In the present embodiment, a water supply mechanism 600 described later is also integrated with the planting container 12. Therefore, the wall greening device 10 and the planting container 12 indicate the same thing. In addition, below, the wall surface greening apparatus 10 and the planting container 12 are used properly and described.

  As shown in FIGS. 1 and 2, as described above, unevenness is formed on the surface 100 </ b> A of the vertically arranged front plate (surface decorative plate) 100 that constitutes the design surface of the wall surface greening device 10. A plurality of shelves 110 are provided (see also FIG. 3). In the present embodiment, the surface 100A of the front plate 100 is colored in a rocky surface while unevenness (shelf portion 110) is formed in the rocky surface. That is, the surface 100A of the front plate 100 is designed to have a rock surface. And the plant 20 is planted in the opening part 112 (refer also FIG. 3) formed in these shelf parts 110, and as shown in FIG. 1, by attaching the wall surface greening apparatus 10 to the wall 90 of a room, In other words, by attaching the planting container 12 to the wall 90, the wall 90 of the room is greened to display a painting.

  In addition, the method of attaching the wall surface greening apparatus 10 (planting container 12) to the wall 90 may be any method. It may be hung on a picture rail or the like with a wire, or a hook or the like may be fixed to the wall 90 and hung on this hook. Alternatively, the wall 90 may be fixed with bolts and nuts. Moreover, you may fix with a volt | bolt and a nut. Moreover, you may fix to the wall 90 using the volt | bolt 50 and the nut 60 which couple | bond the front plate 100 and the back cover 400. FIG. Further, in this case, the back plate 300 may contact the wall 90 without providing the back cover 400 (the wall 90 may also serve as the back cover 400).

  Further, a plant 20 (a seedling) produced (grown) in advance in a separate production field is planted in the opening 112 of the shelf 110. Moreover, in each figure and this description, although the same code | symbol 20 is attached | subjected to each plant, you may plant a different kind of plant in the opening part 112 of each shelf part 110. FIG.

  Moreover, the vertical direction upper side in the state which attached the wall surface greening apparatus 10 (planting container 12) to the wall 90 in this way is the arrow Z direction of each figure, and a horizontal direction front side (surface 100A side) is the arrow X direction. Yes, the left side in the horizontal direction is the arrow Y direction. The X direction is the width direction and the Y direction is the longitudinal direction.

  As shown in FIGS. 1 and 3, an opening 112 is formed in the shelf 110 of the front plate 100, and a through-hole 114 is formed obliquely downward from the opening 112 as shown in FIGS. And opened in the back surface 100B (see also FIG. 8). As shown in FIG. 4, grooves 118 (concave grooves that are concave toward the front surface 100A side (X direction)) are formed in a lattice shape (up, down, left, and right) on the back surface 100B of the front plate 100. .

  As shown in FIG. 1, in this embodiment, an upper receiving portion 102 having an L-shaped cross section that protrudes toward the back side is formed at the upper end portion of the back surface 100 </ b> B of the front plate 100. In addition, a bottom portion 103 having an L-shaped cross section that protrudes toward the back side is formed at the lower end portion of the back surface 100B of the front plate 100.

  In the present embodiment, the surface plate 100 is formed with the above-described unevenness, shelf portion 110, opening portion 112, and through-hole 114 on a board having a thickness of about 50 mm to 150 mm (a board before being processed). The surface 100A is colored like a rock surface. In addition, the formation method of an unevenness | corrugation, the shelf part 110, the opening part 112, and the through-hole 114 is not specifically limited. For example, you may shape | mold the surface board 100 in which the unevenness | corrugation, the shelf part 110, the opening part 112, and the through-hole 114 were formed by shaping | molding.

