特開平６−１３４６７８号公報JP-A-6-134678

上記した従来例のように、パイプ、さや管、保温材を固定する用途として、市場に出ている部材(サドル）は存在するが、継手のみを固定する用途としての部材は存在しない。先分岐工法の場合、現状では継手付近のパイプを、壁や床等の取付け部に固定するしかないが、継手付近ではパイプが取付け部から浮いているため固定しにくい。また、パイプを固定するとパイプに負荷がかかる。更に、施工の指示によっては、継手付近のパイプをすべて固定するようになり、固定箇所が多い。   As in the conventional example described above, there are members (saddles) on the market for fixing pipes, sheaths, and heat insulating materials, but there are no members for fixing only joints. In the case of the pre-branch method, at present, the pipe near the joint can only be fixed to the mounting portion such as a wall or floor, but it is difficult to fix because the pipe floats from the mounting portion near the joint. Moreover, when the pipe is fixed, a load is applied to the pipe. Furthermore, depending on the construction instructions, all the pipes near the joint are fixed, and there are many fixing points.

本発明は、上記事実を考慮して、継手自体を取付け部に固定できるようにすると共に、継手の固定についての作業性を高めることを目的とする。   In consideration of the above facts, the present invention is intended to enable the joint itself to be fixed to the mounting portion and to improve workability for fixing the joint.

以下、本発明を実施するための形態を図面に基づき説明する。図１において、本実施形態に係る継手固定器具１０は、継手２１を取付け部２４に固定するために用いられる。継手固定構造Ｓは、継手固定器具１０を用いて、継手２１を取付け部２４に固定した構造である。継手２１は、パイプ１４を挿入するための挿入部１６を内部に有する筒状の継手本体部１８と、継手本体部１８のパイプ挿入開口側外表面に取り付けられるキャップ部３０と、を備えている。この継手２１は、所謂チーズであり、平面視でＴ字形に形成され、３方に例えばポリブテン製のパイプ１４を接続可能となっている。キャップ部３０としては、矢印Ｙ方向を軸方向とする第１キャップ部３１と、矢印Ｘ方向を軸方向とし互いに逆向きに配置される第２キャップ部３２及び第３キャップ部３３とが設けられている。図１，図２に示されるように、継手固定器具１０は、第１アーム部１１と、第２アーム部１２とを有している。   Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In FIG. 1, the joint fixing device 10 according to the present embodiment is used for fixing a joint 21 to a mounting portion 24. The joint fixing structure S is a structure in which the joint 21 is fixed to the attachment portion 24 using the joint fixing device 10. The joint 21 includes a tubular joint main body 18 having an insertion portion 16 for inserting the pipe 14 therein, and a cap portion 30 attached to the pipe insertion opening side outer surface of the joint main body 18. . This joint 21 is so-called cheese, is formed in a T shape in a plan view, and can be connected to a pipe 14 made of, for example, polybutene in three directions. The cap part 30 includes a first cap part 31 having the arrow Y direction as an axial direction, and a second cap part 32 and a third cap part 33 arranged in opposite directions with the arrow X direction as an axial direction. ing. As shown in FIGS. 1 and 2, the joint fixing device 10 includes a first arm portion 11 and a second arm portion 12.

第１アーム部１１は、２本設けられており、少なくとも１本は、第２キャップ部３２又は第３キャップ部３３への当接部となっている。図１，図２に示される例では、第２キャップ部３２と第３キャップ部３３とが同軸上にあり、かつ各々の外径が等しい。従って、一方の第１アーム部１１を第２キャップ部３２に当接させると共に、他方の第１アーム部１１を第３キャップ部３３に当接させることができる。キャップ部３０（第２キャップ部３２と第３キャップ部３３）が同軸上にない場合や、各々の外径が異なる異径継手の場合には、どちらか一方の第１アーム部１１を、外径が大きい側のキャップ部３０に当接させることとなる。   Two first arm portions 11 are provided. At least one first arm portion 11 serves as a contact portion with respect to the second cap portion 32 or the third cap portion 33. In the example shown in FIGS. 1 and 2, the second cap portion 32 and the third cap portion 33 are coaxial, and the outer diameters are the same. Accordingly, one first arm portion 11 can be brought into contact with the second cap portion 32 and the other first arm portion 11 can be brought into contact with the third cap portion 33. When the cap part 30 (the second cap part 32 and the third cap part 33) is not coaxial, or in the case of different diameter joints having different outer diameters, either one of the first arm parts 11 is The cap portion 30 on the side having a larger diameter is brought into contact with the cap portion 30.

