Description

【０００１】
【発明の属する技術分野】
本発明は、床パンの構造に関するものである。
【０００２】
【従来の技術】
従来、床パンを裏面から補強するために、床パンの裏面から下方に向かって補強リブが突出してある。この補強リブは、床パンをスタッキング積みする際に、下段の床パンの外周部から上方に立設されている壁載置部の上面にスタッキング積みの際に載置されるスタッキング用の載置用リブを備えている。この載置用リブによって床パン同士を水平姿勢で安定良くスタッキング積みできるようにしてある。
【０００３】
ところが、床パンが設置される床スラブ上には逆梁部が突出している場合があり、特に床パンの裏面から下方に向かって補強リブを突出させた構造にあっては、補強リブが逆梁部と干渉して床パンを設置できなくなり、この場合、逆梁部に対応できる床パンを別途作製する必要が生じ、コストが高くつくという問題がある。
【０００４】
【発明が解決しようとする課題】
本発明は、上記の従来例の問題点に鑑みて発明したものであって、その目的とするところは、床パンの裏面から補強リブを突出させてスタッキング可能とした構造でありながら、逆梁部が突出している床スラブにも対応できるようにした床パンの構造を提供するにある。
【０００５】
【課題を解決するための手段】
上記課題を解決するために本発明は、床パン１の裏面から下方に向かって補強リブ２が突設されており、この補強リブ２は、浴槽部８側と洗い場側７の両方に設けられて床パン１の外周部から上方に立設されている壁載置部３の上面にスタッキング積みの際に載置されるスタッキング用の載置用リブ４と、床パン１が設置される床スラブ１０の上方に突出している逆梁部９を避けるための逆梁避け用リブ５と、浴槽部８及び洗い場７の下面に設けられる補強専用リブ６とで構成され、上記載置用リブ４と逆梁避け用リブ５とを連続して設けると共に、載置用リブ４の下端面４ａと逆梁避け用リブ５の下端面５ａとを略同じ高さレベルとし、上記洗い場７の下面の補強専用リブ６の下方への突出長Ｅを洗い場７側の載置用リブ４を構成する２つのコーナーリブの下方への突出長Ｄよりも短くしたことを特徴としており、このように構成することで、下段の床パン１の壁載置部３の上面に上段の床パン１の載置用リブ４を載置することで、複数の床パン１のスタッキング積みが可能となり、また床パン１施工時には逆梁避け用リブ５によって逆梁部９との干渉を避けることができ、逆梁部９が存在している床スラブ１０にも対応できる。また、逆梁避け用リブ５と載置用リブ４とを連続させることによって床パン１の補強リブ２が途切れることがなく、床パン１を十分に補強できるようになる。さらに洗い場７の下面の中央部側の補強専用リブ６の突出長Ｅを、洗い場７側の載置用リブ４を構成する２つのコーナーリブの突出長Ｄよりも短くしてあるので、床パン１の施工時に、洗い場７の下面の中央部側に沿って排水管１１を収納できるようになる。例えば浴槽部８側の排水と浴槽部８よりも一段高い位置にある洗い場７側の排水とを共通の排水管１１に集めて、この共通の排水管１１を洗い場７側の下面に沿って配管できるようになる。
【０００６】
また上記床パン１には洗い場７と浴槽部８とが隣接して一体に設けられ、浴槽部８よりも一段高く形成された洗い場７の下面のコーナー部から下方に向かって洗い場７側の載置用リブ４が突出しており、洗い場７の下面のコーナー部以外の部位に排水管１１を収納可能とするのが好ましく、この場合、例えば浴槽部８側の排水と洗い場７側の排水とを行う排水管１１を洗い場７側の下面に収納可能となる。
【０００７】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【０００８】
本実施形態の床パン１は、例えばユニットルームに使用され、図２に示すように、洗い場７と浴槽部８とが隣接して一体に設けられている。
【０００９】
床パン１の外周部には、上方に向かって壁載置部３が立設されている。ここでは、洗い場７の上面は浴槽部８の上面よりも一段高く形成されているが、洗い場７側の壁載置部３の突出高さを浴槽部８側の壁載置部３よりも低くすることで、洗い場７側の壁載置部３の上面と浴槽部８側の壁載置部３の上面とを同じ高さにしてある。床パン１の施工時において、壁載置部３の上面には図３に示すように、枠材１２と面板１３とからなる壁パネル１４の下面が載設される。図中の１５は壁パネル１４を固定するための固定具である。
