Description

【０００１】
【産業上の利用分野】
本発明は、例えば、構造体（例えば、床や天井や壁）を貫通する挿通体（例えば、配管やケーブル）の周囲を、防火のために耐火封止する充填材を保持する支持具に関し、詳しくは構造体に設けられた貫通孔に挿通された長尺体の挿通部分の周囲空間で、充填材を支持自在な貫通孔の充填材支持具に関する。
【０００２】
【従来の技術】
従来、この種の貫通孔の充填材支持具としては、図５に示すように、貫通孔２への充填材Ｊの充填方向前方側で、前記貫通孔２内に充填される前記充填材Ｊを受止め自在な一体構成の環状支持部３０を設け、前記貫通孔２の開口部の周囲に各別に係止自在な複数の係止片部３１を設け、前記支持部３０に対して前記係止片部３１を各別に連結する複数の連結部３２を設けたものがあり、前記係止片部３１によって構造体１に該充填材支持具を係止させて、支持部３０の中心部分に形成された挿通孔に長尺体Ｐを挿通させて、長尺体Ｐと貫通孔壁２ａとの間に充填材Ｊを詰め込んで前記支持部３０で支持するものであった。
【０００３】
【発明が解決しようとする課題】
前述した従来の貫通孔の充填材支持具によれば、支持部を貫通孔内に押入して、係止片部によって構造体にこれを係止させ、その後に支持部に形成された挿通孔に長尺体を挿通させ、挿通させた長尺体と貫通孔壁とのあいだに充填材を指で詰め込むといった、手間の掛かる工事にならざるを得なかった。
そこで、本発明の目的は、上記問題点を解消し、貫通孔に長尺体を設置した後に手間をかけずに充填材支持具を設置すると同時に、充填材を前記貫通孔内に簡単に充填できる貫通孔の充填材支持具を提供するところにある。
【０００４】
【課題を解決するための手段】
この目的を達成するための本発明の「貫通孔の充填材支持具」の特徴構成は以下のとおりである。即ち、
本発明の特徴構成は、構造体に設けられた長尺体を挿通する貫通孔への充填材の充填方向前方側で、前記貫通孔内に充填される前記充填材を受止め自在な支持部を備えると共に、前記支持部を前記構造体に係止自在な係止部を備えたフレームを設け、前記貫通孔への前記充填材の充填方向後方側で、前記貫通孔に挿通された長尺体と前記構造体とにわたって配置自在な蓋部材を設け、前記フレームと前記蓋部材とを連結する連結部を設け、前記蓋部材で覆う空間を縮小自在にする縮小操作部を、前記蓋部材に設けてあり、前記蓋部材の内周面に、前記蓋部材を前記フレームに係合させた状態での前記長尺体の挿通部分に近づくほど前記フレームから遠ざかる傾斜面部を形成してある点にある。
なお、前記連結部をネジ嵌合自在に形成すると共に、前記連結部のねじ込み操作に伴って前記蓋部材が前記構造体側に近接するように前記連結部の螺進方向を設定して前記縮小操作部を構成してもよく、また、押込操作によって前記蓋部材内に侵入し、且つ、固定される押込操作部を設け、前記押込操作部と前記蓋部材とを結合する結合部を、前記押込操作部と前記蓋部材とに設けて前記縮小操作部を構成してもよく、さらに、前記結合部をネジ嵌合自在に形成すると共に、前記結合部のねじ込み操作によって前記押込操作部が前記蓋部材に侵入するように前記結合部の螺進方向を設定して上記結合部を構成してもよく、また、前記蓋部材への前記貫通孔の外方から内方への力を受けて前記蓋部材と前記フレームとを複数段階に係合可能に形成して前記連結部を構成してもよい。
そして、前記の特徴構成において、前記蓋部材で覆う空間を縮小自在にする縮小操作部に代えて、前記蓋部材で覆う空間を加圧自在にする加圧操作部を、前記蓋部材に設けておいてもよい。
さらに、上記の各構成において、前記貫通孔の径方向に前記フレームを分割形成してもよく、前記フレームが、前記支持部と前記係止部とに分離自在に形成してあってもよく、前記貫通孔の径方向に前記蓋部材を分割形成してもよく、そして、前記蓋部材に予め前期充填材が充填されてあればさらによい。
【０００５】
【作用】
