STEEL PIPE CONNECTION STRUCTURE
PROBLEM TO BE SOLVED: To simplify pretreatment for steel pipe in connecting steel pipes with a mechanical joint.SOLUTION: A steel pipe connection structure 10 has a first member 11 inserted into a steel pipe on the side surface of which an aperture is formed, and a second member 12 inserted into the first member 11. The first member 11 has a projection 111 projecting from an outer peripheral surface 110 and fitted into the aperture, and a pressed surface 112 formed on an inner periphery. An outer diameter of the first member 11 formed by the outer peripheral surface 110 is expandable. The second member 12 has a pressing surface 122 formed on an outer periphery and configured to press the pressed surface 112.SELECTED DRAWING: Figure 1
【課題】機械式の継手を用いて鋼管を連結するにあたり、鋼管に対する事前の加工を簡略化する。【解決手段】鋼管の連結構造１０は、側面に開孔が形成された鋼管の内側に挿入される第１部材１１と、第１部材１１の内側に挿入される第２部材１２とを含む。第１部材１１は、外周面１１０から突出して開孔に嵌合する突起１１１と、内周に形成される被押圧面１１２とを有する。外周面１１０によって形成される第１部材１１の外径は拡縮自在である。第２部材１２は、外周に形成されて被押圧面１１２を押圧する押圧面１２２を有する。【選択図】図１
