【発明の属する技術分野】
本発明は、建物の据付構造、建物ユニット及びユニット建物並びに床金物に関する。
【０００２】

従来、床パネルの上部に壁パネルを立設してなる建物ユニットが用いられている。この建物ユニットを基礎の上に据付けるに際しては、特公平５−３８１０２号公報に記載の如く、基礎に植設してあるアンカーボルトを床パネルの土台（下枠）に貫通し、該土台に緊結することとしている。
【０００３】
【発明が解決しようする課題】
しかしながら、従来技術では、建物ユニットと基礎との接合構造が、基礎側のアンカーボルトを床パネルの土台に緊結することのみにより構成されているから、接合強度の向上に限界がある。
【０００４】
本発明の課題は、建物ユニット等の建物と基礎との接合強度を向上することにある。
【０００５】
【課題を解決するための手段】
請求項１に記載の本発明は、床構造体の上部に壁パネル又は柱を立設してなる建物の据付構造において、床構造体の下部に第一の床金物が格納され、床構造体の構造材の上面にボルト付き座金の座金部を添設し、該座金部から下方に延在されたボルト部を前記第一の床金物に緊結し、床構造体の下部に第二の床金物が格納され、壁パネル又は柱の垂直面に引き寄せ金物が取り付けられ、該引き寄せ金物を前記第二の床金物にボルトにより緊結して床構造体の上部にパネル又は柱が立設され、基礎に植設してあるアンカーボルトを、前記第一の床金物と第二の床金物のうち少なくとも第一の床金物に緊結してなるようにしたものである。
【０００６】
請求項２に記載の本発明は、床構造体の上部に壁パネル又は柱を立設してなる建物ユニットにおいて、床構造体の下部に、第一の床金物が格納され、床構造体の構造材の上面にボルト付き座金の座金部を添設し、該座金部から下方に延在されたボルト部を前記第一の床金物に緊結してなり、床構造体の下部に第二の床金物が格納され、壁パネル又は柱の垂直面に引き寄せ金物が取り付けられ、該引き寄せ金物をボルトにより前記第二の床金物に緊結して床構造体の上部に壁パネル又は柱を立設してなり、前記第一の床金物と第二の床金物とを、基礎に植設してあるアンカーボルトを緊結可能に形成したものである。

請求項１に記載の本発明によれば下記（１）の作用がある。
（１）建物を基礎に据付けるに際し、基礎側のアンカーボルトが床構造体に格納してある第一の床金物に緊結される。そして、第一の床金物は、床構造体の構造材の上面に添設されたボルト付き座金のボルト部に緊結され、床構造体の全体と強固に一体化されている。従って、アンカーボルトは、単に床構造体に接合されるものでなく、ボルト付き座金と緊結されて床構造体の全体と強固に一体化されている第一の床金物と緊結されるものであり、建物と基礎との接合強度を向上できる。また壁パネル及び柱を床構造体の上部に立設するに際し、壁パネル及び柱に取り付けられた引き寄せ金物が床構造体に格納してある第二の床金物に緊結される。そして、第二の床金物は、床構造体の構造材を挿通するボルトによって床構造体を抱きかかえる如く引き寄せ金物に緊結され、床構造体の全体と強固に一体化されている。従って、壁パネル及び柱は、単に床構造体に接合されるものでなく、第二の床金物と緊結されて床構造体の全体と強固に緊結されるものであり、床構造体と壁パネル及び柱との接合強度を向上できる。さらに第二の床金物は、第一の床金物と同様に基礎側のアンカーボルト部に緊結することができる。従って、壁パネル及び柱を立設する直下においてもアンカーボルトにより基礎と床構造体を緊結することができ、アンカーボルトの位置を壁パネル及び柱の位置とは無関係に設定することができる。
【００１０】
請求項２、３に記載の本発明によれば下記（２）の作用がある。

【００１１】
請求項４に記載の本発明によれば下記（３）の作用がある。
（３）第一の床金物に、建物ユニットの床構造体の構造材の上面に添設されたボルト付き座金のボルト部のための上支持部と、基礎に植設してあるアンカーボルトのための下支持部とを併せ備えるようにした。従って、床構造体に格納されている第一の床金物を用いることにより、建物ユニットと基礎との接合強度を向上できる。また第二の床金物に、該建物ユニットの床構造体の上部に立設される壁パネル又は柱を固定するボルトのための上支持部と、基礎に植設してあるアンカーボルトのための下支持部とを併せ備えるようにした。従って、床構造体に格納されている第二の床金物を用いることにより、建物ユニットと基礎との接合強度及び床構造体と壁パネル及び柱との接合強度を向上できるとともに、アンカーボルトの位置を任意に設定することができる。

