TENSION DEVICE AND TENSION METHOD OF TENDON
To provide a tension device and tension method of a tendon suppressing an increase in device size and not requiring a large working space.SOLUTION: A tension device comprises: a plurality of elongated members 7 having threads on an outer peripheral surface and connected to a tendon 3 in series along a tension direction; a connecting tool 8 detachably connecting neighboring elongated members 7 with each other and having an outer contour located inside an outer contour of the elongated member 7 when viewed from the tension direction; a ram chair 9 supported by a concrete frame 2; a first nut 10 screwed with the outer peripheral surface of the elongated member 7 and capable of being locked to the ram chair 9; an additional ram chair 11 supported by the ram chair 9; a jack 12 supported by the additional ram chair 11; and a second nut 14 screwed with the outer peripheral surface of the elongated member 7 and capable of being locked to a displacement portion 12b of the jack 12. The first nut 10 and the second nut 14 can slide the connecting tool 8 in the tension direction.SELECTED DRAWING: Figure 1
【課題】装置の大型化が抑制され、大きな作業スペースを必要としない緊張材の緊張装置及び緊張方法を提供する。【解決手段】緊張装置は、外周面にねじを有し、前記緊張方向に沿って直列に緊張材３に連結された複数の長尺部材７と、互いに隣接する長尺部材７を互いに取り外し可能に接続し、緊張方向から見て長尺部材７の外輪郭の内側に位置する外輪郭を有する接続具８と、コンクリート躯体２に支持されたラムチェア９と、長尺部材７の外周面に螺合してラムチェア９に係止され得る第１ナット１０と、ラムチェア９に支持された追加ラムチェア１１と、追加ラムチェア１１に支持されたジャッキ１２と、長尺部材７の外周面に螺合してジャッキ１２の変位部１２ｂに係止され得る第２ナット１４とを備える。第１ナット１０及び第２ナット１４は、接続具８を緊張方向にスライド移動可能である。【選択図】図１
