Description

【０００１】
【発明の属する技術分野】
本発明は、建物の内装構造に係る。特に防振構造、制振構造、または遮音構造に特徴の有る固体音防止型の建物の浮き内装構造に関する。
【０００２】
【従来の技術】
今後、高層マンション等の高層ビルの建設が都心を中心に計画されている。建物が高層になるにしたがい、軽量で遮音性能の高い隔壁又は戸境壁が必要とされる。また、人々の音に対する関心が高まるにつれ、隣接部屋同士や上下階の室間遮音がますます重要になってきている。
遮音性能は質量則にしたがって向上するといわれている。すなわち、単位面積当たりの重量が増すほど、遮音性能があがると言われているが、実際には、質量が増えても十分な遮音性能が得られていない。その原因の一つは、振動が壁材に入射して壁表面から固体音が放射されるためである。従って、壁の施工時に、基礎と壁材に入射する振動をいかに遮断するかが大きなポイントになる。
【０００３】
従来の建物の内装構造は、上記目的を達成するために、
１，基礎と壁の二重構造とする。
２，基礎と壁の間に胴ふちを設ける。
３，基礎と壁の間に空隙を設ける。
４，基礎と壁の間に設ける胴ふちの構造を工夫する。
等の工夫をしていた。
【０００４】
ところで、発明者は、特公平７−３５８３８において、「ほぼ椀状をなす本体を粘弾性材料で形成し、該本体開口側端縁に鍔状展出部を設け、該鍔状展出部の対象物に対向する面に環状の突起を設け該対象物に接触し本体内部をほぼ気密構造とし、該本体の肉厚を前記鍔状展出部から頂部に向け減少させ、荷重により前記本体との接触面積が変化する荷重板部材を前記本体の頂部に接触位置させてなる防振装置」を開示している。
その防振装置は、その構造により固体音に関連する振動に対し優れた防振性能を発揮する。
【０００５】
【発明が解決しようとする課題】
建物の内装構造の場合、床基礎、壁基礎、天井基礎等の基礎から壁、床、天井に振動が伝わり、壁、床、天井の壁材、床材、天井材が振動することによって、壁、床、天井の面から固体音が放射する。また、床基礎、壁基礎、天井基礎等の基礎から透過してくる音および表面から放射された音が部屋の内部に進入する。従来の建物浮き内装構造では今以上にこれらの音の放射、進入を防止することができなかった。
従って、今以上に、隣接部屋間の遮音性能と、上下階の部屋間の遮音性能を、向上できないという問題があった。
【０００６】
本発明は以上に述べた問題点に鑑み案出されたもので、従来の壁と床と天井とで構成される部屋の壁基礎、床基礎、又は天井基礎である基礎の内側に設けられる建物浮き内装構造にかわって、隣接部屋間の遮音性能または上下階の部屋間の遮音性能を向上させた建物浮き内装構造を提供しようとする。
【０００７】
【課題を解決するための手段】
上記目的を達成するため、本発明に係る壁と床と天井とで構成される部屋の壁基礎、床基礎、又は天井基礎である基礎の内側に設けられる建物浮き内装構造は、内側表面が壁、床、又は天井のうちの少なくともひとつを形成する様に相互に隙間を空けて並べられた複数の板材と、前記複数の板材を支持する粘弾性支持部材を有し基礎に固定された板材支持構造と、前記板材の前記隙間に充填された粘弾性材料製の板材隙間充填材と、を備えたものとした。
また、裏込め材が前記板材の隙間にはめ込まれていてもよい。
また、前記板材の隙間に突起部があってもよい。
また、前記粘弾性支持部材が、ほぼ椀状をなす本体を粘弾性材料で形成し、該本体の開口側端縁に鍔状展出部を設け、該鍔状展出部の対象物に対向する面に環状の突起を設け該対象物に接触し該本体の内部をほぼ気密構造とし、該本体の肉厚を前記鍔状展出部から頂部に向けて減少させたものであって、該頂部で前記板材を支持してもよい。
また、裏込め材としての樹脂製ロープ材が前記板材の隙間の基礎に対面する側にはめ込まれていてもよい。
また、前記板材の隙間の基礎に対面する側に突起部があってもよい。
また、前記板材隙間充填材が板材の隙間の空間の該裏込め材または該突起部を除く空間に空隙が残らない様に充填されてもよい。
【０００８】
上記本発明の構成により、相互に隙間を空けて並べられた複数の板材の内側表面が壁、床、又は天井を形成し、基礎に固定された板材支持構造の粘弾性支持部材が前記複数の板材を支持し、粘弾性材料製の板材隙間充填材が前記板材の前記隙間に充填されるので、
基礎からの振動が板材に伝搬しにくく、基礎からの空気伝搬音が板材と板材の境目から部屋の内部に進入しにくく、板材隙間充填材が隣り合った板材の振動を減衰させるので、基礎、床基礎、又は天井基礎である基礎からの振動が壁、床、または天井に伝搬することを抑制し、固体音の発生が抑制され、その結果部屋の内部に放射される音の遮蔽効果を増大させる。
