Description

【0001】
【発明の属する技術分野】
本発明は伸縮性管継手機構に係り、接続すべき両管体をスライダブルに連結するようにした機構に関して上記のようにスライダブルな各管体の抜け出しを有効に防止し、しかも地下埋設管路の如きにおいて継手部シール材の摺動面に土砂等の侵入し損傷を来すことを有効に防止した機構を提供しようとするものである。
【0002】
【従来の技術】
配管部体を接続する管継手において連結された管体を伸縮自在とすることは連結された管体がそれなりに長尺部材であるような場合に温度変化による伸縮を可能ならしめ、また地盤変動などに即応する上において不可欠的であり、このように伸縮を可能とすることにより管路部体および継手機構の双方における損傷を回避し、適切な接続状態を形成維持することができる。
【0003】
然してこのような連結配管部体の伸縮を可能とした従来方式の代表例は図11に示す如くであって、継手部31で接続された両管体30、30にラグ32をそれぞれ設け、これらのラグ32、32をタイボルト33で連結するもので、継手部31に設けられたパッキング34を介して連結された両管体30、30はスライダブルであり、四季の温度変化などにおける伸縮が適宜に許容され、管体30や継手部31における損傷を適切に回避することができる。
【0004】
【発明が解決しようとする課題】
上記した図11に示すような管体接続装置は接続された両管体30、30が伸縮可能であって各管体30および継手部31をそうした伸縮によっても損傷しないが、接続された両管体30、30における伸縮によって両管体30、30の何れか一方が継手部31から抜出す可能がある。即ち仮りに1回の伸縮によって抜出さないとしても経年などにより伸縮が繰返されることによってタイボルト33を介し何れかの方向に移動し、管体30、30の何れかが継手部31から抜出すこととなる。例えば左側の管体30が固定状態であると右側の管体30が引張られて抜け出し限界が達し、その後それ以上に引張られるとこの右側の管体30が抜け出すこととなる。
【0005】
また地下配管の如きにあっては管体30の周辺土砂が継手部31の周側に埋装されることとなり、斯様な状態で管体30、30が伸縮することにより管体30の周側土砂が継手部31に侵入し、この侵入した土砂によって継手部31におけるパッキングの作用を阻害し、更にはシール部材を損傷せしめ何れにしても有効なシール関係を確保し得ないこととなる。
【0006】
また上記したような図11の従来方式によるものにおいては、継手機構が大型となり、しかもタイボルト33によって両管体30、30間における捩れ角度が制限されることとなり、このように両管体30、30の間における捩れ変位角が制限されることにより機構的に不具合を来すことが多いなどの不利がある。
【0007】
【課題を解決するための手段】
本発明は上記したような従来のものにおける不利を解消することについて検討を重ね、分割式としたカバーを採用すると共に該分割式カバーと管体との間に係止関係を構成することによってそれらの課題を適切に解決することに成功したものであって、以下の如くである。

【0009】
(2) 係止部体がリング状板材に台形保持片を配設し、該リング状板材の外端部を抜け止め部に対する係止部分としたことを特徴とする前記(1)の伸縮性管継手機構。
【0010】
(3) 係止部体が複数のリング状板材間に方形保持片を配設固定したことを特徴とする前記(1)の伸縮性管継手機構。

