Description

本発明は、例えば鉄道の線路の脇や変電施設内に設けられているケーブルトラフの布設に係るもので、特にトラフ用蓋、このトラフ用蓋の連結部材、これらトラフ用蓋やトラフ用蓋の連結部材を用いたトラフ、及びトラフへのトラフ用蓋の布設方法に関するものである。   The present invention relates to the laying of a cable trough provided, for example, on the side of a railway track or in a substation facility, and in particular, a trough lid, a connecting member for the trough lid, the trough lid, and the trough lid. The present invention relates to a trough using a connecting member and a method for laying a trough lid on the trough.

従来から、例えば鉄道の線路脇や変電施設内には、電力ケーブルや通信ケーブル等を保護し、布設するためのケーブルトラフが設けられている。
このケーブルトラフは、通常、断面略Ｕ字状のコンクリート製のトラフ本体と、このトラフ本体の上部開口部をトラフ本体全長に亘って覆う、これもコンクリート製のトラフ用蓋とからなっていて、トラフ本体内部に前述したケーブル類を収納した後、トラフ本体上部の開口部をトラフ用蓋で全長に亘って覆うものである。 Conventionally, a cable trough for protecting and laying a power cable, a communication cable, and the like has been provided, for example, on the side of a railway line or in a substation facility.
This cable trough is usually composed of a concrete trough body having a substantially U-shaped cross section and an upper opening of the trough body covering the entire length of the trough body, which is also a concrete trough lid, After the above-described cables are housed inside the trough body, the opening at the top of the trough body is covered with the trough lid over the entire length.

ところで近年、ケーブルトラフの布設を容易にしたい、との要望が多く、そのためケーブルトラフ用蓋を合成樹脂にする試みや、トラフ用蓋だけに留まらずトラフ本体及びトラフ用蓋のすべてを合成樹脂にする試みがなされている。とりわけ合成樹脂の再利用の観点から、前述したトラフ本体やトラフ用蓋すべてを合成樹脂のリサイクル品でまかなう試みも行われるようになってきている。   By the way, in recent years, there has been a great demand for easy installation of cable troughs, so attempts to make cable trough lids synthetic resin, and not only trough lids but all trough bodies and trough lids made of synthetic resin. Attempts have been made. In particular, from the viewpoint of reusing synthetic resin, attempts have been made to cover all the trough body and trough lid described above with recycled synthetic resin.

このように少なくともトラフ用蓋を合成樹脂製のものに代えると、布設工事の際、作業者の負担が大きく改善される。すなわちトラフ用蓋が軽くなった分、トラフ用蓋の運搬やトラフ本体へトラフ用蓋を被せる作業が容易になり、作業者の腰痛対策にも有効である。また、重機を使用しなくとも運搬、施工が可能である上、工期が短縮でき工費の節減にもつながる。またリサイクル材を使用すれば使用後も再成型し、再利用することもできる。もちろんトラフ用蓋のみならずトラフ本体も含めて合成樹脂化すれば、その効果は極めて大きい。   Thus, if at least the trough lid is replaced with a synthetic resin one, the burden on the operator is greatly improved during the construction work. That is, as the trough lid becomes lighter, the transportation of the trough lid and the operation of covering the trough main body with the trough lid are facilitated, which is effective for countermeasures for the back pain of the operator. In addition, transportation and construction are possible without using heavy machinery, and the construction period can be shortened, leading to a reduction in construction costs. If recycled materials are used, they can be re-molded and reused after use. Of course, if a synthetic resin including not only the trough lid but also the trough body is used, the effect is extremely large.

しかしながらトラフ用蓋を合成樹脂化した場合、以下のような問題がある。
すなわち、トラフ用蓋を合成樹脂化すると、当然のことながら従来のコンクリート製の場合に比して大幅に軽量になる。
具体的には、サイズがほぼ同じトラフ用蓋で比較すると、合成樹脂製のトラフ用蓋ではコンクリート製の蓋の約１／１０程度になる。その結果、ケーブルトラフの傍を電車が走行した場合、その風圧でトラフ用蓋が飛び上がってトラフ本体から外れてしまう、という問題がある。もちろん台風等風が強い場合にも同様のことが起こり得る。 However, when the trough lid is made of synthetic resin, there are the following problems.
That is, when the trough lid is made of synthetic resin, it is naturally lighter than the case of conventional concrete.
Specifically, when compared with trough lids of approximately the same size, a synthetic resin trough lid is about 1/10 that of a concrete lid. As a result, there is a problem that when the train travels near the cable trough, the trough lid jumps up from the trough body due to the wind pressure. Of course, the same can happen when a typhoon or other wind is strong.

