METHOD FOR TENSIONING TENDON, AND TENSION UNIT
PROBLEM TO BE SOLVED: To provide a method for tensioning a tendon for reducing friction loss that occurs in a contact part between the tendon and a concrete member.SOLUTION: A method for tensioning a tendon 12 arranged along a beam member to introduce prestress into the beam member includes: an initial tensioning step of pulling the side of one end of the tendon 12 having the side of the other end fixed to the beam member; a partial tensioning step of pulling the side of one end of the tendon 12 in the state of restraining a restraining part 12H between the side of one end of the tendon 12 and the side of the other end thereof; and an excitation step of axially vibrating the tendon 12 by releasing restraint of the restraining part 12H.
【課題】緊張材とコンクリート部材との接触部に発生する摩擦損失を低減する緊張材の緊張方法を提供する。【解決手段】梁部材に沿って配置され、梁部材にプレストレスを導入する緊張材１２の緊張方法は、一端側が梁部材に固定された緊張材１２の他端側を引っ張る初期緊張工程と、緊張材１２における一端側と他端側との間の拘束部１２Ｈを拘束した状態で、緊張材１２の他端側を引っ張る一部緊張工程と、拘束部１２Ｈの拘束を解除し、緊張材１２を軸方向に振動させる加振工程と、を備えている。【選択図】図５
