Description

【０００１】
【発明の属する技術分野】
この発明は、箱形状の建物ユニットの複数からなるユニット建物に関する。
【０００２】
【従来の技術】
従来、壁式工法による箱形状の建物ユニットからなるユニット建物が、特開昭６０−３３９５８号公報に記載されているように、知られている。これは、床パネルに壁パネルを立設してなる箱形状の建物ユニットを用いている。この建物ユニットの複数と、各建物ユニットの上部に接合される屋根ユニットとを、建築現場で組み立て１戸の建物に構築するものである。この建物ユニットは、工場で予め生産される。
【０００３】
ところで、木質の壁式工法による建物にあっても、３階建てが許可されるなど、建物に高強度が要求されるようになってきた。ところが、上記特開昭６０−３３９５８号公報に記載のユニット建物にあっては、建物の構造耐力上の主要な壁（耐力壁という）は、すべて、それぞれの建物ユニットの床パネルの側縁に限定されて立設されていた。
【０００４】
また、法規制などにより、耐力壁はその高さの１／３以上の幅を有しなければならない。壁の高さは、居室の高さにおける良好な居住性から２４００ｍｍ以上必要なので、耐力壁の幅は８００ｍｍ以上必要となる。
【０００５】
【発明が解決しようとする課題】
従来の特開昭６０−３３９５８号公報等に記載のユニット建物では、耐力壁は各建物ユニット単位で設けられており、ユニットに股がって耐力壁を構成するものはなかった。このため、隣接する建物ユニット相互の接合部を強固に接合しないと、その強度が低下するなどの問題があった。
【０００６】
また、建物ユニットは工場から建築現場へ輸送する必要上、道路交通法の制限から、その建物ユニットの短辺側寸法は２５００ｍｍ未満とするのが有利である。このため、建物ユニットの短辺側の内８００ｍｍ以上を耐力壁で占有されてしまうと、残りは１７００ｍｍ以下となり、開口部を設ける場合、その位置や大きさに制約があった。
【０００７】
例えば、図９のイ）に示すように、二つの建物ユニット１、１を、その長辺側同士を並べた場合、両建物ユニット１、１の短辺側の二辺（ａ＋ｂ）は５０００ｍｍの長さになる。この短辺側の二辺（ａ＋ｂ）の範囲に、長さ（幅）８００ｍｍの耐力壁が一つ必要となる場合、耐力壁を設けた側の建物ユニット１の短辺（ａ）の範囲では、残りが１７００ｍｍ以下となってしまい、１８００ｍｍ幅（いわゆる一間間口）の開口部が取れない。１８００ｍｍ幅以上の開口部は、他方の建物ユニット１の短辺側（ｂ辺側）にしか取れなかった。
【０００８】
あるいは、図９のロ）に示すように、三つの建物ユニット１、２、１を、その長辺側同士を並べた場合、それらの短辺側の三辺（ａ＋ｂ＋ｃ）は７５００ｍｍの長さになる。この範囲に８００ｍｍ長（幅）の耐力壁が二つ必要となる場合、やはり１８００ｍｍ幅（一間間口）以上の開口部は一つしか取れなかった。
【０００９】
この発明は、上述の従来技術の問題点を解消し、建物の構造強度が大きく、また、耐力壁パネルを立設しても、開口の位置や大きさに制約が少なく、間取りプランの自由度も上がるユニット建物を提供することを目的とする。

【００２０】
【作用】
請求項１記載のユニット建物は、二つの建物ユニットの床パネルに股がって、幅８００ｍｍ以上の耐力壁パネルが立設され、耐力壁パネルの各床パネルへの接合長さ（幅）はそれぞれ７００ｍｍ未満とされているから、二つの建物ユニット間の接合強度が向上するとともに、居室の壁高さに対して必要な耐力壁が確保される。しかも、例えば、建物ユニットの短辺側の長さが２５００ｍｍの場合、それぞれの建物ユニットに幅１８００ｍｍ以上の開口部を取ることが可能になり、建物ユニットの二つを隣接配置して合計５０００ｍｍの長さの間に、幅１８００ｍｍ以上の開口部を二つ設けることができる。
【００２１】
