A narrow flange portion 15a is formed on the outer peripheral edge of the opening of the tray 15, and the flange portion 15a reinforces the entire tray 15 so that the tray 15 can be used as a handle portion when the tray 15 is transported. There is. A large number of drain holes 15b are formed on the bottom wall of the tray 15, and water such as rainwater is discharged through these drain holes 15b. The root-preventing sheet 16 is a sheet having good water permeability, and is made of, for example, a non-woven fabric of polyester fiber, and has penetration resistance to roots of plants and invasion resistance to soil. The net body 17 is configured by entwining long fibers such as polyester at a low density,
It is slightly lower than the height of the tray 15
Hold eight. In addition, this net 17 is a root-proof sheet 16
On the other hand, it may be spot-bonded at a plurality of suitable places, or may be fastened using clips at suitable places.

As shown in FIG. 3, the soil 18 is mainly composed of aggregated soil 18a and coarse aggregate 18b, on which adjustment soil 18c, improved soil 18d, organic fertilizer 18e and binder 1 are provided.
It is configured by mixing an appropriate amount of 8f. These mixing ratios are, for example, 57.5% for aggregated soil 18a, 30% for coarse aggregate 18b, 2.5% for adjusting soil 18c, 2.5% for improved soil 18d, and 2.5% for organic fertilizer. 18e is set to 2.5% and the binder 18f is set to 5%. In addition,
The mixing ratio of the soil 18 can be arbitrarily changed and set according to the type of the planting 13, but the following mixing ratio is preferable. That is, the aggregated soil 18a is 70 to 40%, the coarse aggregate 18b is 50 to 20%, and the adjusting soil 18c is 5-1.
5%, improved soil 18d is 5 to 1.5%, organic fertilizer 18e is 5 to 1.0%, and binder 18f is 6 to 3%.

The aggregated soil 18a in the paddy soil 18 is as follows.
Akatama soil, Kanuma soil, etc. having a particle size of 10 to 15 mm are used.
As the coarse aggregate 18b, burned rock having a particle size of 10 to 25 mm, that is, crushed lava, gravel, porous concrete, or the like is used. As described above, since the aggregated soil 18a and the coarse aggregate 18b having a large grain size are used, many voids exist between the aggregated soil 18a and the coarse aggregate 18b, and the air permeability of the soil 18 is increased. Therefore, the water permeability is secured, the growth of new roots of the planted plant 13 is promoted, and the metabolism is promoted. Further, as coarse aggregate, crushed lava having a pH of 7 to 9 is used, and the soil 18 as a whole is adjusted to have an alkaline pH of 7 or more. Therefore, this soil 1

Then, as shown in FIG. 4, by using the multistage cultivation shelf 19, the planting base material 14 on which the planting material 13 is vegetated is placed on the shelf plate 19a of the multistage cultivation shelf 19, and the planting material is planted. 13 is cultivated and aged in a predetermined overgrowth state, for example, the roots of the planting plant 13 are rooted in the soil 18 and covered with the planting plant 13 until the coverage is about 70%.

In this case, as the planting product 13, a perennial plant, for example, a sedum such as Mexican mannunca is used. Further, a plurality of kinds of perennials may be combined, and for example, Mexican gems may be mainly used, and legumes and herbs may be appropriately combined. As the planting plant 13, European Mannen, Kossinium, Sakasa Mannen, Ginseng, Tight Gome, Morimura Mannengsa, Malba Mannengsa, and the like are suitable as the planting 13 in addition to Mexican Mannengsa. Furthermore, as the legumes, clover, white clover, as herbs, mint,
Lavender is suitable, and succulent aloe, cactus, etc. can be used as the planting 13.

When the planting product 13 is grown, the roots of the plant 13 grow roots so as to crawl in the voids of the cultivating soil 18, and are entwined with each other in the voids to be attached to the cultivating soil 18. In this state, since air permeability and water permeability are secured for the roots of the planting plant 13, water and nutrients for the roots are appropriately deficient, and the planting plant 13 does not grow too long. Cranes grow to spread evenly without mottled.

