Zusammenfassung:To provide a technology capable of improving construction efficiency and economic efficiency while ensuring safety in a pile foundation structure including a plurality of piles, a first pile and a second pile having different configurations of pile cap joints.SOLUTION: The degree of fixation of a pile cap 11 of a first pile 10 to a concrete foundation 5 at a pile cap joint 15 is set to be smaller than that of a pile cap 21 of a second pile 20 to the concrete foundation 5 at a pile cap joint 25. The pull-out resistance of the pile cap 11 of the first pile 10 against the concrete foundation 5 at the pile cap joint 15 is set to be larger than that of the pile cap 21 of the second pile 20 against the concrete foundation 5 at the pile cap joint 25.SELECTED DRAWING: Figure 1 【課題】複数の杭として杭頭接合部の構成が互いに異なる第1杭及び第2杭を備えた杭基礎構造において、安全性を確保しながら、施工性及び経済性を向上可能な技術を提供する。【解決手段】杭頭接合部15,25におけるコンクリート基礎5に対する杭頭11,21の固定度については、第1杭10が前記第2杭20よりも小さいものに設定されており、杭頭接合部15,25におけるコンクリート基礎5に対する杭頭11,21の引抜抵抗力については、第1杭10が第2杭20よりも大きいものに設定されている。【選択図】図1
