Description

  The present invention relates to a wall surface greening unit for greening a wall surface of a structure.

  Conventionally, wall greening has been carried out to plant the walls of buildings and civil engineering structures (structures) for the purpose of alleviating the heat island phenomenon in urban areas, absorbing carbon dioxide in the atmosphere, and creating amenity spaces. Yes.

  And in this kind of wall surface greening system, as disclosed in Patent Document 1, the soil is housed inside a plurality of planting units (wall surface greening units) formed in a pipe shape, and these are planted. A plurality of planting units are held horizontally by a suspension member and connected at a predetermined interval in the vertical direction, and the wire connected to the uppermost planting unit is fed out by a lifting device provided on the roof of the building or There is one in which each planting unit is arranged along the wall of the building by winding.

  Moreover, as shown in Patent Document 2, a frame frame having a plurality of rectangular boxes and a planting base (culture base) accommodated in the plurality of boxes of the frame frame are provided, and the frame is formed by anchor bolts. There is also one in which the frame is fixed to the wall surface of the building and the wall surface is greened by plants vegetated on the planting base in the box.

  Furthermore, as shown in Patent Document 3, a plurality of arms protruding from the outer wall of the building, a plurality of frame members supported by these arms, a net stretched over the frame members, and a lower end side of the frame members It has a plurality of planters placed on the ground along the outer periphery of the building, and the ivy of deciduous plants planted in the planting soil in the planter grows while being supported by the net or frame material provided above And there is also a thing which greened the wall surface of a building.

  However, in the wall surface greening system disclosed in Patent Document 1, a plurality of planting units are suspended in a vertical direction along the wall surface of the building and are juxtaposed for the purpose of feeding and winding the wire with the lifting device provided on the rooftop. In other words, there is a problem that the degree of freedom in design is low, for example, when it is desired to improve the aesthetic appearance by greening an arbitrary position on the wall surface of the building.

  Moreover, since the wall greening system of patent document 2 needs to form the frame frame which accommodates a planting base firmly, it invites high cost, and also in order to fix a frame frame to the wall surface of a building, for example, a building There was a problem that it was not possible to flexibly handle the maintenance of buildings and wall greening systems, such as repainting the walls of objects and replacing the planting base housed in the box of the frame.

  Furthermore, since the wall greening system of Patent Document 3 grows an ivy plant from a planter provided on the ground, the plant for greening is limited, and the degree of freedom in plant selection is low. As in Patent Document 1, there is a problem that the degree of freedom in design is limited.

On the other hand, as shown in FIGS. 6 and 7, a support member 1 is fixed to a wall surface T1 of a building (structure) T, and a wall surface greening unit (greening unit) 2 is installed in a suspended state on the support member 1. Then, there is a wall surface greening system A in which the building T is greened. In this type of wall surface greening system A, the greening unit 2 mixes, for example, soil and an inorganic foam (foam) such as pearlite and heat-bonded fiber, and heat-treats this with steam to make the fiber into soil or foam. The soil base 3 solidified by being entangled with the body is inserted into a mesh frame 4 formed in a bowl shape, and the soil base 3 is held by the mesh frame 4. And the greening unit 2 can be easily installed by hooking the hook part (fixing metal fitting) 5 integrally formed on the mesh frame 4 to the support member 1 or fixing it with bolts and nuts. For this reason, in this wall surface greening system A, the greening unit 2 can be installed at an arbitrary position of the support member 1, the degree of freedom in design and plant selection is high, and the greening unit 2 can be easily removed. Therefore, it is possible to flexibly cope with the maintenance of the building T and the wall surface greening system A (greening unit 2).