本発明の貫通孔の充填材支持具の特徴構成によれば、前記フレームを設けるとともに、前記蓋部材を設けてあるから、充填材は前記支持部材と前記蓋部材との間の内部空間に閉じ込められ、前記連結部を設けるとともに、前記縮小操作部を前記蓋部材に設けてあるから、前記蓋部材に充填材を充填しておくだけで、後は、前記縮小操作部を操作すれば、前記内部空間は縮小し、充填材は結果として充填空間内に押し込まれることになる。なお、前記連結部をネジ嵌合自在に形成すれば、連結後にねじ込み操作によって、また、前記押込操作部を設けることによって、また、前記連結部を前記蓋部材と前記フレームとを複数段階に係合可能に形成することによって前記蓋部材を押しつけるだけでも、前記内部空間を容易に圧縮でき、また、前記結合部をネジ嵌合自在に形成することによって、ねじ込み操作するだけで簡単に前記押込操作部を前記蓋部材に容易に侵入させることができるので、前記内部空間をさらに容易に圧縮でき、その結果、容易に充填材を充填空間内に押し込むことができる。さらに、充填材を押し込んだ状態で前記連結部は固定されるので、仮に火災が発生して充填材が膨張しても膨張した充填材が前記蓋部材に遮られるので、外に漏れ出すことを防止できる。なお、前記蓋部材と長尺体との間を封止可能な封止材を縮小操作部の操作の前に設けてあれば充填材の漏れ出しをさらに確実に防止することができる。
そして、前記蓋部材に、前記加圧操作部を設けた場合には、前記内部空間に外部から加圧流体を圧入し、その加圧流体の前記内部空間内で占める容積分だけ充填材を収容する空間の容積を減少し、さらに前記充填材に前記貫通孔に向けての圧力を附加することができるので、その加圧力によって容易に充填材を充填空間内に押し込むことができる。充填材が外に漏れ出すことを防止できるのは前記の特徴構成と同様である。
さらに、上記の各構成において、前記貫通孔の径方向に前記フレームを分割形成すれば、長尺体を貫通孔に挿通した後に充填材支持具を取り付けうるので、充填材支持具の取付が容易になり、前記フレームを、前記支持部と前記係止部とに分離自在に形成しておけば、長尺体の外径寸法に応じた支持部を前記係止部に組み合わせて用いることができ、前記貫通孔の径方向に前記蓋部材を分割形成しておけば、前記長尺体を前記貫通孔に挿通した後に前記フレームを構造体に取りつけ、その後から容易に前記蓋部材を取りつけることができ、そして、前記蓋部材の内周面に前記傾斜面部を形成してあれば、蓋部材に充填した充填材を貫通孔に向けて押し込む力が大きく働くので、充填材の前記充填空間内への押し込みが更に容易になり、また、前記蓋部材に予め前期充填材が充填されてあれば、充填材を取り扱う手間が省け、さらに、充填材を充填空間のサイズに合わせて適量充填しておくことができるのでなおさら取り扱いやすくなると同時に、充填材の過不足を防ぐことが出来る。
【０００６】
【発明の効果】
従って、本発明の貫通孔の充填材支持具を用いることにより、長尺体を貫通孔に挿通後、フレームを貫通孔に係止させ、更に充填材を充填した蓋部材をこのフレームに取り付け、縮小操作部を操作するだけで、また、この縮小操作部に代えて加圧操作部を用いた場合には、その加圧操作部を加圧するだけで、簡単に充填材を充填空間内に充填でき、且つ、その後の充填材の漏れだしを防止できるので、構造体の貫通孔に長尺体を挿通した後の防火を確実にできる。
【０００７】
【実施例】
以下に本発明の実施例を図面に基づいて説明する。
図２は、スラブ１（構造体の一例）に設けられた配管挿通用の貫通孔２に、空調配管Ｐ（長尺体の一例）を挿通させて、貫通孔２の周壁部２ａと、空調配管Ｐとの隙間に充填材Ｊを充填して、防火貫通部を構成してある状況を示す縦断面図で、前記充填材Ｊは、本発明の「貫通孔の充填材支持具」の一例である充填材支持具Ｓによって、前記貫通孔２内に支持されている。そして、前記空調配管Ｐは、銅管からなる配管本体３ａを発泡樹脂製断熱部材３ｂで被覆して形成してある冷媒管３と、ケーブル４とから構成してある。
また、前記充填材Ｊは、例えば、前記スラブ１で仕切られた上下空間の一方で火災が発生した場合に、前記貫通孔２を通して上下空間の他方側へ類焼するのを防止できる防火貫通部を構成するために、熱膨張性を有するパテＪ１で構成してある。前記パテＪ１によれば、火災による熱によってパテＪ１そのものが膨張し、仮に、空調配管Ｐが燃焼したり収縮しても、その周囲に広がって隙間を埋めつくし、煙や炎が貫通孔２を通過しにくいようにすることが可能である。
前記充填材支持具Ｓについて説明すると、前記貫通孔２に嵌入して係止自在なフレームＦと、このフレームＦに取付自在な蓋部材１０と、前記フレームＦに係合させた状態で前記充填材Ｊを受止め自在な支持板１４とを設けて構成してある。この支持板１４は、前記フレームＦの支持部５と協同して前記充填材Ｊを受止めることになる。
