PILE HEAD PROCESSING STRUCTURE, AND PILE HEAD PROCESSING METHOD
To provide a pile head processing structure and a pile head processing method capable of improving bonding strength to concrete, to securely integrate with concrete and having excellent strength, rigidity and soundness of a foundation structure, further the whole structure.SOLUTION: In a pile head processing structure, on an outer peripheral surface of a pile head portion of a foundation pile 10 comprising a steel pipe 10a on an outer periphery of the pile head portion, there are provided a plurality of anchor reinforcements 1 for joining with a foundation structure 11. The plurality of anchor reinforcements 1 are respectively integrated by stacking and welding deformed reinforcements 2. By welding the deformed reinforcement 2 to the steel pipe 10a, the plurality of anchor reinforcements 1 are provided on the outer peripheral surface of the pile head portion of the foundation pile 10 via the deformed reinforcement 2. The deformed reinforcement 2 interposed between the anchor reinforcement 1 and the outer peripheral surface of the pile head portion of the foundation pile 10 is a single deformed reinforcement 2 or is formed by stacking and welding the plurality deformed reinforcements 2.SELECTED DRAWING: Figure 1
【課題】コンクリートとの付着強度を高めて、コンクリートと確実に一体化することができ、基礎構造物、ひいては構造物全体の強度・剛性、および健全性に優れた杭頭処理構造および杭頭処理工法を提供する。【解決手段】杭頭部の外周に鋼管１０ａを備えた基礎杭１０の前記杭頭部外周面に、基礎構造物１１と接合するためのアンカー鉄筋１を複数本設けてなる杭頭処理構造であって、前記複数本のアンカー鉄筋１はそれぞれ、異形鉄筋２を重ねて溶接することで一体化されており、前記異形鉄筋２を前記鋼管１０ａに溶接することで前記複数本のアンカー鉄筋１が前記異形鉄筋２を介して前記基礎杭１０の杭頭部外周面に設けられてなる。前記アンカー鉄筋１と前記基礎杭１０の杭頭部外周面との間に介在される異形鉄筋２は、１本の異形鉄筋２、又は複数本を重ねて溶接してなる異形鉄筋２である。【選択図】図１
