Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting cassette, and more particularly to an improvement of a technique for greening a wall of a building or artificial ground.

[0002] In the following description, "up, down, left, right" refers to a state in which a planting cassette is mounted on a greening wall, and "front, rear" also refers to a surface facing a greening wall in that state. The side that does it is called "after" and the other side is called "before."

[0003]

2. Description of the Related Art In recent years, from the viewpoint of landscape beautification and psychological effects, greening of a wall surface of a building such as a building or an artificial ground beside a road has been frequently performed. And so on.

Conventionally, ivy plants are generally used for such greening of the wall, and they are broadly classified into climbing greening by which ivy plants can be crawled up from a planter or the like installed on the ground around the building, and a building. There are two methods: drooping greenery, which allows ivy plants to crawl down from planters installed on the roof.

[0005]

However, since all of the revegetation methods basically rely on the growth of ivy plants, it takes a considerable amount of time to cover all the target walls. Generally, wall wall greening is often required to be completed with a time limit, for example, to hold an event or open a new road. In particular, in the case of a high-rise building such as a building, the wall surface is wide, and it is difficult to make the construction by the fixed deadline.

For example, in the case of a greening wall at an event venue, it is required that the wall be restored to its original shape immediately after the event, and it is necessary to remove ivy plants to remove the wall. There is a problem that ivy plants cannot be reused.

[0007] Also, since it depends on the phenomenon of crawling up and down with growth, only ivy plants can be used. That is, there is dissatisfaction that it is not possible to give diversity to wall greening.

[0008] Further, since the growth of plants fluctuates, especially when the construction period is limited, it may not be possible to uniformly cover the greening wall surface. As a result, spots are formed on the greening wall, and the aesthetic effect is impaired.

[0009] Even if there is little fluctuation in plant growth,
Since plants generally have the property of escaping from heat, they grow by avoiding the portion of the green wall that absorbs a large amount of solar heat, and this may cause spots on the green wall.

[0010] In addition to heat, for example, if there is a tiled portion in the greening wall, ivy plants do not crawl on that portion of the wall, so that it is inevitable that spots are generated. In addition, greening itself is impossible on a wall that is entirely tiled.

Finally, in the case of high-rise buildings, there is a problem of water supply. In the case of drooping greening, in the case of climbing greening, even if water is supplied to the planters on the ground, it may not reach the high parts of ivy plants smoothly. As a result, the upper part of the ivy plant withers due to water drainage, which is against the purpose of wall greening.

In view of the current state of the prior art, the basic objects of the present invention are to quickly perform wall greening, to provide uniform wall greening, and to diversify and equalize wall greening.

Another object of the present invention is to recycle green plants, simplify water supply, and improve the degree of freedom in wall greening.

[0014]

Therefore, in the present invention, a box-shaped main body composed of front, rear, left and right side walls and a rear wall is used, and is extended at a predetermined distance from the rear wall in parallel with the rear wall. A closed space for accommodating planting soil is defined on the rear wall side by a breathable layer body, a plurality of plant insertion holes are formed in the layer body, and water passage holes are respectively formed on upper and lower side walls. At least one
The gist of the present invention is that the rear wall has an outer surface provided with a fixture for the greening wall.

[0015]

The soil is filled in the enclosed space defined by the air-permeable layer, and the roots of the plant are planted in the soil through the through holes. In this state, a plurality of planting cassettes are mounted on the target greening wall surface, preferably in a matrix, and are constructed. After that, the upper and lower planting cassettes are connected by water pipes, and water is supplied to the uppermost planting cassette. Due to the action of gravity, the water flows down to the lower planting cassette one after another and water is naturally supplied, and the plants grow and cover the greening wall. Attachment and removal can be performed freely for each planting cassette.

[0016]

FIG. 1 shows a preferred embodiment of the planting cassette of the present invention. The planting cassette 10 has a box-shaped main body 1, which is constituted by an upper side wall 11, a lower side wall 13, left and right side walls 15, and a rear wall 12, and the front surface is open. . The main body does not necessarily have to be box-shaped, but it is practical to combine a plurality of rows in a matrix when wall surface greening is performed, as described below.

At a predetermined distance from the rear wall 12 in the main body 1, a breathable layer 2 is extended substantially parallel to the rear wall 12. The layer 2 defines a closed space 14 for containing soil on the rear wall 12 side. The size of the space 14 (that is, the distance from the rear wall 12 of the layered body 2) is appropriately selected according to the plant to be planted.

Since the roots of the plants are embedded in the closed space 14, any material having air permeability may be used for the layer 2 but a non-woven fabric is usually used. However, a net-like layered material usually called an ivy net may be used instead of the nonwoven fabric.

The layer 2 has a plurality of through holes 21 for plant insertion.
Are formed, and the roots of the plant are embedded in the soil of the closed space 14 through the through holes 21. A layered pressing member 3 for suppressing this during use is provided outside the layer body 2, and is fixed to the side walls 11 to 15 at four edges. Usually, a net or the like is used for the holding member in consideration of air permeability. However, when the layer body 2 itself is stretched and fixed to the main body 1, such a pressing member need not be used.

At least one water passage hole 17 is formed in each of the upper wall 11 and the lower wall 13 so as to open to the closed space 14. Normally, it is desirable that the upper and lower through holes 17 are coaxially located for the sake of water supply described later.

It is desirable to form a plurality of through holes 19 in the rear wall 12 for the purpose of weight reduction. In this case, the through hole 1
In order to prevent the soil in the space 14 from leaking through 9, a layer 5 similar to the layer 2 is additionally provided on the inner surface of the rear wall 12.

At an appropriate position on the outer surface of the rear wall 12, at least one fixture 4 for attaching the planting cassette to the greening wall is provided. For mounting, for example, mounting fixture 4
And screwed into the greening wall side with bolts, and fastened with nuts. Alternatively, a bolt protruding from the greening wall surface side may be passed through a through hole of the fixture and fastened with a nut.

There are various methods for attaching to the greening wall. To prevent the greening wall itself from being damaged, the support 20 is appropriately attached to the greening wall as shown in FIG. It is desirable to mount the planting cassette 10 of the present invention. The arrangement of the plants 10 can be variously designed as required, but is arranged in a matrix in the illustrated example.

That is, the plurality of planting cassettes 10 are fixed to the column 20 adjacent to each other vertically and horizontally, and the through holes 17 of the upper and lower planting cassettes 10 are connected by the water pipe 30.

Although planting plants are not shown in FIG. 2, the space 14 is filled with soil prior to construction, and plant roots are planted in the soil through the through holes 21 for insertion. However, planting may be done after construction.

After the installation, the water pipe 30 of the uppermost planting cassette 10 is connected to a water supply source such as a water tap by an appropriate hose or the like. The supplied water first flows into the soil in the uppermost planting cassette 10, and when it is saturated, it flows into the soil in the next lower planting cassette 10 by the action of gravity.

[0027]

According to the present invention, since the plant does not depend on the growth of the greening wall, the greening of the wall can be achieved quickly within the required period.
For the same reason, the plants to be planted are not limited to ivy plants, so it is possible to perform a wide variety of wall greening. Furthermore, for the same reason, the green wall surface can be uniformly covered with planting plants without being affected by solar heat or wall material.

When the greening of the wall is no longer necessary, the entire planting cassette is removed from the wall, and the plant itself does not need to be cut off. Therefore, the plant can be reused any number of times as long as it is alive. it can. In addition, since the plants used are not limited to ivy plants, the degree of freedom in greening the wall surface is greatly improved. Further, since the water is lowered by gravity, water can be easily supplied and there is no fear of running out of water.
