Description

本発明は、管継手及びこれを用いた配管システムに関するものである。   The present invention relates to a pipe joint and a piping system using the same.

従来から雄継手部材と、雌継手部材と、抜け止め具とで構成した管継手が特許文献１により知られている。   Conventionally, a pipe joint composed of a male joint member, a female joint member, and a stopper is known from Patent Document 1.

上記特許文献１に示された従来例は、図１５に示されるように、雄継手部材５０に、鍔部５１と、鍔部５１から突設した鍔部５１よりも小径で且つ外周にＯリング５２を有する雄筒部５３と、鍔部５１の上記雄筒部５３と反対側に係合部５４とを設け、雌継手部材５６に雌筒部５７を設けると共に雌筒部５７の先端に鍔部５７ａを設けてある。また、抜け止め具５８は、基部６１と、基部６１から一体に分岐する一対の脚部５９と、これら一対の脚部５９と一体に設けられた互いに対向する円弧部６０とで本体部を構成し、円弧部６０の先端間に開口部６２を設け、円弧部６０の内側に係合突起６３を設け、更に、一対の円弧部６０の一部には軸方向に突出する一対の脚部６４を突設し、一対の脚部６４の先端に爪６５が形成してある。   As shown in FIG. 15, the conventional example shown in Patent Document 1 has a male joint member 50 having a flange 51 and a smaller diameter than the flange 51 protruding from the flange 51 and an O-ring on the outer periphery. 52, an engagement portion 54 provided on the opposite side of the collar portion 51 to the male cylinder portion 53, a female cylinder portion 57 provided on the female joint member 56, and a flange at the tip of the female cylinder portion 57. A portion 57a is provided. The retainer 58 includes a base portion 61, a pair of leg portions 59 branched integrally from the base portion 61, and arc portions 60 that are provided integrally with the pair of leg portions 59 and that face each other. In addition, an opening 62 is provided between the tips of the arc portion 60, an engagement protrusion 63 is provided inside the arc portion 60, and a pair of leg portions 64 projecting in the axial direction is part of the pair of arc portions 60. The claw 65 is formed at the tip of the pair of leg portions 64.

そして、本体部の一対の円弧部６０を鍔部５１に弾性的に被嵌して係合突起６３を係合部５４に係合し、更に、雌筒部５７を外周にＯリング５２を有する雄筒部５３に被嵌し、爪６５を雌筒部５７の先端に設けた鍔部５１の裏側に係止することで、雄継手部材５０と雌継手部材５６を嵌め込み接続すると共に、抜け止め具５８により雄筒部５３と雌筒部５７とが軸方向に抜けないようになっている。   Then, the pair of arc portions 60 of the main body portion are elastically fitted to the flange portion 51 to engage the engagement protrusion 63 with the engagement portion 54, and the female tube portion 57 has an O-ring 52 on the outer periphery. The male joint member 50 and the female joint member 56 are fitted and connected by fitting the male cylinder portion 53 and the claw 65 is locked to the back side of the flange portion 51 provided at the tip of the female cylinder portion 57, and the retaining portion is secured. The tool 58 prevents the male cylinder part 53 and the female cylinder part 57 from coming off in the axial direction.

しかしながら、上記の従来例にあっては、雌筒部５７と雄筒部５３とを嵌め込み接続するには、雄筒部５３の先端に雌筒部５７の先端を軸方向に位置合わせして雌筒部５７、雄筒部５３をそれぞれ軸方向に移動して嵌め込み作業を行う嵌め込み作業を行い始める際に、同時に一対の巾の狭い脚部６４の先端に設けた爪６５を押し広げるように雌筒部５７、雄筒部５３をそれぞれ軸方向に移動して雌筒部５７と雄筒部５３とを嵌め込む作業を行わなければならない。   However, in the above-described conventional example, in order to fit and connect the female tube portion 57 and the male tube portion 53, the tip of the female tube portion 57 is aligned with the tip of the male tube portion 53 in the axial direction. When starting the fitting operation in which the cylindrical portion 57 and the male cylindrical portion 53 are moved in the axial direction and the fitting operation is started, the female claws 65 provided at the tips of the pair of narrow legs 64 are simultaneously pushed and spread. The cylinder part 57 and the male cylinder part 53 must be moved in the axial direction to engage the female cylinder part 57 and the male cylinder part 53, respectively.

つまり、雄筒部５３の先端に雌筒部５７の先端を軸方向に位置合わせして嵌め込み作業を開始する際、同時に一対の巾の狭い脚部６４の先端に設けた爪６５を押し広げる作業を行うため、未だ十分に嵌めこまれていない状態で弾性を有する一対の巾の狭い脚部６４を押し広げる際に鍔部５１にかかる弾性力により雌筒部５７が雄筒部５３に対して軸方向に傾きやすくてスムーズな嵌め込みがし難くいものであり、また、嵌め込み時に雄筒部５３の軸方向に対して雌筒部５７の軸方向が斜めに傾いた状態で無理に嵌め込まれるため、Ｏリング５２が損傷するおそれがあり、嵌め込み接続部分から液体漏れ（例えば水漏れ）が生じるおそれがある。   That is, when the fitting operation is started by aligning the tip of the female tube portion 57 with the tip of the male tube portion 53 in the axial direction, the operation of simultaneously pushing the claws 65 provided at the tips of the pair of narrow leg portions 64 is performed. Therefore, when the pair of narrow leg portions 64 having elasticity are pushed in a state where they are not yet fully fitted, the female tube portion 57 is made to move against the male tube portion 53 by the elastic force applied to the flange portion 51. Since it is easy to tilt in the axial direction and is difficult to smoothly fit, and because it is forcibly fitted in a state in which the axial direction of the female cylindrical portion 57 is inclined with respect to the axial direction of the male cylindrical portion 53 at the time of fitting, The O-ring 52 may be damaged, and liquid leakage (for example, water leakage) may occur from the fitting connection portion.

また、雄筒部５３の外周にＯリング５２が設けてあるが、一対の巾の狭い脚部６４はこのＯリング５２の周方向の大部分を覆って保護する機能などはなく、したがって、嵌め込み接続するまでの間、雄筒部５３の外周に設けたＯリング５２が外部に露出している状態となり、傷付いたり、異物が付着したりし易い。ところが、このようにＯリング５２が傷付いたり、異物が付着していると、外周にＯリング５２を設けた雄筒部５３と雌筒部５７とを嵌め込み接続しても、嵌め込み接続部分から流体漏れ（例えば水漏れ）が生じるおそれがある。   Further, although the O-ring 52 is provided on the outer periphery of the male cylindrical portion 53, the pair of narrow leg portions 64 does not have a function of covering and protecting most of the circumferential direction of the O-ring 52, and therefore is fitted. Until the connection, the O-ring 52 provided on the outer periphery of the male tube portion 53 is exposed to the outside, and is easily damaged or foreign matter adheres. However, if the O-ring 52 is damaged or foreign matter adheres in this way, even if the male tube portion 53 and the female tube portion 57 provided with the O-ring 52 are fitted and connected, the fitting connection portion There is a risk of fluid leakage (eg water leakage).

また、従来にあっては、嵌め込み接続部分を外側からカバーして保護してないので、Ｏリング５２を介して雄筒部５３と雌筒部５７を嵌め込み接続した後において、雄継手部材５０又は雌継手部材５６の一方に外力が作用した場合、Ｏリング５２の周方向の一部を局部的に強く押圧してがたつきが生じたりし、この場合も流体漏れ（例えば水漏れ）が生じるおそれがある。   Further, in the prior art, since the fitting connection portion is not covered and protected from the outside, the male joint member 50 or the male cylinder member 57 or the female cylinder portion 57 is fitted and connected via the O-ring 52. When an external force is applied to one of the female joint members 56, a part of the O-ring 52 in the circumferential direction is strongly pressed locally to cause rattling, and also in this case, fluid leakage (for example, water leakage) occurs. There is a fear.