風や電車の風圧でトラフ用蓋が飛んで外れると、通過中の電車にトラフ用蓋が当たったり、線路脇を歩いている歩行者等に当たる可能性もある。また、トラフ本体内部に収納されているケーブル類が直接風雨に曝される、とか、最悪の場合にはケーブル類も舞い上がってトラフ本体から飛び出してしまう、ということも引き起こされ得る。   If the trough lid flies off due to wind or the wind pressure of the train, the trough lid may hit the passing train, or it may hit a pedestrian walking along the track. In addition, the cables housed in the trough body may be directly exposed to wind and rain, or in the worst case, the cables may rise and jump out of the trough body.

そこで電車の風圧や風によってケーブルトラフ用蓋が簡単に外れないように、隣接するトラフ用蓋同士を連結金具で連結する方法が提案されている（特許文献１）。
特許文献１に開示されている方法は、図１０が示すように隣接するトラフ用蓋３の連結端面を中に挟んで、当該連結端面部の近傍にトラフ用蓋３の表裏を貫通する貫通孔８ａ、８ｂをそれぞれ穿ち、この貫通孔８ａ、８ｂに略Ｕ字状のトラフ用蓋の連結部材６の脚部７、７を挿通して両トラフ用蓋３同士を連結するものである。 In view of this, there has been proposed a method of connecting adjacent trough lids with a connecting metal fitting so that the cable trough lids are not easily removed by the wind pressure or wind of a train (Patent Document 1).
As shown in FIG. 10, the method disclosed in Patent Document 1 has a through-hole penetrating the front and back of the trough lid 3 in the vicinity of the connection end surface portion with the coupling end surface of the adjacent trough lid 3 interposed therebetween. 8a and 8b are respectively drilled, and the leg portions 7 and 7 of the connecting member 6 of the substantially U-shaped trough lid are inserted into the through holes 8a and 8b to connect the trough lids 3 to each other.

さらに前記連結部材６の脚部７、７は、トラフの内壁側に向かって斜めに挿通されるように貫通孔８ａ、８ｂに工夫が施されていて、トラフ用蓋３、３の貫通孔８ａ、８ｂに挿通された連結部材６の脚部７は、その先端部がトラフの内側壁を外向きに押すように作用する。その結果、トラフ用蓋３がより外れ難くなっている、というものである。   Further, the leg portions 7, 7 of the connecting member 6 are devised in the through holes 8a, 8b so as to be inserted obliquely toward the inner wall side of the trough, and the through holes 8a of the trough lids 3, 3 are provided. , 8b, the leg portion 7 of the connecting member 6 acts so that the tip portion pushes the inner wall of the trough outward. As a result, the trough lid 3 is more difficult to come off.

実用新案登録第３０４５８１６号公報Utility Model Registration No. 3045816

しかしながらこの特許文献１に記載の連結部材６の場合、連結部材６の脚部７、７の先端でトラフ内の、例えばケーブル類に傷を付ける危険性がある。特にこの連結部材６を抜け難くしようと脚部７、７の長さを長くすると、その危険性は高まる。かといって脚部７、７の長さを短くすれば、今度は逆に連結部材６が貫通孔８ａ、８ｂから抜け易くなって、このトラフの脇を電車が高速で通過したりした場合に、その風圧でトラフ用蓋３が外れ易くなる、という危険性もある。   However, in the case of the connecting member 6 described in Patent Document 1, there is a risk of scratching, for example, cables in the trough at the tips of the legs 7 and 7 of the connecting member 6. In particular, if the length of the legs 7 is increased so as to make it difficult for the connecting member 6 to come off, the risk increases. However, if the length of the leg portions 7 and 7 is shortened, the connecting member 6 is easily removed from the through holes 8a and 8b, and the train passes through the trough at a high speed. There is also a danger that the trough lid 3 is easily detached by the wind pressure.

しかも実際のトラフにおいては、トラフ内に収納されるケーブルの本数やサイズはまちまちである可能性が高く、さらにはケーブル類がきちんと整列された状態で収納されている場合もあればそうでない場合もあり、脚部７の長さを仮に一定にしたとしても、常にケーブル類を傷つけない、という保証はないのが実情である。   Moreover, in an actual trough, there is a high possibility that the number and size of cables stored in the trough will vary, and the cables may or may not be stored in a properly aligned state. In fact, even if the length of the leg portion 7 is made constant, there is no guarantee that the cables will not always be damaged.

