Description

本発明は、浴室内に洗面器を設置した浴室ユニットに係り、特に洗面器から排水するための洗面排水装置に関する。   The present invention relates to a bathroom unit in which a wash basin is installed in a bathroom, and more particularly to a wash drainage device for draining water from a wash basin.

比較的狭い集合住宅やホテル客室等の浴室ユニットとして、浴室内に水栓を伴った洗面器を備えるタイプが採用されることが多い。   As a bathroom unit of a relatively small apartment house or hotel guest room, a type having a washbasin with a faucet in the bathroom is often adopted.

この洗面器で使用された水を排水する方法として、浴室内に設置された浴槽とこの浴槽に設けられたエプロンとの間に上端の連結管部をエプロンに固着してエプロン表面に開口させた排水管を配置し、浴槽に隣接して設置された洗面器に接続した洗面排水管を上記連結管部に接続して成る浴室用洗面排水装置を設けるものがある(例えば、特許文献1参照。)。   As a method of draining the water used in this basin, the upper end connecting pipe part was fixed to the apron between the bathtub installed in the bathroom and the apron provided in the bathtub, and was opened on the apron surface. Some have a bathroom drainage device in which a drainage pipe is arranged and a bathroom drainage pipe connected to a washbasin installed adjacent to a bathtub is connected to the connecting pipe part (see, for example, Patent Document 1). ).

この浴室用洗面排水装置を、洗い場の床と浴槽とをエプロンを介して一体に形成するハーフ構造に適用した例を、図10に示す。排水トラップに連接される連結管部の上端(エルボ101)は、接着剤を用いてエプロン102裏面に、工場において先行接続される。また、洗面排水管103も、接着剤を用いてエルボ101に、工場において先行接続される。したがって、この接続部分からの漏水は殆ど考えられない。ハーフ構造では、エプロンを取り外すことができないので、エルボ101から洗面排水管103を取り外すこともないことから可能となる接続方法である。   An example in which this bathroom drainage device is applied to a half structure in which a floor and a bathtub of a washing place are integrally formed through an apron is shown in FIG. The upper end (elbow 101) of the connecting pipe portion connected to the drain trap is connected in advance at the factory to the back surface of the apron 102 using an adhesive. In addition, the flush drainage pipe 103 is also connected in advance to the elbow 101 at the factory using an adhesive. Therefore, the water leakage from this connection part is hardly considered. In the half structure, since the apron cannot be removed, the wash drainage pipe 103 is not removed from the elbow 101, which is a connection method that is possible.

他方、床全面に敷設された防水パン上に浴槽を載置するフルパン構造の浴室用洗面排水装置としては、排水口に下端を挿入する第1排水管をエプロン面裏面に設け、該エプロン面に開孔した連結孔に上記第1排水管の上端を臨ませ、その第1排水管内面にシール材を介して、一端を洗面器の排水金具に接続する第2排水管の他端を嵌合してなるものがある(例えば、特許文献2参照。)。   On the other hand, as a bathroom flush drainage device with a full pan structure on which a bathtub is placed on a waterproof pan laid on the entire floor, a first drain pipe for inserting a lower end into a drain outlet is provided on the back of the apron surface, The upper end of the first drain pipe faces the opened connection hole, and the other end of the second drain pipe that connects one end to the drainage fitting of the basin is fitted on the inner surface of the first drain pipe via a sealing material (For example, refer to Patent Document 2).

この浴室用洗面排水装置では、浴槽周り点検等のためにエプロンを取り外す必要があるので、第2排水管(洗面排水管)はゴムパッキン等のシール材を介して第1排水管内に挿入されるだけで、接着固定はされない。よって、何度でも取り外し可能であるが、再度取り付ける際、場合によっては、ゴムパッキンと第2排水管との接触がうまくいかず、そこから漏水する虞がある。尤も、フルパン構造では浴槽下にも防水パンが敷設されているので、室外へ漏水することはない。   In this bathroom drainage device, since it is necessary to remove the apron for inspection around the bathtub, the second drainage pipe (wash drainage pipe) is inserted into the first drainage pipe through a sealing material such as rubber packing. Only adhesive fixing is not done. Therefore, although it can be removed any number of times, when it is reattached, in some cases, the contact between the rubber packing and the second drain pipe is not good, and there is a risk of water leaking from there. However, since the waterproof pan is laid under the bathtub in the full pan structure, water does not leak outside.

