Concrete box girder moving formwork left-right transverse moving device and moving method thereof

LIN JIMING

The invention relates to the field of cast-in-place concrete box girders, in particular to a concrete box girder moving formwork left-right transverse moving device and a moving method thereof.The concrete box girder moving formwork left-right transverse moving device at least comprises a moving cross beam and protruding sliding faces located on the two sides of the ground of the moving cross beam and further comprises a transverse moving platform; the first rail is detachably connected to the transverse moving platform and arranged in the length direction of the transverse moving platform; the second rail is detachably connected to the center of the lower surface of the movable cross beam; a pair of sliding seats is connected to the first rail in a sliding mode, and the cross beam is connected to the pair of sliding seats in a sliding mode through a pair of sliding faces respectively. The transverse moving platform is erected between the pier columns, the bearing effect on the movable cross beam during formwork erecting can be achieved, meanwhile, movable erecting is adopted, only one-time hoisting is needed, and erecting can be conducted by transversely moving the movable cross beam on the other side.

本发明涉及现浇混凝土箱梁领域，具体涉及一种混凝土箱梁移动模架左右幅横移装置及其移动方法，至少包括移动横梁和位于移动横梁地面两侧凸起的滑面，还包括：横移平台；轨道一，该轨道一可拆卸连接在横移平台上，且以横移平台长度方向设置；轨道二，该轨道二可拆卸连接在移动横梁下表面中心处；滑座，所述轨道一上滑动连接一对滑座，所述横梁通过一对滑面分别滑动连接在一对滑座上。本发明通过在墩柱之间架设横移平台，可起到在支模时对移动横梁的承载作用，同时采用移动式架设，只需进行一次吊装，另一侧通过对移动横梁进行横移即可进行架设。