請求項２記載のユニット建物は、三つの建物ユニットが長辺側同士で並べられ、相隣り合う床パネルに股がって、幅８００ｍｍ以上の耐力壁パネルが二つ立設され、耐力壁パネルの各床パネルへの接合長さ（幅）はそれぞれ７００ｍｍ未満とされているから、各建物ユニット間の接合強度が向上するとともに、居室の壁高さに対して必要な耐力壁が確保される。しかも、例えば、建物ユニットの短辺側の長さが２５００ｍｍの場合、三つを隣接配置して合計７５００ｍｍの長さの間に、幅１８００ｍｍ以上の開口部を二つ設けることができる。
【００２２】
請求項３記載のユニット建物は、隣り合う二つの建物ユニットの各々の床パネルに、幅７００ｍｍ未満の壁枠組が立設され、壁枠組の合計長さ（幅）は８００ｍｍ以上とされ、二つの壁枠組に面材が渡貼りされて耐力壁パネルとなされているから、各建物ユニット間の接合強度が向上するとともに、居室の壁高さに対して必要な耐力壁が確保される。しかも、例えば、建物ユニットの短辺側の長さが２５００ｍｍの場合、それぞれの建物ユニットに幅１８００ｍｍ以上の開口部を取ることが可能になり、建物ユニットの二つを隣接配置して合計５０００ｍｍの長さの間に、幅１８００ｍｍ以上の開口部を二つ設けることができる。また、工場でそれぞれの建物ユニットに壁枠組を立設することが可能になり、建築現場ではこれに面材を渡貼りするのみできるから、建築現場の施工工数が少なくて済み、壁内配線なども床とつないだ状態で、工場で取り付けできる。
【００２３】
請求項４記載のユニット建物は、隣り合う二つの建物ユニットの各々の床パネルに、幅７００ｍｍ未満の耐力壁パネルが立設され、耐力壁パネルの合計長さ（幅）は８００ｍｍ以上とされ、二つの耐力壁パネルの縦枠同士がスペーサーを介して接合されているから、隣り合う耐力壁パネルが隙間なく一体に接合されて一つの耐力壁パネルになり、各建物ユニット間の接合強度が向上するとともに、居室の壁高さに対して必要な耐力壁が確保される。しかも、例えば、建物ユニットの短辺側の長さが２５００ｍｍの場合、それぞれの建物ユニットに幅１８００ｍｍ以上の開口部を取ることが可能になり、建物ユニットの二つを隣接配置して合計５０００ｍｍの長さの間に、幅１８００ｍｍ以上の開口部を二つ設けることができる。また、それぞれの建物ユニットに耐力壁パネルを工場で取り付け可能になり、工場付けされた二つの耐力壁パネルの縦枠の間に、建築現場でスペーサーを介して接合して耐力壁となせばよいから、建築現場の施工工数が少なくて済み、壁内配線を床内配線とつないだ状態で工場で取り付けできる。更に、耐力壁パネル間に内面材を渡貼りにすればさらに耐力壁の強度が上がる。
【００２４】
請求項５記載のユニット建物は、隣り合う二つの建物ユニットの床パネルに股がって該二つの床パネルを合わせた幅と略等しい幅の壁パネルが立設接合されているから、隣り合う二つの建物ユニット間に壁パネルが的確に接合されて両建物ユニットが一体化されて、簡単な構造で両建物ユニット間の接合強度が向上し、ユニット建物全体の強度が優れたものになる。
【００２５】
また、隣り合う二つの建物ユニットの各々の床パネルに股がって壁パネルが立設され、該壁パネルには上記床パネルに股がる領域に幅８００ｍｍ以上の耐力壁が一体化されているから、ユニット建物の強度が上がる。また、プラン上の自由度が上がる。さらに、壁パネル全体の仕上げ（塗装、クロス貼り、建具取付け）が工場で行うことができ、内外装が一体的になされ美麗に仕上がる。また、建築現場の施工工数も少なくて済む。
【００２６】
請求項６記載のユニット建物は、上記隣り合う二つ建物ユニットの床パネルに股がって鋼製接合プレートが貼り渡されているから、上記請求項１〜５の作用に加えて、隣り合う床パネル同士の変位、特にせん断変位が防止されて、両床パネルに股る耐力壁パネル等の耐力が十分に発揮できるものとなり、建物ユニット間の接合強度が向上するとともに、ユニット建物の強度がより優れたものになる。
【００２７】
請求項７記載のユニット建物は、上記耐力壁パネル以外の開口部付き壁パネルは工場で床パネルと接合されて建物ユニットを構成しているから、この開口部付き壁パネルは立設された状態になるので、建築現場への輸送中、開口部に取り付けた建具などに特別な保護養生が不要である。また、建築現場での施工工数も少なくて済む。

