Description
【０００１】[0001]
この考案は電線共同溝に関するもので、特に、複数個のプレキャストコンクリ ートブロックで電線共同溝を作成するとき、各ブロックを埋設するときに、それ らを整列させるガイドを有するとともに、連設した電線挿通溝の内周面に凹凸が なくて電線が挿通し易く、かつ、損傷することのないようにしたものである。 This invention relates to an electric wire common groove, and in particular, when a plurality of precast concrete blocks are used to form the electric wire common groove, and when each block is embedded, it has a guide for aligning them and the continuous wire insertion The inner surface of the groove has no irregularities so that the wire can be easily inserted and is not damaged.
【０００２】[0002]
市街地等の上空に張り巡らせた電力線や電話線その他等の電線の猥雑性をなく するために、これらをまとめて地中に埋設する環境美化運動が隆盛し、従来より 市街地等の道路に溝を開削し、該溝中に現場打ちコンクリートにより電線共同溝 が作られて来た。 In order to eliminate the messiness of electric wires such as power lines, telephone lines, etc., which have been stretched over the city and other areas, the environmental beautification movement to bury them all together has been prosperous, and trenches have been created on roads such as city areas. After excavation, a joint groove for electric wires has been created in the groove by cast-in-place concrete.
【０００３】 しかしながら、現場打ちコンクリートによる電線共同溝の作成は、施工期間が 長くて交通の支障を来たすために、予め工場生産されたプレキャストコンクリー トブロックの複数個を現場へ輸送し、これらを現場で連設施工して共同溝を作成 することが迅速性があるといえる。However, since the construction of the electric wire joint groove using cast-in-place concrete takes a long construction period and causes an obstacle to traffic, a plurality of precast concrete blocks produced in advance at the factory are transported to the site, and these are delivered to the site. It can be said that it is expeditious to construct joint grooves by constructing them in series.
【０００４】 しかし、プレキャストコンクリートブロックを埋設施工する場合に、各ブロッ クが整列して一直線状に連設されなければ、施工の見栄えが悪いばかりでなく、 電線を挿通する溝の内周面に凸凹が形成され、その凸部に電線が摺接して挿通の 支障となったり、若しくは電線が擦過により損傷する。However, when the precast concrete blocks are buried, if the blocks are not aligned and continuously arranged in a straight line, not only does the appearance look bad, but also the inner peripheral surface of the groove through which the electric wire is inserted. Unevenness is formed, and the electric wire slides on the convex part to hinder the insertion, or the electric wire is damaged by abrasion.
【０００５】 しかしながら、従来、このような不都合を解決できる電線共同溝は、未だ提供 されていない。However, hitherto, a wire joint groove capable of solving such inconvenience has not been provided yet.
【０００６】[0006]
そこで、この考案はプレキャストコンクリートブロックによる共同溝の敷設に 際し、連設するプレキャストコンクリートブロックの整列施工を簡便迅速かつ容 易に実現できるとともに、電線挿通の支障を来すことなく、かつ、電線が擦過し て損傷することのない電線共同溝を提供する。 Therefore, this invention makes it possible to easily and quickly and easily align the precast concrete blocks that are to be installed consecutively when laying a common groove with the precast concrete blocks, and without causing any trouble in inserting the wires. Provides a common wire groove that will not be scratched and damaged.

この考案にかかる電線共同溝は、透孔を有する筒状に形成したプレキャストコ ンクリートブロックであって、前記透孔の両端部内周面側にそれぞれ所定長さの 凹部を形成し、該凹部の深さと略同一の肉厚を有する所定長さの筒体を連設のガ イドを兼ねて嵌合し接続することを特徴とする。 The wire joint groove according to the present invention is a cylindrical precast concrete block having a through hole, and a recess of a predetermined length is formed on each of the inner peripheral surfaces of both ends of the through hole. It is characterized in that a cylindrical body of a predetermined length having substantially the same wall thickness is fitted and connected while also functioning as a continuous guide.
【０００８】 そして、前記筒体は、鋼管又は、プラスチック管又は、複合材からなることを 特徴とする。The cylindrical body is made of a steel pipe, a plastic pipe, or a composite material.
【０００９】[0009]
以下この考案を図に示す実施の形態に基づき説明する。図１に示すように、所 定長さの筒状又は管状に形成されたプレキャストコンクリートブロック１（以下 単にブロック１と略）の複数個を、電線を挿通すべき透孔２に互いに嵌合する筒 体３を介して連設する。すなわち、図２に示すブロック１の単体を互いに筒体３ をガイドとして所要長さの電線共同溝を連設するに際し、複数個のブロック１の 整列性を確保するものである。 The invention will be described below based on the embodiment shown in the drawings. As shown in FIG. 1, a plurality of precast concrete blocks 1 (hereinafter, simply referred to as block 1) formed in a tubular shape or a tubular shape having a predetermined length are fitted into the through holes 2 through which electric wires are to be inserted. It is connected continuously through the cylindrical body 3. That is, when the single unit of the block 1 shown in FIG. 2 is continuously provided with the electric wire common groove of a required length by using the tubular body 3 as a guide, the alignment of the plurality of blocks 1 is ensured.
