STEEL PIPE COUPLING JIG AND STEEL PIPE COUPLING METHOD
PROBLEM TO BE SOLVED: To facilitate work for coupling steel pipes together.SOLUTION: A steel pipe coupling jig 1 comprises a main shaft part 2 which assumes a cylindrical shape with an outside diameter approximately equal in length to an inside diameter of a first pin hole 16 and which is inserted into the first pin hole 16 during execution of work, and a cam shaft part 3 which is a circular cylinder having smaller-diameter curvature than the main shaft part 2 and extended in a direction of a central axis A3 of the main shaft part 2 and which is fixed to an end surface of the main shaft part 2 so as to be inscribed in an outer peripheral edge of the main shaft part 2.SELECTED DRAWING: Figure 3
【課題】鋼管同士の連結作業を容易にする。【解決手段】鋼管連結治具１は、第１ピン孔１６の内径と略同じ長さの外径を有する円柱状をなし、施工時に第１ピン孔１６に挿入される主軸部２と、主軸部２よりも小径の曲率であると共に主軸部２の中心軸線Ａ３の方向に延びる円柱であって、主軸部２の外周縁に内接するように主軸部２の端面に固定されたカム軸部３と、を備える。【選択図】図３
