PS Prestressing Steel ancher nail method

CHOI HONG YONG

The present invention relates to a nail anchor structure using a prestressing steel (PS) stranded wire, and more particularly to a nail anchor structure using a PS stranded wire in which an anchor body is stably positioned in the center of an anchor anchorage section consisting of a stranded wire, a rope-shaped steel bar and a coupler, and a reinforcement tool for increasing shear and tensile force is provided to increase an anchorage fixing force of the anchor anchorage section, thereby significantly increasing a ground reinforcement efficiency. In addition, the nail anchor structure using a PS stranded wire is easy to manufacture and a distinction between free and fixed lengths, which are directly related to the quality of anchor products, is clear to facilitate quality control. The present invention includes a steel pipe nail part and an anchor fixing part.

본 발명은 PS(Prestressing Steel)강연선을 이용한 네일 앵커 구조체에 관한 것으로, 더욱 상세하게는 강연선과 로프형강봉 및 커플러로 구성되는 앵커정착부에 앵커체를 안정적으로 중앙에 위치시키며 전단력과 인장력 증대를 위한 강화구를 구비함으로서 앵커정착부의 정착 고정력을 높여 지반보강 효율을 현저히 증대시킬 수 있으며, 제작이 용이하고 앵커제품의 품질과 직결되는 자유장부와 정착장부의 구분이 확실하여 품질관리가 용이하도록 한 PS(Prestressing Steel)강연선을 이용한 네일 앵커 구조에 관한 것이다.
