Description

  The present invention relates to a rooftop greening construction system.

  In recent years, the demand for urban greening has increased, and in response to this, technology for greening by installing vegetation panels on the roof of buildings has been developed and is becoming popular. This kind of rooftop greening suppresses the so-called heat island phenomenon by cultivating plants on the rooftop of the building and mitigating the absorption and release of heat from the rooftop. It is also intended to improve the environment against air pollution and the like through cultivation.

  Even when rooftop greening is performed, the soil is basically the basis for planting, as in the case of greening other places. It must be above a certain level. However, in the case of rooftop greening, if the soil becomes thick, the load of soil on the roof cannot be ignored from the viewpoint of the load on the building. For this reason, generally the load capacity of the soil concerning a rooftop part is defined, and the tolerance standard of the load load concerning a rooftop part tends to become severe in recent years as the technique of rooftop greening spreads.

  For this reason, in rooftop greening technology, so-called thin-layer greening that does not apply a large load on the rooftop part is often used. Conventionally, patent applications such as the following Patent Document 1 and Patent Document 2 have been filed as techniques relating to such thin layer greening.

  Patent Document 1 and Patent Document 2 relate to a thin-layer greening technique using a sedum plant. Sedum plants do not require much irrigation compared to other plants, and grow even when the soil layer is thin, so it can be said that it is the most suitable plant species for thin-layer greening.

  However, rooftop greening has been implemented as a countermeasure against heat island as described above because the temperature of the atmosphere in the vicinity of the roof is lowered by transpiration of plant water, and a large amount of transpiration is required to effectively produce this effect. It is originally preferable to use plants. In this regard, Sedum plants are originally plant species that do not have a large amount of transpiration, so they cannot be said to be optimal plant species for heat island countermeasures.

  In addition, the limited plant species also makes it difficult to realize the diversity of plants that greening should originally be aimed at. In this sense, the development of rooftop greening using plant species other than Sedum plants is desired.

  In addition, thin-layer greening technology focuses on reducing the thickness of the layered soil as much as possible, so the greening system constructed on the rooftop will also be flat, with three-dimensional and changing forms. Since it is difficult to form a roof, there is a limit to the scenery that can be revealed by rooftop greening.

Japanese Patent Laid-Open No. 11-172706 JP 2002-272259 A

  The present invention has been made to solve such problems, and has an effect of relieving the heat island phenomenon as compared with the conventional rooftop greening technology. The space can be secured in a large space, and it is possible to take energy-saving measures such as cooling the building and reducing the air-conditioning load on the downstairs. It is an object to provide a rooftop greening system that can be put out.

  In order to solve such a problem, the present invention provides a container part that can accommodate a planting base such as soil and a plant, a standing part on a rooftop installation surface, and the installation surface and the container part. A planting unit is configured by supporting legs that are attached to the container part and support the container part so that a space part can be formed therebetween, and the height of the container part is changed by changing the length of the supporting leg. The present invention provides a rooftop greening construction system characterized in that a large number of planting units adjusted in different positions are installed and constructed on the rooftop installation surface.

  A space portion formed between the installation surface of the roof and the container portion is formed as an enclosed space portion that is totally surrounded by plants accommodated in the container portions of a large number of planting units, and the enclosed space It is also possible to provide an opening / closing means for opening / closing the enclosed space portion on one end side of the portion. As such opening / closing means, for example, a louver is used. It is also possible to provide a water storage panel for storing water for irrigating the planting base and the plant housed in the container part of the planting unit.

  In the case of providing such a water storage panel, a plurality of planting units are arranged so that the height position becomes lower sequentially from the planting unit having a higher height position of the container part, and the water stored in the water storage panel is irrigated. Water is pumped up and supplied in cascade from the planting unit with the highest height of the container to the planting unit with the lowest height of the container, and then returned to the water storage panel. The water is transferred to the irrigation pump side by the slope of the bottom surface of the water storage panel, pumped up again by the irrigation pump, and sequentially supplied in a cascade state to a plurality of planting units having different height positions of the container part. It is also possible to configure such that water is automatically and circulated to a plurality of planting units having different height positions of the container portion.

  As described above, the present invention is a container part that can accommodate a planting base such as soil and a plant, and a space provided between the installation surface of the roof and the container part. The planting unit is composed of support legs that are attached to and supported by the container part so that the part can be formed, and the height position of the container part is adjusted by changing the length of each support leg. Since many planted units were installed and constructed on the rooftop surface, a three-dimensional and fluctuating landscape that cannot be imagined depending on the conventional thin greening technology, etc. There is an effect that can be.

