Segmental beam wet joint steam curing device

The invention relates to the field of segmental beam wet joint steam curing, in particular to a segmental beam wet joint steam curing device which comprises segmental beam bodies, a pre-tightening assembly and a steam curing assembly are arranged between the two adjacent segmental beam bodies, and the steam curing assembly is fixed to the gap position between the adjacent segmental beam bodies through the pre-tightening assembly; according to the steam curing assembly designed in the invention, an external steam generator pumps steam into the cover plate, then the steam is jetted into a gap between the adjacent segment beam bodies from the steam holes, and the steam curing assembly in a sleeving form wraps the gap between the adjacent segment beam bodies, so that the steam curing effect is improved. At the moment, each part in the gap can be wetted and heated by the steam at the same time, so that the steam curing efficiency is improved, the curing uniformity of the contact surface of the segmental beam body
