Description

【０００１】
【発明の属する技術分野】
本発明は、底体および当該底体に着脱可能な蓋体で構成し、複数の配管ダクトの集合部に接続可能な配管ダクト継手に関する。
【０００２】
【従来の技術】
この種の配管ダクト継手では、図８に示すごとく、底体Ｓの側壁部３０となる部分を形成するのに、底体Ｓの一部を折り曲げ、一枚の板部材で側壁部３０を構成するものがあった。図８は、当該配管ダクト継手に対して四つの配管ダクトＤを接続する例である。この従来例の場合には、配管ダクト継手に係るＸ方向における取付部の形状と、Ｙ方向における取付部の形状とが異なっており、配管ダクトＤの取付態様も互いに相違するものとなっていた。
【０００３】
例えば、Ｘ方向から配管ダクトＤを取り付ける場合には、前記側壁部３０の面方向と、配管ダクトＤの面方向とが異なるため、前記側壁部３０に形成したフランジ状の取付部３１に配管ダクトＤのダクト側板２１を重ね合わせ、ねじ部材などを用いて両者を締結する。
【０００４】
一方、Ｙ方向から配管ダクトＤを取り付ける場合には、前記側壁部３０の面方向と、配管ダクトＤのダクト側板２１の面方向とが一致するため、上記のごとくフランジ状の取付部３１を特に設ける必要はない。しかし、この場合には、図８に示すごとく、二枚の連結バンド３２を用いて連結していた。即ち、Ｙ方向から配管ダクトＤを接続する場合には、配管ダクトＤと配管ダクト継手との外形がほぼ同一であるから、美感上、両者を正確に一致させることが望ましい。このため、配管ダクトＤのダクト側板２１およびダクト天板１９と配管ダクト継手の側壁部３０および蓋板３３とに亘って、裏側連結バンド３２ｂと表側連結バンド３２ａとを配置し、これら双方の連結バンド３２ａ，３２ｂを用いて両側板どうしおよび両天板どうしを挟持していた。
【０００５】
また、配管ダクト継手は、単なる板部材で側壁部３０を構成しているに過ぎないから、特に、配管ダクト継手の鉛直方向から何らかの外力が加わった場合には、配管ダクト継手の蓋板３３が窪んだり、前記側壁部３０が挫屈するなど、配管ダクト継手が容易に変形する場合があった。
このような変形を防止するためには、特にＹ方向の開口縁部において変形が生じ難いように対処する必要がある。このような理由からも、上記のごとく、特にＹ方向の接続に際してはバンド部材を用いて各縁部の補強を行っていた。
【０００６】
【発明が解決しようとする課題】
しかし、上記従来の技術のごとく、Ｘ方向における接続要領と、Ｙ方向における接続要領とが異なる場合、特に、Ｙ方向の接続に際しては、上記のごとく、連結バンド３２を用いて配管ダクトＤのダクト天板１９等を挟持する必要があったから、当該接続作業が極めて煩雑なものであった。そればかりでなく、配線等のメンテナンスを行うべく配管ダクト継手の天板を外す場合等にも、当該取り外し作業が繁雑なものとなっていた。
【０００７】
また、折り曲げて形成した側壁部３０の強度を少しでも高めるためには、側壁部３０の幅を大きく設定する必要がある。しかし、その結果、配管ダクト継手のＹ方向に沿うサイズが、敷設する配線・配管１の占有幅と側壁部３０の幅との合計となるから、配管ダクト継手のサイズが配線・配管１に必要なサイズ以上のものとなっていた。このように配管ダクト継手の設置面積が増加し、配管ダクト継手のＸ・Ｙ方向の形状に異方性が生じる結果、配管ダクト継手を設置する個所が制約を受ける場合が生じる等、使用に際しての自由度に劣るものとなっていた。
【０００８】
そこで、本発明においては、上記従来の問題点を解消し、配管ダクトの接続効率を向上すると共に、十分な強度を有する配管ダクト継手を提供することを目的としている。
【０００９】
【課題を解決するための手段】
〔構成１〕
本発明に係る配管ダクト継手は、請求項１に記載したごとく、底体が略矩形状の底板部材を有すると共に、当該底板部材とは別体に構成して蓋体を固定する柱部材を前記底板部材の夫々の隅部に取り付けて構成した点に特徴を有する。
〔作用効果〕
本構成のごとく、底板部材とは別体に構成した柱部材を前記底板部材に取り付ける構成であれば、例えば、任意の断面形状を有する柱部材を用いることが可能となる。断面形状を任意に決定できることとなれば、柱部材の剛性を自由に高めることができ、柱部材の配置スペースを大幅に縮小することができる。
また、剛性を高めて柱部材の幅などを小さくした場合には、配管ダクト継手の内部において、実際に各種配線・配管を敷設するために必要なスペースのみを確保すればよく、従来技術のごとく、折り曲げ部分の幅が配管ダクト継手のサイズを不必要に拡大してしまうという不都合も生じない。よって、コンパクトな配管ダクト継手を形成することができる。
【００１０】
〔構成２〕
本発明に係る配管ダクト継手は、請求項２に記載したごとく、前記柱部材として、二つの板状部によって前記底板部材に直角な方向に延出する稜線を形成するものを用いることができる。
〔作用効果〕
本構成のごとく、二つの板状部によって稜線を形成するような柱部材を用いることとすれば、非常に簡単な構成でありながら、剛性の高い柱部材を得ることができる。例えば、二枚の板部材どうしが直角な面を形成するように両者の縁部を突き合わせ、当該突き合わせ部分を溶接して柱部材を形成したり、単に一枚の板部材を略直角に折り曲げて柱部材を形成することができる。
この結果、当該柱部材に配管ダクトを接続した場合にも、前記柱部材が曲がり変形するなどの不都合を防止することができる。
【００１１】
〔構成３〕
本発明に係る配管ダクト継手は、請求項３に記載したごとく、前記柱部材の夫々に、二方向に突出するダクト取付部を設けて構成することができる。
〔作用効果〕
