Description

【０００１】
【発明の属する技術分野】
本発明はユニット建物を構成する建物ユニットの連結構造に関する。
【０００２】
【従来の技術】
従来、ユニット建物は、特公昭６２−６２２２４号公報に記載あるように、運搬可能な一定の大きさの箱形の、且つ、内部、外部の仕上げられた建物ユニットを、予め、工場で製造し、この建物ユニットの複数個を施工現場に運搬し、施工現場で組み立てて建物となすもので、現場施工期間が短く、且つ、寸法精度のよい標準化された建物となる特徴があるから広く採用されている。
【０００３】
このユニット建物を構成する建物ユニットの構造は種々あるが、上記公報に記載あるように、矩形状の四隅に立設した柱と、この柱の下端部を矩形状の辺に沿って連結した断面コ字形長尺体の床梁と、柱の上端部を矩形状の辺に沿って連結した断面コ字形長尺体の天井梁とからなる骨格を有する建物ユニットが多く使用されている。
そして、この建物ユニットを水平方向と垂直方向に据え付けた後に、相互に連結してユニット建物とするのである。
【０００４】
この下階の天井梁と上階の床梁とを連結する方法としては種々あるが、特公昭３−７０５５号公報に記載されて知られている方法が多く採用されている。
この公報に記載されている連結方法は、上階の断面コ字形の床梁の下側フランジと、下階の断面コ字形の天井梁の上側フランジに、それぞれ通孔を設け、この両方の通孔にボルトを通し、このボルトに螺入されたナットで巻き締めて、上階の床梁と下階の天井梁とを連結する。
この方法では、ボルトを通すために、予め設けられている上階の床梁の下側フランジの通孔と、下階の天井梁の上側フランジの通孔とを合わせる必要があるが、この両方の通孔の位置を合わせることが困難で作業し難い。
【０００５】
この連結方法を改良し、通孔を合わせる必要のない方法で、床梁の下側フランジと天井梁の上側フランジを連結する方法が実公平６−２２７２５号公報に記載されている。
この実公平６−２２７２５号公報に記載されている方法は連結金具を使用するものである。
【０００６】
即ち、連結金具は、略コ字形に折曲された本体とこの本体の両端を内側に折り返した押さえ片とからなる挟着部材と、この挟着部材のコ字形本体の両側のフランジに設けられている通孔に貫通させて締め付けるボルト・ナットの締付部材とからなるものであり、上階の床梁の下側フランジと下階の天井梁の上側フランジのコ字形の開口から中に挟着部材の押さえ片を入れ、本体のコ字形の両側のフランジに設けられている通孔にボルトを貫通させ、この先端からナットを螺入することによって、挟着部材の本体の両側のフランジをボルト・ナットからなる締付部材で締め付けて、この本体の先端に設けられている押さえ片で、上階の床梁の下側フランジと下階の天井梁の上側フランジとを押圧して連結するように使用するものである。
【０００７】
この方法では、床梁の下側フランジと天井梁の上側フランジとに通孔を設ける必要がなく、適宜場所を連結することができ極めて便利である。
一方、上記建物ユニットの断面コ字形長尺体の天井梁や床梁床は開口の先端部分が曲がり易く座屈し易い形状をしている。
従って、この断面コ字形長尺体の上側フランジと下側フランジを補強板で連結して補強することが望ましい。
【０００８】
【発明が解決しようとする課題】
しかし、断面コ字形長尺体の上側フランジと下側フランジとを補強板で連結して補強すると、断面コ字形の開口が塞がれる。従って、この断面コ字形の開口の中に手を入れて、特公昭５３−７０５５号公報に記載されている上階の床梁の下側フランジと下階の天井梁の上側フランジとをボルト・ナットで連結することができなくなるし、実公平６−２２７２５号公報に記載されている挟着部材の押さえ片を断面コ字形の開口の中に入れることができず、その結果、この連結金具で下階の天井梁の上側フランジと上階の床梁の下側フランジを連結することができなくなる。
【０００９】
又、断面コ字形の上階の床梁の下側フランジと下階の天井梁の上側フランジとを連結金具で連結した構造では、この連結金具の押さえ片が床梁の下側フランジや天井梁の上側フランジの表面を滑って、連結金具が床梁や天井梁から外れることがある。
そこで、本発明の目的は、断面コ字形長尺形の天井梁と床梁の下側フランジと上側フランジとを補強板で連結して補強していても、上階の床梁の下側フランジと下階の天井梁の上側フランジを連結金具で、押さえ片が滑らないように、強固に連結できる建物ユニットの連結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、断面コ字形長尺体の天井梁を備えた下階の建物ユニットの上に断面コ字形長尺体の床梁を備えた上階の建物ユニットが据え付けられたユニット建物の天井梁と床梁とを連結する建物ユニットの連結構造であって、前記天井梁と床梁には、それぞれ断面コ字形長尺体の上側フランジと下側フランジとを連結する補強板が取り付けられ、この補強板に開口が設けられ、この天井梁に取り付けられている補強板の開口と床梁に取り付けられている補強板の開口から中に一部が挿入された連結金具で天井梁の上側フランジと床梁の下側フランジが連結されているものである。
