Description

本発明は、路面に降り注いだ雨水が側溝に装着のグレーチングに流入するのを補助し、グレーチングでの越流を抑制するガイドに関する。   The present invention relates to a guide that assists in flowing rainwater that has poured onto a road surface into a grating installed in a side groove and suppresses overflow in the grating.

側溝に溝蓋として用いられるグレーチングは通常、I形断面のメインバーと、平行に並べたメインバーの両端を連結するエンドプレートと、該エンドプレートと平行をなしてメインバーを連結するクロスバーよりなり、路面に降り注いだ雨水は、側溝のグレーチングに飲み込まれて排水されるようになっているが、側溝に向かって傾斜する路面の勾配が大きく、雨水の流れが速くなると、雨水がグレーチングを通りこす越流を生じ、雨水の飲み込みが十分に行われなくなる。こうした雨水に対しては、グレーチングのメインバーのピッチを拡げ、開口面積を広くしても余り効果がない。   The grating used as a groove cover in the side groove is usually composed of an I-shaped main bar, an end plate connecting both ends of the main bar arranged in parallel, and a cross bar connecting the main bar in parallel with the end plate. However, rainwater that has poured onto the road surface is swallowed by the gutters in the gutters and drained. Rub overflow will occur and rainwater will not be swallowed sufficiently. For such rainwater, even if the pitch of the grating main bar is widened and the opening area is widened, there is not much effect.

上記の問題に対処するため、下記特許文献1、2には、スロープを備えたガイド部材を流れ方向上流側のエンドプレートからメインバー間に取付け、スロープによって雨水の落下率を向上させることが提案されている。   In order to cope with the above problems, Patent Documents 1 and 2 below propose that a guide member having a slope is attached between the end plate on the upstream side in the flow direction between the main bars, and the falling rate of rainwater is improved by the slope. Has been.

前述のメインバー間にガイド部材を取付けた構造では、ガイド部材が多数必要で、しかもメインバー間に一つ一つ取付けねばならないため、手間がかかりコスト高となる。しかも歩道に多く採用される、メインバーのピッチが小さなグレーチングには適用することができない。   In the structure in which the guide members are attached between the main bars described above, a large number of guide members are required and must be attached between the main bars one by one. In addition, it cannot be applied to gratings with a small main bar pitch, which are often used in sidewalks.

本発明は、上記の問題を解消し、メインバー間に個々に取付けなくてもよく、細目のグレーチングにも適用可能な越流抑制用のガイドを提供することを目的とする。   An object of the present invention is to solve the above-described problem and provide a guide for overflow suppression that does not need to be individually installed between main bars and can be applied to fine gratings.

請求項1に係わる発明は、側溝に路面より低く設置されるグレーチングに路面から雨水が流入するのを補助するためのスロープを備え、該スロープがグレーチング外側においてグレーチングに沿って延びる越流抑制用のガイドであって、側溝上縁に取付けられるグレーチング用受枠の上端に形成されることを特徴とし、
請求項2に係わる発明は、請求項1に係わる発明のガイドがグレーチングの外側方に形成されることを特徴とする。
The invention according to claim 1 is provided with a slope for assisting inflow of rainwater from the road surface to the grating installed in the side groove lower than the road surface, and the slope is for overflow suppression extending along the grating outside the grating. A guide, characterized in that it is formed at the upper end of a grating receiving frame attached to the upper edge of the side groove,
The invention according to claim 2 is characterized in that the guide according to claim 1 is formed on the outer side of the grating.

請求項3に係わる発明は、側溝に路面より低く設置されるグレーチングに路面から雨水が流入するのを補助するためのスロープを備え、該スロープがグレーチング外側においてグレーチングに沿って延びる越流抑制用のガイドであって、グレーチング外側であるグレーチング上に取付けられることを特徴とし、
請求項4に係わる発明は、側溝に路面より低く設置されるグレーチングに路面から雨水が流入するのを補助するためのスロープを備え、該スロープがグレーチング外側においてグレーチングに沿って延びる越流抑制用のガイドであって、側溝の上端面に形成されることを特徴とする。
The invention according to claim 3 is provided with a slope for assisting inflow of rainwater from the road surface to the grating installed in the side groove lower than the road surface, and the slope is for overflow suppression extending along the grating outside the grating. It is a guide and is mounted on the grating that is outside the grating,
The invention according to claim 4 is provided with a slope for assisting inflow of rainwater from the road surface to the grating installed in the side groove lower than the road surface, and the slope is for overflow suppression extending along the grating outside the grating. It is a guide and is formed on the upper end surface of the side groove.