ところで、ハーフ構造には、ハーフ分割構造と呼ばれるバリエーションがある。これは、浴槽を、防水パンを介することなく建築床の上に載置する点で、本来のハーフ構造と共通するものの、浴槽と洗い場床とは別体で成形され、据付現場において連結される点で相違する。このハーフ分割構造では、浴槽の洗い場に面する側面は、洗い場床及び浴槽が所定の位置に設置された後、別体のエプロンによって掩蔽される。   By the way, the half structure has a variation called a half divided structure. This is the same as the original half structure in that the bathtub is placed on the building floor without going through a waterproof pan, but the bathtub and the washing floor are molded separately and connected at the installation site. It is different in point. In this half-divided structure, the side of the bathtub facing the washing area is covered with a separate apron after the washing floor and the bathtub are installed at predetermined positions.

ある程度以上の大きさのユニットバスでは、洗い場床と浴槽とを一体で形成することが難しいのみならず、現場への搬入や据付時の取り回しが困難になる。ハーフ分割構造は、この問題を解決すべく、洗い場床と浴槽とを別体で成形することにしたものである。   In a unit bath of a certain size or more, it is difficult not only to integrally form the washing floor and the bathtub, but also it is difficult to carry it into the site and to handle it during installation. In order to solve this problem, the half divided structure is formed by separately forming the washing floor and the bathtub.

ところが、ハーフ分割構造では、追焚工事や点検等のためにエプロンを取り外す必要があるため、洗面排水管を、エプロンに固着されたエルボに接着剤を用いて接続することはできない。そこで、フルパン構造のように、洗面排水管を、ゴムパッキン等のシール材を介して第1排水管内に挿入する浴室用洗面排水装置を採用すると、洗面排水管を何度も取り外すうちに、ゴムパッキンと洗面排水管との接触がうまくいかず、そこから漏水する可能性がある。その場合、ハーフ分割構造では浴槽下に防水パンが敷設されていないので、室外へ漏水する虞が生じる。   However, in the half-divided structure, since it is necessary to remove the apron for memorial work or inspection, the wash drainage pipe cannot be connected to the elbow fixed to the apron using an adhesive. Therefore, if a bathroom drainage device is used that inserts the wash drainage pipe into the first drain pipe through a sealing material such as rubber packing as in the full pan structure, the rubber drainage pipe is removed while the wash drainage pipe is removed many times. There is a possibility that the contact between the packing and the drainage pipe will not be successful, and water may leak from there. In that case, since the waterproof pan is not laid under the bathtub in the half-divided structure, there is a risk of water leaking outside the room.

このように、洗面器の排水構造について止水性に不安があるので、ハーフ分割構造では、洗面器付きのものは今まで採用されていない。   Thus, since there is anxiety about a water stop about the drainage structure of a basin, the thing with a basin has not been adopted by the half division structure until now.

ところで、浴室をリフォームするに際しては、周囲に既存の壁等の障害物が存在することが多い。特にマンション等の集合住宅においては、たとえ小型の浴室であっても(新設時にはハーフ構造の浴室であっても)、現場への搬入や据付時の取り回しを考慮すると、洗い場床と浴槽とを分割したハーフ分割構造を採用した方が、既存の間仕切壁等を壊さなくても設置ができるので、都合がよいという現状がある。   By the way, when remodeling a bathroom, there are many obstacles such as existing walls around. Especially in apartment houses such as condominiums, even if it is a small bathroom (even if it is a half-structured bathroom when newly constructed), considering the handling at the time of installation and installation, the washing floor and bathtub are separated The half-divided structure is convenient because it can be installed without breaking existing partition walls.

本発明に係る浴室ユニットの洗面排水装置の実施の形態について、添付図面を参照して説明する。図1は、本実施形体に係る洗面排水装置11を備える浴室ユニット1の全体的な概要を示す立面図である。   An embodiment of a bathroom drainage device for a bathroom unit according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is an elevation view showing an overall outline of a bathroom unit 1 including a toilet drainage device 11 according to the present embodiment.