第１アーム部１１の各々の先端には、取付け部２４に対する固定部４１が設けられている。この固定部４１は、第１アーム部１１の先端から矢印Ｙ方向（＋Ｙ方向）に張り出して形成されている。各々の固定部４１には、ねじ２６を通すための貫通孔２８が、例えば１箇所ずつ設けられている。ねじ止めにおける作業性の観点から、固定部４１の貫通孔２８の位置は、第１アーム部１１からある程度離れていた方がよい。   A fixing portion 41 for the attachment portion 24 is provided at the tip of each first arm portion 11. The fixing portion 41 is formed to protrude from the tip of the first arm portion 11 in the arrow Y direction (+ Y direction). Each fixing portion 41 is provided with, for example, one through hole 28 through which the screw 26 passes. From the viewpoint of workability in screwing, it is preferable that the position of the through hole 28 of the fixing portion 41 be separated from the first arm portion 11 to some extent.

図２に示されるように、２本の第１アーム部１１は、第１キャップ部３１の径方向両側に位置するように構成されている。この２本の第１アーム部１１は、互いに平行に対向する平行部１１Ａを有している。平行部１１Ａは、図１の矢印Ｚ方向に沿って夫々直線状に形成されている。図２に示されるように、平行部１１Ａの間隔Ｄは、第１キャップ部３１の外径ｄ以上である。第１キャップ部３１の外径は位置によって異なるが、図示の例では、第１アーム部１１は最大外径の位置の径方向両側に位置する。従って、ここでの外径ｄとは、最大外径である。第１アーム部１１が対応する部分の外径が最大外径でない場合には、その外径を外径ｄとする。つまり、平行部１１Ａの間隔Ｄは、第１キャップ部３１のうち、第１アーム部１１が位置する部分の外径ｄ以上であればよい。   As shown in FIG. 2, the two first arm portions 11 are configured to be located on both radial sides of the first cap portion 31. The two first arm portions 11 have parallel portions 11A that face each other in parallel. Each of the parallel portions 11A is formed in a straight line along the arrow Z direction in FIG. As shown in FIG. 2, the interval D between the parallel portions 11 </ b> A is equal to or larger than the outer diameter d of the first cap portion 31. Although the outer diameter of the first cap portion 31 varies depending on the position, in the illustrated example, the first arm portion 11 is located on both sides in the radial direction of the position of the maximum outer diameter. Therefore, the outer diameter d here is the maximum outer diameter. When the outer diameter of the portion corresponding to the first arm portion 11 is not the maximum outer diameter, the outer diameter is set as the outer diameter d. That is, the interval D between the parallel portions 11A may be equal to or greater than the outer diameter d of the portion of the first cap portion 31 where the first arm portion 11 is located.

図１，図２において、第２アーム部１２は、例えば１本設けられ、第１アーム部１１から継手２１を跨ぐように第１アーム部１１と逆方向に延び、継手本体部１８への当接部となる。また、継手固定器具１０は、第１アーム部１１の先端と、第２アーム部１２の先端との間隔が変化する方向に弾性を有している。第２アーム部１２の幅Ｗは、弾性を得るために、第１アーム部１１よりも幅狭に形成されている。また、第２アーム部１２の幅Ｗは、第２キャップ部３２と第３キャップ部３３との間隔Ｌよりも狭く設定されている。これは、継手本体部１８が、第２キャップ部３２や第３キャップ部３３の外径よりも小径とされており、第２アーム部１２の幅をこのように設定しないと、該第２アーム部１２を継手本体部１８に当接させることが難しくなるためである。   In FIG. 1 and FIG. 2, for example, one second arm portion 12 is provided, extends from the first arm portion 11 in a direction opposite to the first arm portion 11 so as to straddle the joint 21, and contacts the joint main body portion 18. It becomes a contact part. Further, the joint fixing device 10 has elasticity in the direction in which the distance between the tip of the first arm portion 11 and the tip of the second arm portion 12 changes. The width W of the second arm portion 12 is narrower than that of the first arm portion 11 in order to obtain elasticity. In addition, the width W of the second arm portion 12 is set to be narrower than the interval L between the second cap portion 32 and the third cap portion 33. This is because the joint body 18 has a smaller diameter than the outer diameters of the second cap part 32 and the third cap part 33, and the second arm 12 must be set in this way unless the width of the second arm part 12 is set. This is because it is difficult to bring the portion 12 into contact with the joint body portion 18.

