Anti-seismic fabricated embedded part

The anti-seismic fabricated embedded part comprises a steel plate part, an anchoring component, a positioning plate part and a fixing component, the anchoring component is fixedly connected to the outer surface of the steel plate part, the length direction of the anchoring component is perpendicular to the outer surface of the steel plate part, and the anchoring component is of a hollow structure; the outer surface of the positioning plate abuts against the outer wall of the side, away from the anchoring component, of the steel plate. The connecting mode that the screw pieces screwed inwards serve as the anchor bars and the curtain wall keel lap joint frame is adopted, a traditional welding connecting mode is replaced, potential safety hazards existing in curtain wall construction are greatly reduced, meanwhile, good durability and shock resistance are achieved, the curtain wall connecting strength is high, the deformation bearing capacity of the connecting pieces is high, and the service life of the connecti
