DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof wall mainly installed along a highway or a railway to cut off or absorb noise caused by a running of a vehicle or the like.

[0002]

2. Description of the Related Art In order to isolate and absorb noise caused by the running of a vehicle or the like, a soundproof panel comprising a soundproof panel in which a sound absorbing material is provided inside a hollow formed by a front plate and a rear plate having a large number of openings. Walls are erected on the side edges of highways.
In addition, on a highway, various facilities and devices such as a gaze guidance light and a road lighting using electric power are installed.

[0003]

However, if the height of the soundproof wall is low, an effective soundproofing effect cannot be expected due to the diffracted sound diffracting at the upper end.
Although it is necessary to increase the height, there is a limit in increasing the height due to economic and structural restrictions. In addition, since the gaze guide light and the road lighting are connected to a commercial power supply and supplied with electric power, the work is troublesome, the construction cost is high, and the power cost is high, which is inconvenient. Met.

Accordingly, the present invention solves the above-mentioned problems,
It is an object of the present invention to provide a soundproof wall capable of effectively reducing diffracted sound and supplying electric power to various facilities and devices such as a gaze guide light and a road lighting light.

[0005]

In order to achieve the above object, the present invention has the following arrangement. That is, the soundproofing wall according to the present invention is a soundproofing panel in which a sound absorbing material is installed in a hollow formed by a front plate and a rear plate having a large number of apertures between columns erected on a side edge of a road. It is a soundproof wall that is supported, and a shelter is provided along the longitudinal direction above the soundproof panel, and the side of the shelter bulges from the front plate of the soundproof panel, and on a slope formed at the top. A solar cell panel is attached.

According to the present invention, the side portion of the hessian provided along the longitudinal direction above the soundproof panel is bulged from the front plate on the sound source side of the soundproof panel. Diffractive sound is reduced, and the same effect as when the height is increased can be obtained. In addition, if the power generated by the solar cell panel attached to the upper part of the coping is supplied to various facilities and devices such as a gaze guidance light and a road illumination light, it is not necessary to perform a complicated construction of a commercial power supply.

Further, the solar cell panel is mounted on an inclined surface formed on an upper part of the skirting and irradiates sunlight efficiently, so that the power generation efficiency is good, and it is effective even when rain or snow is shaken on the solar cell panel. It does not fall downward, and does not hinder the power generation of the solar panel.

In the present invention, if an exterior plate is provided on the back side of the soundproof panel so as to protrude in a saw-tooth shape, and a solar cell panel is also attached to the inclined surface of the exterior plate, the solar cell panel further generates electric power. Can be increased. In addition, the solar panel mounted on the inclined surface of the outer panel, like the solar panel on the kasagi, efficiently irradiates sunlight, so that the power generation efficiency is good, and the solar panel is protected from rain and snow. Even if it shakes up, it falls down effectively and does not hinder the power generation of the solar cell panel.

[0009]

Next, an embodiment of the present invention will be specifically described with reference to FIG. That is, FIG. 1 is a perspective view showing an embodiment of a soundproof panel according to the present invention, and FIG. 2 is a sectional view thereof.

In the drawings, reference numeral 1 denotes a pillar made of H-shaped steel standing upright along a side edge of a road, and reference numeral 2 denotes a soundproof panel whose end is inserted and supported between concave grooves of the pillar 1.

The soundproof panel 2 has a sound absorbing material 24 such as glass wool inside a hollow formed by a front plate 22 having a large number of openings 21 and a rear plate 23 provided behind the front plate 22. The noise that has entered the hollow through the opening 21 of the face plate 22 is a normal noise that is absorbed by the sound absorbing material 24 and is also shielded by the back plate 23 so that the sound does not leak to the back side.

Numeral 3 is a cap attached to the upper end side surface of the support column 1 with bolts 31 and the like and provided along the longitudinal direction above the soundproof panel 2. The cap 32 has a side 32 on the sound source side. The soundproof panel 2 is swelled from the front plate 22 and has an inclined surface 33 formed on the upper part. The solar cell panel 4 is attached to the inclined surface 33.

The cap 3 may be a simple hollow one having no sound absorbing property or a solid one. However, if the cap 3 is also provided with a sound absorbing property, it is possible to reduce the diffraction sound. And sound absorption can be achieved. To provide sound absorption,
The cap 3 itself may be made of a sound-absorbing material, or may be formed from a hollow body having a large number of holes formed in the peripheral wall so that the sound incident from the holes is attenuated in the hollow. The sound absorbing material may be provided inside the hollow body, and the sound incident from the opening may be absorbed by the sound absorbing material in the hollow body, or may be another type.

The reason why the side portion 32 of the cover 3 is protruded from the front plate 22 of the soundproof panel 2 on the sound source side is to reduce the diffracted sound by the protruded side portion 32. It is preferable that the degree of protrusion be as large as possible. In addition, the inclination angle of the inclined surface 33 to which the solar cell panel 4 is attached is appropriately determined in consideration of the latitude at which the solar cell panel 4 is installed in summer and winter so that the sunlight is efficiently irradiated. In addition, if the cross-sectional shape of the cap 3 has the bulging side portion 32 and the inclined surface 33 on the upper surface as described above,
There is no particular limitation.

Reference numeral 5 denotes an exterior plate, which is attached to the side surface of the column 1 with bolts 51 and the like, and is provided so as to protrude in a sawtooth shape so as to form an inclined surface 52 on the back side of the soundproof panel 2. Further, the solar cell panel 4 is attached to the inclined surface 52. The inclination angle of the inclined surface 52 to which the solar cell panel 4 is attached is the same as that of the inclined surface 33 of the coping 3, and the latitude and the like at which the solar cell panel 4 is installed so that sunlight can be efficiently irradiated in summer and winter. It is decided in consideration of.

The cap 3 and the exterior panel 5 may be directly attached to the soundproof panel 2 and may be integrated with the soundproof panel 2, but in this embodiment, both are directly attached to the soundproof panel 2. Instead, it is attached to the column 1.
If the cap 3 and the exterior panel 5 are attached to the column 1 as described above, the cap 3 and the exterior panel 5 can be retrofitted even with the existing soundproof panel 2, and can be easily removed and replaced. Maintenance can be performed.

[0017]

According to the present invention, the side portion of the hessian provided along the longitudinal direction above the soundproof panel is bulged from the front plate which is the sound source side of the soundproof panel. The diffraction sound is reduced by the portion, and the same effect as when the height is increased can be obtained. In addition, if the power generated by the solar cell panel attached to the upper part of the coping is supplied to various facilities and devices such as a gaze guidance light and a road illumination light, it is not necessary to perform a complicated construction of a commercial power supply.

Further, the solar cell panel is mounted on an inclined surface formed on an upper portion of the coping and irradiates the solar light efficiently, so that the power generation efficiency is good, and it is effective even if rain or snow is shaken on the solar cell panel. It does not fall downward, and does not hinder the power generation of the solar panel.
