连续纤维增强材料张紧装置、连续纤维增强材料的张紧方法及楔体
Abstract:
连续纤维增强材料张紧装置具备：按压体(50)，其将套筒(S)向固定结构物(K)侧按压，并且具有供楔体(W)沿着连续纤维增强材料(C)可往复移动自如地移动的中空部(52)；筒状的托架(21)，其相对于该按压体(52)配置于套筒(S)的相反侧，在内壁面形成有突起部；圆柱状的旋转夹具(30)，其以在托架(21)内部往复移动自如的方式设置，与楔体(W)的端面卡合，并具有与键(23)卡合的螺旋状的键槽(33)，赋予绕连续纤维增强材料(C)的轴线的旋转力；活塞(40)，其将旋转夹具(30)的端面向固定结构物(K)侧按压，由此，即使在使用了在内壁面转印有连续纤维增强材料(C)的外表面且形成有与连续纤维增强材料(C)的外表面卡合的被卡合部的楔体(W)的情况下，通过使楔体(W)沿着连续纤维增强材料(C)移动，也能够可靠地固定于固定结构物(K)。
Abstract(English):

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.
