The present invention is to provide a concrete pile using a fiber reinforcing material which includes multiple main reinforcing bars formed at predetermined intervals in the longitudinal direction; a mesh type fiber reinforcing material which circularly surrounds the main reinforcing bars; and a hollow tubular concrete having a predetermined thickness which includes the main reinforcing bars and the fiber reinforcing material, wherein both ends of the fiber reinforcing material are overlapped with one another to form a lap joint to be fixed to the main reinforcing bars, and the upper end of the fiber reinforcing material and the lower end of the fiber reinforcing material are also overlapped with the lower end of the fiber reinforcing material and the upper end of the fiber reinforcing material to form lap joints to be fixed to the main reinforcing bars. Among the fiber reinforcing materials, a transverse fiber grid replaces an existing tie hoop, and a longitudinal fiber grid replaces an existing reinforcing bar. Also, bond strength is improved, and vertical force, horizontal force, and bending moment resistance are remarkably improved due to an integrated structure of the fiber reinforcing material and the concrete, so that the concrete pile using a fiber reinforcing material can be used as a substitute for a PHC pile, a steel pipe pile, and a composite pile. |
