本発明は、建築用複合断熱板材の改良に関し、建築材料
を製造、販売、使用する産業分野で利用されるものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to the improvement of composite insulation board materials for buildings, and is utilized in the industrial field of manufacturing, selling, and using building materials.
近時、建築物の軽量化、工期の短縮化、省エネルギー等
の目的から、所謂Ａ、Ｌ、Ｃ，板材（軽量気泡コンクリ
ート板材）が大量に使用されていることは周知であり、
また、Ａ、Ｌ、Ｃ，板材は極めて軽量であり、優れた断
熱性及び切断、打釘の容易性等々の数多くの長所を備え
ているために最近益々その需要が増大しつつあることも
周知である。It is well known that in recent years, so-called A, L, C, plates (lightweight aerated concrete plates) are being used in large quantities for the purpose of reducing the weight of buildings, shortening construction periods, and saving energy.
It is also well known that the demand for A, L, C, and board materials has been increasing recently because they are extremely lightweight and have many advantages such as excellent insulation properties and ease of cutting and nailing. It is.
然るに、Ａ、Ｌ、Ｃ，板材には多数の気泡が内在されて
いるため、その強度は必ずしも充分満足するべきもので

め、極めて湿潤、透水し易（、したがって乾燥時には抜
群の良断熱性を示すが、湿潤時には断熱性、強度性が大
巾に低下するという重大な欠点がある。However, since the A, L, C, and board materials contain a large number of air bubbles, their strength is not necessarily satisfactory, and they also lack water resistance and impermeability, so they cannot be used in extremely wet or wet conditions. It is easily permeable to water (therefore, it exhibits excellent heat insulation properties when dry, but has a serious drawback in that its heat insulation properties and strength deteriorate significantly when wet.
そこで、Ａ、Ｌ、Ｃ，板材の強度を向上するために、鉄
筋、金網等の補強材を内装した製品が開発提供されてい

ばかりでなく、例えば隅角部等の補強材不在個所の脆弱
欠点は全く改善され得ぬと共に、補強材の内装は資材及
び工程の増加を来すために不経済である。Therefore, in order to improve the strength of A, L, C, and plate materials, products have been developed and provided that have internal reinforcing materials such as reinforcing bars and wire mesh, but these reinforcing materials become an obstacle when cutting and nailing. Not only that, but the fragility defects at corners where no reinforcing material is present cannot be improved at all, and adding reinforcing material to the interior is uneconomical because it increases the number of materials and processes.
また、耐水性の向上及び湿潤の防止を図って、防水塗料

できる程度に保ち得るものは提供されていない。In addition, methods have been used to improve water resistance and prevent moisture, such as applying waterproof paint or coating with a waterproof film, but it is still not possible to maintain sufficient heat resistance when wet. Nothing is provided.
本発明は、上記背景技術に鑑みて発明されたもので、す
なわち、従来のＡ、Ｌ、Ｃ，板材に較べて、曲げ強度、

有用な建築用複合断熱板材を提供することを目的とする
。The present invention was invented in view of the above-mentioned background technology, and has a higher bending strength than conventional A, L, C, and plate materials.
The object of the present invention is to provide an extremely useful composite insulation board material for construction that has excellent compressive strength, water resistance, heat insulation properties, workability, etc.
上記の目的を達成するために、本発明に係る建築用複合

00 parts by weight of asphalt aqueous emulsion 1.
5 to 10 parts by weight is added thereto, and an uncured lightweight mortar mixture prepared by adding the required amount of water, aggregate, and 0.001 to 5 parts by weight of a protein-based air entraining agent, etc. is poured and hardened,
The lightweight mortar mixture layer is integrally formed on a construction board.

値が得られず、また、１０重量部を超えた場合は、性能
のより以上の ′向上を望み得られないと共にコスト高
をもたらすことが判明したからである。In the present invention, the component range of the lightweight mortar mixture is specified to the above ratio for the following reasons:
If the amount of asphalt aqueous emulsion added is less than 1.5 parts by weight relative to 0M parts, the strength of the foam in the product board will be low and the water absorption will be high, making it impossible to obtain satisfactory performance values. Furthermore, it has been found that if the amount exceeds 10 parts by weight, further improvement in performance cannot be expected and costs are increased.
また、セメント １００重量部に対して蛋白質系空気連

板材の比重が高くなって断熱性が低下し、所期の性能を
期待できず、また、５重量部を超えると、比重は低くな
って断熱性は向上するが、板材としての強度が低下し、
現在の研究段階で強度的に問題のあることが判明したか
らである。In addition, if the amount of protein air entraining agent added to 100 parts by weight of cement is less than 0.001 parts by weight, the specific gravity of the product board will increase and the insulation properties will decrease, making it impossible to expect the desired performance. Moreover, if it exceeds 5 parts by weight, the specific gravity will decrease and the heat insulation properties will improve, but the strength as a plate material will decrease.
This is because the current research stage has revealed that there is a problem with its strength.

4 parts by weight of water-repellent asphalt emulsion, 70 parts by weight of fly ash, 50 parts by weight of silica sand No. 7, 0.05 parts by weight of protein-based air entrainment agent, 0 parts by weight of alkali-resistant glass fiber.
．． 01 parts by weight and 60 parts by weight of water were added and thoroughly kneaded, and the uncured lightweight mortar mixture was poured in and cured to obtain a composite insulation board material for construction in which the lightweight mortar mixture was integrally layered on plywood.

縮化を図り得るものである。In the present invention, in order to improve the adhesive strength between the upper lightweight mortar layer and the base construction board material, the lightweight mortar mixture may be poured after applying an adhesive to the surface of the base construction board material. Furthermore, if another fire-resistant construction board material such as gypsum board or tile is laminated on the surface of the lightweight mortar mixture layer layered on the base construction board material in the above example, the heat insulation and fire resistance can be further improved. At the same time, the appearance is good, and the construction period can be shortened by saving labor in the process.

It has the great advantage of easily combining the above-mentioned properties, and since all the bubbles generated by the protein-based air communication agent are closed cells, the above-mentioned heat insulation properties and water resistance are further improved. .
