央空隙１３は凹凸の激しい空隙となされている。この中
央空隙１３には、必要に応じて、ロックウールやガラス
ウール等の吸音材が充填されることがある。A large number of grooves 12 are formed longitudinally and laterally at predetermined intervals in the stepped-down portion 16 of the front and rear plates 1, and as a result, the central void 13 of the front and rear plates 1 is made into a highly uneven void. The central void 13 may be filled with a sound absorbing material such as rock wool or glass wool, if necessary.
なお、第３図（イ）〜（ハ）に、溝１２の変形例を示
す。3A to 3C show modified examples of the groove 12.
（実施例の作用） 次に実施例板の作用を説明する。(Operation of Embodiment) Next, the operation of the embodiment plate will be described.
防音板に当った音は、遮音シート３によって遮断された
り、凹凸の激しい中央空隙１３内で、反射・減衰させら
れる。The sound that hits the soundproof plate is blocked by the sound insulating sheet 3 or is reflected / attenuated in the central air gap 13 where the unevenness is severe.
（考案の効果） この考案は前記の如き構成によって以下の如き効果を奏
する。(Effect of the Invention) The present invention has the following effects due to the configuration as described above.
中央空隙を形成する、前板又は後板の部分に、所定間
隔で縦・横に形成された多数の溝によって、中央空隙が
凹凸の激しいものとなされているので、この凹凸の激し
い中央空隙内で音を反射・減衰させることが出来、その
結果、効果的に防音を行なうことが出来る。The front and back plates that form the central space are made uneven by the large number of grooves that are formed vertically and horizontally at predetermined intervals. The sound can be reflected and attenuated with, and as a result, sound can be effectively prevented.
中央空隙を形成する、前板又は後板の部分には、縦横
に多数の溝を形成して凹凸の激しい中央空隙を構成する
ようにしたものであるから、換言すれば、前板又は後板
に縦横の溝を形成するといった簡単な作業によって、凹
凸の激しい中央空隙を形成することが出来るので、防音
板を安価に製作することが出来る。In the part of the front plate or the rear plate that forms the central space, a large number of grooves are formed in the vertical and horizontal directions to form a central space with severe irregularities.In other words, the front plate or the rear plate. Since the central void having severe irregularities can be formed by a simple operation such as forming vertical and horizontal grooves in the, the soundproof plate can be manufactured at low cost.
段落ち部においては前板及び後板が直接に相互に接触
しないものであるから、即ち、前板と後板とが直接に当
接・接触する部分が少ないので、前板と後板との間での
音の伝播が効果的に阻止され、その分だけ防音効果を高
めることが出来る。In the stepped-down portion, the front plate and the rear plate do not directly contact each other, that is, since there are few parts where the front plate and the rear plate directly contact and contact with each other, the front plate and the rear plate are Propagation of sound between the areas is effectively blocked, and the soundproofing effect can be increased accordingly.
