Description

【０００１】
【発明の属する技術分野】
本発明は、鉄筋コンクリート造の壁式構造や、ラーメン構造の建築物の帳壁に好適に使用出来る外壁用の断熱複合パネルに関するものであり、鉄筋コンクリート造建築の技術分野に属するものである。
【０００２】
【従来の技術】
〔特許文献１〕特許第２９９９９８０号（特願平９−１５２６２８号）公報
〔特許文献２〕特開平５−１７１７２３号公報
鉄筋コンクリート造建築物にあっては、外断熱工法として、断熱複合パネルをコンクリート壁などの躯体に型枠併用として配置し、コンクリート壁などと一体化して外壁を形成しており、断熱複合パネルを帳壁として単体で採用することはなかった。
しかし、鉄骨造建築物にあっては、従来よりパネルを鉄骨造躯体に帳壁として取付ける工法が採用されており、本出願人等が特願平９−１５２６２８号として提案し、特許第２９９９９８０号として特許登録されている断熱複合パネルがある。
【０００３】
〔従来例１〕
図８は、特許第２９９９９８０号のパネルであって、該パネルは、上枠、下枠及び両側枠から成る枠体の外面に、貫通孔を有する成形セメント板の３枚を並列接続した形態でＺクリップを介して止着し、枠体の内面には内装板（石膏ボード）を配置し、硬質ウレタンフォームの枠体内への注入充填発泡によって、セメント板、枠体、及び内装板を、硬質ウレタンフォーム断熱層によって一体化したものであり、鉄骨造建築物の帳壁パネルとして採用すれば、セメント板に対する断熱層の現場での吹付け作業も、内装面材の取付作業も不要となり、建築工期の大幅な短縮化を可能とする、極めて有用な複合パネルである。
【０００４】
〔従来例２〕
図９は、特開平５−１７１７２３号に開示されたパネルであり、ビーズ法ポリスチレンフォーム断熱材に補強材を組込んだ型枠パネルであって、補強材を内装下地兼用とした断熱材一体の型枠パネルである。（岩倉化学工業（株）製、商品名：スタットボード）
詳しくは、幅９１０mmで、長さは１８２０mm、２１００mm、２４００mm、２７００mm、３０００mmの各種があり、厚さは４５mm、５０mm、６５mm、７５mm、１００mmの各種サイズがあり、幅６０mm、厚さ２０mmの特殊プラスチック製補強材（下地材）を３本組込んだものであって、補強材は、図９（Ｂ）に示す如く、パネルをコンクリート型枠に用いる際に、端太材の機能を奏すると共に、内装面材打付け用の下地材となるものである。
そして、断熱材両側面には相欠けを施して、隣接パネルと相欠け連結するものである。
【０００５】
【発明が解決しようとする課題】
しかし、従来例１の断熱複合パネル（図８）にあっては、鉄骨造躯体へ帳壁として取付ける際に、クレーン等で吊上げて配置するが、吊上げ時のパネル変形防止のため、また、製作時の硬質ウレタンフォームの注入発泡時の堰止めのために側枠は必要不可欠であるが、該パネルをコンクリート躯体に建付ければ、側枠部が熱橋（ヒートブリッジ）となって断熱機能を低下するため、側枠に対する煩雑な熱橋阻止手段（図８（Ｃ）の緩衝体付設）を施す必要があった。
【０００６】
更に、ウレタンフォームのパネル枠体内への注入発泡に際しても、ポリマーと発泡剤との２液混合の管理面、広いパネル面積への均斉注入面等から、均斉な気泡を有する均斉な断熱層の形成は煩雑、且つ熟練を要する作業であった。
また、一体化された内装板（石膏ボード）は、施工取扱中に欠損や汚染の損傷を受ける危険があり、特に、鉄筋コンクリート造建築物に採用すれば、コンクリート打設前の散水、又は石膏ボードの床スラブなどのコンクリートとの当接、等による吸水によって石膏ボード（内装板）にカビが発生し、美観上の問題及びアトピー等の健康問題や、保管衣服の損傷の問題等があった。
【０００７】
また、従来例２（図９）の型枠パネルは、補強材が、コンクリート型枠組み時のパネル補強、及び、内装ボードの下地材機能を奏するが、電気設備、例えば、コンセント、スイッチ、テレビの配線作業を施す際には、断熱材を欠落して電線を埋設する溝堀をする問題がある。
【０００８】
従って、本出願人が、先に開発に成功し、特願２００１−０２５１４２号として提案した、断熱複合パネルを単体で帳壁とする鉄筋コンクリート造建築物に、従来例１の該断熱パネル（図８）を適用すれば、石膏ボード（内装板）が床スラブに当接するため、コンクリートの配合水を吸水してカビを発生させる問題がある。
【０００９】
更に、硬質ウレタンフォームの発泡凝固時の自己接着力によって、セメント板の枠体への係止部のＺクリップが固定され、枠体、セメント板、及び内装板相互も固定されて複合パネル内での層間変位の吸収作用が生じないため、地震時には、内装板、特に石膏ボードの衝合部に亀裂の発生する問題がある。
【００１０】
本発明は、従来例１（特許第２９９９９８０号）の断熱複合パネル（図８）、及び従来例２（特開平５−１７１７２３号）の型枠パネル（図９）の、上述の如き、種々の問題点を解決、又は改善し、鉄筋コンクリート造建築物の帳壁外壁パネルとして有効に採用出来る、しかも、はるかに低コストで提供可能な、新規、且つ実用性の極めて高い断熱複合パネルの提供を可能とするものである。
【００１１】
【課題を解決するための手段、及び作用】
本発明の帳壁用断熱複合パネル１は、例えば図１に示す如く、通気層２ｈを備えたセメント板層２と、セメント板層２の上端及び下端に取付けた鋼材から成る上下枠４ａ，４ｂと、上下枠４ａ，４ｂ間でセメント板層２に層着した成形断熱層３とを含む断熱複合パネルであって、上枠４ａ及び下枠４ｂとセメント板層２とをボルト７ａによってルーズホール形態で締着し、成形断熱層３は、少なくとも、表面に長手方向の配線溝５Ｇを備えた縦方向の条片下地材５ｂを含む、複数の埋設露出した下地材５ａ，５ｂを備え、且つ、上下枠のうち、少なくとも、上枠４ａ内面を耐火被覆材６で被覆して成形断熱板をセメント板層２に層着一体化したものである。
【００１２】
尚、上枠４ａ、及び下枠４ｂは、セメント板層２を止着し、且つパネルの上端及び下端を規定してパネルの建物躯体への取付機能を備えたものであれば良いが、断面アングル形態のアングル鋼材であれば、水平辺４Ｈでセメント板層を止着し、立上り辺４Ｆでパネル端縁規定兼パネル取付機能が兼備出来、充分な機械的強度を発揮出来るので好ましく、等辺山形鋼が特に好ましい。
【００１３】
また、成形断熱層３としては、耐水性、及びコンクリート付着性を有する合成樹脂発泡成形板が好ましく、典型的には硬質ウレタンフォーム板である。
また、セメント板層２と枠４ａ，４ｂとのボルト７ａによる「ルーズホール形態の締着」は、セメント板層２と上枠４ａ又は下枠４ｂとの間に大きな層間変位応力が作用した際に、セメント板層と枠とにすべりを発生させるために、図２（Ａ）の如く、ボルト７ａの径ｄ７に対して、セメント板の孔Ｈ４の径ｄ４及び上下枠４ａ，４ｂの孔Ｈ３の径ｄ３を共に大径でルーズ孔とすることも、ボルト７ａに対して上下枠孔Ｈ３のみをルーズ孔としても、或いはセメント板孔Ｈ４のみをルーズ孔としても良い。
【００１４】
また、「埋設露出」の意味は、条片下地材５ａ，５ｂが、完全埋設して表面のみが露見している状態も、表面が突出形態で露出している状態も含む意味である。
そして、条片下地材５ａ，５ｂの表面５ｆが断熱層表面３ｆと面一の場合は、下地材５ａ，５ｂに内装面材（内装面板）２７を取付ける際の、断熱層表面３ｆへの防湿シート（図示せず）の介在が容易となり、条片下地材表面５ｆが断熱層表面３ｆより突出している場合は、内装面材２７と成形断熱層３間に空隙層が出来て、内装面材２７と成形断熱層３の音の共振が阻止出来、遮音性が向上する。
【００１５】
また、断熱層に埋設した下地材５ａ，５ｂは、石膏ボード等の内装面板２７のネジ等での張設に有効なものであり、配線溝５Ｇは、内装面板２７の張設前に室内への電気配線に供すものであるから、配線溝５Ｇを備えた下地材５ｂのみは断熱層３に縦方向（パネル上下方向）に配置する必要があるが、他の単なる内装面板２７の張設のみに供する下地材５ａは、図１の縦方向配置でも、或いは、条片下地材５ｂの溝５Ｇに干渉しない形態の横方向（パネル横断方向）配置でも良い。
【００１６】
また、耐火被覆材６は、パネル１を張設した建物の内面の火災に対処するものであるから、火災対策上は上枠４ａ部のみに付与すれば十分であるが、耐火被覆材６で被覆しても、ボルト７ａのルーズホール挙動の規制が少ないため、下枠４ｂ部も耐火被覆材６で被覆保護するのが有利である。
【００１７】
また、耐火被覆材６は、汎用高分子材の厚みの小さなテープ状材が好都合であり、断熱性、耐久性、安全性（繊維系のグラスウール、ロックウールとは異なり、作業時に材料の飛散がなく、また、火災発生時に有毒ガスの発生がなくて、取扱上、衛生上安全なもの）、難燃性に優れたものが良く、典型的には、ナイフで簡単に切断が出来、また粘着性があるフイブロック（積水化学工業（株）商品名）である。
