Double-amplitude cast-in-place box girder formwork and construction method
The invention provides a double-amplitude cast-in-place box girder formwork which comprises a main girder system, a plurality of suspension systems and an inner side outer formwork system, the main girder system comprises two groups of main girders and transverse connecting pieces, each suspension system comprises a cross beam, a suspended beam connecting arm and a suspended beam, one end of the suspended beam connecting arm is fixedly connected with one end of the cross beam, and the other end of the suspended beam connecting arm is fixedly connected with the other end of the cross beam. The suspended beam is located below the main beam system, and one end of the suspended beam is hinged to the other end of the suspended beam connecting arm. The inner side outer formwork system is arranged below the main beam system in the length direction of the main beam system, and the other end of the suspended beam is detachably connected with the inner side outer formwork system. The invention further provides a construction method adopting the double-amplitude cast-in-place box girder formwork. The problem that in the prior art, a post-construction box girder formwork in a double-amplitude cast-in-place box girder cannot be built through a movable formwork is solved, the construction cost is saved, and the construction efficiency is improved.
本发明提供了一种双幅现浇箱梁模架，其包括主梁系统、悬挂系统和内侧外模架系统，主梁系统包括两组主梁和横向连接件，悬挂系统有若干组，每组悬挂系统均包括横梁、挂梁连接臂和挂梁，挂梁连接臂的一端与横梁的一端固定连接，挂梁位于所述主梁系统的下方，且挂梁的一端与挂梁连接臂的另一端铰接；内侧外模架系统沿所述主梁系统的长度方向设置在所述主梁系统的下方，挂梁的另一端与所述内侧外模架系统可拆卸连接。本发明还提供了一种采用上述双幅现浇箱梁模架的施工方法。本发明解决了现有技术中双幅现浇箱梁中的在后施工箱梁模架无法采用移动模架搭建的问题，节约了施工成本，提高了施工效率。
