Description

【０００１】
【発明の属する技術分野】
この発明は、例えば，住宅，事務所，倉庫等の建築物の外壁や内壁等を構成するサンドイッチ積層板の接合構造に関する。
【０００２】
【従来の技術】
住宅，事務所，倉庫等の建築物において、断熱及び遮音効果の優れた外壁や内壁等を構成するためにサンドイッチ積層板を使用することが普及している。このサンドイッチ積層板は，発泡ウレタンや発泡フェノールフォーム材等の合成樹脂発泡材を素材とする断熱材を繊維強化プラスチックからなる複合板によってサンドイッチした構造であり，断熱材の両側面に接着剤によって複合板を接着して一体構造としている。
【０００３】
このように構成されたサンドイッチ積層板（以下，積層板という）を多数枚用意し，積層板相互を接合して建築物の外壁や内壁を構成する場合，積層板の上下左右の端面は断熱材が露出しているために、積層板の端面を閉塞した状態で積層板相互を接合する必要がある。
【０００４】
そこで、従来においては，例えば，外壁の場合，図１１及び図１２に示すように構成している。すなわち，図１１は，隣合う一方の積層板１ａの端部における複合板２ａ、２ｂ間に断熱材３の端面を覆う雌型継手４を設け，他方の積層板１ｂの端部における複合板２ａ、２ｂ間に断熱材３の端面を覆う雄形継手５を設ける。雌型継手４は前面に凹部６を有し，両側面は接着剤７によって複合板２ａ、２ｂの内面に接着されている。雄型継手５は前面に凹部６と嵌合する凸部８を有し，両側面は接着剤７によって複合板２ａ、２ｂの内面に接着されている。
【０００５】
そして，雌型継手４と雄型継手５との間に耐火パッキング９を介在した状態で，凹部６と凸部８とを嵌合した上，特に外面（屋外）における複合板２ａ，２ａ間の隙間をシーリング材１０によって水密にシールしている。
【０００６】
図１２は，隣合う一方の積層板１ａの端部における複合板２ａ、２ｂ間に断熱材３の端面を覆うＬ形継手１２を設け，他方の積層板１ｂの端部における複合板２ａ、２ｂ間に断熱材３の端面を覆う逆Ｌ形継手１３を設ける。Ｌ形継手１２及び逆Ｌ形継手１３は前面に段差部１２ａ，１３ａを有し，両側面は接着剤７によって複合板２ａ、２ｂの内面に接着されている。
【０００７】
そして，Ｌ形継手１２と逆Ｌ形継手１３との間に耐火パッキング９を介在した状態で，互いに段差部１２ａ，１３ａの高所と低所を対向した上，特に外面（屋外）における複合板２ａ，２ａ間の隙間をシーリング材１０によって水密にシールしている。
【０００８】
【発明が解決しようとする課題】
しかしながら，前述のように構成された積層板の接合構造は，接着剤によって継手を複合板の内面に接着している。従って，接着剤が経時変化によって劣化すると、複合板と継手の接着部分が剥離し，複合板に落下する虞がある。また，火災等が発生した場合，火炎が断熱材まで侵入し，断熱材が溶融して耐火性能を損なう可能性がある。
【０００９】
この発明は、前記事情に着目してなされたもので、その目的とするところは、積層板と継手とを強固に結合でき，接着剤が劣化しても複合板と継手との結合構造が確保でき，複合板の落下，火災時における火炎の侵入を未然に防止できるサンドイッチ積層板の接合構造を提供することにある。
【００１０】
【課題を解決するための手段】
この発明は前記目的を達成するために、請求項１は、断熱材を繊維強化プラスチックなどの複合板によってサンドイッチしたサンドイッチ積層板の端面相互を継手を介して接合するサンドイッチ積層板の接合構造において，前記継手は，前記サンドイッチ積層板の端面にその長手方向に亘って設けられ，前記断熱材の端面を覆うとともに，断面が略Ｌ字状で前面側に段差部を有する継手主体部と，この継手主体部の長手方向に沿う両側部に背面側に突出して設けられ，前記複合板の端部と凹凸係合する係合部とから構成され，隣合う前記サンドイッチ積層板における継手の段差部の高所と低所を互いに対向させ，かつ両継手間にパッキン部材を介在して前記サンドイッチ積層板相互を接合したことを特徴とする。
【００１１】
請求項２は，請求項１の前記係合部は，前記複合板の端部に設けられ端面に開口する差込み穴と，前記継手主体部に設けられ前記差込み穴に差込み係合される差込み片とからなることを特徴とする。
【００１２】
請求項３は，請求項１の前記係合部は，前記複合板の端部に設けられ端面に開口する凹部と，前記継手主体部に設けられ前記凹部に係合される筒部とからなることを特徴とする。
【００１３】
請求項４は，請求項１の前記サンドイッチ積層板の両複合板の互いに対向する内面には互いに当接または係合するリブが一体に設けられていることを特徴とする。
