BACKGROUND OF THE INVENTION
The present invention relates to a rooftop greening system provided on a rooftop of a building or the like for the suppression of a heat island phenomenon in an urban area or the like, and a removal method thereof, in particular, a system capable of easily performing renewal work and the removal thereof. Regarding the method.
[0002]
[Prior art]
In order to suppress the heat island phenomenon in urban areas, a greening part such as an artificial garden is installed on the roof of a building. When installing this greening section, in general, after providing a waterproof layer with a waterproof sheet on the roof of the building and taking sufficient waterproof measures, embankment of the soil on the waterproof layer and vegetation on the soil It is done. Here, with regard to the soil, in order not to give a heavy weight load to the rooftop of the building, and to clear the weight limit of the rooftop, a special lightweight soil is used, or its thickness is reduced. For example, the weight is reduced by forming a thin layer of 10 cm or less.
[0003]
[Problems to be solved by the invention]
However, when the weight of the soil was reduced, the following problems occurred. That is, since the load of the soil is very light, there is a possibility that the soil will be lifted when subjected to a strong wind. In particular, the roof of the building was in an environment where the wind was stronger than the ground and it was easy to lift.
[0004]
Therefore, it has been proposed to fix the entire soil to the rooftop using an appropriate fixing device. The fixing device is fixed to a roof slab surface, a parapet, or the like, and thereby, it is possible to green the roof even to a building having a height of several tens to several hundreds of meters.
[0005]
However, in this case, it is necessary to provide fixing holes in the waterproof layer, and there arises a problem that many fixing holes remain when the greening portion is rearranged or renovated. If the greening part is re-installed in a state where the hole is left as it is, problems such as the possibility of rainwater or the like entering the building from the hole occur. For this reason, it is necessary to perform a process such as repairing to close the hole or re-applying a waterproof layer.
[0006]
On the other hand, when fixing a fixing device to a parapet, it is not necessary to provide a hole in the waterproof layer, but a wire etc. must be stretched up to the parapet, which may interfere with maintenance work on the roof or in an emergency. There was a risk of adversely affecting fire fighting activities. For this reason, it has been extremely difficult to employ a configuration in which the fixing device is fixed to the parapet.
[0007]
Thus, in the conventional rooftop greening system, how to fix the greening part to the rooftop has been a big problem.
[0008]
The present invention has been made in view of such circumstances, and the purpose thereof is a rooftop greening system that can fix a greening part without opening a hole in a waterproof layer and can easily perform renewal work, and It is to provide the removal method.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Embodiments of a rooftop greening system and its removal method according to the present invention will be described below in detail with reference to the accompanying drawings. 1 to 11 show an embodiment of a rooftop greening system according to the present invention.
[0017]
FIG. 1 shows a configuration of a rooftop greening system according to the present embodiment. This rooftop greening system includes a greening base 10 and a potted plant 40 on a waterproof layer 4 disposed on a roof slab 2 of a rooftop 1 of a building. These greening base 10 and potted plant 40 are fixed via a block 30 installed on the waterproof layer 4. The greening base 10 and the potted plant 40 correspond to the greening part in the present invention, and the block 30 corresponds to the fixing member in the present invention.
[0018]
The waterproof layer 4 is provided by laying a waterproof sheet 5 on the roof slab 2. The waterproof sheet 5 is a sheet-like member having a thickness of about 1.2 mm to 2.5 mm, for example. The waterproof sheet 5 is formed of a material that can be fused with other members, such as a thermoplastic resin material, and can be melted by heat and bonded to the other members. In this embodiment, the waterproof sheet 5 is formed of a thermoplastic resin material based on a soft olefin. The thermoplastic resin material based on this soft olefin is a material that has excellent durability and waterproofness, is excellent in root resistance and flame resistance, and can exhibit waterproof performance over a long period of time. Furthermore, since this material does not contain chlorine, heavy metals, halogens, etc., it does not generate dioxins even when incinerated, and is excellent in terms of environment, such as no heavy metal contamination. As the waterproof sheet 5, for example, “Sanaroof TS” or “Sanaroof TG” manufactured by Hitachi Cable, Ltd. (sold by Power and Comtech) can be used. In addition, as the waterproof sheet in the present invention, a waterproof sheet mainly composed of acrylic resin (for example, trade name “Rivet Roof EX” manufactured by Akiyamade Co., Ltd.) or a waterproof sheet made of vinyl chloride resin may be used. it can.
[0019]
The greening base 10 is formed to have a thickness of, for example, 15 cm or less, and as shown in FIG. 2, a water retention sheet 12, a drainage layer 14, and a water guide sheet 16 are laminated in order from the waterproof layer 4 side (lower side). Configured. Further, on the water guide sheet 16, a soil 18 is formed with a predetermined thickness, and a planting 20 is applied on the soil 18. A water supply pipe 22 is embedded in the soil 18, and water is supplied from the water supply pipe 22 to the water guide sheet 16. Further, a three-dimensional structure net 24 is embedded in the soil 18.
