DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating a method for greening a wall surface of a building according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes a plant cultivation configured to have water retention using zeolite as a porous material. The structure 2 for installation is mounted on the back side of the structure 1 for plant cultivation, and the mounting base for mounting the structure 1 for plant cultivation on a wall surface. The unitized structure for wall surface greening is formed, 4 is a lawn sheet, and 10 is a wall surface such as an outer wall or an inner wall of a building.

As shown in FIG. 2, the mounting base 2 is made of a water-storable plastic or metal container having rising pieces 2a on four sides (for example, a container having a length of 300 mm, a width of 300 mm and a height of the rising pieces of 25 mm). The mounting base 2 is placed in a mold, and zeolite as a porous material is injected onto the mounting base 2 and molded and solidified at a high pressure. A predetermined size (for example, length 30)
A wall greening unit structure 3 (0 mm, 300 mm in width, and 30 mm in height) is obtained.

The plurality of wall greening unit structures 3, 3... Obtained as described above are placed on the ground with the mounting base 2 side down, as shown in FIG. After water is contained in the plant cultivation structure 1 of the wall greening unit structures 3, 3,.
For example, a lawn sheet 4 with soil and roots (cut to the size of the upper surface of the plant cultivation structure 1) is laid on the plant cultivation structure 1 for a predetermined period (for example, two months). Degree) leave it alone. Then, the roots of the turf 4a enter between the zeolite grains of the plant cultivation structure 1, and the turf 4a is rooted on the plant cultivation structure 1. That is, a plurality of wall greening unit structures 3, 3... Cultivated with the turf 4a rooted are obtained. Then, the wall greening unit structures 3, 3,... Are attached to the wall surface 10 of the building with the side where the turf 4a is cultivated facing outside.

At the time of mounting, for example, as shown in FIG.
Attach two mounting brackets 6 as mounting means to each of a pair of opposite sides 2x and 2y of the mounting base 2 in the wall greening unit structure 3 on which the turf 4a is cultivated, and use the mounting bracket 6. Then, the wall greening unit structure 3 is attached to the wall surface 10.

As shown in FIG. 1, two mounting brackets 6, which are mounted on one side 2x of the mounting base 2,
6 is different from the interval b between the two mounting brackets 6 and 6 attached to the other side 2y. As a result, the wall greening unit structure 3 disposed at the bottom of the wall surface 10 is provided with all four mounting brackets 6.
After that, when mounting the wall greening unit structure 3 disposed at the upper position, the two mounting brackets 6, which are mounted at a distance b from each other, are attached.
6 are attached to the back surface 2u of the mounting base 2 of the wall greening unit structure 3 already mounted on the wall surface 10 and the wall surface 1
Since the two mounting brackets 6, 6 which are inserted between the mounting brackets 0 and 0 and which are mounted at a distance a from each other, need only be fixed to the wall surface 10 with screws or the like, the mounting operation is facilitated. The mounting bracket 6 may be mounted on the wall 10 by means other than screwing.

As described above, as shown in FIG.
From the lower side to the upper side of the wall, the wall greening unit structure 3
Are sequentially attached, the wall surface 10 of the building can be greened.

The above zeolite is mainly a hydrous silicate of aluminum, sodium and calcium,
It has a constant pore diameter in the range of 3 to 10 °, and this pore structure can hold a water content of about 35% of its volume. Further, the zeolite contains components such as calcium necessary for growing plants, as described above. Therefore, the plant cultivation structure 1 in which zeolite is formed and solidified can replenish the plant with necessary components such as water and calcium, and can grow the plant well. Moreover, since the specific gravity of zeolite is about 0.8, it can be made lighter as a whole, so that the wall greening unit structure 3 that is lightweight and easy to handle is obtained. As this zeolite, either a natural zeolite such as mordenite or a synthetic product may be used.

Further, as shown in FIG. 4, the plant cultivation structure 1 is formed into a block shape using a binder 12 so as to have a large number of voids 11a between a plurality of granular zeolites 11, 11. You. Thereby, the said structure 1 for plant cultivation will have air permeability by the said space | gap 11a, and can supply nitrogen etc. which are necessary for the growth of a plant to the cultivated plant.

The porous material used for molding the plant cultivation structure 1 may be any material other than zeolite as long as it is a porous material having water retention properties.

The above-mentioned structure 1 for plant cultivation may be formed using a porous material mixed with components necessary for growing plants. The components include nitrogen, phosphate, potassium, calcium, magnesium, sulfur, iron, manganese,
Boron, zinc, molybdenum, copper, chlorine, etc. are applicable. Thereby, fertilization to the plant can be performed, and the growing of the plant can be promoted.

As shown in FIG. 3, when the plant (turf 4a) is grown on the plant cultivation structure 1 by placing the wall greening unit structure 3 on the ground, the mounting base 2
Functions as a water storage means. That is, although the structure 1 for plant cultivation has water retention based on the pore structure, a portion of the unit structure 3 for wall surface greening accommodated in the mounting base 2 (from the dotted line 2i in FIG. 2). About the lower part), not only water retention based on the pore structure of zeolite etc.,
Since the mounting base 2 retains moisture in other voids, the mounting base 2 functions as water storage means. As described above, the unit structure 3 for wall surface greening has water retention based on the pore structure of the structure 1 for plant cultivation, and water storage by the mounting base 2. Therefore, when water is supplied to the structure 1 for plant cultivation, water is retained and stored in the unit structure 3 for wall greening.
The retained water and the stored water are absorbed by the soil and the roots of the plants by capillary action, so that the plants are always supplied with an appropriate amount of water. As a result, the plant grows, the roots of the plant extend between the grains of the porous material, and the structure for plant cultivation 1
The plant will take root on the top.

