Description

【０００１】
【発明の属する技術分野】
本発明は、建物ユニットの接合構造、接合方法に関する。
【０００２】
【従来の技術】
従来、住宅等のユニット建物は、複数の建物ユニットを接続して構築されているが、この建物ユニットは、床パネルの周囲に壁パネルが立設された構造となっている（特公平５─３８１０２号公報参照）。
【０００３】
上記のような建物ユニット同士の水平方向の接合構造は、壁パネル上端同士を接合する板金製接続具と、床パネルに渡し張りする継なぎ面材による接合構造となっている。
【０００４】
【発明が解決しようとする課題】
上記のような接合構造の建物ユニットの場合、壁パネルで形成される部屋の大きさ、開口の有無、大小により、壁パネルの形成される壁面の数量により、板金製接続具の締結本数が制限され、板金製接続具と継なぎ面材だけでは均一なる接合強度を確保しずらいといった問題がある。また、３階建等においては、建物ユニット間の接合強度が不足するといった問題もある。
【０００５】
本発明は、上記のこのような問題点に着目してなされたものであり、その目的とするところは、これらの問題点を解消し、隣接する建物ユニット同士を強固に接合できる建物ユニットの接合構造を提供するものである。
【０００６】
【課題を解決するための手段】

【０００７】
請求項２記載の本発明は、床パネルの外縁部に壁パネルが立設されてなる建物ユニットを複数突き合わせて配置し、隣接する床パネル同志を接合する建物ユニットの接合方法において、取付け片と、この取付け片に垂設され、締結ボルトを挿通可能な挿通孔を備えた係止部とからなる締結金具の取付け片をそれぞれの建物ユニットの床パネルの床構造材の端部にあらかじめ固着し、締結ボルトを、あらかじめ一方の建物ユニットの床パネル締結孔から挿入し、締結金具の係止部の挿通孔に挿通させて床パネル内に没入させておき、その後、建物ユニットを突き合わせて配置し、その後上記締結ボルトを引き出して他方の建物ユニットの床パネルにまで股がらせ、それぞれの床パネルに固着された締結金具の係止部の挿通孔から突出させ、螺入されたナットで締結することを特徴とする。
【０００８】
請求項３記載の本発明は、建物ユニットの床パネルの隅部で、直交する床構造材のそれぞれと隣接する建物ユニットの床パネルの床構造材とを接合した床パネルの外縁部に壁パネルが立設されてなる建物ユニットの接合構造であって、直交する床構造材の床パネル内側面に取り付けられた板状片が略直角に交わってなる締結金具が、それぞれの板状片に挿通孔を備え、締結ボルトを挿通孔より挿通して、隣接する建物ユニットの床パネルのそれぞれの床構造材に取り付けられた取付け片と、この取付け片に垂設され、締結ボルトを挿通可能な挿通孔を備えた係止部とからなる締結金具の係止部の挿通孔から突出され、螺入されたナットで締結されていることを特徴とする。
【０００９】
請求項４記載の本発明は、床パネルの外縁部に壁パネルが立設されてなる建物ユニットの床構造材と隣接する屋根用建物ユニットの屋根構造材を接合してなる建物ユニットの接合構造であって、取付け片と、この取付け片に垂設され、締結ボルトを挿通可能な挿通孔を備えた締結ボルト係止部からなる締結金具の取付け片がそれぞれの構造材に固着され、隣接するそれぞれの構造材に設けられた挿通孔より締結ボルトを挿通して、締結ボルトの両端が係止部の挿通孔から突出され、螺入されたナットで締結されていることより床構造材と隣接する屋根構造材が締結されていることを特徴とする。
【００１０】
【作用】
請求項１記載の本発明の建物ユニットの接合構造は、締結ボルトの一端が、一側床パネルの締結金具の挿通孔に挿入係止され、他端が他側床パネルの締結金具の挿通孔から突出され、螺入されたナットで締結されているので、床パネル同志が緊密に締結され、建物ユニットの接合強度を向上させることができる。これによって３階を有するユニット建物においても、その接合強度の向上により、強固な建物を構築できる。
【００１１】
そして、取付け片が座金付きボルトで締結されているので、ボルト頭の突出が少ないため、他の部材との干渉が少なく設計が簡易である。