前記フレームＦは、前記貫通孔２への前記充填材Ｊの充填方向前方側（即ち、下方側）で、前記支持板１４を受止め自在な支持部５と、前記支持部５を前記スラブ１に係止自在な係止部６とを、複数の帯金部材７で一体的に連結して構成してある。この帯金部材７は、その下端部を前記支持部５に接合してあると共に、上端部分は、外側へ屈曲させて前記係止部６に接合してある。
具体的には、図１に示すように、前記支持部５は、環状の板金部材で構成してある。この支持部５は、同図（イ）に示すように径方向に二分割形成し、両分割支持部５ａ，５ａから構成してある。両分割支持部５ａ，５ａどうしは、図に見られるように、その連結部分に嵌め合い構造を設けてあり、径方向に沿って互いを嵌め合うことによって、同図（ロ）に示すように一体的に連結することが可能である。
前記係止部６は、環状の板金部材によって形成してあり、径方向に二分割して構成してある。そして、板金部材からなる両分割係止部１８，１８は、一端部どうしを重ねた状態で鳩目１６ａからなるヒンジ部１６を介して揺動自在に連結してある。また、両分割係止部１８，１８の他端部には夫々係合部１７が設けられており、両係合部１７が重なった状態で厚み方向に貫通する固定用穴１７ａを両分割係止部１８，１８に各別に設けてあり、両分割係止部１８，１８を環状姿勢に整えて貫通孔２の開口周囲に係止させた状態で、前記鳩目の穴１６ａと固定用穴１７ａとに釘やネジを挿通させてスラブ１に固定できるようにしてある。さらに、環状の係止部６の外周部には、前記蓋部材１０を内嵌め自在な環状の縦壁部６ａを設けてあり、この環状の縦壁部６ａには、前記蓋部材１０を内嵌めするに伴って、蓋部材１０の後記筒状部１０ａに備えた切起こし片１０ｂが自身の弾性変形を伴いながら乗り越えて係合自在な複数の係合孔６ｂを各別に設けてあり、この縦壁部６ａも前記係止部６とともに径方向に二分割してある。
前記蓋部材１０は、図１に示すように、底無しの「おわん」をふせたような形に形成してあり、その内側に図２に示すように、前記蓋部材１０の内側には前記「おわん」の縁に沿って前記「おわん」の内周面から前記縁の側に向けて円筒状の筒状部１０ａを一体に設けてあり、この筒状部１０ａに前記縦壁部６ａの係合孔６ｂに係合可能な前記切起こし片１０ｂが夫々に対応する位置に各１個設けてある。この蓋部材１０を前記切起こし片１０ｂで前記縦壁部６ａに係止させ、さらに前記貫通孔２に向けて押しつけると、これに伴って、前記切起こし片１０ｂが前記係合孔６ｂに順次係合するようにしてあり、さらに、この筒状部１０ａに内嵌して円筒状の縮小部材２０がその軸芯方向に摺動自在に設けられており、図３に示すように、この縮小部材２０が前記蓋部材１０の内方に向けて摺動し、同図（イ）から同図（ロ）のようにパテＪ１を前記貫通孔２内の充填空間Ｖに向けて押し込むようになっている。こうして前記筒状部１０ａとこの縮小部材２０とで縮小操作部Ｌを形成している。
前記蓋部材１０は、図３に示すように、その内周面と前記筒状部１０ａ、縮小部材２０とに亘って充填材Ｊを充填しておいた後に前記フレームＦに取り付けられ、前記フレームＦに係合させた状態で、スラブ１とその貫通孔２に挿通し空調配管Ｐの束との隙間を塞ぐことができるように寸法設定して形成してある。
この蓋部材１０もまた、フレームＦと同様に、図１に示すように径方向に二分割に形成してあり、夫々の分割蓋部材８には蓋係合部９が形成されており、前記蓋係合部９は、一方の分割蓋部材８から他方の分割蓋部材８裏面側に延出する裏当て板部９ａと、前記裏当て板部９ａに形成した雌ネジ部９ｂと、前記両分割蓋部材８を合体させた状態での前記裏当て板部９ａに重なる前記他方の分割蓋部材８部分に形成されたネジ穴部９ｃとによって構成してあり、前記ネジ穴部９ｃを通して雌ネジ部９ｂにボルトを螺合させることによって、両分割蓋部材８どうしを連結固定し、一体的な蓋部材１０とすることができる。
また、蓋部材１０の内周面には、蓋部材１０をフレームＦに係合させた状態で空調配管Ｐの挿通部分に近づくほど前記フレームＦから遠ざかる傾斜面部Ｍを形成してあり、充填空間に充填されたパテＪ１が膨張する際に、前記傾斜面部Ｍに接当しながら傾斜下手側に誘導され易くしてある。従って、仮に、空調配管Ｐが蓋部材１０を貫通する部分に隙間があったにしても、その隙間でパテＪ１が締め付けられるから、外部へ漏れ出し難くすることが可能となる。