  However, in the greening unit 2 of the wall surface greening system A shown in FIGS. 6 and 7, the cultivated soil base 3 is made by tying fibers in soil or foam and solidified, and its strength due to planting. The characteristic (rigidity) is such that the shape can be maintained even when the greening unit 2 is installed on the wall surface T1 of the building T and exposed to wind and rain. Further, the soil foundation 3 formed with such strength characteristics is bent by its own weight when the operator holds it by hand when the greening unit 2 is formed, that is, when the soil foundation 3 is inserted into the mesh frame 4. The handling property (handling property) is poor, and the larger the size of the soil foundation 3 is, the more difficult it is to insert into the mesh frame 4, and there is a problem that much labor is required for the insertion work.

  Moreover, when inserting into the inside of the mesh frame 4, the edge part of the culture foundation | substrate 3 was caught by the mesh frame 4 and the hook part 5 integrally formed in this, and the inconvenience that the damage generate | occur | produced had arisen.

  In view of the circumstances described above, an object of the present invention is to provide a wall surface greening unit that can improve the handleability of a cultivation base, can prevent damage, and can reduce costs.

  In order to achieve the above object, the present invention provides the following means.

  The wall surface greening unit of the present invention is a wall surface greening unit that is supported by a support member fixed to the wall surface of a structure and is installed in a suspended state along the wall surface to green the structure. A soil base on which planting is performed and a fixture for holding the soil base and supporting it in a suspended state on the support member, the soil base including heat-sealing fibers, and heat-treating And the tray that accommodates the heat-sealing culture soil is integrally formed, and the fixture includes a pair of vertical portions and a lateral portion that connects the lower ends of the pair of vertical portions. And is formed in a band shape in a substantially U shape so as to hold the soil foundation by being inserted between the pair of vertical portions.

  Moreover, in the wall surface greening unit of the present invention, it is desirable that the tray is provided with a culture holding protrusion for holding the stored heat-sealing culture soil.

  Furthermore, in the wall surface greening unit of the present invention, it is more desirable that at least the bottom of the tray is formed in a mesh shape.

  In the wall greening unit of the present invention, the soil base is integrally formed by accommodating the heat-sealed soil with low strength characteristics in the tray, so that the strength characteristics can be improved, and the soil base can be handled (handleability). ) Can be improved. And since the strength characteristics of the soil foundation itself are enhanced in this way, the soil foundation is inserted into the mesh frame like a conventional wall greening unit, and the whole soil foundation is wrapped and held by this mesh frame. It is no longer necessary, and it is possible to hold the cultivation base by attaching the cultivation base between the pair of vertical parts by attaching a fixture that is formed in a band shape with a substantially U shape that does not cover the whole cultivation base. By fixing this fixture to a support member fixed on the wall surface and supporting it, the wall surface greening unit (culture base) can be reliably installed along the wall surface of the structure.

  In addition, a substantially U-shaped and belt-like fixing tool can be attached to the soil foundation by a simple operation of inserting the soil foundation between the pair of vertical portions, and the strength characteristics of the soil foundation are enhanced by the tray. Since the heat-sealing culture soil is protected by the tray, it is possible to suitably form the wall surface greening unit without damaging the culture foundation as in the prior art.

  In addition, the heat-sealed soil is contained in the tray and the strength characteristics of the soil foundation itself are enhanced, making it easier to handle the soil foundation during production and transportation, and attaching a fixture to the soil foundation. The handling property of the wall surface greening unit can be improved, and the wall surface greening unit can be easily installed. This makes it possible to improve workability.

  In addition, wall greening with a simple configuration that attaches a belt-like fixture in a substantially U-shape to the cultivation base without using a mesh frame or a hook part (fixing bracket) formed integrally with the mesh frame like a conventional wall greening unit. The unit can be formed, and furthermore, since the tray can also be used as a mold used when producing the soil foundation, it is possible to reduce the cost of the wall greening unit.

