Summary:To provide a reinforced concrete pile structure capable of securing necessary proof strength and having excellent workability with a reduced number of vertical main reinforcements, even when large bending moment is applied to a pile head.SOLUTION: A reinforced concrete pile 1 has a reinforcement cage 4 cylindrically formed by combining multiple vertical main reinforcements 22 and annual and lateral hoop reinforcements 3 and installed inside a concrete column. Partially high-strength bars 2 with at least a part in the longitudinal direction formed in high strength, are included as the multiple vertical main reinforcements 22.SELECTED DRAWING: Figure 1 【課題】 杭頭に大きな曲げモーメントが作用した場合でも、縦主筋の本数を抑えた構成で、必要とする耐力を確保することが可能であり、かつ、施工性に優れた鉄筋コンクリート杭構造を提供する。【解決手段】 複数の縦主筋２２と環状の横フープ筋３を組み合わせて筒状に形成した鉄筋籠４が、コンクリート柱に内設された鉄筋コンクリート杭１において、前記縦主筋２２として、長さ方向の少なくとも一部が高強度に形成された部分高強度鉄筋２を含むことを特徴とする。【選択図】図１
