Description

【０００１】
【発明の属する技術分野】
本発明は、建物の壁支持構造と壁構造に係る。特に壁基礎と壁板材の間に介在する支持構造に特徴の有る建物の壁支持構造と壁構造に関する。
【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、基礎や壁材に入射した振動をいかに減衰させ、他の基礎や壁材に伝えないかがポイントとなる。
【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、その構造により床壁や天井壁での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、部屋の内部で発生した音が、壁、床、天井の壁材、床材、天井材を振動させ、その振動が床基礎、壁基礎、天井基礎に伝わり、上記の経路を通って他の部屋に伝わる。
例えば、壁では、壁基礎に固定された支持構造体が壁板材を支持している。壁基礎が振動すると、その振動エネルギーが支持構造体を介して壁板材に伝搬する。壁板材が振動し、部屋の内部に固体音を放射する。また、部屋の内部で発生した音は、壁板材を振動させ、その振動エネルギーが支持構造体を介して、壁基礎に伝わり、上述の経路を伝わって、他の部屋の内部に固体音を放射する。
従って、壁から部屋に放射される固体音のレベルを下げるためには、壁基礎と壁板材との間で振動を伝えにくい壁支持構造と壁構造とが望まれていた。
【０００６】
一方、発明者は、前述の防振装置の構造が従来の壁に使用されている支持構造体に比較して優れた振動減衰特性を有していることを見いだした。
【０００７】
本発明は以上に述べた問題点に鑑み、上記の知見を基に、案出されたもので、従来の建物の壁基礎をベースとして壁板材を支持する壁支持構造にかわって、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ることができ、また施工の容易な建物の壁支持構造と壁構造とを提供しようとする。
【０００８】
【課題を解決するための手段】
上記目的を達成するため、本発明にかかる建物の壁基礎をベースとして壁板材を支持する壁支持構造は、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てなる支持部材と、前記鍔状展出部が収まる穴を設けられた板状部と前記鍔状展出部を前記対象物に押し付ける様に該穴の周囲に設けられた押し付け部とを有する支持部材保持具と、を備え、前記支持部材保持具が前記対象物に相当する壁基礎または壁板材のうちの一方に固定され、前記支持部材保持具が前記鍔状展出部を前記対象物に相当する壁基礎または壁板材のうちの一方に押し付け、壁基礎または壁板材のうちの他方が前記頂部に固定されるものとした。

【発明の実施の形態】

【００２５】
図１は、本発明の実施形態の全体側面図である。図２は、本発明の第一の実施形態の側面断面図である。図３は、本発明の第一の実施形態のＢ−Ｂ断面図である。
【００２６】
建物１は、壁基礎６と床基礎７と天井基礎８とで構成される。部屋２が、壁基礎６と床基礎７と天井基礎８とで区切られた空間の中に形成される。部屋２は、壁３と床４と天井５とで囲まれた空間である。壁支持構造９が、壁基礎６をベースとして壁板材５０を支持する。同じく、床支持構造が、床基礎７をベースとして床板材を支持し、天井支持構造が天井基礎をベースとして天井板材を支持する。

【００２８】
壁板材５０は、壁面を形成する板材であり、例えば、石膏ボード、壁用ベニア板等の建材である。
【００２９】
支持部材１０は、後述する支持部材保持具２０により壁基礎６に押し付けられ壁板材５０を支持するためのものであり、ほぼ椀状をなす本体１１を粘弾性材料で形成し、本体開口側端縁に鍔状展出部１３を設け、鍔状展出部１３の対象物に対向する面に環状の突起１４を設け該対象物に接触し本体内部をほぼ気密構造とし、本体の肉厚を前記鍔状展出部から頂部１２に向け減少させてなる部材である。
【００３０】
支持部材保持具２０は、壁基礎６に固定され支持部材１０を壁基礎６に押し付けるためのものであり、板状部２１と押し付け部２２とを有する。
板状部２１は、壁基礎６に固定可能になっており鍔状展出部１３が収まる穴Ｈを設けられた板状の部分である。
押し付け部２２は、鍔状展出部１３を前記対象物に相当する壁基礎６に押し付ける様に該穴Ｈの周囲に設けられる部分である。
【００３１】
各種の形式の支持部材保持具２０を、図を基に、詳述する。図６は、支持部材保持具２０の第１の実施例である。図７は、支持部材保持具２０の第２の実施例である。図８は、支持部材保持具２０の第３の実施例である。