【００１８】
フイブロックの２mm厚のテープは、燃焼時、約３０mm厚に膨張して耐火被覆材となり、幅も自由に製作が可能で、上下枠４ａ，４ｂに粘着使用するための適当な粘度を備えている。
従って、曲げ、切断及び接着が容易であるため、被覆作業の困難なボルトなどへの適用も可能である。
そして、フイブロックの耐火被覆材６は、アングル鋼枠４ａ，４ｂ及びボルト７ａに自己粘着で止着出来る。
【００１９】
また、本発明の断熱複合パネルにあっては、鉄筋コンクリート造建築の帳壁パネルとして用れば、層間変形角（耐震設計基準：１／２０００以下）が小であるため、セメント板層２と枠４ａ，４ｂとのルーズホール形態締着により必要耐震力が発揮出来、断熱層として成形断熱材を用いることと相俟って、枠も鋼材から成る上枠４ａと下枠４ｂとの使用のみと出来る。
しかも、耐火被覆材６は、ルーズホール形態締着による層間変位への対応作用も保証すると共に、パネル内面への耐火性も付与する。
【００２０】
従って、従来の如き、強固、且つ重い枠体が不要となり、断熱層の枠体内での充填発泡管理も不要となるため、均斉な断熱層を備え、且つ、耐震性、耐火性をも具備し、鉄筋コンクリート造建築の帳壁パネルとして充分な必要機能を具備する断熱複合パネル１が、大幅なコストダウンにより提供可能となる。
【００２１】
また、本発明断熱複合パネル１は、本出願人が先に開発に成功した鉄筋コンクリート造壁式構造建築物（特願２００１−０２５１４２号）に帳壁パネルとして採用することにより、非耐力壁部の外壁型枠工の省略とパネルの低コスト化とが相俟って、鉄筋コンクリート造外断熱建築物が画期的な建築費低減の下に提供可能となる。
しかも、成形断熱層３に埋設下地材５ａ，５ｂが存在するため、内装工事での電気配線が、成形断熱層への溝堀欠損を生ずることなく、容易、且つきれいに実施出来、内装面材の張設も下地材５ａ，５ｂの存在によって容易に実施出来る。
【００２２】
従って、本発明断熱複合パネル１は、本出願人が先に開発に成功した鉄筋コンクリート造壁式構造建築物（特願２００１−０２５１４２号）に帳壁パネルとして採用することにより、非耐力壁部の外壁型枠工の省略と、パネルの低コスト化と、更には、電気配線及び内装面材の合理的施工とが相俟って、鉄筋コンクリート造外断熱建築物が、建築費の画期的低減の下に提供可能となる。
【００２３】
また、該帳壁用断熱複合パネル１にあっては、通気層が上下貫通孔２ｈであり、上下枠４ａ，４ｂがアングル鋼材であるのが好ましい。
この場合、セメント板層２と上下枠４ａ，４ｂとのルーズホール形態締着は、図２（Ａ）に示す如く、貫通孔２ｈの内側に平ナット７ｂを入れて上枠（下枠）の水平辺４Ｈ側からボルト７ａで締着すれば良く、パネル外面に露出しない形態で作業性良く実施出来る。
また、上枠４ａ，下枠４ｂも入手容易な等辺山形鋼が採用出来る。しかも、通気層が上下貫通孔２ｈであるため、パネル１を空気の上下導通可能に上下に連結するのも容易である。
【００２４】
また、セメント板層２と上下枠４ａ，４ｂとのルーズホール形態の締着は、図２（Ａ）に示す如く、セメント板層２の内側板厚部Ｐｔに穿設したボルト挿入孔Ｈ４、及び対応する枠４ａ，４ｂの水平辺４Ｈのボルト挿入孔Ｈ３より小径のボルト７ａを、枠の水平辺４Ｈ側から貫通孔２ｈ内の平ナット７ｂに締着するのが好ましい。
この場合、セメント板層２と枠４ａ，４ｂの両方がルーズホールであるため、若干の上下左右の寸法調整も可能であって取付作業が容易であり、しかも、層間変位対応可能なルーズホール締着が得られる。
【００２５】
また、ルーズホールとしては、図２（Ｃ）の如く、枠４ａ，４ｂの水平辺４Ｈのボルト挿入孔Ｈ３がセメント板層２のボルト挿入孔Ｈ４と同径であってパネル上下方向の長孔であるのが好ましい。
建物躯体に固定された上下枠４ａ，４ｂとセメント板層２との層間変位は、セメント板層２が躯体に対して回動して変位を吸収するが、その変位はボルト７ａのルーズホールＨ３内の上下動生起となるため、上下枠４ａ，４ｂのボルト挿入孔Ｈ３がルーズホール径であって、しかも上下方向の長孔であれば、耐震設計値以上の不慮の層間変位にも対処可能となる。
【００２６】
また、本発明パネル１にあっては、セメント板層２が一側端には凹部２１を、他側端には突起２２を具備しているのが好ましい。
この場合、図３（Ｃ）の如く、帳壁形成時のパネル１相互の左右連結は、凹部２１と突起２２との不燃パッキング２３を介在した嵌合でスムーズに実施出来、セメント板層２相互を隙間なく、且つ平滑に接続出来るため、作業性及び耐火性が向上する。
【００２７】
また、本発明パネル１にあっては、セメント板層２が、一側端には凹部２１を、他側端には突起２２を具備したセメント板２Ｐの複数枚を、各凹部２１と突起２２との不燃パッキング２３を介在した衝合並列接続であるのが好ましい。
尚、不燃パッキング２３は両面接着タイプが好ましく、例えば、ＳＣブランケット（新日鉄化学（株）商品名）の採用が可能である。
【００２８】
外壁材としてのセメント板は、押出成形体をローラー上を移動させてオートクレーブ室で養生させるが、衝撃によるひび割れや、養生の際の反りの発生等、製造面からは幅が狭い方が有利であり、従って、コスト面、品質面で有利な幅狭のセメント板２Ｐを用意して複数枚を必要パネル幅１Ｗに接続するのが有利である。
しかも、図３（Ｂ）の如く、凹部２１と突起２２との不燃パッキング２３を介在した衝合接続と出来るため、連結部（目地）２Ｇも隙間のない接続と出来、接続一体化作業もスムーズに実施出来て、あたかも１枚のセメント板の如き耐火性を具備したものとなる。
【００２９】
また、本発明パネル１にあっては、耐火被覆材６が断熱性、耐久性及び難燃性のテープ状材であり、且つ、図２（Ａ）の如く、上下枠４ａ，４ｂ及びボルト締着部を被覆しているのが好ましい。
この場合、被覆材６は、典型的には、常温時には２mm厚であり、火災時には約３０mm厚に膨張して耐火被覆材となる両面が自己接着能を備えたフイブロック（商品名）である。
【００３０】
従って、上枠４ａや下枠４ｂの内面への張着も、ボルト７ａ及び座金７ｃへの張着も容易であり、成形断熱層３に接するパネル１の金属部分が耐火被覆材６で完全に被覆出来るため、室内側での火災による成形断熱層３の燃焼時にも、上下枠及び取付金具部の火災による劣下を最小限に抑制出来、断熱複合パネル１に耐火機能が付与出来る。
【００３１】
また、セメント板層２と成形断熱層３とを、柔軟性を有する弾力性接着剤Ａｄによって層着するのが好ましい。
弾力性接着剤は慣用のもので良く、例えば、エポキシ樹脂系のボンドエフレックス（コニン（株）商品名）の採用が可能である。
セメント板層２と成形断熱層３とを弾力性接着剤で層着した場合は、鉄筋コンクリート造建築物の微少な基準層間変形角（耐震設計基準：１／２０００）内で生起するセメント板層２と成形断熱層３との微少な層間変位（セメント板面と断熱層面との界面すべり）にも対応可能となり、成形断熱層３の表面に仕上げ張設する石膏ボード等の内装面板相互の衝合角部での欠損やクラック発生が最小限に抑制出来る。
【００３２】
また、本発明パネルにあっては、図２（Ａ）の如く、断熱層厚３Ｔが上下枠厚４Ｔより大であるのが好ましい。
この場合、本発明パネルにあっては、セメント板層２が通気層２ｈを備えているため、外壁としての必要強度を備えて軽量となり、上下枠４ａ，４ｂの枠厚４Ｔも十分な強度保有の下に断熱層厚３Ｔより小と出来る。
そして、図２（Ａ），（Ｂ）の如く、上下枠の立上り辺４Ｆの先端縁４ｅが断熱層表面３ｆより内側となり、先端縁４ｅは、成形断熱層３の被り厚３ｒで被覆されるため、上下の立上り辺４Ｆの建物躯体（床スラブＳ）との直接接触が回避出来る。
【００３３】
従って、取付金物Ｍの存在する場所では、上下枠４ａ，４ｂ→連結ピンＭｐ→支持板Ｍｓ→床スラブＳのわずかな熱橋は生じるが、パネル幅の大部分では、図６（Ｂ）の如く、床スラブＳに当接するのは、成形断熱層３と、パネル間目地２Ｇ´に介在する断熱材２５のみであり、実質上、断熱複合パネル１から建物躯体（床スラブＳ）への熱橋は阻止出来る。
【００３４】
また、本発明パネル１の上下枠は、上枠４ａの立上り辺４Ｆが取付孔Ｈ１、及び両端部のアイボルト締着用孔Ｈ２を備え、下枠４ｂの立上り辺４Ｆが、上枠４ａの取付孔Ｈ１の対応位置に取付孔Ｈ１を備えているのが好ましい。
アイボルト締着孔Ｈ２を上枠４ａ両端部に穿設しておけば、パネル１の吊上げ用のアイボルト（図示せず）装着により、パネル１の建付け作業が容易となる。
【００３５】
