Description

  The present invention relates to a greening system that takes measures against the heat island phenomenon by installing plants.

  The urban heat island phenomenon is becoming more and more severe. As measures against the heat island phenomenon, there is known a method based on rooftop greening, and there are documents disclosed regarding the rooftop greening (see, for example, Patent Documents 1 and 2).

  In patent document 1, the roots of a perennial greening plant (vine plant) are planted in a planting bed formed in a container, and the leaf part and the vine part are entangled and cultivated on a cultivation shelf provided above the planting bed. Is disclosed. Moreover, it is set as the structure by which a watering pipe is embed | buried in a planting bed and water etc. are supplied to a culture medium from this watering pipe.

  Patent Document 2 discloses a configuration in which plants are propagated on a lattice-like support member made of a frame material. Then, by installing a tube body containing the root holding material inside the frame material, and sowing the plant seeds on the root holding material to allow the plant to grow, the roof is covered with almost the entire surface of the support member. It is supposed to be green.

  In the techniques disclosed in Patent Documents 1 and 2 described above, the roof surface due to greening of the roof is shielded from light, and the temperature rise of the roof surface (concrete surface) is suppressed. As a result, the effect of reducing power consumption for cooling is expected only for buildings such as buildings with green roofs, that is, only for the buildings.

JP-A-6-197649 JP 2006-20542 A

  However, in an environment where global warming is accelerating, in view of the heat island phenomenon of the entire city, it is not sufficient as a countermeasure to perform greening of rooftops individually for each building as in the past. It can not cope with the speed of.

  In addition, it is possible to reduce greenhouse gas emissions by reducing power consumption for cooling by greening. However, as can be seen from the status of the Kyoto Protocol, further greenhouse gas emissions There is a need to reduce emissions, and it is necessary to plan greening with a view to wide-ranging development in the entire city.

  Taking this situation into consideration, focusing on the conventional greening technology, it is based on the simple idea of simply greening the rooftop and covering the rooftop surface with plants. However, only for buildings with rooftop greening, the power consumption for cooling can be reduced.

  However, especially on the rooftop of a city, it is easy to blow the building wind in relation to other buildings, and it is easy to blow air from the sea close to the city. It is considered that when air passes through the green roof, the effect of cooling the air is obtained. That is, it is an idea that the cooling effect by the air can be obtained by cooling the air flowing through the city or suppressing the temperature rise by the greening of the roof.

  However, in the conventional greening forms such as Patent Document 1 and Patent Document 2, since the idea is simply to shield the rooftop with plants, the air is cooled without the idea of cooling the air flowing through the city. In that respect, a sufficient effect cannot be expected.

  Also, when considering the development of greening in a wide area of the city, consider the ease of installation in existing buildings, the ease of repairing buildings, and the ease of removal (recovery and recycling) when rebuilding. There is a need.

  Moreover, in the idea of growing a plant after installation of a greening facility, it takes a growing time, and it takes a long time until the effect of greening comes out. In such a situation, it becomes impossible to cope with the accelerating global warming.

  In addition, when the plant has withered, or conversely, when the plant has grown too much, maintenance such as removal (collection) and pruning is necessary, but this maintainability needs to be considered.

  Therefore, in view of the above problems, the present invention proposes a novel tree planting unit and a tree planting system that effectively suppresses the heat island phenomenon in an urban space and has excellent maintainability.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, as described in claim 1,

Moreover, as described in claim 3,
The mist is discharged into the space according to the temperature inside the space or according to the outside temperature.

Moreover, as described in claim 4,
The release of mist into the space is configured to be performed according to the strength of the wind speed of the air flowing inside the space, or according to the strength of the wind speed of the air flowing outside,
When the wind speed is 0 m / s or more and less than 5.5 m / s, 0 m / s or more and 1.6 m / s, or 0 m / s or more and less than 0.3, the mist is discharged. is there.

Moreover, as described in claim 5,
The inside of the greening tree unit and / or the outside is configured to be irradiated with light by an illumination device.

