Steel-UHPC arch rib arch bridge and construction method thereof
The invention discloses a steel-UHPC arch rib arch bridge, and relates to the technical field of suspender cable arch bridges, the steel-UHPC combined arch rib comprises a bridge deck structural body, a steel-UHPC combined arch rib and tie bar assemblies, the steel-UHPC combined arch rib comprises arc-shaped arch ribs located on the two sides of the bridge deck structural body, the two longitudinal ends of each arc-shaped arch rib are arranged on the bridge deck structural body respectively, and the tie bar assemblies are arranged on the bridge deck structural body. A wind brace is arranged between every two arc-shaped arch ribs, each arc-shaped arch rib comprises a plurality of prefabricated mixed segment ribs, each prefabricated mixed segment rib comprises a built-in hollow thin-wall steel box body and a UHPC outer box body wrapping the periphery of the hollow thin-wall steel box body, and shear nails used for being embedded in the UHPC outer box bodies are arranged on the hollow thin-wall steel box bodies. The multiple prefabricated mixed segment ribs are spliced in the circumferential direction and connected through UHPC wet joints to form the arc-shaped arch rib. According to the arch bridge with the steel-UHPC arch rib, the steel-UHPC combined arch rib is light in self weight and suitable for larger arch bridge span, the hollow thin-wall steel box body can be used as a formwork for pouring outer wrapped concrete, an inner formwork is not needed, and construction is convenient.
本发明公开了一种钢‑UHPC拱肋的拱桥，涉及吊杆索拱桥技术领域，包括桥面结构体、钢‑UHPC组合式拱肋以及系杆组件，钢‑UHPC组合式拱肋包括位于桥面结构体两侧的弧形拱肋，弧形拱肋的纵向两端分别设于桥面结构体上，两个弧形拱肋之间设有风撑，弧形拱肋包括多个预制混合节段肋，预制混合节段肋包括内置的空心薄壁钢箱体和外包在空心薄壁钢箱体外周的UHPC外箱体，空心薄壁钢箱体上设有用于埋设在UHPC外箱体内的剪力钉，多个预制混合节段肋沿环向拼接并通过UHPC湿接缝连接形成弧形拱肋。本发明的钢‑UHPC拱肋的拱桥，钢‑UHPC组合式拱肋自重要轻，适用的拱桥跨径更大，且空心薄壁钢箱体可作为外包混凝土浇筑的模板，无需内模，施工方便。