また、上記従来例にあっては、基部６１と、基部６１から一体に分岐する一対の脚部５９と、これら一対の脚部５９と一体に設けられた互いに対向する円弧部６０とで本体部を構成してあるので、基部６１と一対の脚部５９が一対の円弧部６０から周方向に突出した形状となり、このため、雄継手部材５０と雌継手部材５６とを接続した状態で、接続部分の周方向に基部６１と一対の脚部５９が大きく突出することになる。したがって、基部６１と一対の脚部５９が邪魔になって、抜け止め具５８で抜け止めした雄継手部材５０と雌継手部材５６との接続部分を狭い溝などに納めることができない。
特開２００２−３９４７２号公報 Further, in the above conventional example, the main body portion includes the base portion 61, the pair of leg portions 59 that branch integrally from the base portion 61, and the arc portions 60 that are provided integrally with the pair of leg portions 59 and face each other. Therefore, the base 61 and the pair of leg portions 59 project from the pair of arc portions 60 in the circumferential direction. Therefore, the male joint member 50 and the female joint member 56 are connected in a connected state. The base portion 61 and the pair of leg portions 59 project greatly in the circumferential direction of the portion. Accordingly, the base 61 and the pair of leg portions 59 are in the way, and the connecting portion between the male joint member 50 and the female joint member 56 that are prevented from being detached by the retaining member 58 cannot be stored in a narrow groove or the like.

本発明は上記の従来の問題点に鑑みて発明したものであって、簡単な構成で雄筒部の外周に設けたＯリングを保護してＯリングが傷付いたり、異物が付着したりするのを防止してＯリングの損傷による流体漏れを確実に防止でき、また、簡単な嵌め込み作業で軸方向の抜け止めと共に嵌め込み接続部分のがたつきを防止でき、また、狭い場所であっても嵌め込み接続部分を納めることができる管継手及びこれを用いた配管システムを提供することを課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and protects the O-ring provided on the outer periphery of the male tube portion with a simple configuration, so that the O-ring is damaged or foreign matter adheres. It is possible to prevent the fluid leakage due to the damage of the O-ring, and to prevent the fitting connection part from rattling with a simple fitting operation together with the axial stopper. It is an object of the present invention to provide a pipe joint capable of accommodating a fitting connection portion and a piping system using the pipe joint.

上記課題を解決するために本発明に係る管継手は、管継手１を雄継手部材２と雌継手部材３と抜け止め兼カバー部材４とで構成し、雄継手部材２に、第１被係止部５を設けた大径筒部６と、大径筒部６の軸方向の端部から一体に突設した大径筒部６よりも小径で且つ外周にＯリング７を有する雄筒部８とを設け、雌継手部材３に第２被係止部９を設けた雌筒部１０を設け、抜け止め兼カバー部材４の主体を構成する一側部が側部開口１１ａとなった割り筒部１１の軸方向の一端部側に第１係止部１２を設けると共に他端部に第２係止部１３を設け、割り筒部１１の一端部側を雄継手部材２の大径筒部６に被嵌して第１係止部１２を第１被係止部５に係止した状態で、割り筒部１１の軸方向の略中間部分で外周にＯリング７を設けた雄筒部８を隙間１４を介して覆い且つ割り筒部１１の軸方向の他端部を雄筒部８の先端よりも軸方向に突出させ、雌筒部１０と雄筒部８とを嵌め込むと共に第２係止部１３を第２被係止部９に係止して割り筒部１１で雄筒部８と雌筒部１０との嵌め込み接続部分を覆って成ることを特徴とするものである。   In order to solve the above-described problems, a pipe joint according to the present invention includes a male joint member 2, a female joint member 3, and a retaining / cover member 4, and the male joint member 2 includes a first engaged member. A large-diameter cylindrical portion 6 provided with a stop portion 5 and a male cylindrical portion having an O-ring 7 on the outer periphery that is smaller in diameter than the large-diameter cylindrical portion 6 integrally projecting from the axial end of the large-diameter cylindrical portion 6 8, a female cylinder part 10 provided with a second locked part 9 is provided on the female joint member 3, and one side part constituting the main body of the retaining / cover member 4 is a side part opening 11 a. A first locking portion 12 is provided on one end side in the axial direction of the tube portion 11 and a second locking portion 13 is provided on the other end portion, and one end portion side of the split tube portion 11 is connected to the large diameter tube of the male joint member 2. A male cylinder provided with an O-ring 7 on the outer periphery at a substantially intermediate portion in the axial direction of the split cylinder part 11 with the first locking part 12 locked to the first locked part 5 by being fitted to the part 6 Part 8 The other end portion in the axial direction of the split cylinder portion 11 is projected in the axial direction from the tip end of the male cylinder portion 8 so as to fit the female cylinder portion 10 and the male cylinder portion 8 and the second engagement. The stop portion 13 is locked to the second locked portion 9 and the split tube portion 11 covers the fitting and connecting portion between the male tube portion 8 and the female tube portion 10.

このような構成とすることで、雄筒部８と雌筒部１０とを嵌め込み接続する前までの間は、割り筒部１１の一端部側を雄継手部材２の大径筒部６に被嵌して第１係止部１２を第１被係止部５に係止しておくことで、割り筒部１１の軸方向の略中間部分で外周にＯリング７を設けた雄筒部８を隙間１４を介して覆うことができ、これにより嵌め込み接続するまでＯリング７が傷付いたり、異物が付着したりしないようにできて、Ｏリング７の損傷による流体漏れを確実に防止でき、また、割り筒部１１の軸方向の他端部を雄筒部８の先端よりも軸方向に突出させてあるので、嵌め込み接続に当って、まず、割り筒部１１の軸方向の他端部の突出部分に雌筒部１０を嵌め込んで雌筒部１０の軸方向を雄筒部８の軸方向に合わせて位置決めでき、この位置決めした状態で雌筒部１０、雄筒部８を軸方向に移動することで、割り筒部１１をガイドとして雌筒部１０がＯリング７を有する雄筒部８に簡単且つＯリング７を傷付けないようにスムーズに嵌め込まれ、嵌め込み接続作業が簡単且つ確実に行える。しかも、この嵌め込み接続状態で、第１係止部１２と第１被係止部５との係止、及び、第２係止部１３と第２被係止部９との係止により軸方向の抜け止めがなされると共に、割り筒部１１で雄筒部８と雌筒部１０との嵌め込み接続部分を覆うことで、割り筒部１１により嵌め込み接続部を外側から保護すると共に嵌め込み接続強度を向上させ、外力が作用した場合でも嵌め込み接続部ががたつかないようにできる。   By adopting such a configuration, one end of the split tube portion 11 is covered with the large diameter tube portion 6 of the male joint member 2 until the male tube portion 8 and the female tube portion 10 are fitted and connected. By fitting and locking the first locking portion 12 to the first locked portion 5, the male tube portion 8 provided with an O-ring 7 on the outer periphery at a substantially intermediate portion in the axial direction of the split tube portion 11. Can be covered through the gap 14, thereby preventing the O-ring 7 from being damaged or foreign matter from adhering until it is fitted and connected, and fluid leakage due to damage to the O-ring 7 can be reliably prevented, In addition, since the other end portion in the axial direction of the split cylinder portion 11 is protruded in the axial direction from the tip end of the male cylinder portion 8, first, the other end portion in the axial direction of the split cylinder portion 11 is first applied in the fitting connection. The female cylinder portion 10 is fitted into the protruding portion of the female cylinder portion 10 so that the axial direction of the female cylinder portion 10 is aligned with the axial direction of the male cylinder portion 8. By moving the female cylinder part 10 and the male cylinder part 8 in the axial direction in the positioned state, the female cylinder part 10 can be easily and easily attached to the male cylinder part 8 having the O-ring 7 by using the split cylinder part 11 as a guide. It is fitted smoothly so as not to damage, and the fitting connection work can be performed easily and reliably. Moreover, in this fitted connection state, the first locking portion 12 and the first locked portion 5 are locked, and the second locking portion 13 and the second locked portion 9 are locked in the axial direction. The split cylinder portion 11 covers the fitting connection portion between the male cylinder portion 8 and the female cylinder portion 10, thereby protecting the fitting connection portion from the outside and providing the fitting connection strength. It is possible to improve and prevent the fitting connection portion from rattling even when an external force is applied.