また、上枠４ａ及び下枠４Ｂの各取付孔Ｈ１は、図５（Ａ）の如く、上下枠４ａ，４ｂを取付金物Ｍの取付ピンＭｐに係止するものであるので、取付ピンＭｐを取付金物Ｍの支持板Ｍｓに螺入固定し、上下枠の取付孔Ｈ１を取付ピンＭｐ挿入用のピン孔としても良く、或いは、図５（Ｂ）の如く、上枠４ａの取付孔Ｈ１をネジ孔として取付ピンＭｐを螺入固定し、支持板Ｍｓの孔及び下枠４ｂの取付孔Ｈ１をピン孔としても良い。
従って、本発明パネル１は、鉄筋コンクリート造建築物への帳壁パネルとしての建付けが容易となる。
【００３６】
【発明の実施の形態】
〔セメント板層２（図３）〕
図３（Ａ）は、図６（Ａ）の３Ａ−３Ａ線の横断面図であり、セメント板層２は、図３（Ａ）に示す如く、３枚の成形セメント板２Ｐの並列接続で構成する。各成形セメント板２Ｐは、幅２Ｗが５９０mmで長さＬ１が２８８０mm、厚さ２Ｔが６０mmであり、一側端には突起２２を、他側端には凹部２１を備え、長さ方向の貫通孔２ｈを備えている。
そして、各セメント板２Ｐの上下両端部の貫通孔２ｈの内側板厚部Ｐｔには、ボルト挿入孔Ｈ４（図２（Ａ））を穿設する。
【００３７】
これら成形セメント板２Ｐの並列接続は、各凹部２１の底に、図３（Ｂ）の如く、両面接着性不燃パッキング２３として、厚さ１２．５mmのＳＣブランケット（新日鉄化学（株）商品名）を充填して各突起２２を不燃パッキング２３に当接すると共に、セメント板２Ｐの内側の板厚部Ｐｔ端縁間にも両面接着性を有する断熱材２５を充填して接続する。
尚、各成形セメント板２Ｐの連結部（目地）２Ｇ（標準：１０mm）表面は、パネル張設後の目地仕上げ時に、図３（Ｂ）の如く、バッカ−２４´を介してシーリング２４を施す。
【００３８】
〔枠（図１、図４）〕
辺幅４Ｔが６５mmで厚さ６mmの等辺山形鋼（アングル鋼）の上枠４ａと下枠４ｂを枠体とするものであり、上枠４ａの立上り辺４Ｆには、図４の如く、パネル幅１Ｗの中央より左右対称の２ヶ所に、２個１対の取付孔Ｈ１（ネジ孔）を間隔ＨＬ（標準：１２０mm）開けて穿設し、両端部にアイボルト（図示せず）締着孔Ｈ２を設け、下枠４ｂには上枠４ａの取付孔Ｈ１の対応位置に取付孔Ｈ１（ピン孔）を設ける。
また、上枠４ａ及び下枠４ｂの水平辺４Ｈには、図２（Ａ）の如く、径ｄ７が１０mmのボルト７ａを挿通するための径ｄ３が１２mmのボルト挿入孔Ｈ３を、各成形セメント板２Ｐの両端の貫通孔２ｈのボルト挿入孔Ｈ４と符号するように穿設する。
【００３９】
〔成形断熱層（図３）〕
成形断熱層３は、図３（Ａ）に示す如く、２枚の並列接続で、３枚の並列接続セメント板２Ｐに対応させる。
また、断熱層は、７５mm厚（３Ｔ）の硬質ウレタンフォーム板であり、発泡成形時に、図１（Ｂ）に示す幅５Ｗが６０mmで厚さ５Ｔが２０mmの合成樹脂製下地材５ａと、図１（Ｃ）に示す如く、合成樹脂製下地材５ａの中央部に、幅ＧＷが２０mm、深さＧＴが１０mmの溝５Ｇを切削形成した溝付下地材５ｂとを、図３（Ａ）に示す如く、１枚の成形断熱層３の中央には溝付下地材５ｂを、両側には一般下地材５ａを、各パネル１の並設時には、各下地材５ａ，５ｂが等間隔となるように、所定間隔の縦方向で成形型内に配置し、断熱層表面３ｆと面一に埋設一体化する。
尚、溝付下地材５ｂは、電気配線用であるため、全パネルに配置する必要はないが、内装面材の張設下地材として機能すること、及び、パネルの製作上、管理上の合理化のため、各硬質ウレタンフォーム板毎に１本混入配置する。
【００４０】
〔断熱複合パネル１の製作〕
成形用プレス台（図示せず）に成形セメント板２Ｐを３枚並列接続したセメント板層２を載置し、各セメント板２Ｐの上部及び下部の両端の貫通孔２ｈの内側の板厚部Ｐｔに、図２の如く突設した、径ｄ４が１２mmのボルト挿入孔Ｈ４に、上下枠４ａ，４ｂの水平辺４Ｈのボルト挿入孔Ｈ３を符号して上枠４ａ及び下枠４ｂをセメント板層２上に載置する。
そして、貫通孔２ｈの内部から平ナット７ｂを当接し、径ｄ７が１０mmのボルト７ａを水平辺４Ｈ側から座金７ｃを介して挿入し、平ナット７ｂに締着し、図４の如く、上下枠４ａ，４ｂをセメント板層２に、各セメント板２Ｐの上部両端を上枠４ａに、下部両端を下枠４ｂにボルト７ａで固定する。
【００４１】
次いで、上枠４ａ及び下枠４ｂの立上り辺４Ｆ、水平辺４Ｈ及びボルト７ａ、座金７ｃに、断熱性、耐久性、難燃性を備えた両面接着テープ形態のフイブロック（商品名）を耐火被覆材６として自己接着力で被覆一体化する。
そして、幅６０mm、厚さ２０mmの合成樹脂製下地材５ａ，５ｂを面一に埋設保持した厚さ７５mmの硬質ウレタンフォーム板を、内面上下には、図２に示すように、予め上枠４ａ、下枠４ｂ及びボルト７ａの形状に符合して切欠け３Ｇを所要寸法に加工付与し、左右側面には厚さ中央部で相欠け２６ｐ，２６ｑ（図３（Ｃ））を付与し、セメント板層２上に柔軟性のある弾力性エポキシ樹脂系接着剤、ボンドエフレックス（コニシ（株）商品名）を用いて、下地材５ａ，５ｂを外側にして層着し、硬質ウレタンフォーム板３（成形断熱層３）をセメント板層２と一体化する。
この場合、上枠４ａ、下枠４ｂ及びボルト７ａに当接した耐火被覆材６は、自己接着力で硬質ウレタンフォーム板と一体化する。
【００４２】
尚、図２（Ａ），（Ｂ）に示す、枠４と硬質ウレタンフォーム板３との切欠け３Ｇによる間隙は、複合パネル側端辺（１ｓ）に紙テープを張着すれば、密閉空気層となり断熱効果は低下しない。
従って、得られるパネル１は、図２（Ａ），（Ｂ）に示す如く、上下枠４ａ，４ｂの内面及びボルト７ａと、成形断熱層３との界面に耐火被覆材６が介在し、且つ、上下枠４ａ，４ｂの立上り辺４Ｆ先端縁４ｅが断熱層の被り厚３ｒによって保護されたものとなり、上下枠４ａ，４ｂからのコンクリート躯体への熱橋を生じない耐火性断熱パネルとなる。
【００４３】
〔断熱複合パネル１の使用（図５、図６）〕
上述の実施形態で得られる断熱複合パネル１は、本出願人が特願２００１−０２５１４２号として先に提案した、断熱複合パネルを単体で帳壁とする新規な鉄筋コンクリート造外断熱建築物に適用すれば極めて有効なものである。
即ち、図５に示す如く、コンクリート床スラブＳの前端に、アンカー部Ｍａを介して固定した取付金物Ｍの支持板Ｍｓに挿入した取付ピンＭｐに、断熱複合パネル１の下枠４ｂを取付孔Ｈ１（ピン孔）を介して挿通係止し、パネル下面Ｆｂが床スラブ表面Ｓｆより下方で、雨水のパネル下端面Ｆｂから床スラブ表面Ｓｆへの侵入を阻止するように取付ける。
【００４４】
また、パネル上部にあっては、パネル上枠４ａの取付孔Ｈ１（ネジ孔）に取付ピンＭｐを螺入すると共に、取付ピンＭｐに支持板Ｍｓを嵌合した状態で、取付金物Ｍのアンカー部Ｍａを型枠内配筋と結合して上階床スラブ型枠内に固定し、床スラブ型枠内へのコンクリート打設によってパネル上端部の成形断熱層３（硬質ウレタンフォーム板）を固化コンクリートと当接一体化し、且つ、上枠４ａは床スラブＳの前端に埋設一体化した取付金物Ｍに取付ピンＭｐを介して取付けた状態で床スラブＳの前端に固定し、帳壁外壁を形成する。
そして、パネル１のみで帳壁形成後に、パネル内表面、即ち成形断熱層表面３ｆ、を洗浄清掃し、石膏ボード等の所定の内装面板２７（図７）を防湿シート（図示せず）を介在して条片下地材５ａ，５ｂに張設する。
【００４５】
この場合、条片下地材５ａ，５ｂは断熱層表面３ｆと面一に埋設されているため、下方床スラブ表面に不陸があっても、また、上方床スラブ型枠の組立て時にも、下地材５ａ，５ｂの干渉はなく、パネル１の下端及び上端の取付作業が容易に実施出来る。
そして、上階床スラブ型枠内へのコンクリート打設に際しても、成形断熱層３がコンクリート付着性大で吸水性小であるため、パネル１の上部内表面は床スラブＳ前端と隙間なく、且つ強固に一体化する。
【００４６】
また、コンクリート打設によって断熱層表面３ｆにコンクリート配合水が流出付着しても、床スラブ型枠解体後の断熱層表面３ｆでのカビの発生はない。
また、内装工事に際しては、断熱層表面３ｆが目視出来るので、例え水分が付着しても、条片下地材５ａ，５ｂが面一で埋設しているため拭取りが容易であり、成形断熱層３及び耐火被覆材６はカビを発生しないため、石膏ボード等の内装面板を下地材５ａ，５ｂを介して張設しても、パネル１面から内装面板へのカビの伝播汚染は生じない。
【００４７】
また、図７は壁内への電気配線説明図であって、（Ａ）は室内側略示図、（Ｂ）は（Ａ）のＢ−Ｂ断面を、（Ｃ）は（Ａ）のＣ−Ｃ断面を表わす図であって、コンクリート床スラブＳにあっては、図７（Ｂ）の如く、慣用の配線用コンクリートボックス配置手段によって、コンクリートボックス２９を床スラブＳの型枠内に配置して、コンクリートボックス２９を床スラブ前端下部に埋設し、コンクリートボックス２９から引出したＶＶＳ線３０を、溝付下地材５ｂの溝５Ｇ内に垂下して、図７（Ｃ）の如く、コンセント２８まで引張り、下地材５ｂの切込部５Ｈを介して電線を引出してコンセント一体枠２８ａ内に接続し、内装面板２７のコンセント挿入孔Ｈ２７にコンセント一体枠２８ａを嵌合してコンセント化粧カバー２８ｂを内装面板２７の表面に止着する。
