浴室ユニットの排水構造及び施工方法Drainage structure of bathroom unit and construction method
 本開示は、床部から排水管に排水を導く浴室ユニットの排水構造に関する。 The present disclosure relates to a drainage structure of a bathroom unit that leads drainage from a floor to a drainage pipe.
 浴室ユニットの床部にはシャワー排水やトイレ排水等を外部に排出するための排水口が設けられる。例えば、特許文献1には、防水パンの洗い場側方に浴槽を設置するようにした浴室ユニットの排水装置において以下の構成が記載されている。防水パンには、浴槽の排水栓に対応する下方位置に貫通孔部を形成する。貫通孔部に排水用ソケットを嵌入して排水ソケットに排水トラップを防水パンの裏側で連結する。可撓性をもつ連結継手により、浴槽の排水栓と排水用ソケットを連結する。 The floor of the bathroom unit is provided with a drainage port for discharging shower drainage and toilet drainage to the outside. For example, Patent Document 1 describes the following configuration in a drainage device of a bathroom unit in which a bathtub is installed on the side of a washing pan of a waterproof pan. The waterproof pan is provided with a through hole at a lower position corresponding to the drainage plug of the bathtub. Insert a drainage socket into the through hole and connect the drainage trap to the drainage socket on the back side of the waterproof pan. A flexible connection joint connects the bathtub drain plug and the drain socket.
 浴室ユニットの床部は、湿式工法や乾式工法によって床スラブに固定される。次に、図面を参照して湿式工法と乾式工法の従来例について説明する。まず、図14A~図14Eを参照して浴室ユニットの床部を湿式工法によって施工する例について説明する。集合住宅等の場合、排水口に接続される排水管は、コンクリートスラブ等の床スラブを通して階下へ導く経路が一般的である。まず、図14Aに示すように、開口部101,102を有する床スラブ10を形成し、図14Bに示すように、排水口側排水管11を開口部101に通した後、モルタル13で開口部を埋めるようにして固定するとともに、トイレ側排水管12を開口部102に固定する。図14Cに示すように、コンクリート150を床スラブ10に施工して床部120を配置する。図14Dに示すように、排水口側排水管11及びトイレ側排水管12の長さを揃え、目皿受け106を排水口側排水管11に取り付けるとともに、トイレ側排水管12に排水構造108を取り付ける。なお、排水構造108を使用せず、トイレ側排水管12を適当な高さに切断しトイレと直接接続することもある。図14Eには、図14Dで説明した工程の後、排水構造108を介して便器7とトイレ側排水管12が接続された浴室ユニットが示されている。 The floor of the bathroom unit is fixed to the floor slab by a wet method or a dry method. Next, conventional examples of the wet method and the dry method will be described with reference to the drawings. First, an example in which the floor portion of the bathroom unit is constructed by a wet method will be described with reference to FIGS. 14A to 14E. In the case of a housing complex or the like, a drainage pipe connected to the drainage port generally has a path leading downstairs through a floor slab such as a concrete slab. First, as shown in FIG. 14A, the floor slab 10 having the openings 101 and 102 is formed, and as shown in FIG. 14B, the drainage side drain pipe 11 is passed through the opening 101 and then the mortar 13 And the toilet-side drain pipe 12 is fixed to the opening 102. As shown in FIG. 14C, concrete 150 is applied to the floor slab 10 to arrange the floor portion 120. As shown in FIG. 14D, the drain hole side drain pipe 11 and the toilet side drain pipe 12 have the same length, and the pan receiver 106 is attached to the drain port side drain pipe 11, and the drainage structure 108 is attached to the toilet side drain pipe 12. Attach. In addition, without using the drainage structure 108, the toilet-side drainage pipe 12 may be cut at an appropriate height and directly connected to the toilet. FIG. 14E shows a bathroom unit in which the toilet 7 and the toilet-side drainage pipe 12 are connected via the drainage structure 108 after the process described in FIG. 14D.
 次に、図15に示す横引き配管を用いた乾式工法による施工例について説明する。図15に示す方法では、床スラブ10の上で水平方向に延びる配管211を配置し、この配管211を床部220の排水口206やトイレ用の排水構造207に接続する。乾式工法では、工場出荷時に排水口206、排水構造207、配管211を床部に接続しておくことも可能であり、湿式工法に対して作業性及び工期短縮のメリットがある。 Next, the example of construction by the dry construction method using the horizontal pulling piping shown in FIG. 15 will be described. In the method shown in FIG. 15, a pipe 211 extending horizontally on the floor slab 10 is disposed, and the pipe 211 is connected to the drainage port 206 of the floor 220 and the drainage structure 207 for the toilet.