Moreover, as described in claim 6,
A plurality of greening tree units according to any one of claims 1 to 5 are installed, and a greening system in which air is cooled by each greening tree unit.

  The effects of the present invention are as follows.

That is, in the device according to claim 1,
This greening tree unit efficiently cools the air flowing through the city space, so that it is possible to blow the cooled air over a wide area of the city space, thereby reducing the temperature of the entire city space. It becomes possible. Further, since not only air cooling but also greening (if it is a rooftop, rooftop greening) can be performed, a greening tree unit having two functions can be realized.

In the device according to claim 2,
By adopting a configuration to carry in and assemble greening panels with plants grown in factories and farmland, rooftop greening and cooling air can be blown immediately after construction, and immediate warming measures can be taken. It becomes possible. In addition, maintenance can be easily performed when a plant has withered, when a greening panel or the like is changed to change the type of plant, or when a greening tree unit is removed (collected).

In the device according to claim 3,
For example, when the temperature is low such as in autumn or winter, the heat island phenomenon does not occur. Therefore, waste of water (mist) can be suppressed by stopping the release of fog in such a situation. When the temperature change during the daytime and nighttime is intense during the period before and after summer, water (fog) can be effectively consumed only during the time when the temperature is high and cooling is effective.

In the device according to claim 4,

When the wind speed is low, it is assumed that the air is stagnating in a wide area of the urban space and the heat island phenomenon is aggravated. The effect of lowering the temperature can be expected. In addition, the effect of generating a new air flow (wind (air convection)) can be expected due to a decrease in temperature in the region (the area of the building where the tree planting unit is installed on the roof). The air temperature can be expected to promote a decrease in the temperature of the entire city.

In the device according to claim 5,
Illumination of the tree planting unit can be performed at night. In particular, when the mist is released, a fantastic illumination can be realized at night.

The figure explaining the illumination by an illuminating device. The figure shown about the example of a dome shape greening tree unit.

Next, an embodiment of the invention will be described.
FIG. 1 shows a configuration of a tree planting unit 1 according to an embodiment of the present invention.
As shown in FIG. 2, the tree planting unit 1 includes a cubic solid frame 2, greening panels 3 and 3 attached to the solid frame 2 so as to cover the four sides of the solid frame 2, 2 and a greening panel 4 attached to the three-dimensional frame 2 so as to cover the upper part of 2.

  Moreover, as shown in FIG. 2, the three-dimensional frame 2 is comprised by the cube frame shape by processing and assembling steel materials.

  Moreover, as shown in FIG. 2, each greening panel 3 which covers the side part of the three-dimensional frame 2 forms a four-sided frame by processing and assembling steel materials, and heat-treated wood having long-term weather resistance in the four-sided frame. It is set as the structure by which the grating | lattice formed is arrange | positioned. In addition, the plant 5 is propagated so as to be entangled with the lattice, and the lattice is covered with the plant 5, so that a so-called wall surface by the plant 5 is formed. In addition, a plant box 6 in which a medium substance is placed is provided at the lower part of the greening panel 3, and a plant 5 is planted in the medium substance.

  As shown in FIG. 2, the plant 5 is preferably an evergreen climbing plant such as Hedera. By setting it as a climbing plant in this way, the greening panel 3 is not completely covered with the plant 5, and air can pass through the gap between the plants 5. Moreover, by setting it as a vine plant, the increase in the weight by the growth of the plant 5 becomes a small thing, and the increase in the load of the rooftop floor surface 11 by the increase in the weight of the tree planting tree unit 1 comes to be suppressed. Moreover, when the lattice of the greening panel 3 is formed of heat-treated wood, the entanglement of the plant becomes good. In addition, the tree planting unit 1 functions as a so-called tree substitute. Compared with the conventional tree planting by the tree relocation, the relocation cost is large and the raw material of the tree is degraded. The problem can be reduced.

