［従来の技術、発明が解決しようとする問題点］ 最近、内装・外装建材として、厚さ11〜20mmの天然石厚
板や人工結晶化ガラス板が多用されている。[Prior Art, Problems to be Solved by the Invention] Recently, natural stone planks and artificial crystallized glass plates having a thickness of 11 to 20 mm are widely used as interior / exterior building materials.
しかしながらこの種の建材は重量が極めて重く施工が
困難のため大型板を使用することができない特殊な取
付治具，工法を必要とする高価であるなどの問題があ
る。However, this type of building material has a problem that it is expensive and requires a special mounting jig that cannot use a large plate and a construction method because it is extremely heavy and difficult to construct.
これらの問題点を解決する方法として、アルミニウムの
ハニカム材を下地材として、厚さ１〜10mmの天然石の薄
板を接着したアルミハニカム大理石が提案されている。As a method of solving these problems, an aluminum honeycomb marble is proposed in which a thin plate of natural stone having a thickness of 1 to 10 mm is bonded to an aluminum honeycomb material as a base material.
このアルミハニカム大理石は、上記問題点の，の改
善を図っているものの、アルミニウムを使用しているた
め、耐火性（防火性）の面で劣り、天然石が極めて薄く
下地材が透けて見えるために天然石等の持つ透明感のあ
る美しさが失なわれる。更にアルミニウム部分が切断し
難く、現場での施工が困難などの欠点を有している。Although this aluminum honeycomb marble aims to improve the above-mentioned problems, because it uses aluminum, it is inferior in terms of fire resistance (fire resistance), and natural stone is extremely thin and the underlying material can be seen through. The transparent beauty of natural stones is lost. Further, it has a drawback that the aluminum part is difficult to cut and construction on site is difficult.
本発明はこのような欠点を除去した白色度の高い、高強
度軽量ケイ酸カルシウム板を下地材に用いた複合軽量石
材であり、耐熱性，加工性，防火性，寸法安定性，耐候
性にも優れた建材を提供することを目的としている。The present invention is a composite lightweight stone material that uses a high-strength lightweight calcium silicate plate having a high whiteness and eliminating such defects as a base material, and has excellent heat resistance, workability, fire resistance, dimensional stability, and weather resistance. Also aims to provide excellent building materials.

となっているため、接着剤層が着色するのは好ましくな
く、透明性に優れた接着剤を使用した方が天然石の特性
を引き出すことが可能である。Reference numeral 2 denotes an adhesive layer, which adheres the thin plate and the lightweight calcium silicate plate. As the adhesive, a normal adhesive can be used, but as described above, the whiteness of the lightweight calcium silicate plate is an important factor for producing the transparent beauty of the thin plate. It is not preferable that the adhesive layer is colored, and it is possible to bring out the characteristics of natural stone by using an adhesive having excellent transparency.
３はシーラー剤層である。軽量ケイ酸カルシウム板と薄
板との接着を行うために、軽量ケイ酸カルシウム板に浸
透型または皮膜型のシーラー剤を20〜200g/m2程度塗布
する。3 is a sealer agent layer. In order to bond the lightweight calcium silicate plate and the thin plate, a light-weight calcium silicate plate is coated with a penetrating or film-type sealer agent at about 20 to 200 g / m 2 .

に記載の方法で好適に製造可能である。4 is a lightweight calcium silicate plate, for example, a bulk density of 0.4 to 0.6 g / cm
3 , bending strength 80-130kgf / cm 2 , bending specific strength 220kgf / cm 2 or more, whiteness 80-97, thermal conductivity 0.09kcal / m ・ h ・ ° C or less,
A non-combustible material that has a length change rate of 0.06% or less when absorbing water, a nail pull-out resistance value of 30 kg / piece or more, and a wood screw holding force of 30 kg / piece or more, and is a material with improved fire resistance, rigidity, processability, and heat insulation. Function as. The light-weight calcium silicate plate can be cut with a normal saw and nailed as in the case of wood. For example, Japanese Patent Application No. 60-261311 (JP-A-62-123053).
It can be preferably produced by the method described in 1.

ィクルボード」に準拠して測定した値である。Here, whiteness is JIS Z8730 "color difference display method", length change rate when absorbing water is JIS A5418 "asbestos cement calcium silicate board", nail pullout resistance value is JIS Z2121 "wooden nail pullout resistance test method", The wood screw holding force is a value measured according to JIS A5908 "Particle board".
５はシーリング材である。複合軽量石材の壁面への取付
は施工方法によって異なるが、乾式工法で特に雄，雌型
の連結部を有する部材として使用する場合には、雄部に
水の侵入を防止するシーリング材を取り付ける。5 is a sealing material. The attachment of the composite lightweight stone to the wall surface differs depending on the construction method, but when using it as a member having a male-female connecting portion in the dry method, attach a sealing material to prevent water from entering the male portion.
６は撥水剤層である。当該複合軽量石材を内装材として
使用する場合には、軽量ケイ酸カルシウム板の裏面に特

ことが多い。6 is a water repellent layer. When the composite lightweight stone material is used as an interior material, it is not necessary to apply a special water repellent treatment to the back surface of the lightweight calcium silicate plate. However, when it is used as an exterior material, a commercially available water repellent is often applied in order to prevent peeling of the thin plate due to water intrusion from the back surface.
７はクリヤー樹脂層である。大理石などの比較的耐候性
の低い材料では、数年も経つと表面の光沢が失なわれる
ケースが多いので、必要に応じて表面に樹脂処理を行う

ップ化を図るには、EBやUV硬化処理によるクリヤー樹脂
塗布が好ましい。樹脂層の厚さは厚い程良いが、薄板の
特性保持及びコストとの関係から10〜100μｍ程度が適
当である。7 is a clear resin layer. Since a material having relatively low weather resistance, such as marble, often loses its gloss over a period of several years, it is preferable to treat the surface with a resin if necessary. In this case, clear resin is preferable for maintaining the properties of the thin plate, and clear resin coating by EB or UV curing treatment is preferable in order to improve weather resistance, hardness and speed of the process. The thicker the resin layer is, the better. However, from the viewpoint of maintaining the characteristics of the thin plate and the cost, about 10 to 100 μm is suitable.
尚、御影石や結晶化ガラスの薄板は、耐候性が比較的良
いので必ずしもこの処理を施さなくても良い。Incidentally, a thin plate of granite or crystallized glass does not necessarily need to be subjected to this treatment since it has relatively good weather resistance.
