Combined bridge deck structure and construction method thereof
The invention relates to a combined bridge deck structure and a construction method thereof. The multiple stiffening ribs are arranged at intervals in the transverse bridge direction and fixed to the bottom of the bridge deck in the longitudinal bridge direction; the at least one transverse partition plate is vertically fixed at the bottom of the bridge deck slab; the ultra-high performance concrete layer is arranged at the top of the bridge deck slab, a plurality of cavities are formed between the ultra-high performance concrete layer and the bridge deck slab, all the cavities extend in the longitudinal bridge direction and are disconnected at intervals at the positions of the transverse partition plates, and the cross section of each cavity is in an arch shape. The cavities formed between the ultra-high performance concrete layer and the bridge deck slab transmit the upper wheel load to the stiffening ribs below the bridge deck slab to be dispersed based on the arch effect, the stress of the bridge deck slab is reduced, and the stress distribution of the bridge deck slab is improved. Furthermore, the connecting assemblies are adopted to replace shear nails, and the finished reinforcing mesh is laid on the connecting assemblies, so that the on-site construction process is simplified.
本发明涉及一种组合桥面结构及其施工方法，其包括：桥面板；多个加劲肋，多个所述加劲肋沿横桥向间隔设置，并均沿纵桥向固定在所述桥面板的底部；至少一个横隔板，所述横隔板竖向固定在所述桥面板的底部；超高性能混凝土层，所述超高性能混凝土层设置于所述桥面板的顶部，并与所述桥面板之间形成多个空腔，每个所述空腔均沿纵桥向延伸，并在所述横隔板处间隔断开，且每个所述空腔的横截面均为拱形。本发明通过超高性能混凝土层与桥面板之间形成的空腔基于拱效应将上部轮载传递至桥面板下方的加劲肋分散，减少桥面板的受力，改善桥面板的应力分布。进一步的，本发明采用连接组件代替剪力钉，并在连接组件上铺设成品钢筋网，简化现场施工流程。
