【発明の属する技術分野】
本発明は、箱状の建物ユニットを複数備え、これら建物ユニットを補強する補強梁を備えたユニット式建物に関する。
【0002】
【背景技術】
従来より、工場で製造した箱状の建物ユニットを、建築現場で複数連結させて建築されるユニット式建物が利用されている。
このユニット式建物を形成する建物ユニットとしては、四隅の柱の上下端を天井梁および床梁で連結した箱状のフレームを有するものが一般的である。フレームには、天井梁に支持される天井面材、床梁に支持される床面材および部屋を仕切る間仕切壁等の内装材や、軽量気泡コンクリート等で形成された外壁等の外装材が工場で組付けられている。
【0003】
複数階を有するユニット式建物は、複数の建物ユニットで形成された下側建物ユニットと、これら下側建物ユニットの上に積層された上側建物ユニットとで構成される。この場合、一般に、上側建物ユニットとしては、下側建物ユニットと平面同一形状の建物ユニットが用いられる(例えば、特願2000−275032参照)。
このようにすれば、下側建物ユニットの柱の上に上側建物ユニットの柱が位置するから、上側建物ユニットの荷重が直接下側建物ユニットの柱ににかかることとなり、ユニット式建物の垂直荷重を安定して支持できる。
【0004】
【発明が解決しようとする課題】
ところで、顧客の希望によりユニット式建物の外観に特徴をもたせるため、また、顧客の希望する間取りを実現するため、上側建物ユニットの平面形状を下側建物ユニットの平面形状と異なるものとする場合がある。
この時、上側建物ユニットの4本の柱全てが下側建物ユニットの4本の柱の上に位置することはなく、上側建物ユニットの4本の柱のうち少なくとも1本は、下側建物ユニットの天井梁の中間に配置されることとなる。その結果、下側建物ユニットの天井梁が、ある一点で上側建物ユニットの柱の荷重を集中荷重として負担することになり、下側建物ユニットのフレームの強化が必要となって、ユニット式建物の建築コストが増大していた。
【0005】
本発明の目的は、上側建物ユニットの柱が下側建物ユニットの天井梁の中間に位置する場合であっても低コストで建築できるユニット式建物を提供することにある。
【0006】
【課題を解決するための手段】
上記目的を達成するため、本発明のユニット式建物は、次の構成を採用する。
本発明を図面を参照して説明すると、請求項1に記載のユニット式建物10は、四隅の柱41の上下端を天井梁42および床梁43で連結して箱状に形成されたフレーム40を有する建物ユニット20がその角隅部を寄せ合わせて複数配置された下側建物ユニット12Aと、これら下側建物ユニットの上に積層された上側建物ユニット12Bとを備え、これら上側建物ユニットの柱のうち少なくとも1つは、前記下側建物ユニットの天井梁の中間に位置する中間柱41Cとされたユニット式建物において、その中間に前記中間柱が位置する下側建物ユニットの天井梁42Cのうち少なくとも1つの両端に位置する柱間に架け渡される梁本体31と、この梁本体に設けられ前記中間柱を支持する支持部32とを有する補強梁30を備え、前記梁本体31は、その中間に前記中間柱41Cが位置する下側建物ユニットの天井梁42の外側面に配置され、前記支持部32は隣り合う上側建物ユニットの互いに近接する中間柱41Cを支持し、かつ、前記下側建物ユニットの柱41の間に設けられていることを特徴とする。
【0007】
この発明によれば、補強梁を設けたので、中間柱が負担する上側建物ユニットの垂直荷重は、補強梁の支持部、梁本体を介して、その中間に中間柱が位置する下側建物ユニットの天井梁の両端に位置する柱に伝達される。よって、中間柱の負担する垂直荷重が、その中間に中間柱が位置する下側建物ユニットの天井梁に過大な集中荷重として作用することがないから、下側建物ユニットのフレームを強化する必要がなく、ユニット式建物の建築コストを低減できる。
しかも、この発明によれば、梁本体を、その中間に中間柱が位置する下側建物ユニットの天井梁の側面に配置したので、下側建物ユニットの側面側から容易に補強梁の取付作業を行うことができる。
【0008】
請求項2に記載のユニット式建物は、請求項1に記載のユニット式建物において、前記支持部は、前記中間柱とその中間に前記中間柱が位置する下側建物ユニットの天井梁との間に介装される平板材であることを特徴とする。
この発明によれば、支持部を中間柱とその中間に中間柱が位置する下側建物ユニットの天井梁との間に介装される平板材としたので、例えば、緊締具等を介して中間柱の側面を支持する場合に比べ、中間柱の垂直荷重を確実に支持することができる。