【００１４】
請求項５は、請求項２の前記差込み穴に対向する複合板にはボルト穴を有し，前記継手主体部の差込み片には前記ボルト穴に対向するナットが埋設され，ボルトを複合板の外側からナットに螺合可能であることを特徴とする。
【００１５】
前記構成によれば，積層板に設けた継手に段差部が設けられているため、積層板における継手の段差部の高所と低所を互いに対向させる。そして，両継手間にパッキン部材を介在するすることにより，複数枚の積層板を上下方向及び左右方向に接合して外壁，内壁等を構成することができる。
【００１６】
さらに、複合板の端部の差込み穴に継手の差込み片が差込まれ，断熱材は継手の継手主体部によって覆われ，端部からはみ出ることはなく，複合板の間隔は差込み片によって保たれるため，複合板が熱的影響を受けても変化することはなく，変形及び剥離を防止できる。
【００１７】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。
【００１８】
図１〜図４は第１の実施形態を示し，図１は建築物の外壁や内壁を構成する壁体を示す斜視図，図２は図１のａ−ａ線に沿う断面図，図３はサンドイッチ積層板の斜視図，図４は図１のｂ−ｂ線に沿う断面図である。この発明のサンドイッチ積層板（以下，積層板２１という）は，例えば幅が２３〜４５ｃｍ，長さが１８０ｃｍ，厚さが５ｃｍの長方形状の板状体であり，図１に示すように，多数枚の積層板２１を縦方向および横方向に接合することにより、壁体２０を構成するものである。
【００１９】
各積層板２１は同一形状で，図２に示すように，積層板２１の下端部と上端部とが後述するように逆段差で，上端側の第１の積層板２１ａと下端側の第２の積層板２１ｂが噛み合って接合するようになっている。また，隣り合う左右の第１の積層板２１ａ同士及び第２の積層板２１ｂ同士は図４に示すように，左右の端部同士が噛み合って接合するようになっている。すなわち，多数枚の積層板２１を互いに上下方向及び左右方向に配置して積層板２１相互を接合して建築物の外壁や内壁等の壁体２０を構成できる。
【００２０】
第１の積層板２１ａと第２の積層板２１ｂは基本的には同一構造であるため，図２及び図３に基づいて、その一方（第１の積層板２１ａ）について説明すると、樹脂発泡材を素材とする断熱材２２の両側面に繊維強化プラスチック板からなる複合板２３ａ、２３ｂが接着された厚さが約５ｃｍのサンドイッチ構造である。
【００２１】
複合板２３ａの下端部は複合板２３ｂの端部よりも延長して複合板２３ａ、２３ｂの端部に段差２３ｃが形成されているとともに、両複合板２３ａ、２３ｂの端部には板の全長に亘って肉厚部２４が形成されている。そして，この肉厚部２４には端面に開口する差込み穴２５が肉厚部２４の全長に亘って設けられている。
【００２２】
複合板２３ａ、２３ｂの下端部における段差２３ｃには継手２６が設けられている。この継手２６は合成樹脂あるいはアルミニウム材料からなる引抜き成形品で，第１の積層板２１ａの端面にその長手方向に亘って設けられている。
【００２３】
この継手２６は，断熱材２２の端面を覆う継手主体部２７が段差２３ｃに倣って横断面が略Ｌ字状に形成され，前面側に段差部２７ａを有している。さらに，継手主体部２７の長手方向に沿う両側部には背面側に突出する差込み片２８ａ、２８ｂが一体に設けられている。そして、一方の差込み片２８ａは複合板２３ａの差込み穴２５に差込まれ，他方の差込み片２８ｂは複合板２３ｂの差込み穴２５に差込まれ，複合板２３ａ，２３ｂと継手２６とを凹凸係合する係合部２９を構成している。
【００２４】
さらに、差込み穴２５の内面と差込み片２８ａ，２８ｂの外面との間には接着剤３０が塗布され，複合板２３ａ，２３ｂと継手２６とは接着剤３０によって結合されている。従って，断熱材２２は継手２６の継手主体部２７によって覆われ，端部からはみ出ることはなく，複合板２３ａ、２３ｂの間隔は差込み片２８ａ，２８ｂによって保たれるため，複合板２３ａ、２３ｂが熱的影響を受けても変化することはなく，変形及び剥離を防止できる。
【００２５】
また，第１の積層板２１ａの長手方向の一端部には凹部１５ａを有する断面がＨ形の第１の継手１５が設けられ，他端部には凹部１５ａに係合する凸部１６ａを有する第２の継手１６が設けられている。第１及び第２の継手１５，１６は第１の複合板２１ａの差込み穴２５と同様の差込み穴１７に差込まれており、複合板２３ａ、２３ｂを結合すると同時に断熱材２２のはみ出しを防止している。
