Abstract

(57) [Summary] [Problem] The present invention relates to a concrete groove having a slope.
It is an object of the present invention to be able to lay grating that is drainable and easy to open and close. In order to achieve the above object, a grating is attached to a raised material having a slope, and a cover plate having projections formed in the shape of a grating and a V-shape is provided on the grating. It is characterized by eliminating the step at the boundary between the grating attached and laid and the sidewalk.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a steel grating used for a gutter cover of a road or the like, and is a V-shaped sloped grating in which a grating is attached on a sloped raising material.

[0002]

[Prior art]

 Conventionally, the thickness of the lid on the side of the sidewalk and the sidewalk is slightly larger on the side of the sidewalk, and the boundary between the sidewalk and the slope is smooth. A shape-shaped concrete lid product was used.

[0003] In the case of a concrete lid product, the opening dimensions and the quantity for drainage are limited in order to satisfy the strength surface. As a result, sufficient drainage was not possible, and it was easy to get wet when it rained.

Further, since the concrete lid is heavy, the lid cannot be easily opened and closed, and it is difficult to clean even if dirt, dust, and the like accumulate in the grooves.

[0005] Since there is no unevenness on the upper surface of the concrete lid, the concrete lid has no anti-slip function and is easily slipped in a wet state.

The shape of the concrete product could be freely processed like a V-shape. However, the steel grating, which is drainable and easy to open and close, has only a flat plate shape, and could not be laid in such concrete grooves.

[0007]

[Problems to be solved by the invention]

 The present invention is intended to solve the problem of such a conventional structure, and to lay a drainage drainable grating that can be easily opened and closed in a sloped concrete groove. It is intended for that purpose.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned purpose, a gradient is provided in the grating to eliminate the step at the boundary between the laid grating and the sidewalk. The second means for solving the problem is to attach a grating to the raised material 3 provided with a gradient, and to attach a cover plate 4 with a projection formed in the grating and a V-shape to a reinforcing rib 5 provided on the grating. The present invention is a V-shaped gradient grating having the above-described configuration.

[0009]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the grating is provided with a gradient. The grating may have non-slip projections.

As shown in FIG. 3, a raised material 3 having a gradient according to the surrounding gradient is provided, and a cover plate 4 for forming a grating and a V-shape is attached on the raised material 3. The grating and cover plate may have non-slip projections. Reinforcing ribs 5 are inserted into the lower surface of the cover plate 4 in preparation for exceeding the design load. The cover plate may be made of an L-shaped material such as 9 or a tapered material such as 10.

[0012] This makes it possible to lay the grating with drainability and easy opening and closing, and eliminate the step at the boundary between the grating and the sidewalk.

[0013]

[Effect of the invention]

 According to the present invention, it is possible to make use of the drainage characteristic of the conventional grating as it is, and eliminate a step with an adjacent sidewalk. In addition, since it is lighter in weight than conventional concrete lid products, it can be easily opened and closed, and operations such as cleaning can be easily performed.
