明 細 耆 フレキシプルパイプの製造方法 技術分野 Akira Hosoki Flexible Pipe Manufacturing Method Technical Field
本発明は、 例えば 锒や光ファイバを敷設するときに好適に用いることができ るフレキシブルパイプの製造方法に関する。 冃景. 技術 The present invention relates to a method for manufacturing a flexible pipe that can be suitably used, for example, when laying an optical fiber.冃 景. Technology
フレキシブルパイプは可撓性があるので酉 B/線の作業性に富み、 また、 パイプ内 部に収納したものを外力から保護できる。 そこで、 従来からフレキシブルパイプ は、 m /線や光ファイノく等を敷設する際の保護管として広く使用されている。 しか し、 電線が敷設される長さは数キロ以上にも及ぶ があり、 敷設現場でフレキ シブルパイプ内に 锒を揷通させることは極めて困難であった。 Since the flexible pipe is flexible, the work of the rooster B / wire is rich, and the one stored inside the pipe can be protected from external force. Therefore, flexible pipes have been widely used as protection pipes for laying m / wires, optical fins, and the like. However, the length of the electric wires laying several kilometers or more, it was extremely difficult to penetrate the flexible pipes at the laying site.
そこで、 従来においてはメッセンジャ或いはリード線と称される針金を先ずフ レキシブルパイプ内に通して、 これを案内に電線等をフレキシブルパイプ内に揷 通させる作業力 s行われている。 図 1は、 この挿通作業の様子を示した図である。 フレキシブルパイプ 1 0 0内に、 先ずリード線として針金 1 0 1が揷通される。 針金 1 0 1は 锒ゃ光ファイバよりも岡 ij性があるので、 比較的容易にフレキシブ ルパイプ内を真っ直ぐに進入させることができる。 この針金 1 0 1の終端には例 えば 線 1 0 5を引っ掛けるフック 1 0 2が固定されている。 よって、 針金 1 0 1をフレキシブルパイプの右側から順次、 弓 I出せばフレキシブルパイプ 1 0 0内 に電線 1 0 5を揷通できる。 Therefore, conventionally, a wire called a messenger or a lead wire is first passed through a flexible pipe, and the guide wire guides a wire or the like through a flexible pipe. FIG. 1 is a diagram showing this insertion work. First, a wire 101 is passed through the flexible pipe 100 as a lead wire. Since the wire 101 has a higher ij property than the optical fiber, it can relatively easily enter the flexible pipe straight. At the end of the wire 101, for example, a hook 102 for hooking a wire 105 is fixed. Therefore, the wire 105 can be passed through the flexible pipe 100 by sequentially passing the wire 101 from the right side of the flexible pipe to the bow I.
上記のようにフレキシブルパイプ 1 0 0内に電線を挿通させる作業は、 電線を 敷設する現場において行うことも可能である。 し力 し、 敷設現場での作業はより 効率化することが望ましい。 そこで、 リード線となる針金 1 0 1を予め揷通させ たフレキシブルパイプが供給されるようになっている。 The operation of inserting an electric wire into the flexible pipe 100 as described above can also be performed at a site where the electric wire is laid. However, it is desirable that work on the construction site be more efficient. Therefore, a flexible pipe in which a wire 101 serving as a lead wire is passed in advance is supplied.
しかしながら、 上記のように針金等のリ一ド線が予め揷通されたフレキシブル パイプを提供するには、 フレキシブルパイプを製造した後にリ一ド線を揷通させ る工程をさらに設ける必要がある。 また、 フレキシブルパイプには直径が十数ミ リとレ、う管径の細レヽものも有り、 このような狭小なフレキシブノレパイプの:^に はリード線を揷通させる工程自体を確立するのが困難となる。 However, as described above, in order to provide a flexible pipe through which a lead wire such as a wire is previously passed, it is necessary to pass the lead wire after manufacturing the flexible pipe. It is necessary to provide a further step. In addition, there are flexible pipes with diameters of more than ten millimeters and small diameter pipes. For such narrow flexible pipes, the process of passing the lead wire is established. Becomes difficult.
本発明は、 前述した従来における を解決し、 内部にリード線等の線材を容 易に挿通させることができるフレキシブノレパイプの製造方法を ^することであ る。 発明の開示 An object of the present invention is to provide a method for manufacturing a flexi-nole pipe in which the above-described conventional method can be solved and a wire such as a lead wire can be easily inserted therein.

By removing the shaft from the manufactured flexible pipe, it becomes possible to drop the upper ia material into the pipeline, so simply changing the conventional flexible pipe manufacturing process can reduce the wire material. It will be possible to manufacture flexible pipes that pass through.

