Description

【０００１】
【発明の属する技術分野】
本発明は、住宅などにおいて上階床部下面に取り付けられるナット付き水平支持材を備えた建物の上部躯体の支持構造に関する。
【０００２】
【背景の技術】
住宅の構築においては、その工業化が進み、例えば、壁や床、屋根といった構成要素を予め工場にてパネル化しておき、施工現場でこれらのパネルを組み立てることにより、住宅を構築するといったパネル工法が一部に採用されている。
このパネル工法で使用される壁パネルは、框材を矩形枠状に組み立てるとともにこの矩形枠の内部に補強用桟材を縦横に組み付けてなる枠体の表裏両面に合板等からなる面材を取り付けたものであり、中空部を備えている。また、床パネルは框材を矩形状に組み立てるとともにこの矩形枠の内部に補強用桟材を縦横に組み付けてなる枠体の一方の表面に合板等からなる面材を取り付けたものである。
【０００３】
このパネル工法では、例えば特開平１０−０５４４１３号公報に示すように、上階の壁パネルが組み付けられている。
まず、下階の壁パネルの上階に床部（床パネル等で構成される）を介して上階の壁パネルを立設する一方で、胴差ボルトをその下端部が下階の壁パネルの中空部内に配置され、かつその上端部が上階の壁パネルの中空部内に配置されるようにして、下階の壁パネルと上階の壁パネルとに亙って設ける。ここで、下階の壁パネルの上端部、上階の壁パネルの下端部及び床部には、胴差ボルトが通される貫通孔が予め形成されており、胴差ボルトはこれらの貫通孔を通って下階の壁パネルと上階の壁パネルとに亙って設けられる。ついで、胴差ボルトの下端部に座金を外挿した後にナットを螺合させる一方で、胴差ボルトの上端部に座金を外挿した後にナットを螺合させることで、下階の壁パネルと上階の壁パネルとを連結する。
【０００４】
ところで、上述したパネル工法においては、上階の壁パネルを上階の床パネルを介して下階の壁パネルに連結し、該下階の壁パネルに支持させているが、上階の壁パネルを上階の床パネルを挟んで中空部を備えていないまぐさに連結し、これら壁パネル及び床パネルを支持させる場合は、例えば図８及び図９に示すような構造が採用されている。
【０００５】
すなわち、床パネル１３１上に壁パネル１３２を建て起こす前に、床パネル１３１に形成されたボルト挿通孔１３３に胴差ボルト１３４を挿通するとともに、床パネル１３１の枠材１３１ａに形成された切欠部１３５を介して、胴差ボルト１３４の下端にナット１３６を螺合させる。この状態で、床パネル１３１上に壁パネル１３２を建て起こした後、胴差ボルト１３４の上端を壁パネル１３２のボルト挿通孔１３７に挿通するとともに、その胴差ボルト１３４の上端にナット１３８を螺合させて、壁パネル１３２を床パネル１３１に締め付け固定する。
【０００６】
続いて、床パネル１３１の切欠部１３５の両側開口面にパッキン材１３９を接着剤により接着して、床パネル１３１の枠材１３１ａと床パネル１３１を支持するマグサ１４０との間の表面段差を補修する。この状態で、各パッキン材１３９及びマグサ１４０の表面にガセット合板１４１を接着剤により接着するとともに、各ガセット合板１４１上から床パネル１３１の枠材１３１ａ及びマグサ１４０に複数の釘１４２を打ち込む。これにより、床パネル１３１とマグサ１４０との間を接合固定するとともに、床パネル１３１の切欠部１３５の両側開口面を閉塞している。
【０００７】
【発明が解決しようとする課題】
しかし、上述したように上階の壁パネルを上階の床パネルを挟んでまぐさと連結することで前記上階の壁パネル及び上階の床パネル等の上部躯体をまぐさに支持させる構造においては、前述のように、床パネル１３１と壁パネル１３２との締め付け固定、及び床パネル１３１とマグサ１４０との間の固定を別々に行っているため、現場施工が面倒で手間がかかる。
