【０００１】
【発明の属する技術分野】
本発明は、例えば床スラブを構成するデッキプレートとこの床スラブの階下に設けられる間仕切壁の接合構造に関する。
【０００２】
【従来の技術】
図１３は、デッキプレートと間仕切壁の接合構造の従来例を示す断面図であり、デッキプレートのリブ部と間仕切壁が平行をなす場合について示す。
デッキプレート１００の板部１１０の上面１１１にコンクリート１０２を打設して床スラブ２００が構成されている。
デッキプレート１００は、板部１１０の下面１１２に互いに間隔をおいて互いに平行に延在する複数のリブ部１２０を備えている。リブ部１２０は、板部１１０の下面１１２から立設される壁部１２１によって構成されている。
そして、この床スラブ２００の階下に間仕切壁３００が設けられている。
間仕切壁３００とデッキプレート１００の接合は次のような手順で行われる。
【０００３】
図１４に示されているように、隣接する２つのリブ部１２０の下部の間にわたって延在するフラットバー３０１を複数個リブ部１２０の延在方向に沿って間隔をおいてリブ部１２０に取着する。
フラットバー３０１に軽鉄製のランナー３０２を打ち付けて取着する。ランナー３０２はデッキプレート１００の下方にある図略の床スラブにも打ち付けて取着される。
そして、上下のランナー３０２に上下方向に延在する柱材であるスタットを支持材として建て込み、このスタットの両面または片面に石膏ボード、珪酸カルシウム板などの板材３０３を釘、ステップル（タッカー）などにより貼り付けて間仕切壁３００を構成する。
間仕切壁３００を構成する板材３０３の間には耐火性を有するロックウールまたは多孔質吸音材３０４が充填される。
間仕切壁３００の上部をデッキプレート１００に固定するランナー３０２はリブ部１２０の下部に固定されることが多いため、デッキプレート１００の板部１１０の下面１１２と間仕切壁３００の上部との間に隙間があき、遮音性に欠ける。
【０００４】
したがって、遮音性能を確保するためには、デッキプレート１００の板部１１０の下面１１２と間仕切壁３００の上部との間に形成される隙間を防ぐために次のような対策が必要である。
第１に、床スラブ２００の形成後にデッキプレート１００のリブ部１２０を切断などにより除去する。
第２に、間仕切壁３００の上方におけるリブ部１２０で囲まれる空間に多孔質吸音材３０５を充填する。
第３に、デッキプレート１００の板部１１０の下面１１２と間仕切壁３００の上部との間に形成される隙間に耐火モルタルなどを塗り付けまたは吹き付けことにより隙間を充填する。
【０００５】
また、間仕切壁３００の上方におけるリブ部１２０と板部１００の下面１０２とフラットバー３０１の上面とで囲まれる空間を多孔質吸音材３０５などで埋める場合には、次に示すような問題がある。
すなわち、リブ部１２０の高さは６０ｍｍから１００ｍｍ程度、隣接するリブ部１２０の間隔は２００ｍｍ程度であり、一方、間仕切壁３００の厚さは１００ｍｍ〜１５０ｍｍ程度である。したがって、間仕切壁３００をリブ部１２０の間に構築しようとすると、間仕切壁３００の上部とデッキプレート１００の板部１１０との間に手が入らないために間仕切壁３００の上部の工事が困難となってしまう。
また、間仕切壁３００の位置がリブ部１２０の位置と合致している場合には、リブ部１２０の下場で間仕切壁３００を構築し、間仕切壁３００の上部とリブ部１２０の下部との間の空間を埋めるようにすることが多い。また、この場合には、遮音性能を確保するため、間仕切壁３００の上部のリブ部１２０の部分に対しても対策を行う必要がある。
【０００６】
また、図１５デッキプレートと間仕切壁の接合構造の従来例を示す断面図であり、図１６は、図１５を矢印Ａ方向から見た状態を示す立面図であり、デッキプレートのリブ部と間仕切壁が直交する場合について示す。
この場合も図１３、図１４と同様の手順で間仕切壁３００を構築する。
この際、同様にデッキプレート１００の板部１１０の下面１１２と間仕切壁３００の上部との間に隙間があき、遮音性に欠けるため、上述したのと同様の対策が必要となる。
また、前述したようにリブ部１２０の高さは６０ｍｍ〜１００ｍｍ程度、リブ部１２０の間隔は２００ｍｍ程度、リブ部１２０の下端部のリブ部の延在方向と直交する方向の厚みは６０ｍｍ程度が普通である。このため、実質的なリブ部１２０の間隔は１５０ｍｍ程度となり、リブ部１２０の下部で間仕切壁３００を構築する場合、リブ部１２０と間仕切壁３００の上部の間で細かい作業を行うことは難しい。
また、デッキプレート１００の板部１１０の下面１１２と間仕切壁３００の上部との間に隙間を埋める方法としては、リブ部１２０の下端位置まで間仕切壁３００を構築し、間仕切壁３００の上部とデッキプレート１００の板部１１０の下面１１２の隙間を埋めるか、図１６に示されているように、板材３０３の上部をリブ部１２０の間隔に合わせた凸状に切断加工し隙間を埋めて詰め物をする方法もある。
【０００７】
【発明が解決しようとする課題】
しかしながら、上述した各方法は手間が掛かるだけでなく、十分な遮音性能を期待できない、また、遮音性能にばらつきが生じ易く均一になり難いという問題がある。
本発明は、上記のような事情のもとになされたもので、その目的は、手間が掛からず、均一で優れた遮音性能を確保できるデッキプレートと間仕切壁の接合構造を提供することにある。
【０００８】
【課題を解決するための手段】
本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、前記複数のリブ部の下方に前記リブ部の延在方向に沿って間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記デッキプレートを該デッキプレートの隣り合う２つのリブ部の間隔よりも大きい幅で切断してなる連結部材を設け、前記連結部材は前記リブ部を上方に向けてその板部の下面が間仕切壁の上端に取着されると共に、前記連結部材のリブ部が前記デッキプレートのリブ部の間に位置し、さらに、前記デッキプレートのリブ部の下面に連結部材の板部の上面が取着されることで配設されることを特徴とする。
【０００９】
そのため、連結部材とデッキプレートの間、連結部材と間仕切壁の上端の間を隙間なく接続することができるため、均一で優れた遮音性能を実現することができる。
また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
吸音材、遮音材、耐火材の少なくとも１つを間仕切壁の上方でデッキプレートのリブ部と連結部材のリブ部との間に間仕切壁の厚さ方向にわたって延在するように充填することが可能となる。
【００１０】
また、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、前記複数のリブ部の下方に前記リブ部の延在方向に沿って間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記デッキプレートの隣り合う２つのリブ部の間隔よりも大きい幅を有し、かつ、前記リブ部の延在方向に延在する底壁と、前記底壁の幅方向の両側部から起立される２つの側壁とを有する連結部材を設け、前記連結部材は前記２つの側壁を上方に向けてその底壁の下面が間仕切壁の上端に取着されると共に、前記２つの側壁が前記複数のリブ部のうち幅方向の外側に位置する２つのリブ部の外側に位置した状態で前記２つの側壁が前記板部の下面に取着されることで配設されることを特徴とする。
【００１１】
そのため、連結部材とデッキプレートの間、連結部材と間仕切壁の上端の間を隙間なく接続することができるため、均一で優れた遮音性能を実現することができる。
また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
吸音材、遮音材、耐火材の少なくとも１つを間仕切壁の上方で間仕切壁の厚さ方向にわたって延在するように、複数のリブ部の間に充填することが可能となる。
【００１２】
また、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、複数個の前記デッキプレートが前記リブ部の延在方向と直交する方向に所定の間隔をおいて建て込まれ、前記隣り合う２つのデッキプレートの間の下方に前記リブ部の延在方向に沿って間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記隣り合う２つデッキプレートの間で前記板部よりも下方の位置で前記リブ部の延在方向に延在する底壁と、前記底壁の幅方向の両側部から起立される２つの側壁とを有する連結部材を設け、前記連結部材は前記２つの側壁を上方に向けてその底壁の下面が間仕切壁の上端に取着されると共に、前記２つの側壁の上端部が前記隣り合う２つのデッキプレートの板部の側縁部に当接されて配設され、前記デッキプレートの板部の上面に打設されたコンクリートが、前記間仕切壁の上方で間仕切壁の厚さ方向にわたって延在するように、前記連結部材の底壁の上面と前記２つの側壁に囲まれた部分に充填されていることを特徴とする。
【００１３】
そのため、連結部材とデッキプレートの間、連結部材と間仕切壁の上端の間を隙間なく接続することができるため、均一で優れた遮音性能を実現することができる。
また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
また、連結部材の底壁の上面と２つの側壁に囲まれた部分に充填されたコンクリートによって優れた遮音性能を実現することができる。
