Description

【０００１】
【発明の属する技術分野】
本発明は、基礎の上面に沿って配置され且つ柱との接続が容易な建物用土台に関する。尚、本明細書において、基礎は、布基礎、べた基礎、または独立基礎などを含む。
【０００２】
【従来の技術】
一般に、コンクリートからなる基礎の上面に沿って固定される建物用土台には、在来工法やプレハブ工法においても、断面角形の木材からなる土台が広く用いられている。かかる木材製の土台は、基礎の上方に突出するアンカーボルトにより固定されると共に、柱や間柱などもかかる土台を介して立設されている（例えば、特許文献１参照）。
【０００３】
しかしながら、従来の木材製の建物用土台には、以下のような問題があった。
（１）白蟻による食害を受け易く、湿気によって腐食し易い。
（２）吸湿および放湿を繰り返すことにより、土台の断面寸法が経年変化するため、建物に歪みを招来させる。
（３）重量が大きいため、現場での作業性が低く、コスト高になり易い。
（４）柱の直下などの集中荷重を支持する部分とそうでない部分との何れも同一断面であるため、重量が重くなり、当該土台材料の無駄にもなる。
（５）加工精度が低く且つ寸法が狂いやすいため、モジュールユニット化が困難で建物の施工性が低下する。
（６）柱などとの接合部に複雑で熟練を要する仕口構造の加工が必要となる。
（７）木材伐採による環境破壊につながり易い。

【発明が解決すべき課題】
本発明は、以上に説明した従来の技術における問題点を解決し、白蟻の食害や湿気による腐食や寸法変化がなく、軽量で加工精度および施工性を高められると共に、柱との接続も容易となる建物用土台を提供する、ことを課題とする。
【０００６】
【課題を解決するための手段および発明の効果】
本発明は、上記課題を解決するため、発明者らによる鋭意研究および調査の結果、建物用土台にアルミニウム合金からなる複数の押出形材を用い、且つこの土台本体の上面に上向きに開口する凹溝を形成するか、あるいは、土台本体の上面の一部を切除することにより上向きに開口する凹溝を形成し、この凹溝を利用することにより柱を支持する支持体を固定する、ことに着想して成されたものである。
即ち、本発明の建物用土台は、基礎の上面に沿って配置され且つ上向きに開口する凹溝を含む土台本体と、柱立設位置の直下で上記土台本体の凹溝の開口部を覆い且つ上面に柱の下端に設けたスリットに挿入する垂直片を立設している支持体と、を含み、上記土台本体は、アルミニウムまたはアルミニウム合金からなり所定の断面形状を有する押出形材を、それらの押出方向に沿ってそれぞれの所定長さで切断したものである、ことを特徴とする。
【０００７】
これによれば、アルミニウム合金などからなる押出形材により建物用土台を形成するため、白蟻の食害や湿気による腐食または寸法変化がなく、長期間にわたり断面や形状および強度が安定した土台となる。また、土台を軽量化できるため、加工精度が高く且つ建物の施工性を高められると共に、環境上からも好ましくなる。しかも、柱を立設する位置には、支持体を配置することにより、その垂直片を柱のスリットに挿入して、係る柱を垂直に接続して支持することができる。尚、上記押出形材には、押出成形した状態（生地材）である形態の他、表面に陽極酸化皮膜と塗装とを施した形態も含まれる。また、上記柱には、隅柱や管柱のほか、間柱や竪枠も含まれる。ここで、凹溝は、土台本体の全長にわたって形成されたものであってもよく、土台本体の一部に形成されたものであってもよい。
【０００８】
また、本発明には、前記土台本体は、前記基礎の上面に固定される底片と当該底片上の左右両側に断面矩形の一対の中空角形部とを有すると共に、係る一対の中空角形部および上記底片の間に前記凹溝が位置している、建物用土台（請求項１）も含まれる。
これによれば、土台本体は、底片上の左右に一対の中空角形部を有しているため、その凹溝を前記支持体または次述するカバーに覆われた後、前記柱や壁などの建築部材が上方に配置されても、これらを確実に支えることが可能となる。
更に、本発明には、前記土台本体の上向きに開口する凹溝には、柱立設位置の以外の位置において上記凹溝の開口部を覆う前記同様の押出形材からなるカバーが取り付けられる、建物用土台（請求項２）も含まれる。
加えて、本発明には、前記カバーは、前記土台本体の凹溝に嵌合される断面ほぼ下向きのコ字形を呈し、その水平片が上記土台本体における一対の中空角形部の上面と面一になる、建物用土台（請求項３）も含まれる。
これらによれば、土台本体の凹溝の開口部を閉塞し且つ土台本体の底片を固定するアンカーボルトやナットを外部から遮蔽し且つ防護することができる。
【０００９】
