A head reinforcing structure of a steel pipe pile is provided to improve the construction efficiency, to improve the intensity, and to have economical efficiency by minimizing the weight of a coupler. A head reinforcing structure of a steel pipe pile is composed of a pipe(11) in which a stud bolt(13) is weld/fixed to the inner or outer circumference and which is formed at the constant length and diameter, a coupler(21) in which a plurality of bolt hole(25) is formed and a screw fastening and seating portion(37) directly supported to the upper part of the pipe is formed, a nut(31) connected to the stud bolt fixed/welded to the outer circumference of the pipe by passing through the bolt hole of the coupler, and a pile head reinforcing bar(43) in which the screw thread is formed in the bottom part. |
