MULTISTAGE EXPANSION TYPE EARTH ANCHOR ASSEMBLY
PROBLEM TO BE SOLVED: To provide a multistage expansion type earth anchor assembly, usable for a base rock and the weak ground, and further strongly anchoring-fixing a blade member fixed in close contact to an inner wall of a bore hole, in-to the inner wall of the bore hole by translational motion and rotary motion.SOLUTION: A multistage expansion type earth anchor assembly includes a fixed member 10 inserted into the inside of a bore hole formed on the ground surface, a moving member 20 slidingly installed in the vertical direction to the fixed member and moving in the vertical direction by a tension wire connected to an external part of the bore hole, a large number of blade members 30 for rotatably joining a lower part to the fixed member by a hinge and a rotary pin 40 for rotatably joining a lower part of the blade members to the fixed member by a hinge, and the blade members are expanded by rotating an upper part around the lower part after moving the upper part and the lower part together in the side direction to the fixed member by a rise in the moving member.
【課題】岩盤用及び軟弱地盤用に使用することができ、穿孔ホールの内壁に密着固定される羽根部材が並進運動と回転運動とによって穿孔ホールの内壁に、より強く定着固定される多段拡張型アースアンカーアセンブリを提供する。【解決手段】地面に形成された穿孔ホールの内部に挿入される固定部材１０と、前記固定部材の下部に配置され、前記固定部材に対して上下方向にスラィディング可能に装着され、前記穿孔ホールの外部に連結された引張線によって上下方向に移動する移動部材２０と、下部が前記固定部材に回転可能にヒンジ結合された多数個の羽根部材３０と、前記羽根部材の下部を前記固定部材に回転可能にヒンジ結合する回転ピン４０と、を含んで成り、前記羽根部材は、前記移動部材の上昇により前記固定部材に対して上部と下部とが側方向に一緒に移動した後、上部が下部を中心に回転して展開される。【選択図】図３
