As shown in FIG. 2, the road soundproofing wall 10 of the present invention has a sheet of soundproofing plates 103 installed between struts 102 which are erected at regular intervals on the foundation concrete 101, and at least between the soundproofing plates 103. One or more rotary ventilation members 20 are interposed.

The rotary ventilation member 20 is the inside of the wind from the inside to the outside or the outside when the wind pressure acts on the inside (I) (road side) or the outside (O) (building side) of the soundproof wall 10 as shown in FIG. It is configured to be rotated by the wind pressure to ventilate by so as to relieve the wind load of the soundproof wall (10).

The rotary ventilation member 20, the first and second frames are interposed between the soundproof plate 103 interposed between the struts 102 as shown in Figures 2 and 3 to form an appearance and connected in a row (21) (22) and the shaft (24) rotatably installed through both sides in the first and second frames (21) (22), and the outer diameter of the shaft (24), A plurality of wind vanes 26 for rotating the shaft 24 and upper and lower portions of the first and second frames 21 and 22, respectively, and circular arcs when the wind vanes 26 rotate. It is composed of a noise blocking wing 28 positioned close to the end 26a of the wind wing 26 along the arc to block the noise.

The first and second frames 21 and 22 may be formed by forming one side in the form of unevenness 21a and 22a as shown in FIG. 3 and connecting them to each other by fixing means such as bolts (not shown). In addition, as shown in FIG. 4, the connecting pieces 21b and 22b may be formed on one side of the first and second frames 21 and 22 and connected to each other by fixing means such as bolts 23. As shown in FIG. 5, the first and second frames 21 and 22 are formed in a single body, and the reinforcement frame 25 is vertically installed in the middle of the first and second frames 21 and 22 so that two wind vanes are provided. (26) can be manufactured so that a partition can be installed.

In the above, the shaft 24 having the wind vanes 26 is installed to be rotatable through the shaft holes 21c and 22c formed on both sides of the first and second frames 21 and 22, and as necessary. By installing a bearing (not shown), the rotation of the shaft 24 may be smoothed and rotational noise may be prevented. When using bearings, oil-free bearings may be used in consideration of the installation condition of the sound barrier.

As shown in Figure 6 it is important that the arc length (L) of the noise shield 28 is made of a length at which at least two wind wings 26 are located.

That is, as shown in FIG. 6, when the wind vanes 26 rotate, the length L at which at least two wind vanes 26 are located among the wind vanes 26 made up of a plurality of noise shielding vanes 28 is located. By being formed with the noise contained in the wind ventilated through the wind wing 26 is cut off from the noise blocking wing 28, the wind is finally ventilated and the noise is blocked.

If there is no noise shield 28, or if the length is long enough to block one wind wing 26, the wind vane 26 is used to make noise with the wind through the noise shield 28. This will leak out.

On the other hand, the wind wing 26 is preferably in the cross section to induce a rotation in one direction as shown in Figure 6 and at the same time well receive the wind.

Accordingly, when the wind blows from the inner side (I) or the outer side (O) of the soundproof wall 10 and the wind pressure is generated in the soundproof wall 10, the wind vanes 26 rotate in one direction and the outer side (O) from the inner side (I). Ventilation is done either inward or outward (O) to inward (I).

In the above wind blade 26 can be formed integrally with the outer diameter of the shaft 24, in consideration of manufacturability can be used to detachably assembled from the shaft 24.

And the wind wing 26 is formed by a transparent body can be seen from the inside (I) and the outside (O) by the wind wing 26 to improve the aesthetics of the soundproof wall 10, with the above By having the wind vanes 26 have a volume, the aesthetics of the soundproof wall 10 can be improved.

Meanwhile, a sound absorbing material 30 may be attached to the surface of the noise blocking wing 28 as illustrated in FIG. 7A, and similarly, a sound absorbing material 32 may be attached to the surface of the wind wing 26. Can be.

As described above, by forming the suction members 30 and 32 on the noise blocking wings 28 and the wind wings 26, noise can be effectively blocked.

On the other hand, in the case of the noise blocking wing 28 is less affected by wind will be able to form a sound-absorbing material of the noise blocking blade 28 as a sound absorbing material.

In the case of the wind wing 26, the wind wing 26 itself may be made of a material having sound absorption, but in the case of the sound absorbing material, it is usually made of porous, so the bending rigidity is weak and should be considered.

Meanwhile, as illustrated in FIG. 7B, a plurality of dimples 26b having a concave shape may be formed on the surface of the wind wing 26, and as shown in FIG. 7C, the surface of the wind wing 26 may be convex. It can be configured by forming a plurality of projections (26c).