When the planting material 13 is cultivated, since the planting base material 14 is constructed by accommodating the soil 18 in the hard tray 15 made of synthetic resin, the planting base material 14 has a stable shape. It can be easily handled in the state of being. In addition, a large number of planting base materials 14 are provided on the multi-tiered cultivation shelves 19 as described above.
Since it can be cultivated and cured while being placed on the shelf plate 19a, it can be easily cultivated and cured without requiring a large field.

Next, a method for constructing a rooftop greening system using the planting base material 14 as described above will be described. By the way, at the time of this construction, the planting base material 14 obtained by cultivating and growing the planting 13 up to a predetermined overgrowth state is transported from the cultivation location to the construction location on the roof of the building 11. In this case also, the planting base material 14 is a hard tray 15 made of synthetic resin.
The planting base 1

Can be fixed in the installed state.

As described above, when a plurality of planting bases 14 formed by planting the planting 13 are laid on the floor 12 of the roof,
Since the planting base material 14 is composed of the hard tray 15, it is possible to lay the planting base material 14 easily and surely without displacement even if the floor surface 12 on the roof is an inclined surface. You can Moreover, since each planting base material 14 is laid by the support tool 20 at a predetermined distance from the floor surface 12 of the roof, it is possible to always maintain the drainage property and the air permeability of the soil 18 of the planted product 13. As a result, the planted product 13 can be properly grown.

The structures of the supporting member 20 and the fixing member 22 will be described. As shown in FIGS. 7 and 8, the support tool 20 is integrally formed of a hard synthetic resin, and has a disk-shaped substrate portion 24 and a central boss portion 25 provided upright at the center of the upper surface of the substrate portion 24. The central boss portion 25 is integrally provided with a restricting wall portion 26 having a planar cross shape and protruding from the outer periphery of the central boss portion 25.
Four support boss portions 27 as support portions are provided on the substrate portion 24 so as to protrude between the regulation wall portions 26. And
The corner portion of the tray 15 of the planting base material 14 is supported by the support boss portion 27 in a state of being floated from the floor surface 12 of the roof, and the corner portion is brought into contact with the adjacent regulation wall portion 26 to be predetermined. It is designed to be positioned.

A bolt screw hole 3 is formed at the center of the central boss portion 25.

The center of the cross 1 is located outside the central boss portion 25. So as to correspond to the breaking groove portion 31,
The breaking groove 32 is also formed to extend in the vertical direction on the side surfaces of the regulation wall portions 26 adjacent to each other. Then, when the support tool 20 is arranged and fixed to the end of the floor 12 on the rooftop, unnecessary portions of the support tool 20 can be broken off and removed from these breakage grooves 31 and 32 as needed. It has become.

As shown in FIGS. 7 and 9, the fixture 2
2 is integrally formed of a hard synthetic resin, and is composed of a rectangular flat plate-shaped substrate portion 33 and four projecting portions 34 protruding from four corners of the lower surface of the substrate portion 33. A bolt insertion hole 35 is formed in the board portion 33, and the bolt 2 is inserted into the bolt screw hole 30 of the support tool 20 through the bolt insertion hole 35.

On the upper surface of the substrate portion 33, a thin-walled breaking groove portion 36 is formed so as to extend in a plane cross shape. Like the breaking groove 32, the breaking groove 36 is also off the center of the substrate portion 33. Then, in a state where the fixing tool 22 is fixed on the supporting tool 20 by the bolts 23, unnecessary portions of the fixing tool 22 projecting above the corner portion of the tray 15 of the planting base material 14 can be broken off as needed. The groove 36 can be broken and removed.