継手固定器具１０は、例えば樹脂の一体成型品であり、第１アーム部１１と第２アーム部１２は、矢印Ｚ方向に最も高い位置である頂上部３４で繋がっている。換言すれば、第２アーム部１２から頂上部３４までは１本で形成され、該頂上部３４から二股に分かれて第１アーム部１１が形成されている。矢印Ｙ方向において、第２アーム部１２は、２本の第１アーム部１１の中間に位置している。   The joint fixture 10 is, for example, an integrally molded product of resin, and the first arm portion 11 and the second arm portion 12 are connected by a top portion 34 that is the highest position in the arrow Z direction. In other words, the second arm portion 12 to the top portion 34 are formed as a single piece, and the first arm portion 11 is formed by being divided into two branches from the top portion 34. In the arrow Y direction, the second arm portion 12 is located in the middle of the two first arm portions 11.

第２アーム部１２の先端には、取付け部２４に対する固定部４２が設けられている。この固定部４２は、第２アーム部１２の先端から矢印Ｙ方向の逆方向（−Ｙ方向）に張り出して形成されている。固定部４２には、ねじ２６を通すための貫通孔２８が、例えば１箇所設けられている。第１アーム部１１の固定部４１と同様に、ねじ止めにおける作業性の観点から、固定部４２の貫通孔２８の位置は、第２アーム部１２からある程度離れていた方がよい。取付け部２４は一般に平坦であることから、固定部４１，４２の底面は、矢印Ｚ方向において同等の位置にあることが望ましい。   A fixing portion 42 for the attachment portion 24 is provided at the tip of the second arm portion 12. The fixed portion 42 is formed so as to protrude from the tip of the second arm portion 12 in the reverse direction of the arrow Y direction (−Y direction). The fixing portion 42 has, for example, one through hole 28 through which the screw 26 is passed. Similar to the fixing portion 41 of the first arm portion 11, the position of the through hole 28 of the fixing portion 42 should be somewhat away from the second arm portion 12 from the viewpoint of workability in screwing. Since the attachment portion 24 is generally flat, it is desirable that the bottom surfaces of the fixing portions 41 and 42 are in the same position in the arrow Z direction.

第１アーム部１１の第２キャップ部３２、第３キャップ部３３との当接部分の曲率は、該第２キャップ部３２、第３キャップ部３３の外周の曲率に近似していることが望ましい。同様に、第２アーム部１２の継手本体部１８との当接部分の曲率は、該継手本体部１８の外周の曲率に近似していることが望ましい。なお、第１アーム部１１及び第２アーム部１２は、必ずしも円弧形状を有していなくてもよい。第１アーム部１１側と、第２アーム部１２側とで、夫々少なくとも１点ずつ継手２１に当接すれば、該継手２１を取付け部２４に安定して固定できるためである。また、本実施形態においては、キャップ部の外径の大きさが継手本体部１８の外径よりも大きい継手を固定しているが、固定する継手は、キャップ部の外径の大きさが継手本体部１８の外径と同じ大きさに形成されていてもよく、継手本体部１８の外径より小さく形成されていてもよい。   It is desirable that the curvature of the contact portion of the first arm portion 11 with the second cap portion 32 and the third cap portion 33 approximate the curvature of the outer periphery of the second cap portion 32 and the third cap portion 33. . Similarly, it is desirable that the curvature of the contact portion of the second arm portion 12 with the joint main body portion 18 approximates the curvature of the outer periphery of the joint main body portion 18. The first arm portion 11 and the second arm portion 12 do not necessarily have an arc shape. This is because the joint 21 can be stably fixed to the mounting portion 24 if at least one point abuts on the first arm portion 11 side and the second arm portion 12 side. Moreover, in this embodiment, although the joint whose outer diameter of the cap part is larger than the outer diameter of the joint main body part 18 is fixed, the joint to be fixed has the outer diameter of the cap part as a joint. The outer diameter of the main body 18 may be the same as that of the main body 18 or may be smaller than the outer diameter of the joint main body 18.

