GROUND ANCHOR LOAD RELEASING COUPLER
To provide a ground anchor load releasing coupler that can remove a load releasing wedge without using a shutter, in which the load releasing wedge and a wedge for pulling are the same in size and are made common, thereby facilitating the management of components and slimming the load releasing coupler overall.SOLUTION: In the load releasing coupler, an upper member 7a and a lower member 7b that have wedge holes 71a and 71b respectively are joined by a joint 7c, a sliding cap 8 is attached on a tip side of the lower member 7b slidably in the vertical direction, a tension steel material 2 is passable in a bottom part of the sliding cap 8, and a bottom part hole 8b with a diameter (φc) smaller than a tip diameter φn of a load releasing wedge 3b is formed. When a jack is loosened after a fixing wedge 3 is removed from an anchor head 4 in a pulling manner, the load releasing wedge 3b contacts the bottom part of the sliding cap 8 and is then lifted, and therefore becomes removed from the wedge hole 71b automatically.SELECTED DRAWING: Figure 7
【課題】シャッターを使用することなく除荷用クサビを取り外し可能としたグラウンドアンカーの除荷用カプラーであって、除荷用クサビと引張用クサビの大きさを同じ大きさとし、共通化して部品管理を容易にすると共に除荷用カプラー全体をスリム化する。【解決手段】クサビ穴７１ａ、７１ｂをそれぞれ有する上部材７ａと下部材７ｂがジョイント７ｃで接合されており、下部材７ｂの先端側にスライドキャップ８が上下にスライド可能に取り付けてあり、このスライドキャップ８の底部に緊張鋼材２が通過可能であって、かつ、除荷用クサビ３ｂの先端直径φｎより小径（φｃ）の底部穴８ｂが形成してある除荷用カプラーであり、定着クサビ３をアンカーヘッド４より引抜除去した後、ジャッキを緩めると除荷用クサビ３ｂはスライドキャップ８の底部に当接して押し上げられるのでクサビ穴７１ｂから自動的に外れる。【選択図】図７
