ANCHOR PILE
To provide an anchor pile that withstands frequent repeated use; that demonstrates sufficient underground resistance force when applied to a compact anchor pile; that can be installed easily with a hammer and the like; that is simple and robust, and can be produced at a low cost.SOLUTION: This invention comprises an outer casing 10, an inner core and a fixing member. The outer casing 10 in a substantially pile shape comprises near the tip at least two openings 15 provided with a sloping surface 16 that slopes inward in the axial direction, and at the rear end at least one pair of notched grooves opposite to one another. The inner core, which is inserted along the axis of the outer casing 10 so that it is slidable, comprises at the tip at least two underground engagement blades 25a and 25b openable and closable, and at the rear end a driving part 21 protruding out of the outer casing 10 through the notched groove. The fixing member can be inserted into the pair of notched grooves opposite to one another. By sliding the inner core in the direction of the tip of the outer casing 10, the underground engagement blades 25a and 25b are made to protrude from the openings 15 while being spread at the maximum spread angle of 90 degrees or smaller along the sloping surface relative to the axis, and further the fixing member is made to be inserted into the outer casing 10.SELECTED DRAWING: Figure 2
【課題】頻繁な反復使用に耐え、小型のアンカー杭に適用しても十分な地中抵抗力を発揮し、ハンマー等で簡単に打設でき、簡易かつ堅牢で、低コストで製造できるアンカー杭を提供する。【解決手段】先端寄りには軸線方向に沿って内部へ傾斜させた傾斜面１６を設けた少なくとも二つの開口部１５を、後端には少なくとも一組の対面する切欠溝を備えた略杭状の外筒１０と、外筒１０の軸線沿いにスライド可能に内装され、先端には少なくとも二つの開閉可能な地中係止翼２５ａ，２５ｂを、後端には切欠溝を通して外筒１０の外に突出する打込部２１を備えた内芯と、前記一組の対面する切欠溝に挿通可能な固定部材とからなり、内芯を外筒１０の先端方向にスライドさせることにより、地中係止翼２５ａ，２５ｂを傾斜面に沿って軸線に対し９０度以下の最大拡開角度にて拡開しつつ開口部１５から突出させ、さらに、固定部材を外筒１０に挿通させる。【選択図】図２
