本考案は、例えば電力ケーブルや通信ケーブル等の地中埋設ケーブルを保護す る硬質樹脂管及び橋梁添架ケーブル保護管の継手構造に関する。 The present invention relates to a joint structure of a hard resin pipe and a bridge-suspended cable protection pipe for protecting underground cables such as power cables and communication cables.
【０００２】[0002]
従来、この種樹脂管の継手構造として、図３に示すものが知られている。 この従来構造は、継手管100 における軸方向中心位置の内周面にストッパーリ ング101 を装設すると共に、該継手管100 の一端側に一方の樹脂管102 の端部を 挿入，接着した状態で現場に搬入し、現場において継手管100 の他端側に他方の 樹脂管103 の端部を挿入，接着するようになっていた。 Conventionally, as a joint structure for this kind of resin pipe, one shown in FIG. 3 is known. In this conventional structure, a stopper ring 101 is mounted on the inner peripheral surface of the joint pipe 100 at the axial center position, and one end of the joint pipe 100 is inserted and bonded to one end of the resin pipe 102. At that time, it was brought into the field, and the end of the other resin pipe 103 was inserted into and bonded to the other end of the joint pipe 100 at the site.
【０００３】[0003]
上記従来の継手構造によれば、他方の樹脂管103 の固定が現場における接着に よるものなので作業が面倒になるばかりか、樹脂管103 側，継手管100 側の接着 面の埃・油等の除去を完全に行うことが困難で、接続が不完全になる虞れがあっ た。 According to the conventional joint structure described above, the other resin pipe 103 is fixed by adhesion at the site, which not only complicates the work, but also prevents dust and oil from adhering to the resin pipe 103 side and the joint pipe 100 side. The removal was difficult to complete and could result in incomplete connections.
【０００４】 現場での接続が接着によらない手段として、図４に示すものも知られている。 この継手構造は、継手管200 の両端口縁にパッキン201 を介設すると共に、該継 手管200 の両端外周に螺嵌するナット202 の内周に、前記パッキン201 とナット 202 とで挟持されてその内径を縮小する締付けリング203 を装設してなり、継手 管200 の一端側，他端側に挿入する管体204 の端部を、その締付けリング203 の 締付け力によって固定するようになっている。As a means for connection in the field that does not rely on adhesion, the one shown in FIG. 4 is also known. In this joint structure, a packing 201 is provided on both ends of the joint pipe 200, and the packing 201 and the nut 202 are sandwiched between the inner periphery of a nut 202 screwed to the outer periphery of both ends of the joint pipe 200. A tightening ring 203 that reduces the inner diameter of the joint pipe 200 is installed, and the ends of the pipe body 204 inserted into one end side and the other end side of the joint pipe 200 are fixed by the tightening force of the tightening ring 203. ing.
【０００５】 しかし乍ら図４に示す継手構造は対強度に優れた金属管用のものであり、締付 けリング203 の締付け力によって管体が損傷する虞れがあるため、樹脂管の接続 に用いることはできなかった。However, the joint structure shown in FIG. 4 is for a metal pipe having excellent strength, and the pipe body may be damaged by the tightening force of the tightening ring 203. It could not be used.
【０００６】 本考案はこのような従来事情に鑑みてなされたものであり、その目的とすると ころは、継手管に挿入する樹脂管端部の固定が接着によるものではなく、且つ樹 脂管本体が損傷する虞れのない、硬質樹脂管の継手構造を提供することである。The present invention has been made in view of such a conventional situation, and an object thereof is to fix a resin pipe end portion to be inserted into a joint pipe by not adhering, and a resin pipe body. It is an object of the present invention to provide a joint structure for a hard resin pipe, which does not have a risk of being damaged.
【０００７】[0007]
前述の目的を達成するために、本考案に係る硬質樹脂管の継手構造は、軸方向 ほぼ中心位置の内周面にストッパーリングを装設した継手管内に、該継手管両端 から樹脂管端部を遊挿して先端を前記ストッパーリングに当接せしめ、且つ夫々 の樹脂管端部には、一端をストッパーリングに当接し他端内周をテーパー面とし たテーパーリングと、所望の弾性材を用いて略円錐形状に成形され前記テーパー 面に合致して樹脂管端部をストッパーリング方向へ付勢するグリップリングと、 該グリップリングに当接する押し輪とを外嵌挿着し、さらに上記継手管の両端に は前記押し輪をグリップリング方向へ押圧するナット体を螺嵌装着してなること を特徴とする。 In order to achieve the above-mentioned object, the joint structure of the hard resin pipe according to the present invention has a structure in which a stopper ring is provided on the inner peripheral surface at a substantially axial center position, and the resin pipe end portion is provided from both ends of the joint pipe. Loosely insert the tip into contact with the stopper ring, and for each resin pipe end, use a taper ring with one end in contact with the stopper ring and the inner circumference of the other end with a tapered surface, and a desired elastic material. A substantially conical shape that conforms to the tapered surface and urges the end of the resin pipe toward the stopper ring, and a push ring that abuts the grip ring are externally fitted and attached, and the joint pipe A nut body for pressing the push wheel in the grip ring direction is screwed and attached to both ends of the.
【０００８】[0008]
以上の構成によれば、ナット体を締付け操作してグリップリングをテーパーリ ングのテーパー面に圧接させることにより、グリップリングが弾性変形して楔作 用を発揮するをもって樹脂管端部をストッパーリング方向へ強固に付勢し、これ により継手管に挿入した樹脂管端部の抜けを防止する。よって、接着手段を用い ることなく継手管に挿入する樹脂管端部の固定を行い得ると共に、樹脂管端部を 径方向へ圧縮させる力が殆ど働かないので樹脂管本体が損傷する虞れもない。 According to the above configuration, by tightening the nut body and pressing the grip ring against the tapered surface of the tapered ring, the grip ring elastically deforms and exerts a wedge operation, and the end of the resin pipe is directed in the stopper ring direction. It is strongly urged to prevent the end of the resin pipe inserted into the joint pipe from coming off. Therefore, the resin pipe end portion to be inserted into the joint pipe can be fixed without using an adhesive means, and the resin pipe body may be damaged because the force for radially compressing the resin pipe end portion hardly acts. Absent.