本構成のごとく、前記柱部材の夫々に、二方向に突出するダクト取付部を設ける場合には、一本の柱部材に対して、二方向から配管ダクトを接続することが可能となる。例えば、前記二方向を直角方向としておき、配管ダクト継手に対して四方向から配管ダクトを接続させることが可能である。この場合には、一本の配管ダクトの双方の側壁部を、これら側壁部が取り付けられる柱部材の取付部に接続することが可能となる。そして、当該接続要領は、四方向からの配管ダクトについて同様に行うことができる。
即ち、本構成であれば、接続する全ての配管ダクトを同じ要領で接続することができるため、従来例で示したごとく、形状の異なる配管ダクトを接続しなければならないという制限を受けることはない。このため、配管ダクト継手の配置に際して、配置方向を考慮する必要がなく、配管ダクト継手の設置作業を効率化することができる。
【００１２】
〔構成４〕
本発明に係る配管ダクト継手は、請求項４に記載したごとく、前記配管ダクトを取り付けるねじ孔を前記ダクト取付部に形成しておいてもよい。
〔作用効果〕
本構成のごとく、前記ダクト取付部にねじ孔を形成するものであれば、当該取付部に対する配管ダクトの取り付け作業を極めて容易かつ迅速に行うことができる。特に、全てのダクト取付部にねじ孔を形成しておけば、バンド部材を用いて接続を行う等の必要性が解消されるため、上記構成３で示した配管ダクト継手に対して、さらに配管ダクトの取り付け作業を簡単且つ迅速なものにすることができる。
【００１３】
〔構成５〕
本発明に係る配管ダクト継手は、請求項５に記載したごとく、前記蓋体が、天板部と四つの側板部とを有するものとして構成することができる。
〔作用効果〕
本構成のごとく、前記蓋体を、天板部と四つの側板部とで構成しておけば、前記蓋体が箱状となるため、蓋体の剛性が極めて向上する。よって、当該蓋体を前記底体に取り付けることで、配管ダクト継手の全体の強度が向上する。この結果、配線・配管の敷設作業を終了した後において、当該配管ダクト継手、或いは、当該配管ダクト継手に接続してある配管ダクトに何らかの外力が作用した場合でも、配管ダクト継手が容易に変形するのを防止することができる。この結果、配管ダクト継手と配管ダクトとの間に隙間が生じるような不都合が生じず、配管ダクト継手の内部に日光が入射したり、雨水が浸入しやすくなるといった不都合が生じるのを有効に防止して、内部の配線・配管等を確実に保護することが可能となる。
【００１４】
〔構成６〕
本発明に係る配管ダクト継手は、請求項６に記載したごとく、前記四つの側板部のうち前記配管ダクトの取付位置に該当する側板部に、前記天板部に対して略平行かつ外方に突出する第１突出部を形成すると共に、前記底板部材の各辺部のうち前記配管ダクトの取付位置に該当する辺部に、当該底板部材と略同一面状に突出する第２突出部を形成しておき、前記配管ダクトを連結する際に、前記第１突出部および前記第２突出部と、前記配管ダクトの側に突出する前記ダクト取付部とが、前記配管ダクトに内挿するよう構成することができる。
〔作用効果〕
本発明の配管ダクト継手に配管ダクトを連結する場合には、ダクト取付部のみを用い、この他の天板部や底板部材を用いた連結は行わない。即ち、本構成の配管ダクト継手では、第１突出部、および、第２突出部、前記ダクト取付部を、前記配管ダクトに内挿させるものであるが、前記第１突出部および前記第２突出部は、配管ダクトを配管ダクト継手に取り付ける際の、或いは、取り付けた後において、主に、ダクト天板およびダクト底板の位置決め手段としての機能を発揮するものである。例えば、配管ダクトを取り付ける際には、第１突出部にダクト天板を当接させることで、ダクト側板とダクト取付部とに設けた取り付け用の孔の位置合せが容易となる。そして、本構成の配管ダクト継手であれば、前述のごとくバンド状の部材等を用いる必要がないため、ダクト側板とダクト取付部との取り付けを極めて迅速に行うことができる。
また、上記のごとくバンド状の部材等を用いる必要がないため、配管ダクトと配管ダクト継手との接続部がすっきりしたものとなり、接続部の外観を向上させることができる。
さらに、配管ダクトを取り付けた後においては、仮にダクト天板に外部から何らかの荷重が作用した場合でも、ダクト天板が窪もうとするのを前記第１突出部が阻止して配管ダクトの変形量を最小限に止め得る等の効果を期待することもできる。
【００１５】
【発明の実施の形態】
（概要）
本発明の配管ダクト継手について、図面を参照しながら説明する。
図１には、本発明に係る配管ダクト継手の外観斜視図を示す。図２には、当該配管ダクト継手の分解斜視図を示す。
本発明に係る配管ダクト継手は、底体Ｓおよび当該底体Ｓに着脱可能な蓋体Ｆで構成する。当該配管ダクト継手に対しては複数の配管ダクトＤを接続可能である。図１には、四本の配管ダクトＤを連結する例を示している。
【００１６】
（底体）
当該底体Ｓは、配管ダクト継手に敷設する各種配線・配管１を受け支持する部分である。図２に示すごとく、前記底体Ｓは、底板部材２と柱部材３とで構成する。
【００１７】
前記底板部材２は、配管ダクト継手の内部に敷設する各種の配線・配管１を受け支持する部分である。本実施形態においては、前記底板部材２は略矩形状の板部材としてある。本構成のごとく、矩形に形成しておけば、最大で四本の配管ダクトＤを接続することができる。また、底板部材２を単なる板状に構成することで、底板部材２の作製が容易となる。
【００１８】
尚、本実施形態では、前記底板部材２を文字通り板状の部材で構成しているが、当該構成に限られるものではない。例えば、前記配管ダクト継手の外部と内部とに亘って配線・配管１を敷設したい場合があり、そのような場合には前記底板部材２に開口部を設けておくことがある。よって、前記底板部材２は、完全な板状の部材に限られるものではなく、例えば、枠体形状のものであってもよい。
【００１９】
前記底板部材２の所定の位置には脚固定用孔部４を設けてある。これは、例えば図６あるいは図７に示すごとく、門形の脚部５を前記底板部材２の裏面にねじ部材等を用いて取り付ける際等に利用する。
