【発明の詳細な説明】
この発明は、例えばパイプとパイプとの接続に
使用する可撓継手に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible joint used, for example, to connect pipes.
従来、上記の可撓継手には、いわゆるベローズ
の両端にそれぞれフランジのような結合部をそれ
ぞれ設けたベローズ形管継手がある。しかし、こ
のようなベローズ形管継手では、その長さ方向に
大きな張力が加わつた場合やその周方向から大き
な圧力が加わつた場合には、ベローズが疲労し、
きれつが発生したりすることという問題があつ
た。 Conventionally, the above-mentioned flexible joints include so-called bellows-type pipe joints in which connecting portions such as flanges are provided at both ends of the bellows. However, in such bellows-type pipe joints, if large tension is applied in the length direction or large pressure is applied from the circumferential direction, the bellows will fatigue.
There was a problem with cracks occurring.
この発明は、上記の問題を解決した可撓継手を
提供することを目的とする。 An object of the present invention is to provide a flexible joint that solves the above problems.
そのため、この発明は、管状のゴム様弾性体
と、この弾性体の両端部にそれぞれ設けた金属製
結合部と、弾性体にその長さ方向に沿つて弛緩状
態で埋設されており両端が上記結合部に結合され
た複数条の抗張体と、弾性体内にその周縁部に沿
つて埋設した環状体とから構成されている。 Therefore, the present invention includes a tubular rubber-like elastic body, a metal joint provided at each end of the elastic body, and a metal joint part that is embedded in the elastic body in a relaxed state along its length, and both ends are It is composed of a plurality of tensile members connected to a joint, and an annular member embedded along the periphery of the elastic member.
このように構成した可撓継手では、弾性体によ
つて可撓性が得られる。しかも弾性体の長さ方向
に沿って弛緩状態の抗張体を埋設しているので、
その長さ方向に沿つて大きな張力が加えられて
も、弛緩状態の抗張体が伸びて緊張状態となるの
で、亀裂を生じることがない。また、弾性体の長
さ方向に垂直に曲げ力が加えられても、弛緩状態

内にその周縁部に沿つて環状体を埋設しているの
で、その全周方向から大きな圧力が加わつてもき
裂が生じることはない。 In the flexible joint configured in this way, flexibility is obtained by the elastic body. Moreover, since the tensile body in a relaxed state is embedded along the length of the elastic body,
Even if a large tension is applied along its length, the tensile member in a relaxed state stretches and becomes taut, so that no cracks occur. Further, even if a bending force is applied perpendicularly to the length direction of the elastic body, the tensile body in a relaxed state stretches in the direction of the bending force and becomes tensed, so that no cracks occur. Furthermore, since the annular body is embedded within the elastic body along its peripheral edge, no cracks will occur even if a large pressure is applied from the entire circumference direction.

4,4には仮想線で示すパイプが結合される。 Hereinafter, the present invention will be explained in detail based on one embodiment shown in the drawings. In FIG. 1, reference numeral 2 denotes a rubber-like elastic body, which is formed into a cylindrical body with a circular vertical cross section. Flanges 4, 4 are connected to both ends of this rubber-like elastic body 2, respectively. A pipe shown in phantom lines is connected to these flanges 4,4.

が互いに弛緩状態となるように行われている。 At the ends of the flanges 4, 4 inside the rubber-like elastic body 2, sleeves 6, 6 for attaching a chain are formed. The sleeves 6, 6 include a tensile member embedded in the rubber-like elastic member 2 along its length.
For example, four chains 8 are connected at 90° intervals. These chains 8 are buried in each chain ring 8a.
This is done so that the two are in a relaxed state.

Of course, this annular body 10 is also embedded within the rubber-like elastic body 2. The annular body 10 and the chain 8 are connected to each other by connecting the chain ring 8a to a fitting 12 provided on the outside of the annular body 10 and integrally therewith. Therefore, each annular body 10
is located inside each chain 8.

イプとの接続等にも使用できる。 Such a flexible joint is used, for example, as a joint for a cold water intake pipe of an ocean temperature difference power generation plant. The cold water intake pipe has a length of 500 to 700 m, and is suspended vertically from the sea surface to the seabed to draw cold water. Therefore, the strength against bending of the pipe becomes an important issue, but if these flexible joints are inserted at intervals of 50 to 100 m, even if a bending force is generated, for example from the upper side to the lower side in Figure 1, each chain 8 extend downward, become under tension, and receive the bending force. Further, the tension in the length direction due to the weight of the tube is received by each chain 8 in a relaxed state extending in its length direction and becoming in a tensioned state. Furthermore, deformation due to pressure from all around the circumference can be prevented by the annular body 10. In addition, this flexible joint can be used to connect pipes in pipelines laid on the ground surface or buried underground, or to connect pipes at the end of pipelines to cargo handling pipes to ships, etc. It can also be used for

Furthermore, as shown in FIG. 3, the chain 8 and the annular body 10 may be connected directly or via a shackle or the like. Further, although four threads of the chain 8 are provided, the number of threads can be increased or decreased. Further, although a circular annular body 10 is used, a rectangular one may also be used. Also,
The number of annular bodies 10 may also be increased or decreased arbitrarily. Although a plurality of separate members are embedded in the annular body 10, for example, only one spiral member may be embedded along the outer periphery of the rubber elastic body. moreover,
Although the chain 8 and the annular body 10 are connected, they do not necessarily need to be connected.
