Description

本発明は、主として集合住宅用建造物の排水配管方法に関するものである。   The present invention mainly relates to a drainage piping method for buildings for apartment buildings.

従来型の建造物の勾配排水方法では、横引き管に所定の勾配を取るため、横引き管が長い場合には床下も大きくすることで対応していた。従って、この勾配を利用した排水方法にあっては、横引き管の長さが長い配管設計では床下空間を多大に取る必要があり、階高が上がったり、縦方向への居住空間が狭くなっていた。   In the conventional gradient drainage method for buildings, in order to obtain a predetermined gradient in the horizontal pipe, when the horizontal pipe is long, the underfloor is enlarged. Therefore, in the drainage method using this gradient, it is necessary to take a lot of space under the floor in the piping design with a long horizontal pulling pipe, and the floor height rises or the living space in the vertical direction is narrow. It was.

かかる欠点を解消すべく、サイフォン排水方法が提案されている(特許文献1)。サイフォン排水方法の概要は、排水立て管、水回り器具、横引き管、立て管への合流部からなり、水回り器具には管径が20A程度のパイプが接続され、床に対して無勾配で配管され、これが途中で合流することなく、合流部へ接続されるものである。そして、この合流部は水回り器具がある床(階)よりも低い位置(好ましくは1階分階下)に形成されたものであり、その水頭(落差)Hsの分だけサイフォン力が生じるものであり、パイプ内にはエアがなく排水は満流流れにて排水されることとなる。   In order to eliminate such drawbacks, a siphon draining method has been proposed (Patent Document 1). The outline of the siphon drainage method consists of a drainage standpipe, plumbing device, horizontal pulling tube, and a junction to the standpipe. A pipe with a diameter of about 20A is connected to the plumbing fixture, and there is no gradient to the floor. This is connected to the merging section without joining on the way. The junction is formed at a position lower than the floor (floor) where the watering device is located (preferably down the first floor), and siphon force is generated by the amount of the head (head) Hs. There is no air in the pipe, and the drainage is drained in a full flow.

このサイフォン排水方法では横引き管に勾配をつけないため床下空間に余裕がもてるが、横引き管が長い場合(後述するL0 )にはサイフォン開始時間が長くかかる。このため、器具によっては排水があふれ出てしまうため施工できない物件もあった。即ち、サイフォン排水方法では、設計可能領域内でのみの設計であり、特に横引き管の長さに限界があった。   In this siphon drainage method, since the horizontal pipe is not inclined, there is room in the underfloor space. However, when the horizontal pipe is long (L0 described later), the siphon start time is long. For this reason, some equipment cannot be constructed because the drainage overflows. In other words, the siphon drainage method is designed only within the designable region, and the length of the horizontal pulling tube is particularly limited.

しかし、近年のマンションでは、間取りの自由度や高級指向等から、水回りを他のフロアとは異なり、南側にもってくることが好まれ、立て管から水回りまでの横引き管の長さが長い物件が増えている。しかるに、横引き管の長さに限界がある勾配排水方法もサイフォン排水方法もこれに十分対応できるものではなかった。逆に言えば、排水に関してはその横引き管の制約範囲内に排水立て管がなければならないということになっており、水回りの設計において大きな制約条件となり、水回り設計の自由度が少なかった。   However, in recent condominiums, it is preferable to bring the water to the south, unlike other floors, due to the degree of freedom in floor plan and luxury orientation, and the length of the horizontal pipe from the vertical pipe to the water is long. Long property is increasing. However, neither the gradient drainage method or the siphon drainage method, which has a limit in the length of the horizontal pipe, can cope with this. Conversely, with regard to drainage, it is supposed that the drainage standpipe must be within the restriction range of the horizontal pulling pipe, which is a major constraint in the design of the water supply, and the degree of freedom of the water supply design was small .

本発明は以上の従来の技術に鑑みてなされたものであり、立て管から水回りまでの横引き管の長さが長い場合でも配管が可能なサイフォン排水方法を提供するものである。   The present invention has been made in view of the above-described conventional technology, and provides a siphon draining method capable of piping even when the length of a horizontal pulling pipe from a vertical pipe to a water pipe is long.

