CONCRETE PILE WITH OUTER-SHELL STEEL PIPE
PROBLEM TO BE SOLVED: To provide a concrete pile with outer-shell steel pipe of which the flexure capacity and toughness are improved further than the prior arts.SOLUTION: The concrete pile with outer-shell steel pipe comprises: an outer-shell steel pipe; and a hollow and cylindrical pile body which is disposed within the outer-shell steel pipe while being deposited to an inner circumferential surface of the outer-shell steel pipe and at least partially contains concrete. When D denotes an outer diameter of the outer-shell steel pip, tc denotes thickness of the pile body, ts denotes thickness of the outer-shell steel pipe, T(=tc+ts) denotes a total of the thickness of the pile body and of the outer-shell steel pipe, and T/D denotes a ratio of the thickness and the diameter, the concrete pile with outer-shell steel pipe satisfies a relationship indicated by an inequality of 0.24≤T/D<0.5.SELECTED DRAWING: Figure 1
【課題】曲げ耐力及び靭性が従来よりも改善された外殻鋼管付きコンクリート杭を提供する。【解決手段】外殻鋼管付きコンクリート杭は、外殻鋼管と、前記外殻鋼管の内周面に付着した状態で前記外殻鋼管内に配置され、コンクリートを少なくとも一部に含む中空で円筒形状の杭体と、を備え、外殻鋼管の外径をＤとし、杭体の厚さをｔｃとし、外殻鋼管の厚さをｔｓとし、杭体及び外殻鋼管の厚さの合計をＴ（＝ｔｃ＋ｔｓ）とし、径厚比をＴ／Ｄとしたとき、次式：０．２４≦Ｔ／Ｄ＜０．５で示される関係を満たしている。【選択図】 図１