【００４８】
従って、本発明実施形態のパネル１で形成した帳壁にあっては、成形断熱層３を何ら損傷することなく、且つ、容易にコンクリート床スラブＳから室内のコンセント２８への配線が出来、配線工事が合理化出来る。
しかも、ＶＶＳ線３０が、条片下地材５ｂの中央部の溝５Ｇ内への配線となるため、ＶＶＳ線が硬質ウレタンフォーム板（成形断熱層）の含有する反応触媒（アミン）による劣下も受けない。
【００４９】
尚、パネル１相互の左右連結部２Ｇも、図３（Ｃ）の如く、パネル１内のセメント板２Ｐ相互の接続目地２Ｇ（図３（Ｂ））同様に、パネル端縁の凹部２１と突起２２との不燃パッキング２３を介した衝合連結とし、成形断熱層３は、予め断熱材両側面に相欠け２６ｑ，２６ｐを付与して成形断熱層３の連続性を保つ。また、パネル相互の左右連結部２Ｇの表面は、パネル１内のセメント板２Ｐ相互の目地２Ｇ（図３（Ｂ））と共に、パネル張設後の外装仕上げで図３（Ｃ）の如く、バッカー２４´を介した耐火シーリング２４によって目地仕上げする。
【００５０】
また、パネル１相互の上下連結部２Ｇ´も、図６（Ｂ）の如く、断熱材２５を、上下パネルで挟着した形態で上枠４ａに載置し、セメント板２Ｐの内側板厚部Ｐｔでは、耐火シート２３´を介在してシーリング２４で閉じ、表側板厚部Ｐｔでは、外装仕上げでバッカー２４´を介した耐火シーリング２４によって、貫通孔２ｈの空気導通ａを保証して目地仕上げする。
【００５１】
従って、本発明実施形態の断熱複合パネル１で形成した帳壁外壁は、パネル１からコンクリート躯体への熱橋が阻止出来ると共に、電気配線も合理的に実施出来る。
そして、耐火面では、建物外部の火災に対しては、セメント板層２及び連結部（目地）の不燃パッキング２３及び耐火シート２３´が対処し、室内側からの火災に対しては、耐火被覆材６が対処する耐火性を具備し、また耐震面では、セメント板２Ｐと上下枠４ａ，４ｂとのルーズホール形態のボルト締着、及びセメント板層２と成形断熱層３との弾力性接着剤による層着によって、地震や強風時の建物揺れで生ずるセメント板層２と成形断熱層３との層間変位を吸収し、セメント板層２や断熱層上の仕上げ内装板（石膏ボード）の亀裂や欠損が抑制出来るものとなり、耐火、耐震性外壁となる。
しかも、カビ汚染の恐れのない内装面材仕上げが可能となる。
【００５２】
また、セメント板２Ｐと上下枠４ａ，４ｂとの取付けも、従来例１では、図８の如く、Ｚクリップで行うため、パネルの建付け時のセメント板の脱落を阻止するように、パネルを各セメント板対応で配置した取付片を用い、各セメント板対応の取付金物でコンクリート躯体に取付ける必要があったが、本発明では、セメント板をボルト７ａで上下枠４ａ，４ｂに取付けるため、実施形態例（図４、図６）の如く、１枚のパネル１内に３枚のセメント板２Ｐを用いても、パネル１のコンクリート躯体への取付けは、パネル両側の２個の取付金物で可能となる。
従って、取付金物Ｍの使用個数が減少出来、取付金物の部材コストの減少、パネル１の取付作業の容易化、が達成出来、取付金物Ｍの使用個数減少により、パネル１からコンクリート躯体への熱橋作用も減少出来る。
【００５３】
また、パネル枠体を上枠４ａと下枠４ｂのみとしたこと、及び断熱層３を成形断熱層としたことにより、断熱複合パネル１の製造コストを大幅に低減したことと、鉄筋コンクリート造建築物に於いて非耐力壁部を断熱複合パネル１のみの帳壁構造として外壁形成時の非耐力壁部のコンクリート型枠組み工を不要と出来ることとが相俟って、耐震耐火性鉄筋コンクリート造外断熱建築物が大幅な建築費低減により提供出来る。
【００５４】
〔その他〕
条片下地材５ａ，５ｂは、実施態様例（図１）ではパネルに対する縦方向配列であるが、横方向配列としても良い。
但し、配線用溝５Ｇを備えた下地材５ｂのみは縦方向配置が必要であり、他の下地材５ａは、溝５Ｇに干渉しないように配置すべきである。
また、溝付下地材５ｂにあっては、実施形態例（図１（Ｃ））では、配線溝５Ｇを中央部に配設したが、配線溝５Ｇを端部に配置すれば、条片下地材５ｂ上への内装面板のネジや釘の打込み作業が容易となる。
この場合は、断熱層との接触によって電線被覆材の劣下が生じないように、断熱層と電線被覆材とを材料選択すれば良い。
【００５５】
尚、縦方向配列で下地材表面５ｆを断熱層表面３ｆから突出させる場合は、下地材５ａ，５ｂ上端は床スラブ型枠組み作業に干渉しない高さ、即ち、床スラブＳの下面より下方とし、下地材５ａ，５ｂ下端は床スラブ表面Ｓｆより上部として床スラブ表面の不陸に対処可能とするのが良い。
また、成形断熱層３としては、硬質ウレタンフォームの表面を防湿シートでラミネートした断熱板等、成形断熱板に予め防湿処理を付与したものを採用すれば、パネルの内部結露防止がより確実となる。
【００５６】
また、耐震設計基準での層間変形角は、鉄筋コンクリート造壁式構造では１／２０００以下、鉄骨造、鉄筋コンクリートのラーメン構造では１／２００以下であり、本発明パネルは標準長２８８０mmの鉄筋コンクリート造用であるため、セメント板２Ｐと上下枠４ａ，４ｂとのルーズホール締着は、セメント板２ＰのルーズホールＨ４及び上下枠のルーズホールＨ３が１２mm径であり、締着ボルト７ａが１０mm径であれば耐震設計基準内での層間変位吸収の機能を充分達成するが、ルーズホールＨ３，Ｈ４の形状及びサイズは、より大きな層間変位吸収の面から、又は締着位置調整の面から適宜に決定すれば良い。
【００５７】
また、実施態様例では、セメント板層２と成形断熱層３との接着剤として柔軟な弾力性エポキシ樹脂系接着剤を適用したが、成形断熱層３としての合成樹脂成形板を浸蝕しない通常の接着剤を用いても、パネル１は、枠４ａ，４ｂとセメント板層２とのルーズホール締着により、耐震設計基準の層間変形角（１／２０００）内での層間変位吸収目的は達成出来る。
【００５８】
【発明の効果】
本発明断熱複合パネル１は、成形品としてのセメント板２Ｐ、成形品としての断熱層３、成形品としての上下枠４ａ，４ｂを組立て製作するため、従来の如き、合成樹脂の充填発泡圧に耐えるための強固、且つ重い枠体が不要となり、断熱層の枠体内での充填発泡管理も不要となるため、軽量化出来ると共に、均斉な断熱機能を奏する成形断熱層の接着形成により安価に製造出来る。
【００５９】
しかも、セメント板層が枠４ａ，４ｂとルーズホール形態で締着して層間変位対応可能としたための耐震性と、耐火被覆材６での上枠４ａ内面被覆による室内側からの火災対応、及びセメント板層２による外部からの火災対応が可能であるための耐火性とを備えた、鉄筋コンクリート造建築の帳壁パネルとして充分な必要機能を具備したパネルとなる。
【００６０】
また、成形断熱層を、柔軟性を有する弾力性接着材Ａｄによってセメント板層２に層着するため、成形断熱層３とセメント板層２との層間変位にも対処可能となり、地震時には、外装材としてのセメント板層２の亀裂、欠損の抑制のみならず、断熱層上に張設した内装面材の欠損も最小限に抑制出来る。
また、成形断熱層３が条片下地材５ａ，５ｂを埋設露出しているため、内装面材はパネルでの外壁形成後に容易に張設出来、溝５Ｇを備えた下地材５ｂの存在により、パネル内への電気配線工事も、断熱層に欠損を生じることなく容易に実施出来る。
【００６１】
しかも、成形断熱層３が耐水性であってパネル内側全面を覆っているため、内装面材にはカビ汚染が発生しない。
また、上下枠４ａ，４ｂの立上り辺４Ｆの先端縁４ｅが、成形断熱材の表面３ｆより被り厚３ｒを介して内側に位置しているため、上下枠４ａ，４ｂの建物躯体との当接がなくて熱橋（ヒートブリッジ）が発生しないことと、従来パネルの如き側枠からの熱橋作用のないこととが相俟って、本発明パネルは、熱橋作用防止面でも極めて有効な外壁を提供する。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating composite panel for an outer wall that can be suitably used for a wall structure of a reinforced concrete structure or a book wall of a building having a ramen structure, and belongs to the technical field of reinforced concrete construction.
