Fabricated cantilever composite structure bridge and construction method thereof
The invention discloses a fabricated cantilever composite structure bridge and a construction method thereof. The bridge comprises a rigid transverse linkage system, a bridge deck slab and four or more parallel steel longitudinal beams. The steel longitudinal beams, the rigid transverse linkage system and the fabricated composite-structure bridge deck slab which is prefabricated according to stress distribution of the bridge and has a variable-thickness composite section are provided. Longitudinal consolidation parts consolidated with the steel longitudinal beams are pre-arranged at the longitudinal bottom of the cantilever bridge deck slab. The variable-thickness combined section is beneficial to reducing the overall self-weight of the bridge deck, the structure is light and handy, construction is convenient, and the manufacturing cost is reduced; The meshing force is improved through rabbet grooves, and the large-size rabbet grooves enable construction to be simpler and higher in efficiency, and the total manufacturing cost is saved. The cantilever bridge deck slab and the steel longitudinal beams are fixedly connected into a whole through the five longitudinal consolidation parts, so that the overall stability and safety of the bridge are improved. By means of strong longitudinal and weak transverse, transverse rabbet wet joints and longitudinal rabbet wet joints are formed, the meshing force is high, and the overall structure is stable, safe, light and high in strength.
本发明公开了装配式悬臂组合结构桥梁及其建造方法，所述桥梁包括刚性横向联结系、桥面板和并列的四个或四个以上钢纵梁，钢纵梁、刚性横向联结系和根据桥梁受力分布预制具有变厚度组合截面的装配式组合结构桥面板，悬臂桥面板的纵向底部预设有与钢纵梁固结的纵向固结部件；变厚度组合截面有利于减轻桥面板整体自重，结构轻巧，方便施工，并降低造价；通过榫口槽提高了咬合力，且大尺寸榫口槽使施工更简洁，效率更高，节省总体造价；通过五种纵向固结部件，将悬臂桥面板与钢纵梁固结为一体，提高了桥梁的整体稳定性和安全性；通过强纵弱横，形成横向榫口湿接缝和纵向榫口湿接缝，咬合力强，整体稳定、安全、轻型、高强。