【０００９】
さらに、本発明に係る建物浮き内装構造は、壁基礎の内周に沿って壁基礎から離れて床基礎の上部に配置される際根太上部板と、前記際根太上部板を下から支持する粘弾性支持部材を有し前記床基礎に置かれた際根太支持構造とを備え、床を形成する床板材の最外周部が際根太上部板の上部に乗せられたものとした。
上記本発明の構成により、際根太上部板が壁基礎の内周に沿って前記壁基礎から離れて床基礎の上部に配置され、前記床基礎に置かれた際根太支持構造の粘弾性支持部材が前記際根太上部板を下から支持し、床を形成する床板材の最外周部が際根太上部板の上部に乗せられるので、
壁基礎の振動が際根太上部板を介して床に伝搬することがなく、床基礎の振動が際根太上部板を介して床への伝搬することが粘弾性支持部材により抑制され、壁基礎と床基礎の振動が部屋の内部に進入するのを抑制でき、振動が基礎から部屋の内部部材に伝搬しにくくなる。
【００１０】
さらに、本発明に係る建物浮き内装構造は、壁を形成する前記板材の最下部が床基礎から離れており、床を形成する前記板材の最外周部が壁基礎から離れており、壁を形成する前記板材の最下部と床を形成する前記板材の最外周部との間に壁床間隙間があり、前記壁床間隙間に充填された粘弾性材料製の壁床隙間充填材を備えるものとした。
上記本発明の構成により、壁を形成する前記板材の最下部と床基礎との間に空隙があり、床を形成する前記板材の最外周部と壁基礎との間に空隙があり、壁を形成する前記板材の最下部と床を形成する前記板材の最外周部との間に壁床間隙間があり、粘弾性材料製の壁床隙間充填材がその壁床間隙間に充填されるので、基礎の振動により放射された音が壁または床を加振した際に、境の壁床隙間充填材が板材の振動を減衰させて固体音の放射を抑制でき、又壁基礎または床基礎の表面から放射された音が、壁と床との境から漏れて室内に入ることを防止し、壁基礎と床基礎の表面から放射した音が部屋の内部に進入するのをさらに抑制できる。
【００１１】
さらに、本発明に係る建物浮き内装構造は、壁を形成する前記板材の最上部が天井基礎から離れており、天井を形成する前記板材の最外周部が壁基礎から離れており、壁を形成する前記板材の最上部と天井を形成する前記板材の最外周部との間に壁天井間隙間があり、前記壁天井間隙間に充填された粘弾性材料製の壁天井隙間充填材を備えるものとした。
上記本発明の構成により、壁を形成する前記板材の最下部と天井基礎との間に空隙があり、天井を形成する前記板材の最外周部と壁基礎との間に空隙があり、壁を形成する前記板材の最上部と天井を形成する前記板材の最外周部との間に壁天井間隙間があり、粘弾性材料製の壁天井隙間充填材がその壁天井間隙間に充填されるので、
基礎の振動により放射された音が壁または天井を加振した際に、境の壁天井隙間充填材が板材の振動を減衰させて固体音の放射を抑制でき、又壁基礎または天井基礎の表面から放射された音が、壁と天井との境から漏れて室内に入ることを防止でき、壁基礎と天井基礎の表面から放射した音が部屋の内部に進入するのをより抑制できる。
【００１２】
上記目的を達成するため、本発明に係る壁と床とで構成される部屋の壁基礎、又は床基礎である基礎の内側に設けられる建物浮き内装構造は、壁基礎の内周に沿って壁基礎から間に空隙を挟んで離れて床基礎の上部に配置される根太である際根太上部板と、前記際根太上部板を下から支持する粘弾性支持部材を有し前記床基礎に置かれた際根太支持構造と、前記際根太上部板の上部に置かれた床を形成する板材と、を備えたものとした。
また、前記際根太支持構造が壁基礎から間に空隙を挟んで離れて配置されてもよい。
さらに、前記際根太上部板の上部に置かれた床を形成する様に並べられた複数の板材と、前記複数の板材を支持する粘弾性支持部材を有し前記床基礎に固定された板材支持構造と、を備えてもよい。
また、前記粘弾性支持部材が、ほぼ椀状をなす本体を粘弾性材料で形成し、該本体の開口側端縁に鍔状展出部を設け、該鍔状展出部の対象物に対向する面に環状の突起を設け該対象物に接触し該本体の内部をほぼ気密構造とし、該本体の肉厚を前記鍔状展出部から頂部に向けて減少させたものであって、前記頂部が際根太上部板または前記板材を支持してもよい。
【００１３】
上記本発明の構成により、際根太上部板が、床基礎の上部に壁基礎の内周に沿って配置され、壁基礎から離れており、床基礎に置かれた際根太支持構造の粘弾性支持部材が前記際根太上部板を下から支持し、床を形成する板材が前記際根太上部板の上部に置かれるので、
