To provide an underground anchor in which a blade has high strength, driving resistance into a ground is small, and a tip portion is hardly damaged or deformed.SOLUTION: A metal underground anchor 1 comprises a central cylinder portion 2, a pair of blade portions 3, a shaft bearing portion 4 and a vertical blade portion 5. The central cylinder portion 2 includes a connection pipe portion 2c bearing a driving rod and opening at a base end side, and extends toward a sharp and closed tip while gradually narrowing. The blade portion 3 comprises a flat plane portion 3c, a bent plane portion 3d, and a flange portion 3e. The shaft bearing portion 4 is erected upward from an upper side face of the central cylinder portion 2. The vertical blade portion 5 has a substantially triangle plate shape having a slope face 5a. The central cylinder portion 2 includes: an inclined end surface 2e lowering toward the rear at the base end side; and the connection pipe portion 2c including a bottom portion 2d bearing the driving rod to be driven underground.SELECTED DRAWING: Figure 1
【課題】翼の強度が高く、地中への打ち込み抵抗が小く、先端部が損傷、変形しにくい地中アンカーを提供する。【解決手段】地中アンカー1は、金属製で、中心筒部2、一対の翼部3、軸受部4、垂直翼部5を具備する。中心筒部2は基端側に打ち込み棒を受ける接続管部2cが開放し、尖って閉塞した先端へ向かって徐々に収縮して伸びる。翼部3は、水平面部3c、折曲平面部3d、フラップ部3eを具備する。軸受部4は、中心筒部2の上側面から上方へ起立する。垂直翼部5は、斜面5aを有する概略三角形板状である。中心筒部2は、基端側に、後方に向かって下方へ下がる傾斜端面2eを有すると共に、地中に打ち込むための打ち込み棒を受ける底部2dを持つ接続管部2cを有する。【選択図】図1
