DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof wall which can be partially greened by appropriately combining a sound absorbing panel and a planting panel. It relates to the structure for supplying water.

[0002]

2. Description of the Related Art Various techniques relating to plant walls for soundproofing have been developed. In addition, the inventor of the present application discloses not only a sound-insulating wall of a full greening type, but also a technique regarding a sound-insulating wall that partially greens an appropriate part of a wall surface by combining a sound absorbing panel and a planting panel (for example, JP-A-8-134494, JP-A-9-9787).

[0003]

Any of the above prior arts relates to a partial greening type soundproof wall in which a sound absorbing panel is mixed in a wall. However, water supply to a planting panel is particularly different. No action was taken. That is, in the part where the planting panels are vertically continuous in the wall, water can permeate from the upper layer to the lower layer, so that no particular problem occurs, but the planting panels and the sound absorbing panels are stacked vertically. It is necessary to skip the sound-absorbing panels and supply water to the planting panels. For this reason, conventionally, a separate water pipe has been prepared, and the water pipe has been used to connect the drainage part of the upper planting panel and the water supply part of the lower planting panel while avoiding the sound absorbing panel. Was.

[0004] However, in this means, since the water pipe must be laid vertically and horizontally, the degree of freedom of the combination of the planting panel and the sound absorbing panel is lost in consideration of the trouble, and the soundproof wall is formed by combining them randomly. If constructed, there is a problem that the piping work is complicated. This problem is remarkable when a large-sized one such as a soundproof wall of a highway is to be constructed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to supply water to a planting panel without impairing the basic performance such as greening workability and sound absorption of this kind of soundproof wall. To improve the piping workability.

[0006]

In order to achieve the above-mentioned object, according to the present invention, a sound-absorbing panel having a sound-absorbing material therein and a planting panel which can be planted in the front are appropriately combined and stacked. In constructing a soundproofing wall capable of greening, the planting panel is provided with a water supply port at the top and a drainage port at the bottom, while the sound-absorbing panel is internally provided with a communication port with the above water supply port or drainage port of the planting panel. A means of providing a vertical pipe for water was used. According to the means, by simply stacking the sound absorbing panel and the planting panel,
A water supply channel to the planting panel is secured by the vertical pipe, and piping work for the water supply is omitted at all.

According to the second aspect of the present invention, when a plurality of planting panels are housed side by side in a single box, a plurality of sound absorbing panels are provided corresponding to the number of each planting box. Means of providing a water passage pipe for the book was used.

According to a third aspect of the present invention, in the sound absorbing panel, means for providing an air layer between the sound absorbing material and the back plate is used, and at least a sound absorbing function is obtained by the air layer, and the vertical pipe is formed by the heat insulating function. The temperature of the water flowing through is also prevented.

According to a fourth aspect of the present invention, a rib is formed by projecting a part of the back plate of the sound absorbing panel toward the inside of the panel in a substantially U-shaped cross section, and a sound absorbing material is arranged using the rib as a spacer. The means of forming a layer was used. Therefore, the air layer can be formed only by arranging the sound absorbing material along the rib without using a separate spacer member.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing a case where a sound absorbing panel 10 and a planting panel 20 are alternately stacked in order from the bottom to construct a partially greening type soundproof wall. Here, in stacking the panels 10 and 20, an appropriate support (not shown) such as an H-section steel may be used to prevent the panels 10 and 20 from overturning. There may be 20 stacks.

In this embodiment, as shown in FIG. 1 and FIG. 2, a sound-absorbing panel 10 has a sound-absorbing panel typified by glass wool or a foamed resin material inside a box 11 having a substantially U-shaped cross section with an open front surface. Material 12 is housed, and the box 1
Vertical pipes 14... 14 for water flow are provided between a plurality of through holes 13a and 13b formed on the upper and lower surfaces of the device 1 respectively. Here, the rib 16 and the sound absorbing material 12 are arranged on the back plate 15 of the casing 11 by projecting the rib 16 inward in the longitudinal direction thereof and arranging the sound absorbing material 12 along the rib 16.
An air space 17 is provided between the two. On the front surface of the sound absorbing panel 10 having such an internal structure, a front plate 19 on which a louver 18 with a plurality of sound holes is formed is attached.

On the other hand, as shown in FIGS. 1 and 3, the planting panel 20 has a box 21 having the same shape as the sound absorbing panel 10.
Along with the ribs 22, the same sound absorbing material 23 as used in the sound absorbing panel 10 is housed inside, and a total of seven planting boxes 24, which are partitioned into three upper and lower stages, are housed side by side. A water passage hole 24b is formed in the internal partition plate 24a of the planting box 24, and each section is filled with a planting base material 24c made of natural soil or artificial soil. Moreover, the planting panel 20 having the internal structure is
A water supply port 25 and a drain port 26 are provided on the upper and lower surfaces of the box 21 corresponding to each planting box 24, and a front plate of the planting box 24 having a planting hole 27 formed on the front surface of the box 21. 28 are arranged. In addition, the through holes 13a and 13b and the vertical pipe 14 in the sound absorbing panel 10 are also provided corresponding to each planting box 24. In the planting panel 20, an air layer 29 is formed between the rib 22 and the sound absorbing material 23.

The sound absorbing panel 10 and the planting panel 2 having the above-described configuration.
0 has the following basic performance by itself.
That is, according to the sound absorbing panel 10, the sound generated on the front surface of the panel passes through the louver 18 and is absorbed by the sound absorbing material 12,
Furthermore, the sound that could not be absorbed by the sound absorbing material 12 is
Is absorbed by. Further, since the air layer 17 also exerts a heat insulating effect, the vertical pipe 14
To prevent the water flowing through the plant from becoming hot, and protect the growth of plants in the planting panel 20. Furthermore, with the louver 18,
Since the infiltration of rainwater into the panel is prevented, the sound absorbing material 1
2 is effective when glass wool having low water resistance is used.

On the other hand, according to the planting panel 20, greening is completed by setting the planting box 24 which has been planted in advance in the box 21, or by planting the plant in the planting box 24 which has been set. I do. Further, the planting base material 24c and the sound absorbing material 23 filled in the planting box 24 exhibit a sound absorbing effect, and sound is absorbed by the air layer 29. Further, the heat insulating effect of the sound absorbing material 23 and the air layer 29 prevents burning of the planting box 24 due to radiant heat on the back side of the panel, and has little effect on plants.

Then, by simply stacking the sound absorbing panel 10 and the planting panel 20 having the above structure, as shown in FIG. 4, the upper layer is drained by the vertical pipe 14 corresponding to each planting box 24, and the lower layer is drained. Since water is supplied at the same time, piping work for water supply and drainage can be omitted altogether. At this time, the vertical pipe 14 merely sends water to the lower panel, so that the water supply to the lower layer does not decrease while passing through the sound absorbing panel 10 and each planting panel 2
Water can be uniformly supplied to zero. In FIG. 4, reference numeral 30 denotes a main water supply pipe provided at the uppermost stage of the soundproof wall;
Is a base made up of a drain 41 for drainage and a drain pipe 42.

[0016]

As described above, according to the present invention, since the sound-absorbing panel has not only the sound-absorbing means but also the water-supplying means for the planting panel, the water-supplying piping is completed simultaneously with the construction of the partially greening type soundproof wall. In addition, due to the heat insulation effect of the sound absorbing panel having an air layer on the back side, the temperature change of water supplied to the planting panel is reduced even in an urban area where the temperature difference is particularly large between day and night, and the plants die. And growth failure can be prevented.