  Moreover, as shown in FIG. 2, the greening panel 4 which covers the upper part of the three-dimensional frame 2 forms a four-sided frame by processing and assembling steel materials in the same manner as the side-side greening panel 3, and heat-treated wood in the four-sided frame. In this configuration, a lattice made of the above is formed. Further, the plant 5 is propagated so as to be entangled with the lattice, and the lattice is covered with the plant 5, so that a so-called wall surface by the plant 5 is configured. Further, a plant box 7 in which a medium substance is placed is provided on the lower surface side of the greening panel 4, and a plant 5 is planted in the medium substance.

  As shown in FIG. 1, a space 8 surrounded by the greening panels 3 and 4 is formed by assembling the greening panels 3 and 4 to the three-dimensional frame 2. And what attached greening panels 3 and 4 to this solid frame 2 is made into the greening tree unit 1, and this greening tree unit 1 is mounted in the installation base 10. FIG. In addition, the lower part of the space 8 of the greening tree unit 1 is opened without attaching a greening panel to a portion constituting the lower surface of the greening tree unit 1.

  As shown in FIG. 2 and FIG. 3, the installation base 10 is configured by installing floor bundle members 12, 12 on the rooftop floor surface 11, and overdrawing members 13, 13 laid on the floor bundle members 12, 12. The three-dimensional frame 2 is placed and fixed on the large pulling members 13 and 13. In addition to this configuration, for example, the installation foundation 10 has a length of the floor bundles 12 and 12 as columns, and a height of about 1 m to about 3 m (which may be higher) from the rooftop floor surface 11. It is good also as the space where a person can pass under the tree planting tree unit 1 is formed by installing the large pulling materials 13 and 13 as a beam at the position of.

  In addition, as shown in FIG. 3, in the place where the greening tree unit 1 is not placed between the greening tree units 1. The greening panel 4 is placed. Thereby, the wide range of the rooftop floor surface 11 is covered with the greening tree unit 1 or the greening panel 4. In addition, by installing the tree-planting tree units 1 and 1 at intervals, air passages can be secured between the tree-planting tree units 1 and 1, and air is supplied to the tree-planting tree units 1 and 1. A wide area (surface area) can be secured. In addition, it is good also as a structure by which all the rooftop floor surfaces 11 are covered with the greening tree unit 1.1 by providing the greening tree unit 1.1 in a row.

  Moreover, as shown in FIG. 3, the greening tree unit 1 and the greening panel 4 are connected and fixed to the installation foundation 10 by a fixing tool such as a bolt (not shown), and the connection and fixing by the fixing tool is released. According to the above, the greening tree unit 1 and the greening panel 4 can be removed from the installation base 10 again and replaced with other greening tree units 1 and the greening panel 4. Thereby, when the plant 5 has withered, when changing the greening panel 3 or the like to change the type of the plant 5, or when removing (recovering) the greening tree unit 1, maintenance is easily performed. Can be done. Also, instead of installing the greening panels 3 and 4 in the tree planting tree unit 1, advertising can be done by installing an advertising board or by installing an advertising board in a part of the area of the greening panel 3 or 4 Also good. Moreover, it is also possible to form a specific pattern by arranging the greening tree unit 1 and the greening panel 4 using the color of the plant.

  Moreover, as shown in FIG.1 and FIG.2, the water supply pipe | tube 21 is piped so that it may pass between the floor bundle materials 12 * 12 of the installation foundation 10. As shown in FIG. A water spray pipe 22 is branched upward from the water supply pipe 21, and a spray nozzle 23 is arranged at the upper end of the water spray pipe 22. As shown in FIG. 1, the spray nozzle 23 generates a mist 24 (water particles are made into a mist). Further, the mist 24 is sprayed in the form of a mist (mist) over a wide area in the space 8 by setting the nozzle diameter of the spray nozzle 23. In addition to this embodiment, the greening panels 3 and 4 may be provided with a water distribution pipe that communicates with the water supply pipe 21 and a watering nozzle, and the spray may be sprayed from the watering nozzle. Further, the state of the mist discharged into the space 8 is a mist 24 (average particle diameter of about 10 μm) that is easy to evaporate, or a water droplet that is larger in size than the mist 24 (for example, an average particle diameter of 0. 1 mm to 1 mm).