壁基礎の振動が際根太上部板を介して床に伝搬することがなく、床基礎の振動が際根太上部板を介して床への伝搬することが粘弾性支持部材により抑制され、壁基礎と床基礎の振動が部屋の内部に進入するのを抑制できる。
【００１４】

【００１７】
板材１０，２０，３０は、内側表面が壁３、床４、又は天井５を形成する部材であり、壁板材１０、床板材２０、および天井板材３０である。
複数の壁板材１０が、相互に隙間を空けて並べられて、一面の壁３を構成する。複数の床板材２０が、相互に隙間を空けて並べられて、一面の床４を構成する。複数の天井板材３０が、相互に隙間を空けて並べられて、一面の天井５を構成する。その隙間は、粘弾性材料を充填する際の施工の容易のために、１ｍｍから５ｍｍの間であるのが好ましい。

【００１８】
板材支持構造４０，５０，６０は、前記複数の板材を支持する粘弾性支持部材４１，５１，６１を有し基礎に固定された構造であり、壁板材支持構造４０、床板材支持構造５０、および天井板材支持構造６０である。
【００１９】
壁板材支持構造４０は、複数の壁板材１０を支持する粘弾性支持部材を有し基礎に固定された構造であり、粘弾性支持部材４１と壁基礎金具４２と粘弾性支持部材保持金具４３と壁支持金具４４とを有する。
粘弾性支持部材４１は、複数の壁板材を支持する部材であり、ゴム等の粘弾性素材でできた部材である。さらに、粘弾性支持部材４１は、特公平７−３５８３８で開示された「防振装置の本体」であるのが好ましい。
壁基礎金具４２は、後述する粘弾性支持部材保持金具４３が嵌合する溝を設けられた部屋の壁の高さに略等しい長さをもったレール状金具である。壁基礎金具４２は、長手方向を垂直にして壁基礎６にネジ止めまたは接着剤で固定される。
粘弾性支持部材保持金具４３は、壁基礎金具４２の溝に嵌合する鍔状部と粘弾性支持部材４１の一部（防振装置の本体の鍔部）を引っかける爪部を設けられた部材である。一個の粘弾性支持部材保持金具４３は、一個の粘弾性支持部材４１を爪部で引っかけて保持する。
壁支持金具４４は、壁板材１０の高さ寸法より僅かに短い長尺部材（例えば、野縁）であり、壁板材１０をネジ止めまたは接着剤で固定し、粘弾性支持部材４１に固定される。２本から数本の壁支持金具４４が一枚の壁部材１０を支持する。壁支持金具４４は、粘弾性支持部材４１の一部（防振装置の本体の頂部）に固定される。
さらに、振動の減衰効果には、壁支持金具４４と板材１０との間に粘弾性材料製（例えば、ゴム等）の板材４５を挟むのが好ましい。
粘弾性支持部材４１と壁支持金具４４とが、壁板材１０を支持するので、各々の壁板材１０は各々自由に振動できる。
【００２０】
床板材支持構造５０は、複数の床板材２０を支持する粘弾性支持部材５１を有し床基礎７に置かれた構造であり、粘弾性支持部材５１と荷重板部材５２と床支持部材５３と床支持部材固定軸５４とを有する。

荷重板部材５２は、開口部を下向きにした皿状金具であり、粘弾性支持部材５１（防振装置）の上部に固定される。粘弾性支持部材５１が防振装置の本体である場合、静荷重が作用すると防振装置の本体を押しつぶして振動系のばね定数を変化させて、最適な固有振動数にする作用を有する。
床支持部材５３は、略四角形の板であり、後述する床支持部材固定軸５４の上端に固定される。

粘弾性支持部材５１と荷重板部材５２と床支持部材５３と床支持部材固定軸５４とが複数の床板材２０を各々独立に支持するので、各々の床板材２０は各々自由に振動できる。
【００２１】
天井板材支持構造６０は、複数の天井板材３０を支持する粘弾性支持部材６１を有し天井基礎８の下面に固定された構造であり、粘弾性支持部材６１と天井基礎金具６２と天井壁支持軸６３と天井支持金具６４と天井荷重板部材６５とを有する。

天井支持金具６４は、天井板材３０の幅寸法より僅かに短い長尺部材（例えば、野縁）であり、天井板材１０をネジ止めまたは接着剤で固定し、天井壁支持軸６３の下端に固定される。２本から数本の天井支持金具６３が一枚の天井部材３０を支持する。
さらに、振動の減衰効果には、天井支持金具６４と板材３０との間に粘弾性材料製（例えば、ゴム等）の板材６６を挟むのが好ましい。
粘弾性支持部材６１と天井壁支持軸６３と天井支持金具６４とが、天井板材３０を各々独立に支持するので、各々の天井板材３０は各々自由に振動できる。
【００２２】
板材隙間充填材１１，２１，３１は、板材の前記隙間に充填された粘弾性材料製の充填材であり、壁板材隙間充填材１１，床板材隙間充填材１２および天井板材隙間充填材１３である。