【００１１】
請求項１記載の発明における連結金具とは、床梁の下側フランジと天井梁の上側フランジとを連結する金具のことがあって、例えば、万力等でもよいが、請求２に記載されている連結金具が好ましい。
【００１２】
即ち、請求項２記載の発明は、請求項１記載の発明に係り、前記連結金具が梁挿入側の先端を内側に折り返した形状の押さえ片を有する２枚の板状体と、この２枚の板状体を接近する方向に前進させる締付機構とからなるものである。
【００１３】
この請求項２記載の発明における締付機構とは、２枚の板状体の先端の押さえ片を接近する方向に前進させるものであって、押さえ片を床梁に取り付けられた補強板の開口と、天井梁に取り付けられた補強板の開口から、床梁や天井梁の断面コ字形の中に挿入した後、この締付機構で押さえ片を接近する方向に前進させて、この間にある下階の天井梁の上側フランジと上階の床梁の下側フランジとを押圧して、床梁と天井梁とを連結するように使用するものである。
【００１４】
かかる締付機構としては種々ある。
例えば、実公平６−２２７２５号公報に記載されているように、通孔を有する２枚の板状体を略コ字形に連結するウェブと、ボルトと、ナットとからなり、この２枚の板状体の先端の押さえ片をそれぞれ床梁に取り付けられた補強板の開口と、天井梁に取り付けられた補強梁の開口から中に挿入し、両方の板状体に設けられている通孔にボルトを通し、このボルトにナットを螺入して、ウェブを中心にして２枚の板状体を回動させて、２枚の板状体の先端に設けられている押さえ片を接近する方向に前進させ、この押さえ片の間にある床梁の下側フランジと天井梁の上側フランジを押圧するようにした締付機構でもよい。
【００１５】
又、このウェブがバネ片であり、２枚の板状体の先端をジャッキ等で開らいて、両方の押さえ片をそれぞれ床梁に取り付けられている補強板の開口と天井梁に取り付けられている補強板の開口から中に挿入し、先端を開いている力を取り除くと、バネ片の弾性によりこの両方の押さえ片が接近する方向に前進して、この間にある床梁の下側フランジと天井梁の上側フランジを押圧するようにした締付機構でもよい。
【００１６】
又、２枚の通孔を有する板状体の押さえ片の反対側の縁部の先端を、押さえ片と同様に、内側に折り返した当接片と、ボルトと、このボルトに螺入するナットとからなり、この２枚の板状体の先端の押さえ片をそれぞれ床梁に取り付けられた補強板の開口と、天井梁に取り付けられた補強板の開口から中に挿入して、この２枚の板状体の押さえ片を天井梁の上側フランジと床梁の下側フランジを挟んで対峙させると同時に２枚の板状体の当接片を合わせた後、両方の板状体の通孔にボルトを通し、このボルトにナット螺入して両方の板状体の押さえ片と当接片とを接近する方向に更に前進させて、床梁の下側フランジと天井梁の上側フランジを押圧するようにした締付機構でもよい。
【００１７】
請求項３記載の発明は、請求項２記載の発明に係り、前記補助板の開口が補強板の上下の側縁を若干残した位置に設けられ、前記連結金具の押さえ片の折り返した部分の長さが挿入される天井梁又は床梁のウェブと補強板の残した縁部との間の距離に略等しいか若干短くなされているものである。
【００１８】
（作用）
請求項１記載の発明では、天井梁と床梁には、それぞれ断面コ字形長尺体の上側フランジと下側フランジとを連結する補強板が取り付けられているので、この天井梁と床梁は補強板で補強され、座屈しない。
しかも、この補強板に開口が設けられ、この天井梁に取り付けられている補強板の開口と床梁に取り付けられている補強板の開口から中に一部が挿入された連結金具で天井梁の上側フランジと床梁の下側フランジが連結されている。かかる構造にするには、下階の建物ユニットの天井梁の上側フランジと、上階の建物ユニットの床梁の下側フランジとを連結している補強板の開口から中に連結金具の一部を挿入し、挿入した先端を接近する方向に前進させて、天井梁の上側フランジと床梁の下側フランジを挟んで連結すればよい。
このように、請求項１記載の発明は、このように天井梁と床梁を簡単に、且つ、強固に連結できる構造をしている。
【００１９】
請求項２記載の発明では、連結金具が梁挿入側の先端を内側に折り返した形状の押さえ片を有する２枚の板状体と、この２枚の板状体を接近する方向に前進させる締付機構とからなる。かかる構造にするには、２枚の板状体の先端の押さえ片をそれぞれ床梁に取り付けられた補強板の開口と、天井梁に取り付けられた補強板の開口から中に挿入し、締付機構で、２枚の板状体を接近する方向に前進させて、下階の建物ユニットの天井梁の上側フランジと、上階の建物ユニットの床梁の下側フランジを押圧して強固に締結すればよい。