そこで本発明の目的は、トラフ内に収納されているケーブルを傷つける恐れが少なく、しかも蓋同士の連結が容易な、トラフ用蓋、これを連結するトラフ用蓋の連結部材、これらトラフ用蓋やトラフ用蓋の連結部材を用いたトラフ及びトラフへの前記トラフ用蓋の布設方法を提供することにある。   Accordingly, an object of the present invention is to provide a trough lid, a trough lid connecting member for connecting the trough lid, the trough lid connecting member, the trough lid, An object of the present invention is to provide a trough using a connecting member for a trough lid and a method for laying the trough lid on the trough.

図１〜図３は、本発明のトラフ用蓋（以下単に蓋という）の一実施例を示すもので、図１は本発明の蓋同士を、これも本発明のトラフ用蓋の連結部材（以下単に連結部材という）で連結した状態を示す縦断面図、図２は図１に示す連結部材の平面図、そして図３は図１が示す蓋を図２が示す連結部材で連結して、蓋をトラフの開口部に被せた状態を示す斜視図である。   1 to 3 show an embodiment of the trough lid of the present invention (hereinafter simply referred to as a lid). FIG. 1 shows the lids of the present invention, which are also connected to the trough lid of the present invention ( FIG. 2 is a plan view of the connecting member shown in FIG. 1, and FIG. 3 is connected to the lid shown in FIG. 1 with the connecting member shown in FIG. It is a perspective view which shows the state which covered the cover on the opening part of the trough.

図１〜図３では、例えばコンクリート製のトラフ本体２０の上部に開口している開口部２１をトラフ本体長手方向に亘って覆う合成樹脂製の蓋、例えばポリプロピレン、ポリスチレンあるいはポリエチレン等のリサイクル品からなる隣接する２枚の蓋を例に、本発明の一実施例を説明する。
隣接するこの２枚の蓋１０同士が互いに２個の、例えばステンレス製、または金属に溶融亜鉛メッキ加工を施したもの等からなる連結部材３０により連結されている。
因みに、図１が示すようにこの蓋１０は、一端上部に張出部１１を有し、かつ他端下部に隣接する蓋１０の張出部１１の下方に位置決めされる張出受け部１２とを有している。そしてこの蓋１０同士を連結する連結部材３０は、図２が示すようにその上部に蓋１０の張出部１１が挿入される断面略コの字状の張出部差込部３１を有し、かつ下部に前記蓋１０と隣接する蓋１０の他端に設けられている張出受け部１２が挿入される断面略逆コの字状の張出受け部差込部３２を有している。 1 to 3, for example, from a synthetic resin lid that covers the opening 21 that opens at the top of the trough body 20 made of concrete, for example, in the longitudinal direction of the trough body, such as a recycled product such as polypropylene, polystyrene, or polyethylene. An embodiment of the present invention will be described by taking two adjacent lids as an example.
The two adjacent lids 10 are connected to each other by two connecting members 30 made of, for example, stainless steel or a material obtained by subjecting a metal to hot dip galvanizing.
Incidentally, as shown in FIG. 1, the lid 10 has an overhanging portion 11 at one upper end and an overhang receiving portion 12 positioned below the overhanging portion 11 of the lid 10 adjacent to the lower end of the other end. have. And the connection member 30 which connects this lid | covers 10 has the overhang | projection part insertion part 31 of the substantially U-shaped cross section in which the overhang | projection part 11 of the lid | cover 10 is inserted in the upper part, as FIG. 2 shows. In addition, an overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross-section is inserted in the lower portion, into which the overhang receiving portion 12 provided at the other end of the lid 10 adjacent to the lid 10 is inserted. .

ところで連結部材３０に関してコの字状とか逆コの字状という表現を採用しているが、この連結部材３０を逆の方向から見るとコの字状が逆コの字状に見える。それ故、例えば上部に断面略コ字状の張出部差込部を有する、といった場合には、上部の形状がコの字状に見える方向から連結部材３０を見て表現している、というただそれだけの意味である。   By the way, although the expression of U-shape or reverse U-shape is adopted with respect to the connecting member 30, when viewed from the opposite direction, the U-shape looks like an inverted U-shape. Therefore, for example, in the case where the upper portion has an overhanging portion insertion portion having a substantially U-shaped cross section, the connecting member 30 is viewed from the direction in which the upper shape looks like a U-shape. It just means that.