板材の隙間の２つの形式の様子を図８（Ａ）、（Ｂ）を参照して詳述する。図８（Ａ）、（Ｂ）は、壁紙１４，床フローリング（または、絨毯）２４，天井紙３４が、壁１０、床２０、または天井３０の表面に施された状態を示している。
板材の隙間とは、壁板材の相互の隙間、床板材相互の隙間、および天井板材相互の隙間をいう。
最初に、図８（Ａ）に基づいて説明する。
裏込め材１２，２２，３２が、板材１０，２０，３０の隙間の裏側（基礎に対面する側をいう）にはめ込まれている。裏込め材１２，２２，３２は、例えば、発泡ウレタン製のロープである。
板材隙間充填材１１，２１，３１が、板材の隙間の空間の樹脂製ロープ材を除く空間に空隙が残らない様に充填されている。
石膏パテ１３，２３，３３が、壁、床または天井の表面に凸凹ができない様に一様に薄く塗られている。
壁紙１４，床フローリング（または、絨毯）２４，天井紙３４が、壁３，床４または天井５の表面になるように施工されている。
【００２３】
次に、図８（Ｂ）に基づいて説明する。図８（Ａ）のものと比較して裏込め材１２，２２，３２がなく、板材１０，２０，３０の隙間の裏側（基礎に対面する側をいう）に突起部１５、２５、３５があることが異なり、その他を同じである。この突起部１５、２５、３５は、板材の外周に一様に設けられていてもよいし、所定の間隔ごとに設けられいてもよい。
【００２４】
際根太上部板７０は、壁基礎６の内周に沿って壁基礎６から離れて床基礎の上部に配置される根太である。際根太上部板７０は、長尺の板材であり、板面を上下に向け、板幅方向の縁が壁基礎６に接触しない様に、部屋を構成する壁基礎６の内周に沿って設けられる。際根太上部板７０は、後述する際根太支持構造８０に支持される。
床４の縁部分を構成する床板材２０の外周部が、際根太上部板７０に乗っている。
さらに、振動の減衰効果及び人の体重が際根太上部板にかかった際に生ずるきしみ音を除去するには、際根太上部板７０と板材２０との間に粘弾性材料製（例えば、ゴム等）の板材７１を挟むのが好ましい。
【００２５】
際根太支持構造８０は、前記際根太上部板７０を下から支持する粘弾性支持部材８１を有し前記床基礎に置かれた構造である。粘弾性支持部材８１は、特公平７−３５８３８で開示された防振装置であるのが好ましい。粘弾性支持部材８１は、その下部（防振装置の鍔状展出部の下面）を床基礎の上面に置かれ、その上部（防振装置の頂部）により際根太上部板７０の下面を保持する。
際根太上部板７０に作用する荷重の大きさにより、粘弾性支持部材８１の数を決定する。粘弾性支持部材８１の数が多くなれば、際根太支持構造８０全体のばね定数は大きくなり、荷重による沈み込みが少なくなる。
粘弾性支持部材８１として防振装置を採用した場合、際根太上部板７０が特公平７−３５８３８における防振装置の荷重板部材に相当する。
【００２６】
壁壁隙間充填材９０は、粘弾性材料でできており、壁３を形成する壁板材１０の左右端とその壁３に交差する他の壁３を形成する他の壁板材１０の面との間の隙間に充填される。
壁床隙間充填材９１は、粘弾性材料でできており、壁３を形成する壁板材１０の最下部と床４を形成する床板材２０の上面との間の隙間に充填される。
壁天井隙間充填材９２は、粘弾性材料でできており、壁３を形成する壁板材１０の最上部と天井５を形成する天井板材３０の下面との間の隙間に充填される。
壁壁隙間充填材９０、壁床隙間充填材９１、または壁天井隙間充填材９２が充填される隙間の様子は、板材隙間充填材１１，２１，３１が充填される隙間と同様なので、説明を省略する。
【００２７】
次に、本発明の実施形態に係る壁３と床４と天井５とで構成される部屋２の壁基礎６、床基礎７、又は天井基礎８である基礎６，７，８の内側に設けられる建物浮き内装構造１の作用を説明する。
上下の階や隣接する部屋等から伝搬してきた壁基礎６、床基礎７、又は天井基礎８である基礎の振動が部屋２の内部への進入する様子を、固体音と空気伝搬音とに分けて説明する。
ここで、固体音とは、基礎６，７，８と板材１０，２０，３０の固体中を伝搬して最終的に板材の表面から部屋２の内部に放射される音である。空気伝搬音とは、基礎６，７，８の表面から放射して、空気中を伝搬して、部屋２の内部に進入する音である。
【００２８】
最初に、固体音の伝搬について説明する。
壁基礎６、床基礎７、又は天井基礎８等の基礎６，７，８に伝わってきた振動は、壁板材支持構造４０、床板材支持構造５０、又は天井板材支持構造６０を介して、壁板材１０、床板材２０、または天井板材３０等の板材に伝搬しようとする。