【００１４】
また、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、前記複数のリブ部の下方に前記複数のリブ部の延在方向と交叉する方向に延在して間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記間仕切壁の延在方向に延在する底壁と、前記底壁の幅方向の両側部から前記底壁の長手方向に沿って起立された両側の側壁と、前記各側壁の長手方向に間隔をおいて設けられた上方に開放状の複数の切り欠きとを有する連結部材を設け、前記連結部材は前記複数の側壁を上方に向けてその底壁の下面が間仕切壁の上端に取着されると共に、前記複数の側壁が前記デッキプレートの隣り合う２つのリブ部の間をそれぞれ閉塞するように各リブ部が前記切り欠き内に収容され、かつ、前記複数の側壁の上端部が前記デッキプレートの板部の下面に取着されることで配設されることを特徴とする。
【００１５】
そのため、連結部材とデッキプレートの間、連結部材と間仕切壁の上端の間を隙間なく接続することができるため、均一で優れた遮音性能を実現することができる。
また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
また、吸音材、遮音材、耐火材の少なくとも１つを、間仕切壁の上方で間仕切壁の厚さ方向にわたって延在するように、両側の側壁と複数のリブ部の間に充填することが可能となる。
【００１６】
【発明の実施の形態】
次に、図面を参照して本発明のデッキプレートと間仕切壁の接合構造について説明する。
図１は本発明のデッキプレートと間仕切壁の接合構造の第１の実施の形態の構成を示す断面図、図２は第１の実施の形態における連結部材の斜視図である。
なお、以下に説明する第１乃至第４の実施の形態に対応する図１乃至図１２において、従来の接合構造と同一のまたは対応する部分には図１３乃至図１６と同一の符号を付してその説明を省略する。
【００１７】
まず、図１、図２を参照して第１の実施の形態の接合構造について説明する。
デッキプレートと間仕切壁の接合構造１０００は、デッキプレート１００と、間仕切壁３００と、連結部材４００とを備えて構成されている。また、間仕切壁３００はリブ部１２０の延在方向に沿って配設される。
【００１８】
デッキプレート１００は、コンクリート１０２が打設される上面１１１を有する板部１１０と、板部１１０の下面１１２に互いに間隔をおき互いに平行に延在する複数のリブ部１２０とを備えている。
リブ部１２０は、板部１１０の下面１１２から立設される壁部１２１と、壁部１２１の板部１１０と反対側に設けられ、壁部１２１の厚さ方向の寸法よりも大きな幅方向（リブ部１２０の延在方向と直交する方向）の寸法を有する端部１２２とを有している。端部１２２には上記下面１１２と平行をなし、リブ部１２０の延在方向に長手方向を有する帯状の平面部１２３が形成されている。
【００１９】
連結部材４００は、上記デッキプレート１００を、隣り合う２つのリブ部１２０の間隔よりも大きい幅で切断して構成されている。
図２に示されているように、連結部材４００は、デッキプレート１００と同様に、板部４１０と、板部４１０の上面４１１から立設される壁部４２１と、壁部４２１の板部４１０と反対側に設けられ、壁部４２１の厚さ方向の寸法よりも大きな幅方向（リブ部１２０の延在方向と直交する方向）の寸法を有する端部４２２とを有している。端部４２２には上記上面４１１と平行をなし、リブ部４２０の延在方向に長手方向を有する帯状の平面部４２３が形成されている。
また、板部４１０の上面４１１と下面４１２は、平坦な面として構成されている。
また、連結部材４００の長さは、デッキプレート１００のリブ部１２０の延在方向の長さと同程度とする。
【００２０】
連結部材４００は、リブ部４２０を上方に向けてその板部４１０の下面４１２が間仕切壁３００の上端３１０に取着されると共に、リブ部４２０がデッキプレート１００の隣り合う２つのリブ部１２０の間に位置し、さらに、デッキプレート１００の隣り合う２つのリブ部１２０の下面である平面部１２３に連結部材４００の板部４１０の上面４１１が取着されることで配設されている。
【００２１】
連結部材４００の板部４１０の下面４１２の間仕切壁３００の上端３１０への取着および連結部材４００の板部４１０の上面４１１のデッキプレート１００の隣り合う２つのリブ部１２０の平面部１２３への取着は、溶接などによって隙間なく行なわれる。
【００２２】
さらに、吸音材４３０が前記デッキプレート１００の隣り合う２つのリブ部１２０のうちの一方のリブ部１２０と連結部材４００のリブ部４２０との間に、間仕切壁３００の上方で間仕切壁３００の厚さ方向の全長にわたって、かつ、間仕切壁３００の延在方向にわたって延在するように充填されている。
【００２３】
次に上述したように構成された接合構造１０００の作用効果について説明する。
連結部材４００の板部４１０の上面４１１は、デッキプレート１００の隣り合う２つのリブ部１２０の平面部１２３へ隙間なく接続される。
また、連結部材４００の板部４１０の下面４１２は平坦な面として構成されているため、連結部材４００の板部４１０の下面４１２を間仕切壁３００の上端３１０およびランナー３０２との間に隙間なく接続することができる。
したがって、均一で優れた遮音性能を実現することができる。
また、デッキプレート１００に接続された連結部材４００に間仕切壁３００を接続する作業は、連結部材４００の下面４１２と間仕切壁３００の上端３１０を接続するのみでよいため、従来に比較して作業が容易である。
【００２４】
また、上記した連結部材４００のデッキプレート１００に対する溶接は、全周溶接でもよいし、スポット溶接でもよい。本出願人の実験によればスポット溶接で十分な遮音性能を確保できることが確認された。
また、連結部材４００のデッキプレート１００に対する取着は溶接に限定されるものではなく、例えば、エアーを用いた打ち付け、金物などによる打ち付けなどを用いることができる。
また、第１の実施の形態では、連結部材４００のデッキプレート１００への取着を床スラブ２００の施工後に行なうことができるため、間仕切壁３００を任意の位置に設けることができる利点がある。
【００２５】
また、この第１の実施の形態の接合構造１０００では、デッキプレート１００に対して間仕切壁３００を設ける位置が制約されることが無い。また、上階の床スラブ２００が構築された後で間仕切壁３００を設ける位置を任意に変更できる。
また、複数のデッキプレート１００がリブ部１２０の延在方向に並べて配設されたときに、隣り合うデッキプレート１００のリブ部１２０の延在方向と直交する方向の位置ずれがあっても、すなわち隣り合うデッキプレート１００のリブ部１２０が直線状に延在しなくても連結部材４００のリブ部４２０の間に上記リブ部１２０が位置すれば連結部材４００のデッキプレート１００への取着が可能となる利点もある。
【００２６】
また、上記接合構造１０００によれば、確保すべき遮音性能を、連結部材４００のリブ部４２０とデッキプレート１００のリブ部１２０の間に充填する吸音材の有無や、吸音材の量を調整することで容易に変更できる。吸音材としては、ロックウール、グラスウールなどの多孔質吸音材を使用できる。また、吸音材の代わりに遮音材、防火材を用いても良い。また、これらの吸音材、遮音材、防火剤は乾式、湿式のいずれであってもよい。
また、本例では、連結部材４００のリブ部４２０の数を２つとしたが、この数は２以上であってもよく、連結部材４００のリブ部４２０の数を増減することで上記接合構造１０００の遮音性能の程度を容易に変更調整することができる。すなわち、連結部材４００のリブ部４２０の数を増やせば遮音性能が向上され、減らせば遮音性能が減少される。
【００２７】
また、連結部材４００のリブ部４２０の数を増加させて板部４１０の幅方向の寸法を確保することにより、板部４１０の下面４１２の幅方向の寸法の範囲内で間仕切壁３００の延在方向を任意に設定することができる。
例えば、間仕切壁３００の延在方向がリブ部４２０の延在方向に対して交叉するような角度を有していてもかまわない。また、間仕切壁３００が直線状に延在しておらず、屈曲したり湾曲していてもかわない。
さらに、床スラブ２００を構成するデッキプレート１００の下部の全域を覆おうように連結部材４００を配設すれば、間仕切壁３００の延在方向の制約が無くなり、間仕切壁３００の施工方向が自由に選択することができる。
【００２８】
また、第１の実施の形態によれば、連結部材４００として床スラブ２００を構成するデッキプレート１００と同一のものを切断して使用する。したがって、建築材料の種類の増加がないため、部材の一括購入によるコストを削減でき、部材揚重計画の変更が不要となり、ストックヤード（部材置き場）の別途確保も不要となる。また、デッキプレート１００と間仕切壁３００とを接続するための部材が別に用意される場合と違って、部材の種類が少なくて済むので部材を誤認するといったミスも発生しない。
【００２９】
次に、テーパー状の形状を呈するデッキプレートを用いた場合について説明する。
図３は、リブ部がその延在方向の両端部でテーパ状に形成されている形態のデッキプレートの側面図である。デッキプレート１００Ａは、リブ部１２０の端部１２２が延在方向の両端部に向かうにつれて板部１１０の下面１１２に接近し、ついには下面１１２と一致するようなテーパ状を呈するように構成されている。
