Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grating, which is generally called a water drop lid and is used as a lid for a gutter or a basin, and has a design on its surface.

[0002]

2. Description of the Related Art Grating is a method in which a water drop space is defined by a lattice-shaped frame material, and rain water is caused to flow from the water drop space into a gutter or a sump. In recent years, a design of the grating surface has been proposed for the purpose of improving the landscape.

[0003] Conventionally, as a design-provided grating having a design on the surface, a design plate having the design on the surface is attached to the upper surface of the grating body.

Further, the applicant of the present invention, as prior art,
We have already proposed a designed grating in which a part of the flooded space is filled with concrete and the surface of the filled concrete is designed.

[0005]

However, in the above-described conventional grating with a design, since the design plate is made of iron to prevent damage, when it is attached to the grating main body made of an iron frame, The rattling causes abnormal noise, which causes noise.
Further, since it is made of iron, there is a problem that rust is generated, and the design is soiled by the rust, which adversely affects the landscape.

Further, in the above-mentioned prior art, the filling concrete was formed by filling the concrete over the entire depth from the upper surface to the lower surface of the water drop space. For this reason, the amount of concrete increases, which is disadvantageous in terms of cost, and also causes the problem that the weight becomes heavy.

The present invention has been made in order to solve the above-mentioned conventional problems. The surface can be designed without noise and rust, and compared with the prior art. It is an object to provide a grating with a lightweight design that is cost-effective.

[0008]

In order to solve the above-mentioned problems, the designed grating of the present invention comprises a grating main body in which a large number of water drop spaces are defined by a grid-like frame member. Part of the water drop space is filled with concrete, the surface of the filled concrete is designed, the filled concrete is formed from the upper surface of the water drop space to an intermediate depth, and a non-filled space is formed below the filled concrete. Are formed.

[0009]

[Function] The grating main body has a large number of water drop spaces defined by the grid-like frame material, and the surface of the grid-like frame material has a narrow width when a design is to be made on the surface thereof. Design cannot be applied to the waterfall space. For this reason, it becomes necessary to fill the flood space and design it.

In the present invention, attention is paid to filling the water drop space, and since the water drop space is filled with concrete and the surface of the filled concrete is designed, the surface of the water drop space is designed without using a conventional design panel. It is possible to obtain a designed grating with a design.

Further, since a part of the water drop space is filled with concrete, it is possible to secure the inflow of rainwater, which is the original purpose of the grating, by the water drop space not filled with concrete.

Further, since the filled concrete is formed from the upper surface of the water drop space to a midway depth and the non-filled space is formed below the filled concrete, the amount of concrete can be reduced and the cost is reduced. It ’s an advantage,
Become lightweight.

A total of 60 rows, 12 rows in a row, are formed. still,
This grating body 1 is made of iron and has a surface plated with zinc.

Part of the water drop space 10 is filled with concrete, and a design 3 is applied to the surface of the filled concrete 2.

In this case, in two places of the grating body 1, the filled concrete 2 is formed so as to be adjacent in the vertical and horizontal directions in all five rows in the vertical direction and three rows in the horizontal direction.
It should be noted that the adjacent filled concretes 2 and 2 are arranged so that the filled concretes 2 and 2 are overriding the upper surface of the grid-shaped frame member 11 and are continuous with each other
A slight raised portion 20 is formed.

The filled concrete 2 is formed from the upper surface of the water drop space 10 to a depth halfway, and a non-filled space 12 is formed below the filled concrete 2.

As a method for filling the water drop space 10 with concrete, for example, the grating body 1 is placed on a flat plate to close the bottom opening of the water drop space 10 and the filled concrete 2 is formed in this state. Granules such as sand, granular glass, beads, etc. are put into the space 10 to an intermediate depth, and concrete is filled from above. As a result, the non-filling space 12 is formed in the portion containing the granular material. Further, the upper surface of the filled concrete 2 is preferably troweled.

Further, in the design 3 of the embodiment, the entire surface of the continuous filled concrete 2 is color-painted with one color as the base color 31, and on this base color 31, the flower pattern 32 is painted in several colors. It is colored and painted.

As the paint used for this coating, it is preferable to use a paint having excellent wear resistance in order to prevent the design 3 from being worn by a tire or the like. As the coating having excellent wear resistance, for example, aggregate-containing coating is used. This aggregate-containing paint is, for example, a mixture of cement with ceramic fine aggregate or natural stone fine aggregate (garnet, diamond, quack, etc.) mixed with acrylic resin or methyl methacrylate resin. Is used. or,
An inorganic pigment that does not change color is used as the pigment. The coating method may be spraying or brush coating.

As described above, in the designed grating of this embodiment, since the water drop space 10 is filled with concrete and the surface of the filled concrete 2 is provided with the design 3, the design 3 is applied to the surface without using the design panel. It is possible to obtain a grating with a design.

Further, since the filled concrete 2 is formed in a part of the water drop space 10, it is possible to secure the inflow of rainwater, which is the original purpose of the grating, from the water drop space 10 in which the filled concrete 2 is not formed. .

Further, since the filled concrete 2 is formed from the upper surface of the water drop space 10 to an intermediate depth, and the non-filled space 12 is formed below the filled concrete 2,
The amount of concrete can be reduced as compared with the case where filling concrete is formed in the entire water drop space, which is advantageous in terms of cost and weight.

Next, FIG. 3 is a plan view showing a grating with a design of the second embodiment, and FIG. 4 is a sectional view taken along line AA of FIG.

The grating with this design has a total of 50 rows of 5 rows in the vertical direction and 10 rows in the horizontal direction by the grid-like frame material 11.

As for the filled concrete 2 formed by filling the water drop space 10 with concrete, two continuous pieces on the left and right are arranged in a checkered pattern, and the design 3 is applied to the surface of the filled concrete 2. There is.

The design 3 in this case is one in which the surface of each filled concrete 2 is only colored with one color, and the design is aimed at the fun of the arrangement pattern in which the colored surface is arranged in a checkered pattern. There is.

Further, the filling concrete 2 is formed from the upper surface of the water drop space 10 to an intermediate depth, and the non-filling space 12 is formed below the filling concrete 2 as compared with the first embodiment. It is the same.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to the embodiments.

For example, of the water drop spaces, which water drop space is to be filled with concrete is determined in relation to the design, and if the filled concrete is continuous in the vertical and horizontal directions as in the first embodiment. It is possible to form a large design area, and as in the second embodiment,
By arranging the filled concrete in a dotted pattern, it is possible to express a design using the arrangement pattern as an element.

The design does not necessarily require colors, and may be a pattern expressed by engraving on the concrete surface. The point is that colors, patterns (including characters), and combinations of these may be used.

Further, lightweight concrete and resin mortar are included in the concrete to be filled in the water drop space.

[0033]

As described above, in the designed grating of the present invention, since the water drop space is filled with concrete and the surface of the filled concrete is designed, the conventional design panel is used. It is possible to obtain a designed grating with a design on the surface without using it. Therefore, it is possible to prevent the generation of noise and prevent the design from being damaged by rust.

Further, since a part of the water drop space is filled with concrete, it is possible to secure the inflow of rainwater, which is the original purpose of the grating, by the water drop space not filled with concrete.

Further, since the filled concrete is formed from the upper surface of the water drop space to a depth in the middle, and the non-filled space is formed below this filled concrete, compared to the case where the filled concrete is formed in the entire water drop space. The amount of concrete can be reduced, which is advantageous in terms of cost and weight.
