ANCHORAGE DEVICE, AND PC STEEL TWISTED WIRE WITH ANCHORAGE DEVICE
To provide an anchorage device capable of being installed at an end portion in a longer direction of a PC steel twisted wire with a coating, without removing the coating.SOLUTION: An anchorage device 30 is installed at one end portion in a longer direction of a PC steel twisted wire with a coating, has a cylindrical shape, and comprises a recessed portion and a protruding portion in an inner peripheral surface 33. The recessed portion and the protruding portion are respectively provided in a linear shape along a peripheral direction of the inner peripheral surface. In a cross section passing a central axis CA of the anchorage device, a curvature radius of the recessed portion is 0.1 mm to 2.0 mm.SELECTED DRAWING: Figure 3
【課題】被覆付きＰＣ鋼撚り線の長手方向の端部に、被覆を除去することなく設置できる定着具を提供する。【解決手段】被覆付きＰＣ鋼撚り線の長手方向の一方の端部に設置する定着具３０であって、定着具は円筒形状であり、かつ内周面３３に凹部、および凸部を備えており、凹部、および凸部は、それぞれ内周面の周方向に沿って線状に設けられており、定着具の中心軸ＣＡを通る断面において、凹部の曲率半径が０．１ｍｍ以上２．０ｍｍ以下である。【選択図】図３
