Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening apparatus and a method for forming a rooftop greening apparatus in a building. The present invention relates to a greening and prevention structure on a roof of a building such as a house or a building, and particularly, by constructing a lawn, a farm, a flower bed or a small garden on the roof of a house or a veranda by simple and reliable means, and The present invention relates to a greening structure for cultivating various plants.

[0002]

2. Description of the Related Art Conventionally, attempts have been made to cultivate flowers and plants by making small gardens or flower beds on the roofs of various buildings. In most cases, a rooftop painting is formed using concrete or other materials to form an enclosure, soil is laid in the enclosure, plants are planted, and water and chemical fertilizers are sprayed for cultivation. 2. By cultivating grass and plants on the roof of the building in this way, it has an effect of preventing the reflection of sunlight in summer and suppressing a rise in the temperature in the building. In addition, since the pollution of the air has been progressing in large cities recently, greening the rooftops of various buildings has the effect of improving the landscape of air purification and promoting greening of many buildings. Is the current state of need.

[0003]

The above-mentioned prior art has the following problems. 1. It is an essential requirement that materials for making lawns, flower beds, small gardens, etc. on the roof of buildings such as dwellings and buildings be lightweight in order to reduce the burden on the buildings. Furthermore, on the rooftop, there is a problem that the culture soil such as the soil is easily dried due to the influence of the wind, and the surface layer is scattered by the strong wind. 2. Furthermore, the heavy use of chemical fertilizers on the roof of buildings such as dwellings and buildings has the disadvantage that concrete and other aggregates deteriorate. In addition, it is required that water be stored in the flowerbed during rainfall and excess rainwater be drained smoothly. If soil or the like is mixed in the drainage, there is a problem that a drain pipe leading to the ground may be clogged. 3. Furthermore, in large cities with high land prices, it is difficult to create a garden of sufficient size, and there is little opportunity to get close to green and get the joy of growing plants and growing crops. for that reason,
Even if you do not have a garden, you can use the rooftop or veranda to construct lawns, flower beds, small gardens, and so forth, and if you can grow fresh flowers and trees and grow vegetables, you will be able to refresh and reduce stress.

[0004] The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. The present invention adopts lightweight materials to reduce the roof load on the building, and keeps the water in the water tank during rainfall without scattering and drying of the soil due to the wind, and the excess water is smoothly passed through the drain pipe. It is an object of the present invention to provide a rooftop greening structure of a building such as a house or a building capable of draining water. A.

Since the present invention is configured as described above, the following effects can be obtained. 1. The rooftop slab of the building has a three-layer structure consisting of a waterproof layer, a water storage tank, and a soil layer by the FRP waterproofing method. It is possible to provide a rooftop greening structure with a lawn, flowerbed or small garden built on the rooftop. it can. 2. Water-permeable non-woven fabric (5 mm to 10 m thick)
Since nonwoven fabric using m) as the soil outflow prevention sheet is used, it is possible to prevent the outflow of fine earth and sand. 3. The rooftop greening structure has a very light soil culture soil, is suitable as a soil for cultivating lawns, flowers and plants, and has excellent water retention. Therefore, since the rainwater that has passed through the culture soil is stored in the water storage tank portion, there is an advantage that there are few operations such as water injection and fertilization. 4. The infiltrated rainwater stored in the water storage tank pools on a reliable FRP waterproof layer (weatherproof, earthquake-resistant waterproofing method), and the surplus water is collected by the rainwater drain installed on the roof due to the slope provided on the roof of the building. It flows down naturally through a drainage pipe and is released to an external rainwater pipe. Excess water is generated when the water overflows the water tank, and the rainwater stored in the water tank is replenished as moisture for growing grass and other plants when the weather is dry. It can always be kept wet. 5. When water is sucked up from the reservoir to the soil layer,
Using a non-woven sheet of high water-retainable synthetic fiber cotton, which has no spoilage, on the RP water reservoir, and connecting it to a polyester receiving net that supports the soil, it is absorbed into the upper soil layer by capillary action. The water can be kept in a wet state, and if the drainage in the water storage tank is managed, the problem of grass blight can be solved. 6. In addition, it has effects such as being inexpensive to manufacture, easy to assemble because of a small number of parts, and economical.
