Abstract
Disclosed herein is a ground anchor body having a rotation release structure. The ground anchor body includes a waterproof cap, a head coupler, a wedge, a tubular guide, a movable body, and a compression spring. The head coupler is coupled to a lower end of the waterproof cap. A tapered hole is longitudinally formed in the head coupler. The wedge is disposed in a tapered hole of the head coupler to hold the PC strand. The guide is installed in the waterproof cap. A slide slot is longitudinally formed in the guide. The movable body is disposed in the guide and provided with a slide protrusion inserted into the slide slot. The wedge is coupled to the movable body, and a key depression is formed in the movable body so that an end of the PC strand is key-coupled to the movable body. The compression spring elastically compresses the movable body downward.
