| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a knotted pile for improving long-term pile material allowable bearing power, while securing shear strength of a node part.SOLUTION: A knotted pile comprises a cylindrical body part and at least one node part of projecting from an outer peripheral surface of the body part. The body part and the node part include concrete, and assuming the occupied area of the node part in the outer peripheral surface of the body part as the bottom area Ar and the area of the node part projected in the axial direction of the body part to an orthogonal surface to the body part as the projection area An, the ratio An/Ar of the projection area An to the bottom area Ar is 0.069-0.320.SELECTED DRAWING: Figure 8
【課題】節部の剪断耐力が確保されながら、長期杭材許容支持力が改良された節杭を提供する。【解決手段】節杭は、円筒形状の本体部と、本体部の外周面から突出する少なくとも１つの節部とを備える。本体部及び節部はコンクリートを含み、本体部の外周面における節部の占有面積を根元面積Ａｒとし、本体部と直交する面に対し本体部の軸線方向にて投影された節部の面積を投影面積Ａｎとしたとき、根元面積Ａｒに対する投影面積Ａｎの比Ａｎ／Ａｒは０．０６９以上０．３２０以下である。【選択図】 図８ |
