Description

本発明は、排水システム等に適用可能な受け口部材及び継手に関する。   The present invention relates to a socket member and a joint applicable to a drainage system or the like.

近年、集合住宅等の多層建築物では、各階の衛生機器等から排出される排水は、各階の衛生機器等から横枝管を介してパイプシャフト内に設けられた排水立管路に集められ、曲管路や横管路を介して下水路に排水されるようになっている。このように各階の衛生機器等から排出される排水を下水道に排水するための排水システム(以下、単に排水システムという)では、排水立管路を構成する立管と横枝管とを接続するために、上端部及び下端部のそれぞれに立管を接続可能な本管と、該本管の側面に連結され、横枝管を接続可能な分岐管とを有する集合継手(継手)が用いられている。   In recent years, in multi-story buildings such as multi-family dwellings, drainage drained from sanitary equipment on each floor is collected from drainage equipment on each floor into drainage vertical pipes provided in pipe shafts via horizontal branch pipes, The water is drained to the lower water channel through the curved pipeline and the horizontal pipeline. Thus, in the drainage system (hereinafter simply referred to as drainage system) for draining the drainage drained from the sanitary equipment etc. of each floor to the sewer, in order to connect the vertical pipe and the horizontal branch pipe that constitute the drainage vertical pipe. A collective joint (joint) having a main pipe capable of connecting an upright pipe to each of the upper end and the lower end, and a branch pipe connected to a side surface of the main pipe and capable of connecting a horizontal branch pipe is used. There is.

集合継手の内部には、流入した排水を適度に旋回させるための旋回羽根が設けられている(例えば、特許文献1,2参照)。   Inside the collective joint, there is provided a turning blade for appropriately turning the inflowing drainage (see, for example, Patent Documents 1 and 2).

近年、排水システムの施工を行う作業者の減少、技術低下や、排水システムを構成する各種管材の耐久性の確保の観点から、樹脂製の管材を用いること、即ち排水ステムの樹脂化が進められている。立管、横枝管をはじめ、集合継手や脚部継手を全て樹脂製とすることで、軽量で耐久性に優れた排水システムを構成することができる。   In recent years, from the viewpoint of decreasing the number of workers who construct drainage systems, lowering the technology, and securing the durability of various types of piping materials that make up drainage systems, using resin-made piping materials, that is, making the drainage stem resinified ing. By making all the joint pipes and leg joints, including the upright pipe and the horizontal branch pipe, made of resin, it is possible to construct a drainage system which is light in weight and excellent in durability.

ところが、上述の各種管材を樹脂製にすると、射出成形用の金型(以下、単に金型という場合がある)の形状及び構造が複雑になり、費用がかかる。建築物の構造や様々な制約条件等に合わせて、個々に形状やサイズの異なる管材を製造し、品揃えを多くすると、初期投資費用が増大してしまう。   However, if the above-mentioned various pipe materials are made of resin, the shape and structure of a mold for injection molding (hereinafter sometimes simply referred to as a mold) will be complicated and expensive. If the tube materials having different shapes and sizes are individually manufactured and the assortment is increased in accordance with the structure of the building, various constraints, etc., the initial investment cost will increase.

上述の事態を解決する一方法として、共通の集合継手や脚部継手を用い、これらの継手の受け口に、嵌入される管材のサイズや形状に合った開口を有する部材を介在させ、前述の開口に管材を嵌める方法がある。例えば、特許文献1には、集合継手を共通のものとし、集合継手の上部及び下部の受け口に接続される立管の口径に応じた変換部材(ブッシュと呼ばれる場合がある)を用いて口径を変換する方法が開示されている。   As a method of solving the above-mentioned situation, a common collective joint or leg joint is used, and a member having an opening conforming to the size and shape of the tube to be inserted is interposed in the socket of these joint, There is a way to fit the tube to the For example, in Patent Document 1, the collective joint is made common, and the bore diameter is changed using a conversion member (sometimes called a bush) corresponding to the bore diameter of a standing pipe connected to the upper and lower receptacles of the collective joint. A method of conversion is disclosed.

