DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening unit and, more particularly, to a greening unit suitable for being installed on a roof having a flat roof such as a building.

[0002]

2. Description of the Related Art In recent years, especially in urban areas, from the viewpoint of improving the environment against the heat island phenomenon and air pollution,
It has been proposed that plants be cultivated on the roof of a building that has a flat roof like a building and become green.
Some have been implemented.

[0003] As a conventional greening means, for example, typically, a waterproof sheet is laid on a base surface such as a roof to be greened, and the waterproof sheet surface is made of soil or compost. There is a method in which a so-called plant cultivation soil is provided with an appropriate layer thickness, and a plant or a seed of a plant, which is appropriately grown, is planted in the cultivation soil.

[0004] As another simple means, a large number of containers made of wood, plastic material or the like having a required size are installed on a rooftop, and this container is filled with plant cultivation soil and plants and seeds are seeded. There are also things.

[0005] However, in the former, when the base surface to be constructed is wide, there are difficulties in terms of workability and maintenance properties such as waterproofing. Also, in the latter, since the unit method is used, with respect to the problems such as workability and waterproofness, a sufficient effect can be expected from the former, but the workability is improved, and it is possible to cope with various base surface shapes. In order to provide versatility, it is required to make each container relatively small in size. Further, many containers made of a material such as plastic have a plate thickness of about 1 cm or several cm due to problems such as rigidity and material.
Therefore, when a large number of these containers are juxtaposed, the plate thickness portion of the containers appears as a considerable dead space in terms of the green area even when the containers are in contact with each other. In particular, when the plant is a plant with a short height or the like, the dead space is easily noticeable as a gap,
The sense of unity (one-sided feeling) as greening is easily damaged.

Furthermore, considering the recent trend toward resource saving, there is a problem that a large amount of resources such as wood is consumed, and particularly when a plastic container is used, it is likely to become a new source of environmental pollution when the plastic container is discarded. Such,
Although it is a greening means for the purpose of improving the environment, the present situation is that the results are contradictory in a certain sense. Furthermore, in these conventional methods, it is difficult to control the water required for growing the plants, and it is particularly difficult to control the piping and the amount of water supply, and it has been difficult to germinate the seeds or to wither the plants.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is directed to a unit system using a planting container, which minimizes the dead space between adjacent planting containers and saves resources. It is an object of the present invention to provide a greening unit that is effective for planting, is easy to manage water, is suitable for growing plants, and does not easily cause environmental pollution at the time of disposal.
