The present invention is to provide a concrete pile using a fiber reinforcing material comprising: a plurality of main reinforcing bars formed at certain intervals in the longitudinal direction; fiber reinforcing materials in the form of a lattice net which circularly surround the main reinforcing bars; and concrete in the form of a hollow tube which has a predetermined thickness and includes the main reinforcing bars and the fiber reinforcing material, wherein both ends of the fiber reinforcing material are overlapped with each other so as to form a lap joint and are then fixed to the main reinforcing bars, and the upper end and the lower end of the fiber reinforcing material are overlapped with the lower end and the upper end of the fiber reinforcing materials disposed above and below so as to form lap joints and are then fixed to the main reinforcing bars. The present invention provides a concrete pile comprising main reinforcing bars and fiber reinforcing materials in the form of a lattice net configured to surround the main reinforcing bars, the fiber reinforcing materials having a transverse fiber grid which can replace a conventional hoop, and having a longitudinal fiber grid which can replace a conventional reinforcing bar. Furthermore, due to the integral structure of the fiber reinforcing materials and the concrete, the bond strength increases, and the vertical force, horizontal force, and resistance to bending moment are remarkably improved. Thus, provided is a very useful invention which enables a concrete pile to be used as a substitute for a PHC pile, a steel pipe pile, and a composite pile. |