また、特許文献2には、脚部継手の上部の受け口にオーバーハング部を設けた脚部ベンドの構造について開示されている。   Further, Patent Document 2 discloses a structure of a leg bend in which an overhang portion is provided in a socket at an upper portion of a leg joint.

特許第5483937号公報Patent No. 548 3937 特許第4210503号公報Patent No. 4210503

しかしながら、例えば特許文献1や特許文献2に記載されているブッシュの外周部には、図7に示すように、継手2の上流側の受け口10Aに内嵌されたブッシュ(受け口部材)15の内嵌方向の先端側の端部には水平方向に平行する部分(即ち、オーバーハング部BK)があり、下流側から上流側(即ち、下層から上層)に洗浄ノズルを移動させながら管内を洗浄する際に、洗浄ノズルの先端がオーバーハング部に引っかかり、上流側に進行し難いという問題があった。このような問題が生じると、洗浄作業の効率が低下する虞がある。   However, as shown in FIG. 7, for example, in the outer peripheral portion of the bush described in Patent Document 1 and Patent Document 2, the inside of the bush (receiver member) 15 internally fitted in the receptacle 10A on the upstream side of the joint 2 There is a horizontally parallel portion (ie, overhang portion BK) at the end on the tip side in the fitting direction, and the inside of the pipe is cleaned while moving the cleaning nozzle from the downstream side to the upstream side (ie, from the lower layer to the upper layer) In this case, there is a problem that the tip of the cleaning nozzle is caught in the overhang portion and it is difficult to move to the upstream side. If such a problem occurs, the efficiency of the cleaning operation may be reduced.

本発明は、上述の事情を鑑みてなされたものであり、内部の洗浄時に先端側から挿入された洗浄ノズルの先端を円滑に基端側へと導くことが可能な受け口部材及び該受け口部材を備えた継手を提供する。   The present invention has been made in view of the above-mentioned circumstances, and it is possible to smoothly guide the distal end of the cleaning nozzle inserted from the distal end side to the proximal end side at the time of internal cleaning, and the receptacle member Provide a fitted fitting.

本発明に係る継手の受け口部材は、排水システムの継手の受け口に内嵌可能、且つ前記排水システムの管材を外嵌可能に構成された受け口部材であって、
前記受け口に内嵌される方向の先端側には、外周側から内周側に向けて先端側から基端側へ後退する案内面が形成されていることを特徴とする。
上述の受け口部材において、前記案内面は外周側から内周側に向けて先端側から基端側へ線形に後退するように形成されてもよい。
上述の受け口部材において、前記案内面は外周側から内周側に向けて先端側から基端側へ階段状に後退するように形成されてもよい。
上述の受け口部材において、前記案内面は外周側から内周側に向けて先端側から基端側へ湾曲しつつ後退するように形成されてもよい。
The socket member of the joint according to the present invention is a socket member that can be fitted inside the socket of the joint of the drainage system and that can be fitted with the pipe material of the drainage system,
A guide surface which recedes from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side is formed on the distal end side in the direction of being fitted into the receiving port.
In the above-described receptacle member, the guide surface may be formed so as to linearly recede from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side.
In the above-mentioned receptacle member, the guide surface may be formed so as to be retracted stepwise from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side.
In the above-mentioned receptacle member, the guide surface may be formed to be retreated while curving from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side.

上述の構成によれば、継手の受け口に向けて洗浄ノズルが挿入され、案内面に当接した際に、案内面の形状に応じて洗浄ノズルが外周側から内周側に向けて移動しつつ先端側から基端側に後退するように案内されるので、内部で引っかかることなく、基端側に向けて円滑に移動可能になる。   According to the above configuration, when the cleaning nozzle is inserted toward the socket of the joint and abuts on the guide surface, the cleaning nozzle moves from the outer peripheral side to the inner peripheral side according to the shape of the guide surface. Since it is guided to be retracted from the distal side to the proximal side, it can be smoothly moved to the proximal side without being caught internally.