前記縮小部材２０も二分割されており、図１（イ）に示すように、一方の分割縮小部材２１の周方向両端部は周方向先端に尖端を有する径方向内方の面が傾斜した楔状に形成され、その傾斜面部に軸芯方向に形成された突条２１ｂと凹条２１ａが夫々並設されており、また、他方の分割縮小部材２２の周方向両端部は周方向先端に尖端を有する径方向外方の面が傾斜した楔状に形成され、その傾斜面部にも軸芯方向に形成された突条２２ｂと凹条２２ａが夫々並設されている。両分割縮小部材２１，２２を夫々両分割蓋部材８，８の筒状部１０ａに内嵌して、前記両分割蓋部材８を合体させる際に、両分割縮小部材２１，２２は、これらの両端部の凹条２１ａ，２２ａに夫々両端部の突条２２ｂ，２１ｂが夫々係合し、同図（ロ）に示すように、これらの分割縮小部材２１，２２はそのまま一体化されて縮小部材２０となるようにしてある。
上述の前記係合孔６ｂと前記切起こし片１０ｂとの係合構造は、貫通孔２に充填したパテＪ１が膨張しても、その力を受けて前記フレームＦと蓋部材１０とが外れ難くなるように形成してある。
前記支持板１４は、図１に示すように、板金製で環状に形成してあり、その外周部には係止手段１５が設けられている。この支持板１４もまた径方向に二分割されて、分割支持板２４，２４によって構成してある。支持板１４は、挿通させる空調配管Ｐの最大外径にほぼ等しい寸法になるようにその内径を設定してあり、空調配管Ｐと支持板１４との間に大きな隙間ができないように形成してある。なお、前記空調配管Ｐの外径が異なる場合には、その値に合う内径に形成した別の支持板を使用する。また、支持板１４の外径は、前記フレームＦの各帯金部材７の内方にきっちり納まるように寸法設定してある。
さらに、前記支持板１４の外周部には、前記帯金部材７に対して、周方向に沿った係合方向で係合自在な複数の係合部１４ａを、前記帯金部材７に対応する位置に各別に設けてある。前記係合部１４ａは、図示のとおり、平面形状を『Ｌ』字形に形成してあり、前記帯金部材７に係合した状態においては、支持板１４を、前記支持部５に対して貫通孔２の径方向内側へ移動するのを阻止できるように構成してある。即ち、前記係合部１４ａによって係止手段１５を構成する。
本実施例の充填材支持具Ｓを用いた防火貫通部の形成方法は、空調配管Ｐを挿通させた後（空調配管Ｐを後記のフレームＦを設置した後から挿通させることも可）、貫通孔２にフレームＦを一体化した上で係止状態に設置し、一体化した支持部５上に支持板１４を一体化して載置すると共に帯金部材７に前記係合部１４ａを係合させ、その上からパテＪ１を充填した一体化した後の蓋部材１０をフレームに係合させることによって簡単に実施することができる。
つまり、図３（イ）に示すように予め両分割蓋部材８，８に両分割縮小部材２１，２２夫々の端部を夫々内嵌させた状態で、前記蓋部材１０の傾斜面部Ｍならびに筒状部１０ａ及び縮小部材２０の各内面と空調配管Ｐとの間の内部空間Ｋに相当する部分にパテＪ１を充填しておき、両分割蓋部材８，８を空調配管Ｐを内挿させる状態で合体させて、両分割縮小部材２１，２２が合体して円筒状になった縮小部材２０を前記フレームＦの環状の縦壁部６ａに内挿し、そのまま近接させて前記筒状部１０ａを前記縦壁部６ａに内嵌する。ここで、前記縮小部材２０はスラブ１に接し、パテＪ１を内部空間Ｋ内にほぼ封入することができる。次いで同図（ロ）に示すように、前記蓋部材１０を前記貫通孔２に向けてさらに押しつける。この結果、前記縮小部材２０は、前記筒状部１０ａに沿って前記傾斜面部Ｍに向けて押し込まれ、その結果、前記内部空間Ｋは縮小し、パテＪ１は前記傾斜面部Ｍに押されて貫通孔２内の充填空間Ｖに向けてはみ出し、前記支持板１４に達するので、パテＪ１を前記長尺体Ｐと前記貫通孔２の周壁部２ａとの間の充填空間Ｖ内に充填することができるようになる。
前記充填材支持具Ｓによれば、挿通させる空調配管Ｐの外径寸法に合う支持板１４を選択するだけでフレームＦの兼用化を図りながら、且つ、空調配管Ｐの挿通部周りに隙間のでき難い状態に防火貫通部を構成することができると共に、前記縮小操作部Ｌを設けてあることによって、予め内部空間Ｋ内に充填した充填材Ｊを前記充填空間Ｖ内に押し込み充填することができ、且つ、パテＪ１の膨張力が蓋部材１０に作用してもパテＪ１が外部へ膨出することを防止でき、より信頼性の高い防火貫通部を形成することが可能となる。