【００１０】
床パン１の裏面には下方に向かって補強リブ２が突出されている。本例の補強リブ２は床パン１の裏面全体に亘って縦横格子状に突設されている。この補強リブ２は、床パン１の壁載置部３の上面に載置されるスタッキング用の載置用リブ４と、床スラブ１０上の逆梁部９を避けるための逆梁避け用リブ５と、補強のみを行う補強専用リブ６とで構成されている。なお補強専用リブ６は、載置用リブ４及び逆梁避け用リブ５が設けられる部位以外の浴槽部８の下面全体及び洗い場７の下面全体に亘って設けられている。
【００１１】
上記スタッキング用の載置用リブ４は、浴槽部８側と洗い場７側の両方に設けられている。図５のように洗い場７の下面は浴槽部８の下面よりも一段高く形成され、さらに壁載置部３の下面は洗い場７側及び浴槽部８側よりもそれぞれ高く形成されているが、洗い場７側の載置用リブ４の下端面４ａと浴槽部８側の載置用リブ４の下端面４ａとを略同じ高さレベルとなるように、洗い場７側の載置用リブ４及び浴槽部８側の載置用リブ４の下方への突出長Ａ（図１）を、補強専用リブ６の下方への突出長Ｂ（図１）よりもそれぞれ長くしてある。これにより、床パン１のスタッキング積み時には、図４、図５に示すように、下段の床パン１に対して上段の床パン１を傾くことなく安定良く積層できるようになっている。
【００１２】
また図４に示す例では、洗い場７側の載置用リブ４は、洗い場７の下面のコーナー部ａからそれぞれ下方に向かって突出した２つのコーナーリブａ_１，ａ_１によって形成されており、洗い場７の下面の中央部側のリブは補強専用リブ６となっている。また洗い場７の下面の中央部側の補強専用リブ６の突出長Ｅ（図２）を洗い場７側の載置用リブ４の突出長Ｄ（図２）よりも短くしてあり、これにより、洗い場７の下面側に沿って排水管１１が収納可能となっている。さらに、図５に示すように、浴槽部８側の載置用リブ４の下端面４ａと洗い場７側の載置用リブ４の下端面４ａとは略同じ高さレベルとなっており、これによりスタッキング積み時には下段の床パン１の壁載置部３上面に水平姿勢で安定良く載置できるようになっている。
【００１３】
逆梁避け用リブ５は、本例では浴槽部８側の載置用リブ４の隣りに隣接し、浴槽部８側の下面の幅方向全長に亘って設けらている。なお、逆梁避け用リブ５の形成位置は、図１、図２、図４の例に限られるものではなく、適宜変更可能である。この逆梁避け用リブ５は、図１に示すように、床スラブ１０上に突出している逆梁部９を避けるためのものであり、補強専用リブ６の突出長Ｂよりも突出長Ｆ（図１）が短くなるように補強リブ２の一部を切除して形成されている。逆梁避け用リブ５は載置用リブ４と連続して設けられており、逆梁避け用リブ５によって床パン１は逆梁部９が存在している床スラブ１０にも設置可能となっている。ここで、逆梁避け用リブ５の突出長Ｆを短くしすぎると補強リブとしての機能が失われ、逆に突出長Ｆを長くしすぎると逆梁部９と干渉しやすくなる。そこで、本発明では、逆梁避け用リブ５の下端面５ａがスタッキング用の載置用リブ４の下端面４ａと略同じ高さレベルとなるように、逆梁避け用リブ５の突出長Ｄを決めている。これにより、逆梁避け用リブ５の補強リブとしての機能を確保しながら、同時に逆梁部９との干渉防止を図ることができるものである。
【００１４】
しかして、上記構成の床パン１は、浴槽部８側の壁載置部３の上面と浴槽部８側の壁載置部３の上面とが同じ高さとなっており、且つ、床パン１の裏面に突出している浴槽部８側の載置用リブ４の下端面４ａと洗い場７側の載置用リブ４の下端面４ａとが同じ高さとなっている。従って、図５に示すように、スタッキング積み時には、上段の床パン１の浴槽部８側の載置用リブ４の下端面４ａを下段の床パン１の浴槽部８側の壁載置部３の上面に載置し、上段の床パン１の洗い場側７側の載置用リブ４の下端面４ａを下段の床パン１の洗い場７側の壁載置部３の上面に載置することで、図４に示すように、複数の床パン１を水平姿勢で安定良くスタッキング積みができるようになる。またスタッキング積み時には図５に示すように、上段の床パン１の浴槽部８側の補強専用リブ６が下段の床パン１の浴槽部８内に所定の隙間をあけて配置され、上段の床パン１の洗い場７側の補強専用リブ６が下段の床パン１の洗い場７内に所定の隙間をあけて配置されるものである。
【００１５】
