Description

本発明は、ドラムや金管楽器などの大音量や振動を伴う楽器の演奏を可能とする集合住宅の防音構造に関するものである。   The present invention relates to a soundproof structure for an apartment house that enables performance of musical instruments with high volume and vibration such as drums and brass instruments.

従来から、集合住宅において楽器演奏を可能とした二重構造の防音マンションが存在している。二重構造の防音マンションの防音性能は遮音等級Dr−60〜Dr−70程度であり、ピアノやギター、木管楽器の演奏(100dB以下の演奏音)は可能であった。   Conventionally, there are soundproof apartments with a double structure that allow musical instruments to be played in apartment houses. The soundproofing performance of the soundproofing apartment with a double structure is about sound insulation grade Dr-60 to Dr-70, and the performance of piano, guitar and woodwind instruments (performance sound of 100 dB or less) was possible.

例えば、特許文献1に記載された防音室構造は、床スラブの上面に防音機能を有する筒状の外側壁を構築し、外側壁の内側に位置するように、床スラブの上面にクッション材を介して遮音ボックスを構築し、外側壁と遮音ボックスとの間に吸振手段を介在させている。この構成によって、遮音ボックスのレイアウトの自由度が向上するようになる。   For example, in the soundproof room structure described in Patent Document 1, a cylindrical outer wall having a soundproof function is constructed on the upper surface of the floor slab, and a cushioning material is provided on the upper surface of the floor slab so as to be positioned inside the outer wall. A sound insulation box is constructed, and a vibration absorbing means is interposed between the outer wall and the sound insulation box. With this configuration, the freedom of layout of the sound insulation box is improved.

(効果)
次に、本実施例の集合住宅の防音構造1の奏する効果を列挙して説明する。
(effect)
Next, the effect which the soundproof structure 1 of the apartment house of a present Example show | plays is enumerated and demonstrated.

(1)上述してきたように、本実施例の集合住宅の防音構造1は、集合住宅の防音構造Sであって;それぞれコンクリート躯体である、第1の床11と、第1の壁12と、第1の天井13と、から構成される第1の構造10と;第1の構造10内に構築される第2の構造20であって、第1の床11上に構築される防振構造の第2の床21と、第1の壁12内に構築される防振構造の第2の壁22と、第1の天井13下に構築される防振構造の第2の天井23と、から構成される第2の構造20と;第2の構造20内に構築される第3の構造30であって、第2の床21上に構築される防振構造の第3の床31と、第2の壁22内に第2の壁22から完全に切り離して構築される第3の壁32と、第2の天井23下に第2の天井23から完全に切り離して構築される第3の天井33と、から構成される第3の構造30と;を備える。このような構成によれば、ドラムや金管楽器などの大音量や振動を伴う楽器の演奏を可能とする集合住宅の防音構造Sとなる。 (1) As described above, the soundproof structure 1 of the apartment house of the present embodiment is the soundproof structure S of the apartment house; the first floor 11 and the first wall 12 each of which is a concrete frame. A first structure 10 composed of a first ceiling 13; a second structure 20 constructed in the first structure 10 and constructed on the first floor 11; A second floor 21 having a structure, a second wall 22 having a vibration-proof structure built in the first wall 12, and a second ceiling 23 having a vibration-proof structure built under the first ceiling 13. A third structure 30 constructed in the second structure 20, and a third floor 31 having an anti-vibration structure constructed on the second floor 21. A third wall 32 constructed completely separated from the second wall 22 in the second wall 22, and completely from the second ceiling 23 under the second ceiling 23. A third ceiling 33 constructed separately, and the third structure 30 consists of; comprises. According to such a configuration, the soundproof structure S of an apartment house that enables performance of musical instruments with high volume and vibration such as drums and brass instruments is provided.

具体的にいうと、従来の構造では遮音等級Dr−70を越える遮音性能の確保が困難であり、隣室のドラムや金管楽器の演奏音をほとんど聞こえないレベルまで減衰することはできなかった。コンクリート躯体を厚くすれば、理論上は遮音性能を確保することはできるものの、その場合には壁厚が1800mm必要となり、現実的ではなかった。これに対して、本実施例の集合住宅の防音構造1によれば、集合住宅の隣戸間界壁・隣戸間界床における空間音圧レベル差で遮音等級Dr−90程度の設計性能を得ることができる。   Specifically, in the conventional structure, it is difficult to ensure sound insulation performance exceeding the sound insulation grade Dr-70, and the performance sound of the drums and brass instruments in the adjacent room could not be attenuated to a level where it can hardly be heard. If the concrete frame is thickened, the sound insulation performance can be secured theoretically, but in that case, the wall thickness is required to be 1800 mm, which is not practical. On the other hand, according to the soundproof structure 1 of the apartment house of the present embodiment, the design performance of the sound insulation grade Dr-90 is obtained by the difference in the spatial sound pressure level at the boundary wall between the adjacent doors and the boundary floor between the adjacent doors of the apartment house. Can do.

さらにいうと、第3の構造を従来型の吊天井方式で実施しようとしても、第2の構造自体が防振吊具を介して躯体コンクリート天井から吊っている。そのため、第3の構造を第2の構造に吊ることとなり、構築精度が低くなるため、結果として気密性が確保できずに高い遮音性が確保できなくなっていたのである。   Furthermore, even if it is going to implement the 3rd structure by the conventional suspension ceiling system, the 2nd structure itself is suspended from the frame concrete ceiling via the vibration proof suspension. For this reason, the third structure is suspended from the second structure, and the construction accuracy is lowered. As a result, airtightness cannot be ensured and high sound insulation cannot be secured.