If the supporting tool 20 and the fixing tool 22 are broken in the breaking grooves 32 and 36, respectively, the supporting tool 20 and the fixing tool 22 can be installed without interfering with the rooftop wall or the like. That is, as is apparent from FIGS. 11 and 12, by breaking the support tool 20 and the fixing tool 22 through the breaking grooves 32 and 36, the following modes can be adopted. That is, the first, second, third

Next, in the rooftop greening system as described above, a sprinkler for spraying water on the planting material 13 on the planting base material 14 laid on the rooftop of the building 11 and its control structure will be described. .

As shown in FIG. 1, a sprinkler 40 is arranged at an appropriate position on the roof of the building 11, and the sprinkler 40 operates to plant the plant 13 on the planting base 14.
Water is supposed to be sprayed on. In addition, a solar cell 41 as shown in FIG. 10 is installed at another place on the roof,
The electric power obtained by the solar cell 41 is stored in the battery 42 and used for operating the sprinkler 40.

As shown in FIG. 10, the sprinkler 4 is
A memory 44 is connected to the control device 43 for controlling 0, and data relating to the operation timing of the sprinkler 40 corresponding to the sunshine duration is stored in the memory 44. The solar cell 41 is connected to the control device 43, and the sunshine signal detected by the solar cell 41 is output to the control device 43. Then, the control device 43 causes the sunshine duration counter 45 to integrate the sunshine signal data. Furthermore, a rainfall sensor 47 is connected to the control device 43, and by this rainfall sensor 47,
Rainfall is detected. When rainfall is detected by the rainfall sensor 47, the sunshine duration data accumulated by the sunshine counter 45 is cleared.

A sunshine duration counter 45 and an opening / closing valve 46 for the sprinkler 40 are connected to the control device 43. Then, when the sunshine duration counted by the sunshine duration counter 45 reaches a predetermined value stored in the memory 44, the control device 43 opens the opening / closing valve 46 to supply water from the sprinkler 40 to the planting plant 13. It is designed to be sprayed for a predetermined time.

Therefore, in the rooftop greening system equipped with this sprinkler 40, water can be sprayed to the plantings 13 automatically according to the sunshine time, and the plant 13 can be easily maintained and managed. Become.

Therefore, according to this embodiment, the following effects can be obtained. In this planting base material 14, a flat soil tray 15 made of a synthetic resin contains and arranges a soil 18 for planting a planting material 13 such as Mexican mannosa. Therefore, unlike the prior art, as is clear from FIG. 4 described above, it is possible to efficiently cultivate in a narrow space without requiring a large field. Since the tray 15 has excellent shape stability, the tray 15 can be transported in a stacked state and easily laid during construction. Therefore, the construction cost can be reduced. In addition, since the tray 15 has excellent shape stability, the tray 15 can be laid on a slope. In addition, as the tray 15, the tray used for the seedling raising container can be reused, and by doing so, the construction cost can be further reduced.

・ The soil 18 is aggregated soil 18a and coarse aggregate 1
Since it is mainly composed of 8b, many voids are formed in the soil 18. Moreover, scattered soil or the like adheres to the surfaces of the aggregated soil 18a and the coarse aggregate 18b, and the aggregated soil 18a and the coarse aggregate 18b are repeatedly dried and wetted by rainwater or the like to form the aggregated soil 18
It clings to the surface of a and the coarse aggregate 18b, and is cultivated. The air gap and the water permeability are improved by the voids. For this reason, the planted plant is not overgrown, and the plant is crawlingly proliferated and spreads over a wide area, and weeds are less likely to grow, and a good appearance can be obtained. Also,
Since the planting 13 is crawling and growing, maintenance such as pruning is unnecessary, and maintenance and management costs can be reduced. Then, since the roots of the planting plants repeatedly start rooting in the voids, the alternation of generations can be continued and the planted state of the planted plants can be maintained for a long period of time. Furthermore, since many voids are formed in the soil 18, the planting base material 14 is light in weight and easy to handle in transportation and the like.