上述の受け口部材において、前記案内面において前記軸芯に直交する方向に平行な平行部分の前記直交する方向における幅は10mm以下であることが好ましい。   In the above-mentioned receptacle member, it is preferable that the width in the perpendicular direction of the parallel portion parallel to the direction perpendicular to the axial center in the guide surface is 10 mm or less.

上述の構成によれば、案内面に平行部分があったとしても平行部分の幅が10mm以内に抑えられているので、洗浄ノズルが平行部分に留まり難く、基端側に向けて円滑に移動可能になる。   According to the above configuration, the width of the parallel portion is suppressed within 10 mm even if there is a parallel portion in the guide surface, so the cleaning nozzle is difficult to stay in the parallel portion and can be smoothly moved toward the proximal end become.

上述の受け口部材において、前記案内面は周方向に沿って互いに間隔をあけて設けられた複数のリブの先端側の面で構成されていてもよい。
上述の受け口部材では、周方向における前記リブ同士の最大間隔は20mm以下であることが好ましい。
In the above-mentioned receptacle member, the guide surface may be constituted by a tip side surface of a plurality of ribs provided at intervals along the circumferential direction.
In the above-mentioned receptacle member, it is preferable that the maximum interval between the ribs in the circumferential direction is 20 mm or less.

上述の構成によれば、継手の受け口に向けて洗浄ノズルが挿入され、リブに当接した際に、リブの先端側の面の形状に応じて洗浄ノズルが外周側から内周側に向けて移動しつつ先端側から基端側に後退するように案内されるので、基端側に向けて円滑に移動可能になる。また、周方向の全体に亘って案内面を設ける場合に比べて周方向におけるリブ同士の間が切り欠かれている分、受け口部材の軽量化が図られる。
周方向におけるリブ同士の最大間隔が20mm以下であることにより、洗浄ノズルが確実にリブ間に嵌らずに済む。
According to the configuration described above, when the cleaning nozzle is inserted toward the socket of the joint and abuts against the rib, the cleaning nozzle is directed from the outer peripheral side to the inner peripheral side according to the shape of the surface of the distal end of the rib Since it is guided so as to move backward from the distal end side to the proximal end side while moving, it becomes possible to move smoothly toward the proximal end side. Further, as compared with the case where the guide surface is provided over the entire circumferential direction, weight reduction of the receiving member can be achieved because the gaps between the ribs in the circumferential direction are notched.
When the maximum distance between the ribs in the circumferential direction is 20 mm or less, the cleaning nozzle does not reliably fit between the ribs.

本発明に係る継手は、上述の受け口部材が受け口に対して内嵌されていることを特徴とする。   The joint according to the present invention is characterized in that the above-mentioned receptacle member is internally fitted to the receptacle.

上述の構成によれば、継手の受け口に向けて洗浄ノズルが挿入され、案内面に当接した際に、案内面の形状に応じて洗浄ノズルが外周側から内周側に向けて移動しつつ先端側から基端側に後退するように案内されるので、内部で引っかかることなく、基端側に向けて円滑に移動可能になる。これにより、継手の管内の洗浄作業の効率が高まる。   According to the above configuration, when the cleaning nozzle is inserted toward the socket of the joint and abuts on the guide surface, the cleaning nozzle moves from the outer peripheral side to the inner peripheral side according to the shape of the guide surface. Since it is guided to be retracted from the distal side to the proximal side, it can be smoothly moved to the proximal side without being caught internally. This increases the efficiency of the cleaning operation in the pipe of the joint.

本発明に係る受け口部材及び継手によれば、内部の洗浄時に先端側から挿入された洗浄ノズルの先端を円滑に基端側へと導くことができる。   According to the socket member and the joint according to the present invention, it is possible to smoothly guide the tip of the cleaning nozzle inserted from the distal end side to the proximal end side when cleaning the inside.

A book branch pipe 3 is provided. The axial centers of the three branch pipes 3A, 3B, 3C are arranged on the same line along the left-right direction (that is, the lateral direction), and are orthogonal to the axial center of the main pipe 2. In the following, the branch pipes 3A, 3B, and 3C will be referred to as the branch pipe 3 unless it is particularly necessary to distinguish between them, and this description is also used for the related components.

