JP-A-2005-261208 Japanese Patent Laid-Open No. 9-252654

  In the wall greening structure described in Patent Document 1, since the tip of the vine plant is locked to the locking tool, if the distance between the locking tool and the container is too large, the vine plant is locked by its own weight. It becomes difficult to lock the tool. Moreover, in the support apparatus of patent document 2, since the spot culture medium is attached to the net member, in order to perform wall surface greening in a wide range, a large net member corresponding to the greening range is required. For this reason, the apparatus becomes large.

  This invention is made | formed in view of such a situation, The objective is to manufacture easily the wall surface greening material suitable for the wall greening with respect to a wide range.

  In order to achieve the above object, the present invention provides a vine plant in which attached roots are rooted from the middle of a vine, a first container in which a first medium for rooting a fixed root of the vine plant is housed, A wall greening material, which contains a second medium for rooting the adherent root, and has a second container disposed in the middle of the vine, and is disposed along the wall surface portion for greening the wall surface portion of the building A first step of growing a vine of a climbing plant while drooping in a state where the first container having the fixed root rooted in the first medium is installed at a high place, A second step of holding the tip of the vine in a state of being pressed against the second medium in the second container placed in a low place until the attached roots are rooted in the second medium; In the state where the second container is moved to a high place, the vine is suspended and grown. And performing a third step that.

  According to the method for producing a wall greening material of the present invention, the vine of a climbing plant is grown while hanging, and the tip of the hanging vine is held in a state where it is pressed against the medium. The wall surface greening material which consists of the combination of the container in which the plant and the culture medium were accommodated can be manufactured.

  In the manufacturing method described above, in the state where the tip portion of the vine suspended in the third step is pressed against another second medium in another second container installed in a low place, the attached root is When performing the 4th process hold | maintained until it roots in the said other 2nd culture medium, an attached root can be rooted in another 2nd culture medium also with another 2nd container with an easy process.

  In the manufacturing method described above, the distance in the height direction from the first container to the second container in the second step, and the height direction from the second container to the other second container in the fourth step. When the intervals are aligned, the wall greening material in a state where the intervals between the containers are aligned can be easily manufactured.

  In the manufacturing method described above, when the first container and the second container are constituted by pot-shaped members, and the first medium and the second medium are granular media, the handling is easy and the water is drained. Therefore, the wall surface greening material can be manufactured more easily.

  In the above-described production method, when the climbing plant is selected from the group consisting of ivy, nosenkazura, himeitabi, oitabi, itabikazura, hedera canariensis, and hedera helix, it is ensured that the adherent root is in the second medium. Can be netted.

  ADVANTAGE OF THE INVENTION According to this invention, the wall surface greening material of the simple structure which consists of a combination of the container in which the vine plant and the culture medium were accommodated can be manufactured easily.

It is a perspective view of the apartment house where the window side surface was greened by the wall greening material. It is a figure explaining the structure of a wall surface greening material. It is a figure explaining the internal structure of the cultivation tank in which the pot was accommodated. It is a figure explaining the structure of a culture solution circulation unit. It is a figure explaining the planter installed in the middle floor of a building. (A)-(f) is a figure explaining the manufacturing method of a wall surface greening material in time series, respectively. (A)-(f) is a figure explaining the other manufacturing method of a wall surface greening material in time series, respectively.

  Embodiments of the present invention will be described below. Here, the case where the window side surface is greened will be described as an example for the three-story apartment house 1 shown in FIG. In this example, the apartment house 1 corresponds to a building of the present invention, and the window side surface of the apartment house 1 corresponds to a wall surface part to be greened.

  The apartment house 1 has a substantially rectangular parallelepiped appearance. A balcony 3 provided with a handrail 2 is provided at each level of the apartment house 1. As described above, since the exemplary apartment house 1 has three floors, the balcony 3 is provided on each floor from the first floor to the third floor. Moreover, the handrail 4 is provided in the roof part in the apartment house 1 along the outer periphery.

  A wall greening material 5 is disposed on the surface of the apartment house 1 on the balcony 3 side, that is, the window side surface of the building, and covers the window side surface. This wall greening material 5 uses a vine plant, and is installed in the height direction of the apartment house 1 from the ground surface near the apartment house 1 to the rooftop. A large number of wall greening materials 5 are installed side by side so as to cover the width direction of the apartment house 1.