【００３０】
コの字壁状の建物ユニット１は、図２の（イ）に示すように、床パネル１１の隣り合う二つの側縁に耐力壁パネル１２、１３が立設されている。耐力壁パネル１２に相対向する床パネル１１の側縁には開口部１５付きの壁パネル１４が立設されている。壁パネル１４は、耐力壁パネル１２に比べて、その側部１６の部分がない状態になっていて幅が狭くなされている。
【００３１】
二の字壁状の建物ユニット２は、図２の（ロ）に示すように、床パネル２１の相対向する２つの側縁にそれぞれに耐力壁パネル２２と、開口部２４付きの壁パネル２３が立設されている。壁パネル２３は、耐力壁パネル２２よりも幅が狭くなされ、その両側部２５、２５の部分が無い状態になっている。
【００３２】
（実施例１）
図３の（イ）は建物ユニット１、１をその長辺側同士を並べて隣接配置したユニット建物の平面図であり、耐力壁１２、１２が突き合わせられて直線状に配置されており、これらに相対向して開口部１５付き壁パネル１４、１４が立設されている。
【００３３】
建物ユニット１の短辺側の幅（長さ）は２５００ｍｍであり、開口部１５付き壁パネル１４の幅は２１００ｍｍであり、４００ｍｍ建物ユニットの幅より短くなされている。しかし、開口部１５の幅は１８００ｍｍあり、いわゆる一間間口の開口を有している。耐力壁１２、１２、壁パネル１４、１４の高さは２４００ｍｍになっている。
【００３４】
そして、図３の（ロ）に示すように、二つの床パネル１１、１１に股って幅８００ｍｍの耐力壁パネル３が立設される。耐力壁パネル３は、ツーバイフォー材からなる壁枠組３２に硬質木片セメント板からなる面材３１が釘打ち固定されて耐力壁を構成している。二つの床パネル１１、１１の接合長さ（幅）はそれぞれ４００ｍｍであり、合計８００ｍｍあるので、耐力壁パネル３を立設できる。耐力壁パネル３の枠組３２の下端と床パネル１１、１１とは釘打ちされて緊結され、面材３１の下端部も床パネル１１、１１に釘打ちされて渡貼りされている。さらに、両側の開口部１５付き壁パネル１４、１４の上端部と耐力壁パネル３とが頭つなぎ材（鋼製接合プレート）４、４で連結されている。立設状態の耐力壁パネル３の高さは２４００ｍｍになっている。
【００３５】
このユニット建物は、二つの建物ユニット１、１の床パネル１１、１１に股がって、幅８００ｍｍの耐力壁パネル３が立設され、耐力壁パネル３の各床パネル１１、１１への接合長さ（幅）はそれぞれ４００ｍｍとされて上記のように緊結接合されているから、二つの建物ユニット１、１間の接合強度が向上するとともに、居室の壁高さ（２４００ｍｍ）に対して必要な耐力壁が確保される。しかも、二つの建物ユニット１、１の長辺側を並べて、８００ｍｍ幅の耐力壁を設けても、１８００ｍｍ幅以上の開口部を二箇所取ることができる。
【００３６】
（実施例２）
図４の（イ）は建物ユニット１、２、１を隣接配置したユニット建物の平面図であり、耐力壁１２、２２、１２が直線状に配置され、これらに相対向して開口部１５付き壁パネル１４、開口部２４付き壁パネル２３、開口部１５付き壁パネル１４が立設されている。
【００３７】
建物ユニット１の幅（長さ）、開口部１５付き壁パネル１４の幅、及び開口部１５の幅、及びこれらの高さは実施例１と同様である。また、建物ユニット２の幅（長さ）は２５００ｍｍであり、開口部２４付き壁パネル２３の幅は１７００ｍｍであり、両側をそれぞれ４００ｍｍづつ合計８００ｍｍ建物ユニットの幅より短くなされている。そのため開口部２４の幅は１３５０ｍｍであり、１間間口よりはやや狭い開口を有している。
【００３８】
そして、二つの床パネル１１（接合長さ４００ｍｍ）と床パネル２１（接合長さ４００ｍｍ）、及び、床パネル２１（接合長さ４００ｍｍ）と床パネル１１（接合長さ４００ｍｍ）に、それぞれ股がって、実施例１と同様の幅８００ｍｍの耐力壁パネル３、３を立設している。図４の（ロ）に示すように、耐力壁パネル３が床パネル１１、２１上に載せられる。そして、その枠組３２の下端と床パネル１１、２１とは釘打ちされて緊結され、面材３１の下端部も床パネル１１、２１に釘打ちされて渡貼りされている。さらに、両側の開口部２４付き壁パネル２３、及び開口部１５付き壁パネル１４の上端部とに耐力壁パネル３の上端部がそれぞれ頭つなぎ材（鋼製接合プレート）４、４で連結されている。
