従来、建物内の給水配管工法として、例えば壁内に設けられた水栓ボックスに、ヘッダーから伸びる鞘管を接続することにより、該鞘管内に通された給水管を水栓ボックスに設けられた給水栓に接続する鞘管ヘッダー工法が知られている（例えば、特許文献１乃至２参照。）。 Conventionally, as a water supply piping method in a building, for example, by connecting a sheath pipe extending from a header to a faucet box provided in a wall, a water supply pipe passed through the sheath pipe is provided in the faucet box. A sheath pipe header method for connecting to a water tap is known (for example, see Patent Documents 1 and 2).
水栓ボックスには、鞘管の挿入を許す筒状の挿入部が設けられている。鞘管の外周面には、凹部が形成されており、挿入部の周壁には、該周壁から挿入部の内方へ突出する係止爪が形成されている。鞘管を筒部材内に挿入し、鞘管に形成された凹部に挿入部の係止爪を係止させることにより、鞘管を水栓ボックスに接続することができる。 The faucet box is provided with a cylindrical insertion portion that allows insertion of a sheath tube. A concave portion is formed on the outer peripheral surface of the sheath tube, and a locking claw protruding from the peripheral wall to the inside of the insertion portion is formed on the peripheral wall of the insertion portion. The sheath tube can be connected to the faucet box by inserting the sheath tube into the cylindrical member and locking the retaining claws of the insertion portion in the recess formed in the sheath tube.
鞘管は、例えばその使用目的に応じて外径の大きさが異なり、このため、施工現場では、外径の異なる鞘管毎に専用の水栓ボックスが用意される。
しかしながら、鞘管毎に専用の水栓ボックスが用意されることから、例えば施工現場で用意された鞘管を、その外径よりも小さい外径を有する他の鞘管に急遽取り替える必要がある場合、前記他の鞘管に形成された凹部に挿入部の係止爪を係合することができず、水栓ボックスに前記他の鞘管を接続することができない。水栓ボックスを、前記他の鞘管に適合する他の水栓ボックスに取り替えることが考えられるが、水栓ボックスを施工現場で急遽取り替える場合には、施工現場に前記他の水栓ボックスが用意されていないことが多く、水栓ボックスを取り替えることができず、また、前記他の水栓ボックスが施工現場にたとえ用意されていたとしても、建物に既に組み付けられた水栓ボックスを前記他の水栓ボックスに組み付け替えるのに手間がかかり、施工時間の延長を招く。 However, since a dedicated faucet box is prepared for each sheath tube, for example, it is necessary to quickly replace the sheath tube prepared at the construction site with another sheath tube having an outer diameter smaller than the outer diameter. The engaging claw of the insertion portion cannot be engaged with the recess formed in the other sheath tube, and the other sheath tube cannot be connected to the faucet box. It is conceivable to replace the faucet box with another faucet box that is compatible with the other sheath tube. However, if the faucet box is to be replaced quickly at the construction site, the other faucet box is prepared at the construction site. In many cases, the faucet box cannot be replaced, and even if the other faucet box is prepared at the construction site, the faucet box already assembled in the building is not attached to the other faucet box. It takes time and effort to reassemble the faucet box, leading to extended construction time.
そこで、本発明の目的は、鞘管の外径が変更された場合でも、水栓ボックスを取り替えることなく鞘管を水栓ボックスに容易に接続することができる鞘管接続部材を提供することにある。 An object of the present invention, even when the outer diameter of the sheath tube is changed, providing a sleeve pipe connection member which can be easily connected to the sheath tube faucet box without replacing the faucet Box It is in.