 作業性の向上や工期の短縮を実現するために図14A~図14Eを参照して説明したような湿式工法からユニットバスを用いた乾式工法に変更することが考えられる。しかし、図14A~図14Eで示したような床スラブ10の下から排水管が延び出るような構成では、予め工場で床部に排水管を取り付けると輸送時や床部設置時に排水管が他の部材に干渉し、輸送性や作業性が低下するおそれがある。一方で、図15で説明した排水管を横引きする方法は、乾式工法ではあるものの、床部の下に配管を通す空間が必要になるため、湿式工法に比べて浴室床が高くなって浴室ドアの出入り口段差も高くなってしまう。また、図14A~図14Eに示すような床スラブから立ち上った排水管のように自由に取り回すことが難しい建物では、製品誤差や施工誤差等によって生じた排水管と床部の位置ずれの対応を現場で行う必要がある。特許文献1は、可撓性を有する接続継手による歪みを吸収できるとしているものの、接続継手が変形によって負荷を受けることになる上、床部の上方で発生した歪みを吸収できたとしても、床部の下方で床スラブから立ち上る排水管と床部の接続部分の位置ずれに対応することが難しい。特許文献1は、そもそも浴槽の排水構造に関するものであり、図14A~図14Eで示したような床スラブから立ち上がる排水管を前提としているものではなかった。 It is conceivable to change the wet process as described with reference to FIGS. 14A to 14E to a dry process using a unit bus in order to improve the workability and shorten the construction period. However, in the configuration in which the drainage pipe extends from under the floor slab 10 as shown in FIGS. 14A to 14E, if the drainage pipe is attached to the floor in advance at the factory, the drainage pipe is not And may interfere with transport properties and workability. On the other hand, although the method of horizontally pulling the drainage pipe described in FIG. 15 is a dry method, it requires a space through which piping passes below the floor, so the bathroom floor becomes higher than the wet method and the bathroom The height difference at the door entrance also increases. In addition, in a building where it is difficult to manage freely, such as drainage pipes rising from floor slabs as shown in FIG. 14A to FIG. 14E, measures for positional deviation of drainage pipes and floor caused by product errors or construction errors. Needs to be done on site. Although Patent Document 1 is capable of absorbing the strain due to the flexible connection joint, the connection joint is subjected to a load by deformation, and the strain generated above the floor can be absorbed even if the floor is It is difficult to cope with the positional deviation of the connection between the drainage pipe and the floor part rising from the floor slab below the part. Patent Document 1 relates primarily to the drainage structure of a bathtub, and does not presuppose a drainage pipe rising from a floor slab as shown in FIGS. 14A to 14E.

 次に、シャワーエリア2に設けられる排水構造6の構成について説明する。図2は、本実施形態のシャワーエリア2の排水構造6の構成を示す分解断面図である。図3は、本実施形態のシャワーエリア2の排水構造6の設置状態を示す断面図である。 Next, the configuration of the drainage structure 6 provided in the shower area 2 will be described. FIG. 2 is an exploded cross-sectional view showing the configuration of the drainage structure 6 of the shower area 2 of the present embodiment. FIG. 3: is sectional drawing which shows the installation state of the drainage structure 6 of the shower area 2 of this embodiment.
 図2及び図3に示すように、排水構造6が接続される排水口側排水管11は、その上端部が床スラブ10の上面よりも上方に位置した状態で該床スラブ10に固定される。床スラブ10は、例えば鉄筋コンクリート等によって構成される床構造である。本実施形態では、防水性及び防音性の観点からモルタル13を介して排水口側排水管11が床スラブ10に保持されている。また、床部20の排水口21が形成される部分が凹部25となっており、排水口21は、周囲よりも一段下がった場所に位置する。床部20の凹部25の外側にはフロアタイル26が配置されている。なお、床部20は、フロアタイル26によって床面を形成するものに限定されるわけではない。例えば、床部の上面が直接床面を形成する構成であってもよい。 As shown in FIG. 2 and FIG. 3, the drainage side drain pipe 11 to which the drainage structure 6 is connected is fixed to the floor slab 10 with the upper end portion thereof positioned above the upper surface of the floor slab 10 . The floor slab 10 is a floor structure configured of, for example, reinforced concrete. In the present embodiment, the drainage side drainage pipe 11 is held by the floor slab 10 via the mortar 13 from the viewpoint of waterproofness and soundproofness. Moreover, the part in which the drainage port 21 of the floor part 20 is formed becomes the recessed part 25, and the drainage port 21 is located in the place 1 stage lower than circumference | surroundings. A floor tile 26 is disposed outside the recess 25 of the floor 20. In addition, the floor part 20 is not necessarily limited to what forms a floor surface by the floor tile 26. FIG. For example, the upper surface of the floor portion may directly form the floor surface.