また、本発明には、前記土台本体の上向きに開口する凹溝は、前記押出形材の上面を前記支持体の長さ分だけ切除することにより形成される、建物用土台（請求項４）も含まれる。
これによれば、前述のカバーを取り付ける必要がなくなるので、部品点数が少なく、設置作業の簡略化を図ることができる。
【００１０】
また、本発明には、前記支持体は、前記垂直片に前記柱の下部を貫通するピンを貫通させるピン孔を開設している、建物用土台（請求項５）も含まれる。
これによれば、垂直片がスリットに挿入されて立設する柱に対し、これを抜き出す上向きの力が加わっても、上記ピンの剪断抵抗により、十分に対向することができる。例えば、建物の柱や壁などの上部構造体が、台風などで負圧を受けても、上記ピンにより柱が抜け出さないため、かかる建物の倒壊を防ぐことが可能となる。尚、ピンおよびこれを貫通させる垂直片のピン孔は、挿入片の中央付近に１個のみ、あるいは複数個を適所に形成しも良い。また、垂直片のピン孔は、前記柱の他に筋交いなどの下端部を固定するために活用することも可能である。
【００１１】
更に、前記支持体は、前記土台本体の凹溝に嵌合される断面矩形の矩形部を有し、係る矩形部の上面に前記垂直片が立設している、建物用土台（請求項６）も本発明に含まれる。これによれば、支持体の矩形部を土台本体の凹溝内に嵌合することにより、係る凹溝の開口部を覆うと共に当該支持体の垂直片を土台本体の上方に強固に立設することが可能となる。
また、本発明には、前記支持体は、前記矩形部の上面から左右に延び且つ前記土台本体の各中空角形部の上面に載置される一対のフランジを有する、建物用土台（請求項７）も含まれる。これによれば、上記フランジを土台本体の中空角形部に接触させることにより、土台本体の凹溝内に矩形部を嵌合した支持体を、係る土台本体の上に安定して配置することができる。
【００１２】
更に、本発明には、前記支持体は、前記基礎の上面から突出するアンカーボルトに固定される、建物用土台（請求項８）も含まれる。
これによれば、支持体が基礎に埋設されたアンカーボルトに直接固定されるので、その取付強度が非常に高く、この支持体に固定される柱を確実に支持することが可能となる。
加えて、本発明には、前記支持体は、前記矩形部の上面における前記垂直片の長手方向の両側にナット締め付け具挿入用で大径の通し孔を有すると共に、係る通し孔の直下に位置する上記矩形部の底面に前記アンカーボルト貫通用で細径の貫通孔を有する、建物用土台（請求項９）も含まれる。
これによれば、基礎の上面から土台本体の底片を貫通したアンカーボルトを上記貫通孔から支持体の矩形部内に挿入できると共に、上記ボルトの雄ネジ部に締結するナットを、上記通し孔から矩形部内に挿入した例えばボックススパナなどにて締結できる。これにより、支持体は、柱立設位置の直下で、土台本体と共に基礎上に固定することができる。従って、柱を確実に支持することが可能となる。尚、上記長手方向とは、支持体の押出方向であり且つ土台の長手方向である。
【００１３】
また、本発明には、前記支持体は、垂直片と当該垂直片の長手方向の両側または片側に延長して形成される矩形部とにより形成されると共に、その延長部に、前記アンカーボルト貫通用の貫通孔が形成されている、建物用土台（請求項１０）も含まれる。
これによると、土台本体と支持体とを同時に基礎上に固定することができるので、施工効率が非常に高いものとなる。
【００１４】
さらに、本発明には、前記支持体は、垂直片部分と矩形部部分とが一体に形成されたアルミニウムまたはアルミニウム合金からなる押出形材を、その押出方向に沿ってそれぞれの所定長さで切断すると共に、前記垂直片部分を適宜切除して形成されてなる、建物用土台（請求項１１）も含まれる。
これによれば、溶接等により矩形部と垂直片とを一体にする場合に比べて、その寸法精度を格段に向上させることができるので、結果として歪の少ない建物を構築することが可能となる。
【００１５】
【発明の実施の形態】
以下において、本発明の実施に好適な形態を図面と共に説明する。
図１は、本発明による１形態の建物用土台１０の使用状態を示す。
建物用土台１０は、図１に示すように、基礎（布基礎）１の上面２に沿って配置され、当該基礎１中にアンカー部が埋設された後述するアンカーボルトにより固定される。係る建物用土台１０は、基礎１の上面２に複数のスペーサ３を介して固定される長尺な土台本体１２と、その凹溝１３の開口部を覆い且つ柱４０の立設位置以外の位置に配置するカバー２０と、柱４０の立設位置のほぼ直下に位置し上記凹溝１３を覆い且つ柱４０のスリット４４に挿入する垂直片３８を立設する支持体３０と、から構成されている。
【００１６】
土台本体１２は、図２（Ａ）に示すように、アルミニウム合金（例えばＪＩＳ：Ａ６０６３Ｓ−Ｔ５、またはＡ６０６１Ｓ−Ｔ６）からなる押出形材を、その押出方向（図示で奥行き方向）と直交して所定の長さで切断したものである。
