[0002] As a new type of girder, the U - shaped trough girder has the advantages of low construction height, good noise reduction effect, beautiful appearance, good visual effect, etc. It is gradually replacing the traditional box girder structure form and becoming the main structure form of the viaduct system for rail transit, especially urban rail transit.

[0003] Chinese Patent Publication No. CN212826017U discloses a trough - type precast segmental girder formwork, which includes an inner formwork, side formworks, a bottom formwork and end formworks. The inner formwork is composed of a left inner formwork, a right inner formwork, a lower inner formwork, vertical connecting rods and a support cross - beam. The left inner formwork, the right inner formwork and the lower inner formwork are hinged. Adjusting lead screws are symmetrically arranged between the left inner formwork, the right inner formwork and the lower inner formwork. The inner formwork and the vertical connecting truss are fixed by welding. The vertical truss connecting rod and the anti - floating cross - beam support are fixedly connected by bolts. Both ends of the anti - floating cross - beam are bolt - connected to the side formworks, and the middle of the anti - floating cross - beam is bolt - connected to the inner formwork truss. Adjusting lead screws are arranged at the lower ends of the left side formwork and the right side formwork. The left side formwork and the right side formwork are connected to the bottom formwork through formwork anti - floating buckles.

During the movement operation of the top beam formwork assembly 2, the support formwork 5 is driven to move, so as to demold the left and right sides of the segment beam workpiece 1. Furthermore, the clamping formwork 7 is installed on the front and rear sides of the segment beam workpiece 1, and its movement will demold the front and rear sides of the segment beam workpiece 1.
