The present invention relates to a bidirectional resistance anchor which, more specifically, can apply higher anchoring force to the same ground and can be used for the ground with low strength by reducing the maximum load imposed on a grout as an anchoring place is divided into multiple anchoring places and the anchoring force is distributed to each divided anchoring place and, consequently, focused load is reduced. The bidirectional resistance anchor comprises: a tension body which has a joining protrusion and a compression grip insertion groove which are formed to be symmetrical and has a support unit having a steel strand insertion hole formed on a rear side while the joining protrusion is formed on a front side, protrudes toward the outside, and has an insertion hole for allowing a screw rebar to be inserted therein and the compression grip insertion groove are formed on both lateral sides; a tension-type anchor body which is made of the screw rebar inserted and installed on the joining body of the tension body; a compression body which has sheath pipe insertion holes which penetrate the inside and are formed to be symmetrical and has a compression-type protrusion which is formed on a rear side and protrudes toward the outside to increase attachment force; a compression-type anchor body which fixates the steel wire covered with the sheath pipe with a compression grip by placing the steel wire in the compression grip insertion groove of the tension body; a load transfer body which is joined between the tension-type anchor body and the compression-type anchor body, has elasticity, is in a circular shape, and allow the steel wire to be inserted therein; and an anchor body case which is installed on the outside of the tension body and the load transfer body, has a hole which is formed on a front side to allow the joining protrusion to be inserted therein, has inclined sides on both lateral sides of the hole, and has an insertion space therein.
본 발명은 양방향 저항 앵커에 관한 것으로 더욱 상세하게는 정착장을 여러 개로 분할하여 앵커력을 각각의 분할된 정착장으로 분산시켜 집중 하중의 크기를 줄임으로, 그라우트에 작용하는 최대하중을 감소시켜 동일지반에 대해 더 큰 앵커력을 적용할 수 있고, 저강도 지반에 사용할 수 있는 것이다.이는 전면에 외부로 돌출되고 내부에 나사철근이 삽입되는 삽입공이 형성된 결합 돌기와 양쪽 측면에 압착그립 삽입홈을 서로 대칭되게 형성하고, 후면에 강연선 삽입공이 형성된 지지부를 갖는 인장 몸체와, 인장 몸체의 결합 돌기에 삽입 설치되는 나사철근으로 이루어진 인장형 앵커체와, 내부를 관통하는 쉬스관 삽입공이 서로 대칭되게 형성하고 후면에는 부착력 증대를 위해 외부로 돌출된 압축 돌기를 갖는 압축 몸체와, 쉬스관이 피복된 강연선을 인장 몸체의 압착그립 삽입홈에 위치시켜 압착그립으로 고정하는 압축형 앵커체와, 상기 인장형 앵커체와 압축형 앵커체 사이에 체결되며 탄성을 갖는 원형 관이며 내부에 강연선이 삽입되는 하중전달체와, 상기 인장 몸체와 하중전달체의 외면에 설치되며 전면에 결합 돌기가 삽입되는 구멍이 형성되고 구멍의 양측에 경사면이 형성되며, 내부에 삽입 공간을 갖는 앵커체 케이스가 체결되는 것을 특징으로 한다.