  As shown in FIG. 2, the wall greening material 5 includes a vine plant 11 and a medium 12 a (first medium) on which the root 11 a (root rooted from the end of the vine) of the vine plant 11 takes root. The housed lower end pot 12 (first container) and the medium 13a, 14a (second medium) in which the attached roots 11b of the climbing plant 11 (indeterminate roots, roots rooted from the middle of the vine) are rooted. The pots 13 and 14 (second container) and the upper end pot 15 (third container) in which the medium 15a (third medium) in which the attached root 11b at the tip of the climbing plant 11 is rooted are accommodated.

  These pots 12 to 15 are bottomed cylindrical members whose upper surfaces are open and have a truncated cone-like appearance. The bottom plate is provided with a drain opening. Such pots 12 to 15 are produced by molding a synthetic resin. In the present embodiment, two intermediate pots 13 and 14 are provided at different positions in the middle of the vine. For convenience, in the following description, the lower intermediate pot is referred to as a lower intermediate pot 13, and the upper intermediate pot is referred to as an upper intermediate pot 14.

  The culture mediums 12a to 15a accommodated in the pots 12 to 15 may be any medium as long as the vine plant 11 is rooted. However, a granular medium with good drainage is preferable because the vine plant 11 is hydroponically cultivated in the cultivation tank. . In the present embodiment, a mixture of zeolite and Hinata pumice is used. Since Hyuga pumice has a lower specific gravity than zeolite, the weight can be adjusted by the mixing ratio, and the handling of each pot 12 to 15 can be facilitated. Moreover, since it is granular, it is easy to extend the roots.

  This wall greening material 5 is a culture medium for pots 12 to 15 in which roots (fixed root 11a and attached root 11b) rooted at the base, tip, and middle positions of the climbing plant 11 are provided at the respective positions. It is rooted in 12a-15a. For this reason, the vine plant 11 is required to root the attached root 11b from the middle of the vine in addition to the fixed root 11a.

  Examples of such vine plants 11 include Hedera bhombea, Campis X Tagliabuana, Hicusabi (Ficus thunbergii), Ficus pumira, Ficus nipponica, Hedera canariensis (Hedera canariensis). ), And Hedera helix are preferably used.

  Among these vine plants 11, Hime Tabi, Oitabi, Itabikazura, Hedera canariensis, and Hedera helix are evergreen perennials, and are therefore preferably used when it is desired to plant trees throughout the four seasons. Hedera helix also has good cold resistance, so it can grow well in many regions including cold regions. In addition, because it is perennial deciduous, it is preferably used when no greening is required in winter.

  As shown in FIG. 2, each pot 12-15 is arrange | positioned at a corresponding hierarchy. For this reason, the length of the vine from the lower end pot 12 to the lower intermediate pot 13 is set to be slightly longer than the distance from the ground surface to the balcony (handrail) on the second floor. The length of the vine from the lower intermediate pot 13 to the upper intermediate pot 14 is set to be slightly longer than the distance from the balcony on the second floor to the balcony on the third floor. Similarly, the length of the vine from the upper middle pot 14 to the upper end pot 15 is set to be slightly longer than the distance from the balcony on the third floor to the rooftop.

  As shown in FIG.1 and FIG.2, the lower end pot 12 is accommodated in the cultivation tank 21 arrange | positioned by the ground surface vicinity of the balcony 3 of the 1st floor. This cultivation tank 21 is a part which supplies a culture solution with respect to the planted vine plant 11. For this reason, as shown in FIG. 1, a culture solution circulation unit 22 is connected to the cultivation tank 21, and the culture solution from the culture solution circulation unit 22 is supplied to the cultivation tank 21 through the supply pipe 23 and surplus. Is recovered in the cultivation tank 21 through the recovery tube 24.