また、抜け止め兼カバー部材４が弾性を有する金属製であって、該抜け止め兼カバー部材４の主体を構成する割り筒部１１が断面略Ｃ字状をし、第１係止部１２を第１被係止部５に弾性係止すると共に第２係止部１３を第２被係止部９に弾性係止することが好ましい。   Further, the retainer / cover member 4 is made of a metal having elasticity, and the split cylinder portion 11 constituting the main body of the retainer / cover member 4 has a substantially C-shaped cross section, and the first locking portion 12 is It is preferable that the first locking portion 5 is elastically locked and the second locking portion 13 is elastically locked to the second locked portion 9.

このような構成とすることで、第１係止部１２の第１被係止部５への係止、第２係止部１３の第２被係止部９への係止が弾性を利用して簡単にできる。また、抜け止め兼カバー部材４が金属製であるため、嵌め込み接続部を覆った状態での外側からの保護強度が強く、また、金属製であるため、熱伝導性が良好で、例えば、床暖房パネルにおける配管を接続する管継手として用いた場合など、配管接続部における熱伝導性が向上して床暖房効果が向上する。また、抜け止め兼カバー部材４の主体を構成する割り筒部１１が断面略Ｃ字状をしているため、抜け止め兼カバー部材４で雄継手部材２と雌継手部材３との嵌め込み接続部分を覆っているといえども、抜け止め兼カバー部材４は嵌め込み接続部分の外径と殆ど変わらず、嵌め込み接続部分から抜け止め兼カバー部材４が外方に大きく突出することがなく、例えば、抜け止め兼カバー部材４で覆った嵌め込み接続部分を床暖房パネルなどの設備部材の凹溝などに収納するような場合であっても狭い凹溝であっても収納できる。   With this configuration, the first locking portion 12 is locked to the first locked portion 5 and the second locking portion 13 is locked to the second locked portion 9 using elasticity. And easy to do. Further, since the retainer and cover member 4 is made of metal, the protection strength from the outside in a state where the fitting connection portion is covered is strong, and since it is made of metal, the thermal conductivity is good, for example, the floor When used as a pipe joint for connecting pipes in a heating panel, the thermal conductivity in the pipe connection part is improved, and the floor heating effect is improved. Further, since the split cylinder portion 11 constituting the main body of the retaining / covering member 4 has a substantially C-shaped cross section, the retaining / covering member 4 fits and connects the male joint member 2 and the female joint member 3. Even though the cover and cover member 4 is almost the same as the outer diameter of the fitting connection portion, the stopper and cover member 4 does not protrude greatly from the fitting connection portion. The fitting connection portion covered with the stopper and cover member 4 can be accommodated in a concave groove of a facility member such as a floor heating panel or a narrow concave groove.

また、大径筒部６に環状の第１被係止部５を周設し、雌筒部１０に環状の第２被係止部９を周設し、第１係止部１２を第１被係止部５に回動自在に係止すると共に割り筒部１１の一端部側を雄継手部材２の大径筒部６に回動自在に被嵌して第１係止部１２を第１被係止部５に回動自在に係止し、雌筒部１０と雄筒部８とを嵌め込むと共に第２係止部１３を第２被係止部９に回動自在に係止することが好ましい。   An annular first locked portion 5 is provided around the large-diameter cylindrical portion 6, an annular second locked portion 9 is provided around the female cylindrical portion 10, and the first locking portion 12 is connected to the first locking portion 12. The first locking part 12 is fitted to the large-diameter cylindrical part 6 of the male joint member 2 so that the one end part side of the split cylindrical part 11 can be freely rotated and locked to the locked part 5. 1 is engaged with the engaged portion 5 in a freely rotatable manner, and the female tube portion 10 and the male tubular portion 8 are fitted therein, and the second engaging portion 13 is engaged with the second engaged portion 9 in a freely rotatable manner. It is preferable to do.

このような構成とすることで、嵌め込み接続前にＯリング７を設けた雄筒部８を床暖房パネルなどの設備部材の凹溝などに収納した状態で搬送したり、設備部材の施工などを行う際、Ｏリング７の外部に露出する部分に合わせて割り筒部１１を回動することで、割り筒部１１における側部開口１１ａが外部に露出することなく確実にＯリング７が外部に露出しないように覆ってＯリング７が傷付いたり、Ｏリング７に異物が付着するのを防止することができる。   By adopting such a configuration, the male tube portion 8 provided with the O-ring 7 before fitting connection is transported in a state where it is housed in a concave groove of an equipment member such as a floor heating panel, or the construction of the equipment member is performed. When performing, the split cylinder part 11 is rotated according to the part exposed to the outside of the O-ring 7, so that the O-ring 7 is reliably exposed to the outside without exposing the side opening 11 a in the split cylinder part 11. The O-ring 7 is covered so as not to be exposed, and the O-ring 7 can be prevented from being damaged or foreign matter adhering to the O-ring 7.

また、抜け止め兼カバー部材４の主体を構成する断面略Ｃ字状をした割り筒部１１の側部開口１１ａの両開口縁にそれぞれ受け片１５を突設して両受け片１５間の距離が受け片１５の突出基部間ほど狭く且つ受け片１５の先端間ほど広くなるように形成してあることが好ましい。   Further, receiving pieces 15 are provided at both opening edges of the side opening 11a of the split cylinder portion 11 having a substantially C-shaped cross section constituting the main body of the retaining and covering member 4, and the distance between the receiving pieces 15 is provided. However, it is preferable that the gap is formed so as to be narrower between the protruding bases of the receiving piece 15 and wider between the tips of the receiving piece 15.

このような構成とすることで、一対の受け片１５をガイドとして断面略Ｃ字状をした割り筒部１１を側部開口１１ａから雄継手部材２の大径筒部６に被嵌して第１係止部１２を第１被係止部５に簡単に係止することができる。   With such a configuration, the split cylinder portion 11 having a substantially C-shaped cross section with the pair of receiving pieces 15 as a guide is fitted into the large diameter cylinder portion 6 of the male joint member 2 from the side opening 11a. The one locking portion 12 can be easily locked to the first locked portion 5.

また、上記のような管継手１を用いて配管システムを構成することが好ましいものであり、これにより、管の接続が簡単な構成で流体漏れがない状態で確実にできる配管システムを提供できる。   In addition, it is preferable to configure the piping system using the pipe joint 1 as described above, and thereby, it is possible to provide a piping system that can reliably connect the pipes with a simple configuration and no fluid leakage.

本発明は、割り筒部の一端部側を雄継手部材の大径筒部に被嵌して第１係止部を第１被係止部に係止した状態で、割り筒部の軸方向の略中間部分で外周にＯリングを設けた雄筒部を隙間を介して覆うので、嵌め込み接続までの間、簡単な構成の抜け止め兼カバー部材の取付けによりＯリングを保護でき、Ｏリングの損傷による流体漏れを確実に防止できる。また、割り筒部の軸方向の他端部を雄筒部の先端よりも軸方向に突出させてあるので、上記突出部分に雌筒部を嵌め込んで軸方向の位置決め及び仮保持ができ、この軸方向位置決め仮保持状態で、割り筒部をガイドとして嵌め込み作業ができ、Ｏリングを傷付けないで嵌め込み接続作業を簡単且つ確実にできる。また、第１係止部と第１被係止部との係止及び第２係止部と第２被係止部との係止により軸方向の抜け止めができると共に、割り筒部により嵌め込み接続部分が覆われ、割り筒部により嵌め込み接続部を外側から保護して嵌め込み接続強度を向上させ、外力が作用した場合でも嵌め込み接続部ががたつかず、この点でも嵌め込み接続部からの流体漏れを確実に防止できる。   In the present invention, the axial direction of the split cylinder portion is such that one end portion side of the split cylinder portion is fitted to the large diameter cylindrical portion of the male joint member and the first locking portion is locked to the first locked portion. Since the male tube portion provided with an O-ring on the outer periphery is covered with a gap at a substantially middle portion of the O-ring, it is possible to protect the O-ring by attaching a cover member with a simple structure until fitting and connection. Fluid leakage due to damage can be reliably prevented. Further, since the other end portion in the axial direction of the split tube portion is protruded in the axial direction from the tip of the male tube portion, the female tube portion can be fitted into the protruding portion to perform axial positioning and temporary holding, In this axial positioning temporary holding state, the fitting operation can be performed using the split cylinder portion as a guide, and the fitting and connecting operation can be performed easily and reliably without damaging the O-ring. In addition, the locking between the first locking portion and the first locked portion and the locking between the second locking portion and the second locked portion can prevent the shaft from coming off, and it is fitted by the split cylinder portion.