板材支持構造４０，５０，６０と板材１０、２０、３０とで構成される振動系の固有振動数を適当に調整することにより、基礎６，７，８から板材１０、２０、３０へ伝搬する固体音を抑制できる。特に板材支持構造４０，５０，６０に前記の防振装置を採用していると、上記の固有振動数の調整が容易にでき、固体音の伝搬の抑制が容易になる。
粘弾性支持部材が、複数の板材２０、３０、４０を支持するので、固体音を有効に減衰させる。
粘弾性支持部材が、複数の板材２０、３０、４０を支持し、複数の板材２０、３０、４０の間に隙間があるので、板材相互間での固体音の伝搬がなく、何らかの原因で一枚の板材に伝搬した振動が他の板材へ伝搬するのを防止できる。
複数の板材相互の隙間に粘弾性材料製の板材隙間充填材が充填されているので、板材隙間充填材が板材の振動エネルギーを吸収し減衰する。
【００２９】
次に、空気伝搬音の放射について説明する。
壁基礎６、床基礎７、又は天井基礎８の基礎６，７，８に伝わってきた振動により、基礎６，７，８の表面から放射される音（音圧エネルギー）が基礎６，７，８と板材１０，２０，３０との隙間に充満する。
壁板材１０相互の隙間、床板材２０相互の隙間、および天井板材３０相互の隙間に、粘弾性材料製の板材隙間充填材が充填されているので、空気伝搬音が隣り合う板材と板材の境を通過して部屋２の内部に漏れることがない。
壁と床、壁と壁、及び壁と天井の隙間に粘弾性材料製の板材隙間充填材が充填されているので、空気伝搬音が隣り合う壁と床、壁と壁、及び壁と天井の境を通過して部屋２の内部に漏れることがない。
板材の端部と基礎の間が空いているので、壁基礎６の表面から放射した空気伝搬音は、床基礎７と床板材２０との隙間又は天井基礎８と天井板材３０との隙間に回り込み、音のエネルギーが分散され、振動が抑制される。また、床基礎７の表面から放射した空気伝搬音は、壁基礎６と壁板材１０との隙間に回り込み、音のエネルギーが分散され、振動が抑制される。また、天井基礎８の表面から放射した空気伝搬音エネルギーは、壁基礎６と壁板材１０との隙間に回り込み、音のエネルギーが分散され、振動が抑制される。
また、壁基礎６の表面から放射した空気伝搬音エネルギーが再度、壁板を振動させて固体音となった場合は、壁板相互の振動抑制効果により、振動を抑制する。
【００３０】
上述の実施形態の壁と床と天井とで構成される部屋の壁基礎、床基礎、又は天井基礎である基礎の内側に設けられる建物浮き内装構造を用いれば、板材支持構造と板材とで構成される振動系の固有振動数を適当に調整することにより、基礎から板材へ伝搬する固体音を抑制できる。
また、板材支持構造に防振装置を採用しているので、固体音に関連する振動成分を効率良く減衰させ、固体音の発生を容易に防止できる。
また、粘弾性支持部材が、複数の板材の周辺を固定し、振動減衰させるので、固体音を有効に減衰できる。

The present invention relates to an interior structure of a building. More particularly, the present invention relates to a floating interior structure of a solid sound prevention type building characterized by a vibration isolation structure, a vibration suppression structure, or a sound insulation structure.
[0002]
[Prior art]
In the future, the construction of high-rise buildings such as high-rise apartments is planned mainly in the city center. As the building becomes taller, a light-weight and sound-insulating partition wall or door wall is required. As people's interest in sound increases, sound insulation between adjacent rooms and between rooms on the upper and lower floors is becoming increasingly important.
