FRP TENDON FIXATION METHOD AND FRP TENDON FIXATION STRUCTURE
To enable a filler to be charged across an entire length of a tendon insertion hole of a precast member on which the tendon insertion hole having length disallowing a shrinkage-compensating mortar to be charged is formed.SOLUTION: A fixation method of an FRP tendon (3) in a pre-stressed concrete member (1) includes a first injection step to inject a first filler (5) for fixing the FRP tendon to a precast member (2) to a first end section S1 on one end side in a longer direction of a tendon insertion hole 4, a second injection step to inject a second filler (6) having higher fluidity than the first filler to a central section S2 positioned at a center in the longer direction of the tendon insertion hole, and a third injection step to inject the first filler to a second end section S3 on the other end side in the longer direction of the tendon insertion hole.SELECTED DRAWING: Figure 4
【課題】無収縮モルタルを充填できない長さの緊張材挿通孔が形成されたプレキャスト部材の緊張材挿通孔に、全長に亘って充填材を充填できるようにする。【解決手段】プレストレストコンクリート部材（１）におけるＦＲＰ緊張材（３）の定着方法は、緊張材挿通孔４の長手方向の一端側の第１端部区間Ｓ１に、ＦＲＰ緊張材をプレキャスト部材（２）に定着させるための第１充填材（５）を注入する第１注入ステップと、緊張材挿通孔の長手方向の中央に位置する中央区間Ｓ２に、第１充填材よりも流動性が高い第２充填材（６）を緊張材挿通孔に注入する第２注入ステップと、緊張材挿通孔長手方向の他端側の第２端部区間Ｓ３に、第１充填材を注入する第３注入ステップとを含む。【選択図】図４