このように、請求項２記載の発明は、このように天井梁と床梁を簡単に、且つ、強固に連結できる構造をしている。
【００２０】
請求項３記載の発明では、開口が補強板の上下の縁部を若干残した位置に設けられている。かかる構造にするには、次に示すようにすればよい。
即ち、連結金具の押さえ片を開口から中に挿入し、締付機構で２枚の板状体を接近する方向に前進させると、この板状体の先端の押さえ片が天井梁又は床梁のウェブと補強板の残した縁部の間に入ってゆく。
このように押さえ片が入ってゆくと、この連結金具の押さえ片の折り返した部分の長さが挿入される天井梁又は床梁のウェブと補強板の残した縁部との間の距離に略等しいか若干短くなされているので、この天井梁又は床梁のウェブと補強板の残した縁部の間に入った板状体の押さえ片は、ウェブと残した縁部とに邪魔されて、前後に移動できない状態になる。
【００２１】
その後、締付機構で２枚の板状体を接近する方向に更に前進させると、上階の床梁の下側フランジと下階の天井梁の上側フランジとを押さえ片で押圧すると、連結金具が、天井梁又は床梁から外れない状態になって、下側フランジと上側フランジが強固に締結される。
このように、請求項３記載の発明は、このように天井梁と床梁を簡単に、且つ、強固に連結できるし、締付機構が外れない構造をしている。
【００２２】
【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５は本発明の一の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１階の建物ユニットを示す一部切欠斜視図、図３は図１のＡ部分の斜視図、図４は連結金具を示す斜視図、図５（イ）は１階の床梁（又は２階の天井梁）の主要部を示す斜視図、（ロ）は（イ）の正面図、（ハ）は（イ）の側面図である。
【００２３】
図１〜図５において、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９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９個の建物ユニット１がをえ付けて２階を形成し、この２階の建物ユニット１の上に屋根パネル３を取り付けたものである。
【００２４】
このユニット建物Ｕに使用される建物ユニット１は、図２に示すように、矩形の四隅に立設した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した４本の鋼製の断面コ字形長尺体の床梁１２と、この４本の柱１１の上端部を矩形の辺に沿って連結した４本の鋼製の断面コ字形長尺体の天井梁１３とからなる骨格を備えている。
【００２５】
そして、この建物ユニット１は、この骨格の相対する長辺の床梁１２、１２に複数本の鋼製の四角筒体の床小梁１５を略平行に差し渡して取り付け、この床小梁１５の上に複数本の木製の床根太１６を取り付け、この上にパーチクルボードの床材１４を取り付けて床を形成し、相対する長辺の天井梁１３、１３に複数本の木製の天井野縁１７を略平行に差し渡して取り付け、この天井野縁１７の下面に石膏ボードの天井材１８を取り付けて天井を形成したものである。
【００２６】
この床梁１２と天井梁１３には、開口４１を設けた補強板４が取り付けられている。
この補強板４の取付構造は、図５に示すように、断面コ字形の上側フランジ１２１（１３１）と下側フランジ１２２（１３２）に開口４１を設けた補強板４を差し渡し、上側フランジ１２１（１３１）と補強板４の一端を、又、下側フランジ１２２（１３２）と補強板４の他端を、それぞれ溶接して取り付けた構造をしている。
尚、外壁を設ける場所には、床梁１２と天井梁１３との間に間柱１９を取り付け、この間柱１９の屋外側と屋内側にそれぞれ外壁材と内壁材を取り付け、この外壁材と内壁材との間にガラスウールの断熱材を設けて壁を形成する。
【００２７】
５は連結金具であり、この連結金具５は、図４に示すように、２枚の板状体６と締結機構７とからなる。
板状体６には、梁挿入側の先端を折り返した押さえ片６１が設けられている。又、この板状体６には、通孔６２が設けられている。
【００２８】
締結機構７は、ウェブ７１と、ボルト７２と、ナット７３とからなる。
ウェブ７１は、上記２枚の板状体６の他端を連結する鋼板である。ボルト７２は板状体６の通孔６２に通すことができる径を有し、ナット７３はボルト７２に螺合するものである。