〔別実施例〕
以下に別実施例を説明する。
〈１〉前記フレームＦは、先の実施例で説明した支持部５と係止部６とを一体的に形成してあるものに限定されるものではなく、例えば、前記支持部５と係止部６とを着脱自在な別部材から構成してあってもよい。
また、径方向に二分割に形成してあるものに限らず、例えば、三分割以上の複数分割構成や、分割せずに一体的に構成してあるものであってもよい。
〈２〉前記縮小操作部Ｌは、縮小部材２０と蓋部材１０の筒状部１０ａをネジ嵌合させて構成してもよく、前記縮小部材２０を環状の縦壁部６ａに係合させて、前記縮小部材２０に螺設したネジと前記筒状部１０ａに螺設したネジを螺合させ、蓋部材１０を螺進して内部空間Ｋを縮小するようにしてあってもよい。また、前記筒部材１０ａと前記環状の縦壁部６ａをネジ嵌合させるように構成してもよい。
〈３〉前記縮小操作部Ｌは、押し込み操作によって前記蓋部材１０内に侵入し、且つ、固定される押込操作部１２を設け、この押込操作部１２と前記蓋部材１０とを結合する結合部１３を前記押込操作部１２と前記蓋部材１０とに設けるようにしてあってもよく、例えば、図４に示すように、蓋部材１０の前記「おわん」状の部分に押込操作部１２を設けてあってもよい。つまり、前記「おわん」状の部分に開口部分を設けてその開口部分に雌ネジ部１３ｂを螺設するとともに、この雌ネジ部１３ｂに螺合可能な雄ネジ部１３ａを備えたボルト状の押込部材１２ａを螺合させるようにして前記雄ネジ部１３ａと前記雌ネジ部１３ｂとで結合部１３を構成し、前記蓋部材１０に前記押込部材１２ａを前記結合部１３で結合し、この押込部材１２ａを前記蓋部材１０の内方に向けて螺進させて押し込み、内部空間Ｋを減容させるように構成してもよい。この押込操作部１２は必要に応じて複数箇所に設けてもよい。
なお、前記押込操作部１２の結合部１３を蓋部材１０の長尺体Ｐの貫通部に設けてもよく、この場合は、前記押込部材１２ａを筒状に形成し、螺進可能なようにフランジを設けることにしてもよい。また、この場合、前記押込部材１２ａは前記蓋部材１０と同様に二分割してあってもよい。
さらに、前記結合部１３は螺合させるものに限らず、前記押込部材１２ａを押し込むに従ってその位置にその押込部材１２ａを固定できるように構成してあれば良く、例えば段階的に係止できるように構成してあってもよい。
〈４〉前記連結部１１を構成するのに、前記筒状部１０ａの内面に上方への移動を阻止する、平行な断面鋸刄状の係合段を設けるとともに、前記縦壁部６ａの前記切起こし片１０ｂを下方に向けて係止力を作用させるように設けて連結部１１とすると同時に縮小操作部Ｌとし、蓋部材１０を押し込みながら段階的に前記縮小部材２０に係合させつつ内部空間Ｋを縮小するようにしてもよい。この係合段を前記縦壁部６ａに設けた係合孔６６と同数の複条ネジ（例えば、４条ネジ）とすれば、取り外しに際しては蓋部材１０をネジ回すだけで前記蓋部材１０を簡単に取り外すことができるようになる。
〈５〉前記縮小操作部Ｌに代えて、前記蓋部材１０にその内周面と、前記係止部６及び長尺体Ｐの外面との間の内部空間Ｋに圧力を加える手段を設けて加圧操作部としてもよい。この加圧手段としては、流体圧を用いてもよく、また、蓋部材１０の内面を充填材に対して加圧可能に形成してあってもよい。
〈６〉前記蓋部材１０の形状は「おわん」状のものに限らず、前記縮小操作部Ｌ或いは前記加圧操作部の構成に合わせて適宜形状を選定でき、例えば中心部に貫通孔を備えた中空円盤を用いて前記押込操作部１２或いは前記加圧操作部を構成する場合には、円筒状の外壁に中心部に貫通孔を有する底部を備えた形状の蓋部材１０を用いると効果的である。
さらに、この場合、中空円盤を前記蓋部材１０の前記構造体１側に向かって凹状に形成された曲面状或いは回転曲面状に形成して、その外周縁を前記係止部６側に向けるとともに、上記円筒状の外壁の内面に摺動するようにすれば、前記充填空間Ｖ内に充填材Ｊを押し込むのに有効である。
〈７〉前記充填材Ｊは、フレームＦを貫通孔に挿入係止した後で、そのフレームＦの中に押し込んで充填してもよく、また、予め縮小操作部Ｌを操作する前の蓋部材１０の中と前記環状の縦壁部６ａの内部とに充填しておき、縮小操作部Ｌの操作によって充填材Ｊを前記充填空間Ｖ内に押し込んで充填すると効率的である。なお、これは加圧操作部の操作によってもよい。
