Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic cross-sectional view illustrating the basics of the soundproof panel of the present invention. In order from the inside (B) to the outside (C) toward the sound source (A), a flameproof tarpaulin sheet (1), a plate-shaped sound absorbing material as a glass wool molded body (2), and a sound insulation sheet (3) A panel body is constructed by arranging a flameproof tarpaulin sheet (1) and a sound insulating sheet (3), and enclosing a plate-shaped sound absorbing material (2) inside a bag-shaped case body (4). This panel body is used as a soundproof panel (10).

Here, the flame-retardant tarpaulin sheet (1) of the present invention is known as "tarpaulin", which was made by coating canvas with tar to make it waterproof, which was used as a waterproof sheet on ships in the old days. However, at present, composite sheets are made by sandwiching polyester or other fibers with soft synthetic resin films. In addition, it has flame retardant properties, that is, it is difficult to burn, has self-extinguishing properties, and has excellent strength and waterproof properties.

The flameproof tarpaulin sheet (1) of the present invention is available as a commercially available product and is essentially different from porous sheets used in conventional soundproof panels and sound-absorbing and sound-insulating panels. Furthermore, due to the above-mentioned characteristics of strength, waterproofness, and flameproofing properties, it can be used for panel bodies both outdoors and indoors. In the structure of the panel body of the present invention, the combination of the sound absorbing material (2) and the sound insulation sheet (5) provides excellent sound insulation performance.

In the soundproof panel (10) of the present invention, the plate-shaped sound absorbing material (2) must be a molded body of glass wool. The glass wool molded article of the present invention has excellent sound absorption properties. For example, by using a board-shaped high-density glass wool with a glass fiber density of 35 Kg/m ³ or more, preferably around 40 Kg/m ³ and a thickness of 45 to 55 mm, the sound absorption coefficient data obtained by the reverberation chamber method can be obtained. The measured value is a sound absorption coefficient of 0.9, that is, a sound absorption performance of 0.9M. A preferred example of the plate-shaped sound absorbing material (2) as a glass wool molded body is one in which glass wool is simply wrapped and finished with glass cloth. Alternatively, the product may be wrapped in a bag made of a soft film such as polyethylene after being packaged in glass cloth.
The sound insulation sheet (3) placed on the outside (C) with respect to the sound source (A) plays the role of reflecting sound inward (B), and is a conventionally known commercially available sheet. can be used. Preferably, a sheet body containing a lead material is exemplified.

To give a specific example, in the panel body of the soundproof panel (10) of the present invention, as the flameproof tarpaulin sheet (1), a 1 mm thick flameproof KT-1000E: Kanbou, as the plate-shaped sound absorbing material (2), 50 mm thick glass wool board (density 40 Kg/m ³ ): Paramount Glass Industries, 1 mm thick F-100: Kanbou can be cited as an example of the sound insulation sheet (3).

In the soundproofing panel (10) of the present invention, the flameproof tarpaulin sheet (1) and the soundproofing sheet (3) are used as a bag-like case body (4), and a plate-like sound absorbing material (2) is placed inside the case body (4). ), but the bag-like case body (4), for example in the configuration example shown in Fig. 1, has a flameproof tarpaulin sheet (1) and a sound insulation sheet ( 3) may be formed by suturing them, or may be formed by bonding them with an adhesive at their mutually overlapping parts. Alternatively, it may be joined using a hook-and-loop fastener as described later to form a bag shape. The same applies to both sides of the case body (4).

Furthermore, on the inner surface of the bag-like case body (4), rubber belt materials for self-supporting reinforcement of the soundproof panel (10) are placed, for example, on the side surfaces of the plate-like sound absorbing material (2), or on the front and back sides. may be arranged. As the rubber belt material, a trill rubber-based material having a multilayer structure and excellent tensile strength is exemplified. For example, commercially available products include Polybelt (registered trademark: Nitta). Such a rubber belt material may be attached and fixed with an adhesive or may be sewn together.