The split cylinder part 11 used as the side part opening 11a is formed. The split cylinder portion 11 having a substantially C-shaped cross section is divided into three portions in the axial direction, one end portion in the axial direction becomes the first fitted portion 20, the middle portion in the axial direction becomes the intermediate fitted portion 21, and the axial direction The other end of the second portion is a second fitted portion 22. The first fitted portion 20, the intermediate fitted portion 21, and the second fitted portion 22 have the same inner diameter, and further have the same diameter as the outer diameter of the female tube portion 10 and the large-diameter tube portion 6 described above. ing.

割り筒部１１の軸方向の一端部の第１被嵌部２０に第１係止部１２を設けると共に他端部の第２被嵌部２２に第２係止部１３を設けてある。添付図面に示す実施形態においては、第１被嵌部２０の両側面部の一部をそれぞれ切起こして２個の切り起こし片１２ａを形成し、該切り起こし片１２ａを第１係止部１２としてある。ここで、上記切り起こし片１２ａは断面略Ｃ字状の割り筒部１１の中心軸に対して直角となるように割り筒部１１内に向けて突出するように切り起こしてある。   A first locking portion 12 is provided at the first fitted portion 20 at one end of the split cylinder portion 11 in the axial direction, and a second locking portion 13 is provided at the second fitted portion 22 at the other end. In the embodiment shown in the accompanying drawings, a part of each side surface portion of the first fitted portion 20 is cut and raised to form two cut and raised pieces 12a, and the cut and raised pieces 12a are used as the first locking portions 12. is there. Here, the cut and raised pieces 12a are cut and raised so as to protrude into the split cylinder portion 11 so as to be perpendicular to the central axis of the split cylinder portion 11 having a substantially C-shaped cross section.

第２被嵌部２２の両側面部の一部をそれぞれ切り起こして２個の切り起こし片１３ａを形成し、該切り起こし片１３ａを第２係止部１３としてある。切り起こし片１３ａは、断面略Ｃ字状の割り筒部１１の中心軸に対して傾斜するように割り筒部１１内に向けて切り起こしてあり、その傾斜の向きは、先端側ほど割り筒部１１の軸方向の他端から離れ且つ先端側ほど割り筒部１１の内面から離れるように傾斜している。   A part of each side surface portion of the second fitted portion 22 is cut and raised to form two cut and raised pieces 13 a, and the cut and raised pieces 13 a are used as the second locking portions 13. The cut-and-raised piece 13a is cut and raised toward the inside of the split cylinder part 11 so as to be inclined with respect to the central axis of the split cylinder part 11 having a substantially C-shaped cross section. The part 11 is inclined so as to be away from the other end in the axial direction and away from the inner surface of the split cylinder part 11 toward the distal end side.

断面略Ｃ字状の割り筒部１１の側部開口１１ａの両開口縁にそれぞれ受け片１５を略ハ字状となるように突設して両受け片１５間の距離が受け片１５の突出基部間ほど狭く且つ受け片１５の先端間ほど広くなっている。また、側部開口１１ａ間の開口巾は断面略Ｃ字状の割り筒部１１の径（直径）よりも小さくなっている。   The receiving pieces 15 are projected from both opening edges of the side opening 11 a of the split cylinder portion 11 having a substantially C-shaped cross section so as to be substantially C-shaped, and the distance between the receiving pieces 15 is the protrusion of the receiving piece 15. It is narrower between the bases and wider between the tips of the receiving pieces 15. Moreover, the opening width between the side part openings 11a is smaller than the diameter (diameter) of the split cylinder part 11 having a substantially C-shaped cross section.

図２に示すように、抜け止め兼カバー部材４はあらかじめ雄継手部材２に取付けられる。雄継手部材２への抜け止め兼カバー部材４の取付けに当たっては次のようにして行う。   As shown in FIG. 2, the retainer and cover member 4 is attached to the male joint member 2 in advance. The attachment of the retaining member / cover member 4 to the male joint member 2 is performed as follows.

すなわち、抜け止め兼カバー部材４の側部開口１１ａを弾性的に押し開いて割り筒部１１を側部開口１１ａから雄継手部材２に被嵌する。この場合、側部開口１１ａに一対の受け片１５をハ字状に設けてあるので、一対の受け片１５をガイドとして断面略Ｃ字状をした割り筒部１１の側部開口１１ａから雄継手部材２の大径筒部６に簡単に被嵌して取付けることができる。上記のようにして割り筒部１１の第１被嵌部２０を大径筒部６に回転可能に当接状態で被嵌すると共に第１係止部１２を構成する切り起こし片１２ａを第１被係止部５を構成する環状溝５ａに対して周方向に移動自在に係止し、また、中間被嵌部２１が外周にＯリング７を設けた雄筒部８を隙間１４を介して覆い、更に、第２被嵌部２２を雄筒部８の先端よりも軸方向に突出するように抜け止め兼カバー部材４が雄継手部材２に対して取付ける。このようにして雄継手部材２に取付けられた抜け止め兼カバー部材４は、雄継手部材２に対して回転自在であるが、第１係止部１２が第１被係止部５に係止することで軸方向には移動しないように取付けられる。   That is, the side opening 11a of the retainer and cover member 4 is elastically pushed open to fit the split cylinder portion 11 to the male joint member 2 from the side opening 11a. In this case, since the pair of receiving pieces 15 are provided in a C shape in the side opening 11a, the male joint is formed from the side opening 11a of the split cylinder portion 11 having a substantially C-shaped cross section using the pair of receiving pieces 15 as a guide. It can be easily fitted and attached to the large-diameter cylindrical portion 6 of the member 2. As described above, the first fitting portion 20 of the split cylinder portion 11 is rotatably fitted to the large-diameter cylinder portion 6 in a contact state, and the cut and raised pieces 12a constituting the first locking portion 12 are the first. The intermediate cylindrical portion 5 is locked to the annular groove 5a constituting the locked portion 5 so as to be movable in the circumferential direction, and the intermediate fitting portion 21 is provided with the O-ring 7 on the outer periphery via the gap 14. Further, the retainer and cover member 4 is attached to the male joint member 2 so that the second fitted portion 22 protrudes in the axial direction from the tip of the male tube portion 8. The retaining and covering member 4 attached to the male joint member 2 in this manner is rotatable with respect to the male joint member 2, but the first locking portion 12 is locked to the first locked portion 5. By doing so, it is attached so as not to move in the axial direction.

上記のように雄継手部材２に抜け止め兼カバー部材４を取付けることで、外周にＯリング７を設けた雄筒部８の周方向の大部分が断面略Ｃ字状をした割り筒部１１の中間被嵌部２１により覆われて保護されることになり、雄継手部材２に雌継手部材３を嵌め込み接続するまでの間、運搬や各種作業中にＯリング７が傷付いたり、異物が付着するのを防止することができるようになっている。このように、雄継手部材２と雌継手部材３との嵌め込み接続作業を行う前の段階で、雄筒部８の外周に設けたＯリング７に傷が付いたり、異物が付着したりしないように保護するので、後述のように雄筒部８と雌筒部１０とを嵌め込み接続した場合に、Ｏリング７による止水効果を低下させることなく、嵌め込み接続部分における流体漏れ（例えば水漏れ）を事前に防止することができることになる。   By attaching the retaining and covering member 4 to the male joint member 2 as described above, the split cylinder part 11 having a substantially C-shaped cross section in the circumferential direction of the male cylinder part 8 provided with the O-ring 7 on the outer periphery. Until the female joint member 3 is fitted and connected to the male joint member 2 and the O-ring 7 is damaged during transportation and various operations. It is possible to prevent adhesion. In this way, the O-ring 7 provided on the outer periphery of the male tube portion 8 is not scratched or foreign matter adheres before the fitting and connection work between the male joint member 2 and the female joint member 3 is performed. Therefore, when the male tube portion 8 and the female tube portion 10 are fitted and connected as will be described later, fluid leakage (for example, water leakage) at the fitting connection portion without reducing the water stop effect by the O-ring 7. Can be prevented in advance.

