Description

本発明は排水装置の各部材の接続に使用される接合部材に関する。 The present invention relates to a joining member used for connecting each member of a drainage device.

通常、排水装置に関する部材同士の接続には、接合部材として主に内部にネジ部を設けたナットが使用される。ナット内部のネジ部に対して相手側の部材に設けられたネジ部を螺合させることにより、部材同士を接続させることができる。このナットを用いた接続構造においては、ナットを一方の部材に何らかの形で固定／取り付けする必要のある場合が多い。例えば特開平７−７１０６１号の図７、図８（本文中段落００１５乃至段落００１６）の実施例では、インナー（本文中では「連結管３５」）と呼ばれるフランジ部（本文中では「固定片３６」）を有したパーツを用いて取り付けを行う。具体的には、ナットをインナーと管体（本文中では「上半体１１」）とで挟み込んだ状態にしつつ、管体の一端に接着剤を塗布して接着し、管体にインナーを取り付けている。
このようにすることで、相手側の部材（本文中では「排水管４」）のネジ部に、ナットに設けられたネジ部を締め付けたとき、「相手側の部材−相手側の部材のネジ部−ナット−管体」と接続が行われ、取り付けを行うことができる。
特開平７−７１０６１号公報 Usually, a nut having a threaded portion inside is mainly used as a joining member for connecting members related to the drainage device. The members can be connected to each other by screwing the threaded portion provided on the mating member with the threaded portion inside the nut. In the connection structure using this nut, it is often necessary to fix / attach the nut to one member in some form. For example, in the embodiment shown in FIGS. 7 and 8 (paragraphs 0015 to 0016 in the text) of Japanese Patent Laid-Open No. 7-71061, a flange portion (in the text, “fixing piece 36”) called an inner (“connecting pipe 35” in the text) is used. ”) Is used for attachment. Specifically, while the nut is sandwiched between the inner body and the tubular body (in the text, “upper half body 11”), an adhesive is applied and bonded to one end of the tubular body, and the inner body is attached to the tubular body ing.
In this way, when the screw portion provided on the nut is tightened to the screw portion of the mating member (in the text, “drain pipe 4”), “the mating member—the mating member screw” The "part-nut-pipe" is connected and can be attached.
JP-A-7-71061

上記のようにインナーと管体とを接着剤を利用して接着する方法を採用するためには、少なくともインナーと部材とが接着可能な素材であると共に、接着を行うための接着しろを用意する必要がある。
しかし、この接続構造が採用される排水装置の内部を流れる排水は、石鹸・洗剤・有機溶媒などの薬品成分が溶け込んでいる場合が多いため、排水装置にはポリプロピレン樹脂など、薬品の成分に対して溶けるなどの影響が出にくい、薬品への耐性（耐薬性）のある素材がよく利用される。通常の接着剤は即ち薬品で、塗布した素材の表面を溶融させることで接着するものであるため、前述のようなポリプロピレン樹脂など、排水装置に採用される耐薬性のある素材に対して、有効な接着剤が存在しないのが現状である。
また近年、キャビネットではキャビネット内の収納性を向上させるために、床下空間では床上の生活空間を広くする目的から、床下空間を狭くするために、それぞれ配置・配管される排水装置を小型化する傾向にある。このため、排水装置における接着剤を塗布するための接着しろについても、できる限り縮小・省略したい、という要望があった。 In order to adopt the method of bonding the inner and the tubular body using an adhesive as described above, at least the inner and the member are materials that can be bonded, and an adhesive margin for bonding is prepared. There is a need.
However, the drainage that flows inside the drainage system that employs this connection structure often contains chemical components such as soap, detergent, and organic solvent. Materials that are resistant to chemicals such as melting and resistant to chemicals (chemical resistance) are often used. Ordinary adhesives are chemicals, which are bonded by melting the surface of the applied material, so they are effective for chemical resistant materials such as the polypropylene resin described above that are used in drainage equipment. The current situation is that no adhesive is present.
In recent years, in order to improve the storage capacity in the cabinet, in order to widen the living space on the floor in the underfloor space, in order to narrow the underfloor space, the drainage devices arranged and piped tend to be downsized. It is in. For this reason, there has been a demand for reducing and omitting the bonding margin for applying the adhesive in the drainage device as much as possible.

本発明は、上記問題を解決するため、接着剤を用いなくとも接合部材を排水装置に関する部材に簡単に取り付けられる構造とすることによって、排水装置に関する部材に接着剤を使用することが困難な耐薬性等のある素材を用いることができると共に、接着しろを設けず省略することができる接合部材に関する。 In order to solve the above-mentioned problem, the present invention provides a chemical resistant agent in which it is difficult to use an adhesive for a member related to a drainage device by adopting a structure in which a joining member can be easily attached to a member related to a drainage device without using an adhesive. The present invention relates to a joining member that can be omitted without providing an adhesive margin while using a material having properties.
