CONNECTION STRUCTURE BETWEEN PILE HEAD OF READY-MADE PILE AND FOUNDATION FOOTING
To efficiently strengthen a pile head portion with a simple structure and effectively connect a ready-made pile to a foundation footing.SOLUTION: A ready-made pile 50 is buried in a pile hole 72, and a pile head portion 51 is exposed from a reference plane 70 to form a footing pile head embedded portion 54. Above the reference plane 70 is a footing body portion 54a. An anchor reinforcing bar is fixed to the pile head portion 51 by protruding upward so as to be located in the footing body portion 54a. An inner vertical main reinforcing bar 1, an outer vertical main reinforcing bar 11, an inner horizontal main reinforcing bar 5, an outer horizontal main reinforcing bar 15, and a shear strengthening reinforcing bar 41 are arranged around the pile head portion 51 in the footing pile head embedded portion 54. Around the pile head portion 51, a plurality of diagonal reinforcing bars 21, a plurality of sets of core reinforcing bars 31, 35, and a plurality of diagonal reinforcing bars 21 are arranged so as to be vertically overlapped. A connection structure 60 is configured by arranging the main reinforcing bars 61, 61 of a foundation beam in the footing body portion 54a.SELECTED DRAWING: Figure 1
【課題】単純な構造で効率よく杭頭部を強化して、既製杭と基礎フーチングとを有効に接続する。【解決手段】杭穴７２内に既製杭５０を埋設して、基準面７０から杭頭部５１を露出させてフーチング杭頭埋め込み部５４を形成する。基準面７０の上方はフーチング本体部５４ａとする。杭頭部５１に、アンカー鉄筋をフーチング本体部５４ａ内に位置するように上方に突出させて固定する。フーチング杭頭埋め込み部５４内で杭頭部５１の周囲に、内縦主鉄筋１、外縦主鉄筋１１、内横主鉄筋５、外横主鉄筋１５、せん断補強鉄筋４１を配置する。杭頭部５１の周囲に、複数段の斜め鉄筋２１、複数段の１組みの中子鉄筋３１、３５、複数段の斜め鉄筋２１を、上下に重なるように配置する。フーチング本体部５４ａ内基礎梁の主鉄筋６１、６１を配置して、連結構造６０を構成する。【選択図】図１
