Description

【０００１】
【発明の属する技術分野】
本発明は、内外壁、屋根、床などに主に使用される複合パネルに関し、詳しくは、サンドイッチパネルと無機質系表面化粧材とを接合する技術に関するものである。
【０００２】
【従来の技術】
従来より、内外壁、屋根、床などには、軽量で断熱性及び耐火性に優れたＡＬＣパネルが用いられており、このＡＬＣパネルの外観意匠性の改善のために、その表面にタイルを貼り付けるようにしているが、このようなタイル仕上げではその耐久性に問題があった。
【０００３】
そこで、耐久性を改善するために、図６に示すように、ＡＬＣパネル２０の表面に、板状の無機質系表面化粧材６を接着剤２１或いは両面テープ等を用いて全面接着するようにした複合パネルが知られている。
【０００４】
また、最近では、ＡＬＣパネルに代えて、一対の金属外皮間に断熱材が介装されたサンドイッチパネルを内外壁、屋根、床などに用いることが主流となりつつあり、このサンドイッチパネルの外表面に板状の無機質系表面化粧材６を接着した複合パネルが多く採用されつつある。
【０００５】
【発明が解決しようとする課題】
ところが、無機質系表面化粧材６とサンドイッチパネルとを組み合わせた複合パネルにあっては、無機質系表面化粧材６をサンドイッチパネルの一方の金属外皮に接着する方法として、従来のような全面接着方式を使用すると、金属材料と無機質材料との間には熱膨張率の差があるため、この熱膨張率の差による応力が無機質系表面化粧材６に加わり、無機質系表面化粧材６にクラック又は剥離が発生しやすくなるという問題が生じる。このため従来では弾力性を有する接着剤が用いられている。ところが、このような接着剤では長期間使用時に無機質系表面化粧材６が剥離、脱落の危険がある。しかも、従来の全面接着方式では接着剤が乾くまで待つ必要があり、仕上がりまで長時間を要するという問題もある。
【０００６】
本発明は、上記従来の課題に鑑みてなされたもので、その目的とするところは、金属材料と無機質材料との熱膨張率の差によるクラック又は剥離の発生を防止できると共に、長期間の使用時でも脱落の危険をなくすことができ、そのうえ仕上り時間の短縮化を図ることができる複合パネルを提供するにあり、他の目的とするところは、サンドイッチパネルへの無機質系表面化粧材の固着力を高めると同時に無機質系表面化粧材の止水性を高めることができる複合パネルを提供するにある。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明にあっては、一対の金属外皮１，２間に断熱材３が介装されていると共に、長手方向の一端に凸状の嵌合部４が設けられ、他端に嵌合部４が接続可能な凹状の被嵌合部５が設けられたサンドイッチパネル７の外表面に、無機質系表面化粧材６を配置すると共に、無機質系表面化粧材６の複数箇所を固着手段１３によりサンドイッチパネル７に対して固着してなる複合パネルであって、前記無機質系表面化粧材６の複数箇所にはザグリ部３５が予め形成され、前記サンドイッチパネル７の前記ザグリ部３５と対向する位置には、一方の金属外皮１を貫通して前記断熱材３内部に達するルーズホール３６が予め形成されており、前記固着手段１３は、前記無機質系表面化粧材６の前記ザグリ部３６から前記サンドイッチパネル７の前記ルーズホール３６内に挿入される挿着部１１と、この挿着部１１の挿入後に前記ルーズホール３６内部で拡開して前記一方の金属外皮１の裏面に係止されるクリップ部１２とを備えた固着具１３ａにより構成されていることを特徴としており、このように構成することで、無機質系表面化粧材６の固着手段１３間には、サンドイッチパネル７に対して固着されない非固着部９が存在することとなり、金属外皮１と無機質系表面化粧材６との間の熱膨張率の差により応力が生じても、その応力は非固着部９において吸収されることとなり、無機質系表面化粧材６にクラック又は剥離が発生するのを防止できると共に、接着剤を用いずに物理的（機械的）に固着することで長期間使用しても脱落の危険をなくすことができ、さらに従来の全面接着方式と比較して、仕上り時間の短縮化を図ることができる。また、無機質系表面化粧材６のザグリ部３５からサンドイッチパネル７のルーズホール３６に挿着部１１を落とし込み、ルーズホール３６の中でクリップ部１２を拡開させて抜け止めする方式を採用したので、固着具１３ａをサンドイッチパネル７に対して簡単にしかも確実に固着できるようになる。つまり、挿着部１１をサンドイッチパネル７の他方の金属外皮２まで貫通させる必要がなく、挿着部１１の挿入深さを浅くできるので、固着具１３ａによる無機質系表面化粧材６の固着作業が容易となる。
【０００８】
ここで、固着手段１３として、接着材１７を併用するのが好ましく、この場合、サンドイッチパネル７への無機質系表面化粧材６の固着力を高めながら、同時に無機質系表面化粧材６の裏面への水の浸入を防止できるようになる。
【０００９】
また上記無機質系表面化粧材が無塗装であるのが好ましい。
【００１１】
また上記無機質系表面化粧材６の表面に凹設された目地部１０に固着手段１３を挿着してなるのが好ましい。
