Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope block for laying on a cut or embankment of a river, a road or the like to construct a firm slope.

[0002]

2. Description of the Related Art As a slope block, there is known a sloped concrete body in which inclined walls are formed at four corners of a rectangular concrete body and a connecting ring is protruded from the inclined walls (for example, Japanese Patent No. 930290, Japanese Patent No. 930290). JP-A-7-173818,
JP-A-9-170221).

[0003] This type of slope block is laid in a grid pattern on cuts or embankments such as rivers and roads, and binding rings protruding from the slopes at the four corners of each block are bound with a connecting fitting such as a shackle. Thus, the entire blocks are connected to form a straight slope. However, when this is to be laid on curved cuts or embankments such as rivers and roads, as shown in FIG. 5, the upper block is shifted laterally with respect to the lower block, and four connecting rings are used. Will not match. For this reason, there is a disadvantage that the connection of the upper and lower blocks becomes impossible.

A revetment block is known in which ring-shaped connecting hooks are provided on the outer periphery of a concrete block of an arbitrary shape at an appropriate interval, that is, at an interval of about 5 cm at which binding work can be performed by a connecting fitting (for example, see, for example). JP-A-9-
296432).

When the main body of the revetment block is formed in a square shape and connection hooks are provided on the outer periphery thereof, the connection hooks are butt-connected to each other and bound with connection fittings. , Resulting in an interval of 10 cm or more. Therefore, there is a drawback that the earth and sand filled in the space flows down due to rainwater. Further, since the lattice pattern is emphasized by this interval, there is a disadvantage that the appearance of the slope is impaired.

[0006] Further, the revetment block can be connected even if it is displaced vertically or horizontally, but if the surface of the earth and sand before the block is laid is uneven, a sheet or the like is laid on the upper surface thereof. Also, the connecting hook of each block is displaced in the thickness direction. For this reason, even if the connecting hooks are correctly bound with the connecting metal fittings, a large displacement occurs in the binding portion later, and each block is distorted up, down, left and right, and the appearance of the slope may be impaired. . Also, there is a similar danger due to slight ups and downs of the surface of the cut or the like after the laying.

[0007]

SUMMARY OF THE INVENTION The present invention has been developed in view of the above-mentioned drawbacks of the conventional block for slopes. Even when cuts or embankments such as rivers and roads are straight, they are also curved. It is intended to provide a slope block that can be laid out neatly even in the case where the slope is built.

[0008]

SUMMARY OF THE INVENTION A slope block according to the present invention comprises connecting rods arranged at intervals on one side wall of a concrete body having inclined walls formed at four corners, and bent portions formed at both ends thereof. The right and left inclined walls are embedded in the concrete body, and the outside of the left and right inclined walls on the other side walls are characterized by a U-shaped connecting ring projecting from the inclined wall into the concrete body. I have.

[0009] A large number of the slope blocks constructed as described above are placed on a cut or embankment formed in a straight river or a road, with the connecting rods on the upper side or the lower side, and from the lower stage to the upper stage. , And the bent portion of the connecting rod and the connecting ring are tied together by connecting metal fittings as shown in FIG. In this case, the upper block is shifted laterally with respect to the lower block as shown in FIG. 4, and the connecting ring and the connecting rod are bound by the connecting metal fitting, thereby constructing a linear slope having a different appearance. .

On a cut or embankment formed on a curved river or a road, the connecting rods are laid in order from the bottom to the top with the connecting rods on the upper side or the lower side, and connected as shown in FIG. By tying the rod and connecting ring with connecting metal fittings,
Build a curved slope.