【0014】
然して、この図1〜3に示したものにおいては前記係止部体3が円輪状とされたリング状板材13に台形の保持片14の複数個を放射方向に配設し、このように保持片14の配設されたリング状板材13の周側端部に上述したような抜け止め部5に対する係止部分としたもので、前記抜け止め部5はリング状板材13とは別個の部材を取付けたものが示されているが、場合によってはリング状板材13の端部を折曲したようなものでもよい。上記したような抜け止め部5はカバー部体4の端部内孔径を縮小して土砂などの進入を阻止し、またカバー部体4の端縁部を補強して土砂圧などに耐えしめる。
【0015】
図4〜6には本発明によるもう1つの構成関係が示されており、管端部10、10と継手部材1によるパッキング2を用いた連結シール関係は上記した図1〜3のものと同様であり、抜け止め部5を有するカバー部体4についても同様であるが、係止部体3としては図5に示すように2枚のリング状板材13、13の間に方形保持片15を配設したものであり、前記継手部材1は図1〜3のものは2部体に分割したものであるのに対し、この図4〜6のものにおいては4部体に分割されたもので何れも連結手段6で連結されるが、この図4〜6のものにおいては一般的に図1〜3のものより大型管体の接続に適した構成を示すものである。
【0016】
なお図7〜図9には本発明による更に別の構成関係が示されている。即ち管端部20、20a間にパッキング2を介装し該パッキング2を取付部材6で一方の大径管体20に取付けると共に他方の小径管体20aの外面に接合シールせしめ、前記一方の大径管端部20における端部外面に小型の係止部体7を取付けると共に上記した他方の小径管端部20aには前記した図4〜6に示したものと同様なリング状板材13と保持片15から成る構成を有する大型の係止部体3を取付けたもので、これらの係止部体7および3と係合する分割式カバー部体4がその両端部に抜け止め部5を対設したことは上記したような図1〜3および図4〜6のものと同様である。
【0017】
更に本発明による分割式カバー部材5と係止部材3または7を用いた伸縮性管継手機構は図10に示すような構成として実施することができる。即ち接続すべき管端部として前記した図1〜図9の構成とは異り、同径の管体端部12、12の場合において、それらの管体端部12、12間に継手部材11を股設し、該継手部材11に内装されたパッキング2、2は継手部材11の端部における係止部16および内側係合部17によって定位置に保持されているが、上記のような係止部16に対し適宜に補助係止部18を取付け、しかも前記管端部12、12には上述したような係止部体3をそれぞれ取付けて、抜け止め部5、5を対設した既述のような分割式カバー部材4を各別に配設するようにしたものである。
【0018】
上記したような本発明によるものは、接続すべき管端部相互を継手部材に内装されたパッキングを介しスライダブルに連結したものにおいて、前記管端部における継手部材取付部分より外側に夫々係止部体を取付けると共にそれら係止部体を収容する分割式カバー部体を設け、該カバー部体の端部に前記係止部体と係止する抜け止め部を形成したことによって接続された管端部相互間において適宜に伸縮を可能ならしめ、しかも伸縮による何れか一方の抜け出し量(スライド量)が大となり、抜け出し限界以上にスライドするならば分割式カバー部体を介して他方の管体における係止部体に係止し、該他方の管体を一方の管体方向に引張ることとなり、両管体接続部における管体抜け出しを的確に阻止する。
【0019】
係止部体がリング状板材に保持片を配設し、該リング状板材の外端部を抜け止め部に対する係止部分としたことによって分割式カバー部体に設けられた抜け止め部との係止とそれに伴う上記したような引張り作用を的確に実現せしめる。

BACKGROUND OF THE INVENTION
The present invention relates to a stretchable pipe joint mechanism, which effectively prevents the slideable pipes from coming out as described above with respect to a mechanism in which both pipes to be connected are slidably connected. It is an object of the present invention to provide a mechanism that effectively prevents soil and sand from entering and damaging the sliding surface of the joint seal material in a road.
[0002]
[Prior art]
Making the pipes connected at the pipe joints connecting the pipe parts stretchable makes it possible to expand and contract due to temperature changes when the connected pipe is a long member as it is, and also the ground fluctuation Thus, it is indispensable to quickly respond to the above, and by enabling expansion and contraction in this way, damage in both the pipe section body and the joint mechanism can be avoided and an appropriate connection state can be formed and maintained.
[0003]
However, a typical example of the conventional method that enables expansion and contraction of such a connecting pipe body is as shown in FIG. 11, and lugs 32 are provided on both pipe bodies 30 and 30 connected by the joint part 31, respectively. The lugs 32 and 32 are connected by tie bolts 33, and both the pipe bodies 30 and 30 connected through the packing 34 provided in the joint portion 31 are slidable, so that the expansion and contraction due to the temperature change in the four seasons is appropriate. Therefore, damage to the pipe body 30 and the joint part 31 can be appropriately avoided.
[0004]
[Problems to be solved by the invention]
The tube connecting device as shown in FIG. 11 described above is capable of expanding and contracting both connected tube bodies 30 and 30 and does not damage each tube body 30 and joint portion 31 by such expansion and contraction. One of the tubular bodies 30 and 30 may be pulled out from the joint portion 31 due to the expansion and contraction of the bodies 30 and 30. That is, even if it is not pulled out by one expansion and contraction, the expansion and contraction is repeated due to aging, etc., so that it moves in either direction through the tie bolt 33 and one of the tubular bodies 30 and 30 is extracted from the joint portion 31. It becomes. For example, when the left tube 30 is in a fixed state, the right tube 30 is pulled to reach the pull-out limit, and when pulled further thereafter, the right tube 30 is pulled out.
[0005]
Moreover, in the case of underground piping, the surrounding earth and sand of the pipe body 30 is embedded in the peripheral side of the joint part 31, and the pipe bodies 30 and 30 expand and contract in such a state, so that the circumference of the pipe body 30 is increased. The side earth and sand enters the joint portion 31 and the intruded earth and sand impedes the action of packing in the joint portion 31 and further damages the seal member, so that an effective sealing relationship cannot be ensured in any case.
[0006]
Further, in the conventional system shown in FIG. 11 as described above, the joint mechanism is large, and the tie bolt 33 limits the twist angle between the two tubular bodies 30, 30. There are disadvantages such as the fact that the torsional displacement angle between 30 is often limited to cause mechanical problems.
[0007]
[Means for Solving the Problems]