【００１２】
また上記無機質系表面化粧材６の目地部１０以外の凸状部１４に設けたザグリ部３５に固着手段１３を挿着すると共に、固着手段１３のへッド部１５を充填部材５０にて被覆してなるのが好ましい。
【００１３】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１４】
本実施形態の複合パネルは、図１、図２に示すように、サンドイッチパネル７の外表面には、無塗装の無機質系表面化粧材６が配置されており、その複数箇所が固着手段１３によりサンドイッチパネル７の一方の金属外皮１に固着されている。
【００１５】
上記サンドイッチパネル７は、一対の金属外皮１，２間に断熱材３が介装されている。断熱材３の材質としては発泡性樹脂とかロックウールなどがあるが、特に限定されない。サンドイッチパネル７の長手方向の一端には凸段部２２と嵌合凸部４とが設けられ、他端には凹段部２３と嵌合凹部５とが設けられている。図３は嵌合状態の例を示している。一方のサンドイッチパネル７の凸段部２２が他方のサンドイッチパネル７の凹段部２３の上面に載置された状態で、嵌合凸部４が嵌合凹部５に嵌合している。図３中の２４はビス収納凹所、２５はパッキン、２６は取付ビスである。もちろん、サンドイッチパネル７の端部の接続構造は図３の例には限定されない。
【００１６】
無機質系表面化粧材６は、例えば繊維が充填されたセメント材のようなセメント複合材などの真空成形により成形されており、その表面には複数の凸状部１４とこれを仕切る目地部１０とが形成されている。なお無機質系表面化粧材６の凸状部１４は、タイル調（或いは、石目調、砂岩調、レンガ調等）とされる。なお無機質系表面化粧材６の表面部分はサンドイッチパネル７に固着される段階では無塗装であり、最終的には塗装処理されるものである。また本例では、無機質系表面化粧材６は矩形状に形成され、その一辺のサイズが例えば３００ｍｍ〜９００ｍｍ程度とされ、また、目地部１０における厚みＤ１は例えば５ｍｍ以上、凸状部１４における厚みＤ２は例えば２０ｍｍ以下とされているが、これらの数値に限定されるものではない。
【００１７】
なお、環境保護の観点から、無機質系表面化粧材６の原料としてヘドロなどの廃材（無機質セメント系）を使用し、これを乾燥、素焼きして得られるものを用いることも可能である。
【００１８】
上記無機質系表面化粧材６は、固着手段１３によりサンドイッチパネル７に固着される。本例では固着手段１３として、バルブタイトと称される固着具１３ａが用いられている。無機質系表面化粧材６の複数箇所にはザグリ部３５が予め形成され、サンドイッチパネル７の上記ザグリ部３５と対向する位置には、一方の金属外皮１を貫通して断熱材３内部に達するルーズホール３６が予め形成されている。なお、無機質系表面化粧材６のザグリ部３５は、凸状部１４に設けられる場合、或いは目地部１０に設けられる場合のいずれであってもよく、また図２のように、目地部１０と凸状部１４の両方に設けることも可能であり、適宜変更自在である。
【００１９】
図１、図４、図５に示すように、固着具１３ａは、無機質系表面化粧材６のザグリ部３５からサンドイッチパネル７のルーズホール３６内に挿入される挿着部１１と、断熱材３の内部で拡開して一方の金属外皮１の裏面に対して係止されるクリップ部１２とで構成されている。挿着部１１は、ネジ部１６と、ネジ部１６が貫通する筒形をしたヘッド部１５と、ヘッド部１５に連設されて収縮変形可能なスリーブ１８とで構成されている。ネジ部１６はその先端側の略半分がヘッド部１５を貫通してスリーブ１８内に挿入されていると共に、ネジ部１６の先端１６ａがスリーブ１８の先端部分に固着されている。この固着具１３ａは無機質系表面化粧材６の複数箇所に間隔をあけて配置されており、これにより無機質系表面化粧材６には固着具１３ａにて固着される固着部８と固着されない非固着部９とがそれぞれ存在するようになり、非固着部９によって金属外皮１と無機質系表面化粧材６との間の熱膨張率の差による応力を吸収できる構造となっている。なお、固着具１３ａの構造は図４の例に限定されるものではない。
【００２０】
次に、上記固着具１３ａを用いて無機質系表面化粧材６をサンドイッチパネル７に固着する場合を説明する。先ず、挿着部１１を無機質系表面化粧材６のザグリ部３５からサンドイッチパネル７のルーズホール３６内に落とし込んだ後に、ヘッド部１５を固定用治具（図示せず）にて上から押さえ付けながら、ネジ部１６を上方に引き上げる。これにより、ネジ部１６全体が図４（ａ）の矢印イで示す方向にネジ部１６の先端１６ａがヘッド部１５側に引き寄せられて、スリーブ１８が図４（ｂ）のように収縮変形して蝶形のクリップ部１２が形成され、このクリップ部１２が一方の金属外皮１の裏面に係止されることで、固着具１３ａを介して無機質系表面化粧材６とサンドイッチパネル７の一方の金属外皮１とが互いに固着されるようになる。
【００２１】
