Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imitation concrete stone block which looks like a stone (for example, goroite).

[0002]

2. Description of the Related Art Conventionally, stones such as goroite used as exterior stepping stones and other decorative members are natural stones, and there is no artificial stone made of concrete.

[0003]

As described above, stones conventionally used as stepping stones and decorative members are all natural stones, and it is preferable to collect them from the viewpoint of maintaining a natural environment. Is hard to say.

An object of the present invention is to provide an imitation stone block artificially manufactured using concrete from the viewpoint of maintaining such a natural environment.

[0005]

In order to solve the above-mentioned problems, an imitation stone block according to the present invention (claim 1) comprises a stone-shaped stone block formed of concrete, Is formed on a polished surface obtained by polishing a concrete ground.

[0006] As a polishing process for forming on a polished surface, a concrete ground is polished using a rotating grindstone or a rotating wire brush. The polished surface becomes glossy at the same time as the polished portion becomes black (dark gray) as compared with the portion where the concrete ground remains, and becomes a so-called black glowing state. Therefore, even though it is concrete, it is possible to express the texture of natural stone, and it is possible to make the appearance look as if it is natural stone.

In this case, there is a mode in which a water repellent or a transparent paint is applied to the polished surface (claim 2). Since the polished surface has a blackish gloss, it is desirable to maintain this gloss. Therefore, the gloss of the polished surface can be maintained by applying a water repellent or a fungicide to the polished surface to prevent the surface from being stained, or by applying a transparent paint or the like.

In the imitation stone block of the present invention (claim 3), a plurality of stone blocks formed in a stone shape are formed of concrete, and the plurality of stone blocks are connected by a connecting member. The surface of at least one of the plurality of stone blocks is formed on a polished surface obtained by polishing a concrete ground. In this case, the surface of all the stone blocks may be formed on the polished surface, or the surface of one part (for example, only one) of the stone blocks may be formed on the polished surface. When the surface of a part of the stone block is formed on the polished surface, the surface of the other stone block not formed on the polished surface may remain as the concrete ground, or a water repellent or a waterproofing agent may be applied to the concrete ground. It may be formed on the stain suppression surface coated with a mold agent,
Arbitrary, such as forming on a colored surface coated with paint or pigment, or formed on a frayed surface that has been frayed. This imitation stone block is formed by connecting a plurality of stone blocks with a connecting member. Therefore, it can be provided as one imitation stone block in a state where a plurality of stone blocks are gathered. In this imitation stone block, there is a mode in which a water repellent or a transparent paint is applied to the polished surface (claim 4). In this case, a water-repellent agent or the like may be applied to all the polished surfaces, or a water-repellent agent or the like may be applied to some polished surfaces, and the other polished surfaces may not be coated with the water-repellent agent. The polished surface may be used. As described above, when a polished surface is coated with a water repellent or the like, and a non-coated surface is provided, a difference occurs in the gloss, and a design utilizing the contrast of the gloss can be expressed.

In the imitation stone block of the present invention (claim 5), a stone block in which a plurality of stone-shaped parts formed in a stone shape are integrally connected is formed of concrete. The surface of the stone-shaped portion was formed on a polished surface obtained by polishing a concrete ground.

[0010] In this imitation stone block, the stone block has a plurality of stone portions integrally connected. Therefore, although it is one block, it can be provided as a state in which natural stone materials are gathered. For example, when this is used as a stepping stone for an exterior, it can be constructed as if the natural stones were gathered and spread. Further, in this imitation stone block, there is a mode in which a water repellent or a transparent paint is applied to the polished surface (claim 6). In this case, a water-repellent agent or the like may be applied to all the polished surfaces, or a water-repellent agent or the like may be applied to some polished surfaces, and the other polished surfaces may not be coated with the water-repellent agent. The polished surface may be used. In this way, a polished surface coated with a water repellent or the like,
If a material that is not applied is provided, a difference occurs in the gloss, and a design utilizing the contrast of the gloss can be expressed.

In the imitation stone block according to the present invention (claim 7), a stone block in which a plurality of stone-shaped parts formed in a stone shape are integrally connected is formed of concrete. The surface of a part of the stone portion is formed on a polished surface obtained by polishing the concrete surface, and the surface of at least one stone portion of the remaining stone portion is formed on the ground surface of the concrete surface. The configuration was adopted. As described above, when the surface of the stone-shaped portion of the stone-shaped block is a combination of the polished surface and the ground surface, a design expression utilizing the contrast due to the brightness difference between the polished black surface and the ground surface can be obtained. In addition, when a water repellent or a transparent paint is applied to the polished surface and the ground surface (claim 8), it is possible to maintain blackening of the polished surface and to prevent the ground surface from being stained. The lightness difference becomes clearer. In this case, a water repellent or the like may be applied to all the polished surfaces and all the ground surfaces, or a water repellent may be applied to some of the polished surfaces and some of the ground surfaces, and the other polished surfaces and The ground surface may be left as it is without applying a water repellent or the like. In this way, when a polished surface is coated with a water-repellent agent or the like and when it is not coated, a difference is generated in the gloss, and a design utilizing the contrast of the gloss can be expressed. At
A design expression utilizing contrast can be provided by the brightness difference between the ground surface where the concrete ground is stained and darkened and the ground surface where the stain is suppressed by a water repellent or the like. As time goes by, we can provide designs that are naturally soiled.