  As shown in FIG. 1, the cultivation tank 21 has a rectangular parallelepiped appearance and is configured as a box having a cavity inside. For example, as shown in FIG. 3, the cultivation tank 21 has a rectangular parallelepiped cultivation tank main body 31 whose upper surface is opened, and a lid 32 that covers the upper surface opening of the cultivation tank main body 31 from above. The height of the cultivation tank 21 is set to such an extent that the vine plant 11 rooted in the medium 12a of the lower end pot 12 can be guided with a margin. The depth (length in the short side direction) of the cultivation tank 21 is determined so that one lower end pot 12 can be accommodated without excess or deficiency, and the width (length in the long side direction) of the cultivation tank 21 is plural. The lower end pots 12 (9 in the example of FIG. 3) are determined so as to be accommodated without excess or deficiency. And the lower end pot 12 is accommodated in the substantially rectangular parallelepiped space divided by the cultivation tank main body 31 and the cover body 32 in the state along the longitudinal direction of the cultivation tank 21. As shown in FIG.

  A supply side opening 33, a drain side opening 34, and a side opening 35 (see FIG. 1) are formed in the side plates 31a and 31b of the cultivation tank main body 31. The supply side opening 33 is formed in the side plate on the short side that constitutes the cultivation tank main body 31. The distal end portion of the supply pipe 23 that supplies the culture solution is inserted into the supply side opening 33. The drain side opening 34 is provided at the lower end position of the side plate provided with the supply side opening 33. The leading end of the collection tube 24 for collecting the culture solution is inserted into the drain side opening 34. The side opening 35 is provided in the long side side plate which comprises the cultivation tank main body 31 in the rectangular shape long to a long side direction. The side opening 35 serves as an outlet through which the vine plant 11 extending from the lower end pot 12 accommodated in the cultivation tank 21 extends outside the cultivation tank 21.

  A tip portion of the supply pipe 23 led into the cultivation tank 21 through the supply side opening 33 is connected to the injection pipe 36. The injection pipe 36 is a pipe-like member in which a plurality of culture solution injection holes (not shown) are formed, and is arranged along the longitudinal direction of the cultivation tank 21. The culture solution sprayed from each spray hole penetrates into the culture medium 12 a accommodated in the lower end pot 12.

  The distal end portion of the collection pipe 24 attached to the drain side opening 34 opens at a position close to the bottom plate 31 c of the cultivation tank main body 31. Since the bottom plate 31c is slightly inclined downward toward the drain side opening 34, the surplus portion that has not been absorbed by the culture medium 12a and the vine plant 11 out of the culture solution sprayed from the spray pipe 36 is the surface of the bottom plate 31c. Flows toward the drain side opening 34. Then, it flows into the recovery pipe 24 through the drain side opening 34 and is recovered.

  As shown in FIG. 4, the culture fluid circulation unit 22 includes a culture fluid generator 41 and a culture fluid tank 42.

  The culture solution generation unit 41 is a portion that generates a culture solution from tap water and a concentrated solution, and includes a concentrated solution mixer 43 and a concentrated solution tank 44. The concentrate mixer 43 mixes the concentrate stored in the concentrate tank 44 with tap water to generate a culture solution. The concentrated solution mixer 43 appropriately replenishes the culture solution so that the culture solution in the culture solution tank 42 is maintained at a specified level.

  The culture solution tank 42 is a portion that stores a culture solution that is circulated and used with the cultivation tank 21 and is configured by a light-shielding container in order to suppress the generation of algae. A base end portion of the supply pipe 23 and a base end portion of the recovery pipe 24 are inserted into the culture medium tank 42. The proximal end opening of the supply pipe 23 is located in the vicinity of the bottom plate of the culture medium tank 42, and the proximal end opening of the recovery pipe 24 is located in the upper part of the culture medium tank 42.

  A liquid supply pump 45 is provided in the middle of the supply pipe 23. The liquid supply pump 45 delivers the culture solution stored in the culture solution tank 42 toward the cultivation tank 21. A recovery pump 46 is provided in the middle of the recovery pipe 24. The collection pump 46 sends out the excess culture solution collected by the collection tube 24 to the culture solution tank 42 side. Accordingly, the culture solution stored in the culture solution tank 42 is sent to each culture tank 21 using the feed pump 45 as power, and excess culture solution in each culture tank 21 is sent to the culture solution tank 42 using the recovery pump 46 as power. Collected.

