Double-deck steel truss PC composite structure bridge and construction method thereof
The invention discloses a double-deck steel truss PC composite structure bridge and a construction method thereof.The bridge comprises an upper deck slab, a lower deck slab, truss web members, an upper joint and a lower joint, the top ends of the truss web members are fixedly connected with the upper deck slab through the upper joint, and the bottom ends of the truss web members are fixedly connected with the lower deck slab through the lower joint to form a double-deck; wherein through supporting holes are formed in the two longitudinal edges of the upper-layer bridge deck slab, lap joint reinforcing steel bars are reserved at the supporting holes, supporting grooves are formed in the tops of the two longitudinal edges of the lower-layer bridge deck slab, lap joint reinforcing steel barsare reserved at the supporting grooves, reinforcing ribs of the upper joint and the lower joint are provided with reinforcing steel bar holes in a penetrating mode, and the lap joint reinforcing steelbars are in lap joint through the reinforcing steel bar holes. Concrete is cast in place in the supporting holes and the supporting grooves, so that the upper joint and the lower joint are solidified, the double-layer bridge deck with high wind resistance, low dead weight and low manufacturing cost is achieved, the space and resource utilization rate of the bridge is increased, and the bridge issimple in structure, low in manufacturing cost, stable in performance, high in safety, energy-saving and environment-friendly.
本发明公开了双层桥面钢桁PC组合结构桥梁及其建造方法，所述桥梁包括上层桥面板、下层桥面板、桁腹杆、上节点和下节点，桁腹杆的顶端经上节点与上层桥面板固结，桁腹杆底端经下节点与下层桥面板固结，形成双层桥面，其中上层桥面板的纵向两边开设有贯穿的支撑孔，支撑孔处预留有搭接钢筋，下层桥面板的纵向两边的顶部开设有支撑槽，支撑槽处预留有搭接钢筋，其中，上节点、下节点的加劲肋贯穿开设有钢筋孔，经钢筋孔对搭接钢筋进行搭接，然后对支撑孔和支撑槽现浇混凝土，从而固结上节点和下节点，实现了抗风性能高、自重低、造价低的双层桥面，所述桥梁提高了空间和资源利用率，结构简单、造价低、性能稳定、安全性高、节能、环保。
