PILE HEAD CONNECTING STRUCTURE AND CONNECTING METHOD
To provide a pile head connecting structure and connecting method for directly connecting a steel pipe pile and a column base of a building efficiently by a simple method.SOLUTION: Provided is a connection structure comprising: a steel pipe pile 3 that reaches the hard ground at a position corresponding to a column pedestal base plate 2 of a building; an outer sleeve 4 that is formed in an annular shape having a notch 40 and is welded horizontally near the pile head of the steel pipe pile 3; and a pile head base plate 5 that is placed on the outer sleeve 4, in which a through hole having an inner diameter larger than that of the steel pipe pile 3 is formed, a reverse groove 51 is formed around the through hole, and a plurality of bolt holes 7 penetrated together with the column pedestal base plate 2 are formed, and that is fixed to the column pedestal base plate 2 by bolts. Also provided is a connection method.SELECTED DRAWING: Figure 2
【課題】簡易な方法で効率的に鋼管杭と建築物の柱脚とを直接連結する杭頭の連結構造及び連結方法を提供する。【解決手段】建築物の柱脚ベースプレート２に対応する位置において硬質地盤に到達する鋼管杭３と、切り込み４０を有する環状に形成され、鋼管杭３の杭頭近傍に水平となるように溶接された外スリーブ４と、外スリーブ４上に載置され、鋼管杭３よりも大きい内径を有する貫通孔が形成され、該貫通孔の周辺に逆開先５１が形成され、柱脚ベースプレート２とともに貫通される複数のボルト孔７が形成され、前記柱脚ベースプレート２とボルトによって固定される杭頭ベースプレート５とによって構成される連結構造及び連結方法である。【選択図】図２