即ち、図２（Ａ）に示すように、土台本体１２は、基礎１の上面２に載置したスペーサ３上に載置される底片１４と、この底片１４上の左右両側に断面矩形の一対の中空角形部１５と、これらの間に位置し且つ上向きに開口する凹溝１３と、を長手（押出）方向（図示で奥行き方向）に沿って一体に有する。尚、上記スペーサ３は、合成ゴムまたは合成樹脂などからなる厚さ約２０ｍｍのシートである。
上記底片１４は、図２（Ａ）で右側の建物屋内側に凸条１４ａを連続して水平に突出させ、各中空角形部１５は、断面ほぼ正方形の中空部１６を内設すると共に、図２（Ａ）で左側の屋外側の上隅部に凸条１８を垂直に設け、図２（Ａ）で右側の屋内側の上隅部に断面Ｌ字形の凸条１９を設けている。
因みに、土台本体１２の寸法は、幅１６０ｍｍで且つ高さ４０ｍｍである。但し、その高さは例えば８０ｍｍなどのように更に高くしても良い。
【００１７】
また、カバー２０も前記同様の押出形材を所定の長さで切断したもので、図２（Ａ）に示すように、厚肉部２２ａを有する水平片２２と、その両端から垂下した一対の縦片２４と、これらに囲まれた凹部２８と、からなる断面ほぼ下向きコ字形を呈し、各縦片２４の内側面には、リブ２６，２６が対称に突設されている。
図１，図２（Ａ）に示すように、基礎１の上面２に配置したスペーサ３，３の中央には、当該基礎１中に図示しないアンカー部を埋設したアンカーボルト４が貫通し、係るボルト４の雄ネジ部５は、スペーサ３上に載置した土台本体１２の底片１４に設けた透孔（図示せず）を貫通し、当該土台本体１２の凹溝１３内に位置する。この雄ネジ部５に座金６を通し、ナット８を締結することにより、土台本体１２は、基礎１の上面２に沿って固定される。
【００１８】
図２（Ｂ）に示すように、基礎１上に固定された土台本体１２の凹溝１３内に、カバー２０を下向きに叩き込むと、係るカバー２０の縦片２４，２４は、当該凹溝１３内に挿入して嵌合する。この結果、カバー２０の水平片２２の上面２３と上記本体１２の各中空角形部１５の上面１７とは面一になると共に、係るカバー２０により凹溝１３の開口部が覆われる。
これにより、アンカーボルト４の雄ネジ部５やナット８などは、カバー２０により外部から覆われ且つ保護される。尚、カバー２０の各リブ２６は、図２（Ｂ）の嵌合状態で、各縦片２４の曲げ変形や捻り変形などを抑制している。
【００１９】
図１に示すように、木材製の角材からなる柱４０を立設する予定位置のほぼ直下には、基礎１上に固定された土台本体１２の凹溝１３を覆い且つ係る柱４０を支持する支持体３０が両側のカバー２０，２０間に挟まれて配置される。
支持体３０も、前記同様の押出形材を所定の長さで切断し且つ切り欠き加工したもので、図３（Ａ）に示すように、前記土台本体１２の凹溝１３内に嵌合される矩形部３２と、係る矩形部３２の上面３３の両側から水平に延びる左右一対のフランジ３６と、矩形部３２の上面３３にて内外方向の中央から垂直に立設する厚肉の垂直片３８と、を長手（押出）方向（図示で奥行き方向）に沿って一体に有する。尚、矩形部３２は、やや厚肉で且つ相似形の中空部３２ａを内蔵している。
【００２０】
図３（Ａ）に示すように、支持体３０における矩形部３２の底面３４には、土台本体１２の底片１４を貫通したアンカーボルト４の雄ネジ部５を貫通させるための細径の貫通孔３５が、前後に一対設けられている。また、これらの貫通孔３５の直上に位置する矩形部３２の上面３３には、上記雄ネジ部５にナット８を締結するための大径の通し孔３７がそれぞれ穿孔されている。図１に示すように、係る支持体３０の矩形部３２から立設する垂直片３８は、当該支持体３０の長手方向の両側が予め切除されており、露出した矩形部３２の上面３３に、一対の上記通し孔３７が開口している。また、図１，図３（Ａ）に示すように、垂直片３８には、建物の内外方向に沿って貫通する複数のピン孔３９が設けられている。
【００２１】
図３（Ｂ）に示すように、基礎１の上面２にスペーサ３を介して載置され且つその底片１４にアンカーボルト４を貫通させた土台本体１２の凹溝１３内に、支持体３０の矩形部３２を挿入して嵌合すると共に、左右のフランジ３６を各中空角形部１５の上面１７に載置させる。この際、各フランジ３６の先端は、土台本体１２の凸条１８，１９に接近または当接している。
係る状態で、通し孔３７からナット８と図示しないボックススパナ（ナット締め付け具）とを矩形部３２の中空部３２ａに挿入し、予め座金６を通した雄ネジ部５にナット８を締め付ける。この結果、図３（Ｂ）に示すように、支持体３０を土台本体１２と共に、スペーサ３を介して基礎１の上方に固定することができる。