  In addition, a large number of planting units adjusted so that the height positions of the container portions are different are installed on the installation surface of the roof, and the planting bases and plants accommodated in the container portions having different heights, as well as the containers As a whole, a forest-like environment is formed on the rooftop part by the space part formed between the part and the installation surface of the rooftop, so that, for example, in the summer, a shaded part is a large space. Therefore, energy saving measures such as cooling the building and reducing the air conditioning load on the downstairs can be achieved.

  In addition, the shaded area is formed on the roof with a large space, and plants with a transpiration effect are accommodated in the container part of the planting unit, thereby reducing the heat island phenomenon compared to conventional rooftop greening technology. This will significantly improve the effect.

  As described above, the roof greening construction system of the present invention includes a container portion that can accommodate a planting base such as soil and a plant, a rooftop installation surface, and the rooftop installation surface and the container. A planting unit is constituted by a support leg that is attached to the container part and supports the container part so that a space part can be formed between the container part and the container by changing the length of the support leg. A large number of planting units adjusted so that the height positions of the parts are different from each other are installed and constructed on the installation surface of the rooftop.

  The large number of planting units are roughly classified into shrub units, herbaceous units, and basin units according to the types of plants accommodated therein. The shrub unit is for planting plants such as shrubs and ground cover, the herbaceous unit is for planting herbs, and the basin unit is for planting aquatic plants. Of course, it is also possible to constitute planting units other than these three types of units.

In the roof greening construction system of the present invention, in addition to the planting unit as described above,
For example, a management road unit, a solar panel unit, and a water storage panel are provided.

  FIG. 1 is an exploded perspective view schematically showing a rooftop greening construction system according to an embodiment of the present invention disassembled for each group of components by using these components.

Shrubs, ground cover, etc. are planted in the container part constituting the shrub unit, and grass is planted in the container part constituting the herb unit. Although the kind of planting base is not particularly limited, it is desirable to use lightweight artificial soil in consideration of the load on the roof. If high-performance lightweight artificial soil is used, trees can be planted even in thin layers. Planting shrubs and ground cover plants with such a shrub unit enables planting to produce seasonal scenery.

  Reference numeral 4 denotes a basin unit. An aquatic plant will be planted in the container part which comprises a basin unit. Therefore, an aquatic plant that does not have a planting base and can grow only with water does not need to accommodate the planting base in the container portion of the basin unit. However, depending on the type of aquatic plant, it is also possible to accommodate a planting base.

As will be described later, in addition to being able to circulate and use for irrigation, it can produce effects as a waterscape. In summer, a cool breeze can flow around. The water 6 is schematically shown as a perspective view in FIG.

Reference numeral 7 denotes a management road unit. By arranging a large number of management road units, a management road is constructed. This management road unit 7 has FRP on the top surface.
It is a unit that can be walked by installing a grating. Since the grating itself allows light and rain to pass, it can be planted in the lower part.

  Reference numeral 8 denotes a solar panel unit. By combining the solar panel unit 8, a solar panel 15 described later is configured. The electric power generated by the solar panel can be used as a power source for an irrigation pump as will be described later, and can also be stored and used for night illumination. It is also possible to use it as an illumination unit by attaching glass or the like on the side surface and installing illumination inside.

  In addition to such a unit, a root prevention sheet or the like is also provided. In FIG. 1, 9 is the root prevention sheet | seat, 10 shows the roof surfaces, such as a building.

  FIG. 2 is an exploded perspective view showing the configuration of the planting unit more specifically. The container part 1 of a planting unit is formed in the substantially shallow box shape which an upper surface opens as shown to the same figure. Moreover, the planting base | substrate 3 accommodated in the container part 1 is shown by the same figure. One planting base 3 in FIG. 2 is for planting the shrub 11, and the other planting base 3 is for planting the herb 12.

The support legs 2 are attached to the four corner portions of the container portion 1. In FIG. 2, the container part 1 in which the planting base 3 is not accommodated shows a support leg 2b to be newly connected in addition to the support leg 2a already attached. By connecting the support legs 2a and the support legs 2b, the support legs 2 that are longer than the container 1 in which the planting base 3 on which the shrubs 11 and the herbs 12 are planted are accommodated in FIG. As a result, the height of the planting unit will be adjusted.

