【発明の詳細な説明】 〔技術分野〕 本発明は、建築物の屋根下地となる平面部に断熱性を
付与するための断熱施工法の改良に関し、断熱材を製
造、販売、使用する産業分野で利用されるものである。Description: TECHNICAL FIELD The present invention relates to an improvement in a heat insulating construction method for imparting heat insulating properties to a flat surface portion serving as a roof base of a building, and an industrial field of manufacturing, selling and using a heat insulating material. Is used in.
例えば、建築物の屋根（所謂屋根仕上材）には、瓦、
波板（石綿スレート、金属及び塩化ビニール波板等）、
金属平板、モルタル、タイル等の極めて多種多様のもの
が使用されているが、これらの屋根仕上材を施工する場

居ぶき、しっくい、木毛セメント板、アスファルトルー
フィング、シンダーコンクリート、防水モルタル等々の
多種多様の材料が使用されている。For example, roofs of buildings (so-called roof finishing materials) include roof tiles,
Corrugated sheet (asbestos slate, metal and vinyl chloride corrugated sheet, etc.),
A wide variety of materials such as metal flat plates, mortar, tiles, etc. are used, but when these roof finishing materials are constructed, the base material (cedar, cypress, etc.), clay, Doi duster, A wide variety of materials are used, such as plaster, wood wool cement board, asphalt roofing, cinder concrete, waterproof mortar and so on.
ところで、これらの下地材は、上層の屋根仕上材が万

保有することが必要であり、さらに望ましくは軽量にし
て不燃性であることが要求されるのであるが、前述した
各下地材は、これらの必要条件の全てを同時に満たして
いない。By the way, these base materials are required to be waterproof so that water will not leak indoors even if the roof finishing material in the upper layer should be damaged. In addition, in consideration of comfortable habitability, these base materials have sufficient heat insulating properties. However, it is desirable that the base materials described above be lightweight and nonflammable, but the above-mentioned base materials do not meet all of these requirements at the same time.
例えば、屋根仕上材に瓦を用いて屋根葺を行う場合に