The coarse aggregate 18b is composed of at least one type of crushed lava, gravel, and porous concrete. When lava crushed stone is used, it can contribute to making the soil alkaline, cost can be reduced when gravel is used, and when porous concrete is used, it can be made alkaline and lightweight. It will be possible. Since the soil 18 is alkaline, weeds can be prevented from growing, and a good appearance can be maintained for a long period of time. Further, when porous concrete is used, the surface area of the coarse aggregate 18b can be substantially expanded, and the condition for growing the planting 13 can be improved.

In this planting base material 14, the soil 18 is mixed with a binder that exerts a binding force by moisture. Therefore, the cultivating soil 18 can be preliminarily solidified in a state where the cultivating soil 18 is accommodated on the tray 15, and the tray 15 is slanted when the planting product 13 is cultivated, cured, transported, or laid on a rooftop. Even if it becomes, it is possible to reliably prevent the soil 18 from spilling from the tray 15. Therefore, it becomes possible to more stably lay the tray 15 on the slope, and
Cultivation and curing of the planted product 13 and laying construction on the rooftop can be performed more easily. Moreover, since the soil 18 has been hardened to some extent when it is laid on the roof,
Can be prevented from being carried away by wind and rain. in addition,
If cement powder is used as the binder, the soil 18 can be made alkaline, which is effective in controlling weeds.

In this rooftop greening system, a plurality of planting base materials 14 are laid on the rooftop of the building 11 in a state where the planting basement 14 having the above-mentioned structure is planted with the planting material 13. is doing. Therefore, when the planting product 13 is laid on the roof of the building 11, the planting product 13 can be easily handled in a state of being cultivated on the tray 15 of the planting base material 14. Therefore, the planting product 13 can be easily transported to the rooftop of the building 11 for installation without requiring troublesome transportation work and laying work, and the construction cost can be reduced.

The support 20 of the rooftop greening system is provided with the support boss portion 27 for supporting the corner portion of the planting base material 14 having the above-mentioned configuration in a state of being floated from the floor surface of the rooftop. Has been. For this reason, when laying the planting base material 14 on which the planting material 13 has been grown on the roof of the building 11, the tray 15 of the planting base material 14 may be supported in a state of being floated from the floor 12 of the roof. it can. Therefore, in the laid state of the planting base material 14, the drainage property and the air permeability of the soil 18 of the planted product 13 can be ensured, and the planted product 13 can be favorably grown in a crawling and prosperous state.

By the way, the vertical width of the gap between the tray 15 of the planting base material 14 and the floor surface 12 of the roof differs depending on the type of the planting material 13. For example, in the case of sedums such as Mexican sardines and Malba serrata, the vertical width of the gap is 1.0 to 2.0 cm (the optimum value is 1.5 cm),
0.3-0.7 in legumes such as clover and white clover
cm (optimum value is 0.5 cm) is suitable. Also, for herbs such as mint and lavender, 0.5-1.5 cm
(The optimum value is 1.0 cm), and for succulents such as aloe and cactus, 1.5 to 2.5 cm (the optimum value is 2.0 cm) is suitable.

(Modification) This embodiment can be modified and embodied as follows. -In the said embodiment, the aggregated soil 18a in the soil 18
Also, the type of the coarse aggregate 18b is arbitrarily changed to be configured. For example, as the aggregated soil 18a, aggregated soil artificially made from clay or the like is used, or as crushed limestone is used as the coarse aggregate 18b.

In the above embodiment, the mixing ratio of the aggregated soil 18a, the coarse aggregate 18b, etc. in the soil 18 may be arbitrarily changed. -In the above-mentioned embodiment, the shape of the tray 15 may be changed to another shape such as a flat square or a regular hexagon.

In the above-described embodiment, the shapes of the support tool 20 and the fixing tool 22 may be arbitrarily changed. For example, the support 20 and the fixture 22 should be flat hexagons. In the above-described embodiment, the net 17 made of synthetic resin fibers is used as the holding means for holding the soil 18, but instead of this, a large number of elongated papers (preferably having water resistance) or cloths are used. To use.