【００１２】
請求項２記載の建物ユニットの接合方法においては、締結金具が、あらかじめ床パネルに固着されているので、現場の組み立て手間が軽減され、施工コストを削減することができる。
また、締結ボルトを、あらかじめ一方の建物ユニットの床パネル締結孔から挿入して床パネル内に没入させておき、その後、建物ユニットを突き合わせて配置し、その後上記締結ボルトを引き出して他方の建物ユニットの床パネルにまで股がらせ、それぞれの床パネルに固着された締結金具に締結するので、床根太と床根太のピッチが締結ボルトの長さより小さい時でも床パネル同士の締結作業を容易に行うことが出来る。
【００１３】
請求項３記載の建物ユニットの接合構造において、直交する床構造材の床パネル内側面に取り付けられた板状片が略直角に交わってなる締結金具が、それぞれの板状片に挿通孔を備え、締結ボルトを挿通孔より挿通して、隣接する建物ユニットの床パネルのそれぞれの床構造材に取り付けられた締結金具と締結ボルトで締結されているので、締結ボルト同士が干渉することなく隣接する構造材同士を接合することができる。
【００１４】
請求項４記載の建物ユニットの接合構造において、構造材に固定できる取付け片と締結ボルト係止部からなる締結金具が、隣接するそれぞれの構造材に設けられた挿通孔より締結ボルトを挿通して、締結ボルトの両端を係止部の挿通孔よりそれぞれ挿入して床構造材と隣接する屋根構造材が締結されているので、床構造材と隣接する屋根構造材の締結において、構造強度を確保した接合構造とすることができる。
【００１５】

以下、本発明の実施の形態を図面を参照して説明する。

【００１７】
図１において、本実施例の建物ユニットの接合構造は、床パネル１の外縁部に壁パネル２が立設されてなる建物ユニットが複数突き合わせて配置し、隣接する床パネル１同士を接合してなるものである。なお、上記建物ユニットを複数突き合わせて配置することにより、建物ユニットが構築される。
図２において、上記床パネル１の外縁部は床構造材としての床根太１１ａ、１１ｂで四方形に枠組みされ、互いに隣接する床パネル１、１の向かい合って並列する床根太１１ｂ、１１ｂの端部に設けられた締結孔３６を貫通して締結ボルト３３が取り付けられている。前記向かい合って並列するそれぞれの床根太１１ｂ、１１ｂの端部と直交する別の床根太１１ａ、１１ａのそれぞれに、締結ボルト３３を挿通可能な挿通孔３１を備えた締結金具３が固着されている。
【００１８】
上記床パネル１の締結に使用される締結金具３は、あらかじめ工場等で製造される建物ユニットの床パネル１に固着されている。
図３において、締結金具３は、締結ボルト３３を係止する係止部３４と、上記別の床根太１１ａに取り付けられる取付け片３５とからなり、締結金具３の取付け片３５は床根太１１ａの側面に座金付きボルト４で固着される。
図４において、座金付きボルト４は、締結金具３の取付け片３５を床根太１１ａに固定する際に床根太挿通孔より挿入し取付け片３５側とナット４１で締結する。その際座金付きボルト４には予め座金４ａが固着されているので、床根太１１ｂとの接触面が広くとれ、床根太１１ｂとの固定強度が確保され、また座金の取付け手間が省け取付け作業が容易となる。また、床根太１１ａに切欠きを設けて座金４ａを埋込んでいるのでボルト頭の突出がない。
【００１９】
また、締結金具３のボルト係止部３４は、取付け片３５に垂設されていて、その両側が補強板で補強されたものとなっている。
締結ボルト３３の一端は、一側床パネルの締結金具３の挿通孔３１に挿入係止され、他端は他側床パネル１の締結金具３の挿通孔３１から突出され、螺入されたナット３７で締結されている。
【００２０】
上述のように、本実施例の建物ユニットの接合構造は、
締結ボルト３３の一端が、一側床パネル１の締結金具３の挿通孔３１に挿入係止され、他端が他側床パネル１の締結金具３の挿通孔３１から突出され、螺入されたナット３７で締結されているので、床パネル１、１同士が緊密に締結され、建物ユニットの接合強度を向上させることができる。
これによって３階を有するユニット建物においても、その接合強度の向上により、強固な建物を構築できる。