さて、隣接する蓋１０同士を連結する場合には、蓋１０の張出部１１が連結部材３０の断面略コの字状の張出部差込部３１に挿入され、隣接する蓋１０の張出受け部１２が連結部材３０の断面略逆コの字状の張出受け部差込部３２に各々挿入されて互いに隣接する蓋１０同士が相互に連結される。図１、図２の例では連結部材３０の断面略コ字状の張出部差込部３１の高さ方向の間隔が、蓋１０の張出部１１の厚さとほぼ同等か、弱冠それより大きめに設定されており、同様に連結部材３０の断面略逆コ字状の張出受け部差込部３２の高さ方向の間隔が、蓋１０の張出受け部１２の厚さとほぼ同じか、それより弱冠大きめに設計されていて、連結部材３０で連結された蓋１０、１０があまりガタつかない程度に連結される。   When the adjacent lids 10 are connected to each other, the overhanging portion 11 of the lid 10 is inserted into the overhanging portion insertion portion 31 having a substantially U-shaped cross section of the connecting member 30 and the adjacent lid 10 is stretched. The receiving and receiving portions 12 are respectively inserted into the protruding receiving portion insertion portions 32 having a substantially inverted U-shaped cross section of the connecting member 30 so that the adjacent lids 10 are connected to each other. In the example of FIGS. 1 and 2, the distance in the height direction of the overhanging portion insertion portion 31 having a substantially U-shaped cross section of the connecting member 30 is substantially equal to the thickness of the overhanging portion 11 of the lid 10 or less than that. Similarly, whether the interval in the height direction of the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section of the connecting member 30 is substantially the same as the thickness of the overhang receiving portion 12 of the lid 10. The lids 10 and 10 connected to each other by the connecting member 30 are connected to such an extent that they are not so loose.

図３は前述したようにして蓋１０同士を連結部材３０で連結した状態を示している。ここで符号１０ａは案内部材で、蓋１０をトラフ本体２０の開口部２１に被せる際のガイドである。この案内部材１０ａに代えてトラフ本体２０と蓋１０とを、側方からフック等で押えて固定してもよく、それ故この案内部材１０ａは必ずしも必要というわけではない。因みにこの案内部材１０ａは図１では省略している。また図３の手前の蓋１０はトラフ先端の蓋１０ということで、張出受け部１２を設けていないものを使用している。   FIG. 3 shows a state in which the lids 10 are connected by the connecting member 30 as described above. Here, reference numeral 10 a denotes a guide member, which is a guide when the lid 10 is put on the opening 21 of the trough body 20. Instead of the guide member 10a, the trough body 20 and the lid 10 may be fixed by pressing them with a hook or the like from the side. Therefore, the guide member 10a is not always necessary. Incidentally, this guide member 10a is omitted in FIG. Further, the front lid 10 in FIG. 3 is a lid 10 at the tip of the trough, and the one without the overhang receiving portion 12 is used.

ところで図２が示す連結部材３０では、断面略逆コ字状の張出受け部差込部３２の下板を構成する部分の中央付近に切り起し３３が設けられているが、これはこの切り起し３３の先端を蓋１０の下面に食い込ませて、連結部材３０に対して蓋１０の張出受け部１２がガタつかないようにするためのものである。
この切り起し３３は、特に蓋１０の厚さ方向の精度が出難い場合に有効である。もちろん蓋１０の張出受け部１２を含む厚さ方向の精度がきちんと出ている場合には、この切り起し３３は不要である。 By the way, in the connecting member 30 shown in FIG. 2, a cut-up 33 is provided near the center of the portion constituting the lower plate of the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section. The leading end of the cut-and-raised portion 33 is caused to bite into the lower surface of the lid 10 so that the overhang receiving portion 12 of the lid 10 does not rattle with respect to the connecting member 30.
This cut-and-raised 33 is effective particularly when the accuracy of the lid 10 in the thickness direction is difficult to obtain. Of course, when the accuracy in the thickness direction including the overhang receiving portion 12 of the lid 10 has come out properly, this cut-up 33 is unnecessary.

