Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 2 to 4, the pipe joint 1 is attached to the wall body 100 as a structure. In the wall body 100, a through hole 103 is formed between the first surface 101 and the second surface 102. The pipe joint 1 is inserted and arranged in the through hole 103, and supplies the hot water received on the first surface 101 side to the second surface 102 side.

図1は、管継手1を、軸線Lに沿う方向へと分解して示す斜視図である。図1おいて壁体100の第一面101側に位置しているのは、第一面101から遠い順に、継手本体2を構成するエルボ部材9、継手本体2のフランジ部をなすフランジ部材3、中間リング4、及び止水リング5である。図1において壁体100の第二面102側に位置しているのは、第二面102に対して遠い順に、ピン状の固定部材としての複数本(本実施形態においては2本)のビス8、固定リング7、滑りリング6、及び止水リング10である。 FIG. 1 is a perspective view showing the pipe joint 1 disassembled in the direction along the axis L. In FIG. 1, the elbow members 9 constituting the joint body 2 and the flange members 3 forming the flanges of the joint body 2 are located on the first surface 101 side of the wall body 100 in the order of distance from the first surface 101. , An intermediate ring 4, and a water stop ring 5. In FIG. 1, a plurality of (two in this embodiment) screws as pin-shaped fixing members are located on the second surface 102 side of the wall body 100 in the order of distance from the second surface 102. 8, a fixing ring 7, a sliding ring 6, and a water blocking ring 10.

図1及び図3に示すように、エルボ部材9は、筒状部20と管接続部21とがL字形に配置されてなる。筒状部20と管接続部21とは内部が連通されている。筒状部20の外周面には雄ねじ部22が形成されている。筒状部20の内周面には雌ねじ部23が形成されている。 As shown in FIGS. 1 and 3, the elbow member 9 has a tubular portion 20 and a pipe connecting portion 21 arranged in an L shape. The inside of the tubular portion 20 and the pipe connecting portion 21 are communicated with each other. A male screw portion 22 is formed on the outer peripheral surface of the tubular portion 20. A female screw portion 23 is formed on the inner peripheral surface of the tubular portion 20.

管接続部21は、周知のワンタッチ継手よりなっている。管接続部21には、例えば架橋ポリエチレンやポリブテン等の合成樹脂製の管体Pが接続される。筒状部20の雌ねじ部23には、例えば水栓等の配管部材(図示しない)が接続される。 The pipe connecting portion 21 is made of a well-known one-touch joint. A pipe body P made of a synthetic resin such as cross-linked polyethylene or polybutene is connected to the pipe connecting portion 21. A piping member (not shown) such as a faucet is connected to the female screw portion 23 of the tubular portion 20.

図1、図2及び図4に示すように、雄ねじ部22には、一対の平面部24(第一規制部)が形成されている。一対の平面部24は、互いに平行となるように筒状部20の軸線を挟んで反対側に形成されている。 As shown in FIGS. 1, 2 and 4, a pair of flat surface portions 24 (first regulating portions) are formed on the male screw portion 22. The pair of flat surface portions 24 are formed on opposite sides of the axial line of the tubular portion 20 so as to be parallel to each other.

図3及び図4に示すように、筒状部20の基端側にはフランジ部材3が取り付けられている。フランジ部材3の内周面には、雄ねじ部22に螺合する雌ねじ部30が形成されている。フランジ部材3は筒状部20の基端側まで螺進されている。 As shown in FIGS. 3 and 4, a flange member 3 is attached to the base end side of the tubular portion 20. A female threaded portion 30 screwed into the male threaded portion 22 is formed on the inner peripheral surface of the flange member 3. The flange member 3 is screwed to the base end side of the tubular portion 20.

図3及び図4に示すように、筒状部20にフランジ部材3を螺合した後、筒状部20に中間リング4及び止水リング5を挿入する。 As shown in FIGS. 3 and 4, after the flange member 3 is screwed into the tubular portion 20, the intermediate ring 4 and the water stop ring 5 are inserted into the tubular portion 20.

図1及び図4に示すように、中間リング4の内周面には、筒状部20に対応する形状をした挿通孔40と、雄ねじ部22に形成された一対の平面部24に対応する形状をした一対の板部41(第二規制部)とが形成されている。つまり、挿通孔40に筒状部20を挿通させた状態で、筒状部20を周方向に回転させると、平面部24と板部41とが当たって連れ回りする関係となっている。 As shown in FIGS. 1 and 4, the inner peripheral surface of the intermediate ring 4 corresponds to an insertion hole 40 having a shape corresponding to the tubular portion 20 and a pair of flat surfaces 24 formed in the male screw portion 22. A pair of shaped plate portions 41 (second regulating portion) are formed. That is, when the tubular portion 20 is rotated in the circumferential direction with the tubular portion 20 inserted through the insertion hole 40, the flat surface portion 24 and the plate portion 41 are in contact with each other and rotate around.