As described above, since a plurality of dimples 26b or protrusions 26c are formed on the surface of the wind blades 26, noise introduced into the wind wings 26 is diffusely reflected by the dimples 26b or the protrusions 26c. In the process, the noise is reduced and the sound absorption area is increased.

In addition, since a plurality of dimples 26b or protrusions 26c are formed on the surface of the wind vane 26, the surface area of the wind vane 26 is increased to increase the air volume and wind pressure. Accordingly, under the same conditions, the size of the wind wing 26 can be reduced by the increased surface area due to the dimple 26b or the protrusion 26c, thereby contributing to the miniaturization of the wind wing 26.

8 and 9 show another modified example of the rotary ventilation member 20a of the present invention, the rotary ventilation member 20a is interposed between the soundproof plates 103 to form an appearance, and reinforcing frame 29 in the middle. ) Is formed on the frame 27 and the shaft 24 and the outer diameter of the shaft 24 are rotatably installed through the upper and lower sides in the frame 27 partitioned by the reinforcement frame 29, respectively. And a plurality of wind vanes 26 and the upper and lower portions of the frame 27 and the reinforcing frame 29 to rotate the shaft 24 by wind pressure, respectively, and the wind vanes 26 are formed. It is composed of a noise blocking wing 28 is positioned close to the end (26a) of the wind wing (26) along the circular arc to block the noise.

In the case of the rotary ventilation member 20 shown in Figs. 2 to 6, the wind vanes 26 are installed in a row between the sound insulation plates 103, and the rotation shown in Figs. The ventilation member 20a is provided with a plurality of wind vanes 26 in a row between the sound insulation plates 103.

In the above, but illustrated in a row or in a row by two units for the rotary ventilation member 20, 20a provided between the soundproof plate 20, but is not limited to this, the length between the struts 102 or the height of the soundproof plate Therefore, two or more units can be installed in succession.

As described above, the two frames 21 and 22 are separated and coupled or the frame 27 is installed so that one or more rotary ventilation members 20 and 20a may be installed in a row or column between the sound insulation plates 103. By allowing the plurality of wind vanes 26 to be installed as a single body by the reinforcing frame 29, the length between the strut 102 and the strut 102 can be positively corresponded between the strut 102 and the strut 102. The rigidity of the deformation of the rotary ventilation member 20, 20a generated when the length is long increases the rigidity of the frames 21, 22, 27, and the wind vanes 26 including the shaft 24 are not deformed and stable. The rotation will be corrected.

It can be formed of a metal or synthetic resin for the entire component of the rotary ventilation member 20, 20a configured as described above, in particular in the case of the wind blade 26 including the shaft 24 is formed of a rigid synthetic resin Preferably, the noise blocking wings 28 may be installed on the frames 21, 22, 27 after being integrally or separately manufactured to the frames 21, 22, 27.

According to the present invention configured as described above, at least one or more rotary ventilation members 20 and 20a are interposed between the soundproof plates 103 to constitute the soundproof wall 10. When the wind blade 26 is rotated in one direction to actuate the soundproof wall 10 when acting on the road side) or the outer side (O) (building side), the soundproof wall 10 is protected from wind load, and the noise shielding wing 28 is provided. Is always formed in close proximity to the end (26a) of the two wind wings (26), when the wind wing 26 is rotated by the noise blocking blade (28) in close proximity to the wind wing (26) Wind vane (26) will not pass through to block the noise.

As described above, the rotary ventilation members 20 and 20a interposed between the sound insulation plates 103 are constructed in consideration of the height and length of the soundproof wall 10 and the installation strength of the soundproof wall 10. One or more than one can be provided between the sound insulation boards 103 for every line between them.

In recent years, typhoons and gusts are frequently generated due to climate change caused by rapid environmental changes in the world. It helps to prevent damage of soundproof wall from typhoon and gust by securing stability.

In addition, the present invention contributes to noise isolating by the noise-blocking wing that is located close to this even when the wind blade of the rotary ventilation member continues to rotate.

In addition, the present invention contributes to improving the aesthetics of the soundproof wall by the volume of the rotary ventilation member interposed between the soundproof plates.

In addition, the present invention, by providing one or more rotational ventilation member in a horizontal or vertical line between the soundproof plate to increase the deformation rigidity of the rotary ventilation member to ensure stable rotation because the wind wing including the shaft is not deformed with the rigidity of the frame.
