Quickly-constructed steel-concrete combined bridge deck slab segment connecting structure
The invention relates to the technical field of bridge design and construction, in particular to a rapidly-constructed steel-concrete combined bridge deck slab segment connecting structure. Single-side fixing bolts and connecting plates are arranged on the upper surfaces of the tail ends of the steel bottom formwork sections with the transverse stiffening ribs to serve as bottom sealing plates at the splicing positions of the steel bottom formworks, annular steel bars are arranged above the tail ends of the steel bottom formwork sections, the annular steel bars of the two steel bottom formwork splicing sections are arranged at the splicing positions in a staggered mode to form buckles, and a plurality of transverse steel bars are arranged in the buckles. And finally, on-site concrete is poured on the spliced section steel bottom formworks to form an integral steel-concrete combined bridge deck slab. According to the structure, the connecting structure form between the steel-concrete combined bridge deck slab sections is optimized, butt welding of a large number of steel plates and high-precision bolt connection are not needed when the bridge deck slab steel formwork sections are connected in the construction process, the construction difficulty is greatly reduced, the construction efficiency is improved, and the construction cost is reduced.
本发明涉及桥梁设计施工技术领域，具体来说是一种快速化施工的钢混凝土组合桥面板节段连接构造。在带横向加劲肋的钢底模板节段末端上表面设置单侧固定螺栓及连接板作为钢底模板拼接处的底封板，钢底模板节段末端上方设置环形钢筋，两钢底模板拼接节段的环形钢筋在拼接处交错布置形成环扣，环扣内部布置若干横向钢筋，最后于拼接节段钢底模板上浇筑现场混凝土形成整体的钢混组合桥面板；本构造优化了钢混组合桥面板节段间的连接结构形式，施工过程中桥面板钢模板节段连接时无需大量钢板对接焊接、高精度的螺栓连接，大幅降低了施工难度，提高施工效率，降低施工成本。
