PROBLEM TO BE SOLVED: To provide a tendon tensioning method, a tendon tensioning device and a tendon tensioning system constructing an anchor structure with high working efficiency while improving the reliability of the anchor structure. SOLUTION: A multi-tensioning device 1 capable of batch-tensioning tendons 200 is disposed at a plurality of tendons 200 projected from one anchor disk 110 (an anchor board). A single tensioning device 2 capable of tensioning only one tendon is disposed at one tendon 200a out of the tendons 200 projected from the rear end of the multi-tensioning device 1, in series with the multi-tensioning device 2. The tendon 200a is tensioned by the single tensioning device 2 and temporarily fixed in the looseness reduced state of the tendon 200a. After tensioning by the single tensioning device 2, the plurality of tendons 200 are simultaneously tensioned and fixed to the anchor disk 110. COPYRIGHT: (C)2010,JPO&INPIT |
