In the pouring process of the precast box girder, the "floating up" of the inner mold of the box girder is a common phenomenon. The floating up phenomenon is easy to cause the insufficient thickness of the concrete of the top plate of the box girder, and also causes the excessive thickness of the bottom plate and the web of the box girder and the insufficient reinforcement protection layer of the top plate of the box girder, so that the design and specification requirements cannot be met, and finally the whole box girder may be scrapped, thereby causing a quality accident.

[0015] Preferably, the distance between the adjacent dovetail blocks is greater than the width of the cross beam.

[0016] By adopting the technical scheme, the distance between the adjacent dovetail blocks is greater than the width of the cross beam, so that the cross beam can directly enter the distance between the adjacent dovetail blocks, and the dovetail groove is aligned with the dovetail block, so that the dovetail groove and the dovetail block are quickly matched or disassembled.

At the same time, since the top end of the sleeve abuts against the cross beam and the bottom end of the sleeve abuts against the inner membrane, an abutting force can be generated between the cross beam and the inner membrane, preventing the inner membrane from approaching the cross beam, and ensuring the anti-floating effect of the inner membrane.