【００１０】 透孔２はその両端部にそれぞれ筒体３を嵌合するための凹部４を有する。凹部 ４は透孔２の内周面側に形成され、しかも、筒体３の肉厚分の深さを有する。筒 体３は鋼管、プラスチック管又は複合材料からなる管体である。複合材料は、例 えば鋼管に合成樹脂を塗覆したものなどからなる。したがって、筒体３を透孔２ に嵌合した場合に、透孔２と筒体３の内周面とは同一面に形成されるため、凸凹 がなくて電線を挿通し易く、かつ、電線が擦過して損傷することがない。The through hole 2 has recesses 4 at both ends thereof for fitting the tubular body 3, respectively. The recess 4 is formed on the inner peripheral surface side of the through hole 2 and has a depth corresponding to the thickness of the cylindrical body 3. The tubular body 3 is a steel tube, a plastic tube, or a tube made of a composite material. The composite material is, for example, a steel pipe coated with a synthetic resin. Therefore, when the tubular body 3 is fitted in the through hole 2, the through hole 2 and the inner peripheral surface of the tubular body 3 are formed on the same surface, so that there is no unevenness and the electric wire can be easily inserted, and the electric wire can be inserted. Will not be scratched and damaged.
【００１１】 なお、ブロック１の断面形状は円形でも四角形でもよく、また、透孔２及び筒 体３の断面形状は円形でも四角形でもよい。The cross-sectional shape of the block 1 may be circular or square, and the cross-sectional shape of the through hole 2 and the cylinder 3 may be circular or square.
【００１２】 そして、上記ブロック１の複数個を連設するときは、一端部側の透孔２の凹部 ４に筒体３を嵌合し、その筒体３に他のブロック１の一端部側の透孔２における 凹部４を嵌合してブロック１，１の間隙がなくなるように両者を緊締する作業を 繰り返せば、複数個のブロック１，１，…の整列性が確保されるというものであ る。When a plurality of the blocks 1 are arranged in series, the tubular body 3 is fitted into the recess 4 of the through hole 2 on the one end side, and the tubular body 3 is fitted to the one end side of the other block 1. By repeating the work of fitting the recesses 4 in the through holes 2 and tightening the two so that the gap between the blocks 1 and 1 is eliminated, the alignment of the plurality of blocks 1, 1, ... Is assured. is there.
【００１３】 かくして、透孔２と筒体３とで電線を挿通する溝を形成するのであるから、筒 体３と透孔２との結合には適宜の充填材を用いてシールすることが望ましいのは 勿論のこと、電線共同溝として必要な棚や仕切体を設けることも自由である。Thus, since the through hole 2 and the tubular body 3 form a groove through which an electric wire is inserted, it is desirable to seal the tubular body 3 and the through hole 2 by using an appropriate filler. Needless to say, it is also possible to install shelves and partitions that are necessary for electric wire joint grooves.
【００１４】 したがって、各ブロックの連設施工の見栄えが良好となるばかりでなく、透孔 ２と筒体３との内周面が同一面に形成されるために、凸凹がなくて電線を挿通す る場合に支障したり、電線を損傷させる不都合を生じない。Therefore, not only is the appearance of the continuous construction of each block improved, but since the inner peripheral surfaces of the through hole 2 and the cylindrical body 3 are formed on the same surface, there is no unevenness and the electric wire can be inserted. It does not cause any inconvenience when passing the cable or damage the wires.

以上説明したこの発明によれば、筒状に形成されたプレキャストコンクリート ブロックの透孔の両端部に内周面が同一面となる筒体を嵌合する凹部を形成し、 該凹部に筒体を嵌合してこれを連設すべき他のプレキャストコンクリートブロッ クの透孔に嵌合させることにより、電線共同溝の整列施工が確保されるから、施 工の見栄えが向上するほか、電線を挿通すべき溝が面一になり凹凸が形成されな いので、電線挿通の作業性を向上させるとともに、電線が擦過して損傷すること がない。 According to the present invention described above, a recess is formed at each end of a through hole of a precast concrete block formed in a tubular shape, into which a tubular body having the same inner peripheral surface is fitted, and the tubular body is provided in the recess. By fitting and fitting this into the through holes of other precast concrete blocks that should be connected in series, the alignment of the wire joint groove can be secured, which improves the appearance of the work and also allows the wire to be inserted. Since the groove to be passed is flush and no irregularities are formed, the workability of inserting the wire is improved and the wire is not scratched and damaged.