これは、デッキプレートのリブ部１２０の延在方向の両端部１２４を建物の梁Ｈの上面に載置するためである。
【００３０】
このような形態のデッキプレート１００Ａでは、以下のようにして連結部材を構成することができる。
第１に、第１の実施の形態の場合と同様に、デッキプレート１００Ａを切断して連結部材として使用する。この場合には、床スラブを構成するデッキプレート１００Ａと、連結部材としてのデッキプレート１００Ａとの双方の両端部１２４の部分に隙間が形成されるため、遮音性能が多少低下する。
第２に、連結部材としてのデッキプレート１００Ａを、リブ部１２０の延在方向の中間位置（すなわちテーパ状でない部分）で切断する。切断した部分を両端とし、テーパ状の部分の端部同士を接続することで連結部材とする。この場合には、床スラブを構成するデッキプレート１００Ａと、連結部材としてのデッキプレート１００Ａとの双方の両端部１２４による隙間がそれぞれ互いのリブ部１２０によって閉塞されるので第１の場合よりも遮音性能の低下が少なくて済む。
第３に、デッキプレート１００Ａのうち、テーパ状の部分を切り落とし、非テーパ状部分のみで連結部材を構成する。この場合には、床スラブを構成するデッキプレート１００Ａの両端部１２４による隙間が連結部材のリブ部１２０によって閉塞されるので第２の場合よりもさらに遮音性能の低下が少なくて済む。
【００３１】
図４は、第１の実施の形態で示した接合構造の遮音性能に関する評価結果を示す特性図である。
図４において、横軸は１／３オクターブ中心周波数、縦軸は音響透過損失をそれぞれ示している。すなわち、間仕切壁３００の一方の側で発生した音が間仕切壁３００の他方に伝わる度合いを計測して遮音性能を評価している。
実験条件は以下に示す５種類の条件である。
（条件１）間仕切壁単体
（条件２）従来の接合構造（デッキプレートのリブ部とランナーとの間にロックウールを充填した）
（条件３）第１の実施の形態の構成に加えて連結部材４００とデッキプレート１００のリブ部１２０の外側に面した箇所にモルタルなどを全面的に塗り付けた構成（図３では（本発明▲１▼[塗付全面]）と記載）
（条件４）第１の実施の形態の構成に加えて連結部材４００とデッキプレート１００のリブ部１２０の外側に面した箇所にモルタルなどを軽微に塗り付けた構成（図３では（本発明▲１▼[軽微な塗付]）と記載）
（条件５）第１の実施の形態の構成のままであって連結部材４００とデッキプレート１００のリブ部１２０の外側に面した箇所にモルタルなどを塗り付けていない構成（図３では（本発明▲１▼[基本]）と記載）
【００３２】
図４の実験結果から明らかなように、従来構造に比較して第１の実施の形態の接合構造で遮音性能が向上していることが明らかに示されている。また、（条件３）が最も優れた遮音性能を実現しており、以下、（条件４）、（条件５）の順番で遮音性能が低下していることがわかる。
また、これらの結果から、連結部材４００とデッキプレート１００のリブ部１２０の外側に面した箇所にモルタルなどの部材を塗り付けることで遮音性能を向上することができることがわかる。
【００３３】
図５は本発明のデッキプレートと間仕切壁の接合構造の第２の実施の形態の構成を示す断面図、図６は第２の実施の形態における連結部材の斜視図である。
まず、図５、図６を参照して第２の実施の形態の接合構造について説明する。
第２の実施の形態のデッキプレートと間仕切壁の接合構造２０００が第１の実施の形態と異なる点は、主として連結部材５００の構成である。
接合構造２０００は、第１の実施の形態と同じ構成のデッキプレート１００、間仕切壁３００と、連結部材５００とを備えている。間仕切壁３００がリブ部１２０の延在方向に沿って配設される点は第１の実施の形態と同様である。
【００３４】
連結部材５００は、例えば金属板などから構成され、デッキプレート１００の隣り合う２つのリブ部１２０の間隔よりも大きい幅を有し、かつ、リブ部１２０の延在方向に延在する平坦な底壁５１０と、底壁５１０の幅方向の両側部から起立される２つの側壁５２０とを有している。
２つの側壁５２０は上方に向かうにしたがって互いに近接する方向に傾斜して形成され、これら２つの側壁５２０が２つリブ部１２０のうち幅方向の外側の箇所に係合可能に設けられている。
２つの側壁５２０の上端には幅方向の外側に向けて屈曲された折り返し部５２１が形成され、折り返し部５２１の上面５２２は底壁５１０と平行で平坦な面を形成している。
なお、底壁５１０の上面５１１から側壁５２０の折り返し部５２１の上面５２２までの寸法は、デッキプレート１００のリブ部１２０の高さ以上とし、２つの側壁５２０の間隔は、隣り合うリブ部１２０の間隔の整数倍（本例では１倍）にリブ部１２０の端部１２２の幅を加えた寸法以上とする。また、連結部材５００の長さは、デッキプレート１００のリブ部１２０の延在方向の長さと同程度とする。

連結部材５００は、２つの側壁５２０を上方に向けてその底壁５１０の下面５１２が間仕切壁３００の上端３１０に溶接などによって隙間なく取着されると共に、２つの側壁５２０が２つのリブ部１２０の外側に位置した状態で２つの側壁５２０の折り返し部５２１の上面５２２が板部１１０の下面１１２に溶接などによって隙間なく取着されている。
また、２つのリブ部１２０の下面である平面部１２３に連結部材５００の底壁５１０の上面５１１が例えば接着などによって隙間なく取着されている。
【００３６】
吸音材５３０が、連結部材５００の底壁５１０の上方において、すなわち間仕切壁３００の上方でデッキプレート１００の隣り合う２つのリブ部１２０との間に間仕切壁３００の厚さ方向の全長にわたって、かつ、間仕切壁３００の延在方向にわたって延在するように充填されている。
【００３７】
次に上述したように構成された接合構造２０００の作用効果について説明する。
連結部材５００の２つの側壁５２０の折り返し部５２１の上面５２２が板部１１０の下面１１２に溶接などによって隙間なく取着されている。
また、連結部材５００の底壁５１０の下面５１２は平坦な面として構成されているため、間仕切壁３００の上端３１０およびランナー３０２との間に隙間なく接続することができる。
したがって、均一で優れた遮音性能を実現することができる。
【００３８】
また、デッキプレート１００に接続された連結部材５００に間仕切壁３００を接続する作業は、連結部材５００の下面５１２と間仕切壁３００の上端３１０を接続するのみでよいため、従来に比較して作業が容易である。
また、上記した連結部材５００のデッキプレート１００に対する溶接が全周溶接でもスポット溶接でもよいこと、および、連結部材５００のデッキプレート１００に対する取着が溶接に限定されるものではなく例えば、エアーを用いた打ち付け、金物などによる打ち付けなどを用いることができることは第１の実施の形態の場合と同様である。
また、第２の実施の形態でも、連結部材５００のデッキプレート１００への取着を床スラブ２００の施工後に行なうことができるため、間仕切壁３００を任意の位置に設けることができる利点があることも第１の実施の形態と同じである。
【００３９】
また、上記接合構造２０００によれば、確保すべき遮音性能を、連結部材５００の底壁５１０とデッキプレート１００のリブ部１２０の間に充填する吸音材の有無や、吸音材の量を調整することで容易に変更できる。また、吸音材として多孔質吸音材を使用でき、吸音材の代わりに遮音材、防火材を用いても良いことは第１の実施の形態の場合と同様である。
また、本例では、連結部材５００の２つの側壁５２０の間に位置するデッキプレート１００のリブ部１２０の数を２つとしたが、この数は２以上の複数であってもよい。すなわち、２つの側壁５２０がこれら複数のリブ部１２０のうち幅方向の最も外側に位置する２つのリブ部１２０の外側に位置した状態で２つの側壁５２０がデッキプレート１００の板部１１０の下面１１２に取着すればよい。
このようにして、連結部材５００の側壁５２０の間に位置するリブ部１２０の数を増減することで上記接合構造２０００の遮音性能の程度を容易に変更調整することができる。すなわち、連結部材５００の側壁５２０の間に位置するリブ部１２０の数を増やせば遮音性能が向上され、減らせば遮音性能が減少される。
また、連結部材５００を形成する金属板の厚さによって上記接合構造２０００の遮音性能の程度を変更調整することもできる。
【００４０】
また、この第２の実施の形態の場合では、第１の実施の形態と異なり、連結部材５００がデッキプレート１００を切断したものではない。したがって、例えば床スラブの施工後、時間が経過してからの工事、例えばリフォームなどの場合に、床スラブの施工時のデッキプレート１００の入手が困難であっても連結部材５００を容易に入手して施工することができるという利点もある。
【００４１】
また、連結部材５００の２つの側壁５２０を、これら２つの側壁の間に位置する複数のリブ部１２０のうち幅方向の外側に位置する２つのリブ部１２０の外側の箇所に係合可能に設けることもできる。
この場合には、連結部材５００をデッキプレート１００に容易に仮止めすることができ、作業性を向上させることができる。
【００４２】
図７は、第２の実施の形態で示した接合構造の遮音性能に関する評価結果を示す特性図である。
図７は、図４と同様に、横軸は１／３オクターブ中心周波数、縦軸は音響透過損失をそれぞれ示している。
実験条件は以下に示す４種類の条件である。
（条件１）間仕切壁単体
（条件２）従来の接合構造（デッキプレートのリブ部とランナーとの間にロックウールを充填した）
