To provide a ground anchor for which new tendons can be arranged and constructed by replacement of tendons that have been deteriorated or may be deteriorated.SOLUTION: For a ground anchor (10) of this invention, a lower mansion tapered section (3B) for which a diameter on the underground side is expanded is formed in a hollow section (3A) of a lower mansion (3). A hollow section (1A) is formed radially inside a tendon (1). A holding section axis (2) is disposed in the hollow section (1A). A holding section (2A) provided with a holding section side tapered section whose diameter is reduced as it goes toward the ground side is formed at the underground tip of the holding section axis (2). When the holding section axis (2) is pulled toward the ground side, the tapered section of the holding section (2A) engages with the hollow section (1A) of the tendon (1), a diameter of an underground end (1B) of the tendon (1) is expanded, and the diameter-expanded underground end (1B) engages with the tapered section (3B) of the lower mansion (3).SELECTED DRAWING: Figure 1
【課題】劣化した或いは劣化の恐れがある引張材に代えて，新しい引張材を配置，施工することが出来るグラウンドアンカーの提供。【解決手段】本発明のグラウンドアンカー（１０）は，下部マンション（３）の中空部（３Ａ）に地中側が拡径する下部マンションテーパー部（３Ｂ）が形成されており，引張材（１）の半径方向内側には中空部（１Ａ）が形成され，当該中空部（１Ａ）には把持部用軸（２）が配置されており，把持部用軸（２）の地中側先端には地上側に向かって縮径する把持部側テーパー部を設けた把持部（２Ａ）が形成されており，（把持部用軸２が地上側に引っ張られると）把持部（２Ａ）のテーパー部が引張材（１）の中空部（１Ａ）に係合して引張材（１）の地中側端部（１Ｂ）が拡径しており，当該拡径した地中側端部（１Ｂ）が下部マンション（３）のテーパー部（３Ｂ）と係合している。【選択図】図１
