Description

【0001】
【発明の属する技術分野】
この発明は、床下空間を有しない建物の断熱基礎に使用される断熱材の内部を白アリが通過して軸組や床組へ侵入するのを物理的に防止する建物の防蟻構造に関する。
【0002】
【従来の技術】
建物における従来の白アリ防除技術としては、例えば、(1) 建物の床下の地盤(土壌)と、地面から1m以内の木部とを薬剤で処理する方法や、(2) 白アリの活動をモニタリングしながら、侵入してきた白アリに少量の薬剤を含む毒餌を摂食させて根絶するベイト工法(レスケミカル法)等が知られている。
【0003】
しかしながら、上記のような従来例(1) においては、薬剤に起因する化学物質過敏症等の問題があり、即ち、建物内の環境が化学物質によって汚染されるという問題点がある。
【0004】
また、従来例(2) においては、白アリに毒餌を摂食させ、コロニー全体の活力を衰退させることを目的とするので、その開始から終了までに少なくとも数カ月〜2年程度の長期間を要するという問題点がある。
【0005】
そこで、これらの問題が発生しないように、(3) 薬剤を全く使用しない、ステンレスメッシュや破砕石等の物理的なバリアーを構築する物理的工法(ケミカルフリー法)等が提案されている。この物理的工法に使用されるバリアー材としては、例えば、特許第2652902号公報及び特表平8−506868号公報に開示されているように、白アリの分泌物に耐性で且つ少なくとも約70のショア硬度を有する耐腐食性材料の編み目シートからなり、この編み目の孔がいずれの方向においても制御すべき白アリ種の頭部横断面の最大寸法より小径である白アリバリアー材等がある。
【0006】
【発明が解決しようとする課題】
しかしながら、上記のような従来例(3) においては、断熱基礎等に使用される断熱材の内部を白アリが通過するのを防止することについては開示されていない。
【0007】
この発明は、以上のような問題点に鑑みてなされたものであり、断熱基礎に使用される断熱材の内部を白アリが通過して軸組や床組へ侵入するのを物理的に防止できる建物の防蟻構造を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するための手段とするところは、に、外周部分に施工された布基礎と、この布基礎の内方に盛り上げられる盛土上に前記布基礎の天端面とその上面とがほぼ同じ高さとなるように施工される土間床とを有する建物の前記布基礎の立ち上がり部の外側面に密着した断熱材の内部を白アリが通過して軸組及び床組へ侵入するのを物理的に防止する建物の防蟻構造であって、前記断熱材の布基礎に密着しない面のこの布基礎と密着する下縁から少なくとも地上の所定高さまでの範囲を、前記白アリの分泌物に耐性の耐腐食性材料で構成されかつ複数のアンカー孔を有するシート材で被覆し、前記シート材の上縁部で前記断熱材の上面及び布基礎の天端面を被覆すると共に、このシート材の上縁部を前記土間床に取付けたことにある。
【0010】
に、外周部分に施工された布基礎と、この布基礎の内方に盛り上げられる盛土上に前記布基礎の天端面とその上面とがほぼ同じ高さとなるように施工される土間床とを有する建物の前記布基礎の立ち上がり部の内側面に密着した断熱材の内部を白アリが通過して軸組及び床組へ侵入するのを物理的に防止する建物の防蟻構造であって、前記断熱材の布基礎に密着しない面のこの布基礎と密着する下縁から少なくとも前記土間床の下面の高さまでの範囲を、前記白アリの分泌物に耐性の耐腐食性材料で構成されかつ複数のアンカー孔を有するシート材で被覆したことにある。
【0011】
に、前記シート材の上縁部を前記土間床に取付けたことにある。
【0012】
に、前記シート材の下縁部を前記布基礎に取付けたことにある。
【0013】
に、建物の基礎スラブの外側面に密着した断熱材の内部を白アリが通過して、前記基礎スラブ上に設置された軸組及び床組へ侵入するのを物理的に防止する建物の防蟻構造であって、前記断熱材の基礎スラブに密着しない面のこの基礎スラブ又は基礎スラブの下方に施工される捨てコンクリートと密着する下縁から少なくとも外側面の上縁までの範囲を、前記白アリの分泌物に耐性の耐腐食性材料で構成されかつ複数のアンカー孔を有するシート材で被覆したことにある。
【0014】
に、前記シート材の下縁部を前記基礎スラブ又は捨てコンクリートに取付けたことにある。
【0015】
に、前記シート材が可撓性を有することにある。
【0016】
に、前記シート材が、少なくともいずれかの方向において前記白アリの頭部横断面の最大寸法の2倍以下の寸法である複数のアンカー孔を有することにある。
【0017】
【発明の実施の形態】
以下、この発明の実施形態を図面に基づいて説明する。
図1乃至図4に示すように、第1実施形態に係る建物Aの防蟻構造は、例えば、外周部分に施工された布基礎1と盛土2上に施工される土間床3とを有する床下空間のない建物Aの前記布基礎1の立ち上がり部4の外側面4aに密着した断熱材5の内部を白アリ6が通過して軸組B及び床組Cへ侵入するのを物理的に防止するものであって、前記断熱材5の布基礎1に密着しない外側面5aのこの布基礎1と密着する下縁5fから地上の所定高さLまでの範囲を、前記白アリ6の分泌物に耐性の耐腐食性材料で構成された例えばステンレスメッシュ(シート材)7で被覆すると共に、このステンレスメッシュ7の下縁部7bを前記布基礎1に取付けたものである。