浴室ユニット1は、FRP等で成形された洗い場床2と、この洗い場床2とは別体に成形された浴槽3とを備え、これらは、それぞれ独立して建築床F上に支持脚2a,3aを介して設置された後、図示しない分割床連結材によって連結され、相互の位置関係が固定される。そして、浴槽3の洗い場床2に面する側面は、別体に形成されたエプロン4によって掩蔽される。   The bathroom unit 1 includes a wash floor 2 formed of FRP or the like, and a bathtub 3 formed separately from the wash floor 2, which are independently supported on the building floor F by supporting legs 2a, After installing through 3a, it connects with the division | segmentation floor connection material which is not shown in figure, and mutual positional relationship is fixed. And the side surface which faces the washing-room floor 2 of the bathtub 3 is obscured by the apron 4 formed separately.

洗い場床2の水下には、下面に排水トラップ5が取設され、洗い場床2からの排水が集水されるとともに、浴槽3からの排水も排水エルボ6を介して集水され、これらの排水は、浴室ユニット1外部へと排出される。   Under the water of the washing floor 2, a drain trap 5 is installed on the lower surface. The drainage from the washing floor 2 is collected, and the drainage from the bathtub 3 is also collected through the drainage elbow 6. The drainage is discharged to the outside of the bathroom unit 1.

浴室ユニットの壁面を構成する壁パネル7は、洗い場床2周りではその外縁上に立設され、浴槽3周りでは浴槽3のリム3b上に立設される。   The wall panel 7 constituting the wall surface of the bathroom unit is erected on the outer edge around the washing floor 2, and is erected on the rim 3 b of the bathtub 3 around the bathtub 3.

洗い場床2上の浴槽3近傍の壁パネル7には、洗面器8が、その斜め上方には水栓9が取り付けられる。水栓9は、混合栓タイプであり、カランを回動させることにより、浴槽3及び洗面器8に給水・給湯可能であり、また、吐水先を切り替えることによりシャワー10にも給水・給湯することができる。   A washbasin 8 is attached to the wall panel 7 in the vicinity of the bathtub 3 on the washing floor 2, and a faucet 9 is attached obliquely above. The faucet 9 is of a mixing faucet type, and can rotate the currant to supply water / hot water to the bathtub 3 and the basin 8, and also supply water / hot water to the shower 10 by switching the water discharge destination. Can do.

洗面器7下部には、洗面器側排水管12が接続され、洗面器側排水管12の他端は、エプロン4近傍において、浴槽側排水管20に連接される。洗面器側排水管12と浴槽側排水管20との連接部分は、ワン座によって掩蔽される。浴槽側排水管20は、エプロン4裏面を下降して、他端は排水エルボ6と合流し、最終的には排水トラップ5に接続される。   A basin side drain pipe 12 is connected to the lower part of the basin 7, and the other end of the basin side drain pipe 12 is connected to the bathtub side drain pipe 20 in the vicinity of the apron 4. The connecting portion between the basin-side drain pipe 12 and the bathtub-side drain pipe 20 is covered with a single seat. The bathtub-side drain pipe 20 descends the back surface of the apron 4 and the other end joins the drain elbow 6 and is finally connected to the drain trap 5.

これにより、洗面器8で使用された水は、洗面器側排水管12、浴槽側排水管20及び排水トラップ5を経由して外部に排水される。   Thereby, the water used in the basin 8 is drained to the outside through the basin side drain pipe 12, the bathtub side drain pipe 20 and the drain trap 5.

図1に示したA周りの詳細を図2に示す。浴槽側排水管20は 浴槽側排水管20の本管21の先端近傍に取設されたエルボ22によって折曲され、その先端にソケット23が連接される。   Details around A shown in FIG. 1 are shown in FIG. The bathtub-side drain pipe 20 is bent by an elbow 22 installed near the tip of the main pipe 21 of the bathtub-side drain pipe 20, and a socket 23 is connected to the tip.

ソケット23は、図示しない分割床連結材に取設された洗面器排水支持材42に取着される。これにより、浴槽側排水管20の上端位置が固定される。   The socket 23 is attached to a basin drainage support material 42 installed on a divided floor connecting material (not shown). Thereby, the upper end position of the bathtub side drain pipe 20 is fixed.

ソケット23は、円筒状の筒状部23aと、この筒状部23a中央付近から外方へ延出する鍔部23bとを有する。また、筒状部23a先端には雄ねじ部23cが螺刻される。   The socket 23 has a cylindrical tubular portion 23a and a flange portion 23b extending outward from the vicinity of the center of the tubular portion 23a. A male screw portion 23c is threaded at the tip of the cylindrical portion 23a.

