Description

本願発明は絶縁カバー、絶縁シート、およびこれらを用いる絶縁構造にかかるものであり、具体的には、例えば、新幹線ホームなどの鉄道線路を横断する門型ビーム材の水平梁に着脱自在に取付けて、鳥獣その他の飛来物とトロリー線との地絡事故を防止するための、ＦＲＰ製の現場施工性に優れた軽量で安価な地絡防止用のリップ付溝型絶縁カバーのような製品に適用することができる。 The present invention relates to an insulating cover, an insulating sheet, and an insulating structure using these. Specifically, for example, it is detachably attached to a horizontal beam of a gate-type beam material crossing a railway track such as a Shinkansen platform. Applicable to products such as FRP-made grooved insulation covers with lips for preventing ground faults that are excellent in on-site workability to prevent ground faults between birds and animals and other flying objects and trolley wires. can do.

図４は、新幹線ホームにおけるトロリー線と水平梁の位置関係を示す略図である。ここに示すように、新幹線ホームなどの鉄道線路を横断する門型ビーム材の水平梁とその下方直角方向に設置されているトロリー線との離隔間隔は比較的小さいものである。
特に新幹線の給電電圧は在来線に比べて高く、また、トロリー線と水平梁との離隔間隔（図４におけるｈまたはｈ１）が小さいため、駅構内などにおいてはカラスなどの大形の鳥などが飛来した場合、水平梁と鳥の広げた翼とがトロリー線と接触して地絡事故などを惹起する懸念があった。 FIG. 4 is a schematic diagram showing the positional relationship between the trolley line and the horizontal beam in the Shinkansen platform. As shown here, the separation distance between the horizontal beam of the gate-type beam material crossing the railway line such as the Shinkansen platform and the trolley wire installed in the direction perpendicular to the lower side thereof is relatively small.
In particular, the power supply voltage of the Shinkansen is higher than that of conventional lines, and the distance between the trolley line and the horizontal beam (h or h1 in Fig. 4) is small. There was a concern that the horizontal beam and the wings spread by the bird would come into contact with the trolley wire and cause a ground fault.

従来、この地絡事故防止のため、図４に示すように、ＦＲＰなどの絶縁板材１８を現場にて切断加工して、Ｌ型アングルなどの金属部材を利用して水平梁７に取付けていたが、現物合わせの現場施工であるため取付け工事に時間を要するとともに、前記Ｌ型アングルなどによる固定する構造であるため重く、また、固定金具が外部に露出しているため、トロリー線と水平梁との絶縁離隔距離（ｈまたはｈ1）が短くなる欠点があった。 Conventionally, in order to prevent this ground fault accident, as shown in FIG. 4, the insulating plate material 18 such as FRP is cut on-site and attached to the horizontal beam 7 using a metal member such as an L-shaped angle. However, it takes time to install because it is on-site construction of the actual product, it is heavy because it is fixed by the L-shaped angle, etc., and the fixing bracket is exposed to the outside, so trolley wires and horizontal beams Insulation separation distance (h or h 1) is shortened.

[実施例]
以下に、本発明による絶縁カバーにかかる第１の実施例として、新幹線ホームなどの鉄道線路を横断する門型ビーム材の水平梁用地絡防止用リップ付溝型絶縁カバーについて、図１〜図３により詳細に説明する。図１は、本発明の第１の実施例による地絡防止用リップ付溝型絶縁カバー１の６面図であり、それぞれ、（ａ）は上面図，（ｂ）は右側面図、（ｃ）は左側面図、（ｄ）は上側面図、（ｅ）は下側面図、（ｆ）は底面図、（ｇ）はＡ部の拡大図である。 [Example]
Hereinafter, as a first embodiment of the insulating cover according to the present invention, a grooved insulating cover with a lip for ground beam prevention for horizontal beams of a gate beam material that crosses a railway line such as a Shinkansen platform will be described with reference to FIGS. Will be described in more detail. FIG. 1 is a six-side view of a grooved insulating cover 1 with a lip for preventing ground fault according to a first embodiment of the present invention, wherein (a) is a top view, (b) is a right side view, and (c). ) Is a left side view, (d) is a top side view, (e) is a bottom side view, (f) is a bottom view, and (g) is an enlarged view of part A.

