Base plate and prestressed system anchoring end structure thereof

The utility model discloses a base plate and a prestressed system anchoring end structure thereof, which comprise two semicircular base plates with the same size, a cylindrical through hole is arranged in the middle of each semicircular base plate, a concave staggered platform is arranged on the top plane of each semicircular base plate, and a convex staggered platform is arranged on the bottom plane of each semicircular base plate. The two semicircular base plates are detachably and fixedly connected; according to the scheme, the transverse integrity of the base plate is improved through transverse connecting measures (the trapezoidal blocks, the tenons and the notches); due to longitudinal limiting measures (slab staggering), the anchor ring, the base plate, the anchor base plate and the flange have certain integrity in the longitudinal direction (the prestress tensioning direction); staggered platforms need to be arranged at the top and the bottom, the upper structure and the lower structure of the base pl