【0018】
前記布基礎1は、建物Aの外周部分に平面視で例えば矩形状等に施工され、図1及び図2に示すように、立ち上がり部4とベース部8とから横断面が例えば逆T字状に形成されている。なお、布基礎1の内方には、この実施形態のような間仕切基礎等の布基礎9と共に又は布基礎9に代えて、独立基礎等を設けておいてもよい。
【0019】
前記土間床3は、布基礎1の内方に周囲の地盤面10aより高く盛り上げられた盛土2上に、布基礎1の天端面1cとその上面3cとがほぼ同じ高さとなるように施工されている。なお、盛土2上には、この実施形態のような目つぶし砂利11の他又は目つぶし砂利11と共に、防湿フィルムや断熱材等を敷設しておいてもよい。断熱材を敷設する場合には、この断熱材の下面等もステンレスメッシュ7等のシート材で被覆しておくのが望ましい。
【0020】
前記断熱材5は、例えば合成樹脂発泡体等から構成され、前記立ち上がり部4の外側面4aに密着している。なお、この断熱材5は、布基礎1を施工してから立ち上がり部4に接着等してもよいし、あるいは断熱材5を配置してから立ち上がり部4等を打設してもよい。また、この実施形態においては、断熱材5と立ち上がり部4がほぼ同じ高さに形成されているが、これに限定されるものではなく、断熱材5の高さや取付け位置等は必要に応じて適宜変更可能である。断熱材5がベース部8に密着しない場合には、この断熱材5の下面5d等もステンレスメッシュ7等で被覆しておけばよい。
【0021】
前記白アリ6とは、ゴキブリに近縁の社会生活をする不完全変態の昆虫であって、シロアリ目(等翅類)Isopteraの総称である。このような白アリ6としては、例えば、ヤマトシロアリやイエシロアリ等の各種の白アリが挙げられる。また、この白アリ6は、図3に示すように、非変形性の堅い頭部6aを有する一方、比較的柔らかくて弱い体部6bを有している。
【0022】
前記ステンレスメッシュ7は、図4に示すように、白アリ6の分泌物に耐性で且つ少なくとも約70のショア硬度を有する耐腐食性材料であるステンレス鋼ワイヤー7c等から製織されて複数の編み目(アンカー孔)12を有している。このようなステンレスメッシュ7としては、例えば、「ターミーメッシュ(TERMI−MESH)」(商品名、ターミーメッシュ・オーストラリア社製)等を好適に使用することができる。
【0023】
なお、白アリバリアー材として使用されるシート材としては、このようなステンレスメッシュ7に限定されるものではなく、白アリ6から放出されるギ酸等の分泌物に耐性で且つ白アリ6が噛み砕くことができない硬さ、好ましくは少なくとも約70のショア硬度を有すると共に、使用環境下で数十年の耐用年数を有する耐腐食性材料で構成されていれば、種々のものを使用することができる。このようなシート材としては、例えば、セラミックス、ガラス、合成樹脂等の繊維、フィラメント、ストランド等から製織又は製編等されたシートや不織布、あるいは金属板、金属シート等が挙げられる。
【0024】
前記ステンレスメッシュ7等のシート材は、断熱材5に、例えば釘、ビス、ステープル等の止着部材や接着剤、あるいは熱溶着等によってあらかじめ工場等で取付けられるか又は建物Aの建築現場で取付けられる。シート材を釘等の止着部材で取付ける場合には、必要に応じてこの止着部材を例えば銅、亜鉛、黄銅等で構成したり、あるいは含有させたりして、白アリ忌避効果を発揮させるようにしておいてもよい。
【0025】
ここで、シート材がステンレスメッシュ7等のように可撓性を有する場合には、建築現場での賦形等が可能であるので、シート材を建築現場で取付ける際の施工が簡単であるという利点がある。なお、可撓性を有しない場合には、工場生産等により、シート材を取付けようとする断熱材5の所定箇所の形状に合わせてあらかじめ適宜の形状に製造しておけばよい。
【0026】
また、シート材が前記編み目12等の複数のアンカー孔を有する場合には、断熱材5にシート材を接着又は熱溶着等する際に、アンカー効果によりこれらをより強固に一体化できるという利点がある。なお、複数のアンカー孔を有するシート材としては、前記ステンレスメッシュ7の他、例えばアンカー孔を打ち抜いて形成したパンチングメタル等が挙げられる。
【0027】
この場合、アンカー孔の寸法が、少なくともいずれかの方向において前記白アリ6の頭部6aの横断面の最大寸法Hの2倍以下である時には、白アリ6の頭部6aが通り抜けないか又は頭部6aが通り抜けても柔らかい体部6b等がアンカー孔に接触するような寸法であり、白アリ6がそれを嫌うので、白アリ6がシート材を通り抜けるのを阻止することができる。また、アンカー孔の寸法を比較的大きくできるので、シート材の材料コストを低減化できると共に、寸法精度も低くてよいために製造も簡単であるという利点がある。
【0028】