また図２において、符合３４は連結部材３０の同じく断面略逆コ字状の張出受け部差込部３２を構成する下板の先端を内側に折り曲げて形成した折り曲げ部で、この折り曲げ部３４を、切り起し３３同様に蓋１０の下面に食い込ませたり、あるいは蓋１０の下面にリブを設けておいて、そのリブにこの折り曲げ部３４の先端を引っ掛けて、連結部材３０に対して蓋１０の張出受け部１２がガタつかないようにするためのものである。
それ故、この折り曲げ部３４も、蓋１０の張出受け部１２を含む厚さ方向の精度が出ている場合にはあえて設ける必要がないものである。 In FIG. 2, reference numeral 34 is a bent portion formed by bending the tip of the lower plate constituting the extension receiving portion insertion portion 32 of the connecting member 30 having a substantially inverted U-shaped cross section. Is cut into and raised into the lower surface of the lid 10 as in the case of 33, or a rib is provided on the lower surface of the lid 10, and the tip of the bent portion 34 is hooked on the rib to cover the connecting member 30 with the lid. This is to prevent the ten overhang receiving portions 12 from rattling.
Therefore, it is not necessary to provide the bent portion 34 when the accuracy in the thickness direction including the overhang receiving portion 12 of the lid 10 is high.

また図４は、蓋１０の張出部１１や張出受け部１２の厚さの精度が出難い場合の別の対策を示すもので、この連結部材３０は、断面略コ字状の張出部差込部３１及び断面略逆コ字状の張出受け部差込部３２の入口の間隔を、蓋１０の張出部１１や張出受け部１２の厚さより、例えば数ｍｍ程度狭くしておき、これら断面略コ字状の張出部差込部３１や断面略逆コ字状の張出受け部差込部３２に挿入される蓋１０の張出部１１や張出受け部１２を確実に挟持するようにしている。
因みに、この図４が示す連結部材３０にあっては、切り起し３３や折り曲げ部３４は必ずしも必要ではない。しかしながら、これらが揃っていれば張出部１１や張出受け部１２の厚さに大きなばらつきがあっても協働して充分に対応でき好ましい。 FIG. 4 shows another countermeasure when the thickness accuracy of the overhanging portion 11 and the overhanging receiving portion 12 of the lid 10 is difficult to obtain. The connecting member 30 has an overhanging substantially U-shaped cross section. The distance between the inlets of the part insertion part 31 and the extension receiving part insertion part 32 having a substantially inverted U-shaped cross section is made narrower by, for example, several mm than the thickness of the extension part 11 and the extension receiving part 12 of the lid 10. The overhanging portion 11 and the overhanging receiving portion 12 of the lid 10 inserted into the overhanging portion insertion portion 31 having a substantially U-shaped cross section and the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section. Is securely clamped.
Incidentally, in the connecting member 30 shown in FIG. 4, the cut-and-raised portion 33 and the bent portion 34 are not necessarily required. However, it is preferable that these are provided, because even if there are large variations in the thickness of the overhanging portion 11 and the overhanging receiving portion 12, they can sufficiently cope with each other.

また図２や図４において、連結部材３０の断面略コ字状の張出部差込部３１の上板の先端を上部に向かって少し湾曲させて湾曲部を設けているが、これは蓋１０の張出部１１を断面略コ字状の張出部差込部３１に挿入する際、挿入を容易にするために設けたものである。   Further, in FIGS. 2 and 4, the end of the upper plate of the overhanging portion insertion portion 31 having a substantially U-shaped cross section of the connecting member 30 is slightly curved toward the upper portion to provide a curved portion. When the ten overhanging portions 11 are inserted into the overhanging portion insertion portion 31 having a substantially U-shaped cross section, it is provided to facilitate insertion.

ところで、隣接する蓋１０同士を連結部材３０で連結する場合には、例えば最初に連結部材３０の断面略逆コ字状の張出受け部差込部３２に一方の蓋１０の張出受け部１２を挿入し、折り曲げ部３４を蓋１０の下面に設けてあるリブ等に引っ掛けたり、切り起し３３を蓋１０の下面に食い込ませるなどして一方の蓋１０に連結部材３０を予めしっかり装着させておいて、この連結部材３０装着済みの蓋１０を、既にトラフ本体２０上に被せてある蓋１０の張出部１１に向けてスライドさせ、この張出部１１を連結部材３０の断面略コ字状の張出部差込部３１に挿入させ、これを順次繰り返して蓋１０を次々に連結させてもよい。   By the way, when connecting the adjacent lids 10 with the connecting member 30, for example, the overhang receiving portion of one lid 10 is first inserted into the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section of the connecting member 30. 12 is inserted and the bent portion 34 is hooked on a rib or the like provided on the lower surface of the lid 10, or the cut-and-raised 33 is digged into the lower surface of the lid 10. In addition, the lid 10 on which the connecting member 30 has been mounted is slid toward the overhanging portion 11 of the lid 10 that has already been put on the trough main body 20, and the overhanging portion 11 is substantially cut in cross section. It may be inserted into the U-shaped projecting portion insertion portion 31 and this may be repeated sequentially to connect the lids 10 one after another.