【０００８】
本発明の課題は、上部に設けられる床パネルなどの上部躯体を容易に固定して支持することができる上部躯体の支持構造を提供することである。
【０００９】
【課題を解決するための手段】
以上の課題を解決するため、請求項１記載の発明は、例えば、図５に示すように、
ナット付き水平支持材１上に、下面７１にナット３が挿入される切欠部７７と切欠部７７に連通する床側連通孔７４とが形成された上階床部７が、前記切欠部７７内にナット３を収容し且つ該ナット３と床側連通孔７４とが連通した状態で載置され、
支持材本体（例えばまぐさ本体２）と、前記上部躯体に設けられるボルト（例えば胴差ボルト７３）と螺合するナット３と、ナット３の下部に設けられた雄ネジ部４０とを備え、前記ナット３は、前記雄ネジ部４０を支持材本体２の上面２１に設けられた下穴２２に接着剤５を充填してねじ込むことで前記支持材本体２に固定され、前記ナット３は前記支持材本体２の上面２１に取り付けられており、
前記上階床部７上に、前記上階床部７とともに建物の上部躯体を構成するとともに、前記床側連通孔７４に連通する壁側連通孔７５が形成された上階壁部７６が立設され、
前記壁側連通孔７５及び床側連通孔７４に、上端が前記上階壁部７６内で係止されるボルト７３が挿通されて、このボルト７３の下端部を前記ナット付き水平支持材のナット３に螺合することで上階床部７及び上階壁部７６がナット付き水平支持材１に連結されており、
前記上階床部７は、端面どうしを合わせた複数の床パネル７ａ，７ｂにより構成され、これら床パネル７ａ，７ｂの端面にはそれぞれ上下方向に延在する溝が形成され、床パネル７ａ，７ｂ端面どうしを合わせることで、床側連通孔７４及び切欠部７７が形成されており、前記ナット３は、このナット３に床パネル７ａの切欠部７７となる溝を合わせることによって前記切欠部内に収容されていることを特徴とする。
【００１０】
請求項１記載の発明によれば、支持材本体２に、上部躯体に設けられるボルト７３と螺合するナット３が雄ネジ部４０及び接着剤５を介して固定されているので、上部躯体の下部に取り付ける際に、前記上部躯体のボルト７３に前記ナット３を螺合するだけで、前記上部躯体は支持材本体２に連結固定される。これにより、上部躯体をナット付き水平支持材に取り付けて支持させる作業を容易に行うことができ、現場施工での簡略化は勿論のこと施工期間の短縮化を図ることができる。すなわち、水平支持材２上に上部躯体をとりつける際に、従来と異なり、水平支持材と上部躯体、つまり上階床部の下部とを接続するための金具、例えば、ガセット合板等を必要とせずに容易に固定支持させることができる。
【００１１】
ここで、前記水平支持材は、建物躯体の一部、特に建物躯体の下部躯体を構成し、水平に設置され、その上部に設けられる上部躯体、例えば、上面に載置される上階床部を支持するものであればどのようなものでもよく、例えば、下階部分分に離間配置された壁間の開口部の上側に配置される部材、特に梁やまぐさ等でもよい。
また、前記ナット３と雄ネジ部４０とは一体のものとして構成されていてもよいし、また、雄ネジ部４０を支持材本体２に固着した後、前記雄ネジ部４０にナット３の下端部３２を螺合してなるものとしてもよい。その際、ナット３における雄ネジ部４０が螺合した下端部より上方の部分では、上階床部７に設けられるボルト７３を確実に螺合できるように構成されている。つまり、ボルト７３が確実に螺合できる分のネジ深さを有するものとする。
【００１９】