尚、係る支持体３０の長手方向の両側には、図１に示すように、一対の前記カバー２０が同じ土台本体１２上に配置されている。また、土台本体１２に支持体３０を先に固定し、その後にカバー２０を取り付けるようにしても良い。更に、支持体３０が固定されない土台本体１２の位置では、その土台１０の上に施工される建築要素のサイズや形状によっては、カバー２０を省くことも可能である。
【００２２】
図１，４に示すように、土台本体１２と共にアンカーボルト４を介して基礎１の上方に固定される支持体３０の上には、角材からなる柱４０が立設される。係る柱４０は、その下端４２における内外方向の中央に、基礎１の長手方向に沿ったスリット４４が垂直に設けられている。係るスリット４４の幅と高さは、支持体３０の垂直片３８の厚みや高さとほぼ同じである。また、柱４０の下部には、上記スリット４４と中央で交差する複数の透孔４６が内外方向に沿って貫通している。係る柱４０は、図示しないクレーンなどにより上記支持体３０の上方に垂直に吊り下げられた後、図１，図４中の矢印で示すように、徐々に降下される。
【００２３】
すると、支持体３０の垂直片３８は、柱４０のスリット４４に挿入し、柱４０の下端（底面）４２は、支持体３０の矩形部３２の上面３３および各フランジ３６に接触し、係る状態で柱４０は支持体３０の上に支持される。同時に、柱４０の各透孔４６は、上記垂直片３８の各ピン孔３９と個別に連通する。
次いで、図１，図４に示すように、柱４０の各透孔４６およびこれに連通する垂直片３８の各ピン孔３９に、棒鋼などからなるピン（ドリフトピン）４８を図示しないハンマーにより個別に打ち込む。この結果、柱４０は、支持体３０上に抜け出し不能にして垂直に支持され且つ強固に固定される。尚、以上のピン孔３９、透孔４６、およびピン４８は、１個ずつまたは１本のみとしても良い。
【００２４】
以上のような建物用土台１０によれば、前記押出形材からなる長尺な土台本体１２を、基礎１の上面２に沿って固定し、その凹溝１３をカバー２０により必要に応じて覆うと共に、柱立設位置の直下では支持体３０を上記土台本体１２と共に基礎１に固定し且つその垂直片３８を柱４０のスリット４４に挿入して当該柱４０を垂直に支持することができる。更に、係る柱４０をピン４８により上記支持体３０から抜け出し不能にして固定することができる。しかも、土台本体１２、カバー２０、および支持体３０は、前記押出形材を切断し、孔明け加工や切り欠き加工するのみで用意できると共に、形状および寸法精度も高く、以降の建物の組み立て作業も容易となる。加えて、腐食や白蟻の食害からも保護される。従って、メンテナンスも不要で安定した土台となる。
【００２５】
図５（Ａ）は、前記のようにして立設される柱４０，４０間に位置する土台本体１２と、その凹溝１３に嵌合したカバー２０と、を示す。係る土台本体１２の底片１４のうち、図５（Ａ）で左側に位置する屋外側の中空角形部１５の底面には、その中空部１６の連通する長円形の通気孔１４ｃが複数穿孔される。また、通気孔１４ｃの真上に位置する中空角形部１５の上面１７にも、同様な通気孔１７ａが複数穿孔されている。これらの通気孔１４ｃ，１７ａは、予めプレス加工などにより形成される。尚、通気孔１４ｃ，１７ａは、複数の円形孔としても良い。
【００２６】
図５（Ｂ）は、前記のように立設された柱４０，４０間および前記スペーサ３，３間に位置する前記土台１０の土台本体１２およびカバー２０の断面を示す。図５（Ｂ）に示すように、土台本体１２およびカバー２０の上で且つ前記柱４０，４０間には、断熱材５６および合板５８が配置される。係る合板５８は、土台本体１２の凸条１９により位置決めされ、図示しない内装材の固定に活用される。また、上記断熱材５６の外側で且つ土台本体１２の屋外側に固定した合板５０との間には、通気路５７が位置している。尚、上記合板５０は、土台本体１２の底片１４から突出した凸条１４ｂにより、その下端が位置決めされている。
更に、上記合板５０の下端に沿って水切材５２の上端部５４が固定され、且つ係る水切材５２および合板５０の外側には、図示しない外装材が固定される。
【００２７】
図５（Ｂ）中の矢印で示すように、水切材５２と基礎１との隙間５５から上向きに進入した外気は、スペーサ３，３間から土台本体１２の通気孔１４ｃを通過し、中空部１６および上側の通気孔１７ａを経て、通気路５７内を上昇する。
この際、断熱材５６などに含まれている水分や湿気を除去したり、当該通気路５７内での結露を防ぐことができる。更に、通気路５７内に進入した外気が、図示しない建物の軒や棟付近に上昇するように循環させることにより、屋根裏や棟部での結露やすがもりを防止することが可能となる。
尚、土台本体１２の図５（Ｂ）において右側である屋内側に位置する中空角形部１５および凸条１４ａ，１９間には、図示しない根太受けが固定され、その上に根太および床材が配置される。
