Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed, for example, on both sides of a highway so that vehicle noise on the highway does not leak and propagate to surrounding private houses. The present invention relates to a structure for assembling a light-transmitting / sound-absorbing panel that can prevent reverberation from occurring.

[0002]

2. Description of the Related Art Conventionally, in order to prevent vehicle noise on an expressway from leaking to surrounding private houses, a soundproof wall such as an iron plate, an aluminum plate, or a gypsum board was installed on both sides of the expressway. If the height is low, it leaks to the surrounding area, so the height was increased. However, when the soundproof wall was raised, this time the light was blocked, and there were complaints from the surrounding private houses that the sunshine right was violated instead of vehicle noise. Therefore, recently, in order to prevent not only vehicle noise but also light, a soundproof wall in which a transparent plastic plate or the like is fitted has been used.

[0003]

However, in such a conventional soundproof wall, although the vehicle noise to the surrounding private houses can be blocked and the sunshine right can be guaranteed, the plastic plate has no sound absorbing effect. Since there is no such thing, it just bounces the sound, so the vehicle noise echoes inside the highway,
For the driver, there was a problem that vehicle noise caused stress, resulting in frustration and lack of concentration, leading to traffic accidents and fights.

In view of the above problems, the present invention provides a light-transmitting / sound-absorbing panel which can prevent the vehicle noise from reverberating inside the expressway while blocking the transmission of the vehicle noise to surrounding private houses and guaranteeing the sunshine right. It is an object of the present invention to provide an assembly structure of.

[0005]

In order to solve the above-mentioned problems, the structure for assembling a light-transmitting / sound-absorbing panel according to the present invention is mounted on one side of a frame member which surrounds four sides and has a thickness. It is configured to include a light-transmitting panel member that allows light to pass therethrough, and a light-transmitting sound-absorbing panel member that is mounted on the other surface of the frame member and that separates a space from the light-transmitting panel member and that transmits light and absorbs sound. .

According to the structure for assembling the light-transmitting / sound-absorbing panel having such a structure, not only the light-transmitting panel member that allows light to pass therethrough is provided on one side of the frame member, but also the space is separated from the light-transmitting panel member. By providing a light-transmitting sound-absorbing panel member that transmits light and absorbs sound on the other surface side of the member, the light-transmitting sound-absorbing panel member exerts a noise absorbing effect, so that it blocks vehicle noise on a highway and protects the sunshine. Along with the guarantee, it is possible to prevent the vehicle noise from being reflected in the highway that is blocked by soundproof walls on both sides.