  FIG. 3 is a schematic cross-sectional view showing an example of the overall arrangement of the rooftop greening construction system of the present invention. As shown in FIG. 3, in the rooftop greening construction system, the water storage panel 5 is disposed in a substantially central region. A plurality of basin units 4 are arranged in the further central portion of the water storage panel 5, and aquatic plants 13 are planted in the basin units 4. Furthermore, on both sides of the portion where the basin unit 4 is disposed, a large number of planting units in which the shrubs 11 are planted are disposed, and planting units in which the herbs 12 are partially planted are disposed. Has been.

  As shown in FIG. 3, the planting units disposed on both sides of the basin unit 4 are disposed so that the height gradually increases from the inner planting unit to the outer planting unit. Yes. Adjustment of the height of these many planting units is performed by appropriately connecting a plurality of support legs 2 having different lengths as described above, and the number of connected support legs 2 is different.

  Further, the management road unit 7 is also partially arranged. In the portion where the management road unit 7 is disposed, a management road for managing the rooftop greening system is formed. Further, on one end side of the system, although not shown, an open / close louver for opening and closing the system enclosed space and circulating air is disposed.

FIG. 4 is a schematic side view for explaining the irrigation circulation system, and shows a state in which each unit in the vicinity of the water storage panel 5 is more specifically enlarged.
In the irrigation circulation system shown in FIG. 4, irrigation is performed by a solar irrigation pump 14, and a solar panel 15 constituted by the solar panel unit 8 is used as a drive source of the irrigation pump 14. . The solar panel 15 is operated by sunlight. The operation of the irrigation pump 14 by power generation in the solar panel 15 is controlled by a timer 16. Water is supplied from the water supply pipe 17 to the water storage panel 5. The water supply pipe 17 is opened and closed by an electromagnetic valve 18, and the electromagnetic valve 18 is controlled by a timer 19.

  Each planting unit shown in FIG. 4 is configured to have a different height. As described above, the height is adjusted by means for connecting the support legs 2 attached to the container portion 1. In FIG. 4, the support legs 2 are connected via the flanges 20 formed on the support legs 2. The connected state is illustrated. Further, a state in which the support legs 2 of the planting units adjacent to each other are bound by a binding band 21 is also illustrated.

  In the example of the system of FIG. 4, a planting unit having a high height is positioned on the upstream side, and the height of the planting unit is gradually decreased from the upstream side to the downstream side in a total of seven stages. The state where the planting unit is arranged is shown.

  In the system of FIG. 4, planting units in which the herbs 12 are planted are arranged in the first, third, and fifth stages from the upstream side, and the second, fourth, and sixth stages from the upstream side. In the eyes, planting units are planted with shrubs. Furthermore, a basin unit 4 in which aquatic plants are planted is arranged on the seventh stage. The seventh-stage basin unit 4 is supported by the lower support legs 2 and is set to a height close to the height of the water surface stored in the water storage panel 5, and as a result, the water stored in the water storage panel 5. Can enter into the basin unit 4, whereby the basin unit 4 is in a so-called wetland state. As shown in the figure, lightweight artificial soil as a planting base 3 is accommodated in the container part 1 of each planting unit.

  And the water storage panel 5 is arrange | positioned in the range of the area | region where the planting unit of a total of 7 steps | paragraphs was arrange | positioned. The bottom surface of the water storage panel 5 is formed to be slightly inclined from the downstream side toward the upstream side.

  Irrigation is performed by the irrigation pump 14 in each of the seven planting units in total. That is, the water pumped up by the irrigation pump 14 activated by the power generation of the solar panel 15 is first supplied to the first-stage planting unit via the water supply pipe 22, and then gradually decreases in height from the upstream side to the downstream side. It will be sequentially supplied in a so-called cascade state to the second to seventh stage planting units.

  In this way, a part of the water pumped up by the irrigation pump 14 is sequentially supplied to each planting unit in a cascade state, and the other water falls directly from each planting unit to the water storage panel 5. In any case, water from the irrigation pump 14 is supplied to each planting unit evenly, and after the supply, the water is returned to the water storage panel 5 as a result.

  In this case, since the bottom surface of the water storage panel 5 is formed to be slightly inclined from the downstream side toward the upstream side as described above, the water returned to the water storage panel 5 has this slight inclination gradient. Is gradually returned upstream. And it will be pumped with the said irrigation pump 14, will be again supplied to the 1st stage planting unit, and will be sequentially supplied to the 2nd stage-the 7th stage unit again in a cascade state again. .

