【発明の詳細な説明】
本発明は、送電ケーブルを洞道内に布設する際、使用す
るトラフの組立が従来のものより容易且つ迅速に行われ
、作業性を向上できるように改良したものである。DETAILED DESCRIPTION OF THE INVENTION The present invention has been improved so that when laying a power transmission cable in a tunnel, the trough used can be assembled more easily and quickly than in the past, improving work efficiency. .
即ち本発明は、限定された長さの樋状を呈するトラフ本
体を洞道内で継ぎ合せて内部にケーブルを設置した後、
一端側を約肉厚分に相当するだけ狭めて形成されだ嵌合
部を有する、はソ同−巾の樋状蓋と本体の双方の側縁部
を向い合せて閉じるに際し、蓋の全側縁と嵌合部の側縁
が、同時に挿入できるに充分な内法を有する一定断面の
連続した挿入溝を、本体の両側縁部先端に一体に設ける
ことを特徴としたものである。That is, in the present invention, after the trough bodies exhibiting a trough shape of limited length are joined together in a tunnel and a cable is installed inside,
It has a fitting part formed by narrowing one end side by an amount corresponding to the wall thickness, and when closing the side edges of both the gutter-like lid and the main body of the same width, the entire side of the lid can be closed. The device is characterized in that continuous insertion grooves with a constant cross section, which have a sufficient internal diameter to allow the edges and the side edges of the fitting portion to be inserted simultaneously, are integrally provided at the tips of both side edges of the main body.
この発明は、洞道内でのトラフ組立作業を極めて容易と
し作業性を飛躍的に向上させるものである。This invention makes it extremely easy to assemble a trough inside a tunnel, dramatically improving work efficiency.
本発明を添附図面によって更に具体的に説明する。The present invention will be explained in more detail with reference to the accompanying drawings.
第１図は典型例を説明するための斜視図、第２図は断面
説明図である。FIG. 1 is a perspective view for explaining a typical example, and FIG. 2 is an explanatory cross-sectional view.
１は一定断面の樋状の強化プラスチック製本体で、両側
縁部に上方に開口した挿入溝２が一体で成形されている
。Reference numeral 1 denotes a gutter-shaped reinforced plastic main body with a constant cross section, and insertion grooves 2 that open upward are integrally molded on both side edges.
本体１と隣接する別の本体１′の端面同志突合せ、別に
準備したソケット３を継目の外側よりかぶせて、リベッ
ト又はボルトで固定し、この操作を繰返して連続した長
尺の樋状ケーブル受けを洞道内に形成させる。The end faces of main body 1 and another adjacent main body 1' are butted together, a separately prepared socket 3 is placed over the joint from the outside, and fixed with rivets or bolts, and this operation is repeated to form a continuous long gutter-shaped cable receiver. Formed within the sinus tract.
次で、この中にケーブルその他必要な部品を設置する。Next, install cables and other necessary parts inside this.
ソケット３は、本体の一端部に予め固定したものを準備
し、洞道内で隣接する本体の別の端部と接合してもよい
。The socket 3 may be fixed in advance to one end of the main body and joined to another end of the adjacent main body within the sinus canal.
樋状蓋４は一端側部に蓋の肉厚に相当する高さ分狭めて
一体に成形した嵌合部５を有し、素材は強化プラスチッ
ク製である。The gutter-like lid 4 has a fitting part 5 formed integrally with the fitting part 5 narrowed by a height corresponding to the thickness of the lid at one end thereof, and is made of reinforced plastic.
第１図に示すように、トラフ本体の最端部より、蓋の両
側縁を本体の挿入溝に対向させて挿入する。As shown in FIG. 1, the lid is inserted from the extreme end of the trough body with both side edges facing the insertion grooves of the body.
本体の溝２の内法は第２図に示すように蓋と嵌合部の側
縁が挿入できるに充分な１］を有しており、作業は極め
て容易である。As shown in FIG. 2, the inner diameter of the groove 2 of the main body has a sufficient diameter 1 to allow the side edges of the lid and the fitting part to be inserted, making the operation extremely easy.
次に別の蓋４′を、蓋４に隣接して、同様の操作で、本
体に合着させる。Next, another lid 4' is attached to the body adjacent to lid 4 in a similar manner.
