  Conventionally, this type of planting unit is disclosed, for example, in Patent Document 1 below. FIG. 7 shows a planting unit disclosed in the literature. In the planting unit 51 shown in the figure, support columns 53 and 53 are erected on soil 55 accommodated in a pot 54, and a net body 52 is supported between the support columns 53 and 53. The net body 52 is made of a plastic lattice molded with a mold, and is arranged along a wall surface of a building or a fence. And the young tree of the vine plant S is planted and cultivated in the soil 55 in the pot 54, and the vine of the vine plant S is entangled with the net body 52 and further extended with the growth. A green wall surface is formed by a large number of climbing plants S, S, S,.

Japanese Patent Laid-Open No. 9-205896 (FIG. 1)

  By the way, the climbing plant S grows to a height of 3 to 5 m, for example, in the case of a straw. The climbing plant S grown to such a height is difficult to secure and transport a commodity storage space. Therefore, in the wall greening construction, the pot 54, the columns 53 and 53, the soil 55, and the young plants of the climbing plant S were carried into the construction site and assembled to the planting unit 51 on the site. That is, since the conventional planting unit 51 has to cultivate the vine plant S from the young tree at the construction site, there is a problem that it takes a lot of labor and a long period of time to become a greening wall surface. Such a problem naturally occurs when the green wall is replaced with another one.

  The present invention has been made in view of the above-described conventional problems, and provides a planting unit that is easy to secure and transport a unit storage space and can perform wall greening construction in a short time. Objective.

In order to achieve the above object, the planting unit according to the present invention is bent forward from a rising part for growing a vegetative plant arranged along a wall surface of a building or a fence, and a lower part of the rising part. includes a plastically deformable net member which is formed integrally from the soil receptacle, the soil receptacle 該Ne Tsu DOO body, are the construction of soil vine plants rooted is accommodated.

Also, in the configuration, it nets body, a net base made of synthetic fibers, those which are constituted by a synthetic resin covering the surface of the net base. The synthetic fibers are required to have high durability, and examples of such synthetic fibers include polyester fibers, polyamide fibers, aramid fibers, and vinylon fibers. As the synthetic resin, a resin having a high coating strength that reliably blocks the net base material from the outside when the surface of the net base material is coated is desirable. Examples of such materials include acrylic resin, polyvinyl chloride, polyurethane, SBR (styrene-butadiene rubber), and NBR (nitrile-butadiene rubber).

  And in the said structure, a polyester fiber is used as a synthetic fiber and an acrylic resin is used as a synthetic resin.

Planting unit according to the present invention, the rising part and the soil receiving portion is integrally composed of the nets body, the soil receiving portion, since those containing a soil with climbing plants, a configuration is simple Yes, provided at low cost. In addition, when the rising part is rolled up with a vine plant, the whole unit becomes compact, so it does not take up a large space for display in the store, it is easy to carry, and transportation and construction are easy. In addition, it is possible to deal with soil and nets body and climbing plants together. Therefore, workability on site is good. Moreover, even if the vine plant grown at the rising portion is rolled up together with the rising portion, the stem of the vine plant does not break because the rising portion and the soil receiving portion are integrated. And after construction to a wall surface, there exists an effect that a greening wall surface is completed immediately.

Also, nets body, a net base made of synthetic fibers, if configured by a synthetic resin covering the surface of the net substrate, constitutes a large portion of the net substrate the presence of synthetic fibers, large nets of lightweight tensile strength is provided as a whole. In addition, the synthetic resin that coats the net substrate stabilizes the shape of the synthetic fiber net substrate and isolates it from ultraviolet rays and wind and rain, thus improving the weather resistance and providing a highly durable planting unit. can do. Therefore, the wall surface of the vine plant stable for many years can be held.

Of the synthetic fibers used above, polyester fibers are relatively inexpensive and have high weather resistance. Among the synthetic resins used above, the acrylic resin does not contain chlorine, so it is more environmentally friendly than polyvinyl chloride, has higher weather resistance and water resistance than SBR and NBR, and is cheaper than polyurethane.

The best embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is an external view showing a planting unit according to an embodiment of the present invention, and FIG. 2 is a partial front view showing a part of a net body of the planting unit.
In each figure, the planting unit 1 according to this embodiment includes a net body 2 having a so-called plasticity that can be deformed by hand force and is kept in a deformed shape when the force is removed. This nets body 2 includes a rising portion 3 to be used in an upright, more positive from the lower portion of the rising portion 3 is integrally formed from upwardly songs made soils receptacle 4. Netw The bets body 2 of the soil receiving portion 4 is accommodated soil 5, roots T of vines S is rooted in the soil 5.

