Upward moving type movable formwork for continuous box girder construction
The invention discloses an upward moving type movable formwork for continuous box girder construction. The upward moving type movable formwork comprises a box girder body construction mold, a main beam, a nose beam and a rear sliding beam. The bottom of the box girder body construction mold is unfolded for box girder form removal or the bottom of the box girder body construction mold is closed so that a box girder can be poured. The main beam is supported on a middle supporting leg of the box girder and used for bearing the box girder body construction mold and driving the box girder body construction mold to move in the longitudinal direction of the box girder. The nose beam is supported on a front supporting leg of the box girder and used for guiding the main beam moving in the longitudinal direction of the box girder. The rear sliding beam is supported on the poured molded box girder and used for assisting the main beam in moving in the longitudinal direction of the box girder and being adjusted to be bent in the transverse direction of the box girder. The box girder body construction mold is suspended on the main beam, the nose beam is arranged at the advancing end of the main beam, and the rear sliding beam is arranged at the rear end of the main beam. Whole box girder pouring construction and mold movement are finished on the supporting legs and the poured molded box girder, the box girder body construction mold is opened from the bottom to form a folding span-crossing structure, and therefore the structural stability and safety of the whole formwork are guaranteed.
