Self-resetting energy consumption connecting device for fabricated shear wall

The invention discloses a self-resetting energy consumption connecting device for a fabricated shear wall. The self-resetting energy consumption connecting device comprises energy consumption connecting pieces which are symmetrically arranged at bottom corners of two ends of a prefabricated wall plate, an upper wall plate and a lower wall plate are connected into a whole through a prestress system, the energy consumption connecting pieces comprise two replaceable plates, the two replaceable plates are vertically and symmetrically arranged on the inner surface and the outer surface of the upperwall plate, a plurality of bolt holes are vertically formed in the two ends of the replaceable plates, screw rod through holes are correspondingly formed in the upper wall plate, bolt rods sequentially penetrate through the bolt holes and the screw through holes to connect the two replaceable plates and the upper wall plate together, and the bolt rods can slide up and down in the bolt holes and the bolt through holes.