【００２８】
図６は、異なる形態の建物用土台６０に関する。係る土台６０は、図６（Ａ）に示す断面形状を有し且つ前記同様の押出形材からなる土台本体６２、支持体７８、および必要に応じて用いるカバー７０から構成される。
土台本体６２は、図６（Ａ）に示すように、下方の底片６４と、その両端から垂直に立設する縦片６３と、これらに囲まれ且つ上向きに開口した凹溝６５とから主要部を構成する断面チャンネル形を呈する。底片６４上で凹溝６５の底面には、左右一対ずつの凸条６４ｂとその間の凹部６６とが位置し、底片６４の屋内側には、凸条６４ａが水平に突出している。また、各縦片６３の内側の上部には、Ｌ形部６７と、その先端から水平に突出する固定片６８と、上向きに開口する細溝６９とが形成されている。更に、屋内側の縦片６３の上端には、その厚み分だけ屋内側にずれた凸条６３ａが立設している。係る土台本体６２は、以上の各部分を図６（Ａ）の奥行き方向（長手方向で且つ押出方向）の全長に沿って有する。
【００２９】
また、カバー７０は、図６（Ａ）に示すように、上方の水平片７２と、その中間から平行に垂下する一対の長縦片７４と、水平片７２の両端から短く垂下する一対の短縦片７５と、を図示の奥行き方向（長手方向で且つ押出方向）に沿って有する。水平片７２の屋内側には、凸条７３が水平に突出している。
更に、支持体７８は、図６（Ａ）に示すように、カバー７０と同じ水平片７２、一対の長縦片７４、一対の短縦片７５、および凸条７３を有し、更に一対の長縦片７４間に底面７４ａが配置され、且つ水平片７２の内外方向の中央から垂直片７６を一体に立設している。尚、図６（Ａ）において、底面７４ａと垂直片７６とは、カバー７０には不要なため、一点鎖線で表示した。
図６（Ａ）において、係る垂直片７６の奥行き（前後）方向に延びる水平片７２の中央には、ナット締め付け具挿入用の大径の通し孔７９が長縦片７４，７４間において前後に一対穿孔されている。また、底面７４ａの中央部には、アンカーボルト４が貫通する細径の貫通孔７４ｂが開設され、且つ底面７４ａの両端部には、小溝７４ｃが下向きに一対形成されている。尚、垂直片７６には、前記同様のピン孔（図示せず）が１個または複数個開設されている。
【００３０】
図６（Ｂ）に示すように、基礎１の上面２上に載置したスペーサ３，３上に、長尺な土台本体６２を載置し、スペーサ３および当該土台本体６２の底片６４を貫通するアンカーボルト４の雄ネジ部５に座金６を通してナット８を締め付ける。
次に、前記柱４０を立設しない位置における土台本体６２には、カバー７０を配置し、その短縦片７５，７５を当該土台本体６２の細溝６９，６９に嵌合し且つその長縦片７４，７４を上記土台本体６２の凹部６６，６６に嵌合する。この結果、土台本体６２の凹溝６５は、カバー７０の水平片７２により覆われ、係る水平片７２は、上記土台本体６２の固定片６８，６８上にも支持される。尚、水平片７２から延びた凸条７３は、土台本体６２の凸条６３ａの下部に当接する。
【００３１】
更に、前記柱４０の立設位置の直下における土台本体６２には、図６（Ｂ）に示すように、支持体７８を配置し、上記同様にその長縦片７４を凹部６６に嵌合し且つその短縦片７５を細溝６９に嵌合する。同時に、土台本体６２においてそれぞれ内側の各凸条６４ｂを、支持体７８の各小溝７４ｃに個別に嵌合する。
次いで、必要に応じて、支持体７８の水平片７２，７２から土台本体６２の固定片６８，６８に向けてネジ（ボルト）７１をネジ込んで、当該支持体７８を土台本体６２に固定する。この結果、図６（Ｂ）に示す建物用土台６０が形成される。
尚、上記支持体７８の直下に位置するアンカーボルト４は、前記実施形態と同様に固定される。即ち、基礎１との間にスペーサ３、土台本体６２、および支持体７８の貫通孔７４ｂを貫通するアンカーボルト４の雄ネジ部５に、通し孔７９から前記ナット締め付け工具を挿入してナット８を締結する。
【００３２】
そして、上記支持体７８の上方に前記柱４０を垂直に配置し、係る支持体７８の水平片７２にから立設する垂直片７６を、上記柱４０のスリット４４に挿入し且つ前記ピン４８を柱４０の透孔４６および垂直片７６のピン孔に貫通させる。以上のような建物用土台６０によっても、前記建物用土台１０と同様な効果を奏することが可能である。尚、カバー７０も前記ネジ７１で土台本体６２に固定しても良い。
【００３３】
図７乃至図９は、さらに異なる形態の建物用土台１００に関する。
建物用土台１００は、図７に示すように、基礎１の上面２に沿って配置され、基礎１中に埋設されたアンカーボルト４により固定されるものであり、基礎１の上面２に複数のスペーサ３を介して固定される長尺な土台本体１１０と、柱４０の立設位置のほぼ直下に位置し凹溝１１１を覆い且つ柱４０のスリット４４に挿入する垂直片１２１を立設している支持体１２０と、を備えて構成されている。
