Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a soundproof wall installed around a noise source such as a railway, a road, and a mechanical facility, and further relates to a soundproof panel used for the soundproof wall.

[0002]

[Prior art]

 As shown in FIG. 6, a sound absorbing material 19 such as glass wool is filled in a conventional soundproof wall installed around a noise generating source such as a railway, a road, and mechanical equipment to prevent the diffusion of noise. .. Were mounted on a concrete wall C in general.

[0003] In recent years, there are many soundproof walls using lightweight and inexpensive ceramic sound absorbing plates. As an example, in the soundproof wall shown in FIG. 7, an L-shaped piece 22 is fixed to a concrete wall C by a hole-in anchor 21 which is driven at a predetermined interval. A long C-shaped channel 23 is fixed by bolts 24 and nuts 25. The ceramic-type sound absorbing plate 12 is fixed by a screw 26 with a washer with the back surface abutting the C-shaped channel 23.

[0004]

[Problems to be solved by the invention]

 However, since the metal panel 20 as shown in FIG. 6 is heavy, it takes labor and cost for transportation and construction. Further, since such a metal panel 20 has a small dimensional variation, it may be troublesome and costly to cut and process the metal panel 20 in accordance with the soundproofing work range, and when the metal panel 20 is made of iron, The cut surface will rust.

On the other hand, in the soundproof wall shown in FIG. 7, since the ceramic sound absorbing plate 12 is not reinforced at all, it is easily broken. Also, since no makeup is applied to the outside of the sound absorbing plate 12, the appearance is not good. Further, since the sound absorbing plate 12 must be fixed to the concrete wall C with the hole-in anchor 21, the bolt 24, the nut 25, and the screw 26, labor and cost for construction are required.

[0006] The present invention has been made in view of such circumstances, and a purpose thereof is to provide a light, good-looking, highly dimensionally variable, and sound-absorbing plate that is hardly cracked. The point is to propose a soundproof panel that does not require much labor and cost for construction, and a soundproof wall using the same.

[0007]

[Means for Solving the Problems]

 That is, the soundproof panel according to the present invention includes a lattice plate, and a sound absorbing plate disposed on one side of the lattice plate.

This soundproof panel is relatively light because the lattice plate is used as a reinforcing base of the sound absorbing plate, and is less likely to be broken even if the sound absorbing plate is ceramic-based. Also, if this soundproof panel is assembled at the factory and the soundproof panel is installed so that the grid plate faces the wall at the site, the internal space of the grid plate will function as an air layer on the back side of the sound absorbing plate, and the soundproofing effect will be high. A simple soundproof wall can be constructed easily.

Further, it is preferable that the lattice plate of the soundproof panel is formed by fitting the cuts of a plurality of bars provided with cuts at predetermined intervals with each other.

[0010] If the lattice plate is formed by fitting the cuts of a plurality of rods together as described above, the assembling process of the lattice plate is easy, and the length of the rods is varied. If this is done, the size can be easily adjusted to the soundproofing work area without cutting the grid plate by changing the length of the bar. Furthermore, by changing the number and interval of the bars, the volume of each internal space of the lattice can be adjusted, and the soundproof performance of the soundproof panel can be improved.

Further, it is desirable to arrange a punching metal on the outer surface of the sound absorbing plate of such a soundproof panel.

By arranging the punching metal on the outer surface of the sound-absorbing plate in this way, the ceramic sound-absorbing plate, which is weak against impact, is protected from the outside, and the durability of the soundproof panel is increased. , Good looking.

On the other hand, the soundproof wall according to the present invention includes a plurality of guide members fixed to the wall surface in parallel with each other, and a soundproof panel described above between the adjacent guide members. It is fitted so that it does.

Since the soundproof wall has a structure in which the soundproof panel is mounted on the wall surface only by the guide material, the work and the cost of the construction are more complicated than those in which the sound absorbing plate is fixed at several places as shown in FIG. Can be greatly reduced.

[0015]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description, the same elements will be denoted by the same reference symbols, without redundant description.

FIG. 1A is a partially cutaway perspective view showing an embodiment of a soundproof wall, in which soundproof panels 10, 10,... Are fixed to guide members G, G,. … Is shown. The guide material G is a steel material having a hat-shaped cross section as shown in FIG. 1 (b), and is fixed to the concrete wall C at several places by anchor bolts B. The soundproof panel 10 is mounted on the concrete wall C so as to be dropped and fitted between the adjacent guide members G, G.

The soundproof panel 10 includes a lattice plate 11, a sound absorbing plate 12 disposed on the outer surface of the lattice plate 11, and a punched metal plate further disposed on the outer surface of the sound absorbing plate 12. 13 and angle members 14, 14,... That collectively restrain the lattice plate 11, the sound absorbing plate 12, and the punched metal plate 13 from four sides.

As shown in FIG. 2, the lattice plate 11 is a metal flat bar 11 a, which is a bar material arranged in parallel in the vertical direction, and is arranged in parallel in the horizontal direction so as to be orthogonal to these. It is constituted by combining metal flat bars 11b, 11b,. The flat bars 11a, 11b are provided with cuts 11c, 11c,... At predetermined intervals, respectively. Can be assembled.