【００２６】
次に，第１と第２の積層板２１ａ，２１ｂを上下に接合する構造及び第１の積層板２１ａ相互を左右に接合する構造について説明する。
【００２７】
第１と第２の積層板２１ａ，２１ｂは基本構造が同一で，継手２６の段差部２７ａが逆段差に形成されているため、第１と第２の積層板２１ａ，２１ｂにおける継手２６の段差部２７ａの高所と低所を互いに対向させる。そして，両継手２６間にパッキン部材としての耐火パッキン３１を介在する。
【００２８】
この耐火パッキン３１は，例えばケイ酸カルシウム，ロックウール，シリコンゴム等からなり，隣り合う継手２６相互間に一定の間隔を保つように断面が矩形状のブロックで，継手２６の全長に亘って設けられている。さらに，外壁の外側（屋外）となる第１の複合板２３ａ相互間の隙間はシーリング材３３によって水密にシールされる。
【００２９】
また，左右に隣り合う第１の積層板２１ａ相互，いわゆる縦目地部は，第１の積層板２１ａの長手方向の一端部における第１の継手１５の凹部１５ａに、第１の積層板２１ａの他端部の第２の継手１６の凸部１６ａを係合する。このとき，第１の継手１５と第２の継手１６との間にパッキン部材としての耐火パッキン３１を介在するとともに，外壁の外側（屋外）となる第１の複合板２３ａ相互間の隙間はシーリング材３３によって水密にシールされる。
【００３０】
このように構成されたサンドイッチ積層板の接合構造は，積層板を縦方向に並べ，その上下で結合するとともに，横方向に並べ左右で接合することにより、建造物の外壁，内壁及び間仕切り等の壁体２０を構成することができる。しかも，第１と第２の積層板２１ａ，２１ｂとを接合する横目地部は，継手２６相互が逆段差によって係合し、左右に隣り合う第１の積層板２１ａ相互を接合する縦目地部は，第１の継手１５の凹部１５ａに、第２の継手１６の凸部１６ａが凹凸係合するため，強固に結合できることは勿論，組立て作業時の積層板交互の位置決めが容易となり，作業性を向上できる。
【００３１】
図５は第２の実施形態を示し，第１の実施形態と同一構成部分は同一番号を付して説明を省略する。本実施形態の複合板２３ａの端部は複合板２３ｂの端部よりも延長して複合板２３ａ、２３ｂの端部に段差２３ｃが形成されているとともに、複合板２３ａの端部には大形凹部３４が設けられ，複合板２３ｂの端部には小形凹部３５が板の全長に亘って形成されている。そして，大形凹部３４及び小形凹部３５の底部によって断熱材２２を覆っているとともに，内壁には内部に向って突出する突条部３６、３７がそれぞれ設けられ、これも板の全長に亘って形成されている。
【００３２】
複合板２３ａ、２３ｂの端部における段差２３ｃには継手３８が設けられている。この継手３８は合成樹脂あるいはアルミニウム材料からなる引抜き成形品で，第１の積層板２１ａの端面にその長手方向に亘って設けられている。
【００３３】
この継手２６は，大形凹部３４及び小形凹部３５に嵌合する大形筒部３９と小形筒部４０が連結部４１によって一体に連結されている。そして，継手３８が段差２３ｃに倣って横断面が略Ｌ字状に形成され，前面側に段差部３８ａを有している。さらに，大形筒部３９と小形筒部４０の外壁には大形凹部３４及び小形凹部３５の突条部３６，３７と係合する凹条部４３，４４が設けられている。従って，複合板２３ａ，２３ｂと継手３８とを凹凸係合する係合部４５を構成している。
【００３４】
さらに、大形凹部３４及び小形凹部３５に嵌合する大形筒部３９と小形筒部４０は接着剤３０によって結合されている。従って，断熱材２２は継手３８の大形凹部３４及び小形凹部３５によって覆われ，端部からはみ出ることはなく，複合板２３ａ、２３ｂの間隔は大形筒部３９と小形筒部４０によって保たれるため，複合板２３ａ、２３ｂが熱的影響を受けても変化することはなく，変形及び剥離を防止できる。また，突条部３６，３７と凹条部４３、４４が係合することにより，継手３８，複合板２３ａ，２３ｂの結合が一層確実となる。
【００３５】
次に，第１と第２の積層板２１ａ，２１ｂを接合する構造について説明すると，第１と第２の積層板２１ａ，２１ｂは基本構造が同一で，継手３８の段差部３８ａが逆段差に形成されているため、第１と第２の積層板２１ａ，２１ｂにおける継手３８の段差部３８ａの高所と低所を互いに対向させる。そして，両継手３８間にパッキン部材としての耐火パッキン３１を介在する。さらに，外壁の外側（屋外）となる第１の複合板２３ａ相互間の隙間はシーリング材３３によって水密にシールされる。
【００３６】
