本考案は、電気、通信ケーブル用保護配管の補修・回避工事において、ケーブ ルを切断することなく、既設ケーブル保護管のみを切断除去し、切断された該保 護管の後端部と先端部との間に本考案の管継手を連結する自在管継手連結体であ って、既設管の切断の長さを制限する必要がなく、かつ、浸水、腐食および引き 抜き阻止対策を充分に施した自在管継手に関する。該自在管継手は先に開発した 異なる構造の二種類のアダプタとこの二種類のアダプタとの間を連結する異なっ た構造の三種類の中間管継手とから構成されている。 The present invention is for repairing and avoiding protection pipes for electric and communication cables, cutting and removing only the existing cable protection pipe without cutting the cable, and the rear end and the tip of the cut protection pipe. It is a universal pipe joint connecting body for connecting the pipe joint of the present invention between the above and the present invention, and it is not necessary to limit the cutting length of the existing pipe, and sufficient countermeasures against water immersion, corrosion and extraction are taken. Regarding universal joints. The universal pipe joint is composed of two types of previously developed adapters of different structures and three types of intermediate pipe joints of different structures for connecting the two types of adapters.

通信ケーブル用保護配管の補修用割継手として、塗覆鋼管割継手がある。図１ ８に示すように、左右対称の半割り構造になっており、この継手内部にはゴム筒 体が使用され、半割り部材をボルトで締付固定されている。従来の管継手の長さ Ｌは一定であり、連結して使用する構造になっていないため、補修用対象の配管 の長さがＬ以上のときは補修が不可能である。 As a split joint for repairing protective pipes for communication cables, there is a coated steel pipe split joint. As shown in Fig. 18, it has a symmetrical half-split structure, a rubber cylinder is used inside the joint, and the half-split members are fixed by bolts. Since the conventional pipe joint has a fixed length L and is not structured to be used by connecting it, repair cannot be performed when the length of the pipe to be repaired is L or more.
【０００３】 またケーブル用保護配管を埋設する場合、地盤沈下や地震対策として、継手引 抜阻止力が必要であるが、ゴム筒体を介してのフランジボルト締めのみでは、配 管の軸方向の引き抜き阻止力としては充分ではない。さらに埋設管の場合は、水 密性として高い耐浸水性が要求されるが、半割り部材型管と配管の間にはゴム筒 体を配管し、ボルトで締め付け固定されているが、軸方向に対しては高いシ−ル 性は得られない。Further, when burying a protective pipe for a cable, a joint pull-out prevention force is required as a measure against ground subsidence or an earthquake, but only by tightening a flange bolt through a rubber tubular body, It is not enough as a pull-out prevention force. Furthermore, in the case of a buried pipe, a high water-tightness is required as a watertight property, but a rubber tube is piped between the half-divided member type pipe and the pipe, and it is fastened with bolts. No high sealing property can be obtained.

