Description

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

  Conventionally, wall greening has been performed by planting 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 any 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 a heat-fusible fiber, and heat-treats this with steam to produce the heat-fusible fiber. The soil base 3 solidified by entangled with soil or foam is inserted into the 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 formed by entangled the heat-sealing fibers with soil or foam, and is planted. The strength characteristic (rigidity) is such that the shape can be maintained even after being exposed to wind and rain after the greening unit 2 is installed on the wall surface T1 of the building T. 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 In the heat-sealing medium that is solidified in the above, a core material formed in the form of a sheet by entwining plastic fibers is arranged, and the fixture connects the pair of vertical portions and the lower ends of the pair of vertical portions. It is characterized by being formed in a strip shape in a substantially U shape so as to hold the cultivating base by being inserted between the pair of vertical portions.

  In the wall surface greening unit of the present invention, a culture base is formed by arranging a core material formed in a sheet shape with plastic fibers entangled in a thermal fusion culture medium containing heat-bonded fibers and solidified by heat treatment. By forming it, it is possible to enhance the strength characteristics and improve the handleability (handleability) of the soil base compared to the soil base of the conventional wall greening unit. 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.

  The U-shaped and belt-shaped fixture 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 core material. Therefore, it is possible to suitably form the wall surface greening unit without damaging the soil cultivation base as in the prior art.

  In addition, the strength characteristics of the soil foundation itself are enhanced, making it easier to handle the soil foundation during production and transportation, and improving the handling of the wall greening unit with a fixture attached to the soil foundation. Therefore, it becomes possible to easily install the wall surface greening unit. This makes it possible to improve workability.

Since the unit can be formed, the cost of the wall surface greening unit can be reduced.

  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 and the whole is wrapped, and the plant grows outside the mesh frame from the cultivation base, so that the cultivation base can be taken out from the inside of the mesh frame. 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.

  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.

Further, in the present embodiment, the heat-sealing culture soil 14 is a mixture of soil and an inorganic foam (foam) such as pearlite and heat-fusible fibers, and heat-fusible by heat treatment with steam. A three-dimensional network structure is formed by adhering fibers to each other, or adhering fibers and foam, and fibers and soil, whereby the solid shape is suitably retained while the soil is retained. 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.

  Moreover, in the cultivation base 12 of this embodiment, the sheet-like core material 15 is provided in the thermal fusion cultivation soil 14 in the substantially center in the width direction, and the thermal fusion of the thermal fusion cultivation soil 14 is performed when heat treatment is performed. Adhesive fibers are bonded to the plastic fibers of the core material 15 so that the core material 15 and the heat-sealing medium 14 are integrally formed. And since the core material 15 is united with the heat fusion cultivation soil 14 in this way, the cultivation foundation 12 of this embodiment is compared with the cultivation foundation 3 of the conventional greening unit 2 (that is, the core material 15 is provided). Strength characteristics (rigidity) are improved, and handling (handling) is improved.

  In addition, at the stage where the cultivating base 12 is formed by heat treatment, for example, seeding is directly performed on the cultivating base 12, or a pit is formed in the cultivating base 12 and pot seedlings are placed in the pit. . Moreover, although the plant planted on this soil base 12 is preferably moss, sedum, vine plant, etc., there is no particular limitation.

  The fixture 13 is formed of metal, plastic, or the like, and connects the pair of vertical portions 13a and 13b and the lower ends of the pair of vertical portions 13a and 13b as shown in FIGS. 1 to 3 and FIG. It is provided with a horizontal portion 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 13a disposed on the one surface 12a side (the portion extending upward from the other vertical portion 13b) is formed to be disposed above the upper end of the cultivating 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 foundation 12 is solidified by heat treatment as described above, and is manufactured by integrally forming the heat-sealing culture soil 14 and the core material 15, and the strength characteristics are enhanced by the core material 15. Easy to handle during production (production) and transportation.

  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 greening 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 / her hand, the soil base 3 bends due to his / her own weight. As the size of the cultivating base 3 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 3 was caught by the mesh frame 4 and the hook part 5 integrally formed with this, and the inconvenience that the damage arises occurred.

  On the other hand, in the greening unit 10 of the present embodiment, a core material 15 entangled with plastic fibers in the heat-sealing culture soil 14 having low strength characteristics is provided integrally with the heat-sealing culture soil 14, and Since the strength characteristics are enhanced, the handling property of the soil base 12 is improved, and the fixing work 13 for inserting the soil base 12 between the pair of vertical portions 13a and 13b can be easily performed. Further, the strength characteristics of the soil foundation 12 are enhanced in this way, and since there is no need to insert the inside of the mesh frame 4 as in the conventional case, the fixing work 13 can be attached without causing damage to the soil foundation 12. 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, since the strength characteristics of the soil cultivation base 12 itself are enhanced and lighter than the conventional greening unit 2, the handling property when the greening unit 10 is transported to the installation position is excellent. The fixing tool 13 can be easily fixed to the support member 1 in a stable state with the soil foundation 12.

  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.

  Moreover, in the wall surface greening system B of this embodiment, when watering the plant planted on the cultivation base 12, the pump is driven by a timer or manually, and water containing liquid fertilizer in the water storage tank is filled with the water irrigation tube 11. Circulate. And when this water dripped from the several hole of the irrigation tube 11, water and liquid fertilizer are supplied from the upper end side of the cultivation base 12 of the greening unit 10 located below. The water supplied from the upper end side of the cultivation base 12 is supplied from the upper end to the lower end (lower end of the greening unit 10) side of the cultivation base 12, 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 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. Rarely, since the plant grows outside the mesh frame 4 from the culture base 3, it is difficult to take out the culture base 3 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, a design change and maintenance can be performed by inserting a new cultivating base 12 into the fixture 13 and exchanging only the cultivating base 12.

  Therefore, in the greening unit 10 of the present embodiment, the core material 15 that is formed in a sheet shape with the plastic fibers entangled in the heat-sealing medium 14 that includes heat-sealing fibers and is solidified by heat treatment is disposed. By forming the cultivating base 12, strength characteristics can be enhanced, and the handling ability of the cultivating base 12 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.

  Moreover, since the fixing tool 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 core material 15, It is possible to reliably prevent the cultivation base 12 from being damaged, and the greening unit 10 can be suitably formed.

  Furthermore, the handling of the cultivating base 12 is facilitated during handling and transportation, and the handling of the greening unit 10 is improved, so that the greening unit 10 can be easily installed and the workability is improved. Can be achieved.

  Moreover, since the greening unit 10 can be formed with a simple configuration in which the substantially U-shaped and belt-like fixture 13 is attached to the cultivation base 12, the cost of the greening 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.

  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, it is assumed that the greening unit 10 is configured by attaching the fixtures 13 one by one to both side ends of the soil foundation 12, but the fixture 13 securely holds the culture foundation 12. However, if it can be supported in a suspended state, there is no need to limit the attachment position and the number of attachments.
