Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a concrete gutter cover that closes the opening of a gutter installed along the shoulder of a road, and more specifically, to a concrete gutter cover that is installed on the concrete gutter cover. , relates to a drainage board that allows rainwater on the road to fall into a side yard.

[Prior art]

Drain plates for concrete gutter covers are sometimes made of ceramic material for strength, and a plurality of through holes are drilled at appropriate locations on the flat plate-shaped drain plate.

By the way, in conventional ceramic drain plates, the through holes are formed with the same dimensions from the top surface to the bottom surface.

Furthermore, the upper surface of the drain plate was formed to be rough due to the characteristics of the material.

[Problem that the invention attempts to solve]

In the case of the conventional drainage board mentioned above, the hole diameter (or hole width) of the through hole was the same from the top to the bottom, so there was a problem that the dirt and pebbles that flowed in with rainwater easily clogged the board. It was hot.

Furthermore, since the upper surface of the conventional drain plate is formed with a rough surface, there is a problem that the drain plate easily becomes dirty due to the adhesion of mud and the like.

The technical problem to be solved by the present invention is to provide a drain plate for a concrete gutter cover that eliminates the above-mentioned problems.

[Technical measures taken to solve the technical problems of the invention]

The technical means taken to solve the technical problem was to form a plurality of through holes at appropriate locations in the drain plate body, which is made entirely of ceramic material, and to connect the through holes to the upper surface of the drain plate body. It has a shape that widens from the top to the bottom, and the dimensional difference between the top and bottom ends is 2 to 2.
4mm, and the top surface of the drain plate body is
The colored layer is coated with a coating using metal oxide pigments to give it a smooth finish.

As a result, clogging of the through holes with dirt and pebbles is extremely reduced, and the upper surface of the drain plate is smooth and has a good appearance, and cleaning can be easily performed.

〔Example〕

To explain the present invention with reference to the embodiments shown in the drawings, Fig. 1 is a perspective view of a gutter cover using the present invention, Fig. 2 is a sectional view taken along line A-A of the previous figure, and Fig. 3 is an enlarged perspective view of the present invention. , FIG. 4 is a sectional view taken along the line B--B of the previous figure.

Reference numeral 1 in the figure is a concrete gutter cover, and a drainage plate 2 made of a ceramic material is incorporated into a part of the gutter cover so as to be placed on a stepped portion 3 of the gutter cover.

A plurality of through holes 4 are bored at appropriate locations on the drain plate 2. The cross-sectional shape of the through-hole 4 is appropriately formed in a circular, oval, quadrangular, or similar shape, and the number of through-holes is approximately 2 to 6. In the example of the drawing, the length is 5 cm, the width is 15 cm, and the height is 2.5 cm.
Five approximately elliptical through holes 4 with a vertical dimension of 2.5 cm and a horizontal dimension of 1.5 cm are formed in a drain plate 2 of 1.5 cm in diameter.

Further, the through hole 4 is formed in a shape that widens from the upper surface to the lower surface of the drain plate, and in the example shown in the drawings, there is a dimensional difference of approximately 3 mm (usually about 2 to 4 mm) between the upper surface end and the lower surface end.

Next, on the top surface of the drain plate 2, silica sand, feldspar,
A colored layer 5 is formed by applying a top coat using pigments such as iron, cobalt, chromium, etc., and firing it together with a ceramic drainage plate. The colored layer 5 is finished in a desired color such as light blue, brown, green, yellow, or white, and is finished by firing, so it does not change color semi-permanently and can maintain its beautiful color for a long period of time.

[Effect of idea]

In this invention, the through-hole is formed in a shape that widens from the top surface to the bottom surface of the drain plate, so that any dirt or pebbles that pass through the top end of the through-hole will surely pass downward without becoming clogged within the through-hole. There is an effect that can be achieved.

Furthermore, since the upper surface of the present invention is formed with a colored layer, it becomes a colorful product that does not change color semi-permanently, improving its commercial value, and since it is a smooth surface, dirt does not easily adhere to it.

Claims (1)

[Scope of utility model registration request] A plurality of through holes are formed at appropriate locations in the drain plate main body, which is integrally formed entirely of ceramic material, and the through holes are flared from the upper surface to the lower surface of the drain plate main body, and the upper surface The difference in dimension between the edge and the bottom edge is 2 to 4 mm, and the top surface of the drain plate body is painted with a finish using a metal oxide pigment to create a smooth surface. A drain plate for concrete gutter covers that is characterized by being formed in layers.