抜け止め兼カバー部材４を取付けてＯリング７を保護している雄継手部材２と雌継手部材３とを接続するには以下のようにして行う。   In order to connect the male joint member 2 and the female joint member 3 that are attached to the retaining and covering member 4 and protect the O-ring 7, the following is performed.

まず、図３に示すように、割り筒部１１の軸方向の他端部の雄筒部８の先端から突出している突出部分である第２被嵌部２２に雌継手部材３の雌筒部１０を嵌め込んで雌筒部１０の軸方向を雄筒部８の軸方向に合わせて位置決めすると同時に、軸方向の位置決めをした状態で第２被嵌部２２により雌筒部１０を仮保持する。この場合、第２被嵌部２２は側部開口１１ａの開口巾が直径よりも小さい略Ｃ字状をしているので、軸方向の位置決め状態が確実に保持される。また、第２被嵌部２２の両側に傾斜した弾性を有する切り起こし片１３ａが設けてあるので、切り起こし片１３ａが第２被嵌部２２に嵌め込んで軸方向の位置合わせをした雌筒部１０の両側面に弾接して位置合わせ状態をより確実に保持できるようになっている。ここで、切り起こし片１３ａの傾斜の向きが、先端側ほど割り筒部１１の軸方向の他端から離れ且つ先端側ほど割り筒部１１の内面から離れるように傾斜しているので、傾斜に沿って雌筒部１０を差し込むことができて、第２被嵌部２２への雌筒部１０の嵌め込みに当って切り起こし片１３ａが障害とならない。   First, as shown in FIG. 3, the female tube portion of the female joint member 3 is connected to the second fitted portion 22 that is a protruding portion protruding from the tip of the male tube portion 8 at the other end in the axial direction of the split tube portion 11. 10 is fitted and the axial direction of the female cylinder part 10 is aligned with the axial direction of the male cylinder part 8, and at the same time, the female cylinder part 10 is temporarily held by the second fitted part 22 in the axially positioned state. . In this case, since the second fitting portion 22 has a substantially C shape in which the opening width of the side opening 11a is smaller than the diameter, the axial positioning state is reliably maintained. In addition, since the cut and raised pieces 13a having elasticity inclined on both sides of the second fitted portion 22 are provided, the female cylinder in which the raised and raised pieces 13a are fitted into the second fitted portion 22 and aligned in the axial direction. The alignment state can be more reliably maintained by elastic contact with both side surfaces of the portion 10. Here, the inclination direction of the cut-and-raised piece 13a is inclined so that the tip side is farther from the other end in the axial direction of the split cylinder part 11 and the tip side is farther away from the inner surface of the split cylinder part 11. The female cylinder part 10 can be inserted along, and the cut-and-raised piece 13 a does not become an obstacle when the female cylinder part 10 is fitted into the second fitted part 22.

上記のようにして第２被嵌部２２に雌筒部１０を嵌め込んで軸方向の位置合わせをして仮保持した状態で、雄継手部材２、雌継手部材３を互いに近づく方向に移動して図４に示すように雌筒部１０と雄筒部８とを嵌め込み接続する。   In the state where the female tube portion 10 is fitted to the second fitted portion 22 as described above, and is axially aligned and temporarily held, the male joint member 2 and the female joint member 3 are moved toward each other. As shown in FIG. 4, the female tube portion 10 and the male tube portion 8 are fitted and connected.

この場合、雌筒部１０は上記のように第２被嵌部２２により軸方向の位置決め保持がなされて第２被嵌部２２にガイドされながら雄筒部８に嵌め込まれるのであるが、雌筒部１０は雄筒部８と中間被嵌部２１との間の隙間１４に嵌め込まれるので、中間被嵌部２１においてもガイドされ、雌筒部１０の中心軸と雄筒部８の中心軸とが一致するように軸方向の位置決めがなされたまま軸方向に誘導されながら嵌め込み作業ができるようになっており、この結果、Ｏリング７を有する雄筒部８に雌筒部１０を簡単且つＯリング７を傷付けないようにスムーズに嵌め込むことができる。このように嵌め込み作業中において雄筒部８に対して雌筒部１０は軸方向にガイドされながら嵌め込まれることになって、雌筒部１０が雄筒部８に対して斜めに被嵌されてＯリング７が噛み込まれて損傷するというような事態が生じることがなく、この点でも、Ｏリング７による止水効果を低下させることなく、嵌め込み接続部分における流体漏れ（例えば水漏れ）を事前に防止することができることになる。   In this case, the female cylinder portion 10 is positioned and held in the axial direction by the second fitted portion 22 as described above and is fitted into the male tubular portion 8 while being guided by the second fitted portion 22. Since the portion 10 is fitted in the gap 14 between the male tube portion 8 and the intermediate fit portion 21, it is also guided in the intermediate fit portion 21, and the center axis of the female tube portion 10 and the center axis of the male tube portion 8 are Can be fitted while being guided in the axial direction while being positioned in the axial direction so that they coincide with each other. As a result, the female cylindrical portion 10 can be easily attached to the male cylindrical portion 8 having the O-ring 7 and O. The ring 7 can be fitted smoothly so as not to be damaged. Thus, during the fitting operation, the female tube portion 10 is fitted to the male tube portion 8 while being guided in the axial direction, and the female tube portion 10 is obliquely fitted to the male tube portion 8. The situation that the O-ring 7 is bitten and damaged does not occur, and in this respect as well, fluid leakage (for example, water leakage) at the fitting connection portion is prevented in advance without reducing the water-stopping effect by the O-ring 7. Can be prevented.

Ｏリング７を外周に設けた雄筒部８と雌筒部１０を完全に嵌め込むと、ちょうど雌筒部１０の先端が大径筒部６の端面に当たり、且つ、この状態で第２係止部１３となる切り起こし片１３ａが第２被係止部９となる環状溝９ａに位置して弾性的に係止する。   When the male tube portion 8 and the female tube portion 10 provided with the O-ring 7 on the outer periphery are completely fitted, the tip of the female tube portion 10 just contacts the end surface of the large-diameter tube portion 6, and in this state, the second locking The cut-and-raised piece 13 a that becomes the portion 13 is positioned in the annular groove 9 a that becomes the second locked portion 9 and is elastically locked.

上記のようにして雄筒部８と雌筒部１０との嵌め込みというワンタッチの作業で雄継手部材２と雌継手部材３とを嵌め込み接続できる。   As described above, the male joint member 2 and the female joint member 3 can be fitted and connected by a one-touch operation of fitting the male cylinder portion 8 and the female cylinder portion 10.

雄継手部材２と雌継手部材３とが上記のようにして嵌め込み接続された状態で、第１係止部１２と第１被係止部５との係止、及び、第２係止部１３と第２被係止部９との係止により軸方向の抜け止めがなされることになり、嵌め込みというワンタッチの作業で接続できるようにしたにもかかわらず、簡単な構成で軸方向の抜け止めができることになる。また、割り筒部１１により雄筒部８と雌筒部１０との嵌め込み接続部分が覆われるので、割り筒部１１により嵌め込み接続部を外側から保護すると共に嵌め込み接続強度を向上させることができ、この結果、雄継手部材２又は雌継手部材３に外力が作用した場合でも嵌め込み接続部ががたつかないようにでき、この点でもＯリング７の周方向の一部に無理な力が集中して嵌め込み接続部分からの流体漏れ（例えば水漏れ）を防止することができる。   In a state where the male joint member 2 and the female joint member 3 are fitted and connected as described above, the first locking portion 12 and the first locked portion 5 are locked and the second locking portion 13 is engaged. And the second locked portion 9 are prevented from coming off in the axial direction, and can be connected by a one-touch operation of fitting, but the axial construction is prevented with a simple configuration. Will be able to. Moreover, since the fitting connection part of the male cylinder part 8 and the female cylinder part 10 is covered by the split cylinder part 11, the fitting connection part can be protected from the outside by the split cylinder part 11, and the fitting connection strength can be improved. As a result, even when an external force is applied to the male joint member 2 or the female joint member 3, the fitting connection portion can be prevented from rattling, and in this respect, too much force is concentrated on a part of the O-ring 7 in the circumferential direction. It is possible to prevent fluid leakage (for example, water leakage) from the fitting connection portion.

