Description

[Detailed description of the invention] This invention relates to decorative blocks for construction, and was devised to create an artificial decorative block that resembles natural Oya stone.

Some of the decorative blocks of conventional products are sold as Oya blocks even though they do not have the crater-like groove pattern that is unique to natural Oya stones.

The product of this invention creates a crater-shaped groove pattern similar to Oya stone, and at the same time, the inner surface of the groove pattern has a
Similar to Oya stone, it was devised to create a pattern with different colors from the block part.

To explain this in terms of drawings, first, we mix cement and a pigment similar to the color of the grooved inner surface of Oya stone (not necessarily a single color), and then turn Styrofoam into powder particles. Sprinkle it on the surface of the object and let it dry.

On the other hand, a block material is made by suitably mixing pigments similar to Oya stone, and this is mixed well with the above-mentioned styrene, coated with cement and pigment, and dried. After applying pressure and taking it out from the mold and drying it properly, the front part 4 and the rear part 5 of the block are sanded off smoothly with sanding paper so that the styrofoam surface is exposed.

Next, when first-class petroleum thinner is applied to this surface to dissolve and remove the styrofoam portions that are exposed on the surface, a concave groove pattern 2 as shown in Figures 1 and 2 will appear on the surface. It's coming.

On the other hand, on the inner surface of the groove pattern 2, the pigment sprinkled on the styrene surface with cement becomes a colored pattern 3 and appears on the inner surface of the groove pattern.

In other words, the makeup block 1 is mixed with a pigment similar to Oya stone, so it becomes Block 1 similar to Oya stone, and the styrene part washed away with thinner is
A crater-shaped concave groove pattern 2 similar to that of Oya stone appeared, and a color pattern 3 similar to Oya stone was created on the inner surface of the concave groove.

Furthermore, by appropriately mixing the pigments mixed into the block material and the pigments sprinkled on the styrene parts, it is possible to easily create decorative blocks that are slightly different from Oya stone.

In this way, this invention has become a useful invention that allows decorative blocks similar to Oya stone, as well as ones with a slightly different taste, to be manufactured, easily, and inexpensively.
