To provide a steel sheet pile peeling jig having a mechanism in which a steel sheet pile and a jig can be securely connected by a simple operation and the connection can be simply released when connection is not required, in a situation where peeling laminated steel sheet piles is accompanied with labor and danger.SOLUTION: A jig is constituted of: a clamping body having a cutout area clamping a steel sheet pile end portion from above and below; and a leverage rod rotatably attached to the clamping body. The clamping body is provided with a deflection preventing mechanism portion including an anti-deflection pin fitted in and engaged with a hanging hole at the clamped steel sheet pile end portion. The anti-deflection pin is locked respectively at a fitted state and an unfitted state in the hanging hole of the steel sheet pile end portion.SELECTED DRAWING: Figure 2
【課題】 積層された鋼矢板を引きはがすには労力と危険性が伴う。ところが簡単な動作で鋼矢板と治具とが確実に連結でき、連結の必要がなくなった段階ではその連結を簡単に解除できるという機構を持ち合わせた鋼矢板のはがし治具がこれまでなかった。【解決手段】 鋼矢板端部を上下から挟持する切欠エリアを有する挟持体と、該挟持体に可回動に取設されるテコ桿とにより構成される治具であって、該挟持体には、挟持した鋼矢板端部の吊り孔に嵌って係止されるブレ止めピンを有するブレ防止機構部が設けられており、且つ該ブレ止めピンは、鋼矢板端部の吊り孔に嵌らない状態と嵌る状態のそれぞれでロックされる。【選択図】 図２
