Problems solved by technology

[0008] However, if foam or rayon is used instead of glass fiber or asbestos as the sound-absorbing material filled between panel elements, since foam and rayon have a low melting point, they can serve as secondary causes of ignition and flame spread, thereby increasing the fire damage

Embodiment Construction

[0026] A detailed description of the present invention will be provided below with reference to the accompanying drawings.

[0027] The sound-absorbing panel 1 according to the present invention includes: a floor element 10 having a predetermined size; an intermediate layer 20 having a honeycomb structure with a predetermined thickness, which is composed of a plurality of cells having a honeycomb shape and mounted on the floor element 10; The porous plate member 30 has a plurality of holes 31 and is mounted on the middle layer 20 of the honeycomb structure; the side plate member 40 closes the sides of the bottom plate member 10 and the porous plate member 30.

[0028] The intermediate layer 20 of the honeycomb structure is fixed to the porous plate member 30 and the bottom plate member 10 with an adhesive.

[0029] Such as figure 1 with 2 As shown, around the four sides of the honeycomb structure layer 20 in the middle, the upper part of the side plate element 40 is fixed to the ...

Abstract

PURPOSE: A sound absorption panel is provided to isolate the diffusion of flames and to increase the sound absorption property by filling a coated honeycomb between a base plate and a perforated plate. CONSTITUTION: A base plate member(10) is formed in a plate shape with a certain size. A honeycomb(20) is formed by many honeycomb shaped cells and installed in the upper part of the base plate member with a certain thickness. A perforated plate member(30) is formed by a plate shape having many holes(31) and loaded on the upper part of the honeycomb. A side plate member(40) shields the perforated plate member and the base plate member, the honeycomb is located between the perforated plate member and the base plate member. Thereby, the sound absorption property is increased without a glass fiber, a rock wool or a foam.

Description

Technical field [0001] The present invention relates to a sound-absorbing panel, in particular to a sound-absorbing panel in which a honeycomb structure of a predetermined thickness, which replaces traditional sound-absorbing materials, is sandwiched between panels to prevent the rapid spread of flames in the event of a fire and improve the sound-absorbing effect And the durability of sound-absorbing panels. Background technique [0002] Generally, a traditional sound-absorbing panel includes two panel elements, an intermediate layer made of glass fiber and other sound-absorbing materials between the two panel elements, and a side panel element that closes the open side between the two panel elements. [0003] However, sound-absorbing materials such as glass fiber and asbestos are harmful to humans and the environment, and since glass fiber and asbestos are blown away by the wind, it cannot be used in places that require fresh and clean air. [0004] If glass fiber or asbestos is...
