ANCHOR TENDON
To provide an anchor tendon which enables construction of an anchor body excellent in cut-off property and safety and is used in an anchor.SOLUTION: An anchor tendon has a plurality of tendons 2 arranged in a bundle shape and a packer 3 that surrounds the bundle of the tendons 2 and can be expanded in substantially a doughnut shape, and constitutes an anchor by being inserted to an anchor hole H so that a hole bottom side of the anchor hole H is embedded in a filler C. The packer 3 is provided so that at least the vicinity of the end on a hole port side of the anchor hole H is fixed to the bundle of the tendons 2 through a hole port side fixing material 4a, and an outer peripheral surface of a liquid leakage prevention member 5 for blocking a gap between the adjacent tendons 2 is brought into contact with an arrangement position of the hole port side fixing material 4a. The liquid leakage prevention member 5 includes a hard water cut-off member 61 brought into close contact with the tendons 2, and a cut-off buffer member 62 which is brought into contact with the hard water cut-off member 61 and the tendons 2 and is positioned between the hard water cut-off member 61 and the filler C.SELECTED DRAWING: Figure 2
【課題】止水性と安全性に優れたアンカー体を構築することの可能な、アンカーに用いるアンカーテンドンを提供する。【解決手段】束状に配置された複数の緊張材２と、緊張材２の束を囲繞し略ドーナツ形状に膨張可能なパッカー３と、を有し、アンカー孔Ｈに挿入されるとともにアンカー孔Ｈの孔底側が充填材Ｃに埋設されてアンカーを構成するアンカーテンドンである。パッカー３は、少なくともアンカー孔Ｈの孔口側の端部近傍を、緊張材２の束に孔口側固定材４ａを介して固定され、孔口側固定材４ａの配置位置に、隣り合う緊張材２間の隙間を閉塞する漏液防止部材５の外周面が接触して設けられたものである。漏液防止部材５は、緊張材２に密着させた硬質止水部材６１と、硬質止水部材６１及び緊張材２に密着し、硬質止水部材６１と充填材Ｃとの間に位置する止水性緩衝部材６２と、を備える。【選択図】図２
