PROBLEM TO BE SOLVED: To provide a clamp capable of safely and efficiently performing a pulling-up/inverting operation for a sheet pile.SOLUTION: A clamp 20 for a sheet pile includes: a clamp body 23 having a pair of body pins 21a and 21 and a work insertion port 22; a cam 24 retractable into/from the work insertion port; a receiving part 26 facing the cam across the work insertion port; a hanging ring 28 having a hanging ring pin 29 moving along a hanging ring pin groove 27 formed between the pair of body pins; and a link 31 transmitting the movement of the hanging ring pin to the cam. Since the hanging ring is abutted on one of the body pins when lifting the hanging ring in a state of inserting a joint part 2 of the upward or downward sheet pile 1 into the work insertion port, the hanging ring pin moves in a groove opening direction in the hanging ring pin groove with the abutting point as a fulcrum, and the lateral surface of the sheet pile is surely gripped with the receiving part by projecting the cam to the work insertion port via the link.SELECTED DRAWING: Figure 4

    【課題】シートパイルの引き起こし・反転作業を安全且つ効率良く行うことができるクランプを提供する。【解決手段】このシートパイル用クランプ20は、一対の本体ピン21a,21とワーク挿入口22を有するクランプ本体23と、ワーク挿入口に出没可能なカム24と、ワーク挿入口を挟んでカムと対向する受け部26と、一対の本体ピンの間に形成された吊環ピン溝27に沿って移動する吊環ピン29を有する吊環28と、吊環ピンの移動をカムに伝えるリンク31とを備え、上向きまたは下向きのシートパイル1の継手部2をワーク挿入口に挿入した状態で吊環を吊り上げたときに、吊環がいずれか一方の本体ピンに当接するように構成されているので、該当接点を支点として吊環ピンが吊環ピン溝内において溝開口方向に移動し、リンクを介してカムをワーク挿入口に突出させて、シートパイルの側面部を受け部との間で確実に把持する。【選択図】図4