請求項5に係わる発明は、請求項1〜4に係わる発明において、前記スロープには滑り止め加工が施されることを特徴とする。   The invention according to claim 5 is the invention according to claims 1 to 4, characterized in that the slope is subjected to anti-slip processing.

請求項1に係わる発明のガイドは、グレーチング用受枠の上端に形成され、受枠に装着されるグレーチングの1ないし複数に跨って形成することが可能であり、グレーチングを構成するメインバー間には設けられないため、ガイドの個数が少なくてすみ、スロープを受枠上端にプレス加工等によって一体形成する場合には、ガイドの取付けが不要となり、ガイドを受枠に取付けて形成する場合でもグレーチングを構成するメインバー間に一つ一つ取付けなくてもよく、そのため作業能率が向上し、コストを低減させることができる。またメインバーのピッチの如何に係わらずピッチの小さな網目のグレーチングにも適用可能である。   The guide of the invention according to claim 1 is formed at the upper end of the receiving frame for the grating, and can be formed across one or more of the gratings attached to the receiving frame, and is provided between the main bars constituting the grating. Therefore, the number of guides can be reduced, and when the slope is integrally formed on the upper end of the receiving frame by pressing or the like, it is not necessary to mount the guide. It is not necessary to attach each one between the bars, so that the work efficiency can be improved and the cost can be reduced. Further, the present invention can be applied to grating having a small pitch regardless of the pitch of the main bar.

スロープは受枠上端からグレーチング上に迫り出して形成されていても、グレーチングを受枠とガイド間に差込むようにして挿入することにより、受枠に装着することが可能であるが、請求項2に係わる発明のガイドのように、スロープがグレーチングの外側方に形成されていると、グレーチングを受枠に装着する際、ガイドが邪魔になることはなく、グレーチングの装着が容易となる。   Even if the slope is formed to protrude from the upper end of the receiving frame onto the grating, it can be attached to the receiving frame by inserting the grating so as to be inserted between the receiving frame and the guide. If the slope is formed on the outer side of the grating as in the guide, the guide does not get in the way when the grating is mounted on the receiving frame, and the mounting of the grating is facilitated.

請求項3に係わる発明のガイドは、グレーチング上に1ないし複数のグレーチングに跨って取付けることができ、グレーチングを構成するメインバー間には設けられないため、ガイドの個数が少なくてすみ、ガイドを取付ける作業を軽減することができる。またメインバーのピッチがどのようなグレーチングに対しても適用可能である。なお、本発明に係わるガイドのグレーチングへの取付けは、グレーチングへの固定のみならず、グレーチングに固定しないでグレーチング用受枠に固定し、グレーチング上に単に載置して取付けられるものを含むものである。   The guide of the invention according to claim 3 can be mounted on one or more gratings on the grating, and is not provided between the main bars constituting the grating. Installation work can be reduced. Further, the present invention can be applied to any grating having a main bar pitch. Note that the attachment of the guide according to the present invention to the grating includes not only fixing to the grating but also fixing to the grating receiving frame without fixing to the grating, and simply mounting on the grating.

請求項4に係わる発明のガイドは、側溝に形成されるため、ガイドを側溝とは別に設ける必要がなく、メインバーのピッチがどのようなグレーチングに対しても適用可能である。
請求項5に係わる発明のガイドによると、走行する車両のタイヤや歩行者のスリップを防止することができる。
Since the guide of the invention according to claim 4 is formed in the side groove, it is not necessary to provide the guide separately from the side groove, and the pitch of the main bar can be applied to any grating.
According to the guide of the invention concerning claim 5, it is possible to prevent the tire of a traveling vehicle and the pedestrian from slipping.