図６は第３の実施形態を示し，第１の実施形態と同一構成部分は同一番号を付して説明を省略する。本実施形態は、断熱材２２の両側面に設けられた複合板２３ａ、２３ｂを中間部位で結合する構造を示す。（Ａ）は複合板２３ａの内面に凸部４６ａを有するリブ４６を設け，複合板２３ｂの内面に凸部４６ａと嵌合する凹部４７ａを有するリブ４７を設けて結合したものである。
【００３７】
（Ｂ）は複合板２３ａの内面に係合凸部４８ａを有するリブ４８を設け，複合板２３ｂの内面に係合凸部４８ａと嵌合する係合凹部４９ａを有するリブ４９を設けて結合したものである。
【００３８】
（Ｃ）は複合板２３ａの内面に突き当て部５０ａを有するリブ５０を設け，複合板２３ｂの内面に突き当て部５０ａと当接する受け部５１ａを有するリブ５１を設けて結合したものである。
【００３９】
これらのリブは，複合板２３ａ、２３ｂを引抜き成形法によって長手方向に連続して形成することができ，複合板２３ａ、２３ｂの間隔を一定に保ち，変形を防止することができる。
【００４０】
図７は第４の実施形態を示し，第１の実施形態と同一構成部分は同一番号を付して説明を省略する。本実施形態は、第１の実施形態における複合板２３ａの肉厚部２４に設けた差込み穴２５を深く形成し，この差込み穴２５の奥部に鉄またはステンレス等の金属板５２を差込んだ構造である。このように構成することにより，金属板５２が補強部材となり、複合板２３ａの強度アップを図るとともに、複合板２３ａを建物の構造体に取り付けたり，複合板２３ａに何らかの付加物を取り付けたりする際の受け金具として利用することができる。
【００４１】
図８は第５の実施形態を示し，第１の実施形態と同一構成部分は同一番号を付して説明を省略する。本実施形態は、第１の実施形態における第１の複合板２１ａの長手方向の両端部において結合した，いわゆる縦目地部において，壁体２０を構造体５４に固定する構造を示す。
【００４２】
第１の複合板２１ａの長手方向の両端部における複合板２３ｂにはそれぞれＺクリップ５５がボルト５６によって固定されている。そして，第１の複合板２１ａ相互の縦目地部はパッキン５７を介して構造体５４に接合され，この構造体５４に対してＺクリップ５５によって第１の複合板２１ａが固定されている。従って，壁体２０を構造体５４に対して簡単にしかも強固に固定できる。
【００４３】
図９は第４の実施形態の変形例を示し，複合板２３ａの肉厚部２４に設けた差込み穴２５に差込まれる差込み片２８ａにナット５３を埋設したものである。このように構成することにより，ナット５３を締付け部材とすることができる。すなわち，Ｚクリップ５５をボルト５６によってナット５３に固定したのち、Ｚクリップ５５を構造体５４に係合することにより，壁体２０を構造体５４に対して簡単にしかも強固に固定できる。また，本変形例においては，ナット５３を差込み片２８ａに埋設することにより、ナット５３が正確に位置決めされ，ボルト５６の締付け時にも脱落の虞はなく，組立て作業性を向上できる。
【００４４】
図１０は第６の実施形態を示し，第１の実施形態と同一構成部分は同一番号を付して説明を省略する。本実施形態は、積層板２１を上下方向に結合して構成した外壁または内壁の側端部における封止構造であって，複合板２３ａ、２３の端部間に断面がコ字状の端部覆い板５６を嵌合し、この端部覆い板５６によって断熱材２２を覆うようにしたものである。また，同様の端部覆い板５６によって複合板２３ａ，２３ｂの上端部における開口を閉塞することも可能である。
【００４５】
なお，前記各実施形態においては，複数枚の積層板を上下，左右に接合して外壁や内壁を構成する場合について説明したが，建築物のコーナ部においては，通常，出隅または入隅のコーナパネルが使用されるが，コーナパネルと前述した積層板との結合においても前述した実施形態と同様の結合構造によって結合できる。
【００４６】
【発明の効果】
以上説明したように、この発明によれば，サンドイッチ積層板の端面に断熱材の端面を覆う継手主体部を設け，この継手主体部の両側部に複合板の端部と凹凸係合する係合部を設けたから，サンドイッチ積層板を構成する複合板の間隔を一定に保ち，熱的影響を受けても、また接着剤が劣化しても，変形したり，剥離することはなく，建築物の外壁や内壁および間仕切り等に好適する。
【００４７】
