PRETENSION TENDON, MANUFACTURING METHOD OF PRETENSION TENDON, CONSTRUCTION METHOD USING PRETENSION TENDON, AND METHOD FOR INTRODUCING PRETENSION INTO CONCRETE
PROBLEM TO BE SOLVED: To provide a pretension tendon capable of easily ensuring a pretension with a shortest fixing length required for the pretension tendon when any anchorage device is not used by using a pretension tendon of a high strength reinforcing bar (SD: 390 or more).SOLUTION: Disclosed pretension tendon S has at least one protruding bump 11 which is formed with the same material as the base material 10. The size of the tendon is 1.5 times or more in diameter of the base material 10 on the base material 10, at both end area of bar of a base material 10 (high strength reinforcing bar) to be tensioned.SELECTED DRAWING: Figure 1
【課題】高強度鉄筋（SD390以上）をプレテンション緊張材として使用し、定着装置を使用しないときに、そのプレテンション緊張材の所要定着長さの最短での確保を容易にすることのできるプレテンション緊張材の提供。【解決手段】本発明のプレテンション緊張材Ｓは、緊張する棒状の母材１０（高強度鉄筋）の端部側に、前記母材１０の周りに前記母材１０と同じ材料で前記母材１０の径より１．５倍以上大きい突形状の瘤１１を少なくとも一つ形成している。【選択図】図１
