Bridge deck slab capable of being used for steel-UHPC composite beam bridge, steel channel beam, beam bridge and construction method thereof
The invention provides a bridge deck capable of being used for a steel-UHPC (Ultra High Performance Concrete) composite beam bridge, a steel channel beam, a beam bridge and a construction method thereof the bridge deck, and aims to solve technical problems that the steel-UHPC composite beam bridge is overweight in bridge structure, not high in span, poor in crack resistance of a concrete bridge deck and the like. The bridge deck is a one-way rib UHPC bridge deck and comprises a thin bridge deck body and a plurality of UHPC transverse ribs integrally formed at the bottom of the bridge deck body, and the one-way rib UHPC bridge deck is not provided with longitudinal ribs; the steel channel beam is a U-shaped channel beam and comprises a bottom plate, webs connected to the two sides of the bottom plate and flange plates connected to the top faces of the webs, and longitudinal bridge direction stiffening ribs are arranged on the bottom plate and the webs; the beam bridge comprises a plurality of full-hole simply-supported beams which are mutually connected in the longitudinal direction of a bridge, and each full-hole simply-supported beam comprises a one-way rib UHPC bridge deck slab, a steel tank beam and a shear key. The beam bridge adopts a mode that in-plant construction is firstly performed to form a full-hole simply supported beam, and then on-site hoisting is performed. The bridge deck is advantaged in that the self weight of the bridge structure is reduced, stress is reasonable, pier top crack resistance is high, joints are few, construction is easy and convenient, and durability is excellent.
本发明提供一种可用于钢‑UHPC组合梁桥的桥面板、钢槽梁、梁桥及其施工方法，用以解决钢‑UHPC组合梁桥存在的桥梁结构偏重、跨径不高以及混凝土桥面板抗裂性差等技术问题。桥面板为单向肋UHPC桥面板，包括薄型的桥面板本体和一体成型于桥面板本体底部的多个UHPC横肋，单向肋UHPC桥面板不设置纵肋。钢槽梁为U型槽梁，包括底板、连接于底板两侧的腹板以及连接于腹板顶面的翼缘板，底板和腹板上均设有纵桥向加劲肋。梁桥包括沿桥梁纵向相互连接的多个整孔简支梁，整孔简支梁包括单向肋UHPC桥面板以及钢槽梁和剪力键。梁桥采用先厂内施工形成整孔简支梁而后现场吊装的模式。本发明减轻了桥梁结构自重，受力合理、墩顶抗裂性强，且接缝少、施工简便、耐久性优。
