However, since the rigidity is low, the grid frame must be made smaller than necessary, and there is a problem that the material cost is high and the construction is troublesome. In addition, a hook-type anchor whose head is bent into a U-shape is used for joining the frame members together, and the terminal portion of the frame member is fixed with the hook-type anchor by crossing the protruding horizontal streaks mutually. Not only is the joint strength not sufficient, but the hook-type anchor is often damaged during casting, and if the ground is frozen when the frame member is tied to the hook-type anchor, However, there is a problem that the stabilization of the slope is impaired because the.

されている。FIG. 3 shows a legal frame member used in the structure of the present invention. This legal frame member 1 is composed of a large number of horizontal wires 2,2 and vertical wires 3,3 joined in a lattice form by knitting or the like. It has a large number of horizontally long meshes a, is formed in a belt shape and is bent in a mountain shape, and its top 4 is formed flat, and both ends have legs 5, 5 parallel to the top 4. 5 protrudes outward.

法枠部材１の頂部とが重合することになる。The structure of the present invention is formed by assembling the legal frame members 1 as a unit member with each other. That is, as shown in FIG. 1, each of the legal frame members 1 is disposed on the legal surface with the flat top 4 facing upward. And, in the transverse direction of the slope, the law frame members 1, 1 are arranged with their legs 5, 5 superimposed on each other, and in the vertical direction of the slope, The overlapped legs 5, 5 of the legal frame members 1, 1 at the top of the top 4 of the member 1 are arranged in an overlapping manner. In other words, the legal frame members 1, 1 arranged in the horizontal direction and the legal frame members
1,1 will be arranged in a staggered pattern with each other. Accordingly, the legs 5, 5 of the row of the legal frame members 1, 1 and the top of the legal frame member 1 above the row overlap.

固着した構造のものとなっている。Then, the overlapped portions of the three legal frame members are integrally joined by using a joint fitting, and are fixed to the ground by an anchor. As shown in FIG. 4, the connecting metal fitting 6 is provided with anchor insertion frames 7, 7 which are curved and protruded to one side, and a normal frame which is bent and protruded in a V-shape in a direction opposite to the frame 7. The insertion frames 8, 8 of the connecting rods 10 of the members 1, 1 are vertically spaced from each other, and are fixed at both ends thereof by vertical streaks 9, 9.

材1,1は地山に固定されることになるのである。Then, as shown in FIG. 5, the connecting bracket 6 is passed from one side (lower side) of the overlapping portion, and the connecting rod insertion frames 8, 8 protruding to the other side are passed through the meshes a, a and the other side. By inserting the straight connecting rod 10 into the hook holes b, b formed thereby, the overlapping portions of the legal frame members 1, 1, 1 will be integrally connected, The law frame members 1, 1, 1 arranged on the slope face are connected via their overlapping portions. Then, a simple rod-shaped straight anchor 11 is inserted into the hook hole c formed by the frames 7 protruding to one side of the joint fitting 6 and is placed on the ground to be arranged. Thus, the combined legal frame members 1, 1 are fixed to the ground.

のである。In this way, the legal frame structure is installed on the slope, and the peripheral portion thereof has a linear shape as a member for forming the peripheral portion, as illustrated in FIG. Using the outer frame material 12 of the mesh plate, and joining it to the legs 5, 5 of the legal frame members 1, 1 as shown in the figure, or the top of the legal frame members 1, 1 and other appropriate locations , And joined together using the joint fitting 6 in the same manner as described above, and fixed to the ground with the anchor 11.

性を発揮することになる。After the construction of the framing structure as described above,
Fill the soil into each of the legal frameworks. This completes the slope protection. The earth pressure due to the filled soil is applied to each of the frame members 1 and 1. However, since each of the law frame members 1 has a mountain shape, the supporting force is large and each of the law frame members 1 is lower. Since it is supported at the top of the side frame member, the structure as a whole exhibits excellent strength and rigidity.
（考案の効果） 本考案の法枠構造物は、上述のように構成されている
ので、次のように優れた効果を奏するものである。(Effects of the Invention) Since the legal framework structure of the present invention is configured as described above, it has the following excellent effects.
（１）各法枠部材は山形となっているので、それぞれに
土圧への対抗力が大であり、しかも、各法枠部材は横方
向に配列して互に結合されると共に、その結合部は次段
の法枠構造物の頂部と結合されているので、法枠構造物
全体として大きな強度、剛性が発揮されることになる。
したがって、法枠個々の形を大きく設定でき、使用資材
の節減が図れる。(1) Since each law frame member has a mountain shape, the opposing force against the earth pressure is large, and each law frame member is arranged in the lateral direction and is connected to each other. Since the portion is connected to the top of the next frame structure, large strength and rigidity are exhibited as the whole frame structure.
Therefore, the shape of each legal frame can be set large, and the material used can be reduced.
（２）法枠部材は網板製で軽量であると共に各法枠部材
の結合個所が少なくできるので、施設作業が容易であ
る。(2) The legal frame member is made of a net plate, is lightweight, and can reduce the number of connecting points of the legal frame members, so that facility work is easy.
（３）法枠部材が網板製であるから、通水性と通気性に
優れると共に、植生の根がらみもよく、また、地山の凹
凸にもよく順応でき、法面の保護、安定化が良好にでき
る。(3) Since the method frame member is made of mesh plate, it is excellent in water permeability and air permeability, it has good rooting of vegetation, and it can well adapt to unevenness of the ground, protecting and stabilizing the slope. Can be good.
（４）鉤枠を突設した結合金具の使用により、各法枠部
材の結合力が大であると共に、結合作業が簡便である。
また、従来のような頭部を鉤形としたアンカーを使用せ

打設作業が容易になるばかりでなく、寒冷地での施設に
おいても、凍結によるアンカーの浮き上りにより、法枠

ける施設にも広く適用できる。(4) The use of the joint fitting with the hook frame protrudes makes it possible to increase the joining force of each leg frame member and simplify the joining operation.
Also, instead of using a conventional anchor with a hook-shaped head, it is only necessary to place a straight anchor, which not only facilitates the work of placing the anchor, but also in facilities in cold regions. However, since the floating of the anchor due to freezing does not cause lifting of the frame structure, it can be widely applied to facilities in cold regions.