図１において、１は地絡防止用リップ付溝型絶縁カバーで、ＦＲＰ等の樹脂で成型され、その断面形状は、例えば、（ｂ）図からわかるように長リップ２および短リップ３を設けたリップ付の溝型断面形状とされ、それぞれの断面略Ｕ字形の溝の深さ(リップ長)が異なっている。また、前記の長リップおよび短リップは溝側に撓んだ形状とされており、水平梁７に取付けた際に前記の長短リップ部と突起４とで水平梁７のフランジ８を挟み込むように構成されている。 In FIG. 1, reference numeral 1 denotes a grooved insulating cover with a lip for preventing a ground fault, which is molded from a resin such as FRP, and has a long lip 2 and a short lip 3 as shown in FIG. The groove-shaped cross-sectional shape with a lip is different, and the depth (lip length) of each groove having a substantially U-shaped cross section is different. Further, the long lip and the short lip are bent to the groove side, and the flange 8 of the horizontal beam 7 is sandwiched between the long and short lip portion and the protrusion 4 when attached to the horizontal beam 7. It is configured.

また、ボルト装置５で固定される側の長リップ２は、反対側の短リップ３に比べて、そのリップ長が長く形成されている。この理由を、図２の絶縁カバー施工方法における（イ）から（ニ）の取付け施工図で説明する。まず、門型ビームＨ型鋼材の水平梁７のフランジ８の幅（Ｂ）よりも，リップ付溝型絶縁カバー１の内壁と短リップ縁部との間隔（Ｌｘ）を同等程度の広さに形成しておき、図２（イ）のようにフランジ８の一端部を長リップ２側の内壁に突当て、他端の短リップ３側を図２（ロ）のように矢印方向に引上げて同図の左方向にずらすと、図２（ハ）に示すように長リップ２側の内壁とフランジ８の縁部との間に空隙部９が形成される。 Further, the long lip 2 on the side fixed by the bolt device 5 has a longer lip length than the short lip 3 on the opposite side. The reason for this will be described with reference to the installation construction diagrams (a) to (d) in the insulating cover construction method of FIG. First, the distance (Lx) between the inner wall of the grooved insulating cover 1 with a lip and the short lip edge is made to be equal to the width of the flange 8 of the horizontal beam 7 of the portal beam H-shaped steel material (B). As shown in FIG. 2 (a), one end of the flange 8 is abutted against the inner wall on the long lip 2 side, and the other short lip 3 side is pulled up in the direction of the arrow as shown in FIG. 2 (b). When shifted to the left in the figure, a gap 9 is formed between the inner wall on the long lip 2 side and the edge of the flange 8 as shown in FIG.

上記のリップ付溝型絶縁カバー１の取付けに際して、前記リップ付溝型絶縁カバー１はＦＲＰ製であるから若干の可撓性を有するので、前記のリップ付溝型絶縁カバー１の内壁と短リップ縁部との間隔（Ｌｘ）をフランジ８の幅（Ｂ）より若干狭い寸法に形成した場合でも取付け可能である。４はリップ付溝型絶縁カバーに設けられた複数条の突起であり、リップ付溝型絶縁カバー１の幅方向の剛性を薄い板材料でも高め得る作用があるから、リップ付溝型絶縁カバーの軽量化を図ることができる。なお、突起の突出方向は、図示のように、リップ付溝型絶縁カバー１の内周方向ばかりでなく、外周方向に突設させて設けることもできる。 When mounting the above-mentioned grooved insulating cover 1 with a lip, since the grooved insulating cover 1 with a lip is made of FRP and has some flexibility, the inner wall of the grooved insulating cover 1 with a lip and a short lip are provided. Even if the distance (Lx) to the edge is slightly narrower than the width (B) of the flange 8, it can be mounted. Reference numeral 4 denotes a plurality of protrusions provided on the grooved insulating cover with lip, which has the effect of increasing the rigidity in the width direction of the grooved insulating cover with lip 1 even with a thin plate material. Weight reduction can be achieved. As shown in the figure, the protruding direction of the protrusions can be provided not only in the inner peripheral direction of the grooved insulating cover 1 with lip but also in the outer peripheral direction.

この図１では、突起４は、リップ付溝型絶縁カバー１の短辺と平行する方向に延在するようにして複数条を設けている。しかしこれに限らず、突起４が延在する方向を、リップ付溝型絶縁カバー１の長手方向すなわち長辺と平行する方向として設けることもできる。なお、前記のように突起４を長手(長辺)方向に複数条設けた場合には、幅(短辺)方向に伸縮自在となるので、水平梁７のフランジ幅（Ｂ）の寸法が若干大きくなってもリップ付溝型絶縁カバー１取付けることができ、製造金型費などを削減できて好適なものとなる。 In FIG. 1, the protrusion 4 is provided with a plurality of strips so as to extend in a direction parallel to the short side of the grooved insulating cover 1 with a lip. However, the present invention is not limited to this, and the direction in which the protrusion 4 extends may be provided as the longitudinal direction of the lip grooved insulating cover 1, that is, the direction parallel to the long side. When a plurality of protrusions 4 are provided in the longitudinal (long side) direction as described above, the flange 4 (B) has a slight dimension because it can expand and contract in the width (short side) direction. Even if the size is increased, the grooved insulating cover 1 with a lip can be attached, and the manufacturing die cost can be reduced.