  Next, the intermediate pot (lower intermediate pot 13 and upper intermediate pot 14) and the planter 51 that supports these intermediate pots 13 and 14 will be described. As described above, the intermediate pots 13 and 14 are also constituted by a cylindrical container having an open top surface, and a granular medium in which zeolite and Hinata pumice are mixed is accommodated therein.

  As shown in FIG. 5, the intermediate pots 13 and 14 are accommodated in a planter 51 installed on the second or third floor (corresponding to the middle floor of the building) of the apartment house 1. The planter 51 is a long rectangular container having an open upper surface (the planter 51 shown in FIG. 5 is partially cut away), and its height is higher than the height of the intermediate pots 13 and 14. It is set to a slightly high level. The depth (length in the short side direction) of the planter 51 is determined so that one intermediate pot 13 and 14 can be accommodated without excess or shortage, and the width (length in the long side direction) of the planter 51 is It is determined so that the plurality of intermediate pots 13 and 14 can be accommodated without excess or deficiency.

  The width of the planter 51 is preferably determined so as to accommodate the same number of intermediate pots 13 and 14 as the number of lower end pots 12 that can be accommodated in the cultivation tank 21. If comprised in this way, it will become possible to make the wall surface greening material 5 into a group by the storage unit to the cultivation tank 21, and since installation work can be performed for every group, the efficiency of installation work can be achieved.

  The side plate on the balcony 3 side in the planter 51 is provided with a downward U-shaped hook 51a. One of the pair of downward pieces of the hook 51a is fixed to the upper end of the side plate by screwing or the like. Then, the inverted L-shaped portion protruding outward from the side surface of the planter 51 is hooked on the handrail 2 from above. In FIG. 5, only one hook 51 a is illustrated, but a plurality of hooks 51 a are attached to the planter 51 at intervals. For this reason, the planter 51 can be installed on the handrail 2 in a stable state by hooking each hook 51 a to the handrail 2.

  Next, the upper end pot 15 and the planter 52 that supports the upper end pot 15 will be described with reference to FIG. As described above, the upper end pot 15 is also constituted by a cylindrical container having an open upper surface, and a granular medium in which zeolite and Hinata pumice are mixed is accommodated therein. The planter 52 that accommodates the upper end pot 15 is different from the planter 51 for the intermediate pots 13 and 14 in that it does not have a hook 51a for hooking on the handrail 2, but the other parts are configured similarly. For this reason, detailed description is omitted. Similar to the planter 51 for the intermediate pots 13 and 14, a hook 51 a is provided when hooking the rooftop handrail 4.

  As described above, the wall greening material 5 of the present embodiment accommodates the vine plant 11 in which the attached root 11b is rooted from the middle of the vine and the culture medium 12a in which the constant root 11a of the vine plant 11 is rooted. The lower end pot 12 and the culture mediums 13a and 14a to which the attached root 11b takes root are accommodated, and are rooted from the lower intermediate pot 13 and the upper intermediate pot 14 arranged at different positions in the middle of the vine and from the tip of the vine. And an upper end pot 15 in which a culture medium 15a in which the attached root 11b is rooted is accommodated.

  As shown in FIG. 2, the lower end pot 12 is installed near the ground surface corresponding to the first floor of the apartment house 1, and the lower intermediate pot 13 is installed on the balcony 3 located on the second floor of the apartment house 1. . Similarly, the upper intermediate pot 14 is installed on the balcony 3 located on the third floor of the apartment house 1, and the upper end pot 15 is installed on the roof of the apartment house 1. That is, each pot 12-15 is arrange | positioned so that the vine plant 11 may extend in a height direction. And as shown in FIG. 1, the wall side greening material 5 is arranged side by side, and the window side surface of the apartment house 1 is greened. Thus, wall greening over a wide range can be performed with a simple configuration comprising a combination of the pots 12 to 15 in which the vine plant 11 and the culture media 12a to 15a are accommodated.

  Moreover, since the vine plant 11 is supported in the state spanned between several pots, the weight of the vine plant 11 can be borne by each pot 12-15. Therefore, by appropriately managing the length of the vine between the pots, a problem that the vine is excessively pulled by its own weight can be suppressed.

