Description

本発明は、マンション等の集合住宅、学校、病院、ビル等の数階建ての建物内に敷設されている給水配管路（上水道管路）の更新工事や補修工事等を行う際に用いられる仮設配管ユニット及びこれを用いた仮設配管路に係り、特に、仮設配管路の縦配管路を形成する仮設配管ユニットに改良を加えることによって、仮設配管路を簡単且つ迅速に形成することができて工期の大幅な短縮を図れ、給水配管路の更新工事や補修工事の際に発生する断水時間を居住者の日常生活に支障のないように極力短くすることができ、また、用済み後には、極めて簡単に仮設配管路を分解できると共に、分解後の仮設配管ユニット等を再利用できるようにした仮設配管ユニット及びこれを用いた仮設配管路に関するものである。 The present invention is a temporary construction used when performing renewal work, repair work, etc. of water supply pipes (water supply pipes) laid in several-story buildings such as apartments, schools, hospitals, and buildings. It is possible to easily and quickly form a temporary piping line by improving the piping unit and the temporary piping unit that forms the vertical piping path of the temporary piping line. The water outage time that occurs during renewal work and repair work of water supply pipes can be shortened as much as possible so as not to interfere with the daily life of residents, and it is extremely short after use. The present invention relates to a temporary piping unit in which a temporary piping line can be easily disassembled and the temporary piping unit after disassembly can be reused, and a temporary piping line using the temporary piping unit.

一般に、マンション等の集合住宅、学校、病院、ビル等の数階建ての建物内に敷設されている給水配管路においては、これを長年使用していると、亜鉛メッキ鋼管等の給水管内に発生した錆等が原因となって赤水の流出、管内のぬめり、バクテリアの発生、流量及び水圧の低下、スケールの発生、スケールの流出等が生じ、水質の悪化や衛生面の問題が生じるうえ、パッキンの劣化による漏水事故等の様々な悪影響が生じて来る。 Generally, in a water supply pipe line laid in a multi-story building such as a condominium, a school, a hospital, a building, etc., if it is used for many years, it will occur in the water supply pipe such as a galvanized steel pipe. Rust caused by red water outflow, slimming in the pipe, bacterial outbreak, decrease in flow rate and water pressure, scale outbreak, scale outflow, etc., resulting in deterioration of water quality, hygiene problems, and packing. Various adverse effects such as water leakage accidents will occur due to deterioration of the building.

特に、マンション等の集合住宅においては、水道事業体（水道局）が給水配管路を直接に管理しておらず、通常は管理会社や集合住宅の所有者にその管理が一任されている。そのため、給水配管路の保守管理が不十分になり勝ちとなり、結果として、経年変化による給水管の老朽化が想定以上に進行しており、安全・安心な水供給の要望に対応するため、多くの給水配管路でその更新が必要となって来ている。 In particular, in condominiums and other condominiums, the water supply entity (Waterworks Bureau) does not directly manage the water supply piping line, and usually the management company or the owner of the condominium is left to manage it. As a result, the maintenance of water supply pipes tends to be inadequate, and as a result, the water supply pipes are aging more than expected due to aging, and many people need to meet the demand for safe and secure water supply. It is becoming necessary to renew the water supply pipe line.

また、安全な水に対する需要の高まりから、集合住宅の給水方法をタンク圧送方式から直圧給水方式へ切替えする必要性が増加して来ており、給水方法の切り替えに起因する給水配管路の更新が増加して来ている。 In addition, due to the increasing demand for safe water, there is an increasing need to switch the water supply method of apartment houses from the tank pumping method to the direct pressure water supply method, and the water supply piping line is updated due to the switching of the water supply method. Is increasing.

ところで、集合住宅等の屋内に敷設されている給水配管路の更新においては、居住民の生活があるため、長期間、長時間の断水による管路更新は許されない。そのため、従来の給水配管路の更新工事においては、所謂仮設配管路を設ける工法が採用されている（例えば、特許文献１及び特許文献２参照）。 By the way, in the renewal of water supply pipes laid indoors such as apartment houses, it is not allowed to renew the pipes due to long-term water outage due to the lives of residents. Therefore, in the conventional renewal work of the water supply pipe line, a method of providing a so-called temporary pipe line is adopted (see, for example, Patent Document 1 and Patent Document 2).