[0002]
[Prior art]
[Patent Document 1] Japanese Patent No. 2999980 (Japanese Patent Application No. 9-152628)
[Patent Document 2] JP-A-5-171723
In reinforced concrete structures, as an external heat insulation method, heat insulating composite panels are placed on a concrete wall or other frame as a formwork, and are integrated with concrete walls to form an external wall. It was never used alone as a wall.
However, in the case of a steel structure building, a method of attaching a panel to a steel structure as a book wall has been conventionally adopted. The present applicants proposed as Japanese Patent Application No. 9-152628 and Japanese Patent No. 2999980. There is a heat insulation composite panel which is registered as a patent.
[0003]
[Conventional example 1]
FIG. 8 is a panel of Japanese Patent No. 2999980, in which three panels of molded cement plates having through holes are connected in parallel to the outer surface of a frame body composed of an upper frame, a lower frame, and both side frames. Fastened via a Z-clip, an interior board (gypsum board) is placed on the inner surface of the frame, and the cement board, frame, and interior board are hardened by injection filling foaming into the frame of rigid urethane foam. If it is integrated with a urethane foam heat insulating layer and used as a wall panel for steel structures, neither the spraying work of the heat insulating layer on the cement board nor the installation work of the interior surface material is required. This is an extremely useful composite panel that can significantly shorten the construction period.
[0004]
[Conventional example 2]
FIG. 9 is a panel disclosed in JP-A-5-171723, which is a formwork panel in which a reinforcing material is incorporated into a beaded polystyrene foam heat insulating material, and the heat insulating material integrated with the reinforcing material also used as an interior base. It is a formwork panel. (Product name: Statboard, manufactured by Iwakura Chemical Industry Co., Ltd.)
Specifically, it has a width of 910mm, lengths of 1820mm, 2100mm, 2400mm, 2700mm, 3000mm, various thicknesses of 45mm, 50mm, 65mm, 75mm, 100mm, special width 60mm, thickness 20mm As shown in FIG. 9 (B), the three reinforcing members (base materials) made of plastic are incorporated into the concrete formwork. This is a base material for interior surface material driving.
And a phase chip is given to both heat insulating material side surfaces, and a phase chip connection is carried out with an adjacent panel.
[0005]
[Problems to be solved by the invention]
However, in the heat insulation composite panel (Fig. 8) of the conventional example 1, when it is attached to the steel structure as a wall, it is suspended by a crane or the like. The side frame is indispensable for damming when injecting and foaming rigid urethane foam, but if the panel is built on a concrete frame, the side frame becomes a thermal bridge (heat bridge) and has a heat insulation function. In order to decrease, it was necessary to perform complicated thermal bridge prevention means (provided with a buffer in FIG. 8C) for the side frame.
[0006]
In addition, when foaming into the panel frame of urethane foam, forming a uniform heat insulation layer with uniform bubbles from the control surface of mixing two liquids of polymer and foaming agent, the uniform injection surface to a large panel area, etc. Was a cumbersome and skillful operation.
In addition, the integrated interior board (gypsum board) may be damaged or damaged during construction, especially if it is used for reinforced concrete structures, water spray before placing concrete or gypsum board Molding occurred on the gypsum board (interior board) due to water absorption due to contact with concrete such as floor slabs, etc., and there were problems with aesthetics, health problems such as atopy, and damage to storage clothes.
[0007]
Further, in the formwork panel of Conventional Example 2 (FIG. 9), the reinforcing material functions as a panel reinforcement at the time of the concrete formwork and the base material function of the interior board. When performing the wiring work, there is a problem of ditching to bury the electric wire by missing the heat insulating material.
[0008]
Therefore, the present applicant has succeeded in the development and proposed as Japanese Patent Application No. 2001-025142, and the heat insulation panel of the conventional example 1 (FIG. 8) is applied to a reinforced concrete building having a heat insulation composite panel as a single wall. ), The gypsum board (interior board) comes into contact with the floor slab, so that there is a problem that the mixed water of the concrete is absorbed to generate mold.
[0009]
In addition, the self-adhesive strength of the rigid urethane foam during foam solidification fixes the Z clip of the locking part to the cement plate frame, and the frame, cement plate, and interior plate are also fixed together in the composite panel. Since the effect of absorbing the interlayer displacement does not occur, there is a problem that cracks occur in the abutting portion of the interior board, particularly the gypsum board, in the event of an earthquake.
[0010]
As described above, the present invention includes a heat insulating composite panel (FIG. 8) of Conventional Example 1 (Japanese Patent No. 2999980) and a formwork panel (FIG. 9) of Conventional Example 2 (Japanese Patent Laid-Open No. 5-171723). It is possible to provide a new and extremely practical heat insulation composite panel that can solve or improve the problem and can be effectively used as the outer wall panel of a reinforced concrete building, and can be provided at a much lower cost. It is what.
[0011]
[Means for solving the problems and actions]
As shown in FIG. 1, for example, the heat insulating composite panel 1 for a book wall according to the present invention includes a cement board layer 2 having a ventilation layer 2h and upper and lower frames 4a and 4b made of steel materials attached to the upper and lower ends of the cement board layer 2. And a heat insulating composite panel 3 formed between the upper and lower frames 4a and 4b and formed on the cement plate layer 2, wherein the upper frame 4a, the lower frame 4b and the cement plate layer 2 are loosened by bolts 7a. The molded heat insulating layer 3 includes a plurality of embedded exposed base materials 5a and 5b including at least a longitudinal strip base material 5b provided with a longitudinal wiring groove 5G on the surface thereof, and Of the upper and lower frames, at least the inner surface of the upper frame 4a is covered with a fireproof covering material 6, and the molded heat insulating plate is layered and integrated with the cement plate layer 2.
[0012]
The upper frame 4a and the lower frame 4b may have any function as long as the cement plate layer 2 is fixed and the upper and lower ends of the panel are defined and the panel is attached to the building frame. If angle steel material of angle form is used, it is preferable because the cement board layer is fixed at the horizontal side 4H, the panel edge defining and panel mounting function can be provided at the rising side 4F, and sufficient mechanical strength can be exhibited. Steel is particularly preferred.
[0013]
Moreover, as the shaping | molding heat insulation layer 3, the synthetic resin foaming board which has water resistance and concrete adhesiveness is preferable, and it is a rigid urethane foam board typically.
Further, the “loose-hole fastening” by the bolt 7a between the cement board layer 2 and the frames 4a and 4b is performed when a large interlayer displacement stress acts between the cement board layer 2 and the upper frame 4a or the lower frame 4b. In order to generate a slip between the cement plate layer and the frame, as shown in FIG. 2A, the diameter d4 of the hole H4 of the cement plate and the holes H3 of the upper and lower frames 4a and 4b with respect to the diameter d7 of the bolt 7a. Both the diameters d3 of the bolts 7a may be loose holes, or only the upper and lower frame holes H3 may be loose holes, or only the cement plate holes H4 may be loose holes.
[0014]
Moreover, the meaning of “embedding exposure” includes a state in which the strip base materials 5a and 5b are completely embedded and only the surface is exposed, and a state in which the surface is exposed in a protruding form.