また、支持材本体２の上面２１からナット３が突出した状態となり、上部躯体を上部に設けて連結させる際に、ナット３の位置を容易に視認でき、前記上階床部７に設けられるボルト７３に簡単に螺合することができる。
【００２１】
また、ナット付き水平支持材上に設けられる上部躯体が、上部躯体に設けられたボルトをナット付き水平支持材のナットに螺合されることで前記ナット付き水平支持材に支持されているので、ナット付き水平支持材１０に上部躯体７，７６を取り付ける際に、前記ボルトをナット付き水平支持材１０のナット３に螺合させるだけで、前記上部躯体７６，７をナット付き水平支持材１０に容易に連結して支持させることができる。これにより、上部躯体と水平支持部材とを連結して、前記上部躯体を支持させる作業を現場施工での簡略化は勿論のこと施工期間の短縮化を図ることができる。
【００２６】
また、ナット３が支持材本体２の上面２１に取り付けられているナット付き水平支持材１上に、前記ナット３が挿入される切欠部７７と、切欠部７７に連通する床側連通孔７４とが形成された上階床部７が、前記切欠部７７にナット３を収容した状態で載置され、この上階床部７上に、前記床側連通孔７４に連通する壁側連通孔７５が形成された上階壁部７６が立設され、上端が前記上階壁部内で係止されるとともに前記壁側連通孔７５及び床側連通孔７４に挿通されたボルト７３が前記ナット３に螺合されることでナット付き水平支持材１が上階床部７及び上階壁部７６に連結されているので、ナット付き水平支持材１上に上部躯体を構成する上階壁部及び上階床部７を設けて支持させる際に、上階床部を前記水平支持材１上に載置し、この上階床部上に上階壁部７６を立設し、前記上階壁部７６の壁側連通孔７５及び上階床部７の床側連通孔７４にボルト７３を挿通してナット付き水平支持材のナット３に螺合させるだけで、前記上階壁部７６及び上階床部７をナット付き水平支持材１に連結させることができる。
【００２７】
したがって、ナット付き水平支持材１上に載置された上階床部７上で該上階床部７及び上階壁部７６のナット付き水平支持材１への取付作業を容易に行うことができる。すなわち、従来と異なり、水平支持材であるまぐさに上階床部７を取り付ける際に、水平支持材と上階床部とを接続するための金具、例えば、ガセット合板等を必要とせず、さらに、上階床部７とこの上階床部７上に立設された上階壁部７６とをボルト７３で連結するためのボルト７３とナット３の締結作業を上階床部７の下方で行う必要がなく、上階床部７上にて水平支持材に上階床部７及び上階壁部７６を容易に連結することで、前記上階床部７を上階壁部とともに前記水平支持材１に容易に支持させることができる。
さらに、ナット付き水平支持材上に前記上階床部７を載置する際に、上階床部７を水平支持材上面から突出するナット３に、下面７１の切欠部７７を合わせて設置することができ、上階床部７の設置位置の位置決めを容易に行うことができる。
【００３０】
【発明の実施の形態】
以下、図を参照して本発明の実施の形態を詳細に説明する。
まず、構成を説明する。
図１に示すナット付きまぐさ（水平支持材）１は、上部に設けられる上階床部７を支持する（図５参照）ものであり、まぐさ本体２と、まぐさ本体２の上面２１に取り付けられ、且つ上階床部７に設けられるボルト７３と螺合するナット３と、ナット３の下部に設けられるとともにナット３を前記まぐさ本体２に固定する雄ネジ部４０とを備え、ナット３は、雄ネジ部４０をまぐさ本体２の上面２１に設けられた下穴２２に、接着剤５を充填してねじ込むことでまぐさ本体２に固定されている。
【００３１】
まぐさ本体２は、直方体の角材であり、建物内において下部躯体の上部分、ここでは、下階に離間して配置された壁の上端部間に、前記壁間に亘って架設され、下方に開口部を形成するものである。なお、本実施の形態では、上階床部７を構成する床パネル７ａ，７ｂの下面７１に、上面２１を当接させた状態で取り付けるられるものとしている。