Sound insulation performance is said to improve according to the mass law. That is, it is said that the sound insulation performance increases as the weight per unit area increases, but actually, sufficient sound insulation performance is not obtained even if the mass increases. One of the causes is that vibrations enter the wall material and solid sound is radiated from the wall surface. Therefore, how to cut off the vibrations incident on the foundation and wall material is important when constructing walls.
[0003]
In order to achieve the above purpose, the interior structure of a conventional building
1. A double structure with a foundation and a wall.
2. Establish a torso between the foundation and the wall.

The wallpaper 14, the floor flooring (or carpet) 24, and the ceiling paper 34 are constructed so as to be the surface of the wall 3, the floor 4, or the ceiling 5.
[0023]
Next, a description will be given based on FIG. Compared with the thing of FIG. 8 (A), there is no backfilling material 12,22,32, and the projection parts 15,25,35 are on the back side (it says the side which faces a foundation) of the clearance gap between board | plate materials 10,20,30. There are different things and the others are the same. The protrusions 15, 25, and 35 may be provided uniformly on the outer periphery of the plate material or may be provided at predetermined intervals.
[0024]
The edge joist upper plate 70 is a joist that is disposed on the floor foundation apart from the wall foundation 6 along the inner periphery of the wall foundation 6. The border joist upper plate 70 is a long plate material, and is provided along the inner periphery of the wall foundation 6 constituting the room so that the plate surface faces up and down and the edge in the plate width direction does not contact the wall foundation 6. It is done. The outer joist upper plate 70 is supported by an outer joist support structure 80 described later.
The outer peripheral part of the floor board material 20 constituting the edge part of the floor 4 is on the joist upper board 70.
Furthermore, in order to remove the vibration damping effect and the squeak noise that occurs when the weight of a person hits the upper joist upper plate, a viscoelastic material (for example, rubber or the like) is provided between the upper joist upper plate 70 and the plate member 20. ) Is preferably sandwiched.
[0025]
The outer joist support structure 80 has a viscoelastic support member 81 for supporting the upper joist upper plate 70 from below and is placed on the floor foundation. The viscoelastic support member 81 is preferably a vibration isolator disclosed in Japanese Patent Publication No. 7-35838. The lower portion of the viscoelastic support member 81 (the lower surface of the bowl-shaped extended portion of the vibration isolator) is placed on the upper surface of the floor foundation, and the upper surface (the top portion of the vibration isolator) holds the lower surface of the upper joist upper plate 70. To do.
The number of viscoelastic support members 81 is determined by the magnitude of the load acting on the joist upper plate 70. As the number of viscoelastic support members 81 increases, the spring constant of the joist support structure 80 as a whole increases, and sinking due to a load decreases.
When a vibration isolator is employed as the viscoelastic support member 81, the joist upper plate 70 corresponds to the load plate member of the vibration isolator in Japanese Patent Publication No. 7-35838.
[0026]
The wall-wall gap filling material 90 is made of a viscoelastic material, and the right and left ends of the wall plate material 10 that forms the wall 3 and the surface of the other wall plate material 10 that forms the other wall 3 that intersects the wall 3. The gaps between them are filled.
The wall floor gap filling material 91 is made of a viscoelastic material, and is filled in a gap between the lowermost part of the wall board material 10 forming the wall 3 and the upper surface of the floor board material 20 forming the floor 4.
The wall-to-ceiling gap filling material 92 is made of a viscoelastic material, and is filled in a gap between the uppermost part of the wall board material 10 that forms the wall 3 and the lower surface of the ceiling board material 30 that forms the ceiling 5.
The state of the gap filled with the wall-wall gap filler 90, the wall-floor gap filler 91, or the wall-to-ceiling gap filler 92 is the same as the gap filled with the plate gap fillers 11, 21, 31, and will be described. Omitted.
[0027]
Next, it is provided inside the foundations 6, 7, 8 that are the wall foundation 6, the floor foundation 7, or the ceiling foundation 8 of the room 2 composed of the wall 3, the floor 4, and the ceiling 5 according to the embodiment of the present invention. The function of the building interior structure 1 will be described.
The vibration of the foundation, which is the wall foundation 6, floor foundation 7, or ceiling foundation 8, propagated from the upper and lower floors and adjacent rooms, etc., is divided into solid sound and air propagation sound. I will explain.
Here, the solid sound is sound that propagates through the solids of the foundations 6, 7, 8 and the plate members 10, 20, 30 and is finally radiated from the surface of the plate member into the room 2. Air propagation sound is sound that radiates from the surfaces of the foundations 6, 7, and 8, propagates in the air, and enters the interior of the room 2.
[0028]
First, propagation of solid sound will be described.
