Reinforced concrete combined bridge deck reinforced by steel bar-steel plate combined truss
The invention relates to the technical field of bridge engineering, in particular to a reinforced concrete composite bridge deck reinforced by a steel bar-steel plate composite truss. Comprising a steel bottom plate, upper chord steel bars, web member inclined bars, transverse steel bars, transverse fulcrum inclined bars, fulcrum circumferential steel bars, shear nails and a concrete plate. The steel bottom plate is welded on a grid beam consisting of a cross beam and a longitudinal beam, and a fold line haunch is arranged at a position close to the grid beam; the upper chord steel bars and the web member diagonal bars are arranged in the span direction of the bridge deck slab and welded to the steel bottom plate to form the steel bar-steel plate combined truss. Standardized, modularized and industrialized reinforcing steel bar products are utilized, the construction process is simplified, the construction difficulty is reduced, and the respective advantages of steel and concrete materials are fully exerted. Due to the stiffening effect of the steel bar-steel plate combined truss, the bearing capacity of the bridge deck is effectively improved, the thickness of the bridge deck is reduced, the structural weight of the bridge deck is close to that of an orthotropic steel bridge deck, and the bridge deck is suitable for large-span bridges.
本发明涉及桥梁工程技术领域，具体涉及一种钢筋‑钢板组合桁架加劲的钢砼组合桥面板。包括钢底板、上弦钢筋、腹杆斜筋、横向钢筋、横向支点斜筋、支点环向钢筋、剪力钉及混凝土板；钢底板焊接于由横梁、纵梁组成的格子梁上，并在近格子梁处设置折线加腋；上弦钢筋、腹杆斜筋沿着桥面板跨径方向布置，并与钢底板相互焊接形成钢筋‑钢板组合桁架。本发明利用标准化、模块化、工业化的钢筋产品，简化施工流程，降低施工难度，充分发挥了钢与混凝土材料各自的优势。由于钢筋‑钢板组合桁架的加劲作用，有效地提高了桥面板的承载能力，减小了桥面板厚度，结构重量与正交异性钢桥面板较为接近，适合用于大跨桥梁的桥面板。
