Cast-in-place box girder sinking type integral formwork system and construction method
The invention belongs to a cast-in-place box girder sinking type integral formwork system and a construction method, the cast-in-place box girder sinking type integral formwork system is composed of a cast-in-place box girder translation frame, a lifting device and a sinking type integral formwork system, and the sinking type integral formwork system comprises two side formworks, a bottom formwork and an inner formwork. The translation frame system comprises a plurality of top longitudinal beams, upper top longitudinal beams and top cross beams. And the lifting device is used for suspending and lifting the sinking type integral template system at the front part of the translation frame of the cast-in-place box girder. The device can replace a traditional hanging basket to carry out cantilever casting construction of the cast-in-place box girder, traditional cantilever hanging basket construction is removed, the defect of hanging basket construction is overcome, and the device has the advantages that the overall arrangement speed is high, the speed of moving towards the next to-be-cast box girder construction space is high, damage to the overall structure of a bridge floor is small, the working procedure is simple, and time and labor are saved.
本发明属于一种现浇箱梁下沉式整体模板系统及施工方法，由现浇箱梁的平移架、升降装置、下沉式整体模板系统所构成，下沉式整体模板系统包括两块侧模板、一块底模板和内模板。平移架系统包括若干根顶纵梁、上顶纵梁和顶横梁。升降装置用于在现浇箱梁的平移架前部悬吊升降下沉式整体模板系统。本发明能替代传统挂篮进行现浇箱梁的悬浇施工，去掉了传统悬臂挂篮施工，也不存在用挂篮施工的不足，具有整体布设速度快，向下一个待浇箱梁施工空间内移动速度快、对桥面整体结构损伤少、工序简单、省时省力的优点。