エプロン4は、その上端が浴槽3のリム3b裏面と補強用リブ3cとの間にパッキン43,44を介して挟装され、図示しない下端は、洗い場床2の浴槽3側縁部に立ち上げられた土手部に載置されることによって、浴槽3と洗い場床2との間に架設される。   The apron 4 has an upper end sandwiched between the back surface of the rim 3b of the bathtub 3 and the reinforcing rib 3c via packings 43 and 44, and a lower end (not shown) is raised at the edge of the washing floor 2 on the side of the bathtub 3 It is constructed between the bathtub 3 and the washing floor 2 by being placed on the bank.

エプロン4には、貫通孔THが設けられ、エプロン4が所定の位置に立設されると、この貫通孔THに、浴槽側排水管20先端のソケット23が挿通されるようになっている。   The apron 4 is provided with a through hole TH, and when the apron 4 is erected at a predetermined position, the socket 23 at the tip of the bathtub-side drain pipe 20 is inserted into the through hole TH.

この貫通孔THには、開口全周に亘ってシール部材30が取着される。シール部材30は、貫通パッキン31と、軟質部材32と、滑り部材33との3層より構成される。   The seal member 30 is attached to the through hole TH over the entire circumference of the opening. The seal member 30 includes three layers of a through packing 31, a soft member 32, and a sliding member 33.

貫通パッキン31は、洗い場の水が開口周りからエプロン4裏面に廻ることを防止するものであり、ゴム等により形成され、取付部31a及び弾性部31bから成る。   The through-packing 31 prevents the water in the washing area from flowing from the periphery of the opening to the back surface of the apron 4, is formed of rubber or the like, and includes an attachment portion 31a and an elastic portion 31b.

取付部31aは、貫通孔TH周りのエプロン4を表裏から挟持して、シール部材30を貫通孔TH周りに水密に取着する。弾性部31bは、この取付部31aから貫通孔THの径方向内方側に向けて全周に亘って突出する弾性変形可能な部材である。   The attachment portion 31a sandwiches the apron 4 around the through hole TH from the front and back, and attaches the seal member 30 around the through hole TH in a watertight manner. The elastic part 31b is an elastically deformable member that protrudes over the entire circumference from the attachment part 31a toward the radially inner side of the through hole TH.

弾性部31bは、貫通孔THにソケット23が挿通する以前は、中央が円形に開口した平円盤であり、その厚さは、折曲し易いように、1〜4mm程度の薄肉である。この開口OPの半径は、ソケット23の筒状部23aの外径より小さいので、貫通孔THにソケット23が挿通されると、ソケット23の先端に押されて開口OPが拡開するとともに、図2に示すように、弾性部31bの先端部分が折曲変形して、弾性部31bの側面がソケット23の筒状部23aに水密に当接する。これにより、洗い場側の水が、ソケット23外周とエプロン4の貫通孔THとの間からエプロン4裏面側へ漏出することが防止される。   The elastic part 31b is a flat disk having a circular opening at the center before the socket 23 is inserted into the through-hole TH, and the thickness thereof is about 1 to 4 mm so as to be easily bent. Since the radius of the opening OP is smaller than the outer diameter of the cylindrical portion 23a of the socket 23, when the socket 23 is inserted through the through hole TH, the opening OP is expanded by being pushed by the tip of the socket 23. As shown in FIG. 2, the distal end portion of the elastic portion 31 b is bent and deformed, and the side surface of the elastic portion 31 b comes into contact with the cylindrical portion 23 a of the socket 23 in a watertight manner. Thereby, the water on the washing place side is prevented from leaking from between the outer periphery of the socket 23 and the through hole TH of the apron 4 to the back side of the apron 4.

軟質部材32は、外径及び内径が貫通パッキン31の取付部31aのそれと略同一の短い円筒状であり、取付部31aの表面側(洗い場側)に貼着される。軟質部材32は、柔軟な合成樹脂等により形成されているので、側方からの押圧により容易に圧縮変形する。   The soft member 32 has a short cylindrical shape whose outer diameter and inner diameter are substantially the same as those of the attachment portion 31a of the through packing 31, and is attached to the surface side (washing area side) of the attachment portion 31a. Since the soft member 32 is formed of a flexible synthetic resin or the like, it is easily compressed and deformed by pressing from the side.

