A second stone material 13 such as a natural stone such as a cobblestone or a crushed stone, or an artificial cobblestone or a crushed stone is disposed between the first and the first stone 11, and as shown in FIG. Sand between 14
(Third step). Further, after the completion of the third step, as shown in FIG. 6, by spraying an appropriate amount of water from above, the sand 14 adhering to the upper surfaces of the stone 11 and the second stone 13 can be washed off. Then, the sand 14 is compacted to form a second step forming sand layer 14A around the second stone stone 13 (fourth step).

After curing in the state shown in FIG. 7, after the concrete 15 is hardened, the semi-finished product 16 is taken out from the mold and turned upside down (inverted). During this demolding, sand 12,14
Most of the natural fall from the surface of the semi-finished product 16, but between the stone materials 11, 11 and 13, 13, or the stone materials 11,
Since the sands 12 and 14 still adhere to the surface of 13,
Water is applied to this surface to wash off the sand 12 and 14 (6th
Process), a finished product 17 as shown in FIGS. 8 and 9 is obtained.

The first and second stone materials 13 are fixed in an exposed state, and the two stone materials 11 and 13 are still on the surface 17A of the block 17, respectively.
The projecting height from the to the top will be different.
That is, as shown in FIG. 8, the protruding height H1 of the stone material 11 from the block surface 17A is larger than the protruding height H2 of the second stone material 13. Therefore, surface 1 of block 17
7A includes a stone material 11 having two types of protrusion heights,
As a result, 13 can be formed, and a concrete decorative block having an appearance like natural stone can be obtained.

る。In the above embodiment, the step forming sand layer has two layers (12A, 14A).
It is also possible to form three layers or four layers by selecting the sizes of 1 and 13, and in this case, the stone material having projections and depressions of three kinds is mounted on the surface 17A of the block 17. As a result, it is possible to obtain a concrete decorative block having a more natural stone-like appearance.

た諸効果がある。As described above, the method for manufacturing a concrete decorative block according to the present invention includes, as described above, the first step of arranging natural stone or the like on the bottom of the mold and inserting sand between the natural stone or the like. A second step of spraying to wash away the sand adhering to the surface of the natural stone, and then compacting the sand to form a step-forming sand layer between the natural stones, etc., further on the step-forming sand layer A third step of arranging a second natural stone or the like and inserting sand between the natural stones or the like, and spraying water from above to compact the sand to form a second step forming sand layer between the second natural stones or the like. A fourth step of forming a mold, a fifth step of putting concrete into the mold, and a sixth step of removing the sand by applying mold and water after hardening the concrete. From the above, it is arranged with natural stones exposed on the surface of the block. However, since the protruding heights of these natural stones from the block surface are fixed in a non-uniform manner, it is possible to obtain concrete blocks that have the same appearance as natural stones. In addition, there are various effects that the equipment and the manufacturing process are simple and can be provided at a low price.