 排水構造6の構成について説明する。本実施形態の排水構造6は、排水口側排水管11に配置される目皿アダプター61と、目皿アダプター61に被せられる目皿枠62と、目皿枠62の上側に置かれる目皿カバー63と、を主要な構成として備える。 The configuration of the drainage structure 6 will be described. The drainage structure 6 of the present embodiment includes a tray adapter 61 disposed in the outlet side drain pipe 11, a tray frame 62 placed over the tray adapter 61, and a tray cover placed on the upper side of the tray frame 62. And 63 as the main components.
 目皿アダプター61は、排水口側排水管11の上端部に設置される。本実施形態の目皿アダプター61は、塩化ビニル等の樹脂材料によって構成される。 The tray adapter 61 is installed at the upper end of the outlet-side drain pipe 11. The tray adapter 61 of the present embodiment is made of a resin material such as vinyl chloride.
 図3から図5に示すように、目皿アダプター61は、円筒状に形成されるアダプター筒部610と、アダプター筒部610の上端部に形成される外側フランジ611と、アダプター筒部610の上端部に形成される内側フランジ612と、から構成される。アダプター筒部610、外側フランジ611及び内側フランジ612は一体的な部材として構成される。 As shown in FIGS. 3 to 5, the tray adapter 61 includes an adapter cylinder 610 formed in a cylindrical shape, an outer flange 611 formed on the upper end of the adapter cylinder 610, and an upper end of the adapter cylinder 610. And an inner flange 612 formed on the part. The adapter cylinder 610, the outer flange 611 and the inner flange 612 are configured as an integral member.
 内側フランジ612によって目皿アダプター61上端部の開口部615が形成される。本実施形態では、開口部615の大きさがアダプター筒部610の内径よりも小さく形成されている。また、設置状態では、内側フランジ612の下面が排水口側排水管11の上端面と間隔をあけて対向する位置関係となっている。なお、内側フランジ612と排水口側排水管11が上下方向で隙間なく配置されてもよいが、現場での排水口側排水管11の切断作業において、切断面が水平にならない等のバラツキを吸収する観点では、内側フランジ612の下面が排水口側排水管11の上端面とが間隔をあけて配置されることが好ましい。 The inner flange 612 forms an opening 615 at the upper end of the tray adapter 61. In the present embodiment, the size of the opening 615 is smaller than the inner diameter of the adapter cylinder 610. Further, in the installed state, the lower surface of the inner flange 612 is in a positional relationship opposed to the upper end surface of the drain side drain pipe 11 at an interval. In addition, although the inner flange 612 and the drainage port side drainage pipe 11 may be arrange | positioned without a clearance in the up-down direction, in the cutting operation | work of the drainage port side drainage pipe 11 in a field, the variation that a cut surface becomes horizontal etc. is absorbed In view of the above, it is preferable that the lower surface of the inner flange 612 and the upper end surface of the drain side drain pipe 11 be spaced apart from each other.
 目皿枠62は、目皿アダプター61の上端部に設置される。本実施形態の目皿枠62は、ステンレス等の金属又はFRP等の樹脂によって構成される。 The tray frame 62 is installed at the upper end of the tray adapter 61. The eyeglass frame 62 of the present embodiment is made of metal such as stainless steel or resin such as FRP.
