Description of Invention (6) 3 d. The joint 3 c is formed at the lower edge end portion and one side edge end portion, and the joint 3 d is formed at the upper edge end portion and the other side edge end portion, and is continuously formed in the circumferential direction. In addition, since the joints 3 c and 3 d are fastened to each other between the wall surface plates 3 and 3 adjacent to each other in the up-down direction and the horizontal direction, the positioning of the wall surface plate 3 becomes easy, and the earth material can be reliably prevented during rolling. Part 1 flows out from the adjacent wall surface plates 3, 3, or the wall surface plate 3 is displaced or moved out of the surface due to earth pressure. Even a thin wall surface plate can still build a very stable wall surface. As another example of the wall surface flat plate, it can be formed into a substantially hexagonal plate shape as shown in FIGS. 3 (a) to (e).

Explanation of the invention (7) So, because the wall surface plate 7 is formed into a hexagonal plate shape, and because the corner "4" is an obtuse angle, it is not easy to be stressed, and the earth pressure will be even Into. Therefore, "<" in the corner portion is not easily broken, and the contact surface can be increased to make it difficult to fall off. Here, the wall surface plate may be formed into a square shape, an inverted T shape or a cross shape as usual. For the material of the wall slab, in addition to the concrete slab, for example, glass fiber, carbon fiber, or fiber reinforced with steel fiber can be used to reinforce the concrete. This is because these wall plates reinforced with reinforcing fibers can be made lighter by thinning them due to their higher strength. They can be implemented especially in mountain engineering without the use of heavy machinery. The receiving metal member 4 is provided on the back surface of the reinforcing rib 3b with a plurality of protrusions at predetermined intervals in the vertical direction. The receiving metal piece 4 is formed into an L-shape as shown in Figs. 4 (a) to (d), and each has a longitudinally longer connecting hole 4b on one flange 4a.

In this case, the connecting hole 4 b may be a circular hole. In addition, the end portion of the supporting metal member 4 may also cover a considerable length of concrete embedded in the wall slab 3. As shown in, for example, FIGS. 4 and 8, the connecting hardware 5 has a connecting plate 5 a or a connecting ring 5 b, and a connecting plate 5 a has a connecting hole formed on one end side of the connecting plate 5 a. 5 c and assemble the connecting nut 5 d on the other end side to form the former. The connecting nut 5 d is a long nut or the like, and the connecting nut 5 d is welded to the notch 5 e formed by the other end side of the connecting plate 5 a, or as shown in, for example, FIG. 4 (d) Assembled only by welding to the side part of the other end side of the connecting plate 5a. However, since the connecting plate 5a of the former method is consistent with the material axis of the connecting nut 5d, it is better to avoid partial cores. The connecting metal member 5 thus formed is assembled to the end portion of the reinforcing material 2 by screwing the male screw portion 2 a formed on the end portion of the reinforcing material 2 to the end portion of the reinforcing material 2. One end of a is inserted between the flange portions 4 a and 4 a of the supporting metal piece 4, and the connecting bolt 14 is locked to the connecting hole 5 c of the connecting plate 5 a and the connecting hole 4 b of the supporting metal piece 4.

Description of the invention (9) At this time, the connection nut 5 d and the connection plate 5 a are rotated together and the connection metal piece 5 is properly adjusted to the wall surface After the protruding length on the flat plate 3 side, one end side of the connecting plate 5 a is connected to the support metal 4. Thereby, the inclination of the wall surface plate 3 or the slack between the wall surface plate 3 and the reinforcing material 2 can be eliminated, and the installation and adjustment of the wall surface plate 3 can be easily performed. Figs. 8 (a) and (b) show the case where the connecting plate 5a is used instead of the connecting plate 5a, and a connecting metal piece having a U-shaped or ring-shaped connecting ring 5b is used instead. In this case, the space 5f will function as a connection hole 5c formed by the connection plate 5a for inserting a connection bolt, or as a notch 5e for welding the connection hole 5c and the nut. As the reinforcing material 2, there are also a rod-shaped material such as a steel bar and an arch-shaped anchoring body 6 as shown in Figs. 9 (a) to (c), as shown in Figs. 10 (a) to ( e) As shown in the figure, an arch-shaped anchoring body 6 is provided at the end and a belt-shaped material such as steel strip is used. This type of reinforcing material 2 is a U-shaped belt-shaped surface that is pulled by resistance, but because the bending force does not work, only the pulling force works. Compared with the reinforcement of the reinforced steel frame that the bending force works, etc. The amount of material used at the time of the material can be small, and the weight of the used material can be reduced, and it is particularly superior to the workability of mountain engineering. In addition, for example, a reinforced grid, a metal mesh, or a Giotto pattern as shown in Figs. 11 (a) to (c) is used, and in any case, it is provided with a screw on the end of the wall plate 3 side.

