Abstract
Anchor pieces (A,B) made of elongated metal plates () detachably contact each other to form an anchor (H) for a reinforcing bar (Rb) made of fiber-reinforced plastic to be used in prestressed concrete. Elongated holes () respectively extend in a width direction of each of anchor pieces at regular intervals in a longitudinal direction thereof. At least one locking half portion () is formed in each anchor piece by deforming an area (Y) between adjacent elongated holes and has a convex semicircular shape or quarter sphere shell shape. At least one annular locking portion () is formed by the at least one locking half portion of the two anchor pieces when the two anchor pieces are in contact with each other. The annular locking portion has a circular inner space in transverse cross-section and is configured to engage the reinforcing bar (Rb) when disposed therein.
