本発明は石綿セメント製品を使用した軽量複合パネル並
びにその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lightweight composite panels using asbestos-cement products and methods of manufacturing the same.
近年、オートクレーブ養生気泡コンクリートＡｕｔｏ
ｃｌ’ａｖｅｄ Ｌｉ’ｈｔ−ｗｅｉ ’ｈｔ Ｃｏｎ
ｃｒｅｔｅ、（以下ＡＬＣと称す）はその比重が０．５

なる故、熱伝導率が低いため断熱性富む。In recent years, autoclave cured aerated concrete Auto
cl'aved Li'ht-wei'ht Con
crete (hereinafter referred to as ALC) has a specific gravity of 0.5
Therefore, it is lightweight, and since its cells are almost closed cells, its thermal conductivity is low, making it highly insulating.
又主原料が石灰質原料（生石灰あるいはセメント等）や
珪酸質原料（硅石等）であるため耐火性も良く、現場で
の施工も容易である等の多くの長所を有する故、ＡＬＣ
の使用は毎年大巾の増加を示してきた。In addition, since the main raw materials are calcareous materials (quicklime or cement, etc.) and silicic materials (silica stone, etc.), ALC has many advantages such as good fire resistance and easy construction on site.
The use of large cloth has shown an increase every year.
ところで、上述の如く多くの長所を有するＡＬＣも、基
本的には発泡体である故、比重との対比の割合において
は、強度が大であっても、末だ強度的に不允分であるか
ら、多少とも強度を必要とする箇所には鉄筋又はメタル
ラスを入れて施工してきた。By the way, ALC, which has many advantages as mentioned above, is basically a foam, so even if its strength is high in comparison to its specific gravity, it is still inadequate in terms of strength. Since then, reinforcing bars or metal lath have been installed in places where more or less strength is required.
然し乍らＡＬＯはセメントコンクリートに比較して、ア
ルカリ性が多少低く、且つ多孔体である故、鉄筋が錆び
易い。However, since ALO has a somewhat lower alkalinity than cement concrete and is porous, reinforcing bars are susceptible to rust.
それで鉄筋に防錆処理を施さねばならなかった。Therefore, the reinforcing steel had to be treated to prevent rust.
さらに鉄筋を補強に使用するとＡＬＯめ発泡性製造方法
の本質上、どうしても鉄筋等の挿入材の上部に巣の発生
が避けられず、従って挿入材との完全固着は不可能であ
る。Furthermore, if reinforcing bars are used for reinforcement, due to the nature of the ALO foam manufacturing method, it is inevitable that cavities will occur above the inserts such as reinforcing bars, and therefore complete adhesion to the inserts is impossible.
尚、鉄筋等の金属性補強挿入材を使用した場合、現場施
工中に切断加工の必要が生じたとき、切断加工が非常に
困難である。In addition, when a metallic reinforcing insertion material such as a reinforcing bar is used, it is very difficult to perform cutting when it becomes necessary to perform cutting during on-site construction.
又、鉄筋の配筋自体が切断を考慮したものでないから、
敢て切断した場合、パネル自体の曲げ強度が設計以下と
なるさらに、複合パネルの製造には、有機質もしくは無
機質の接着剤が用いられているが、いずれの場合も広い
接着表面を均一に表面処理することはきわめて厄介であ
るうえ、有機質接着剤の場合には耐火性に問題があり、
また無機質接着剤の場合には、施工方法によっては剥離
の問題を生じる。Also, since the reinforcing bar arrangement itself is not designed with cutting in mind,
If the panel is intentionally cut, the bending strength of the panel itself will be lower than the design.Furthermore, organic or inorganic adhesives are used to manufacture composite panels, but in either case, the large adhesive surface must be uniformly treated. It is extremely troublesome to do so, and organic adhesives have problems with fire resistance.
Furthermore, in the case of inorganic adhesives, peeling problems may occur depending on the method of application.
また耐火性、接着力の優れた安価な接着剤はいまだに開
発されていないのが現状である。Furthermore, at present, an inexpensive adhesive with excellent fire resistance and adhesive strength has not yet been developed.
本発明は、ＡＬＣの上述の如き欠点を除き、比較的強度
を必要とするところへ、その長所を一層発揮せしめる利
点の大なるＡＬＣの複合パネル及びその製造方法である
。The present invention is an ALC composite panel and a method for manufacturing the same, which have the great advantage of eliminating the above-mentioned drawbacks of ALC and further demonstrating its advantages in areas that require relatively high strength.

欠点を一挙に解決した利点の多いものである。As described above, the present invention is a lightweight composite panel using an asbestos-cement product characterized by a structure in which an asbestos-cement plate is used as a core material or a surface material, and the plate-like body is formed with ALC. After placing the asbestos slate in place in advance, the raw material slurry for lightweight composite panels is injected,
A lightweight composite panel made of ALC characterized in that it is pre-cured and then autoclaved to cause a hydrothermal reaction between the base material and the components in the asbestos slate at the interface, resulting in a strong integration. By using cement slate plates instead of conventional metal reinforcing materials such as reinforcing bars and metal rice, there is no need for anti-rust treatment as with conventional reinforcing materials, and cutting is easy. There is no difficulty in processing, and the asbestos-cement plate and ALC are strongly integrated, which prevents insufficient strength and deterioration of sound insulation due to poor adhesion with reinforcing materials. It has many advantages and solves all the disadvantages all at once.
