Description

本発明は、例えば建物やフェンスなどの壁面をつる性植物で緑化するための植栽ユニットに関するものである。   The present invention relates to a planting unit for greening wall surfaces such as buildings and fences with vine plants.

従来、この種の植栽ユニットは例えば下記の特許文献１に開示されている。かかる文献開示の植栽ユニットを図７に示す。図に示した植栽ユニット５１では、ポット５４内に収容された土５５に支柱５３,５３が立設され、これらの支柱５３,５３間にネット体５２が支持されている。ネット体５２は金型で成型されたプラスチック製格子から成っており、建物やフェンスなどの壁面に添って配置される。そして、つる性植物Ｓの幼木がポット５４内の土５５に植えられて栽培され、生長とともにつる性植物Ｓのつるがネット体５２に絡みついて更に伸長する。このように伸長した多数のつる性植物Ｓ，Ｓ，Ｓ，・・・で緑化壁面が形成されるようになっている。   Conventionally, this type of planting unit is disclosed, for example, in Patent Document 1 below. Such a planting unit disclosed in the literature is shown in FIG. 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,.

特開平９−２０５８９６号公報（図１）Japanese Patent Laid-Open No. 9-205896 (FIG. 1)

ところで、つる性植物Ｓは、例えば蔦の場合３〜５ｍの高さに生長する。かかる高さまで生長したつる性植物Ｓは商品保管スペースの確保や輸送が困難である。そのため、壁面緑化施工にあたっては、ポット５４、支柱５３，５３、土５５、つる性植物Ｓの幼木を施工現場へ搬入し現地で前記の植栽ユニット５１に組み立てていた。すなわち、従来の植栽ユニット５１は、施工現場でつる性植物Ｓを幼木から栽培しなければならないために、緑化壁面となるまでに栽培の手間と長期間がかかるという問題があった。かかる問題は緑化壁面を別のものに替える際にも当然ながら生じる。   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.

本発明は、上記した従来の問題点に鑑みてなされたものであって、ユニット保管スペースの確保や輸送が容易で、壁面緑化施工を簡単かつ短時間に行なうことのできる植栽ユニットの提供を目的とする。   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.

上記目的を達成するために、本発明に係る植栽ユニットは、建物やフェンスなどの壁面に添って配置されるつる性植物生長用の立上り部と、立上り部の下部から前向きに曲成された土受容部とから一体に構成された可塑性ネット体を備え、該可塑性ネット体の土受容部に、つる性植物が根づいた土が収容された構成にしてある。   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. A plastic net body integrally formed with the soil receiving portion is provided, and the soil receiving portion of the plastic net body is configured so that the soil rooted in the climbing plant is accommodated.

また、前記構成において、可塑性ネット体が、合成繊維で形成されたネット基材と、該ネット基材の表面を被覆した合成樹脂とを備えて構成されているものである。前記の合成繊維としては耐久性の高いものが要求されるが、かかるものとしては、例えばポリエステル繊維、ポリアミド繊維、アラミド繊維、ビニロン繊維などが挙げられる。前記の合成樹脂としては、ネット基材の表面を被覆したときにネット基材を外部から確実に遮断し且つ被膜強度の高いものが望ましい。かかるものとしては、例えばアクリル樹脂、ポリ塩化ビニル、ポリウレタン、ＳＢＲ（スチレン−ブタジエンゴム）、ＮＢＲ（ニトリル−ブタジエンゴム）などが挙げられる。   Moreover, the said structure WHEREIN: The plastic net body is comprised including the net base material formed with the synthetic fiber, and the synthetic resin which coat | covered the surface of this net base material. 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).

そして、前記構成において、合成繊維としてポリエステル繊維を用い、合成樹脂としてアクリル樹脂を用いたものである。   And in the said structure, a polyester fiber is used as a synthetic fiber and an acrylic resin is used as a synthetic resin.

本発明に係る植栽ユニットは、立上り部および土受容部から一体構成にされた可塑性ネット体の、土受容部に、つる性植物付きの土を収容したものであるので、構成が簡素であり安価に提供される。また、立上り部をつる性植物とともに丸めるとユニット全体がコンパクトになるので、店舗での展示の際に広い場所をとらず、持ち運びしやすく、輸送、施工が楽である。加えて、土と可塑性ネット体とつる性植物を一体に取り扱うことができる。従って、現場での施工性がよい。また、立上り部で生長したつる性植物を立上り部とともに丸めても立上り部と土受容部が一体であるために、つる性植物の茎などが折れたりしない。そして、壁面への施工後は、直ちに、緑化壁面が完成するという効果がある。   The planting unit according to the present invention has a simple structure because the soil with the vine plant is accommodated in the soil receiving portion of the plastic net body integrally formed from the rising portion and the soil receiving portion. Provided at low cost. In addition, when the rising part is rolled up with a vine plant, the whole unit becomes compact, so it is easy to carry around and easy to transport and install, without taking up a large space for display at the store. In addition, soil, a plastic net body, and a climbing plant can be handled integrally. 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.