なお、前記最大寸法Hは、例えばイエシロアリの職蟻で1.1〜1.25mm程度、ヤマトシロアリの職蟻で1.0〜1.2mm程度であるので、ヤマトシロアリが生息する地域では、アンカー孔の寸法を少なくともいずれかの方向において2.4mm程度以下としておくのが望ましい。このアンカー孔の形状は特に限定されるものではなく、矩形状や円状等の適宜の形状とすることができる。要するに、アンカー孔の寸法が、いずれか一方向、あるいは2以上の方向において2H以下であればよい。
【0029】
ここで、シート材がステンレスメッシュ7等のメッシュ状部材である場合には、その繊維、フィラメント、又はストランド等の数を少なくできるので、コストダウンをより効果的に図ることができるという利点がある。
【0030】
また、アンカー孔の寸法が2Hを超えるが3H以下である場合には、シート材に、少なくともセメントと細骨材とを含有する例えばモルタルや接着セメント等の表面材を塗布しておけば、前記細骨材等により白アリ6の通り抜けを阻止することができる。アンカー孔の寸法が3Hを超える場合には、表面材を塗布しておいても白アリ6が通り抜ける可能性があるので好ましくない。なお、2H以下の場合でも、表面材を塗布しておいても差し支えない。
【0031】
前記表面材には、強度、耐クラック性、接着性、水密性、耐摩耗性等を向上させるために、前記接着セメントに含有されるセメント接着剤等のポリマーを添加しておくのが望ましく、また、必要に応じて例えば亜鉛や銅、あるいは亜鉛化合物や銅化合物等の白アリ忌避剤を添加しておいてもよい。この表面材は、断熱材5にシート材を接着又は熱溶着等して一体化してから塗布してもよいし、あるいは断熱材5にこの表面材でシート材を接着してもよい。
【0032】
このように、床下空間を有しない建物Aにおいて、断熱材5の布基礎1に密着しない面のこの布基礎1と密着する下縁5fから少なくとも地上の所定高さLまでの範囲をステンレスメッシュ7等のシート材で被覆しておけば、光等に弱いために地盤10中から断熱材5に侵入しようとする白アリ6の進行を阻止することができる。そのため、断熱材5を白アリ6による食害から保護できると共に、白アリ6がこの断熱材5の内部を通過して軸組Bや床組Cへ侵入するのを防止できるという利点がある。また、布基礎1の内方の盛土2上に土間床3が施工されているので、布基礎1の内方から白アリ6が侵入しにくいという利点がある。
【0033】
また、この実施形態のように、ステンレスメッシュ7等の下縁部7bを例えば接着セメント13等でベース部8上等に接着しておけば、シート材と布基礎との間に隙間が形成されないので、白アリ6の侵入を確実に防止できるという利点がある。
【0034】
この場合、前記下縁部7bは、図5に示すように断熱材5の下端を巻き込むようにして布基礎1に接着等しておいてもよいし、あるいは図6に示すように内方に突出した状態で布基礎1に埋設しておいてもよい。また、図7に示すように、下方に突出した状態で布基礎1に埋設しておいてもよい。要するに、接着又は埋設等することによって、布基礎1の所定箇所の表面又は内部に取付けておけばよい。なお、接着する場合には、必要に応じて接着前に釘等の止着部材で仮止めしてもよいし、前記接着セメント13に代えて、例えばモルタル等を使用してもよい。
【0035】
更に、シート材の被覆範囲もこの実施形態に限定されるものではなく、図7に示すように断熱材5の外側面5aの全体を被覆しておいてもよいし、あるいは図8に示すように更に断熱材5の上面5cを被覆しておいてもよい。また、図8のように、シート材の上縁部7aを、断熱材5と立ち上がり部4の厚さの和とほぼ同じ間隔を開けてコ字状に折曲しておけば、シート材を後から取付ける場合において位置決めが簡単であると共に、固定するまでのずれも防止できるという利点がある。この場合、前記上縁部7aの水平部分は、土台14と立ち上がり部4の間に介在する気密パッキン15の下に挟んで固定すればよい。このように、断熱材5の上面5cをも被覆しておけば、万が一断熱材5の内部に白アリ6が侵入した場合でも、シート材により白アリ6の進行が阻止されて上方の軸組Bや床組Cへ侵入することがない。また、この場合、シート材の上縁部7aを気密パッキン15の下に挟んでおけば、断熱材5と立ち上がり部4の間に隙間が形成されている時でも、白アリ6の侵入を確実に防止することができる。
【0036】
加えて、図9に示すように、より低く形成した断熱材5の外側面5aに加えて上面5cをステンレスメッシュ7等のシート材で被覆すると共に、この断熱材5の上面5cにシート材を介して更に断熱材16を取付けてもよい。この場合も図8に示す例と同様、万が一下段の断熱材5の内部に白アリ6が侵入した場合でも、シート材により白アリ6の進行が阻止されて上段の断熱材16に侵入することがない。また、図9のように、シート材の上縁部7aの先端を立ち上がり部4に埋設等して取付けておけば、下段の断熱材5と立ち上がり部4の間に隙間が形成されている時でも、白アリ6の侵入を確実に防止することができる。
【0037】
図10に示すように、第2実施形態に係る建物Aの防蟻構造は、第1実施形態において、前記ステンレスメッシュ7の上縁部7aをより長く形成しておき、この上縁部7aで断熱材5の上面5c及び布基礎1の天端面1cを被覆すると共に、この上縁部7aを土間床3の上面3cに接着セメント13等で取付けたものである。