【００３４】
土台本体１１０は、図８（Ａ）に示すように、基礎１の上面２に載置したスペーサ３上に載置される底片１１２と、この底片１１２上の左右両側に形成された断面矩形の一対の中空角形部１１３，１１３と、これらを連結する上片１１４（図７参照）と、を備えて構成されている。また、土台本体１１０は、アルミニウム合金製の中空押出形材からなり、底片１１２，中空角形部１１３，１１３および上片１１４は一体に成形されている。なお、各中空角形部１１３の内部１１６（中空部１１６）は、断面ほぼ長方形を呈している。
【００３５】
凹溝１１１は、図８（Ａ）に示すように、一対の中空角形部１１３，１１３および底片１１２の間に位置しており、図９（Ａ）に示す押出形材１１０’の上面（上片１１４）の一部（符号１１４’を付した部位）を支持体１２０の長さ分だけ切除することにより形成される。
【００３６】
底片１１２には、図示は省略するが、アンカーボルト４を貫通させるための透孔が形成されている。また、図８（Ａ）に示すように、底片１１２の側端部１１２ａは、中空角形部１１３よりも外側に突出している。この底片１１２の側端部１１２ａには、図示は省略するが、大引などの横架材が載置される。
【００３７】
このような土台本体１１０によれば、図１に示すカバー２０を取り付ける必要がなくなるので、部品点数が少なくなり、設置作業の簡略化を図ることができる。
【００３８】
支持体１２０は、図７に示すように、土台本体１１０の凹溝１１１内に嵌合される矩形部１２２と、この矩形部１２２の上面１２２ａの長手方向中央部分に垂直に立設された垂直片１２１と、を備えて構成されている。言い換えれば、矩形部１２２の両端が、垂直片１２１の長手方向の両側に張り出しているといえる。支持体１２０は、アルミニウム合金製の押出形材を所定の長さで切断し且つ切欠き加工したものであり、垂直片１２１および矩形部１２２は、一体に成形されている。
【００３９】
垂直片１２１には、図７に示すように、建物の内外方向に貫通する複数のピン孔１２１ａが設けられている。ピン孔１２１ａは、柱４０に設けられた複数の透孔４６に対応する位置に形成されており、図示しないピンが挿通可能である。
【００４０】
矩形部１２２は、図８（Ｂ）に示すように、断面ほぼ長方形を呈している。また、矩形部１２２の高さ寸法は、この矩形部１２２を土台本体１１０の凹溝１１１内に嵌合したときに、その上面１２２ａが土台本体１１０の上面と面一になるように設定されている。また、図７に示すように、矩形部１２２の長さ寸法は、垂直片１２１の長さ寸法よりも大きい。すなわち、支持体１２０は、垂直片１２１とこの垂直片１２１の長手方向の両側に延長して形成される矩形部１２２とにより形成されているといえる。また、垂直片１２１の長手方向の両側に延長して形成された矩形部１２２には、その延長部（垂直片１２１の長手方向の縁端よりも張り出した部位）にアンカーボルト４を貫通させるための貫通孔１２２ｂが形成されている。
【００４１】
このような支持体１２０は、図９（Ｂ）に示すように、垂直片１２１となる部分（垂直片部分１２１’）と矩形部１２２となる部分（矩形部部分１２２’）とを有するアルミニウムまたはアルミニウム合金からなる押出形材１２０’、すなわち、垂直片１２１と矩形部１２２とを合わせた断面形状を有する押出形材１２０’を、その押出方向に沿って所定長さで切断すると共に、当該切断された押出形材１２０”において、その垂直片部分１２１”を、その中央部１２１Ａを残して適宜切除し、さらに、中央部１２１Ａに複数のピン孔１２１ａを穿設するとともに、矩形部１２２に貫通孔１２２ｂを穿設することで形成される。
【００４２】
このようにすると、溶接等により矩形部１２２と垂直片１２１とを一体にする場合に比べて、その寸法精度を格段に向上させることができるので、結果として歪の少ない建物を構築することが可能となる。なお、矩形部１２２を中空状としてもよい。
【００４３】
そして、図７に示すように、土台本体１１０の凹溝１１１に形成した透孔（図示せず）に基礎１の上面２から突出したアンカーボルト４を挿通させつつ、この土台本体１１０をスペーサ３上に載置し、さらに、支持体１２０の貫通孔１２２ｂにアンカーボルト４を挿通させつつ、この支持体１２０を凹溝１１１内に嵌合させ、支持体１２０の上面に突出したアンカーボルト４の雄ネジ部５に座金８を通し、ナット６で締結することにより、土台本体１１０および支持体１２０が同時に基礎１に固定される。なお、座金８の外法は、支持部１２０の矩形部１２２の幅寸法よりも大きい。
【００４４】