【００３２】
雄ネジ部４０は、この実施の形態ではコーチボルトの軸部により構成され、その上部にナット３の下端部が螺合されたナット用雄ネジ部４１が設けられている。また、このナット用雄ネジ部４１の上部には、雄ネジ部４０をまぐさ本体２にねじ込むためのねじ込み部４２が設けられており、これら雄ネジ部４０、ナット用雄ネジ部４１及びねじ込み部４２は全て同一軸心を有する軸部材４として一体に成形されたものである。さらに雄ネジ部４０の外周には、基端から先端まで軸方向に沿う溝部４４が形成されている。この溝部４４は、雄ネジ部４０を接着剤５が充填された下穴２２にねじ込む際に、下穴２２内における余剰の接着剤５を上方に案内するためのものである。
【００３３】
ねじ込み部４２は、その外径がナット用雄ネジ部４１の外径が小さく前記ナット３内に収納されている。また、ねじ込み部４２は、本実施の形態では六角柱状の部材からなり、めがねレンチなどの工具の連結部に内嵌されるようになっている。また、ねじ込み部４２は、六角柱状としたがこれに限らず、角形の穴を有する筒状部材から構成し、この角形の穴にレンチ、ドライバー、スパナなどの工具を嵌めて、工具を介して雄ネジ部４０をねじ込むようにしてもよい。
このように構成された雄ネジ部４０は、接着剤５を充填させた下穴２２ねじ込まれている。また、本実施の形態では雄ネジ部４０の外径と下穴２２の内径は略同一としている。
【００３４】
ナット３は、その下端部で雄ネジ部４０に設けられたナット用雄ネジ部４１に螺合されることで、上方でボルト７３を螺合可能な状態、つまり、ボルト７３が確実に螺合できるネジ孔深さを有し、雄ネジ部４０に固着されたものとなっている。そして、雄ネジ部４０を介してまぐさ本体２の上面２１に取り付けられた状態となっている。ここで、ナット３と軸部材４とは、ナット３の下部に雄ネジ部４０が設けられるような一体のものとして構成されていてもよい。ナット３と軸部材とが一体のものであれば、まぐさ本体２への取付作業が容易に行える。
【００３５】
図３及び図４にナット付きまぐさ１の製作方法を示す。
図３（ａ）で示すように、まず、まぐさ本体２の上面２１に穿孔機８１で所定の内径を有する下穴２２を穿孔する。このときの内径は、後でねじ込まれる雄ネジ部４０の外径に対応させた長さとし、本実施の形態では、雄ネジ部４０の外径及び全長と略同じ長さの内径及び全長を有する下穴２２を形成する。
このように雄ネジ部４０の外径と下穴２２の内径が略同一であることにより、雄ネジ部４０は、接着剤５が充填された下穴２２に容易にねじ込むことができるとともに、充填された接着剤５を介して強固にまぐさ本体２に止着され、ナット３をまぐさ本体２に強固に固定できるようになっている。
【００３６】
そして、図３（ｂ）に示すように、まぐさ本体２に形成された下穴２２内に接着剤容器８２により接着剤５を注入して充填する。
次いで、この接着剤５が充填された下穴２２に、ねじ込み部４２とねじ込み工具、例えば、レンチ、スパナ、ドライバー等の工具を連結させて雄ネジ部４０を、その軸を中心に回転させることでねじ込み、まぐさ本体２の上面２１からナット用雄ネジ部４１が突出した状態にさせる。
そして、雄ネジ部４０を所定の深さまでねじ込んだ後、工具をねじ込み部４２から外し、図４に示すように、まぐさ本体２に止着された雄ネジ部４０の上部のナット用雄ネジ部４１に、ナット３の下端部を螺合させることで、ナット付きまぐさ１を作成する。
【００３７】
