Description

【０００１】
【発明の属する技術分野】
本発明は屋外空間支持梁を備えたバルコニー、２階の玄関ポーチ、外廊下等の屋外空間を建物に接続した屋外空間の接続構造に関する。
【０００２】
【従来の技術】
従来、片持式のバルコニー支持梁を備えたバルコニー等の屋外空間を建物に取り付けた屋外空間の接続構造としては種々知られている。
例えば、特開平７−２５９１７８号公報（従来例１と称する）に記載されているように、建物本体に補助梁を外壁にほぼ直交した状態に設け、この外壁に取り付けられるバルコニーには、突出方向に向けてバルコニー支持梁を設け、この補助梁とバルコニー支持梁とを、外壁近傍に設けられている構造材を挟んで、ほぼ同一直線上に連結したバルコニーの接続構造が知られている。
【０００３】
この従来例１記載のように、バルコニー支持梁と補助梁とがほぼ同一直線上に連結されていると、外壁近傍の構造材を挟んでバルコニー支持梁と補助梁とがほぼ同一直線上に連結されて、あたかも１本の梁が設けられたと同じようになり、その結果、外壁近傍の構造材に作用する曲げモーメントが減少するという特徴があり、バルコニー支持梁が片持式の梁であっても、このバルコニー支持梁でバルコニーの荷重を支えることができ、好ましい構造である。
【０００４】
又、特許第２６１０７５５号（従来例２と称する）には、内部に少なくとも前側が開放されたバルコニー部と、このバルコニー部から区画された居室部とからなる建物ユニットと、バルコニーユニットとからなり、この建物ユニットのバルコニー部の屋外側にバルコニーユニットを取り付けて、このバルコニーユニットの床と建物ユニットのバルコニー部の床とを連結して拡大空間の床を形成したバルコニー付き建物が記載されている。
【０００５】
そして、このバルコニーユニットは、建物ユニットに接続された接続構造は明らかでないが、明細書に添付の図には、屋外側に柱がないことから判断して、片持ちバルコニーであると思われる。そして、この片持ちバルコニーが建物ユニットの屋外側に突出して取り付けられている実施例が記載されている。
このバルコニー付き建物では、バルコニーの床と建物ユニットのバルコニー部とが連結された拡大空間が形成されているので、バルコニーを広く使用することができ、好ましい構造である。
【０００６】
【発明が解決しようとする課題】
従来例２記載のバルコニー付き建物のような通常の片持式のバルコニーでは、特開平６−４９８９２号公報に記載あるように、バルコニーに屋外方向に突出するバルコニー床梁（公報では腕木と記載されている）を設け、このバルコニー床梁と建物の床梁等の構造材とをボルト・ナット等の接続具で接続した構造をしている。
【０００７】
しかし、かかる接続構造では、バルコニーが屋外側に長く突出したり、バルコニーが重い場合には、建物ユニットのバルコニーに接続される床梁等の構造材に過大な剪断曲げモーメントが作用し、床梁等の構造材が捩じれて、バルコニーの屋外側が垂れ下がったり、最悪の場合には、バルコニーが落下するという問題が発生する。従って、この従来例２記載のバルコニー付き建物は短く突出したバルコニーにしか適用できないという問題がある。
【０００８】
又、従来例１記載のバルコニーの接続構造では、バルコニー支持梁とほぼ同一直線上に連結されている補助梁がバルコニーを支持しているので、このバルコニー支持梁と補助梁とがあたかも１本の梁のようになり、上記のような問題がないが、建物本体にバルコニー支持梁とほぼ同じ数だけ補助梁を設ける必要があり、建物が高価になるという問題がある。
【０００９】
そこで、本発明の目的は、ある程度長く突出したり重い屋外空間でも設けることができ、しかも、建物本体や建物ユニットの補助梁の数を少なくすることのできる屋外空間の接続構造を提供することである。
【００１０】
【課題を解決するための手段】
本発明は上記目的を達成するためになしたものであって、請求項１記載の発明は、屋外側の２本の柱、前記２本の柱の下部間を連結する第一構造材、前記第一構造材の屋外側に位置して前記２本の柱間に設けられた外壁、前記第一構造材に直交し且つ前記柱の下端部に連結された第二構造材、前記第一，第二構造材とは別に内部に設けられた第三構造材、及び、前記別の第二構造材または前記第一構造材にほぼ直交し且つ屋外側が第一構造材に連結され且つ屋内側が前記第三構造材に連結された補助梁を備える建物本体と、前記建物本体の外側に突出して設けられ且つ屋内側が前記建物本体に連結される複数本の屋外空間支持梁を有する屋外側空間と、を備えると共に、前記複数の屋外空間支持梁の一つと前記第二構造材とが前記柱を介してほぼ同一直線上に連結され、前記複数の屋外空間支持梁のうちの他のものと前記補助梁がほぼ同一直線上に連結されている屋外空間の接続構造であって、前記屋外空間支持梁の一つの屋内側端面に設けられた第１の接続板と、前記第二構造材の前記柱側の端部に設けられた第２の接続板と、を備えると共に、前記第１，第２の接続板と前記柱がこれらを貫通するボルトを介して連結されている屋外空間の接続構造としたことを特徴とする。
【００１１】
請求項２記載の発明は、請求項１に記載の屋外空間の接続構造において、前記複数の屋外空間支持梁のうちの他のものと前記補助梁が前記第一の構造材を介してほぼ同一直線上に連結されていると共に、前記複数の屋外空間支持梁のうちの他のものの屋内側端面に第３の接続板が設けられ、前記補助梁の前記第二構造材側の端部に第４の接続板が設けられ、前記第３，第４の接続板と前記第一構造材がこれらを貫通するボルトで連結されている屋外空間の接続構造としたことを特徴とする。
【００１２】
請求項３記載の発明は、請求項１または２記載の発明に係り、前記屋外空間の２個以上が一定の距離を隔てて設けられ、この２個以上の屋外空間の床が連結床パネルで連結されているものである。
【００１３】
請求項４記載の発明は、請求項１〜３のいずれかに記載の発明に係り、前記屋外空間に隣接する建物本体または建物ユニットの中に接続空間部が設けられ、この接続空間部の床と屋外空間の床とで連続した拡大空間の床が形成されているものである。
【００１４】
請求項５記載の発明は、請求項１〜４のいずれかに記載の発明に係り、前記補助梁が構造材または床梁とほぼ同じ断面形状を有するものである。
本発明における屋外空間とは、建物本体または建物ユニットの外壁から屋外方向に突出して設けられた空間のことであって、建物本体または建物ユニットの外壁から突出しているバルコニー、２階の玄関ポーチ、階段の踊り場、外廊下、押入れ、居室の一部等をいう。
【００１５】
本発明においては、屋外空間支持梁と、構造材や床梁とがほぼ同一直線上に連結されているが、このほぼ同一直線上とは、実質的に同一直線上になっていればよく、若干段差がある状態に連結されていてもよい。即ち、屋外空間支持梁に作用する曲げモーメントのほとんどが構造材や床梁に伝わる状態になっていればよい。
【００１６】
請求項１記載の発明においては屋外空間支持梁と第二構造材とがほぼ同一直線上に連結されている。かかる構造にするためには、屋外空間支持梁を接続する部分に第二構造材の端面が顕れていれば、屋外空間支持梁の端面と直接第二構造材の端面とを直接連結して、屋外空間支持梁と第二構造材とをほぼ一直線上に連結すればよいし、屋外空間支持梁の端面と第二構造材の端面との間に第一構造材や柱や柱を取り付ける柱取付筒等の柱取付部材等が有る場合には、この第一構造材や柱や柱取付部材等を挟んで、屋外空間支持梁と第二構造材とをほぼ同一直線上に連結すればよい。
【００１７】
請求項２記載の発明における床梁とは、床に設けられた構造材をいい、建物ユニットの周囲に設けられた床梁は勿論のこと、この床梁に差し渡された床小梁といわれる床梁も含むものである。
【００１８】
（作用）
請求項１記載の発明では、屋外空間には、突出方向に向けて複数本の屋外空間支持梁が設けられ、この中の１本の屋外空間支持梁と第二構造材とがほぼ同一直線上に連結され、その他の屋外空間支持梁と、別の第二構造材または、第一構造材にほぼ直交し、屋外側が第一構造材に屋内側が内部の第三構造材に連結された補助梁とがほぼ同一直線上に連結されているので、ほぼ同一直線上に連結されている屋外空間支持梁と第二構造材や別の第二構造材や補助梁とが、あたかも１本の梁のようになる。
【００１９】
従って、屋外空間支持梁が片持式の梁であっても、この複数本の屋外空間支持梁で屋外空間の荷重を支えることができ、この請求項１記載の屋外空間の接続構造を、屋外空間が屋外方向にある程度長く突出している屋外空間や、ある程度重い屋外空間に適用しても支障がない。
又、この屋外空間の接続構造では、屋外空間支持梁が建物本体に備えられている第二構造材や別の第二構造材に連結されているので、屋外空間が第二構造材や別の第二構造材に連結されているだけ、この屋外空間に連結する補助梁を減らすことができる。従って、建物がそれだけ安価になる。
【００２０】
請求項２記載の発明では、屋外空間には、突出方向に向けて複数本の屋外空間支持梁が設けられ、この中の１本の屋外空間支持梁と第一床梁にほぼ直交している第二床梁とが、柱を挟んでほぼ同一直線上に連結され、その他の屋外空間支持梁と、第一床梁にほぼ直交している別の第二床梁、または第一床梁にほぼ直交し、屋外側が第一床梁に屋内側が第一床梁の対辺にある第三床梁に接続された補助梁とが、柱または第一床梁を挟んでほぼ同一直線上に連結されているので、柱を挟んでほぼ同一直線上に連結されている屋外空間支持梁と第二床梁とが、又、柱または第一床梁を挟んでほぼ同一直線上に連結されている屋外空間支持梁と別の第二床梁や補助梁とが、あたかも１本の梁のようになる。
【００２１】
従って、床梁や柱に作用する曲げモーメントが減少し、屋外空間支持梁が片持式の梁であっても、この複数本の屋外空間支持梁で屋外空間の荷重を支えることができ、この請求項２記載の屋外空間の接続構造を、屋外空間が屋外方向にある程度長く突出している屋外空間や、ある程度重い屋外空間に適用しても支障がない。
又、この屋外空間の接続構造では、屋外空間支持梁が建物ユニットに備えられている第二床梁や別の第二床梁に連結されているので、屋外空間支持梁が第二床梁や別の第二床梁に連結されているだけ、この屋外空間支持梁に接続する補助梁を減らすことができる。従って、建物ユニットがそれだけ安価になる。
【００２２】
請求項３記載の発明では、屋外空間の２個以上が一定の距離を隔てて設けられ、この２個以上の屋外空間の床が連結床パネルで連結されているので、屋外空間が連結床パネルの面積だけ広くなるし、この連結床パネルの上を通って一方の屋外空間から他方の屋外空間に行けるようになり、極めて便利である。
【００２３】
請求項４記載の発明では、屋外空間に隣接する建物本体または建物ユニットの中に接続空間部が設けられ、この接続空間部の床と屋外空間の床とで連続した拡大空間の床が形成されているので、この形成された屋外空間と接続空間部とからなる拡大空間は広く、使用し易い。
【００２４】
請求項５記載の発明では、補助梁が構造材または床梁とほぼ同じ断面形状を有するので、補助梁が構造材や床梁とほぼ同じ程度の機械的強度を有するようになり、この補助梁に接続された屋外空間支持梁の曲げモーメントに対する抵抗性が構造材や床梁と同じ程度に大きいし、補助梁と構造材の形状が同じで両者を接続し易い。
【００２５】
【発明の実施の形態】
次に、本発明の実施の形態を実施例で説明する。
（実施例１）
図１〜図７は本発明をユニット建物に採用した一実施例を示すもので、図１はユニット建物を示す斜視図、図２は建物ユニットを示す一部切欠斜視図、図３はバルコニー取付可能な建物ユニットを示す一部切欠斜視図、図４はバルコニー取付可能な建物ユニットの床梁と柱の接続部分を示す斜視図、図５はバルコニーを示す一部切欠斜視図、図６はユニット建物にの主要部を構造材のみで示す平面図、図７は図６のＡ−Ａ線における断面図である。
【００２６】
Ｕはユニット建物であり、このユニット建物Ｕは、図１に示すように、基礎９９の上に９個の建物ユニット１が据え付けられて１階が形成され、この１階の建物ユニット１の上に８個の建物ユニット１と１個のバルコニー取付可能な建物ユニット２が据え付けられ、このバルコニー取付可能な建物ユニット２にバルコニー４が接続されて２階が形成され、この２階の建物ユニット１とバルコニー取付可能な建物ユニット２の上に屋根パネル３が取り付けられたものである。
【００２７】
このとき使用される建物ユニット１は、図２に示すように、矩形の四隅に立設された４本の鋼製の四角筒体の柱１１と、この４本の柱１１の下端部を矩形の辺に沿って連結された４本の鋼製の断面コ字形長尺体の床梁１２とからなる骨格を備えている。
【００２８】
そして、建物ユニット１は、この骨格の相対する長辺の床梁１２の上に複数本の鋼製の断面ハット形の床根太１５が差し渡されて取り付けられ、この床根太１５の上にパーチクルボードの床材１６が取り付けられて床が形成され、４本の柱１１の上端部に天井パネル１７が取り付けられて天井が形成されたものである。尚、図１に示すように、外壁９を設ける場所には、隣接する２本の柱１１の間に図示しない外壁パネルが取り付けられて床梁１２の屋外側に外壁９が形成されている。
【００２９】
