DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a method for manufacturing paving materials. Specifically, it relates to a method for manufacturing a pavement material that can be used for planting lawns and the like.

[0002]

2. Description of the Related Art When paving materials such as tiles and bricks are laid, natural green is completely lost on the paved surface. In addition, rainwater does not penetrate the surface of the earth and the sewer load increases.

Therefore, water-permeable pavement materials and blocks on which lawns can be planted have come to be used.

As a block on which lawn can be planted, there is a block having a through hole penetrating from the upper surface to the lower surface. The through hole is filled with the soil and the lawn is planted.

[0005]

When a lawn is planted using such a block having a through hole, the lawn grows poorly because the lawn root extends only in the through hole. In addition, the lawn grows only in the through holes, and the block surface is exposed in the parts other than the through holes, and the greening rate is low.

[0006]

A method for manufacturing a pavement material according to the present invention has a through hole penetrating from the upper surface to the lower surface for filling the soil, and the upper surface has an upper end portion of the through hole. A method for manufacturing a paving material, in which a concave groove for accommodating soil for reaching the side edge portion of the paving material is provided, and the bottom of the concave groove is concave, Filled with super hard kneading concrete, an upper mold having a molding surface that follows the upper surface of the pavement material was engaged with the lower mold from above, and pressure molding was performed. It is characterized by curing the body.

[0007]

In the method of manufacturing a pavement material of the present invention, when super-hard kneading concrete is filled in the molding die and pressed, the super-hard kneading concrete easily moves along the mold surface of the upper mold. As a result, it is possible to sufficiently rotate the super-hard mixed concrete in every corner of the mold, and also to sufficiently compact the cement.

EXAMPLE FIG. 1 is a perspective view of a pavement material manufactured by an example method, FIG. 2 is the same plan view, FIG. 3 is the same side view, and FIG.
The figure is a sectional view taken along the line IV-IV in FIG.

The pavement material 1 has a substantially rectangular shape in plan view, and four convex portions 2 are arranged in a square shape on the upper surface. At the center of the pavement material 1, a through hole 3 is provided which penetrates from the upper surface to the lower surface. Recessed grooves 4 are provided in the vertical and horizontal directions so as to be continuous with the through holes 3, and each convex portion 2 is formed by division.

The side surface 4a of the concave groove 4 is an inclined surface, and the bottom surface 4b is a concave curved surface that smoothly continues to the side surface 4a. The depth of the deepest portion of the concave groove 4 (depth from the top surface of the convex portion 2) is 30 mm or more.

A vertical groove 5 is provided at the center of the four side surfaces of the pavement material 1. Notches 6 extending vertically are provided at the four corners.
Is provided.

The pavement material 1 constructed in this way is
As shown in FIG. 6, they are laid out in a grid pattern on the roadbed 7. Incidentally, FIGS. 5 and 6 relate to an example of a parking lot,
8 is a paving tile that forms a passage for pedestrians.

When laid out as shown in FIGS. 5 and 6, the through hole 3
Besides, the vertical holes are also formed by the vertical grooves 5 and the cutouts 6 of each paving material 1 facing each other.

Therefore, as shown in FIGS. 7 to 9, the soil 9 is filled in the through holes 3 and the vertical holes and the groove 4, and then lawn (not shown) is planted.

As is clear from FIG. 7, the ground surface is the soil 9
Occupies a large area, and the pavement material 1 is only slightly exposed at the top surface of the convex portion 2. Therefore, the area occupied by the lawn is large, and the greening rate is extremely high (about 75% in this embodiment).

Of course, since the groove 4 is sufficiently deep, the rooting of the lawn is also good. Further, since the concave groove 4 is connected to the through hole 3 and the vertical hole, drainage is also good.

In the above embodiment, the convex portion 2 has a substantially rectangular shape, but may have various shapes such as a circle, an ellipse, a triangle and a polygon. Further, the numbers of the convex portions 2 and the through holes 3 are not limited to those illustrated.

The pavement material 1 is manufactured by molding using super-hard concrete (hard concrete having substantially no slump) and immediately demolding. That is, as shown in FIG. 10, the cemented concrete 12 is filled in the lower mold consisting of the bottom mold 10 and the side mold 11, and the upper mold 13 is fitted from above to perform pressure molding. Immediately after completion of pressurization, the mold is removed and cured.

By performing this immediate mold release, the use efficiency of the mold becomes high and the manufacturing efficiency is improved.

The lower surface of the upper mold 13 has a shape following the upper surface of the pavement material 1, and the bottom surface 4b of the groove 4 of the pavement material 1 is formed.
The convex portion 13a corresponding to is gently curved in a convex shape. When this convex portion 13a is pressed against the cemented concrete 12 with superhardness, the cemented concrete 12 moves quickly along the convex portion 13a and is filled in the recess 13b.
In this way, even if the material has poor fluidity, the material can be satisfactorily rotated to every corner in the mold and sufficiently compacted.

[0021]

As described above, according to the method of manufacturing a pavement material of the present invention, the pavement material can be manufactured very efficiently by the immediate demolding.
