を施工する工法がある。2. Description of the Related Art As one of the construction methods for reinforcing slopes such as roads and landscaping, after laying a mesh body such as a wire mesh on the slope, arranging reinforcing bars and coils in a grid pattern on the mesh body, After this, there is a construction method in which mortar is sprayed so as to fill the grid-shaped reinforcing bars and coils, and a grid-shaped method frame containing reinforcing bars is constructed on the slope.
【0003】この工法によれば、法枠が格子状であって
縦横に連続していることから、法面表層の剥落に対して
強い抵抗力を発現させることができる。According to this construction method, since the method frame has a lattice shape and is continuous in the vertical and horizontal directions, it is possible to exert a strong resistance against the peeling of the surface layer of the slope surface.

場合があり、このことから本発明者は、格子状鉄筋の交
差部にアンカーを設置することを思いついたのである。However, in the above-mentioned construction method, the resistance force for suppressing the peeling off of the surface layer of the slope depends only on the weight of the lattice-shaped slope frame made of mortar, so that the resistance force may be insufficient on a steep slope. From this, the present inventor came up with the idea of installing an anchor at the intersection of the grid-shaped reinforcing bars.

盤に伝えさせる。That is, at the intersection of the grid-like reinforcing bars, a hole for anchor installation is drilled so as to reach the hard ground, the anchor is inserted through this anchor hole, and further, the anchor hole is filled with grout to anchor it. While fixing the anchor, a spacer structure for fixing the anchor is installed so that the head of the anchor is exposed on the upper side of the grid-shaped method frame by spraying mortar, and then the nut is screwed onto the anchor. , This nut is screwed so that it comes into contact with the bearing member of the spacer structure, and further the nut is screwed to compact the anchor, so that the bearing member acts as a reaction member and tension is applied to the anchor. It is applied and the tension applied to the anchor is transmitted to the ground.

施工性の面で改善の余地があった。However, depending on the slope, it may take a large number of long anchors to reach the anchor to a deep hard ground, and as an anchor, generally, a nut is used. For example, a threaded bar that can be screwed is used. However, the threaded bar becomes heavier as it becomes longer, so that there is room for improvement in terms of handling and workability.

になる点で好適であるとの結論に達したのである。As a result of further intensive research and development, the present inventor has improved handling and workability by selecting a non-metallic lightweight rod-shaped member such as fiber as the anchor. In addition to that, it is concluded that it is suitable in that rust prevention treatment is unnecessary.

Although it is possible to easily apply tension to the anchor, it is technically impossible to tighten the nut with a rod-shaped member made of fiber, etc., and it is not possible to apply tension to the rod-shaped member. There was no way to make it happen.