このため、例えば施工現場で用意された鞘管を、その外径よりも小さい外径を有する他の鞘管に急遽取り替える必要がある場合、筒部材内に前記他の鞘管を挿入して該鞘管の環状凹部に筒部材の突起部を係合させ、筒部材を挿入部内に挿入して挿入部の係止爪を筒部材の凹部に係合させることにより、建物に既に組み付けられた水栓ボックス、すなわち、前記他の鞘管に適合しない水栓ボックスに、前記他の鞘管を筒部材を介して接続することができる。
According to the first aspect of the present invention, the sheath tube connecting member includes a tubular member that allows insertion of the sheath tube and is fitted into a tubular insertion portion provided in the faucet box. A concave portion is formed on the outer peripheral surface to be engaged with a locking claw formed on the insertion portion when the cylindrical member is fitted to the insertion portion, and a sheath into the cylindrical member is formed on the inner peripheral surface of the cylindrical member. A protrusion that protrudes inward of the cylindrical member from the inner peripheral surface is formed to engage with the annular recess of the sheath tube in the inserted state of the tube .
For this reason, for example, when it is necessary to quickly replace the sheath tube prepared at the construction site with another sheath tube having an outer diameter smaller than the outer diameter, the other sheath tube is inserted into the cylindrical member and the sheath tube is inserted.

As shown in FIG. 2, each locking claw 26 is formed of a material that can be elastically deformed. Further, in the illustrated example, the respective locking claws 26 are arranged at equal intervals along the circumferential direction of the locking member 22 at the other end portion 27 of the locking member 22. The other end 27 extends in the axial direction of the locking member 22 along the inner peripheral surface 24a of the locking member 22. A locking portion 28 that is engaged with each annular recess 13 b of the sheath tube 13 is formed at the tip 26 a of each locking claw 26.
Each locking portion 28 protrudes from the tip 26 a of each locking claw 26 toward the inside of the locking member 22.
更に、本発明に係る鞘管接続構造１０は、鞘管１３をその外径よりも大きい外径を有する鞘管に適合する水栓ボックス１１に接続するための鞘管接続部材２９を備える。 Furthermore, the sheath tube connection structure 10 according to the present invention includes a sheath tube connection member 29 for connecting the sheath tube 13 to the faucet box 11 adapted to the sheath tube having an outer diameter larger than the outer diameter.
鞘管接続部材２９は、図２に示すように、鞘管１３の挿通を許し且つ水栓ボックス１１の挿入部１５に嵌合される円筒状の筒部材３０を備える。 As shown in FIG. 2, the sheath tube connecting member 29 includes a cylindrical tube member 30 that allows the sheath tube 13 to be inserted and is fitted to the insertion portion 15 of the faucet box 11.
筒部材３０の外周面３０ａには、挿入部１５の係止部材２２の各係止爪２６に係止される複数の凹部３１が形成されている。各凹部３１は、図示の例では、筒部材３０の軸線に沿って互いに間隔をおき且つ筒部材３０の周方向に廻るように、筒部材３０の外周面３０ａに形成されている。 On the outer peripheral surface 30 a of the cylindrical member 30, a plurality of recesses 31 that are locked to the locking claws 26 of the locking member 22 of the insertion portion 15 are formed. In the illustrated example, the recesses 31 are formed on the outer peripheral surface 30 a of the cylindrical member 30 so as to be spaced apart from each other along the axis of the cylindrical member 30 and to turn in the circumferential direction of the cylindrical member 30.
また、筒部材３０の内周面３０ｂには、筒部材３０内への鞘管１３の挿入状態で該鞘管の環状凹部１３ｂに係合可能な複数の突起部３２が形成されている。各突起部３２は、図示の例では、筒部材３０の両端部及び筒部材３０の長手方向の中央部のそれぞれに筒部材３０の周方向に伸びるように形成されている。各突起部３２の先端３２ａは、図示の例では、半球状をなしている。また、各突起部３２の間隔は、鞘管１３の外周面１３ａに形成された各環状凹部１３ｂの間隔の整数倍の大きさになるように設定されている。 In addition, a plurality of protrusions 32 that can be engaged with the annular recess 13 b of the sheath tube when the sheath tube 13 is inserted into the tubular member 30 are formed on the inner peripheral surface 30 b of the tubular member 30. In the illustrated example, each protrusion 32 is formed so as to extend in the circumferential direction of the tubular member 30 at both ends of the tubular member 30 and the longitudinal central portion of the tubular member 30. The tip 32a of each projection 32 is hemispherical in the illustrated example. Further, the interval between the protrusions 32 is set to be an integral multiple of the interval between the annular recesses 13 b formed on the outer peripheral surface 13 a of the sheath tube 13.
