CONTINUOUS FIBER-REINFORCED MATERIAL TENSIONING DEVICE, TENSIONING METHOD FOR CONTINUOUS FIBER-REINFORCED MATERIAL, AND WEDGE BODY

WIPO Patent Application WO/2016/203649

A1

This continuous fiber-reinforced material tensioning device is provided with: a pressing body 50 that presses a sleeve S toward a fixed structure K and has a hollow part 52 in which a wedge body W is movable so as to freely reciprocate along a continuous fiber-reinforced material C; a tubular bracket 21 that is arranged on the side opposite to the sleeve S with respect to the pressing body 50 and has a protruding part on an inner wall face thereof; a columnar rotation jig 30 that is disposed so as to freely reciprocate inside the bracket 21, engages with an end face of the wedge body W, has a spiral key way 33 engaging with a key 23, and applies a rotation force about an axis of the continuous fiber-reinforced material C; and a piston 40 that presses an end face of the rotation jig 30 toward the fixed structure K. Thus, even when the wedge body W to be used has an inner wall face to which an outer face of the continuous fiber-reinforced material C is transferred, and has an engaged part formed therein engaging with the outer face of the continuous fiber-reinforced material C, the wedge body W can be securely anchored to the fixed structure K by moving the wedge body W along the continuous fiber-reinforced material C.