【0010】
請求項3に記載のユニット式建物は、請求項1または2に記載のユニット式建物において、前記梁本体は、前記下側建物ユニットおよび前記上側建物ユニットに跨って配置されていることを特徴とする。
この発明によれば、梁本体を、下側建物ユニットおよび上側建物ユニットに跨って配置したので、梁本体の高さ寸法を大きく設定でき、補強梁の剛性を容易に向上できる。
【0011】
請求項4に記載のユニット式建物は、請求項1から3のいずれかに記載のユニット式建物において、前記中間柱に連結された床梁が交差する下側建物ユニットの天井梁のうち少なくとも1つの両端に位置する柱間に架け渡される梁本体と、この梁本体に設けられ前記上側建物ユニットの中間柱に連結された床梁を支持する支持部35とを有する第2の補強梁36を備えていることを特徴とする。
この発明によれば、中間柱に連結された床梁を支持する支持部を有する第2の補強梁を設けたので、中間柱に連結された床梁の長さが長い場合でも、この床梁が負担する垂直荷重を大幅に軽減できる。
【0012】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
図1には、本実施形態に係るユニット式建物10の全体斜視図が示されている。このユニット式建物10は、基礎11と、この基礎11の上に設けられた建物本体12と、この建物本体12の上に設けられた屋根13とを備えている。
このうち、建物本体12は、下側建物ユニットとしての1階建物ユニット12Aと、この1階建物ユニット12Aの上に積層された上側建物ユニットとしての2階建物ユニット12Bとを備え、これら各階建物ユニット12A、12Bは、複数の建物ユニット20がその角隅部を寄せ合わせて配置されて構成されている。
【0013】
図2には、建物ユニット20のフレーム40の全体斜視図が示されている。
建物ユニット20は、図2に示すように、四隅の柱41の上下端を連結する天井梁42および床梁43を有する箱状のフレーム40を備えている。このうち、柱41と天井梁42とは、柱41の柱頭側に配置される柱頭接合部材45を介して連結され、柱41と床梁43とは、柱41の柱脚側に配置される柱脚接合部材46を介して連結されている。
天井梁42としては、長さの異なる短辺天井梁42Aおよび長辺天井梁42Bの二種類が設けられ、床梁43としては、長さの異なる短辺床梁43Aおよび長辺床梁43Bの二種類が設けられている。また、対向する長辺天井梁42Bの間には、天井面材を支持するための天井小梁が架け渡され(図示省略)、また、対向する長辺床梁43Bの間には、床を形成するパーチクルボード等の床面材を支持するための複数の根太が架け渡されている(図示省略)。
【0014】
ここで、建物ユニット20は、その桁行方向の長さがその梁間方向の長さの2倍であって、その桁行方向に沿った平面20Aと、その梁間方向に沿った妻面20Bとを備えている。
【0015】
図3には、ユニット式建物10の1階天井梁伏図が示されている。
1階建物ユニット12Aは、その平面20Aで互いに隣接する2つの建物ユニット20(図3中下側に示す)と、これら建物ユニット20の妻面20Bに平面20Aで隣接する1つの建物ユニット20(図3中上側に示す)とを含んで構成されている。
2階建物ユニット12Bは、図示しないが、その平面20Aで互いに隣接する3つの建物ユニット20を含んで構成され、その桁行方向が図3中下側に位置する2つの1階建物ユニット12Aの桁行方向に直交するように、つまり、2つの1階建物ユニット12Aに跨るように積層されている。
【0016】
したがって、図3中下側に位置する2つの1階建物ユニット12Aの上に配置された2つの2階建物ユニット12Bのうち、互いに隣接する2本の柱41(図3中二点鎖線で示す)は、1階建物ユニット12Aの2本の長辺天井梁42Bの中間に位置している。
ここで、互いに隣接する2本の柱41を、中間柱41Cとし、この中間柱41Cがその中間に位置する1階建物ユニットの長辺天井梁42Bを、支持天井梁42Cとする。
【0017】
図4には、補強梁30の全体斜視図が示されている。
補強梁30は、平板材で長尺状に形成された梁本体31と、後述するシアプレート60と同様の平板材で形成され、梁本体31の1側面側でかつ長さ方向略中央に水平に設けられた支持部32とを備えている。