図５は本発明の別の実施例を示す縦断面図である。
図５が示す実施例の特徴は、布設環境の変化、特に温度変化で合成樹脂製の蓋１０が膨張し、膨張した部分が逃げ場を失って、蓋１０がトラフ本体２０から飛び出すことのないように工夫されている点にある。
具体的には、連結部材３０の断面略コ字状の張出部差込部３１の奥の面と、この断面略コ字状の張出部差込部３１に差し込まれた蓋１０の張出部１１の先端との間に、例えば蓋１０の長さの０．１％〜５％になるような長さの隙間３８ができるように、同様に連結部材３０の断面略逆コ字状の張出受け部差込部３２を構成する板の裏面から隣接する蓋１０の張出部１１の起点からの隙間３９も蓋１０の長さの０．１％〜５％の長さになるように蓋１０と連結部材３０の各寸法が決められている。 FIG. 5 is a longitudinal sectional view showing another embodiment of the present invention.
The characteristic of the embodiment shown in FIG. 5 is that the cover 10 made of synthetic resin expands due to a change in the laying environment, in particular, a temperature change, and the expanded portion loses the escape place so that the cover 10 does not jump out of the trough body 20. It is in the point devised by.
Specifically, the rear surface of the overhanging portion insertion portion 31 having a substantially U-shaped cross section of the connecting member 30 and the extension of the lid 10 inserted into the overhanging portion insertion portion 31 having a substantially U-shaped cross section. Similarly, the cross-section of the connecting member 30 is substantially reverse U-shaped so that a gap 38 having a length of, for example, 0.1% to 5% of the length of the lid 10 is formed between the leading end of the protruding portion 11. The gap 39 from the starting point of the overhanging portion 11 of the lid 10 adjacent to the back surface of the plate constituting the overhang receiving portion insertion portion 32 is also 0.1% to 5% of the length of the lid 10. Thus, the dimensions of the lid 10 and the connecting member 30 are determined.

前記隙間３８や隙間３９を所定の間隔にするために、図５が示すように連結部材３０の断面略コ字状の張出部差込部３１を構成する板の先端に下向きの突起３６を設け、さらに蓋１０の上面に位置規制用突起１３、１４を設けてある。すなわち、常温では前記突起３６が蓋１０に設けた位置規制用突起１３、１４の間に位置決めされる。もし温度が上がって蓋１０が膨張した場合には、突起３６が位置規制用突起１３を乗り越える。その結果、蓋１０の膨張分は隙間３８、３９に吸収され、蓋１０同士が膨張して逃げ場を失ってトラフ本体２０から持ち上がることがなくなる。
尚、位置規制用突起１３は必ずしも必要でないが、位置規制用突起１３があった方が常温時、連結部材３０ががたつくことがなく好ましい。
この図５に示すものは、温度変化が大きい場所に布設されるトラフには最適である。因みに、温度変化の少ない環境下に布設されるものにはあえてこの種の位置規制用突起１３、１４を設ける必要はない。 In order to set the gap 38 and the gap 39 to a predetermined interval, as shown in FIG. 5, a downward projection 36 is formed at the tip of the plate constituting the protruding portion insertion portion 31 having a substantially U-shaped cross section of the connecting member 30. Further, the position restricting projections 13 and 14 are provided on the upper surface of the lid 10. That is, the projection 36 is positioned between the position regulating projections 13 and 14 provided on the lid 10 at room temperature. If the temperature rises and the lid 10 expands, the protrusion 36 gets over the position restricting protrusion 13. As a result, the expansion of the lid 10 is absorbed by the gaps 38 and 39, so that the lids 10 will not expand and lose their escape and will not lift from the trough body 20.
Although the position restricting protrusion 13 is not necessarily required, it is preferable that the position restricting protrusion 13 is provided because the connecting member 30 is not struck at room temperature.
The one shown in FIG. 5 is optimal for troughs laid in places where the temperature change is large. Incidentally, it is not necessary to provide this kind of position restricting projections 13 and 14 for an object installed in an environment with little temperature change.