以下、本発明の実施形態のガイドについて図面により説明する。
グレーチング1は、図1〜図3に示すように、I形断面のメインバーであるベアリングバー2と、平行に並べたベアリングバー2の両端を連結するエンドプレート3と、該エンドプレート3と平行をなしてベアリングバー2の上端を連結するクロスバーとしての丸棒又はツイストバー4とよりなっている。
Hereinafter, a guide according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the grating 1 includes a bearing bar 2 that is a main bar having an I-shaped cross section, an end plate 3 that connects both ends of the bearing bars 2 arranged in parallel, and a parallel to the end plate 3. And a round bar or a twist bar 4 as a cross bar connecting the upper ends of the bearing bars 2.

グレーチング1が装着される受枠5は、水平部5aと垂直部5bよりなるL形断面をなし、垂直部5bはベアリングバー1と実質的に同じ高さとなっている。そして垂直部上端には、上面を図3に示すように滑り止め加工し、グレーチング外側方の路面8に向かって登るスロープとしたガイド6がプレス加工によって一体に屈曲形成されている。このガイド6は受枠とは別体で、垂直部上端に溶接にて取付けてもよい。   The receiving frame 5 on which the grating 1 is mounted has an L-shaped cross section composed of a horizontal portion 5 a and a vertical portion 5 b, and the vertical portion 5 b has substantially the same height as the bearing bar 1. Further, the upper portion of the vertical portion is formed with a non-slip-processed upper surface as shown in FIG. 3, and a guide 6 as a slope that climbs toward the road surface 8 on the outer side of the grating is integrally bent by pressing. This guide 6 is separate from the receiving frame and may be attached to the upper end of the vertical portion by welding.

グレーチング1は、受枠5に装着された状態で図2に示すように路面よりも低くなっており、スロープ端は、図示するように路面8と段差がなく、垂直部5bとの接続部分は受枠5に装着されるグレーチング1とほぼ同じレベルになっているため、スロープはグレーチング1から路面に向かって登るように形成されている。   The grating 1 is lower than the road surface as shown in FIG. 2 when mounted on the receiving frame 5, and the slope end has no step with the road surface 8 as shown in the figure, and the connecting portion between the vertical portion 5 b is the receiving frame. Since the level is substantially the same as that of the grating 1 mounted on the slope 5, the slope is formed so as to climb from the grating 1 toward the road surface.

本実施形態のガイド6は以上のように、受枠5の垂直部端に形成され、グレーチング1を構成するベアリングバー1間に一つ一つ取付けなくてもよいことはもちろん、グレーチングごとに取付けなくてもよく、複数のグレーチング1に跨って形成することができる。とくにガイド6を受枠5にプレス加工によって屈曲形成する場合には、ガイド6の取付けが不要となり、製作コストをより低減させることができる。またベアリングバー1のピッチの如何にかかわらず、適用でき、スロープ上面の滑り止め加工によって車両や歩行者がスリップするのを防ぐことができ、安全である。   As described above, the guides 6 of the present embodiment are formed at the end of the vertical portion of the receiving frame 5 and need not be attached one by one between the bearing bars 1 constituting the grating 1. It may be formed over a plurality of gratings 1. In particular, when the guide 6 is bent and formed on the receiving frame 5 by pressing, it is not necessary to attach the guide 6 and the manufacturing cost can be further reduced. Moreover, it can be applied regardless of the pitch of the bearing bar 1, and the vehicle and pedestrian can be prevented from slipping by the slip prevention processing on the upper surface of the slope, which is safe.

図示する前記実施形態のガイド6は、グレーチング1が装着される左右の受枠5にそれぞれ形成されているが、雨水の流れ方向上流側の受枠5にのみ設けてもよい。   The guides 6 of the embodiment shown in the figure are respectively formed on the left and right receiving frames 5 on which the grating 1 is mounted, but may be provided only on the receiving frames 5 on the upstream side in the rainwater flow direction.