[0020]
The water retentive sheet 12 is a sheet-like member made of a woven or knitted fabric having high water retentivity, and is formed, for example, by weaving PET raw yarn, impregnating an uncrosslinked resin, and causing a crosslinking reaction. Alternatively, the water retention sheet 12 can also be formed by weaving a PET raw yarn after wetting it, or by weaving a slit made of a water-soluble resin. Since the water-retaining sheet 12 is always wet with moisture, it has a role as a root-preventing sheet for preventing planting rooting at this position. Moreover, the thermal buffering function of the greening base 10 can be enhanced by the high water retention property of the water retention sheet 12. Such a water-retaining sheet 12 can be handled as a lightweight sheet in a non-hydrated state, and can be easily laid. In the present embodiment, for example, trade names “SMAT-A, SMAT-B, SMAT-C, SMAT-D, SMAT-E” manufactured by Seisei Textile Co., Ltd. are used as the water retention sheet 12.
[0021]
The drainage layer 4 is composed of a drainage member made of a mat with a thickness of about 1 cm, which is composed of fibers having a flat three-dimensional stitch structure and contains continuous voids. In this embodiment, as the drainage member, for example, The brand name “Hetimaron” manufactured by Shinko Nylon Co., Ltd. is used. Such a drainage layer 4 has a function of permeating moisture and discharging excess moisture in the water guide sheet 16 downward, entangled with the roots of the planting, stabilizes the rooting, and forms an air layer. And it has a function to prevent root rot due to excessive moisture during the rainy season.
[0022]
The water guide sheet 16 is a sheet made of woven cloth or the like, and permeates the irrigation supplied from the water supply pipe 22 to one surface by capillary action, and exudes into the upper soil 18 from the entire surface to supply water. It is like that. Thereby, it is not necessary to perform excessive irrigation as compared with the case of watering with a conventional sprinkler or hand, and the moisture of the soil 18 can be made uniform naturally.
[0023]
The soil 18 is formed into a thin layer, for example, as a layer having a thickness of about 5 cm. The soil 18 is composed of, for example, a subsoil of weathered volcanic ash, charcoal, or mixed soil obtained by mixing zeolite with an appropriate composition ratio. Here, the volcanic ash weathered soil has excellent water retention and adsorbability of anions such as nitric acid and sulfuric acid. In addition, charcoal is mixed for the purpose of creating a living phase of microorganisms using its porous voids, grows nitrogen-fixing bacteria to take in nitrogen in the atmosphere and supply it to plants, It is possible to maintain the growth and growth of plants even in the soil. In addition, zeolite has a strong adsorption performance for cations such as ammonia, moisture, and various gases due to its fine porous structure, and because it is negatively charged, various types such as sodium, potassium, calcium, magnesium, etc. It has the function of adsorbing and holding cationic fertilizer components and supplying these fertilizer components as needed by the plant. As this zeolite, for example, the trade name “Tamalite” of Okutama Kogyo Co., Ltd. is preferably used. These composition ratios are preferably set so that the pH of the soil 18 becomes a neutral value, for example, volcanic ash weathered soil 8: charcoal 0.5-1: zeolite 1-1.4 by weight ratio. Is done. According to such a composition ratio, if the soil layer thickness is 5 cm and the temporary specific gravity is 1, the weight is 50 kg / m. ² Thus, lightweight soil can be realized.
[0024]
Note that a soil fixing agent may be blended in the soil 18. The soil fixing agent is a milky white emulsion made of a polymer glue, for example, ethylene-vinyl acetate copolymer resin, and the soil 18 is impregnated by uniformly spraying this liquid on the surface after the soil 18 is formed. The soil fixing agent impregnated in the soil 18 fixes soil particles, prevents soil outflow while ensuring water absorption, and secures the rooting of the vegetation. As this soil fixing agent, for example, it is preferable to use a trade name “Polysol EVA P-7” manufactured by Showa Polymer Co., Ltd.
[0025]
In addition, a humidity sensor or the like is embedded in the soil 18, and an automatic water supply facility is provided for automatically supplying a certain amount of water through the water supply pipe 22 when the sensor detects a predetermined dry state. May be.
[0026]
The three-dimensional structure net 24 is a net made of a synthetic resin having a mesh structure, and is known as a member that prevents soil loss due to surface erosion due to rainwater, wind erosion due to a windbreak effect, and the vegetation is entangled with the net 24. Prevent flaking of vegetation due to wind and other effects. Moreover, since the three-dimensional structure net 24 is embedded in the soil 18, deterioration of the three-dimensional structure net 24 due to the ultraviolet rays of sunlight is prevented. As the three-dimensional structure net 24, for example, a trade name “3D-TECHNONET” of Asahi Technos Co., Ltd. may be used.
[0027]
In addition, the greening base in this invention is not restricted to the said structure. For example, if water is supplied to the water guide sheet 16 using a gutter or the like, the water supply pipe 22 may be omitted, and if the amount of water supplied to the soil 18 through the water guide sheet 16 can be sufficiently adjusted, The layer 4 may be omitted, and the water-retaining sheet 12 may be omitted if root prevention is not particularly necessary or if root prevention is possible by other means. If the soil 18 is sufficiently integrated with a soil fixing agent or the like, the three-dimensional structure net 24 may be omitted. In addition to the soil 18, a water pumping block, chip bricks, and the like may be disposed on the water guide sheet 16.
[0028]