集合継手1の本管2の下部には筒状の短管5が内嵌され、短管5の下部にはテーパー管6が外嵌されている。すなわち、集合継手1と短管5とテーパー管6によって、継手構造8が構成されている。   A cylindrical short pipe 5 is internally fitted to the lower part of the main pipe 2 of the collective joint 1, and a tapered pipe 6 is externally fitted to the lower part of the short pipe 5. That is, a joint structure 8 is configured by the collective joint 1, the short pipe 5, and the tapered pipe 6.

図1に示すように、継手構造8は、マンション等の多層階からなる建築物(図示略)の排水システムに用いられるものである。具体的には、継手構造8は、各階の衛生機器等から排出される排水を流下させるための横枝管7と、パイプシャフト内の排水立管路を構成し、横枝管7を流下した排水を排水システムの最下部へと流下させる立管9とを接続可能に構成されている。   As shown in FIG. 1, the joint structure 8 is used for the drainage system of the building (not shown) which consists of multilayer floors, such as a condominium. Specifically, the joint structure 8 comprises a horizontal branch pipe 7 for letting down drainage discharged from sanitary equipment or the like on each floor, and a drainage upright pipe in the pipe shaft, and flows down the horizontal branch pipe 7 It is configured to be connectable to a standpipe 9 that allows the drainage to flow down to the lowermost part of the drainage system.

集合継手1の本管2の上部には立管9(例えば、立管9A)の下部が嵌合し、テーパー管6の下部には別の立管9(例えば、立管9B)の上部が嵌合している。テーパー管6は、下方向に進むに従って縮径するように形成されている。テーパー管6の上端部の内径および外径は、短管5の外径等を勘案して適当に設定されている。また、テーパー管6の下端部の内径および外径は、立管9の外径等を勘案して適当に設定されている。   The lower part of vertical pipe 9 (for example, vertical pipe 9A) fits in the upper part of main pipe 2 of collective joint 1, and the upper part of another vertical pipe 9 (for example, vertical pipe 9B) It is fitting. The tapered tube 6 is formed to decrease in diameter as it proceeds downward. The inner diameter and the outer diameter of the upper end portion of the tapered tube 6 are appropriately set in consideration of the outer diameter of the short tube 5 and the like. Further, the inner diameter and the outer diameter of the lower end portion of the tapered tube 6 are appropriately set in consideration of the outer diameter of the upright tube 9 and the like.

集合継手1の分岐管3のそれぞれには、横枝管7の下流側の端部が嵌合している。   The downstream end of the horizontal branch pipe 7 is fitted to each of the branch pipes 3 of the collective joint 1.

継手構造8は、上下方向で隣り合う各階の間に介在するコンクリート製の床スラブSに形成された貫通孔Hに挿通されている。貫通孔Hの側壁と継手構造8との間は、モルタルMが充填されている。特に、分岐管3の下端より下方の集合継手1と短管5とテーパー管6の上部とは、モルタルM内に埋設されている。   The joint structure 8 is inserted through a through hole H formed in a floor slab S made of concrete between adjacent floors in the vertical direction. A mortar M is filled between the side wall of the through hole H and the joint structure 8. In particular, the collective joint 1 below the lower end of the branch pipe 3, the short pipe 5, and the upper portion of the tapered pipe 6 are embedded in the mortar M.

建築物の最下階の床スラブSBに挿通された継手構造8のテーパー管6の下端6bには、上流側から所定の位置で水平方向に向けて屈曲した脚部継手(継手)62が嵌合されている。脚部継手62の下流側の端部に横主管63が嵌合している。横主管63の下流側の端部(図示略)は、不図示の下水道に接続されている。   The lower end 6b of the tapered pipe 6 of the joint structure 8 inserted into the floor slab SB of the lowest floor of the building is fitted with a leg joint (joint) 62 bent horizontally at a predetermined position from the upstream side It is united. A horizontal main pipe 63 is fitted to the downstream end of the leg joint 62. The downstream end (not shown) of the horizontal main pipe 63 is connected to a sewer (not shown).

