To provide a joint structure of a pile and a column and a method for constructing the same, which eliminate the need for footings and foundation beams, reduce the amount of excavated soil and the amount of steel frames used, simplify the structure, and reduce costs, in which bending force generated in the joint can be reduced by making the joint form a semi-rigid joint, and rationality and economic efficiency can be improved.SOLUTION: A joint structure of a pile 1 has a hollow cross section and a column 2 is provided, in which at a lower end of the column 2, a base plate 21 and a shear key 23 extending downward from the base plate 21 and inserted into an upper end of the pile 1 and having an outer dimension smaller than that of the column 2 are provided. A space from the upper end of the pile 1 to the lower surface of the base plate 21 is filled with concrete 4 so as to cover the periphery of the shear key 23.SELECTED DRAWING: Figure 2 【課題】フーチングや基礎梁を不要として、掘削土量及び使用鉄骨量を削減して、構造の簡素化及びコストダウンを図るとともに、接合形態を半剛接合とすることで接合部に生じる曲げ力を低減して、合理性及び経済性を高めることができる、杭と柱との接合構造及びその施工方法を提供する。【解決手段】中空断面を有する杭１と柱２との接合構造であって、柱２の下端部には、ベースプレート２１と、ベースプレート２１から下方に延出し杭１の上端部内に挿入される、柱２よりも小さい外寸を有するシアキー２３とが設けられ、杭１の上端部からベースプレート２１の下面までの空間に、シアキー２３の周囲を覆うようにコンクリート４が充填される、杭１と柱２との接合構造。【選択図】図２