  As a raw material of the front plate 100 (board), a light-weight material such as urethane foam that has heat insulation and water permeability is reinforced by fiber reinforcement or the like. The surface 100A of the front plate 100 is colored with a weather resistant paint. In addition, as a raw material of the surface board 100 (board), if it has heat insulation, it will not specifically limit. For example, wood or gypsum board may be used. Moreover, it is desirable that it is impermeable. However, even if the material itself constituting the front plate 100 is not water-impermeable, the water-impervious performance may be ensured by coating the front plate 100 with water-impermeable coating or coating.

  Moreover, it is preferable that the thickness (see FIG. 1) of the surface plate 100 after the design processing is thin within a range in which strength and growth performance of the plant 20 are ensured.

  The water retention base (planting base) 200 is made of a material having high water retention that enables the plant 20 to be rooted, for example, felt, nonwoven fabric, urethane sponge, palm fiber, water guide sheet and the like. In addition, heat sensitive gel and water retention gel may be mixed in these materials to improve water retention performance.

  Similar to the front plate 100, the back plate 300 is made of a heat insulating and water-impermeable material, such as a panel, a vinyl chloride board, a slate plate, a metal plate, wood, urethane foam or the like. The material of the back plate 300 is not particularly limited as long as it has heat insulation properties. Moreover, it is desirable that it is impermeable. However, even if the material itself constituting the back plate 300 is not water-impermeable, non-water-permeable performance may be ensured by applying water-impermeable coating or coating.

  The back cover 400 is made of a material having a strength that can be fixed to a wall, such as a panel, a vinyl chloride board, a slate plate, a metal plate, or wood.

  The frame 500 is made of a material having strength that can be fixed to a wall, steel, aluminum, resin, or the like. Further, decoration or coloring may be applied to the surface (design surface) of the frame 500 like a frame.

  In the present embodiment, the back plate 300 and the back cover 400 are configured as separate members, but the back plate 300 may also serve as the back cover 400.

  Next, a water supply mechanism 600 that supplies (irrigates) water to the water retention base (planting base) 200 will be described.

  As shown in FIG. 7, the water supply mechanism 600 includes a water supply hose 610 provided with a drip device 620 such as a plurality of dripping nipples, and a drainage case 650.

  As shown in FIG. 1, the water supply hose 610 is disposed along the longitudinal direction (Y direction) above the upper end 200U of the water retention base 200 in the upper part of the wall greening device 10 (planting container 12). (As shown in FIG. 1, the water supply hose 610 is disposed below the upper receiving portion 102 of the front plate 100). As shown in FIG. 7, the water supply hose 610 is provided with a plurality of drip devices 620 at intervals in the longitudinal direction.

  As shown in FIG. 8, the drip device 620 has a mechanism in which the water droplets S drop when water is supplied to the water supply hose 610. Note that the drip device 620 has the same configuration (commercially available product) as the conventional one, and thus the description thereof is omitted.

  In the present embodiment, the drip device 620 is provided at intervals of about 10 cm to 15 cm along the longitudinal direction. In the present embodiment, the water droplet S having a discharge amount of about 3 liters / hour is used.

  As shown in FIG. 1, the drainage case 650 is disposed along the longitudinal direction below the water retention base 200 in the lower part of the wall greening device 10 (planting container 12) (as shown in FIG. 1). In addition, the drainage case 650 is provided in the receiving portion 103). As shown in FIGS. 1 and 7, the lower end portion 220 of the water retention base 200 is placed in the drainage case 650.

  In addition, as shown in FIG. 2, the water supply port 630 for supplying water to the water supply hose 610 is provided in the upper part in the side surface of the wall surface greening apparatus 10 (planting container 12). In the lower part of the side surface of the planting container 12), a drain outlet 660 for draining water accumulated in the drain case 650 is provided.