  In addition, when wall surface greening is performed, a plurality of wall greening materials 5 may be installed side by side over a range where greening is desired, and an arbitrary range can be easily greened. At that time, the density at which the climbing plant 11 grows can be easily adjusted by adjusting the interval between the adjacent wall greening materials 5. That is, the amount of sunlight transmitted can be easily adjusted. Further, by adjusting the interval between pots for each level, it is possible to partially increase or decrease the amount of sunlight transmitted in the middle floor.

  Furthermore, in this embodiment, since the lower end pot 12 in which the fixed root 11a rooted in the culture medium 12a is accommodated in the cultivation tank 21 and the culture solution is supplied, the nutrients necessary for the growth of the climbing plant 11 are fixed root. It can be spread throughout the vine plant 11 through 11a.

  Next, the manufacturing method of the wall surface greening material 5 mentioned above is demonstrated. The wall greening material 5 grows a climbing plant 11 in which a fixed root 11a is rooted in a medium 12a in a lower end pot 12, and the attached root 11b rooted in the middle of the vine is converted into a lower intermediate pot 13 or an upper intermediate pot. 14, and the attached root 11 b rooted at the tip of the vine is further rooted in the upper end pot 15. This will be described in detail below.

  First, as shown in FIG. 6 (a), a lower end pot 12 in which a fixed root is rooted in a medium (first medium) is placed on a shelf 61 (high place), and the vine of the climbing plant 11 is grown while hanging. (First step). Here, the shelf 61 is, for example, a so-called pipe frame in which pipes are assembled into a cross beam, and the height of the shelf 61 is determined according to the height of each floor of the apartment house 1. Then, the vine is grown until the tip reaches the vicinity of the ground surface G.

  If the vine has grown sufficiently, as shown in FIG. 6 (b), the tip of the suspended vine is placed in the medium in the lower intermediate pot 13 installed in the ground surface G (low place) (second In the state pressed against the culture medium), hold until the attached root of the pressed part is rooted in the culture medium (second step). The vine is held by, for example, placing a weight 62 on the vine so that the vine does not hurt. In the present embodiment, a short steel pipe material is used as the weight 62. In addition, it is preferable to support the pipe material using a spacer or a support so that the vine does not hurt.

  When the adherent root 11b has rooted in the medium in the lower intermediate pot 13, the lower end pot 12 is placed on the ground surface and the lower intermediate pot 13 is placed on the shelf 61 as shown in FIG. Thereby, the part from the lower end pot 12 to the lower intermediate pot 13 in the climbing plant 11 is prevented from being entangled with other members such as a pipe frame or the ground. And about the lower intermediate | middle pot 13 installed in the shelf 61, the vine of the vine plant 11 which attached the attachment root is made to grow until the front-end | tip part reaches the vicinity of the ground surface G (3rd process).

  When the vine has grown sufficiently, as shown in FIG. 6 (d), the tip of the hanging vine is pressed against the medium (other second medium) in the upper intermediate pot 14 installed on the ground surface. In this state, hold until the attached root of the pressed portion is rooted in the culture medium (fourth step). The holding here is also performed using the weight 62 in the same manner as the procedure described in the lower intermediate pot 13.

  If the adherent root 11b has rooted in the medium in the upper intermediate pot 14, the lower end pot 12 and the upper intermediate pot 14 are placed on the shelf 61 and the lower intermediate pot 13 is placed on the ground surface G as shown in FIG. Put. Thereby, the part from the lower end pot 12 to the upper middle pot 14 in the vine plant 11 is arranged in a substantially V shape via the lower middle pot 13. This prevents this portion from being entangled with other members such as a pipe frame. And about the upper side middle pot 14 installed in the shelf 61, like the process so far, the vine of the vine plant 11 which rooted the attachment root is grown until the front-end | tip part reaches the surface G vicinity (5th). Process).

  If the vine has grown sufficiently, as shown in FIG. 6 (f), the state where the tip of the hanging vine is pressed against the medium (third medium) in the upper end pot 15 installed on the ground surface G. Then, hold until the attached root of the pressed part is rooted in the medium (sixth step). The holding here is also performed using the weight 62 in the same manner as the procedure described in the lower intermediate pot 13 and the upper intermediate pot 14. And when the adhesion root of the tip part of a vine roots in a culture medium, manufacture of the wall surface greening material 5 will be complete | finished.