滑り部材33は、軟質部材32の、貫通パッキン31の取付部31aとは反対側の側面に貼着された、外径及び内径が軟質部材32のそれと略同一の薄い円盤状の部材であり、例えば合成樹脂より成る。   The sliding member 33 is a thin disk-like member that is attached to the side surface of the soft member 32 opposite to the attachment portion 31a of the through-packing 31 and has an outer diameter and an inner diameter that are substantially the same as those of the soft member 32. For example, it consists of a synthetic resin.

後述する締付フランジ24は、ソケット23の雄ねじ部23cと螺合して、シール部材30を押圧する。ここで、シール部材30表面の摩擦抵抗が、軟質部材32のそれのように大きいと 回転する締付フランジ24に引っ張られて、表面がねじ切れる虞がある。そこで、摩擦抵抗の小さい滑り部材33を軟質部材32表面に貼着することにより、締付フランジ24が回転しても、それに引っ張られないようにしたものである。   A tightening flange 24 to be described later is screwed into the male screw portion 23 c of the socket 23 to press the seal member 30. Here, if the frictional resistance of the surface of the seal member 30 is as large as that of the soft member 32, the surface may be twisted by being pulled by the rotating fastening flange 24. Therefore, the sliding member 33 having a small frictional resistance is adhered to the surface of the soft member 32 so that the tightening flange 24 is not pulled even if it rotates.

締付フランジ24は、ソケット23の雄ねじ部23cと螺合する雌ねじ部24aと、この雌ねじ部24aの一端から径方向外方へ延出するフランジ部24bとを有する。また、フランジ部24b背面からは、図3に示すように、放射状に複数の凸条24cが設けられている。   The tightening flange 24 includes a female screw portion 24a that is screwed with the male screw portion 23c of the socket 23, and a flange portion 24b that extends radially outward from one end of the female screw portion 24a. Further, as shown in FIG. 3, a plurality of ridges 24c are provided radially from the back surface of the flange portion 24b.

締付フランジ24の雌ねじ部24a先端と、ソケット23の雄ねじ部23c先端とを位置合わせした後、凸条24cを手で持って捩れば、締付フランジ24を容易にソケット23方向へ螺進させることができる。   After aligning the tip of the female threaded portion 24a of the tightening flange 24 and the tip of the male threaded portion 23c of the socket 23, if the ridge 24c is held and twisted by hand, the tightening flange 24 is easily screwed toward the socket 23. be able to.

締付フランジ24の雌ねじ部24a終端がソケット23の雄ねじ部23c先端まで至ると、両者の螺合が完了する。この状態で、シール部材30のエプロン4裏面側の取付部31aは、ソケット23の鍔部23bと水密に当接し、シール部材30の滑り部材33は締付フランジ24のフランジ部24b表面と水密に当接する。これにより、洗い場側の水が、ソケット23外周とエプロン4の貫通孔THとの間からエプロン4裏面側へ漏出することが、より確実に防止される。   When the terminal end of the female screw portion 24a of the tightening flange 24 reaches the tip of the male screw portion 23c of the socket 23, the screwing of both ends is completed. In this state, the attachment portion 31a on the back side of the apron 4 of the seal member 30 is in watertight contact with the flange portion 23b of the socket 23, and the sliding member 33 of the seal member 30 is watertight with the surface of the flange portion 24b of the tightening flange 24. Abut. Thereby, it is more reliably prevented that the water on the washing station side leaks from between the outer periphery of the socket 23 and the through hole TH of the apron 4 to the back side of the apron 4.