バルコニー取付可能な建物ユニット２は上記建物ユニット１とほぼ同じ構造を備えているが、図４に示すように、床梁２２に接続板２８が取り付けられていて、この床梁２２が柱２１に接続板２８を介して取り付けられていることが異なる。尚、このバルコニー取付可能な建物ユニット２の外壁９には、図１に示すように、開口部９５が設けられ、この開口部９５には窓９６が取り付けられ、その屋外側にバルコニー４が接続されている。
【００３０】
即ち、バルコニー取付可能な建物ユニット２は、図３に示すように、矩形の四隅に立設された４本の鋼製の四角筒体の柱２１と、この４本の柱２１の下端部を矩形の辺に沿って連結された４本の鋼製の断面コ字形長尺体の床梁２２とからなる骨格を備えている。
【００３１】
そして、建物ユニット２は、この骨格の相対する長辺の床梁２２の上に複数本の鋼製の断面ハット形長尺体の床根太２５が差し渡されて取り付けられ、この床根太２５の上にパーチクルボードの床材２６が取り付けられて床が形成され、４本の柱２１の上端部に天井パネル２７が取り付けられて天井が形成されたものである。尚、外壁９を設ける場所には、図１に示すように、隣接する２本の柱２１の間に図示しない外壁パネルが取り付けられて床梁２２の屋外側に外壁９が形成され、この外壁９に開口部９５が設けられ、この開口部９５に窓９６が設けられている。
【００３２】
バルコニー４は、図５に示すように、２本のバルコニー支持梁４１と、この２本のバルコニー支持梁４１の屋内側端部を連結する屋内側梁４２と、２本のバルコニー支持梁４１の屋外側端部を連結する軒先梁４３とからなる骨格を備えている。
尚、このバルコニー支持梁４１の屋内側端面には、接続板４８が取り付けられている。
【００３３】
そして、このバルコニー４は、屋内側梁４２と軒先梁４３の上に木製の床根太４６が架け渡されて取り付けられ、この床根太４６の上にバルコニー床材４７が設けられてバルコニー床が形成され、バルコニー支持梁４１と軒先梁４３の上に手摺り４９がコ字形に立設されたものである。
このバルコニー４は、図６、図７に示すように、バルコニー支持梁４１の屋内側端面に取り付けられている接続板４８と短辺の床梁２２の接続板２８とが柱２１を挟んで対峙するように、バルコニー支持梁４１が配置され、短辺の床梁２２の接続板２８から柱２１を経てバルコニー支持梁４１の接続板４８に貫通されたボルト８とこのボルト８に螺合されたナット８１でバルコニー取付可能な建物ユニット２に取り付けられている。
【００３４】
次に、このユニット建物Ｕの施工方法について説明する。
図２に示すように、工場で、矩形の四隅に４本の柱１１を立設し、この４本の柱１１の下端部を４本の床梁１２で連結して、建物ユニット１の骨格を製造する。
そして、この建物ユニット１の骨格の対向する長辺の床梁１２、１２に複数本の床根太１５を架け渡して取り付け、この床根太１５の上に床材１６を取り付けて床を形成し、４本の柱１１の上端部に天井パネル１７を取り付けて天井を形成し、外壁９を設ける場所には、柱１１の間に外壁パネルを取り付けて外壁９を床梁１２の屋外側に形成し、種々な仕上げを行って建物ユニット１を製造する。
【００３５】
又、同様にして、バルコニー取付可能な建物ユニット２を製造する。但し、この際、床梁２２には、接続板２８を取り付けていて、床梁２２を柱２１に接続板２８を介して取り付け、バルコニー４に面する外壁９に開口部９５を設け、この開口部９５に窓９６を取り付ける。
又、図５に示すように、２本のバルコニー支持梁４１の屋内側端部を屋内側梁４２で連結し、２本のバルコニー支持梁４１の屋外側端部を軒先梁４３で連結してバルコニー４の骨格を製造する。
【００３６】
このバルコニー支持梁４１の屋内側端面に接続板４８を取り付ける。
そして、屋内側梁４２と軒先梁４３の上に床根太４６を架け渡して取り付け、この床根太４６の上にバルコニー床材４７を設けてバルコニー床を形成し、バルコニー支持梁４１と軒先梁４３の上に手摺り４９を立設してバルコニー４を製造する。
このようにして製造した建物ユニット１、バルコニー取付可能な建物ユニット２、屋根パネル３、バルコニー４等を施工現場に運搬する。
【００３７】
施工現場では、予め設けられている基礎９９の上に９個の建物ユニット１を据え付けて１階を形成し、この１階の建物ユニット１の上に８個の建物ユニット１と１個のバルコニー取付可能な建物ユニット２を据え付け、このバルコニー取付可能な建物ユニット２にバルコニー４を接続して２階を形成し、この２階の建物ユニット１とバルコニー取付可能な建物ユニット２の上に屋根パネル３を取り付け、種々な仕上げを行うとユニット建物Ｕが完成する。
【００３８】
この際のバルコニー４の接続方法を説明する。
図６、図７に示すように、バルコニー支持梁４１の屋内側端面に取り付けられている接続板４８をバルコニー取付可能な建物ユニット２の柱２１の下端部に沿わせ、短辺の床梁２２の接続板２８から柱２１を経てバルコニー支持梁４１の接続板４８にボルト８を貫通させ、このボルト８にナット８１を螺着させて、バルコニー４をバルコニー取付可能な建物ユニット２に取り付ける。
このようにして、２本のバルコニー支持梁４１を建物ユニット２の柱２１にそれぞれ別々に取り付ける。
【００３９】
すると、この２本のバルコニー支持梁４１と２本の短辺の床梁２２とが柱２１を挟んでほぼ一直線上に連結される。
このようにして完成したユニット建物Ｕでは、バルコニー４には、突出方向に向けて２本のバルコニー支持梁４１が設けられ、この２本のバルコニー支持梁４１と外壁９近傍の長辺の床梁２２にほぼ直交している２本の短辺の床梁２２とが、図７に示すように、柱２１を挟んでほぼ同一直線上に連結されているから、この柱２１を挟んでほぼ同一直線上に連結されているバルコニー支持梁４１と短辺の床梁２２が、あたかも１本の梁のようになる。
【００４０】
従って、柱２１に作用する曲げモーメントが減少し、バルコニー支持梁４１が片持式の梁であっても、この２本のバルコニー支持梁４１でバルコニー４の荷重を支えることができ、バルコニー４が屋外方向にある程度長く突出していたり、ある程度重いものでも支障がない。
【００４１】
又、このバルコニー４の接続構造では、バルコニー支持梁４１が短辺の床梁２２に連結され、補助梁がないので、従来の補助梁を備えたバルコニー取付可能な建物ユニットより安価になる。又、建物ユニット１の床梁１２を、接続板２８を設けた床梁２２に替えるだけで、建物ユニット１とほぼ同じ構造の骨格をバルコニー取付可能な建物ユニット２の骨格に使用することができ、更に安価になる。
【００４２】
（実施例２）
図８〜図１０は本発明の他の実施例を示すもので、図８はユニット建物の主要部を示す斜視図、図９はユニット建物の主要部を構造材のみで示す平面図、図１０は図９のＢ−Ｂ線における断面図である。
【００４３】
この図８〜図１０に示す実施例２のユニット建物Ｕａを図１〜図７に示す実施例１に示すユニット建物と比較すると、バルコニー取付可能な建物ユニット２ａの構造が異なる。
即ち、図９に示すように、矩形の四隅に立設された４本の柱２１ａと、この矩形の四隅に立設された４本の柱２１ａの下端部を矩形の辺に沿って連結された４本の鋼製の断面コ字形長尺体の床梁２２ａと、短辺の床梁２２ａの中間部を長辺の床梁２２ａにほぼ平行に結ぶ床小梁２３ａと、この床小梁２３ａの中間部に立設された間柱２４ａと、長辺の床梁２２ａと短辺の床梁２２ａの上に立設された間柱２４ａからなる骨格を備えている。
【００４４】
尚、この建物ユニット２ａの床梁２２ａと柱２１ａとの接続は、図１０に示すように、接続板２８ａを介して行われている。
そして、建物ユニット２ａは、この骨格の相対する長辺の床梁２２ａの上に複数本の床根太１５ａが差し渡されて取り付けられ、この床根太１５ａの上に床材１６ａが取り付けられて床が形成され、矩形の四隅に立設された４本の柱２１ａの上端部に天井パネルが取り付けられて天井が形成され、端側の短辺の床梁２２ａの外側に外壁９ａが設けられ、床小梁２３ａの上の間柱２４ａ間に正面外壁９１ａが立設され、この正面外壁９１ａの端部から長辺の床梁２２ａの上の間柱２４ａまでに袖壁９２ａが立設され、この間柱２４ａから隣接する建物ユニット１ａまでに壁９ａが立設されたものである。
【００４５】
そして、この正面外壁９１ａには開口９５ａが設けられ、この開口９５ａに窓９６ａが取り付けられ、このコ字形の正面外壁９１ａと袖壁９２ａとで囲まれた部分に屋外方向が開口された接続空間部Ｓａが形成されている。尚、このバルコニー４ａの床材４７ａと接続空間部Ｓａの床材１６ａとは、図１０に示すように、ほぼ同じ高さになっていて、連続した床を形成している。
その他の構造は実施例１とほぼ同じであるので、説明を省略する。
【００４６】
次に、このユニット建物Ｕａの施工方法について説明する。
ユニット建物Ｕａの施工方法は実施例１とほぼ同じように、工場で、建物ユニット１ａ、バルコニー取付可能な建物ユニット２ａ、バルコニー４ａ、屋根パネル３ａ等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ａ、バルコニー取付可能な建物ユニット２ａを据え付け、バルコニー取付可能な建物ユニット２ａにバルコニー４ａを接続し、屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕａが完成する。
【００４７】
この際のバルコニー取付可能な建物ユニット２ａにバルコニー４ａを接続するバルコニー４ａの接続方法および作用について説明する。
バルコニー４ａを、実施例１と同様に、バルコニー支持梁４１ａの屋内側端面に取り付けられている接続板４８ａと短辺の床梁２２ａの接続板２８ａとを柱２１ａを挟んで対峙させ、短辺の床梁２２ａの接続板２８ａから柱２１ａを経てバルコニー支持梁４１ａの接続板４８ａにボルト８ａを貫通させ、このボルト８ａにナット８１ａを螺合させて、バルコニー取付可能な建物ユニット２ａに取り付ける。
【００４８】
すると、図１０に示すように、２本のバルコニー支持梁４１ａと２本の短辺の床梁２２ａとが柱２１ａを挟んでほぼ一直線上に連結されるし、バルコニー４ａの床材４７ａ（バルコニー４ａの床）と、このバルコニー４ａに続くバルコニー取付可能な建物ユニット２ａの床材１６ａ（接続空間部Ｓａの床）とが連結されて、このバルコニー４ａと接続空間部Ｓａとが連続した拡大空間が形成される。
【００４９】
このようにして完成したユニット建物Ｕａでは、バルコニー４ａには、突出方向に向けて２本のバルコニー支持梁４１ａが設けられ、この２本のバルコニー支持梁４１ａとバルコニー取付可能な建物ユニット２ａの短辺の床梁２２ａとが、図１０に示すように、柱２１ａを挟んでほぼ同一直線上に連結されているから、この柱２１ａを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ａと短辺の床梁２２ａが、あたかも１本の梁のようになる。
従って、柱２１ａに作用する曲げモーメントが減少し、バルコニー支持梁４１ａが片持式の梁であっても、この２本のバルコニー支持梁４１ａでバルコニー４ａの荷重を支えることができ、バルコニー４ａが屋外方向にある程度長く突出したり、ある程度重いバルコニーでも支障がない。
【００５０】
又、このバルコニー４ａの接続構造では、補助梁がないので、従来の補助梁を備えたバルコニー取付可能な建物ユニットより安価になる。又、建物ユニット１ａの床梁を、接続板２８ａを設けた床梁２２ａに替えるだけで、建物ユニット１ａとほぼ同じ構造の骨格をバルコニー取付可能な建物ユニット２ａの骨格に使用することができ、更に、安価になる。
更に、上記効果に加えて、コ字形の正面外壁９１ａと袖壁９２ａで区切られた部分にバルコニーに続く接続空間部Ｓａが形成され、この接続空間部Ｓａと、バルコニー４ａの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。
【００５１】
（実施例３）
図１１〜図１４は本発明の別の実施例を示すもので、図１１はユニット建物の主要部を示す斜視図、図１２はユニット建物の主要部を構造材のみで示す平面図、図１３（イ）はバルコニーＡを示す一部切欠斜視図、（ロ）はバルコニーＢを示す一部切欠斜視図である。
【００５２】
この図１１〜図１３に示す実施例３を図１〜図７に示す実施例１と比較すると、図１１に示すように、バルコニー４ｂがバルコニーＡ４ｂ−１とバルコニーＢ４ｂ−２の２種類あることと、バルコニー取付可能な建物ユニット２ｂの構造とが異なる。
即ち、図１２に示すように、矩形の四隅に立設された４本の柱２１ｂとこの矩形の四隅に立設された４本の柱２１ｂの下端部を矩形の辺に沿って連結された４本の鋼製の断面コ字形長尺体の床梁２２ｂと、相対する短辺の床梁２２ｂの中間部に立設された間柱２４ｂと、相対する短辺の床梁２２ｂの中間部を結ぶ床小梁２３ｂとからなる骨格を備えている。
【００５３】
尚、この建物ユニット２ｂの床梁２２ｂと柱２１ｂとの接続は、接続板を介して行われる。
そして、建物ユニット２ｂは、この骨格の相対する長辺の床梁２２ａの上に複数本の床根太が差し渡されて取り付けられ、この床根太の上に床材が取り付けられて床が形成され、矩形の四隅に立設された４本の柱２１ｂの上端部に天井パネルが取り付けられて天井が形成され、端側の短辺の床梁２２ｂの上に間柱２４ａまでの外壁９ｂが設けられ、床小梁２３ｂの上に正面外壁９１ｂが設けられ、この正面外壁９１ｂの端部から隣接する建物ユニット１ａとの境界に沿って袖壁９２ｂが設けられている。

