Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grating used for openings in side gutters, cross ditches, structures, etc.

[Conventional technology]

As a grating for the purpose of odor prevention, for example, as shown in Japanese Utility Model Application Publication No. 51-20359,
Attach a water conductive steel plate and a water receiving steel plate to the side of the main shaft steel plate (main plate) of the grating at different levels so that the water conductive steel plate is on top, and so that the ends of both steel plates overlap when viewed from above. Some steel plates have an odor-preventing film provided at the tip thereof so as to be in close contact with a water-receiving steel plate located below.

[Problem that the invention attempts to solve]

However, in the conventional grating mentioned above, a water-conducting steel plate, a water-receiving steel plate, and an odor prevention film are provided between the main shaft steel plates, so the space width between the main shaft steel plates becomes narrow, making it difficult to smoothly remove dirt, fallen leaves, etc. that enter this space. It is difficult to drop the main shaft steel plates, and there is even a risk that the space between the main shaft steel plates will be clogged with such debris and fallen leaves. In addition, the odor prevention film is provided in close contact with the water-receiving steel plate located below, and as mentioned above, the space between the main shaft steel plates is easily clogged with dirt and fallen leaves. The problem is that the sludge that accumulates at the bottom is difficult to dry, making it unsanitary.

The present invention solves the above-mentioned problems, and allows wastewater treatment and the dropping of garbage, fallen leaves, etc. that have entered the gap between the main plates into the grooves to be carried out in the same way as before, and moreover, The purpose is to obtain a grating that can maintain sanitary conditions below.

[Means to solve the problem]

In order to achieve the above object, the grating according to the present invention includes a grating body having a plurality of strip-shaped main plates, and a plurality of shields inclined in the same direction so as to be located below the lower end of the main plates. A falling gap with an open bottom is formed below the gap between the main plates by only the shielding member, and the plurality of shielding members cover the bottom of the gap between the main plates from above. It is designed to be visually shielded and to allow debris, fallen leaves, etc. that have entered the gap between the main plates to fall through the falling gap.

[Effect]

The grating of the present invention is provided with a plurality of shielding members inclined in the same direction so as to be located below the lower end of the main plate of a grating body having a plurality of strip-shaped main plates, and only by these shielding members. Since the falling gap, which is open at the bottom, is formed below the gap between the main plates, the width of the gap between the main plates is not narrowed by the shielding member. When used in a side gutter, etc., dirt, fallen leaves, etc. that have entered the gap between the main plates can fall smoothly through the gap between the main plates and the falling gap that is open at the bottom.
Since the falling gap is open at the bottom, ventilation is good. In addition, since the plurality of shielding members shield the lower part of the gap between the main plates when viewed from above, it is possible to block light rays from entering the gutter, and this grating can be used in high places such as structures. When in use, there is no visibility through the void.

〔Example〕

An example of the grating of the present invention will be described based on FIGS. 1 and 2.

In the figure, 1 is a conventionally known grating main body, which is a frame member 2 formed of a band-shaped metal plate.
, a plurality of main plates 3 made of band-like metal plates installed in the frame member 2 with their side faces facing each other and spaced apart from each other and substantially parallel; and each main plate 3 perpendicular to the main plate 3. It consists of a crossbar 4 fixed to the

Reference numeral 5 designates a plate-shaped shielding member attached to the lower end edge of each main plate 3 by welding or the like so as to protrude downward, and is formed to have approximately the same length as the main plate 3 and to be inclined. This shielding member 5 opens a gap 6 between the main plates 3 into a fall gap 7 (see FIG. 2) that allows debris, fallen leaves, etc. that have entered the gap to fall.
It is formed in a shield shape with only . That is, the shielding member 5 is provided at an angle so as to be located below the lower end of the main plate 3, and the falling gap 7, which is open from below, is provided only by the shielding member 5.
is formed below the gap 6 between the main plates 3. More specifically, a plurality of shielding members 5 inclined in the same direction are provided below the gap 6 between the main plates 3, and only the shielding members 5 form a falling gap 7 with an open bottom. The shielding member 5 is made of not only metal but also synthetic resin, rubber, and other weather-resistant materials.

As shown in FIG. 2, the shielding member 5 is provided to almost reach the extension line C of the opposing main plate 3, but it may be made to protrude further than this extension line (as shown by the imaginary line). ), or it may be placed slightly in front of it.

Further, the shielding member, as shown in FIG. 3,
It may be attached to the grating body 1 using fasteners such as bolts and nuts 10.

