Description

[Detailed description of the invention]

[0001]

The present invention relates to a concrete surface which is exposed as a road surface (including a vehicle such as a vehicle or a road where people pass, a parking lot, a plaza, a floor of a building, etc.)
It relates to concrete products designed by painting.

[0002]

2. Description of the Related Art Conventionally, there is no concrete product designed by painting a concrete surface exposed as a road surface on the ground in an installed state.

[0003] Conventionally, it has been known that a design by painting is applied to a road surface by on-site construction instead of a concrete product. In the construction, a pattern forming the joint groove is attached to the road surface, a paint is applied to a predetermined thickness from above, and after the paint is dried, the pattern is peeled off. As a result, a design surface partitioned into a plurality of painted portions by the joint grooves is formed on the road surface.

[0004]

In the design surface formed in this way, since a plurality of painted portions are defined by joint grooves, when rain falls, rainwater accumulates in the joint grooves. . If the rainwater is left standing, slipping or splashing occurs, and especially in cold weather, a slipping accident due to freezing occurs. To prevent this, it is necessary to drain the rainwater from the joint groove.

An object of the present invention is to provide a design concrete product in which rainwater accumulated in joint grooves can be drained naturally from the above viewpoint.

[0006]

In order to solve the above-mentioned problems, the design concrete product of the present invention has a design surface formed on a concrete surface which is exposed as a road surface on the ground in an installed state. The groove is divided into a plurality of painted portions, and the painted portion is formed to a predetermined thickness by applying an aggregate-containing paint having a predetermined color, and at least a part of the joint groove communicates with the outside of the design surface. It is formed in the drainage part.

[0007]

First, a method of manufacturing the design concrete product of the present invention will be described. Of the concrete surface of the concrete product formed in a predetermined manner, a mold (regardless of paper, metal, synthetic resin, etc.) for forming joint grooves is placed on a concrete surface which is exposed as a road surface on the ground in an installed state, From there, an aggregate-containing paint having a predetermined color is applied. Then, after the coating is dried, if the mold is removed, the design surface divided into a plurality of coating portions by the joint groove is formed on the concrete surface.

At the time of construction, the design concrete product is installed so that the concrete surface serving as the design surface is exposed as a road surface on the ground in the installed state.

In this design concrete product, since the concrete surface of the concrete product itself is formed on the design surface, if the design concrete product is constructed, the design surface can be constructed simultaneously on the road surface. Therefore, there is no need to construct the design surface on site.

[0010] An aggregate-containing paint is used as a paint for the painted portion. This aggregate-containing paint is a mixture of an aggregate and a synthetic resin liquid, and the paint itself has a rough surface due to the aggregate, and since the paint is applied, the surface is roughened in the applied state. Therefore, the roughened portion can provide the coating portion with an anti-slip function.

Further, at least a part of the joint groove is formed in a drain portion communicating with the outside of the design surface. Therefore, even if rainwater accumulates in the joint groove due to rainfall, the rainwater is naturally drained to the outside of the design surface from the drainage portion, and slip and water splash due to the accumulation of rainwater in the joint groove can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing the design concrete product of the first embodiment.

In the first embodiment, the gutter block 1 and the concrete lids 2 and 2 used for the gutter block 1 are used as the main body of the design concrete product.

The side groove block 1 includes left and right side walls 1.
The upper ends of both ends are connected by beams 12, 12, so that an opening 13 is formed at the center of the upper surface, and a concrete block having an open bottom surface is formed.

As shown in FIG. 2, the gutter block 1 is constructed such that its upper surface is exposed on the ground G as a road surface in the installed state, and the entire upper surface is formed on the design surface 14. Have been.

The design surface 14 is divided into a plurality of painted portions 14b by joint grooves 14a. In this embodiment, the design is such that the rectangular painted portions 14b are alternately arranged in a staggered manner while maintaining the intervals of the joint grooves 14a.

The joint groove 14a is provided at the edge 1 of the opening 13.
3a and the outer edge 15 are formed.
a and the end of the joint groove 14a interrupted by the outer peripheral edge 15 becomes a drainage portion 16 communicating with the outside of the design surface. As a result, the rainwater collected in the joint groove 14a passes through the joint groove 14a and passes through the rim 13a and the outer peripheral edge 15a.
Flows down from the draining part 16.

The coating portion 14b is formed by applying an aggregate-containing paint having a predetermined color (brick color in the embodiment) to a predetermined thickness (2 mm or less in the embodiment) by spray coating using a spray device. ing.

