A frictional anchor with a high strength concrete loading structure is provided to cut down construction cost, and to increase tensile strength by preventing breakage of the anchor and minimizing the boring diameter of an anchor hole. Tension is transmitted through a tendon(10) to the ground, and the tendon is surrounded by a slide pipe(30) to restrict the friction between grouting(20) filled in an anchor hole and the tendon. A high strength concrete loading structure is prepared at the end of an anchorage portion of the tendon to transmit tension of the anchor to the grouting, and the exterior of the tendon is exposed. The high strength concrete loading structure is directly and integrally attached to the exterior of the tendon to surround the tendon. The high strength concrete loading structure is made of fiber reinforcing concrete including a fiber reinforcing member made of steel fiber, polypropylene fiber or polyethylene fiber. |