また、可塑性ネット体が、合成繊維で形成されたネット基材と、該ネット基材の表面を被覆した合成樹脂とを備えて構成されている場合は、ネット基材の大部分を構成する合成繊維の存在により、全体として軽量で引張り強度の大きな可塑性ネット体が提供される。また、ネット基材を被覆する合成樹脂は合成繊維製のネット基材の形状を安定させるとともに、紫外線や風雨から隔離するので耐候性が向上し、延いては耐久性の高い植栽ユニットを提供することができる。従って、長年にわたり安定したつる性植物の壁面を保持することができる。   Further, when the plastic net body is composed of a net base material formed of synthetic fibers and a synthetic resin covering the surface of the net base material, the synthetic material constituting the majority of the net base material The presence of the fiber provides a plastic net body that is light in weight and high in tensile strength 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.

前記で使用する合成繊維のうち、ポリエステル繊維は比較的安価で耐候性が高い。また、前記で用いる合成樹脂のうち、アクリル樹脂は塩素を含んでいないのでポリ塩化ビニルよりも環境にやさしく、ＳＲＢ、ＮＢＲよりも耐候性および耐水性が高く、ポリウレタンよりも安価で済む。   Of the synthetic fibers used above, polyester fibers are relatively inexpensive and have high weather resistance. Of the synthetic resins used above, acrylic resin does not contain chlorine, so it is more environmentally friendly than polyvinyl chloride, has higher weather resistance and water resistance than SRB and NBR, and is cheaper than polyurethane.

本発明の最良の実施形態を図面に基づいて説明する。尚、以下に述べる実施形態は本発明を具体化した一例に過ぎず、本発明の技術的範囲を限定するものでない。ここに、図１は本発明の一実施形態に係る植栽ユニットを示す外観図、図２は前記植栽ユニットのネット体の一部分を示す部分正面図である。
各図において、この実施形態に係る植栽ユニット１は、手の力により変形可能で、力を抜くと変形後の形のまま保たれる、いわゆる可塑性を有するネット体２を備えている。この可塑性ネット体２は、立てた状態で使用される立上り部３と、立上り部３の下部から前向きに更には上向きに曲成された土受容部４とから一体に構成されている。可塑性ネット体２の土受容部４には土５が収容され、この土５につる性植物Ｓの根Ｔが根づいている。 The best mode for carrying out 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. The plastic net body 2 is integrally formed from a rising portion 3 that is used in a standing state and a soil receiving portion 4 that is bent forward and further upward from a lower portion of the rising portion 3. The soil 5 is accommodated in the soil receiving portion 4 of the plastic net body 2, and the root T of the sexual plant S is rooted in the soil 5.

前記の可塑性ネット体２は、ポリエステル繊維で格子状に織編した織編組織であるネット基材２０の表面を、アクリル樹脂１３で被覆したものである。この場合、可塑性ネット体２の一端２Ａは立上り部３の上端となり、他端２Ｂは土受容部４の先端となっている。可塑性ネット体２の格子寸法は例えば縦横２５ｍｍ×２５ｍｍである。可塑性ネット体２の目付量は３５０ｇ／ｍ2と、金網と比べて軽い。尚、本発明における可塑性ネット体の目付量は特に限定されないが、強度および軽量化を考慮すると例えば１２０〜４００ｇ／ｍ2程度であることが望ましい。また、可塑性ネット体２は引き抜き抵抗が大きいために、端部をいったん土中に埋めると土から抜き取りにくい。一方、可塑性ネット体２に用いたポリエステル繊維は低伸度であり、引張り強度（製品基準強度）が５８ｋＮ／ｍと高い。尚、本発明に用いるポリエステル繊維の引張り強度（製品基準強度）は特に限定されないが、上記した可塑性ネット体の目付量に対応すると１８〜６０ｋＮ／ｍ程度となる。 The plastic net body 2 is obtained by coating the surface of a net base material 20 which is a woven or knitted structure woven and knitted with polyester fibers with an acrylic resin 13. In this case, one end 2 </ b> A of the plastic net body 2 is the upper end of the rising portion 3, and the other end 2 </ b> B is the tip of the soil receiving portion 4. The lattice size of the plastic net body 2 is, for example, 25 mm × 25 mm in length and width. The basis weight of the plastic net body 2 is 350 g / m 2 , which is light compared to the wire net. The basis weight of the plastic net body in the present invention is not particularly limited, but is preferably about 120 to 400 g / m 2 in view of strength and weight reduction. Moreover, since the plastic net body 2 has a large pull-out resistance, it is difficult to remove the plastic net body 2 from the soil once the end portion is buried in the soil. On the other hand, the polyester fiber used for the plastic net body 2 has a low elongation and a tensile strength (product standard strength) as high as 58 kN / m. The tensile strength (product standard strength) of the polyester fiber used in the present invention is not particularly limited, but is about 18 to 60 kN / m corresponding to the basis weight of the plastic net body described above.

