PARALLEL THREADED JOINT FOR STRUCTURAL STEEL PIPE
PROBLEM TO BE SOLVED: To obtain a parallel threaded joint for a structural steel pipe with less rotation angle to improve working efficiency and having no directionality in strength and rigidity.SOLUTION: A parallel threaded joint 1 for a structural steel pipe according to the present invention is used in joining steel pipes constituting a structural body. The relationship between the number of threads M to be engaged and the thread number N is set to M/N≤0.5 and M≤4. A range in which the number of threads to be engaged is different from M is set to a predetermined ratio or less with respect to the joint circumferential direction length.SELECTED DRAWING: Figure 1
【課題】回転角度を少なくして作業効率を向上すると共に強度や剛性に方向性のない構造体鋼管用平行ねじ継手を得る。【解決手段】本発明に係る構造体鋼管用平行ねじ継手１は、構造体を構成する鋼管の接合に用いられる構造体鋼管用平行ねじ継手１であって、嵌合するねじ山数Ｍとねじ条数Ｎとの関係がＭ／Ｎ≦0.5に設定されると共に、Ｍ≦４であり、嵌合するねじ山数がＭと異なる範囲が、継手周方向長さに対して所定割合以下に設定されていることを特徴とするものである。【選択図】 図１