（条件３）第２の実施の形態の構成に加えて連結部材５００の側壁５２０の外側にモルタルなどを全面的に塗り付けた構成（図７では（本発明▲２▼[塗付全面]）と記載）
（条件４）第２の実施の形態の構成のままであって連結部材５００の側壁５２０の外側にモルタルなどを塗り付けていない構成（図７では（本発明▲２▼[基本]）と記載）
【００４３】
なお、連結部材５００とデッキプレート１００の接続箇所とは、図５で説明すると、連結部材５００の側壁５２０の折り返し部５２１とデッキプレート１００の板部１１０の下面１１２との接続箇所である。また、連結部材５００と間仕切壁３００の接続箇所とは、連結部材５００の底壁５１０の下面５１２と間仕切壁３００の上端３１０との接続箇所である。
【００４４】
図７の実験結果から明らかなように、従来構造に比較して第２の実施の形態の接合構造で遮音性能が向上していることが明らかに示されている。また、（条件３）が最も優れた遮音性能を実現しており、その次に（条件４）が優れていることがわかる。
また、これらの結果から、連結部材５００の側壁５２０の外側にモルタルなどの部材を塗り付けることで遮音性能を向上することができることがわかる。
【００４５】
図７の実験結果についてさらに説明する。
第２の実施の形態の接合構造に対応する条件３と条件４の特性曲線（性能曲線）のうち、周波数が６３０Ｈｚ乃至８００Ｈｚの範囲で音響透過損失の特性が低下している。
この音響透過損失の特性の部分的な低下は、連結部材５００に用いた材料（鉄板）の物性（コインシデンス効果）の影響によるものである。
音響透過損失の特性が低下する周波数範囲は、上記連結部材５００の材質が同一であればその厚さを変更することで周波数範囲をより高い周波数の方向または低い周波数の方向にシフトすることできる。
【００４６】
具体的にいえば、上記連結部材５００の厚さを厚くすることで、音響透過損失の特性が低下する周波数範囲を低い周波数にシフトすることができ、上記連結部材５００の厚さを薄くすることで、音響透過損失の特性が低下する周波数範囲を高い周波数にシフトすることができる。
また、音響透過損失の特性が低下する周波数範囲は、上記連結部材５００の材質を変更することで変えることもできる。
このように連結部材５００の厚さまたは材質を適宜選択することによって、第２の実施の形態の場合にも、第１の実施の形態で示した図４の特性曲線と同等の遮音性能を実現することができる。
【００４７】
図８は本発明のデッキプレートと間仕切壁の接合構造の第３の実施の形態の構成を示す断面図である。
まず、図８を参照して第３の実施の形態の接合構造について説明する。
第３の実施の形態のデッキプレートと間仕切壁の接合構造３０００が第１、第２の実施の形態と異なる点は、複数のデッキプレート１００をリブ部１２０の延在方向と直交する方向に間隔をおいて建物に建て込む点と、複数のデッキプレート１００にコンクリートが打設される前に連結部材６００を各デッキプレート１００の間に配設する点である。間仕切壁３００はリブ部１２０の延在方向に沿って配設される点は第１、第２の実施の形態と同様である。
【００４８】
連結部材６００は、例えば金属板などから構成され、隣り合う２つデッキプレート１００の間で板部１１０よりも下方の位置でリブ部１２０の延在方向に延在する底壁６１０と、底壁６１０の幅方向の両側部から起立される２つの側壁６２０とを有する。底壁６１０は、その幅方向の寸法が間仕切壁３００の厚さ方向の寸法よりも大きくなるように形成されている。また、連結部材６００の長さは、デッキプレート１００のリブ部１２０の延在方向の長さと同程度とする。
２つの側壁６２０の上端には幅方向の外側に向けて屈曲された折り返し部６２１（特許請求の範囲の上端部に相当）が形成され、折り返し部６２１の下面６２２は底壁６１０と平行で平坦な面を形成している。
また、連結部材６００は、それに打設されるコンクリート１０２の側圧に構造的に耐えるとともに、コンクリート１０２が打設された後、耐火性、耐アルカリ性の条件を満たす材質であれば、金属製、木製、合成樹脂製などどのような部材であってもよい。
【００４９】
複数のデッキプレート１００は、リブ部１２０の延在方向と直交する方向に間隔をおいてすなわち隣り合う２つのデッキプレート１００の板部１１０の側縁部１１３の間に帯状の隙間が形成されるように建物に建て込まれる。
連結部材６００は、２つの側壁６２０を上方に向けてその底壁６１０の下面６１２が間仕切壁３００の上端３１０に隙間なく取着されると共に、２つの側壁６２０の折り返し部６２１の下面６２２が隣り合う２つのデッキプレート１００の板部１１０の側縁部１１３に当接して隙間が生じないように配設されている。
すなわち、隣り合う２つのデッキプレート１００の板部１１０の側縁部１１３の間に形成された帯状の隙間が連結部材６００によって閉塞されるようになっている。
【００５０】
この状態で、デッキプレート１００の板部１１０の上面１１１に打設されたコンクリート１０２が、間仕切壁３００の上方で間仕切壁３００の厚さ方向の全長にわたって延在するように、連結部材６００の底壁６１０の上面６１１と２つの側壁６２０に囲まれた部分に充填される。
【００５１】
次に上述したように構成された接合構造３０００の作用効果について説明する。
連結部材６００の２つの側壁６２０の折り返し部６２１の下面６２２は、隣り合う２つのデッキプレート１００の板部１１０の側縁部１１３に当接しており、下面６２２と側縁部１１３との間に隙間が生じないようになっている。
また、連結部材６００の底壁６１０の下面６１２は平坦な面として構成されているため、間仕切壁３００の上端３１０およびランナー３０２との間に隙間なく接続することができる。
したっがって、均一で優れた遮音性能を実現することができる。
また、デッキプレート１００に接続された連結部材６００に間仕切壁３００を接続する作業は、連結部材６００の下面６１２と間仕切壁３００の上端３１０を接続するのみでよいため、従来に比較して作業が容易である。
また、上記接合構造３０００によれば、連結部材６００の底壁６１０の上面６１１と２つの側壁６２０に囲まれた部分に充填されたコンクリート１０２によって優れた遮音性能を実現することができる。
【００５２】
なお、この第３の実施の形態では、デッキプレート１００に対するコンクリートの打設作業の前に連結部材６００をデッキプレート１００に設置することになる。この際、通常は、連結部材６００を隣接するデッキプレート１００の間に置くだけでよい。
ただし、連結部材６００を隣接するデッキプレート１００の間に置くだけでは連結部材６００が安定しない場合など、連結部材６００が配設される場所や状況によっては連結部材６００とデッキプレート１００とを溶接などによって取着する必要がある。
この場合、連結部材６００のデッキプレート１００に対する溶接が全周溶接でもスポット溶接でもよいこと、および、連結部材６００のデッキプレート１００に対する取着は溶接に限定されるものではないことは第１、第２の実施の形態の場合と同様である。
【００５３】
なお、第３の実施の形態における連結部材６００は、第２の実施の形態における連結部材５００と同じ形状とすることができ、この場合には、連結部材を流用することが可能となる。
【００５４】
図９は本発明のデッキプレートと間仕切壁の接合構造の第４の実施の形態の構成を示す断面図、図１０は図９を矢印Ａ方向から見た状態を示す立面図である。図１１（Ａ）は連結部材の一例を示す斜視図、図１１（Ｂ）は連結部材の他の例を示す斜視図である。図１２（Ａ）は連結部材をデッキプレートに取り付ける第１の手順を示す説明図、図１２（Ｂ）は連結部材をデッキプレートに取り付ける第２の手順を示す説明図、図１２（Ｃ）は連結部材をデッキプレートに取り付ける第３の手順を示す説明図である。
【００５５】
まず、図９、図１０を参照して第４の実施の形態の接合構造について説明する。
第４の実施の形態のデッキプレートと間仕切壁の接合構造４０００が第１乃至第３の実施の形態と異なる点は、間仕切壁３００がデッキプレート１００の複数のリブ部１２０の延在方向と直交する方向（交叉する方向）に沿って配設される点と、連結部材７００の構成である。
接合構造４０００は、デッキプレート１００、間仕切壁３００と、連結部材７００とを備えている。
【００５６】
図１１（Ａ）に示されているように、連結部材７００は、例えば金属板から形成され、間仕切壁３００の延在方向に延在する底壁７１０と、底壁７１０の幅方向の両側部から底壁７１０の長手方向に沿って起立された両側の側壁７２０と、各側壁７１０の長手方向に間隔をおいて設けられ上方に開放状の複数の切り欠き７３０とを有して構成されている。側壁７２０は、上部に向かうにしたがって底壁７１０の幅方向内側に傾斜するように構成されている。
底壁７１０の上面７１１と下面７１２は平坦な面を構成している。
側壁７２０の上端部には、底壁７１０の幅方向外側に向かって折り返された折り返し部７２１が底壁７１０と平行な上面７２２を有して設けられている。この上面７２２は、平坦な面を構成し後述するようにデッキプレート１００の板部１１０の下面１１２に取着されるようになっている。
側壁７２０の長手方向の両側部には、底壁７１０の幅方向外側に向かって折り返された折り返し部７２３が設けられている。
後述するように、折り返し部７２３は、側壁７２０の延在方向の向きに折り曲げられることでリブ部１２０との間の隙間を閉塞するようになっている。
【００５７】