本発明の要旨は、サイフォン排水方法の改良に係り、水回り器具からの横引き管を任意の位置(Lh:L0 >Lh)で階下へ垂下させ、サイフォン排水に必要な水頭を確保し、当該垂下先端を階下の勾配排水管に接続することを特徴とする排水配管方法に係るものである。   The gist of the present invention relates to the improvement of the siphon drainage method, where the horizontal pulling pipe from the watering device is suspended down at an arbitrary position (Lh: L0> Lh) to secure the water head necessary for siphon drainage. The present invention relates to a drainage piping method characterized in that a drooping tip is connected to a downstairs gradient drainage pipe.

本発明のサイフォン排水方法は、立て管から水回りまでの横引き管の長さが長い場合でも配管が可能な排水配管方法を提供するものであり、特に言えば、リフォーム時における水回り位置の変更や増設に極めて簡単に対処できたものである。   The siphon drainage method of the present invention provides a drainage piping method that enables piping even when the length of the horizontal pulling pipe from the vertical pipe to the water circumference is long. It was very easy to deal with changes and expansions.

サイフォン排水方法では横引き管に勾配をつけないため床下空間に余裕がもてるが、横引き管が長い場合にはサイフォン開始時間が長くかかってしまう。このため、排水があふれ出てしまう場合もあるため、施工できない物件もあった。即ち、サイフォン排水方法では、設計可能領域内でのみの設計であり、特に横引き管の長さに限界があった。   In the siphon drainage method, since the horizontal pipe is not inclined, there is room in the underfloor space. However, if the horizontal pipe is long, the siphon start time is long. For this reason, there is a case where construction cannot be performed because drainage may overflow. In other words, the siphon drainage method is designed only within the designable region, and the length of the horizontal pulling tube is particularly limited.

本発明は予定される排水量とサイフォン開始時間との関係上、横引き管の長さを全て無勾配に配管するのではなく、適度な長さに横引きした後に階下に向けて垂下させるものであり、この垂下させた管の先端まで階下に備えた勾配をもって備えられた排水管を設置するという排水方法である。この垂下させた落差がサイフォン水頭Hsとなるものである。尚、本発明にあって、横引き管を垂下させるが、必ずしも垂直に下げる必要はなく、階下に向けて傾斜配置させてもよいことは言うまでもない。   In the present invention, due to the relationship between the planned amount of drainage and the siphon start time, the length of the horizontal pulling pipe is not piped in a non-gradient manner, but is drawn down to the downstairs after being horizontally pulled to an appropriate length. There is a drainage method in which a drain pipe provided with a gradient provided downstairs is installed up to the tip of the suspended pipe. This dropped head becomes the siphon head Hs. In the present invention, the horizontal pipe is suspended, but it is not always necessary to lower it vertically, and it goes without saying that it may be inclined toward the downstairs.

階下の排水管側から見れば、サイフォン力をもたらすために垂下された管の先端に対し、かかる管からの排水を受けに配管されるものであり、垂下させるスペースとしては、例えば壁内、壁間、収納スペース、パイプシャフトスペース(PS)等で階下へ垂下させ、必要な水頭を確保し、その端部は階下の排水管が排水を受けにくることで問題点を解決したものである。   When viewed from the drainage pipe side of the downstairs, the pipe that is drooped to receive the drainage from the pipe to the tip of the pipe that is drooped in order to bring siphon force. In the meantime, the storage space, pipe shaft space (PS), etc. are used to hang down to secure the necessary head, and the end of the drainage pipe of the downstairs makes it difficult to receive drainage.

尚、階下の勾配排水管は、当該階の水回り器具排水に用いられており、或いは排水に用いられていない新設の排水管であって、後者の場合の適用形態としては、リフォームによって水回り器具の位置を変更したり、増設したしする際に、合流継手に新たな排水管を繋ぎ、これをもって適用する場合に特に効果的である。更に、かかる階下の排水管には複数の垂下されたサイフォン排水管を繋いでもよいことは勿論である。   The downstairs slope drain pipe is a new drain pipe that is used for drainage of drainage equipment on the floor, or is not used for drainage. This is particularly effective when a new drainage pipe is connected to the junction joint when the position of the appliance is changed or expanded. Furthermore, it goes without saying that a plurality of suspended siphon drainage pipes may be connected to such a downstairs drainage pipe.