The vibration transmitted to the foundations 6, 7, 8 such as the wall foundation 6, the floor foundation 7, or the ceiling foundation 8 is transmitted through the wall board material support structure 40, the floor board material support structure 50, or the ceiling board material support structure 60. It is going to propagate to board materials, such as board material 10, floor board material 20, or ceiling board material 30. FIG.
Propagation from the foundations 6, 7, 8 to the plate members 10, 20, 30 by appropriately adjusting the natural frequency of the vibration system composed of the plate member support structures 40, 50, 60 and the plate members 10, 20, 30. Solid sound can be suppressed. In particular, when the vibration isolator is employed for the plate material support structures 40, 50, 60, the natural frequency can be easily adjusted and the propagation of solid sound can be easily suppressed.
Since the viscoelastic support member supports the plurality of plate members 20, 30, and 40, the solid sound is effectively attenuated.
Since the viscoelastic support member supports the plurality of plate members 20, 30, and 40 and there is a gap between the plurality of plate members 20, 30, and 40, there is no propagation of solid sound between the plate members. It is possible to prevent vibration propagated to one plate material from propagating to another plate material.
Since the gap between the plurality of plate members is filled with the plate member gap filler made of viscoelastic material, the plate member gap filler absorbs and attenuates the vibration energy of the plate member.
[0029]
Next, radiation of air-borne sound will be described.
The sound (sound pressure energy) radiated from the surfaces of the foundations 6, 7, 8 due to the vibration transmitted to the foundations 6, 7, 8 of the wall foundation 6, floor foundation 7, or ceiling foundation 8 becomes 8 fills the gap between the plate members 10, 20, and 30.
Since the gap between the wall boards 10, the gap between the floor boards 20, and the gap between the ceiling boards 30 are filled with the board gap filling material made of viscoelastic material, the boundary between the board and the board where the air-propagating sound is adjacent to each other. Will not leak into the interior of the room 2.
Since the gap between the wall and the floor, the wall and the wall, and the wall and the ceiling is filled with the plate gap material made of viscoelastic material, the wall and floor where the air-borne sound is adjacent, the wall and the wall, and the wall and the ceiling It does not leak into the room 2 through the border.
Since the space between the edge of the board and the foundation is vacant, the air propagation sound radiated from the surface of the wall foundation 6 wraps around the gap between the floor foundation 7 and the floor board 20 or between the ceiling foundation 8 and the ceiling board 30. , Sound energy is dispersed and vibration is suppressed. Moreover, the air propagation sound radiated | emitted from the surface of the floor foundation 7 goes around to the clearance gap between the wall foundation 6 and the wall board material 10, a sound energy is disperse | distributed, and a vibration is suppressed. Further, the air-propagating sound energy radiated from the surface of the ceiling foundation 8 wraps around the gap between the wall foundation 6 and the wall plate material 10, and the sound energy is dispersed and vibration is suppressed.
Moreover, when the air propagation sound energy radiated | emitted from the surface of the wall foundation 6 vibrates a wall board again and becomes a solid sound, a vibration is suppressed by the vibration suppression effect between wall boards.
[0030]
If the building floating interior structure provided inside the wall foundation, floor foundation, or foundation that is the ceiling foundation of the room constituted by the wall, floor, and ceiling of the above-described embodiment, it is constituted by a plate material support structure and a plate material. The solid sound propagating from the foundation to the plate can be suppressed by appropriately adjusting the natural frequency of the vibration system.
In addition, since the vibration isolator is employed in the plate material support structure, it is possible to efficiently attenuate the vibration component related to the solid sound and easily prevent the generation of the solid sound.
Moreover, since the viscoelastic support member fixes the periphery of the plurality of plate members and attenuates the vibration, the solid sound can be effectively attenuated.
In addition, since the viscoelastic support member supports a plurality of plate materials and there are gaps between the plurality of plate materials, vibration between the plate materials is suppressed, and solid sound generated in one plate material propagates to other plate materials. Can be prevented.
Further, since the gap between the plurality of plate members is filled with the plate member gap filler made of viscoelastic material, the viscoelastic material absorbs and attenuates the vibration energy between the plate members.
Therefore, acoustic radiation from the plate material due to solid sound propagation is extremely reduced.
[0031]
Furthermore, if the building floating interior structure provided on the inside of the wall foundation of the room composed of the wall, the floor and the ceiling of the above-mentioned embodiment, the floor foundation, or the foundation which is the ceiling foundation, the gap between the wall plate materials, Since the gap between floor boards and the gap between ceiling boards are filled with viscoelastic material board gap filler, there is no generation of air propagation sound and leakage of air propagation sound, There is no leakage inside.