図６は本発明のさらにまた別の実施例を示すもので、その特徴は、蓋１０の張出受け部１２の形状にある。前述した実施例のものでは、蓋１０の連結部の隙間から雨水等がトラフ本体２０内に侵入する恐れがあるが、図６に示す実施例のものはこの雨水等外部からの水の侵入を防止するような改良を加えたものである。因みに、図６（ａ）は蓋１０の一部平面図、図６（ｂ）は正面図である。   FIG. 6 shows still another embodiment of the present invention, which is characterized by the shape of the overhang receiving portion 12 of the lid 10. In the embodiment described above, rainwater or the like may enter the trough body 20 from the gap between the connecting portions of the lid 10, but the embodiment shown in FIG. This is an improvement that prevents it. 6A is a partial plan view of the lid 10, and FIG. 6B is a front view.

図６が示す蓋１０の特徴は、蓋１０の張出受け部１２の先端に水侵入防止突起１７を設け、かつこの張出受け部１２の断面形状を頂部１６を有する屋根型にし、蓋１０同士の連結部の隙間から侵入した水が張出受け部１２の先端方向からトラフ本体２０の内部に流れずに、屋根型の斜面を伝ってトラフ本体２０の側壁の外側に流れるようにした点にある。
因みに、この屋根型の部分の角度は、例えば０．００１度以上、好ましくは数度程度にするのが好ましい。あまり角度を大きくすると、連結部材３０の断面略逆コ字状の張出受け部差込部３２にこの張出受け部１２を差し込んだ際、両者の隙間が大きくなってがたつきが大きくなってしまうからである。尚、屋根型の斜面を伝って流れ落ちた水がトラフ本体２０内に流れ込まないように、張出受け部１２の両端はトラフ本体２０の側壁の外側に位置するように設計されている。 The lid 10 shown in FIG. 6 is characterized in that a water intrusion preventing projection 17 is provided at the tip of the overhang receiving portion 12 of the lid 10, and the cross section of the overhang receiving portion 12 is a roof type having a top portion 16. Water that has entered through the gap between the connecting portions does not flow into the trough body 20 from the front end direction of the overhang receiving portion 12, but flows to the outside of the side wall of the trough body 20 through the roof-shaped slope. It is in.
Incidentally, the angle of the roof-shaped portion is, for example, 0.001 degrees or more, preferably about several degrees. If the angle is increased too much, when the overhang receiving portion 12 is inserted into the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section of the connecting member 30, the gap between the both becomes large and the rattling becomes large. Because it will end up. It should be noted that both ends of the overhang receiving portion 12 are designed to be located outside the side wall of the trough body 20 so that water that has flowed down along the roof-shaped slope does not flow into the trough body 20.

図７、図８は本発明の連結部材３０の別の実施例を示すものである。この連結部材３０の特徴は、断面略コ字状の張出部差込部３１と断面略逆コ字状の張出受け部差込部３２の中間部に仕切り板４０を溶接等により形成し、仕切り区間４１を設けた点にある。
因みに、図７が示すものは単に１枚の仕切り板４０を連結部材３０の中間位置に溶接したもの、図８が示すものは、断面略コ字状の張出部差込部３１と仕切り区間４１が形成されたものに、断面略逆コ字状の張出受け部差込部３２のみ形成された部材を面溶接したものである。
これらの連結部材３０は、蓋１０の全体の厚さに対して張出部１１と張出受け部１２の合計厚さが比較的小さい場合に用いるもので、このように連結部材３０の中間部に仕切り板４０を設けることで、断面略コ字状の張出部差込部３１に張出部１１を、断面略逆コ字状の張出受け部差込部３２に張出受け部１２をがたつきなく差し込み、保持することができる。 7 and 8 show another embodiment of the connecting member 30 of the present invention. The connecting member 30 is characterized in that a partition plate 40 is formed by welding or the like at an intermediate portion between an overhanging portion insertion portion 31 having a substantially U-shaped cross section and an overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section. The point is that the partition section 41 is provided.
Incidentally, FIG. 7 shows only one partition plate 40 welded to the intermediate position of the connecting member 30, and FIG. 8 shows an overhang portion insertion portion 31 having a substantially U-shaped cross section and a partition section. 41 is formed by surface welding a member in which only the overhang receiving portion insertion portion 32 having a substantially inverted U-shaped cross section is formed.
These connecting members 30 are used when the total thickness of the overhang portion 11 and the overhang receiving portion 12 is relatively small with respect to the entire thickness of the lid 10, and thus the intermediate portion of the connecting member 30. By providing the partition plate 40, the overhanging portion 11 is provided in the overhanging portion insertion portion 31 having a substantially U-shaped cross section, and the overhang receiving portion 12 is provided in the overhang receiving portion insertion portion 32 having a substantially reverse U-shaped cross section. Can be inserted and held without rattling.