一方、床パン１の施工時において、浴槽部８側の載置用リブ４の隣りには、床スラブ１０から突出している逆梁部９を避けるための逆梁避け用リブ５が形成されているので、図１、図２のように床パン１を逆梁部９が突出している床スラブ１０上に設置する際には、逆梁避け用リブ５によって逆梁部９との干渉を避けることができる。従って、床パン１は逆梁部９が存在している床スラブ１０にも、存在していない床スラブ１０にもいずれも設置可能となるので、従来のように逆梁部９に対応できる専用の床パン１を別途作製する必要がなく、コスト削減を図ることができる。そのうえ、逆梁避け用リブ５はその突出長Ｆが短いとはいえ、載置用リブ４の下端面４ａと略同じ高さレベルまで突出しているので、逆梁避け用リブ５においても補強リブとしての機能が確保されており、しかもこの逆梁避け用リブ５を挟んで載置用リブ４と補強専用リブ６とが連続して一体形成されているので、床パン１の補強リブ２が途切れることがなく、床パン１を十分に補強できるものである。
【００１６】
また、洗い場７の下面の中央部側の補強専用リブ６の突出長Ｅ（図２）を、洗い場７側の載置用リブ４を構成する２つのコーナーリブの突出長Ｄ（図２）よりも短くしてあるので、洗い場７の下面の中央部側に沿って排水管１１を収納できるようになる。例えば浴槽部８側の排水と浴槽部８よりも一段高い位置にある洗い場７側の排水とを共通の排水管１１に集めて、この共通の排水管１１を洗い場７側の下面に沿って配管できるようになる。従って、床パン１の裏面のデッドスペースを有効に利用できると共に、排水管１１の引き出し方向を三方向（図４の矢印ニ、ホ、ヘで示す方向）のいずれかに選択できるので、現場状況に応じた配管作業を容易に行うことができるものである。
【００１７】
【発明の効果】
上述のように請求項１記載の発明にあっては、床パンの裏面から下方に向かって補強リブが突設されており、この補強リブは、浴槽部側と洗い場側の両方に設けられて床パンの外周部から上方に立設されている壁載置部の上面にスタッキング積みの際に載置されるスタッキング用の載置用リブと、床パンが設置される床スラブの上方に突出している逆梁部を避けるための逆梁避け用リブと、浴槽部及び洗い場の下面に設けられる補強専用リブとで構成され、上記載置用リブと逆梁避け用リブとを連続して設けると共に、載置用リブの下端面と逆梁避け用リブの下端面とを略同じ高さレベルとし、上記洗い場の下面の補強専用リブの下方への突出長を洗い場側の載置用リブを構成する２つのコーナーリブの下方への突出長よりも短くしたので、下段の床パンの壁載置部の上面に上段の床パンの載置用リブを載置することで、複数の床パンのスタッキング積みが可能となり、また床パンを逆梁部が突出している床スラブ上に設置する際には、逆梁避け用リブによって逆梁部との干渉を避けることができるので、逆梁部が存在している床スラブにも対応できる。従って、従来のように逆梁部に対応するための専用の床パンを別途作製する必要がなく、コスト削減を図ることができる。そのうえ、逆梁避け用リブと載置用リブとを連続させることによって床パンの補強リブが途切れることがなく、床パンを十分に補強できるものである。さらに洗い場の下面の補強専用リブの突出長を、洗い場側の載置用リブを構成する２つのコーナーリブの突出長よりも短くしてあるので、床パンの施工時に、洗い場の下面の中央部側に沿って排水管を収納できるようになる。例えば浴槽部側の排水と浴槽部よりも一段高い位置にある洗い場側の排水とを共通の排水管に集めて、この共通の排水管を洗い場側の下面に沿って配管できるようになる。従って、床パンの裏面のデッドスペースを有効に利用できると共に、排水管の引き出し方向を選択できるので、現場状況に応じた配管作業を容易に行うことができるものである。
【００１８】
また請求項２記載の発明は、請求項１記載の効果に加えて、床パンには洗い場と浴槽部とが隣接して一体に設けられ、浴槽部よりも一段高く形成された洗い場の下面のコーナー部から下方に向かって洗い場側の載置用リブが突出しており、洗い場の下面のコーナー部以外の部位に排水管を収納可能としたので、例えば浴槽部側の排水と洗い場側の排水とを行う排水管を洗い場側の下面に収納できるようになり、床パンの裏面のデッドスペースを有効に利用できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor pan structure.