In addition, since the space between the end of the plate and the foundation is vacant, the air-propagating sound energy radiated from the surface of the wall foundation wraps around the gap between the floor foundation and the floor board or between the ceiling foundation and the ceiling board. Sound energy is dispersed and vibration is suppressed. Moreover, since the air propagation sound energy radiated from the surface of the floor foundation wraps around the gap between the wall foundation and the wall plate material, the sound energy is dispersed and vibration is suppressed.
Moreover, since the air propagation sound energy radiated from the surface of the ceiling foundation wraps around the gap between the wall foundation and the wall plate material, the sound energy is dispersed and vibration is suppressed.
Moreover, when the solid sound energy radiated from the surface of the wall foundation vibrates the wall plate again, the vibration is suppressed by the vibration suppressing effect between the wall plates.
Therefore, due to the air-borne sound propagation, there is very little acoustic entry into the room.
[0032]
The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
Although the example in which the structure of the present invention is applied to the wall foundation part, the floor foundation part, and the ceiling foundation part has been described, the present invention is not limited thereto.

Moreover, although demonstrated with the structure which applied the vibration isolator which the inventor invented to the viscoelastic support member, it is not limited to this, You may employ | adopt the member made from the other viscoelastic material.
In addition, it has been described that there is a plate material gap filler in the gap between the plate materials, but the plate material gap filler is not limited to the case of filling by filling work, for example, pasted strip-like plate material gap filler is pasted with an adhesive May be.
Further, although there is a gap between the plate materials, the size of the gap may have a narrow portion and a wide portion, and the plate materials may be in contact with each other within a range where the effect of the present invention is exhibited in the narrow place.
Moreover, although the foundation shown in figure looks like a slab, it is not limited to this, For example, the boundary wall added in order to divide the large room formed with the slab may be sufficient.
In addition, although it has been described that there is a gap between the lower end of the wall and the floor surface, and the gap is filled with a wall-floor spacing filler, the present invention is not limited to this, and a gap is provided between the end of the floor and the wall surface. There may be a wall-floor spacing filler in the gap.
In addition, although it has been described that there is a gap between the lower end of the wall and the ceiling surface, and the gap is filled with a wall-to-ceiling gap filler, the present invention is not limited to this, and a gap is provided between the ceiling end and the wall surface. There may be a wall-to-ceiling spacing filler in the gap.
[0033]
【The invention's effect】
As described above, the building floating interior structure provided inside the wall foundation, floor foundation, or foundation which is the ceiling foundation of the room composed of the wall, floor and ceiling according to the present invention has the following effects. Have
Since there is a plate material gap filler in the gap between the plate materials, vibrations from the foundation do not easily propagate to the plate material, and air propagation sound from the foundation does not easily enter the interior of the room from the boundary between the plate material and the plate material, and the plate material gap filler is adjacent. Since the vibration of the combined board material is attenuated, the vibration from the foundation that is the foundation, floor foundation, or ceiling foundation is suppressed from propagating to the wall, floor, or ceiling, and the generation of solid sound is suppressed, resulting in room Increases the shielding effect of the sound radiated inside.
In addition, because the joist upper plate is provided, the vibration of the wall foundation does not propagate to the floor through the joist upper plate, and the vibration of the floor foundation propagates to the floor through the joist upper plate. This is suppressed by the viscoelastic support member, so that the vibration of the wall foundation and the floor foundation can be prevented from entering the interior of the room, and the vibration hardly propagates from the foundation to the internal member of the room.
Also, since the wall and floor foundation are separated, the floor and wall foundation are separated, and there is a wall floor gap filling material in the gap between the wall and floor, when sound radiated by the vibration of the foundation vibrates the wall or floor In addition, the vibration of the plate material is attenuated by the wall and floor gap filling material to suppress the emission of solid sound, and the sound radiated from the wall foundation or floor foundation surface leaks from the boundary between the wall and floor and enters the room. It is possible to prevent the sound radiated from the surface of the wall foundation and the floor foundation from entering the room.
Also, since the wall and ceiling foundation are separated, the ceiling and wall foundation are separated, and there is a wall ceiling gap filler in the gap between the wall and ceiling, so the sound emitted by the vibration of the foundation vibrated the wall or ceiling At the same time, the wall ceiling clearance filler attenuates the vibration of the plate material and can suppress the emission of solid sound, and the sound radiated from the wall foundation or the surface of the ceiling foundation leaks from the boundary between the wall and the ceiling and indoors. It is possible to prevent the sound radiated from the surfaces of the wall foundation and the ceiling foundation from entering the interior of the room.
In addition, as described above, the wall foundation of a room composed of the wall and floor according to the present invention, or the interior structure of a floating building provided inside the foundation that is the floor foundation, causes vibration of the wall foundation. The viscoelastic support member prevents the vibration of the floor foundation from propagating to the floor via the joist upper plate, and the vibration of the wall foundation and the floor foundation is suppressed.
