CONSTITUTION:Plate members 12 composed of a steel plate, etc., and having specified width are disposed in upright along the side faces of the plate members 12 while being crossed and arranged crosswise and being unified, and a boss section 14 having a reinforcing-bar inserting hole 15 at a center is mounted, thus forming a latticed slope-face plate 10. A slant face is drilled, and reinforcing bars are inserted into the drilled holes while a grout material is impregnated. The slope-face plate 10 is inserted to the exposed-side end section of the reinforcing bar projected from the slant face through the reinforcing-bar inserting hole 15, and a nut is screwed and the plate 10 is fixed onto the slant face.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope plate used in a slope reinforcing method for driving a steel rod to reinforce a slope.

[0002]

2. Description of the Related Art A reinforcing bar-reinforced earthwork method is known as one of slope reinforcement methods for preventing loosening and collapse of slopes.
In this method, as shown in FIGS. 3 (a) and 3 (b), for example, a ground E forming a slope is drilled, a steel rod, that is, a reinforcing bar 2 is inserted therein, and a grout material 1 is injected. Reinforcing bar 2 that hardens the periphery of rebar 2 and projects from the slope
A slope plate 3 having a side of about 10 to 15 cm is inserted through the exposed end of the above, and a nut 4 is screwed in to fix and fix the slope plate on the slope. Further, a lath steel 5 for covering the slope and reinforcing the sprayed concrete 6 is stretched, and the lath steel 5 is fixed to the slope by the slope plate 3.

According to this method, the weakness of the ground E is compensated by the tensile force and the shearing force of the reinforcing bar 2 so that the respective characteristics of the ground and the reinforcing bar 2 can be effectively utilized mutually. Mountain E can be strengthened. Further, in this construction method, the larger the fixing area of the slope plate 3, the greater the reinforcing effect of the reinforcing bar 2. Therefore, in order to increase the reinforcing effect of the reinforcing bar 2, it is desirable to further increase the fixing area of the slope plate 3. Be done.

[0004]

However, when the area of the slope plate 3 is increased, the earth pressure applied to the slope surface plate 3 is increased. Therefore, it is necessary to increase the rigidity of the slope surface plate 3 to counteract the increase in the earth pressure. Occurs. Then, in order to increase the rigidity of the slope plate 3, it is necessary to increase the thickness thereof, but if the thickness is increased, the weight of the slope plate 3 increases, and therefore the workability on the slope becomes worse. Occurs.

Therefore, the present invention has been made to solve the above problems, and its object is to increase the fixing area and the rigidity of the steel rod without increasing the weight of the slope plate as much as possible. (EN) Provided is a slope face plate which can sufficiently provide a reinforcing effect and which can be easily attached.

[0006]

The present invention has been made in view of the above object, and the gist thereof is to support the earth pressure of a slope by a steel rod driven into the slope such as a natural ground or cut soil. A slope plate for pressing down a slope, which is used in a slope reinforcement method, wherein the slope plate is a plate member having a predetermined width set upright along the side surface of the slope plate, which is vertically and horizontally combined to form a lattice. The slope plate is characterized by being configured by

Here, the combination of the plate members in the vertical and horizontal directions means, for example, that a plurality of plate members are cross-arranged and integrated to manufacture them, or they are integrally formed in a lattice shape using a mold or the like. Good.

[0008]

According to the above slope plate, the plate members which are erected along the side surface are vertically and horizontally combined and integrated, so that the fixing area on the slope is increased and the rigidity thereof is increased. Even if the thickness is increased, a large number of openings are formed between the plate members arranged in a grid shape, so that the increase in weight is small. Therefore, the mounting work on the slope can be facilitated, and the steel rod can be fixed and fixed to the slope over a wide area to sufficiently exert the reinforcing effect by the steel rod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 (a) and 1 (b) show a reinforcing bar-reinforced earthwork method using a lattice-shaped slope plate 10 according to the present invention. In the drawings, the same parts as those of the conventional one are designated by the same reference numerals, and different parts are designated by different reference numerals.

In the reinforcing bar reinforced earth work method shown in the figure, a slope is drilled, a steel rod, that is, a reinforcing bar 2 is inserted therein, and a grout material 1 is injected to surround the reinforcing bar 2 in the same manner as the conventional method. The side of the exposed side of the reinforcing bar 2 that is hardened and further protrudes from the slope has a side of 10 to 100 cm and a thickness of 7 to 10 cm.
A lattice-shaped slope plate 10 of a certain size is inserted, and the nut 4 is screwed in to fix and fix it on the slope. Further, a lath steel 5 for covering the slope and reinforcing the sprayed concrete 6 is stretched, and the lath steel 5 is fixed to the slope by the slope plate 10.

In the lattice-shaped slope plate 10 according to the present invention, as shown in an enlarged view in FIG. 2, a plate member 12 made of, for example, a steel plate and having a predetermined width is erected along the side surface thereof. It is constructed by vertically and horizontally crossing and integrating, has a larger fixing area than the conventional slope plate, and has a predetermined thickness corresponding to the width of the plate member 12, thereby supporting the plate member 12. It has sufficient rigidity to resist earth pressure. On the other hand, since the inside of the slope plate 10 is composed of a space partitioned by the plate member 12, that is, a large number of openings, the weight thereof is lightweight despite having a large fixing area and rigidity, and therefore the fixing installation work on the slope is performed. Can be done easily. Further, a boss portion 14 is formed in an opening located at the center of the slope plate 10, and further, a reinforcing bar insertion hole 15 penetrating the center of the boss part 14 to be inserted into the exposed end of the reinforcing bar 2. Has been pierced.

Further, in the reinforcing bar reinforced earth method using the lattice-shaped slope plate 10 having the above structure, since the slope plate 10 has a large area to be fixed on the slope, the reinforcing effect of the slope by the reinforcing bar is sufficiently exerted. In addition, it has sufficient rigidity and does not deform due to earth pressure.

When the concrete 6 is sprayed onto the slope including the grid-like slope plate 10, the gap between the lattices is filled with the concrete 6 to form a slope excellent in function and aesthetics. You can

[0014]

As described above in detail, according to the slope plate according to the present invention, it is possible to increase the fixing area to the slope and the rigidity while suppressing the increase in weight, so that the slope is reinforced by the steel rod. The effect can be easily enhanced.
That is, the slope deformation can be suppressed and the loosening of the ground due to excavation can be efficiently performed, and the pitch of the steel rods can be increased or the length of the steel rods can be shortened to economically increase the slope. Can be reinforced.