【００１８】
引き寄せ金物４１は、図５に示す如く、壁パネル２１の縦枠２３の側面に添設される平板４２と、平板４２に溶接される支持板４３と、支持板４３を補強する補強板４４とを有する。平板４２にはボルト孔４２Ａが、支持板４３にはボルト孔４３Ａが設けられる。

尚、ユニット建物１０において、引き寄せ金物４１は壁内、即ち壁パネル２１の壁面材２５、２６に挟まれる縦枠２３の側面に固定されるようになっている。そして、ユニット建物１０にあっては、工場生産段階で、上記（イ）〜（ハ）により床パネル１１と壁パネル２１とを接合した後、内壁面材２６を取着完了することとしている。
【００２３】
従って、建物ユニット１０によれば、以下の作用がある。建物ユニット１０において、床パネル１１の上部に壁パネル２１を立設するに際し、床パネル１１に格納した第二の床金物３１に固定したボルト３８と、壁パネル２１の縦枠２３の側面に固定した引き寄せ金物４１とを緊結することとした。従って、第二の床金物３１は、床パネル１１を抱きかかえる如くにして壁パネル２１の縦枠２３に固定した引き寄せ金物４１に緊結され、床パネル１１と壁パネル２１との接合強度を向上できる。
【００２４】

【００２８】
（建物ユニットと基礎との接合構造）（図１〜図３、図８）
図１〜図３のユニット建物１００は、上述の建物ユニット１０を基礎１の上に据付けて構築される。このとき、基礎１は建物ユニット１０の壁パネル２１における縦枠２３の位置と無関係な位置を、アンカーボルト２の標準位置として定めたものであり、本実施形態では、縦枠２３に固定した引き寄せ金物４１とボルト３８で緊結された第二の床金物３１がアンカーボルト２の位置から外れたものとなっている。このため、本実施形態の建物ユニット１０では、床パネル１１におけるアンカーボルト２に対応する位置に上述の第一の床金物３１Ａ、ボルト付き座金５１を設け、この第一の床金物３１Ａの下支持部３４にアンカーボルト２を緊結したものである。アンカーボルト２は、第一の床金物３１Ａの下支持部３４のボルト孔３４Ａを通って座金３、ナット４にて締結される。
【００２９】
尚、建物ユニット１０における壁パネル２１の縦枠２３に固定した引き寄せ金物４１とボルト３８で緊結された第二の床金物３１が、基礎１におけるアンカーボルト２の標準位置に対応するものであれば、この第二の床金物３１の下支持部３４にアンカーボルト２を緊結できる（図８）。

（Ｂ）壁パネル２１を床パネル１１の上部に立設するに際し、壁パネル２１に取り付けられた引き寄せ金物４１が床パネル１１に格納してある第二の床金物３１に緊結される。そして、第二の床金物３１は、床パネル１１の根太１２を挿通するボルト３８によって床パネル１１を抱きかかえる如く引き寄せ金物４１に緊結され、床パネル１１の全体と強固に一体化されている。従って、壁パネル２１は、単に床パネル１１に接合されるものでなく、第二の床金物３１と緊結されて床パネル１１の全体と強固に緊結されるものであり、床パネル１１と壁パネル２１との接合強度を向上できる。
【００３１】
（Ｃ）第一の床金物３１Ａは、建物ユニット１０の床パネル１１の根太１２の上面に添設されたボルト付き座金５１のボルト部５３のための上支持部３３と、基礎１に植設してあるアンカーボルト２のための下支持部３４とを併せ備えるようにした。従って、床パネル１１に格納されている第一の床金物３１Ａを用いることにより、建物ユニット１０と基礎１との接合強度を向上できる。
（Ｄ）第二の床金物３１は、建物ユニット１０の床パネル１１の上部に立設される壁パネル２１を固定するボルト３８のための上支持部３３と、基礎１に植設してあるアンカーボルト２のための下支持部３４とを併せ備えるようにした。従って、床パネル１１に格納されている第二の床金物３１を用いることにより、建物ユニット１０と基礎１との接合強度及び床パネル１１と壁パネル２１との接合強度を向上できるとともに、アンカーボルト２の位置を任意に設定することができる。
【００３２】
