Description

[0001]
BACKGROUND OF THE INVENTION
The disclosed technology is a technical field of a system in which a sloped roof of a building (residential house, building, etc.) is vegetated, and precipitation is circulated by a pump using electric power from a solar panel provided on the roof. Belonging to.
[0002]
[Prior art]
As is well known, the remarkable improvement in civic life is supported by the rapid development of science and technology in industrial society, but the industrial society has a problem of recent imbalances with pollution problems and global environmental problems. Therefore, the development of a balance between the two is strongly demanded.
[0003]
Therefore, in Japan, where there are many mountain forests and special terrain conditions approaching complicated and long coastlines, it can be used for farming and livestock, housing and industrial facilities, regardless of whether it is urban or rural. The available plains are limited, and therefore these buildings are built in a centrally concentrated area, and therefore the green space is lost at the site of such an intensive and concentrated building. The photosynthesis effect is also weakened, the heat insulation effect and the sound insulation effect are reduced, various harmful effects due to the direct irradiation of ultraviolet rays on the roof, exhaustion and destruction of the roof surface over time, etc., and the aesthetic design of the appearance is reduced, etc. There are various problems, and there are technical and economic limits to solve the problem at the private enterprise level. Therefore, it is considered to deal with large capital by public institutions. Yes.
[0004]
By the way, when examining these densely built buildings from a bird's-eye view, most of the space is occupied by the roof. Therefore, from the construction state of the roof that connects the eaves, the above-mentioned problems of photosynthesis, heat insulation effect, sound insulation It can be seen that various problems such as deterioration over time of each roof surface due to reduced effects and weak earthquake resistance, destruction, and deterioration in appearance design are obvious.
[0005]
In addition, the roof of the building will inherently remove rain dew and provide heat insulation and sound insulation functions. However, due to the recent rise in industrial society, the concentration of buildings will significantly hinder this. It is becoming.
[0006]
Also, these roofs do not have any adjustment function for intensive precipitation, etc. Therefore, the rain falling from the roof inevitably causes the narrow streets to become flooded, so-called underfloor flooding and other social problems Has also come to arise.
[0007]
Moreover, because of the adjacent roofs due to the state of construction of such a dense and intensive building, deterioration of the appearance of the roofs has brought about unfavorable conditions from the viewpoint of mental health for residents and passers-by.
[0008]
On the other hand, in order to prevent the extreme cold in winter in countries in the northern regions such as Ireland and Scandinavia, and as a countermeasure to prevent the rise in indoor heat in the extremely hot countries such as Africa, The greening means on the roof has been used for a long time, and even in Japan, the Shiba ridge was used as a holding means for the so-called thatched roof ridge part. However, due to the momentum of modern buildings that accompany this, the rooftop greening problem has recently been recognized in terms of harmony with the natural environment, and roof greening has been actively adopted again. In particular, in Germany in Europe, it seems that public institutions are positioned as environment-related industries and have adopted incentive policies. Performs a special edition of greening, have come to capture the technology to perform the vegetation on the roof as the eco-technology boom.
[0009]
In addition, the rooftop greening makes the location of dense and intensive buildings unavoidable, while re-establishing green spaces that will be lost and making effective use of precipitation as much as possible. It also has a sound insulation function, a dust filtering function, reduces carbon dioxide, releases oxygen by photosynthesis, etc., protects the roof surface from ultraviolet rays, and protects the roof surface from extreme temperature changes In addition, the benefits of improving the mental health of residents and passers-by by beautifying the design appearance and by harmonizing with the surrounding environment through greening are highlighted.
[0010]
However, according to the prior art shown in FIG. 6 , for example, according to the prior art shown in FIG. 6 , a waterproof sheet or a waterproof board 2 is stretched on the upper surface of the roofing material 1, and the headboard 3 is set up at the end. A technique has been developed in which a cultivated layer 7 is laid and set on the earth brick 6 via the grid pallet 5 via the crushed stone 4 and the like, and a predetermined vegetation 8 is applied to the cultivated layer 7.
[0011]
However, the seed technique is usually applied to a flat roof, and has a drawback of lacking in versatility such that it cannot be applied to a gable type or a single-flow type sloped roof . Further, difficulty there Ru such an unsuitable construction for greening of soil layer 7 is less than 10cm thin layer. Furthermore , there was a demerit that water adjustment technology against precipitation etc. could not be dealt with.
[0012]
In addition, there are also imported roofs made in Germany, etc., but such imported roofs are often used as so-called flat roofs, and there is a disadvantage that they are not necessarily suitable for sloped roofs of ordinary houses. there were.
[0013]