ところで本発明の連結部材３０を用いて、トラフ本体２０の開口部２１を蓋１０で塞いでいった場合、ある箇所で数個の蓋１０を開かねばならないとき、どのように蓋１０を開くかが問題になる。そのような場合、予め蓋１０を例えば５個くらいを一組にして、隣接する組同士の連結には、連結部材１０に代えて図９が示すように、断面略Ｌ字状の連結具５０を用いて、隣接する蓋１０同士を側面方向から連結する方法がある。
このようにしておけば、トラフ本体２０内のケーブルに問題が起こったら、その問題が起こった近くの連結具５０を外して、一組または二組の蓋１０、すなわち５〜１０個の蓋１０を順次外せばよい。 By the way, when the opening part 21 of the trough body 20 is closed with the lid 10 using the connecting member 30 of the present invention, how to open the lid 10 when several lids 10 must be opened at a certain position. Is a problem. In such a case, for example, about five lids 10 are set in advance, and for connecting adjacent groups, as shown in FIG. There is a method of connecting the adjacent lids 10 from the side surface direction using.
In this way, if a problem occurs in the cable in the trough body 20, the nearby connector 50 where the problem has occurred is removed, and one or two sets of lids 10, that is, five to ten lids 10 are provided. Should be removed sequentially.

ところで蓋１０の材料としては、例えば、ポリエチレン樹脂、ポリプロピレン樹脂、ポリスチレン樹脂あるいはこれらのリサイクル品が利用できる。また連結部材３０としては、これが風雨に晒されるものであることを鑑み、ステンレス製とかプラスチック製あるいはメッキを施した金属製であることが好ましい。特に蓋１０の張出部１１や張出受け部１２を長期に亘って把持しなければならないことを考えると、ステンレス製であることが好ましい。
また隣接する蓋１０同士を連結部材３０で連結する場合には、図３が示すように蓋１０の幅方向の両側、すなわち２箇所で連結するのが一般的であるが、蓋１０の幅が狭いものなら１箇所でもよいし、逆に幅の広い蓋１０同士を連結する場合には、２箇所以上でもよいし、幅の広い連結部材３０を用いてもよい。蓋１０の幅や布設される環境条件を考慮して連結部材３０の個数及び寸法を決めればよい。 By the way, as a material of the lid | cover 10, a polyethylene resin, a polypropylene resin, a polystyrene resin, or these recycled products can be utilized, for example. The connecting member 30 is preferably made of stainless steel, plastic, or plated metal in view of the fact that it is exposed to wind and rain. In particular, considering that the overhanging portion 11 and the overhanging receiving portion 12 of the lid 10 must be gripped over a long period of time, it is preferably made of stainless steel.
Further, when the adjacent lids 10 are connected by the connecting member 30, as shown in FIG. 3, it is generally connected at both sides in the width direction of the lid 10, that is, at two locations. If it is narrow, it may be one place. Conversely, when connecting the wide lids 10 to each other, two or more places may be used, or a wide connecting member 30 may be used. The number and dimensions of the connecting members 30 may be determined in consideration of the width of the lid 10 and the installed environmental conditions.

以上述べたように本発明によれば、トラフ内に収納されているケーブルを傷つける恐れが少なく、しかも蓋同士の連結が容易な、トラフ用蓋、これを連結するトラフ用蓋の連結部材、これらトラフ用蓋やトラフ用蓋の連結部材を用いたトラフ及びトラフへの前記トラフ用蓋の布設方法を提供ができる。   As described above, according to the present invention, there is little risk of damaging the cable housed in the trough, and the lid for the trough that is easy to connect between the lids, the connecting member for the trough lid for connecting the lid, these It is possible to provide a trough using a trough lid or a trough lid connecting member and a method for laying the trough lid on the trough.
