Description

  The present invention mainly relates to a soundproof wall installed along a highway, a railway line, and the like in order to insulate and absorb noise associated with traveling of a vehicle or the like.

  A soundproof wall consisting of a soundproofing panel with a sound-absorbing material inside a hollow formed by a front plate and a rear plate with a large number of apertures in order to insulate and absorb the noise associated with traveling of the vehicle etc. It is erected on the side edge. Various things are disclosed about the invention which attaches a solar cell to this and gives a sound-proof wall a power generation function.

  For example, Patent Document 1 discloses a solar cell for a sound insulation wall in which a sheet-like amorphous silicon solar cell module is attached to a back surface of a concrete block sound insulation wall made of concrete such as an expressway using a mounting bracket.

JP 2006-270006 A

  However, since the solar cell for the sound insulation wall as in Patent Document 1 is mounted in parallel with the sound insulation panel, the installation angle of the solar cell is in accordance with the installation angle of the sound insulation wall. Therefore, when the solar cell is attached to the vertical sound insulation wall, There was a problem that the power generation efficiency was lower than the case of mounting in the solar direction. Moreover, since a solar cell is attached to the back surface of a sound insulation wall, there existed a problem that it did not contribute at all about the sound absorption effect of a sound insulation wall.

  Therefore, the present invention provides a soundproof wall having a power generation member attached with a solar cell panel inclined obliquely upward and also having a sound absorbing effect.

In order to achieve the above object, the present invention is configured as follows.
That is, the soundproof wall according to the present invention includes the first sound absorbing material in the hollow formed by the front plate having a large number of openings and the back plate between the columns provided on the side edges of the road. A soundproof panel is formed, and a plurality of inclined plates are provided on the front side of the soundproof panel so as to protrude forward, and a plurality of solar panels are attached to the surface of the inclined plate. The inclined plate and the front plate The second sound-absorbing material is housed in a space portion in which the inclined plate formed between and the oblique side is a hypotenuse and the lower portion is opened and the cross section in a side view is a right triangle.

  According to the soundproof wall according to the present invention, since the inclined plate descending forward is provided on the front side of the soundproof panel and the solar cell panel is attached to the surface of the inclined plate, the solar cell panel is inclined upwardly facing the sun. Can be installed in the direction.

  Further, since the second sound absorbing material is housed in the space formed between the inclined plate and the front plate, the member itself attached in front of the front plate of the soundproof panel can have a sound absorbing effect. As a result, most of the noise generated from the sound source in front of the soundproof panel and transmitted through the soundproof wall is first attenuated when passing through the second sound absorbing material, and further passes through the first sound absorbing material provided in the soundproof panel. In this case, since the sound is attenuated again, a higher sound absorption effect can be obtained than the soundproof wall provided with only the soundproof panel. Further, even when the sound transmitted through the second sound absorbing material is reflected by the front plate of the soundproof panel, it is attenuated again by hitting the second sound absorbing material, so that a high sound absorbing effect can be obtained. In addition, since the lower part of the space portion in which the second sound absorbing material is installed is open, the noise source of the noise from the downside due to contact between the vehicle traveling on the road and the road surface, and the second sound absorbing material installed There is no obstacle between the materials, and the noise is attenuated without being reflected, and a high sound absorption effect can be obtained. In addition, since the lower part of the space where the second sound absorbing material is installed is open, even if noise from the front of the soundproof wall hits the surface of the solar panel and is reflected upward, Since there is no object that interrupts the second sound absorbing material built in the inclined plate attached to the sound, the noise is attenuated without being reflected again and a high sound absorbing effect can be obtained. In addition, the space formed between the inclined plate and the front plate is formed so that the cross section from the side view is a right triangle with the inclined plate as the hypotenuse, so that it will rain even if the lower part of the space is opened. Even in the case of snowfall or snowfall, the rain and snow flowing on the inclined plate flow downward without contacting the second sound-absorbing material.

In addition, if the second sound absorbing material is an integral sound absorbing material having a right-angled triangular cross-section with a hypotenuse on the surface corresponding to the back surface of the inclined plate, the second sound absorbing material provided therein is connected to the inclined plate and the front. Compared with the case where there is a space between the front plate of the soundproof panel and the back surface of the inclined plate, the cross-sectional area of the second sound absorbing material is closed because the space portion of the right triangle shape formed between the face plate and the face plate is closed. This is preferable because a higher sound absorbing effect can be obtained when noise passes through the second sound absorbing material.

  The second sound absorbing material is an integral sound absorbing material in which a bottom wall portion corresponding to the lower portion of the opened inclined plate and an inclined wall portion corresponding to the back surface of the inclined plate form a substantially L-shaped cross section. Then, since the rigidity in the longitudinal direction of the second sound absorbing material is enhanced by the corner portion of the L shape, the sound absorbing material in which the wall portion corresponding to the lower portion of the inclined plate and the wall portion corresponding to the back surface of the inclined plate are separated. As compared with the material, the second sound absorbing material is preferably prevented from being damaged by an external force. In addition, compared to a sound absorbing material in which the wall portion corresponding to the lower portion of the inclined plate and the wall portion corresponding to the back surface of the inclined plate are separated, noise or the like leaks from the gaps between the individual sound absorbing materials. This is preferable because a high sound absorption effect can be obtained.

  According to the soundproof wall according to the present invention, the solar cell panel can be installed obliquely upward, and a high sound absorption effect can be obtained.