次に、図１２（Ａ）乃至図１２（Ｃ）を参照して連結部材７００をデッキプレート１００に接続する手順を説明する。
まず、図１２（Ａ）、図１２（Ｂ）に示されているように、連結部材７００を、その底壁７１０の延在方向が複数のリブ部１２０と直交する方向と一致させ、かつ、連結部材７００の複数の側壁７２０を上方に向け、各切り欠き７３０内に各リブ部１２０が収容されるように位置決めする。
このとき、図９に示されているように、吸音材７４０を間仕切壁３００の上方で間仕切壁３００の厚さ方向の全長にわたって、かつ、間仕切壁３００の延在方向わたって延在するように、両側の側壁７２０と複数のリブ部１２０の間に充填する。
この結果、側壁７２０の上端の折り返し部７２１の上面７２２がデッキプレート１００の板部１１０の下面１１２に面した状態となり、かつ、各リブ部１２０の端部１２２の平面部１２３が底壁７１０の上面７１１に面した状態となる。
【００５８】
この状態では、各側壁７２０の切り欠き７３０と、各切り欠き７３０内に収容された各リブ部１２０との間には間隙がある。
この状態で、図１２（Ｃ）に示されているように、各折り返し部７２３を側壁７２０の延在方向向きに折り曲げることによって各リブ部１２０と切り欠き７３０との間隙が閉塞される。
この際、折り曲げられた各折り返し部７２３の下端部がリブ部１２０の端部１２２の上部に係止することで、連結部材７００はデッキプレート１００に対して仮止めされた状態となる。
【００５９】
図１２（Ｃ）に示された状態で、複数の側壁７２０の折り返し部７２１がデッキプレート１００の板部１１０の下面１１２に溶接などによって隙間なく取着される。
次いで、連結部材７００の底壁７１０の下面７１１が間仕切壁３００の上端３１０に隙間なく取着される。
この結果、図９、図１０に示されているように、連結部材７００は、デッキプレート１００と間仕切壁３００に対して隙間なく取着されて配設される。
【００６０】
次に上述したように構成された接合構造４０００の作用効果について説明する。
連結部材７００の複数の側壁７２０の折り返し部７２１がデッキプレート１００の板部１１０の下面１１２に溶接などによって隙間なく取着される。
また、連結部材７００の底壁７１０の下面７１２は平坦な面として構成されているため、間仕切壁３００の上端３１０およびランナー３０２との間に隙間なく接続することができる。
したがって、均一で優れた遮音性能を実現することができる。
また、デッキプレート１００に接続された連結部材７００に間仕切壁３００を接続する作業は、連結部材７００の下面７１２と間仕切壁３００の上端３１０を接続するのみでよいため、従来に比較して作業が容易である。
また、側壁７２０の折り返し部７２３によって切り欠き７３０と各リブ部１２０との間に隙間が生じないように閉塞されているため、優れた遮音性能を実現することができる。
【００６１】
なお、上記した連結部材７００のデッキプレート１００に対する溶接が、全周溶接でもスポット溶接でもよいこと、および、連結部材７００のデッキプレート１００に対する取着が溶接に限定されるものではなく例えば、エアーを用いた打ち付け、金物などによる打ち付けなどを用いることができることは第１、第２の実施の形態の場合と同様である。
また、第４の実施の形態においても、連結部材７００のデッキプレート１００への取着を床スラブ２００の施工後に行なうことができるため、間仕切壁３００を任意の位置に設けることができる利点があることも第１、第２の実施の形態と同じである。
【００６２】
また、上記接合構造４０００によれば、確保すべき遮音性能を、連結部材７００の底壁７１０とデッキプレート１００のリブ部１２０の間に充填する吸音材の有無や吸音材の量を調整することで容易に変更でき、吸音材として他の多孔質吸音材を使用でき、吸音材の代わりに遮音材、防火材を用いても良いことは第１乃至第３の実施の形態の場合と同様である。
また、本例では、図１１（Ａ）に示されているように、連結部材７００が底壁７１０の幅方向に多数の側壁７２０と切り欠き７３０が設けられたものを使用したが、本発明はこれに限定されるものではなく、図１１（Ｂ）に示されているように、底壁７１０の幅方向にそれぞれ１つの側壁７２０と、それぞれの側壁７２０を挟むように設けられた切り欠き７３０が設けられたものを使用することもできる。
【００６３】
また、連結部材７００の底壁７１０の幅方向の寸法を増減することによって対向する側壁７２０間の間隔を増減させることで上記接合構造４０００の遮音性能の程度を変更調整することができる。
また、連結部材７００を形成する金属板の厚さによって上記接合構造４０００の遮音性能の程度を変更調整することもできる。
なお、連結部材７００の側壁７２０の外側の箇所にコーキングや湿式工法塗り付けを行うことで遮音性能を更に向上させることができる。この際、側壁７２０が上部に向かうほど底壁７１０の幅方向の内側に傾斜した構成としておけば、モルタルなどの塗り付け部材を容易に固定でき、かつ、塗り付け部材が無駄に使用されないのでコスト面で有利である。
【００６４】
また、連結部材７００の底壁７１０の下面７１２にランナー３０２を係合する係合部を設け、ランナー３０２と連結部材７００の取着をより強固にすることも可能である。
また、連結部材７００の底壁７１０にランナー３０２と同じ機能を奏する部材を一体的に設けておけば、間仕切壁３００の上端３１０を連結部材７００に取着する作業をより合理化することができる。
【００６５】
【発明の効果】
以上詳述したように、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、前記複数のリブ部の下方に前記リブ部の延在方向に沿って間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記デッキプレートを該デッキプレートの隣り合う２つのリブ部の間隔よりも大きい幅で切断してなる連結部材を設け、前記連結部材は前記リブ部を上方に向けてその板部の下面が間仕切壁の上端に取着されると共に、前記連結部材のリブ部が前記デッキプレートのリブ部の間に位置し、さらに、前記デッキプレートのリブ部の下面に連結部材の板部の上面が取着されることで配設される構成とした。

また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
吸音材、遮音材、耐火材の少なくとも１つを間仕切壁の上方で間仕切壁の厚さ方向にわたって延在するように、複数のリブ部の間に充填することが可能となる。
【００６９】
また、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、複数個の前記デッキプレートが前記リブ部の延在方向と直交する方向に所定の間隔をおいて建て込まれ、前記隣り合う２つのデッキプレートの間の下方に前記リブ部の延在方向に沿って間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記隣り合う２つのデッキプレートの間で前記板部よりも下方の位置で前記リブ部の延在方向に延在する底壁と、前記底壁の幅方向の両側部から起立される２つの側壁とを有する連結部材を設け、前記連結部材は前記２つの側壁を上方に向けてその底壁の下面が間仕切壁の上端に取着されると共に、前記２つの側壁の上端部が前記隣り合う２つのデッキプレートの板部の側縁部に当接されて配設され、前記デッキプレートの板部の上面に打設されたコンクリートが、前記間仕切壁の上方で間仕切壁の厚さ方向にわたって延在するように、前記連結部材の底壁の上面と前記２つの側壁に囲まれた部分に充填されている構成とした。
【００７０】
そのため、連結部材とデッキプレートの間、連結部材と間仕切壁の上端の間を隙間なく接続することができるため、均一で優れた遮音性能を実現することができる。
また、連結部材を間仕切壁に接続する作業は、連結部材の下面と間仕切壁の上端を接続するのみでよいため、従来に比較して作業が容易である。
また、連結部材の底壁の上面と２つの側壁に囲まれた部分に充填されたコンクリートによって優れた遮音性能を実現することができる。
【００７１】
また、本発明のデッキプレートと間仕切壁の接合構造は、デッキプレートは、コンクリートが打設される上面を有する板部と、該板部の下面に互いに間隔をおき互いに平行に延在する複数のリブ部とを備え、前記複数のリブ部の下方に前記複数のリブ部の延在方向と交叉する方向に延在して間仕切壁が設けられるデッキプレートと間仕切壁の接合構造であって、前記間仕切壁の延在方向に延在する底壁と、前記底壁の幅方向の両側部から前記底壁の長手方向に沿って起立された両側の側壁と、前記各側壁の長手方向に間隔をおいて設けられた上方に開放状の複数の切り欠きとを有する連結部材を設け、前記連結部材は前記複数の側壁を上方に向けてその底壁の下面が間仕切壁の上端に取着されると共に、前記複数の側壁が前記デッキプレートの隣り合う２つのリブ部の間をそれぞれ閉塞するように各リブ部が前記切り欠き内に収容され、かつ、前記複数の側壁の上端部が前記デッキプレートの板部の下面に取着されることで配設される構成とした。

BACKGROUND OF THE INVENTION
The present invention relates to a joining structure of, for example, a deck plate constituting a floor slab and a partition wall provided below the floor slab.