[0002]
[Prior art]
Conventionally, in order to reinforce the floor pan from the back surface, a reinforcing rib protrudes downward from the back surface of the floor pan. This reinforcing rib is used for stacking the stacking of the floor pans on the upper surface of the wall mounting portion which is erected upward from the outer periphery of the lower floor pan. It is provided with a rib. The mounting ribs allow the floor pans to be stably stacked in a horizontal posture.
[0003]
However, there are cases where the inverted beams protrude from the floor slab on which the floor pan is installed, particularly in a structure in which the reinforcing ribs are projected downward from the back surface of the floor pan. The floor pan cannot be installed due to the interference with the beam portion. In this case, it is necessary to separately manufacture a floor pan corresponding to the reverse beam portion, and there is a problem that the cost is high.
[0004]

Further, the floor pan 1 is integrally provided with a washing place 7 and a bathtub section 8 adjacent to each other, and is mounted on the washing place 7 side downward from a corner portion of a lower surface of the washing place 7 formed one step higher than the bathtub section 8. It is preferable that the installation rib 4 protrudes and the drain pipe 11 can be stored in a portion other than the corner portion on the lower surface of the washing place 7. In this case, for example, the drainage of the bathtub section 8 and the drainage of the washing place 7 are separated. The drainage pipe 11 to be performed can be stored in the lower surface on the washing place 7 side.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0008]
The floor pan 1 of the present embodiment is used, for example, in a unit room, and as shown in FIG. 2, a washing place 7 and a bathtub section 8 are provided adjacently and integrally.
[0009]
On the outer peripheral portion of the floor pan 1, a wall mounting portion 3 is erected upward. Here, the upper surface of the washing room 7 is formed one step higher than the upper surface of the bathtub unit 8, but the projecting height of the wall mounting unit 3 on the washing room 7 side is lower than the wall mounting unit 3 on the bathtub unit 8 side. By doing so, the upper surface of the wall mounting portion 3 on the side of the washing room 7 and the upper surface of the wall mounting portion 3 on the side of the bathtub portion 8 are at the same height. When the floor pan 1 is constructed, the lower surface of the wall panel 14 composed of the frame member 12 and the face plate 13 is placed on the upper surface of the wall placing portion 3 as shown in FIG. Reference numeral 15 in the figure denotes a fixing device for fixing the wall panel 14.
[0010]
A reinforcing rib 2 protrudes downward from the back surface of the floor pan 1. The reinforcing ribs 2 of the present example are provided in a vertical and horizontal lattice shape over the entire back surface of the floor pan 1. The reinforcing rib 2 includes a stacking mounting rib 4 mounted on the upper surface of the wall mounting portion 3 of the floor pan 1 and a reverse beam avoiding rib for avoiding the reverse beam 9 on the floor slab 10. 5 and a rib 6 for reinforcement only for reinforcement. The reinforcing exclusive rib 6 is provided over the entire lower surface of the bathtub portion 8 and the entire lower surface of the washing place 7 except for the portion where the mounting rib 4 and the reverse beam avoiding rib 5 are provided.