この鞘管接続部材２９を用いて鞘管１３を水栓ボックス１１に接続する際、先ず、鞘管１３の先端部を筒部材３０内に挿入し、筒部材３０の内周面３０ｂに形成された各突起部３２を、鞘管１３の外周面１３ａに形成された複数の環状凹部１３ｂ…のうち、各突起部３２に対応する環状凹部１３ｂに係合させる。このとき、前記したように、各突起部３２の先端３２ａが半球状をなしていることから、筒部材３０内への鞘管１３の挿入時に鞘管１３が各突起部３２から受ける摩擦力を低減させることができる。これにより、筒部材３０内への鞘管１３の挿入を容易に行うことができる。 When connecting the sheath tube 13 to the faucet box 11 using the sheath tube connecting member 29, first, the distal end portion of the sheath tube 13 is inserted into the tubular member 30 and formed on the inner peripheral surface 30 b of the tubular member 30. Each projection 32 is engaged with an annular recess 13b corresponding to each projection 32 among the plurality of annular recesses 13b formed on the outer peripheral surface 13a of the sheath tube 13. At this time, as described above, the tip 32a of each projection 32 has a hemispherical shape, and therefore, the frictional force that the sheath tube 13 receives from each projection 32 when the sheath tube 13 is inserted into the cylindrical member 30 is obtained. Can be reduced. Thereby, insertion of the sheath pipe | tube 13 in the cylinder member 30 can be performed easily.
次に、鞘管１３に取り付けられた筒部材３０を水栓ボックス１１の挿入部１５の係止部材２２内に挿入し、該係止部材に形成された各係止爪２６の係止部２８を筒部材３０の外周面３０ａに形成された各凹部３１のうち、何れか一つに係合させる。これにより、鞘管１３は係止部材２２に筒部材３０を介して固定され、これにより、鞘管１３は水栓ボックス１１に鞘管接続部材２９を介して接続される。 Next, the cylindrical member 30 attached to the sheath tube 13 is inserted into the locking member 22 of the insertion portion 15 of the faucet box 11, and the locking portion 28 of each locking claw 26 formed on the locking member. Is engaged with any one of the recesses 31 formed on the outer peripheral surface 30 a of the cylindrical member 30. As a result, the sheath tube 13 is fixed to the locking member 22 via the tubular member 30, whereby the sheath tube 13 is connected to the faucet box 11 via the sheath tube connecting member 29.
本実施例によれば、前記したように、鞘管接続部材２９は、鞘管１３の挿入を許し且つ水栓ボックス１１に設けられた筒状の挿入部１５内に嵌合される筒部材３０を備え、該筒部材の外周面３０ａに、挿入部１５への筒部材３０の嵌合状態で、挿入部１５に形成された係止爪２６に係合する凹部３１が形成されており、筒部材３０の内周面３０ｂに、筒部材３０内への鞘管１３の挿入状態で該鞘管１３の環状凹部１３ｂに係合すべく内周面３０ｂから筒部材３０の内方に突出する突起部３２が形成されている。 According to the present embodiment, as described above, the sheath tube connecting member 29 allows the insertion of the sheath tube 13 and is fitted into the tubular insertion portion 15 provided in the faucet box 11. A concave portion 31 is formed on the outer peripheral surface 30a of the cylindrical member so as to be engaged with a locking claw 26 formed in the insertion portion 15 in a fitted state of the cylindrical member 30 with the insertion portion 15. the inner peripheral surface 30b of the member 30, the projections projecting from the inner peripheral surface 30b to engage the annular recess 13b of the sheath tube 13 in inserted state of the sheath pipe 13 to the cylindrical member 30 within the interior of the cylindrical member 30 A portion 32 is formed.