ネット基材２０は緯糸挿入式のラッセル編機を用いて編織成されている。このラッセル編機は、ポリエステルマルチフィラメント（１１１００デシテックス（＝１００００トータルデニール））製のひき揃え糸９，９，９，・・・の両側に、ひき揃え糸９の糸芯方向に沿ってループが進むように鎖糸１０，１１（８３０デシテックス）をそれぞれ編成し、同時にひき揃え糸９,９，９，・・・のバラケを防止するために鎖糸１０，１１間に前側から絞り糸１２Ａを架け渡し後側から絞り糸１２Ｂを架け渡すことにより経糸６を形成し、ひき揃え糸（ポリエステルマルチフィラメント製、１１１００デシテックス）から成る緯糸７と経糸６との交差部分８は鎖糸１０，１１のループに緯糸７を通すことにより固定するようにしている。この場合、ネット基材２０のひき揃え糸９、鎖糸１０、鎖糸１１、絞り糸１２Ａ，１２Ｂ、緯糸７を構成するポリエステル繊維として、約８００〜１２０００デシテックスのマルチフィラメントを使用すると、入手容易、安価な点で好ましい。   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 yarn 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 because of its low cost.

上記のように織編成されたネット基材２０はアクリル樹脂微粒子を界面活性剤の作用により水中に分散させて成るアクリル樹脂−水エマルジョン液中に常温常圧下で浸漬される。そして、アクリル樹脂−水エマルジョン液から引き上げられたネット基材２０は、回転するロール対に挟まれて水などが搾り出されることにより、アクリル樹脂−水エマルジョン液がネット基材２０の微細なフィラメント間の隅々に行き渡り、必要量だけがネット基材２０の表面およびフィラメント間に残る。前記のように搾られたネット基材２０は熱風乾燥設備において８０℃で熱風乾燥に付される。これにより、アクリル樹脂−水エマルジョン液中の水が蒸散し、アクリル樹脂１３がネット基材２０の表面を被覆した状態で固化する。   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.

こうして出来上がった可塑性ネット体２は、あたかも金型により成型されたプラスチック製格子のような質感、手触りを有し、建物などの壁面１７に添わせて立て掛けた場合でも容易には変形せず崩れ落ちたりしない。他方で、可塑性ネット体２は比較的巻癖力が弱く、手で延ばしたり巻いたりするなどの取り扱いが容易であり、自由な形状に変形することができ、変形後はその形に留まる。従って、上記した土受容部４も手の力や折り曲げ機により自由な形に成形することができる。かかる土受容部４の形状は土５を受けられる形状であればよく、例えば側面から見て、上面が開口した、円弧状（図１、図３、図４）、角箱状、略Ｕ字状、略Ｌ字状、平皿状などに形成することができる。   The resulting plastic net body 2 has a texture and feel like a plastic lattice molded by a mold, and even if it is leaned against a wall 17 such as a building, it does not easily deform and collapses. do not do. On the other hand, the plastic net body 2 has a relatively weak winding force, is easy to handle such as extending or winding by hand, can be deformed into a free shape, and remains in that shape after deformation. 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, substantially U-shape It can be formed into a shape, a substantially L shape, a flat dish shape, or the like.

