To provide a suspension bolt capable of reducing burden of positioning work and hardly causing corotation with a nut when the suspension bolt is coupled with the nut.SOLUTION: A coupling suspension bolt is inserted into a suspension groove rail which is narrower in width than an outer diameter of a bolt head and has an opening part extending in a longitudinal direction of the suspension groove rail, and can suspend an instrument. The coupling suspension bolt includes: a plurality of bolts which move in the longitudinal direction of the suspension groove rail in the suspension groove rail and have shaft parts penetrating the opening part; and a coupling member which connects the plurality of bolts to each other and retains intervals in the longitudinal direction of the suspension groove rail of each of the plurality of adjacent bolts.SELECTED DRAWING: Figure 9
【課題】位置決め作業の負担が軽減でき、かつ、ナットとの結合時にナットと供回りしにくい吊りボルトを提供する。【解決手段】本発明の一態様に係る連結吊りボルトは、ボルト頭の外径より狭幅であって吊溝レール長手方向に延びた開口部を有する吊溝レールに挿入され、機器を吊り下げ可能な吊りボルトであって、吊溝レール内を吊溝レール長手方向に移動し、その軸部が開口部を貫通する複数のボルトと、複数のボルト同士を連結し、隣接する各複数のボルトの吊溝レール長手方向の間隔を保持する連結部材と、を備える。【選択図】図9
