Fabricated corrugated web steel box-UHPC composite beam bridge and construction method thereof
The invention relates to a fabricated corrugated web steel box-UHPC composite beam bridge and a construction method thereof, the fabricated corrugated web steel box-UHPC composite beam bridge is composed of corrugated web steel boxes and UHPC bridge deck slabs, each corrugated web steel box is of an open box-shaped structure composed of a flat steel bottom plate, corrugated steel webs and a flat steel top plate, and the adjacent corrugated web steel boxes are connected through cross beams between the boxes; the UHPC bridge deck slabs comprise in-box prefabricated UHPC bridge deck slabs, inter-box prefabricated UHPC bridge deck slabs and cantilever cast-in-place UHPC bridge deck slabs, and the adjacent prefabricated UHPC bridge deck slabs are connected through cast-in-place wet joint UHPC bridge deck slabs; and the multiple UHPC bridge decks are correspondingly installed on the multiple corrugated web steel boxes to form the assembly type corrugated web steel box-UHPC composite beam bridge. According to the fabricated corrugated web steel box-concrete composite beam bridge, the steel consumption configuration is optimized, the self-weight of the structure is further reduced, the prefabricated concrete bridge deck is adopted, the fabricated degree is further improved, the construction period is short, the standardization degree is high, remarkable economic and social benefits areachieved, and the fabricated corrugated web steel box-concrete composite beam bridge has important significance in promoting large-scale application of steel structure bridges.
本发明涉及一种装配式波形腹板钢箱‑UHPC组合梁桥及施工方法，由波形腹板钢箱及UHPC桥面板组成，波形腹板钢箱是由平钢底板、波形钢腹板以及平钢顶板组成的开口箱形结构，相邻波形腹板钢箱通过箱间横梁连接；所述UHPC桥面板包括箱内预制UHPC桥面板、箱间预制UHPC桥面板以及悬臂现浇UHPC桥面板，相邻预制UHPC桥面板通过现浇湿接缝UHPC桥面板连接；若干UHPC桥面板对应安装于若干波形腹板钢箱上形成装配式波形腹板钢箱‑UHPC组合梁桥。装配式波形腹板钢箱‑混凝土组合梁桥优化了用钢量配置，使结构自重进一步降低，采用预制混凝土桥面板，使装配化程度进一步提高，施工周期短，标准化程度高，具有显著的经济社会效益，对推动钢结构桥梁大量应用有重要意义。