上記した植栽ユニット１を工場で製作するにあたっては、まず可塑性ネット体２の立上り部３を垂直に持ち上げて工場の梁などに懸架しておく。そして、可塑性ネット体２の土受容部４に土５を収容し、土５につる性植物Ｓの根Ｔを植え込んで栽培する。しばらくすると、つる性植物Ｓのつるが立上り部３に絡みつき、つる性植物Ｓが上向きに生長する。つる性植物Ｓが十分生長したのちに、つる性植物Ｓを内側に配し立上り部３を外側に配した状態で、つる性植物Ｓもろともに立上り部３を一端２Ａから前方へ巻くと、図３に示したようなコンパクトな植栽ユニット１が商品として得られる。尚、土受容部４内の土５はつる性植物Ｓの根Ｔに絡んで保持されているため、土受容部４の目開きが比較的大きくても、ほとんどの土５は透過することなく土受容部４内に収受されている。但し、念のために、土受容部４の下面を、土５が通過しない土受シート１４で被っておくとよい。   In manufacturing the planting unit 1 described above at the factory, the rising portion 3 of the plastic net body 2 is first lifted vertically and suspended on a beam of the factory. And the soil 5 is accommodated in the soil receiving part 4 of the plastic net body 2, and the root T of the sexual plant S hanging on the soil 5 is planted and cultivated. 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.

上記した構成の植栽ユニット１は、可塑性ネット体２の立上り部３をつる性植物Ｓとともに丸ごと巻けてコンパクトになるので、出荷や商品陳列を極めて容易に行なうことができる。このように、立上り部３を巻いて出荷できることにより、コンパクトになって箱詰めが可能となるため、輸送手段を選ぶことなく宅配便などで配送することも可能である。また、丸めた植栽ユニット１は軽車両でも搬送することができ、簡便に施工現場に届けることができる。
一方で、前記のようにつる性植物Ｓを丸めたとしても、可塑性ネット体２の立上り部３と土受容部４とは一体構成なので、立上り部３と土受容部４との境界部分で茎Ｓｔが折れたり傷んだりしない。因みに、立上り部３と土受容部４が分離独立のものであると、例え立上り部３が可塑性を有していたとしても、立上り部３をつる性植物Ｓとともに巻くと、前記の分離位置で立上り部３と土受容部４とが離間したり大きく屈曲してその位置で茎Ｓｔや枝葉が折れたり致命的な傷が付くことがあり、つる性植物Ｓの商品価値が無くなるおそれがある。 Since the planting unit 1 having the above-described configuration can be rolled up together with the hanging plant S along the rising portion 3 of the plastic net body 2 to be compact, shipping and product display can be performed 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 or the like 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 if the climbing plant S is rounded as described above, the rising portion 3 and the soil receiving portion 4 of the plastic net body 2 are integrated, so that the stalk is formed at the boundary portion between the rising portion 3 and the soil receiving portion 4. St will not break or be 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.

そして、現場施工の際には、土受容部４の底面から土受シート１４が取り除かれ、建物の壁面１７の下部に設置されているポット１５の土１６上に、土受容部４が置かれる。このとき、土受容部４の他端２Ｂをポット１５の上縁から前方へ垂れ下げておくと、植栽ユニット１を取り出す際や、土５，１６の整備の際に便利である。次に、可塑性ネット体２の立上り部３およびつる性植物Ｓが直線状に展ばされて立ち上げられ、その背面３Ａが建物やフェンスなどの壁面１７に添うように立上り部３が配置される。立上り部３の一端２Ａはビスや紐などで壁面１７に固定される。このような簡単な作業を行なうだけで壁面緑化施工が完了し、直ちに、緑化壁面が得られる。従って、従来技術のようにつる性植物Ｓをネット体に一から植栽して生長を待つ手間が省け、工期の大幅な短縮化を図ることができる。   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, the rising portion 3 of the plastic net body 2 and the climbing plant S are straightly spread and raised, and the rising portion 3 is arranged so that the back surface 3A thereof follows a wall surface 17 such as a building or a fence. . 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.

上記のように施工された植栽ユニット１において、ポリエステル繊維から成るネット基材２０は引張り強度が大きく、金属製の可塑性ネット体よりも軽量である。従って、台風時などの強風にも耐える。一方、被覆材たるアクリル樹脂１３はネット基材２０に耐候性を持たせるので、植栽ユニット１が風雨や日光に曝されても長期間の使用が可能となる。因みに、可塑性ネット体２には高い耐候性と耐久性が要求される。例えば、経時使用により可塑性ネット体２が風化して無くなり、つる性植物Ｓ,Ｓ,Ｓ,・・・だけが残ったとすると、強風に煽られてつる性植物Ｓ,Ｓ,Ｓ,・・・全体が壁面１７から離れて倒れることがある。他方で、植栽ユニット１は可塑性ネット体２とつる性植物Ｓが一体化し全体として柔軟性があるので、現場での施工性がよく、施工場所を選ばない。また、つる性植物Ｓ付きの新たな植栽ユニット１との交換は容易であるので、可塑性ネット体２の寿命に達する前に、新たな植栽ユニット１と交換することができる。   In the planting unit 1 constructed as described above, the net base material 20 made of polyester fibers has a large tensile strength and is lighter than a metal plastic net 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, the plastic net body 2 is required to have high weather resistance and durability. For example, if the plastic net body 2 is weathered and lost by use over time, and only the vine plants S, S, S,... Remain, the vine plants S, S, S,. The whole may fall apart from the wall surface 17. On the other hand, since the plastic net body 2 and the vine plant S are integrated and flexible as a whole, the planting unit 1 has good workability at the site and does not select a construction site. Moreover, since replacement | exchange with the new planting unit 1 with the vine plant S is easy, before reaching the lifetime of the plastic net body 2, it can replace | exchange with the new planting unit 1.

