Top plate #-shaped rib stiffening corrugated steel web combined box girder with inclined struts and construction method
The invention discloses a top plate #-shaped rib stiffening type corrugated steel web combined box girder with inclined struts and a construction method of the top plate #-shaped rib stiffening type corrugated steel web combined box girder. The box girder comprises a concrete top plate, a concrete bottom plate, corrugated steel web assemblies, steel pipe concrete inclined struts and inclined strut connecting pieces. The concrete top plate is of a #-shaped rib stiffening structure, and anchor beams are arranged at the transverse outer ends of cantilever flanges of the concrete top plate. The corrugated steel web assembly is longitudinally arranged between the concrete top plate and the concrete bottom plate; anchor blocks are arranged at the two transverse ends of the concrete bottom plate; the concrete filled steel tube inclined struts are longitudinally arranged and connected to the anchor beams and the anchor blocks through inclined strut connecting pieces. The design width of the box girder top plate can be increased by adopting the inclined struts, the material consumption of the bridge is reduced, the transverse and longitudinal flexural rigidity of the top plate is improved by combining the #-shaped rib stiffening type top plate, and better structural stability and economic benefits are obtained. The arrangement of the corrugated steel webs and the inclined struts accelerates and promotes the development of the bridge in the long-span, wide-bridge-floor and light-weight directions, and has wide application prospects.
本发明公开了一种带斜撑的顶板井字肋加劲式波形钢腹板组合箱梁及其施工方法。该箱梁包括混凝土顶板、混凝土底板、波形钢腹板组件、钢管混凝土斜撑和斜撑连接件；所述混凝土顶板为井字肋加劲结构，其悬挑翼缘横外端设置有锚梁；混凝土顶板和底板平行设置，之间纵向设置波形钢腹板组件；所述混凝土底板横向两端设置有锚块；所述钢管混凝土斜撑纵向设置，通过斜撑连接件连接到锚梁和锚块。本发明采用斜撑可增大箱梁顶板设计宽度，并减小桥梁的材料用量，结合井字肋加劲式顶板提高顶板横向和纵向的抗弯刚度，获得了更好的结构稳定性和经济效益。波形钢腹板和斜撑的设置加速推进桥梁向长跨径、宽桥面、轻型化方向发展，具有广阔的应用前景。
