Zusammenfassung:The present invention relates to an anchor fixing device capable of visually identifying anchor tension, which can monitor changes in tension of a tension member installed to reinforce the ground such as a slope, thereby facilitating easier maintenance of the tension member, and, more specifically, to an anchor fixing device capable of visually identifying anchor tension, in which an upper plate of a reaction force jig provided outside an anchorage device through which a tension material penetrates, and the anchorage device are mutually coupled by indicator bolts, and the colors of indicators provided on the upper surfaces of the bolt heads of the indicator bolts change according to the magnitude of tension force acting on the tension material. The anchor fixing device for fixing a head part of the tension material to which tension force is applied comprises: an anchorage device having a through-hole formed in the center thereof to pass the tension material; a fixture provided on an upper part of the anchorage device to fix an end part of the tension member; a reaction force jig having a cylindrical shape of which a lower part is open so that the anchorage device is accommodated thereinside, having an insertion hole for exposing the upper part of the anchorage device to an upper part thereof, and having the lower surface of an upper plate and the upper surface of the anchorage device to be distance from each other; and a plurality of first indicator bolts each including a bolt head and a bolt body, the bolt head being provided on an upper part of the upper plate of the reaction force jig, and the bolt body being screw-coupled to the anchorage device through the upper plate of the reaction force jig, wherein a first indictor is provided on the upper surface of the bolt head to change the color when the magnitude of the tension acting on the bolt body is less than or equal to first tension. 본 발명은 사면 등 지반 보강을 위해 설치된 긴장재의 긴장력 변화를 모니터링하여 긴장재의 유지 관리가 용이한 앵커 긴장력의 육안 식별이 가능한 앵커정착장치에 대한 것으로, 더욱 상세하게는 긴장재가 관통하는 정착구 외부에 구비된 반력지그의 상판과 정착구를 지시볼트에 의해 상호 결합하되, 긴장재에 작용하는 긴장력의 크기에 따라 지시볼트의 볼트헤드 상면에 구비된 표시자의 색상이 변하는 앵커 긴장력의 육안 식별이 가능한 앵커정착장치에 대한 것이다. 본 발명은 긴장력이 도입되는 긴장재의 두부를 고정하기 위한 것으로, 상기 긴장재가 관통되는 관통공이 중앙에 형성된 정착구; 상기 정착구의 상부에 구비되어 긴장재의 단부를 고정하는 고정구; 상기 정착구가 내부에 수용되도록 하부가 개방된 원통 형상이고, 상부로 상기 정착구의 상부가 노출되는 삽입공이 형성되며, 상판의 하면과 정착구의 상면이 서로 이격되도록 구비되는 반력지그; 및 볼트헤드와 볼트몸체로 구성되어, 상기 볼트헤드는 반력지그의 상판 상부에 구비되고 볼트몸체가 반력지그의 상판을 관통하여 정착구에 나사 결합되는 것으로 상기 볼트헤드의 상면에는 볼트몸체에 작용하는 긴장력의 크기가 제