（作用）
本実施形態は、上記のように構成されており、以下その作用について説明する。図１，図２において、継手固定器具１０を用いて継手２１を取付け部２４に固定する際、２本の第１アーム部１１と１本の第２アーム部１２が継手２１を跨いだ状態となる。このとき、２本の第１アーム部１１の少なくとも１本が継手２１の第２キャップ部３２、第３キャップ部３３に当接し、第２アーム部１２が継手本体部１８に当接する。また、２本の第１アーム部１１が、第１キャップ部３１の径方向両側に位置する。２本の第１アーム部１１における平行部１１Ａの間隔Ｄは、第１キャップ部３１の外径ｄ以上であるので、第１アーム部１１を該第１キャップ部３１の径方向両側に差し込み易い。 (Function)
This embodiment is configured as described above, and the operation thereof will be described below. 1 and 2, when the joint 21 is fixed to the mounting portion 24 using the joint fixing device 10, the two first arm portions 11 and the one second arm portion 12 straddle the joint 21. Become. At this time, at least one of the two first arm portions 11 is in contact with the second cap portion 32 and the third cap portion 33 of the joint 21, and the second arm portion 12 is in contact with the joint main body portion 18. Further, the two first arm portions 11 are located on both sides in the radial direction of the first cap portion 31. Since the distance D between the parallel portions 11A of the two first arm portions 11 is equal to or greater than the outer diameter d of the first cap portion 31, the first arm portion 11 can be easily inserted into both radial sides of the first cap portion 31. .

第１アーム部１１の先端の固定部４１と、第２アーム部１２の先端の固定部４２は、ねじ２６により取付け部２４に夫々締付固定される。これにより、継手２１自体を取付け部２４に固定することができる。継手２１自体を固定することにより、例えばポリブテン製のパイプ１４に負担をかけることがない。継手２１はパイプ１４よりも剛性が高いので、継手２１が継手固定器具１０から受ける負担は少ない。また、３本のパイプ１４を２箇所ずつ固定すると計６箇所の固定が必要となるが、本実施形態では、計３箇所の固定で済む。このため、継手２１の固定についての作業性を高めることができる。   The fixing portion 41 at the tip of the first arm portion 11 and the fixing portion 42 at the tip of the second arm portion 12 are fastened and fixed to the mounting portion 24 by screws 26, respectively. Thereby, the joint 21 itself can be fixed to the mounting portion 24. By fixing the joint 21 itself, for example, a load is not applied to the pipe 14 made of polybutene. Since the joint 21 has higher rigidity than the pipe 14, the burden on the joint 21 from the joint fixing device 10 is small. Further, if the three pipes 14 are fixed at two places, it is necessary to fix a total of six places, but in this embodiment, a total of three places may be fixed. For this reason, the workability | operativity about fixation of the coupling 21 can be improved.

継手２１の矢印Ｙ方向（＋Ｙ方向と−Ｙ方向）の動きは、第１アーム部１１と第２アーム部１２により制限される。また、第１キャップ部３１の径方向両側に位置する２本の第１アーム部１１により、該径方向（＋Ｘ方向と−Ｘ方向）における継手２１の動きが制限される。更に、継手固定器具１０により、継手２１の矢印Ｚ方向（＋Ｚ方向と−Ｚ方向）の動きも制限される。このように、継手固定器具１０により継手２１の矢印Ｘ，Ｙ，Ｚ方向の動きがすべて制限されるため、該継手２１を安定的に固定することができる。また、継手固定器具１０は、継手２１の固定時に弾性変形することにより、サイズや形状が異なる種々の継手２１に対応することができる。更に、継手固定器具１０は、チーズである継手２１に限られず、図３に示される継手２２（ストレート）、図４に示される継手２３（エルボ）にもそのまま適用できる。また、図示は省略するが、継手固定器具１０は、ストレートで両側のキャップ部３０の外径が異なる異径継手にも適用することが可能である。   The movement of the joint 21 in the arrow Y direction (+ Y direction and −Y direction) is limited by the first arm portion 11 and the second arm portion 12. Further, the movement of the joint 21 in the radial direction (+ X direction and −X direction) is restricted by the two first arm portions 11 positioned on both sides in the radial direction of the first cap portion 31. Furthermore, the joint fixture 10 also restricts the movement of the joint 21 in the arrow Z direction (+ Z direction and −Z direction). As described above, since the joint fixing device 10 restricts all movements of the joint 21 in the directions of the arrows X, Y, and Z, the joint 21 can be stably fixed. Moreover, the joint fixing device 10 can respond to various joints 21 having different sizes and shapes by elastically deforming when the joint 21 is fixed. Furthermore, the joint fixing device 10 is not limited to the joint 21 which is a cheese, but can be applied to the joint 22 (straight) shown in FIG. 3 and the joint 23 (elbow) shown in FIG. Moreover, although illustration is abbreviate | omitted, the joint fixing tool 10 can be applied also to the different diameter joint from which the outer diameter of the cap part 30 on both sides differs in a straight.

