INTEGRATED CONSTRUCTION METHOD OF PILE BODY AND STEEL COLUMN AND INTEGRATED STRUCTURE OF PILE BODY AND STEEL COLUMN

To solve the problem in which a foundation construction process is prolonged and cost becomes high.SOLUTION: An integrated construction method of a pile body 1 and a steel column 4 includes steps of: drilling a hole H in the ground G; inserting the pile body 1 into the drilling hole H and burying it in the ground G; constructing an independent foundation 2 installed by a plurality of anchor bolts 3, 3a... with their upper ends protruding, at an upper end of the pile body 1; penetrating the protrusion ends of anchor bolts 3, 3a... into bolt insertion holes 6, 6a... formed at a base plate 5 of the steel column 4, screwing and fastening nuts 7, 7a..., and erecting the steel column 4 on an upper surface of the independent foundation 2. In bar arrangement work in the construction step of the independent foundation 2, by arranging a plurality of hoop reinforcement bars 9, 9a... at an overlapped portion between a plurality of pile head reinforcement bars 8, 8a... provided at the upper end of the pile body 1 and lower end parts of the anchor bolts 3, 3a..., underground beams become unnecessary, the foundation skeleton itself is reduced greatly, the amount of residual soil during the foundation construction is reduced greatly, and also a shorter construction period is achieved. Thus, the total construction cost can be reduced.SELECTED DRAWING: Figure 1 【課題】基礎構築工程が長期化し且つ高額となる。【解決手段】地盤Ｇに孔Ｈを掘削する工程と、この掘削孔Ｈに杭体１を挿設し地盤Ｇに埋設する工程と、複数本のアンカーボルト３、3a...が上端部を突出させて設置された独立基礎２を前記杭体１の上端に構築する工程と、鉄骨柱４のベースプレート５に形成されたボルト挿通孔６、6a...に前記アンカーボルト３、3a...の突出端を貫通させナット７、7a...を螺嵌締結して、独立基礎２の上面に鉄骨柱４を立設する工程とを有する杭体１と鉄骨柱４との一体化工法であって、独立基礎２の構築工程における配筋作業において、杭体１の上端部に設けられた複数本の杭頭補強筋８、8a...と、アンカーボルト３、3a...の下端部との重合部位に複数本のフープ筋９、9a...を配筋することで、地中梁が不要となって、基礎躯体自体を大幅に削減し、且つ基礎構築時の残土量の大幅に削減し、而も工期短縮を図ることで総工事費の削減を可能とする。【選択図】図１