また、断熱材を継手によって完全に覆うことにより，火災時における火炎の侵入により断熱材が溶融することはなく，複合板の落下事故を未然に防止できるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a joining structure of sandwich laminates constituting outer walls and inner walls of buildings such as houses, offices, and warehouses.
[0002]
[Prior art]
In buildings such as houses, offices, and warehouses, it is widespread that sandwich laminates are used to form outer walls and inner walls with excellent heat insulation and sound insulation effects. This sandwich laminate has a structure in which a heat insulating material made of a synthetic resin foam material such as foamed urethane or foamed phenol foam material is sandwiched by composite plates made of fiber reinforced plastic, and is combined with adhesive on both sides of the heat insulating material. The plates are bonded to form an integral structure.
[0003]
When a large number of sandwich laminate plates (hereinafter referred to as laminate plates) constructed in this way are prepared and the laminate plates are joined together to form the outer and inner walls of a building, the top, bottom, left, and right end faces of the laminate are heat insulating materials. Therefore, it is necessary to join the laminates with the end faces of the laminates closed.
[0004]
Therefore, in the prior art, for example, in the case of an outer wall, it is configured as shown in FIGS. That is, in FIG. 11, a female joint 4 that covers the end face of the heat insulating material 3 is provided between the composite plates 2a and 2b at the end of one adjacent laminated plate 1a, and the composite plate 2a at the end of the other laminated plate 1b. A male joint 5 covering the end face of the heat insulating material 3 is provided between 2b. The female joint 4 has a recess 6 on the front surface, and both side surfaces are bonded to the inner surfaces of the composite plates 2a and 2b by an adhesive 7. The male joint 5 has a convex portion 8 fitted to the concave portion 6 on the front surface, and both side surfaces are bonded to the inner surfaces of the composite plates 2 a and 2 b by an adhesive 7.