【００３９】
このユニット建物は、三つの建物ユニット１、２、１が長辺側同士で並べられ、相隣り合う床パネル１１、２１に股がって、幅８００ｍｍの耐力壁パネル３が二つ立設され、耐力壁パネル３の各床パネル１１、２１への接合長さ（幅）はそれぞれ４００ｍｍとされて上記のように緊結接合されているから、三つの建物ユニット１、２、１間の接合強度が向上するとともに、居室の壁高さ（２４００ｍｍ）に対して必要な耐力壁が確保される。しかも、建物ユニット１、２、１の短辺側の長さが２５００ｍｍであるが、三つを隣接配置して合計７５００ｍｍの長さの間に、幅１８００ｍｍの開口部１５、１５を二つと、幅１３５０ｍｍの開口２４を一つ設けることができる。
【００４０】
（実施例３）
図５の（イ）は建物ユニット１、２、１の長辺側を隣接配置したユニット建物の平面図であり、耐力壁１２、２２、１２に相対向して開口部１５付き壁パネル１４、開口部２４付き壁パネル２３、開口部１５付き壁パネル１４が立設されている。また、耐力壁パネル３Ａ用のツーバイフォー材からなる壁枠組３２Ａが、建物ユニット１、１にそれぞれ一箇所、建物ユニット２に二箇所、予め工場で立設されている。この壁枠組３２Ａは、隣接する壁パネル１４、２３に釘と鋼製接合プレートにより緊結されている。
【００４１】
建物ユニット１、２の幅（長さ）、開口部１５付き壁パネル１４の幅、及び開口部２４付き壁パネル２３の幅、開口部１５の幅、及び２４の幅、及びこれらの高さは実施例２と同様である。また、耐力壁パネル３Ａ用の壁枠組３２Ａの幅は４００ｍｍであり、壁枠組３２Ａを二つ合わせて８００ｍｍ幅となし、渡貼り面材３１Ａを貼設して耐力壁パネル３Ａとする。
【００４２】
そして、二つの床パネル１１、２１及び２１、１１にそれぞれ立設された４００ｍｍ幅の枠組３２Ａ、３２Ａに、屋外側より、図５の（ロ）に示すように、硬質木片セメント板からなる渡し貼り用の面材３１Ａが釘打ちされて貼設される。さらに、壁枠組３２Ａ、３２Ａの上端部に股って頭つなぎ材（鋼製接合プレート）４で連結されている。
【００４３】
このユニット建物は、隣り合う三つの建物ユニット１、２、１の各々の床パネル１１、２１、１１に、幅４００ｍｍの壁枠組３２Ａが立設され、壁枠組３２Ａ、３２Ａの合計長さ（幅）は８００ｍｍとされ、二つの壁枠組３２Ａ、３２Ａに面材３１Ａが渡貼りされてしかも頭つなぎ材で連結されて耐力壁パネル３Ａとなされているから、各建物ユニット１、２間の接合強度が向上するとともに、居室の壁高さ（２４００ｍｍ）に対して必要な耐力壁が確保される。しかも、建物ユニット１、２の短辺側の長さが２５００ｍｍであるが、両側の建物ユニット１、１に幅１８００ｍｍの開口部１５、１５を取れる。すなわち、三つの建物ユニット１、２、１を並べて、８００ｍｍ幅の耐力壁が二つ設けられても、１８００ｍｍ幅の開口部を二箇所設けることができる。
【００４４】
また、工場でそれぞれの建物ユニット１、２に壁枠組３２Ａを立設することができ、建築現場ではこれに面材３１Ａを渡貼りするのみであるから、建築現場の施工工数が少なくて済む。更に、壁内配線なども、床パネルの配線とつないだ状態で、工場で取り付けできる。
【００４５】
（実施例４）
図６は建物ユニット１、１を隣接配置したユニット建物の斜視図であり、開口部１５付き壁パネル１４、１４の間に耐力壁パネル３Ｂ用の壁枠組３２Ｂ、３２Ｂが予め工場で立設され、また、外壁面材３１Ｂ、３１Ｂも予め貼設されている。
【００４６】