中間リング4は、ステンレス板や鋼板等をプレスして形成されている。中間リング4の外形形状に沿ってプレスした後、内側にできた2つの平面突部を外側に折り曲げることによって、板部41が形成されている。 The intermediate ring 4 is formed by pressing a stainless plate, a steel plate, or the like. After pressing along the outer shape of the intermediate ring 4, the plate portion 41 is formed by bending the two planar protrusions formed inside to the outside.

図1に示すように、止水リング5は、平板リング状のパッキンであり、軟質の合成樹脂やゴム等で形成されている。止水リング5には、筒状部20が挿通可能な挿通孔50が形成されている。 As shown in FIG. 1, the water stop ring 5 is a flat plate ring-shaped packing, and is made of a soft synthetic resin, rubber, or the like. The water stop ring 5 is formed with an insertion hole 50 through which the tubular portion 20 can be inserted.

図3及び図4に示すように、フランジ部材3、中間リング4及び止水リング5が挿入された筒状部20は、第一面101側から貫通孔103に挿入されている。 As shown in FIGS. 3 and 4, the tubular portion 20 into which the flange member 3, the intermediate ring 4, and the water stop ring 5 are inserted is inserted into the through hole 103 from the first surface 101 side.

図3及び図4に示すように、第二面102から突出した筒状部20の先端には、止水リング10、滑りリング6及び固定リング7が同順に取り付けられている。 As shown in FIGS. 3 and 4, a water blocking ring 10, a sliding ring 6, and a fixing ring 7 are attached to the tip of the tubular portion 20 protruding from the second surface 102 in the same order.

図1に示すように、止水リング10は、止水リング5と同様、平板リング状のパッキンである。止水リング10には、筒状部20が挿通可能な挿通孔11が形成されている。 As shown in FIG. 1, the water stop ring 10 is a flat plate ring-shaped packing like the water stop ring 5. The water stop ring 10 is formed with an insertion hole 11 through which the tubular portion 20 can be inserted.

図3及び図4に示すように、滑りリング6は、止水リング5と固定リング7との回動摩擦抵抗を低減させるためのリング状の部材である。図1に示すように、滑りリング6には、筒状部20が挿通可能な挿通孔60が形成されている。 As shown in FIGS. 3 and 4, the sliding ring 6 is a ring-shaped member for reducing the rotational frictional resistance between the water blocking ring 5 and the fixing ring 7. As shown in FIG. 1, the sliding ring 6 is formed with an insertion hole 60 through which the tubular portion 20 can be inserted.

図1に示すように、固定リング7の内周面には、筒状部20の雄ねじ部22に螺合する雌ねじ部70が形成されている。図1及び図2に示すように、固定リング7には、ビス8を挿通するためのビス孔71が、周方向に等間隔で複数(本実施形態では4箇所)が貫通形成されているとともに、工具を嵌めるための工具孔72が、周方向に等間隔で複数(本実施形態では2箇所)が形成されている。 As shown in FIG. 1, a female threaded portion 70 screwed into the male threaded portion 22 of the tubular portion 20 is formed on the inner peripheral surface of the fixing ring 7. As shown in FIGS. 1 and 2, a plurality of screw holes 71 for inserting the screws 8 are formed through the fixing ring 7 at equal intervals in the circumferential direction (four locations in the present embodiment). , A plurality of tool holes 72 for fitting tools (two in the present embodiment) are formed at equal intervals in the circumferential direction.

固定リング7を筒状部20の雄ねじ部22にねじ込む際には、工具孔72に水栓レンチ等の工具を差し込んで回転させることにより、固定リング7とフランジ部材3との間で壁体100を強く挟持できる。 When screwing the fixing ring 7 into the male threaded portion 22 of the tubular portion 20, a tool such as a faucet wrench is inserted into the tool hole 72 and rotated to rotate the wall body 100 between the fixing ring 7 and the flange member 3. Can be strongly pinched.

このように固定リング7を取り付けた状態で、筒状部20の先端が固定リング7より突出し過ぎている場合は、フランジ部材3の筒状部20に対するねじ込み量を調節し、筒状部20における固定リング7からの突出量を調節する。 When the tip of the tubular portion 20 protrudes too much from the fixing ring 7 with the fixing ring 7 attached in this way, the amount of screwing of the flange member 3 into the tubular portion 20 is adjusted to form the tubular portion 20. The amount of protrusion from the fixing ring 7 is adjusted.

図2〜図4に示すように、2本のビス8を固定リング7のビス孔71に挿通し、インパクトドライバー等の工具を使ってねじ込む。ビス8は、ドリル付タッピングビスであり、壁体100等に対して下穴無しでビス8をねじ込むことができる。 As shown in FIGS. 2 to 4, two screws 8 are inserted into the screw holes 71 of the fixing ring 7 and screwed in using a tool such as an impact wrench. The screw 8 is a tapping screw with a drill, and the screw 8 can be screwed into the wall body 100 or the like without a pilot hole.

