Prestressed anchor plate

The utility model discloses a pre-stressed anchor plate which is used for being matched with a conical clamping piece to anchor a pre-stressed tendon with a break angle and comprises a through hole used for penetrating through the pre-stressed tendon, and the through hole comprises a conical hole section, a straight barrel section and a diverging section. The conical hole section is used for being matched with a conical clamping piece; one end of the straight tube section is communicated with the small end of the taper hole section, and the other end of the straight tube section is communicated with the small end of the diverging section; the divergent section comprises a fillet or one of at least two continuously connected chamfers; wherein the sum of the angles of the chamfers is smaller than the break angle of the prestressed tendon. According to the pre-stressed anchor plate, stress concentration at the contact position of the bending position of the pre-stressed tendon and the anchor plate can be effecti