【００２０】
本実施形態においては、前記底板部材２とは別体に形成した柱部材３を、前記底板部材２の夫々の隅部に取り付けて底体Ｓを構成している。当該柱部材３は、前記底板部材２の上方に各種配線・配管１を敷設するための空間を確保するためのものであり、かつ、前記蓋体Ｆを接続するための部材である。
【００２１】
本発明の配管ダクト継手では、以上のごとく、柱部材３を底板部材２とは別体に形成するから、任意の強度或いは剛性を有する柱部材３を底板部材２に取り付けることができる。例えば、本実施形態においては、図２および図３に示すごとく、当該柱部材３が、前記底板部材２に直角な方向に延出する稜線６を形成する二つの板状部７を有している。つまり、前記底板部材２と平行な平面における断面形状が、例えばＬ状をなす部材を用いて柱部材３を構成する。
【００２２】
このような断面形状の柱部材３を用いることで、柱部材３の剛性を高めることができ、柱部材３の断面スペースを大幅に縮小することができる。
また、剛性を高めて柱部材３の幅などを小さくした場合には、配管ダクト継手の内部において、実際に各種配線・配管１を敷設するために必要なスペースのみを確保すればよく、従来技術のごとく、折り曲げ部分の幅が配管ダクト継手のサイズを不必要に拡大してしまうという不都合が生じない。よって、コンパクトな配管ダクト継手を形成することができる。
【００２３】
図３には、前記柱部材３の詳細を示す。前記底板部材２が有する平面を基準にした場合に、図３（イ）は、柱部材３の平面図を示しており、同図（ロ）は側面図を、同図（ハ）は裏面図を示している。
当該柱部材３は、二つの板状部７を連接した形状を有する。そしてこれらの連接部は、前記底板部材２に対して直角方向に延出する稜線６を形成する。二つの板状部７は、例えば、折り曲げて構成してもよいし、前記稜線６の位置で溶接して一体化するものであってもよい。折り曲げて構成する場合には、前記稜線６が微視的に見て局面を有することになる。一方、溶接で構成した場合には、前記稜線６をエッジ状に仕上げることができる。何れの方法で構成する場合でも、柱部材３の強度に差は生じないと考えられる。よって、作製上の容易さ、或いは、外観等の事情に応じて適宜選択して柱部材３を形成すればよい。
【００２４】
前記板状部７には、ダクト取付部８を連接してある。本実施形態では、二つの板状部７に、夫々、ダクト取付部８を取り付けてある。即ち、図３（イ）に示すごとく、二つのダクト取付部８は互いに直角をなすよう形成してあり、直角をなす二方向から接続される二つの配管ダクトＤに接続できるように構成してある。
前記ダクト取付部８には、前記配管ダクトＤを連結するためのダクト取付用孔９を二つ設けてある。例えば、当該ダクト取付用孔９と、配管ダクトＤの側に設けた取付け用の孔とにねじ部材を挿通することで配管ダクトＤの連結を行う。
【００２５】
前記ダクト取付用孔９は、本実施形態では単なる開口を形成するものとしている。よって本構成の場合には、後述するごとく、ねじ部材とナット部材とを利用して配管ダクトＤの取付を行う。本構成であれば、ダクト取付部８を極めて容易に構成することができる。
尚、このダクト取付用孔９は、例えばタップ孔として形成しておくこともできる。この場合には、配管ダクトＤのダクト側板２１にねじ部材を貫通させつつ前記ダクト取付用孔９に螺合させるだけでよいから、配管ダクトＤの接合作業が極めて迅速なものとなる。
【００２６】
前記柱部材３の両端部のうち、前記蓋体Ｆを取り付ける側の端部には、蓋体取付部１０を設けてある。図３（イ）および図４に示すごとく、ここでは、前記板状部７の端部を折り曲げて、前記蓋体Ｆの天板部１１の平面に一致させるように蓋体取付面１２を形成している。当該蓋体取付面１２には蓋体Ｆを固定するための蓋体取付用孔１３を形成してあると共に、蓋体取付部１０の裏面にはナット部材１４を溶接してある。これにより、前記蓋体Ｆを前記蓋体取付面１２に載置した後、蓋体Ｆ及び蓋体取付部１０にねじ部材１５を貫通させつつ前記ナット部材１４に螺合して蓋体Ｆを固定する。
【００２７】
前記底板部材２に対する柱部材３の取付けは、本実施形態においてはスポット溶接により行う。図３（ハ）に示すごとく、前記二つの板状部７の下端部を折り曲げて、前記底板部材２に当接させる固定部１６を形成する。当該固定部１６は、前記底板部材２の裏面側から当接させる。よって、前記固定部１６の両面のうち、前記蓋体取付部１０に面した側の面が固定面１７となる。当該固定面１７と前記底板部材２の裏面とを当接させつつスポット溶接を行い、柱部材３を固定する。
【００２８】
このように、スポット溶接により取り付ける手法を用いることとすれば、底板部材２と柱部材３とが実質的に一体化されるから、柱部材３に係る取付けの信頼性を向上させることができる。また、柱部材３の一端側を折り曲げるだけで、スポット溶接に供する部分を形成可能であるから、前記底体Ｓの製造効率を高めることができる。
【００２９】
尚、前記底板部材２に対する柱部材３の取付は、図５に示すごとく、ねじ部材１５ａを用いて行うこともできる。即ち、前記底板部材２の隅部及び前記柱部材３下端部の固定部１６に柱部材取付用孔を形成しておき、ねじ部材１５ａ及びナット部材１４ａを用いて固定することができる。この場合、図５に示すごとく、前記底板部材２の側にナット部材１４ａを溶接しておけば、ねじ部材１５ａの螺合を容易に行うことができる。
【００３０】
本構成であれは、例えば、当該配管ダクト継手を配管敷設現場において組み立てることが可能となる。つまり、現場に搬入するまでは、当該配管ダクト継手は分解された状態にあり、全体の容積が小さいものとなっているため、可搬性に優れた配管ダクト継手を得ることができる。
【００３１】
（蓋体）
