Abstract:
PROBLEM TO BE SOLVED: To provide a cutoff structure of an anchor structure, which has a smaller outer diameter in the state in which a plurality of cutoff portions are bound together, and facilitates driving of the anchor structure.
SOLUTION: The anchor structure is formed of a plurality of tendons inserted into a bored hole, and an anchorage device fixing the tendons together at an end of the bored hole. Then grout is filled in a gap between the bored hole and the tendons. A free length portion which is partitioned from the grout is formed on one end side of the tendon, and the tendons 21 and a fixed length portion which is anchored by the grout is formed on the other side of the tendon. Further a boundary between the free length portion and the fixed length portion of each tendon 21 is cut off by the cutoff portions 90. At this time at least some of the cutoff portions 90 formed at the respective tendons 21 are arranged in a manner being deviated from the remaining ones of the cutoff portions in a longitudinal direction of the tendons 21.
