COLUMN BASE STRUCTURE
To provide a column base structure capable of increasing a fastening degree of an anchor bolt while securing bearing ability with a relatively small skeleton cross section.SOLUTION: A column base structure 1, in which a pile 10 extending along a prescribed axis A is joined to a base portion 21 of a steel column 20, comprises: a plurality of anchor bolts 30 extending in parallel with the axis A and disposed in the vicinity of the pile 10; a steel pipe 40 extending in parallel with the axis A and disposed so as to surround a pile head portion 11 of the pile 10 and the anchor bolt 30 from outside; and a base plate 50 which is joined to an opening 41 formed vertically above the steel pipe 40 and through and to which an upper part of the anchor bolt 30 is inserted and fixed. A filler C is filled into a space in the steel pipe 40, and thus the pile head portion 11 and the anchor bolt 30 are restricted from an outside. The base portion 21 of the steel column 20 is joined to an upper part of a base plate 60.SELECTED DRAWING: Figure 1
【課題】比較的小さい躯体断面で耐力を確保しつつ、アンカーボルトの定着度を増大させることができる柱脚構造を提供する。【解決手段】所定の軸Ａに沿って延在する杭１０が鉄骨柱２０の脚部２１に接合されてなる柱脚構造１であって、軸Ａに対して平行に延在するとともに杭１０の近傍に配置される複数のアンカーボルト３０と、軸Ａに対して平行に延在するとともに杭１０の杭頭部１１及びアンカーボルト３０を外側から包囲するように配置される鋼管４０と、鋼管４０の鉛直方向上方に形成された開口４１に接合されるとともにアンカーボルト３０の上部が挿通されて固定されるベースプレート５０と、を備える。鋼管４０内の空間に充填剤Ｃを充填することにより杭頭部１１及びアンカーボルト３０を外側から拘束する。ベースプレート６０の上部に鉄骨柱２０の脚部２１を接合する。【選択図】図１