前記蓋体Ｆは、底板部材２に各種配線・配管１を敷設したのち、当該敷設部分を覆うためのものである。
図２に示すごとく、本発明に係る蓋体Ｆは、板状の天板部１１と、当該天板部１１の周囲に形成した側板部１８とで構成する。ここでは、平面形状が正方形である天板部１１を示している。勿論、天板部１１の平面形状は正方形に限られるものではなく、矩形状のものであってもよい。
【００３２】
本実施形態では、前記天板部１１と前記側板部１８とは溶接により接続してある。本手法を用いる場合には、曲げ加工用の金型などを作製する必要がなく、製造に供する設備を簡略化して配管ダクト継手の製造コストを低減することができる。
また、天板部１１と側板部１８とを溶接することで、係る溶接部をエッジ状に構成することができる。よって、意匠上においても特有の効果を発揮させることができる。
【００３３】
本実施形態においては、互いに隣接する側板部１８どうしも溶接してある。このように、天板部１１の周囲を側板部１８で連結し、一種の箱形状とすることで、蓋体Ｆの強度を著しく向上させることができる。よって、当該蓋体Ｆを前記底体Ｓに取り付けた場合には、極めて剛性の高い配管ダクト継手を形成することができ、内部の配線・配管１を確実に保護することができる。
【００３４】
（配管ダクトの取付要領）
図６に当該配管ダクト継手に対する配管ダクトＤの取付要領を示す。
まず、前記配管ダクト継手に脚部５を取付け、所定の位置に設置する。当該配管ダクト継手に対して、連結すべき配管ダクトＤを近接させる。このとき、配管ダクト継手部の天板部１１および配管ダクトＤのダクト天板１９は取り外しておく。ダクト底板２０と一対のダクト側板２１とは予め連結しておく。
【００３５】
図２および図６に示すごとく、本実施形態では、前記四つの側板部１８のうち前記配管ダクトＤの取付位置に該当する側板部１８に、前記天板部１１に対して略平行かつ外方に突出する第１突出部２２を形成してある。一方、前記底板部材２の各辺部のうち前記配管ダクトＤの取付位置に該当する辺部には、当該底板部材２と略同一面状に突出する第２突出部２３を形成してある。
【００３６】
配管ダクトＤを配管ダクト継手の一つの側部に近接させる場合には、図７に示すごとく、ダクト底板２０が前記第２突出部２３の下方に位置するように、かつ、柱部材３に形成したダクト取付部８が、前記ダクト側板２１の内側となるように配管ダクトＤと当該配管ダクト継手と位置合わせする。この状態で、両方のダクト側板２１の夫々外方から、連結用のねじ部材２４を当該ダクト側板２１とダクト取付部８とに貫通させ、配管ダクトＤの内部側から前記ねじ部材２４に対してナット部材２５を螺合させる。
尚、当該ナット部材２５は、ダクト側板２１の裏側に予め溶接止めしておくこともできる。その場合には前記ねじ部材２４の取付作業が迅速化される。
【００３７】
このように、本発明の配管ダクト継手に配管ダクトＤを連結する場合には、ダクト取付部８のみを用い、この他の天板部１１や底板部材２を用いた連結は行わない。よって、前記配管ダクトＤの取付作業が極めて簡単であり、配管ダクト継手の設置作業に係る効率を大幅に向上させることができる。
【００３８】
尚、本発明の配管ダクト継手において、前記第１突出部２２および前記第２突出部２３は、配管ダクトＤを配管ダクト継手に取り付ける際の、或いは、取り付けた後において、主に、ダクト天板１９およびダクト底板２０の位置決め手段としての機能を発揮する。
例えば、配管ダクトＤを取り付ける際には、第１突出部２２にダクト天板１９を当接させることで、ダクト側板２１とダクト取付部８とに設けたダクト取付用孔９の位置合せを自動的に行うことができる。
また、配管ダクトＤを取り付けた後においては、仮にダクト天板１９に外部から何らかの荷重が作用した場合でも、ダクト天板１９が窪もうとするのを前記第１突出部２２が阻止するから、配管ダクトＤの変形量を最小限に止めることができる。
【００３９】
（効果）
以上のごとく、本発明の配管ダクト継手を用いる場合には、任意の強度或いは剛性を有する柱部材３を底板部材２に取り付けるものであるから、柱部材３の断面スペースを大幅に縮小することができ、この結果、配管ダクト継手をコンパクトに仕上げることができる。
さらに、柱部材３の強度が向上させた上に、剛性を有する蓋体Ｆを取り付けることで、配管ダクト継手全体の強度が著しく向上する。よって、当該配管ダクト継手に配管ダクトＤを取り付ける際には、ダクト側板２１のみを連結するだけでよい。当該ダクト側板２１の連結は、通常、ねじ止めで済ますことができるため、配管ダクトＤの取付作業効率を大幅に高めることができる。
【００４０】
（別実施形態）
〈１〉上記実施形態では、当該配管ダクト継手に対して四方向から配管ダクトＤを取り付ける例を示したが、勿論、当該配管ダクト継手に接続する配管ダクトＤの数は四本に限られるものではなく、二本或いは三本でもよい。配管ダクトＤを接続しない側面部については、専用の蓋部材を用意して取り付けることとしてもよいし、当初より、開口を有しない側板部１８を溶接しておいてもよい。
このように、当該配管ダクト継手は、複数の配管ダクトＤが集合する位置であれば何れの位置にも取り付けることができる。この結果、各種配線・配管１の敷設経路を決定する際の自由度を高めることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pipe duct joint that includes a bottom body and a lid body that can be attached to and detached from the bottom body, and that can be connected to an assembly of a plurality of pipe ducts.