When the surface 5f of the strip base material 5a, 5b is flush with the heat insulating layer surface 3f, moisture-proofing the heat insulating layer surface 3f when attaching the interior surface material (interior surface plate) 27 to the base material 5a, 5b. When a sheet (not shown) is easily interposed and the strip base material surface 5f protrudes from the heat insulating layer surface 3f, a void layer is formed between the interior surface material 27 and the molded heat insulating layer 3, and the interior surface material. 27 and the sound insulation of the molded heat insulation layer 3 can be prevented, and the sound insulation is improved.
[0015]
Further, the base materials 5a and 5b embedded in the heat insulating layer are effective for tensioning with the screws of the interior face plate 27 such as gypsum board, and the wiring groove 5G enters the room before the interior face plate 27 is stretched. Therefore, only the base material 5b provided with the wiring groove 5G needs to be arranged in the vertical direction (panel vertical direction) on the heat insulating layer 3, but only the other interior faceplate 27 is stretched. 1 may be arranged in the vertical direction of FIG. 1 or arranged in the horizontal direction (panel crossing direction) in a form that does not interfere with the groove 5G of the strip base material 5b.
[0016]
Moreover, since the fireproof covering material 6 deals with a fire on the inner surface of the building on which the panel 1 is stretched, it is sufficient to apply only to the upper frame 4a portion for fire countermeasures. Even if covered, since there are few restrictions on the loose hole behavior of the bolt 7a, it is advantageous to cover and protect the lower frame 4b portion with the fireproof covering material 6 as well.
[0017]
In addition, the fire-resistant covering material 6 is advantageously a tape-like material of a general-purpose polymer material with a small thickness, and heat insulation, durability and safety (unlike fiber glass wool and rock wool, the material is scattered during work. In addition, there is no generation of toxic gas in the event of a fire, and it is good in terms of handling and hygiene safety), and it has good flame resistance, and can typically be easily cut with a knife and adhered. This is a fibroblock (trade name of Sekisui Chemical Co., Ltd.).
[0018]
Fibrock's 2mm-thick tape expands to about 30mm when fired, becomes a fireproof coating, can be made freely in width, and has an appropriate viscosity for adhesive use on the upper and lower frames 4a and 4b. Yes.
Therefore, since bending, cutting, and adhesion are easy, application to bolts and the like that are difficult to cover is also possible.
The fiblock fireproof covering 6 can be fixed to the angle steel frames 4a and 4b and the bolt 7a by self-adhesion.
[0019]
Moreover, in the heat insulation composite panel of this invention, when it uses as a book-wall panel of a reinforced concrete structure, since an interlayer deformation angle (earthquake-proof design standard: 1/2000 or less) is small, the cement board layer 2 and a frame The required seismic force can be exerted by loose hole form fastening with 4a, 4b, and combined with the use of a molded heat insulating material as the heat insulating layer, only the use of the upper frame 4a and the lower frame 4b made of steel. I can do it.
Moreover, the fireproof covering material 6 guarantees an action corresponding to the interlayer displacement due to loose hole form fastening, and also gives fire resistance to the inner surface of the panel.
[0020]
Therefore, unlike the conventional case, a strong and heavy frame is not required, and the filling and foaming management in the frame of the heat insulating layer is also unnecessary, so that a uniform heat insulating layer is provided, and also the earthquake resistance and fire resistance are provided. The heat insulating composite panel 1 having a sufficient function as a book wall panel for a reinforced concrete building can be provided at a significant cost reduction.
[0021]
In addition, the heat insulating composite panel 1 of the present invention is adopted as a book wall panel in a reinforced concrete wall-type structural building (Japanese Patent Application No. 2001-025142) that the applicant of the present invention has succeeded in development. Combined with the omission of the outer wall formwork and the cost reduction of the panel, it is possible to provide a reinforced concrete exterior heat insulating building with a revolutionary reduction in construction costs.
In addition, since the embedded base materials 5a and 5b exist in the molded heat insulating layer 3, the electrical wiring in the interior work can be easily and cleanly performed without causing ditching in the molded heat insulating layer. Tensioning can also be easily performed by the presence of the base materials 5a and 5b.
[0022]
Accordingly, the heat insulating composite panel 1 of the present invention is adopted as a book wall panel in a reinforced concrete wall-type structure building (Japanese Patent Application No. 2001-025142) that the applicant has previously developed successfully, so Combined with the omission of the outer wall formwork, the cost reduction of the panels, and the rational construction of the electrical wiring and the interior surface material, the reinforced concrete exterior heat insulation building dramatically reduces the construction cost. Will be available under.
[0023]
Moreover, in this heat insulating composite panel 1 for book walls, it is preferable that the ventilation layer is the upper and lower through holes 2h and the upper and lower frames 4a and 4b are angle steel materials.
In this case, loose hole type fastening between the cement board layer 2 and the upper and lower frames 4a and 4b is performed by inserting a flat nut 7b inside the through hole 2h as shown in FIG. 2 (A). It is only necessary to fasten with the bolt 7a from the horizontal side 4H side, and it can be carried out with good workability without being exposed to the panel outer surface.
In addition, an equilateral angle steel can be used for the upper frame 4a and the lower frame 4b. Moreover, since the ventilation layer is the upper and lower through-holes 2h, it is easy to connect the panel 1 up and down so that air can be conducted vertically.
[0024]
Also, the loose hole-type fastening between the cement plate layer 2 and the upper and lower frames 4a and 4b is, as shown in FIG. 2 (A), bolt insertion holes H4 drilled in the inner plate thickness portion Pt of the cement plate layer 2, And, it is preferable that the bolt 7a having a smaller diameter than the bolt insertion hole H3 on the horizontal side 4H of the corresponding frame 4a, 4b is fastened to the flat nut 7b in the through hole 2h from the horizontal side 4H side of the frame.
In this case, since both the cement board layer 2 and the frames 4a and 4b are loose holes, it is possible to slightly adjust the vertical and horizontal dimensions, the mounting work is easy, and the loose hole tightening that can cope with interlayer displacement is possible. Wear is obtained.
[0025]
Further, as shown in FIG. 2C, the loose hole has a bolt insertion hole H3 on the horizontal side 4H of the frames 4a and 4b having the same diameter as the bolt insertion hole H4 of the cement plate layer 2, and is a long hole in the vertical direction of the panel. Is preferred.
Interlayer displacement between the upper and lower frames 4a and 4b fixed to the building frame and the cement board layer 2 is absorbed by the cement board layer 2 rotating with respect to the housing, but the displacement is loose hole H3 of the bolt 7a. If the bolt insertion hole H3 of the upper and lower frames 4a, 4b has a loose hole diameter and is a long hole in the vertical direction, it is possible to cope with accidental interlayer displacement exceeding the seismic design value. It becomes.
[0026]
Moreover, in this invention panel 1, it is preferable that the cement board layer 2 is equipped with the recessed part 21 in the one side end, and the processus | protrusion 22 in the other side end.
In this case, as shown in FIG. 3C, the left and right connections between the panels 1 when forming the book wall can be smoothly performed by fitting the recesses 21 and the protrusions 22 with the non-combustible packing 23 interposed therebetween. Can be connected smoothly without gaps, so that workability and fire resistance are improved.
[0027]
In the panel 1 of the present invention, the cement plate layer 2 includes a plurality of cement plates 2P each having a recess 21 at one end and a protrusion 22 at the other end. The abutting parallel connection with the non-combustible packing 23 is preferable.
The incombustible packing 23 is preferably a double-sided adhesive type. For example, an SC blanket (trade name of Nippon Steel Chemical Co., Ltd.) can be used.
[0028]
The cement board as the outer wall material is cured in the autoclave chamber by moving the extruded body on the roller, but it is advantageous to have a narrower width from the production aspect, such as cracking due to impact and warping during curing. Therefore, it is advantageous to prepare a narrow cement board 2P advantageous in terms of cost and quality and connect a plurality of sheets to the required panel width 1W.
Moreover, as shown in FIG. 3 (B), since the abutting connection between the recess 21 and the projection 22 can be achieved through the non-combustible packing 23, the connecting portion (joint) 2G can also be connected without a gap, and the connection integration work is smooth. It can be implemented as if it had fire resistance like a single cement board.

[0030]
Therefore, it is easy to stick to the inner surface of the upper frame 4a and the lower frame 4b and to the bolt 7a and the washer 7c, and the metal portion of the panel 1 in contact with the molded heat insulating layer 3 is completely covered with the fireproof covering material 6. Since it can coat | cover, even when the shaping | molding heat insulation layer 3 burns by the fire inside a room, the deterioration by the fire of an up-and-down frame and a mounting bracket part can be suppressed to the minimum, and the fireproof function can be provided to the heat insulation composite panel 1.
[0031]
The cement board layer 2 and the molded heat insulating layer 3 are preferably laminated with a flexible elastic adhesive Ad.
The elastic adhesive may be a conventional one, and for example, an epoxy resin-based bond efflex (trade name of Konin Co., Ltd.) can be used.
When the cement board layer 2 and the molded heat insulating layer 3 are layered with an elastic adhesive, the cement board layer 2 that occurs within a minute reference interlayer deformation angle (earthquake resistant design standard: 1/2000) of a reinforced concrete building It is possible to cope with a slight interlayer displacement (slip between the cement board surface and the heat insulating layer surface) between the molded heat insulating layer 3 and the interior face plates such as gypsum boards that are finished and stretched on the surface of the molded heat insulating layer 3 Defects and cracks at the corners can be minimized.