  Then, as shown in FIG. 1, a mist drifts in the space 8, and the mist evaporates (vaporizes) so that heat is absorbed (absorption of vaporized heat), and the temperature in the space 8 can be lowered. The air present in the space 8 is cooled. Then, the air 30 </ b> A blown into the tree planting unit 1 that forms such a cooled space 8 is sent out as air 30 </ b> B after being cooled in the space 8.

  In this way, as shown in FIG. 1, the air 30A is cooled by the tree planting tree unit 1, so that the air passing through the roof can be cooled as a whole. Moreover, by forming the space 8 surrounded by the greening panels 3 and 4, the space 8 can be filled with the mist 24, and the space 8 can be reliably cooled. Thus, the air 30A blown into the tree planting unit 1 can be reliably cooled, and the cooling efficiency of each tree planting unit 1 can be improved. Moreover, in the above tree planting tree unit 1, the effect | action of the radiator which performs heat exchange about the blown-in air is exhibited, and the effect | action of this radiator is performed efficiently.

  Moreover, the spray of the mist 24 shown in FIG. 1 is good also as a structure implemented according to the temperature level. That is, for example, a temperature sensor (not shown) is installed outside or inside the tree planting unit 1 and an electric valve is installed in a piping system such as the water supply pipe 21 or the water spray pipe 22, and the electric valve is temperature-controlled. It opens and closes according to the measured value of the outside air temperature by the sensor. Alternatively, the pump device that supplies water to the water supply pipe 21 is driven / stopped according to the measured value of the outside air temperature by the temperature sensor. According to this, for example, when the temperature is 28 ° C. or higher, the air 30A is positively cooled by spraying the mist 24, while when the temperature is less than 28 ° C., the mist 24 is not sprayed and water is discharged. Automatic control such as refraining from use can be performed. For example, when the temperature is low, such as autumn or winter, the heat island phenomenon does not occur, and therefore, waste of water (mist) can be suppressed by stopping the spraying of the mist 24 in such a situation. Further, when the temperature change during the daytime and nighttime is severe in the period before and after summer, water (fog) can be consumed effectively only during the time when the temperature is high and cooling is effective.

  Moreover, the spray of the mist 24 shown in FIG. 1 is good also as a structure implemented according to the strength of the wind speed of the air which flows through the greening tree unit 1. FIG. That is, for example, a wind speed sensor (not shown) is installed outside or inside the tree planting tree unit 1, and an electric valve is installed in a piping system such as the water supply pipe 21 or the water sprinkling pipe 22. It opens and closes according to the measured value of the wind speed by the sensor. Alternatively, the pump device that supplies water to the water supply pipe 21 is driven / stopped according to the measured value of the wind speed by the wind speed sensor. According to this, for example, when the wind speed is less than 5.5 m / s, the air 30A is actively cooled by the spray of the mist 24, while when the wind speed is 5.5 m / s or more, the spray of the mist 24 is sprayed. It is possible to perform automatic control such as refraining from using water without using it. This automatic control is realized by a well-known configuration such as a well-known wind speed sensor and a control device that outputs a signal for opening / closing the electric valve (or driving / stopping the pump) in accordance with the detection value of the wind speed sensor. can do. Further, the wind speed sensor and the control device can be installed on the greening panels 3 and 4 and the installation foundation 10.

  When the wind speed is particularly low (for example, 0 m / s or more and less than 5.5 m / s, preferably 0 m / s or more and less than 1.6 m / s, more preferably 0 m / s or more and less than 0.3). In some cases, it is assumed that the air is stagnating without moving in a wide area of the city space, and the heat island phenomenon is likely to deteriorate. Therefore, by cooling with fog when the wind speed is low, The effect of lowering the temperature can be expected. In addition, the effect of generating a new air flow (wind (air convection)) can be expected due to a decrease in temperature in the region (the area of the building where the tree planting unit is installed on the roof). The air temperature can be expected to promote a decrease in the temperature of the entire city.

