FIXATION METHOD OF TENDON, TENSILE FORCE ADJUSTMENT METHOD OF TENDON AND JACK DEVICE
To easily conduct fixation compensating for a reduction of tensile force caused by a pressure reduction after the fixation by a fixation tool.SOLUTION: The invention is a fixation method of a tendon using a jack device having a ram chair and comprises following processes. It comprises a process of fixing the tendon to the jack device so as to insert through the inside of the ram chair in a first state not abutting on a bearing plate, a first fixation process of fixing the tendon to the bearing plate through a fixation tool while applying pressure by the jack device and pulling the tendon, and depressurizing the tensile force of the jack device to the tendon fixed by the fixation tool, a process of moving the ram chair in the first state and abutting it on the bearing plate and a second fixation process of reapplying pressure to the jack device in the state where the ram chair is abutted on the bearing plate to separate the fixation tool from the bearing plate and fixing the fixation tool to the bearing plate in the state of being separated from the bearing plate.SELECTED DRAWING: Figure 1
【課題】定着具による定着後の減圧で生じる緊張力の減少に対する補完定着を容易に行う。【解決手段】本発明は、ラムチェアを備えたジャッキ装置を用いた緊張材の定着方法であり、以下の工程を含む。支圧板に当接しない第１の状態のラムチェア内側を挿通するように、緊張材をジャッキ装置に固定する工程、ジャッキ装置で加圧して緊張材を引っ張りながら定着具を介して支圧板に定着し、定着具によって定着された緊張材に対するジャッキ装置の緊張力を減圧する１次定着工程、第１の状態のラムチェアを移動させて支圧板に当接する工程、及びラムチェアを支圧板に当接させた状態でジャッキ装置を再度加圧して支圧板から定着具を離間させ、支圧板から離間した状態で定着具を支圧板に固定する２次定着工程。【選択図】図１