【0038】
なお、この場合も、前記上縁部7aは、適当な角度で下方へ折曲等しておいて土間床3の打設の際にこの土間床3に埋設してもよい。
【0039】
このようにして前記上縁部7aを土間床3に取付けておけば、土間床3と立ち上がり部4の打ち継ぎ部分17から白アリ6が侵入するのを防止できるという利点がある。
【0040】
図11に示すように、第3実施形態に係る建物Aの防蟻構造は、第1実施形態において、前記断熱材5が立ち上がり部4の内側面4bに密着していると共に、この断熱材5の布基礎1に密着しない例えば内側面5bのこの布基礎1と密着する下縁5fから土間床3の下面3dの高さまでの範囲をステンレスメッシュ7で被覆したものである。
【0041】
上記の範囲をステンレスメッシュ7等のシート材で被覆しておけば、第1及び第2実施形態と同様、地盤10や盛土2等から断熱材5に侵入しようとする白アリ6の進行を阻止することができる。
【0042】
なお、この実施形態においても、断熱材5がベース部8と密着しない場合には、断熱材5の下面5d等をもシート材で被覆しておけばよい。
【0043】
図12に示すように、第4実施形態に係る建物Aの防蟻構造は、第3実施形態において、前記ステンレスメッシュ7の上縁部7aをより長く形成しておき、この上縁部7aを例えば土間床3の下面3d付近に埋設したものである。
【0044】
なお、この場合も、図13に示すように、前記上縁部7aを土間床3の上面3cに接着セメント13等で接着することにより取付けてもよい。
【0045】
このようにして前記上縁部7aを土間床3に取付けておけば、土間床3と断熱材5の打ち継ぎ部分18から白アリ6が侵入するのを防止できるという利点がある。
【0046】
以上の第1乃至第4実施形態においては、前記断熱材5が立ち上がり部4の外側面4a又は内側面4bに密着している場合について説明したが、これに限定されるものではなく、断熱材5が立ち上がり部4の両側面4a,4bにそれぞれ密着していてもよい。また、土間床3と前記布基礎9等の打ち継ぎ部分19の上方又は下方等にも、シート材をこの打ち継ぎ部分19を閉塞するように取付けておくのが望ましい。
【0047】
図14及び図15に示すように、第5実施形態に係る建物Aの防蟻構造は、例えば、床下空間を有しない建物Aの基礎スラブ20の外側面20aに密着した断熱材5の内部を白アリ6が通過して、前記基礎スラブ20上に設置された軸組B及び床組Cへ侵入するのを物理的に防止するものであって、前記断熱材5の基礎スラブ20に密着しない外側面5aの全体をステンレスメッシュ7で被覆すると共に、このステンレスメッシュ7の下縁部7bを基礎スラブ20の下方に施工された捨てコンクリート21の外側面21aに接着セメント13等で取付けたものである。
【0048】
前記基礎スラブ20は、土台14等が載置される部分が他の部分より厚肉に形成されているが、この基礎スラブ20の構成としては特に限定されるものではなく、軸組Bや床組Cを直接設置できる各種の構成のものを採用することができる。また、この基礎スラブ20の下方の所定範囲には、必要に応じて断熱材を敷設しておいてもよい。この場合、敷設される断熱材の下面等もステンレスメッシュ7等で被覆しておくのが望ましい。
【0049】
なお、ステンレスメッシュ7等の下縁部7bは、捨てコンクリート21の打設の際にこの捨てコンクリート21に埋設してもよい。ここで、捨てコンクリート21を施工しない場合には、ステンレスメッシュ7等は、断熱材5の基礎スラブ20に密着しない面のこの基礎スラブ20と密着する下縁から外側面5aの上縁5eまでの範囲を被覆しておけばよい。この場合、ステンレスメッシュ7等の下縁部7bは、基礎スラブ20に接着又は埋設等して取付けておくのが望ましい。
【0050】
このように、基礎スラブ20においても布基礎1の場合と同様、上記の範囲をステンレスメッシュ7等のシート材で被覆しておけば、地盤10中から断熱材5に侵入しようとする白アリ6の進行を阻止することができる。
【0051】
また、この実施形態においてもステンレスメッシュ7等の上縁部7aをより長く形成しておき、この上縁部7aで断熱材5の上面5cをも被覆しておけば、万が一断熱材5の内部に白アリ6が侵入した場合でも、シート材により白アリ6の進行が阻止されて上方の軸組Bや床組Cへ侵入することがない。また、この場合、シート材の上縁部7aを気密パッキン15の下に挟んでおけば、断熱材5と基礎スラブ20の間に隙間が形成されている時でも、白アリ6の侵入を確実に防止することができる。
【0052】
以上の第1乃至第5実施形態においては、断熱材5の外側面5a又は内側面5b等の所定範囲をステンレスメッシュ7等で被覆しているが、これに限定されるものではなく、断熱材5の外側面5a、内側面5b、上面5c、及び下面5dの4面を被覆しておいてもよいし、あるいは横方向に並べて配置される断熱材5の全面を被覆しておいてもよい。
【0053】
【発明の効果】