  Furthermore, when greening a structure using such a wall greening unit, when replacing the wall greening unit for design changes or maintenance, it is only necessary to replace the cultivation base, and the wall greening system The running cost can be reduced. In other words, in the conventional wall greening unit, the cultivation base is inserted into the mesh frame so that the whole is wrapped, and the plant grows outside the mesh frame from the cultivation base. It is not possible to replace the entire wall greening unit with a new wall greening unit during design changes or maintenance. On the other hand, in the wall surface greening unit of the present invention, the cultivation base is inserted between the pair of vertical portions of the substantially U-shaped belt-shaped fixture, and the cultivation platform is held by the fixture. Can be easily removed by pulling it out of the fixture, and a new wall greening unit can be formed by inserting a new soil base into this fixture.

  In addition, in the wall surface greening unit of the present invention, the tray can be securely integrated with the heat-sealing culture soil by providing a culture-holding projection for holding the stored heat-sealing culture soil in the tray. It becomes possible to improve the handleability (handleability) with certainty and reliably prevent the heat-sealing culture soil from falling off the tray after installation on the wall surface of the structure.

  Furthermore, in the wall surface greening unit of the present invention, the integrity of the tray and the heat-sealing culture soil can be further improved by forming at least the bottom of the tray in a mesh shape. In addition, irrigation can be suitably supplied to and drained from the heat-sealing culture soil contained in the tray, and the water content of the heat-sealing culture soil (culture soil base) is suitable for plant growth. Thus, it is possible to reliably maintain, and it is possible to suitably green the wall surface of the structure.

  Hereinafter, a wall surface greening unit according to an embodiment of the present invention will be described with reference to FIGS. The present embodiment relates to a wall surface greening unit for greening an outer surface and an inner wall surface of a structure such as a building or a civil engineering structure, and a wall surface greening system using the same.

  As shown in FIG. 2 to FIG. 4, the culture foundation 12 is formed in a substantially flat plate shape with a substantially square shape when viewed from the front, and includes a heat fusion fiber and a heat fusion culture soil 14 that is solidified by heat treatment. And a tray 15 that accommodates the heat-sealing medium 14 is integrally formed.

  The heat-sealing medium 14 is formed by mixing soil, an inorganic foam (foam) such as pearlite, and heat-fusible fibers and solidifying them by heat treatment. That is, the heat-sealing culture soil 14 is formed by bonding heat-fusible fibers to each other by heat treatment, or forming a three-dimensional network structure by bonding fibers and foam, and fibers and soil. In addition, the solidified shape is suitably maintained. In the heat-sealed cultivation soil 14 in the solidified state as described above, even when the greening unit 10 is installed on the wall surface T1 of the structure T and the cultivation soil base 12 is exposed to wind and rain, the soil flows out to the outside. It is formed with the strength characteristic of the extent that the shape is maintained over a long period of time. In addition, such a heat-sealing culture soil 14 has a weight per unit volume of the inorganic foam of, for example, 0.5 kg / liter or less, and by mixing this inorganic foam, the weight can be reduced and the plant Appropriate water retention and drainage properties are provided for the growth of rice.

  The tray 15 is formed, for example, in the shape of a plate made of plastic or metal, and includes a substantially flat bottom portion 15a and a side wall portion 15b that gradually inclines outward from the outer peripheral end of the bottom portion 15a toward the upper end of the tray 15. Is formed. Further, the tray 15 of the present embodiment has a bottom portion 15a formed in a mesh shape, and is provided with a plurality of soil holding projections 15c protruding from the bottom portion 15a toward the upper end of the tray 15.

  The tray 15 is filled with the heat-sealing culture medium 14 to form the culture base 12, and at this time, the heat-sealable fibers adhere to the inner surfaces of the bottom 15 a and the side wall 15 b of the tray 15, and the heat-sealing culture medium is formed. 14 and the tray 15 are integrated, and further, the bottom 15a is formed in a mesh shape, and the culture holding protrusions 15c are formed on the bottom 15a. Are securely held together and integrated with each other. The soil foundation 12 of the present embodiment thus formed is compared with the soil foundation 3 of the conventional greening unit 2 (that is, compared with the soil foundation 3 not provided with the tray 15), and the heat-sealing culture soil having low strength characteristics. Since the tray 15 is integrally provided on the outer side of 14, the strength characteristic (rigidity) is enhanced, and the handling property (handleability) is improved.

