Cast-in-place bridge deck formwork of reinforced concrete superposed beam
The invention discloses a cast-in-place bridge deck formwork of a reinforced concrete superposed beam. The formwork comprises an inter-steel-beam formwork support located between two steel box beams and a bridge deck boundary beam flange cantilever located on the outer sides of the steel box beams, the inter-steel-beam formwork support comprises main keels extending in the longitudinal bridge direction and first auxiliary keels extending in the transverse bridge direction, the main keels are parallel to one another and are sequentially arranged in the transverse bridge direction, the first auxiliary keels are parallel to one another and are sequentially arranged in the longitudinal bridge direction, the first auxiliary keels are placed on the main keels, formworks are laid on the first auxiliary keels, the formwork support between the steel beams further comprises overhanging main frameworks extending in the transverse bridge direction, the multiple cantilever main frameworks are parallel to one another and are sequentially arranged in the longitudinal bridge direction, the cantilever main frameworks are located above the formwork, the inner side flange plates of the two steel box girders support the two ends of the cantilever main frameworks through the first supporting pieces correspondingly, and the cantilever main frameworks are connected with the main keels through the multiple split bolts. The ground under the bridge does not need to be occupied, vehicles can pass under the bridge, the cost is low, the construction period is short, and efficient turnover can be achieved.
本发明公开一种钢混叠合梁现浇桥面板模架，包括位于两个钢箱梁之间的钢梁间模板支架和位于钢箱梁外侧的桥面边梁翼缘悬臂，钢梁间模板支架包括纵桥向延伸的主龙骨和横桥向延伸的第一次龙骨，多个主龙骨相互平行且沿横桥向依次排列，多个第一次龙骨相互平行且沿纵桥向依次排列，第一次龙骨放置于主龙骨上，第一次龙骨上铺设有模板，钢梁间模板支架还包括横桥向延伸的悬挑主骨架，多个悬挑主骨架相互平行且沿纵桥向依次排列，悬挑主骨架位于模板上方，两个钢箱梁的内侧翼缘板通过第一支撑件分别支撑悬挑主骨架两端，悬挑主骨架通过多个对拉螺栓连接主龙骨。不必占用桥下地面，桥下可通行车辆，低成本、施工周期短、可高效周转。
