DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening structure on a roof of a building such as a house or a building, and more particularly, by constructing a farm, a flower bed or a small garden on the roof of a house or a building or on a veranda by simple means. The present invention relates to a greening structure for cultivating flowers and 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 roof of various buildings. These small gardens and flowerbeds form an enclosure on the rooftop with concrete and other materials, lay the soil in these enclosures, plant flowers and plants, and spray water and chemical fertilizers for cultivation. In most cases, this is done.

[0003] By cultivating flowers and plants on the roof of the building in this way, the summer has the effect of preventing the reflection of sunlight and suppressing the rise in temperature in the building. Also, due to the recent pollution of air in large cities, greening the rooftops of various buildings has the effect of improving the air purification and landscape, and promoting greening of many buildings. It is the present situation that is desired. The same can be said for the rooftop or veranda of a residence.

[0004]

As described above, the material for forming a small garden or flower bed on the roof of a building such as a house or a building must be lightweight in order to reduce the load on the building. Requirements. Furthermore, there is a problem that the culture medium such as soil is easily dried on the roof due to the wind, and the surface layer of the culture medium is scattered by the strong wind.

Furthermore, heavy use of chemical fertilizers on the roof of buildings such as dwellings and buildings has a disadvantage that concrete and other aggregates are deteriorated. In addition, during rainfall, it is required that excess rainwater stored in the flowerbed be drained smoothly. When soil or the like is mixed in the drainage, it flows as active water and causes a problem that the drainage pipe leading to the ground may be clogged.

[0006] Furthermore, it is difficult to obtain a garden of sufficient size in an urban area with a high land price, and there is little opportunity to get close to green and get pleasure in growing plants and growing crops. Therefore, even if there is no garden, if you can build a farm, etc. using the rooftop or veranda, grow flowers and trees, or grow vegetables, you can refresh, relieve stress, blur and bedridden It is thought that it becomes prevention of the like.

Accordingly, the present invention employs lightweight materials to reduce the load on the building, prevent the soil from scattering due to the wind, and smoothly drain the rainwater stored in the flowerbed during rain. It is an object of the present invention to provide a rooftop greening structure of buildings such as dwellings and buildings that can be used.

Is formed to penetrate through.

Reference numeral 9 denotes a waterproof mortar trowel formed on the upper surface of the concrete wall portion 2. Reference numeral 10 denotes a state in which the lower end portion is embedded in the wall portion 2 and has a height of, for example, about 1000 mm. It is a blindfold fence erected. The blind fence 10 has a function of improving appearance by employing a resin-coated member and preventing scattering of the artificial culture soil 7 due to strong wind.

According to such a greening structure on the roof, at the time of construction, first, the concrete 1
Then, an appropriate area on the holding concrete 1 is selected and the wall 2 is erected. A waterproof mortar trowel finish 9 is applied to the upper surface of the concrete wall portion 2, and a waterproof sheet 5 is stretched over the inner wall surface of the wall portion 2 to make a metal waterproof presser 5 a.
Then, the waterproof sheet 5 is fixed to the upper inside of the wall 2.

A lower drainage hole 8 is previously opened in the lower portion of the concrete wall portion 2, and the lower drainage hole 8 is provided at the time of construction.
A stainless steel wire net 11 having a mesh of about 3 mm is attached from the inside.

Next, a foundation soil 3 as a cushion material is laid all over the upper surface of the holding concrete 1. Further, a small corrugated glass fiber reinforced polyester plate 4 is laid on the upper surface of the basic soil 3 as a waterproof layer, and the overlapped portion is fixed with a wooden piece on the back and nailed.

On the glass fiber reinforced polyester plate 4, a large soil washed in advance with water is laid to form a water retaining layer 6 having a thickness of about 50 mm. After the super lightweight artificial culture soil 7 is put on the water retaining layer 6 to a thickness of about 400 mm, a blindfold fence 10 is set up on the upper part of the wall 2 while maintaining a height of about 1000 mm to construct a flower bed or the like. Construction is completed.

The above-mentioned artificial culture soil 7 is suitable as a soil for cultivating flowers and plants, and weighs one-half that of natural soil when wet.
To 1/3 of the weight and excellent in water retention.
Since the rainwater that has passed through the artificial culture soil 7 is stored in the water retaining layer 6, there is no need to perform operations such as injecting water into the artificial culture soil 7 or performing excessive fertilization even in normal times.

In case of heavy rain, excess rainwater is received by the glass fiber reinforced polyester plate 4 as a waterproof layer,
The water is guided to a drain pipe (not shown) provided on the roof of the building through the water drain hole 8. Originally, the concrete constituting the flat part of the rooftop of the building is designed with a predetermined gradient given in advance in consideration of drainage. Therefore, as described above, the excess rainwater is applied to the waterproof sheet 5 along the gradient. Through the drain hole 8 under the water, and naturally flows down to the drain pipe.

The blindfold fence 10 not only enhances the appearance but also prevents the surface layer of the artificial culture soil 7 from scattering due to strong wind.

Although the above embodiment has been described by taking the roof of a building as an example, the present invention can be applied to a roof of a residence or a veranda as it is, and a general two-story or three-story general residence is used. It is also suitable to carry out on the rooftop.

[0030]

As described above in detail, according to the rooftop greening structure of the present invention, the base soil, the waterproof layer, the waterproof sheet, the water retaining layer, and the artificial soil used are all lightweight members. Therefore, the load on a building such as a house or a building is reduced, and a relatively large-area farm, flower bed or small garden can be constructed without damaging the building.

The artificial culture soil used is not only lightweight but also suitable for cultivating flowers and plants.
In addition, since rainwater that has passed through the artificial culture soil is stored in the water retaining layer, it is not necessary to inject water into the artificial culture soil or excessive fertilization, and there is no fear that concrete and other aggregates caused by heavy use of chemical fertilizers are deteriorated.

The surplus rainwater is received by the waterproof layer and naturally flows down to the drain pipe through the water drain hole, so that the water stored in the flower bed can be smoothly drained. At this time, since the water retaining layer and the artificial culture soil have been washed beforehand and used, there is no occurrence of active water due to the contamination of the drainage with the soil and the like, and there is no occurrence of a situation where the drain pipe leading to the ground is clogged.

In addition, the appearance is improved by erection of the blind fence while maintaining an appropriate height above the wall, and especially under the condition that the soil and the like are easily dried by the influence of the wind on the roof of the building. Even if it is, the scattering of the artificial culture soil can be prevented.

According to the present invention, greening of houses and building roofs is possible in a relatively short construction period, and the use of lightweight materials at the time of construction reduces the load on buildings and reduces the wind. It is possible to provide a rooftop greening structure capable of smoothly draining rainwater stored in a flowerbed at the time of rainfall without scattering of soil due to the influence.

Furthermore, even if there is no garden, a farm or the like can be constructed using a rooftop or a veranda, and flowers and trees can be grown and vegetables can be cultivated.
It is thought that it will also relieve stress and prevent blurring and bedriddenness.
