【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall perspective view of a soundproof panel according to a first embodiment of the present invention. 2 is a transverse sectional view taken along the line II-II shown in FIG. 1, and FIG. 3 is a longitudinal sectional view taken along the line III-I II shown in FIG. As shown in FIG. 2 and FIG. 3, the soundproof panel 1 of this embodiment includes glass wool 2 as a soundproof substrate layer, front and rear panels 3 and 4 for covering both front and back surfaces of the glass wool 2, and front and rear panels 3. 4, upper and lower horizontal frames (mounting frames) 5 and vertical vertical frames (mounting frames) 6 that are attached to the glass wool 2 from above and below, and a cloth cloth (surface material) attached to the front and rear panels 3 and 4. 7 and a stop metal fitting (fixing metal fitting) 8 for fixing the cloth cloth 7 to the upper and lower horizontal frames 5 and the left and right vertical frames 6.

The glass wool 2 is obtained by melting glass, blowing high-pressure air or steam onto the glass to make fibers, and collecting the fibers into a cotton shape, which is a typical porous material. Since the glass wool 2 has a large sound absorbing effect on sounds in the middle and high range, it is used when it is desired to obtain a soundproofing effect on these ranges. Also, since the sound absorbing performance and thus the soundproofing performance of the glass wool 2 vary depending on the density and thickness of the fiber layer of the glass wool 2, the density and thickness should be appropriately selected and used according to the individuality of the room and the purpose of use. Be done.

The front and rear panels 3 and 4 are made of gypsum board, hard board, MDF, plywood, or metal, and have the same or different front and rear thicknesses. The front and rear panels 3 and 4 are attached to the front and rear surfaces of the glass wool 2. In this case, by creating a double wall structure in the front and rear panels 3 and 4, great soundproofing performance in the midrange can be obtained.

The upper and lower horizontal frames 5 and the left and right vertical frames 6 are formed in horizontally long and vertically long prisms, respectively, and are attached so as to surround the glass wool 2 to which the front and rear panels 3, 4 are attached. A long groove (fixed groove) 9 is formed on the front and rear surfaces of the upper and lower horizontal frame 5 over the entire surface in the horizontal direction at the center in the vertical direction. Similarly, on the front and rear surfaces of the left and right vertical frame 6, a long groove 9 is formed at the center in the left and right direction over the entire surface in the vertical direction.

The cloth cloth 7 is used as a surface material, and since the soundproof panel 1 also serves as an interior material, a decorative pattern is applied.

The stopper 8 is bent to have a U-shape. The stopper 8 is formed between the end face and the long groove 9 so that one side bent is inserted into the long groove 9 of the upper, lower, left and right frames, and the other side is along the end face facing the long groove 9. In addition, the holding end 10 of each frame is fitted and the holding end 10 is held.

Next, a process of assembling the soundproof panel 1 will be described.

First, the front and rear panels 3 and 4 are attached to the front and back surfaces of the glass wool 2. Then, the upper and lower horizontal frames 5 and the left and right vertical frames 6 are attached to the glass wall 2 to which the front and rear panels 3 and 4 are attached so as to sandwich the glass wall 2. Further, the cloth cloth 7 is laid on the front surface of the front panel 3, and the four side ends of the cloth cloth 7 are inserted into the long grooves 9 of the upper and lower horizontal frames 5 and the left and right vertical frames 6, respectively. Then, the fasteners 8 are fitted one by one into the long grooves 9 while tensioning the cloth cloth 7 so that no wrinkles are formed on the surface of the cloth cloth 7, and the cloth cloth 7 is fixed in order from one end. The soundproof panel 1 of this embodiment is obtained by performing the same steps on the back surface side.

The soundproof panel 1 obtained in this manner can be assembled uniformly before the cloth cloth 7 is attached, and thus is inexpensive. Moreover, since the cloth cloth 7 is attached by the fastener 8, not only can the cloth cloth 7 be easily replaced, but it can also be applied to a wide variety of commercially available cloth cloths and so-called wallpaper sheets. it can. Therefore, the variation can be effectively used.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5, 6 and 7. The soundproof panel 21 of the second embodiment is similar to the first embodiment in that the glass wool 22 as a soundproof base material, the front and rear panels 23 and 24 attached to the front and rear surfaces of the glass wool 22, and the upper and lower laterals for sandwiching them. The frame 25 and the left and right vertical frames 26, a cloth cloth 27 as a surface material, and a stopper 28 for fixing the cloth cloth 27. The difference from the first embodiment is the positions of the long grooves 29 formed in the upper and lower horizontal frames 25 and the left and right vertical frames 26, and the shape of the stopper 28.

That is, in the second embodiment, the long grooves 29 are formed on the upper and lower surfaces of the upper and lower horizontal frames 25, respectively, and on the side surfaces of the left and right vertical frames 26. The stopper 28 is formed in a rod shape, and is embedded in the long groove 29 so as to be fitted therein.

When attaching the cloth cloth 27, the four side ends of the cloth cloth 27 are inserted into the long grooves 29 of the upper and lower horizontal frames 25 and the left and right vertical frames 26, respectively, as in the first embodiment. Then, the stopper 28 is fitted into the long groove 29 from above. Unlike the case of the first embodiment, the soundproof panel 21 to which the cloth cloth 27 is attached in this manner has the advantage that the stopper 28 does not appear on the surface and the appearance is further improved (FIGS. 4 and 8). See).

In the two embodiments described above, the upper and lower horizontal frames 5 and the left and right vertical frames 6 are attached so as to surround the glass wool 2 which is the soundproof base material layer, and the long groove 9 for fixing is formed in these. However, for example, using a rigid plywood or the like for the soundproof base material layer, the long groove for fixing is directly formed on this, and as described above, the long groove and the fasteners directly formed on this soundproof base material layer. It is also possible to clamp and fix the cloth cloth with and.

Although glass wool is used as the soundproof base material layer in the embodiment, for example, rock wool or sponge, which is another porous material, or another sound absorbing material, or an air layer may be used. Good. Although cloth cloth is used as the surface material in the embodiment, leather, wallpaper sheet, vinyl sheet or the like may be used. Furthermore, in the embodiment, long grooves are formed in the upper, lower, left, and right mounting frames, and the cloth cloth is clamped and fixed by the horizontally and vertically long or rod-shaped stoppers that are fitted into the mounting frames. A plurality of mounting holes may be formed in the mounting frame at opposite positions, and the cloth cloth may be sandwiched and fixed by the inner surface of the mounting hole and the stopper fitting fitted therein. In addition, the detailed configuration can be appropriately changed without departing from the spirit of the present invention.
