DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a green soundproofing wall in which plants can be vegetated.

[0002]

2. Description of the Related Art Conventionally, soundproof walls are provided in places where noise is severe such as roads. However, since these soundproof walls are made of metal, ceramic, synthetic resin, and other plate members continuously provided on the surface, the overall structure of the soundproof walls is uniform and has little change. . In addition, since no soil exists on the elevated road, it was not possible to vegetate plants or to make the soundproof walls green. Therefore, if the monotonous soundproof wall continues along the road for a long distance, the landscape of the road space is killed and the change is scarce, so the psychological effect such as mental tension and oppression feeling on the driver is large, There is a problem that the body and mind are easily fatigued.

As a method for solving such a problem, as described in Japanese Utility Model Publication No. Sho 63-22162, a greening soundproof wall is known in which a soil container for vegetation is provided on the soundproof side of the soundproof wall. I have. Also, 63-19555
As described in JP-A No. 1 (1993) -197, a soundproof panel having a fiber sound absorbing material such as glass wool therein, wherein a nutrient solution is put into the fiber sound absorbing material such as glass wool in the sound insulating panel, There is also known a greening soundproofing wall in which a plant planting port is provided on the back material and plants are planted in the plant planting port.

[0004]

The above-mentioned green soundproofing wall is preferable because the soundproofing side of the soundproofing wall is covered with vegetation and turns green, so that it is easy on the eyes and reduces driver fatigue, which is preferable. There is a problem that the soundproofing effect is inferior to the case where it is not provided. As a result of the present inventor's research on the cause, it was found that the soil accommodating portion provided on the soundproof surface side would block the soundproof surface, impairing the soundproof effect.

Further, in the soundproof wall described in the latter publication, a nutrient solution is put in glass wool. However, when a liquid is put in glass wool, the soundproofing effect is significantly reduced. is there. Then, an object of the present invention is to provide a greening soundproof wall which can be installed on an elevated road where there is no soil and does not impair the soundproofing effect.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and has been made under the above and below the soundproof wall.
A soil storage part for vegetation of the plant is provided in one or the middle part , and a sound absorbing panel is provided on the soundproof surface side of the soil storage so as to provide a gap where the plant grows and cover the soil storage. Is what it is. Further, it has been made so that both the soil volume portion yield only or soil <br/> yield capacity unit and sound absorbing panels are integrated assembly and unitized with sound barrier.

For example, a wall of a metal plate, a ceramic plate, a synthetic resin plate, etc. on the soundproof side is provided with a large number of slits or punched through holes, and natural fibers, synthetic fibers, glass wool, rock wool, etc. are provided in the wall. A sound absorbing material may be inserted, or only a sound absorbing material such as a porous ceramic body may be used.

[0008] The sound-absorbing panel used in the present invention is provided on the soundproof surface side of the soil storage portion so as to cover the soil storage portion while maintaining a gap where plants grow. The width of this gap may be arbitrary, but is preferably 5 to 20 cm. or,
The sound absorbing panel has a sound absorbing material, and this sound absorbing material may be the same as the sound absorbing material used for the sound insulating wall, or may be a different sound absorbing material.

The method of providing this sound absorbing panel on a soundproof wall is as follows.
What is necessary is just to surround a sound-absorbing material with a board material suitably and attach it to a soundproof wall.
The sound absorbing panel may be integrated with the soundproof wall in advance,
The soundproof wall may be divided and unitized to be attached to the soundproof wall. The structure of the sound-absorbing panel is similar to that of the sound-insulating wall. The sound-absorbing material is provided with holes in the plate provided on the sound-insulating surface side so that the sound-insulating effect is not impaired. Holes are provided so as not to impair the soundproofing effect.

In the present invention, above, below, or
A soil storage unit is provided in the middle. As the soil container, a conventionally known one can be used. For example, a container formed of a material such as metal, ceramic, or synthetic resin in a shape that can accommodate soil may be attached to the upper, lower, or intermediate portion of the soundproof wall, or a part of the soundproof wall may be capable of housing soil. Any shape may be used. Also, if the soil storage part is divided into soundproof walls and unitized, it is built into the soundproof wall. After planting the plant in the soil storage part, it can be built into the soundproof wall, and assembling workability can be improved. Along with good
The replacement of the soil storage unit or the plant is also easy, which is preferable.

The location of the soil storage portion provided on the soundproof wall depends on the type of plant to be vegetated . For example, if the plant has a property of hanging downward, the soil storage portion is provided above the soundproof wall. What is necessary is just to provide it below the soundproof wall if it is a plant body having the property of extending upward.

[0012] As the plant, vine plants such as honeysuckle, hedera, periwinkle, giant locust, periwinkle, periwinkle, chinensis, akebi and ivy are preferably used. Further, it is preferable to provide a drainage port in this soil containing section for discharging excess water, similarly to the flowerpot.

[0013]

The greening soundproof wall of the present invention may be located above, below, or above the soundproof wall.
Since the soil storage part for vegetating the plant is provided in the middle part , the soil can be stored in the soil storage part and the plant can be vegetated. When plants are vegetated in this way, the greening soundproofing walls are provided with the gaps where the plants grow, so the plants grow out of the soil storage portion and cover the soundproofing walls. The green color of this plant is easy on the eyes of the driver passing through the road, so that driver fatigue is reduced.

Further, since the sound absorbing panel is provided so as to cover the soil containing portion, even if the sound absorbing performance of the soil containing portion is inferior, the sound that is blocked by the sound absorbing panel and is absorbed and reaches the soil containing portion is reduced. In addition, the sound reflected from the soil storage portion is absorbed by the sound absorbing panel. Therefore, the soundproofing performance is not reduced by the soil storage portion.