Further, when this wire is used as a wire or an optical fiber, these wires can be passed through without using leads and wires. In addition, the lift self-length material can be formed using a metal plate. BRIEF DESCRIPTION OF THE FIGURES

以下、 図面に基づレ、て本発明の一実施形態に係るフレキシブノレパイプにつレ、て 説明する。 図 2は、 本フレキシブルパイプを作製するのに用いる長尺部材を例示 した図である。 図 2 (A) は長尺部材 1を正面から見た図、 （B) は （A) におけ る A— A断面を示した図である。 長尺部材 1としては、 例えばアルミ等の金属板 を数ミリ ¾ の薄板に形成したものを （B) に示すように横断面が S字状となる ように加工したものを好適に用いることができる。 Hereinafter, a flexible pipe according to an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a diagram exemplifying a long member used for manufacturing the present flexible pipe. FIG. 2 (A) is a view of the long member 1 as viewed from the front, and FIG. 2 (B) is a view showing an A-A section in FIG. 2 (A). As the long member 1, for example, a metal plate made of a metal plate such as aluminum formed into a thin plate of several millimeters and processed so as to have an S-shaped cross section as shown in (B) is preferably used. it can.
図 3は、 上記長尺部材 1をシャフトに螺旋状に卷付ける様子を、 断面で示した 図である。 図 3では長尺部材 1を下に向かって螺 状に卷付ける様子を示してい る。 長尺部材 1は左 1 _ 1位置から下方に下がりながら右の 1一 2位置でシャフ ト 5に卷付けられる。 さらに、 右 1 _ 2の位置から下方に下がりながら左の 1— 3位置でシャフト 5に卷付けられる。 そして、 左 1一 3位置から下方に下がりな がら右の 1一 4位置でシャフト 5に卷付けられる。 FIG. 3 is a cross-sectional view showing a state where the long member 1 is spirally wound around a shaft. FIG. 3 shows a state in which the long member 1 is spirally wound downward. The long member 1 is wound around the shaft 5 at the right position 112 while descending from the left position 1-1. Further, it is wound around the shaft 5 at the left 1-3 position while descending downward from the right 1-2 position. Then, it is wound around the shaft 5 at the right position 114 while descending downward from the left position 113.
この図 3で、 1—1位置の長尺部材 1の下部と 1— 3位置の長尺部材 1の上部 との一部が重なるように、 同様に 1一 2位置の長尺部材 1の下部と 1— 4位置の 長尺部材 1の上部との一部が重なるように、 順次卷付けを行えばシャフト 5を取 除レ、たときに内部に管路が形成される。 In Fig. 3, the lower part of the long member 1 at the 1-2 position is also set so that the lower part of the long member 1 at the 1-1 position and the upper part of the long member 1 at the 1-3 position overlap. If winding is performed sequentially so that a part of the upper part of the long member 1 at positions 1 to 4 overlaps, the shaft 5 is removed and a pipe is formed inside when the shaft 5 is removed.
ところで、 上記のように上に位置した長尺部材 1 ( 1 - 1位置或レ、は 1— 2位 置にあるもの） の下部に下側に位置した長尺部材 1 ( 1 - 3位置或！/、は 1— 4位 置にあるもの） の上部を重ねるときに、 下側に少しオフセットさせることで図 3 に示す溝部 3を形成することができる。 しかも、 この溝部 3は、 前述したように シャフト 5に順次、 長尺部材 1を卷付けて管路を形成するに伴ってその内面に螺 旋状に形成される。 By the way, as described above, the long member 1 (1-3 position or 1-3 position or 1-2 position) located below the long member 1 (1-1 position or 1-2 position) ! /, Is 1- 4th The groove 3 shown in Fig. 3 can be formed by slightly offsetting the lower part when the upper part is placed on the upper part. Moreover, as described above, the groove 3 is spirally formed on the inner surface thereof as the long member 1 is sequentially wound around the shaft 5 to form a conduit.
