TENSION FIXING DEVICE FOR PC STEEL AND TENSION FIXING METHOD FOR PC STEEL
To tension PC steel with specified tensioning force in a narrow working space with easy operation.SOLUTION: A tension fixing device 1000 includes a tensioning jack 1400 for tensioning a PC steel 210 using a tensioning fixture 1100, and a press-fitting jack 1500 for press-fitting a wedge 1210 of a fixing fixture 1200. The press-fitting jack 1500 is encased in a frame 1420 of the tensioning jack 1400 in a cross section including the central axis of the PC steel 210, and an overlap portion of a tensioning piston 1410 of the tensioning jack 1400 and a press-fitting piston 1510 of the press-fitting jack 1500 in the longitudinal direction of the PC steel 210 (L(1) and L(2) overlap) is provided.SELECTED DRAWING: Figure 3
【課題】狭小作業空間においても容易な作業でＰＣ鋼材を規定の緊張力で緊張させる。【解決手段】緊張定着装置１０００は、緊張用定着具１１００を用いてＰＣ鋼材２１０を緊張する緊張用ジャッキ１４００と、固定用定着具１２００のウェッジ１２１０を圧入する圧入用ジャッキ１５００とを含み、ＰＣ鋼材２１０の中心軸を含む断面において、緊張用ジャッキ１４００のフレーム１４２０に圧入用ジャッキ１５００が内包されるとともに、緊張用ジャッキ１４００の緊張用ピストン１４１０と圧入用ジャッキ１５００の圧入用ピストン１５１０とがＰＣ鋼材２１０の長手方向において重なり合う（Ｌ（１）とＬ（２）とが重なり合う）部分を備える。【選択図】図３