  In this way, the water supplied from the water supply pipe 17 to the water storage panel 5 is circulated and used for the plants installed in a total of seven stages as described above. As described above, in the present embodiment, it is possible to save management from the viewpoint of water circulation such as irrigation, and rainwater and surplus water are efficiently stored in the water storage panel 5 and the solar irrigation pump 14 is used. Can be pumped up and reused automatically. The electric power of the irrigation pump 14 is generated by the solar panel 15 as described above, and when the stored water is insufficient, the water level is replenished by the water level sensor.

  Since the rooftop greening system of the present embodiment is configured as described above, by disposing a plant having a transpiration effect and a portion corresponding to a large shade, the concrete of the concrete, which is a major problem in the heat island phenomenon, is provided. Does not store heat. In addition, the wind that has been chilled during the night is taken into the enclosed space, which is a large cavity, and a comfortable state is obtained in the morning of the next day. From the day of the day, the wind flows in the enclosed space, and a cool wind due to the so-called water-damping effect is sent to the surroundings.

  This operation will be described with reference to FIGS. 5 and 6, an enclosed space is provided between the installation surface 23 on which a large number of planting units as described above are installed and the container portion 1 installed on the installation surface 23 via the support legs 2. A state in which the portion 24 is formed and a state in which a louver 25 for opening and closing the surrounding space portion 24 is provided on one end side thereof are schematically illustrated.

  For example, an image of the morning in the summer will be described with reference to FIG. 5. When the louver 25 is closed and the enclosure space 24 is closed, cold air is taken into the enclosure space 24 at night, It will be in a state where you can spend the morning comfortably.

  Further, the summer afternoon image will be described with reference to FIG. 6. When the louver 25 is opened to open the enclosure space 24, warm air flows into the enclosure space 24 through the louver 25, and Although the temperature in the surrounding space part 24 rises, the wind which became warm is discharged | emitted and the temperature in the surrounding space part 24 falls gradually by transpiration of the plant planted by the planting unit. Further, the wind is taken into the surrounding space portion 24 through the louver 25, and the wind that has been cooled by the evaporation of water due to the transpiration of the plant is also discharged, and there is a space as if in the shade in the surrounding space portion 24. Will be formed.

  In this way, in summer, by forming a portion corresponding to a large shade and cooling the building, the air conditioning load on the downstairs is reduced.

  On the other hand, in winter, as shown in FIG. 7, when the louver 25 is closed and the surrounding space portion 24 is closed, cold air is taken into the surrounding space portion 24 and becomes “still air”. The enclosed space 24 in a “still air” state provides a heat insulating effect that has not been obtained in the past.

  When the operation described based on FIGS. 5 to 7 as described above is further described based on FIG. 8 from another viewpoint, the warm air flowing into the enclosed space 24 is the water stored in the water storage panel 5. The evapotranspiration and a tree-like atmosphere formed in the surrounding space portion 24 cause a cold wind to be discharged. Due to the heat exchange action and the transpiration action of the plant planted in the planting unit, the heat of vaporization is released from the enclosed space 24 in the system to the outside as a whole.

  On the other hand, in a plant planted in the planting unit as described above, photosynthesis is performed by sunlight, and carbon is fixed. This also alleviates so-called warming.

  As described with reference to FIG. 8, the roof greening system of the present invention provides a system such as a “floating floor” that creates a forest-like environment as a whole. In other words, the three-dimensional green space environment formation mechanism that can express seasonal expressions richly will alleviate the heat island phenomenon. In addition, the forest space of the forest can artificially form a phenomenon similar to a natural phenomenon that creates a cool environment in summer and a warm environment in winter.

In this way, a system that enables compact circulation of photosynthesis, thermal environment, water environment, etc. can be formed on the roof of the building, and the effectiveness of floating floors in warm and humid environments can be further improved. A warming environment mitigation system can be formed.

  Furthermore, it can be said that such a rooftop greening system is a system that creates an environment like a mountain as shown in FIG. That is, since the container part 1 which planted the plant is arrange | positioned at the upper part of many planting units, the system of a rooftop greening will be in the state concealed by this plant, and many planting units The height is adjusted by the number of the support legs 2 and so on, so that a large number of planting units with different heights are arranged, so that it produces a rich terrain like a mountain as a whole. A landscape will be obtained.

  In addition, the water circulation system using the irrigation pump 14 and the solar panel 15 as described above can be used to create a water circulation system that approximates the penetration, storage, and evapotranspiration of rainwater and water spray in nature such as mountains. It can be realized in a compact area called a part. As a result, it is possible to provide a three-dimensional greening system that was difficult to realize with conventional thin-layer greening as a system that is applied to urban thermal environment countermeasures.