Description of the invention (11) The stress on the connecting part a between the wall surface plate 3 and the reinforcing material 2 will not be concentrated, so the connection can be reliably prevented The damage of the part a, the displacement of the wall surface plate 3, and the like. As a result, the use of a thin wall surface plate 3 having a slip function and extremely stable stability becomes possible, which is superior to workability and economical construction of a reinforced soil structure. As for the anchoring metal member 6, in addition to those formed only in a rectangular plate shape (pressure bearing plate) as shown in FIG. 4, the anchoring metal member 6 may be used particularly when the earth material 1 is rolled, By being pressed against the wall surface plate 3 in the opposite direction, the tension can be introduced into the reinforcing material 2. For example, when the side view shown in FIG. 12 (a) is slightly ^ < ", or formed as As shown in Figures 12 (b) and (c), the rectangular or circular plate shape has a central portion bulging toward the wall surface plate 3 and a peripheral portion facing the wall surface plate 3, or In the case of reinforcing materials made of rod-shaped materials such as steel bars, the ends of the reinforcing material 2 are bent into a triangular shape as shown in FIG. 12 (d), and for example, FIG. 12 (e ), (F) as shown in the figure are formed by strips and the like as arches.

Description of the invention (12) Because of the large drawing resistance obtained by weight, the effects of economy, continuity, and workability can also be obtained. On the other hand, if the anchor body 6 having such a shape is pressed into the soil material 1, because of its shape, it is difficult to install the anchor body 6 on the wall surface plate 3 and the anchor body 6 differently from a flat plate. Slack is likely to occur on the reinforcing material 2 in between, and the wall surface is easily displaced. However, such a disadvantage can be eliminated by using the connecting portion of the present invention. Figs. 8 and 9 show examples of assembly of the anchor body 6 formed in an arch shape. When a rod-shaped material such as a reinforcing bar is used as the reinforcing material 2, Figs. 8 (a) to (c) As shown in the figure, the assembling holes formed at both ends of the anchoring body 6 are respectively inserted through the adjacent reinforcing materials 2 and are assembled by means of strong clamping by using a fixed nut 17 from the front and the rear. In the case where a strip-shaped material such as a strip steel is used as the reinforcing material 2, as shown in FIGS. 9 (a) and (b), both ends of the anchoring metal piece 6 are fixed with bolts 1 8 The bolts are respectively assembled to the ends of the adjacent reinforcing materials 2 to be assembled. In this way, the anchor body 6 assembled to the reinforcing material 2 is a semicircular shape because the warp shape has a large occlusal strength and can securely fix the wall plate 3.

Description of the invention (15) In the present invention, the connecting plate 5 a (or the connecting ring 5 b) After adjusting the protruding length of the connecting plate 5 a in the circumferential direction of the male spiral portion 2 a by half a revolution, that is, 0.5 mm, and by 1 mm per rotation / rotation, the connecting plate 5 a can be connected to the wall plate 3 Therefore, after temporarily removing the connecting plate 5 a from the supporting metal 4 and rotating it 11 times in the circumferential direction of the male spiral portion 2 a, if the connecting plate 5 a is connected to the wall surface plate 3 again, the wall surface can be correctly made. The slab 3 stands 5 · 5 mm. Immediately, the connecting part can be adjusted with a simple structure and simple workability. In the following way, the wall plates 3 c of the third and fourth sections are alternately arranged in the same manner with the reinforcing material and the soil material to construct the entire reinforcing soil structure. In such a construction, even in particular, the soil material 1 The reinforcing material 2 is lowered along with the settlement of the soil material 1 by rolling, etc., and the connection portion is still not easy to be damaged, especially because the connection hole 4 b is used as a growth hole, and the end portion of the reinforcement material 2 can be along the supporting metal piece 4 Because the connection hole 4 b slides downward, the stress is not concentrated on the connection portion a of the wall surface plate 3 and the reinforcing material 2, so the connection portion a is not damaged or the wall surface plate 3 is not inclined. Figures 14 (a) and (b) show other examples of the reinforced soil structure of the present invention. In particular, the front end of the reinforcing material 2 made of rod-shaped materials such as steel bars is shown in Figure 14 (b). The anchoring body of the structure 18 is fixed to the mound. In the case of a structure in which the anchor body is fixed to the mound, a part of the reinforcing material between the anchor body and the wall plate is liable to loosen and deform due to the instability of the mound. However, due to the use of the connecting part of the present invention, the paper size can be eliminated. The Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable.

In the figure, the front ends of the plurality of reinforcing members 2 extended on the mound side are connected to each other by fixed rods 19 made of profiled steel such as angle steel, and the fixed rods 19 are connected by concrete or mound in the mound. Anchor body 21 to which cement grout 20 is fixed. The other structures are the same as those described in the first figure. [Effects of the Invention] As described above, the present invention relates to the wall material provided at the front end of the soil material, and the reinforcing material provided in the soil material, respectively. The connection plate or ring supporting the metal member protruding from the back part is connected with the connecting metal member screwed to the connection nut of the male screw portion protruding from the reinforcing material at the other end. When the reinforcing material is connected to the back surface of the wall surface material, one end of the connection plate is connected to the supporting metal component by appropriately adjusting the protruding length of the connection metal piece on the wall surface plate side by appropriately rotating the connection nut, thereby eliminating the wall surface. The inclination of the flat plate, or the slackness between the wall flat plate and the reinforcing material, and the effect of simply installing and adjusting the wall flat plate. In addition, the connection metal parts can be formed by assembling the connection holes only on one end side of the connection plate, and the connection nut can be formed on the other end side. Since the process such as processing is not required at all, it can be easily produced on site and can achieve engineering costs The effect is greatly reduced.
