RESTRAINING DEVICE OF GROUND ANCHOR HEAD FIXING PORTION
To increase a bearing capacity of a tensile material against impact loads when the tensile material is used as a resistance material against impact forces on preventing a head fixing portion from popping out of an object to be fastened to which a head fastening portion is fastened in a case an underground section of a ground anchor is broken.SOLUTION: A ground anchor 11 comprises: a tensioning member 9 embedded in the ground under tension; and a cap 10 covering a head fastening portion 92 connected to a head of the tensioning member 9 at a ground surface side and fastened to a fastening plate 13 arranged on a surface of an object 12 to be fixed on the ground. A restraining device 1 is constituted of: a pressing plate 2 directly or indirectly overlapping a ground side end face of the cap 10; and a tensile material 3 arranged to pass through a surface of the pressing plate 2. The tensile material 3 is fixed to the object 12 to be fixed at a position passing through the center of a plane of the surface of the pressing plate 2 or the vicinity thereof and facing the object 12 to be fastened with the pressing plate 2 interposed therebetween.SELECTED DRAWING: Figure 1
【課題】地盤アンカーの地中区間が破断した場合に備え、頭部定着部が定着されている被定着体からの頭部定着部の飛び出しを防止する上で、衝撃力に対する抵抗材として張力材を使用する場合に、衝撃的な荷重に対する張力材の負担能力を高める。【解決手段】緊張力を付与された状態で地中に埋設される緊張材９と、緊張材９の地表面側の頭部に接続され、地上の被定着体１２の表面に配置された定着板１３に定着される頭部定着部９２を被覆するキャップ１０とを備えた地盤アンカー１１において、キャップ１０の地上側の端面に直接、もしくは間接的に重なる押さえプレート２と、押さえプレート２の表面を通って配置される張力材３から拘束装置１を構成し、張力材３を押さえプレート２の表面の平面上の中心、もしくはその付近を通り、押さえプレート２を挟んで対向する位置で被定着体１２に定着させる。【選択図】図１
