【産業上の利用分野】
本発明は、外断熱壁材、又は床材（屋外床、室内床）等の建築下地材の製造方法と、この方法で製造される外断熱壁材、又は床材等の建築下地材、並びに外壁の構築工法、又は屋外床面の構築工法に関する。
【０００２】
【従来の技術】
従来、この種の外断熱壁材としては、特開平７−３３１７６１号の断熱成形板及びその施工法がある（文献（１）とする）。その内容は、断熱材と粗布と表面材とを積層一体化した板状成形物で、断熱材の側端面より粗布がはみ出している断熱成形板と、この断熱成形板を施工する際に、板状成形物を、下地面に接着剤により貼付けるとともに、その目地部に、はみ出し粗布部分を配置して接着剤により貼付け、このはみ出し粗布部分に、必要に応じて化粧仕上材を塗布する施工法である。この発明は、施工が容易で、施工後の接合目地部の強度が優れていることを特徴とする。また実用新案登録第３０１３３０５号の施工用発泡樹脂ボードがある（文献（２）とする）。この考案は、発泡樹脂からなる施工用ボードと、ラスとで構成し、このラスが発泡樹脂の表面に一体的に融着された構造である。この考案は、ラスの耐剥離効果が確保できること、また施工用ボード自体の強度の向上が図れること、又は発泡樹脂の断熱・防水等の特性により、別途断熱材、防水シート等の付設をなくし得ることで、作業効率の向上等が図れること等の特徴がある。
また従来施工されている、断熱外壁工法は、通常、外壁面に防水シートを張装し、発泡ボードを接着又はビス止め等を介して取付け、その後、メッシュを同様な方法で貼付ける。そして、施工壁地（発泡ボードとメッシュの表面）及び目地部にモルタルを塗布した後に、目地部にメッシュを同様にして取付ける。そして、余分のモルタルを除去して、略１日程度養生する。この養生後に上塗り材を塗布する工法である。
【０００３】
【発明が解決しようとする課題】
前記文献（１）は、断熱材と粗布と表面材とを積層一体化した板状成形物で、断熱材の側端面より粗布がはみ出している構成である。しかし、このはみ出している粗布は、板状成形物を製造する際に邪魔となり、成形に難渋すること、また施工に際しては、板状成形物からの粗布の剥離に技術と、手間を要すること、等の課題が考えられる。そして、このはみ出し粗布が四周辺方向では、前述の課題はことのほか大変である。また文献（２）は、発泡樹脂とラス及びモルタル外壁材との組合せの施工用発泡樹脂ボードである。しかし、この考案は、モルタル層を有する構造である。従って、本発明が意図する軽量で、施工の容易な建築下地材とは、内容的に異なる。また本発明が意図する特徴は達成できない問題点がある。
【０００４】
尚、前述した従来の断熱外壁工法は、何れも左官職人等の職人による施工であり、左官職人の手当ての困難性、コストの上昇、施工期間の拡大、又は手間を要すること、等の課題を抱えている。そして問題となるのが、目地部のラスの取付け（張装）、モルタルの塗布等である。この作業が大変であること、熟練を要すること、等の課題があり、早急な解決が望まれているとともに、市場性の拡充に障害となっていることが判明した。

【発明の実施の形態】
以下、本発明の実施例を説明する。
【００２０】
図１は建築下地材の要部を示した一部欠截の斜視図、図２は建築下地材の側面図、図３（イ）〜（ト）は建築下地材を製造する過程を示す模式図、図４は建築下地材を折り曲げた状態の側面図、図５は施工状態を説明する俯瞰模式図、図６は建物の玄関への利用の一例を示す縮尺模式図、また図７はルーフバルコニーへの利用の一例を示す縮尺模式図、図８はベランダへの利用の一例を示す縮尺模式図、をそれぞれ示す。さらに図９は外断熱構造の建物とした場合の使用例における結露の発生を示す図表、図１０は内断熱構造の建物とした場合の使用例における結露の発生を示す図表をそれぞれ示す。
１）図１の如く、本発明の建築下地材Ａは、発泡プラスチック（発泡倍率４０％〜６０％程度とし、軽量化、強度性、肉厚等と、使用用途等を考慮して、決定する）、軽量ボード等の断熱ボード１と、この断熱ボード１の上面には樹脂モルタル材料、接着性モルタル材料等の薄地のモルタル層２を設け、この薄地のモルタル層２に添着するようにグラスファイバーメッシュ３が設けられる。そして、このメッシュ３の周辺部３００は、この断熱ボード１の周辺部１００より内側に位置し、この両周辺部間に薄地のモルタル層２を露出して露出薄地のモルタル層２００を設ける。これによりメッシュ３と薄地のモルタル層２及び露出薄地のモルタル層２００により、当該建築下地材Ａの表面Ａ−１が形成されている。
２）この建築下地材Ａを採用して外壁を構築する一例を説明すると、外壁（内壁、床面等）に通気層を備えた（透水性を備えた）防水シート（図示せず）を取付け、断熱ボード１（湿度を通す性質「透湿性」、熱伝導率、曲げ強さ、難燃性等に優れたボード、例えば、ビーズ法ポリスチレンフォーム４号とする）と、薄地のモルタル層２と、メッシュ３とでなる建築下地材Ａを取付ける。この取付け方法は、釘止め、接着等の方法を採用する。このメッシュ３の周辺部３００には、露出薄地のモルタル層２００が形成された状態で、当該建築下地材Ａは、外壁面に取付けられる。この取付けにより、外壁の表面Ａ−１は、メッシュ３と、薄地のモルタル層２と、露出薄地のモルタル層２００とで形成される。そして、この建築下地材Ａには、同様に次の建築下地材Ａ’が隣接するように取付けられる。この建築下地材Ａと建築下地材Ａ’との間には、隣接隙間、即ち、目地Ｂができる。この目地Ｂを確実に塞ぎ、また外壁の脆化（劣化）回避するためにモルタル等を充填する必要と、隣接するメッシュ３、３’間を確実に連繋し、かつ外壁の脆化回避を図るために上塗り材４を塗着する必要があるので、この目地Ｂの隙間Ｃと、隣接する建築下地材Ａの露出薄地のモルタル層２００と、建築下地材Ａ’の露出薄地のモルタル層２００’とを隠蔽するように、目地用メッシュ３”を張付ける（張装する）。その後、このメッシュ３と目地用メッシュ３”との上面にモルタル系、樹脂系の塗料（上塗り材）を塗着する。この際に、メッシュ３と目地用メッシュ３”が露出することから、当該上塗り材４が確実、（薄くても）剥離することなく塗着される。このメッシュ３と目地用メッシュ３”で建物Ｆを囲繞することで、壁全体等のヒビ割れ防止、またこの薄地のモルタル層２と上塗り材４等の衝撃に対する剥離防止等に役立つ利点がある。この上塗り材４は、接着性、弾性に優れたポリマーベースの塗料であれば限定されないので、従来のように特殊な塗料を必要とせず有益である。また本発明は、ホルムアルデヒトの発生率も少なく健康に悪影響を与えないこと、ガン発生率も少ないこと、等有益な塗料である。またこの建築下地材Ａ、建築下地材Ａ’とを使用することで、養生時間の短縮化に寄与できる。そして、本発明の建築下地材Ａ、建築下地材Ａ’は、図６に示すように、建物Ｆの玄関に取付けられる曲面箇所でも、使用できる特性を備えている。この特性は、建築下地材Ａを構成する断熱ボード１の発泡倍率及び／又は断熱ボード１・薄地のモルタル層２の厚み（略４〜５ｍｍ程度）が微妙に影響する。本発明は、この条件をクリアーしており、図４の状態を確保できる。この特性を利用することで、直線形状は勿論、曲面形状でも可能となり、（構築物、内壁、置物、玩具、物等）の分野への適用が可能となり、形状、断熱、又は衝撃等に優れたが構築できる特徴がある。