ところで、図６〜図８に示した支持部材保持具２０はさらに鍔状部２３を持っているが、これは後述する第二の実施形態に係る壁支持構造にも兼用するためであり、第一の実施形態に係る支持部材保持具２０ではなくてもよい。
【００３２】
壁支持具３０は、支持部材１０に固定され壁板材５０を支持するための部材であり、裏側を支持部材１０の頂部１２に固定可能であり表側に取付面３１を持つ長手部材である。
図３には、四辺形に折り曲げられ一辺の中央部が切り欠かれた断面を持った薄板の長手部材が示されている。この部材を「Ｍバー」と呼称する。「Ｍバー」の切り欠き部に対向する辺の外側の面が取付面３１を形成する。支持部材１０の頂部１２を固定するネジ穴と壁板材５０を固定するネジ穴とが「Ｍバー」の切り欠き部に対向する辺に設けられる。

第一の実施形態の壁支持構造と壁構造の施工方法を説明する。
支持部材保持具２０が、板状部２１を壁基礎６に当接する様に配置され、取付ネジ２５又は接着剤で壁基礎６固定される。支持部材保持具２０は、所定の間隔で壁基礎６の表面に均等に配置される。特に、接着剤で固定した場合、壁基礎に塗った接着剤が、取付穴から溢れて取付穴の上部で玉状に固化して、支持部材保持具２０が剥がれるのを防止する。
支持部材１０の鍔状展出部１３が、支持部材保持具２０の穴Ｈに収められる。支持部材保持具２０の押し付け部２２が支持部材１０の鍔状展出部１３を壁基礎６へ押し付けて、環状の突起１４が壁基礎６に接触する。
壁支持具３０が、支持部材１０の頂部１２に固定ネジ３２で固定される。壁支持具３０の長さは、部屋２の天井高さまたは壁幅より僅かに短い。通常は、壁支持具３０は、長手方向が垂直または水平になるように配置される。

【００３５】
次に、本発明の第一の実施形態に係る壁支持構造と壁構造の防音上の作用を説明する。
建物で発生した振動・騒音は、固体音となって基礎に伝搬する。
壁基礎に伝わった振動エネルギーは、支持部材１０に伝搬する。支持部材１０は、その振動減衰特性により振動加速度を減衰し、振動エネルギーを小さくする。小さくなった振動エネルギーは、頂部１２から壁支持具３０へ伝搬する。壁支持具３０の振動エネルギーは、粘弾性部材４０を介して壁板材５０へ伝搬する際に、さらに振動加速度を減少させ、壁板材５０へ伝搬する。壁板材５０が振動すると、部屋２の内部の空気を加速して、部屋２へ音響を放射する。
支持部材１０は、加振力で振動される鍔状展出部または頂部のうちの一方の加速度に比較し、鍔状展出部または頂部のうちの他方の加速度が小さいという振動減衰特性を持っているので、部屋２の内部へ放射される音響エネルギーが小さくなる。
【００３６】
次に、本発明の第二の実施形態に係る壁支持構造と壁構造とを説明する。
図１は、本発明の実施形態の全体側面図である。図４は、本発明の第二の実施形態の側面断面図である。図５は、本発明の第二の実施形態のＢ’−Ｂ’断面図である。

鍔状部２３は、板状部２１の縁に設けられ後述するレール状固定具６０の溝Ｇに長手方向に摺動自在に嵌合する部分である。
【００３９】
鍔状部２３の構造を、図６乃至図８を基に説明する。

図５には、所定の幅を持った板材でできた平板部６１と、平板部６１の両側６２が折り曲げられて形成された所定の深さと所定の幅の溝Ｇとを持った長手部材が示されている。
さらに、取り付け用穴がレール状固定具６０の平板部６１に設けられている。
溝Ｇの所定の深さと所定の幅の寸法は、支持部材保持具２０の鍔状部２３が嵌合し長手方向へ摺動するのに適当な値である。

