Steel-bamboo-concrete combined box girder and construction method thereof
The steel-bamboo-concrete combined box girder comprises a steel inner structure frame, a bamboo outer structure frame and a UHPC concrete bridge deck, the steel inner structure frame is wrapped with the bamboo outer structure frame, and the bamboo outer structure frame and the steel inner structure frame are fixedly connected to form an integrated bamboo-steel box girder with an opening in the top. The side wall of the integrated bamboo steel box girder extends in a wave shape in the longitudinal direction, the UHPC bridge deck is supported on the top of the integrated bamboo steel box girder, the transverse section of the bamboo outer structure frame is in a U shape, the bamboo outer structure frame comprises a bamboo bottom plate, two wave-shaped bamboo webs and prestressed tendons, the two wave-shaped bamboo webs are oppositely arranged on the two transverse sides of the bamboo bottom plate, and the two wave-shaped bamboo webs are arranged on the two longitudinal sides of the bamboo bottom plate. The prestressed tendons are tensioned on the bamboo bottom plate in the longitudinal direction, the bottom of the steel internal structure frame is supported on the bamboo bottom plate, and the side face of the steel internal structure frame is fixedly connected with the bamboo web. According to the steel-bamboo-concrete combined box girder, the dead weight of the girder body is reduced, the proportion of dead load borne by the girder is reduced, and corrosion of the steel webs is reduced.
本发明公开了一种钢‑竹‑混凝土组合箱梁及其施工方法，包括钢内构框架、竹外构框架以及UHPC混凝土桥面板，竹外构框架包覆钢内构框架设置，竹外构框架与钢内构框架固定连接形成顶部开口的集成竹钢箱梁，集成竹钢箱梁的侧壁沿纵向呈波浪形延伸设置，UHPC混凝土桥面板支承在集成竹钢箱梁的顶部，竹外构框架的横向截面形状呈U形，竹外构框架包括竹底板、波形竹腹板以及预应力筋，两个波形竹腹板相对地设于竹底板的横向两侧，预应力筋沿纵向张紧在竹底板上，钢内构框架的底部支撑在竹底板上，钢内构框架的侧面与竹腹板固定连接。本发明的钢‑竹‑混凝土组合箱梁，减轻了梁体自重，减少梁承受自重荷载比例，并且减少钢腹板的锈蚀。