  In addition, such a cultivation base 12 is filled with a heat fusion cultivation soil 14 in which soil, an inorganic foam and a heat fusion fiber are mixed, and the upper surface of the filled heat fusion cultivation soil 14 is placed on the tray 15. In this state, the heat-sealing culture medium 14 is solidified, and the heat-sealing culture medium 14 and the tray 15 are integrally manufactured. That is, the soil cultivation base 12 of this embodiment can be manufactured by using the tray 15 as a mold.

  In addition, at the stage where the cultivated soil base 12 is formed in this way, for example, seeding directly on the heat-sealed cultivated soil 14, or forming a pit in the heat-sealed cultivated soil 14 and setting a pot seedling in this dent, etc. Applied. In addition, although the plant planted in this heat fusion culture | cultivation soil 14 is preferable, for example, a moss, a sedum, a vine, etc., it does not require limitation.

  On the other hand, the fixture 13 is formed of metal, plastic or the like, and as shown in FIGS. 1 to 3, the pair of vertical portions 13a and 13b and the horizontal portion connecting the lower ends of the pair of vertical portions 13a and 13b. 13c, and is formed in a band shape with a substantially U shape. In addition, the fixture 13 is formed such that the distance between the pair of vertical portions 13a and 13b is equal to or slightly larger than the width of the soil base 12, and one vertical portion 13a is the other vertical portion. It is formed to extend upward from 13b. Furthermore, as shown in FIG. 5, the fixture 13 is attached to the soil foundation 12 by inserting the soil foundation 12 between a pair of vertical portions 13a and 13b. The upper end portion 13d of one vertical portion 13b disposed on the one surface side (a portion extending upward from the other vertical portion 13b) is formed to be disposed above the upper end of the soil culture base 12.

  And in this embodiment, the tree planting unit 10 is configured by attaching one fixing tool 13 to each of both side ends of the soil foundation 12, and as shown in FIG. 1, one vertical portion 13 a of each fixing tool 13. Is fixed to the support member 1 fixed to the wall surface T1 of the structure T, so that the cultivating base 12 is supported by the support member 1 in a suspended state while being held by the fixture 13, and extends along the wall surface T1. Installed. At this time, the plurality of greening units 10 are installed at arbitrary positions on the arbitrary support member 1, that is, installed at arbitrary positions in the vertical direction or the horizontal direction along the wall surface T <b> 1 of the structure T. Thus, it is possible to green the wall T1 of the structure T with a desired design.

  On the other hand, the irrigation tube 11 is, for example, a drip tube in which a plurality of holes for supplying water flowing through the tube to the outside are formed at predetermined intervals. Further, the irrigation tube 11 is guided and arranged in the horizontal direction between the upper end of the cultivation base 12 of the greening unit 10 and the upper support member 1 that supports the greening unit 10. The irrigation tube 11 is connected to a water storage tank that stores water such as tap water and rainwater (not shown), a pump for supplying water in the water storage tank to the irrigation tube 11, and the like. The liquid supplied to the irrigation tube 11 is mixed with liquid fertilizer by supplying liquid fertilizer (liquid fertilizer) into the water storage tank.

  Next, the construction method of the wall surface greening system B having the above configuration will be described, and the operation and effect of the greening unit 10 of the present embodiment will be described.

  When constructing the wall surface greening system B of the present embodiment, first, the support member 1, the cultivating base 12, the fixture 13, and the irrigation tube 11 constituting the greening unit 10 are carried into the field. At this time, the soil base 12 is solidified by heat treatment as described above, and is manufactured by integrally forming the heat-sealing culture soil 14 and the tray 15, and the strength characteristics are enhanced by the tray 15 and heat-sealing. Since the cultivating soil 14 is housed in the tray 15, handling during production (during production) and transportation is easy.

