前記従来防音板には以下の如き欠点があつた。
即ち、鉛板や、鉛粉を混入した軟質プラスチツク
シートは、重量が重く、運搬や施工が大変である
という欠点があつた。(Disadvantages of the Prior Art) The conventional soundproof board has the following disadvantages.
That is, lead plates and soft plastic sheets mixed with lead powder have the disadvantage that they are heavy and difficult to transport and install.
（考案の目的）
この考案は上記欠点を解消するためになされた
ものであつて、軽量の防音板を提供することを目
的とするものである。(Purpose of the invention) This invention was made in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a lightweight soundproof board.
（実施例）
以下にこの考案を図面に示す実施例に基づいて
説明する。(Example) This invention will be described below based on an example shown in the drawings.
第１図〜第３図に示す如く、枠体１と、その枠
体１の前後面に当てられた前後板２とによつて内
部３が中空となされ、この中空内部３に位置する
ようにして、多数の円錐形や角錐形の吸音突起４
が、その大径部において前後板２内面に設けら
れ、前側の吸音突起４の尖端部と、後側の吸音突
起４の尖端部とが相互に入れ違いとなされ、これ
ら吸音突起４の表面に多数の吸音小凹所５が形成
されている。吸音突起４の素材は、木・合成樹脂
等の金属以外のものである。 As shown in FIGS. 1 to 3, an interior 3 is made hollow by a frame 1 and front and rear plates 2 applied to the front and rear surfaces of the frame 1, and the interior 3 is positioned in the hollow interior 3. A large number of conical and pyramidal sound absorbing protrusions 4
are provided on the inner surface of the front and rear plates 2 at their large diameter parts, and the tip of the sound-absorbing protrusion 4 on the front side and the tip of the sound-absorbing protrusion 4 on the rear side are interchanged with each other. A small sound-absorbing recess 5 is formed. The material of the sound-absorbing protrusion 4 is a material other than metal, such as wood or synthetic resin.
なお、第４図〜第６図に吸音小凹所５の変形例
を示す。 In addition, modifications of the small sound-absorbing recess 5 are shown in FIGS. 4 to 6.
（実施例の作用） 次に実施例板の作用を説明する。(Effect of Example) Next, the function of the example plate will be explained.
防音板に当つた音は、吸音体突起４によつて形
成された凹凸の激しい吸音空間内で、反射・減衰
させられ、また、吸音小凹所５内で反射・減衰さ
せられる。 The sound hitting the soundproof board is reflected and attenuated within the highly uneven sound-absorbing space formed by the sound-absorbing projections 4, and is also reflected and attenuated within the small sound-absorbing recesses 5.
（考案の効果）
以上の次第でこの考案によれば、従来と相違し
て、鉛板や、鉛粉を混入した軟質プラスチツクシ
ートを使用せず、木・合成樹脂等の金属以外の素
材からなる多数の吸音突起４によつて、音を吸収
するようにしたものであるから、重量が軽く、運
搬や施工が楽である。また、前側の吸音突起４の
尖端部と後側の吸音突起４の尖端部とが相互に入
れ違いとなされているので、即ち吸音突起４によ
つて凹凸の激しい吸音空間を簡単に形成すること
が出来るので、吸音を効率よく行なうことが出来
る。(Effects of the invention) As described above, according to this invention, unlike conventional methods, it does not use lead plates or soft plastic sheets mixed with lead powder, but is made of materials other than metal such as wood or synthetic resin. Since the sound is absorbed by the large number of sound-absorbing protrusions 4, it is light in weight and easy to transport and install. In addition, since the tip of the front sound-absorbing projection 4 and the tip of the rear sound-absorbing projection 4 are interposed with each other, it is possible to easily form a highly uneven sound-absorbing space with the sound-absorbing projection 4. Therefore, sound absorption can be carried out efficiently.
