ANCHORAGE DEVICE FOR FRP TENDON
To efficiently mount an anchorage device without damaging an FRP tendon by means of a wedge.SOLUTION: An anchorage device for an FRP tendon includes: plural holding members 2 that are pressure-welded to the outer peripheral surface of an end portion along the axis line of the FRP tendon 1; an outer pipe 3 where an end portion of the FRP tendon with the holding members pressure-welded thereto is inserted to a through-hole 3a; and wedges 4 that are press-fitted between the holding members and an inner peripheral surface of through-hole. The holding members have a length protruding to the direction in which the FRP tendon is elongated from the range where the wedges are pressure-welded, and in the tip part protruded to the direction in which the FRP tendon is elongated, adjacent holding members are coupled by a steel ring 5 to each other in a state of being arranged so as to surround the space into which the FRP tendon is inserted. A portion protruded from the range where the wedges of the holding members are engaged therein generates an elastic bending deformation slowly in the direction away from the FRP tendon by pressure-welding the wedges, and thus contact pressure relative to the FRP tendon is gradually reduced over the protruded portion.SELECTED DRAWING: Figure 1
【課題】くさびによってＦＲＰ緊張材を損傷することなく、効率よく定着装置を装着する。【解決手段】ＦＲＰ緊張材１の軸線に沿って端部の外周面に圧接される複数の把持部材２と、把持部材が圧接されたＦＲＰ緊張材の端部が貫通孔３ａに挿通される外管３と、把持部材と貫通孔の内周面との間に圧入されるくさび４と、を有する。把持部材は、くさびが圧接される範囲からＦＲＰ緊張材が伸長される方向に突き出す長さを有し、ＦＲＰ緊張材が伸長される方向に突き出した先端部は、ＦＲＰ緊張材が挿通される空間を囲むように配列された状態で隣り合う把持部材が鋼リング５によって互いに連結されている。把持部材のくさびが当接される範囲から突き出した部分は、くさびが圧接されることによってＦＲＰ緊張材から離れる方向に緩やかに弾性的な曲げ変形を生じ、突き出した部分でＦＲＰ緊張材に対する圧接力が徐々に低減される。【選択図】図１
