〔産業上の利用分野〕
本発明は鉄橋、橋、室壁の中材等における消音ならびに
通気性に優れた消音板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 deadening board that is excellent in sound deadening and air permeability for use in iron bridges, bridges, interior walls of rooms, etc.
消音板は、その形状によって音源の振動が消音板自身を
振動させる場合において、消音効果をあげることが困難
であった。そこで本発明は、板全体に網状の隙間を取っ
て共鳴するのを防ぎ、二枚の重なった網の間にバイブ状
の消音材を挟み込んだものである。Due to the shape of the muffling plate, it has been difficult to achieve a muffling effect when vibrations from a sound source cause the muffling plate itself to vibrate. Therefore, in the present invention, a mesh-like gap is provided throughout the board to prevent resonance, and a vibration-like sound deadening material is sandwiched between two overlapping meshes.
これによって消音板が振動する場合でも、共鳴によって
消音が阻害されることなく、消音効果があがるものであ
る。As a result, even when the sound deadening plate vibrates, the sound deadening is not inhibited by resonance, and the sound deadening effect is improved.
［従来の技術〕
従来この種の消音構造は、橋の場合それがコンクリート
で構成されるものは、それ自体が遮音効果を持ち、鉄橋
においてはその公共性が重視され消音構造をもたないも
のが多い。[Prior art] Conventionally, this type of sound-absorbing structure has been used in the case of bridges, which are made of concrete, which have a sound-insulating effect themselves, and in the case of iron bridges, where importance is placed on their public nature, they do not have a sound-absorbing structure. There are many.
従って鉄橋等は大きな騒音を伴い、列車が通るものは更
に大きな騒音を伴う。これらの音は干渉、共鳴によって
拡散、増幅される。Therefore, railway bridges and the like make a lot of noise, and those on which trains pass make even more noise. These sounds are diffused and amplified by interference and resonance.
本発明は、このような問題点を解決するために発案され

てこれをもう一方から同じ網状のもので挟み込んでなる
消音板である。The present invention was devised to solve these problems, and the surface is formed of a net having the necessary strength, and inside the net, cylindrical sound-deadening materials are arranged in the same direction. Here, the inner diameter of the cylinder is determined based on the wavelength of the sound to be muffled, etc., and the spacing between the cylinders is determined in consideration of the influence of wind, etc., and this is fixed. The sound deadening board is made by sandwiching this with the same net-like material from the other side.
本発明は前記のように、網とこれに挟み込まれた筒状の
消音材で形成されているので、通気性が良く消音材の形
状から筒の内部で音は干渉によって打ち消し合い、更に
筒自身の消音効果が加わり消音効果をあげるもので、風

音壁等の表面に使用すれば、大きな消音効果を得ること
ができる。As mentioned above, the present invention is made of a net and a cylindrical sound-deadening material sandwiched between the nets, so it has good ventilation, and due to the shape of the muffling material, the sound cancels each other out through interference inside the tube, and furthermore, the tube itself. It has a sound-dampening effect, and if used on the surfaces of iron bridges that are affected by wind, or sound-insulating walls used on railway lines, etc., a great sound-dampening effect can be obtained.
本発明を図示の実施について説明する。第１図において
（Ａ）は固定する柱、（Ｂ）は金網である。ただし外部
から力がほとんど作用しない場合は、強度の小さい網を
用いてもかまわない。ここで第２図のように筒状の消音
材（Ｃ）を前記の金網で挟み込み、等間隔で固定する。The invention will now be described with reference to illustrated implementations. In FIG. 1, (A) is a pillar to be fixed, and (B) is a wire mesh. However, if little external force is applied, a net with low strength may be used. Here, as shown in FIG. 2, the cylindrical sound deadening material (C) is sandwiched between the wire meshes and fixed at equal intervals.
ただし消音材の材質及び筒と筒との間隔、筒の大きさは
、前記したこと以外に風の影響等の諸条件を満たすもの

くい、すなわち浮力によって消音板が破壊されにくくな
る。更に音が消音板によって反射、共鳴することがない
ように、筒状の消音材（Ｃ）は軟らかなものを用いて、
振動を吸収するようにしたものである。これは以上の構
造から鉄橋における実施例である。However, the material of the sound deadening material, the spacing between the tubes, and the size of the tubes should satisfy various conditions other than those mentioned above, such as the influence of wind. Therefore, this structure makes it difficult for air pressure differences to occur due to wind, that is, the sound deadening board is difficult to be destroyed by buoyancy. Furthermore, in order to prevent the sound from being reflected and resonated by the sound deadening plate, the cylindrical sound deadening material (C) is made of soft material.
It is designed to absorb vibrations. This is an example of a railway bridge based on the above structure.
次に第３図は一般の遮音壁と併用した場合の実施例であ
る。これは遮音壁によって音の反射、干渉、拡散を抑え
るもので、これはバイブ消音板の通気性と強度を生かし
た実施例である。Next, FIG. 3 shows an example when used in combination with a general sound insulating wall. This is a sound insulating wall that suppresses the reflection, interference, and diffusion of sound, and this is an example of making use of the breathability and strength of the vibe sound deadening board.
以上のように、本発明によれば鉄橋等それ自体が振動す
るものの消音を可能にしたものであり、更に従来の遮音
壁だけでは十分な遮音効果のなかったものの表面に取り
付けることにより、騒音を大幅に抑えることのできるも
のである。As described above, according to the present invention, it is possible to muffle the sound of things that vibrate themselves, such as iron bridges, and furthermore, by attaching them to the surface of things where conventional sound insulation walls alone did not have a sufficient sound insulation effect, noise can be significantly reduced. This can be suppressed to .
またこのバイブ消音板は、構造が簡単で目的に合わせて
強度や消音能力、重量をきめることができ、比較的安価
なものから高価なものまで幅広い種類のものを作ること
ができる。Furthermore, this vibration muffling board has a simple structure, and its strength, muffling ability, and weight can be determined according to the purpose, and a wide variety of types can be manufactured, from relatively inexpensive to expensive ones.
