PROBLEM TO BE SOLVED: To provide an efficient and economical bearing pile resistant to bending moment by inexpensively connecting pieces of shape steel different in size. SOLUTION: In this structure of the bearing pile, a pile body is inserted into a drilled hole 5 which is drilled in ground, and a hardening material such as mortar 6 and concrete is injected into the periphery of the pile body and hardened. The pile body 1 is constituted by connecting two or more types of pieces 2 and 3 of shape steel, different in the breadthwise sizes of a web W and a flange. A connecting plate 4 is interposed between the pieces 2 and 3 of shape steel, different in size, and end surfaces of the pieces of shape steel are connected to top and under surfaces of the connecting plate by butt welding, respectively. The efficient and economical bearing pile A is provided by using the thick high strength shape steel only for a portion undergoing the action of the great bending moment. Inexpensive construction can be performed by making the number of components smaller than in the case of the use of a splice plate etc. , and the load can be properly transferred in a vertical direction.