以上のように、請求項1の発明によれば、布基礎と土間床とを有する床下空間のない建物において、前記断熱材の布基礎に密着しない面のこの布基礎と密着する下縁から少なくとも地上の所定高さまでの範囲を前記シート材で被覆しているので、光等に弱いために地盤中から断熱材に侵入しようとする白アリの進行を阻止することができる。そのため、断熱材を白アリによる食害から保護できると共に、白アリがこの断熱材の内部を通過して軸組や床組へ侵入するのを防止できるという利点がある。また、布基礎の内方の盛土上に土間床が施工されているので、布基礎の内方から白アリが侵入しにくいという利点がある。
【0054】
更に、前記シート材の上縁部で前記断熱材の上面及び布基礎の天端面を被覆すると共に、このシート材の上縁部を前記土間床に取付けているので、土間床と立ち上がり部の打ち継ぎ部分から白アリが侵入するのを防止できるという利点がある。また、万が一断熱材の内部に白アリが侵入した場合でもシート材により白アリの進行が阻止されると共に、断熱材と立ち上がり部の間に隙間が形成されている時でも白アリの侵入を確実に防止することができる。
【0055】
請求項の発明によれば、前記断熱材の布基礎に密着しない面のこの布基礎と密着する下縁から少なくとも前記土間床の下面の高さまでの範囲を前記シート材で被覆しているので、地盤や盛土等から断熱材に侵入しようとする白アリの進行を阻止することができる。
【0056】
請求項の発明によれば、前記シート材の上縁部を前記土間床に取付けているので、土間床と断熱材の打ち継ぎ部分から白アリが侵入するのを防止できるという利点がある。
【0057】
請求項の発明によれば、前記シート材の下縁部を前記布基礎に取付けているので、シート材と布基礎との間に隙間が形成されないので、白アリの侵入を確実に防止できるという利点がある。
【0058】
請求項の発明によれば、基礎スラブ上に軸組や床組が設置された床下空間を有しない建物において、前記断熱材の基礎スラブに密着しない面のこの基礎スラブ又は捨てコンクリートと密着する下縁から少なくとも外側面の上縁までの範囲を、前記シート材で被覆しているので、地盤中から断熱材に侵入しようとする白アリの進行を阻止することができる。
【0059】
請求項の発明によれば、前記シート材の下縁部を前記基礎スラブ又は捨てコンクリートに取付けているので、シート材と基礎スラブ又は捨てコンクリートとの間に隙間が形成されないので、白アリの侵入を確実に防止できるという利点がある。
【0060】
請求項の発明によれば、前記シート材が可撓性を有するので、建築現場での賦形等が可能であり、そのためシート材を建築現場で取付ける際の施工が簡単であるという利点がある。
【0061】
請求項の発明によれば、前記シート材が、少なくともいずれかの方向において前記白アリの頭部横断面の最大寸法の2倍以下の寸法である複数のアンカー孔を有するので、断熱材にシート材を接着又は熱溶着等する際に、アンカー効果によりこれらをより強固に一体化できるという利点がある。また、アンカー孔の寸法が前記最大寸法の2倍以下で、白アリの頭部が通り抜けないか又は頭部が通り抜けても柔らかい体部等がアンカー孔に接触するような寸法であり、白アリがそれを嫌うので、白アリがシート材を通り抜けるのを阻止することができる。また、アンカー孔の寸法を比較的大きくできるので、シート材の材料コストを低減化できると共に、寸法精度も低くてよいために製造も簡単であるという利点がある。

Conventional white ant control techniques in buildings include, for example, (1) a method of treating the ground (soil) under the floor of a building and a xylem within 1 m of the ground with chemicals, and (2) the activity of white ants. A bait method (less chemical method) and the like are known in which white ants that have invaded while eating a poisonous bait containing a small amount of drug are eradicated while monitoring.
[0003]
However, in the conventional example (1) as described above, there is a problem such as chemical hypersensitivity caused by the drug, that is, the environment in the building is contaminated by the chemical substance.

[0006]
[Problems to be solved by the invention]
