PURPOSE : An earth-anchor structure for support of a structure or ground reinforcement construction is provided to facilitate the construction by allowing an expansion part to be expanded in a hole more conveniently, and prevent malfunction thereof. CONSTITUTION : An earth-anchor structure for support of a structure or ground reinforcement construction, assists fixation of a tension material onto the ground, being inserted in a hole and expanded to inner circumference of the hole. The earth-anchor structure comprises an anchor cap(16) mounted to a leading end of an anchor body(14) connected with a steel wire(10) by a taper cone(12), and an expanded anchor(20) protruded in radial directions by resilient force of a spring(18) from a position between the anchor cap and the anchor body. The anchor cap thus functions as a support body that supports the expanded anchor against tension of the steel wire. A locking device(22) is inserted in the anchor body within the expanded anchor to support the inserted state thereof and allow protrusion in radial directions thereof. © KIPO 2006