図８乃至図１３には本発明の管継手１を用いた配管システムの一例として、床暖房における配管システムの例が示してある。   8 to 13 show an example of a piping system in floor heating as an example of a piping system using the pipe joint 1 of the present invention.

図中２３は床パネルであって、床基材２３ａの表面に表面化粧材２３ｂを積層して床パネル２３が構成してある。床基材２３ａの下面側には下方に開口した配管溝１９が形成してあり、の配管溝１９は、図９に示すように、一端が引出し口２５に連通し他端が引込み口２６に連通した一筆書き形状をしている。本例では配管溝１９は床パネル２３の全体に行き渡るような蛇行状に形成してある。   In the figure, reference numeral 23 denotes a floor panel, which is constructed by laminating a surface decorative material 23b on the surface of a floor base material 23a. A pipe groove 19 opened downward is formed on the lower surface side of the floor base material 23a. As shown in FIG. 9, one end of the pipe groove 19 communicates with the drawer outlet 25 and the other end leads to the inlet 26. Has a single stroke shape. In this example, the piping groove 19 is formed in a meandering shape so as to reach the entire floor panel 23.

図８（ａ）に示すように、床パネル２３の幅方向Ａの一側面２９ａに引出し口２５が形成されると共に、引出し口２５近傍の配管溝１９部分が引出し溝部２４とされており、この引出し溝部２４は引出し口２５が開口する床パネル２３の一側面２９ａに対して鋭角（図１１（ａ）のθ）で傾斜している。一方、床パネル２３の幅方向Ａの他側面２９ｂには上記引出し口２５と相対する位置に引込み口２６が形成され、引込み口２６近傍の配管溝１９部分が引込み溝部２８とされており、この引込み溝部２８は引込み口２６が開口する床パネル２３の他側面２９ｂに対して鋭角（図１１（ｂ）のθ´（＝θ））で傾斜している。そして、一方の床パネル２３Ａの引出し口２５と他方の床パネル２３Ｂの引込み口２６とを互いに対向させた状態で、一方の床パネル２３Ａの引出し溝部２４と他方の床パネル２３Ｂの引込み溝部２８とが略直線状に連通するように構成されている。   As shown in FIG. 8A, a drawer port 25 is formed on one side surface 29a in the width direction A of the floor panel 23, and a pipe groove 19 portion in the vicinity of the drawer port 25 serves as a drawer groove portion 24. The drawer groove portion 24 is inclined at an acute angle (θ in FIG. 11A) with respect to one side surface 29a of the floor panel 23 where the drawer port 25 opens. On the other hand, on the other side surface 29b in the width direction A of the floor panel 23, a drawing port 26 is formed at a position opposite to the drawing port 25, and a pipe groove 19 portion in the vicinity of the drawing port 26 serves as a drawing groove portion 28. The lead-in groove portion 28 is inclined at an acute angle (θ ′ (= θ) in FIG. 11B) with respect to the other side surface 29b of the floor panel 23 where the lead-in port 26 opens. Then, in a state where the drawing port 25 of one floor panel 23A and the drawing port 26 of the other floor panel 23B are opposed to each other, the drawing groove portion 24 of one floor panel 23A and the drawing groove portion 28 of the other floor panel 23B Are configured to communicate in a substantially straight line.

さらに、上記引出し溝部２４には、可撓性の配管１７の余長配管１７ｃを吸収するための凹み部３０が形成されている。この凹み部３０は、図１１に示すように、くびれ部３１よりも奥部を引出し溝部２４の傾斜方向（図１１（ａ）のＸ方向）に対して略直交方向（本例では床パネル２３の一側面２９ａに近接する方向）に向かって凹んだアール形状の内面４０ａを有する第１の凹み部３０ａと、くびれ部３１よりも手前部を第１の凹み部３０ａの凹み方向と反対方向（本例では床パネル２３の一側面２９ａから遠ざかる方向）に向かって凹んだアール形状の内面４０ｂを有する第２の凹み部３０ｂとからなる。これら各凹み部３０ａ，３０ｂはそれぞれ引出し溝部２４と連通しており、搬送時及び配管接続後にそれぞれ可撓性の配管１７の余長配管１７ｃを吸収して配管１７を納まり良く収納する働きをする。   Further, the drawing groove portion 24 is formed with a recess portion 30 for absorbing the extra length piping 17c of the flexible piping 17. As shown in FIG. 11, the recessed portion 30 has a deeper portion than the constricted portion 31, and a substantially orthogonal direction (in this example, the floor panel 23) with respect to the inclination direction of the drawing groove portion 24 (X direction in FIG. 11A). A first recess 30a having a rounded inner surface 40a that is recessed toward the one side surface 29a) and a front side of the constricted portion 31 in a direction opposite to the recess direction of the first recess 30a ( In this example, it is composed of a second recessed portion 30b having a rounded inner surface 40b that is recessed toward the side surface 29a of the floor panel 23). Each of the recesses 30a and 30b communicates with the drawing groove 24, and functions to store the pipe 17 well by absorbing the extra length pipe 17c of the flexible pipe 17 at the time of conveyance and after connection of the pipe. .

さらに、図１０（ａ）、図１１（ａ）に示すように、上記引出し溝部２４からは、配管１７の一方の端部に接続した雄継手部材２を引出し口２５よりも内側に入り込んだ位置に仮収容するための仮収容溝３２が分岐形成されている。仮収容溝３２の一端はくびれ部３１を介して第１の凹み部３０ａに連通している。本例では第１の凹み部３０ａのアール形状の内面４０ａの延長線上に沿わせて仮収容溝３２が延設されており、床パネル２３の搬送時に、図１１（ａ）のＷで示すように、配管１７の一方の端部に接続した雄継手部材２を仮収容溝３２に収納した状態で配管１７が第１の凹み部３０ａに向かって折り曲げられてアール形状の内面４０ａに押し付けられた状態で保持されるものである。   Further, as shown in FIG. 10A and FIG. 11A, a position where the male joint member 2 connected to one end portion of the pipe 17 enters the inside of the drawing port 25 from the drawing groove portion 24. The temporary storage groove 32 for temporary storage is formed in a branched manner. One end of the temporary accommodation groove 32 communicates with the first recess 30 a via the constriction 31. In this example, the temporary accommodation groove 32 is extended along the extended line of the round-shaped inner surface 40a of the first recess 30a, and is indicated by W in FIG. The pipe 17 is bent toward the first recess 30a and pressed against the rounded inner surface 40a in a state where the male joint member 2 connected to one end of the pipe 17 is housed in the temporary housing groove 32.

The piping 17 is made of flexible pipes such as a synthetic resin having elasticity or a rubber hose. Note that the pipe main body housed in the pipe groove 19 excluding the drawing groove part 24 may be a hard pipe, and only the pipe end housed in or drawn from the drawing groove part 24 may be the flexible pipe 17. The pipe connection portion 16 of the male joint member 2 in the pipe joint 1 of the present invention is fitted into one end portion of the pipe 17 and fastened with a fastening band or the like, and the pipe connection portion of the female joint member 3 is attached to the other end portion. 18 is fitted and fastened with a fastening band or the like. Further, the male joint member 2 is provided with the retaining / cover member 4 as described above. In addition, 39 in FIG. 8 is a pipe pressing tool, which serves to attach the pipe 17 housed in the pipe groove 19 to the floor base material 23a by partially pressing it.

ここで、雄継手部材２を接続した方の可撓性を有する配管１７の一端部側は引出し口２５から引き出し可能とされ、雌継手部材３を接続した方の可撓性を有する配管１７の他端部側は引込み溝部２８内部に配置される。   Here, one end portion side of the flexible pipe 17 to which the male joint member 2 is connected can be pulled out from the outlet 25, and the flexible pipe 17 to which the female joint member 3 is connected is provided. The other end side is disposed inside the drawing groove 28.