However, in the conventional example (3) as described above, there is no disclosure about preventing white ants from passing through the inside of the heat insulating material used for the heat insulating foundation or the like.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 4, the ant proof structure of the building A according to the first embodiment is, for example, an underfloor having a cloth foundation 1 constructed on the outer peripheral portion and a dirt floor 3 constructed on the embankment 2. Physically preventing white ants 6 from passing into the shaft group B and the floor group C through the inside of the heat insulating material 5 in close contact with the outer surface 4a of the rising portion 4 of the fabric foundation 1 of the building A having no space. In the range from the lower edge 5f of the outer surface 5a that is not in close contact with the cloth base 1 of the heat insulating material 5 to the cloth base 1 to a predetermined height L on the ground, the secretion of the white ants 6 For example, a stainless mesh (sheet material) 7 made of a corrosion-resistant material resistant to the above-mentioned is used, and a lower edge portion 7b of the stainless mesh 7 is attached to the fabric base 1.
[0018]
The fabric foundation 1 is constructed in a rectangular shape or the like in a plan view on the outer peripheral portion of the building A. As shown in FIGS. 1 and 2, the cross section from the rising portion 4 and the base portion 8 is, for example, an inverted T shape. Is formed. It should be noted that an independent foundation or the like may be provided inside the cloth foundation 1 together with the cloth foundation 9 such as a partition foundation as in this embodiment or instead of the cloth foundation 9.
[0019]
The soil floor 3 is constructed on the embankment 2 raised above the surrounding ground surface 10a inward of the fabric foundation 1 so that the top end surface 1c of the fabric foundation 1 and the upper surface 3c thereof are substantially the same height. ing. In addition to the crushed gravel 11 as in this embodiment or together with the crushed gravel 11, a moisture-proof film, a heat insulating material, or the like may be laid on the embankment 2. When laying a heat insulating material, it is desirable to coat the lower surface of the heat insulating material with a sheet material such as stainless steel mesh 7.