図4に示す実施形態においては、図1〜図3に示す実施形態における雨水の流れ方向上流側の受枠5の垂直部5bを路面8と段差なく高く形成するとともに、垂直部5bの上端よりガイド9をグレーチング側に屈曲形成して、先端がグレーチング1に接し、その上面を滑り止め加工したスロープとしたもので、雨水の流れ方向下流側のガイド6は図1〜図3に示す実施形態と同様で代わりがない。この実施形態においても流れ方向下流側のガイド6は省いてもよい。   In the embodiment shown in FIG. 4, the vertical portion 5 b of the receiving frame 5 on the upstream side in the rainwater flow direction in the embodiment shown in FIGS. 1 to 3 is formed so as to be level with the road surface 8 and is guided from the upper end of the vertical portion 5 b. 9 is bent on the grating side, the tip is in contact with the grating 1 and the upper surface thereof is a non-slip processed slope, and the guide 6 on the downstream side in the rainwater flow direction is the embodiment shown in FIGS. Similar and no substitute. Also in this embodiment, the guide 6 on the downstream side in the flow direction may be omitted.

本実施形態において、受枠5へのグレーチング1の装着は、流れ方向下流側よりグレーチング1を受け枠5の水平部5aとガイド9との間に差込むように挿入することにより行われ、ガイド9が内側に迫り出していてもグレーチング1の受枠5への装着は支障なく行える。   In the present embodiment, the mounting of the grating 1 to the receiving frame 5 is performed by inserting the grating 1 from the downstream side in the flow direction so as to be inserted between the horizontal portion 5 a of the frame 5 and the guide 9. The grating 1 can be mounted on the receiving frame 5 without any problem even if it protrudes inward.

図5〜図7に示す実施形態においては、断面が楔状のガイド11が受枠12に装着されるグレーチング1の上面両側に好ましくは溶接にて固着され、上面のスロープには、前記実施形態のガイド6と同様、滑り止め加工が施されている。なお、本実施形態の受枠12は、垂直部12bが路面8との段差をなくし、かつグレーチング1に取付けたガイド11端のレベルと同程度となるように、前記実施形態の受枠5の垂直部5bより若干高く形成されている。   In the embodiment shown in FIGS. 5 to 7, the guide 11 having a wedge-shaped cross section is fixed to both sides of the upper surface of the grating 1 attached to the receiving frame 12, preferably by welding, and the guide of the above embodiment is attached to the slope of the upper surface. Similar to 6, anti-slip processing is applied. Note that the receiving frame 12 of the present embodiment has a vertical portion 12b that has no difference in level from the road surface 8 and has the same level as the level of the end of the guide 11 attached to the grating 1. It is formed slightly higher than 5b.

本実施形態においても、前記実施形態と同様、ガイド11はエンドプレート2に沿って、その全長に設けられ、また一連に並べたグレーチングに沿って取付けることも可能であり、ガイドをベアリングバー間に一つ一つ設けるのに比べ、部品点数が少なくてすみ、作業能率が向上して製作コストを低減させることができること、ベアリングバーのピッチの如何にかかわらず、取付けることができること、スロープ上面の滑り止め加工によって車両や歩行者がスリップするのを防ぐことができること等の効果を有する。
本実施形態においても流れ方向下流側のガイド11は省いてもよい。
Also in this embodiment, the guide 11 is provided along the end plate 2 along its entire length, and can be attached along a series of gratings, as in the above-described embodiment. Compared to installing each one, the number of parts can be reduced, the work efficiency can be improved and the production cost can be reduced, it can be installed regardless of the pitch of the bearing bar, and the slope top can be slipped. It has effects, such as being able to prevent a vehicle or a pedestrian from slipping by stop processing.
Also in this embodiment, the guide 11 on the downstream side in the flow direction may be omitted.

図8は更に別の実施形態について示すもので、グレーチング用受枠15が取着される側溝16の上端面が雨水流入の補助機能を果たすガイドとなるスロープ17に形成される。
本実施形態においても、流れ方向下流側の側溝にはスロープを形成しなくてもよい。
FIG. 8 shows still another embodiment, and the upper end surface of the side groove 16 to which the grating receiving frame 15 is attached is formed on a slope 17 that serves as a guide for performing the rainwater inflow assisting function.