この際隣設される蓋４′の、嵌合部の反対側の端側部を
先に設置せる蓋４の嵌合部５の部分に重ねて、側縁部を
本体の溝に挿入する。At this time, the end side opposite to the fitting part of the adjacent lid 4' is overlapped with the fitting part 5 of the lid 4 to be installed first, and the side edge part is inserted into the groove of the main body.
嵌合部５は、蓋のはソ肉厚に相当する高さの段差がある
ので、５の側縁と本体溝を構成する内壁間には、次で挿
入される蓋４′の側縁が挿入されるに充分の隙間が確保
されている。Since the fitting part 5 has a height difference corresponding to the thickness of the lid, the side edge of the lid 4' to be inserted next is between the side edge of the fitting part 5 and the inner wall constituting the main body groove. Sufficient clearance is provided for insertion.
この発明の有利な点は、第１図に示したように、本体と
蓋の継目が必ずしも一致する必要がない点である。An advantage of this invention is that the seams between the body and the lid do not necessarily have to coincide, as shown in FIG.
すなわち本体の継目部分の溝は互に対向した状態で固定
され、断面がはソ一致しているので蓋の側縁部が、本体
同志の継目を１だいで楽に挿入できる点が特徴である。In other words, the grooves at the joints of the main bodies are fixed opposite each other, and the cross-sections are identical, so the side edges of the lid can be easily inserted into the joints of the main bodies in one go.
この点は非常に重要な意味を持つものである。This point has a very important meaning.
すなわち、すでに知られている実公昭４５−２２４４２
号公報に記載のケーブル布設用トラフの様に、蓋と本体
の継目が一致しなければ接続できない場合に比べ、継目
を合せるために蓋か本体のどちらかを切断しなければな
らないと云う、材料と時間の無駄がなく、本体の継目に
気をつかうことなく組立てることができ、洞道内での作
業時間を大巾に短縮することを可能とするものである。In other words, the already known Utility Model Publication No. 45-22442
Compared to cases where the cable laying trough described in the above publication cannot be connected unless the joints between the lid and the main body match, the material requires cutting either the lid or the main body to match the joints. This eliminates wasted time and allows assembly without worrying about the joints of the main body, making it possible to significantly shorten the working time inside the tunnel.
第１図では、蓋の嵌合部を狭めて成形した場合を示した
が、嵌合部を肉厚分だけ拡げて段差をつけた場合も、組
立作業は同様に進行する。Although FIG. 1 shows the case where the fitting portion of the lid is narrowed and molded, the assembly work proceeds in the same way if the fitting portion is widened by the thickness and a step is formed.
すなわちこの場合は、隣接する蓋の嵌合部を先に合着さ
せた蓋の嵌合部のない端面上に重ねて合着すればよい。That is, in this case, the fitting portions of adjacent lids may be overlapped and bonded onto the end surfaces of the previously bonded lids that do not have the fitting portions.
本体は両側縁に溝を有する複雑な一定断面の長尺構造体
であるので、引抜成形法で成形するのが有利であるが、
第３図のように金型から脱着できる断面でプレス成形す
ることも可能である。Since the main body is a long structure of a complex constant cross section with grooves on both sides, it is advantageous to mold it by pultrusion.
It is also possible to perform press molding with a cross section that can be removed from the mold as shown in FIG.
蓋は嵌合部をプレス成形で一体で成形するか、または引
抜法で成形した蓋に予め準備した嵌合部材を接着または
リベット等で接着して製造することもできる。The lid can also be manufactured by integrally molding the fitting portion by press molding, or by adhering a previously prepared fitting member to the lid formed by a pultrusion method with adhesive or rivets.

、防災トラフ用として実用化されている。It is desirable to impart flame retardancy to the resin that makes up the material.One way to make unsaturated polyester resin, which is generally used for reinforced plastics, flame retardant is to add chlorine, bromine, etc.
・Achieved by containing chlorogen molecules in the structure or by secondary inclusion of water-use alumina, powder, chlorinated paraffin, antimony trioxide, etc., and those with an oxygen index of 47 or more have been put into practical use for disaster prevention troughs. There is.
蓋の合着作業が終了した後は、ベルト６または紐で本体