  Next, the carried support member 1 is installed at a predetermined position on the wall surface T1 of the structure T, and a fixing tool 13 is attached to the cultivating base 12 to form the greening unit 10. At this time, in the conventional tree planting unit 2, when the soil base 3 having low strength characteristics is inserted into the mesh frame 4, if the operator holds it with his hand, the soil base 2 bends by his / her own weight, and the handling property ( As the size of the cultivating base 2 is increased, it becomes difficult to insert it into the mesh frame 4 and much labor is required for this insertion work. Moreover, the edge part of the cultivation base 2 was caught by the mesh frame 4 or the hook part 5 integrally formed with this, and the inconvenience that the damage generate | occur | produced had arisen.

  On the other hand, in the greening unit 10 of this embodiment, since the heat-bonding culture soil 14 having low strength characteristics is accommodated in the tray 15 and the strength characteristics of the culture foundation 12 are enhanced, the handling characteristics of the culture foundation 12 are improved. Thus, the fixing work 13 for inserting the soil base 12 between the pair of vertical portions 13a and 13b can be easily performed. Further, since the heat-sealing culture soil 14 is protected by the tray 15 and does not need to be inserted into the mesh frame 4 as in the conventional case, the culture foundation 12 (heat-sealing culture soil 14) is not damaged. Thus, the greening unit 10 is preferably formed.

  And in the stage which formed the greening unit 10 in this way, the greening unit 10 is carried to the installation position according to the design which greens the wall surface T1, and the upper end part 13d of one vertical part 13a of the fixture 13 is attached to the structure T. The greening unit 10 is installed by being fixed to the support member 1 installed on the wall surface T1. At this time, the strength characteristics of the cultivation base 12 are enhanced by accommodating the heat-sealing cultivation soil 14 in the tray 15 with respect to the conventional greening unit 2, so that it is excellent in handling when the greening unit 10 is carried to the installation position. The worker can easily fix the fixture 13 to the support member 1 in a stable state while holding the cultivating base 12 (tray 15).

  Next, the irrigation tube 11 is installed at the stage where the greening unit 10 is installed in a range according to the design. At this time, the irrigation tube 11 is installed by a simple operation of guiding between the upper end of the soil cultivation base 12 of the greening unit 10 and the upper support member 1 supporting the greening unit 10. Construction of the wall greening of the structure T is completed at the stage of installation.

  In such a wall greening system B of this embodiment, when watering a plant planted on the cultivation base 12, the pump is driven by a timer or manually, and the water containing liquid fertilizer in the water storage tank is filled with water. 11 is distributed. And when this water dripped from the several hole of the irrigation tube 11, water and liquid fertilizer are supplied to the cultivation base 12 of the greening unit 10 located below. At this time, the water supplied from the upper end side of the soil foundation 12 is supplied to the heat-sealing culture soil 14 from the mesh bottom 15a of the tray 15 of the culture foundation 12 and the opening portion of the tray 15, and the heat-sealing culture soil. 14 is supplied from the upper end to the lower end (the lower end of the greening unit 10), and surplus water that is not retained by the cultivation base 12 is discharged from the lower end. Thereby, the moisture content of the cultivation base 12 (heat fusion cultivation soil 14) is maintained in a state suitable for the growth of the plant, and the wall surface T1 of the structure T is suitably greened.

  On the other hand, for example, when the greening design of the wall surface T1 of the structure T is desired to be changed or when the greening unit 10 is replaced for maintenance, in the conventional greening unit 2, the cultivating base 3 is inserted into the mesh frame 4 and the whole is wrapped. In rare cases, since the plant grows outside the mesh frame 4 from the culture base 3, the culture base 3 cannot be taken out from the inside of the mesh frame 4. For this reason, the entire greening unit 2 has to be replaced with a new greening unit 2 at the time of design change or maintenance.

