COLUMN BASE PART STRUCTURE OF STEEL PIPE COLUMN
To provide the column base part structure of a steel pipe column capable of efficiently transmitting axial force of each of adjacent columns to a pile, and allowing easy construction even when a column span is short.SOLUTION: In the column base part structure of a steel pipe column 5, the steel pipe column 5 is jointed to a pile 21. The column structure has one pile 21C, a first steel pile column body 51A and a second steel pipe column body 51B adjacently provided above the one pile 21C, a first column base inclined part 54A and a second column base inclined part 54B jointed to lower ends of the first steel pipe column body 51A and the second steel pipe column body 51B and provided in a sloped state toward the one pile 21C, and a connection steel material part 60 which joints the first steel pipe column body 51A to the second steel pipe column body 51B, and the first column base inclined part 54A to the second column base inclined part 54B. Lower end parts of the first steel pipe column body 51A and the second steel pipe column body 51B, a pile head part 21t of the one pile 21C, the connection steel material part 60, and the first column base inclined part 54A and the second column base inclined part 54B are buried in a foundation concrete part 27.SELECTED DRAWING: Figure 2
【課題】隣接する各柱の軸力を杭に効率的に伝達可能で、かつ柱スパンが短い場合であっても施工が容易な、鋼管柱の柱脚部構造を提供する。【解決手段】鋼管柱５の柱脚部構造は、鋼管柱５と杭２１とが接合される鋼管柱５の柱脚部構造であって、一の杭２１Ｃと、一の杭２１Ｃの上方で互いに隣接して設けられる第１の鋼管柱本体５１Ａ及び第２の鋼管柱本体５１Ｂと、第１の鋼管柱本体５１Ａ及び第２の鋼管柱本体５１Ｂの各々の下端に接合されて、一の杭２１Ｃに向かって傾斜して設けられる第１の柱脚傾斜部５４Ａ及び第２の柱脚傾斜部５４Ｂと、第１の鋼管柱本体５１Ａと第２の鋼管柱本体５１Ｂとを、及び第１の柱脚傾斜部５４Ａと第２の柱脚傾斜部５４Ｂとを接合する連結鋼材部６０と、を備え、第１の鋼管柱本体５１Ａ及び第２の鋼管柱本体５１Ｂの各々の下端部、一の杭２１Ｃの杭頭部２１ｔ、連結鋼材部６０、及び第１の柱脚傾斜部５４Ａ及び第２の柱脚傾斜部５４Ｂが基礎コンクリート部２７に埋設されている。【選択図】図２
