PRESTRESSING STEEL PROTECTION SHEATH WITH SENSOR, AND METHOD OF MANUFACTURING THE SAME
PROBLEM TO BE SOLVED: To enable a sensor to be protected from concrete pressure while the sensor can be attached from the outside.SOLUTION: A sheath body 2, which is molded in a spiral irregular shape, into which prestressing steel is inserted and into which grout is injected, is provided with a filling sensor 10 for detecting grout filling conditions. At least a tip side of the filling sensor 10 is covered from the outside with a cover part 11a of a sensor cover 11 integrated with the sheath body 2, and wiring 10b is extended from a back end side.
【課題】センサを外側から取り付けできるようにしながらも、コンクリートの圧力から守ることができるようにする。【解決手段】螺旋状の凹凸形状に成形され、内部にＰＣ鋼材が挿入され、グラウトが注入されるシース本体２に、グラウトの充填状況を検知する充填センサ１０を設ける。この充填センサ１０の少なくとも先端側をシース本体２に一体化したセンサカバー１１のカバー部１１ａで外側から覆い、後端側から配線１０ｂを延ばす。【選択図】図１