[0020]
The heat insulating material 5 is made of, for example, a synthetic resin foam or the like, and is in close contact with the outer side surface 4 a of the rising portion 4. The heat insulating material 5 may be adhered to the rising portion 4 after the fabric foundation 1 is applied, or the rising portion 4 may be placed after the heat insulating material 5 is disposed. Moreover, in this embodiment, although the heat insulating material 5 and the standup | rising part 4 are formed in the substantially same height, it is not limited to this, The height, attachment position, etc. of the heat insulating material 5 are as needed. It can be changed as appropriate. When the heat insulating material 5 does not adhere to the base portion 8, the lower surface 5d of the heat insulating material 5 may be covered with the stainless mesh 7 or the like.
[0021]
The white ant 6 is an incompletely transformed insect that has a social life closely related to cockroaches, and is a general term for the termite (Isoptera) Isoptera. Examples of such white ants 6 include various white ants such as Yamato termites and moth termites. Further, as shown in FIG. 3, the white ant 6 has a non-deformable hard head 6a, and a relatively soft and weak body 6b.
[0022]
As shown in FIG. 4, the stainless mesh 7 is woven from a stainless steel wire 7c or the like, which is a corrosion-resistant material that is resistant to the secretion of white ants 6 and has a Shore hardness of at least about 70. Anchor hole) 12. As such a stainless steel mesh 7, for example, “TERMI-MESH” (trade name, manufactured by Termy Mesh Australia) or the like can be preferably used.
[0023]
The sheet material used as the white ant barrier material is not limited to the stainless steel mesh 7 as described above, and is resistant to secretions such as formic acid released from the white ants 6 and the white ants 6 chew. Various materials can be used as long as they are composed of a corrosion resistant material that has a hardness that cannot be achieved, preferably a Shore hardness of at least about 70, and has a service life of several decades in the environment of use. . Examples of such a sheet material include sheets and nonwoven fabrics woven or knitted from fibers such as ceramics, glass and synthetic resin, filaments, strands, and the like, or metal plates and metal sheets.
[0024]
The sheet material such as the stainless mesh 7 is attached to the heat insulating material 5 in advance at a factory or the like by a fastening member such as a nail, a screw, or a staple, an adhesive, or heat welding. It is done. When attaching a sheet material with a fastening member such as a nail, the fastening member is composed of, for example, copper, zinc, brass, or the like, if necessary, and exhibits a white ant repellent effect. You may keep it.
[0025]
Here, when the sheet material is flexible like the stainless mesh 7 or the like, it can be shaped at the construction site, so that it is easy to install the sheet material at the construction site. There are advantages. In addition, when it does not have flexibility, what is necessary is just to manufacture in an appropriate shape beforehand according to the shape of the predetermined location of the heat insulating material 5 which is going to attach a sheet material by factory production etc.
[0026]
Further, when the sheet material has a plurality of anchor holes such as the stitches 12, when the sheet material is bonded or heat welded to the heat insulating material 5, there is an advantage that these can be more firmly integrated by an anchor effect. is there. Examples of the sheet material having a plurality of anchor holes include, in addition to the stainless mesh 7, for example, punching metal formed by punching anchor holes.
[0027]
In this case, when the dimension of the anchor hole is not more than twice the maximum dimension H of the cross section of the head 6a of the white ant 6 in at least any direction, the head 6a of the white ant 6 does not pass through or Even if the head 6a passes through, the size is such that the soft body 6b and the like come into contact with the anchor hole, and the white ants 6 dislike it, so that the white ants 6 can be prevented from passing through the sheet material. Further, since the size of the anchor hole can be made relatively large, it is possible to reduce the material cost of the sheet material, and there is an advantage that the manufacturing is easy because the dimensional accuracy may be low.
[0028]
The maximum dimension H is, for example, about 1.1 to 1.25 mm for termite ants, and about 1.0 to 1.2 mm for termite ants. In the area where Yamato termites live, It is desirable that the size of the hole be about 2.4 mm or less in at least any direction. The shape of the anchor hole is not particularly limited, and may be an appropriate shape such as a rectangular shape or a circular shape. In short, the dimension of the anchor hole may be 2H or less in any one direction or two or more directions.
[0029]
Here, when the sheet material is a mesh-like member such as a stainless mesh 7, the number of fibers, filaments, strands, or the like can be reduced, so that there is an advantage that the cost can be reduced more effectively. .
[0030]
Further, when the dimension of the anchor hole exceeds 2H but is 3H or less, if a surface material such as mortar or adhesive cement containing at least cement and fine aggregate is applied to the sheet material, The passage of the white ants 6 can be prevented by the fine aggregate or the like. When the dimension of the anchor hole exceeds 3H, the white ants 6 may pass through even if the surface material is applied, which is not preferable. Even in the case of 2H or less, a surface material may be applied.