[0002]
[Prior art]
In this type of pipe duct joint, as shown in FIG. 8, in order to form a portion that becomes the side wall portion 30 of the bottom body S, a part of the bottom body S is bent and the side wall portion 30 is configured by a single plate member. There was something to do. FIG. 8 is an example in which four pipe ducts D are connected to the pipe duct joint. In the case of this conventional example, the shape of the mounting portion in the X direction and the shape of the mounting portion in the Y direction related to the pipe duct joint are different, and the mounting mode of the pipe duct D is also different from each other. .
[0003]
For example, when the piping duct D is attached from the X direction, the surface direction of the side wall portion 30 and the surface direction of the piping duct D are different, so that the piping duct is attached to the flange-like attachment portion 31 formed on the side wall portion 30. The duct side plates 21 of D are overlapped, and both are fastened using a screw member or the like.
[0004]
On the other hand, when the piping duct D is attached from the Y direction, the surface direction of the side wall portion 30 and the surface direction of the duct side plate 21 of the piping duct D coincide with each other. There is no need to provide it. However, in this case, as shown in FIG. 8, the two connecting bands 32 are used for connection. That is, when the pipe duct D is connected from the Y direction, since the outer shapes of the pipe duct D and the pipe duct joint are substantially the same, it is desirable to make them coincide with each other for aesthetic reasons. For this reason, the back side connecting band 32b and the front side connecting band 32a are arranged across the duct side plate 21 and the duct top plate 19 of the pipe duct D, the side wall portion 30 and the cover plate 33 of the pipe duct joint, and both of these are connected. Both side plates and both top plates were clamped using the bands 32a and 32b.
[0005]
In addition, since the pipe duct joint is merely a side plate portion 30 constituted by a simple plate member, the cover plate 33 of the pipe duct joint is particularly formed when some external force is applied from the vertical direction of the pipe duct joint. In some cases, the pipe duct joint is easily deformed, for example, it is depressed or the side wall portion 30 is bent.
In order to prevent such deformation, it is necessary to take measures so that the deformation is difficult to occur particularly at the opening edge in the Y direction. For these reasons, as described above, particularly when connecting in the Y direction, the band members are used to reinforce each edge.

[Problems to be solved by the invention]
However, when the connection procedure in the X direction and the connection procedure in the Y direction are different as in the above-described conventional technique, particularly when connecting in the Y direction, the duct of the piping duct D is used by using the connection band 32 as described above. Since it was necessary to sandwich the top plate 19 and the like, the connection work was extremely complicated. Not only that, but also when removing the top plate of the piping duct joint for maintenance of wiring and the like, the removal work has become complicated.
[0007]
Moreover, in order to increase the strength of the side wall part 30 formed by bending as much as possible, it is necessary to set the width of the side wall part 30 large. However, as a result, the size along the Y direction of the pipe duct joint is the sum of the occupied width of the wiring / piping 1 to be laid and the width of the side wall portion 30, so the size of the piping duct joint is necessary for the wiring / piping 1. It was more than the size. As described above, the installation area of the pipe duct joint increases, and the shape of the pipe duct joint in the X and Y directions becomes anisotropic. As a result, the location where the pipe duct joint is installed may be restricted. The degree of freedom was inferior.
[0008]
Accordingly, an object of the present invention is to eliminate the above-described conventional problems, improve the connection efficiency of the piping duct, and provide a piping duct joint having sufficient strength.
[0009]
[Means for Solving the Problems]
[Configuration 1]
As described in claim 1, the pipe duct joint according to the present invention has a bottom plate member whose bottom body has a substantially rectangular shape, and a column member that is configured separately from the bottom plate member and fixes the lid body. It is characterized in that it is constructed by being attached to each corner of the bottom plate member.
[Function and effect]
If it is the structure which attaches the pillar member comprised separately from the baseplate member to the said baseplate member like this structure, it will become possible to use the pillar member which has arbitrary cross-sectional shapes, for example. If the cross-sectional shape can be arbitrarily determined, the rigidity of the column member can be freely increased, and the arrangement space of the column member can be greatly reduced.
In addition, when the rigidity is reduced and the width of the column member is reduced, only the space necessary for actually laying various wires and pipes needs to be secured inside the pipe duct joint. Further, there is no inconvenience that the width of the bent portion unnecessarily increases the size of the pipe duct joint. Therefore, a compact pipe duct joint can be formed.
