Description
本発明は、耐火二層管と可撓性管の接続構造に関するものである。 The present invention relates to a connection structure between a fireproof double-layer tube and a flexible tube.
従来、耐火二層管の接続構造において、例えば特許文献1に開示されているような環状パッキン材で接続部の隙間を封鎖するようにしている。
しかし、配管業者により先に壁面側等から配管されている耐火二層管に施工誤差が生じているような場合に、便器等を所定位置に設置しようとすると、施工誤差を吸収させるためにゴムジョイント等の可撓性管で両者間を連結する必要があるが、そのような耐火二層管と可撓性管との接続部を封鎖するような目地材は何ら用意されておらず、耐火二層管と可撓性管の接続部の遮煙が良好に行われないという問題点があった。 However, if there is a construction error in a fireproof double-layer pipe previously piped from the wall surface etc. by the plumbing contractor, if you try to install a toilet etc. in a predetermined position, rubber will be used to absorb the construction error. It is necessary to connect the two with a flexible pipe such as a joint, but there is no joint material that seals the connection between such a fire-resistant double-layer pipe and the flexible pipe. There was a problem that smoke shielding at the connecting portion of the two-layer tube and the flexible tube was not performed well.
本発明は上記従来の問題点に鑑み案出したものであって、耐火二層管と可撓性管の接続部分を確実に塞ぐことができて、耐火二層管を通って煙が外へ出るのを良好に防ぐことのできる耐火二層管と可撓性管の接続構造を提供するものであり、その請求項1は、内管と該内管の外周に被覆された外管とで構成される耐火二層管と、可撓性管の接続構造であって、該可撓性管は、本体部と、該本体部に連続して設けられた内管接続部と、該内管接続部に連続して設けられた外管接続部とを備え、前記内管の外周に前記内管接続部がほぼ密着状に被さり、前記外管の外周に前記外管接続部がほぼ密着状に被さることである。 The present invention has been devised in view of the above-described conventional problems, and can reliably block the connection portion between the fireproof double-layer tube and the flexible tube, and the smoke can pass through the fireproof double-layer tube. The present invention provides a connection structure between a fireproof double-layered tube and a flexible tube that can be prevented well from coming out, and the claim 1 includes an inner tube and an outer tube coated on the outer periphery of the inner tube. A fire-resistant double-layer tube and a flexible tube connection structure, wherein the flexible tube includes a main body portion, an inner tube connection portion provided continuously to the main body portion, and the inner tube. An outer tube connecting portion provided continuously to the connecting portion, the inner tube connecting portion covering the outer periphery of the inner tube in a substantially close contact state, and the outer tube connecting portion being substantially in a close contact state with the outer periphery of the outer tube It is to put on.
また請求項2は、前記耐火二層管に接続された可撓性管の接続端部外周に、緊結バンドを締め付け、該緊結バンドで可撓性管の接続端部を耐火二層管に緊結したことである。 According to a second aspect of the present invention, a fastening band is fastened to the outer periphery of the connecting end of the flexible tube connected to the fireproof double-layer tube, and the connecting end of the flexible tube is fastened to the fireproof double-layered tube with the tightening band. It is that.
本発明は、耐火二層管と可撓性管の接続構造であって、可撓性管は、本体部と内管接続部と外管接続部とを備え、耐火二層管の内管の外周に内管接続部がほぼ密着状に被さり、耐火二層管の外管の外周に外管接続部がほぼ密着状に被さることにより、耐火二層管に対し可撓性管を接続することで、耐火二層管の内管と外管を可撓性管で覆うことができ、耐火二層管を通る煙が外へ出るのを良好に防ぐことができ、接続部にテープ等を巻くことなく容易に接続作業を行え、また可撓性管を介して便器等に接続して耐火二層管の施工誤差を良好に吸収させることができ、施工品質のばらつきを少なくすることができるものとなる。 The present invention is a connection structure of a fireproof double-layer tube and a flexible tube, and the flexible tube includes a main body portion, an inner tube connection portion, and an outer tube connection portion. The flexible pipe is connected to the fireproof double-layer pipe by covering the outer pipe with the inner pipe connection part almost in close contact and the outer pipe connection part covering the outer periphery of the outer pipe of the fireproof double layer pipe almost in close contact. So, the inner and outer tubes of the fireproof double-layer tube can be covered with a flexible tube, and the smoke passing through the fireproof double-layer tube can be well prevented from escaping, and a tape or the like is wound around the connection portion. It can be connected easily without any trouble, and it can be connected to a toilet etc. via a flexible tube to absorb construction errors of the fireproof double-layered tube well and to reduce variations in construction quality. It becomes.