[0002]
[Prior art]
FIG. 13 is a cross-sectional view showing a conventional example of a joining structure of a deck plate and a partition wall, and shows a case where the rib portion of the deck plate and the partition wall are parallel to each other.
A floor slab 200 is configured by placing concrete 102 on the upper surface 111 of the plate portion 110 of the deck plate 100.
The deck plate 100 includes a plurality of rib portions 120 that extend in parallel to each other at a distance from each other on the lower surface 112 of the plate portion 110. The rib portion 120 is configured by a wall portion 121 that is erected from the lower surface 112 of the plate portion 110.
A partition wall 300 is provided below the floor slab 200.
The partition wall 300 and the deck plate 100 are joined by the following procedure.
[0003]
As shown in FIG. 14, a plurality of flat bars 301 extending between the lower portions of two adjacent rib portions 120 are attached to the rib portions 120 at intervals along the extending direction of the rib portions 120. To wear.
A runner 302 made of light iron is hit against the flat bar 301 for attachment. The runner 302 is attached to the floor slab (not shown) below the deck plate 100 by hitting it.
Then, a stat which is a column material extending in the vertical direction is built in the upper and lower runners 302 as a support material, and a plaster board, a calcium silicate plate or the like plate material 303 is nailed on one or both sides of this stat, a staple (tucker) or the like The partition wall 300 is configured by pasting.
Between the plate members 303 constituting the partition wall 300, rock wool or porous sound absorbing material 304 having fire resistance is filled.
Since the runner 302 that fixes the upper portion of the partition wall 300 to the deck plate 100 is often fixed to the lower portion of the rib portion 120, there is a gap between the lower surface 112 of the plate portion 110 of the deck plate 100 and the upper portion of the partition wall 300. There is no sound insulation.
[0004]
Therefore, in order to ensure sound insulation performance, the following measures are necessary to prevent a gap formed between the lower surface 112 of the plate portion 110 of the deck plate 100 and the upper portion of the partition wall 300.
First, after the floor slab 200 is formed, the rib portion 120 of the deck plate 100 is removed by cutting or the like.
Second, a porous sound absorbing material 305 is filled in a space surrounded by the rib portion 120 above the partition wall 300.
Third, the gap is filled by applying or spraying a refractory mortar or the like to the gap formed between the lower surface 112 of the plate portion 110 of the deck plate 100 and the upper portion of the partition wall 300.
[0005]
Further, when the space surrounded by the rib portion 120, the lower surface 102 of the plate portion 100, and the upper surface of the flat bar 301 above the partition wall 300 is filled with the porous sound absorbing material 305 or the like, there are the following problems. .
That is, the height of the rib part 120 is about 60 mm to 100 mm, the interval between the adjacent rib parts 120 is about 200 mm, and the thickness of the partition wall 300 is about 100 mm to 150 mm. Therefore, if the partition wall 300 is to be constructed between the rib portions 120, the construction of the upper portion of the partition wall 300 is difficult because a hand does not enter between the upper portion of the partition wall 300 and the plate portion 110 of the deck plate 100. turn into.
In addition, when the position of the partition wall 300 matches the position of the rib part 120, the partition wall 300 is constructed in the lower part of the rib part 120, and between the upper part of the partition wall 300 and the lower part of the rib part 120. Often it fills the space. In this case, in order to ensure sound insulation performance, it is necessary to take measures against the rib portion 120 at the top of the partition wall 300.
[0006]
15 is a cross-sectional view showing a conventional example of the joining structure of the deck plate and the partition wall, and FIG. 16 is an elevational view showing the state of FIG. 15 as viewed from the direction of arrow A. It shows about the case where a partition wall is orthogonal.
Also in this case, the partition wall 300 is constructed in the same procedure as in FIGS.
At this time, similarly, there is a gap between the lower surface 112 of the plate portion 110 of the deck plate 100 and the upper portion of the partition wall 300, and sound insulation is lacking, so the same measures as described above are required.
Further, as described above, the height of the rib portion 120 is about 60 mm to 100 mm, the interval between the rib portions 120 is about 200 mm, and the thickness in the direction orthogonal to the extending direction of the rib portion at the lower end of the rib portion 120 is about 60 mm. It is normal. For this reason, the space | interval of the substantial rib part 120 will be about 150 mm, and when constructing the partition wall 300 in the lower part of the rib part 120, it is difficult to perform a fine operation | work between the rib part 120 and the upper part of the partition wall 300. FIG.
Further, as a method of filling the gap between the lower surface 112 of the plate portion 110 of the deck plate 100 and the upper portion of the partition wall 300, the partition wall 300 is constructed up to the lower end position of the rib portion 120, and the upper portion of the partition wall 300 and the deck The gap of the lower surface 112 of the plate part 110 of the plate 100 is filled, or as shown in FIG. 16, the upper part of the plate material 303 is cut into a convex shape in accordance with the interval of the rib part 120 to fill the gap and fill the padding. There is also a way to do it.
[0007]
[Problems to be solved by the invention]
However, each of the above-described methods is not only troublesome, but also has a problem that sufficient sound insulation performance cannot be expected, and that the sound insulation performance tends to vary and is difficult to be uniform.
The present invention has been made under the circumstances as described above, and an object of the present invention is to provide a joint structure between a deck plate and a partition wall that can be ensured uniform and excellent sound insulation performance without taking time and effort. .

DETAILED DESCRIPTION OF THE INVENTION
Next, the joining structure of the deck plate and the partition wall according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a configuration of a first embodiment of a joint structure of a deck plate and a partition wall according to the present invention, and FIG. 2 is a perspective view of a connecting member in the first embodiment.
In FIGS. 1 to 12 corresponding to the first to fourth embodiments described below, the same reference numerals as those in FIGS. 13 to 16 are assigned to the same or corresponding parts as those in the conventional bonding structure. The description is omitted.
[0017]
First, the joining structure of the first embodiment will be described with reference to FIGS.
The deck plate / partition wall joining structure 1000 includes a deck plate 100, a partition wall 300, and a connecting member 400. The partition wall 300 is disposed along the extending direction of the rib portion 120.
[0018]
The deck plate 100 includes a plate portion 110 having an upper surface 111 on which concrete 102 is placed, and a plurality of rib portions 120 that are spaced apart from each other and extend in parallel to the lower surface 112 of the plate portion 110.
The rib portion 120 is provided on the opposite side of the wall portion 121 from the lower surface 112 of the plate portion 110 and on the opposite side of the wall portion 121 from the plate portion 110, and is larger in the width direction ( And an end portion 122 having a dimension in a direction perpendicular to the extending direction of the rib portion 120. The end portion 122 is formed with a strip-shaped flat portion 123 that is parallel to the lower surface 112 and has a longitudinal direction in the extending direction of the rib portion 120.
[0019]
The connecting member 400 is configured by cutting the deck plate 100 with a width larger than the interval between two adjacent rib portions 120.
As shown in FIG. 2, the connection member 400 includes a plate portion 410, a wall portion 421 erected from the upper surface 411 of the plate portion 410, and the plate portion 410 of the wall portion 421, as with the deck plate 100. And an end portion 422 having a dimension in the width direction (direction orthogonal to the extending direction of the rib portion 120) larger than the dimension in the thickness direction of the wall portion 421. The end portion 422 is formed with a belt-like plane portion 423 that is parallel to the upper surface 411 and has a longitudinal direction in the extending direction of the rib portion 420.
Further, the upper surface 411 and the lower surface 412 of the plate portion 410 are configured as flat surfaces.
The length of the connecting member 400 is approximately the same as the length of the rib portion 120 of the deck plate 100 in the extending direction.
[0020]
The connecting member 400 has the rib portion 420 facing upward, the lower surface 412 of the plate portion 410 is attached to the upper end 310 of the partition wall 300, and the rib portion 420 of the two adjacent rib portions 120 of the deck plate 100. Further, the upper surface 411 of the plate portion 410 of the connecting member 400 is attached to the flat surface portion 123 that is the lower surface of the two adjacent rib portions 120 of the deck plate 100.