〈８〉前記縮小部材２０は、パテＪ１を前記蓋部材１０の内周面及び筒状部１０ａの内側にはみ出し充填した後に蓋部材１０の筒状部１０ａに内嵌させてもよく、また、前記係止部６上の長尺体Ｐの周囲の前記縦壁部６ａの内側にパテＪ１を充填し、さらに盛り上げておいてもよい。

[Action]
According to the characteristic configuration of the filler support for a through-hole of the present invention, since the frame is provided and the lid member is provided, the filler is confined in an internal space between the support member and the lid member. Since the connecting portion is provided and the reduction operation portion is provided in the lid member, the lid member is simply filled with a filler, and then the reduction operation portion is operated. The interior space shrinks and the filler is consequently pushed into the filling space. If the connecting part is formed so as to be screw-fitable, it is possible to engage the connecting part with the lid member and the frame in a plurality of stages by a screwing operation after the connection and by providing the pushing operation part. The inner space can be easily compressed by simply pressing the lid member so that the coupling member can be formed, and the coupling portion is formed so as to be screw-fit so that the pushing operation can be performed simply by screwing. Since the portion can be easily penetrated into the lid member, the internal space can be more easily compressed, and as a result, the filler can be easily pushed into the filling space. Further, since the connecting portion is fixed in a state where the filler is pushed in, even if a fire occurs and the filler expands, the expanded filler is blocked by the lid member, so that it leaks outside. Can be prevented. In addition, if the sealing material which can seal between the said cover member and an elongate body is provided before operation of the reduction operation part, the leakage of a filler can be prevented further reliably.
