この発明は、コンクリートスラブ等の床基盤上に吸音性
を有する弾性体を直接敷設した防音床構造に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a soundproof floor structure in which a sound-absorbing elastic body is directly laid on a floor base such as a concrete slab.
コンクリートスラブ等の床基盤に仕上材を直接貼付けた
Ｗｉ造の床構造が各種開発されている。この床構造にあ

をもたらす等、住宅環境の悪化が大きな問題となってい
る。Various Wi-frame floor structures have been developed in which finishing materials are directly attached to a floor base such as a concrete slab. In this floor structure, if a relatively hard material such as wood or synthetic resin is used as the finishing material, it will reduce noise from daily life, especially when something is dropped on the floor in an apartment building such as an apartment building. The generated impact sound propagates downstairs as solid sound, causing loud noise and deteriorating the residential environment, which has become a major problem.
そこで、その衝撃音を効果的に吸収する防音手段として
各種弾性体が開発され使用されている。Therefore, various elastic bodies have been developed and used as soundproofing means to effectively absorb the impact noise.
ところが、このような弾性体を床基盤上に敷設すると、
例えば仕上材として比較的硬質の木質系のものを使用し
ても、床に立ったときに体重をかけた部分が若干撓んだ

した場合には、床下に溜る湿気により、グラスウール等
が加水分解をおこす等して緩衝性が低下するとともに、
クリープ等をおこし床の沈み等が発生する虞れがある。However, when such an elastic body is laid on the floor base,
For example, even if a relatively hard wood-based material is used as a finishing material, the softness of the floor may cause the floor to bend or sink slightly when you put your weight on it when you stand on it. This results in a loss of the original hardness of the system. Moreover, when a porous fiberboard such as glass wool is used as the elastic body, moisture accumulating under the floor causes hydrolysis of the glass wool, reducing its cushioning properties.
There is a risk that creep may occur and the floor may sink.
また、このような防音手段の１つとして、乾式浮床工法
が知られている。この乾式浮床工法は、高防音性能とと
もに木質系本来の硬さを生かすことができ、その点では
好都合なものであるが、構造上床の高さに一定の制約が
あり（例えば６０ｍ。Furthermore, a dry floating floor construction method is known as one of such soundproofing means. This dry floating floor construction method is advantageous in that it can take advantage of the inherent hardness of wood as well as its high soundproofing performance, but due to its structure, there are certain restrictions on the height of the floor (for example, 60 m).
以下は不可）、マンション等の高層住宅には不向きであ
る。(The following are not allowed) and are not suitable for high-rise residential buildings such as condominiums.
そこで、この発明は、上記した従来の事情に鑑み、床面
に対し一定の硬さ、例えば木質法本来の硬さを確保する
ことができるとともに、防音性に優れ、しかも床の高さ
に一定の制限がない防音床構造を提供することを目的と
するものである。Therefore, in view of the above-mentioned conventional circumstances, this invention can ensure a certain hardness for the floor surface, for example, the original hardness of the wood method, has excellent soundproofing properties, and has a constant hardness at the floor height. The purpose of this project is to provide a soundproof floor structure that does not have such limitations.
また、この発明は、湿気等に起因する衝撃性の低下を防
止するとともにクリープ等をおこして床に沈みが発生す
るのを防止することができる防音床構造を提供すること
を目的とするものである。Another object of the present invention is to provide a soundproof floor structure that can prevent the impact resistance from decreasing due to moisture, etc., and prevent the floor from sinking due to creep, etc. be.

合せた防音床構造において、前記弾性体と仕上材との間

を有する質量体を配設したものである。That is, the invention according to claim 1 provides a soundproof floor structure in which a sound-absorbing elastic body is disposed on a floor base and a finishing material is laminated on the elastic body. A mass body having a higher specific gravity than the elastic body and having vibration damping properties is disposed between them.
また、この発明に係る請求項２の防音床構造は、質量体
が、少なくとも比重１．５以上であって、かつ、重量１
０ｋｇ／ｍ’以上であることを特徴とするものである。Further, in the soundproof floor structure according to claim 2 of the present invention, the mass body has a specific gravity of at least 1.5 or more, and has a weight of 1.
It is characterized by being 0 kg/m' or more.
また、この発明に係る請求項３の防音床構造は、弾性体
の内部又は質量体の内部若しくは前記弾性体と質量体と
の間に、その弾性体内部から吐出される空気を床上方下
方、側面に逃がす通気手段を設けたものである。Further, in the soundproof floor structure according to claim 3 of the present invention, air discharged from inside the elastic body is directed upward and downward from the floor, inside the elastic body, inside the mass body, or between the elastic body and the mass body. It is equipped with ventilation means on the side.
この発明の請求項１に係る防音床構造は、吸音効果が大
きいが、その反面床面歩行時に床の撓みをもたらす虞れ
がある弾性体に対し、その上部に質量体を配設すること
により、床面に対して一定の硬さを確保しつつ、同時に
高防音性能を発揮することができ、しかも乾式浮床工法
のような床基盤からの最低高に大きな制約が課せられる
ことがない。The soundproof floor structure according to claim 1 of the present invention has a large sound absorbing effect, but on the other hand, it is possible to prevent the elastic body from causing the floor to bend when walking on the floor by disposing a mass body on top of the elastic body. , it is possible to ensure a certain level of hardness for the floor surface while at the same time exhibiting high soundproofing performance, and there is no large restriction on the minimum height from the floor base as in the dry floating floor construction method.

その通気手段によって床下側と弾性体との間に空気の流
通が図られたものにあっては、床下内に閉じ込められた
空気がもたらす、所謂空気バネの作用により緩衝性が低
下する現象も同時に防止できる。In addition, the soundproof floor structure according to claim 3 of the present invention is capable of allowing the air inside the elastic body to escape to the upper side, side surface, or underside of the floor by the ventilation means. This allows the moisture to escape to the upper side, side surface, or lower side of the floor, thereby preventing deterioration of the elastic body and sinking of the floor due to moisture. Moreover,
If the ventilation means allows air to circulate between the underfloor and the elastic body, there is also a phenomenon in which the cushioning properties are reduced due to the action of the so-called air spring caused by the air trapped in the underfloor. It can be prevented.
