To provide a tension type ground anchor preventing a pull-out and reducing a workload in processing a tension member and applying tension during a construction in an economical way even when the number of cross sections (the number of wires) of PC steel stranded wires appearing on a cross section perpendicular to a longitudinal direction is an odd number.SOLUTION: A tension anchor comprises a plurality of tension members 2 made of PC steel stranded wires, wherein the plurality of tension members 2 include: U-turn shape tension members 2a bent in a U-turn shape at a depth side of a bored hole 7 and having both ends extending to a tension end; and a tension member 2b having an end part at a depth side of the bore hole 7 formed in a hook shape.SELECTED DRAWING: Figure 1
【課題】長手方向に対して垂直な断面に表れるＰＣ鋼より線の断面の数（本数）を奇数としても、引き抜けを防止し、経済的で、施工上も緊張材の加工や緊張の手間等の負担を軽減する引張型グラウンドアンカーを提供する。【解決手段】ＰＣ鋼より線からなる複数の緊張材２を有し、複数の緊張材２は、削孔７の奥側でＵターン状に折り曲げられ、両端部が緊張端まで延びるＵターン状緊張材２ａと、削孔７の奥側の端部がフック状に形成されたフック状緊張材２ｂと、を含むものとする。【選択図】図１