そして、この正面外壁９１ｂには開口９５ｂが設けられ、この開口９５ｂに窓９６ｂが取り付けられ、このコ字形の正面外壁９１ｂと袖壁９２ｂとで囲まれた部分に屋外方向が開口された接続空間部Ｓｂが形成されている。尚、このバルコニー４ａの床材と接続空間部Ｓｂの床材とは、ほぼ同じ高さになっていて、連続した床を形成している。
又、バルコニーＡ４ｂ−１は、図１３（イ）に示すように、２本のバルコニー支持梁４１ｂと、この２本の支持梁４１ｂの屋内側端部を連結する屋内側梁４２ｂと、２本のバルコニー支持梁４１ｂの屋外側端部を連結する軒先梁４３ｂとからなる骨格を備えている。
【００５５】
尚、このバルコニー支持梁４１ｂの屋内側端面には接続板４８ｂが取り付けられている。
そして、このバルコニーＡ４ｂ−１は、屋内側梁４２ｂと軒先梁４３ｂの上に床根太４６ｂが架け渡されて取り付けられ、この床根太４６ｂの上にバルコニー床材４７ｂが設けられて床が形成され、端側のバルコニー支持梁４１ｂと軒先梁４３ｂの上にＬ字形に手摺り４９ｂが立設されたものである。
【００５６】
又、バルコニーＢ４ｂ−２は、図１３（ロ）に示すように、２本のバルコニー支持梁４１ｂと、この２本の支持梁４１ｂの屋内側端部を連結する屋内側梁４２ｂと、２本のバルコニー支持梁４１ｂの屋外側端部を連結する軒先梁４３ｂと、屋内側梁４２ｂが延長された延長屋内側梁４４ａと、軒先梁４３ｂが延長された延長軒先梁４５ｂと、この延長屋内側梁４４ｂの先端と延長軒先梁４５ｂの先端を結ぶ連結梁４０ｂとからなる骨格を備えている。
【００５７】
尚、このバルコニー支持梁４１ｂの屋内側端面には接続板４８ｂが取り付けられている。
そして、このバルコニーＢ４ｂ−２は、屋内側梁４２ｂや延長屋内側梁４４ｂと軒先梁４３ｂや延長軒先梁４５ｂの上に床根太４６ｂが架け渡されて取り付けられ、この床根太４６ｂの上にバルコニー床材４７ｂが設けられて床が形成され、端側のバルコニー支持梁４１ｂと軒先梁４３ｂと延長軒先梁４５ｂと連結梁４０ｂの上にコ字形に手摺り４９ｂが立設されたものである。
その他の構造は実施例１とほぼ同じであるので、説明を省略する。
【００５８】
次に、このユニット建物Ｕｂの施工方法について説明する。
このユニット建物Ｕｂの施工方法は実施例１とほぼ同じように、工場で、建物ユニット、バルコニー取付可能な建物ユニット２ｂ、バルコニーＡ４ｂ−１、バルコニーＢ４ｂ−２、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット、バルコニー取付可能な建物ユニット２ｂを据え付け、このバルコニー取付可能な建物ユニット２ｂにバルコニーＡ４ｂ−１、バルコニーＢ４ｂ−２を接続し、屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｂが完成する。
【００５９】
この際のバルコニー取付可能な建物２ｂにバルコニーＡ４ｂ−１やバルコニーＢ４ｂ−２を接続するバルコニー４ｂの接続方法および作用について説明する。
バルコニーＡ４ｂ−１を、実施例１と同様に、バルコニー支持梁４１ｂの屋内側端面に取り付けられている接続板４８ｂと短辺の床梁２２ｂの接続板とを柱２１ｂを挟んで対峙させ、短辺の床梁２２ｂの接続板から柱２１ｂを経てバルコニー支持梁４１ｂの接続板４８ｂにボルト８ｂを貫通させ、このボルトにナットを螺合させて、バルコニー取付可能な建物ユニット２ｂに取り付ける。
【００６０】
又、バルコニーＢ４ｂ−２を、バルコニー支持梁４１ｂの屋内側端面に取り付けられている接続板４８ｂと長辺の床梁２２ｂの接続板とを柱２１ｂを挟んで対峙させ、長辺の床梁２２ｂの接続板から柱２１ｂを経てバルコニー支持梁４１ｂの接続板４８ｂにボルトを貫通させ、このボルトにナットを螺合させて、バルコニー取付可能な建物ユニット２ｂに取り付ける。
【００６１】
そして、バルコニーＡ４ｂ−１のバルコニー支持梁４１ｂとバルコニーＢ４ｂ−２の延長屋内側梁４４ｂとを連結する。
すると、バルコニーＡ４ｂ−１とバルコニーＢ４ｂ−２の床材４７ｂ（バルコニー４ｂの床）と、このバルコニー４ｂに続くバルコニー取付可能な建物ユニット２ｂの床材（接続空間部Ｓｂの床）とがほぼ同じ高さになり、ここに連続した拡大空間の床が形成される。
【００６２】
このようにして完成したユニット建物Ｕｂでは、図１２に示すように、バルコニーＡ４ｂ−１とバルコニーＢ４ｂ−２には、それぞれ突出方向に向けて２本のバルコニー支持梁４１ｂが設けられ、この２本のバルコニー支持梁４１ｂとバルコニー取付可能な建物ユニット２ｂの短辺の床梁２２ｂや長辺の床梁２２ｂとが柱２１ｂを挟んでほぼ同一直線上に連結されているから、この柱２１ｂを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｂと短辺の床梁２２ｂとが、又、バルコニー支持梁４１ｂと長辺の床梁２２ｂとが、それぞれあたかも１本の梁のようになる。
【００６３】
従って、柱２１ｂに作用する曲げモーメントが減少し、バルコニー支持梁４１ｂが片持式の梁であっても、両方のバルコニー４ｂに設けられているそれぞれの２本のバルコニー支持梁４１ｂでバルコニーＡ４ｂ−１やバルコニーＢ４ｂ−２の荷重を支えることができ、バルコニーＡ４ｂ−１やバルコニーＢ４ｂ−２が屋外方向にある程度長く突出してたり、ある程度重いものでも支障がない。
【００６４】
又、このバルコニーＡ４ｂ−１の接続構造では、補助梁がないので、従来の補助梁を備えたバルコニー取付可能な建物ユニットより安価になる。又、建物ユニット１ｂの床梁を、接続板を設けた床梁に替えるだけで、建物ユニット１ｂとほぼ同じ構造の骨格をバルコニー取付可能な建物ユニット２ｂの骨格に使用することができ、更に、安価になる。
【００６５】
更に、上記効果に加えて、コ字形の正面外壁９１ｂ、袖壁９２ｂで区切られた部分にバルコニーに続く接続空間部Ｓｂが形成され、この接続空間部Ｓｂと、バルコニー４ｂの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。
【００６６】
（実施例４）
図１４〜図１７は本発明の更に別の実施例を示すもので、図１４はユニット建物の主要部を示す斜視図、図１５はユニット建物の主要部を構造材のみで示す平面図、図１６（イ）はバルコニーＡを示す一部切欠斜視図、（ロ）はバルコニーＢを示す一部切欠斜視図、図１７は図１４のＤ−Ｄ線における断面図である。
【００６７】
この図１４〜図１７に示す実施例４を図１〜図７に示す実施例１と比較すると、バルコニー４ｃがバルコニーＡ４ｃ−１とバルコニーＢ４ｃ−２の２種類あること、バルコニー取付可能なユニット建物２ｃも建物ユニットＡ２ｃ−１と建物ユニットＢ２ｃ−２の２種類あること、そして、建物ユニットＡ２ｃ−１にはバルコニーＡ４ｃ−１が、又、建物ユニットＢ２ｃ−２にはバルコニーＢ４ｃ−２がそれぞれ取り付けられていることが異なる。
即ち、ユニット建物Ａ２ｃ−１の骨格は、実施例３のバルコニー取付可能な建物ユニットの骨格とほぼ同じである。
【００６８】
そして、図１４、図１５に示すように、このユニット建物Ａ２ｃ−１の屋外側の短辺と長辺に外壁９ｃが取り付けられ、この屋外側の長辺と短辺の外壁９ｃにそれぞれ開口９７ｃ、９８ｃが設けられ、床小梁２３ｃに立設された正面外壁９１ｃと、床小梁２３ｃと隣接する建物ユニット１ｃとの間の短辺の床梁２２ｃに立設さた袖壁９２ｂとでＬ字形の外壁９ｃが設けられ、この正面外壁９１ｃに開口９５ｃが設けられ、この開口９５ｃに窓９６ｃが取り付けられ、この正面外壁９１ｃと外壁９ｃとの間に廊下状の接続空間部Ｓｃが形成されている。
【００６９】
又、ユニット建物Ｂ２ｃ−２は、図１５に示すように、四隅に立設された柱２１ｃと、この柱２１ｃの下端部に差し渡された床梁２２ｃと、相対する長辺の床梁２２ｃ、２２ｃに差し渡されて取り付けられた床小梁２３ｃと、外壁９ｃ近傍の短辺の床梁２２ｃと床小梁２３ｃに差し渡された補助梁５ｃとからなる骨格を備えている。その他は実施例１とほぼ同じ構造をしている。
【００７０】
尚、この補助梁５ｃは床梁２２ｃとほぼ同じ断面形状であり、この補助梁５ｃは、図１７に示すように、接続板５８ｃを介して短辺の床梁２２ｃや床小梁２３ｃに接続されている。
このように、補助梁５ｃの断面形状が床梁２２ｃや床小梁２３ｃの断面形状とほぼ同じであるので、補助梁５ｃが床梁２２ｃとほぼ同じ程度の機械的強度を有し、この補助梁５ｃに接続されるバルコニー支持梁４１ｃの曲げモーメントに対する抵抗性が床梁２２ｃとほぼ同じだけ大きくなるし、補助梁５ｃを床梁２２ｃや床小梁２３ｃに接続し易くなる。
【００７１】
バルコニーＡ４ｃ−１は、図１６（イ）に示すように、２本のバルコニー支持梁４１ｃと、この２本の支持梁４１ｃの屋内側端部を連結する屋内側梁４２ｃと、２本のバルコニー支持梁４１ｃの屋外側端部を連結する軒先梁４３ｃとからなる骨格を備えている。
尚、このバルコニー支持梁４１ｃの屋内側端面には接続板４８ｃが取り付けられている。
【００７２】
そして、このバルコニーＡ４ｃ−１は、屋内側梁４２ｃと軒先梁４３ｃの上に床根太４６ｃが架け渡されて取り付けられ、この床根太４６ｃの上にバルコニー床材４７ｂｃ設けられて床が設けられ、端側のバルコニー支持梁４１ｃと軒先梁４３ｃの上にＬ字形に手摺り４９ｃが立設されたものである。
バルコニーＢ４ｃ−２は、バルコニーＡ４ｃ−１より短く、手摺り４９ｃの開口の方向が逆になっていることが異なるだけである。
【００７３】
即ち、バルコニーＢ４ｃ−２は、図１６（ロ）に示すように、２本のバルコニー支持梁４１ｃと、この２本の支持梁４１ｃの屋内側端部を連結する屋内側梁４２ｃと、２本のバルコニー支持梁４１ｃの屋外側端部を連結する軒先梁４３ｃとからなる骨格を備え、このバルコニー支持梁４１ｃの屋内側端面には接続板４８ｃが取り付けられ、このバルコニーＢ４ｃ−２は、屋内側梁４２ｃと軒先梁４３ｃの上に根太４６ｃが架け渡されて取り付けられ、この根太４６ｃの上にバルコニー床材４７ｂｃ設けられて床が形成され、端側のバルコニー支持梁４１ｃと軒先梁４３ｃの上に手摺り４９ｃが立設されたものである。
【００７４】
その他の構造は実施例１とほぼ同じであるので、説明を省略する。
このユニット建物Ｕｃの施工方法は、実施例１とほぼ同じように、工場で、建物ユニット１ｃ、建物ユニットＡ２ｃ−１、建物ユニットＢ２ｃ−２、バルコニーＡ４ｃ−１、バルコニーＢ４ｃ−２、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ｃ、建物ユニットＡ２ｃ−１、建物ユニットＢ２ｃ−２を据え付け、建物ユニットＡ２ｃ−１と建物ユニットＢ２ｃ−２にそれぞれバルコニーＡ４ｃ−１、バルコニーＢ４ｃ−２を接続し、屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｃが完成する。
【００７５】
この際のバルコニーＡ４ｃ−１、バルコニーＢ４ｃ−２の接続方法および作用について説明する。
実施例１と同様にして、バルコニーＡ４ｃ−１の２本のバルコニー支持梁４１ｃの屋内側端面に取り付けられている接続板４８ｃと長辺の床梁２２ｃの接続板とを柱２１ｃを挟んで対峙させ、長辺の床梁２２ｃの接続板からバルコニー支持梁４１ｃの接続板４８ｃにボルトを貫通させ、このボルトにナットを螺合させて、バルコニーＡ４ｃ−１を建物ユニットＡ２ｃ−１に取り付ける。
【００７６】
又、上記バルコニーＡ４ｃ−１と同様に、バルコニーＢ４ｃ−２の２本の中の１本のバルコニー支持梁４１ｃの屋内側端面に取り付けられている接続板４８ｃと長辺の床梁２２ｃの接続板とを柱２１ｃを挟んで対峙させ、長辺の床梁２２ｃの接続板から柱２１ｃを経てバルコニー支持梁４１ｃの接続板４８ｃにボルトを貫通させ、このボルトにナットを螺合させ、又、図１７に示すように、他の１本のバルコニー支持梁４１ｃの屋内側端面に取り付けられている接続板４８ｃと補助梁５ｃの接続板５８ｃとを短辺の床梁２２ｃを挟んで対峙させ、補助梁５ｃの接続板５８ｃから床梁２２ｃを経てバルコニー支持梁４１ｃの接続板４８ｃにボルト８ｃを貫通させ、このボルト８ｃにナット８１ｃを螺合させて、バルコニーＢ４ｃ−２を建物ユニットＢ２ｂ−２に取り付ける。
【００７７】
そして、バルコニーＡ４ｃ−１のバルコニー支持梁４１ｃとバルコニーＢ４ｃ−２のバルコニー支持梁４１ｃを連結する。
すると、図１７に示すように、バルコニーＡ４ｃ−１とバルコニーＢ４ｃ−２の床材４７ｃ（バルコニー４ｃの床）と、このバルコニー４ｃに続く廊下９６ｃの床材２６ｃ（接続空間部Ｓｃの床）とがほぼ同じ高さになり、連続した拡大空間の床が形成される。
【００７８】
このようして完成したユニット建物Ｕｃでは、図１５に示すように、バルコニーＡ４ｃ−１には、突出方向に向けて２本のバルコニー支持梁４１ｃが設けられ、この２本のバルコニー支持梁４１ｃと２本の長辺の床梁２２ｃとが、それぞれ別々に柱２１ｃを挟んで、若干高さが異なるがほぼ同一直線上に連結されているから、この柱２１ｃを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｃと長辺の床梁２２ｃが、あたかも１本の梁のようになる。
【００７９】
従って、柱２１ｃに作用する曲げモーメントが減少し、バルコニー支持梁４１ｃが片持式の梁であっても、この２本のバルコニー支持梁４１ｃでバルコニーＡ４ｃ−１の荷重を支えることができ、バルコニーＡ４ｃ−１が屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
【００８０】
又、バルコニーＢ４ｃ−２には、バルコニーＢ４ｃ−２に突出方向に向けて２本のバルコニー支持梁４１ｃが設けられ、この中の１本のバルコニー支持梁４１ｃと１本の長辺の床梁２２ｃとが柱２１ｃを挟んで、又、他の１本のバルコニー支持梁４１ｃと補助梁５ｃとが短辺の床梁２２ｃを挟んで、それぞれほぼ同一直線上に連結されているから、この柱２１ｃや床梁２２ｃを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｃと長辺の床梁２２ｃや補助梁５ｃが、あたかも１本の梁のようになる。
【００８１】
従って、柱２１ｃや床梁５ｃに作用する曲げモーメントが減少し、バルコニー支持梁４１ｃが片持式の梁であっても、この２本のバルコニー支持梁４１ｃでバルコニーＢ４ｃ−２の荷重を支えることができ、バルコニーＢ４ｃ−２が屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
【００８２】
又、このバルコニーＡ４ｃ−１、バルコニーＢ４ｃ−２の接続構造では、補助梁５ｃを１本だけ使用しているので、従来の４本のバルコニー支持梁４１ｃに接続するために、４本の補助梁を設けるバルコニー取付可能な建物ユニットより安価になる。
更に、Ｌ字形の正面外壁９１ｃと袖壁９２ｃで区切られた部分にバルコニーに続く接続空間部Ｓｃが形成され、この接続空間部Ｓｃと、バルコニー４ｃの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。

