HOLDING MECHANISM OF STEEL PIPE POLE
To extend a steel pipe pole in an upright posture via a screw joint and improve workability in assembling it into an underground hole.SOLUTION: When a steel pipe pole in an upright posture having a screw joint at an upper end and a lower end is extended utilizing an underground hole, a holding mechanism of the steel pipe pole holds the steel pipe pole situated at a lower side in a state of being suspended in the underground hole, a taper surface is formed on an outer peripheral surface of the screw joint provided at the lower end of the steel pipe pole and the holding mechanism comprises an openable type support frame having an opening into which the steel pipe pole can be inserted and a plurality of support pieces projecting toward the steel pipe pole inserted into the opening and having a placement surface on which the taper surface of the screw joint is placed.SELECTED DRAWING: Figure 4
【課題】起立姿勢の鋼管柱をネジ継手を介して継ぎ足しつつ、地中孔に建込む際の作業性を向上する。【解決手段】上端部及び下端部にネジ継手を備える起立姿勢の鋼管柱を、地中孔を利用して継ぎ足す際、下側に位置する前記鋼管柱を前記地中孔内に垂下させた状態で保持する鋼管柱の保持機構であって、前記鋼管柱の下端部に設けた前記ネジ継手の外周面に、テーパー面が形成されており、前記保持機構は、前記鋼管柱を挿通可能な開口が設けられた開閉式支持架台と、前記開口に挿通された前記鋼管柱に向けて突出し、前記ネジ継手の前記テーパー面が載置される載置面を有する複数の支持ピースと、を備える。【選択図】図４
