Abstract

PURPOSE:To make it possible to manufacture a patterned iron cover at a low cost, and what is more, with ease by mounting a paper pattern which installs countless dents on the surface of the cover and provides a cut through holes for the formation of patterns and letters on the surface of the iron cover and filling up the dents with colored resin paint. CONSTITUTION:Countless dents 4 are made in the whole surface 2. A paper pattern having cut through holes is joined with the surface 2 of an iron cover 1 on which the dents 4 are formed. The dents are filled up and coated with colored resin paint. During this operation, patterns or letters, which depict landscapes, flowers and trees, birds and animals, for example, are formed on the cut through holes. A different paper pattern is used for each color and pained. It is also arranged that the other areas of the iron cover may be painted in addition to the dents 4 of the iron cover 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to an iron lid provided on the above-ground opening of an underground structure, and more particularly to an iron lid with a pattern such as landscapes, flowers, birds and beasts, characters, etc. Is.

[0002]

2. Description of the Related Art Conventionally, the surface of an iron lid for an underground structure has been formed by casting various geometrical uneven patterns in order to prevent slippage.
Scenery designated by the municipality on the iron cover of the sewer manhole,
Patterns such as flowers and birds and beasts, and fire engine and fire engineer patterns were cast on the iron lid of the water supply valve casing with fire hydrants.
Further, products have been used in which recesses are filled with a colored resin paint to form a beautiful pattern, and characters such as fire hydrants can be seen at a glance with the colored resin paint.

[0003]

As described in the prior art, the iron lid provided on the above-ground opening of the underground structure has a pattern or characters such as landscapes, flowers, birds and beasts attached to each municipality. However, iron lids are mainly made of cast iron, and are cast using a sand mold or styrofoam mold that is molded using a mold. Changing the mold requires more molds, which inevitably increases the cost, and problems such as increase in the types of molds and difficulty in storage and management have come to be found in the foundry.

The present invention has been made in view of the problems that have recently arisen due to the demands of the market, and an object of the present invention is to easily manufacture a small-sized patterned iron lid inexpensively and easily. To provide.

[0005]

[Means for Solving the Problems] In order to achieve the above object, as a result of various studies, when casting an iron lid with cast iron,
This can be solved by forming innumerable depressions on the entire surface of the iron lid and filling the depressions with a colored resin paint so as to draw a pattern.

That is, when the colored resin paint is filled in the depressions, it is sufficient to use a pattern paper in which the colored portion forming the pattern is cut out. It is only necessary to prepare a paper pattern beforehand so that the iron lid without a pattern is prepared by a mold that forms a recess on the surface according to the disk shape, square shape, other necessary shape and dimensions used for casting the iron lid. In addition, it is possible to solve the problem by preparing a pattern in which a pattern for each customer is punched out. As the colored resin coating, it is desirable to use an epoxy resin coating excellent in abrasion resistance, but it is not particularly limited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in the drawings. According to the present invention, first, as shown in FIGS. 1 and 2, an iron lid (1) cast from cast iron or the like is formed with innumerable dents (4) over the entire surface (2) of the iron lid (1). Prepare the thing, the shape and size of the depression (4) is not particularly specified, the upper surface opening of the depression (4) may be circular, triangular, rectangular, polygonal, and the aperture is The smallest that can be formed in a mold is desirable. The shape of the iron lid (1) is shown as a disk-shaped iron lid, but the shape is not limited to this, and is also applicable to a square iron lid or the like.

Next, as shown in FIG. 3, a cutout hole (7) in the shape of a pattern, characters, etc. of scenery, flowers, birds and beasts,
The pattern paper (6) having (8) and (9) is brought into close contact with the surface (2) of the iron lid (1) having the depression (4) formed on the surface (2) as shown in FIG. , Epoxy resin paint mixed with green pigment is cut out hole (7), pink epoxy resin paint is cut out hole (8)
Then, apply blue epoxy resin paint so that it fills the recesses (4) exposed in each of the cutout holes (9), remove the pattern (6), and cure the paint to obtain a patterned iron lid It is a thing.

The pattern (6) is made of paper, a plastic plate,
Cutouts (7), (8), (9) may be formed by cutting out or punching out the design using a metal plate, etc., and paint is applied using a different pattern (6) for each color. However, it may be filled in the recesses (4) of the iron lid (1) or may be coated so as to cover the boundary between the recesses (4) and the recesses (4). It should be noted that, as shown in FIG. 1, a rim (3) which does not form the depression (4) may be provided if necessary.

[0010]

As described above, according to the present invention, if an iron lid having a depression on the surface is prepared in advance, a pattern having a cutout hole prepared by punching out a pattern desired by a consumer is used. , It can be supplied immediately by filling the recess of the iron lid exposed in the cutout hole of the pattern with colored resin paint and forming a pattern,
Therefore, there is no need to prepare molds with different patterns and letters,
Since it is only necessary to prepare the pattern paper, it is possible to promptly and inexpensively provide the iron cover with a small lot of the pattern to the customer. Further, the depressions on the surface not filled with the paint can be expected to have an effect of preventing slip. Further, not only the iron cover but also a groove cover having a patterned plate formed in the central portion by a grating groove cover is useful.