一般に、給水配管路の更新工事に於ける仮設配管路では、鋼管等の金属管に代えて軽量で取扱性に優れたビニル管やポリエチレン管等が広く使用されている。特に、ビニル管を用いて仮設配管路を敷設する場合には、ビニル管同士の接続に接着剤を使用し、永久的な結合を行っている。 In general, in temporary pipe lines for renewal work of water supply pipe lines, vinyl pipes, polyethylene pipes, etc., which are lightweight and have excellent handleability, are widely used instead of metal pipes such as steel pipes. In particular, when a temporary piping path is laid using vinyl pipes, an adhesive is used to connect the vinyl pipes to each other for permanent connection.

しかし、ビニル管を用いた場合、ビニル管同士の接合に時間が掛かるだけでなく、接合完了から水道水の供給開始までに相当の時間を要するという問題があった。 However, when vinyl pipes are used, there is a problem that not only it takes time to join the vinyl pipes to each other, but also it takes a considerable amount of time from the completion of joining to the start of supply of tap water.

また、仮設配管路の撤去には、永久的な結合を行っているために配管を切断しなければならず、時間と労費を費やすうえ、管の再利用が出来ないために撤去後に仮設配管路の形成部材を全てスクラップ処分する必要があり、省資源や環境保全を図る上で多くの問題を抱えている。 In addition, when removing the temporary pipe line, the pipe must be cut because it is permanently connected, which consumes time and labor and cannot be reused, so the temporary pipe is removed after the removal. It is necessary to dispose of all the road forming members as scrap, which poses many problems in terms of resource saving and environmental conservation.

一方、本件出願人は、上述した問題を解決する仮設配管路を開発し、特開２００３−０９７７６６号公報（特許文献３）、特開２００４−１００７７４号公報（特許文献４）及び特開２０１２−１２２２０９号公報（特許文献５）として公開している。 On the other hand, the applicant has developed a temporary piping line that solves the above-mentioned problems, and has developed Japanese Patent Application Laid-Open No. 2003-0976766 (Patent Document 3), Japanese Patent Application Laid-Open No. 2004-1000774 (Patent Document 4), and Japanese Patent Application Laid-Open No. 2012-. It is published as Gazette No. 122209 (Patent Document 5).

即ち、前記各仮設配管路は、図示していないが、何れもポリエチレン樹脂製の管本体（直管、エルボ、チーズ、異径管、伸縮管等）の両端部又は複数の管本体を接続して形成した仮設配管ユニットの両端部に、それぞれポリエチレン樹脂製の筒状接続部を突合せ融着により接続し、接続する管本体又は仮設配管ユニットの筒状接続部を対向せしめると共に、対向せしめた筒状接続部の先端部外周面に形成した環状の鍔部に環状のパッキンを被せ、前記環状の鍔部及び環状のパッキンを二つ割り状のハウジング形の管継手で抱き込んで締め付け固定し、管本体同士又は仮設配管ユニット同士等を環状のパッキン及びハウジング形の管継手で気密状に接続することにより形成されている。 That is, although each of the temporary piping lines is not shown, both ends of a pipe body made of polyethylene resin (straight pipe, elbow, cheese, different diameter pipe, expansion pipe, etc.) or a plurality of pipe bodies are connected. Cylindrical connection parts made of polyethylene resin are connected to both ends of the temporary piping unit formed by butt fusion, and the pipe body to be connected or the tubular connection part of the temporary piping unit is made to face each other, and the pipes are made to face each other. An annular packing is placed on the annular flange formed on the outer peripheral surface of the tip of the shape connection portion, and the annular flange and the annular packing are embraced and fixed by a halved housing-shaped pipe joint to tighten and fix the pipe body. It is formed by airtightly connecting each other or temporary piping units with an annular packing and a housing-type pipe joint.

