The invention discloses an assembly type shear wall bolt connection box with a stress gradient transition function, and belongs to the technical field of assembly type reinforced concrete structure connection. The connecting box comprises a steel box body, an anchoring back plate arranged on the back face of the box body and array type anchoring ribs arranged on the anchoring back plate. The metal outer wall of the connecting box is coated with a buffer layer formed by a high-strength rubber elastomer or epoxy resin mortar, and the thickness of the buffer layer is gradually reduced in the anchoring direction, so that rigidity gradient transition from the steel box to the concrete is achieved. The structure can effectively weaken stress concentration near the end of the anchor bar, delays cracking and crushing of concrete on the edge of the connecting box, remarkably improves ductility and crack resistance of the vertical abutted seam joint of the fabricated shear wall, and better achieves the design goals of strong connection and weak components.