Nets body 2 of the can, the surface of the net base 20 is a grid pattern Ojen the textile structure from polyester fibers, is obtained by coating with an acrylic resin 13. In this case, one end 2A of nets body 2 becomes a top end of the rising portion 3, the other end 2B has a tip of the soil receptacle 4. Cell dimensions of nets body 2 is vertical and horizontal 25 mm × 25 mm, for example. Basis weight of the nets body 2 and 350g / m ^2, lighter than the wire mesh. Incidentally, the basis weight of Rene Tsu bets body put the present invention is not particularly limited, it is desirable that in consideration of the strength and weight for example 120~400g / m ² approximately. Further, the nets body 2 due to a large pulling resistance, difficult to remove from the soil the fill end once the soil. On the other hand, polyester fibers used in the nets body 2 is low elongation, tensile strength (product reference intensity) is high and 58kN / m. Incidentally, the tensile strength of the polyester fiber used in the present invention (product reference intensity) is not particularly limited, is about 18~60kN / m to correspond to the basis weight of the nets body as described above.

  The net substrate 20 is knitted using a weft insertion type Russell knitting machine. This raschel knitting machine has loops along the direction of the core of the justified yarn 9 on both sides of the justified yarns 9, 9, 9,... Made of polyester multifilament (11100 decitex (= 10000 total denier)). The knitted yarns 10 and 11 (830 dtex) are knitted so as to advance, and at the same time, the drawn yarn 12A is placed between the chain yarns 10 and 11 from the front side to prevent the loosening of the aligned yarns 9, 9, 9,. A warp 6 is formed by bridging the drawn yarn 12B from the rear side of the bridging, and the intersecting portion 8 of the weft 7 and the warp 6 made of a picked-up yarn (made of polyester multifilament, 11100 dtex) is formed of the chain yarns 10 and 11. The loop is fixed by passing the weft 7 through the loop. In this case, if a multifilament of about 800 to 12000 decitex is used as the polyester fiber constituting the netting yarn 9, the chain yarn 10, the chain yarn 11, the drawn yarns 12 </ b> A and 12 </ b> B and the weft 7 of the net base material 20, it is easy to obtain. It is preferable in terms of inexpensiveness.

  The net base material 20 woven and knitted as described above is immersed under normal temperature and normal pressure in an acrylic resin-water emulsion liquid in which acrylic resin fine particles are dispersed in water by the action of a surfactant. And the net base material 20 pulled up from the acrylic resin-water emulsion liquid is sandwiched between rotating roll pairs, and water is squeezed out so that the acrylic resin-water emulsion liquid is a fine filament of the net base material 20. It reaches every corner and only the required amount remains between the surface of the net substrate 20 and the filaments. The net base material 20 squeezed as described above is subjected to hot air drying at 80 ° C. in a hot air drying facility. Thereby, the water in the acrylic resin-water emulsion liquid is evaporated, and the acrylic resin 13 is solidified in a state where the surface of the net substrate 20 is covered.

Nets body 2 thus resulting is as if like texture plastic grid molded by a die, has a texture, the easy even when leaning against it Sowase the wall surface 17, such as a building collapsed without deformation Do not do. On the other hand, nets body 2 is relatively winding habit force is weak, easy to handle, such as wind or or extended by hand, can be deformed into a desired shape, after deformation remains in its shape. Therefore, the above-described soil receiving portion 4 can also be formed into a free shape by hand force or a folding machine. The shape of the soil receiving portion 4 may be any shape that can receive the soil 5. For example, when viewed from the side, the shape of the soil receiving portion 4 is an arc shape (FIG. 1, FIG. 3, FIG. 4), square box shape, and substantially U shape. It can be formed into a shape, a substantially L shape, a flat dish shape, or the like.

In fabricating the planting unit 1 described above at the factory, it kept suspended like a factory of the beam a rising portion 3 of nets body 2 not a or lift vertically. Then, to accommodate the soil 5 in the soil receiving portion 4 of the nets body 2, cultivating be implanted roots T vine plants S soil 5. After a while, the vine of the climbing plant S is entangled with the rising portion 3, and the climbing plant S grows upward. After the vine plant S has grown sufficiently, when the vine plant S is placed on the inside and the rising portion 3 is arranged on the outside, the rising portion 3 together with the vine plant S is wound forward from one end 2A. The compact planting unit 1 as shown in 3 is obtained as a product. In addition, since the soil 5 in the soil receiving portion 4 is held by being entangled with the root T of the climbing plant S, even if the opening of the soil receiving portion 4 is relatively large, most of the soil 5 does not permeate. It is received in the soil receiving part 4. However, as a precaution, the lower surface of the soil receiving portion 4 may be covered with a soil receiving sheet 14 through which the soil 5 does not pass.

Planting unit 1 configured as described above, the rising portion 3 of nets body 2 since the compact whole defeated with Vine S, it is possible to perform shipping and product display very easily. Thus, since the rising part 3 can be wound and shipped, it becomes compact and can be boxed, so that it can be delivered by courier etc. without selecting a transportation means. Moreover, the rounded planting unit 1 can be conveyed even with a light vehicle, and can be easily delivered to a construction site.
On the other hand, even though rounded climbing plants S as described above, since the integral structure from the rising portion 3 and the soil receiving portion 4 of the nets body 2, at the boundary portion between the rising portion 3 and the soil receiving portion 4 The stem St is not broken or damaged. Incidentally, when the rising portion 3 and the soil receiving portion 4 are separated and independent, even if the rising portion 3 has plasticity, when the rising portion 3 is wound with the vine plant S, the above-mentioned separation position is obtained. The rising portion 3 and the soil receiving portion 4 may be separated from each other or bend greatly, and the stem St or the branches and leaves may be broken or a fatal damage may be caused at that position, and the commercial value of the climbing plant S may be lost.