  Regarding wind speed standards, the wind power 0 to 3 in the Japan Meteorological Agency wind class table (refer to: http://www.jma.go.jp/jma/kisho/know/yougo_hp/kaze.html#E10) if necessary. It is preferable to set it, assuming that the wind power (wind speed) is closer to 0, and the effect on the heat island phenomenon according to the present invention is more remarkable. In addition, the water for generating the mist 24 may be tap water, but it is considered preferable to use rain water or middle water from the viewpoint of water cost.

  Furthermore, it is good also as implementing spraying of the fog 24 shown in FIG. 1 according to both high and low air temperature, and the wind speed of the air which flows through the greening tree unit 1. FIG. That is, the spraying of the mist 24 is controlled based on the measured values of both the temperature sensor and the wind speed sensor.

  As shown in FIGS. 4 and 5, a plurality of tree planting tree units 1 configured as described above are installed to form a tree planting system 40/40, which is installed on the roof of the building 50/50. In addition to the greening of the roof, the green tree units 1 and 1 can cool the air 30A passing through the buildings 50 and 50 and blow the cooled air 30B.

  In addition, as shown in FIG. 2, the tree planting unit 1 and the installation foundation 10 can be constructed by assembling each part, so that construction on the site is easy and construction on the roof of an existing building is also easy. It is. Such good workability makes it easy to construct new buildings and rooftops of existing buildings, making it possible to realize extensive rooftop greening in urban spaces. is there. And according to the tree planting tree unit 1 (greening system 40) according to the present invention, as shown in FIGS. 1, 4, and 5, the air 30A is efficiently cooled, so the air 30B cooled in a wide area of the urban space. It becomes possible to aim at the temperature fall as the whole city space.

  Also, as shown in FIGS. 4 and 5, since it can be deployed in a wide range in an urban space, mass production and distribution of parts constituting the tree planting tree unit 1 can be promoted, and cost reduction can be achieved. Can do. Moreover, as shown in FIG. 2, by constructing the tree planting unit 1 as an assembly type, construction can be carried out by bringing in and assembling the planting panels 3 and 4 in which plants 5 are prosperous in the factory or farmland. Later, rooftop greening and cooling air can be blown immediately, and it becomes possible to take immediate measures against global warming.

  Further, as shown in FIG. 6, lighting devices 35 and 35 for irradiating light 34 (for example, light using low-voltage LEDs) at night are arranged in the space 8 inside the tree planting unit 1. Thus, the light 34 may be used to illuminate the space 8 and the surrounding area of the tree planting unit 1. According to this, illumination of the greening tree unit 1 at night can be performed. Moreover, in this illumination, since the light 34 leaks from the clearance gap between the plants 5, the light 34 leaking from the greening tree unit 1 will be interrupted | blocked moderately, and a soft impression can be given. At the same time, if the mist 24 (see FIG. 1) is sprayed, the light 34 is diffused by the mist 24 (see FIG. 1), so that a fantastic illumination can be realized. Further, the illumination devices 35 and 35 may be provided outside the greening tree unit 1 in addition to being provided in the space 8. For example, there is a configuration in which a stay extending upward is provided on the greening panel 4 and light is irradiated downward from the upper portion of the stay.

  Moreover, the illuminating devices 35 and 35 shown in FIG. 6 can be installed in any one of the three-dimensional frame 2, the greening panels 3 and 4, the installation base 10, the water supply pipe 21, the water spray pipe 22 and the like shown in FIG. Moreover, as a power source for the illumination devices 35 and 35, a general power source such as a primary battery or a commercial power source may be used, or solar radiation may be used by combining solar power generation and a storage battery. In particular, when the tree planting unit 1 is installed on the rooftop, the tree planting unit 1 is installed in an environment that facilitates daylighting. It is possible to generate power efficiently. Alternatively, the illumination sensor may automatically turn on only at night. Various light sources such as incandescent lamps and low voltage LEDs can be used as the light source. Moreover, the illumination devices 36 and 36 may be provided outside the greening panel 4 (or the greening panel 3), and illumination by the illumination devices 36 and 36 may be performed.