[0010]
[Configuration 2]
As described in claim 2, the pipe duct joint according to the present invention may be one in which a ridge line extending in a direction perpendicular to the bottom plate member is formed by two plate-like portions as the column member.
[Function and effect]
If a column member that forms a ridge line by two plate-like parts is used as in this configuration, a highly rigid column member can be obtained with a very simple configuration. For example, two plate members are abutted with each other so as to form a perpendicular surface, and the abutted portions are welded to form a column member, or a single plate member is simply bent at a substantially right angle. A pillar member can be formed.
As a result, even when a piping duct is connected to the column member, it is possible to prevent inconveniences such as the column member being bent and deformed.
[0011]
[Configuration 3]
As described in claim 3, the pipe duct joint according to the present invention can be configured by providing each of the column members with a duct mounting portion protruding in two directions.
[Function and effect]
As in this configuration, in the case where each of the column members is provided with a duct mounting portion that protrudes in two directions, it is possible to connect a pipe duct from two directions to one column member. For example, it is possible to connect the pipe duct from four directions to the pipe duct joint by setting the two directions as a right angle direction. In this case, it becomes possible to connect both side wall parts of one piping duct to the attachment part of the column member to which these side wall parts are attached. And the said connection point can be similarly performed about the piping duct from four directions.
In other words, with this configuration, since all pipe ducts to be connected can be connected in the same manner, there is no restriction that pipe ducts having different shapes must be connected as shown in the conventional example. . For this reason, it is not necessary to consider the arrangement direction when arranging the pipe duct joint, and the installation work of the pipe duct joint can be made efficient.
[0012]
[Configuration 4]
As described in claim 4, the pipe duct joint according to the present invention may have a screw hole for attaching the pipe duct formed in the duct attachment portion.
[Function and effect]
As in this configuration, if a screw hole is formed in the duct attachment portion, the piping duct can be attached to the attachment portion very easily and quickly. In particular, if screw holes are formed in all the duct mounting portions, the necessity for connection using a band member is eliminated. Duct installation work can be made simple and quick.
[0013]
[Configuration 5]
As described in claim 5, the pipe duct joint according to the present invention can be configured such that the lid body has a top plate portion and four side plate portions.
[Function and effect]
If the lid is composed of a top plate portion and four side plate portions as in this configuration, the lid body has a box shape, and the rigidity of the lid body is greatly improved. Therefore, by attaching the lid to the bottom body, the overall strength of the pipe duct joint is improved. As a result, after the wiring / pipe laying operation is finished, the pipe duct joint is easily deformed even if some external force acts on the pipe duct joint or the pipe duct connected to the pipe duct joint. Can be prevented. As a result, there is no inconvenience that a gap is generated between the pipe duct joint and the pipe duct, and it is possible to effectively prevent inconveniences such as sunlight entering the pipe duct joint and rainwater entering easily. As a result, it is possible to reliably protect the internal wiring and piping.
[0014]
[Configuration 6]
As described in claim 6, the pipe duct joint according to the present invention has a side plate portion corresponding to a mounting position of the pipe duct among the four side plate portions, substantially parallel to the top plate portion and outward. A first protruding portion that protrudes is formed, and a second protruding portion that protrudes substantially in the same plane as the bottom plate member is formed on each side portion of the bottom plate member that corresponds to the mounting position of the piping duct. In addition, when connecting the piping duct, the first projecting portion and the second projecting portion, and the duct mounting portion projecting toward the piping duct are configured to be inserted into the piping duct. can do.
[Function and effect]
When connecting a piping duct to the piping duct joint of the present invention, only the duct mounting portion is used, and the connection using the other top plate portion and bottom plate member is not performed. That is, in the pipe duct joint of this configuration, the first protrusion, the second protrusion, and the duct mounting part are inserted into the pipe duct, but the first protrusion and the second protrusion The part mainly serves as a positioning means for the duct top plate and the duct bottom plate when the pipe duct is attached to the pipe duct joint or after the pipe duct is attached. For example, when a pipe duct is attached, the duct top plate is brought into contact with the first projecting portion, thereby facilitating alignment of mounting holes provided in the duct side plate and the duct attaching portion. And if it is a piping duct coupling of this structure, since it is not necessary to use a band-shaped member etc. as mentioned above, a duct side plate and a duct attachment part can be attached very rapidly.
Moreover, since it is not necessary to use a band-shaped member etc. as mentioned above, the connection part of a piping duct and a piping duct coupling becomes clear, and the external appearance of a connection part can be improved.
Further, after the piping duct is attached, even if any external load is applied to the duct top plate, the first projecting portion prevents the duct top plate from being depressed and the deformation amount of the piping duct is reduced. It is also possible to expect an effect such as minimizing the problem.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
(Overview)
The piping duct joint of the present invention will be described with reference to the drawings.
In FIG. 1, the external appearance perspective view of the piping duct coupling which concerns on this invention is shown. FIG. 2 shows an exploded perspective view of the pipe duct joint.
The piping duct joint according to the present invention includes a bottom body S and a lid body F that can be attached to and detached from the bottom body S. A plurality of piping ducts D can be connected to the piping duct joint. FIG. 1 shows an example in which four pipe ducts D are connected.
[0016]
(Bottom body)
The said bottom body S is a part which receives and supports various wiring and piping 1 laid in a piping duct joint. As shown in FIG. 2, the bottom body S includes a bottom plate member 2 and a column member 3.
[0017]
The said baseplate member 2 is a part which receives and supports the various wiring and piping 1 laid in the inside of a piping duct coupling. In the present embodiment, the bottom plate member 2 is a substantially rectangular plate member. If it is formed in a rectangular shape as in this configuration, a maximum of four piping ducts D can be connected. Moreover, the bottom plate member 2 can be easily manufactured by configuring the bottom plate member 2 in a simple plate shape.