ゴムブッシュ13は、ソケット23先端に挿入され、ソケット23内周と洗面器側排水管12外周との間隙を水密に閉塞する。ゴムブッシュ13は、円筒状の筒状部13aと、その一端から径方向外方へ拡開する外鍔部13bと、筒状部13aの他端から径方向内方へ狭窄する内鍔部13cとを有する。外鍔部13bは、ゴムブッシュ13自身がソケット23内に没入することを防止するものであり、内鍔部13cが、洗面器側排水管12が必要以上にソケット23内に進入することを防止するものである。   The rubber bush 13 is inserted at the tip of the socket 23 and closes the gap between the inner periphery of the socket 23 and the outer periphery of the basin-side drain pipe 12 in a watertight manner. The rubber bush 13 includes a cylindrical tubular portion 13a, an outer flange portion 13b that expands radially outward from one end thereof, and an inner flange portion 13c that narrows radially inward from the other end of the cylindrical portion 13a. And have. The outer flange 13b prevents the rubber bush 13 itself from immersing in the socket 23, and the inner flange 13c prevents the basin-side drain pipe 12 from entering the socket 23 more than necessary. To do.

このゴムブッシュ13に洗面器側排水管12が挿入されると、ワン座14が被せられ、浴槽側排水管20と洗面器側排水管12との接続部は、掩蔽される。ワン座14は、内部に、先端に係合爪14bを有する支軸14aが複数設けられ、この係合爪14bを締付フランジ24のフランジ部24bに設けられた係止部24dに係合させて取設される。   When the basin-side drain pipe 12 is inserted into the rubber bush 13, the one seat 14 is put on, and the connecting portion between the bathtub-side drain pipe 20 and the basin-side drain pipe 12 is covered. The single seat 14 is provided with a plurality of support shafts 14a having engaging claws 14b at the tip, and the engaging claws 14b are engaged with locking portions 24d provided on the flange portion 24b of the tightening flange 24. Installed.

本実施の形態に係る洗面排水装置は上記のように構成されており、以下その取付手順について、図4に示すフローチャートを参照して説明する。 浴室ユニット1は、据付現場に搬入されると、洗い場床2に排水トラップ5を取り付け、この排水トラップ5に浴槽側排水管20のトラップ側の部分を取り付ける。そして、洗い場床2設置後、浴槽3や壁パネル7等を取り付け、洗い場床2と浴槽3との間に図示しない分割床連結材を取り付けて、両者を固定する。   The wash drainage device according to the present embodiment is configured as described above, and the attachment procedure will be described below with reference to the flowchart shown in FIG. When the bathroom unit 1 is carried into the installation site, a drain trap 5 is attached to the washing floor 2, and the trap side portion of the bathtub-side drain pipe 20 is attached to the drain trap 5. Then, after the washing floor 2 is installed, the bathtub 3 and the wall panel 7 are attached, and a split floor connecting material (not shown) is attached between the washing floor 2 and the bathtub 3, and both are fixed.

以上の各作業終了後、洗面排水装置11の取り付けが開始される。それにはまず、図5に示すように、洗面器排水支持材42を分割床連結材41へねじで取り付け、浴槽側排水管20の残余のエプロン4側部分をトラップ側部分に差し込み、洗面器排水支持材42に合わせて取り付けねじにて固定する(ステップS1)。これにより、浴槽側排水管20の上下が固定され、したがって、浴槽側排水管20が所定の位置に固定されたことになる。   After completion of each of the above operations, attachment of the toilet drainage device 11 is started. First, as shown in FIG. 5, the basin drainage support member 42 is attached to the divided floor connecting member 41 with screws, the remaining apron 4 side portion of the bathtub side drain pipe 20 is inserted into the trap side portion, and the basin drainage is performed. It is fixed with a mounting screw in accordance with the support material 42 (step S1). Thereby, the upper and lower sides of the bathtub-side drain pipe 20 are fixed, and thus the bathtub-side drain pipe 20 is fixed at a predetermined position.

次に、シール部材30が取り付けられたエプロン4を浴槽3の洗い場床2側の側面に取り付ける(ステップS2)。ここで、図6に示すように、シール部材30の弾性部31bにより開口される径dよりも、ソケット23の外径Dの方が大きいので、エプロン4の取付高さと、洗面器排水支持材42の取付高さとに多少の誤差があっても、図7に示すように、弾性部31bとソケット23との間に間隙を生じることなく、弾性部31bをソケット23に水密に外嵌することができる。ここで、ソケット23の外径Dが、例えば36mmの場合、弾性部31bにより開口される径dは大凡30mmに設定される。   Next, the apron 4 to which the seal member 30 is attached is attached to the side surface of the bathtub 3 on the washing floor 2 side (step S2). Here, as shown in FIG. 6, since the outer diameter D of the socket 23 is larger than the diameter d opened by the elastic portion 31b of the seal member 30, the mounting height of the apron 4 and the basin drainage support material Even if there is a slight error in the mounting height of 42, the elastic portion 31b is fitted in the socket 23 in a watertight manner without generating a gap between the elastic portion 31b and the socket 23 as shown in FIG. Can do. Here, when the outer diameter D of the socket 23 is, for example, 36 mm, the diameter d opened by the elastic portion 31b is set to approximately 30 mm.

