PROBLEM TO BE SOLVED: To provide an anchoring device which has no limitation of a fitting position on an anchoring rod and enables a quick and safe operation without skill.SOLUTION: An anchoring device 1 comprises a wedge unit 2, a yoke metal fitting 5, and a connection rope 7. The wedge unit 2 includes gripping metal fittings 3, 4 which are hinge-connected so as to be freely opened and closed. The yoke metal fitting 5 includes a wedge receiving space in which the wedge unit 2 is wedge-fitted. The connection rope 7 engagingly locked by a support arm 8 of the yoke metal fitting 5 is connected with one traction wire W of a wire grip. The gripping metal fittings 3, 4 are approximately conical shapes and includes facing planes and sliding curve surfaces. The gripping metal fittings 3, 4 includes a temporary tightening component 9 which temporarily grips an anchoring rod R. An opening included in the wedge receiving space is, when the yoke metal fitting 5 is drawn to an extended line side, wedge-fitted with the wedge unit 2 so as to firmly grip the anchoring rod R between the gripping metal fittings 3, 4.SELECTED DRAWING: Figure 4
【課題】引き留めロッド上への装着位置に制約がなく、熟練を要することなく、作業を迅速かつ安全に進めることができる引き留め装置を提供する。【解決手段】引き留め装置1は、クサビユニット2、ヨーク金具5、接続索7を具備する。クサビユニット2は、開閉自在にヒンジ結合された把持金具3,4を有する。ヨーク金具5は、クサビユニット2をクサビ嵌合させるクサビ受け空間を有する。ヨーク金具5の支持アーム8に係止された接続索7は、張線器の一方の牽引ワイヤWに接続される。把持金具3,4は、概略半円錐形状で、対向平面と滑り曲面を有する。把持金具3,4は、引き留めロッドRを仮に把持する仮締め部材9を具備する。クサビ受け空間は、開口を具備し、ヨーク金具5が延線側へ引かれると、クサビユニット2とクサビ嵌合し、把持金具3,4間に引き留めロッドRを強固に把持する。【選択図】図4