【００２１】
次に、上記接合構造になされた建物ユニットの接合方法を図５、図６に基づいて説明する。
まず、図５のように、締結金具３は予め床パネル１に固着されている。そして締結ボルト３３を、あらかじめ一方の建物ユニットの床パネル１の締結孔３６から挿入して床パネル１内に没入させておく、その際、締結ボルト３３は床根太１１ｂより床パネルの外に出ない様に止める。
【００２２】
その後、図６のように、建物ユニットを突き合わせて配置し、そして上記既に据え付けられた床パネル１の方の締結金具３に係止されている、締結ボルト３３を引き出して他方の建物ユニットの床パネル１の締結孔３６から挿入する。
そして、両方の床パネル同士に固着されている締結金具３に、締結ボルト３３を股がして掛け渡し、締結ボルト３３で締結金具３同士を締結する。
床パネル１と床パネル１とはスペーサー４０で位置決めされ、締結ボルト３３で締結金具３同士にしっかりと締結される。
上記のように、締結ボルト３３を、あらかじめ一方の建物ユニットの床パネル１の締結孔３６から挿入して床パネル内に没入させておくことにより、床根太１１ｃ、１１ｂのピッチが締結ボルト３３の長さより小さい時でも、現場の締結作業が容易に行うことができる。
【００２３】
図７は、請求項５記載の構造材同士が入隅を形成する接合構造を示している。本実施例では、構造材としては床根太で構成される床パネルについて説明する。図９に示す様に、隣接する床パネルがＡ部のように入隅を形成している。
入隅の中央の床パネル１０ａは、直交する床根太１５ａ、１５ｂで形成されている。そして、直交する床根太１５ａ、１５ｂのそれぞれと隣接する他の床パネル２、３とで入隅が形成されている。即ち、入隅を形成する中央の床パネル１０ａと隣接する他の２個の床パネル１０ｂ、１０ｃよりなる建物ユニットの接合構造である。
入隅を形成する中央の床パネル１０ａの直交する床構造材としての床根太１５ａ、１５ｂの外側面に、それぞれ隣接している他の２個の床パネル１０ｂ、１０ｃの床根太がそれぞれ締結される。
詳しくは、入隅を形成する中央の床パネル１０ａの直交する床根太１５ａ、１５ｂの内側面に略直角に折れ曲がった板状片２０からなる締結金具２０ａが取り付けられる。そして、それぞれの板状片２０には締結ボルト２２を挿入できる挿通孔２１ａを備えている。
【００２４】
図８の様に、締結金具２０ａは略直角に折れ曲がった板状片２０からなり、それぞれの板状片２０には床根太の内側面に固定できる挿通孔２１ｂが設けられている。挿通孔２１ｂは長孔を形成して位置調整可能になっている。
一方、中央の床パネル１０ａに隣接するそれぞれの床パネル１０ｂ、１０ｃにも締結金具３がもうけられている。そして、隣接する床構造材としての床根太１５ｃ、１５ｅには締結ボルト２２、２２を挿入できる挿通孔３０ａ、３０ｂ、３０ｃ、３０ｄが穿孔されている。そして、締結金具３は隣接する床根太１５ｃ、１５ｅに直交する床根太１５ｄ、１５ｆの内側面にそれぞれ取り付けられている。
【００２５】
入隅部の床パネル１０ａ、１０ｂ、１０ｃの接合要領は、先ず、床パネル１０ａ、１０ｂ、１０ｃにそれぞれ締結金具２０ａ、３を床根太内側面に固定ボルト４で固定しておく、次に入隅部の中央の床パネル１０ａに取り付けられた締結金具２０ａより、挿通孔２１ａ、３０ａ、３０ｂに締結ボルト２２を挿通する。同様に締結ボルト２２を挿通孔２１ａ、３０ｃ、３０ｄより挿通する。そして、締結ボルト２２は隣接する他の床パネル１０ｂ、１０ｃの締結金具３、３の係止部の挿通孔３１より挿入されて締結される。
以上の様に、入隅部の床パネル１０ａ、１０ｂ、１０ｃの接合において、締結金具２０ａが略直角に折れ曲がった板状片２０からなるので、締結ボルト２２同士がお互いに干渉することなく締結することができる。
【００２６】
図１０は、請求項６記載の床構造材と屋根構造材とを締結する接合構造を示している。実施例は建物ユニット４７を組み立て３階のユニット建物を構成している。
３階の部分は一部下屋を形成して、建物ユニット４７の床構造材としての床根太４５ａと屋根ユニット４８の水平材である鼻隠し材６０が隣接して接合している。
