ANCHORAGE OF FRP REINFORCEMENT

PROBLEM TO BE SOLVED: To stably execute an anchoring work of FRP reinforcements by fixing the FRP reinforcement so as to wrap up the outer peripheral face of the holding part of the reinforcement when introducing a tension to the FRP reinforcement to anchor it while pinching the reinforcement by an anchoring tool including a pair of wedge members and holding it. SOLUTION: An external case 1, wedge parts 2, 2', and FRP reinforcements 3 are provided. The wedge parts 2, 2' slide along the internal wall of the external case 1 by the tension at the time of anchorage, and the FRP reinforcements 3 are held on tensing the reinforcements. The FRP reinforcement 3 is constituted of reinforcing members 4, 4' and an adhesive to fix the reinforcement 3 and the reinforcing members 4, 4'. In this way, since the anchorage part of the reinforcements 3 is covered and reinforced, when a tension is introduced to the FRP reinforcement, crushing at the holding part can be prevented and the FRP reinforcement is not directly held by the wedge members. Accordingly, the reinforcement does neither slip out of the holding part nor breaks at the front end of the wedge and hence, construction work can be carried out while imparting a stable tension.