[0018]
In addition, in this embodiment, although the said baseplate member 2 is comprised with the plate-shaped member literally, it is not restricted to the said structure. For example, there are cases where it is desired to lay the wiring / piping 1 over the outside and inside of the piping duct joint. In such a case, an opening may be provided in the bottom plate member 2. Therefore, the bottom plate member 2 is not limited to a perfect plate-like member, and may be, for example, a frame shape.
[0019]
A leg fixing hole 4 is provided at a predetermined position of the bottom plate member 2. For example, as shown in FIG. 6 or 7, this is used when the gate-shaped leg 5 is attached to the back surface of the bottom plate member 2 using a screw member or the like.
[0020]
In the present embodiment, the bottom member S is configured by attaching column members 3 formed separately from the bottom plate member 2 to the respective corners of the bottom plate member 2. The column member 3 is a member for securing a space for laying various wiring / piping 1 above the bottom plate member 2 and for connecting the lid F.
[0021]
In the pipe duct joint according to the present invention, the column member 3 is formed separately from the bottom plate member 2 as described above. Therefore, the column member 3 having any strength or rigidity can be attached to the bottom plate member 2. For example, in this embodiment, as shown in FIGS. 2 and 3, the column member 3 has two plate-like portions 7 that form ridge lines 6 extending in a direction perpendicular to the bottom plate member 2. Yes. That is, the column member 3 is configured using a member whose cross-sectional shape in a plane parallel to the bottom plate member 2 is, for example, L-shaped.
[0022]
By using the column member 3 having such a cross-sectional shape, the rigidity of the column member 3 can be increased, and the cross-sectional space of the column member 3 can be greatly reduced.
Further, when the rigidity is increased and the width of the column member 3 is reduced, it is sufficient to secure only a space necessary for actually laying various wirings and pipes 1 inside the pipe duct joint. As described above, there is no inconvenience that the width of the bent portion unnecessarily increases the size of the pipe duct joint. Therefore, a compact pipe duct joint can be formed.
[0023]
FIG. 3 shows details of the column member 3. FIG. 3A shows a plan view of the column member 3, and FIG. 3B shows a side view and FIG. 3C shows a rear view. Is shown.
The column member 3 has a shape in which two plate-like portions 7 are connected. These connecting portions form ridge lines 6 extending in a direction perpendicular to the bottom plate member 2. The two plate-like portions 7 may be configured to be bent, for example, or may be integrated by welding at the position of the ridgeline 6. In the case of bending, the ridgeline 6 has a phase as viewed microscopically. On the other hand, when comprised by welding, the said ridgeline 6 can be finished in edge shape. It is considered that there is no difference in the strength of the column member 3 regardless of which method is used. Therefore, the column member 3 may be formed by appropriately selecting depending on the ease of manufacture or circumstances such as the appearance.
[0024]
A duct mounting portion 8 is connected to the plate-like portion 7. In this embodiment, the duct attachment part 8 is attached to the two plate-like parts 7, respectively. That is, as shown in FIG. 3 (a), the two duct mounting portions 8 are formed so as to form a right angle with each other, and can be connected to two piping ducts D connected from two directions forming the right angle. is there.
The duct mounting portion 8 is provided with two duct mounting holes 9 for connecting the pipe duct D. For example, the piping duct D is connected by inserting a screw member through the duct mounting hole 9 and a mounting hole provided on the piping duct D side.
[0025]
In the present embodiment, the duct mounting hole 9 forms a simple opening. Therefore, in the case of this configuration, as will be described later, the piping duct D is attached using a screw member and a nut member. If it is this structure, the duct attaching part 8 can be comprised very easily.
The duct mounting hole 9 may be formed as a tap hole, for example. In this case, it is only necessary to screw the duct member into the duct mounting plate 9 while allowing the screw member to pass through the duct side plate 21 of the pipe duct D, so that the pipe duct D can be joined very quickly.
[0026]
Of the both ends of the column member 3, a lid attachment portion 10 is provided at an end portion on the side where the lid F is attached. As shown in FIGS. 3A and 4, here, the end of the plate-like portion 7 is bent to form the lid attachment surface 12 so as to coincide with the plane of the top plate portion 11 of the lid F. is doing. A lid mounting hole 13 for fixing the lid F is formed on the lid mounting surface 12, and a nut member 14 is welded to the back surface of the lid mounting portion 10. Thus, after the lid F is placed on the lid mounting surface 12, the screw F is screwed into the nut member 14 while passing the screw member 15 through the lid F and the lid mounting portion 10. Fix it.
[0027]
The column member 3 is attached to the bottom plate member 2 by spot welding in this embodiment. As shown in FIG. 3 (c), the lower end portions of the two plate-like portions 7 are bent to form a fixing portion 16 that comes into contact with the bottom plate member 2. The fixing portion 16 is brought into contact with the back surface side of the bottom plate member 2. Therefore, of the both surfaces of the fixed portion 16, the surface on the side facing the lid mounting portion 10 becomes the fixed surface 17. Spot welding is performed while the fixing surface 17 and the back surface of the bottom plate member 2 are in contact with each other to fix the column member 3.
[0028]
Thus, if the method of attaching by spot welding is used, since the bottom plate member 2 and the column member 3 are substantially integrated, the reliability of the attachment relating to the column member 3 can be improved. Moreover, since the part which uses for spot welding can be formed only by bending the one end side of the column member 3, the manufacturing efficiency of the said bottom body S can be improved.