As described above, the present invention can be implemented.
That is, as shown in FIG. 1 and FIG. 2, a greening tree unit 1 in which a space 8 surrounded by greening panels 3 and 4 on which plants 5 are grown is formed, and is discharged from the spray nozzle 23 into the space 8. The mist 24 is used to cool the air in the space 8 to the greening tree unit 1.

  The greening tree unit 1 efficiently cools the air 30A flowing through the city space, so that the air 30B cooled in a wide area of the city space can be blown, and the temperature of the city space as a whole can be reduced. It becomes possible to plan. Moreover, since not only the cooling of the air 30A but also greening (if it is a rooftop, rooftop greening) can be performed, the greening tree unit 1 having two functions can be realized.

  Moreover, as shown in FIG.1 and FIG.2, the greening panel 3 * 4 which comprises the greening tree unit 1 is with respect to the fixing member (three-dimensional frame 2 or the installation foundation 10) to which the greening panel 3 * 4 is fixed. It shall be configured to be detachable.

  As a result, by adopting a configuration for carrying in and assembling the greening panels 3 and 4 in which plants 5 are prosperous in factories and farmland, rooftop greening and cooling air can be blown immediately after construction. It is possible to take measures against global warming. In addition, when the plant 5 has withered, when the greening panel 3 is changed to change the type of the plant 5, or when the greening tree unit 1 is removed (collected), maintenance can be easily performed. it can.

  Further, as shown in FIG. 1, the mist 24 may be released into the space 8 according to the temperature inside the space 8 or according to the outside temperature.

  As a result, for example, when the temperature is low such as autumn or winter, the heat island phenomenon does not occur. Therefore, the waste of water (mist) is suppressed by stopping the spraying of the mist 24 in such a situation. In addition, when the temperature change during the day and night is severe in the period before and after summer, water (mist) can be effectively consumed only during the time when the temperature is high and cooling is effective. .

  Moreover, as shown in FIG. 1, the release of the mist 24 into the space 8 is performed according to the strength of the wind speed of the air 30A flowing inside the space 8 or the strength of the wind speed of the air 30A flowing outside. Also good.

  Thereby, particularly when the wind speed is weak (for example, 0 m / s or more and less than 5.5 m / s, preferably 0 m / s or more and less than 1.6 m / s, more preferably 0 m / s or more and less than 0.3). When the wind speed is low), it is assumed that the air stays in the wide area of the urban space without moving, and the heat island phenomenon may be worsened. The effect of lowering the temperature of the entire city can be expected. In addition, the effect of generating a new air flow (wind (air convection)) can be expected due to a decrease in temperature in the region (the area of the building where the tree planting unit is installed on the roof). The air temperature can be expected to promote a decrease in the temperature of the entire city.

  Moreover, as shown in FIG. 6, it is good also as a structure by which the irradiation of light by the illuminating device 35 * 35 is performed about the inside of the tree planting tree unit 1 and / or the outside.

  Thereby, it becomes possible to implement illumination of the tree planting tree unit 1 at night. In particular, when the mist is released, a fantastic illumination can be realized at night.

  Further, as shown in FIGS. 3 to 5, a plurality of greening tree units 1 are installed, and greening systems 40 and 40 in which air is cooled by each greening tree unit 1 are provided.

  As a result, as shown in FIG. 4 and FIG. 5, greening and air cooling can be performed at each location (building 50/50) where the greening system 40 is installed, and the greening system 40 is expanded over a wide area of the urban space. By doing so, it becomes possible to aim at the temperature fall as the whole city space.

  Further, in the configuration example shown in FIGS. 1 and 2, the cube-shaped tree planting unit 1 is used. However, as shown in FIG. 7, a dome-shaped tree planting unit 70 that forms an arch-shaped cross section may be used. . In this case, it is desirable that the dome shape is configured by assembling a plurality of greening panels 71 and 71, and each greening panel 71 and 71 is configured to be detachable.

  The greening tree unit of the present invention can be deployed without being limited to the installation location, such as being installed on the rooftop and used for rooftop greening, or arranged side by side to configure a street.