（実施例５）
図１８〜図２１は本発明の更に別の実施例を示すもので、図１８はユニット建物の主要部を示す斜視図、図１９はユニット建物の主要部を骨格のみで示す平面図、図２０はバルコニー取付可能な建物ユニットの骨格を示す斜視図、図２１は図１９のＦ−Ｆ線における断面図である。
【００８４】
この図１８〜図２１に示す実施例５を図１〜図７に示す実施例１と比較すると、バルコニー取付可能なユニット建物２ｄとバルコニー４ｄの構造が異なる。
即ち、バルコニー取付可能なユニット建物２ｄは、図１９、２０に示すように、矩形の四隅に配置された柱２１ｄと、短辺の床梁２２ｄのほぼ中央部に立設けられた柱２１ｄと、この柱２１ｄの下端部を矩形の辺に沿って連結する床梁２２ｄと、この短辺のほぼ中央部に立設された柱２１ｄの下端部を連結する床梁２２ｄ−１と、この床梁２２ｄ−１と長辺の床梁２２ｄとに差し渡された補助梁５ｄとからなる骨格を備えている。
【００８５】
そして、図１８に示すように、隣接する建物ユニット１ｄから屋外側の短辺の中央部に立設けられた柱２１ｄまでに外壁９ｄが設けられ、床梁２２ｄ−１の上に正面外壁９１ｄが設けられ、この正面外壁９１ｄの端から隣接する建物ユニット１ｄとの境界に沿って袖壁９２ｄが設けられていて、このＬ字形になっている正面外壁９１ｄと袖壁９２ｄとに囲まれた部分に接続空間部Ｓｃが形成され、この外壁のない屋外側長辺部分の大部分にバルコニー４ｄが取り付けられ、残りの外壁９ｄのない屋外縁部分に手摺り２０ｄが設けられている。
尚、この正面外壁９１ｄには開口９５ｄが設けられ、この開口９５ｄには窓９６ｄが取り付けられている。
【００８６】
又、補助梁５ｄの断面形状は床梁２２ｄの断面形状とほぼ同じである。
このように、補助梁５ｄの断面形状と床梁２２ｄの断面形状とがほぼ同じ形状であるので、補助梁５ｄが床梁２２ｄとほぼ同じ程度の機械的強度を有し、この補助梁５ｄに接続されるバルコニー支持梁４１ｄの曲げモーメントに対する抵抗性が床梁２２ｄとほぼ同じになるし、補助梁５ｄを床梁２２ｄに接続し易くなる。
その他は実施例１の建物ユニットとほぼ同じ構造である。
バルコニー４ｄは、実施例１とほぼ同じ構造をしているが、長さが短いことが異なるだけであかるので、説明を省略する。
その他の構造は実施例１とほぼ同じであるので、説明を省略する。
【００８７】
次に、このユニット建物Ｕｄの施工方法について説明する。
このユニット建物Ｕｄの施工方法は、実施例１とほぼ同じように、工場で、建物ユニット１ｄ、バルコニー取付可能な建物ユニット２ｄ、バルコニー４ｄ、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ｄ、バルコニー取付可能な建物ユニット２ｄを据え付け、このバルコニー取付可能な建物ユニット２ｄにバルコニー４ｄを接続し、屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｄが完成する。
【００８８】
この際のバルコニー４ｄをバルコニー取付可能な建物ユニット２ｄに接続するバルコニー４ｄの接続方法および作用について説明する。
実施例２と同様に、図１９に示すように、バルコニー支持梁４１ｄの１本の屋内側端面に取り付けられている接続板と短辺の床梁２２ｄの接続板とを柱２１ｄを挟んで対峙させ、長辺の床梁２２ｄの接続板から柱２１ｄを経てバルコニー支持梁４１ｄの接続板にボルトを貫通させ、このボルトにナットを螺合させ、又、図１９、図２１に示すように、バルコニー支持梁４１ｄの他の１本の屋内側端面に取り付けられている接続板４８ｄの補助梁５ｄの接続板５８ｄとを短辺の床梁２２ｄを挟んで対峙させ、補助梁５ｄの接続板５８ｄからバルコニー支持梁４１ｄの接続板４８ｄにボルト８ｄを貫通させ、このボルト８ｄにナット８１ｄを螺合させて、バルコニー４ｄを建物ユニット２ｄに取り付ける。
【００８９】
すると、バルコニー４ｄの床材４７ｄ（バルコニー４ｄの床）と、このバルコニー４ｄに続くバルコニー取付可能な建物ユニット２ｄの床材２６ｄ（接続空間部Ｓｄの床）とがほぼ同じ高さになり、連続した拡大空間の床が形成される。
【００９０】
このようにして完成したユニット建物Ｕｄでは、図１９に示すように、バルコニー４ｄには、それぞれ突出方向に向けて２本のバルコニー支持梁４１ｄが設けられ、この中の１本のバルコニー支持梁４１ｄと建物ユニット２ｄの短辺の床梁２２ｄとが柱２１ｄを挟んで、又、他の１本のバルコニー支持梁４１ｄと補助梁５ｄとが長辺の床梁２２ｄを挟んで、若干高さが異なるが、それぞれほぼ同一直線上に連結されているから、この柱２１ｄや床梁２２ｄを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｄと長辺の床梁２２ｄや補助梁５ｄが、あたかも１本の梁のようになる。
【００９１】
従って、柱２１ｄや床梁５ｄに作用する曲げモーメントが減少し、バルコニー支持梁４１ｄが片持式の梁であっても、この２本のバルコニー支持梁４１ｄでバルコニー４ｄの荷重を支えることができ、バルコニー４ｄが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
【００９２】
又、このバルコニーＡ４ｄ−１、バルコニーＢ４ｄ−２の接続構造では、補助梁５ｄが１本だけ設けられているので、従来の２本のバルコニー支持梁４１ｄには２本の補助梁を備える必要なバルコニー取付可能な建物ユニットより安価になる。
更に、正面外壁９１ｄと袖壁９２ｄで区切られた部分にバルコニーに続く接続空間部Ｓｄが形成され、この接続空間部Ｓｄと、バルコニー４ｄの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。