図３に示される例では、第２アーム部１２の幅Ｗが、第２キャップ部３２と第３キャップ部３３との隙間の間隔Ｌよりもわずかに狭く設定されている。第２アーム部１２は、該隙間に入り込んで継手本体部１８に当接している。この第２アーム部１２が、第２キャップ部３２や第３キャップ部３３の端面に引っ掛かることにより、継手２２の矢印Ｘ方向の動きが制限される。また、第１アーム部１１が第２キャップ部３２と第３キャップ部３３に当接し、第２アーム部１２が継手本体部１８に当接することで、継手２２の矢印Ｙ方向の動きが制限される。継手２２（ストレート）には、継手２１（チーズ）や継手２３（エルボ）における第１キャップ部３１が存在しないので、２本の第１アーム部１１の間に挟まれるキャップ部３０は存在しない。   In the example shown in FIG. 3, the width W of the second arm portion 12 is set to be slightly narrower than the gap L between the second cap portion 32 and the third cap portion 33. The second arm portion 12 enters the gap and contacts the joint main body portion 18. When the second arm portion 12 is caught by the end surfaces of the second cap portion 32 and the third cap portion 33, the movement of the joint 22 in the arrow X direction is limited. Further, the movement of the joint 22 in the arrow Y direction is restricted by the first arm portion 11 abutting on the second cap portion 32 and the third cap portion 33 and the second arm portion 12 abutting on the joint main body portion 18. The Since the joint 22 (straight) does not include the first cap portion 31 of the joint 21 (cheese) or the joint 23 (elbow), the cap portion 30 sandwiched between the two first arm portions 11 does not exist.

図４に示される例では、第１アーム部１１が第２キャップ部３２と第３キャップ部３３に当接し、第２アーム部１２が継手本体部１８に当接することで、継手２３（エルボ）の矢印Ｙ方向の動きが制限される。また、第１キャップ部３１の径方向両側に位置する２本の第１アーム部１１により、継手２３の矢印Ｘ方向の動きが制限される。
このように、本実施形態に係る継手固定器具１０は、多種類の継手２１，２２，２３の固定に適用することができる。 In the example shown in FIG. 4, the first arm portion 11 abuts on the second cap portion 32 and the third cap portion 33, and the second arm portion 12 abuts on the joint main body portion 18, thereby the joint 23 (elbow). The movement in the arrow Y direction is limited. Further, the movement of the joint 23 in the arrow X direction is restricted by the two first arm portions 11 located on both radial sides of the first cap portion 31.
Thus, the joint fixing device 10 according to the present embodiment can be applied to fixing various types of joints 21, 22, and 23.

［他の実施形態］
上記実施形態では、２本の第１アーム部１１が平行部１１Ａを有するものとしたが、該平行部１１Ａを設けなくてもよい。また、２本の第１アーム部１１の互いに対向する面に起伏があってもよい。また、第２アーム部１２が１本であるものとしたが、これに限られず、第２アーム部１２にスリットを設けて、外観上２本に見えるようにしてもよい。更には、第２アーム部１２を複数本としつつ、各第２アーム部１２の先端を１箇所の固定部４２に集合させる構成であってもよい。 [Other Embodiments]
In the above embodiment, the two first arm parts 11 have the parallel part 11A, but the parallel part 11A may not be provided. Further, the surfaces of the two first arm portions 11 facing each other may be undulated. Moreover, although the 2nd arm part 12 shall be one, it is not restricted to this, You may make it look like two by providing a slit in the 2nd arm part 12 in an external appearance. Furthermore, the structure which makes the front-end | tip of each 2nd arm part 12 gather to the one fixing | fixed part 42 may be sufficient as the 2nd arm part 12 being made into multiple pieces.

継手固定器具１０において、第１アーム部１１の先端と第２アーム部１２の先端との間隔が変化する方向に弾性を持たせるために、ばねで付勢されたヒンジを介して第１アーム部１１と第２アーム部１２とを連結してもよい。また、第１アーム部１１及び第２アーム部１２の一方を金属で構成し、他方を樹脂、ゴム、エラストマー等の弾性体で構成してもよい。もっとも、継手固定器具１０が、上記のような弾性を有しない構成とすることも可能である。   In the joint fixing device 10, in order to give elasticity in the direction in which the distance between the tip of the first arm portion 11 and the tip of the second arm portion 12 changes, the first arm portion is interposed via a spring biased spring. 11 and the second arm portion 12 may be connected. Alternatively, one of the first arm portion 11 and the second arm portion 12 may be made of metal, and the other may be made of an elastic body such as resin, rubber, or elastomer. However, it is also possible for the joint fixing device 10 to have a configuration that does not have elasticity as described above.
