【発明の詳細な説明】
（産業上の利用分野）
本発明は、ビル等のコンクリート造りの屋内等
の一居住空間を完全に仕切るための遮音壁構造に
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sound insulating wall structure for completely partitioning a living space such as an indoor space made of concrete in a building or the like.
（従来技術とその問題点）
従来、前記遮音壁としては、コンクリートの一
重壁と、コンクリートからなる中空二重壁が広く
使用されている。(Prior Art and its Problems) Conventionally, single concrete walls and hollow double walls made of concrete have been widely used as the sound insulation walls.
ところで、前者の一重壁においては、その音の
透過損失はその面密度、すなわち、壁の重量で決
まるため、重量を増加することによつてその遮音
性能を改善することができる。 By the way, in the former single wall, the sound transmission loss is determined by its areal density, that is, the weight of the wall, so the sound insulation performance can be improved by increasing the weight.
しかしながら、壁の質量を２倍にしても透過損
失は５〜5dBしか大きくならないため、高度の遮
音性を得るには壁の厚さを大とせざるを得ず、室
面積が小さくなるばかりか重量が増すため高層建
築には適用しにくい。 However, even if the mass of the wall is doubled, the transmission loss will only increase by 5 to 5 dB, so in order to obtain a high degree of sound insulation, the thickness of the wall must be increased, which not only reduces the room area but also increases the weight. increases, making it difficult to apply to high-rise buildings.
一方、後者の中空二重壁においては、その中間
に空気層が介在するため、各壁が完全に独立して
いれば、質量に見合つた値以上の透過損失を得る
ことができる。 On the other hand, in the latter hollow double wall, since there is an air layer in between, if each wall is completely independent, it is possible to obtain a transmission loss greater than a value commensurate with the mass.
しかしながら、実際には、両壁は空気層によつ
て音響的に結合され、さらに、共通の間柱等によ
つて構造的にも結合されている。 However, in reality, both walls are acoustically coupled by an air space, and furthermore, they are structurally coupled by common studs and the like.
したがつて、低周波領域（125Hz以下の周波数
領域）では、空気層がバネ作用を行ない共鳴透過
が生じ、また、高周波領域においては、壁の曲げ
波の波長と入射波の波長が一致して生じるコイン
シデンス効果により遮音低下が生じ、十分な遮音
性能が得られないという問題を有する。 Therefore, in the low frequency range (frequency range below 125 Hz), the air layer acts as a spring and resonance transmission occurs, and in the high frequency range, the wavelength of the wall bending wave matches the wavelength of the incident wave. There is a problem in that the sound insulation is degraded due to the coincidence effect that occurs, and sufficient sound insulation performance cannot be obtained.
本発明は、前記後者の中空二重壁における問題
を解決するべく、種々検討の結果前記コインシデ
ンス効果fcが、曲げ剛性を大にすれば、低音域に
移動させることができることに着目して、軽量
で、かつ、高遮音性能を有する遮音壁構造を提供
することを目的とする。 In order to solve the latter problem with the hollow double wall, the present invention focuses on the fact that the coincidence effect fc can be moved to the low frequency range by increasing the bending rigidity, and as a result of various studies. The purpose of the present invention is to provide a sound insulating wall structure having high sound insulating performance.

る。(Means for Solving the Problems) In order to achieve the above object, the present invention fills a sound absorbing material such as glass wool between the lightweight steel studs erected at appropriate intervals, and A mica-containing concrete panel having a specific gravity of 1.0 to 1.5 and a thickness of 40 to 50 mm is integrally provided on both sides with elastic supports attached to the stud surface, and has a thickness of 3 to 10 mm, and , and a rigid plate-like body having a bending elastic modulus of 300×10 3 Kg/cm 2 or more.
（実施例）
つぎに、本発明を実施例である図面にしたがつ
て説明する。(Example) Next, the present invention will be explained with reference to drawings which are examples.

ル８および弾性支持板９とからなる。 The sound insulation wall 4 is roughly made of studs 5 made of lightweight steel,
It consists of a sound absorbing material 6 such as glass wool or rock wool, a lightweight concrete panel 8 to which a fired rigid plate 7 is attached, and an elastic support plate 9.
前記焼成剛性板状体７は、厚みを大にすること

ある。そして、その厚さは、余り薄いと破損しや
すく、また、厚過ぎると質量が大となつて取扱い
が面倒である点を考慮して、３〜10mmが好まし
い。 The fired rigid plate-like body 7 has a bending elastic modulus because it is necessary to increase the bending rigidity without increasing the thickness.
300×10 3 Kg/cm 2 or more is required, and for such an object, a fired plate is the best available at present, and specifically, a large-sized ceramic plate. . The thickness is preferably 3 to 10 mm, considering that if it is too thin, it will be easily damaged, and if it is too thick, it will have a large mass and be difficult to handle.