このように、無塗装の無機質系表面化粧材６の複数箇所を、固着具１３ｂによりサンドイッチパネル７に固着することによって、無機質系表面化粧材６にはサンドイッチパネル７に対して固着されない非固着部９が複数存在することとなり、これにより金属外皮１と無機質系表面化粧材６との間に熱膨張率の差により応力が生じても、その応力は非固着部９において吸収されることとなり、従って、無機質系表面化粧材６にクラックや剥離が発生するのを未然に防止でき、無機質系表面化粧材６の外観を長期に亘って良好に保つことができるものである。このようにして得られた複合パネルを、内外壁、屋根、床などに使用することによって、軽量で断熱性及び耐火性に優れ且つ工期短縮を図ることができるというサンドイッチパネル特有の効果が得られる。
【００２２】
しかも、無機質系表面化粧材６のザグリ部３５からサンドイッチパネル７のルーズホール３６に挿着部１１を落とし込み、ルーズホール３６の中でクリップ部１２を拡開させて抜け止めする方式を採用したので、固着具１３ａをサンドイッチパネル７に対して簡単にしかも確実に固着できるようになる。つまり、無機質系表面化粧材６を接着剤を用いずに物理的（機械的）に固着することで、長期間使用しても脱落の危険をなくすことができ、施工の信頼性を高めることができるものである。しかも、挿着部１１をサンドイッチパネル７全体に貫通させる必要がないので、挿着部１１の挿入深さが浅くて済むうえに、従来のような全面接着方式と比較して、接着剤が乾くまで待つ必要がなく、仕上り時間の短縮化を図ることができる。
【００２３】
ここで、上記無機質系表面化粧材６のザグリ部３５を、例えば図１に示すように凸状部１４に設けた場合にあっては、へッド部１５を充填部材５０で被覆して覆い隠すようにするのが望ましい。一方、無機質系表面化粧材６のザグリ部３５を、図５に示す目地部１０に設けた場合にあっては、ヘッド部１５を、目地部１０と同色系（例えば黒色）に塗装することによって、外部からヘッド部１５が一層目立たなくすることができる。そして、無機質系表面化粧材６の表面部分を最終的に塗装することで、従来のタイル貼りのものと外観が変わらないものとすることができる。
【００２４】
また、上記固着具１３ａによる固着を行う前に、無機質系表面化粧材６の裏面の外周部に沿って接着材１７となる両面テープ（図２の破線で示す）を貼り、これをサンドイッチパネル７の金属外皮１の表面に接着するようにしている。このように固着具１３ａと、無機質系表面化粧材６の周囲を接着する接着材１７とを併用したことによって、サンドイッチパネル７に対する無機質系表面化粧材６の固着力を高めることができると共に、無機質系表面化粧材６の裏面への水の浸入を防止できるようになり、止水性を同時に高めることができるという利点がある。なお、無機質系表面化粧材６の外周部に配置される接着材１７としては両面テープに限られるものではなく、接着剤による接着であってもよいものである。
【００２５】
さらに、上記ネジ部１６の一部に、予め、ネジ部１６の切り離しを容易とするための切り込み溝を予め形成しておくのが望ましい。これにより、ネジ部１６を最後まで締め上げたときに、不要なネジ部１６を切り込み溝に沿って容易に切り離すことができ、図１又は図５に示すように、ザグリ部３５内に固着具１３ａのへッド部１５を納まり良く収納できるようになる。
【００２６】
なお、図１の例では凸状部１４に配置されるへッド部１５を山形状とし、図５の例では目地部１０に配置されるへッド部１５を皿状としたが、へッド部１５の形状は特に限定されないものである。
【００２７】
【発明の効果】
上述のように請求項１記載の発明にあっては、一対の金属外皮間に断熱材が介装されていると共に、長手方向の一端に凸状の嵌合部が設けられ、他端に嵌合部が接続可能な凹状の被嵌合部が設けられたサンドイッチパネルの外表面に、無機質系表面化粧材を配置すると共に、無機質系表面化粧材の複数箇所を固着手段によりサンドイッチパネルに対して固着してなるので、無機質系表面化粧材とサンドイッチパネルの金属外皮との間には、固着手段により固着されない非固着部が存在することとなり、金属外皮と無機質系表面化粧材との間の熱膨張率の差により応力が生じても、その応力は非固着部において吸収されるようになり、これにより、無機質系表面化粧材にクラック又は剥離が発生するのを防止でき、無機質系表面化粧材の外観を長期に亘って良好に保つことができると共に、物理的（機械的）に固着することによって、長期間使用しても脱落の危険をなくすことができ、施工の信頼性を高めることができる。しかも、従来のような全面接着方式と比較して、接着剤が乾くまで待つ必要がなく、仕上り時間の短縮化を図ることができる。
さらに、前記無機質系表面化粧材の複数箇所にはザグリ部が予め形成され、前記サンドイッチパネルの前記ザグリ部と対向する位置には、一方の金属外皮を貫通して前記断熱材内部に達するルーズホールが予め形成されており、前記固着手段は、前記無機質系表面化粧材の前記ザグリ部から前記サンドイッチパネルの前記ルーズホール内に挿入される挿着部と、この挿着部の挿入後に前記ルーズホール内部で拡開して前記一方の金属外皮の裏面に係止されるクリップ部とを備えた固着具により構成されているので、挿着部をサンドイッチパネルの他方の金属外皮まで貫通させる必要がなく、しかも無機質系表面化粧材のザグリ部からサンドイッチパネルのルーズホールに挿着部を落とし込み、ルーズホールの中でクリップ部を拡開させて抜け止めする方式を採用したので、固着具をサンドイッチパネルに対して簡単にしかも確実に固着できるようになる。つまり、挿着部の挿入深さを浅くできるので、固着具による無機質系表面化粧材とサンドイッチパネルとの固着作業が容易となる。そのうえ断熱材内部でクリップ部を拡開させるので、挿着部の挿入時の外径寸法は小さくて済み、従って、サンドイッチパネルに設けられる挿入孔の形成が容易となる。