ビス8は、固定リング7の挿通孔71に挿通され、滑りリング6及び止水リング10を貫通して壁体100へと螺入される。ビス8は、壁体100及び止水リング5を貫通して、中間リング4まで到達され、さらに中間リング4を貫通してフランジ部材3を貫通されている。 The screw 8 is inserted into the insertion hole 71 of the fixing ring 7, penetrates the sliding ring 6 and the water blocking ring 10, and is screwed into the wall body 100. The screw 8 penetrates the wall body 100 and the water stop ring 5 to reach the intermediate ring 4, further penetrates the intermediate ring 4, and penetrates the flange member 3.

ビス8は、固定リング7と壁体100とを相対回動不能とするとともに、中間リング4に係合されて、中間リング4と壁体100とを相対回動不能とする。 The screw 8 makes the fixing ring 7 and the wall body 100 relatively non-rotatable, and is engaged with the intermediate ring 4 to make the intermediate ring 4 and the wall body 100 relatively non-rotatable.

なお、図2に示すように、ビス8を、ビス孔71の4箇所のうち、エルボ部材9を傷つけないような箇所にねじ込む。つまり、固定リング7を筒状部20にねじ込む際は、継手本体2を避ける位置にビス孔71が配置されるように、固定リング7を調節する。 As shown in FIG. 2, the screw 8 is screwed into the four positions of the screw holes 71 so as not to damage the elbow member 9. That is, when the fixing ring 7 is screwed into the tubular portion 20, the fixing ring 7 is adjusted so that the screw hole 71 is arranged at a position avoiding the joint body 2.

ビス孔71が円周上に等間隔に4箇所形成されていることで、ビス孔71の位置調節は90°間隔で行うことができる。また、筒状部20に形成された平面部22を目安に、ビス孔71を平面部22の近傍に配置すると、エルボ部材9を傷つけない位置になる。 Since the screw holes 71 are formed at four positions on the circumference at equal intervals, the positions of the screw holes 71 can be adjusted at 90 ° intervals. Further, if the screw hole 71 is arranged in the vicinity of the flat surface portion 22 with the flat surface portion 22 formed in the tubular portion 20 as a guide, the elbow member 9 is not damaged.

さて、図2〜図4に示すように、管継手1を壁体100に取り付けた状態で、継手本体2の雌ねじ部23に対して水栓等をねじ込むと、継手本体2は水栓等に連れ回りしようとする。すると、継手本体2に形成された平面部24と、中間リング4に形成された板部41とが当たり、中間リング4も連れ回りしようとする。 By the way, as shown in FIGS. 2 to 4, when the faucet or the like is screwed into the female thread portion 23 of the joint body 2 with the pipe joint 1 attached to the wall body 100, the joint body 2 becomes a faucet or the like. Try to take him around. Then, the flat surface portion 24 formed on the joint body 2 and the plate portion 41 formed on the intermediate ring 4 come into contact with each other, and the intermediate ring 4 also tries to rotate.

しかし、中間リング4は、ビス8を介して壁体100に相対回動不能となっている。つまり、継手本体2を工具等で回り止めしておかなくとも、固定リング7用のビス8を利用して継手本体2の連れ回りを防止しており、水栓等を容易にねじ込むことができる。このように、固定リング7用のビス8を利用することで、構成の簡素化を図り得る。 However, the intermediate ring 4 cannot rotate relative to the wall body 100 via the screw 8. That is, even if the joint body 2 is not stopped by a tool or the like, the screw 8 for the fixing ring 7 is used to prevent the joint body 2 from rotating, and the faucet or the like can be easily screwed in. .. In this way, by using the screw 8 for the fixing ring 7, the configuration can be simplified.

また、図2、図3及び図4に示すように、管継手1において、中間リング4の外径は、固定リング7の外径より大きい。 Further, as shown in FIGS. 2, 3 and 4, in the pipe joint 1, the outer diameter of the intermediate ring 4 is larger than the outer diameter of the fixing ring 7.

作業者は、ビス8を固定リング7から中間リング4までねじ込む際、エルボ部材9を傷つけることを恐れ、固定リング7の径方向外側にねじ込んでしまう可能性がある。しかし、ビス8が固定リング7の径方向外側に傾いても、中間リング4にビス8を係合することができ、ビス8のねじ込み作業を容易にしている。 When screwing the screw 8 from the fixing ring 7 to the intermediate ring 4, the operator may damage the elbow member 9 and screw the screw 8 radially outward of the fixing ring 7. However, even if the screw 8 is tilted outward in the radial direction of the fixing ring 7, the screw 8 can be engaged with the intermediate ring 4, facilitating the screwing operation of the screw 8.
