ANCHORAGE STRUCTURE FOR TENDON

To provide an anchorage structure for a tendon that can properly hold the tendon and also improve durability of the tendon.SOLUTION: An anchorage structure 1 for a tendon 4 comprises the tendon 4 which is linear, and an anchorage module 3 which holds the tendon 4 to anchor the same to other members. The anchorage module 3 includes a first member 10, a second member 20, and a third member 30. The first member 10 is pressed against the second member 20 with tensioning force of the tendon 4 to fasten an outer peripheral surface of a first region 40A with a first inner wall surface 11. The third member 30 is supported by the first member 10 or the second member 20 in a length direction of the tendon 4, and then pressed against a second coating layer 46 on a first end face 32. A third inner wall surface 31 has lower hardness than that of a first coating layer 44, and a region of the third member 30 which comes into contact with the second coating layer 46 has higher hardness than that of the second coating layer 46.SELECTED DRAWING: Figure 3 【課題】緊張材を適切に保持することができると共に、緊張材の耐久性を向上させることができる緊張材の定着構造を提供する。【解決手段】緊張材４の定着構造１は、線状の緊張材４と、緊張材４を保持することにより他の部材に対して定着させる定着モジュール３と、を備える。定着モジュール３は、第１部材１０と、第２部材２０と、第３部材３０と、を含む。第１部材１０は、緊張材４の緊張力により第２部材２０に押し付けられることで第１領域４０Ａの外周面を第１内壁面１１によって締め付ける。第３部材３０は、緊張材４の長手方向において、第１部材１０または第２部材２０によって支持され、第１の端面３２において第２被覆層４６に押し付けられる。第３内壁面３１の硬度は第１被覆層４４の硬度よりも低く、第３部材３０の第２被覆層４６に接触する領域の硬度は第２被覆層４６の硬度よりも高い。【選択図】図３