  Thus, in the manufacturing method of this embodiment, the vine of the vine plant 11 is grown while drooping, and the simple process of holding the tip of the hanging vine in a state pressed against the medium is repeated. Thus, the wall surface greening material 5 composed of a combination of a plurality of pots 12 to 15 in which the vine plant 11 and the culture media 12a to 15a are accommodated can be manufactured.

  Moreover, in this embodiment, since the height of the shelf 61 from the ground surface G is made constant, the distance in the height direction from the lower end pot 12 to the lower intermediate pot 13 in the second step, and the lower side in the fourth step The intervals in the height direction from the intermediate pot 13 to the upper intermediate pot 14 are aligned. Thereby, the length of the climbing plant 11 from the lower end pot 12 to the lower intermediate pot 13 is substantially equal to the length of the climbing plant 11 from the lower intermediate pot 13 to the upper intermediate pot 14. Therefore, the wall greening material 5 having a form suitable for a building having a constant height on each floor, such as the apartment house 1, that is, the wall greening material 5 provided with the pots 12 to 15 at regular intervals suitable for installation on each floor. Can be easily manufactured.

  FIGS. 7A to 7F are diagrams for explaining another manufacturing method of the wall surface greening material 5, and correspond to FIGS. 6A to 6F described above, respectively. Explaining the difference from the manufacturing method described above, in the previous manufacturing method, the pot was moved between the shelf 61 and the ground surface G every time the attached root of the tip of the vine rooted in the medium. In the manufacturing method, the pots on the shelf 61 are not lowered onto the ground surface G by loosening the portions of the vines with an appropriate space between the pots in a substantially U shape.

  For example, when changing from the state of FIG. 7 (b) to the state of FIG. 7 (c), the bottom pot 12 and the lower intermediate pot 13 are installed on the shelf 61 with an appropriate space therebetween. Has a slack that does not get entangled in the part. Similarly, when the state shown in FIG. 7D is changed to the state shown in FIG. 7E, the lower intermediate pot 13 and the upper intermediate pot 14 are installed on the shelf 61 with an appropriate space therebetween. The vine has a slack that does not get tangled in other parts.

  Also in this manufacturing method, the wall surface greening material 5 which consists of the combination of the vine plant 11 and a pot can be manufactured easily similarly to the manufacturing method demonstrated previously. And in this manufacturing method, since the pot is not exchanged between the shelf 61 and the ground surface G, the manufacturing process can be simplified correspondingly.

  The above description of the embodiment is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof. For example, you may comprise as follows.

  Regarding the building to be greened, the apartment 1 is exemplified in the above-described embodiment, but other types of buildings can be similarly applied.

  Regarding the intermediate pots 13 and 14, in the above-described embodiment, the wall surface greening material 5 including two of the lower intermediate pot 13 and the upper intermediate pot 14 is illustrated, but the number of intermediate pots is not limited to two. One or three or more may be provided.

  In the above-described embodiment, the wall greening material 5 including the upper end pot 15 is illustrated, but the upper end pot 15 may be provided as necessary. And when the tip part of the vine is rooted in the culture medium in the upper end pot 15, the tip part of the vine is fixed by the upper end pot 15, so that the installation work becomes easy and the degree of freedom of arrangement increases. When the upper end pot 15 is omitted, a fixing tool (for example, a clip) for fixing the tip portion of the vine may be prepared.

  In the above-described embodiment, the medium in which the fixed root 11a of the climbing plant 11 is rooted is accommodated in the lower end pot 12, but may be accommodated in the upper end pot 15. In this case, the cultivation tank 21 is installed on the roof of the apartment house 1, and the vine plant 11 is arranged from the upper side to the lower side. Even if it does in this way, the same effect is obtained.

  In the above-described embodiment, the culture solution is supplied to the fixed root 11a of the vine plant 11 by the cultivation tank 21, but the culture solution may be supplied by a human hand instead of the cultivation tank 21. In this case, a planter may be used instead of the cultivation tank 21, and the lower end pot 12 may be installed on the ground surface.

  In the above-described embodiment, the shelf 61 is described as a high place and the ground surface G is described as a low place. Here, the high place and the low place represent a relative height relationship. That is, the height position that is a starting point for growing the vine of the climbing plant 11 is a high place, and the position where the attached root is rooted is a low place.