断熱性が皆無であるため、このような屋根の家は漏水の
恐れと共に外気の寒暖の影響を大きく受け易く、居住性
が極めて悪いという諸問題がある。For example, when explaining roofing using roof tiles as roof finishing material, first, after roofing a base plate such as cedar, cypress, etc. as a base material, set an appropriate interval so that the tiles placed on it will not slip off. While maintaining the stake and then laying a waterproof layer such as asphalt waterproof paper and placing the roof tile on it, the roof layer is not adhered at all because the waterproof layer and the roof tile are not adhered. Often blown off, and because the asphalt waterproof paper is weak, it is not only easy to break,
Since there is no heat insulation, a house with such a roof is susceptible to water leakage as well as being affected by the cold and warm air of the outside air, and there is a problem that the habitability is extremely poor.
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、極めて優秀な断熱性と防水性を保有し、且つ
軽量であると共に不燃性であるという特長を備えた断熱
部を建築物または保冷車などの屋根下地に断熱部を施工
形成し得ると共に、この断熱部の接着性を良好に保たせ
得る等の特長を備えた理想的な要断熱個所への断熱施工
法を提供することを目的とする。The present invention has been invented in view of the above background art,
That is, while having extremely excellent heat insulation and waterproofness, and while being able to construct and form a heat insulation part having a feature of being lightweight and non-combustible, a heat insulation part can be formed on a roof substrate of a building or a cold storage car, It is an object of the present invention to provide a heat insulating construction method for an ideal heat insulating point having features such as good adhesion of the heat insulating portion.
上記の目的を達成するために、本発明に係る断熱施工
法は、セメント100重量部に対して、フライアッシュ、
炭酸カルシウムその他の粉末骨材30〜200重量部、繊維
物質0.1〜30重量部、アスファルト水性エマルジョン100
重量部にアクリル系樹脂（水性エマルジョン及び／又は
粉末樹脂）３〜60重量部を添加したもの1.5〜10重量
部、蛋白質系空気連行剤0.001〜５重量部を加え、さら
に適量の水を加えて攪拌混練し、適切な比重の断熱部と
なる混合物を作成し、この混合部を屋根下地となる平面
部に層成し、常温において放置固化させることを特徴と
するものである。In order to achieve the above object, the heat insulating construction method according to the present invention, with respect to 100 parts by weight of cement, fly ash,
30 to 200 parts by weight of calcium carbonate and other powder aggregates, 0.1 to 30 parts by weight of fibrous substances, asphalt aqueous emulsion 100
1.5 to 10 parts by weight of acrylic resin (aqueous emulsion and / or powder resin) added to 3 to 60 parts by weight, 0.001 to 5 parts by weight of protein air entraining agent, and an appropriate amount of water. It is characterized in that the mixture is agitated and kneaded to prepare a mixture which becomes an adiabatic portion having an appropriate specific gravity, and the mixture portion is layered on a flat surface portion which becomes a roof substrate and allowed to stand and solidify at room temperature.
本発明において、セメント100重量部に対する添加成
分量範囲を上記の割合に規定したのは次の理由に基づ
く。In the present invention, the range of the amount of the additive component with respect to 100 parts by weight of cement is defined to be the above ratio for the following reason.
セメント100重量部に対して、フライアッシュその他
の粉末骨材の添加量が30重量部未満の場合、及び200重
量部を超えた場合は、いずれの場合でも長期的な機械的
強度が低下して性能的に満足な数値を得られない。With respect to 100 parts by weight of cement, if the amount of fly ash or other powder aggregate added is less than 30 parts by weight, or if it exceeds 200 parts by weight, the long-term mechanical strength decreases in any case. It is not possible to obtain satisfactory performance values.
また、アスファルト水性エマルジョン100重量部にア
クリル系樹脂の添加量が３重量部未満の場合は、耐候性
及び強度的に満足な数値が得られず、また、60重量部を
超えるとコスト高になって採算がとれない。更に、この
アスファルト水性エマルジョンとアクリル系樹脂の配合
物の添加量がセメント100重量部に対して1.5重量部未満
の場合は、耐水性、耐候性及び機械的強度が不充分とな
り、また、10重量部を超えるとコスト高になると共に強
度的にもマイナスになる。If the amount of acrylic resin added to 100 parts by weight of the asphalt aqueous emulsion is less than 3 parts by weight, weather resistance and strength will not be satisfactory, and if it exceeds 60 parts by weight, the cost will increase. Profitable. Furthermore, if the amount of the asphalt aqueous emulsion and acrylic resin compounded is less than 1.5 parts by weight relative to 100 parts by weight of cement, the water resistance, weather resistance and mechanical strength will be insufficient, and 10 parts by weight. If it exceeds the number of parts, the cost will be high and the strength will be negative.
また、セメント100重量部に対して、蛋白質系空気連
行剤の添加量が、0.001重量部未満の場合は、比重が高
くなると共に断熱性の低下を来し、また、５重量部を超
えると比重は低くなり、断熱性は向上するが、強度が低
下する。If the amount of protein-based air entraining agent added is less than 0.001 part by weight relative to 100 parts by weight of cement, the specific gravity increases and the heat insulating property decreases, and if it exceeds 5 parts by weight, the specific gravity increases. Is low and the heat insulation is improved, but the strength is reduced.

4 parts by weight of 0 parts by weight, 1 part by weight of glass fiber, 100 parts by weight of asphalt aqueous emulsion and 3 parts by weight of acrylic powder resin, 0.5 parts by weight of protein-based air entraining agent, and 40 parts by weight of water. Add and knead to make a paste-like compound that becomes an insulating part with an appropriate specific gravity, and apply this compound to the base plate and heat insulating material to a thickness of 50 mm on the base plate, and in the uncured state, The roof was placed by placing tiles on it. With this paste-like composition, the heat insulating property and waterproof property of the roof portion were remarkably improved, and the roof plate and the roof tile were sufficiently bonded to each other to prevent the roof tile from sliding off.

