FRP TENDON FIXATION METHOD AND FRP TENDON FIXATION STRUCTURE
To enable a filler to be charged across entire length of a tendon insertion hole having length disallowing a shrinkage-compensating mortar to be charged.SOLUTION: A fixation method of an aramid FRP tendon 3 in a pre-stressed concrete member (1) includes the steps of injecting a partition wall filler (5) to construct a first partition wall 6A at a predetermined position from a left end 4a of a tendon insertion hole 4, injecting the partition wall filler to construct a second partition wall 6B at a predetermined position from a right end 4b of the tendon insertion hole 4, injecting a first filler (7) for fixing the FRP tendon to a precast member (2) to a first end section S1 from one end (4a) of the tendon insertion hole 4 to the first partition wall, injecting a second filler (8) to a central section S3 from the first partition wall to the second partition wall, and injecting the first filler to a second end section S2 from the other end (4b) of the tendon insertion hole 4 to the second partition wall.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）におけるアラミドＦＲＰ緊張材３の定着方法は、緊張材挿通孔４の左端４ａから所定の位置に第１仕切り壁６Ａを構築するべく仕切り壁用充填材（５）を注入するステップと、緊張材挿通孔４の右端４ｂから所定の位置に第２仕切り壁６Ｂを構築するべく仕切り壁用充填材を注入するステップと、緊張材挿通孔４の一端（４ａ）から第１仕切り壁までの第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（７）を注入するステップと、第１仕切り壁から第２仕切り壁までの中央区間Ｓ３に第２充填材（８）を注入するステップと、緊張材挿通孔４の他端（４ｂ）から第２仕切り壁までの第２端部区間Ｓ２に第１充填材を注入するステップとを含む。【選択図】図４