そして、締結金具２０ｂが、図１０のＢ部に示す様に、３階床根太４５ａと、下屋を形成している屋根ユニット４８の構造材としての鼻隠し材６０との水平接合に用いられている。屋根ユニット４８は鼻隠し材６０、タルキ材６２、トラス材６１等で構成されている。
図１０のＢ部において、床根太４５ａと鼻隠し材６０とは水平な構造材として形成され、且つ同一軸芯に設けられている。その為屋根ユニットの水平方向の接合に隣接する建物ユニット４７の床根太４５ａを利用することができる。
【００２７】
図１２の様に、建物ユニット４７の床パネル１０ｄを構成している床構造材としての床根太４５ａと直交する床根太４５ｂの内側面に締結金具２０ｂが取り付けられている。
締結金具２０ｂは床根太４５ｂに固定されて、係止部２８は床根太４５ｂに接している。又、床根太４５ｂには締結ボルトを挿入可能に挿通孔５１ａが設けられている。隣接するトラス材６１にも同様に挿通孔５１ｂが設けられている。
一方、床根太４５ａと同一軸芯をなす鼻隠し材６０の内側面に締結金具２０ｂが取り付けられている。そして締結金具２０ｂの係止部２８の挿通孔２５ａは床根太４５ａの締結金具２０ｂの挿通孔２５ａと同一軸芯と成る様になされている。尚、床パネル１０ｄと屋根ユニットの位置はスペーサー４０で軸芯を調整している。
【００２８】
締結金具２０ｂは、図１１の様に、構造材に固定できる取付け片２７と締結ボルト２２を係止できる係止部２８からなっている。
建物ユニット４７の床パネルと屋根ユニットの接合構造において、締結金具２０ｂが、隣接するそれぞれの構造材に設けられた挿通孔５１ａ、５１ｂより締結ボルト２２を挿通して、締結ボルト２２の両端を係止部の挿入孔２５ａよりそれぞれ挿入係止して床構造材と隣接する屋根構造材を締結可能になされている。従って、建物の下屋部に取り付けられた建物ユニット４７と屋根ユニット４８の接合を更に強固な接合構造とする事が出来る。以上の実施例は、建物ユニットについて説明したが、パネルで構成される軸組み工法でも適用できるのは勿論である。
【００２９】
【発明の効果】
請求項１記載の本発明の建物ユニットの接合構造は、隣接する建物ユニット間の接合強度を向上させることができ、これによって３階を有するユニット建物においても、その接合強度の向上により、強固な建物を構築できる。
【００３０】
また、取付け片が座金付きボルトで締結されているので、締結金具の取付けが容易となる。従って、ユニット建物の接合構造として好適である。
【００３１】
請求項２記載の建物ユニットの接合方法において、締結ボルトを、あらかじめ一方の建物ユニットの床パネル締結孔から挿入して床パネル内に没入させておき、その後、建物ユニットを突き合わせて配置し、その後上記締結ボルトを引き出して他方の建物ユニットの床パネルにまで股がらせ、それぞれの床パネルに固着された締結金具に締結するので、床根太と床根太のピッチが締結ボルトの長さより小さい時でも床パネル同士の締結作業を容易に行うことが出来る。
【００３２】
また、締結金具があらかじめ工場にて、組み立てられているので、現場の組み立て手間が軽減され、施工コストを削減することができる。
【００３３】
請求項３記載の建物ユニットの接合構造において、直交する床構造材の床パネル内側面に取り付けられた板状片が略直角に交わってなる締結金具が、それぞれの板状片に挿通孔を備え、締結ボルトを挿通孔より挿通して、隣接する建物ユニットの床パネルのそれぞれの床構造材に取り付けられた締結金具と締結ボルトで締結されているので、締結ボルト同士が干渉することなく隣接する構造材同士を接合することができる。
【００３４】
請求項４記載の建物ユニットの接合構造において、構造材に固定できる取付け片と締結ボルト係止部からなる締結金具が、隣接するそれぞれの構造材に設けられた挿通孔より締結ボルトを挿通して、締結ボルトの両端を係止部の挿通孔よりそれぞれ挿入して床構造材と隣接する屋根構造材が締結されているので、床構造材と隣接する屋根構造材の締結において、構造強度を確保した接合構造とすることができる。
