Therefore, since the stress generated in the metal fitting is supported by the bending tensile force of the steel material, the jig structure becomes uneconomical. An object of the present invention is to solve the above problems and provide a joining method and joining device for a steel column and a steel pipe pile capable of efficiently performing a joining operation.

Is larger than the diameter of the foundation steel pipe pile, and the other side forms a conical curved surface.
The steel frame column 3 and the flat part of the joining jig 1 are welded in advance, and then the conical curved surface part is welded to the upper end of the steel pipe pile 4 so that the steel frame column 3 is at a predetermined angle and position. And
In the present invention, the conical joining jig 1 is integrated by welding the flat portion thereof to the pillar and the curved portion thereof to the steel pipe pile 4, and the joining jig has such a shape. Makes its production easier. Next, this structure can effectively transmit the stress from the steel column 3 to the steel pipe pile 4 by effectively combining the mechanical properties of the concrete 2 and the metal object forming the joining jig 1. Because
The cross section of the joining jig 1 is also highly economical. That is, first, the compressive stress from the steel frame column 3 is transmitted to the concrete 2 which is strong against the compressive force, and this stress is transmitted as a pure tensile force to the metallic object which is strong against the tensile force by making the shape of the metallic object into a conical shape. Is transmitted to the steel pipe pile 4 and has a structure in which the characteristics of the materials are effectively combined in the process of stress transmission. Further, the conical jig 1 for joining is preliminarily attached to the steel column 3
