Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a colored coating structure for a gutter block, a gutter lid, a basin block, etc. (hereinafter referred to as a concrete block) which is installed so that its surface appears on the road surface.

[0002]

2. Description of the Related Art In recent years, in order to improve the scenery of roads, it has been found that many concrete blocks are installed on the road surface with a colored coating.

In this case, in the conventional colored coating structure, a concrete block is colored and a coating is formed on the colored coated surface with a transparent top coat.
Therefore, this coating can protect the colored coated surface.

[0004]

However, when a coating is formed on the colored coated surface with a transparent topcoat as in the conventional colored coating structure, the surface becomes smooth due to this coating, which makes it slippery. Especially when the road surface is wet due to rain, a person or a vehicle passing over the concrete block may slip, causing a fall or an accident.

The present invention has been made to solve the above-mentioned problems, and it is possible to prevent slipping while maintaining the protection of a colored coated surface by forming a film on the colored coated surface. It is an object of the present invention to provide a colored coating structure for a concrete block.

[0006]

In order to solve the above problems, a colored coating structure for a concrete block installed on a road surface according to the present invention has a structure in which the surface of the concrete block installed on the road surface is colored with an aggregate-containing paint. In a colored coating structure of a concrete block which is coated and has a coating formed on the colored coated surface with a transparent top coat, a slip preventing projection formed integrally with the concrete block is formed on the surface of the concrete block. The colored coating surface and the coating film are formed on the surface of the concrete block which is provided in a protruding manner and on which the anti-slip projections are formed.

[0007]

In the colored coating structure of the present invention, the colored coating surface is formed of the aggregate-containing paint. This aggregate-containing paint is, for example, a mixture of cement, natural stone fine aggregate, and acrylic resin, and has excellent abrasion resistance, so even if the coating may be worn away by people or vehicles, The painted surface does not wear out. Therefore, at the time of repair, it is not necessary to modify the colored coated surface, and it is sufficient to repair only the coating.

Further, since the coating is formed on the colored coated surface, this coating can protect the colored coated surface.

Further, since the anti-slip projections are formed on the surface of the concrete block installed on the road surface, the anti-slip projections increase the frictional force. Therefore,
The problem of slipperiness due to the formation of the coating can be solved by the non-slip projections.

Further, since the non-slip projections are formed integrally with the concrete block at the same time when the concrete block is manufactured, the projections are to be projected by adhesion or the like in post-processing after the concrete block is manufactured. In comparison, manufacturing becomes easier.
