To provide a pile head semi-rigid joint structure which semi-rigid joins a joint part between a steel pipe pile and a pile cap (or foundation slab) with a simple structure.SOLUTION: A pile head semi-rigid joint structure 1 is composed of a steel pipe pile 3 which is penetrated into a ground 2 and has a predetermined diameter D, a pile head pipe 5 which has an upper part embedded in a pile cap 4 mounted on the ground 2 with a predetermined range and has a diameter d smaller than the diameter D of the steel pipe pile 3, a first straight pipe part 7 which is composed of a different diameter pipe 6 connecting the steel pipe pile 3 and the pile head pipe 5, in which the different diameter pipe 6 has the same diameter as the steel pipe pile 3, a second straight pipe part 8 having the same diameter as the pile head pipe 5, and a transfer part 11 which is arranged between the first straight pipe part 7 and the second straight pipe part 8, and is composed of a convex surface diameter reduced part 9 which is reduced in its diameter in a convex curve shape from the first straight pipe part 7 and a concave surface diameter reduced part 10 which is reduced in its diameter in a concave curve shape toward the second straight pipe part 8 from the convex surface diameter reduced part 9.SELECTED DRAWING: Figure 1
【課題】鋼管杭とパイルキャップ（あるいは基礎スラブ）の接合部を簡易な構造で半剛接合とした杭頭半剛接合構造を提供する。【解決手段】杭頭半剛接合構造１は、地盤２に貫入される所定の径Ｄを有する鋼管杭３と、地盤２上に載置されるパイルキャップ４内に上部が所定の範囲で埋設され、前記鋼管杭３の径Ｄよりも小さい径ｄを有する杭頭管５と、鋼管杭３と杭頭管５との間を連結する異径管６とによって構成され、前記異径管６は、前記鋼管杭３と同一の径を有する第１の直管部７と、前記杭頭管５と同一の径を有する第２の直管部８と、前記第１の直管部７と前記第２の直管部８の間に配され、前記第１の直管部７から凸曲面状に縮径する凸曲面縮径部９および該凸曲面縮径部９から前記第２の直管部８に向けて凹曲面状に縮径する凹面縮径部１０からなる移行部１１とによって構成される。【選択図】図１
