Abstract
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を行う際に、建物の外側に設けた仮設配管路の縦配管路と建物内の各住戸のメーターボックス内又はパイプスペース内に設置されて水道メーターを装着したメーターユニットとを接続する給水用吊下げ配管に係り、特に、建物の外廊下の天井面及び外廊下の壁面に沿って配設される給水用吊下げ配管に関するものである。 The present invention is intended for the outside of a building when renewing or repairing a water supply pipeline (water supply pipeline) laid in a multi-storey building such as a condominium, a school, a hospital, or a building. Related to the water supply suspension pipe that connects the vertical pipe line of the temporary pipe line installed in the building and the meter unit equipped with the water meter installed in the meter box or pipe space of each dwelling unit in the building, especially in the building The present invention relates to a water supply suspension pipe arranged along a ceiling surface of an outer corridor and a wall surface of the outer corridor.
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, water supply pipes laid in multi-storey buildings such as apartments, schools, hospitals, buildings, etc., have been generated in water supply pipes such as galvanized steel pipes when they have been used for many years. Rust etc. causes outflow of red water, slimy inside the pipe, generation of bacteria, decrease in flow rate and water pressure, generation of scale, outflow of scale, etc., resulting in deterioration of water quality and sanitary problems, and packing Various adverse effects such as water leakage accident due to deterioration will occur.
そのため、集合住宅等の数階建ての建物においては、上述した問題が発生すると、給水配管路の更新工事や補修工事を行っている。このとき、建物内に敷設されている給水配管路の更新工事や補修工事においては、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や補修は許されない。 Therefore, in the case of a multi-storey building such as an apartment house, when the above-mentioned problem occurs, renewal work or repair work of the water supply pipeline is performed. At this time, in the renewal work and repair work of the water supply pipe line laid in the building, due to the resident's life, it is not allowed to renew or repair the water pipe line due to long-term water interruption.
このように、従来の給水配管路の更新工事や補修工事においては、長期間、長時間の断水による管路更新や補修が許されないため、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）。 As described above, in the conventional renewal work or repair work of the water supply pipeline, since it is not allowed to renew or repair the pipeline due to long-term water interruption for a long period of time, a method of providing a so-called temporary pipeline is adopted (for example, , Patent Document 1 and Patent Document 2).
前記仮設配管路には、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。 A vinyl pipe, a polyethylene pipe, or the like, which is lightweight and has excellent handleability, is widely used in the temporary pipe passage instead of a metal pipe such as a steel pipe. In particular, when a temporary pipe line is laid using a vinyl pipe, an adhesive is used to connect the vinyl pipes to each other for permanent bonding.
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 the vinyl pipes are used, there is a problem that not only it takes time to join the vinyl pipes, but also a considerable time is required from the completion of the joining to the start of the 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、配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 pipeline, it is necessary to cut the pipe because it is permanently connected, which consumes time and labor, and since the pipe cannot be reused, the temporary pipe after removal is required. Since it is necessary to scrap all the road forming members, there are many problems in 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２０１２−１２２２０９号公報（特許文献３）として公開している。 On the other hand, the applicant of the present invention has developed a temporary pipeline that solves the above-mentioned problems and has disclosed it as Japanese Patent Laid-Open No. 2012-122209 (Patent Document 3).
即ち、前記各仮設配管路は、図示していないが、ポリエチレン樹脂材により形成した直管、エルボ、チーズ、異径管、伸縮管等の管本体を適宜に突合せ融着すると共に、端部に位置する管本体の開口端部にポリエチレン樹脂製の筒状接続部を突合せ融着して仮設配管ユニットを形成し、当該仮設配管ユニットの筒状接続部同士を対向せしめて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、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気密状に接続することにより形成されている。 That is, each of the temporary pipe lines, although not shown, a straight pipe formed of a polyethylene resin material, an elbow, cheese, a pipe with a different diameter, a tubing body such as a telescopic pipe is butt-welded appropriately, and at the end portion. A polyethylene resin tubular connection portion is butt-fused at the open end of the pipe body to form a temporary piping unit, and the tubular connection portions of the temporary piping unit are made to face each other, and the tip of the tubular connection portion is opposed. The annular collar formed on the outer peripheral surface of the part is covered with an annular packing, and the annular collar and the annular packing are wrapped in a split housing type pipe joint and tightened to fix the temporary piping units to each other. It is formed by connecting in a gastight manner with a packing and a housing type pipe joint.