[0021]
Attachment of the lower surface 412 of the plate portion 410 of the connecting member 400 to the upper end 310 of the partition wall 300 and attachment of the upper surface 411 of the plate portion 410 of the connecting member 400 to the flat portion 123 of the two adjacent rib portions 120 of the deck plate 100. The attachment is performed without gaps by welding or the like.
[0022]
Further, the thickness of the partition wall 300 is above the partition wall 300 between the one rib portion 120 of the two adjacent rib portions 120 of the deck plate 100 and the rib portion 420 of the connecting member 400. It is filled so as to extend over the entire length in the vertical direction and over the extending direction of the partition wall 300.
[0023]
Next, the function and effect of the joining structure 1000 configured as described above will be described.
The upper surface 411 of the plate portion 410 of the connecting member 400 is connected to the flat surface portion 123 of the two adjacent rib portions 120 of the deck plate 100 without a gap.
Further, since the lower surface 412 of the plate portion 410 of the connecting member 400 is configured as a flat surface, the lower surface 412 of the plate portion 410 of the connecting member 400 is connected between the upper end 310 of the partition wall 300 and the runner 302 without a gap. can do.
Therefore, uniform and excellent sound insulation performance can be realized.
In addition, the operation of connecting the partition wall 300 to the connecting member 400 connected to the deck plate 100 is only required to connect the lower surface 412 of the connecting member 400 and the upper end 310 of the partition wall 300. Easy.
[0024]
Further, the welding of the connecting member 400 to the deck plate 100 may be all-around welding or spot welding. According to the experiment by the present applicant, it was confirmed that sufficient sound insulation performance can be secured by spot welding.
Further, the attachment of the connecting member 400 to the deck plate 100 is not limited to welding, and for example, driving using air, driving using a hardware, or the like can be used.
Moreover, in 1st Embodiment, since the attachment to the deck plate 100 of the connection member 400 can be performed after construction of the floor slab 200, there exists an advantage which can provide the partition wall 300 in arbitrary positions.
[0025]
Further, in the joining structure 1000 according to the first embodiment, the position where the partition wall 300 is provided with respect to the deck plate 100 is not restricted. Further, the position where the partition wall 300 is provided after the upper floor slab 200 is constructed can be arbitrarily changed.
Further, when a plurality of deck plates 100 are arranged in the extending direction of the rib portions 120, even if there is a positional shift in a direction perpendicular to the extending direction of the rib portions 120 of the adjacent deck plates 100, that is, Even if the rib portions 120 of the adjacent deck plates 100 do not extend linearly, the connecting member 400 can be attached to the deck plate 100 if the rib portions 120 are positioned between the rib portions 420 of the connecting member 400. There are also advantages.
[0026]
Further, according to the joint structure 1000, the presence or absence of the sound absorbing material and the amount of the sound absorbing material to be filled between the rib portion 420 of the connecting member 400 and the rib portion 120 of the deck plate 100 are adjusted. Can be easily changed. As the sound absorbing material, a porous sound absorbing material such as rock wool or glass wool can be used. Moreover, you may use a sound insulation material and a fireproof material instead of a sound absorption material. These sound absorbing materials, sound insulating materials, and fireproofing agents may be either dry or wet.
In this example, the number of the rib portions 420 of the connecting member 400 is two. However, this number may be two or more, and the number of the rib portions 420 of the connecting member 400 may be increased or decreased. The degree of sound insulation performance can be easily changed and adjusted. That is, if the number of the rib parts 420 of the connecting member 400 is increased, the sound insulation performance is improved, and if the number is decreased, the sound insulation performance is reduced.
[0027]
Further, by increasing the number of rib portions 420 of the connecting member 400 to ensure the widthwise dimension of the plate portion 410, the partition wall 300 extends within the range of the widthwise dimension of the lower surface 412 of the plate portion 410. The direction can be set arbitrarily.
For example, the extending direction of the partition wall 300 may have an angle that intersects the extending direction of the rib portion 420. Moreover, the partition wall 300 does not extend linearly, and may be bent or curved.
Furthermore, if the connecting member 400 is disposed so as to cover the entire lower portion of the deck plate 100 constituting the floor slab 200, there is no restriction on the extending direction of the partition wall 300, and the construction direction of the partition wall 300 can be freely set. You can choose.
[0028]
Moreover, according to 1st Embodiment, the same thing as the deck plate 100 which comprises the floor slab 200 as a connection member 400 is cut | disconnected and used. Therefore, since there is no increase in the types of building materials, it is possible to reduce the cost of purchasing parts in bulk, making it unnecessary to change the parts lifting plan, and it is not necessary to separately secure a stock yard (member storage area). In addition, unlike the case where a member for connecting the deck plate 100 and the partition wall 300 is prepared separately, since the number of types of members is small, there is no mistake of misidentifying the member.
[0029]
Next, a case where a deck plate having a tapered shape is used will be described.
FIG. 3 is a side view of a deck plate in which the rib portion is formed in a tapered shape at both ends in the extending direction. The deck plate 100A is configured to approach the lower surface 112 of the plate portion 110 as the end portion 122 of the rib portion 120 extends toward both ends in the extending direction, and finally has a taper shape that matches the lower surface 112. Yes.
This is because both end portions 124 in the extending direction of the rib portion 120 of the deck plate are placed on the upper surface of the beam H of the building.
[0030]
In the deck plate 100A having such a configuration, the connecting member can be configured as follows.
First, similarly to the case of the first embodiment, the deck plate 100A is cut and used as a connecting member. In this case, since a gap is formed at both end portions 124 of both the deck plate 100A constituting the floor slab and the deck plate 100A as the connecting member, the sound insulation performance is somewhat lowered.
Second, the deck plate 100A as the connecting member is cut at an intermediate position in the extending direction of the rib portion 120 (that is, a non-tapered portion). Let the cut | disconnected part be both ends, and let it be a connection member by connecting the edge parts of a taper-shaped part. In this case, since the gap between both end portions 124 of the deck plate 100A constituting the floor slab and the deck plate 100A as the connecting member is closed by the mutual rib portions 120, the sound insulation is higher than in the first case. Less degradation in performance.
Thirdly, the taper portion of the deck plate 100A is cut off and only the non-tapered portion constitutes the connecting member. In this case, since the gap between the two end portions 124 of the deck plate 100A constituting the floor slab is closed by the rib portion 120 of the connecting member, the sound insulation performance can be further reduced as compared with the second case.
[0031]
FIG. 4 is a characteristic diagram showing an evaluation result regarding the sound insulation performance of the joint structure shown in the first embodiment.
In FIG. 4, the horizontal axis indicates the 1/3 octave center frequency, and the vertical axis indicates the sound transmission loss. That is, the sound insulation performance is evaluated by measuring the degree to which the sound generated on one side of the partition wall 300 is transmitted to the other side of the partition wall 300.
The experimental conditions are the following five conditions.
(Condition 1) Single partition wall
(Condition 2) Conventional joining structure (rock wool is filled between the rib portion of the deck plate and the runner)
(Condition 3) In addition to the configuration of the first embodiment, a configuration in which mortar or the like is applied over the entire surface of the connecting member 400 and the rib portion 120 of the deck plate 100 (in FIG. ▲ 1 ▼ [Applying entire surface]))
(Condition 4) In addition to the configuration of the first embodiment, a configuration in which mortar or the like is lightly applied to a portion facing the outside of the connecting member 400 and the rib portion 120 of the deck plate 100 (in FIG. 1 ▼ [Lightly applied]))
(Condition 5) A configuration in which the mortar or the like is not applied to the portion facing the outside of the rib portion 120 of the connecting member 400 and the deck plate 100 as in the configuration of the first embodiment (in FIG. ▲ 1 ▼ [Basic]))
[0032]
As is clear from the experimental results of FIG. 4, it is clearly shown that the sound insulation performance is improved in the joint structure of the first embodiment as compared with the conventional structure. In addition, (Condition 3) realizes the most excellent sound insulation performance, and it can be seen that the sound insulation performance decreases in the order of (Condition 4) and (Condition 5).
In addition, it can be seen from these results that the sound insulation performance can be improved by applying a member such as mortar to a portion facing the outside of the connecting member 400 and the rib portion 120 of the deck plate 100.
[0033]
FIG. 5 is a cross-sectional view showing the configuration of the second embodiment of the joint structure of the deck plate and the partition wall according to the present invention, and FIG. 6 is a perspective view of the connecting member in the second embodiment.
First, the joint structure of the second embodiment will be described with reference to FIGS.
The difference between the deck plate / partition wall joining structure 2000 of the second embodiment and the first embodiment is mainly the configuration of the connecting member 500.
The joining structure 2000 includes the deck plate 100, the partition wall 300, and the connecting member 500 having the same configuration as that of the first embodiment. The point that the partition wall 300 is disposed along the extending direction of the rib portion 120 is the same as that in the first embodiment.
