[Industrial applications]

 The present invention is a concrete designed by painting on a concrete surface exposed as a road surface (including vehicles such as automobiles and roads through which people pass, parking lots, plazas, and floor surfaces of buildings) when installed. Regarding the product.

[0002]

[Prior art]

 Conventionally, there are no concrete products that are designed by painting the concrete surface that is exposed as a road surface on the ground in the installed state.

Further, conventionally, it is known that not a concrete product but a design by painting is applied to a road surface by on-site construction. In the construction, the pattern paper that forms the joint groove was attached to the road surface, the coating material was applied to a predetermined thickness from above, and the pattern paper was peeled off after the coating material was dried. As a result, a design surface divided into a plurality of coating parts by the joint groove is formed on the road surface.

[0004]

[Problems to be solved by the device]

 On the design surface formed in this way, since a plurality of painted portions are demarcated by joint grooves, rainwater will collect in the joint grooves when it rains. If this rainwater is left in the pool, slips and water splashes will occur, and especially in cold weather, slip accidents due to freezing will occur.Therefore, in order to prevent this, it will be necessary to drain rainwater from the joint groove. .

In view of the above-mentioned viewpoints, the present invention has an object to provide a design concrete product capable of naturally draining rainwater accumulated in a joint groove.

[0006]

[Means for Solving the Problems] 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 exposed as a road surface on the ground in the installed state. It is divided into a plurality of coating parts by joint grooves, and this coating part is formed to a predetermined thickness by applying an aggregate-containing paint having a predetermined color, and at least a part of the joint grooves is a part of the design surface. It is formed in the drainage part communicating with the outside.

[0007]

[Action]

 First, a method of manufacturing the design concrete product of the present invention will be described. Of the concrete surface of the concrete product that has been molded in a prescribed manner, place a mold (it may be made of paper, metal, synthetic resin, etc.) that forms a joint groove on the concrete surface exposed as a road surface on the ground in the installed state, On top of that, an aggregate-containing paint having a predetermined color is applied. Then, after the coating is dried, the mold is removed, and the design surface divided into a plurality of coating portions by the joint groove is formed on the concrete surface.

Then, at the time of construction, this design concrete product is installed so that the concrete surface which is the design surface is exposed as a road surface on the ground in the installed state.

In this design concrete product, the concrete surface of the concrete product itself is formed on the design surface. Therefore, when this design concrete product is constructed, at the same time, the design surface can be constructed on the road surface. Therefore, there is no need to construct the design surface on site.

Further, an aggregate-containing paint is used as the paint for the painting part. This aggregate-containing paint is a mixture of an aggregate and a synthetic resin liquid, and the aggregate itself has a rough surface. Also, since this coating material is applied, the surface of the coating material becomes rough in the coated state. Therefore, with this rough surface, the painted portion can be made to have a non-slip effect.

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

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a 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 designed concrete product.

In the gutter block 1, the left and right side walls 11, 11 are connected at their upper ends at both ends by beams 12, 12, so that an opening 13 is formed at the center of the upper surface and the bottom is opened. It is formed on a concrete block.

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

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

The joint groove 14a is formed up to the rim 13a and the outer peripheral edge 15 of the opening portion 13, and the ends of the joint groove 14a interrupted by the rim 13a and the outer peripheral edge 15 are all outside the design surface. The drainage section 16 communicates with the. As a result, the rainwater collected in the joint groove 14a flows down from the drainage portion 16 with the mouth edge 13a and the outer peripheral edge 15 by way of the joint groove 14a.

The coating portion 14b is formed by applying an aggregate-containing coating material 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. Has been done.

As the aggregate-containing paint, for example, fine aggregate obtained by mixing white cement with ceramic fine aggregate or natural stone fine aggregate (garnet) is used as acrylic resin liquid or methyl methacrylate resin liquid. There is no discoloration because it is a mixture of the above and is colored with an inorganic pigment.

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

Therefore, the coating portion 14b can be made to have a non-slip action by this rough surface.

Further, in the embodiment, the coating thickness of the coating portion 14b is as thin as 2 mm or less. This means that if the coating thickness is reduced, the coating labor becomes simpler and the cost becomes advantageous. Become. Further, since the aggregate-containing paint has excellent wear resistance, even if the paint thickness is reduced to 2 mm or less, peeling due to abrasion of the paint can be prevented. Further, when the coating thickness is thick, the corners of the coated portion are likely to be chipped, but when the coating thickness is thinned to 2 mm or less, chipping of the coated portion can be prevented.

Further, the end of the joint groove 14 a is formed in the drainage portion 16 communicating with the outside of the design surface 14. Therefore, even if rainwater collects in the joint groove 14a due to rainfall, the rainwater is naturally drained from the drainage part 16 to the outside of the design surface 14, and slip and splash due to the rainwater collecting in the joint groove 14a are prevented. be able to.

Next, the concrete lid 2 is installed in a state of being fitted into the opening 13 of the gutter block 1. In the installed state, the upper surface is a uniform surface with the upper surface of the gutter block 1. Exposed on the ground G as a road surface.

The entire upper surface is formed as a design surface 24 divided into a plurality of coating portions 24b by joint grooves 24a. The design surface 24 is similarly formed by the same manufacturing method as the design surface 14 formed on the upper surface of the gutter block 1. The joint groove 24a is formed up to the outer peripheral edge 25, and all the ends of the joint groove 24a interrupted by the outer peripheral edge 25 become a drainage portion 26 communicating with the outside of the design surface 24. As a result, the rainwater collected in the joint groove 24a flows down from the drainage portion 26 with the outer peripheral edge 25 through the joint groove 24a as a passage.

It should be noted that the design surface 14 of the gutter block 1 and the design surface 24 of the concrete lid 2 may be continuous with both design surfaces 14 and 24 with uniformity, or may be formed in completely different designs. Alternatively, the colors of the two design surfaces 14 and 24 can be the same or different.

Next, FIGS. 3 and 4 are plan views showing the designed concrete products of the second and third embodiments. In the second and third embodiments, the concrete lid 2 is used as the main body of the design concrete product.

In the concrete lid 2 of the second embodiment shown in FIG. 3, a design surface 24 divided into a plurality of coating portions 24b by joint grooves 24a is formed on a part of the upper surface. Then, a part of the joint groove 24a is formed in the drainage portion 26 which communicates with the upper surface outside the design surface, whereby the rainwater collected in the joint groove 24a is drained through the joint groove 24a. It flows from the portion 26 to the outer upper surface.

In the concrete lid 2 of the third embodiment shown in FIG. 4, the design surface 24 divided into a plurality of coating portions 24b by the joint groove 24a is formed on a part of the upper surface, and a part of the joint groove 24a is formed. Further, a drainage hole penetrating the concrete lid 2 is formed as a drainage portion 26. As a result, the rainwater collected in the joint groove 24a flows out from the drainage portion 26 through the joint groove 24a as a passage.