図2に示すように、本発明を適用した一実施形態の受け口部材20は、上述の排水システムにおける集合継手1や脚部継手62の受け口10に内嵌可能、且つ排水システムの立管(管材)9や横枝管(管材)7を外嵌可能に構成された筒状の部材であり、ブッシュと呼ばれる部材等である。即ち、受け口部材20は、径方向において集合継手1や脚部継手62の受け口10と立管9や横枝管7との間に介在する部材である。   As shown in FIG. 2, the socket member 20 of one embodiment to which the present invention is applied can be fitted internally to the socket 10 of the collective joint 1 or the leg joint 62 in the drainage system described above, and a standing pipe of the drainage system 9) and a horizontal branch pipe (pipe material) 7 can be externally fitted, and is a member called a bush or the like. That is, the socket member 20 is a member interposed between the socket 10 of the collective joint 1 or the leg joint 62 and the vertical pipe 9 or the horizontal branch pipe 7 in the radial direction.

受け口部材20Aは、集合継手1の本管2の上流側の受け口10Aに内嵌可能とされている。受け口部材20Aにおいて、受け口10Aに内嵌される方向(以下、I方向とする)の先端側には、外周側から内周側に向けて先端側から基端側へ後退する案内面30が形成されている。   The receptacle member 20A can be fitted inside the receptacle 10A on the upstream side of the main pipe 2 of the collective joint 1. In the receptacle member 20A, on the distal end side in the direction (hereinafter, referred to as I direction) internally fitted to the receptacle 10A, a guide surface 30 is formed which recedes from the distal end to the proximal end from the outer peripheral side to the inner peripheral side. It is done.

案内面30の第一の態様として、図2に示すように、外周側から内周側に向けて先端側から基端側へ線形に後退するように形成されている案内面30Aが挙げられる。受け口部材20の軸芯Jに沿った方向(以下、J方向とする)に直交する方向(即ち、径方向)に対する案内面30Aの傾斜角度は、30度以上60度以下であることが好ましく、45度程度であることがより好ましい。案内面30Aの傾斜角度が上述のように設定されることで、二点鎖線で示す洗浄ノズルNの先端Tが受け口部材20Aの先端側から基端側に向けて(即ち、集合継手1の下流側から上流側に向けて)挿入され、案内面30Aに当接した際に、より円滑に受け口部材20Aの基端側に案内される。   As a first aspect of the guide surface 30, as shown in FIG. 2, a guide surface 30A formed so as to linearly recede from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side can be mentioned. The inclination angle of the guide surface 30A with respect to the direction (that is, the radial direction) orthogonal to the direction (hereinafter referred to as the J direction) along the axis J of the receptacle member 20 is preferably 30 degrees or more and 60 degrees or less. More preferably, it is about 45 degrees. By setting the inclination angle of the guide surface 30A as described above, the tip T of the cleaning nozzle N indicated by the two-dot chain line is directed from the tip side to the base end of the receiving member 20A (ie, downstream of the collective joint 1) When it is inserted from the side toward the upstream side and abuts on the guide surface 30A, it is guided more smoothly to the proximal end side of the mouthpiece member 20A.

案内面30の第二の態様として、図3に示すように、外周側から内周側に向けて先端側から基端側へ階段状に後退するように形成されている案内面30Bが挙げられる。   As a second embodiment of the guide surface 30, as shown in FIG. 3, a guide surface 30B formed so as to be retracted stepwise from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side can be mentioned. .

また、案内面30の第三の態様として、図4に示すように、外周側から内周側に向けて先端側から基端側へ凸状に湾曲しつつ後退するように形成されている案内面30Cが挙げられる。なお、図示していないが、案内面30Cは、外周側から内周側に向けて先端側から基端側へ凹状に湾曲しつつ後退するように形成されていても構わない。   Further, as a third aspect of the guide surface 30, as shown in FIG. 4, a guide formed so as to be curved while being convexly curved from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side Face 30C is mentioned. Although not illustrated, the guide surface 30C may be formed so as to be recessed while being concavely curved from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side.