【００２１】
尚、図７は建物ＤのルーフバルコニーＥへの利用の一例を示す縮尺模式図であり、ルーフバルコニー用の床構成面Ｅ１に建築下地材Ａを順次施工し、必要により、図示しないが、目地にコーキング材を充填及び／又は目地用メッシュを施工する。そして、この建築下地材Ａの上にＦＲＰ、各種のモルタル等の表面部材Ｆを順次施工し、衝撃、防水機能を備えたルーフバルコニーＥを構築する。また図８はベランダＧへの利用の一例を示す縮尺模式図であるが、前述の例に準ずる。そして、図９の例では、建築下地材Ａ、建築下地材Ａ’を使用して、外断熱構造の建物Ｄとした場合の使用例においては結露の発生も皆無であり、快適な住環境が確保できる。また図１０の内断熱構造の建物（図示せず）とした場合の使用例においては結露の発生が生じ、問題となる可能性がある。これらの結露、温度分布、壁厚等の詳細は、図示されている。この図９、図１０を参考の一例として提出する。
３）次に、図３（イ）〜（ト）に示した建築下地材Ａと、建築下地材Ａ’の製造方法を説明すると、断熱ボード１と、この断熱ボード１の上に樹脂モルタル材料、接着性モルタル材料等の下地モルタル０２を、ロール又は手塗り等利用して添加する。このロール手段の例では、スピード化、自動化と、省力化、低コスト化、又は正確性等が期待できる。また手塗り手段では、設備費の低廉化、簡略化等が期待できる。この下地モルタル０２の上に、ロボット又は手置き等の手段を利用してメッシュ３を添着する。このロボット手段の例では、スピード化、自動化と、省力化、低コスト化、又は正確性等が期待できる。また手置き手段では、設備費の低廉化、簡略化等が期待できる。そして、このメッシュ３を添着する際に、メッシュ３の周辺部３００は、この断熱ボード１の周辺部１００より内側に位置した状態で設ける。この方法により、例えば、後述するスクレパーによる余分のモルタルの除去と、スクレパーの破損等の事故回避、又は施工時の手間、煩雑化等の回避に役立つこと、或いは搬送時の手間、煩雑化等の回避に役立つこと、等の利点がある。このメッシュ３の上に樹脂モルタル材料、接着性モルタル材料等の表面モルタル００２（上塗モルタル）を、前述と同様な方法で添加し、この断熱ボード１、下地モルタル０２、及びメッシュ３、表面モルタル００２でなる四層構造の建築下地素材０Ａが成形される。この建築下地素材０Ａを、圧延ロールＨ、Ｈ間を通過させる。そして、この圧延ロールＨ、Ｈ間を通過させる前にスクレパーＩ（排除手段の一例）を利用して予め余分の表面モルタル０００２を除くことが好ましいが一例である。その後、この圧延ロールＨ、Ｈ間を通過する過程で、略１５〜３５ｋｇ程度の圧力により加圧し（圧縮し）、前記下地モルタル０２、又は表面モルタル００２を所定の厚みに圧縮し、薄地のモルタル層２とするとともに（余分の表面モルタル０００２−１を排除する）、建築下地素材０Ａの両側面よりはみ出しモルタル００００２を、スクレパーＪ、Ｊを利用して取り除く。この作業により、薄地のモルタル層２が成形されるとともに、この薄地のモルタル層２の上面にメッシュ３が位置する構成となった建築下地材Ａが製造できる。そして、この建築下地材Ａの表面は、メッシュ３と、薄地のモルタル層２とで構成される。
【００２２】
尚、図示しないが室内の床材、壁、間仕切り等として、この建築下地材Ａを施工し、その上に畳、床構成材、カーペット等の床構成材、又は壁材等を施工する。この例では、断熱効果、衝撃・音等の吸収機能と、転倒による怪我、損傷等の回避等に役立つこと、又は物の損傷等の回避が図れること、等の実益がある。
【００２３】

Fig. 4, Fig. 4 is a side view of the building base material folded, Fig. 5 is a bird's-eye view explaining the construction state, Fig. 6 is a schematic diagram showing an example of use for a building entrance, and Fig. 7 is a roof. FIG. 8 shows a reduced scale schematic diagram showing an example of use on a balcony, and FIG. 8 shows a reduced scale schematic diagram showing an example of use on a veranda. Further, FIG. 9 is a chart showing the occurrence of condensation in an example of use when the building has an outer heat insulation structure, and FIG. 10 is a chart showing the occurrence of condensation in an example of use when the building is an inner insulation structure.
