Combined bridge deck structure of large-span bridge and construction method thereof
The invention relates to a combined bridge deck structure of a large-span bridge and a construction method of the combined bridge deck structure, and relates to the technical field of bridge construction. The structure comprises an ultra-high performance concrete layer laid on an orthotropic plate; a connecting assembly buried in the ultra-high performance concrete layer,which comprises a plurality of steel plate sets distributed at intervals in the transverse bridge direction, each steel plate set comprises a plurality of steel plates distributed at intervals in the bridge direction, the bottoms of the steel plates are fixedly connected to the orthotropic plates, and a plurality of open grooves distributed at intervals in the bridge direction are formed in the tops of the steel plates; aplurality of shear nails vertically arranged on the orthotropic plate; a single-layer reinforcing mesh, which comprises a plurality of first transverse reinforcing steel bars and a plurality of longitudinal reinforcing steel bars, the first transverse reinforcing steel bars and the longitudinal reinforcing steel bars are arranged in a criss-cross mode, and the first transverse reinforcing steel bars are placed in the open grooves. The local mechanical property and the overall mechanical property of the orthotropic plate can be improved, the weight of the combined bridge deck structure is not obviously increased, and the spanning capacity of the combined bridge deck structure is improved.
本申请涉及一种大跨径桥梁的组合桥面结构及其施工方法，涉及桥梁施工技术领域，包括：正交异性板；铺设在正交异性板上的超高性能混凝土层；埋设于超高性能混凝土层中的连接组件，其包括：多个沿横桥向间隔分布的钢板组，每个钢板组包括多个沿顺桥向间隔分布的钢板，钢板的底部固连于正交异性板上，顶部开设有多个沿顺桥向间隔分布的开口槽；若干个剪力钉，剪力钉竖直设置在正交异性板上；单层的钢筋网，包括多个第一横向钢筋和多个纵向钢筋，第一横向钢筋与纵向钢筋纵横交错布置，且第一横向钢筋搁置在开口槽中。本申请既能改善正交异性板的局部力学性能和整体力学性能，且不明显增加组合桥面结构重量，还提高组合桥面结构的跨越能力。