次に、前記空隙部９の寸法に適合する形状のＦＲＰ製テーパー付き中空四角管からなる楔６を前記空隙部９に差込んで、側面のがたをなくすようにし、図２（ハ）の如くに形成する。
その次に、図２（ニ）のように、前記長リップ２と楔１０とを脱落防止用のボルト装置５で固定して、現地におけるリップ付溝型絶縁カバー１の取付け作業は完了する。 Next, a wedge 6 made of an FRP tapered hollow square tube having a shape that matches the size of the gap 9 is inserted into the gap 9 so as to eliminate side play, as shown in FIG. It forms as follows.
Next, as shown in FIG. 2 (d), the long lip 2 and the wedge 10 are fixed by the bolt device 5 for preventing the drop off, and the installation work of the grooved insulating cover 1 with the lip on the site is completed.

以上の施工手順を、さらに、絶縁カバーの取付け施工手順を示す斜視略図である図３（イ）〜（ハ）により説明する。
図３（イ）は、トロリー線１１の上方に位置する門型ビームＨ型鋼材水平梁７のトロリー線１１側フランジ８の長手方向に、約１ｍ前後の長さのリップ付溝型絶縁カバー１を前記フランジ８に取付ける状況を示している。すなわち、リップ付溝型断面のリップ付溝型絶縁カバー１をトロリー線１１側フランジ８の側面側から取付けた状況の右側斜視図は、図３（ロ）のようになる。また、図３（ロ）の左方向（Ｃ側から見た）からの斜視図は図３（ハ）のようになり、長リップ２側の内面側壁とフランジ８の縁部とに形成される空隙部９に楔６を差込んでボルト装置５により固定する構造は、リップ付溝型絶縁カバー１の固定と脱落防止を兼ねるようにしたものである。 The above construction procedure will be further described with reference to FIGS. 3A to 3C, which are schematic perspective views showing the installation construction procedure of the insulating cover.
FIG. 3A shows a grooved insulating cover 1 with a lip having a length of about 1 m in the longitudinal direction of the flange 8 on the trolley wire 11 side of the horizontal beam 7 of the portal beam H-shaped steel material 7 located above the trolley wire 11. Is shown attached to the flange 8. That is, a right perspective view of the situation where the grooved insulating cover 1 with a lip having a cross section with a lip is attached from the side surface side of the flange 8 on the trolley wire 11 side is as shown in FIG. 3B is a perspective view from the left direction (viewed from the C side) as shown in FIG. 3C, and is formed on the inner side wall on the long lip 2 side and the edge of the flange 8. FIG. The structure in which the wedge 6 is inserted into the gap 9 and fixed by the bolt device 5 serves to both fix the lip-shaped grooved insulating cover 1 and prevent it from falling off.

なお、図５の本発明による絶縁カバーの設置構成図に示すように、門型ビームＨ型鋼材水平梁の下方に間隔を置いて複数条のトロリー線が存在するような場合には、前記トロリー線の上部水平梁のフランジ部に、前記リップ付溝型絶縁カバー１を追加設置すればよい。また、設置に際しては１ｍ程度の比較的短尺なリップ付溝型絶縁カバー１を、複数個直列に並べて取付けても良い。 In addition, as shown in the installation configuration diagram of the insulating cover according to the present invention in FIG. 5, when a plurality of trolley wires are present at intervals below the portal beam H-shaped steel horizontal beam, the trolley The grooved insulating cover 1 with lips may be additionally installed on the flange portion of the upper horizontal beam of the wire. When installing, a plurality of relatively short lip grooved insulating covers 1 of about 1 m may be arranged in series.

以上、本発明の一実施形態として、新幹線ホームなどの鉄道線路を横断する門型ビーム材の水平梁とその下方直角方向に設置されているトロリー線との地絡事故防止のため、前記門型ビーム材の水平梁にリップ付溝型絶縁カバーを取付ける方法について説明してきたが、本発明の趣旨を逸脱しない範囲で、例えば、次のような場合にも利用できるものである。

However, the method can be used in the following cases, for example, without departing from the spirit of the present invention.