[0011]
The mounting ribs 4 for stacking are provided on both the bathtub section 8 side and the washing place 7 side. As shown in FIG. 5, the lower surface of the washing room 7 is formed one step higher than the lower surface of the bathtub unit 8, and the lower surface of the wall mounting unit 3 is formed higher than the washing room 7 side and the bathtub unit 8 side. The mounting rib 4 and the bathtub on the washing room 7 side such that the lower end surface 4a of the mounting rib 4 on the 7 side and the lower end surface 4a of the mounting rib 4 on the bathtub section 8 are at substantially the same height level. The downward projecting length A (FIG. 1) of the mounting rib 4 on the part 8 side is longer than the downward projecting length B (FIG. 1) of the reinforcing rib 6. Thereby, when stacking the floor pans 1, as shown in FIGS. 4 and 5, the upper floor pan 1 can be stably stacked on the lower floor pan 1 without tilting.
[0012]
In addition, in the example shown in FIG. 4, the mounting ribs 4 on the washing room 7 side are formed by two corner ribs a ₁ , a ₁ protruding downward from corners a on the lower surface of the washing room 7, respectively. The rib at the center of the lower surface of the washing place 7 is a rib 6 for reinforcement. Further, the protruding length E (FIG. 2) of the reinforcing exclusive rib 6 on the central portion side of the lower surface of the washing place 7 is shorter than the protruding length D (FIG. 2) of the mounting rib 4 on the washing place 7 side. The drain pipe 11 can be stored along the lower surface side of the washing place 7. Further, as shown in FIG. 5, the lower end face 4a of the mounting rib 4 on the bathtub section 8 side and the lower end face 4a of the mounting rib 4 on the washing place 7 side have substantially the same height level. Therefore, during stacking, it can be stably mounted on the upper surface of the wall mounting portion 3 of the lower floor pan 1 in a horizontal posture.
[0013]
In this example, the ribs 5 for avoiding the reverse beam are provided adjacent to the mounting ribs 4 on the bathtub section 8 side, and are provided over the entire length in the width direction of the lower surface on the bathtub section 8 side. In addition, the formation position of the rib 5 for avoiding the reverse beam is not limited to the examples of FIGS. 1, 2, and 4, and can be appropriately changed. As shown in FIG. 1, the rib 5 for avoiding the reverse beam is for avoiding the reverse beam portion 9 projecting on the floor slab 10, and has a projection length F ( The reinforcing rib 2 is formed by cutting a part of the reinforcing rib 2 so as to shorten the length of FIG. The reverse beam avoiding rib 5 is provided continuously with the mounting rib 4, and the floor pan 1 can be installed on the floor slab 10 where the reverse beam portion 9 exists by the reverse beam avoiding rib 5. ing. Here, if the protruding length F of the reverse beam avoiding rib 5 is too short, the function as a reinforcing rib is lost. Conversely, if the protruding length F is too long, it easily interferes with the reverse beam portion 9. Therefore, in the present invention, the projecting length D of the reverse beam avoiding rib 5 is set so that the lower end surface 5a of the reverse beam avoiding rib 5 is at substantially the same height level as the lower end surface 4a of the stacking mounting rib 4. Have decided. Thereby, it is possible to secure the function of the reverse beam avoiding rib 5 as a reinforcing rib, and at the same time, to prevent interference with the reverse beam portion 9.
[0014]
In the floor pan 1 having the above configuration, the upper surface of the wall mounting portion 3 on the side of the bathtub 8 and the upper surface of the wall mounting portion 3 on the side of the bathtub 8 are at the same height. The lower end surface 4a of the mounting rib 4 on the side of the bathtub 8 protruding from the back surface of the bathtub 8 and the lower end surface 4a of the mounting rib 4 on the side of the washing place 7 are at the same height. Therefore, as shown in FIG. 5, during stacking, the lower end surface 4a of the mounting rib 4 on the side of the bathtub 8 of the upper floor pan 1 is placed on the wall mounting part 3 of the lower floor pan 1 on the side of the bathtub 8. And the lower end surface 4a of the placing rib 4 on the washing floor side 7 of the upper floor pan 1 is placed on the upper surface of the wall placing part 3 on the washing floor 7 side of the lower floor pan 1. Thus, as shown in FIG. 4, the plurality of floor pans 1 can be stably stacked in a horizontal posture. In stacking, as shown in FIG. 5, the reinforcing ribs 6 on the side of the bathtub section 8 of the upper floor pan 1 are arranged in the bathtub section 8 of the lower floor pan 1 with a predetermined gap, and the upper floor pan 1 Reinforcing ribs 6 on the side of the washing pan 7 of the bread 1 are arranged in the washing pan 7 of the lower floor pan 1 with a predetermined gap.
