PURPOSE:To form an economical and strong foundation pile by a method in which the top of a foundation pile and footing are foined with a pin and a load receiving part and a floating-preventing part are provided to the top of the foundation pile. CONSTITUTION:The top of a foundation pile 1 and footing 2 are connected with pins, and a load receiving part 3 to receive vertical loads from the footing 2 and a floating preventing part 4 to prevent the floating of the footing 2 are provided to the top of the foundation pile 1. In this case, the load of a structure is transmitted through a spherical seat 8 from an outer pipe 9 to the foundation pile 1, and a horizontal force is applied to the structure. In case where a drawing force resulting from falling, etc., is acted on the footing, the drawing force is transmitted to the spherical seat 8 and a resistance is offered by the frictional resistance, etc., of the foundation pile 1. In case wherea horizontal force is applied by earthquake, etc., since the outer pipe 9 integrated with the footing 2 and the spherical seat 8 are connected with pins, the action of the horizontal force on the foundation pile 1 can be reduced because of rotation at the part. |