And when the said pressurization operation part is provided in the said cover member, a pressurized fluid is press-fitted in the said interior space from the outside, and the filler is accommodated for the volume which the pressurized fluid occupies in the said interior space. The volume of the space to be reduced can be reduced, and further, a pressure toward the through hole can be applied to the filler, so that the filler can be easily pushed into the filling space by the applied pressure. The filler can be prevented from leaking out in the same manner as the above-described characteristic configuration.
Further, in each of the above-described configurations, if the frame is divided and formed in the radial direction of the through hole, the filler support can be attached after the elongated body is inserted into the through hole, so that the filler support can be easily attached. If the frame is formed so as to be separable into the support part and the locking part, a support part corresponding to the outer diameter of the long body can be used in combination with the locking part. If the lid member is divided and formed in the radial direction of the through hole, the frame can be attached to the structure after the elongate body is inserted into the through hole, and the lid member can be easily attached thereafter. If the inclined surface portion is formed on the inner peripheral surface of the lid member, the force for pushing the filler filled in the lid member toward the through-hole greatly acts, so that the filling material enters the filling space. It becomes easier to push in, and If the filling member is filled with the filler in the previous period in advance, the trouble of handling the filler can be saved.Furthermore, the filler can be filled in an appropriate amount according to the size of the filling space. Excess or deficiency of filler can be prevented.