次に、ナット付きまぐさ１上に建物の上部躯体である上階床部及び上階床部上に立設される上階壁部を取り付けて支持させた構造を説明する。なお、ナット付きまぐさ１は、どのように構築された住宅に用いられても良いが、この実施の形態では、パネル工法により構築される住宅に適用されるものとし、上階床部、上階壁部はそれぞれ床パネル７ａ，７ｂ及び壁パネルにより構成されるものとして説明する。
【００３８】
図５に示すナット付きまぐさ１の取り付け構造では、ナット付きまぐさ１上に、下面７１にナット３が挿入される切欠部７７と、切欠部７７に連通する床側連通孔７４が形成された上階床部７が前記切欠部７７内にナット３が収容され且つ該ナット３と床側連通孔７４とが連通した状態で載置されている。
上階床部７は、床パネル７ａ，７ｂを並べることで構成されており、床側連通孔７４は胴差しボルト７３が挿通する内径を有し、切欠部７７はナット３が内部で収容される内径を有している。ここでは、切欠部７７と、上階床部７の上下に貫通する床側連通孔７４とは同一の内径となっており、同一の穴を穿孔することで形成されている。さらに、上階床部７上には、床側連通孔７４に連通する壁側連通孔７５が形成された上階壁部７６が立設されている。
【００３９】
上階壁部７６は、壁パネルにより構成され内部に中空部を有するととともに、壁パネルの本体となる矩形枠を構成する下框材に上下に連通する壁側連通孔７５が形成されている。この壁側連通孔７５は、床側連通孔７４の内径と略同一の内径を有するものであり、胴差ボルト７３の軸部が挿通されている。
そして、壁側連通孔７５及び床側連通孔７４に、胴差ボルト７３が挿通されてナット付きまぐさ１のナット３に螺合することでナット付きまぐさは上階床部７及び上階壁部７６に連結されている。つまり、胴差ボルト７３の上端部は、上階壁部７６内部で座金８６を介してナット８７により止着され、上階壁部７６を構成する壁パネルの下側横框材７６１上面に係止された状態となっている。
この胴差ボルト７３、上階床部７を介してナット付きまぐさ１は上階床部７に取り付けられた状態となっている。
【００４０】
次に、ナット付きまぐさ１上に上部躯体を構成する上階床部７及び上階壁部７６を設けて支持させる方法を説明する。
まず、例えば工場等にて、ナット付きまぐさ１を作成し、建築現場に搬入した後、図６（ａ）に示すように、所定の箇所に設置する。図６（ａ）では、壁パネル９１を接合してなる下階壁部９の上端部に平板状の補強材９２を介してまぐさ受け金具９３が取り付けられ、このまぐさ受け金具９３にナット付きまぐさ１の一端部を嵌め込み、まぐさ本体２が下階壁部９に対して直交し、且つ上面２１が下階壁部９の上面９４と略面一となるように配置されている。
このように下階壁部９のまぐさ受け金具９３に嵌め込まれたナット付きまぐさ１の下部には開口部９５が形成された状態となる。
【００４１】
なお、図示しないが、ナット付きまぐさ１の他端部は、建物の下部躯体を構成する下階の内壁を構成する壁パネルの側端面の上部に接合される等して固定され、これらまぐさ受け金具９３等を介して下階壁部９や下階の内壁により支持された状態となっている。
このように所定の箇所に設置されたナット付きまぐさ１では、まぐさ本体２の上面２１からナット３が上方に突出した状態となっており、このナット付きまぐさ１の上部に、吊り治具８５を介して吊り上げられた上階床部７を構成する床パネル７ａを設置する（図６（ｂ）参照）。なお、吊り治具８５はクレーン等のワイヤーの先端に取り付けられて、吊り上げ自在となっている。また、ナット付きまぐさ１上に載置される上階床部７は、端面どうしを合わせた複数の床パネル７ａ，７ｂにより構成され、これら床パネル７ａ，７ｂの端面にはそれぞれ上下方向に延在する溝が形成され、床パネル７ａ，７ｂ端面どうしを合わせることで、床側連通孔７４及び切欠部７７が形成されるものとなっている。