エプロン4が所定の位置に取り付けられると、続いて、締付フランジ24の雌ねじ部24aをソケット23先端の雄ねじ部23cに螺合させる。   When the apron 4 is attached at a predetermined position, the female screw portion 24a of the fastening flange 24 is subsequently screwed into the male screw portion 23c at the tip of the socket 23.

ここで、ソケット23の雄ねじ部23c先端とシール部材30の滑り部材33とは同じ高さ、すなわち、面一になっているので、締付フランジ24の雌ねじ部24a先端をソケット23の雄ねじ部23c先端に当接させると、図7に示すように、締付フランジ24のフランジ部24b前面がシール部材30の滑り部材33と衝合し、シール部材30の押圧が開始される(ステップS3)。したがって、この状態から締付フランジ24を螺進させると、シール部材30は必ず押圧されて、なかんずく軟質部材32は圧縮変形し、締付フランジ24のフランジ部24b前面とシール部材30の滑り部材33との間の水密性が高められる。   Here, since the tip of the male screw portion 23c of the socket 23 and the sliding member 33 of the seal member 30 are the same height, that is, flush with each other, the tip of the female screw portion 24a of the fastening flange 24 is connected to the male screw portion 23c of the socket 23. When abutting against the tip, as shown in FIG. 7, the front surface of the flange portion 24b of the tightening flange 24 abuts against the sliding member 33 of the seal member 30, and the pressing of the seal member 30 is started (step S3). Therefore, when the tightening flange 24 is screwed from this state, the seal member 30 is surely pressed, and in particular, the soft member 32 is compressed and deformed, and the front surface of the flange portion 24b of the tightening flange 24 and the sliding member 33 of the seal member 30. Watertightness between the two is increased.

この際、締付フランジ24のフランジ部24b背面には、放射状に複数の凸条24cが設けられているので、作業者は凸条24cを手に持って締付フランジ24を回動させることができるので、道具を使用することなく、容易に作業を行うことができる。   At this time, since the plurality of ridges 24c are provided radially on the rear surface of the flange portion 24b of the tightening flange 24, the operator can turn the tightening flange 24 by holding the ridges 24c. Since it can, it can work easily, without using a tool.

こうして締付フランジ24を螺進させていき、締付フランジ24の雌ねじ部24a終端がソケット23の雄ねじ部23c先端に到達すると、言い換えれば、締付フランジ24の雌ねじ部24a終端とソケット23の雄ねじ部23c先端とが面一になると、シール部材30の押圧は終了する(ステップS4)。このようにシール部材30押圧の終了位置が設定されているので、締付フランジ24のフランジ部24b前面とシール部材30の滑り部材33との間の水密性、及びソケット23の鍔部23bと貫通パッキン31の取付部31aとの間の水密性が確実に保たれ、締付不足による漏水が防止される。   In this way, the tightening flange 24 is screwed, and when the end of the female thread 24a of the tightening flange 24 reaches the end of the male thread 23c of the socket 23, in other words, the end of the female thread 24a of the tightening flange 24 and the male thread of the socket 23. When the end of the portion 23c is flush with the tip of the part 23c, the pressing of the seal member 30 is finished (step S4). Since the end position of the pressing of the seal member 30 is set in this way, the water tightness between the front surface of the flange portion 24b of the tightening flange 24 and the sliding member 33 of the seal member 30, and the flange portion 23b of the socket 23 and the through hole are penetrated. Watertightness between the packing 31 and the mounting portion 31a is reliably maintained, and water leakage due to insufficient tightening is prevented.