このように、前記仮設配管路は、管本体同士又は仮設配管ユニット同士等をパッキン及び管継手で気密状に接続することにより形成されるため、仮設配管路を簡単に形成することができて工期の短縮を図れると共に、管継手を外すだけで管本体を簡単に分離することができ、また、仮設配管路の分解時に管本体や仮設配管ユニット、管継手が損傷することが殆どなく、再利用できると言う利点がある。 In this way, the temporary piping line is formed by airtightly connecting the pipe bodies or the temporary piping units with packings and pipe joints, so that the temporary piping line can be easily formed and the construction period. The pipe body can be easily separated by simply removing the pipe joint, and the pipe body, temporary piping unit, and pipe joint are hardly damaged when the temporary pipe path is disassembled, and can be reused. There is an advantage that it can be done.

しかしながら、前記仮設配管路においても、未だ解決すべき問題点が残されている。 However, even in the temporary piping line, there are still problems to be solved.

即ち、前記仮設配管路においては、管本体同士又は仮設配管ユニット同士を接続する際に予め環状のパッキンを管本体や仮設配管ユニットに嵌めておき、環状のパッキンを突き合せた筒状接続部の両鍔部に均等に被せ、環状のパッキンの幅方向中心位置を突き合せた筒状接続部の鍔部の突き合せ面に合わさなければならないため、管本体や仮設配管ユニットの接続作業に意外と時間が掛ってしまうと言う問題があった。しかも、環状のパッキンの内径が筒状接続部の鍔部の外径よりも小径に形成されているため、パッキンを伸ばして拡げた状態で上述した作業を行わなければならず、管本体や仮設配管ユニットの接続作業により一層時間が掛ることになる。 That is, in the temporary piping path, when connecting the pipe bodies or the temporary piping units to each other, an annular packing is previously fitted to the pipe body or the temporary piping unit, and the annular packing is abutted against the tubular connection portion. Since it is necessary to cover both flanges evenly and align the center position of the annular packing in the width direction with the butt surface of the flange of the tubular connection, it takes a surprising amount of time to connect the pipe body and the temporary piping unit. There was a problem that it would take. Moreover, since the inner diameter of the annular packing is formed to be smaller than the outer diameter of the flange portion of the tubular connection portion, the above-mentioned work must be performed with the packing extended and expanded, and the pipe body or temporary installation must be performed. It will take more time to connect the piping unit.

また、前記仮設配管路においては、管本体同士又は仮設配管ユニット同志をパッキン及び管継手で接続したときにパッキンが管継手に噛み込むことがあり、パッキンのシール性が損なわれて漏水すると言う問題もある。 Further, in the temporary piping path, when the pipe bodies or the temporary piping units are connected to each other by the packing and the pipe joint, the packing may bite into the pipe joint, and the sealing property of the packing is impaired to cause water leakage. There is also.

更に、前記仮設配管路においては、筒状接続部の鍔部が管本体の外周面よりも外方へ出っ張っているため、管本体の取り扱い中において鍔部の外周面に傷や小さな異物（埃や砂、ゴミ等）が極めて付き易く、鍔部に傷や異物が付着した場合には、鍔部の外周面にパッキンを被せてシールしても、シール性が大いに損なわれると言う問題がある。 Further, in the temporary piping path, since the flange portion of the tubular connection portion protrudes outward from the outer peripheral surface of the pipe body, scratches and small foreign matter (dust) on the outer peripheral surface of the flange portion during handling of the pipe body. , Sand, dust, etc.) is extremely easy to adhere to, and if scratches or foreign matter adhere to the collar, even if the outer peripheral surface of the collar is covered with packing to seal it, there is a problem that the sealing performance is greatly impaired. ..