また、柱４０を建物用土台１００上に立設するには、支持体１２０の上方に柱４０を垂直に配置するとともに、その下端部に形成されたスリット４４を垂直片１２１に挿入し、さらに、図示しないピンを柱４０の透孔４６および垂直片１２１のピン孔１２１ａに貫通させればよい。
【００４５】
このような建物用土台１００によると、支持体１２０が土台本体１１０の凹溝１１１に嵌り込むため、その前後左右への移動・変形が抑制され、その結果、支持体１２０に固定される柱４０の接合強度が非常に高いものとなる。
【００４６】
また、図１０に示すように、建物の隅部においては、土台本体１１０の端部に凹溝１１５を設ける。この凹溝１１５は、図９（Ａ）に示す押出形材１１０’の上面（上片１１４）の端部（符号１１４”を付した部位）を支持体１３０の長さ分だけ切除することにより形成される。
【００４７】
支持体１３０は、図１０に示すように、土台本体１１０の凹溝１１５内に嵌合される矩形部１３２と、この矩形部１３２の上面１３２ａに垂直に立設された垂直片１３１と、を備えて構成されている。また、支持体１３０は、アルミニウム合金製の押出形材を所定の長さで切断し且つ切欠き加工したものであり、垂直片１３１および矩形部１３２は、一体に成形されているが、矩形部１３２のほうが垂直片１３１よりも長く、矩形部１３２の一端は垂直片１３１の長手方向に張り出している。
【００４８】
垂直片１３１には、建物の内外方向に貫通する複数のピン孔１３１ａが設けられている。ピン孔１３１ａは、隅柱４０’に設けられた複数の透孔４６に対応する位置に形成されており、図示しないピンが挿通可能である。
【００４９】
矩形部１３２は、その長さ寸法が垂直片１３１の長さ寸法よりも大きく、一方の縁端が垂直片１３１の縁端に揃えられており、他方の縁端は垂直片１３１の長手方向に張り出している。すなわち、支持体１３０は、垂直片１３１とこの垂直片１３１の長手方向の片側に延長して形成される矩形部１３２とにより形成されているといえる。その他の形態は、おおよそ図７に示す支持体１２０の矩形部１３２と同様であるので詳細な説明は省略するが、矩形部１３２は、断面ほぼ長方形を呈しており、また、矩形部１３２の高さ寸法は、この矩形部１３２を土台本体１１０の凹溝１１５内に嵌合したときに、その上面１３２ａが土台本体１１０の上面と面一になるように設定されている。また、図１０に示すように、垂直片１３１の長手方向の片側に延長して形成された矩形部１３２には、その延長部（垂直片１３１の長手方向の縁端よりも張り出した部位）にアンカーボルト４を貫通させるための貫通孔１３２ｂが形成されている。
【００５０】
また、支持体１３０は、図９（Ｂ）に示す支持体１２０と同様に、アルミニウムまたはアルミニウム合金からなる押出形材１２０’を、その押出方向に沿ってそれぞれの所定長さで切断すると共に、当該切断された押出形材（図示せず）のヒレ部を適宜切除することで形成される。
【００５１】
そして、図１０に示すように、土台本体１１０の凹溝１１５に形成した透孔（図示せず）にアンカーボルト４を挿通させつつ、この土台本体１１０をスペーサ３上に載置し、さらに、支持体１３０の貫通孔１３２ｂにアンカーボルト４を挿通させつつ、この支持体１３０を凹溝１１５内に嵌合させ、支持体１３０の上面に突出したアンカーボルト４の雄ネジ部５に座金８を通し、ナット６で締結することにより、土台本体１１０および支持体１３０が基礎１に同時に固定される。なお、図１１に示すように、座金８の外法は、支持部１３０の矩形部１３２の幅寸法よりも大きい。なお、図１１では、隅柱４０’および筋交１５０の図示を省略している。
【００５２】
また、隅柱４０’を建物用土台１００上に立設するには、支持体１３０の上方に隅柱４０’を垂直に配置するとともに、その下端部に形成されたスリット４４を垂直片１３１に挿入し、さらに、図示しないピンを隅柱４０’の透孔４６および垂直片１３１のピン孔１３１ａに貫通させればよい。
【００５３】
なお、本実施形態では、支持体１３０を隅柱４０’が立設される建物の隅部に使用した場合を例示したが、これに限定されることはなく、管柱や間柱等が立設される土台本体１１０の中間部に使用しても差し支えない。すなわち、土台本体１１０の中間部では、図７に示すように、矩形部１２２が垂直片１２１の長手方向の両側に張り出す支持体１２０を使用してもよいし、この支持体１２０に替えて、図１０に示す支持体１３０を土台本体１１０の中間部に使用しても差し支えない。どちらの形態の支持体を使用するかは、アンカーボルト４の配置等を勘案して決定すればよい。
【００５４】
また、土台本体１１０と隅柱４０’とで形成される枠体に筋交１５０（図１２（Ａ）（Ｂ）参照）を配設する場合には、図１０に示すように、土台本体１１０と直交する他の土台本体１１０上に筋交金物１４０を取り付け、この筋交金物１４０を利用して筋交１５０を取り付ければよい。
