Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent sound-insulating panel, an apparatus used therefor, and a method for assembling a transparent sound-insulating panel,
In particular, a transparent sound insulation panel and a sound insulation wall or a sound insulation wall standing on the side of a vehicle running path in an urban area, which can see through the outside to the extent that speeding up when running a car or train while maintaining the function of a sound insulation wall or sound absorbing wall. Device and a method for assembling such a transparent sound insulation panel.

[0002]

2. Description of the Related Art Conventionally, as is well known, a vehicle running path such as a highway or a railroad is provided with the above-described sound insulation wall or the like (hereinafter referred to as a sound insulation wall) on its side, so that the vehicle is The sound generated when passing is not leaked to the outside.

[0003]

However, the conventional vehicle traveling path surrounded by a sound insulation wall is dark in its entirety, and it gives a feeling of pressure to a person on board the vehicle, and the scenery outside can be seen through the sound insulation wall. I can't do it and I have poor transparency. In order to solve this, it was proposed to provide a transparent sound insulating wall made of plastic.

However, the sound insulation wall has a reduced transparency due to dust, dirt, or stains caused by wind and rain, making it difficult to see the outside scenery and significantly reducing the see-through property. Also,
Along with this, the whole becomes darker, and there is a feeling of pressure.

An object of the present invention is to improve the see-through property by allowing the outside scenery to be seen through on a vehicle traveling path provided with a sound insulation wall, and to provide a feeling of openness.

[0006]