(2)第2の床21は第1の床11上に吸音部材21aを介して打設される浮床コンクリートであり、第3の床31は第2の床21上に吸音部材31aを介して打設される浮床コンクリートであることが好ましい。このような構成によれば、簡易な構成によって第2の床21及び第3の床31を防振構造とすることができる。さらに、第3の床31には、フレーム構造体40が載置されるところ、第3の床31がスラブとして形成されていることで、フレーム構造体40を安定して支持できるうえ、全体の剛性を大きくすることができる。 (2) The second floor 21 is floating floor concrete placed on the first floor 11 via a sound absorbing member 21a, and the third floor 31 is placed on the second floor 21 via a sound absorbing member 31a. The float floor concrete is preferably cast. According to such a configuration, the second floor 21 and the third floor 31 can have a vibration-proof structure with a simple configuration. Furthermore, when the frame structure 40 is placed on the third floor 31, the third floor 31 is formed as a slab, so that the frame structure 40 can be stably supported and the entire structure can be supported. The rigidity can be increased.

(3)第3の構造30は、第2の床21上に吸音部材31aを介して打設される浮床コンクリートである第3の床31と、浮床コンクリート上に設置されるフレーム構造体40に取り付けられる第3の壁32及び第3の天井33と、から構成されることが好ましい。このような構成によれば、第3の構造30の第3の壁32及び第3の天井33を、簡単な構成によって第2の構造20から切り離すことができる。そして、従来のように、コンクリート躯体だけで遮音性能を達成するためには1800mm必要であった壁厚を、隣戸間界壁を660mmまで薄くでき、隣戸間界床を760mmまで薄くできる。 (3) The third structure 30 includes a third floor 31 that is a floating floor concrete placed on the second floor 21 via a sound absorbing member 31a, and a frame structure 40 that is installed on the floating floor concrete. The third wall 32 and the third ceiling 33 to be attached are preferably configured. According to such a configuration, the third wall 32 and the third ceiling 33 of the third structure 30 can be separated from the second structure 20 with a simple configuration. As in the prior art, the wall thickness required to achieve sound insulation performance with only the concrete frame can be reduced to 1660 mm, the boundary wall between adjacent doors can be reduced to 660 mm, and the boundary floor between adjacent doors can be reduced to 760 mm.

さらに、第3の構造30は、第2の構造20(及び第1の構造10)の内側に配置されるため、フレーム構造体40の各部材41、42、43の長さを短くすることができる。これによって部材断面を小さくすることができる。したがって、室内空間を広くとることができる。すなわち、第2の構造20は従来型の吊天井などを用いるとともに、第3の構造30にはフレーム構造体40を用いることで合理的な空間設計が可能となる。逆に言うと、第2の構造20までもフレーム構造体を用いようとすると、部材断面が大きくなってしまうため、合理的とはいえないのである。   Furthermore, since the third structure 30 is disposed inside the second structure 20 (and the first structure 10), the length of each member 41, 42, 43 of the frame structure 40 can be shortened. it can. As a result, the member cross section can be reduced. Therefore, a large indoor space can be taken. In other words, the second structure 20 uses a conventional suspended ceiling or the like, and the third structure 30 uses the frame structure 40 to enable rational space design. In other words, if the frame structure is to be used up to the second structure 20, the member cross section becomes large, which is not reasonable.

(4)また、集合住宅の防音構造Sは、第1の構造10に設置される二重構造51の窓と、第3の構造30に設置される気密構造の窓53と、二重構造の窓51と気密構造の窓53の間に構築される中空層52と、から構成される三重窓構造50をさらに備えることが好ましい。このような構成によれば、窓を通じて隣室へ音が漏れることを防止できる。具体的には、二重構造の窓51(T−4)と気密構造の窓53(T−3)で75dB以上の設計性能が得られるため、隣室に回り込む空間音圧レベル差は75+75=150dB以上となる。 (4) In addition, the soundproof structure S of the apartment house includes a double structure 51 window installed in the first structure 10, an airtight structure window 53 installed in the third structure 30, and a double structure. It is preferable to further include a triple window structure 50 including a hollow layer 52 constructed between the window 51 and the window 53 having an airtight structure. According to such a configuration, it is possible to prevent sound from leaking to the adjacent room through the window. Specifically, a design performance of 75 dB or more is obtained by the double-structured window 51 (T-4) and the hermetic-structured window 53 (T-3). Therefore, the difference in the spatial sound pressure level entering the adjacent room is 75 + 75 = 150 dB. That's it.

(5)そして、本実施例の集合住宅は、すべての住戸が、上述したいずれかの集合住宅の防音構造Sを備える。このような構成によれば、各住戸での防音性能が隣室の防音性能との相乗効果によって倍増される。 (5) And in the apartment house of the present embodiment, all the dwelling units are provided with the above-described soundproof structure S of the apartment house. According to such a configuration, the soundproof performance in each dwelling unit is doubled by a synergistic effect with the soundproof performance of the adjacent room.

以上、図面を参照して、本発明の実施例を詳述してきたが、具体的な構成は、この実施例に限らず、本発明の要旨を逸脱しない程度の設計的変更は、本発明に含まれる。   The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to the present invention. included.

例えば、実施例では、フレーム構造体40を構成する各部材に角パイプを用いる場合について説明したが、これに限定されるものではない。各部材には、例えばC形鋼などの他の形鋼を用いることもできる。   For example, in the embodiment, the case where a square pipe is used for each member constituting the frame structure 40 has been described, but the present invention is not limited to this. Other members such as C-shaped steel can be used for each member.
