Variable-height corrugated web steel box-concrete continuous beam bridge and construction method
The invention belongs to the technical field of bridge engineering, and particularly relates to a variable-height corrugated web steel box-concrete continuous beam bridge and a construction method. The structure comprises middle-fulcrum variable-height corrugated web steel box beam, side-span equal-height corrugated web steel box beam and middle-span equal-height corrugated web steel box beam, theplurality of middle fulcrum variable-height corrugated web steel box beams, the side span equal-height corrugated web steel box beams and the middle span equal-height corrugated web steel box beams are connected through the inter-box steel cross beams, the middle cross beams and the end cross beams; the middle fulcrum beam bottom concrete and middle cross beam concrete are poured into the middlefulcrum variable-height corrugated web steel box beams, and end cross beam concrete is poured into the side span equal-height corrugated web steel box beams. The middle supporting point beam bottom concrete, the middle cross beam concrete and the end cross beam concrete are integrated with the middle supporting point variable-height corrugated web steel box beam and the side span equal-height corrugated web steel box beam through shear nails; the continuous beam bridge is convenient to design and construct, the steel structure and the bridge deck are reasonable in stress, and the steel box beam sections are convenient to manufacture, transport and install.
本发明属于桥梁工程技术领域，具体涉及到一种变高度波形腹板钢箱‑混凝土连续梁桥及施工方法；包括：中支点变高度波形腹板钢箱梁、边跨等高度波形腹板钢箱梁和中跨等高度波形腹板钢箱梁；多个中支点变高度波形腹板钢箱梁、边跨等高度波形腹板钢箱梁和中跨等高度波形腹板钢箱梁通过箱间钢横梁、中横梁和端横梁连接；中支点变高度波形腹板钢箱梁内灌注了中支点梁底混凝土、中横梁混凝土，边跨等高度波形腹板钢箱梁内灌注了端横梁混凝土；中支点梁底混凝土、中横梁混凝土和端横梁混凝土通过剪力钉与中支点变高度波形腹板钢箱梁和边跨等高度波形腹板钢箱梁形成整体；本发明便于设计与施工，钢结构和桥面板受力合理，钢箱梁节段制作、运输、安装方便。