案内面30B,30Cにおいて、J方向に直交する方向(即ち、径方向)に平行な平行部分30pの径方向における幅wは0mm以上10mm以下であることが好ましい。なお、案内面30Cのように湾曲形状を有する面における平行部分30pとは、案内面30Cの接線が径方向に対してなす角度が例えば5度以内である部分をいう。平行部分30pの幅wが前述の範囲内であることにより、洗浄ノズルNの先端Tが平行部分30pに留まり難く、或いは引っかかり難く、基端側に向けて円滑に移動可能になる。   In the guide surfaces 30B and 30C, the width w in the radial direction of the parallel portion 30p parallel to the direction (that is, the radial direction) orthogonal to the J direction is preferably 0 mm or more and 10 mm or less. In addition, the parallel part 30p in the surface which has curved shape like 30 C of guide surfaces means the part which the angle which the tangent of 30 C of guide surfaces makes with respect to radial direction is less than 5 degree | times, for example. When the width w of the parallel portion 30p is within the above-described range, the tip T of the cleaning nozzle N is unlikely to stay at the parallel portion 30p or is not easily caught, and can move smoothly toward the proximal side.

図5に示すように、案内面30は周方向(図5に示すR方向)に沿って互いに間隔をあけて設けられた複数のリブ32の先端側の面34で構成されていてもよい。R方向におけるリブ32,32同士の最大間隔は0mm以上20mm以下であることが好ましく、0mm以上10mm以下であることがより好ましい。リブ32,32同士の最大間隔が20mmより大きくなると、洗浄ノズルNの先端Tがリブ32,32の間に嵌まる虞がある。   As shown in FIG. 5, the guide surface 30 may be configured by surfaces 34 on the tip end side of a plurality of ribs 32 provided spaced apart from each other along the circumferential direction (direction R shown in FIG. 5). The maximum distance between the ribs 32 and 32 in the R direction is preferably 0 mm or more and 20 mm or less, and more preferably 0 mm or more and 10 mm or less. If the maximum distance between the ribs 32, 32 is greater than 20 mm, the tip T of the cleaning nozzle N may fit between the ribs 32, 32.

なお、受け口部材20と立管9との間の止水性を高める目的で、径方向における受け口部材20と立管9との間には、ゴム部材18が配置されている。   A rubber member 18 is disposed between the receiving member 20 and the vertical pipe 9 in the radial direction for the purpose of enhancing the waterproofness between the receiving member 20 and the vertical pipe 9.

図6に示すように、受け口部材20Bは、排水システムの脚部継手62(図1等も参照)の上流側の受け口10Bに内嵌可能とされている。   As shown in FIG. 6, the receptacle member 20B can be fitted inside the receptacle 10B on the upstream side of the leg joint 62 (see also FIG. 1 etc.) of the drainage system.

受け口部材20Bにおいて、受け口10Bに内嵌されるI方向の先端側には、外周側から内周側に向けて先端側から基端側へ後退する案内面40が形成されている。なお、案内面40についても、案内面30における第一から第三の態様及び好適な条件を採用することができる。   In the receptacle member 20B, on the distal end side in the I direction which is internally fitted to the receptacle 10B, a guide surface 40 which recedes from the distal end side to the proximal end side from the outer peripheral side to the inner peripheral side is formed. In addition, also about the guide surface 40, the 1st to 3rd aspect and suitable conditions in the guide surface 30 are employable.

内部を流下する流体の旋回を良好に起こさせる観点から、受け口部材20Bは脚部継手62の上下方向に延びる部分に対して偏心している。従って、受け口部材20Bの径方向の内側の案内面40aの傾斜角度が径方向外側の案内面40bの傾斜角度より大きく設けられている。   The receptacle member 20B is eccentric with respect to the vertically extending portion of the leg joint 62 in order to favorably cause the fluid flowing down inside to swirl. Therefore, the inclination angle of the radially inner guide surface 40a of the receptacle member 20B is larger than the inclination angle of the radially outer guide surface 40b.

