To provide a bolt hole suspension clamp that can lift a suspended load, such as a steel frame, without causing gripping damage.SOLUTION: There is provided a bolt hole suspension clamp 10 that suspend an H-beam by using the bolt holes that penetrate the flange of the H-beam in the thickness direction, comprising a body bolt 11 that can be inserted through the bolt hole, a sleeve 12 rotatably attached to the base of the body bolt, a nut 13 screwed to the tip of the body bolt, and a suspension ring 14 rotatably attached to the sleeve. This invention can prevent nuts from accidentally falling or being lost, and also allows for smooth nut tightening and lifting operations since it includes: a wire 20, one end of which is rotatably connected to the sleeve via a wire collar 19; a wire 22, one end of which is rotatably connected to the nut via a wire collar 21; and a swivel 23, which is connected between the other ends of the wire to unwind the wire.SELECTED DRAWING: Figure 1

    【課題】掴み傷を与えずに鉄骨などの吊り荷を吊り上げることができる穴吊りクランプを提供する。【解決手段】H形鋼のフランジ部を厚さ方向に貫通するボルト穴を利用してH形鋼を吊り上げる穴吊りクランプ10であり、ボルト穴を挿通可能な本体ボルト11と、本体ボルトの基端部に回転自在に装着されるスリーブ12と、本体ボルトの先端部に螺着可能なナット13と、スリーブに回転自在に装着される吊り環14とを有する。一端がワイヤーカラー19を介してスリーブに回転自在に連結されるワイヤー20と、一端がワイヤーカラー21を介してナットに回転自在に連結されるワイヤー22と、これらワイヤーの他端同士の間に連結されてワイヤーのより戻しを行うスイベル23とを有するので、ナットの不慮の落下や紛失を防止すると共に、ナットの締付作業や吊り上げ作業がスムーズに行える。【選択図】図1
