Cast-in-place box girder reinforcement cage integral installation system and method
The invention provides a cast-in-place box girder steel reinforcement framework integral installation system and method.The cast-in-place box girder steel reinforcement framework integral installation system comprises a main girder arranged in the longitudinal direction of a bridge and a plurality of hoisting crown blocks, the hoisting crown blocks are arranged at the top of the main girder and walk along the main girder, and a front supporting leg, a middle supporting leg and a rear supporting leg are arranged at the bottom of the main girder; walking wheels are arranged at the bottoms of the front supporting leg, the middle supporting leg and the rear supporting leg, the front supporting leg is of a liftable and foldable or detachable structure, the middle supporting leg is of a detachable structure, and the rear supporting leg is of a liftable structure. By means of the scheme of the detachable middle supporting leg and the foldable front supporting leg, cross-span operation of the steel reinforcement framework suspended by the main beam can be achieved, the steel reinforcement framework can be taken at a time without replacing a lifting structure in the middle, transportation and installation operation of the steel reinforcement framework can be completed, and the steel reinforcement framework is even in stress and not prone to deformation in the transportation and installation process. The falling points of the front supporting legs and the rear supporting legs are ingenious, so that the stress of the whole steel reinforcement framework overall installation system is reliable.
本发明提供一种现浇箱梁钢筋骨架整体安装系统及方法，包括沿桥梁纵向布置的主梁和起重天车，起重天车为多个，布置在主梁的顶部，多个起重天车沿着主梁行走，在主梁的底部设有前支腿、中支腿和后支腿，前支腿、中支腿和后支腿的底部均设有行走轮，前支腿为可升降并且可折叠或可拆卸的结构，中支腿为可拆卸的结构，后支腿为可升降的结构。通过可拆卸的中支腿和可折叠的前支腿的方案，能够实现主梁悬吊钢筋骨架过跨运行，实现一次取钢筋骨架，中间无需更换起吊结构，即完成钢筋骨架的运输和安装操作，钢筋骨架在运输和安装过程中的受力均匀不易变形。前支腿和后支腿的落点巧妙，使整个钢筋骨架整体安装系统的受力可靠。