図２２〜図２４は本発明の更に別の実施例を示すもので、図２２はユニット建物の主要部を示す斜視図、図２３はバルコニー取付可能な建物ユニットの骨格を示す斜視図、図２４はユニット建物の主要部を構造材のみで示す平面図である。
【００９４】
この図２２〜図２４に示す実施例６を図１〜図７に示す実施例１と比較すると、バルコニー取付可能なユニット建物２ｅと、バルコニー４ｅの構造が異なる。
即ち、ユニット建物２ｅは、図２３に示すように、矩形の四隅に配置された柱２１ｅや柱取付筒２１ｅ−１と、相対する長辺のほぼ中間部に立設けられた柱２１ｅと、この柱２１ｅや柱取付筒２１ｅ−１の下端部を矩形の辺に沿って連結する床梁２２ｅと、この長辺の中間部に立設された柱２１ｅの下端部を連結する床梁２２ｅ−１と、長辺の相対する床梁２２ｅのほぼ中間部に差し渡された補助梁５ｅとからなる骨格を備えている。
【００９５】
尚、この柱取付筒２１ｅ−１は下階の柱を取り付けるものである。
そして、図２２に示すように、隣接する建物ユニット１ｅから屋外側の長辺の中間部に立設けられた柱２１ｅまでに外壁９ｅが設けられ、床梁２２ｅ−１の上に正面外壁９１ｅが設けられ、この正面外壁９１ｅの端から隣接する建物ユニット１ｅとの境界に沿って袖壁９２ｅが設けられていて、このＬ字形になっている正面外壁９１ｅと袖壁９２ｅとに囲まれた部分に接続空間部Ｓｅが形成されている。そして、屋外側長辺の外壁のない部分から外壁９ｅの中間部までにバルコニー４ｅが取り付けられ、残りの外壁のない部分の短辺の床梁２２ｅの上に手摺り２０ｅが設けられている。
【００９６】
尚、この正面外壁９１ｅには開口９５ｅが設けられ、この開口９５ｅには窓９６ｅが取り付けられている。
又、補助梁５ｅの断面形状は床梁２２ｅの断面形状とほぼ同じである。
このように、補助梁５ｅの断面形状と床梁２２ｅの断面形状とがほぼ同じに形状であるので、補助梁５ｅが床梁２２ｅとほぼ同じ程度の機械的強度を有し、この補助梁５ｅに接続されるバルコニー支持梁４１ｅの曲げモーメントに対する抵抗性が床梁２２ｅとほぼ同じになるし、補助梁５ｅを床梁２２ｅに接続し易くなる。
その他は実施例１の建物ユニットとほぼ同じ構造である。
【００９７】
バルコニー４ｅは、実施例５に示すバルコニーとほぼ同じであるので説明を省略する。
その他の構造は実施例１とほぼ同じである。
【００９８】
次に、このユニット建物Ｕｅの施工方法について説明する。
このユニット建物Ｕｅの施工方法は、実施例１とほぼ同じように、工場で、建物ユニット１ｅ、バルコニー取付可能な建物ユニット２ｅ、バルコニー４ｅ、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ｅ、バルコニー取付可能な建物ユニット２ｅを据え付け、このバルコニー取付可能な建物ユニット２ｅにバルコニー４ｅを接続し、建物ユニット１ｅとバルコニー取付可能な建物ユニット２ｅの上に屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｅが完成する。
【００９９】
この際のバルコニー４ｅをバルコニー取付可能な建物ユニット２ｅに接続するバルコニー４ｅの接続方法および作用について説明する。
【０１００】
実施例５と同様に、２本の中の１本のバルコニー支持梁４１ｅの屋内側端面に取り付けられている接続板と短辺の床梁２２ｅの接続板とを柱取付筒２１ｅ−１を挟んで対峙させ、短辺の床梁２２ｅの接続板から柱取付筒２１ｅ−１を経てバルコニー支持梁４１ｅの接続板にボルトを貫通させ、このボルトにナットを螺合させ、又、他の１本のバルコニー支持梁４１ｅの屋内側端面に取り付けられている接続板と補助梁５ｅの接続板とを短辺の床梁２２ｅを挟んで対峙させ、補助梁５ｅの接続板から床梁２２ｅを経てバルコニー支持梁４１ｅの接続板にボルトを貫通させ、このボルトにナットを螺合させて、バルコニー４ｅをバルコニー取付可能な建物ユニット２ｅに取り付ける。
【０１０１】
その後、バルコニー４ｅの屋内側梁４２ｅとバルコニー４ｅのバルコニー支持梁４１ｅを連結する。
【０１０２】
このようにして完成したユニット建物Ｕｅでは、図２４に示すように、バルコニー４ｅには、突出方向に向けて２本のバルコニー支持梁４１ｅが設けられ、この中の１本のバルコニー支持梁４１ｅと１本の短辺の床梁２２ｅとが柱取付筒２１ｅ−１を挟んで、又、他の１本のバルコニー支持梁４１ｅと補助梁５ｅとが長辺の床梁２２ｃを挟んで、それぞれほぼ同一直線上に連結されているから、この柱取付筒２１ｅ−１や床梁２２ｅを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｅと短辺の床梁２２ｅや補助梁５ｅが、あたかも１本の梁のようになる。
【０１０３】
従って、柱２１ｅや床梁５ｅに作用する曲げモーメントが減少し、バルコニー支持梁４１ｅが片持式の梁であっても、この２本のバルコニー支持梁４１ｅでバルコニーＡ４ｅ−１の荷重を支えることができ、バルコニー４ｅが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
又、このバルコニー４ｅの接続構造では、補助梁５ｅを１本だけ使用しているので、従来の２本のバルコニー支持梁４１ｅに接続するために、２本の補助梁を設けるバルコニー取付可能な建物ユニットより安価になる。
【０１０４】
又、建物ユニット１ｅの床梁を、接続板を取り付けた床梁２２ｅに替えるだけで建物ユニット１ｅの骨格をバルコニー取付可能な建物ユニット２ｅの骨格に使用することができ、更に安価になる。
又、正面外壁９１ｅと袖壁９２ｅで区切られた部分にバルコニーに続く接続空間部Ｓｅが形成され、この接続空間部Ｓｅと、バルコニー４ｅの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。