【００４２】
ナット付きまぐさ１の上に上階床部７を構成する床パネル７ａを設置する際には、まぐさ本体２の上面２１にナット３が突出した状態で取り付けられているので、このナット３に床パネル７ａの切欠部７７となる溝を合わせるようにして載置できる。つまり、上階床部７の下面７１に取り付けられる際に、ナット３の位置を容易に視認して、上階床部７に設けられるボルト７３に螺合することができ、ナット３を床パネル７ａの位置決めに用いて正確な設置箇所に床パネル７ａを載置することができる。
そして、図７に示すように、上方から胴差ボルト７３の軸部をナット３に螺合させることで、胴差ボルト７３の上端部を床パネル７ａの上面から上方に突出させるとともに、既に載置された床パネル７ａに並べるように、床パネル７ｂを載置する。
【００４３】
このとき載置される床パネル７ｂは、胴差ボルト７３の先端部に端面の溝部を合わせて載置させることができ、その載置作業が容易なものとなっている。
このようにナット付きまぐさ１上に床パネル７ａ，７ｂを並べて載置した後、床パネル７ａ，７ｂどうしの接合部分に上階壁部７６となる壁パネルを、壁側連通孔に胴差ボルト７３の先端部を挿入させて立設するとともに、壁パネルの中空部内で座金８６を介してナット８７を螺合することでナット付きまぐさ１、上階床部７及び上階壁部７６を連結することで、上階壁部７６とナット付きまぐさ１をと締結させ、上階壁部７６及び上階床部７等からなる建物の上部躯体をナット付きまぐさ１に取り付け、支持させた状態にする。
【００４４】
また、雄ネジ部４０の上部に、ナット３の下端部３２が螺合されたナット用雄ネジ部４１が設けられていることにより、ナット３と雄ネジ部４０とは分割可能であるとともに、雄ネジ部４０のナット用雄ネジ部４１の上部には、ナット用雄ネジ部４１より外径が小さくナット３内に収納され、雄ネジ部４０を下穴２２にねじ込むためのねじ込み部４２が設けられているので、まぐさ本体２にねじ込み部を介して雄ネジ部４０をねじ込んだ後で、ねじ込まれた雄ネジ部４０の上部のナット用雄ネジ部４１にナット３の下端部３２を螺合することで、ナット３をまぐさ本体２に固定することができる。
つまり、ナット３及び雄ネジ部４０を一体に形成する必要がなく、その成形にかかるコストを削減することができる。
【００４５】
また、上階床部７及び上階壁部７６等から構成される上部躯体をナット付きまぐさ１に取り付ける作業の際に、ナット３がまぐさ本体２の上面２１に取り付けられているナット付きまぐさ１上に、ナット３が挿入される切欠部７７と、切欠部７７に連通する床側連通孔７４とが形成された上階床部７が、切欠部７７にナット３を収容した状態で載置され、この上階床部７上に、床側連通孔７４に連通する壁側連通孔７５が形成された上階壁部７６が立設され、壁側連通孔７５及び床側連通孔７４に挿通され、且つ上端が上階壁部７６内で螺合されたナット８７により壁パネルの横框材７６１に係止されるボルト７３がナット３に螺合されることでナット付きまぐさ１が上階床部７及び上階壁部７６に連結されているので、ナット付きまぐさ１を上階床部７に取り付ける際に、上階壁部７６の壁側連通孔７５及び上階床部７の床側連通孔７４にボルト７３を挿通してナット付きまぐさのナット３に螺合させるだけで、上階壁部７６及び上階床部７をナット付きまぐさ１に連結できる。
【００４６】