  On the other hand, in the greening unit 10 of the present embodiment, the soil foundation 12 is inserted between the pair of vertical portions 13a and 13b of the substantially U-shaped and belt-like fixture 13 so that the soil foundation 12 is located on both side ends. Since it is only held by the fixtures 13 provided one by one, the soil foundation 12 and the fixture 13 are separated by a simple operation of pulling the soil foundation 12 out of the fixture 13. For this reason, design change and maintenance can be performed by inserting a new soil base 12 into the fixture 13 and exchanging only the soil base 12.

  Therefore, in the tree planting unit 10 of the present embodiment, the strength base can be enhanced and the soil base 12 can be improved by integrally forming the soil base 12 with the tray 15 containing the heat-sealing culture soil 14 having low strength characteristics. 12 handling properties can be improved. Thereby, it becomes possible to attach the fixing tool 13 which does not cover the whole cultivation base 12, and hold | maintain the cultivation base 12, and by making this fixing tool 13 be supported by the support member 1 fixed to the wall surface T1. The greening unit 10 (culture base 12) can be installed reliably.

  In addition, the fixture 13 can be attached by a simple operation of inserting the soil base 12 between the pair of vertical portions 13a and 13b, and the strength characteristics of the soil base 12 are enhanced by the tray 15, It is possible to reliably prevent the base 12 from being damaged, and the greening unit 10 can be suitably formed.

  Furthermore, by providing the tray 15, the handling of the cultivation base 12 can be easily performed and the handling of the greening unit 10 is improved, so that the greening unit 10 can be easily installed. It becomes possible to improve workability.

  Further, the greening unit 10 can be formed with a simple configuration in which a substantially U-shaped belt-like fixture 13 is attached to the cultivation base 12, and the tray 15 can also be used as a mold used when the cultivation base 12 is manufactured. The cost of the unit 10 can be reduced.

  In addition, after the greening of the structure T using the greening unit 10, even when design changes or maintenance are performed, it is possible to respond by replacing only the soil cultivation base 12, thus reducing the running cost of the wall greening system B can do.

  In addition, by providing the tray 15 with the culture holding projections 15c for holding the stored thermal fusion culture soil 14, the thermal fusion culture soil 14 and the tray 15 can be integrated with certainty, and handling property is ensured. It becomes possible to improve (handleability) and reliably prevent the heat-sealing culture soil 14 from falling off the tray 15 after being installed on the wall surface T1 of the structure T.

  Furthermore, since the bottom 15a of the tray 15 is formed in a mesh shape, the integrity of the tray 15 and the heat-sealing culture soil 14 can be further improved. Moreover, irrigation can be suitably supplied to the heat-sealing culture soil 14 accommodated in the tray 15 and drainage from the heat-sealing culture soil 14, and the water content of the heat-sealing culture soil 14 (culture soil base 12) is suitable for plant growth. It becomes possible to maintain reliably in the state where it was, and it becomes possible to give greening suitably to the wall surface T1 of the structure T.

  As mentioned above, although embodiment of the wall surface greening unit which concerns on this invention was described, this invention is not limited to said one Embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, in the present embodiment, only the bottom portion 15a of the tray 15 constituting the cultivation base 12 is formed in a mesh shape, but the side wall portion 15b is also formed in a mesh shape so that the tray 15 and thus the cultivation base 12 is configured. You may make it do. In this case, it becomes possible to form the heat-sealing culture soil 14 and the tray 15 more reliably, and furthermore, irrigation to the heat-sealing culture soil 14 and drainage from the heat-sealing culture soil 14 are suitably performed. It becomes possible.

  Further, in this embodiment, the soil holding protrusion 15c is provided on the bottom 15a of the tray 15, but if the heat-sealing culture soil 14 accommodated in the tray 15 can be suitably held, The culture holding protrusion 15c may not be provided, and even if the culture holding protrusion 15c is provided, it may be provided on the side wall portion 15b of the tray 15.

  Further, in this embodiment, the greening unit 10 is configured by attaching the fixtures 13 one by one to the both end sides of the soil foundation 12, but the fixture 13 reliably holds the soil foundation 12.