床パネル２３の下面には配管溝１９及び引出し溝部２４を覆うようにアルミ箔からなる均熱板２３ｃが取着される。均熱板２３ｃは、配管１７から床パネル２３表面への熱伝導の均一化を図る働きをする。なお、床パネル２３の下面のうち、図８（ａ）、図１０（ａ）、図１１（ａ）に示すように、床パネル２３の引出し口２５付近から仮収容溝３２に至る下面領域Ｅ、及び図８（ａ）、図１０（ｂ）、図１１（ｂ）の引込み口２６から引込み溝部２８に至る下面領域Ｆは、それぞれ、均熱板２３ｃで覆われない領域となっている。   A soaking plate 23 c made of aluminum foil is attached to the lower surface of the floor panel 23 so as to cover the piping groove 19 and the drawing groove portion 24. The soaking plate 23c functions to make the heat conduction from the pipe 17 to the surface of the floor panel 23 uniform. Of the lower surface of the floor panel 23, as shown in FIGS. 8 (a), 10 (a), and 11 (a), a lower surface area E extending from the vicinity of the drawer opening 25 of the floor panel 23 to the temporary accommodation groove 32. 8A, FIG. 10B, and FIG. 11B, the lower surface area F from the inlet 26 to the inlet groove 28 is an area that is not covered with the heat equalizing plate 23c.

そして、配管接続を行うまでの間（保管時、搬送時、及び、現場における接続作業までの取扱い作業時）は、図１１（ａ）の破線Ｗで示すように、配管１７の一方の端部に接続した抜け止め兼カバー部材４を取付けた雄継手部材２を仮収容溝３２に仮収容することにより、配管１７が第１の凹み部３０ａの内面４０ａに押し付けられて保持されるようになる。このようにして、配管１７の余長配管１７ｃが第１の凹み部３０ａの内面４０ａに押し付けられて保持された状態となって配管１７の一方の先端に接続した雄継手部材２が外部に飛び出さないようになっている。この場合、雄継手部材２に取付けた抜け止め兼カバー部材４は断面略Ｃ字状の割り筒部１１の側部開口１１ａが仮収容溝３２の溝底側を向いて一対の受け片１５の先端が仮収容溝３２の溝底に当接するように仮収容溝３２内に収容するようになっている。   During the time until the pipe is connected (during storage, transportation, and handling work up to the connection work in the field), as shown by the broken line W in FIG. By temporarily housing the male joint member 2 attached with the retaining and cover member 4 connected to the inner wall 40a in the temporary housing groove 32, the pipe 17 is pressed against and held by the inner surface 40a of the first recess 30a. . In this way, the extra length pipe 17c of the pipe 17 is pressed against and held by the inner surface 40a of the first recess 30a, and the male joint member 2 connected to one end of the pipe 17 protrudes to the outside. It is supposed not to. In this case, the retaining and covering member 4 attached to the male joint member 2 has the side opening 11a of the split cylinder portion 11 having a substantially C-shaped cross section facing the groove bottom side of the temporary housing groove 32 and the pair of receiving pieces 15. The tip is accommodated in the temporary accommodation groove 32 such that the tip abuts against the groove bottom of the temporary accommodation groove 32.

これにより仮収容溝３２の下面開口からＯリング７を有する雄筒部８が露出しないように割り筒部１１により覆ってカバーすることができ、出荷から配管作業を行うまでの間、Ｏリング７部分に他の物が当って傷付いたり、あるいは、異物が付着するのを防止するようになっている。   Thus, the male cylinder part 8 having the O-ring 7 can be covered and covered with the split cylinder part 11 so that the male cylinder part 8 having the O-ring 7 is not exposed from the lower surface opening of the temporary accommodation groove 32. It is designed to prevent other parts from hitting the part and getting damaged or foreign matter adhering.

また、配管１７接続時には、図１１（ａ）の１点鎖線Ｘで示すように、配管１７を略直線状に伸ばして引出し溝部２４の溝壁面２４ｂ，２４ｃに沿わせて配管１７の一方の端部に接続した雄継手部材２を引出し口２５から引出して配管接続できる状態とするものであり、さらに、配管接続後には、図１１（ａ）の２点鎖線Ｙで示すように、配管１７が凹み部３０ａ，３０ｂに向かって略Ｓ字状に折り曲げられた状態となるように構成されている。   When the pipe 17 is connected, as shown by a one-dot chain line X in FIG. 11A, the pipe 17 is extended substantially linearly and along one of the ends of the pipe 17 along the groove wall surfaces 24b and 24c of the lead-out groove 24. The male joint member 2 connected to the portion is pulled out from the outlet 25 so that the pipe can be connected. After the pipe connection, as shown by a two-dot chain line Y in FIG. It is comprised so that it may be in the state bent by the substantially S shape toward the dent parts 30a and 30b.

次に現場において床パネル２３を敷設して幅方向Ａに隣合う床パネル２３の配管接続を行なうことについて説明する。   Next, laying the floor panel 23 at the site and performing piping connection of the floor panel 23 adjacent in the width direction A will be described.

まず、下地板３４から立ち上げた立ち上げケーブル（図示せず）の端部に抜け止め兼カバー部材４を取付けた雄継手部材２を接続し、この雄継手部材２を最初に敷設しようとする一方の床パネル２３Ａの配管１７の他端の雌継手部材３に前述と同様にして嵌め込み接続して嵌め込み接続部分を一方の床パネル２３Ａの引き込み溝部２８内に収納すると共に、配管１７の他端部に接続した抜け止め兼カバー部材４を取付けた雄継手部材２を仮収容溝３２から取り出して配管１７の余長部分と共に外に引出し口２５から引き出す。   First, the male joint member 2 to which the retainer and cover member 4 is attached is connected to the end of a rising cable (not shown) raised from the base plate 34, and this male joint member 2 is first laid. The female joint member 3 at the other end of the pipe 17 of one floor panel 23A is fitted and connected in the same manner as described above, and the fitting connection portion is accommodated in the drawing groove 28 of the one floor panel 23A and the other end of the pipe 17 is connected. The male joint member 2 to which the retaining and cover member 4 connected to the part is attached is taken out from the temporary housing groove 32 and pulled out from the drawing port 25 together with the extra length portion of the pipe 17.

この状態で、一方の床パネル２３Ａの下面の均熱板２３ｃで覆ってない床パネル２３Ａの引出し口２５付近から仮収容溝３２に至る下面領域Ｅ、及び引込み口２６から引込み溝部２８に至る下面領域Ｆを覆うように、それぞれアルミ箔のような均熱シート３５ａ、３５ｂを貼着する。   In this state, the lower surface area E extending from the vicinity of the drawer opening 25 of the floor panel 23A not covered by the heat equalizing plate 23c on the lower surface of one floor panel 23A to the temporary housing groove 32, and the lower surface extending from the inlet 26 to the drawing groove 28. Soaking sheets 35a and 35b, such as aluminum foil, are pasted so as to cover the region F.

その後、最初に敷設しようとする床パネル２３Ａの下面を下地板３４上に接着剤による接着、その他の手段で固着する。   Thereafter, the lower surface of the floor panel 23A to be laid first is fixed on the base plate 34 by bonding with an adhesive or other means.