Then, at the site construction, the earth receiving sheet 14 is removed from the bottom surface of the earth receiving part 4 and the earth receiving part 4 is placed on the earth 16 of the pot 15 installed at the lower part of the wall surface 17 of the building. . At this time, if the other end 2 </ b> B of the soil receiving portion 4 is hung forward from the upper edge of the pot 15, it is convenient when taking out the planting unit 1 or maintaining the soils 5 and 16. Next, nets body 2 of the rising portion 3 and Vine S is raised is if extended linearly, its rear 3A is disposed rising portion 3 so as to accompany the wall surface 17, such as a building or a fence The One end 2A of the rising portion 3 is fixed to the wall surface 17 with a screw or a string. By simply performing such a simple work, the wall greening work is completed, and a green wall is immediately obtained. Therefore, it is possible to save the trouble of planting the climbing plant S from the beginning of the net body and waiting for the growth as in the prior art, and to significantly shorten the construction period.

In planting unit 1 which is the construction as described above, the net base 20 composed of polyester fibers is greater tensile strength, it is lighter than metal nets body. Therefore, it withstands strong winds such as during typhoons. On the other hand, since the acrylic resin 13 as a covering material gives the net base material 20 weather resistance, even if the planting unit 1 is exposed to wind and rain or sunlight, it can be used for a long period of time. Incidentally, high weather resistance and durability is required for the nets body 2. For example, no longer have weathered linen Tsu door body 2 by the use over time, vine plants S, S, S, and the only remaining ..., fueled by strong winds and climbing plants S, S, S, ... The whole may fall apart from the wall surface 17. On the other hand, since the planting unit 1 is flexible as a whole integral is nets 2 and the Vine S, workability in the field well, choose a construction site. Moreover, since the replacement of a new planting unit 1 with climbing plants S it is easy, before reaching the lifetime of the nets body 2 can be replaced with a new planting unit 1.

In the above embodiment, an example is shown in which the net base material 20 knitted by a weft insertion type Russell knitting machine is used, but the present invention is not limited thereto. For example, nets body 2a with net base 20a as shown in FIG. 5 are also included in the nets of the present invention. This nets body 2a, by heating those woven using pull aligned yarns containing low-melting fiber as a weft 7a intersecting the warp threads 6a, and / or該経yarns 6a, each with each warp yarn 6a A net base material 20a is provided in which an intersecting portion 8a with the weft yarn 7a is fused and fixed. The warps 6a, 6a, 6a,... Are arranged at a predetermined interval (for example, 25 mm) in the lateral direction, and the wefts 7a, 7a, 7a,. It has been. The net substrate 20a also, as described above, acrylic resin - immersion in water emulsion liquid, extraction, squeezed liquid, and is in the nets body 2a through each step such hot air drying.

The present invention, as shown in FIG. 6, it is also possible to use nets body 2b that the surface of the net substrate 20b covered with acrylic resin 13 woven in leno weave. Each of the net base materials 20b is woven using warp yarns 6b and weft yarns 7b made of polyester multifilaments, and has a lattice size of 10 mm × 10 mm. The net substrate 20b also, as described above, acrylic resin - immersion in water emulsion liquid, extraction, squeezed liquid, and is in the nets body 2b through each step such hot air drying. Nets body 2b is because a net structure as compared with the above-described nets body 2 is simple, there is an effect that is suppressed manufacturing cost.

In the present invention, the resin for covering the net base material is not limited to the above acrylic resin. For example, when a flameproof function is required, the net base material is immersed in a vinyl chloride resin-water emulsion solution. Alternatively, the surface of the net base material may be covered with a vinyl chloride resin by squeezing a roll and drying at 150 ° C. with hot air.
The nets of the present invention, plastic deformation by hand and folding machines are possible, and is not particularly limited as long as it maintains a shape at that time when not subjected to external force. Namely, nets of the present invention is not limited to those using synthetic fibers and synthetic resins, such as described above, for example, net member made of synthetic fiber alone, the synthetic resin molded net or steel wire net or punched It may be a metal net made of metal or the like.
The vine plant applied to the planting unit of the present invention is not particularly limited as long as it grows long while entwining the surrounding vine, for example, cocoon, kuzu, morning glory, sweet pea, natural cocoon, American Examples include Tsurumasaki and Tsuru Hydrangea.
Moreover, as a raw material of the synthetic resin for coating, for example, a paint type material in which a synthetic resin is dissolved in an organic solvent may be used in addition to the above-mentioned water emulsion type material. It is also possible to add a coloring pigment to the synthetic resin and color it to a desired color. In this case, the use of a dark color pigment further improves the UV resistance.
