pier. The system is simple in structure, high in strength, light in dead weight, high in bearing capacity, firm in connection, high in construction speed and convenient to use, fabricatedconstruction can be adopted, and the defects that in existing sleeve connection, the grouting compactness is difficult to control, detection is difficult, and the self-weight of the prefabricated part is large can be overcome.
本申请提供一种装配式钢混组合桥墩与盖梁连接系统及其施工方法，属于道路、铁路或桥梁的建筑零件技术领域。包括钢混组合桥墩、盖梁、钢构件、紧固件，钢混组合桥墩、钢构件、盖梁顺次安装，所述钢混组合桥墩包括钢壳、加劲肋、剪力键构成，钢壳为芯模，钢壳构建的空间内填充钢筋混凝土，钢壳的周边设置有加劲肋，钢壳与钢筋混凝土的交界处设置剪力键，钢构件与钢壳固定，所述紧固件贯穿钢构件，实现盖梁与钢混组合桥墩的连接。本申请结构简单、强度大、自重轻，承载能力高，连接牢固，施工速度快且方便，并可采用装配式施工，可以克服目前采用套筒连接存在浆料质量难以控制灌浆密实度和难以检测以及预制构件自重大等弊病。