FIG. 4 shows the shielding member 5 for the main plate 3.
FIG. 7 is a cross-sectional view showing still another embodiment of the attachment means of FIG. In this figure, reference numeral 11 denotes a mounting part with a concave cross section integrally provided on the upper edge of the shielding member 5 made of rubber or synthetic resin, and a locking part bent inward at the tip of each opposing wall 12. 13 are provided.
Then, the mounting portion 11 is elastically deformed, the lower end of the main plate 3 is inserted into the mounting portion 11, and the locking portion 13 is elastically locked to the protruding step portion 14 at the lower end of the main plate 3. A shielding member 5 is removably attached to 3.

In this embodiment, it is extremely easy to attach the shielding member 5 to the main plate 3. For example, during transportation or storage, the shielding member 5 can be separated to reduce its bulk and then attached at the construction site. Yes, grating body 1 and shielding member 5
can be easily transported and stored.

The mounting portion 11 may be formed of an elastic metal plate such as a steel plate, and may be fixed to the main body portion of the shielding member 5 with rivets or the like.

In attaching the shielding member 5 to the main plate 3, in the embodiment shown in FIGS. 1 to 4, the shielding member 5 is attached to each of the main plates 3, but as shown in FIG. 5A, It is also possible to attach shielding members 5 to every other main plate 3. In this embodiment, the width D of the shielding member 5 is widened to form a plurality of gaps 6 (two in the drawing).
The spaces 6, 6) are simultaneously shielded. Further, as shown in FIG. 5B, a shielding member 5 can be formed at the lower end of the main plate 3 in a direction perpendicular to the lower end.

6A to 6C show the shielding member 5 in various shapes and in an attached state.

The shielding members 5 shown in FIGS. 1 to 6 are each attached to the main plate 3, but as shown in FIG. A member 2a is fixed by welding or the like, and both ends of the shielding member 5 are attached to the frame member 2a, and the main plate 3,
The gap 6 between the three can also be made into a shield, leaving a fall gap 7.

FIG. 8 shows still another embodiment, in which a shielding member 5 is provided below the grating body 1 separately from the grating body 1. This shielding member 5
is installed in a rectangular frame 2b by welding or the like so that the gap 6 between the main plates 3 of the grating body 1 is inclined so as to form a shield while leaving a falling gap 7. 16 is a receiving frame, 17 is a gutter,
Reference numeral 18 denotes a support stepped portion of the rectangular frame body 2b.

[Effect of idea]

As explained above, the grating according to the present invention includes a plurality of shielding members inclined in the same direction so as to be located below the lower end of the main plate of the grating body having a plurality of strip-shaped main plates. A falling gap with an open bottom is formed below the gap between the main plates by only the shielding member, and the plurality of shielding members form a fall gap that is open at the bottom, and the plurality of shielding members allows the lower part of the gap between the main plates to be formed when viewed from above. In addition to providing a shielding shape, dirt, fallen leaves, etc. that have entered the gap between the main plates are allowed to fall through the falling gap.

Therefore, when this grating is used, for example, in a side gutter, the gap width between the main plates is not narrowed by the shielding member, so that any debris or fallen leaves that have entered the gap between the main plates can be quickly removed from the side gutter, etc. It can be dropped inside. Since the falling gap is open at the bottom, it has good ventilation, and when there is little water in the gutter, the inside can be easily dried. Therefore, rotting of garbage accumulated inside gutters etc. is prevented,
No bad odor is generated.

In addition, since the lower part of the gap between the main plates is shielded by the shielding member when viewed from above, it is difficult for light rays to enter the inside of the gutter etc.
Since the inside of the gutter etc. is dark, it is difficult to see the inside of the gutter etc. from above the grating.
Even if there is garbage or other filth inside the gutters,
I have never felt sick because of them. And even if there is soil inside the gutters etc.
Since it is difficult for light to enter, it is difficult for weeds to grow, and weeds do not impede water flow through gutters, etc., and there is no possibility that trash will accumulate in them and worsen water flow. In combination with the above-mentioned good ventilation, the side gutters etc. can be made sanitary.

Furthermore, when the grating according to the present invention is used for an opening at a high place in a structure, the lower part of the cavity in the main plate is shielded when viewed from above, so that it is difficult to see through the cavity in the grating. This can eliminate the feeling of anxiety caused by heights. In this case, even if the bottom of the grating can be seen slightly from the falling gap, it is only a small part and is in the form of a small line, so there is no risk of causing anxiety.