[0034]
The connecting member 500 is made of, for example, a metal plate, has a width larger than the interval between two adjacent rib portions 120 of the deck plate 100, and has a flat bottom extending in the extending direction of the rib portions 120. The wall 510 and two side walls 520 erected from both sides in the width direction of the bottom wall 510 are provided.
The two side walls 520 are formed so as to be inclined toward each other in the upward direction, and these two side walls 520 are provided so as to be able to engage with the outer portions in the width direction of the two rib portions 120.
A folded portion 521 that is bent outward in the width direction is formed at the upper ends of the two side walls 520, and an upper surface 522 of the folded portion 521 forms a flat surface parallel to the bottom wall 510.
The dimension from the upper surface 511 of the bottom wall 510 to the upper surface 522 of the folded portion 521 of the side wall 520 is equal to or greater than the height of the rib portion 120 of the deck plate 100, and the interval between the two side walls 520 is between the adjacent rib portions 120. The dimension is equal to or larger than the integral multiple of the interval (1 in this example) plus the width of the end 122 of the rib 120. The length of the connecting member 500 is approximately the same as the length of the rib portion 120 of the deck plate 100 in the extending direction.
[0035]
The connecting member 500 has two side walls 520 facing upward, and the lower surface 512 of the bottom wall 510 is attached to the upper end 310 of the partition wall 300 without a gap by welding or the like, and the two side walls 520 have two rib portions 120. The upper surface 522 of the folded-back portion 521 of the two side walls 520 is attached to the lower surface 112 of the plate portion 110 without any gap by welding or the like.
Further, the upper surface 511 of the bottom wall 510 of the connecting member 500 is attached to the flat surface portion 123 which is the lower surface of the two rib portions 120 without any gaps, for example, by adhesion.
[0036]
The sound absorbing material 530 extends over the entire length in the thickness direction of the partition wall 300 above the bottom wall 510 of the connecting member 500, that is, between the two adjacent rib portions 120 of the deck plate 100 above the partition wall 300, and The partition wall 300 is filled so as to extend in the extending direction.
[0037]
Next, the function and effect of the joint structure 2000 configured as described above will be described.
The upper surface 522 of the folded portion 521 of the two side walls 520 of the connecting member 500 is attached to the lower surface 112 of the plate portion 110 with no gaps by welding or the like.
Further, since the lower surface 512 of the bottom wall 510 of the connecting member 500 is configured as a flat surface, it can be connected between the upper end 310 of the partition wall 300 and the runner 302 without a gap.
Therefore, uniform and excellent sound insulation performance can be realized.
[0038]
Further, the operation of connecting the partition wall 300 to the connecting member 500 connected to the deck plate 100 is only to connect the lower surface 512 of the connecting member 500 and the upper end 310 of the partition wall 300, so that the operation is performed in comparison with the conventional case. Easy.
Further, the welding of the connecting member 500 to the deck plate 100 may be all-around welding or spot welding, and the attachment of the connecting member 500 to the deck plate 100 is not limited to welding. For example, air is used. As in the case of the first embodiment, it is possible to use hitting, hitting with hardware, and the like.
Also in the second embodiment, since the attachment of the connecting member 500 to the deck plate 100 can be performed after the construction of the floor slab 200, there is an advantage that the partition wall 300 can be provided at an arbitrary position. Is the same as that of the first embodiment.
[0039]
Further, according to the joint structure 2000, the presence or absence of a sound absorbing material that fills the sound insulation performance to be ensured between the bottom wall 510 of the connecting member 500 and the rib portion 120 of the deck plate 100 and the amount of the sound absorbing material are adjusted. Can be easily changed. Further, as in the case of the first embodiment, a porous sound absorbing material can be used as the sound absorbing material, and a sound insulating material and a fireproof material may be used instead of the sound absorbing material.
In this example, the number of the rib portions 120 of the deck plate 100 positioned between the two side walls 520 of the connecting member 500 is two, but the number may be two or more. That is, the two side walls 520 are positioned outside the two rib portions 120 that are positioned on the outermost side in the width direction among the plurality of rib portions 120, and the two side walls 520 are the lower surfaces 112 of the plate portions 110 of the deck plate 100. Just attach it to
In this way, the degree of the sound insulation performance of the joint structure 2000 can be easily changed and adjusted by increasing or decreasing the number of rib portions 120 positioned between the side walls 520 of the connecting member 500. That is, if the number of rib portions 120 positioned between the side walls 520 of the connecting member 500 is increased, the sound insulation performance is improved, and if the number is decreased, the sound insulation performance is reduced.
Further, the degree of the sound insulation performance of the joint structure 2000 can be changed and adjusted according to the thickness of the metal plate forming the connecting member 500.
[0040]
In the case of the second embodiment, unlike the first embodiment, the connecting member 500 does not cut the deck plate 100. Therefore, for example, in the case of construction after the passage of time after construction of the floor slab, such as renovation, the connecting member 500 is easily obtained even if it is difficult to obtain the deck plate 100 at the time of construction of the floor slab. There is also an advantage that it can be installed.
[0041]
Further, the two side walls 520 of the connecting member 500 are provided so as to be able to engage with the outer portions of the two rib portions 120 positioned on the outer side in the width direction among the plurality of rib portions 120 positioned between the two side walls. You can also.
In this case, the connecting member 500 can be easily temporarily fixed to the deck plate 100, and workability can be improved.

FIG. 7 is a characteristic diagram showing an evaluation result regarding the sound insulation performance of the joint structure shown in the second embodiment.
In FIG. 7, as in FIG. 4, the horizontal axis indicates the 1/3 octave center frequency, and the vertical axis indicates the sound transmission loss.
The experimental conditions are the following four conditions.
(Condition 1) Single partition wall
(Condition 2) Conventional joining structure (rock wool is filled between the rib portion of the deck plate and the runner)
(Condition 3) In addition to the configuration of the second embodiment, a configuration in which mortar or the like is entirely applied to the outside of the side wall 520 of the connecting member 500 (in FIG. 7, (invention (2) [entire application surface]) Described)
(Condition 4) The configuration of the second embodiment is maintained and a configuration in which mortar or the like is not applied to the outside of the side wall 520 of the connecting member 500 (in FIG. 7, (the present invention (2) [basic]) is described. )
[0043]
In addition, the connection location of the connection member 500 and the deck plate 100 is a connection location of the folding | returning part 521 of the side wall 520 of the connection member 500, and the lower surface 112 of the board part 110 of the deck plate 100, if demonstrated in FIG. Further, the connection location between the connecting member 500 and the partition wall 300 is a connection location between the lower surface 512 of the bottom wall 510 of the connection member 500 and the upper end 310 of the partition wall 300.
[0044]
As is clear from the experimental results of FIG. 7, it is clearly shown that the sound insulation performance is improved in the joint structure of the second embodiment as compared with the conventional structure. It can also be seen that (Condition 3) achieves the best sound insulation performance, and then (Condition 4) is excellent.
Also, it can be seen from these results that the sound insulation performance can be improved by applying a member such as mortar to the outside of the side wall 520 of the connecting member 500.
[0045]
The experimental results in FIG. 7 will be further described.
Among the characteristic curves (performance curves) of Condition 3 and Condition 4 corresponding to the joint structure of the second embodiment, the characteristic of sound transmission loss is reduced in the frequency range of 630 Hz to 800 Hz.
This partial reduction in the characteristics of the sound transmission loss is due to the influence of the physical properties (coincidence effect) of the material (iron plate) used for the connecting member 500.
If the material of the connection member 500 is the same, the frequency range in which the sound transmission loss characteristic is lowered can be shifted to a higher frequency direction or a lower frequency direction by changing the thickness thereof.
[0046]
Specifically, by increasing the thickness of the connecting member 500, it is possible to shift the frequency range in which the characteristic of sound transmission loss is lowered to a lower frequency, and reducing the thickness of the connecting member 500. Thus, the frequency range in which the characteristic of sound transmission loss is lowered can be shifted to a higher frequency.
Further, the frequency range in which the characteristic of sound transmission loss is lowered can be changed by changing the material of the connecting member 500.
By appropriately selecting the thickness or material of the connecting member 500 as described above, the sound insulation performance equivalent to the characteristic curve shown in FIG. 4 shown in the first embodiment is realized even in the case of the second embodiment. can do.

The difference between the deck plate / partition wall joining structure 3000 of the third embodiment and the first and second embodiments is that the plurality of deck plates 100 are spaced in a direction perpendicular to the extending direction of the ribs 120. In other words, the connecting member 600 is disposed between the deck plates 100 before the concrete is placed on the plurality of deck plates 100. The partition wall 300 is the same as the first and second embodiments in that it is disposed along the extending direction of the rib portion 120.
[0048]
The connecting member 600 is made of, for example, a metal plate, and has a bottom wall 610 extending in the extending direction of the rib portion 120 at a position below the plate portion 110 between two adjacent deck plates 100, and a bottom wall. 610 and two side walls 620 erected from both sides in the width direction.