It is formed in a possible ring shape, and a tapered surface 4a that tapers toward the other end is formed on the inner circumference of one end. The taper ring 4 is inserted into the joint pipe 1 by abutting the end 4b on the side where the taper surface 4a is not provided with the stopper ring 3. Actually, as shown in the drawing, ring-shaped packings 7, 7 are interposed between the respective taper rings 4 and the stopper rings 3.

Insert the tube end P10 of the resin tube P1 loaded with 8 into the tube end P10 in front of the push ring 8 and fit the taper ring 4 and the grip ring 5 onto the tube end P10. When the nut body 6 is tightened after the contact, the push ring 8 pushes the grip ring 5 toward the stopper ring 3. Due to the pressing force, the grip ring 3 presses against the tapered surface 4a and elastically deforms to exert a wedge action, thereby strongly urging the resin pipe end portion P10 toward the stopper ring 3 direction. Be sure to prevent it from coming off. Further, at this time, since the force for compressing the resin pipe end portion P10 in the radial direction hardly acts, there is no possibility of damaging the resin pipe P1.

Insert and fix in the following procedure to connect both resin pipes P1 and P2 to each other.
【００２０】 尚、本実施例においては、継手管１に挿入する管端部P10 ，P20 の固定及びそ の損傷防止をより効果的に行うために、継手管１，螺子リング２，ストッパーリ ング３，テーパーリング４，グリップリング５，ナット体６，押し輪８等の材質 を前述のものとしたが、それら各構成部材を前記以外の材料からなるものとして も、初期の目的を達成することは可能である。In this embodiment, in order to more effectively fix the pipe ends P10 and P20 to be inserted into the joint pipe 1 and prevent the damage thereof, the joint pipe 1, the screw ring 2, and the stopper ring. 3, the material of the taper ring 4, the grip ring 5, the nut body 6, the push ring 8 and the like has been described above, but the initial purpose can be achieved even if each of these constituent members is made of a material other than the above.

本考案に係る硬質樹脂管の継手構造は以上説明したように構成したので、ナッ ト体の操作によるグリップリングの弾性変形によって楔作用が発揮され、継手管 に挿入した樹脂管端部を挿入方向へ付勢してその抜けを防止し得る。 Since the joint structure of the hard resin pipe according to the present invention is configured as described above, the elastic deformation of the grip ring by the operation of the nut body exerts a wedge action, and the end of the resin pipe inserted into the joint pipe is inserted in the insertion direction. It can be biased to prevent it from coming off.
【００２２】 従って、管端部を径方向へ圧縮させる力が殆ど働かないので樹脂管本体が損傷 する虞れがなく、且つ、接着手段を用いることなく樹脂管端部の固定を行い得る ので、他方の樹脂管の固定が現場での作業になる配管作業を簡単且つ確実に行う ことができる、実用性・信頼性に優れた硬質樹脂管用継手構造を提供できた。Therefore, since the force for compressing the pipe end portion in the radial direction hardly acts, there is no risk of damaging the resin pipe body, and the resin pipe end portion can be fixed without using an adhesive means. We were able to provide a joint structure for hard resin pipes, which has excellent practicability and reliability, and can perform the piping work that fixes the other resin pipe, which is an on-site work, easily and reliably.