そして、図３に示すように、２枚の板状体６の押さえ片６１を１階の天井梁１３に取り付けられている補強板４の開口４１と床梁１２に取り付けられている補強梁４の開口４１から中に挿入し、２枚の板状体６の通孔６２にボルト７２を貫通させ、このボルト７２にナット７３を螺入して巻き締めると、板状体６がウェブ７１を中心にして回動して、２枚の板状体６の先端に設けられている押さえ片６１が接近する方向に前進して、この押さえ片６１の間にある２階の床梁１２の下側フランジ１２２と１階の天井梁１３の上側フランジ１３１とを押圧して連結できるようになっている。
屋根パネル３は従来の屋根パネルとほぼ同じであるので説明を省略する。
【００２９】
次に、このユニット建物Ｕの施工方法および作用について説明する。
工場で、建物ユニット１、屋根パネル３等を製造する。
この際、床梁１２には、床梁１２の断面コ字形の上側フランジ１２１と下側フランジ１２２に開口４１を設けた補強板４を差し渡して取り付けておくし、又、天井梁１３には、天井梁１３の断面コ字形の上側フランジ１３１と下側フランジ１３２に開口４１を設けた補強板４を差し渡して取り付けておく。
このように、天井梁１３と床梁１２に補強板４を取り付けておくと、この天井梁１３と床梁１２が補強板４で補強され、座屈しないようになる。
【００３０】
このようにして製造した建物ユニット１、屋根パネル３を施工現場に運搬する。
施工現場では、予め設けられている基礎９の上に、９個の建物ユニット１を据え付け、この建物ユニット１の隣接する天井梁１３同士や隣接する床梁１２同士を連結して１階を形成し、この１階の建物ユニット１の上に９個の建物ユニット１を据え付け、この建物ユニット１の隣接する天井梁１３同士や床梁１２同士を連結したり、１階の建物ユニット１の天井梁１３と２階の建物ユニット１の床梁１２とを連結して２階を形成し、この２階の建物ユニット１の上に屋根パネル３を取り付けたり、種々な仕上げを行うと、ユニット建物Ｕが完成する。
【００３１】
この際の１階の建物ユニット１の天井梁１３と２階の建物ユニット１の床梁１２を連結する連結方法について、詳細に説明する。
１階の建物ユニット１の４本の柱１１の上に２階の建物ユニット１の４本の柱が載るようにして、１階の建物ユニット１の上に２階の建物ユニット１を据え付ける。
【００３２】
すると、図５に示すように、１階の建物ユニット１の天井梁１３の上に、２階の建物ユニット１の床梁１２が相対するようになる。
次に、１階の建物ユニット１の天井梁１３に取り付けられている補強板４の開口４１と、２階の建物ユニット１の床梁１２に取り付けられている補強板４の開口４１に、連結金具５の押さえ片６１を先頭にして板状体６の一部を中に挿入し、２枚の板状体６の通孔６２にボルト７２を貫通させ、このボルト７２にナット７３を螺入して巻き締める。
【００３３】
すると、２枚の板状体６の先端に設けられている押さえ片６１が接近する方向に前進して、この押さえ片６１の間にある２階の建物ユニット１の床梁１２の下側フランジ１２２と１階の建物ユニット１の天井梁１３の上側フランジ１３１が押圧されて強固に連結される。
尚、この２階の建物ユニット１の床梁１２の下側フランジ１２２と１階の建物ユニット１の天井梁１３の上側フランジ１３１との間に隙間があってボルト７２・ナット７３で巻き締め難いようであれば、この間にスペーサーを挟むとよい。
【００３４】
このように、天井梁１３や床梁１２に補強板４を設けて補強していても、連結金具５で天井梁１３の上側フランジ１３１と床梁１２の下側フランジ１２２とを簡単に、且つ、強固に連結できるので、極めて便利である。
【００３５】
（実施例２）
図６は本発明の他の実施例を示すもので、床梁（天井梁）に補強板を取り付けた状態を示す斜視図である。
【００３６】
この図６に示す実施例２を、図１〜図５に示す実施例１と比較すると、補強板４ａが上側フランジ４２ａと下側フランジ４３ａとウェブ４４ａとからなることが異なる。
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。
【００３７】
このように、上側フランジ４２ａと下側フランジ４３ａとが設けられていると、補強板４ａの強度がフランジの殆どない実施例１の補強板より大きい。
しかも、この上側フランジ４２ａと下側フランジ４３ａが長い程、機械的強度が大きくなる。従って、この上側フランジ４２ａと下側フランジ４３ａの長さを調節することにより、場所によって異なる天井梁１３ａと床梁１２ａを、その場所に最適な機械的強度にすることができ、極めて便利である。
その他の施工方法および作用は実施例１と略同じであるので、説明を省略する。
【００３８】
（実施例３）
図７は本発明の別の実施例を示すもので、床梁（天井梁）に補強板を取り付けた状態を示す断面図である。
【００３９】