図２５〜図２７は本発明の更に別の実施例を示すもので、図２５はユニット建物の主要部を示す斜視図、図２６はバルコニー取付可能な建物ユニットの骨格を示す斜視図、図２７はユニット建物の主要部を構造材のみで示す平面図である。
【０１０６】
この図２５〜図２７に示す実施例７を図１〜図７に示す実施例１と比較すると、バルコニー取付可能なユニット建物２ｆとバルコニー４ｆの構造が異なる。
即ち、ユニット建物２ｆは、図２６、図２７に示すように、矩形の四隅に配置された柱２１ｆと、相対する長辺の床梁２２ｆの中間部に立設けられた柱２１ｆと、この柱２１ｆの下端部を連結する床梁２２ｆと、長辺に立設された柱２１ｆの下端部を連結する床梁２２ｆ−１とからなる骨格を備えている。
【０１０７】
そして、図２５に示すように、隣接する建物ユニット１ｆから屋外側の長辺の中間部に立設された柱２１ｆまでの床梁２２ｆ−１の上に外壁９ｆが設けられ、床梁２２ｆ−１の上に正面外壁９１ｆが設けられ、この正面外壁９１ｆの端から隣接する建物ユニット１ｆとの境界に沿って袖壁９２ｆが設けられていて、このＬ字形に立設されている正面外壁９１ｆと袖壁９２ｆとに囲まれた部分に接続空間部Ｓｆが形成され、屋外側長辺の外壁のない部分に手摺り２０ｆが設けられている。そして、外側の短辺にバルコニー４ｆが取り付けられる。
【０１０８】
尚、この正面外壁９１ｆには開口９５ｆが設けられ、この開口９５ｆには窓９６ｆが取り付けられている。
その他は実施例１の建物ユニットとほぼ同じ構造である。
バルコニー４ｆは、長さがバルコニー取付可能な建物ユニット２ｆの短辺の長さとほぼ同じであることが実施例１のバルコニーと異なるだけであるので、説明を省略する。
その他の構造は実施例１とほぼ同じである。
【０１０９】
次に、このユニット建物Ｕｆの施工方法について説明する。
このユニット建物Ｕｆの施工方法は、実施例１とほぼ同じように、工場で、建物ユニット１ｆ、バルコニー取付可能な建物ユニット２ｆ、バルコニー４ｆ、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ｆ、バルコニー取付可能な建物ユニット２ｆを据え付け、このバルコニー取付可能な建物ユニット２ｆにバルコニー４ｆを接続し、建物ユニット１ｆとバルコニー取付可能な建物ユニット２ｆの上に屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｆが完成する。
【０１１０】
この際のバルコニー４ｆをバルコニー取付可能な建物ユニット２ｆに接続するバルコニー４ｆの接続方法および作用について説明する。
実施例４と同様に、バルコニー支持梁４１ｆの屋内側端面に取り付けられている接続板と長辺の床梁２２ｆの接続板とを柱２１ｆを挟んで対峙させ、短辺の床梁２２ｆの接続板から柱２１ｆを経てバルコニー支持梁４１ｆの接続板にボルトを貫通させ、このボルトにナットを螺合させて、バルコニー４ｆを建物ユニット２ｆに取り付ける。
【０１１１】
このようにして完成したユニット建物Ｕｆでは、図２７に示すように、バルコニー４ｆには、突出方向に向けて２本のバルコニー支持梁４１ｆが設けられ、バルコニー支持梁４１ｆと長辺の床梁２２ｆとが柱２１ｆを挟んでほぼ同一直線上に連結されているから、この柱２１ｆを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｆと長辺の床梁２２ｆが、あたかも１本の梁のようになる。
従って、柱２１ｆや床梁５ｆに作用する曲げモーメントが減少し、バルコニー支持梁４１ｆが片持式の梁であっても、この２本のバルコニー支持梁４１ｆでバルコニー４ｆの荷重を支えることができ、バルコニー４ｆが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
【０１１２】
又、このバルコニー４ｆでは、補助梁５ｅを使用しないので、従来の２本のバルコニー支持梁４１ｆに接続するために、２本の補助梁を設けるバルコニー取付可能な建物ユニットより安価になる。
又、建物ユニット１ｆの床梁を、接続板を取り付けた床梁に替えるだけで建物ユニット１ｆの骨格をバルコニー取付可能な建物ユニット２ｆの骨格に使用すくことができ、更に安価になる。
【０１１３】
更に、正面外壁９１ｆと袖壁９２ｆで区切られた部分にバルコニーに続く接続空間部Ｓｆが形成され、この接続空間部Ｓｆと、バルコニー４ｆの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。
【０１１４】
（実施例８）
図２８〜図３０は本発明の更に別の実施例を示すもので、図２８はユニット建物の主要部を示す斜視図、図２９はバルコニー取付可能な建物ユニットの骨格を示す斜視図、図３０はユニット建物の主要部を構造材のみで示す平面図である。
【０１１５】
この図２８〜図３０に示す実施例８を図１〜図７に示す実施例１と比較すると、バルコニー取付可能なユニット建物２ｇとバルコニー４ｇの構造が異なる。
即ち、バルコニー取付可能なユニット建物２ｇは、図２９、３０に示すように、矩形の四隅に配置された柱２１ｇや柱取付筒２１ｇ−１と、この柱２１ｇの下端部や柱取付筒２１ｇ−１を矩形の辺に沿って連結する床梁２２ｇと、相対する長辺の床梁２２ｇに柱取付筒２ｇ−１を挟んで接続された延長部屋支持梁６ｇと、この延長部屋支持梁６ｇの先端を結ぶ連結梁６１ｇと、延長部屋支持梁６ｇと連結梁６１ｇとの交点に立設された柱２４ｇと、相対する長辺の床梁２２ｇに差し渡されて取り付けられている補助梁５ｇとからなる骨格を備えている。
【０１１６】
この柱取付筒２１ｇ−１は下階の柱を取り付けるものである。
そして、図２８に示すように、外側の長辺の床梁２２ｇと２本の延長部屋支持梁６ｇと連結梁６１ｇの上に外壁９ｇが取り付けられている。尚、長辺の床梁２２ｇの上に取り付けられた外壁９ｇには、開口９５ｇが設けられ、この開口９５ｇには窓９６ｇが取り付けられている。
又、柱２１ｇや柱２４ｇの上端部に、図２９の点線で示す天井パネル２７ｇが取り付けられている。
【０１１７】
尚、補助梁５ｇの断面形状は床梁２２ｇの断面形状とほぼ同じである。
このように、補助梁５ｇの断面形状と床梁２２ｇの断面形状とがほぼ同じ形状であるので、補助梁５ｇが床梁２２ｇとほぼ同じ程度の機械的強度を有し、この補助梁５ｇに接続されるバルコニー支持梁４１ｇの曲げモーメントに対する抵抗性が床梁２２ｇとほぼ同じになるし、補助梁５ｇを床梁２２ｇに接続し易くなる。
バルコニー４ｇの構造は実施例３のバルコニーＢとほぼ同じ構造をしている。
その他は実施例１のバルコニー取付可能な建物ユニットとほぼ同じ構造である。
【０１１８】
次に、このユニット建物Ｕｇの施工方法について説明する。
このユニット建物Ｕｇの施工方法は、工場で、建物ユニット１ｇ、バルコニー取付可能な建物ユニット２ｇ、バルコニー４ｇ、屋根パネル等を製造する。
この際のバルコニー取付可能な建物ユニット２ｇとバルコニー４ｇの製造方法を説明する。
即ち、図２９に示すように、矩形の四隅に柱２１ｇと柱取付筒２１ｇ−１を配置し、この柱２１ｇの下端部と柱取付筒２１ｇを矩形の辺に沿って床梁２２ｇで連結し、長辺の床梁２２ｇと部屋支持梁６ｇとが柱取付筒２１ｇ−１を挟んでほぼ一直線上になるようにして延長部屋支持梁６ｇを柱取付筒２１ｇ−１に溶接して取り付け、この延長部屋支持梁６ｇの先端に柱２４ｇを立設させ、この柱２４ｇを連結梁６１ｇで結び、相対する長辺の床梁２２ｇに補助梁５ｇを差し渡して取り付けて、バルコニー取付可能な建物ユニット２ｇの骨格を製造する。
【０１１９】
このようにすると、建物ユニット２ｇの骨格では、長辺の床梁２２ｇには、突出方向に向けて２本の延長部屋支持梁６ｇが設けられ、この延長部屋支持梁６ｇが柱取付筒２１ｇ−１を挟んでほぼ一直線上に溶接され連結されているから、図３０に示すように、この柱２１ｇを挟んでほぼ同一直線上に連結さている延長部屋支持梁６ｇと長辺の床梁２２ｇが、あたかも１本の梁のようになる。
そして、柱２１ｇと柱２４ｇの上に天井パネル２７ｇを取り付け、外側の長辺の床梁２２ｇと部屋支持梁６ｇと連結梁６１ｇの上に外壁９ｇを取り付けてバルコニー取付可能な建物ユニット２ｇを製造する。
【０１２０】
尚、長辺の床梁２２ｇの上に取り付けられた外壁９ｇには、予め、開口９５ｇを設けたものを使用し、この開口９５ｇには窓９６ｇを取り付ける。
又、実施例１と同様にしてバルコニー４ｇを製造する。
このようにして製造した建物ユニット１ｇ、バルコニー取付可能な建物ユニット２ｇ、バルコニー４ｇ、屋根パネル等を施工現場に運搬し、施工現場では、予め設けられている基礎の上に建物ユニット１ｇ、バルコニー取付可能な建物ユニット２ｇを据え付け、このバルコニー取付可能な建物ユニット２ｇにバルコニー４ｇを取り付け、屋根パネルを取り付け、種々な仕上げを行うと、ユニット建物Ｕｇが完成する。
【０１２１】
この際のバルコニー４ｇをバルコニー取付可能な建物ユニット２ｇに取り付けるバルコニー４ｇの接続方法について説明する。
２本の中の１本のバルコニー支持梁４１ｇの屋内側端面に取り付けられている接続板と短辺の床梁２２ｇの接続板とを柱２１ｇを挟んで対峙させ、短辺の床梁２２ｇの接続板から柱２１ｇを経てバルコニー支持梁４１ｇの接続板にボルトを貫通させ、このボルトにナットを螺合させ、又、バルコニー支持梁４１ｇの他の１本の屋内側端面に取り付けられている接続板と補助梁５ｇの接続板とを短辺の床梁２２ｇを挟んで対峙させ、補助梁５ｇの接続板から床梁２２ｇを経てバルコニー支持梁４１ｇの接続板にボルトを貫通させ、このボルトにナットを螺合させて、バルコニー４ｇを建物ユニット２ｇに取り付ける。
【０１２２】
次に、このユニット建物Ｕｇの作用について説明する。
このようにして完成したユニット建物Ｕｇでは、バルコニー取付可能な建物ユニット２ｇが、柱取付筒２ｇ−１が下階の柱の上に載った状態に、据え付けられ、この柱取付筒２ｇ−１より先端部分に、下階から突出した延長部屋Ｓｇ−１が形成される。
そして、図３０に示すように、この柱取付筒２１ｇ−１を挟んでほぼ同一直線上に連結さている延長部屋支持梁６ｇと長辺の床梁２２ｇが、あたかも１本の梁のようになっているので、柱２１ｇに作用する曲げモーメントが減少し、延長部屋支持梁６ｇが片持式の梁であっても、この２本の延長部屋支持梁６ｇで、この延長部屋Ｓｇ−１の荷重を支えることができる。
【０１２３】
又、バルコニー４ｇには、突出方向に向けて２本のバルコニー支持梁４１ｇが設けられ、図３０に示すように、この中の１本のバルコニー支持梁４１ｇと床梁２２ｇとが柱取付筒２１ｇ−１を挟んで、又、他の１本のバルコニー支持梁４１ｇと補助梁５ｇとが、長辺の床梁２２ｇを挟んで、それぞれほぼ同一直線上に連結されているから、この柱取付筒２１ｇ−１や床梁２２ｇを挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｇと連結梁６１ｇや補助梁５ｇが、あたかも１本の梁のようになる。
【０１２４】
従って、柱取付筒２１ｇ−１や床梁５ｇに作用する曲げモーメントが減少し、バルコニー支持梁４１ｇが片持式の梁であっても、この２本のバルコニー支持梁４１ｇでバルコニー４ｇの荷重を支えることができ、バルコニー４ｇが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
又、このバルコニー４ｇの接続構造では、補助梁５ｇを１本だけ使用しているので、従来の２本のバルコニー支持梁４１ｇに接続するために、２本の補助梁を設けるバルコニー取付可能な建物ユニットより安価になる。
【０１２５】

