Note that FIG. 1C is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 1A, the radio wave transmission type soundproof panel of the present invention includes a metal frame body 1 formed in a window frame shape by a galvanized steel plate, an extruded material of aluminum or the like. And FIG.
As shown in (c), a resin back plate 2, a resin middle plate 3, and a resin front plate 4 are provided in the frame of the metal frame body 1. Since these are made of resin, radio waves are transmitted. can do. A sound absorbing opening 5 is formed in the resin front plate 4. The shape of the sound absorbing opening 5 is not particularly limited, and may be formed as a slit by making the resin front plate 4 into a louver shape as shown in FIG. 1C, for example. When the resin front plate 4 has a louver shape, the louver-shaped aggregate is referred to as a resin front plate 4. Further, in the radio wave transmission type soundproof panel of the present invention, as shown in FIG. 1C, an air layer 7 is provided between the resin back plate 2 and the resin intermediate plate 3, and the resin intermediate plate 3 and the resin intermediate plate 3 are provided. A sound absorbing material 6 such as rock wool or glass wool is arranged between the front plates 4, and the air layer 7 and the sound absorbing material 6 work to achieve a soundproof function. As the sound absorbing material 6, rock wool, glass wool or the like covered with a film of fluororesin or the like may be used. In the present invention, it is desirable to use a resin plate made of a polycarbonate resin as the resin back plate 2, the resin middle plate 3 and the resin front plate 4. Because the polycarbonate resin plate is strong against impact, it can also serve as a fence to prevent scattering of scattered objects from the running car outside the highway, and because it is self-extinguishing, it causes a car accident, etc. This is because there is an advantage that there is a low risk of burning in the event of fire. By coating the surface of the radio wave transmission type soundproof panel of the present invention with an acrylic paint, an inorganic paint, a paint having a property of absorbing or reflecting ultraviolet rays, it is possible to provide excellent weather resistance.

(A) is a case where a conventional metal box type soundproof panel is used as the road side wall 15, and the front side of the road side walls 15 and 15 is reflected when viewed from the radio wave transmission source 11 such as a television broadcasting station. A shielding obstacle area 13 occurs on the side where the obstacle area 12 crosses the road side walls 15, 15. In the reflection obstruction area 12 and the shielding obstruction area 13 as described above, it is necessary to take countermeasures against radio wave obstruction that requires enormous cost such as installation of a common antenna. On the other hand, FIG. 2B shows a case where the soundproof panel according to the present invention is used as the road side walls 15 and 15. Since the soundproof panel according to the present invention transmits radio waves, the reflective obstacle area 12 and the shielding obstacle area 13 are The range becomes smaller. The area shown by the broken line pattern in FIG. 2 (b) shows the obstacle reduction area 14 in which the radio disturbance is reduced by using the soundproof panel according to the present invention.