このように、前記仮設配管路は、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、管継手及び環状のパッキンを外すだけで仮設配管ユニット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。 As described above, since the temporary pipe line is formed by connecting the temporary pipe units to each other in an airtight manner with the annular packing and the housing type pipe joint, the temporary pipe line can be easily formed and the construction period can be improved. The temporary piping unit can be easily separated just by removing the pipe joint and the annular packing, and the temporary pipe unit and the pipe joint are hardly damaged when the temporary pipe passage is disassembled. It has the advantage that it can be reused.
ところで、上述した仮設配管路を用いた給水配管路の更新工事や補修工事においては、集合住宅等の建物に仮設配管路の設置スペースが無い場合、仮設配管路を形成する縦配管路を更新工事や補修工事の期間中だけ建物の外側に設置している。 By the way, in the renewal work and repair work of the water supply pipeline using the above-mentioned temporary pipeline, when there is no installation space for the temporary pipeline in a building such as an apartment house, the vertical pipeline that forms the temporary pipeline is updated. It is installed outside the building only during the period of repair work.
即ち、仮設配管路の縦配管路は、例えば、集合住宅等の建物の外廊下や外階段等に設けた手摺壁や手摺の外側位置に所定の間隔を空けて並列状に複数配設されており、前記各縦配管路と建物内の各住戸のメーターボックス内又はパイプスペース内に設置されている水道メーターを装着したメーターユニットとは、給水ホース等から成る給水用配管で接続されている。尚、縦配管路は、建物の外側に施工する際に、仮設配管ユニット等の落下を防止するため、配管ユニットの一部が建物の各階で外側廊下や外側階段に設けた手摺壁や手摺に固定されている。 That is, the vertical pipelines of the temporary pipelines are, for example, arranged in parallel at predetermined intervals at the outer positions of the handrails and the handrails provided in the outer corridor and the outer stairs of buildings such as apartment houses. The vertical pipes and the meter unit equipped with a water meter installed in the meter box or pipe space of each dwelling unit in the building are connected by a water supply pipe such as a water supply hose. In addition, in order to prevent the temporary piping unit etc. from falling when constructing the vertical piping path on the outside of the building, part of the piping unit is installed on the handrail walls and handrails provided in the outer corridor and outer stairs on each floor of the building. It is fixed.
前記給水用配管は、基本的には住民の通行の邪魔にならないように、また、子供等にイタズラされないように、縦配管路からメーターボックス内又はパイプスペース内まで建物の外廊下の天井面及び外廊下の壁面に沿って吊下げ状態で配設されている。 The water supply pipe basically covers the ceiling surface of the outer corridor of the building from the vertical pipe line to the meter box or pipe space so as not to interfere with the passage of residents and to prevent mischief from children and the like. It is arranged in a suspended state along the wall of the outer corridor.
このとき、給水用配管には、縦配管路とメーターボックス又はパイプスペースとの距離や位置に関係なく、比較的自由に配管することができる可撓性の給水ホースが使用されている。 At this time, as the water supply pipe, a flexible water supply hose that allows relatively free piping regardless of the distance or position between the vertical pipe path and the meter box or pipe space is used.
