JP-3255748-U - Sound-absorbing panels

Abstract

[Problem] To provide a sound-absorbing panel that maintains the sound-absorbing properties of a porous sheet while achieving a beautiful finish. [Solution] The device comprises a plate portion 11 having a core material 111 made of high-density glass wool and a porous sheet 112 disposed on the surface of the core material 111, and an edge portion 12 disposed on the edge of the plate portion 11. The porous sheet 112 is not adhered to the core material 111, and its edge is fixed by the edge portion 12. The edge portion 12 includes a base portion 121 disposed along the end face of the plate portion 11, and a pressing portion 122 attached to the base portion 121 that presses and holds the edge of the porous sheet 112 between itself and the base portion 121. The base portion 121 has a receiving portion 121a into which the pressing portion 122 fits, and an insertion portion 121c connected to the bottom of the receiving portion 121a. The side edge of the porous sheet 112 wraps around from the outer edge side of the receiving portion 121a inward, passes through a through hole 121b, and extends to the insertion portion 121c, and is fixed by the pressing portion 122.

Description

This invention relates to a plate-shaped sound-absorbing panel that can be installed in buildings. Traditionally, in the interiors of buildings such as halls, studios, conference rooms, and offices, sound-absorbing materials have been installed on walls and ceilings to adjust reverberation time and reduce noise. Sound-absorbing panels made of porous materials such as glass wool and rock wool are widely used as such sound-absorbing materials. For example, Patent Document 1 proposes a soundproofing panel in which surface materials are bonded to both sides of a frame structure consisting of vertical, upper, and lower frames, and a laminate made of metal foam and a sound-insulating sheet is placed in the hollow space between the surface materials. This soundproofing panel achieves high soundproofing across a wide frequency range by combining the sound-absorbing effect of the metal foam with the sound-insulating effect of the sound-insulating sheet. Publication No. 7-17684 This is a perspective view of a sound-absorbing panel according to an embodiment of the present invention.This is a cross-sectional view of a sound-absorbing panel according to an embodiment of the present invention.This is an exploded cross-sectional view of the main part of a sound-absorbing panel according to an embodiment of the present invention. The embodiments for carrying out this invention (hereinafter referred to as "embodiments") will be described in detail below with reference to the attached drawings. In the following description, identical or similar components will be denoted by the same reference numerals, and redundant explanations will be omitted or simplified. Furthermore, descriptions of directions such as up, down, left, and right in the following description are based on the directions shown in each drawing and do not limit the directions in actual use. [Overall configuration of the sound-absorbing panel] Figure 1 is a perspective view of a sound-absorbing panel 10 according to an embodiment of the present invention. Figure 2 is a cross-sectional view of the sound-absorbing panel 10. The sound-absorbing panel 10 is a plate-shaped panel installed on the ceiling or walls of a building for the purpose of adjusting the reverberation time and reducing noise within the building's interior. The sound-absorbing panel 10 can be used, for example, as an interior material such as a ceiling panel, wall panel, vertical louver, baffle sound-absorbing panel, or sound-absorbing partition panel in buildings such as halls, studios, conference rooms, and offices. As shown in Figures 1 and 2, the sound-absorbing panel 10 comprises a plate portion 11 and an edge portion 12 positioned at the edge of the plate portion 11. [Plate part 11] The plate portion 11 is a flat plate-shaped member that forms the main body of the sound-absorbing panel 10, and has a core material 111 and a porous sheet 112 that is placed on the surface of the core material 111. In this embodiment, the porous sheet 112 is placed only on the surface of the sound-absorbing panel 10, but it may be placed on both the front and back surfaces. (Core material 111) The core material 111 is a plate-shaped member made of high-density glass wool. The high-density glass wool constituting the core material 111 is made by forming glass fibers into a plate shape and bonding them with a binder such as phenolic resin (phenolic resin-mixed glass fiber board), and has excellent sound absorption properties. The density of the core material 111 is, for example, 100 kg/ m³ to 150 kg/ m³ , preferably 100 kg/ m³ to 130 kg/ m³ . By setting the density of the core material 111 to 100 kg/ m³ or more, sufficient sound absorption performance and rigidity can be ensured. Furthermore, by setting the density of the core material 111 to 150 kg/ m³ or less, the overall weight of the panel can be reduced. The thickness of the core material 111 is set appropriately according to the application of the sound-absorbing panel 10. For example, the thickness of the core material 111 can be set within a range of 15 mm to 60 mm. In this embodiment, the thickness of the core material 111 is 15 mm. By setting the thickness of the core material 111 to 15 mm, a thin sound-absorbing wall panel can be realized, allowing for effective use of limited indoor space. The planar dimensions of the core material 111 can be, for example, up to 900 mm x 1800 mm. In this embodiment, the planar shape of the core material 111 is a square with sides of 600 mm. However, the planar shape of the core material 111 is not limited to a square; it can be any shape such as a rectangle, circle, ellipse, polygon, etc. Figure 3 is an exploded cross-sectional view of the main part of the sound-absorbing panel 10. As shown in Figure 3, the end face (side surface) of the core material 111 has an insertion hole 111a and an insertion hole 111b that extend from the end face side to the inside of the core material 111. (Insertion hole 111a) The insertion