[0032]
In the panel of the present invention, it is preferable that the heat insulating layer thickness 3T is larger than the upper and lower frame thickness 4T as shown in FIG.
In this case, in the panel of the present invention, the cement board layer 2 is provided with the ventilation layer 2h, so that it is lightweight with necessary strength as an outer wall, and the frame thickness 4T of the upper and lower frames 4a and 4b has sufficient strength. The insulation layer thickness can be smaller than 3T.
2A and 2B, the leading edge 4e of the rising edge 4F of the upper and lower frames is inside the heat insulating layer surface 3f, and the leading edge 4e is covered with the covering thickness 3r of the molded heat insulating layer 3. Therefore, direct contact with the building frame (floor slab S) on the upper and lower rising edges 4F can be avoided.
[0033]
Therefore, in the place where the mounting hardware M exists, a slight thermal bridge of the upper and lower frames 4a and 4b → the connecting pin Mp → the supporting plate Ms → the floor slab S is generated, but in the majority of the panel width, as shown in FIG. As described above, only the molded heat insulating layer 3 and the heat insulating material 25 interposed in the inter-panel joint 2G ′ are in contact with the floor slab S, and substantially the heat from the heat insulating composite panel 1 to the building frame (floor slab S). The bridge can be blocked.
[0034]
Further, in the upper and lower frames of the panel 1 of the present invention, the rising side 4F of the upper frame 4a is provided with mounting holes H1 and eye bolt fastening holes H2 at both ends, and the rising side 4F of the lower frame 4b is the mounting hole of the upper frame 4a. A mounting hole H1 is preferably provided at a position corresponding to H1.
If the eyebolt fastening holes H2 are drilled at both ends of the upper frame 4a, the panel 1 can be easily installed by attaching eyebolts (not shown) for lifting the panel 1.
[0035]
Further, the mounting holes H1 of the upper frame 4a and the lower frame 4B are for locking the upper and lower frames 4a, 4b to the mounting pins Mp of the mounting hardware M as shown in FIG. The mounting plate Ms of the mounting metal M may be screwed and fixed, and the mounting hole H1 of the upper and lower frames may be used as a pin hole for inserting the mounting pin Mp, or the mounting hole H1 of the upper frame 4a may be formed as shown in FIG. The mounting pins Mp may be screwed and fixed as screw holes, and the holes of the support plate Ms and the mounting holes H1 of the lower frame 4b may be used as pin holes.
Therefore, this invention panel 1 becomes easy to install as a book wall panel to a reinforced concrete structure building.

As shown, a grooved base material 5b is provided at the center of one molded heat insulating layer 3, a general base material 5a is provided on both sides, and when the panels 1 are arranged side by side, the base materials 5a and 5b are equally spaced. In addition, they are arranged in the mold in the vertical direction with a predetermined interval, and are embedded and integrated with the heat insulating layer surface 3f.
Since the grooved base material 5b is for electrical wiring, it is not necessary to arrange it on the entire panel. However, it functions as a stretched base material for the interior surface material, and rationalizes management in manufacturing the panel. Therefore, one hard urethane foam board is mixed and arranged.
[0040]
[Production of thermal insulation composite panel 1]
A cement board layer 2 in which three molding cement boards 2P are connected in parallel is placed on a molding press stand (not shown), and a plate thickness portion Pt inside the through holes 2h at both upper and lower ends of each cement board 2P. In addition, a bolt insertion hole H4 having a diameter d4 of 12 mm projecting as shown in FIG. 2 is denoted by a bolt insertion hole H3 on the horizontal side 4H of the upper and lower frames 4a, 4b, and the upper frame 4a and the lower frame 4b are connected to the cement plate 2 is mounted.
Then, a flat nut 7b is abutted from the inside of the through hole 2h, a bolt 7a having a diameter d7 of 10 mm is inserted from the horizontal side 4H side through a washer 7c, and fastened to the flat nut 7b, as shown in FIG. The frames 4a and 4b are fixed to the cement plate layer 2, the upper ends of each cement plate 2P are fixed to the upper frame 4a, and the lower ends are fixed to the lower frame 4b with bolts 7a.
[0041]
Next, a fire block (trade name) in the form of a double-sided adhesive tape having heat insulation, durability, and flame resistance is applied to the rising edge 4F, the horizontal edge 4H, the bolt 7a, and the washer 7c of the upper frame 4a and the lower frame 4b. The covering 6 is integrated by self-adhesion.
Then, a rigid urethane foam plate having a thickness of 75 mm in which synthetic resin base materials 5a and 5b having a width of 60 mm and a thickness of 20 mm are embedded and held in a single plane is provided in advance on the upper and lower surfaces of the upper frame 4a as shown in FIG. The cutout 3G is processed to the required dimensions in accordance with the shape of the lower frame 4b and the bolt 7a, and the phase cuts 26p and 26q (FIG. 3C) are applied to the left and right side surfaces at the center of the thickness. Rigid urethane foam board 3 is coated with base material 5a, 5b on the outer side with a flexible elastic epoxy resin adhesive, Bond Eflex (trade name of Konishi Co., Ltd.) on board layer 2. The (molded heat insulating layer 3) is integrated with the cement board layer 2.
In this case, the fireproof coating material 6 in contact with the upper frame 4a, the lower frame 4b, and the bolt 7a is integrated with the hard urethane foam plate by self-adhesive force.
[0042]
2A and 2B, the gap due to the notch 3G between the frame 4 and the rigid urethane foam board 3 is a sealed air layer if a paper tape is attached to the side edge (1s) of the composite panel. And the heat insulation effect does not decrease.
Accordingly, as shown in FIGS. 2 (A) and 2 (B), the obtained panel 1 has the fireproof covering material 6 interposed between the inner surfaces of the upper and lower frames 4a and 4b, the bolts 7a, and the molded heat insulating layer 3, and The leading edge 4e of the rising edge 4F of the upper and lower frames 4a, 4b is protected by the covering thickness 3r of the heat insulating layer, and a refractory heat insulating panel is formed that does not form a thermal bridge from the upper and lower frames 4a, 4b to the concrete frame.
[0043]
[Use of thermal insulation composite panel 1 (FIGS. 5 and 6)]
The heat insulating composite panel 1 obtained in the above-described embodiment is applied to a novel reinforced concrete exterior heat insulating building that the applicant previously proposed as Japanese Patent Application No. 2001-025142 using the heat insulating composite panel alone as a book wall. Is extremely effective.
That is, as shown in FIG. 5, the lower frame 4b of the heat insulating composite panel 1 is attached to the mounting pin Mp inserted into the support plate Ms of the mounting metal M fixed to the front end of the concrete floor slab S via the anchor portion Ma. It is inserted and locked through H1 (pin hole), and the panel lower surface Fb is attached below the floor slab surface Sf so as to prevent the rain water from entering the floor slab surface Sf from the panel lower end surface Fb.
[0044]
Further, in the upper part of the panel, the mounting pin Mp is screwed into the mounting hole H1 (screw hole) of the panel upper frame 4a and the support plate Ms is fitted to the mounting pin Mp. The part Ma is combined with the reinforcement in the formwork and fixed in the upper floor slab formwork, and the molding heat insulation layer 3 (hard urethane foam plate) at the upper end of the panel is solidified by placing concrete in the floor slab formwork. The upper frame 4a is fixed to the front end of the floor slab S in a state of being attached to the mounting metal M embedded in and integrated with the front end of the floor slab S via the mounting pin Mp. Form.
After the wall is formed only with the panel 1, the inner surface of the panel, that is, the molded heat insulating layer surface 3f, is washed and cleaned, and a predetermined interior face plate 27 (FIG. 7) such as a plaster board is interposed with a moisture-proof sheet (not shown). Then, it is stretched on the strip base material 5a, 5b.
[0045]
In this case, since the strip base materials 5a and 5b are embedded flush with the heat insulating layer surface 3f, even if the lower floor slab surface is uneven or the upper floor slab formwork is assembled, There is no interference between the materials 5a and 5b, and the lower and upper ends of the panel 1 can be easily attached.
And, when the concrete is placed in the upper floor slab formwork, the molded heat insulating layer 3 is large in concrete adhesion and low in water absorption, so that the upper inner surface of the panel 1 has no gap with the front end of the floor slab S, and Integrate firmly.
[0046]
Moreover, even if concrete mixing water flows out and adheres to the heat insulating layer surface 3f due to concrete placement, mold does not occur on the heat insulating layer surface 3f after the floor slab formwork dismantling.
Moreover, since the heat insulating layer surface 3f can be visually observed during interior construction, even if moisture adheres, the strip base materials 5a and 5b are embedded flush with each other, so that it is easy to wipe off the molded heat insulating layer. 3 and the fireproof covering material 6 do not generate mold, so even if an interior face plate such as a gypsum board is stretched through the base materials 5a and 5b, mold propagation contamination from the panel 1 surface to the interior face plate does not occur.