【００２８】
また請求項２記載の発明は、請求項１記載の効果に加えて、固着手段として、接着材を併用したので、サンドイッチパネルに対する無機質系表面化粧材の固着力を高めながら、無機質系表面化粧材の裏面への水の浸入を防いで、止水性を同時に高めることができる。
【００２９】
また請求項３記載の発明は、請求項１記載の効果に加えて、無機質系表面化粧材が無塗装であるので、サンドイッチパネルとの固着後に無機質系表面化粧材の表面に塗装を施すことで、ユーザーの要望に応じた任意の色模様（例えばタイル調、石目調など）を形成できるものである。
【００３１】
また請求項４記載の発明は、請求項１記載の効果に加えて、無機質系表面化粧材の表面に凹設された目地部に固着手段を挿着してなるので、固着手段が外部から目立たなくなり、固着手段による無機質系表面化粧材の外観低下を防止できる。
【００３２】
また請求項５記載の発明は、請求項１記載の効果に加えて、無機質系表面化粧材の目地部以外の凸状部に設けたザグリ部に固着手段を挿着すると共に、固着手段のへッド部を充填部材にて被覆してなるので、充填部材によってへッド部が外部から目立たなくなり、固着手段による無機質系表面化粧材の外観低下を防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a composite panel mainly used for inner and outer walls, roofs, floors, and the like, and more particularly to a technique for joining a sandwich panel and an inorganic surface decorative material.
[0002]
[Prior art]
Conventionally, ALC panels that are lightweight and have excellent heat insulation and fire resistance have been used for inner and outer walls, roofs, floors, etc., and in order to improve the appearance design of this ALC panel, tiles are pasted on the surface. However, such a tile finish has a problem with its durability.
[0003]
Therefore, in order to improve the durability, as shown in FIG. 6, the entire surface of the ALC panel 20 is bonded to the surface of the ALC panel 20 using the adhesive 21 or double-sided tape. Composite panels are known.
[0004]
In recent years, instead of ALC panels, sandwich panels with a heat insulating material interposed between a pair of metal skins are being used for inner and outer walls, roofs, floors, etc. Many composite panels having a plate-like inorganic surface decorative material 6 bonded thereto are being adopted.
[0005]
[Problems to be solved by the invention]
