Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete building block installed on a slope to protect the slope of embankment or cut soil and to plant and green the slope.

[0002]

2. Description of the Related Art Conventionally, as a concrete building block for slope greening, there is known a block having a regular hexagonal surface with a plurality of openings formed therein and utilizing these openings for planting and greening. I have.

[0003]

A conventional building block having a plurality of openings has a structure in which rainwater falling on the surface of the stacked retaining wall is difficult to permeate into the building block. It is also cut by the backfill crushed stone layer and drainage drainage, and it is difficult to reach around the pile block.

[0004] For this reason, the opening for planting is easily dried, and it is necessary to artificially supply water. Providing a plurality of openings on the surface of the block not only complicates the formwork structure for forming the openings, but also requires changing the shape and number of the notches on the back surface of the block. The use of formwork has been forced, which has led to a drop in the productivity of the building blocks.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a concrete shape of a concrete building block allows effective use of rainwater falling on the surface of a stacked retaining wall. In addition, the object of the present invention is to solve the problem of insufficient water around the stacking block, to enable the manufacturing of the stacking block by the immediate demolding method, and to improve the productivity of the stacking block.

The concrete building block of the present invention comprises:
The specific shape and structure differ depending on the surface shape (rectangular or hexagonal symmetrical in the vertical and horizontal directions) and the stacking direction of the blocks (diagonal direction or diagonal direction, or cloth or valley). 1 to 5 are described separately, but the points are common and will be described without particular distinction.

The first point of the present invention is that instead of providing an opening for planting and greening on the surface of the building block, a portion corresponding to the opening is moved to each apex, and each apex is provided at each apex. This is a point provided with a notch. The notch at each apex portion forms an opening for planting and greening together with the notch of an adjacent pile block. The cross-sectional shape of the notch is appropriately determined to be a shape convenient for molding, such as an arc, a square, or a triangle.

In the stacking block of the present invention, since there is no opening penetrating the surface, the number and shape of the notches on the back side of the stacking block need to be changed in any way from the number and shape of the notches of the general stacking block. Instead, one or two rows of trapezoidal notches are provided along the stacking direction. And the nut for connecting with the steel plate which is the earth wall reinforcing material may be buried in the stay portion similarly to the general stacking block.

A second essential point of the present invention is that a step portion which is lower than the central portion is provided at the peripheral edge of the surface of the stacking block. This step part forms a groove integrally with the step part of the adjacent stacking block, and the rainwater falling on the surface of the stacked retaining wall flows along this groove, so a circular opening on the way without a short path And is absorbed by the ground behind. In addition, it is absorbed by the ground on the back side through the gap between joints while flowing down.

[0010] For this reason, water is supplied to the periphery of the circular opening for planting and greening by rainfall, and there is no need to artificially supply water unless there is special circumstances.

[0011] By integrating the above first and second points,
The concrete building block of the present invention not only can be efficiently manufactured by an instant demolding method with a simple shape, but also the retaining wall surface formed by stacking can be greened without artificially supplying moisture. Becomes possible.

In the first and second aspects of the present invention, the "hexagons symmetrical in the vertical and horizontal directions" include regular hexagons, and the "rectangles" in the third and fourth aspects include squares. Of course.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

With reference to FIGS. 1 to 7, an example of a concrete building block according to the present invention will be described.

3A and 3B show an example of a laminate type block having a rectangular surface shape according to the third aspect of the present invention, wherein FIG. 3A is a front view when the surface shape is a general rectangular shape, and FIG. 3B is a front view when the surface shape is a square. FIG.

FIG. 6 shows an example of a valley-type block having a rectangular surface shape according to the present invention (a).
FIG. 3B is a front view of a general rectangular case, and FIG.

FIG. 7 is a front view showing an example of a valley-type block having a square surface and stacked diagonally according to the fifth aspect of the present invention.

As shown in FIGS. 1-4, the invention according to claims 1 and 2 is a hexagon whose surface shape is symmetrical in the vertical and horizontal directions, and has a notch 2 at each apex. In that the peripheral portion of the surface has a step portion 1 lower than the central portion. However, the stacking directions are different. In the case of FIGS. 1 and 2, the stacking is performed in the diagonal direction, whereas in the case of FIGS. 3 and 4, the stacking is performed in the diagonal direction. In order to cope with this difference in the stacking direction, a stacking block A having a shape in which the number and position of the retaining portions 3 are different, and in the case of FIGS. On the other hand, in the case of FIGS. 3 and 4, two rows of the retaining portions 3, 3 parallel to the diagonal line are formed on both sides of the diagonal line on the back surface. FIG. 1 shows a case where the buried nut 4 is not buried in the retaining portion 3.
Shows a case where the buried nut 4 is buried in the retaining portion 3, but whether or not the buried nut 4 is buried is determined by the structure of the retaining wall.

Similarly, as shown in FIGS.
The invention according to claim 4 is the case where the surface shape is a rectangle including a square , each of which has a notch 2 at each apex, and a step which is lower than the center at the peripheral edge of the surface. It is common in having a part 1. However, the stacking method is different. In the case of FIG. 5, the stacking is performed in the cloth stacking type, whereas in the case of FIG. 6, the stacking is performed in the valley stacking type. In order to cope with this difference in the stacking direction, a stacking block A having a shape different from the position and the number of the retaining portions 3 is formed. In the case of the fabric type shown in FIG. 6, two rows of stubs 3 and 3 are formed perpendicular to the opposite side, whereas in the case of the valley type shown in FIG. It is formed. Figure 7 is a invention according to claim 5, in a case where the surface shape stacked in the valley stacked-type stacked blocks A square diagonally, different from the valley stacking type general scheme of Figure 6, the diagonal on the back surface Are formed on both sides of each of the notches 3, 2 in parallel with a diagonal line.

In FIGS. 3, 4 and 7, the two rows of the notches 3 and 3 are formed on both sides of the diagonal line in parallel with the diagonal line in order to avoid the notch 2 at the apex. In this case, the two rows of the retaining portions 3, 3 are formed differently from the cases of FIGS. 1 and 2 in order to be able to cope with both the break ground stacking and the potato ground stacking. The buried nut 4 may not be buried depending on the structure of the backfilled earth wall.
