Description
【考案の詳細な説明】 (産業上の利用分野) 本考案は、高速道路などの交通騒音公害を防止する防
音壁として使用される透明遮音パネルに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a transparent sound insulation panel used as a sound insulation wall for preventing traffic noise pollution such as a highway.
(従来の技術) 従来、騒音の激しい道路沿いに騒音防止などを目的に
設置される防音壁は、道路管理者側の交通騒音対策とし
て、吸音性を有しないプレキャストコンクリート遮音パ
ネルや金属製吸音型遮音パネルを、H形鋼などの支柱に
組み込んで障壁に形成している。(Prior art) Conventionally, noise barriers installed along roads with high noise levels for the purpose of preventing noise are used as precautionary measures against traffic noise by road managers. The sound insulation panel is built into a pillar such as an H-beam to form a barrier.
さらに、近年では、道路交通量の増大や道路周辺の市
街化によって、交通騒音公害も拡大の一途を辿っている
ため、道路防音壁の設置区間の増加や防音壁設置高さの
増大へと進んでいる。このような防音壁は道路内外から
の視環境の劣悪化を招く傾向にあるが、その対策として
は遮音パネルを透明化して重圧感の解消や周囲環境との
調和を図る改善も進められている。Furthermore, in recent years, traffic noise pollution has been steadily expanding due to an increase in road traffic volume and urbanization around the road. Therefore, the installation section of the road noise barrier and the height of the noise barrier installation are increasing. In. Such noise barriers tend to cause deterioration of the visual environment from inside and outside the road, but as a countermeasure, improvements have been made to make the sound insulation panels transparent to eliminate the feeling of heavy pressure and to harmonize with the surrounding environment. .

数多く生じている。(Problems to be Solved by the Invention) However, such a soundproof wall of the related art limits the noise source to be subjected to noise suppression to vehicles running on the road, and thus has a sound absorbing property such as a concrete panel. In addition to the sound insulation panel having no sound absorption panel, the metal sound absorption type sound insulation panel and the transparent sound insulation panel are not provided with sound absorption characteristics on the back side of the target road. For this reason, in places where the surrounding noise generated outside the road is large, there are many cases in which external noise is reflected on the back surface of the soundproof wall to promote noise pollution locally. Even if the noise from the corner target road is cut off, the reflected noise increases, and there are many cases where the noise problem cannot be actually solved.
本考案は、このような従来の防音壁のもつ機能的な欠
陥を解消させると共に、外部から見た景観調和対策など
にも有効な遮音パネルを提供しようとするものである。An object of the present invention is to solve such a functional defect of the conventional soundproof wall, and to provide a soundproof panel which is effective also for countermeasures for harmonizing scenery viewed from the outside.

両面に吸音性が付与されていることを特徴とする。(Means for Solving the Problems) The transparent soundproof panel according to the present invention includes a plate-shaped transparent sound-insulating member 2 and a peripheral edge of the plate-shaped transparent sound-insulating member 2, as shown in the drawings. A rubber packing material 3 for holding and fixing in a cushioning manner, and a frame-shaped frame 1 fitted and attached to the plate-shaped transparent sound insulation member 2 via the rubber packing material 3, and the frame-shaped frame Numeral 1 denotes an annular space 6 defined on the outer periphery of the packing material fitting portion, in which a porous sound absorbing material 5 having a sound absorbing property is stored and filled, and each of which is located on the front side and the back side of the transparent soundproof panel. At least a part of the side surface is formed by the perforated plate 4,
It is characterized in that sound absorption is provided on both sides.

拡散するのを防止させる方式を採用した。That is, the conventional sound insulation panel for a sound insulation wall has a structure in which the required acoustic properties of the sound insulation panel are given only to the noise source side and little consideration is given to noise from outside the road. In the invention, the front and back of the sound insulation panel is eliminated, and sound absorbing performance is incorporated on both sides of the frame-shaped frame body holding the plate-shaped transparent sound insulation plate, so that the noise energy reaching the installation surface of the sound insulation wall is absorbed by both sides of the sound insulation wall, A method was adopted to prevent noise energy from spreading in the direction of.

Can't expect. However, 1m to 2m for the wavelength band of the sound wave of the noise source
It has already been confirmed that by arranging a frame having a sound absorption performance in a frame shape on both sides around the sound insulation plate with a size of about, the apparent sound absorption characteristics as a sound insulation surface can be significantly improved, If a sound absorbing mechanism is assembled to the frame as described above along the inside of the periphery of both sides of the panel where the transparent sound insulating plate is fixed at the center of the frame-shaped frame which constitutes the sound insulating panel of the sound insulating wall by fixing the transparent sound insulating plate, This sound absorbing mechanism has an effect of capturing and eliminating incident noise energy, and reduces reflection of noise on the sound insulating surface.

い。The conventional idea of installing this type of soundproofing wall is to prevent the diffusion of noise generated on a specific road, and to give acoustic characteristics only to the noise source side, but the back of the soundproofing wall has reflection characteristics In many cases, even if the main noise is reduced by reflecting the noise from the surroundings, another noise is reflected and reaches, and the noise prevention effect cannot be sufficiently exhibited.