次に、本発明の第二の実施形態に係る壁支持構造と壁構造の防音上の作用を説明する。
建物で発生した振動・騒音は、固体音となって基礎に伝搬する。
壁基礎に伝わった振動エネルギーは、レール状固定具６０に伝搬する。レール状固定具６０に伝わった振動エネルギーは、支持部材１０に伝搬する。支持部材１０は、その振動減衰特性により振動加速度を減衰し、振動エネルギーを小さくする。小さくなった振動エネルギーは、頂部１２から壁支持具３０へ伝搬する。壁支持具３０の振動エネルギーは、粘弾性部材４０を介して壁板材５０へ伝搬する際に、さらに振動加速度を減少させ、壁板材５０へ伝搬する。壁板材５０が振動すると、部屋２の内部の空気を加速して、部屋２へ音響を放射する。
支持部材１０は、加振力で振動される鍔状展出部または頂部のうちの一方の加速度に比較し、鍔状展出部または頂部のうちの他方の加速度が小さいという振動減衰特性を持っているので、部屋２の内部へ放射される音響エネルギーが小さくなる。
【００４３】
【実施例】
以下で、第一又は第二の実施形態にかかる壁支持構造が壁基礎の振動を室内に漏れるのを抑制する性能を、モデル試験結果により説明する。
図９は、モデル試験結果のグラフである。
モデルは、十分に剛な上板と下板とを上下に配置し、その上板と下板との間に支持部材１０を挟んだものである。
上板をランダム加振させ、その際の上板の加速度と下板の加速度とを測定し、両方の加速度を振動数成分に分解しその比の対数（振動加速度レベル差と呼ぶ。）を評価した。
比較のために、支持部材１０のかわりにネオプレーン製の中実の球形ゴムまたは建物壁の防振用として市販されているネオプレーン製の円柱型ゴムを用いた試験も行なった。
図９では、試験結果が横軸を振動数（Ｈｚ）、縦軸を振動加速度レベル差（ｄＢ）としたグラフで示されている。振動加速度レベル差の値が大きいほど、上板の加速度に対して下板の加速度が小さく、防振性能が優れていることを示す。図９において、凡例でＣＩＶＲ−５０と記されているのが、本発明に係る支持部材である。
試験結果から、本発明の壁支持構造は、円柱型の市販ゴムまたは球形ゴムを使用した場合に比べ、ほぼ全ての振動数領域で、振動加速度レベル差が大きくなった。
このことから、本発明にかかる壁支持構造は、優れた防振効果を発揮することが分かる。

BACKGROUND OF THE INVENTION
The present invention relates to a wall support structure and a wall structure of a building. In particular, the present invention relates to a wall support structure and a wall structure of a building characterized by a support structure interposed between a wall foundation and a wall plate material.
[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, when building a wall, the point is how to attenuate the vibrations incident on the foundation and wall material and not transmit them to other foundations and wall materials.
[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.
3. A gap is provided between the foundation and the wall.
4. Devise the structure of the body edge provided between the foundation and the wall.
Etc. were devised.
[0004]
By the way, the inventor in Japanese Patent Publication No. 7-35838, “A substantially bowl-shaped main body is formed of a viscoelastic material, and a hook-shaped projecting portion is provided at an end edge of the main body opening side. An annular protrusion is provided on the surface facing the object to make contact with the object to make the inside of the main body almost airtight, and the thickness of the main body is reduced from the bowl-shaped projecting portion to the top, An anti-vibration device is disclosed in which a load plate member whose contact area changes is in contact with the top of the main body.
The anti-vibration device exhibits excellent anti-vibration performance against vibration related to solid sound on the floor wall and ceiling wall due to its structure.

[Problems to be solved by the invention]
In the case of the interior structure of a building, vibration is transmitted from the foundation such as the floor foundation, wall foundation, and ceiling foundation to the wall, floor, and ceiling, and the wall, floor, ceiling wall material, flooring, and ceiling material vibrate. Solid sound radiates from the floor and ceiling. In addition, the sound generated inside the room vibrates the walls, floors, ceiling walls, flooring, and ceilings, and the vibrations are transmitted to the floor foundation, wall foundation, ceiling foundation, and others through the above path. It is conveyed to the room.
For example, on the wall, a support structure fixed to the wall foundation supports the wall plate material. When the wall foundation vibrates, the vibration energy propagates to the wall plate material via the support structure. The wall board material vibrates and emits solid sound inside the room. In addition, the sound generated inside the room vibrates the wall plate material, and the vibration energy is transmitted to the wall foundation via the support structure, and the solid sound is radiated to the inside of the other room through the above path. To do.
Therefore, in order to lower the level of solid sound radiated from the wall to the room, a wall support structure and a wall structure that hardly transmit vibration between the wall foundation and the wall plate material have been desired.
[0006]
On the other hand, the inventor has found that the structure of the above-described vibration isolator has excellent vibration damping characteristics as compared with the support structure used for the conventional wall.
[0007]
In view of the above-described problems, the present invention has been devised based on the above-described knowledge. Instead of a wall support structure that supports a wall plate material based on the wall foundation of a conventional building, the present invention has been proposed. Therefore, it is intended to provide a wall support structure and a wall structure of a building that can improve the sound insulation performance of the room or the sound insulation performance between the rooms on the upper and lower floors, and can be easily constructed.