And both the division | segmentation latching | locking parts 18 and 18 consisting of a sheet-metal member are connected so that rocking | fluctuation is possible via the hinge part 16 which consists of eyelet 16a in the state which accumulated the one end part. In addition, an engaging portion 17 is provided at the other end of each of the split locking portions 18, 18. A fixing hole 17 a that penetrates in the thickness direction in a state where both the engaging portions 17 overlap with each other is provided on both split engagements. The stop portions 18 and 18 are provided separately from each other, and in the state in which both split locking portions 18 and 18 are arranged in an annular posture and locked around the opening of the through hole 2, the eyelet hole 16a and the fixing hole 17a are provided. A nail or a screw can be inserted into the slab 1 so that it can be fixed. Further, an annular vertical wall portion 6a into which the lid member 10 can be fitted is provided on the outer peripheral portion of the annular locking portion 6, and the lid member 10 is disposed inside the annular vertical wall portion 6a. In accordance with the fitting, the cut and raised piece 10b provided in the cylindrical portion 10a of the lid member 10 is provided with a plurality of engaging holes 6b that can be engaged with each other while being elastically deformed. The vertical wall portion 6 a is also divided into two in the radial direction together with the locking portion 6.

The cut and raised pieces 10b that can be engaged with the joint holes 6b are respectively provided at positions corresponding to the cut and raised pieces 10b. When the lid member 10 is locked to the vertical wall portion 6a by the cut-and-raised piece 10b and further pressed against the through hole 2, the cut-and-raised piece 10b is sequentially brought into the engagement hole 6b. Further, a cylindrical reduction member 20 is fitted in the cylindrical portion 10a so as to be slidable in the axial direction. As shown in FIG. The member 20 slides inward of the lid member 10 and pushes the putty J1 toward the filling space V in the through hole 2 as shown in FIG. ing. In this way, the cylindrical portion 10a and the reduction member 20 form a reduction operation portion L.

The portion corresponding to the internal space K between the inner surface of each of the shape portion 10a and the reducing member 20 and the air conditioning pipe P is filled with putty J1, and the air conditioner pipe P is inserted into both the divided lid members 8 and 8. The reduced member 20 in which the two split reduction members 21 and 22 are combined to form a cylindrical shape is inserted into the annular vertical wall portion 6a of the frame F, and is brought close to the cylindrical member 10a so that the cylindrical portion 10a is It fits in the vertical wall 6a. Here, the reducing member 20 is in contact with the slab 1, and the putty J1 can be substantially enclosed in the internal space K. Next, the lid member 10 is further pressed toward the through hole 2 as shown in FIG. As a result, the reducing member 20 is pushed toward the inclined surface portion M along the cylindrical portion 10a. As a result, the internal space K is reduced, and the putty J1 is pushed by the inclined surface portion M and penetrates. Since it protrudes toward the filling space V in the hole 2 and reaches the support plate 14, the putty J <b> 1 can be filled in the filling space V between the elongated body P and the peripheral wall portion 2 a of the through hole 2. become able to.
According to the filler support tool S, a gap can be formed around the insertion portion of the air conditioning pipe P while the frame F can be used only by selecting the support plate 14 that matches the outer diameter of the air conditioning pipe P to be inserted. The fire penetration penetrating portion can be configured in a difficult state, and by providing the reduction operation portion L, the filling material J previously filled in the internal space K can be pushed and filled into the filling space V. In addition, even if the expansion force of the putty J1 acts on the lid member 10, it is possible to prevent the putty J1 from bulging to the outside, and it is possible to form a more reliable fire-penetrating part.