また、締付フランジの螺進が終了した段階で、ソケット23の雄ねじ部23cのねじ山は、折曲変形した貫通パッキン31の弾性部31bの先端から一定の距離をおいた位置で終焉する。これにより、弾性部31bがねじ山と干渉することが回避され、洗い場側の水がねじ山の谷部を経由してエプロン4裏面側へ回り込むことが防止される。   Further, when the screwing of the tightening flange is finished, the screw thread of the male screw portion 23c of the socket 23 is terminated at a position spaced apart from the tip of the elastic portion 31b of the through-packing 31 that has been bent and deformed. Thereby, it is avoided that the elastic part 31b interferes with a screw thread, and it is prevented that the water by the side of a washing place goes around to the back side of the apron 4 via the thread trough part.

以上で浴槽側排水管20側の取付が終了し、続いて洗面器側排水管12側の取付を行う。まず、ゴムブッシュ13がソケット23先端に挿入され(ステップS5)、このゴムブッシュ13に洗面器側排水管12が挿入される(ステップS6)。このゴムブッシュ13及び洗面器側排水管12は、点検等の際に取り外せるように、挿入されるだけで接着剤等で固着されない。そのため、何度も抜き差しする間に、ソケット23内面とゴムブッシュ13の筒状部13aとの間、或いはゴムブッシュ13の筒状部13aと洗面器側排水管12との間から漏水する可能性がある。しかしながら、これらの間から漏水があっても、洗い場床2側へ漏れるだけで、防水パンのないエプロン4裏面側へは漏れない。したがって、浴室ユニット1外へ漏水することは防止される。   This completes the installation on the bathtub-side drain pipe 20 side, and then performs the attachment on the basin-side drain pipe 12 side. First, the rubber bush 13 is inserted into the tip of the socket 23 (step S5), and the basin-side drain pipe 12 is inserted into the rubber bush 13 (step S6). The rubber bush 13 and the basin-side drain pipe 12 are only inserted and not fixed by an adhesive so that they can be removed at the time of inspection or the like. Therefore, water may leak from between the inner surface of the socket 23 and the cylindrical portion 13a of the rubber bush 13 or between the cylindrical portion 13a of the rubber bush 13 and the basin-side drain pipe 12 while being inserted and removed many times. There is. However, even if water leaks from between these, it only leaks to the washing floor 2 side, and does not leak to the back side of the apron 4 without the waterproof pan. Accordingly, leakage of water outside the bathroom unit 1 is prevented.

そして、最後にワン座14が、係合爪14bを締付フランジ24のフランジ部24bに設けられた係止部24dに係合させることにより、洗面器側排水管12と浴槽側排水管20との接続部に被せられて(ステップS7)、洗面排水装置11の取付が完了する。   Finally, the one seat 14 engages the engaging claw 14b with the locking portion 24d provided on the flange portion 24b of the tightening flange 24, so that the basin-side drain pipe 12 and the bathtub-side drain pipe 20 (Step S7), the attachment of the toilet drainage device 11 is completed.

次に、本実施形体に係るシール部材30の変形例について、図9を参照して説明する。本実施形体に係るシール部材30の弾性部31bは、中央が円形に開口した平円盤であるのに対し、この変形例に係るシール部材30Aは、同図に示すように、その弾性部31bは閉じた平円盤に形成され、中央に複数のスリット31cが設けられる点で、実施形態におけるものと基本的に相違し、他の構成は実施形態のものと実質的に同じである。   Next, a modification of the seal member 30 according to this embodiment will be described with reference to FIG. The elastic part 31b of the seal member 30 according to this embodiment is a flat disk having a circular opening at the center, whereas the seal member 30A according to this modification has an elastic part 31b as shown in FIG. It is fundamentally different from that in the embodiment in that it is formed in a closed flat disk and is provided with a plurality of slits 31c in the center, and other configurations are substantially the same as those in the embodiment.

このスリット31cの長さは、実施形体における開口の径dと同程度に形成され、ソケット23の外形Dよりも小さい。したがって、エプロン4の取付高さと、洗面器排水支持材42の取付高さとに多少の誤差があっても、弾性部31bとソケット23との間に間隙を生じることなく、弾性部31bをソケット23に水密に外嵌することができる。

The length of the slit DOO 31c is formed to the same extent as the diameter d of the opening in the implementation form, smaller than the outer shape D of the socket 23. Therefore, even if there is a slight error between the mounting height of the apron 4 and the mounting height of the basin drainage support member 42, the elastic portion 31 b is connected to the socket 23 without causing a gap between the elastic portion 31 b and the socket 23. It can be fitted in a watertight manner.
