Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a structure in which planting boards, each of which is a long rectangular plate bent in a dogleg shape in the longitudinal direction, are arranged in multiple stages at engaging portions provided on both side edges of studs that are erected at predetermined intervals. Fill the void surrounded by studs and planting boards with earth and sand, facing the position where steps are set at different heights to block noise transmission, and expose the area between the upper and lower planting boards. This invention relates to a vegetation sound wall characterized by planting trees on the soil surface, and is an improvement of the invention disclosed in Japanese Patent Application No. 54-38861.

The invention related to Japanese Patent Application No. 54-38861 is based on the fact that the upper and lower side plates installed on both side edges of the studs are in symmetrical positions, so the void surrounded by the studs and side plates on both sides is filled with earth and sand to form a soundproof wall. However, the earth and sand press against each other at the bottom of each side panel, and as the earth settles, a gap is created between the upper and lower side panels, and in severe cases, it is possible to see into the other side of the soundproof wall, and noise can easily pass through the gap. The soundproof wall will no longer serve its purpose.

The present invention improves on these drawbacks, and its embodiment will be described in detail with reference to the drawings.As shown in Figures 3 to 7, the lower part is buried in the soil and planted at predetermined intervals. Sawtooth-shaped locking protrusions 2, 2, etc. are continuously left over approximately the entire length of both side edges of the concrete stud 1, and the heights of the left and right sides are staggered, and a groove 3 is provided. A large number of vertically elongated rectangular through holes 4 are formed through the groove 3 at regular intervals. 8th
As shown in FIGS. 10 to 10, a long rectangular plate is bent into a dogleg shape in the longitudinal direction, and one corner of both short sides is cut into an L shape to form the locking convex portion 2.
A planting board 6 is formed by providing projecting edges 5, 5 that engage with the.

Therefore, as shown in Fig. 1, when the ground surfaces on both sides of the soundproof wall are at the same height, all the locking protrusions 2...
When the projecting edges 5, 5 of the planting boards 10 are engaged and built in multiple stages, and as shown in FIG. In this case, the planting wall 7, which is formed by thickening only the wall thickness of the planting board 6, is engaged with the locking convex portion 2 on the lower side (right side in the embodiment) where the ground surface is lower than the ground surface on the higher side in multiple stages. In this case, sawtooth-shaped locking protrusions 2 formed on both side edges of the studs 1,
The planted boards 6 erected in multiple stages in 2 are staggered in height on the left and right sides, and can form a soundproof wall having vegetation on both wall surfaces as shown in FIGS. 1 and 2. Incidentally, the exposed area of the vegetation part can be made wide by bending the plate into a dogleg shape, and since the vegetation wall 7 is formed thickly, it can sufficiently withstand earth pressure.

Since the present invention is constructed in this manner, the studs 1 are erected at regular intervals, and the planting boards 6 are erected in multiple stages across the opposing locking ridges 2, 2, and the ground surface on either the left or right is high. , the planted walls 7 are built in multiple stages below the planted boards 6, and the studs 1 and
If the empty space surrounded by the planting boards 6 and the planting walls 7 is filled with earth and sand, and the exposed part of the earth and sand formed between the upper and lower planting boards 6 or the planting walls 7 is covered with grass or other vegetation, the entire wall surface will be covered. In addition to being able to create greenery and creating an excellent landscape, the planted boards 6 built on both side edges overlap each other in the direction of noise transmission, so there is no gap for noise to pass through. Because they are built with different heights on the left and right, the lower ends of both planting boards are shifted vertically, creating a wider internal space. Since this does not occur, the soundproofing effect is great when combined with the earth and sand filled inside and the lush vegetation on the exposed parts of the earth and sand.

As described above, the present invention is an excellent and useful invention that can be easily and quickly constructed, and the constructed soundproof wall is beautiful because it is covered with greenery, and is robust and durable for long-term use.

Claims (1)

[Claims] 1. At the engaging parts provided on both side edges of the studs that are erected at predetermined intervals, the planting boards, which are long rectangular plates bent in a dogleg shape in the longitudinal direction, are stacked in multiple stages so that their heights are staggered. A vegetated soundproof wall is constructed by filling earth and sand into a void surrounded by built-in studs and planting boards facing a position that is provided to block noise transmission.