[0015]
On the other hand, at the time of construction of the floor pan 1, a rib 5 for avoiding the reverse beam for avoiding the reverse beam portion 9 protruding from the floor slab 10 is formed next to the mounting rib 4 on the bathtub portion 8 side. When the floor pan 1 is installed on the floor slab 10 from which the inverted beam portion 9 protrudes as shown in FIGS. 1 and 2, the interference with the inverted beam portion 9 is avoided by the inverted beam avoiding ribs 5. be able to. Therefore, the floor pan 1 can be installed on both the floor slab 10 where the back beam 9 is present and on the floor slab 10 where the back beam 9 is not present. It is not necessary to separately manufacture the floor pan 1, and the cost can be reduced. In addition, although the projection length F of the reverse beam avoiding rib 5 is short, it protrudes to substantially the same level as the lower end surface 4a of the mounting rib 4, so that the reinforcing rib is also used in the reverse beam avoiding rib 5. Since the mounting ribs 4 and the reinforcing ribs 6 are continuously formed integrally with the reverse beam avoiding ribs 5 therebetween, the reinforcing ribs 2 of the floor pan 1 The floor pan 1 can be sufficiently reinforced without interruption.
[0016]
Further, the protruding length E (FIG. 2) of the reinforcing rib 6 on the central portion side of the lower surface of the washing place 7 is determined from the protruding length D (FIG. 2) of the two corner ribs constituting the mounting rib 4 on the washing place 7 side. Is also shortened, so that the drain pipe 11 can be stored along the central portion of the lower surface of the washing place 7. For example, the drainage from the bathtub section 8 and the drainage from the washing place 7 located at a position higher than the bathtub section 8 are collected in a common drainage pipe 11, and the common drainage pipe 11 is piped along the lower surface on the washing place 7 side. become able to. Therefore, the dead space on the back surface of the floor pan 1 can be effectively used, and the drain pipe 11 can be drawn out in one of three directions (indicated by arrows D, E, and F in FIG. 4). The piping work according to the above can be easily performed.
[0017]
【The invention's effect】
As described above, according to the first aspect of the present invention, the reinforcing ribs are protruded downward from the back surface of the floor pan, and the reinforcing ribs are provided on both the bathtub part side and the washing place side. A stacking mounting rib that is mounted on the upper surface of the wall mounting portion that stands upward from the outer periphery of the floor pan when stacking and stacking, and protrudes above a floor slab where the floor pan is installed. It is composed of a rib for avoiding a reverse beam that is provided, and a rib for exclusive use of reinforcement provided on a lower surface of a bathtub and a washing place, and a rib for placing and a rib for avoiding a reverse beam are provided continuously. with, mounting a rib of the lower end surface opposite the beam avoiding rib substantially the same height level and the lower end surface of the washing place side of the mounting ribs protruding length of the lower surface of the reinforcing dedicated ribs below the washing area since shorter than the projection length of the two corner rib of the lower constituting, By mounting the mounting ribs of the upper floor pan on the upper surface of the wall mounting part of the floor pan, stacking of a plurality of floor pans is possible, and the inverted beams protrude from the floor pan. When installed on a floor slab, the ribs for avoiding the reverse beam can avoid interference with the reverse beam, so that it is possible to cope with a floor slab having the reverse beam. Therefore, there is no need to separately manufacture a dedicated floor pan corresponding to the inverted beam portion as in the related art, and the cost can be reduced. Moreover, by making the ribs for avoiding the reverse beam and the mounting ribs continuous, the reinforcing ribs of the floor pan are not interrupted, and the floor pan can be sufficiently reinforced. Furthermore, the projecting length of the reinforcing ribs on the lower surface of the washing area is shorter than the projecting lengths of the two corner ribs constituting the mounting ribs on the washing area side. The drain can be stored along the side. For example, the drainage on the side of the bathtub and the drainage on the side of the washing place located one step higher than the bathtub are collected in a common drainage pipe, and the common drainage pipe can be piped along the lower surface on the side of the washing place.