Embodiment 2 In the first embodiment, the lawn sheet 4 is left on the plant cultivation structure 1 of the wall greening unit structure 3 and the turf 4a is rooted and attached to the wall surface 10. FIG. As shown in the figure, a plant cultivation structure 1A having a plurality of recesses 1u provided on the upper surface was used, and plant seeds and soil were put into the recesses 1u to cultivate plants, and then the plants were cultivated. The wall greening unit structure 30 may be attached to the wall surface 10 of the building with the side facing outward. In addition, the said recessed part 1u can be formed by the exclusive molding upper mold at the time of molding the structure 1A for plant cultivation, for example.

Embodiment 3 Also, as shown in FIG.
At the time of molding the plant cultivation structure, the plant cultivation structure 1B formed by filling the seeds 40 and the soil 50 of the plant at a position on the upper 1t side may be used. That is, the granular zeolite 1 on the upper 1t side of the structure 1B for plant cultivation.
The unit structure 31 for wall greening in which the seeds 40 and the soil 50 of the plant are embedded in the gaps 11a between 1, 1 and 11,
After cultivating a plant on the wall greening unit structure 31,
The wall cultivation unit structure 31 may be attached to the wall surface 10 of the building with the side where the plant is cultivated facing outward.

Embodiment 4 As the mounting base used in each of the above embodiments, a mounting base 20 as shown in FIG. 7 may be used. A boss 21 for mounting the mounting bracket 6 to the mounting base 20 is provided on the inner bottom surface of the bottom plate 20a of the mounting base 20, and a boss 21 for increasing the bonding force between the mounting base 20 and the zeolite. A bonding force support member 22 including a plurality of rod-shaped pieces is provided. Therefore, when the zeolite is compressed and hardened at the time of the molding, it bites into the bonding strength support material 22, so that the plant cultivation structure 1 (or 1A, 1B) formed from the solidified zeolite and the mounting base 20 are firmly integrated. Wall greening unit structure 32 (see FIG. 8)
Is obtained. Since a plurality of recesses 23 are provided in the bottom plate 20a of the mounting base 20,
The unit structure 32 for greening the wall surface in which the structure 1 for plant cultivation and the mounting base 2 are more firmly integrated with each other is obtained by the combination 3, the bonding strength support 22 and the boss 21. In addition, if irregularities (jaggies) are formed on the outer periphery of the boss 21, the bonding strength between the plant cultivation structure 1 and the mounting base 20 can be further increased. Accordingly, the unit structure 32 for greening the wall surface is obtained from the above, in which the mounting base 20 does not separate from the structure 1 for plant cultivation even when mounted on the wall surface 10.

When cultivating a plant on the plant cultivating structure 1 with the wall greening unit structure 32 on the ground, the mounting base 20 also functions as a drainage means.
That is, the plurality of recesses 23 are formed in the bottom plate 20 a of the mounting base 20 as described above, and the space between the protrusions 24 on the back side of the recess 23 functions as the drainage channel 25. With this, if extra water is supplied,
This extra water is discharged from the wall greening unit structure 32, and is appropriately drained through the drainage channel 25.

FIG. 8 shows a cross section of a mounted state when the mounting base 20 is used. That is, the mounting bracket 6
As shown in FIG. 8, the boss 21 is screwed to the back side 20u of the mounting base 20 with a bolt 7 or the like via a tap (female screw) formed on the back side of the boss 21. As described above, if the screw is attached to the tap (female screw) for mounting, the mounting operation becomes easy. The mounting bracket 6 may be mounted on the mounting base 20 by means other than screwing. For example, it may be attached by means such as bonding or welding.

In the above description, the plurality of recesses 2 are formed in the bottom plate 20a.
Although the description has been given of the case where the mounting base 20 formed with 3 is used, a flat mounting base provided with a boss 21, a coupling force support member 22, and the like on one surface may be used.

The mounting bases 2 and 20 need not always be used. When the mounting bases 2 and 20 are not used, the plant is cultivated using a block-shaped plant cultivation structure configured to have water retention using a porous material such as zeolite, and the plant is cultivated. The structure for plant cultivation may be attached to the wall surface 10 of the building with the side facing out. Even in this case, the plant can be satisfactorily cultivated by the water retention ability of the plant cultivation structure. In this case, for example, the mounting bracket 6 may be directly attached to the back surface of the plant cultivation structure, and the plant cultivation structure may be attached to the wall surface 10. The attachment of the mounting bracket 6 to the back surface of the plant cultivation structure may be performed, for example, by providing a hole in the back surface of the plant cultivation structure, fitting a resin (for example, a tap) (female screw) or metal, or the like into the hole. By attaching the mounting bracket 6 to the wall and attaching the mounting bracket 6 to the wall surface 10, the plant cultivation structure in which the plant is cultivated can be mounted to the wall surface 10, and the wall greening operation can be easily realized. .

Incidentally, without using the mounting bracket 6,
The structure for plant cultivation or the unit structure for greening the wall surface on which the plant is cultivated may be directly attached to the wall surface 10 with a strong adhesive or the like.
