Abstract
The invention discloses a movable formwork suitable for multiple beams and a construction method. The movable formwork comprises main beams, a hanging bracket and a casting mold. The direction of the pair of fixedly connected main beams is identical with the length direction of a bridge. Guide beams are arranged at the front end and the rear end of each main beam. A front supporting leg, a middle supporting leg and a rear supporting leg are arranged on the bottom face of each main beam in a sliding mode. The hanging bracket is arranged on the outer sides of the two main beams. A through track beam is arranged on the bottom face of the hanging bracket. The casting mold is movably arranged on the lower side of the hanging bracket and comprises a side mold body and a bottom mold body vertically arranged on the lower side of the side mold body. Reverse hooking wheels are arranged on the upper portion of the side mold body. The cross section of the track beam is in an I shape, and the reverse hooking wheels are movably arranged in an I-shaped cavity of the track beam. By the adoption of only one movable formwork, the multiple transverse beams are cast and transversely moved; besides, the position of the movable formwork does not need to be moved in the transverse direction, materials are saved, the number of hole passing times is reduced, operation is easier, and the safety of bridge construction is improved.