The above-mentioned aggregate-containing paint may be, for example, a fine aggregate obtained by mixing a ceramic fine aggregate or a natural stone fine aggregate (garnet) with white cement, an acrylic resin solution or a methyl methacrylate resin solution. Is used, and there is no discoloration because it is colored with an inorganic pigment.

Next, a method of manufacturing the design surface 14 will be described. In the concrete surface of the gutter block 1 formed in a predetermined manner, a mold for forming the joint groove 14a on the upper surface which is exposed as a road surface on the ground G in the installed state (in the embodiment, the back surface is formed as a peelable adhesive surface. , A flexible thermoplastic resin mold). Next, an aggregate-containing paint is spray-coated from above with a spray device.
Then, after the coating is dried, if the mold is removed, as shown in FIG.
A design surface 14 defined by 4a is formed on the upper surface.

When the gutter block 1 having the design surface 14 formed on the upper surface is constructed, as shown in FIG. 2, the upper surface serving as the design surface 14 is exposed as a road surface on the ground G in the installed state. And installed according to the usual construction method.

As described above, the side groove block 1 of the embodiment is described.
Since the upper surface itself is formed on the design surface 14, if the gutter block 1 is constructed, the design surface 14 can be constructed on the road surface at the same time.
Accordingly, there is no need to construct the design surface 14 on site.

An aggregate-containing paint is used as a paint for the coating portion 14b, and the aggregate-containing paint is applied to a predetermined thickness by spray coating. This aggregate-containing paint is a mixture of fine aggregate in a synthetic resin liquid, and the paint itself has a rough surface due to the fine aggregate, and is applied by spraying. Sticking occurs. Accordingly, the roughening can provide the coating portion 14b with an anti-slip function.

Further, in the embodiment, the coating thickness of the coating portion 14b is as thin as 2 mm or less. This is because the thinner the coating thickness, the easier the coating work and the more advantageous the cost. . Further, since the aggregate-containing paint has excellent wear resistance, peeling due to abrasion of the paint can be prevented even when the paint thickness is reduced to 2 mm or less. In addition, when the coating thickness is large, the corners of the coated portion are easily chipped, but when the coating thickness is reduced to 2 mm or less, chipping of the coated portion can be prevented.

Further, the end of the joint groove 14a is
The drainage part 16 communicating with the outside of 4 is formed. Therefore, even if rainwater accumulates in the joint groove 14a due to rainfall, the rainwater is naturally drained from the drainage portion 16 to the outside of the design surface 14, thereby preventing slip and water splash due to the accumulation of rainwater in the joint groove 14a. Can be.

Next, the concrete lid 2 is installed so as to be fitted into the opening 13 of the gutter block 1, and in this installation state, the upper surface is uniform with the upper surface of the gutter block 1. It is exposed as a road surface on the ground G.

Then, the entire surface of the upper surface is formed by the joint groove 24a.
Design surface 2 divided into a plurality of painted parts 24b by

Is formed. As a result, the rainwater collected in the joint groove 24a flows out of the drainage portion 26 through the joint groove 24a as a path.

Although the embodiment of the present invention has been described with reference to the drawings, the specific structure of the present invention is not limited to the above-described embodiment. The main body is a concrete product, such as a main body with a U-shaped gutter block and a design surface formed on the upper surface of the side wall, and a main body with a box-shaped gutter block (conduit) and a design surface formed on the upper surface. It is sufficient that the concrete surface exposed as a road surface on the ground in the state is formed on the design surface.

Also, the design of the design surface may be a single or a combination of a pattern such as a round or a square, a straight line or a curve, a picture pattern, or the like, and the color is not particularly limited. Also, as a coating means,
Not only spray coating but also brush coating may be used.

[0034]

As described above, in the design concrete product of the present invention, since the design surface is formed on the concrete product itself, the inconvenience associated with forming the design surface by on-site construction can be eliminated.

In addition, since an aggregate-containing paint is used as the paint and the paint is applied to a predetermined thickness, the surface may be roughened in the coated state, and the roughened surface may have a non-slip effect on the painted portion. In addition, since the aggregate-containing paint is excellent in abrasion resistance, peeling due to abrasion of the paint can be prevented.

Further, since at least a part of the joint groove is formed in a drainage portion communicating with the outside of the design surface, even if rainwater accumulates in the joint groove due to rainfall, the rainwater flows from the drainage portion to the design surface. Drains naturally to the outside. Therefore, an effect is obtained in which slip and water splash due to accumulation of rainwater in joint grooves can be prevented.