However, in the case of a composite panel in which the inorganic surface decorative material 6 and the sandwich panel are combined, the conventional whole surface adhesion method is used as a method of bonding the inorganic surface decorative material 6 to one metal skin of the sandwich panel. When it is used, there is a difference in thermal expansion coefficient between the metal material and the inorganic material, so stress due to the difference in thermal expansion coefficient is applied to the inorganic surface decorative material 6, and the inorganic surface decorative material 6 is cracked or peeled off. The problem that it becomes easy to occur occurs. For this reason, an adhesive having elasticity has been conventionally used. However, with such an adhesive, there is a risk that the inorganic surface decorative material 6 may be peeled off or dropped off during long-term use. In addition, in the conventional full surface adhesion method, it is necessary to wait until the adhesive dries, and there is a problem that it takes a long time to finish.
[0006]
The present invention has been made in view of the above-described conventional problems. The object of the present invention is to prevent the occurrence of cracks or peeling due to the difference in thermal expansion coefficient between a metal material and an inorganic material, and to use for a long time. In order to provide a composite panel that can eliminate the risk of falling off, and to shorten the finishing time, the other purpose is to fix the inorganic surface cosmetics to the sandwich panel. It is in providing the composite panel which can raise the water-stop property of an inorganic type surface cosmetic material simultaneously.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, the heat insulating material 3 is interposed between the pair of metal shells 1 and 2, and a convex fitting portion 4 is provided at one end in the longitudinal direction. The inorganic surface decorative material 6 is disposed on the outer surface of the sandwich panel 7 provided with the recessed mated portion 5 to which the fitting portion 4 can be connected at the other end, and a plurality of locations of the inorganic surface decorative material 6 are provided. Is fixed to the sandwich panel 7 by the fixing means 13, and a counterbore part 35 is previously formed at a plurality of locations of the inorganic surface decorative material 6, and the counterbore part 35 of the sandwich panel 7 is formed.
