PROBLEM TO BE SOLVED: To provide a coupled structure of a foundation pile, which prevents settlement of a foundation and a structure on the foundation, cause by an decrease in the strength of the whole pile after construction, by making a breakage such as a crack hardly caused in a coupled portion by a coupling member for coupling a pile component constituting the foundation pile.SOLUTION: The foundation pile (S) is the coupled structure in which a required number of pile components (1, 1a and 1b) are longitudinally coupled together; fitting protrusions (10, 11, 12 and 13), which are protruded in an axial direction, are formed at the coupling-side ends of the pile components on one side and the other side, which are coupled to each other, respectively; and both the pile components (1 and 1a) and (1a and 1b) are coupled together by externally fitting the cylindrical coupling member (2) so as to connect both the fitting protrusions (10 and 11) and (12 and 13). |