  And by supplying water from the water supply port 630, the water droplet S (refer FIG. 8) falls from each drip apparatus 620 to the water retention base 200, and water supplies (irrigation). The supplied water penetrates the entire water retention base 200 by the capillary force of the water retention base 200. The supplied (irrigated) water penetrates the entire water retention base 200 and then becomes surplus water and is stored in the drainage case 650. Excess water stored in the drainage case 650 can be extracted from the drainage port 660.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 1, the plant 20 planted in the opening 112 of the shelf 110 of the front plate 100 grows in a vertical direction (along the direction of gravity) perpendicular to the ground. Growth is improved compared to the case of growing (growing) substantially parallel (direction perpendicular to the direction of gravity).

  Further, the roots 22 of the planted plant 20 can come out from the opening of the through-hole 114 on the back surface 100 </ b> B of the front plate 100 and can spread the root over the entire area of the water retention base 200. Furthermore, the plant 20 can stretch the root 22 along the groove 118 (see FIG. 4) formed on the back surface 100 </ b> B of the front plate 100. Therefore, the plant 20 can easily stretch the root 22 over a wide area of the water retention base 200. Thereby, the growth of the plant 20 further improves.

  In addition, the water retention base 200 is sandwiched between the front plate 100 and the back plate 300 made of a heat insulating material, and the front plate 100 is not opened except for the opening 112 of the shelf 110. Temperature rise or temperature drop is suppressed. Moreover, evaporation of moisture from the water retention base 200 is suppressed. Further, since the front plate 100 and the back plate 300 are made of a water-impermeable material, evaporation of moisture is further suppressed.

  Therefore, the temperature of the root 22 of the plant 20 is stabilized and drying is suppressed, so that the growth of the plant 20 is improved.

  Further, the water supply mechanism 600 supplies water from the upper end 200U of the water retention base 200, drains from the lower end portion 220 of the water retention base 200, and is poured. Therefore, compared with a method in which excess water drained from the lower end portion 220 is pumped up and supplied to the water retention base 200 again, that is, in a circulation method in which water is circulated, the oxidation of water in the water retention base 200 by the root acid is reduced. It is suppressed. Therefore, the growth of the plant 20 is improved.

  Here, when the present inventor circulated water over a long period of time with this configuration, growth failure such as poor growth (growth) occurred. When this inventor investigated and analyzed this cause, it turned out that PH of the circulating water (water in the water retention base | substrate 200) circulating is falling and oxidizing. Therefore, it is considered that the cause of the growth failure is due to oxidation of the circulating water. The oxidation of the circulating water is considered to be a phenomenon caused by increasing the concentration of root acid (organic acid) secreted by the root 22 of the plant 20 in the circulating water by circulating the water. Note that the disadvantage of such a circulation system (plant growth failure due to oxidation of circulating water) is the first discovery by the present inventors.

  Moreover, in this embodiment, the water droplet S is dropped from the drip device 620 provided in the water supply hose 610, and the entire water retaining base 200 is supplied (irrigated). That is, by flowing water through the water supply hose 610, it is easy. Water can be supplied to the water retention base 200 (can be poured).

  Moreover, since the excess water drained from the lower end portion 220 of the water retention base 200 is temporarily stored in the drainage case 650 and the stored water is drained, the surplus water can be easily treated.

  In addition, by attaching the planting container 12 (wall greening device 10) in which the front plate 100, the back plate 300, the water retention base 200, and the water supply mechanism 600 are integrated to the wall 90 of the room, the painting can be displayed on the wall 90. In addition, the room wall 90 is easily greened.

  Next, a modification of the water supply mechanism will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view of a modified water supply mechanism 700 as viewed obliquely from the front, and FIG. 10 is a partially enlarged perspective view of the modified water supply mechanism 700 of FIG.

  As shown in FIG. 9, the deformed bottom water supply mechanism 700 has a water supply case 710 and a drainage case 650.

  The water supply case 710 is disposed in the upper part of the planting container 12 along the longitudinal direction. Then, the upper end portion 210 of the water retention base 200 is bent and immersed in the water stored in the water supply case 710.

  Then, as shown in FIG. 10, by supplying water from the water supply port 630 and storing the water in the supply case 710, the water retention base 200 penetrates the entire water retention base 200 by the capillary force. The surplus water is similarly stored in the drainage case 650, and the stored surplus water can be extracted from the drainage port 660.