図３１〜図３３は本発明の更に別の実施例を示すもので、図３１はユニット建物の主要部を示す斜視図、図３２は建物ユニットの骨格を示す斜視図、図３３はユニット建物の主要部を構造材のみで示す平面図である。
【０１２６】
この図３１〜図３３に示す実施例９を図２８〜図３０に示す実施例８と比較すると、バルコニー取付可能なユニット建物の延長部屋が接続空間部Ｓｈとなっていることが異なる。
即ち、バルコニー取付可能な建物ユニット２ｈは、図３２に示すように、矩形の四隅に配置された柱２１ｈや柱取付筒２１ｈ−１と、この柱２１ｈの下端部や柱取付筒２１ｈ−１を連結する床梁２２ｈと、長辺の床梁２２ｈとほぼ一直線上になるように、柱２１ｈに接続された接続空間支持梁６ｈと、この接続空間支持梁６ｈの先端を結ぶ連結梁６１ｈと、相対する長辺の床梁２２ｈに差し渡されて取り付けられた補助梁５ｈとからなる骨格を備えている。
【０１２７】
この柱取付筒２１ｈ−１は手摺り２０ｈを取り付けるものである。
そして、図３１に示すように、バルコニー取付可能な建物ユニット２ｈは、屋外側の長辺の床梁２２ｈと、屋外側の短辺の床梁２２ｈの上に外壁９ｈが設けられ、端の屋外空間支持梁６ｈと連結梁６１ｈの上に手摺り２０ｈが設けられて、短辺の外壁９ｈと手摺り２０ｈの間に接続空間部Ｓｈが設けられたものである。
【０１２８】
又、柱２１ｈの上端部に図３２の点線で示すように天井パネル２７ｈを取り付ける。
尚、長辺の外壁９ｈと短辺の外壁９ｈには、それぞれ開口９５ｈが設けられ、この開口９５ｈに窓９６ｈが取り付けられている。
その他の構造は実施例８とほぼ同じであるので説明を省略する。
【０１２９】
又、実施例８の延長部屋支持梁が接続空間支持梁６ｈに替わり、この接続空間支持梁６ｈの上方に接続空間部Ｓｈが設けられているだけであって、実施例８と同じように施工できるし、作用もほぼ同じである。
【０１３０】

【０１３１】
この図３４および図３５に示す実施例１０を図１〜図７に示す実施例１と比較すると、バルコニー取付可能なユニット建物２ｊの構造が異なる。
即ち、バルコニー取付可能なユニット建物２ｊは、図３５に示すように、四隅に配置された柱取付筒２１ｊ−１と、この柱取付筒２１ｊ−１を連結する床梁２２ｊとからなる骨格を備えている（実施例１と比較すると、実施例１の柱の替わりに柱取付筒が設けられているし、この柱の上端部に取り付けられる天井がない）。
【０１３２】
尚、この柱取付筒２１ｊ−１は１階の建物ユニット１ｊの柱の上に取り付けるものである。
そして、このバルコニー取付可能な建物ユニット２ｊは、床梁２２ｊの上に床根太が架け渡されて取り付けられ、この上に塩化ビニル樹脂被覆鋼板の床材が取り付けられ、この上に塩化ビニル樹脂フィルムの防水シートが取り付けられているものである。尚、図３４に示すように、このバルコニー取付可能なユニット建物２ｊの長辺と隣接する建物ユニット１ｊとの境界部分に正面外壁９１ｊが立設され、短辺と隣接する建物ユニット１ｊとの境界部分に袖壁９２ｊが立設けられ、このＬ字形の正面外壁９１ｊと袖壁９２ｊで囲まれた部分に接続空間部Ｓｊが形成され、この正面外壁７１ｊに開口９５ｊが設けられ、この開口に窓９６ｊが取り付けられている。
その他は実施例１とほぼ同じ構造をしている。
【０１３３】
又、ユニット建物Ｕｊの施工方法および作用について説明する。
バルコニー取付可能な建物ユニット２ｊの製造方法は、四隅に柱取付筒２１ｊ−１を配置し、この柱取付筒２１ｊ−１を床梁２２ｊで連結して骨格を製造する。
そして、この床梁２２ｊの上に床根太を架け渡して取り付け、この上に塩化ビニル樹脂被覆鋼板の床材を取り付け、この上に塩化ビニル樹脂フィルムの防水シートを取り付けて、バルコニー取付可能な建物ユニット２ｊを製造する。
【０１３４】
その他の建物ユニット１ｊ、バルコニー４ｊ、屋根パネルはほぼ実施例１と同じようにして製造し、この建物ユニット１ｊ、バルコニー取付可能な建物ユニット２ｊ、バルコニー４ｊ、屋根パネル等を施工現場に運搬し、実施例と同様にして施工してユニット建物Ｕｊを完成させる。
【０１３５】
このようにして完成したユニット建物Ｕｊでは、図３５に示すように、バルコニー４ｊには、突出方向に向けて２本のバルコニー支持梁４１ｊが設けられ、この２本のバルコニー支持梁４１ｊと２本の短辺の床梁２２ｊとが、それぞれ別々に柱取付筒２１ｊ−１を挟んで、ほぼ同一直線上に連結されているから、この柱取付筒２１ｊ−１を挟んでほぼ同一直線上に連結さているバルコニー支持梁４１ｊと短辺の床梁２２ｊが、あたかも１本の梁のようになる。
【０１３６】
従って、柱２１ｊに作用する曲げモーメントが減少し、バルコニー支持梁４１ｊが片持式の梁であっても、この２本のバルコニー支持梁４１ｊでバルコニー４ｊの荷重を支えることができ、バルコニー４ｊが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
又、このバルコニー４ｊの接続構造では、建物ユニット２ｊには補助梁が備えられてないので、従来の２本のバルコニー支持梁４１ｊに接続するために、２本の補助梁を設けるバルコニー取付可能な建物ユニットより安価になる。
【０１３７】
更に、Ｌ字形の外壁７ｊで区切られた部分にバルコニーに続く接続空間部Ｓｊが形成され、この接続空間部Ｓｊと、バルコニー４ｊの空間とで連続した拡大空間が形成されているので、この形成された拡大空間は広く使用し易い。

その他の構造は実施例６とほぼ同じであるので説明を省略する。
【０１４０】
次に、このユニット建物Ｕｋの施工方法について説明する。
このユニット建物Ｕｋの施工方法は、実施例６とほぼ同じように、工場で、建物ユニット１ｋ、外廊下取付可能な建物ユニット２ｋ、外廊下４ｋ、屋外階段５５ｋ、屋根パネル等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎９９ｋの上に建物ユニット１ｋ、外廊下取付可能な建物ユニット２ｋを据え付け、この外廊下取付可能な建物ユニット２ｋに外廊下４ｋを接続し、この外廊下に屋外階段５５ｋを取り付け、建物ユニット１ｋと外廊下取付可能な建物ユニット２ｋの上に屋根パネル３ｋを取り付け、種々な仕上げを行うと、ユニット建物Ｕｋが完成する。
【０１４１】
この際の外廊下４ｋを外廊下取付可能な建物ユニット２ｋに取り付ける外廊下４ｋの接続方法および作用について説明する。
図３７に示すように、２本の中の１本の外廊下支持梁４１ｋの屋内側端面に取り付けられている接続板と短辺の床梁２２ｋの接続板とを柱取付筒２１ｋ−１を挟んで対峙させ、短辺の床梁２２ｋの接続板から柱取付筒２１ｋ−１を経て外廊下支持梁４１ｋの接続板にボルトを貫通させ、このボルトにナットを螺合させ、他の１本の外廊下支持梁４１ｋの屋内側端面に取り付けられている接続板と補助梁５ｋの接続板とを長辺の床梁２２ｋを挟んで対峙させ、補助梁５ｋの接続板から床梁２２ｋを経て外廊下支持梁４１ｋの接続板にボルトを貫通させ、このボルトにナットを螺合させて、外廊下４ｋを外廊下取付可能な建物ユニット２ｋに取り付ける。

【０１４３】
従って、柱２１ｋや床梁５ｋに作用する曲げモーメントが減少し、外廊下支持梁４１ｋが片持式の梁であっても、この２本の外廊下支持梁４１ｋで外廊下４ｋの荷重を支えることができ、外廊下４ｋが屋外方向にある程度長く突出したり、ある程度重いものでも支障がない。
又、この外廊下４ｋの接続構造では、補助梁５ｋを１本だけ使用しているので、従来の２本の外廊下支持梁４１ｋに接続するために、２本の補助梁を設ける外廊下取付可能な建物ユニットより安価になる。
【０１４４】