果を次表に示す。なお、比重を除く試験項目の測定結果
は比重が0.6の材料について示している。The following table shows the results of performance comparison between the heat insulating part formed according to the heat insulating construction method of the above example and the commercially available ALC and the commercially available hard urethane. The measurement results of the test items excluding specific gravity are shown for the material with specific gravity of 0.6.

り、断熱性及び耐水性に関してもA.L.C.より著しく優
れ、有機材料であるウレタンフォームと充分比較し得る
特性を備えている。 As is clear from the above table, in the case of the present invention, regarding mechanical strength (compressive strength, bending strength), urethane foam, which is weak like paper, is not a problem, and excellent strength as a heat insulating material is recognized. It is significantly superior to ALC, which is significantly superior to ALC in terms of heat insulation and water resistance, and has properties sufficiently comparable to urethane foam, which is an organic material.

配合物をビル屋上の防水層及び押えコンクリート（シリ

層成した。(Example 2) 100 parts by weight of Portland cement and 8 parts of calcium carbonate
0 parts by weight, 1 part by weight of glass fiber, 100 parts by weight of asphalt aqueous emulsion and 20 parts by weight of acrylic aqueous emulsion added 8 parts by weight, protein-based air entraining agent 0.1
Add 40 parts by weight of water to each part, and knead to make a paste-like compound that becomes an insulating part with an appropriate specific gravity, and use this compound as a waterproof layer for the roof of the building and a holding concrete (cylinder concrete) layer It was used as a material, and a coating layer was formed to the required thickness.
このペースト状配合物によりビルの屋上部分の断熱性
は著しく向上され、防水性も良好であると共に屋上部分
の軽量化を図り得て、建造物の重量負担を著しく軽減し
得た。This paste-like composition markedly improved the heat insulating property of the rooftop of the building, had good waterproofness, and was able to reduce the weight of the rooftop, thereby significantly reducing the weight burden of the building.
上述の如く、本発明の断熱施工法においては、断熱材
として使用する混合物の独自の配合成分と配合割合によ
り、建築物などの平面部に、従来のA.L.C.と較べて断熱
性、耐水性が格段に優れ、且つ曲げ強度、圧縮強度でも
著しく優れた断熱部を形成し得ると共に、現場において
も容易に施工できるので能率の向上による工期の短縮化
を図り得るものである。As described above, in the heat insulation construction method of the present invention, the heat insulation and water resistance are significantly higher than those of conventional ALC on a flat part such as a building due to the unique mixture components and mixture ratio of the mixture used as the heat insulating material. In addition to being able to form a heat insulating portion which is excellent in bending strength and compressive strength, and can be easily installed on site, it is possible to shorten the construction period by improving efficiency.
また、本発明により施工形成された断熱部は著しく軽
量であるため、これを建築物の屋根、屋上及び保冷車等
の要断熱個所に適用した場合は、建築物及び保冷車等に
対する重量負担を著しく軽減できる利点がある。Further, since the heat insulating portion constructed and formed according to the present invention is remarkably lightweight, when it is applied to a heat insulating point such as a roof of a building, a rooftop, or a cold storage vehicle, a weight burden is imposed on the building and the cold storage vehicle. There is an advantage that it can be significantly reduced.
更に、本発明では、断熱部に気泡を含有せしめる手段
として蛋白質系空気連行剤を使用しているので、その添
加量や攪拌時間、攪拌速度を変化調節することにより、
発生する気泡の径を大小自由に変え得て上記の諸特性を
容易に調節し得る多大な利点があると共に、蛋白質系空
気連通剤によって生じる気泡は全て独立気泡であるた
め、発泡ウレタン等と同様に上記の断熱性及び耐水性は
一層向上されるものである。Further, in the present invention, since the protein-based air entraining agent is used as a means for containing bubbles in the heat insulating section, by adjusting the addition amount and stirring time and the stirring speed,
There is a great advantage that the diameter of the generated bubbles can be changed to any size, and the above various properties can be adjusted easily.Because all the bubbles generated by the protein-based air communicating agent are closed cells, it is similar to urethane foam. In addition, the above heat insulation and water resistance are further improved.
