PROBLEM TO BE SOLVED: To provide a steel pipe joining structure in which an inner tube is inserted into the inside of an outer tube and grout is filled between the inner tube and the outer tube, and thereby a tube-axial displacement between the inner tube and the outer tube can be prevented precisely and efficiently, as the steel pipe joining structure where a grout joint part is formed.SOLUTION: A steel pipe joining structure is formed of a grout joint part in which an inner tube is inserted in the inside of an outer tube by only a predetermined length while aligning axial centers and grout is filled between the inner tube and the outer tube. The steel pipe joining structure is characterized in that the outer diameter of the inner tube changes in the pipe axis direction in the grout joint part, and the inner diameter of the outer tube changes in the pipe axis direction.SELECTED DRAWING: Figure 1
【課題】内管が外管の内部に挿入され、内管と外管の間にグラウトが充填されることによって、グラウト接合部が形成されている鋼管接合構造として、内管と外管との管軸方向のずれを的確かつ効率的に防止することができる鋼管接合構造を提供する。【解決手段】内管が外管の内部に軸心を一致させて所定長さだけ挿入され、内管と外管の間にグラウトが充填されることによって、グラウト接合部が形成されている鋼管接合構造であって、グラウト接合部において、内管の外径が管軸方向で変化し、外管の内径が管軸方向で変化していることを特徴とする鋼管接合構造。【選択図】図１