これにより、例えば施工現場で用意された鞘管１３を、その外径よりも小さい外径を有する他の鞘管に急遽取り替える必要がある場合、筒部材３０内に前記他の鞘管を挿入して該鞘管１３の環状凹部１３ｂに筒部材３０の突起部３２を係合させ、筒部材３０を挿入部１５内に挿入して挿入部１５の係止爪２６を筒部材３０の凹部３１に係合させることにより、建物に既に組み付けられた水栓ボックス１１すなわち前記他の鞘管に適合しない水栓ボックス１１に前記他の鞘管を筒部材３０を介して接続することができる。 Thereby, for example, when it is necessary to quickly replace the sheath tube 13 prepared at the construction site with another sheath tube having an outer diameter smaller than the outer diameter, the other sheath tube is inserted into the cylindrical member 30. Then, the protrusion 32 of the cylindrical member 30 is engaged with the annular recess 13 b of the sheath tube 13 , the cylindrical member 30 is inserted into the insertion portion 15, and the locking claw 26 of the insertion portion 15 is inserted into the recess 31 of the cylindrical member 30. By engaging, the other sheath pipe can be connected to the faucet box 11 already assembled in the building, that is, the faucet box 11 that is not compatible with the other sheath pipe, via the tubular member 30.
従って、鞘管１３の外径の変更時に、建物に既に組み付けられた水栓ボックス１１を他の水栓ボックス１１に取り替える必要はないので、水栓ボックス１１を組み付け替えることによる従来のような施工時間の延長を招くことなく、建物に既に組み付けられた水栓ボックス１１に前記他の鞘管を容易に接続することができる。 Therefore, when the outer diameter of the sheath tube 13 is changed, it is not necessary to replace the faucet box 11 already assembled in the building with another faucet box 11, so that the conventional construction by reassembling the faucet box 11 is performed. The other sheath tube can be easily connected to the faucet box 11 already assembled in the building without incurring time extension.
また、前記したように、鞘管１３の各環状凹部１３ｂ…が、鞘管１３をその周方向に沿って廻るように形成されており、筒部材３０の内周面３０ｂに形成された各突起部３２が、それぞれ筒部材３０の周方向に伸びていることから、鞘管１３を例えば単一のピン状の突起部３２で係止する場合に比べて、鞘管１３への突起部３２の係止力を高めることができるので、鞘管１３を筒部材３０内により確実に保持することができる。 Further, as described above, each annular recess 13b... Of the sheath tube 13 is formed so as to go around the sheath tube 13 along its circumferential direction, and each projection formed on the inner peripheral surface 30b of the cylindrical member 30. Since the portions 32 extend in the circumferential direction of the cylindrical member 30, compared to the case where the sheath tube 13 is locked by, for example, a single pin-like projection portion 32, the projection portion 32 to the sheath tube 13 is Since the locking force can be increased, the sheath tube 13 can be reliably held in the cylindrical member 30.
更に、前記したように、複数の突起部３２が筒部材３０の軸線に沿って互いに間隔をおいて形成されていることから、筒部材３０に単一の突起部３２が形成された場合に比べて鞘管１３の何れか一つの環状凹部１３ｂへの突起部３２の係合位置の自由度を高めることができるので、鞘管１３を筒部材３０内に所望の挿入位置で保持することができる。
また、複数の突起部３２が筒部材３０の軸線に沿って互いに間隔をおいて形成されていることから、筒部材３０の複数の突起部３２のうち一つの突起部３２と鞘管１３の環状凹部１３ｂとの係合がたとえ解除されたとしても、環状凹部１３ｂを他の突起部３２に係合させることができるので、挿入部１５内からの鞘管１３の抜出しをより確実に防止することができる。
Furthermore, as described above, the plurality of protrusions 32 are formed at intervals from each other along the axis of the cylindrical member 30, so that compared to the case where the single protrusion 32 is formed on the cylindrical member 30. Therefore, the degree of freedom of the engagement position of the projection 32 to any one annular recess 13b of the sheath tube 13 can be increased, so that the sheath tube 13 can be held in the cylindrical member 30 at a desired insertion position. .
Further, since the plurality of protrusions 32 are formed at intervals from each other along the axis of the cylindrical member 30, one of the plurality of protrusions 32 of the cylindrical member 30 and the annular ring of the sheath tube 13.