1) As shown in FIG. 1, the building base material A of the present invention is determined by taking into account foamed plastic (foaming ratio of about 40% to 60%, weight reduction, strength, thickness, usage, etc. ) A heat-insulating board 1 such as a lightweight board, and a thin mortar layer 2 such as a resin mortar material and an adhesive mortar material provided on the upper surface of the heat-insulating board 1, and glass fiber so as to be attached to the thin mortar layer 2 A mesh 3 is provided. And the peripheral part 300 of this mesh 3 is located inside the peripheral part 100 of this heat insulation board 1, and exposes the thin mortar layer 2 between these peripheral parts, and provides the exposed thin mortar layer 200. Thus, the surface A-1 of the building base material A is formed by the mesh 3, the thin mortar layer 2 and the exposed thin mortar layer 200.
2) An example of constructing an outer wall using this building base material A will be explained. A waterproof sheet (not shown) provided with a ventilation layer (with water permeability) is attached to the outer wall (inner wall, floor surface, etc.). , A heat insulating board 1 (a board excellent in moisture-permeable property “moisture permeability”, thermal conductivity, bending strength, flame retardancy, etc., for example, beaded polystyrene foam No. 4), and a thin mortar layer 2 The building base material A consisting of the mesh 3 is attached. This attachment method employs a method such as nail fastening or adhesion. The building foundation material A is attached to the outer wall surface in a state in which the exposed thin mortar layer 200 is formed on the peripheral portion 300 of the mesh 3. By this attachment, the surface A-1 of the outer wall is formed by the mesh 3, the thin mortar layer 2, and the exposed thin mortar layer 200. And similarly to this building base material A, it attaches so that the next building base material A 'may adjoin similarly. An adjacent gap, that is, a joint B is formed between the building base material A and the building base material A ′. Necessary to fill the joint B and to prevent embrittlement (deterioration) of the outer wall, it is necessary to fill with mortar and the like, and the adjacent meshes 3 and 3 'are reliably connected and the embrittlement of the outer wall is avoided. Therefore, it is necessary to apply the top coat material 4 for this purpose. Therefore, the gap C of the joint B, the exposed thin mortar layer 200 of the adjacent building base material A, and the exposed thin ground mortar layer 200 ′ of the building base material A ′.

At this time, since the mesh 3 and the joint mesh 3 ″ are exposed, the overcoat 4 is surely applied without peeling (even if it is thin). Surrounding F has advantages such as prevention of cracking of the entire wall and the like, and prevention of peeling of the thin mortar layer 2 and top coating material 4 against impacts. Since the top coat 4 is not limited as long as it is a polymer-based paint excellent in adhesiveness and elasticity, it is useful without requiring a special paint as in the prior art.