以下、実施例をもって本発明を更に詳細に説明する。図1は本発明の排水方法の概念図であり、例えば4階にサイフォン排水システムを適用した例である。符号1は排水立て管、2は3階に備えられた合流継手、3は水回り器具としてのユニットバスを示す。   Hereinafter, the present invention will be described in more detail with reference to examples. FIG. 1 is a conceptual diagram of the drainage method of the present invention, for example, an example in which a siphon drainage system is applied to the fourth floor. Reference numeral 1 denotes a drainage stack, 2 denotes a confluence joint provided on the third floor, and 3 denotes a unit bath as a watering device.

上記の4階にあって、ユニットバス3のトラップより細径(例えば20A)のポリブテン管6が無勾配をもって敷設され、このポリブテン管6はそのままPS内を通って階下に垂下させたものである。そして、ポリブテン管6はその横引き長さはさほど長いものではなく、これがそのまま3階に向けて垂下させたため、水頭Hsにより横引き管6内の水にサイフォン力が作用し、洗い場側にあふれ出ることなく排水ができることとなったものである。   On the fourth floor, a polybutene pipe 6 having a smaller diameter (for example, 20A) than the trap of the unit bath 3 is laid with no gradient, and this polybutene pipe 6 is suspended down through the PS as it is. . And the polybutene tube 6 is not so long in the horizontal pulling length, and since it is suspended as it is toward the third floor, the siphon force acts on the water in the horizontal pulling tube 6 by the water head Hs, and overflows to the washing area side. The drainage can be done without going out.

しかるに、今までのサイフォン排水工法をそのまま採用した場合には、横引き管6は排水立て管1のPSにまで床面に添って敷設されるために、横引き長さが長くなり、これによってサイフォン開始時間が遅れ、その間に洗い場側に排水があふれ出してしまうケースがあったが、本発明は、横引き管6の横引き長さを短くして階下に垂下させたものであり、その分、これを階下における勾配を付した横引き管10(通常は管径が50A)にて排水を迎え受けることとしたものであり、サイフォン開始時間の遅れがなく排水があふれ出るという欠点を解消したものである。   However, when the conventional siphon drainage method is adopted as it is, the horizontal pulling pipe 6 is laid along the floor surface to the PS of the drainage stack 1, so that the horizontal pulling length becomes long. There was a case where the siphon start time was delayed and the drainage overflowed to the washing area during that time, but the present invention is such that the horizontal pulling length of the horizontal pulling tube 6 is shortened and suspended downstairs, This is because the drainage is received by the horizontal pulling pipe 10 (normally the pipe diameter is 50A) with a slope in the downstairs, eliminating the shortage of siphon start time and overflowing the drainage. It is a thing.

階下における勾配を付けた横引き管10はそのまま3階に備えられた合流継手2に繋がっており、横引き管10に到達した排水は管10内を満流流れとならず、通常の勾配による流れにて排水されることとなる。好ましくは、かかる管10は既設の配管を用いず、新たに合流継手に接続した管を用いるのがリフォーム等の際には効果的である。   The horizontal pipe 10 with a gradient in the downstairs is connected to the junction joint 2 provided on the third floor as it is, and the drainage that has reached the horizontal pipe 10 does not flow into the full flow in the pipe 10, but due to a normal gradient. It will be drained by the flow. Preferably, such a pipe 10 is effective in the case of renovation or the like, without using an existing pipe and using a pipe newly connected to a merging joint.

今まで横引き管の長さが長くてサイフォン排水が敷設できなかった間取りにおいてもサイフォン排水施工ができ、排水管敷設の点では水回り器具のレイアウトが自由に設計できることとなったものである。そして、特にリフォーム時の水回り設計が極めて自由となったものであり、既存のシステムをそのままにして配管施工できる等その効果は大きいものである。   Siphon drainage can be constructed even in a floor plan where siphon drainage could not be laid due to the length of the horizontal pulling tube so far, and the layout of the watering device can be freely designed in terms of laying the drain pipe. In particular, the water design at the time of renovation has become extremely free, and the effect can be great, for example, piping can be carried out without changing the existing system.
