description The utility model discloses a precast concrete unit convenient to assemble and butt. The precast concrete unit comprises a first bridge floor, a second bridge floor, longitudinal steel bars, positioning pieces and transverse connecting bars. Wherein the two end faces of the first bridge floor and the two end faces of the second bridge floor are provided with longitudinal steel bars, the other parts of the longitudinal steel bars are pre-buried in the bridge floors, and the outer surfaces of the longitudinal steel bars outside the bridge floors are provided with external threads. Screw holes are formed in the positioning pieces, and the positioning pieces are in threaded connection with the longitudinal steel bars through the screw holes. When the first bridge deck is in butt joint with the second bridge deck, the longitudinal steel bars on the two butt joint end faces are distributed in a staggered mode, and the transverse connecting ribs are transversely distributed on the longitudinal steel bars and clamped