The bag-shaped case body (4) is made of a flame-retardant tarpaulin tote (1) and sound insulating material that is made to fit as closely as possible to the front, back, side, and upper and lower end surfaces of the plate-shaped sound absorbing material (2) to be delivered to the bag-shaped case body (4). The sheet (3) may be provided with a hook-and-loop fastener part or a hook part (bracket part) for locking with a string so that a plurality of soundproof panels (10) can be combined and connected to each other. In order to arrange the hook and loop fastener part, the hook surface and the loop surface that make up the hook and loop fastener part must be placed on either the front and back surfaces, the left and right sides, or even the top and bottom end surfaces, or even both, of the case (4). You can make money as you see fit. Alternatively, an extension section may be provided from the case body (4) by extending the ends of the flameproof tarpaulin sheet (1) and/or the sound insulation sheet (3), and the hook-and-loop fastener component may be arranged on this extension section.

For example, in the examples shown in FIGS. 2 and 3, in the two pairs of soundproof panels (10), the long side surface of one case body (4A) has a hook surface (5H ), and a loop surface (5L) is provided on the extending piece (6) of the other case body (4B). The hook surface (5H) and loop surface (5L) that make up these hook-and-loop fastener parts (5) may be attached with adhesive or stitched at the site where soundproofing is required, or they may be attached in advance at a factory etc. You can prepare it for installation.

When using the case body (4A) (4B), as illustrated in FIG. A system will be formed.

The sides of FIGS. 4 and 5 show horizontal connection and vertical connection between three soundproof panels.

The case body (4A) (4C) is provided with a hook surface (5H), and the case body (4B) is provided with a loop surface (5L) on the upper and side extension portions (6). . By using these case bodies (4A), (4B), and (4C), for example, as shown in FIG. A simple soundproof wall section will be constructed.

In the above example, in order to make it easier to understand the soundproofing panel of the present invention and the soundproofing system using the same, the combination of case bodies (4A) (4B) and case bodies (4A) (4B) (4C) will be explained. , shows a case where the hook surface (5H) and loop surface (5L) that constitute the hook-and-loop fastener part (5) are arranged in separate case bodies; The extension section (6) on which these are arranged may be arranged in advance on a single or specific soundproof panel. Of course, it may be placed as appropriate at indoor or outdoor sites.

In addition, in the soundproofing panel (10) of the present invention, the soundproofing system is installed at appropriate locations on the sides and upper and lower ends of the case body (4) to make it stronger and increase its independence, for example, as shown in the figure. It is also considered to provide a hook portion (bracket portion) at the location (F) shown in 6 to enable connection with a string (rope).

FIGS. 7 and 8 illustrate the soundproof panel system of the present invention installed outdoors. In the example of FIG. 7, a 1.5 m high soundproof wall is constructed, and as shown in FIG. 8, two layers are stacked to form a 3 m high soundproof wall.

Furthermore, FIG. 9 shows an example in which a small room is configured to be useful for protecting privacy in an evacuation area or the like. For example, by using nine soundproof panels with a width of 910 mm and a height of 1500 mm, a 3-tatami room can be created. The entrance/exit is one panel wide. You can easily create 4.5 tatami mats with 11 panels, 6 tatami mats with 13 panels, and 8 tatami mats with 15 panels.

In the above specific example, in order to ensure the independence of the panel system, for example, in the case of a flat wall configuration as shown in FIGS. 7 and 8, it may be supported with a steel pipe assembly, or in the case of the example shown in FIG. Also, a C-shaped channel made of resin or metal may be fitted and combined in the panel grounding portion.

The soundproof panels of the present invention can be used not only for large panels as shown in Figures 7 to 9, which can be used for partitions and small rooms at construction sites, factories, event venues, and evacuation sites, but also for office work. Alternatively, it can be used as a small partition or partition as appropriate, such as to protect privacy at a consultation desk in a public institution.
