Continuous fiber reinforcing material tension apparatus, continuous fiber reinforcing material tension method, and wedge body

摘要

The continuous fiber reinforcing material tension apparatus includes a pressing body that presses a sleeve to a side of a fixed structure and contains a hollow portion, in which a wedge body is allowed to reciprocate along a continuous fiber reinforcing material, a cylindrical bracket located in an opposite side of the sleeve from the pressing body and having an inner wall surface on which a projection is formed, a columnar rotary jig that is allowed to reciprocate inside the bracket, that engages with an end face of the wedge body, that has a spiral key groove that engages with a key, and that applies rotative force around an axis of the continuous fiber reinforcing material, and a piston that presses an end face of the rotary jig to a side of the fixed structure.