め、これに対応するうえで40〜50mmが好ましい。 The lightweight concrete panel 8 is made by reducing the weight of conventional concrete (specific gravity 2.3) and mixing mica as an aggregate to absorb vibrations.
Since sound can easily pass through, the specific gravity is preferably 1.0 to 1.5 in order to reduce the weight of the wall as well as sound insulation, and the wall thickness is generally 150 mm, so in order to accommodate this, 40-50mm is preferred.

けたものである。 Then, a panel body A consisting of a lightweight concrete panel 8 on which the fired rigid plate-like body 7 is integrated on the surface with an adhesive or the like is attached to the stud 5 through an elastic support 9 with the fired rigid plate-like body 7 on the outside. It is attached to both sides of the

い。 Note that the method of constructing the sound insulating wall 4 is not limited to the above-mentioned method.The panel body A is attached to one side of the studs 5 via the elastic support 9, and then, between the studs 5,
The sound absorbing material 6 such as glass wool may be filled, and the panel body A may be attached to the other side of the stud 5 as described above.

示す結果を得た。 Using the sound insulation wall according to the present invention and a sound insulation wall (Comparative Example 1) in which lightweight concrete panels are attached to both sides of lightweight steel studs using metal elastic clips and glass wool is filled between the studs, the sound insulation performance can be improved. An experiment was conducted according to JIS A 1416 ``Method for measuring sound transmission loss in a laboratory'', and the results shown in Figure 3 were obtained.

A lightweight concrete panel with a specific gravity of 1.3 and a thickness of 45 mm.
As a fired rigid plate, specific gravity is 1.9 and bending elastic modulus is 370×
10 3 Kg/cm 2 , 3 mm thick large-sized ceramic plate integrated with adhesive, and a panel body is attached.
Glass wool was filled between the studs, and caulking agent was filled into the gaps between the panel bodies and between the panel bodies and the slab.

体で吸収されるためと考えられる。 As is clear from Figure 3, in Comparative Example 1, the sound insulation performance evaluation curve of the Architectural Institute of Japan was D-45.
(Noise insulation class 2). This is thought to be because the vibration of the mica-containing concrete panel in the low frequency range is absorbed by the elastic body.
一方、比較例１のものでは、高周波域において

性能の低下がみられる。 On the other hand, in Comparative Example 1, there is a significant decline in sound insulation performance in the high frequency range, which is believed to be due to a coincidence phenomenon.

インシデンス現象による遮音性能の低下がなく、
Ｄ−55（遮音等級特級）と、極めて良好な性能を
得ることができた。 However, in the sound insulation wall according to the present invention, a baked rigid plate-like body with a high bending elastic modulus is integrated into the mica-containing concrete panel, thereby increasing the bending elastic modulus of the entire wall and slightly increasing the weight of the wall. Since the vibration of the wall body in the high frequency range can be inhibited to the extent that the vibration occurs, there is no deterioration in sound insulation performance due to the coincidence phenomenon in Comparative Example 1.
We were able to obtain an extremely good performance rating of D-55 (special sound insulation grade).

である。 By the way, it is a single concrete wall with a thickness of 150mm.
The areal density is about 350Kg/ m2 and D45~50, but the sound insulation wall according to the present invention has a thickness of about 150Kg/m2 with the above-mentioned configuration.
mm, areal density of about 150Kg/ m2 , D-55, about 1/2
Despite its weight, it has good sound insulation performance.

実用に供してもよいものである。(Effects of the Invention) As is clear from the above description, according to the present invention, the panel body constituting the double wall body is a mica-containing concrete panel integrated with a fired rigid plate-like body. The panel body is mainly made of mica-mixed concrete panels, which are lightweight as a whole and have a high bending elastic modulus, which can prevent large coincidence effects, and the fired rigid plate-like body has a tile-like shape. Since it is possible to have a certain appearance, it can be put into practical use as it is without applying any finishing material.
