To provide an internal hanging clamp suitable for hanging foot protection blocks.SOLUTION: An internal hanging clamp 10 has a main body 11 having a pair of side edges 13 that can abut against an upper inclined surface 2a of a hole 2 of a foot protection block 1, an opening arm 22 that can be raised and lowered along a center line 12 in the width direction of the main body, an opening lever 18 that moves the opening arm between an upper position (Fig. 1) and a lower position (Fig. 2), and a pair of receiving metals 31 that, when the opening arm is in the upper position, are in a closed state that fits within a width dimension that can pass through a central narrow portion 2c of the hole of the foot protection block, and when the opening arm is in the lower position, are in an open state that can abut against a lower inclined surface 2b of the hole of the foot protection block. The receiving metals are locked in the open state (Fig. 1) or the liftable state (Fig. 2) by aligning an insertion/removal pin insertion hole 29 of the main body with the first or second insertion/removal pin locking hole 20, 21 of the opening lever and inserting the insertion/removal pin 28 through them.SELECTED DRAWING: Figure 2
【課題】根固ブロックの吊り上げに適した内吊りクランプを提供する。【解決手段】根固ブロック1の穴2の上方傾斜面2aに当接可能な一対の側縁部13を有する本体11と、本体の幅方向中心線12に沿って昇降可能な開放アーム22と、開放アームを上方位置(図1)と下方位置(図2)との間で移動させる開放レバー18と、開放アームが上方位置にあるときは根固ブロックの穴の中央幅狭部2cを通過可能な幅寸法に収まる閉じ状態となり、開放アームが下方位置にあるときは根固ブロックの穴の下方傾斜面2bに当接可能な開き状態とまる一対の受け金31と、を有する内吊りクランプ10。本体の抜き差しピン挿通穴29と開放レバーの第一または第二の抜き差しピン係止穴20,21とを整列させてこれらに抜き差しピン28を挿通させることにより、受け金を開放状態(図1)または吊上可能状態(図2)にロックする。【選択図】図2