【００４５】 図１７は自在管継手に可撓性をもたせた管継手部分の断面図を示している。 本実施例は以上のように構成されており、以下その組立てについて説明する 。図２における前記オスアダプタにおいて、まず抜け止めリング（２２）と弾性 体リング（２３）とを前記オスアダプタ（５）の半割り部材の双方に装着する。 次にシ−ル部材（図１３の図ｃ）を２箇のゴム輪の部分の切断面（図示されてい ないが、図５の図ｃと同じ）にて分離し、継がれる配管体（１）を囲んだあと、 該シ−ル部材が該オスアダプタの第二の溝（図１２の２６）と軸方向の溝（図１ ２の１２）に係合するようにして半割り部材を合わせてフランジ面をボルト締め する。FIG. 17 shows a sectional view of a pipe joint portion in which a universal pipe joint has flexibility. The present embodiment is configured as described above, and its assembly will be described below. In the male adapter shown in FIG. 2, first, the retaining ring (22) and the elastic ring (23) are attached to both half members of the male adapter (5). Next, the seal member (Fig. 13c) is separated at the cut surfaces of two rubber rings (not shown, but the same as Fig. 5c), and the pipe body (1 ), And then align the half member so that the seal member engages the second groove (26 in FIG. 12) and the axial groove (12 in FIG. 12) of the male adapter. Bolt the flange surface.
【００４６】 次に、図２に記載した第二中間管継手において、図８に記載したシ−ル部材の ２箇のリングの部分を切断面にて分離し、継がれるオスアダプタ（５）を囲んだ あと、前記オスアダプタのシ−ル部材（図１３の図ｃ５０８）をオスとしてメス 側（図８の図ａ１７４）に係合して両方のシ−ル部材を一体化し、所定の溝に係 合することを確認しながら前記第二中間管継手の半割り部材を合わせてフランジ 部をボルト締めする。以下同様な手段で前記第一中間管継手、第二中間管継手お よびメスアダプタとの連結を行い連結体が構成される。Next, in the second intermediate pipe joint shown in FIG. 2, the two ring portions of the seal member shown in FIG. 8 are separated at the cut surface, and the spliced male adapter (5) is attached. After enclosing, the male adapter seal member (FIG. 13 c508) is used as a male to engage the female side (FIG. 8 a174) to integrate both seal members into a predetermined groove. While confirming that they are engaged, align the half-split members of the second intermediate pipe joint and bolt the flange. Thereafter, the first intermediate pipe joint, the second intermediate pipe joint, and the female adapter are connected by similar means to form a connected body.
【００４７】 本考案の特徴として、ケーブル保護用配管本体は主として鋼管であるが、他の 材料例えば鋳鉄、銅、銅合金、アルミ合金およびプラスティックなどであっても 本管継手は充分に対応できる。なお、この場合管継手をこれらと同等な材料とす ることが望ましい。またシ−ル部材は一般にゴムを使用するが、ゴムと同等の弾 性を有する材料、例えばプラスティックであれば、それも可能である。As a feature of the present invention, the main body of the pipe for protecting the cable is mainly a steel pipe, but the present pipe joint can sufficiently cope with other materials such as cast iron, copper, copper alloy, aluminum alloy and plastic. In this case, it is desirable that the pipe joint be made of a material equivalent to these. Although rubber is generally used for the seal member, a material having elasticity equivalent to that of rubber, for example, plastic can be used.

（１）先に開発したオスおよびメスアダプタの内面に設けた抜け止めリングお よび弾性体リングは一体となって、ケーブル保護配管の地盤沈下や地震対策とし ての管継手と配管体との間の引き抜き阻止力を備えている。 （２）請求項１、２の両管継手と先に開発したオス、メスアダプタおよび中間 管継手は、配管体との結合部も含む管継手同士の結合部において、シ−ル機構が 互いのシ−ル部材を円周上で重ね合わせてシ−ルされるため、このシ−ル機構は 非常に高い水密性を有する。 (1) The retaining ring and the elastic ring provided on the inner surfaces of the male and female adapters developed earlier are integrated to form a space between the pipe joint and the pipe body as a measure against ground subsidence of the cable protection pipe and earthquake. It has a pull-out prevention force. (2) In both the pipe joints of claims 1 and 2, and the male and female adapters and the intermediate pipe joints previously developed, in the joint portion of the pipe joints including the joint portion with the pipe body, the seal mechanisms are mutually connected. Since the seal members are sealed by being superposed on the circumference, this seal mechanism has a very high watertightness.
【００４９】 （３）請求項１、２の両管継手と先に開発したオス、メスアダプタおよび中間 管継手は何れも構造が異なっているが、互いに連結することが可能である、とく に請求項１、２および先に開発された中間管継手をそれぞれ複数個使用すること により、補修配管の長さに任意性をもたせ、結合が可能である。また”可撓角” の効果により、連結された一連の継手部に湾曲をもたせることができるため、工 事が容易であり、かつ、工事現場の地形、例えば湾曲した場所に左右されること なく目的を達成することができる。(3) Both the pipe joints of claims 1 and 2 and the previously developed male and female adapters and intermediate pipe joints have different structures, but they can be connected to each other. By using a plurality of intermediate pipe joints developed in paragraphs 1 and 2, and a plurality respectively developed previously, the length of the repair pipe can be made arbitrary and can be connected. Also, due to the effect of the "flexibility angle", a series of joints that are connected can be curved, which facilitates the work and does not depend on the topography of the construction site, for example, the curved place. The purpose can be achieved.