この図７に示す実施例３を、図１〜図５に示す実施例１と比較すると、補強板４ｂに開口４１ｂが、補強板４ｂの下側の縁部４５ｂと上側の縁部４６ａを若干残した位置に設けられていること、連結金具５ｂの下側の押さえ片６１ｂの折り返した部分の長さが、挿入される天井梁１３ｂのウェブ１３３ｂと、補強板４ｂの下側の縁部４５ｂとの間の距離にほぼ等しくなっているし、上側の押さえ片６１ｂの折り返した部分の長さが、挿入される床梁１３ｂのウェブ１３３ｂと、補強板４ｂの上側の縁部４６ｂとの間の距離にほぼ等しくなっていることが異なる。
【００４０】
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。
このように、補強板４ｂの開口４１ｂが、補強板４ｂの下側の縁部４５ｂと上側の縁部４６ｂを若干残した位置に設けられていると、連結金具５ｂの押さえ片６１ｂを補強板４ｂの開口４１ｂから中に挿入した後に、締付機構７ｂで２枚の板状体６ｂを接近する方向に前進させたときに、上側の押さえ片６１ｂが床梁１２ｂのウェブ１２３ｂと補強板４ｂの間に、又、下側の押さえ片６１ｂが天井梁１３ｂのウェブ１３３ｂと補強板４ｂの間にそれぞれ入ってゆく。
【００４１】
このように押さえ片６１ｂが入ってゆくと、連結金具５ｂの押さえ片６１ｂの下側の折り返した部分の長さが挿入される天井梁１３ｂのウェブ１３３ｂと補強板４ｂの補強板４ｂの残した下側の縁部４５ｂの間の距離に略等しいし、連結金具５ｂの押さえ片６１ｂの上側の折り返した部分の長さが挿入される床梁１２ｂのウェブ１２３ｂと補強板４ｂの残した上側の縁部４６ｂの間の距離に略等しいので、連結金具５ｂの下側の押さえ片６１ｂの折り返した部分は、この天井梁１３ｂのウエブ１３３ｂと補強板４ｂの下側の残された縁部４５ｂに挟まれて前後に移動できない状態になるし、連結金具５ｂの上側の押さえ片６１ｂの折り返した部分は、この床梁１２ｂのウエブ１２３ｂと補強板４ｂの残した上側の縁部４５ｂに挟まれて前後に移動できない状態になる。
【００４２】
その後、締付機構７ｂで２枚の板状体６ｂを接近する方向に更に前進させると、連結金具５ｂの押さえ片６１ｂが天井梁１３ｂの上側フランジ１３１ｂや床梁１２ｂの下側フランジ１２２ｂから外れない状態になって、天井梁１３ｂと床梁１２ｂを連結金具５ｂで簡単に、且つ、強固に締結することができる。
その他の施工方法および作用は実施例１とほぼ同じであるので、説明を省略する。
【００４３】
（実施例４）
図８は本発明の更に別の実施例を示すもので、床梁と天井梁を連結金具で連結した状態を示す断面図である。
【００４４】
この図８に示す実施例４を、図１〜図５に示す実施例１と比較すると、連結金具５ｃの構造が異なる。
即ち、実施例４に示す連結金具５ｃは、２枚の板状体６ｃと締結機構７ｃとからなることは略同じであるが、この締結機構７ｃが、２枚の板状体６ｃを略コ字形に連結したウェブ７１ｃだけであり、ボルトやナットがないこと、ウェブ７１ｃがバネ片であることが異なる。
その他の構造は略同じであるので、説明を省略する。
【００４５】
この連結金具５ｃで床梁１２ｃと天井梁１３ｃとを連結する連結方法は、この連結金具５ｃのウェブ７１ｃの間にジャッキを挿入して、このジャッキで、２枚の板状体６ｃの先端を開らいて、板状体６ｃの先端に設けられている両方の押さえ片６１ｃをそれぞれ床梁１２ｃに取り付けられている補強板４ｃの開口４１ｃと天井梁１３ｃに取り付けられている補強板４ｃの開口４１ｃから中に挿入した後、先端を開いているジャッキを取り除くと、ウェブ７１ｃであるバネ片の弾性によりこの両方の押さえ片６１ｃが元の形状に戻ろうとして、接近する方向に前進して、この間にある床梁１２ｃの下側フランジ１２２ｃと天井梁１３ｃの上側フランジ１３１ｃを押圧し、その結果、床梁１２ｃと天井梁１３ｃとが簡単に、且つ、強固に連結される。
その他の施工方法および作用は実施例１とほぼ同じであるので、説明を省略する。
【００４６】
（実施例５）
図９及び図１０は本発明の更に別の実施例を示すもので、図９（イ）は連結金具を分解して示す斜視図、（ロ）は（イ）の連結金具を組み立てた正面図、図１０は床梁と天井梁を連結金具で連結した状態を示す一部切欠斜視図である。
【００４７】
この図９及び図１０に示す実施例５を図１〜図５に示す実施例１と比較すると、連結金具５ｄの構造が異なる。
即ち、連結金具５ｄは、通孔６２ｄを有する２枚の板状体６ｄと締結機構７ｄとからなることは略同じであるが、締結機構７ｃが、２枚の通孔を有する板状体６ｃの押さえ片７１ｃの反対側縁部の先端を、押さえ片６１ｃと同様に、内側に折り返した当接片７９ｄと、ボルト７２ｄと、このボルト７２ｄに螺入するナット７３ｄとからなり、ウェブがないことが異なる。
その他の構造は実施例１と略同じであるので説明を省略する。
【００４８】