At both ends of each of the flat bars 11a and 11b, fixed portions bent at right angles are formed. A screw hole 11d is formed in each fixing portion, and a screw hole 14a is also formed in each angle member 14, so that the screw hole 14a and the screw hole 11d are aligned to mount the screw 15. By screwing, the sound absorbing plate 12 and the perforated metal plate 13 can be reliably restrained in a state of being superimposed on the lattice plate 11.

Such a soundproof panel 10 is relatively light because the lattice plate 11 is used as a reinforcing base of the sound absorbing plate 12, and is hard to be broken even if the sound absorbing plate 12 is of ceramic type. In addition, if the flat bars 11a and 11b are prepared in various lengths, and the soundproof panel 10 is assembled by appropriately selecting the flat bars 11a and 11b according to the soundproofing work area, the soundproof panel 10 can be assembled in accordance with the soundproofing work area. There is no need for cutting. Then, as shown in FIGS. 1A and 1B, when the soundproof panel 10 is installed with the lattice plate 11 facing the concrete wall C, the internal space A of the lattice plate 11 is Since it functions as a layer, a soundproof wall with high soundproofing effect can be easily constructed. Further, at this time, by changing the combination interval between the flat bar 11a and the flat bar 11b, the volume of the internal space A of the lattice plate 11 can be adjusted, and the soundproof performance of the soundproof wall can be enhanced.

Further, since the perforated metal plate 13 is provided on the outermost surface of the soundproof panel 10, the sound absorbing plate 12 is prevented from cracking while noise is absorbed by the sound absorbing plate 12 through the holes. , And aesthetic appearance can be improved. The punched metal plate 13 can be omitted when the sound absorbing plate 12 has high strength. Further, since the soundproof panel 10 is mounted on the concrete wall C with only the guide material G, the soundproof wall can be easily constructed.

The soundproof panel 10A shown in FIG. 3 is different from the soundproof panel 10 of FIG. 2 in that fixed portions are not formed at both ends of the vertical flat bar 11a, and the punched metal plate 13 and the upper and lower angle members are not provided. 14 and 14 in that a metal box body 16 having left and right sides opened and a flat bar 17 for holding right and left are added. In other words, the sound absorbing plate 12 is disposed on the outer surface of the lattice plate 11 and is then comprehensively constrained by the metal box 16 so that the sound absorbing plate 12 is securely held on the outer surface of the lattice member 11. Is reinforced. The outer surface of the metal box 16 is a punching metal with a large number of holes formed therein, and plays the same role as the punching metal plate 13 of the soundproof panel 10 in FIG. Reference numeral 18 denotes a hook rod for preventing the lattice body 11 and the sound absorbing plate 12 from wobbling inside the metal box 16. The screw holes 17a of the flat bar 17 are for screwing the screw so as to match the screw holes 11d of the fixing portion of the flat bar 11b of the lattice plate 11. Such a soundproof panel 10A is also mounted on the concrete wall C in the same manner as shown in FIG. 1 to form a soundproof wall.

The soundproof panel 10 B of the soundproof wall shown in FIG. 4A differs from the soundproof panel 10 of FIG. 2 in the presence or absence of the perforated metal plate 13 and the structure of the lattice plate 11. As shown in FIG. 4B, the lattice plate 11 of the soundproof panel 10B is formed by fitting fitting portions 11e of small-width lattice plate pieces 11A and 11B integrally formed of a synthetic resin such as polypropylene. Is done. Of course, the lattice pattern of the lattice plate 11 is not limited to this, and may be, for example, the one shown in FIG.

The present invention is not limited to the above embodiment, and should be implemented with appropriate modifications without departing from the spirit of the present invention. For example, the material and dimensions of the lattice plate and the sound absorbing plate are appropriately determined according to the actual situation at the site.

[0025]

[Effect of the invention]

 As described above, the soundproofing panel according to claim 1 is relatively light because the lattice plate is used as a reinforcing base of the sound absorbing plate, and is hardly cracked even if the sound absorbing plate is of ceramic type. Also, if this soundproof panel is assembled at the factory and the soundproof panel is installed so that the grid plate faces the wall at the site, the internal space of the grid plate functions as an air layer behind the sound absorbing plate A soundproof wall having a high soundproofing effect can be easily constructed.

Further, according to the soundproof panel of the second aspect, it is easy to assemble the grid plate, and if the length of the bar is varied, the grid plate can be changed by changing the length of the bar. The size can be easily adjusted to the range of soundproofing work without cutting. Further, by changing the number and interval of the bars, the volume of each internal space of the lattice body can be adjusted, and the soundproof performance of the soundproof panel can be enhanced.

Furthermore, according to the soundproofing panel of the third aspect, the ceramic soundproofing plate which is vulnerable to impact is protected from the outside, so that the durability of the soundproofing panel is improved and the appearance is good.

On the other hand, the soundproof wall according to claim 4 has a structure in which the soundproof panel is mounted on the wall only by the guide member, and therefore, as compared with a structure in which the sound absorbing plate is fixed at several places as shown in FIG. The labor and cost of construction can be greatly reduced.