したがって、ナット付きまぐさ１上に載置された上階床部７上で上部壁部７６及び上部床部７等からなる上部躯体とナット付きまぐさとの連結作業を容易に行うことができ、従来と異なり、上階床部７をまぐさに取り付ける際に、まぐさと上階床部７とを接続するための金具、例えば、ガセット合板等を必要とせず、さらに、上階床部７とこの上階床部７上に立設された上階壁部７６とをボルト７３で連結するためのボルト７３とナット３の締結作業を上階床部７の下方で行う必要がなく、上階床部７上にて上階床部７及び上階壁部７６をまぐさ１に容易に連結することで容易に取り付けまぐさ１に支持させることができる。
【００４７】
詳細には、床パネルと壁パネルとの締め付け固定、及び床パネルとマグサとの接合を同時に行うことができ、現場施工を簡略化、施工期間の短縮化を図ることができるとともに、組付け強度を向上させることができる。さらに、まぐさに外装材が取り付けられる場合でもまぐさと床パネルとの接合にガセット合板を用いることがないので、ガセット合板が邪魔になることなく容易に外装材の取付作業を行うことができる。
【００６０】
上記実施の形態では、まぐさを水平支持材として説明したが、建物躯体の一部、特に建物躯体の下部躯体を構成し、水平に設置され、その上部に設けられる上部躯体、例えば、上面に載置される上階床部を支持するものであればどのようなものでもよく、例えば、梁としてもよい。
なお、上記実施の形態及び変形例では、ナット３と雄ネジ部４０とは別体のものとして説明したが、ナット３と雄ネジ部４０とを一体のものとして構成されていてもよい。
また、上階床部及び上階壁部等の構成も任意であり、例えば、上階壁部を壁パネルとしたが、これに限らず、角材を用いてもよい。その他、具体的な構成要素等についても適宜に変更可能であることは勿論である。
【００６１】
【発明の効果】
請求項１記載の発明によれば、支持材本体に、上階床部に設けられるボルトと螺合するナットが雄ネジ部及び接着剤を介して固定されているので、上階床部の下部に取り付ける際に、前記上部躯体のボルトに前記ナットを螺合するだけで、前記上部躯体は支持材本体に固定される。これにより、上部躯体をナット付き水平支持材に取り付けて支持させる作業を容易に行うことができ、現場施工での簡略化は勿論のこと施工期間の短縮化を図ることができる。
すなわち、水平支持材を上部躯体の下部にとりつける際に、従来と異なり、水平支持材と上部躯体、つまり上階床部の下部とを接続するための金具、例えば、ガセット合板等を必要とせずに容易に固定支持させることができる。
【００６５】
また、支持材本体の上面からナットが突出した状態となり、上階床部の下面に取り付けられる際に、ナットの位置を容易に視認することができ、前記上階床部に設けられるボルトに簡単に螺合することができる。
【００６６】
また、ナット付き水平支持材に上部躯体を取り付ける際に、前記ボルトをナット付き水平支持材のナットに螺合させるだけで、前記上部躯体をナット付き水平支持材に容易に支持させることができ、上部躯体と水平支持部材とを連結して、前記上部躯体を支持させる作業を現場施工での簡略化は勿論のこと施工期間の短縮化を図ることができる。
【００６８】
また、ナット付き水平支持材に上部躯体を構成する上階壁部及び上階床部を支持させる際に、上階床部を前記水平支持材上に載置し、この上階床部上に上階壁部を立設し、前記上階壁部の壁側連通孔及び上階床部の床側連通孔にボルトを挿通してナット付き水平支持材のナットに螺合させるだけで、前記上階壁部及び上階床部をナット付き水平支持材に連結させることができるので、ナット付き水平支持材上に載置された上階床部上でその作業を容易に行うことができ、前記上階床部７及び上階壁部を前記水平支持材に容易に支持させることができる。
さらに、ナット付き水平支持材上に前記上階床部７を載置する際に、上階床部を水平支持材上面から突出するナットに、下面の切欠部を合わせて設置することができ、上階床部の設置位置の位置決めを容易に行うことができる。