 図6に示すように、目皿枠62は、平面視において矩形の環状に形成されており、中央に矩形の開口部625が形成される。図3に示すように、目皿アダプター61の下部中央には開口部625に連通する角筒部621が形成されている。なお、開口部625は、矩形に限られるわけでなく、円形やその他の多角形等であってもよい。また、本実施形態では、角筒部621の下端位置(図3中の上側の二点鎖線)が、排水口側排水管11の上端位置(図3中下側の二点鎖線)よりも上方に位置するように構成されるが、この構成に限定されない。排水口側排水管11と目皿アダプター61の間への水の侵入を防止する観点から、目皿枠62の角筒部621の下端位置が排水口側排水管11の上端位置よりも下方に位置する構成としてもよい。例えば、角筒部621自体を下に延長したり、角筒部621の下部に別部材を取り付けたりすることにより、角筒部621の下端位置が排水口側排水管11の上端位置よりも下側に位置させることができる。また、排水口側排水管11の切断作業において排水口側排水管11の上部を長めに残して切断することにより、排水口側排水管11の上端位置が角筒部621の下端位置よりも上方に位置させるようにしてもよい。あるいは、内側フランジ612の下端面を下側に延長することにより、排水口側排水管11と目皿アダプター61の間への水の侵入を防止する構成としてもよい。 As shown in FIG. 6, the eyeglass frame 62 is formed in a rectangular ring shape in a plan view, and a rectangular opening 625 is formed at the center. As shown in FIG. 3, a rectangular tube portion 621 communicating with the opening 625 is formed at the center of the lower portion of the mesh adapter 61. The opening 625 is not limited to a rectangle, and may be a circle, another polygon, or the like. Further, in the present embodiment, the lower end position (upper two-dot chain line in FIG. 3) of the rectangular tube portion 621 is higher than the upper end position (lower two-dot chain line in FIG. 3) of the drain side drain pipe 11. However, the present invention is not limited to this configuration. From the viewpoint of preventing water from entering between the drain side drain pipe 11 and the eyelet adapter 61, the lower end position of the square tube portion 621 of the eye pan frame 62 is lower than the upper end position of the drain side drain pipe 11. It may be configured to be located. For example, the lower end position of the rectangular tube portion 621 is lower than the upper end position of the drain side drain pipe 11 by extending the rectangular tube portion 621 itself downward or attaching another member to the lower portion of the rectangular tube portion 621. It can be located on the side. Further, the upper end position of the drainage port side drainage pipe 11 is higher than the lower end position of the rectangular tube portion 621 by cutting the drainage port side drainage pipe 11 while leaving the upper part of the drainage port side drainage pipe 11 longer. It may be located at Alternatively, the lower end surface of the inner flange 612 may be extended downward to prevent water from entering between the outlet-side drain 11 and the tray adapter 61.
 目皿枠62における開口部625の周囲には、スロープ622が形成される。目皿枠62のスロープ622は、上端面から開口部625に近づくにつれて下がるように傾斜している。また、本実施形態のスロープ622は、開口部625の4辺に対応して4つの領域に分かれている。 A slope 622 is formed around the opening 625 in the eyeglass frame 62. The slope 622 of the eyeglass frame 62 is inclined so as to decrease from the upper end face toward the opening 625. Further, the slopes 622 in the present embodiment are divided into four regions corresponding to the four sides of the opening 625.
 図7に示すように、目皿枠62の下端部には、床部20の上面に対向する設置面623が設けられる。設置面623は、背面視において目皿枠62の4辺のそれぞれ形成されている。 As shown in FIG. 7, an installation surface 623 facing the upper surface of the floor portion 20 is provided at the lower end portion of the mesh frame 62. The installation surface 623 is formed on each of the four sides of the eyeglass frame 62 in a rear view.
 目皿カバー63は、目皿枠62に載置される。本実施形態の目皿カバー63は、ステンレス等の金属又はFRP等の樹脂によって構成される。 The tray cover 63 is placed on the tray frame 62. The tray cover 63 of the present embodiment is made of metal such as stainless steel or resin such as FRP.
 図8に示すように、目皿カバー63は、貫通孔630,631が形成される矩形のパンチングメタルである。本実施形態の目皿カバー63は、円形の貫通孔631が縦横に並んで形成されており、中央に形成される貫通孔630が他の貫通孔631よりも大きな径となっている。清掃作業等では、他の貫通孔631よりも径の大きい中央の貫通孔630に指や器具を差し入れることで容易に目皿カバー63を取り外すことができる。なお、貫通孔630,631の形状や配列は、適宜変更することができる。 As shown in FIG. 8, the mesh cover 63 is a rectangular punching metal in which the through holes 630 and 631 are formed. In the tray cover 63 of the present embodiment, circular through holes 631 are formed vertically and horizontally, and the through hole 630 formed at the center has a diameter larger than that of the other through holes 631. In the cleaning operation and the like, the eyeglass cover 63 can be easily removed by inserting a finger or a tool into the central through hole 630 having a diameter larger than that of the other through holes 631. The shape and arrangement of the through holes 630 and 631 can be changed as appropriate.