【００５５】
筋交金物１４０は、図１０に示すように、底板１４１と、この底板１４１の周縁に立設された側板１４２および背板１４３とから構成されており、底板１４１がドリルビス等の固着具により土台本体１１０の上面に固定され、側板１４２が固着具により隅柱４０’の側面に固定される。そして、筋交１５０の下端部が筋交金物１４０の背板１４３に固着具により固定される。
【００５６】
本発明は、以上において説明した各形態に限定されるものではない。
例えば、土台本体は比較的長尺であるが、基礎の上面で長手方向に沿って隣接する別の土台本体と連続して配置する場合、両者に跨り且つ両者の凹溝を覆うカバーまたは支持体を介して接続することも可能である。
また、土台本体は前記底片および凹溝を、支持体は上記凹溝を覆い且つ前記垂直片を、カバーは係る凹溝の開口部を覆う水平片を有していれば、これらの断面形状は、特に前記各形態に限定されず、任意の断面形状にすることができる。
更に、支持体の垂直片は、柱の固定に適していれば、当該支持体の内外方向における中央に限らず、任意の中間位置から立設しても良い。あるいは、押出方向に沿って長くした垂直片の中央部分を柱のスリットに挿入すると共に、当該垂直片のうち柱から外側に露出する部分に、例えば筋交いの下端部をボルトなどによって固定することも可能である。
尚、本発明の建物用土台は、その趣旨を逸脱しない範囲で、以上の他に種々変更することが可能である。

In general, as a building base fixed along the upper surface of a foundation made of concrete, a base made of wood having a square cross section is widely used in the conventional method and the prefabricated method. Such a base made of wood is fixed by anchor bolts projecting upward from the foundation, and pillars, studs and the like are also erected via the base (for example, see Patent Document 1).
[0003]
However, the conventional building base made of wood has the following problems.
(1) It is easily damaged by white ants and corroded by moisture.
(2) Repeating moisture absorption and release causes the cross-sectional dimensions of the foundation to change over time, causing distortion to the building.
(3) Since the weight is large, the workability on site is low and the cost is likely to be high.
(4) Since both the portion supporting the concentrated load, such as directly under the pillar, and the portion that is not so have the same cross section, the weight increases and the foundation material is wasted.
(5) Since the processing accuracy is low and the dimensions are likely to be distorted, it is difficult to make a modular unit and the workability of the building is lowered.
(6) It is necessary to process a joint structure that is complicated and requires skill at the joint portion with a pillar or the like.
(7) It tends to lead to environmental destruction by logging.
