PROBLEM TO BE SOLVED: To provide a joint structure between a large diameter tube and a small diameter tube each having a diameter different from each other for allowing fluid to pass therethrough while ensuring required flexural capacity, axial strength and shear capacity in the joint part with a small working amount in the joint part at a low cost.SOLUTION: The joint structure is constituted of, including: a small diameter steel pipe 1; and a large diameter steel pipe 2; and a flat joint steel plate 3. After inserting the end part of the small diameter steel pipe 1 as the pile main body part into the end part of the large diameter steel pipe 2 of an expanded head part H in a tube in a tube axial direction, the flat joint steel plate 3 having a generally sector-shape is placed and welded between the large diameter steel pipe 2 of the expanded head part H and the small diameter steel pipe 1 as the pile main body part being inclined in the tube axial direction.SELECTED DRAWING: Figure 1

【課題】径の異なる大径管と小径管との接合構造として、接合部に必要の曲げ耐力、軸耐力、せん断耐力を確保しつつ、接合部の加工量が少なく経済性の高い、管内を流動物が通過できる異径管の接合構造を提供する。【解決手段】拡頭部Ｈの大径鋼管２端部内に杭本体部の小径鋼管１端部を管軸方向に挿通させ、拡頭部Ｈの大径鋼管２と杭本体部の小径鋼管１との間に平らな略扇形の継手鋼板３を管軸方向に対し傾斜して溶接する。【選択図】図１
