PURPOSE:To form a strong foundation pile by a method in which the top of foundation pile and footing are connected with each other in such a way as to enable the footing to move in the horizontal direction in relation to the top of the foundation pile and a load receiving part and a floating prevention part is provided to the top of the foundation pile to prevent the generation of bending moment and shearing force by earthquake, etc. CONSTITUTION:The top of a foundation pile 1 and a footing 2 are connected in such a way as to enable the footing 2 to move in the hotizontal direction in relation to the top of the foundation pile 1, and a load receiving part 3 to receive loads from the footing 2 and a floating prevention part 4 to prevent the floating of the footing 2 are provided to the top of the foundation pile 1. By this, in case where a horizontal force acts on a structure and a drawing force resulting from falling, etc., acts on the footing 2, they are transmitted to the foundation pile 1 at the lower face of a collar part 8 and a resistance is offered by frictional resistance, etc., of the foundation pile 1. In case where a horizontal force acts by earthquake etc., and a difference in horizontal displacement between the footing 2 and the foundation pile 1 occurs, the displacement is absorbed by the buffering action of the buffer material 15. |