[0047]
FIG. 7 is an explanatory diagram of electrical wiring into the wall, wherein (A) is a schematic diagram of the interior side, (B) is a BB cross section of (A), and (C) is C of (A). FIG. 7 is a diagram showing a cross-section of the concrete floor slab S. In the concrete floor slab S, the concrete box 29 is placed in the form of the floor slab S by conventional wiring concrete box placement means as shown in FIG. Then, the concrete box 29 is embedded in the lower part of the front end of the floor slab, and the VVS wire 30 drawn from the concrete box 29 is suspended in the groove 5G of the grooved base material 5b, and as shown in FIG. And pull out the electric wire through the notch portion 5H of the base material 5b and connect it into the outlet integrated frame 28a, and fit the outlet integrated frame 28a into the outlet insertion hole H27 of the interior face plate 27 to attach the outlet decorative cover 28b. Interior surface 27 secured to the surface of.
[0048]
Therefore, in the book wall formed with the panel 1 of the embodiment of the present invention, the wiring from the concrete floor slab S to the indoor outlet 28 can be easily performed without damaging the molded heat insulating layer 3 and wiring. Construction can be streamlined.
Moreover, since the VVS line 30 becomes a wiring into the groove 5G at the center of the strip base material 5b, the VVS line is also inferior due to the reaction catalyst (amine) contained in the hard urethane foam plate (molded heat insulating layer). I do not receive it.
[0049]
In addition, as shown in FIG. 3C, the left and right connecting portions 2G between the panels 1 are also provided with the recesses 21 and the projections at the edge of the panel, like the joints 2G between the cement plates 2P in the panel 1 (FIG. 3B). The molded heat insulating layer 3 is preliminarily provided with phase defects 26q and 26p on both side surfaces of the heat insulating material to maintain the continuity of the molded heat insulating layer 3. In addition, the surface of the left and right connecting portion 2G between the panels is a backer as shown in FIG. 3C in the exterior finish after the panel is stretched together with the joint 2G between the cement plates 2P in the panel 1 (FIG. 3B). The joint is finished by a fireproof sealing 24 through 24 '.
[0050]
Further, the upper and lower connecting portions 2G ′ of the panels 1 are also placed on the upper frame 4a in such a manner that the heat insulating material 25 is sandwiched between the upper and lower panels as shown in FIG. In Pt, the fireproof sheet 23 'is interposed and closed by the sealing 24, and in the front side plate thickness portion Pt, the exterior finish is ensured by the fireproof sealing 24 through the backer 24' to ensure the air conduction a of the through hole 2h and the joint finish. To do.
[0051]
Therefore, the outer wall of the book wall formed by the heat insulating composite panel 1 according to the embodiment of the present invention can prevent a thermal bridge from the panel 1 to the concrete frame and can rationally carry out electrical wiring.
And, on the fireproof side, the cement board layer 2 and the nonflammable packing 23 and the fireproof sheet 23 'of the connecting part (joint) cope with fire outside the building, and fireproof from the indoor side against fire. The material 6 has fire resistance to be dealt with, and on the seismic surface, bolts in the form of loose holes between the cement plate 2P and the upper and lower frames 4a and 4b, and elastic bonding between the cement plate layer 2 and the molded heat insulating layer 3 The layering by the agent absorbs the interlaminar displacement between the cement board layer 2 and the molded insulation layer 3 caused by the shaking of the building during earthquakes and strong winds, and cracks in the finished interior board (gypsum board) on the cement board layer 2 and the insulation layer It becomes the thing which can suppress a crack and a fireproof, earthquake-resistant outer wall.
Moreover, it is possible to finish the interior surface without fear of mold contamination.
[0052]
In addition, since the cement plate 2P and the upper and lower frames 4a and 4b are attached with a Z clip as shown in FIG. 8 in the conventional example 1, the panel is mounted so as to prevent the cement plate from falling off when the panel is installed. It was necessary to use the mounting piece arranged for each cement plate and attach it to the concrete frame with the mounting hardware corresponding to each cement plate. In the present invention, the cement plate is attached to the upper and lower frames 4a and 4b with bolts 7a. Even if three cement plates 2P are used in one panel 1 as shown in the form examples (FIGS. 4 and 6), the panel 1 can be mounted on the concrete frame with two mounting hardware on both sides of the panel. It becomes.
Therefore, it is possible to reduce the number of mounting hardware M used, reduce the cost of mounting hardware, and facilitate panel 1 mounting work. By reducing the number of mounting hardware M, heat from the panel 1 to the concrete frame can be achieved. Bridge action can also be reduced.
[0053]
Moreover, the manufacturing cost of the heat insulation composite panel 1 was significantly reduced by using only the upper frame 4a and the lower frame 4b as the panel frame body, and forming the heat insulation layer 3 as a molded heat insulation layer, and a reinforced concrete building. In addition, the non-bearing wall is made of a composite wall with only the heat-insulating composite panel 1, and the concrete frame work for the non-bearing wall is not required when forming the outer wall. Buildings can be provided with significant reduction in construction costs.
[0054]
[Others]
The strip base materials 5a and 5b are arranged in the vertical direction with respect to the panel in the embodiment (FIG. 1), but may be arranged in the horizontal direction.
However, only the base material 5b having the wiring groove 5G needs to be arranged in the vertical direction, and the other base material 5a should be arranged so as not to interfere with the groove 5G.
Further, in the grooved base material 5b, in the embodiment (FIG. 1C), the wiring groove 5G is disposed at the center portion. However, if the wiring groove 5G is disposed at the end portion, the strip base material is provided. The work of driving screws and nails of the interior faceplate onto the material 5b is facilitated.
In this case, what is necessary is just to select a material for a heat insulation layer and an electric wire coating material so that deterioration of an electric wire coating material may not arise by contact with a heat insulation layer.
[0055]
When the base material surface 5f is protruded from the heat insulating layer surface 3f in the vertical arrangement, the upper ends of the base materials 5a and 5b are set at a height that does not interfere with the floor slab type work, that is, below the lower surface of the floor slab S, The lower ends of the base materials 5a and 5b are preferably higher than the floor slab surface Sf so as to cope with unevenness of the floor slab surface.
Moreover, if the thing which gave moisture-proof processing to the shaping | molding heat insulation board beforehand, such as the heat insulation board which laminated the surface of the hard urethane foam with the moisture proof sheet, as the shaping | molding heat insulation layer 3, prevention of the internal dew condensation of a panel will become more reliable. .
[0056]
In addition, the interlaminar deformation angle in the seismic design standard is 1/2000 or less for reinforced concrete wall-type structures, and 1/200 or less for steel frames and reinforced concrete ramen structures. The panel of the present invention is for reinforced concrete structures with a standard length of 2880 mm. Therefore, the loose hole fastening between the cement plate 2P and the upper and lower frames 4a and 4b is performed when the loose hole H4 of the cement plate 2P and the loose hole H3 of the upper and lower frames are 12 mm in diameter and the fastening bolt 7a is 10 mm in diameter. The function of absorbing inter-layer displacement within the seismic design standard is sufficiently achieved, but the shape and size of the loose holes H3 and H4 can be appropriately determined from the surface of absorbing larger inter-layer displacement or adjusting the fastening position. good.
[0057]
In the embodiment, a flexible elastic epoxy resin-based adhesive is applied as an adhesive between the cement board layer 2 and the molded heat insulating layer 3, but a normal synthetic resin molded board as the molded heat insulating layer 3 is not eroded. Even if the adhesive is used, the panel 1 can achieve the purpose of absorbing the interlayer displacement within the interlayer deformation angle (1/2000) of the seismic design standard by loose hole fastening of the frames 4a and 4b and the cement board layer 2. .
[0058]
【The invention's effect】
The heat insulating composite panel 1 of the present invention is manufactured by assembling the cement plate 2P as a molded product, the heat insulating layer 3 as a molded product, and the upper and lower frames 4a and 4b as molded products. No need for a strong and heavy frame to endure, and no need to manage filling and foaming inside the frame of the heat insulation layer, so it can be reduced in weight and manufactured at low cost by forming a heat insulation layer with a uniform heat insulation function. I can do it.
[0059]
Furthermore, the cement plate layer is fastened to the frames 4a and 4b in the form of a loose hole so as to be able to cope with interlayer displacement, and fire from the indoor side by the inner surface coating of the upper frame 4a with the fireproof covering material 6, and A panel having sufficient functions as a book wall panel of a reinforced concrete structure having fire resistance from the outside by the cement board layer 2 capable of handling fires.
[0060]
In addition, since the molded heat insulating layer is layered on the cement board layer 2 with a flexible elastic adhesive Ad, it is possible to cope with the interlayer displacement between the molded heat insulating layer 3 and the cement board layer 2, and in the event of an earthquake, Not only the cracks and defects of the cement board layer 2 as a material can be suppressed, but also the defects of the interior surface material stretched on the heat insulating layer can be minimized.
In addition, since the molded heat insulating layer 3 exposes and exposes the strip base materials 5a and 5b, the interior surface material can be easily stretched after the outer wall is formed on the panel, and due to the presence of the base material 5b provided with the grooves 5G, The electrical wiring work inside the panel can be easily performed without causing any defects in the heat insulation layer.
[0061]
And since the shaping | molding heat insulation layer 3 is water-resistant and covers the whole panel inner surface, mold | contamination contamination does not generate | occur | produce in an interior surface material.
Further, since the leading edge 4e of the rising edge 4F of the upper and lower frames 4a and 4b is located on the inner side through the covering thickness 3r from the surface 3f of the molded heat insulating material, the upper and lower frames 4a and 4b are in contact with the building frame. In combination with the absence of thermal bridge (heat bridge) and the absence of thermal bridge action from the side frame as in the conventional panel, the panel of the present invention is extremely effective in preventing thermal bridge action. Provide an outer wall.