梁本体31の両端側には各々4つの挿通孔33が設けられ、その略中央には8つの挿通孔34が設けられている。
【0018】
図5には、ユニット式建物10の分解斜視図が示されている。図6および図7には、補強梁30両端および中央の断面図が示されている。
1階建物ユニット12Aと2階建物ユニット12Bとの連結には、平板状のシアプレート60が用いられる。シアプレート60が、1階建物ユニット12Aの隣接する複数の柱頭接合部材45と、これらの柱頭接合部材45の上に配置される2階建物ユニット12Bの柱脚接合部材46との間に介在されることにより、上下方向および水平方向に隣接する1階建物ユニット12Aおよび2階建物ユニット12B同士が連結される。
【0019】
補強梁30の梁本体31は、ユニット式建物10の支持天井梁42Cの側面であって支持天井梁42Cの両端の柱41間に架け渡されている。また、この支持天井梁42Cおよび2階建物ユニット12Bの短辺床梁43Aに跨って配置されている。
具体的には、梁本体31は、その両端に設けられた挿通孔34に緊締具81を挿通することによって、1階建物ユニット12Aの柱頭接合部材45および2階建物ユニット12Bの柱脚接合部材46に連結され、その略中央に設けられた挿通孔33に挿通された緊締具81によって、1階建物ユニット12Aの支持天井梁42Cおよび2階建物ユニット12Bの柱脚接合部材46に連結されている。
【0020】
補強梁30の支持部32は、2階建物ユニット12Bの中間柱41Cの下端にある柱脚接合部材46と1階建物ユニット12Aの支持天井梁42Cとの間に介装され、中間柱41Cの端部にある柱脚接合部材46を介して中間柱41Cを支持している。
【0021】
したがって、本実施形態によれば以下の効果がある。
(1)補強梁30を設けたので、中間柱41Cが負担する2階建物ユニット12Bの垂直荷重は、補強梁30の支持部32、梁本体31を介して、その中間に中間柱41Cが位置する1階建物ユニット12Aの支持天井梁42Cの両端に位置する柱41に伝達される。よって、中間柱41Cの負担する垂直荷重が、その中間に中間柱41Cが位置する1階建物ユニット12Aの支持天井梁42Cに過大な集中荷重として作用することがないから、1階建物ユニット12Aのフレーム40を強化する必要がなく、ユニット式建物10の建築コストを低減できる。
【0022】
(2)支持部32を2階建物ユニット12Bの中間柱41Cの下端にある柱脚接合部材46と1階建物ユニットの支持天井梁42Cとの間に介装される平板材としたので、例えば、緊締具等を介して柱脚接合部材46の側面を支持する場合に比べ、中間柱41Cの垂直荷重を確実に支持することができる。
【0023】
(3)梁本体31を、中間柱41Cがその中間に位置する1階建物ユニット12Aの支持天井梁42Cの側面に配置したので、1階建物ユニット12Aの側面側から容易に補強梁30の取付作業を行うことができる。
【0024】
(4)梁本体31を、1階建物ユニット12Aの支持天井梁42Cおよび2階建物ユニット12Bの短辺床梁43Aに跨って配置したので、梁本体31の高さ寸法を大きく設定でき、補強梁30の剛性を容易に向上できる。
【0025】
なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、本実施形態では、中間柱41Cがその中間に位置する2本の支持天井梁42Cを補強したが、これに限らず、図3に示すように、中間柱41Cに連結された長辺床梁43Bが交差する1階建物ユニット12Aの長辺天井梁42Bの両端に位置する柱間に架け渡される梁本体31と、中間柱41Cに連結された長辺床梁43Bを支持する支持部35とを有する第2の補強梁36を設けてもよい。
このようにしても、前記実施形態で述べた(1)〜(4)の効果に加え、以下の効果がある。
(5)中間柱41Cに連結された長辺床梁43Bを支持する支持部35を有する第2の補強梁36を設けたので、中間柱41Cに連結された長辺床梁43Bの長さが長い場合でも、この長辺床梁43Bが負担する垂直荷重を大幅に軽減できる。
【0026】
また、本実施形態では、2つの2階建物ユニット12Bを、互いに隣接する2つの1階建物ユニット12Aに跨るように積層したが、これに限らず、図8(A)に示すように、互いに隣接する3つの1階建物ユニット12Aに跨るように2階建物ユニット12Bを積層し、補強梁30,36で補強してもよい。なお、図8(A)において、2階建物ユニット12Bは、二点鎖線で示されている。