最下層の継手構造8では、床スラブSBの厚みに合わせて、受け口部材20Bに内嵌される管材を選択することができる。例えば、床スラブSBの厚みがかなり小さい場合は、短管5に替えて、集合継手1の本管2の下流側の受け口10Bを直接内嵌させることができる。また、床スラブSBの厚みがかなり大きい場合は、長めの短管5の一方の端部を内嵌させることができる。   In the joint structure 8 of the lowermost layer, it is possible to select a pipe material fitted in the receiving port member 20B in accordance with the thickness of the floor slab SB. For example, when the thickness of the floor slab SB is considerably small, it is possible to replace the short pipe 5 and directly fit the receptacle 10B on the downstream side of the main pipe 2 of the collective joint 1. Moreover, when the thickness of the floor slab SB is considerably large, one end of the longer short pipe 5 can be fitted inside.

以上説明した本実施形態の受け口部材20A,20B、集合継手1及び脚部継手62によれば、受け口部材20A,20Bの内径や中心の位置を変更することにより、共通の集合継手1及び脚部継手62に対して接続する管材の外径や中心位置を容易に変えることができる。即ち、少ない品揃えで、集合継手1及び脚部継手62に嵌める管材の口径等を変更することができる。また、集合継手1や脚部継手62ことができる。これにより、洗浄時に洗浄ノズルNの先端Tをスムーズに上流側(上層)に導き、管内の洗浄作業を円滑に進めることができる。   According to the socket members 20A and 20B, the collective joint 1 and the leg joint 62 of the present embodiment described above, the common collective joint 1 and the leg portion are common by changing the inner diameter and the center position of the socket members 20A and 20B. The outer diameter and center position of the pipe material connected to the joint 62 can be easily changed. That is, the bore diameter and the like of the pipe material fitted to the collective joint 1 and the leg joint 62 can be changed with a small assortment. Also, the joint assembly 1 and the leg joint 62 can be used. Thus, the tip T of the cleaning nozzle N can be smoothly guided to the upstream side (upper layer) at the time of cleaning, and the cleaning operation in the pipe can be smoothly advanced.

また、本実施形態の受け口部材20A,20B、集合継手1及び脚部継手62によれば、案内面30において平行部分30pの径方向(J方向に直交する方向)における幅は10mm以下であるので、案内面30に平行部分30pを設けても、洗浄ノズルNの先端Tを平行部分30pによって留めることなく、基端側に向けて円滑に移動させることができる。   Further, according to the socket members 20A and 20B, the collective joint 1 and the leg joint 62 of the present embodiment, the width of the parallel portion 30p in the radial direction (direction orthogonal to the J direction) in the guide surface 30 is 10 mm or less Even if the guide surface 30 is provided with the parallel portion 30p, the distal end T of the cleaning nozzle N can be smoothly moved toward the proximal end without being held by the parallel portion 30p.

また、本実施形態の受け口部材20A,20B、集合継手1及び脚部継手62によれば、案内面30は複数のリブ32の先端側の面34で構成されているので、リブ32の面34によって洗浄ノズルNの先端Tを円滑に移動させつつ、リブ32を設けない場合に比べて受け口部材20A,20Bの軽量化を図ることができる。特に、リブ32同士の最大間隔は20mm以下であることによって、リブ32同士の間に洗浄ノズルNの先端Tが嵌らないようにすることができる。   Further, according to the socket members 20A, 20B, the collective joint 1 and the leg joint 62 of the present embodiment, the guide surface 30 is constituted by the surface 34 of the distal end side of the plurality of ribs 32. Thus, while the tip end T of the cleaning nozzle N is smoothly moved, the weight reduction of the receptacle members 20A and 20B can be achieved as compared with the case where the rib 32 is not provided. In particular, by setting the maximum distance between the ribs 32 to 20 mm or less, the tip T of the cleaning nozzle N can be prevented from fitting between the ribs 32.