建物ユニット１の幅（長さ）、開口部１５付き壁パネル１４の幅、開口部１５の幅は実施例１と同様である。また、耐力壁パネル３Ｂ用の壁枠組３２Ｂの幅は４００ｍｍであり。壁枠組３２Ｂに外壁面材３１Ｂが貼られて耐力壁パネル３０Ｂになっている。耐力壁パネル３０Ｂを二つ合わせて８００ｍｍ幅以上となし、耐力壁パネル３Ｂとする。すなわち、二つの床パネル１１、１１にそれぞれ立設された４００ｍｍ幅の壁枠組３２Ｂ、３２Ｂに、屋内側より、構造用合板からなるスペーサー５を介して縦枠３２１Ｂ、３２１Ｂを貫通するボルト６、６により連結されて一体の耐力壁パネル３Ｂになされる。その後、耐力壁パネル３Ｂに内壁面材（不図示）を渡し貼りして、内装仕上げをする。耐力壁パネル３Ｂなどの上部は頭つなぎ材（鋼製接合プレート）で連結してもよい。そうすると、更に強度が向上する。
【００４７】
このユニット建物は、隣り合う二つの建物ユニット１、１の各々の床パネル１１、１１に、幅４００ｍｍの耐力壁パネル３０Ｂ、３０Ｂが立設され、耐力壁パネル３Ｂの合計長さ（幅）は８００ｍｍ以上とされ、二つの耐力壁パネル３０Ｂ、３０Ｂの縦枠３２１Ｂ、３２１Ｂ同士がスペーサー５を介して接合されているから、隣り合う耐力壁パネル３０Ｂ、３０Ｂが隙間なく一体に接合されて一つの耐力壁パネル３Ｂになり、各建物ユニット１、１間の接合強度が向上するとともに、居室の壁高さ（２４００ｍｍ）に対して必要な耐力壁が確保される。しかも、建物ユニット１の短辺側の長さが２５００ｍｍであるが、それぞれの建物ユニット１、１に幅１８００ｍｍ以上の開口部１５、１５を取ることが可能になる。したがって、建物ユニットの二つを隣接配置した合計５０００ｍｍの長さ（幅）の間に、幅１８００ｍｍ以上の開口部１５、１５を二つ設けることができる。また、それぞれの建物ユニット１、１に耐力壁パネル３０Ｂ、３０Ｂを工場で取り付け可能になり、工場付けされた二つの耐力壁パネル３０Ｂ、３０Ｂの縦枠の間に、建築現場でスペーサー５を介して接合して耐力壁パネル３Ｂとなせばよいから、建築現場の施工工数が少なくて済む。更に、壁内配線を床内配線とつないだ状態で工場で取り付けできる。耐力壁パネル３０Ｂ、３０Ｂ間に内面材を渡貼りしているので、更に耐力壁パネル３Ｂの強度が上がっている。
【００４８】
上記実施例１〜４のユニット建物は、上記耐力壁パネル以外の開口部付き壁パネル１４、２３が工場で床パネル１１、２１と接合されて建物ユニット１、２を構成しているから、この開口部付き壁パネル１４、２３は立設された状態になるので、建築現場への輸送中、開口部１５、２４に取り付けた建具などに特別な保護養生が不要である。また、建築現場での施工工数も少なくて済む。
【００４９】
（実施例５）
図７の（イ）は建物ユニット１、１を隣接配置したユニット建物の斜視図であり、連続する建物ユニット１、１の短辺側の幅２５００ｍｍ×２＝５０００ｍｍ幅の開口に、全長（幅）５０００ｍｍの壁パネル１０Ｃを建築現場にて立設している。壁パネル１０Ｃは、１８００ｍｍの開口部１５Ｃを２箇所有し、その間に８００ｍｍ以上の耐力壁３Ｃを有し一体になされている。
【００５０】
図７の（ロ）の平面図に示すように、隣り合う二つの建物ユニット１、１の床パネル１１、１１に股がって該二つの床パネル１１、１１を合わせた幅と等しい幅の壁パネル１０Ｃが立設接合されている。壁パネル１０Ｃは建物ユニット１、１の開口の床パネル１１、１１や壁パネル１３、１３に釘打ち、ボルトなどにより一体に接合固定されている。
【００５１】

Conventionally, a unit building composed of a box-shaped building unit by a wall-type construction method is known as described in JP-A-60-33958. This uses a box-shaped building unit in which a wall panel is erected on a floor panel. A plurality of the building units and a roof unit joined to the upper part of each building unit are assembled into a single building at the construction site. This building unit is produced in advance at the factory.
