Composite beam bridge and construction method
The invention discloses a composite beam bridge and a construction method, the composite beam bridge comprises a bridge deck structure and a pier cover beam, and the bridge deck structure is formed by connecting a plurality of steel structure composite beams; the bridge deck structure and the pier bent cap are connected through a supporting system, and the supporting system comprises a simply-supported bridge deck continuous supporting structure and a bridge structure continuous supporting structure. The steel structure composite beam comprises a bridge deck slab and a steel structure which are connected with each other, the steel structure comprises a lower flange plate and a web plate, and the web plate is directly connected with the bridge deck slab through a mortise and tenon joint structure. And the lower flange plate and the web plate are connected with each other through welding. The composite beam bridge has the advantages of being small in bridge deck slab size, low in self weight, high in spanning capacity and light in weight, on-site construction work can be reduced to the maximum extent, industrial production and rapid assembly construction are achieved, and construction efficiency is improved. And meanwhile, by optimizing the steel structure composite beam, the manufacturing cost of the composite beam is reduced, and the rigidity of the joint and the shearing force transmission efficiency are improved.
本发明公开了一种组合梁桥及施工方法，组合梁桥包括桥面结构和桥墩盖梁，桥面结构由若干钢结构组合梁连接形成；桥面结构和桥墩盖梁之间通过支承体系实现连接，所述支承体系包括简支桥面连续支承结构和桥梁结构连续支承结构；所述钢结构组合梁包括互相连接的桥面板和钢结构，所述钢结构包括下翼缘板和腹板，所述腹板与桥面板之间通过榫卯结构直接连接；所述下翼缘板与腹板之间通过焊接实现相互连接。本发明的组合梁桥具有较小的桥面板尺寸，自重低、跨越能力强，具有轻型化的优势，可以最大限度减少现场的施工作业，实现工业化生产和快速装配施工，同时通过对钢结构组合梁的优化降低了组合梁的造价、提升了连接处的刚度以及传递剪力的效率。
