[0046] Preferably, in this embodiment, the curvature shaping plate 1 can be cut by laser according to design requirements to ensure its manufacturing accuracy.

[0047] Specifically, the positioning frame 4 includes a frame body 41 and a first horizontal stopper assembly 42. Two first horizontal stopper assemblies 42 are provided, and the two first horizontal stopper assemblies 42 are relatively arranged at the two ends of the frame body 41, and the first horizontal stopper assemblies 42 are configured to stop the rib beam side mold 3 in the first horizontal direction.
