Abstract

The utility model discloses an automatic side formwork device for prefabricating a high-speed rail box girder, which comprises a side formwork mechanism, a side formwork mechanism, a side formwork mechanism, a side formwork mechanism and a side formwork mechanism, and the side formwork mechanism comprises a side formwork flange plate part and a side formwork web plate part which are connected together; the supporting trusses are symmetrically arranged on the two outer sides of the bottom of the side mold mechanism; the side formwork supporting mechanisms are longitudinally arranged on the two outer sides of the side formwork mechanism at intervals, each side formwork supporting mechanism comprises at least two length-adjustable side formwork adjustable supporting rods, one end of each side formwork adjustable supporting rod supports the corresponding side formwork flange plate part and the corresponding side formwork web plate part, and the other end of each side formwork adjustable supporting rod is connected with the supporting truss; the lifting mechanisms are longitudinally arranged below the supporting truss at intervals, and the upper ends of the lifting mechanisms are connected with the supporting truss in a lifting mode. When the box girder prefabricating device is used for prefabricating the box girder, the adjusting precision after the side mold is assembled can be improved, and integrated automatic demolding can be realized.