[0003]
By the way, even in buildings using a wooden wall construction method, high strength has been required for buildings, for example, three-story buildings are permitted. However, in the unit building described in Japanese Patent Laid-Open No. 60-33958, all the main walls (referred to as load-bearing walls) on the structural strength of the building are located on the side edges of the floor panel of each building unit. It was limited and erected.
[0004]
In addition, due to laws and regulations, the bearing wall must have a width of 1/3 or more of its height. Since the height of the wall is required to be 2400 mm or more from the good comfortability at the height of the living room, the width of the bearing wall is required to be 800 mm or more.

Become length. When one bearing wall having a length (width) of 800 mm is required in the range of the two sides (a + b) on the short side, in the range of the short side (a) of the building unit 1 on the side where the bearing wall is provided, The remainder becomes 1700 mm or less, and an opening portion having a width of 1800 mm (a so-called one frontage) cannot be taken. An opening having a width of 1800 mm or more could be taken only on the short side (b side) of the other building unit 1.
[0008]
Alternatively, as shown in FIG. 9B), when the long sides of three building units 1, 2, and 1 are arranged side by side, the three sides (a + b + c) on the short sides are 7500 mm long. Become. When two 800 mm long (width) bearing walls were required in this range, only one opening having a width of 1800 mm (one frontage) or more could be taken.
[0009]