The concrete body having inclined walls at the four corners may be a plate having a substantially square plate shape with each side wall being flat or uneven, a plate in which pseudo stones are integrally protruded on this plate, or a plurality of pseudo stones. Are arranged in a substantially square shape, and each pseudo stone is connected by a reinforcing bar or the like in a matrix form.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 5 show an example of a block for a slope made of a plate-shaped concrete body. A grid-like reinforcing bar 2 is embedded in a concrete body 1 and inclined walls 3 are provided at four corners. Is formed. In FIG. 1, a connecting rod 4 is provided above the concrete body 1 at a predetermined interval.
The bent portions 5 formed at both ends are embedded in the concrete body from the left and right inclined walls 3 and fixed to the reinforcing bar 2. A U-shaped connecting ring 6 protrudes outside the inclined walls 3 formed on the lower left and right sides of the concrete body 1, and both ends thereof are fixed to the reinforcing bar 2.

A large number of the slope blocks constructed as described above are sequentially laid from the lower stage to the upper stage on cuts or embankments of rivers and roads with the connecting rod 4 facing upward or downward. Then, as shown in FIG. 3, if the bent portion 5 of the connecting rod 4 and the connecting ring 6 are bound by the connecting metal fitting 7 of Japanese Patent No. 2950374, for example, a linear and firm slope is constructed.

As shown in FIG. 4, the connecting rod 4 and the connecting ring 6
Are connected by the connection fitting 7 and the bent portions 5 of the connection rod 4 are connected to each other by a connection fitting 7a such as a shackle, for example, so that a curved slope is constructed as shown in FIG.

In the above laid state, the connecting rod 4 abuts on the outer wall of the adjacent concrete body 1 and the interval between the joints between the concrete bodies 1 is always constant, so that a slope having a good appearance is formed. Is done.

FIGS. 6 to 9 show an example of a block for a slope made of a matrix-shaped concrete body. In the concrete body 11, a plurality of pseudo stones a are arranged so as to be substantially square in shape. Each of the pseudo stones a is connected by a connecting portion b covering the reinforcing bar 12 therebetween, while being connected by the reinforcing bar 12. Further, rulers 13a having inclined walls 13 are formed at the corners of the pseudo stone a at the four corners.

In FIG. 6, connecting rods 14 are disposed at a predetermined interval above the concrete body 11, and bent portions 15 formed at both ends thereof are embedded in the pseudo stone a from the left and right inclined walls 13 respectively. And is fixed to the reinforcing bar 12. An inclined wall 1 formed on the left and right of the lower side of the concrete body 11
A U-shaped connecting ring 16 protrudes from the outside of the tube 3, and both ends thereof are fixed to the reinforcing bar 12.

A large number of slope blocks constructed as described above are sequentially laid from the lower stage to the upper stage on cuts or embankments of roads or rivers with the connecting rod 14 facing upward or downward. Then, as shown in FIG.
If the connecting ring 5 and the connecting ring 16 are bound together by the connecting bracket 17, a straight and firm slope is constructed.

Further, as shown in FIG. 9, the connecting rod 14 and the connecting ring 16 are bound by a connecting bracket 17, and the bent portion 15
If they are bound together by a connection fitting 17a such as a shackle, a curved slope is constructed as shown in FIG.

In the straight or curved laying state, the connecting rod 14 abuts on the adjacent concrete body 11, particularly the outer wall of the ruler portion 13a, and the interval between the joints between the concrete bodies 11 is always constant. A slope with good appearance is formed.

The slope block according to the present invention can be connected to blocks having connecting rings of different sizes and blocks having different shapes by using the connecting rods 4 and 14. In FIG. 1 and FIG. 6, when laying on cut or embankment so that the connecting rods 4 and 14 are oriented vertically to the left or right, they can be connected to a block for stairs.

[0022]

The slope block according to the present invention comprises a connecting rod provided on one side wall of one concrete body and a connecting ring projecting on both left and right inclined surfaces of the other side wall of the other concrete body. By tying, many blocks were laid on cuts or embankments such as rivers and roads in a grid (potato joints) or so-called break joints with vertical joints shifted left and right, and straight or curved. You can build a solid slope.

Even if the cut or embankment has some irregularities, or if the cut or embankment may have irregularities thereafter, the connecting rod abuts against the outer wall of the adjacent concrete body, and the concrete body and concrete are removed. Since the distance between the joint and the main body does not change, a slope having a good appearance can be constructed over a long period of time.