この連結金具５ｄで床梁１２ｄと天井梁１３ｄとを連結する連結方法は、この２枚の板状体６ｄの先端の押さえ片６１ｄをそれぞれ床梁１２ｄに取り付けられた補強板４ｄの開口４１ｄと、天井梁１３ｄに取り付けられた補強板４ｄの開口４１ｄから中に挿入して、この２枚の板状体６ｄの押さえ片６１ｄを天井梁１３ｄの上側フランジ１３１ｄと床梁１２ｄの下側フランジ１２２ｄを挟んで対峙させると同時に２枚の板状体６ｄの反対側縁部の当接片７９ｄを合わせる。
【００４９】
その後、２枚の板状体６ｄの通孔６２ｄにボルト７２ｄを通し、このボルト７２ｄにナット７３ｄ螺入して２枚の板状体６ｄの押さえ片６１ｄと当接片７９ｄとを接近する方向に前進させる。
すると、この押さえ片６１ｄが床梁１２ｄの下側フランジ１２２ｄと天井梁１３ｄの上側フランジ１３１ｄを押圧して、床梁１２ｄと天井梁１３ｄとを簡単に、且つ、強固に連結することができる。
その他の施工方法および作用は実施例１とほぼ同じであるので、説明を省略する。
【００５０】
【発明の効果】
請求項１記載の発明は、天井梁と床梁には、それぞれ断面コ字形長尺体の上側フランジと下側フランジとを連結する補強板が取り付けられ、この補強板に開口が設けられ、この天井梁に取り付けられている補強板の開口と床梁に取り付けられている補強板の開口から中に一部が挿入された連結金具で天井梁の上側フランジと床梁の下側フランジが連結されているから、この天井梁と床梁は補強板で補強され、座屈しないし、下階の建物ユニットの天井梁の上側フランジと、上階の建物ユニットの床梁の下側フランジとを連結金具で簡単に、且つ、強固に取り付けることができる構造をしている。
【００５１】

BACKGROUND OF THE INVENTION
The present invention relates to a connecting structure of building units constituting a unit building.
[0002]
[Prior art]
Conventionally, as described in Japanese Examined Patent Publication No. 62-62224, a unit building is manufactured in advance in a factory in a box-shaped, interior and exterior finished building having a certain size that can be transported. The building unit is transported to the construction site and assembled at the construction site to form a building. The site construction period is short, and it is widely adopted because it has the characteristics of a standardized building with good dimensional accuracy. ing.
[0003]
There are various structures of building units that make up this unit building, but as described in the above publication, a cross-section in which rectangular columns are erected at the four corners and the lower ends of the columns are connected along the rectangular sides. A building unit having a skeleton composed of a U-shaped long floor beam and a ceiling beam having a U-shaped long cross section in which upper ends of columns are connected along a rectangular side is often used.
Then, after the building units are installed in the horizontal direction and the vertical direction, they are connected to each other to form a unit building.
[0004]
