Abstract: An anchoring device secures tendons formed of a filament body made of fiber reinforced plastic by inserting a male member into a female member to sandwich the tendons between them. Each of the female member and the male member is formed in a tapered shape inclined from one end toward the other end and the female member and the male member include a plurality of mount portions at predetermined intervals in a circumferential direction of an inclined tapered face between the female member and the male member, each of the plurality of tendons being placed on a different one of the mount portions. The length from the one end to the other end of each of the female member and the male member corresponding to a length direction of the tapered face in contact with the tendon is equal to or larger than 130 mm.

Abstract: [PROBLEM] To provide an anchoring device for holding and securing a plurality of tendons each formed of a filament body made of fiber reinforced plastic. [SOLVING MEANS] An anchoring device according to the present invention secures tendons formed of a filament body made of fiber reinforced plastic by inserting a male member into a female member to sandwich the tendons between them. Each of the female member and the male member is formed in a tapered shape inclined from one end toward the other end and the female member and the male member include a plurality of mount portions at predetermined intervals in a circumferential direction of an inclined tapered face between the female member and the male member, each of the plurality of tendons being placed on a different one of the mount portions. The length from the one end to the other end of each of the female member and the male member corresponding to a length direction of the tapered face in contact with the tendon is equal to or larger than 130 mm.