  In addition, since the longitudinal direction whole area of the upper end part 210 of the water retention base 200 is immersed in the water stored in the water supply case 710 like this modification, it is more uniformly in the longitudinal direction whole area of the water retention base 200. Water can be supplied (penetrated).

  Here, the planting container 12 (wall surface greening device 10) does not necessarily have to be attached to the wall and decorated. For example, as shown in FIG. In this case, the greening of the wall surface refers to any wall surface in the room space that is desired to be greened. That is, the surface 100A of the front plate 100 is a wall surface that is desired to be green. In such a case, the front plate 100 may not be arranged vertically. It may be substantially vertical (may have some angle).

  In addition, substantially vertical is an angle range in which growth failure such as growth (growth) remarkably inferior to the case where the planting container (wall greening device) to which the present invention is applied is arranged vertically does not occur. However, it is 60 ° to 90 ° with respect to the ground.

  Moreover, in this embodiment, although the planting container 12 was attached to the wall 90, as the wall 90 of the dashed-two dotted line (imaginary line) shown in FIG. 1 shows, the wall surface greening apparatus 10 (planting) in the wall 90 The container 12) may be embedded.

  Specifically, as shown in FIG. 11, the entire surface of the wall 90 (or substantially the entire surface) is composed of the front plate 100 (the surface 100A thereof). In FIG. 11, a plurality of front plates 100 (a plurality of wall surface greening devices 10) are arranged to constitute the wall 90. However, the entire surface of the wall 90 (also abbreviated as one wall plate). The entire surface) may be configured. Alternatively, only a part of the wall 90 may be constituted by the front plate 100 (the surface 100A thereof).

  In the case of such a configuration, the drain outlet 660 may be connected to a drain pipe (drainage officer) in the building to drain excess water.

  Furthermore, you may attach the planting container 12 not to the wall 90 of a room but to a building outer wall. Alternatively, the front plate 100 may constitute part or all of the outer wall. In other words, the wall greening device 10 (planting container 12) may be embedded in the building outer wall (the wall 90 in FIGS. 1 and 11 may be the outer wall). . Note that both the building inner wall and the building outer wall may be greened.

  Moreover, when applying this invention to a building outer wall, you may make it drain an excess water directly to soil or a sewer, without providing the drainage case 650. FIG. Moreover, you may make it supply water using rainwater.

  In addition, when the present invention is applied to a building outer wall or a building inner wall (wall 90), the temperature is reduced by the front plate 100 and the back plate 300 made of the heat insulating material of the wall surface greening device 10 and the water retaining base 200 including water. It is possible to obtain effects (inhibition of temperature rise of the building (structure) in the summer, heat insulation effect of the building (structure) in the winter) and soundproofing effect.

  In particular, the greening of the outer wall of the building can provide an outer heat insulating effect, a storm resistance effect, a fireproof effect, a fire spread prevention effect (effect by the plant 20 and the supplied water retention base 200), and the like. Moreover, the improvement of the landscape by a plant and the warming prevention effect (CO2 absorption effect) are also acquired.

  The present invention is not limited to the above embodiment. Needless to say, various embodiments can be implemented without departing from the scope of the present invention.

  For example, in the above-described embodiment, the water supply to the water retention base 200 is a pouring method, but is not limited to this. A circulation system may be used in which surplus water in the drainage case 650 is pumped up and supplied to the water retention base 200. However, when circulating over a long period of time, the concentration of root acid increases and affects the growth of the plant 20 as described above. Therefore, the circulating water may be exchanged before the influence is exerted. In other words, water may be circulated within a period in which plant growth is not affected.

  Further, for example, in the above embodiment, the greening in the building outer wall, the building inner wall, and the room is targeted, but the present invention is not limited to this. For example, a party in a room or an outdoor fence or fence may be used as a greening target.