There are various methods for connecting the lower floor ceiling beam and the upper floor beam, and many methods known in Japanese Patent Publication No. 3-7055 are employed.
In the connection method described in this publication, through holes are respectively provided in the lower flange of the upper floor U-shaped floor beam and the upper flange of the lower floor U-shaped ceiling beam. Bolts are passed through the holes and wound with nuts screwed into the bolts to connect the upper floor beams to the lower floor beams.
In this method, in order to pass bolts, it is necessary to match the holes of the lower flange of the upper floor beam provided in advance with the holes of the upper flange of the lower floor beam. It is difficult to align the position of the through-holes and it is difficult to work.
[0005]
Japanese Utility Model Publication No. 6-22725 discloses a method of improving the connection method and connecting the lower flange of the floor beam and the upper flange of the ceiling beam in a method that does not require matching of the through holes.
The method described in this Japanese Utility Model Publication No. 6-22725 uses a connecting bracket.
[0006]
That is, the connecting bracket is provided on a sandwiching member composed of a main body bent into a substantially U-shape and holding pieces that are folded back at both ends of the main body, and flanges on both sides of the U-shaped main body of the sandwiching member. The bolts and nuts are tightened through the through-holes. The lower flange of the upper floor beam and the upper flange of the upper floor beam are sandwiched between the U-shaped openings. Insert the holding piece of the attachment member, pass the bolt through the holes on the flanges on both sides of the U-shape of the main body, and screw in the nut from this tip, the flange on both sides of the main body of the sandwiching member Tighten with bolts and nuts, and press and connect the lower flange of the upper floor beam to the upper flange of the lower floor ceiling beam with the holding piece provided at the tip of this body. It is intended to be used.
[0007]