給水用配管に可撓性の給水ホースを使用すると、前記給水ホースは、剛性がないため、外廊下の天井面に沿って配設する場合には、図１０（Ａ）〜（Ｃ）に示すように、様々な構造の配管用固定金具１００を用いて外廊下の天井面や壁面に固定するようにしている（例えば、特許文献４〜６参照）。 When a flexible water supply hose is used for the water supply pipe, the water supply hose does not have rigidity. Therefore, when the water supply hose is arranged along the ceiling surface of the outer corridor, the water supply hose is shown in FIGS. As described above, the pipe fixing fittings 100 having various structures are used to fix to the ceiling surface or wall surface of the outer corridor (see, for example, Patent Documents 4 to 6).
しかしながら、図１０（Ａ）〜（Ｃ）に示す従来の配管用固定金具１００は、何れも配管用固定金具１００自体を建物の天井面や壁面にアンカーボルトやネジ等を用いて固定するタイプであるため、給水配管路の更新工事や補修工事が終了して縦配管路や給水用配管、配管用固定金具１００を取り除いた際に、建物の天井面や壁面に穴が開いてしまうので、補修工事が必要になり、作業者への負担が増加すると共に、施工時間が長くなると言う問題がある。しかも、電動ドライバー等の電動工具を使用してアンカーボルトやネジ等を外廊下の天井面や壁面に打ち込まなければならないため、作業者の姿勢が不安定になって安全性に劣ることになる。 However, each of the conventional pipe fixing fittings 100 shown in FIGS. 10A to 10C is a type in which the pipe fixing fitting 100 itself is fixed to the ceiling surface or wall surface of the building by using anchor bolts or screws. Therefore, when the vertical pipe line, the water supply pipe, and the pipe fixing bracket 100 are removed after the renewal work and repair work of the water supply pipe line are completed, holes are opened in the ceiling surface or wall surface of the building, so repair work is required. There is a problem that construction is required, the burden on the worker is increased, and the construction time is extended. Moreover, since the anchor bolts, screws, etc. must be driven into the ceiling surface or wall surface of the outer corridor using an electric tool such as an electric screwdriver, the posture of the worker becomes unstable, resulting in poor safety.
また、集合住宅等の建物では、施工後の現状復旧が必要であり、施主側の要求によって外廊下の天井面や壁面にアンカーボルトやネジ等を打ち込めないことがある。 In addition, in buildings such as apartment houses, it is necessary to restore the current state after construction, and anchor bolts or screws may not be driven into the ceiling surface or wall surface of the outer corridor at the request of the owner side.
この場合には、可撓性の給水ホースに替えて剛性を有するビニル管を使用し、ビニル管を外廊下の天井や壁面に沿って配管するようにしている。 In this case, a rigid vinyl tube is used instead of the flexible water supply hose, and the vinyl tube is arranged along the ceiling or wall surface of the outer corridor.
しかし、給水用配管にビニル管を使用すると、接続に接着剤を使用するため、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うえ、給水用配管の撤去時には、配管を切断しなければならず、時間と労費を費やすと言う問題がある。 However, if a vinyl pipe is used for the water supply pipe, an adhesive will be used for the connection, so not only will it take a long time to join, but also it will take a considerable time from the completion of joining to the start of tap water supply, and the water supply pipe When removing, there is a problem that the piping must be cut, which consumes time and labor.
本発明は、このような問題点に鑑みて為されたものであり、その目的は、アンカーボルトやネジ等を建物の外廊下の天井面や壁面に打ち込む必要がなくなると共に、配管の接続に接着剤を使用することがなく、作業負担が少なくなって施工時間の短縮及び安全性の向上を図れると共に、建物への修復作業や復旧作業も無くなって工期の短縮を図れるようにした給水用吊下げ配管を提供することにある。 The present invention has been made in view of the above problems, and an object thereof is to eliminate the need to drive anchor bolts, screws, etc. to the ceiling surface or wall surface of the outer corridor of a building, and to bond pipes. Suspension for water supply that does not use chemicals, reduces the work load, shortens construction time and improves safety, and also shortens the construction period by eliminating repair work and restoration work on the building To provide the plumbing.
