Description

Frame For Transparent Noise Keeping Panel

The present invention relates to a frame, and more particularly, to a frame used for manufacturing a transparent soundproof plate is fixed to the edge of the transparent panel, relates to a transparent soundproof plate frame having a structure that can minimize the elastic strain due to wind load.

As is well known, sound proof walls are walls that are thickened or made of soundproof material to block outside noise or room acoustics. Such a soundproof wall is a wall installed to block sound waves with a wide wall to reduce the volume of sound transmitted to the rear of the wall, and is mainly installed between noise transmission paths for the purpose of blocking noise.

Here, if there is a wall between the place where the noise is generated and the listener, the sound wave is transmitted beyond the wall, so the distance of the sound wave is extended, which reduces the size of the transmitted sound, and the soundproof wall is a special material that can block or absorb the sound. Made of material, the volume of the transmitted sound can be further reduced.

On the other hand, the soundproof wall, in addition to the acoustic performance such as the scratch rate, transmission loss, etc., the structural performance against the wind pressure capable of withstanding strong winds such as typhoons should be secured. Tests and evaluation methods for evaluating the effect of sound insulation panels on wind loads are specified in EN 1794-1. The purpose of this standard is to provide a sound load between the sound insulation boards after wind loads have been removed or after the wind loads have been removed. The maximum strain is regulated to prevent leakage of noise due to crevices. Particularly, in the elastic deformation test, the soundproofing plate is installed on both sides in the width direction of the soundproofing plate so that the soundproofing plate does not move, and then the deflection of the soundproofing plate is placed for 30 minutes while evenly distributing the appropriate number of loads on the top of the soundproofing plate. Is carried out in a manner to measure. In this case, the test load is generally 1.5 times the design wind load, and the regulation value (elastic deformation amount) is set within 50 mm.
