The invention relates to a fabricated concrete double-T-plate abutted seam bolt connection structure, aims to solve the problem of abutted seam connection of double-T-plate flanges in a fabricated building large-span floor (roof) structure system, and belongs to the technical field of structural engineering. The connection structure comprises two T-shaped steel plates, anchor bars welded to the T-shaped steel plates, connecting steel plates used for fixing the two T-shaped steel plates, high-strength bolts and circular washers; each double-T-plate flange comprises a layer of reinforcing mesh formed by laying longitudinal and transverse reinforcing steel bars and a rectangular notch located in the side edge of the plate and facilitating installation of a bolt connecting piece; and concretelaminated layers are poured on the upper portions of the the double T-shaped plate flanges and the bolt connecting pieces, and the connecting performance of the abutted seams and the overall performance of the double T-shaped