[0031]
In order to improve the strength, crack resistance, adhesion, water tightness, wear resistance, etc., it is desirable to add a polymer such as a cement adhesive contained in the adhesive cement to the surface material, Moreover, you may add white ant repellents, such as zinc, copper, or a zinc compound, a copper compound, as needed. The surface material may be applied after the sheet material is integrated with the heat insulating material 5 by bonding or heat welding, or the surface material may be bonded to the heat insulating material 5 with the surface material.
[0032]
In this way, in the building A having no underfloor space, the stainless steel mesh 7 covers a range from the lower edge 5f in close contact with the fabric foundation 1 of the surface of the heat insulating material 5 to the fabric foundation 1 to at least the predetermined height L on the ground. If it coat | covers with sheet | seat materials etc., since it is weak to light etc., the progress of the white ant 6 which tries to penetrate | invade the heat insulating material 5 from the ground 10 can be blocked | prevented. Therefore, there is an advantage that the heat insulating material 5 can be protected from the damage caused by the white ants 6 and the white ants 6 can be prevented from passing through the inside of the heat insulating material 5 and entering the shaft set B or the floor set C. Moreover, since the interstitial floor 3 is constructed on the embankment 2 inside the cloth foundation 1, there is an advantage that the white ants 6 do not easily enter from the inside of the cloth foundation 1.
[0033]
Further, as in this embodiment, if the lower edge portion 7b of the stainless mesh 7 or the like is bonded to the base portion 8 or the like with, for example, adhesive cement 13 or the like, no gap is formed between the sheet material and the fabric foundation. Therefore, there is an advantage that the white ants 6 can be reliably prevented from entering.
[0034]
In this case, the lower edge portion 7b may be adhered to the cloth base 1 so as to wind the lower end of the heat insulating material 5 as shown in FIG. 5, or inward as shown in FIG. It may be embedded in the fabric foundation 1 in a protruding state. Moreover, as shown in FIG. 7, you may embed in the fabric foundation 1 in the state protruded below. In short, what is necessary is just to attach to the surface or the inside of the predetermined location of the fabric foundation 1 by adhesion | attachment or embedding. In the case of bonding, if necessary, it may be temporarily fixed with a fastening member such as a nail before bonding, or a mortar or the like may be used instead of the bonding cement 13.
[0035]
Further, the covering range of the sheet material is not limited to this embodiment, and the entire outer surface 5a of the heat insulating material 5 may be covered as shown in FIG. 7, or as shown in FIG. Further, the upper surface 5c of the heat insulating material 5 may be covered. Further, as shown in FIG. 8, if the upper edge portion 7a of the sheet material is bent in a U-shape with substantially the same interval as the sum of the thickness of the heat insulating material 5 and the rising portion 4, the sheet material is In the case of later mounting, there are advantages that positioning is easy and displacement until fixing can be prevented. In this case, the horizontal portion of the upper edge portion 7 a may be fixed by being sandwiched under the hermetic packing 15 interposed between the base 14 and the rising portion 4. Thus, if the upper surface 5c of the heat insulating material 5 is also covered, even if the white ants 6 intrude into the heat insulating material 5, the white ants 6 are prevented from advancing by the sheet material, and the upper shaft assembly No intrusion into B or floor set C. Further, in this case, if the upper edge portion 7a of the sheet material is sandwiched between the airtight packing 15, even when a gap is formed between the heat insulating material 5 and the rising portion 4, the white ants 6 can surely enter. Can be prevented.
[0036]
In addition, as shown in FIG. 9, in addition to the outer surface 5a of the heat insulating material 5 formed lower, the upper surface 5c is covered with a sheet material such as a stainless mesh 7, and a sheet material is applied to the upper surface 5c of the heat insulating material 5. Further, a heat insulating material 16 may be attached. In this case as well, as in the example shown in FIG. 8, even if the white ants 6 intrude into the lower insulating material 5, the white ants 6 are prevented from advancing by the sheet material and enter the upper insulating material 16. There is no. Further, as shown in FIG. 9, if the tip of the upper edge portion 7 a of the sheet material is embedded in the rising portion 4 and attached, a gap is formed between the lower heat insulating material 5 and the rising portion 4. However, the invasion of the white ants 6 can be surely prevented.

[0038]
In this case as well, the upper edge portion 7a may be bent downward or the like at an appropriate angle and embedded in the interstic floor 3 when the interstic floor 3 is placed.
[0039]
If the upper edge portion 7a is attached to the floor 3 in this manner, there is an advantage that the white ants 6 can be prevented from entering from the joint portion 17 of the floor 3 and the rising portion 4.
