Double-T-plate abutted seam wet type connection node structure

The utility model relates to the technical field of fabricated buildings, and discloses a double-T plate abutted seam wet-type connecting node structure which comprises two double-T plate units, grooves are formed in the connecting ends, close to each other, of the two double-T plate units, and the two grooves are spliced to form a connecting groove used for cast-in-place concrete. First steel bars transversely extending into the grooves are further arranged in the double-T plate units, second steel bars transversely extending are further arranged in the connecting grooves, and the first steel bars are in lap joint with the second steel bars. A sealing unit is further included, and the sealing unit is arranged at the connecting position of the two grooves. The groove bottom of the groove can be used as a template for cast-in-place concrete, so that the processes of supporting and removing the template are omitted, the processes of binding reinforcing steel bars, pouring concrete and maintaining the cast-in-pl