次に、上記下地板３４上に敷設した一方の床パネル２３Ａの上に、他方の床パネル２３Ｂを上下逆にして重ね、他方の床パネル２３の引込み溝部２８内に配置している配管１７の他端部に接続した雌継手部材３を可撓性を有する配管１７部分を曲げるようにして起こすことで引き込み溝部２８から出し、該他方の床パネル２３の雌継手部材３と、上記一方の床パネル２３Ａの引出し口２５から引き出した抜け止め兼カバー部材４を取付けた雄継手部材２とを嵌め込み接続する。雌継手部材３と雄継手部材２との接続は、雌筒部１０とＯリング７を有する雄筒部８との嵌め込みにより接続するものであり、この雌筒部１０とＯリング７を有する雄筒部８との嵌め込み接続に当って、雄継手部材２に取付けている抜け止め兼カバー部材４が前述のように嵌め込みに際しての軸方向の位置決め、仮保持、嵌め込みの際のガイドをおこない、また、嵌め込み接続が完了すると、前述のように第１係止部１２と第１被係止部５との係止及び第２係止部１３と第２被係止部９との係止により軸方向の抜け止めがなされる割り筒部１１で雄筒部８と雌筒部１０との嵌め込み接続部分を覆うことで、嵌め込み接続強度を向上させ、外力が作用した場合でも嵌め込み接続部ががたつかないようになる。   Next, the other floor panel 23B is turned upside down on one floor panel 23A laid on the base plate 34, and the piping 17 disposed in the drawing groove 28 of the other floor panel 23 is placed. The female joint member 3 connected to the other end is raised from the pull-in groove 28 by raising the flexible pipe 17 so as to be bent, and the female joint member 3 of the other floor panel 23 and the one floor The male joint member 2 to which the retainer and cover member 4 pulled out from the drawer opening 25 of the panel 23A is attached is fitted and connected. The female joint member 3 and the male joint member 2 are connected by fitting the female cylinder part 10 and the male cylinder part 8 having the O-ring 7. In the fitting connection with the cylindrical portion 8, the retaining and covering member 4 attached to the male joint member 2 performs axial positioning, temporary holding, and guiding when fitting as described above, and When the fitting connection is completed, as described above, the first locking portion 12 and the first locked portion 5 are locked and the second locking portion 13 and the second locked portion 9 are locked. Covering the fitting connection portion between the male cylinder portion 8 and the female cylinder portion 10 with the split cylinder portion 11 that prevents the direction from coming off, improves the fitting connection strength, and the fitting connection portion is rattled even when an external force is applied. I'm not connected.

嵌め込み接続が終了すると、接続部分が抜け止め兼カバー部材４で覆われた雌継手部材３と雄継手部材２が他方の床パネル２３Ｂの引込み溝部２８内に配置される。この場合、抜け止め兼カバー部材４の割り筒部１１の側部開口１１ａが引込み溝部２８の溝底側を向いて一対の受け片１５の先端が引込み溝部２８の溝底に当接するように仮収容溝３２内に収容する。また、他方の床パネル２３Ｂの配管１７の他端部に接続した抜け止め兼カバー部材４を取付けた雄継手部材２を仮収容溝３２から取り出して配管１７の余長部分と共に引出し口２５から外に引き出す。   When the fitting connection is completed, the female joint member 3 and the male joint member 2 whose connecting portions are covered with the retaining and covering member 4 are arranged in the drawing groove portion 28 of the other floor panel 23B. In this case, the side opening 11 a of the split cylinder portion 11 of the retaining / cover member 4 faces the groove bottom side of the retracting groove portion 28 so that the tips of the pair of receiving pieces 15 are in contact with the groove bottom of the retracting groove portion 28. Housed in the housing groove 32. Further, the male joint member 2 to which the retaining and covering member 4 connected to the other end portion of the pipe 17 of the other floor panel 23B is attached is taken out from the temporary housing groove 32 and removed from the drawing port 25 together with the extra length portion of the pipe 17. Pull out.

この状態で、他方の床パネル２３Ｂの下面の均熱板２３ｃで覆ってない床パネル２３Ｂの引出し口２５付近から仮収容溝３２に至る下面領域Ｅ、及び引込み口２６から引込み溝部２８に至る下面領域Ｆを覆うように、それぞれアルミ箔のような均熱シート３５ａ、３５ｂを貼着する（図１４参照）。   In this state, the lower surface area E extending from the vicinity of the drawer opening 25 of the floor panel 23B not covered by the heat equalizing plate 23c on the lower surface of the other floor panel 23B to the temporary housing groove 32, and the lower surface extending from the inlet 26 to the drawing groove 28. Soaking sheets 35a and 35b such as aluminum foil are attached so as to cover the region F (see FIG. 14).

次に、他方の床パネル２３Ｂを均熱板２３ｃが下となるように図１２の矢印イのように上下反転して下地板３４上に載置し、矢印ロ方向に移動させると共にハ方向に移動させることで一方の床パネル２３Ａの配管１７の外に引き出していた余長部分を引出し口２５から内部に押し込み、余長部分を第２の凹み部３０ｂの内面４０ｂ、第１の凹み部３０ａの内面４０ａに沿って押し当てて収納する。   Next, the other floor panel 23B is turned upside down as shown by the arrow A in FIG. 12 so that the heat equalizing plate 23c faces down, and is placed on the base plate 34, moved in the direction of arrow B, and moved in the direction C. The extra length portion that has been drawn out of the pipe 17 of the one floor panel 23A is pushed into the interior from the drawer port 25 by moving, and the extra length portion is pushed into the inner surface 40b of the second recess portion 30b and the first recess portion 30a. The inner surface 40a is pressed against and stored.

上記他方の床パネル２３Ｂは接着剤４５やその他の固着手段で下地板３４に固着する。この場合、床パネル２３の側端面に雄実や雌実を設けて実結合を併用するようにしてもよい。   The other floor panel 23B is fixed to the base plate 34 with an adhesive 45 or other fixing means. In this case, a male or female fruit may be provided on the side end surface of the floor panel 23 to use the actual connection together.

次に、３番目以降の床パネル２３を同様にして雄継手部材２、雌継手部材３を嵌め込み接続すると共に下地板３４に固着して敷設する。このようにして床パネル２３に設けた配管１７同士を本発明の管継手１を用いて接続すると共に、床パネル２３を敷設することで、床暖房の配管システムを施工するのである。   Next, the third and subsequent floor panels 23 are fitted and connected to the male joint member 2 and the female joint member 3 in the same manner, and fixed and laid on the base plate 34. Thus, while connecting the piping 17 provided in the floor panel 23 using the pipe joint 1 of this invention, laying the floor panel 23 constructs a floor heating piping system.

このような床暖房の配管システムにおいて、配管１７を内装した床パネル２３を工場で生産して、出荷から現場において床パネル２３同士の配管１７を接続するまでの間、配管１７の一端部に接続している雄継手部材２に設けたＯリング７が傷付いたり、異物が付着したりしないように抜け止め兼カバー部材４で保護してあるので、雄筒部８と雌筒部１０とは傷付いたり、異物が付着していないＯリング７を介して嵌め込み接続されることになり、嵌め込み接続部分における配管１７内を流れる熱媒である流体漏れが生じないようにできる。   In such a floor heating piping system, the floor panel 23 with the piping 17 is produced in the factory and connected to one end of the piping 17 from the shipment until the piping 17 between the floor panels 23 is connected at the site. Since the O-ring 7 provided on the male joint member 2 is protected by the retaining and cover member 4 so that the O-ring 7 is not damaged or foreign matter adheres, the male tube portion 8 and the female tube portion 10 are By fitting and connecting through the O-ring 7 to which no damage or foreign matter is attached, it is possible to prevent fluid leakage that is a heat medium flowing in the pipe 17 at the fitting and connecting portion.

また、接続が完了して引込み溝部２８内に配置された雌継手部材３と雄継手部材２は、抜け止め兼カバー部材４により接続部分が覆われており、しかも引込み口２６から引込み溝部２８に至る下面領域Ｆを覆う均熱シート３５ｂに断面略Ｃ字状の割り筒部１１の外周面が接触するので、金属製の割り筒部１１を介して雌継手部材３と雄継手部材２との接続部分の熱を効果的に均熱シート３５ｂに伝え、床パネル２３表面に効果的に熱伝導するようになっている。   In addition, the connecting portion of the female joint member 3 and the male joint member 2 arranged in the drawing groove portion 28 after the connection is completed is covered with the retaining and covering member 4, and the drawing portion 26 is connected to the drawing groove portion 28. Since the outer peripheral surface of the split cylinder portion 11 having a substantially C-shaped cross section is in contact with the soaking sheet 35b that covers the lower surface region F, the female joint member 3 and the male joint member 2 are connected via the metal split cylinder portion 11. The heat of the connecting portion is effectively transmitted to the soaking sheet 35b, and is effectively conducted to the surface of the floor panel 23.

また、下面領域Ｅ部分においてもこの下面領域Ｅを覆う均熱シート３５ａを介して配管１７の熱を床パネル２３表面に効果的に熱伝導することができるようにしてある。   In addition, the heat of the pipe 17 can be effectively conducted to the surface of the floor panel 23 via the soaking sheet 35a covering the lower surface region E also in the lower surface region E.