【０１４５】
この図３９〜図４２に示す実施例１２を図２２〜図２４に示す実施例６と比較すると、バルコニー取付可能なユニット建物２ｍとバルコニー４ｍがそれぞれ２個ずつあること、２個のバルコニーを連結床パネル６ｍで連結すること、このバルコニー取付可能なユニット建物２ｍとバルコニー４ｍの構造とが異なる。
即ち、この実施例１２に使用するバルコニー取付可能な建物ユニット２ｍには接続空間部がなく、外側に外壁９ｍが取り付けられている。そして、図３９に示すように、バルコニー取付可能な建物ユニット２ｍの２個が隣接して据え付けられ、バルコニー４ｍに対峙する外壁９ｍには、開口９５ｍが設けられ、この開口９５ｍに窓９６ｍが設けられている。

【０１４９】
次に、このユニット建物Ｕｍの施工方法について説明する。
このユニット建物Ｕｍの施工方法は実施例６とほぼ同じように、工場で、建物ユニット１ｍ、バルコニー取付可能な建物ユニット２ｍ、バルコニー４ｍ、連結床パネル６ｍ、屋根パネル３ｍ等を製造し、これを施工現場に運搬し、施工現場では、予め設けられている基礎９９の上に９個の建物ユニット１ｍを据え付け、この９個の建物ユニット１ｍの上に７個の建物ユニット１ｍと２個のバルコニー取付可能な建物ユニット２ｍを据え付け、この２個のバルコニー取付可能な建物ユニット２ｍに２個のバルコニー４ｍをそれぞれ接続し、この２個のバルコニー４ｍに連結床パネル６ｍを架け渡して取り付け、屋根パネル３ｍを取り付け、種々な仕上げを行うと、ユニット建物Ｕｍが完成する。

このように、２個のバルコニー４ｍを連結床パネル６ｍで連結した後に、端側のバルコニー支持梁４１ｍと軒先梁４３ｍと連結軒先梁材６３ｍの上に手摺り６９ｍを取り付ける。
すると、バルコニー４ｍが連結床パネルの分だけ広くなるし、この連結床パネル６ｍの上を通って一方のバルコニー４ｍから他方のバルコニー４ｍに移動でき、便利になる。

BACKGROUND OF THE INVENTION
The present invention relates to a connection structure for an outdoor space in which an outdoor space such as a balcony having an outdoor space support beam, an entrance porch on the second floor, and an outer corridor is connected to a building.
[0002]
[Prior art]
Conventionally, various connection structures for outdoor spaces in which an outdoor space such as a balcony having a cantilever balcony support beam is attached to a building are known.
For example, as described in Japanese Patent Laid-Open No. 7-259178 (referred to as Conventional Example 1), an auxiliary beam is provided in a building body in a state substantially orthogonal to the outer wall, and the balcony attached to the outer wall has a protruding direction. There is known a balcony connection structure in which a balcony support beam is provided toward the surface, and the auxiliary beam and the balcony support beam are connected on substantially the same straight line with a structural material provided in the vicinity of the outer wall.
[0003]
As described in the conventional example 1, when the balcony support beam and the auxiliary beam are connected on substantially the same straight line, the balcony support beam and the auxiliary beam are connected on the substantially same straight line with the structural material near the outer wall interposed therebetween. As a result, it is the same as if one beam was provided, and as a result, the bending moment acting on the structural material near the outer wall is reduced, and the balcony support beam is a cantilever beam. However, this balcony support beam can support the load of the balcony, which is a preferable structure.
[0004]
Patent No. 2610755 (referred to as Conventional Example 2) comprises a balcony unit having a balcony part opened at least in the front, a living room part partitioned from the balcony part, and a balcony unit. A building with a balcony is described in which a balcony unit is attached to the outdoor side of the balcony portion of the building unit, and the floor of the balcony unit and the floor of the balcony portion of the building unit are connected to form a floor of an expanded space.
[0005]
And although this balcony unit is not clear the connection structure connected to the building unit, it seems that it is a cantilever balcony judging from the fact that there is no pillar on the outdoor side in the drawings attached to the specification. And the Example by which this cantilever balcony protrudes and is attached to the outdoor side of the building unit is described.
In this building with a balcony, an enlarged space in which the floor of the balcony and the balcony portion of the building unit are connected to each other is formed, so that the balcony can be used widely and is a preferable structure.
[0006]
[Problems to be solved by the invention]
In ordinary cantilever balconies such as buildings with balconies described in Conventional Example 2, as described in Japanese Patent Application Laid-Open No. 6-49892, balcony floor beams protruding in the outdoor direction on the balcony (in the publication, described as arms) The balcony floor beam and the structural material such as the floor beam of the building are connected by a connecting device such as a bolt and nut.
[0007]
However, in such a connection structure, if the balcony protrudes long outside or the balcony is heavy, an excessive shear bending moment acts on the structural material such as a floor beam connected to the balcony of the building unit, and the floor beam, etc. The structural material is twisted and the outdoor side of the balcony hangs down. In the worst case, the balcony falls. Therefore, the building with a balcony described in the conventional example 2 has a problem that it can be applied only to a balcony protruding short.
[0008]
Further, in the balcony connection structure described in the conventional example 1, since the auxiliary beam connected substantially in the same straight line as the balcony support beam supports the balcony, the balcony support beam and the auxiliary beam have only one. Although it becomes like a beam and there is no problem as described above, it is necessary to provide the same number of auxiliary beams as the balcony support beam in the building body, and there is a problem that the building becomes expensive.
[0009]
Therefore, an object of the present invention is to provide a connection structure for an outdoor space that can be provided even in a heavy outdoor space that protrudes to some extent or that can reduce the number of auxiliary beams of a building body or a building unit. .

[0061]
And the balcony support beam 41b of balcony A4b-1 and the extension indoor side beam 44b of balcony B4b-2 are connected.
Then, the flooring 47b (the floor of the balcony 4b) of the balcony A4b-1 and the balcony B4b-2 is substantially the same as the flooring of the building unit 2b that can be attached to the balcony following the balcony 4b (the floor of the connection space portion Sb). It becomes a height and a floor of a continuous expansion space is formed here.
[0062]
In the unit building Ub completed in this way, as shown in FIG. 12, the balcony A4b-1 and the balcony B4b-2 are each provided with two balcony support beams 41b in the protruding direction. Since the balcony support beam 41b and the floor beam 22b of the short side of the building unit 2b that can be attached to the balcony and the floor beam 22b of the long side are connected almost on the same straight line across the column 21b, the column 21b is sandwiched between them. Thus, the balcony support beam 41b and the short-side floor beam 22b, which are connected substantially on the same straight line, and the balcony support beam 41b and the long-side floor beam 22b are each as if they were one beam.
[0063]
Therefore, even if the bending moment acting on the column 21b is reduced and the balcony support beam 41b is a cantilever beam, each of the two balcony support beams 41b provided on both balconies 4b has a balcony A4b−. 1 and the load on the balcony B4b-2 can be supported, and even if the balcony A4b-1 or the balcony B4b-2 protrudes to a certain extent in the outdoor direction or is somewhat heavy, there is no problem.
[0064]
Moreover, in this connection structure of balcony A4b-1, since there is no auxiliary beam, it becomes cheaper than a building unit with a conventional auxiliary beam that can be attached to a balcony. Also, by simply replacing the floor beam of the building unit 1b with a floor beam provided with a connection plate, a skeleton having almost the same structure as the building unit 1b can be used as the skeleton of the building unit 2b that can be attached to a balcony. It will be cheaper.
[0065]
Further, in addition to the above effects, a connection space portion Sb that follows the balcony is formed in a portion delimited by the U-shaped front outer wall 91b and sleeve wall 92b, and this connection space portion Sb and the space of the balcony 4b are continuous. Since the expansion space is formed, the formed expansion space is easy to use widely.

[0074]
Since other structures are substantially the same as those of the first embodiment, description thereof is omitted.
The construction method of the unit building Uc is almost the same as in the first embodiment. In the factory, the building unit 1c, the building unit A2c-1, the building unit B2c-2, the balcony A4c-1, the balcony B4c-2, the roof panel, etc. Is manufactured and transported to the construction site. On the construction site, the building unit 1c, the building unit A2c-1, and the building unit B2c-2 are installed on the foundation, and the building unit A2c-1 and the building are installed. When the balcony A4c-1 and the balcony B4c-2 are connected to the unit B2c-2, the roof panel is attached, and various finishing is performed, the unit building Uc is completed.
[0075]
The connection method and operation of balcony A4c-1 and balcony B4c-2 at this time will be described.
In the same manner as in the first embodiment, the connection plate 48c attached to the indoor side end surfaces of the two balcony support beams 41c of the balcony A4c-1 and the connection plate of the long side floor beam 22c are opposed to each other with the column 21c interposed therebetween. Then, a bolt is passed through the connection plate 48c of the balcony support beam 41c from the connection plate of the long-side floor beam 22c, and a nut is screwed into the bolt to attach the balcony A4c-1 to the building unit A2c-1.
[0076]

And the balcony support beam 41c of balcony A4c-1 and the balcony support beam 41c of balcony B4c-2 are connected.
Then, as shown in FIG. 17, the flooring 47c (the floor of the balcony 4c) of the balcony A4c-1 and the balcony B4c-2, and the flooring 26c (the floor of the connection space portion Sc) of the corridor 96c following the balcony 4c Are almost the same height, and a continuous expanded floor is formed.
[0078]
In the unit building Uc thus completed, as shown in FIG. 15, the balcony A4c-1 is provided with two balcony support beams 41c in the protruding direction, and the two balcony support beams 41c and The two long-side floor beams 22c are connected to each other on almost the same straight line with the columns 21c sandwiched between them, although they are slightly different in height, but are connected on substantially the same straight line with the columns 21c interposed therebetween. The balcony support beam 41c and the long side floor beam 22c are like a single beam.
[0079]
Accordingly, the bending moment acting on the column 21c is reduced, and even when the balcony support beam 41c is a cantilever beam, the load of the balcony A4c-1 can be supported by the two balcony support beams 41c. Even if A4c-1 protrudes to a certain extent in the outdoor direction or is somewhat heavy, there is no problem.
[0080]
Further, the balcony B4c-2 is provided with two balcony support beams 41c in the protruding direction of the balcony B4c-2, and one of the balcony support beams 41c and one long side floor beam 22c are provided. And the other balcony support beam 41c and the auxiliary beam 5c are connected to each other on substantially the same straight line with the short-side floor beam 22c interposed therebetween. The balcony support beam 41c and the long side floor beam 22c and the auxiliary beam 5c, which are connected on the same straight line with the floor beam 22c interposed therebetween, are as if they were one beam.
[0081]
Accordingly, the bending moment acting on the column 21c and the floor beam 5c is reduced, and even when the balcony support beam 41c is a cantilever beam, the load of the balcony B4c-2 is supported by the two balcony support beams 41c. There is no problem even if the balcony B4c-2 protrudes in the outdoor direction to some extent or is somewhat heavy.
[0082]
Further, in the connection structure of the balcony A4c-1 and the balcony B4c-2, only one auxiliary beam 5c is used. Therefore, in order to connect to the conventional four balcony support beams 41c, four auxiliary beams are used. It is cheaper than a building unit that can be attached to a balcony.
Furthermore, a connecting space portion Sc that follows the balcony is formed in a portion delimited by the L-shaped front outer wall 91c and the sleeve wall 92c, and a continuous enlarged space is formed by the connecting space portion Sc and the space of the balcony 4c. Thus, the formed expansion space is wide and easy to use.
[0083]
(Example 5)