[0029]
The column member 3 can be attached to the bottom plate member 2 using a screw member 15a as shown in FIG. That is, it is possible to form column member mounting holes in the corners of the bottom plate member 2 and the fixing portions 16 at the lower end of the column member 3 and fix them using the screw members 15a and the nut members 14a. In this case, as shown in FIG. 5, if the nut member 14a is welded to the bottom plate member 2, the screw member 15a can be easily screwed.
[0030]
In this configuration, for example, the pipe duct joint can be assembled at the pipe laying site. In other words, the pipe duct joint is in a disassembled state until it is brought into the site, and the overall volume is small. Therefore, a pipe duct joint having excellent portability can be obtained.
[0031]
(Lid)
The lid F is for covering the laying portion after laying various wiring / piping 1 on the bottom plate member 2.
As shown in FIG. 2, the lid F according to the present invention includes a plate-like top plate portion 11 and side plate portions 18 formed around the top plate portion 11. Here, the top plate part 11 whose planar shape is a square is shown. Of course, the planar shape of the top plate 11 is not limited to a square, and may be a rectangular shape.
[0032]
In the present embodiment, the top plate portion 11 and the side plate portion 18 are connected by welding. When this method is used, it is not necessary to produce a bending mold or the like, and it is possible to simplify the equipment used for manufacturing and reduce the manufacturing cost of the piping duct joint.
Moreover, the welding part can be comprised in edge shape by welding the top-plate part 11 and the side-plate part 18. FIG. Therefore, a specific effect can be exhibited also on the design.
[0033]
In the present embodiment, the side plate portions 18 adjacent to each other are also welded. Thus, the intensity | strength of the cover body F can be improved remarkably by connecting the circumference | surroundings of the top-plate part 11 by the side-plate part 18, and making it a kind of box shape. Therefore, when the lid F is attached to the bottom body S, a pipe duct joint with extremely high rigidity can be formed, and the internal wiring / piping 1 can be reliably protected.
[0034]
(Piping duct installation procedure)
FIG. 6 shows a procedure for attaching the piping duct D to the piping duct joint.
First, the leg portion 5 is attached to the pipe duct joint and installed at a predetermined position. The piping duct D to be connected is brought close to the piping duct joint. At this time, the top plate portion 11 of the pipe duct joint portion and the duct top plate 19 of the pipe duct D are removed. The duct bottom plate 20 and the pair of duct side plates 21 are connected in advance.
[0035]
As shown in FIG. 2 and FIG. 6, in this embodiment, the side plate portion 18 corresponding to the mounting position of the piping duct D among the four side plate portions 18 is substantially parallel to the top plate portion 11 and outward. The 1st protrusion part 22 which protrudes in this is formed. On the other hand, in each side portion of the bottom plate member 2, a second projection portion 23 that protrudes substantially in the same plane as the bottom plate member 2 is formed on a side portion corresponding to the attachment position of the piping duct D.
[0036]
When the piping duct D is brought close to one side portion of the piping duct joint, the duct bottom plate 20 is formed on the column member 3 so as to be positioned below the second projecting portion 23 as shown in FIG. The duct mounting portion 8 is aligned with the pipe duct D and the pipe duct joint so as to be inside the duct side plate 21. In this state, the connecting screw member 24 is passed through the duct side plate 21 and the duct mounting portion 8 from the outside of both the duct side plates 21, and from the inside of the piping duct D to the screw member 24. The nut member 25 is screwed.
The nut member 25 can be welded to the back side of the duct side plate 21 in advance. In that case, the mounting operation of the screw member 24 is speeded up.
[0037]
Thus, when connecting the piping duct D to the piping duct joint of the present invention, only the duct mounting portion 8 is used, and the connection using the other top plate portion 11 and the bottom plate member 2 is not performed. Therefore, the installation work of the piping duct D is extremely simple, and the efficiency related to the installation work of the piping duct joint can be greatly improved.
[0038]
In the pipe duct joint of the present invention, the first projecting portion 22 and the second projecting portion 23 are mainly used when the duct duct D is attached to the duct duct joint or after the duct duct joint. 19 and the duct bottom plate 20 function as positioning means.
For example, when the pipe duct D is attached, the duct top plate 19 is brought into contact with the first projecting portion 22 to automatically align the duct attachment holes 9 provided in the duct side plate 21 and the duct attachment portion 8. Can be done automatically.
In addition, after the pipe duct D is attached, even if any load is applied to the duct top plate 19 from the outside, the first protrusion 22 prevents the duct top plate 19 from being depressed. The deformation amount of the piping duct D can be minimized.
[0039]
(effect)
As described above, when the pipe duct joint of the present invention is used, the column member 3 having an arbitrary strength or rigidity is attached to the bottom plate member 2, so that the sectional space of the column member 3 can be greatly reduced. As a result, the pipe duct joint can be made compact.
Furthermore, the strength of the entire pipe duct joint is remarkably improved by attaching the rigid lid body F to the strength of the column member 3. Therefore, when attaching the duct duct D to the duct duct joint, only the duct side plate 21 need be connected. Since the connection of the duct side plate 21 can usually be done by screwing, the installation work efficiency of the piping duct D can be greatly increased.
[0040]
(Another embodiment)
<1> In the above embodiment, an example in which the piping duct D is attached to the piping duct joint from four directions has been shown. Of course, the number of the piping ducts D connected to the piping duct joint is limited to four. Instead, it may be two or three. About the side part which does not connect the piping duct D, it is good also as preparing and attaching a cover member for exclusive use, and you may weld the side-plate part 18 which does not have an opening from the beginning.
Thus, the piping duct joint can be attached to any position as long as the plurality of piping ducts D are gathered. As a result, it is possible to increase the degree of freedom in determining the laying route of various wiring / piping 1.