[0005]
Then, with the fireproof packing 9 interposed between the female joint 4 and the male joint 5, the concave portion 6 and the convex portion 8 are fitted together, and in particular between the composite plates 2a and 2a on the outer surface (outdoor). The gap is sealed in a watertight manner by the sealing material 10.
[0006]
In FIG. 12, an L-shaped joint 12 that covers the end face of the heat insulating material 3 is provided between the composite plates 2a and 2b at the end of one adjacent laminate 1a, and the composite plates 2a and 2b at the end of the other laminate 1b. An inverted L-shaped joint 13 that covers the end face of the heat insulating material 3 is provided therebetween. The L-shaped joint 12 and the inverted L-shaped joint 13 have stepped portions 12 a and 13 a on the front surface, and both side surfaces are bonded to the inner surfaces of the composite plates 2 a and 2 b with an adhesive 7.
[0007]
Then, with the fireproof packing 9 interposed between the L-shaped joint 12 and the inverted L-shaped joint 13, the high and low portions of the stepped portions 12 a and 13 a are opposed to each other, and in particular, the composite plate on the outer surface (outdoor) The gap between 2a and 2a is watertightly sealed by the sealing material 10.
[0008]
[Problems to be solved by the invention]
However, in the laminated plate joining structure configured as described above, the joint is bonded to the inner surface of the composite plate with an adhesive. Therefore, when the adhesive deteriorates with time, there is a possibility that the bonded portion of the composite plate and the joint peels off and falls to the composite plate. In addition, in the event of a fire or the like, the flame may penetrate into the heat insulating material and the heat insulating material may melt and impair fire resistance.
[0009]
The present invention has been made paying attention to the above circumstances, and the purpose thereof is to firmly bond the laminated plate and the joint, and to secure a coupling structure between the composite plate and the joint even if the adhesive deteriorates. Another object of the present invention is to provide a sandwich laminate joining structure that can prevent the composite plate from falling and the intrusion of flames in the event of a fire.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a sandwich laminate joining structure in which end faces of a sandwich laminate in which a heat insulating material is sandwiched between composite plates such as fiber reinforced plastics are joined together via a joint. The joint is provided on the end face of the sandwich laminate plate in the longitudinal direction, covers the end face of the heat insulating material, has a substantially L-shaped cross section, and has a joint main part having a step portion on the front side, and the joint Protruding to the back side on both sides along the longitudinal direction of the main body, and composed of an engagement portion engaging with the concave and convex portions of the composite plate, the height of the step portion of the joint in the adjacent sandwich laminate The sandwich laminates are joined to each other with a place and a low part facing each other, and a packing member interposed between both joints.
[0011]
According to a second aspect of the present invention, the engaging portion according to the first aspect includes an insertion hole provided at an end portion of the composite plate and opening in an end surface, and an insertion piece provided in the joint main body portion and inserted into the insertion hole. It is characterized by the following.
[0012]

It is characterized by that.
[0013]
According to a fourth aspect of the present invention, ribs that are in contact with or engage with each other are integrally formed on the inner surfaces of the composite plates of the sandwich laminate according to the first aspect of the present invention.
[0014]
According to a fifth aspect of the present invention, the composite plate opposed to the insertion hole of claim 2 has a bolt hole, and the insertion piece of the joint main part is embedded with a nut facing the bolt hole, and the bolt is attached to the composite plate. It can be screwed onto the nut from the outside.
[0015]
According to the said structure, since the level | step-difference part is provided in the joint provided in the laminated board, the high part and low part of the level | step-difference part of the joint in a laminated board are mutually opposed. And by interposing a packing member between both joints, an outer wall, an inner wall, etc. can be constituted by joining a plurality of laminated boards in the up-and-down direction and the left-and-right direction.
