Prefabricated concrete shear wall connected by vertical steel bar taper sleeves and preparation method of prefabricated concrete shear wall

The invention relates to a prefabricated concrete shear wall connected through vertical steel bar taper sleeves and a preparation method. The prefabricated concrete shear wall comprises an upper-layer wall plate and a lower-layer wall plate. Crisscrossed reinforcing steel bars are arranged in the upper-layer wallboard and the lower-layer wallboard, and the crisscrossed reinforcing steel bars are vertical reinforcing steel bars and transverse reinforcing steel bars respectively; upper-layer wallboard steel bar exposed sections exposed out of the body are arranged at the two ends of the steel bars on the upper-layer wallboard, and lower-layer wallboard steel bar exposed sections exposed out of the body are arranged at the two ends of the steel bars on the lower-layer wallboard; a half-wall-thickness upper-layer positioning structure and a half-wall-thickness lower-layer positioning structure are respectively arranged at the bottom end of the upper-layer wall plate and the top end of the lower-layer wall plate,