For example, a plastic net body 2a using a net base material 20a as shown in FIG. 5 is also included in the plastic net body of the present invention. The warp 6a and / or the weft 7a intersecting with the warp 6a and / or the weft 7a woven by using a line-up yarn including a low melting point fiber are heat-treated to thereby produce the warp 6a and each weft 7a. A net base material 20a in which a crossing portion 8a is fused and fixed is provided. 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. As described above, the net base material 20a is also made into a plastic net body 2a through respective steps such as immersion in an acrylic resin-water emulsion liquid, extraction, liquid squeezing, and hot air drying.

また、本発明は、図６に示すように、からみ織りで織成したネット基材２０ｂの表面をアクリル樹脂１３で被覆した可塑性ネット体２ｂを用いることも可能である。ネット基材２０ｂは、いずれも、ポリエステル製のマルチフィラメントから成る経糸６ｂと緯糸７ｂを用いて織成され、格子寸法は縦横１０ｍｍ×１０ｍｍである。このネット基材２０ｂも、既述のように、アクリル樹脂−水エマルジョン液への浸漬、取り出し、液搾り、および、熱風乾燥といった各工程を経て可塑性ネット体２ｂにされる。可塑性ネット体２ｂは既述の可塑性ネット体２と比べてネット構造が簡素であるため、製造コストを安価に抑えられるという効果がある。   In the present invention, as shown in FIG. 6, it is also possible to use a plastic net body 2b in which the surface of a net base material 20b woven by leno weave is covered with an acrylic resin 13. 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. As described above, the net base material 20b is also made into the plastic net body 2b through respective steps such as immersion in an acrylic resin-water emulsion liquid, extraction, liquid squeezing, and hot air drying. Since the plastic net body 2b has a simple net structure as compared with the above-described plastic net body 2, there is an effect that the manufacturing cost can be suppressed at a low cost.

そして、本発明において、ネット基材を被覆する樹脂としては上記のアクリル樹脂に限らず、例えば防炎機能が要求される場合は、ネット基材を塩化ビニル樹脂−水エマルジョン液中に浸漬して、ロール搾り、１５０℃熱風乾燥を施し、ネット基材の表面を塩化ビニル樹脂で被覆するようにしてもよい。
本発明の可塑性ネット体としては、手や折り曲げ機で塑性変形が可能であり、且つ、外部から力を受けないときはそのときの形状を保っているものであれば特に限定されない。すなわち、本発明の可塑性ネット体は既述したような合成繊維および合成樹脂を用いたものに限らず、例えば、合成繊維単体から成るネット体、合成樹脂成型ネット、あるいは、鋼線ネットやパンチングメタルなどから成る金属製のネット体であっても構わない。
本発明の植栽ユニットに適用される、つる性植物としては、周囲につるを絡めながら長く生長していくものであれば特に限定されないが、例えば、蔦、葛、アサガオ、スイートピー、自然薯、アメリカつるまさき、つるあじさいなどが挙げられる。
また、被覆用の合成樹脂の原料としては、上記した水エマルジョンタイプのもの以外に、例えば有機溶剤に合成樹脂を溶解させた塗料タイプのものを用いても構わない。そして、合成樹脂に着色顔料を添加して所望の色に着色することも可能である。その場合に濃色顔料を用いると、耐紫外線能がいっそう向上する。 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. It is also possible to squeeze the roll and dry it with hot air at 150 ° C. to coat the surface of the net base material with a vinyl chloride resin.
The plastic net body of the present invention is not particularly limited as long as it can be plastically deformed with a hand or a bending machine and can maintain the shape at that time when it is not subjected to external force. That is, the plastic net body of the present invention is not limited to those using synthetic fibers and synthetic resins as described above. For example, a net body made of a synthetic fiber alone, a synthetic resin molding net, a steel wire net, or a punching metal It may be a metal net body made of 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. And it is also possible to add a color pigment to a synthetic resin and color it to a desired color. In this case, the use of a dark pigment further improves the UV resistance.