また、耐火二層管に接続された可撓性管の接続端部外周に、緊結バンドを締め付け、緊結バンドで可撓性管の接続端部を耐火二層管に緊結したことにより、緊結バンドを締め付けて耐火二層管に可撓性管の接続端部を強固に密着状態にすることができ、耐火二層管を通る煙が外に出るのをより確実に防ぐことができる。 In addition, the fastening band is tightened on the outer periphery of the connection end of the flexible tube connected to the fireproof double-layer tube, and the connection end of the flexible tube is fastened to the fireproof double-layer tube with the tightening band. The connection end of the flexible tube can be firmly brought into close contact with the fireproof double-layer tube, and the smoke passing through the fireproof double-layer tube can be prevented more reliably.
以下、本発明の実施例を図面に基づいて説明する。
図1は、耐火二層管と便器間を、L状の可撓性管で繋いで、施工誤差を吸収しつつ連結した外観斜視図である。
また図2は、直管状の可撓性管により、耐火二層管と便器の排水管を接続した断面構成図である。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an external perspective view in which a refractory double-layer pipe and a toilet bowl are connected by an L-shaped flexible pipe and connected while absorbing construction errors.
Moreover, FIG. 2 is a cross-sectional block diagram which connected the fireproof two-layer pipe and the drainage pipe of the toilet bowl by the straight tubular flexible pipe.
このように、場面に応じて、L状の可撓性管3A又は直管状の可撓性管3Bの何れかを用いて、耐火二層管2と便器1を連結することができるものである。
即ち、配管業者等により、壁面等からトイレ内に配管施工されている耐火二層管2に対し、トイレ内の所定位置に便器1を設置する際に、耐火二層管2の施工誤差を良好に可撓性管3A又は3Bで吸収させて、施工品質のばらつきを少なくすることができるものである。

The
また、本体部4から内管接続部6の内周に至る部分には、軸方向に対し直角に当接段部4aが形成されており、この当接段部4aが耐火二層管2の内管2aの先端に当接されるように構成されている。
Further, a
このように、内管接続部6と外管接続部7が予め一体形成されている可撓性管3A又は3Bを用いて、耐火二層管2の内管2aの外周に内管接続部6を、外管2bの外周に外管接続部7を押し込んで覆設させて、容易に可撓性管の接続端部5を耐火二層管2の端部に接続することができ、その状態では、内管接続部6の内周が内管2aの外周にほぼ密着状となり、また外管接続部7の内周が外管2bの外周にほぼ密着状となる。
Thus, the inner
また、可撓性管3A,3Bの本体部4の他端側には、便器1の排水管1aの外周に密着状に嵌め込まれる排水管接続部8が一体形成されており、排水管接続部8を排水管1aに差し込み状に容易に接続することができるものである。
In addition, a drain
なお、この排水管接続部8の外周には、バンド溝8aが凹み状に形成されており、このバンド溝8a内に緊結バンド11を外側から締め付けて、強固に排水管1aの外周に排水管接続部8を密着固定させることができるものである。
また同様に、内管接続部6の外周には、凹み状にバンド溝6aが形成され、また外管接続部7の外周にも凹み状にバンド溝7aが形成されており、それぞれバンド溝6a内には外側から緊結バンド9を締め付け、バンド溝7a内には緊結バンド10を締め付けて、緊結バンド9を締め付けることにより、内管接続部6を内管2aの外周に強固に密着させることができ、また緊結バンド10を締め付けることにより、外管接続部7を外管2bの外周に強固に密着させることができるものであり、このように緊結バンド9,10を用いることで、可撓性管3A,3Bが外れることがなく、密着状態が強力なものとなって、耐火二層管2の隙間S内を通る煙が接続目地部Mから外へ出てくるのを確実に防ぐことができ、耐火性が向上したものとなる。
