Translation formwork system of cast-in-place box girder and construction method of translation formwork system
The invention belongs to a translation template system of a cast-in-place box girder and a construction method thereof, the translation template system of the cast-in-place box girder is composed of a translation frame system of the cast-in-place box girder and a template system on the translation frame system of the cast-in-place box girder, a traditional hanging basket is replaced to carry out cantilever casting construction of the cast-in-place box girder, traditional cantilever hanging basket construction is removed, and the defect of hanging basket construction is overcome. When the cast-in-place box girder is subjected to suspension casting construction, the translation formwork system of the cast-in-place box girder serves as an integral suspension casting system of all parts and formworks of the cast-in-place box girder, and then when the next to-be-cast box girder is subjected to suspension casting, the translation formwork system of the cast-in-place box girder is integrally translated into the construction space of the next to-be-cast box girder. The folding type side formworks and the side wing formworks can be located at the set positions on the hanging frame body by adjusting the distances between the formwork telescopic screws, the inclined telescopic screws and the limiting sliding rods in the ball head seats and the corresponding screw hole seats or the sliding rod seats, and therefore the hanging frame can be conveniently suitable for cast-in-place construction of cast-in-place box girders with different section sizes; the device has the advantages of high moving speed, less damage to the overall structure of the bridge floor, simple process, time saving and labor saving.
本发明属于一种现浇箱梁的平移模板系统及其施工方法，由现浇箱梁的平移架系统和其上的模板系统所构成，本发明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。现浇箱梁的悬浇施工时，现浇箱梁的平移模板系统是作为现浇箱梁悬浇各部件和模板的整体悬浇系统，而后在悬浇筑下一个待浇箱梁时，现浇箱梁的平移模板系统整体平移至下一个待浇箱梁施工空间内。本发明可以通过调整各模板伸缩螺杆、斜伸缩螺杆和限位滑杆在各球头座与对应的螺孔座或滑杆座内的距离，使折叠式侧模板和侧翼模板处于悬挂架体上的设定位置，因而本发明可以方便适合不同截面尺寸现浇箱梁的现浇施工,具有移动速度快、对桥面整体结构损伤少、工序简单、省时省力的优点。