上記螺旋状の溝部 3は、 フレキシブルパイプの一端から他端まで連続して形成 される。 この溝部 3は、 従来において何らの機能も果しておらず単なる管内のデ ッドスペースとなつてレ、た。 しかし、 本願発明^ はこのデッドスペースを有効 活用できることに着目して本発明に至ったものである。 すなわち、 前述したよう に長尺部材 1の上部と下部の一部を重ねるようにシャフト 5に卷付けを行ってフ レキシプルパイプを形成する際に、 所定容積の溝部 3を形成する。 そして、 この 溝部 3内に将来、 リ一ド線として用いる線材を供給しながらフレキシブルパイプ 1を製造すればよい。 溝部 3は長尺部材 1がシャフト 5卷付けられることにより 順次形成されるので、 この溝部 3が形成されるスピードに応じてリ一ド線を供給 すればよい。 また、 後述するようにフレキシブルパイプの作製が完了した後にシ ャフト 5を引き抜いたときに管内にリ一ド線が管路内に落ち込むようにするため は、 溝部 3内にこの溝部の容積よりも小さく比較的腰の弱いリ一ド線を遊嵌状態 にして収納すればよい。 The spiral groove 3 is formed continuously from one end to the other end of the flexible pipe. Conventionally, the groove 3 did not perform any function, and was merely a dead space in the pipe. However, the present invention is based on the fact that the dead space can be effectively used, and has led to the present invention. That is, as described above, when the flexible pipe is formed by winding the shaft 5 so that the upper part and the lower part of the long member 1 overlap with each other, the groove 3 having a predetermined volume is formed. Then, the flexible pipe 1 may be manufactured while supplying a wire used as a lead wire in the groove 3 in the future. Since the grooves 3 are sequentially formed by winding the long member 1 on the shaft 5, the lead wire may be supplied according to the speed at which the grooves 3 are formed. Also, as will be described later, in order for the lead wire to fall into the pipe when the shaft 5 is pulled out after the fabrication of the flexible pipe is completed, the volume of the groove 3 must be smaller than the volume of the groove. A small, relatively stiff lead wire should be loosely fitted and stored.
図 4は、 上記溝部 3内にリード線 2 0を供給しながら完成したフレキシブルパ ィプ 1 0を示した図である。 図 4では、 フレキシブノレパイプ 1 0の内眘 |5が 、で きるようにハッチングを入れて断面を示している。 この図 4は、 まだ内部にシリ ンダ 5を配置した状態を示すが、 このシリンダ 5を取除くと溝部 3からリード線 2 0が管路内落ち込む。 よって、 フレキシブルパイプ 1の製造工程に僅かな改良 を加えるだけで、 リ一ド線を揷通したフレキシブノレパイプ 1を製造することがで きる。 FIG. 4 is a view showing the completed flexible pipe 10 while supplying the lead wire 20 into the groove 3. In FIG. 4, the inside | 5 of the flexible pipe 10 is hatched so as to form a cross section. FIG. 4 shows a state in which the cylinder 5 is still disposed inside. However, when the cylinder 5 is removed, the lead wire 20 drops from the groove 3 into the pipeline. Therefore, the flexible pipe 1 that passes through the lead wire can be manufactured with only a slight improvement in the manufacturing process of the flexible pipe 1.
また、 シリンダ 5を取除レ、てもリード線 2 0が溝部 3 0力ら管路内に容易に落 ちず、 敷設現場で作業員がその端部を引っ張ったときに落ち込むような設計とし てもよい。 この:^には、 溝部 3 0の内面に 寸き自重を保持できる の弾性 を備えたリード線を採用すればよレ、。 このように設計しておけば、 挿通させたリ 一ド線がフレキシブルパイプ内で移動したり、 内部から大きくはみ出したりする ことを抑制できる。 In addition, even if the cylinder 5 is removed, the design is such that the lead wire 20 does not easily fall into the pipeline due to the groove 30 force, and falls when the worker pulls the end at the installation site. Is also good. For this: ^, it is advisable to use a resilient lead wire capable of holding its own weight on the inner surface of the groove 30. With this design, the inserted lead wire moves within the flexible pipe or protrudes greatly from the inside. Can be suppressed.
また、 前述した例では溝部 3にリード線を収納する例を説明したが、 敷設を行 う電線や光ファイバ自体をこの溝部 3内に収納してもよい。このような形態では、 リ一ド線を省略することができる。 In the above-described example, an example in which the lead wire is housed in the groove 3 has been described. However, the electric wire to be laid or the optical fiber itself may be housed in the groove 3. In such an embodiment, the lead line can be omitted.
以上本発明の好ましレ、実施例にっレ、て詳述したが、 本発明は係る特定の実施形 態に限定されるものではなく、 特許請求の範匪こ記載された本発明の要旨の範囲 内において、 種々の変形 '変更が可能である。 Although the preferred embodiments and examples of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and the gist of the present invention is described in the claims. Various modifications and changes are possible within the range of.
以上詳述したところから明らかなように、 本発明によると、 製造工程で形成さ れる溝部を有効に活用して、 従来の製造工程に簡易な変更を加えるだけで、 線材 を揷通したフレキシブルパイプを低コストで製造できるようになる。 As is apparent from the details described above, according to the present invention, the flexible pipe which penetrates the wire can be effectively utilized by simply utilizing the grooves formed in the manufacturing process and making simple changes to the conventional manufacturing process. Can be manufactured at low cost.
