Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a gutter cover that covers the opening of a concrete gutter, etc.

(Prior Art) A conventional gutter cover has a grid-like main body made up of a large number of plate-shaped main members arranged in parallel at predetermined intervals, auxiliary members called twist bars that are orthogonal to these main members, and side members on both sides. is configured. Therefore, if a fine-mesh groove cover is required, the interval between the parallel plate-shaped main members should be narrowed, in other words,
The number of main members may be increased. however,
Increasing the number of main members means using a large amount of steel material, which not only increases cost but also increases the weight per unit area, which is disadvantageous for transportation and installation work.

Furthermore, since conventional gutter covers have a lattice shape, dirt and objects easily fall into the gutter through the gaps in the lattice, causing various problems.

(Problem to be solved by the invention) This invention was proposed in order to eliminate the drawbacks of the conventional groove cover as mentioned above, and its purpose is to improve the fine-grained groove cover of the main member. In particular, it is an object of the present invention to provide a gutter cover that is relatively economical and lightweight without increasing the number of main members. Another object of this invention is to provide a gutter cover with a structure that prevents dirt and objects from easily falling into the gutter through the gaps in the grate of the gutter cover.

(Means for Solving the Problems) That is, in order to achieve the above object, this invention provides a groove cover in which a large number of main members are arranged in parallel at predetermined intervals on a side member, in which the main members are plate-shaped. It is formed into a Y-shaped cross section by the main body and two groove plate parts formed on the upper part thereof, and the width of the upper part of the main member and the interval between the upper parts of adjacent main members are configured to be the same. The present invention relates to a groove lid characterized by:

(Example) An example will be described below according to the attached drawings.
Fig. 1 is an overall plan view of a gutter cover showing an embodiment of this invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Fig. 3 is a cutaway perspective view of a portion of the gutter cover shown in Fig. 1. FIG. 4 is a sectional view of the main member.

As shown in the figure, the groove cover 10 of this invention has a large number of main members 11 arranged in parallel at predetermined intervals, and is supported by an auxiliary member 16 called a twist bar that is perpendicular to the main member 11 and side members 17 on both sides. It is made up of a grid-like body.

The gutter cover 10 of this invention is characterized in that the main member 11 has the following configuration.

That is, as can be well understood from the sectional view in FIG. 2 and the enlarged views in FIGS. 3 and 4,
The main member 11 of this invention has a Y-shaped cross section, with two groove plate parts 12 integrally formed on the upper part of a plate-shaped main body 14.

Groove portion 13 formed by two groove plate portions 12
Although the width and depth of the groove can be set appropriately depending on the use of the groove cover, the groove portion 13 in the embodiment is formed by a V-groove with a width of about 12 mm and a depth of about 6 mm. . Further, the height of the plate-like main body 14 can be made arbitrarily long or short depending on the type of the groove cover.

In addition, in this invention, as shown in FIG. 3, the width b of the upper part of the main member 11 having the groove 13;
The upper distance b between adjacent main members 11, 11 is configured to have the same length. With such a configuration, with this invention, it is possible to obtain a groove cover with fine groove spacing that is one-half of the spacing a between the plate-like bodies 14, which are the conventional main members.

The auxiliary member 16 is made of a known twist bar or the like and is provided perpendicularly to the main member 11.

In addition to the illustrated plate-shaped frame material, the side member 17 has a cross section L.
It can be constructed from a character-shaped angle member or other frame member.

(Operation/Effect) As described above, in the groove cover 10 of this invention, the main member 11 having a Y-shaped cross section and consisting of two groove plate parts 12 is arranged side by side at a predetermined interval on the upper part of the plate-like main body 14. Moreover, since the width of the upper part of the main member 11 and the interval between the upper parts of the adjacent main members 11, 11 are configured to be the same, the following effects are produced.

First of all, since the upper part of the main member 11 is branched into a V-shape, two groove lines are formed in one main member, making it easy to cover fine grooves. can be provided. In particular, according to this invention, as shown in FIG.
Since the spacing b between the grooves is made the same, it is possible to obtain a groove cover with fine groove spacing that is half the spacing a of the plate-like bodies 14, which are the conventional main members. Therefore, without increasing the number of main members,
In other words, it is possible to obtain a groove cover with twice as fine mesh as the conventional main member with the same number of main members, and to provide a groove cover that is relatively economical and lightweight.

As a second point, in the case of the groove cover 10 of this invention, since the V-shaped groove part 13 is formed in the upper part,
Earth and sand and objects falling into the groove part 13 of the lattice part of the groove cover do not fall into the groove. Therefore, all the dirt and objects that fall through the gaps between the grids of the groove plates are prevented from entering the grooves, and the amount of deposits in the grooves can be reduced.

Furthermore, by selecting the angle or depth of the V-shaped groove, an anti-slip effect can be obtained.
It not only improves the safety of pedestrian and vehicle traffic, but also allows for a variety of designs.
The practical effects of this idea are enormous.
