Conventional soundproof walls are installed in a form that can not pass through the wind in consideration of noise blocking only. Such conventional sound barriers negatively affect the protection of the natural environment by blocking the flow of air as well as noise, causing ecological disconnection. In addition, since the entire area of the soundproof wall is subjected to wind resistance, when the soundproof wall is formed in consideration of the maximum wind speed in the region, the foundation of the soundproof wall becomes excessively large, and the cost of installing the soundproof wall per unit length is very high.

As can be seen in Figures 1 to 3, the ventilated soundproofing panel 100 according to the present invention has a curved wind path 110. The wind path 110 is to increase the sound insulation effect for the noise of the middle and high frequency band of more than 1000Hz as well as the noise of the frequency band less than 1000Hz. The curved portion of the wind passage 110 is preferably formed to be gently curved so that the wind can smoothly change the direction.

As the wind path 110 is preferably bent in the S-shape as can be seen in Figures 2 and 3. As such, when the wind path 110 is formed in an S shape, the direction of the wind can be smoothly changed, thereby reducing the volume or width of the straight path included in the straight path without increasing the wind resistance. The sound insulation performance against the noise of the high frequency band can be improved. Of course, the sound insulation performance for low frequency noise is also improved. As in the soundproof panel 100 shown in FIGS. 1 to 3, the volume of the wind path 110 included in the straight path in the front and rear direction perpendicular to the soundproof panel 100 is 0, that is, the volume of the straight path does not exist. It is preferable. More preferably, one wall surface in front of the wind path 110 is arranged in the same line as the other wall surface in the rear.

To the left and right of the wind passage 110 as described above, the resonance chamber 121 having a resonance hole 122 communicating with the wind passage 110 is disposed. The resonance chamber 121 is preferably arranged in double back and forth, as can be seen in Figures 2 and 3, in order to attenuate the noise of a wide frequency band through the resonance, the resonance chamber 121 is disposed in front and rear It is a good idea to make different internal volumes of the ones arranged on the sides. The same is true for the wind passage 110 disposed on both sides.

In some cases, the ventilation chamber 121 according to the present invention may be configured by arranging the resonance chamber 121 back and forth in three, four, five or more.

In the resonance chamber forming member 120 shown in FIGS. 2 and 3, two or more divider plates 123 are formed at intervals in the front-rear direction, and a space between the divider plates 123 is formed on the wind passage 110. By further forming a resonance hole 122 communicating with the passage 110, the resonance chamber 121 can be formed in three or more directions in the front-rear direction.

That is, according to the present invention, it is possible to easily adjust the number of the resonance chamber 121 disposed in the front and rear direction to make the ventilation type soundproof panel (100).

Ventilated soundproof panel 100 as described above has a resonance chamber forming member 120 to form a resonance chamber 121 and the resonance hole 122. 2 shows that the resonance chamber forming member 120 in two layers of the four layers of the resonance chamber forming member 120 is separated.

Ventilated soundproof panel 100 of this embodiment is the front of the outer frame 130 and the split support plate 140 and the resonance chamber forming member 120 for mounting and supporting the plurality of resonance chamber forming member 120 in the required position And a front plate 150 and a rear plate 160 attached to the rear surface.

In some cases, in FIGS. 1 to 3, the ventilation chamber soundproofing panel 100 according to the present invention may be installed at intervals from side to side to integrally form the resonance chamber forming member 120 vertically without the supporting plate 140. Can be configured. In this case, one resonance chamber is formed in a cylinder up and down.

The resonance chamber 121 disposed in the front side of the divider plate 123 and the resonance chamber 121 disposed in the rear side have a shape in which a plurality of resonance chambers 121 are arranged in two rows. The partition plate part 123 may form a groove in a portion to which the resonance chamber forming member 120 is coupled to facilitate assembly of the resonance chamber forming member 120, and may not move after assembly.

The resonance chamber forming member 120 may be disposed at both edges of the resonance chamber forming member 120 and may have a different shape and structure. In this embodiment, the resonance chamber forming member 120 disposed at both edges has two resonance chambers 121 disposed forward and backward, while the resonance chamber forming member 120 disposed at the center is disposed forward. A total of four resonance chambers 121 are provided with two and two arranged rearward. In some cases, the resonance chamber 121 may be formed in three or more times back and forth, and when the resonance chamber 121 is made small, it may be arranged in five or more times.

In some cases, the resonance chamber forming member 120 illustrated in FIG. 2 may be arranged in front and rear, so that the four resonance chambers 121 may be arranged before and after, so as to constitute a ventilation soundproof panel according to the present invention.

In the ventilated soundproof panel 100 as described above, the bent wind passage 110 is able to exhibit a high sound insulation performance even for noise in the middle and high frequency band of more than 1000 Hz of the noise generated from the road or railway.

Not only the noise in the mid- and low frequency bands below 500 Hz, but also the noise in the frequency band below 500 Hz to 1000 Hz is significantly improved.

The sound waves of the noise generated from the road or the railway are less amplitude from the low frequency band to the high frequency band, so that the straightness increases. It also provides excellent sound insulation performance for the noise of the band.

In addition, if the wind passage 110 is curved, the sound waves of the noise generated from the road or the rail do not pass directly through the curved wind passage 110 but hit the wall of the wind passage 110 and reflected some toward the road. While returning and some of the reflection through the wall of the wind passage 110 several times through the resonance hole 122 enters into the resonance chamber 121 and extinguishes, and some exit back.

If the wind path 110 is curved, the rate of inflow into the resonance chamber 121 through the resonance hole 122 also increases during the reflection of the sound waves several times, so that the sound insulation of the ventilation soundproof panel 100 according to the present invention is increased. Increase the effect.

On the other hand, the resonance chamber forming member 120 as shown in Figure 2 has the same cross-sectional shape is continuous, it is possible to mass production by the extrusion method.

In particular, the two resonance chamber forming members 120 disposed at both edges have the same cross-sectional shape, and thus may be made of the same extrusion mold. A fiber material may be attached to the surface of the resonance chamber forming member 120 as described above.

In some cases, the resonance chamber forming member 120 may be made of a skeleton and a fiber material surrounding the skeleton. In this case, the sound absorption performance can be improved compared to the case where a metal material or a plastic is used by arrange | positioning a fiber material in the part which a sound wave hits.

As shown, in the present invention, at least one side of the resonant chamber 121 side of the wind passage 110 for the formation of the bent wind passage 110 is formed to be bent with a resonance hole 122. When the two resonance chamber forming members 120 are arranged at intervals, the curved wind path 110 may be formed.

The wind path 110 as described above, the smaller the volume contained in the straight path disposed in a straight line from the front to the rear, the sound insulation performance is improved but adversely affects the wind load can be made by adjusting the appropriate considering both. . The wind path 110 preferably adjusts the volume included in the straight path disposed in a straight line from the front to the rear at less than half of the total volume of the wind path 110. If the sound insulation performance is more important than the wind load reduction, it is possible to prevent the straight path disposed in a straight line from the front to the rear including the direction inclined to the soundproof panel 100 as well as the direction perpendicular to the soundproof panel 100.

The outer frame 130 is formed to surround the outer edge of the resonance chamber forming member 120 as described above. The outer frame 130 is provided with a divided support plate 140 at intervals up and down. The divided support plate 140 divides the inner space of the outer frame 130 into a plurality of up and down to form a separate mounting space of the resonance chamber forming member 120 described above, and each of the resonance chamber forming members 120 mounted thereon. ) Supports to maintain the position.
