<p>The present invention relates to a fixing device for an earth anchor having an improved coupling structure for more stable construction, and an improved internal structure for easier removing and re-tensioning of steel wires. In the fixing device for the earth anchor, two of the fixing devices being coupled side by side at the lower side of a steel wire fixing device to which a plurality of steel wires are fixed, coupling grooves are formed on the outer circumferential surface of the fixing device, and a support member is coupled by means of a bolt which penetrates between the two coupling grooves, wherein the support member comprises a pair of brackets, which are provided with coupling apertures through which the bolt penetrates, and which are formed so as to face each other with a distance therebetween, and a support bar, which is perpendicularly formed at the lower side of the bracket, has the lower end of an extension pack coupled to the support bat, and which has on the rear surface thereof a support plate that comes into close contact with the bottom surface of an anchor aperture. As a result, the support member firmly fixes the fixing device, thereby preventing sliding of the coupling position of the fixing device even when colliding and coming into close contact with the bottom surface of the anchor aperture, and thus effectively allows more stable construction. In addition, removing the steel wires from the fixing device becomes much easier by means of rotating the steel wires, which are inserted into the head portion of a hex bolt to simply release a wedge, and when the steel wires are rotated in the opposite direction or when the steel wires are forcibly inserted into the fixing device, re-tensioning is effectively achieved by means of the elasticity of a first spring.</p> |