本発明によれば、合成樹脂製の直線状の管本体やチーズ等を直列状に接続して成る仮設配管ユニットの一端部に受け口を設けると共に、仮設配管ユニットの他端部に挿し口を設けているため、仮設配管ユニットの受け口に他の仮設配管ユニットの挿し口を、また、仮設配管ユニットの挿し口に更に他の仮設配管ユニットの受け口をそれぞれ挿し込み、受け口及び挿し口にハウジング形の管継手を装着するだけで、仮設配管ユニットを直列状に順次接続することができる。その結果、本発明によれば、従来のように管本体同士又は仮設配管ユニット同士を環状のパッキン及びハウジング形の管継手で接続するようにした仮設配管路に比較して仮設配管路の縦配管路を簡単且つ迅速に形成できて高能率で建物に敷設することができ、工期の短縮及びコストの低減を図れる。 According to the present invention, a receiving port is provided at one end of a temporary piping unit formed by connecting a straight pipe body made of synthetic resin, cheese, etc. in series, and an insertion port is provided at the other end of the temporary piping unit. Therefore, the insertion port of another temporary piping unit is inserted into the receiving port of the temporary piping unit, and the receiving port of another temporary piping unit is further inserted into the insertion port of the temporary piping unit, and the receiving port and the insertion port are of the housing type. Temporary piping units can be connected in series in sequence simply by installing a pipe joint. As a result, according to the present invention, the vertical piping of the temporary piping path is compared with the conventional temporary piping path in which the pipe bodies or the temporary piping units are connected to each other by an annular packing and a housing type pipe joint. Roads can be formed easily and quickly, and can be laid in buildings with high efficiency, shortening the construction period and reducing costs.

また、本発明によれば、仮設配管ユニットの長さが、建物の階高に合わせた長さに設定されているため、仮設配管ユニットを建物の各階に一つずつ確実に配置することができ、仮設配管ユニットの分岐口と各住戸の水道メーター又はメーターユニットとの接続を行い易くなる。 Further, according to the present invention, since the length of the temporary piping unit is set to the length according to the floor height of the building, one temporary piping unit can be reliably arranged on each floor of the building. , It becomes easy to connect the branch port of the temporary piping unit to the water meter or meter unit of each dwelling unit.

更に、本発明によれば、仮設配管ユニットの受け口の先端部に形成した受け筒部の内周面又は仮設配管ユニットの挿し口の先端部に形成した挿し筒部の外周面の何れか一方に、環状のＯリング溝を一つ又複数列形成し、前記Ｏリング溝にシール用のＯリングを嵌め込み、受け口と挿し口との間をＯリングによりシールするようにしているため、従来の仮設配管路のように環状のパッキンが管継手に噛み込んでパッキンのシール性が損なわれると言うことがなく、シール性に優れたものとなる。特に、Ｏリング溝を複数列形成し、各Ｏリング溝にＯリングを嵌め込んだ場合には、より一層シール性に優れたものとなる。また、挿し筒部の外周面にＯリングを装着している場合には、環状の鍔部の方が挿し筒部の外周面よりも外方へ出っ張っているので、仮設配管ユニットの取り扱い中において挿し筒部の外周面及びＯリングに傷や異物が極めて付き難くなり、シール性が損なわれるのを防止することができる。更に、受け筒部の内周面にＯリングを装着している場合には、Ｏリングに傷や異物がより一層付き難くなる。 Further, according to the present invention, on either the inner peripheral surface of the receiving cylinder portion formed at the tip end portion of the receiving port of the temporary piping unit or the outer peripheral surface of the inserting cylinder portion formed at the tip end portion of the insertion port of the temporary piping unit. , One or more rows of annular O-ring grooves are formed, the O-ring for sealing is fitted into the O-ring groove, and the space between the receiving port and the insertion port is sealed by the O-ring. Unlike the piping path, the annular packing does not bite into the pipe joint and the sealing property of the packing is not impaired, and the sealing property is excellent. In particular, when a plurality of rows of O-ring grooves are formed and the O-rings are fitted into the O-ring grooves, the sealing property is further improved. Further, when the O-ring is attached to the outer peripheral surface of the insertion cylinder portion, the annular flange portion protrudes outward from the outer peripheral surface of the insertion cylinder portion, so that during handling of the temporary piping unit. It is possible to prevent scratches and foreign matter from being attached to the outer peripheral surface of the insertion cylinder portion and the O-ring, and to prevent the sealing property from being impaired. Further, when the O-ring is attached to the inner peripheral surface of the receiving cylinder portion, it becomes more difficult for the O-ring to be scratched or foreign matter is attached.
