Abstract

<P>PROBLEM TO BE SOLVED: To provide greening for reducing a total cost by minimizing planting soil, reducing the number of working days, and simplifying work (kind of construction) in rooftop greening. <P>SOLUTION: The greening is such that a hard water retaining material (porous ceramics or the like) with good handling is used, instead of soil, in order to supply water necessary for plant growth (photosynthesis), and work is easy because it is required only to lay the hard water retaining material (porous ceramics or the like) on a place set with a waterproof sheet, and when a construction to renew rooftop waterproof is required, it is required only to easily remove the hard water retaining material (porous ceramics), which is to be reused thereafter, and planting soil is put only a joint part between the hard water retaining materials (porous ceramics or the like), and, as plants corresponding therewith, creeping plants (Phyla nodiflora, Ficus nipponica, Hedera rhombea, lawn or the like) are used. The creeping plants sprout creeping stems and adhesive roots and extend on the hard water retaining material, and the adhesive roots become aerial roots, and also absorptive roots by accumulation of organic substances, and go into also the hard water retaining material. Water necessary for plants is supplied from the hard water retaining material to the planting soil, and absorbed also from the absorptive roots going into the hard water retaining material. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to greening by a fluffy plant using a hard water retaining material (porous ceramics or the like).

  In order to alleviate the heat island phenomenon, there are various greening technologies for rooftop greening and wall greening.

  In conventional rooftop greening, the planted soil is averaged over the entire green area, and greening is performed. Soil is necessary for securing moisture necessary for plant growth. However, carrying a large amount of soil is costly and takes many days. Therefore, it is not easy to green the existing rooftop.

  For rooftop greening, it is first necessary to install waterproofing and root-proof sheets. Planting on the soil with the soil all over the ground requires landscaping (planting) technology. Since the tarpaulin installation work, etc. and the planting are different, it is expensive.

  The waterproofing function of the rooftop waterproof sheet or the like always deteriorates over time. When renewing the waterproof function, the roof garden must be removed. The burden on the environment and construction costs due to waste is large, which hinders rooftop greening.

  Minimize planting soil, and reduce the total cost by reducing the work days and simplifying work (work type).

  Provided is an environment capable of supplying water necessary for plant growth (photosynthesis) while achieving the above-mentioned object.

  When renewing rooftop waterproofing, simply removing hard water retaining material (porous ceramics, etc.) makes it easy and easy to install. In addition, since hard water retaining materials (porous ceramics) and the like can be reused, it is possible to reduce environmental burden and construction costs due to waste.

Means to solve the problem

  In order to solve the above-described problems, the present invention uses a hard water-retaining material (such as porous ceramics) that is easy to handle instead of soil to secure moisture necessary for plant growth. It is only necessary to lay a hard water retaining material (such as porous ceramics) on a waterproof sheet or the like, and work can be performed easily. It can also be easily removed and reused.

  In order to minimize planting soil, planting soil is limited to joints between hard water retaining materials (porous ceramics, etc.), and fluffy plants (Iwadaresou, Itabikazura, Kizuta, etc.) can be used as plants that can handle it. use. A fluffy plant grows with a fluffy stem and sticking root on a hard water retaining material. Adherent roots become aerial roots and become absorption roots due to the accumulation of organic matter, etc., and also enter hard water retaining materials. Moisture necessary for the plant is supplied from the hard water-holding material to the planting soil, and is also absorbed from the absorption roots that have entered the hard water-holding material.

The invention's effect

  As described above, according to the present invention, greening of a rooftop or the like can be performed with less planting soil. In addition, by not requiring a landscaping (planting) technique, it is possible to reduce the total cost by reducing the number of working days and simplifying the work (work type). Since rooftop greening and the like can be easily performed, the spread of rooftop greening and the like will be promoted.

  The entire surface of the hard water retaining material can be covered with the minimum planting soil. C3 plants, fluffy plants (Iwadares, Itabikazura, Kizuta, turf, etc.) contribute to lowering the temperature of the coated surface due to transpiration and energy consumption for photosynthesis, and mitigating the heat island phenomenon. .

  A waterproof sheet for waterproofing is required on the roof, but deterioration due to ultraviolet rays is inevitable. According to the present invention, the waterproof sheet is covered, and the waterproof sheet or the like lasts for a long time.

  Since it is only necessary to install it on the waterproofing layer on the roof, if it is necessary to renew the waterproofing of the roof over time, it is sufficient to simply remove the hard water retaining material (porous ceramics, etc.). Available. It is also a rooftop greening that is low in construction costs and adapted to a recycling society.

BEST MODE FOR CARRYING OUT THE INVENTION

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 are plan plan views of joints as a hard water retaining material and planting soil. FIG. 3 is a sectional view thereof.

  Although the embodiment of the present invention has been described with reference to the drawings, the present invention is not limited to this embodiment.

Claims (4)

  The present invention, in order to minimize planting soil in the greening of the roof, the planting soil is only a joint portion between hard water retention materials (porous ceramics, etc.), in order to ensure the moisture necessary for the growth of the plant, Use hard water-retaining materials (porous ceramics, etc.) that are easy to handle, and use fluffy plants (Iwadaresou, Itabikazura, Kizuta, turf, etc.) as plants that can handle them. A fluffy plant grows with a fluffy stem and sticking root on a hard water retaining material. Adherent roots become aerial roots and become absorption roots due to the accumulation of organic matter, etc., and also enter hard water retaining materials. Moisture required by plants is supplied to planting soil from hard water-retaining materials and is also absorbed from absorption roots that have entered the hard water-retaining materials.   According to the present invention, it is only necessary to install a hard water retaining material (porous ceramics, etc.) and a small amount of planting soil for joints on a waterproof sheet, etc., and requires a landscaping (planting) technique. Greening with fluffy plants using hard water retaining material, which can reduce the total cost by reducing the number of working days and simplifying the work (work type). The waterproofing function of the rooftop waterproof sheet or the like always deteriorates over time. When renewing the waterproof function, the roof garden must be removed. The burden on the environment and construction costs due to waste is large, which hinders rooftop greening. The present invention can be constructed simply and simply by removing the hard water retaining material (porous ceramics, etc.) during the roof waterproofing renewal work. After that, greening with fluffy plants using a hard water retaining material that can be reused again. C3 plants, fluffy plants (Iwadares, Itabikazura, Kizuta, turf, etc.) contribute to lowering the temperature of the coated surface due to transpiration and energy consumption for photosynthesis, and mitigating the heat island phenomenon. Greening with fluffy plants using a hard water retention material characterized by things.
