Description

本発明は、構造物の壁面に緑化を施すための壁面緑化ユニットに関する。   The present invention relates to a wall surface greening unit for greening a wall surface of a structure.

従来、都市部におけるヒートアイランド現象の緩和や大気中の炭酸ガスの吸収、アメニティ空間の創出などを目的として、建築物や土木構造物（構造物）の壁面に植栽を施す壁面緑化が行なわれている。   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.

そして、この種の壁面緑化システムには、特許文献１に開示されるように、パイプ状に形成した複数の植栽ユニット（壁面緑化ユニット）の内部に土壌を収容して植栽を施し、これら複数の植栽ユニットを、吊り部材によって水平に保持しつつ上下方向に所定の間隔をあけて繋ぎ、最上部の植栽ユニットに接続したワイヤーを、建築物の屋上に設けた昇降装置で繰出しあるいは巻取ることで、各植栽ユニットを建築物の壁面に沿って配置するようにしたものがある。   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.

また、特許文献２に示されるように、複数の方形状の箱を備えたフレーム枠と、このフレーム枠の複数の箱に収容される植栽基盤（培土基盤）とを備え、アンカーボルトでフレーム枠を建築物の壁面に固定し、箱内の植栽基盤に植生した植物によって壁面に緑化を施すようにしたものもある。   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.

さらに、特許文献３に示されるように、建築物の外壁から突出した複数の腕木と、これら腕木に支持された複数のフレーム材と、フレーム材に架張したネットと、フレーム材の下端側の建築物の外周に沿う地上に置かれた複数のプランターとを備え、プランター内の植栽土壌に植栽した落葉蔓性植物のツタが上方に設けたネットやフレーム材に支持されながら生育することで、建築物の壁面に緑化を施すようにしたものもある。   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.

しかしながら、特許文献１の壁面緑化システムでは、屋上に設けた昇降装置でワイヤーの繰出しや巻上げを行なう関係上、複数の植栽ユニットを建築物の壁面に沿って垂直方向に吊り下げて並設させることになり、建築物の壁面の任意の位置を緑化して美的外観を向上させたい場合などデザイン面の自由度が低いという問題があった。   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.

また、特許文献２の壁面緑化システムは、植栽基盤を収容するフレーム枠を堅牢に形成する必要があるため、コスト高を招き、しかも、フレーム枠を建築物の壁面に固定するため、例えば建築物の壁面を塗り替えたり、フレーム枠の箱内に収容した植栽基盤を交換するなど、建築物や壁面緑化システムのメンテナンスに柔軟に対応できないという問題があった。   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.

さらに、特許文献３の壁面緑化システムは、地上に設けたプランターからツタ植物を生育させて緑化を施すものであるため、緑化を施すための植物に限りがあり、植物選定の自由度が低いうえ、特許文献１と同様、デザイン面の自由度にも限りがあるという問題があった。   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.

一方、図６及び図７に示すように、建築物（構造物）Ｔの壁面Ｔ１に支持部材１を固設し、この支持部材１に壁面緑化ユニット（緑化ユニット）２を吊り下げ状態で設置して、建築物Ｔに緑化を施すようにした壁面緑化システムＡがある。この種の壁面緑化システムＡにおいては、緑化ユニット２が、例えば土壌とパーライトなどの無機質発泡体（発泡体）と熱融着繊維を混合し、これを蒸気で加熱処理して熱融着繊維を土壌や発泡体に絡ませ固形化した培土基盤３を、篭状に形成したメッシュ枠４の内部に挿入し、このメッシュ枠４で培土基盤３を保持するようにして形成されている。そして、メッシュ枠４に一体形成した引掛部（固定金具）５を支持部材１に引っ掛けたり、ボルトとナットで固定するなどして、緑化ユニット２を簡便に設置することができる。このため、この壁面緑化システムＡにおいては、支持部材１の任意の位置に緑化ユニット２を設置することができ、デザインや植物選定の自由度が高く、また、緑化ユニット２の取り外しが容易であるため、建築物Ｔや壁面緑化システムＡ（緑化ユニット２）のメンテナンスに柔軟に対応することが可能である。
特開２００４−２４８５５０号公報 特開２００２−９５３４７号公報 特開２００２−３４３５０号公報 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).

しかしながら、図６及び図７に示した壁面緑化システムＡの緑化ユニット２において、培土基盤３は、熱融着繊維を土壌や発泡体に絡ませて固形化したものであり、植栽を施す関係上、その強度特性（剛性）が緑化ユニット２を建築物Ｔの壁面Ｔ１に設置した後に風雨にさらされてもその形状を維持できる程度とされている。そして、このような強度特性で形成した培土基盤３は、緑化ユニット２の形成時に、すなわち培土基盤３をメッシュ枠４の内部に挿入する際に、作業者が手で持つと自重によって曲がるなどし、ハンドリング性（取扱性）が悪く、培土基盤３のサイズが大きくなるほどにメッシュ枠４の内部に挿入しにくくなって、挿入作業に多大な労力を要するという問題があった。   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.

また、メッシュ枠４の内部に挿入する際に、培土基盤３の端部がメッシュ枠４やこれに一体形成した引掛部５に引っ掛かって千切れ、損傷が生じるという不都合が生じていた。   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.

本発明は、上記事情に鑑み、培土基盤の取扱性を向上させるとともに、損傷を防止することを可能にし、且つ低コスト化を図ることが可能な壁面緑化ユニットを提供することを目的とする。   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.

上記の目的を達するために、この発明は以下の手段を提供している。   In order to achieve the above object, the present invention provides the following means.

本発明の壁面緑化ユニットは、構造物の壁面に固設した支持部材に支持されて前記壁面に沿って吊り下げ状態で設置することにより前記構造物に緑化を施す壁面緑化ユニットであって、植栽が施される培土基盤と、該培土基盤を保持して前記支持部材に吊り下げ状態で支持させるための固定具とを備え、前記培土基盤は、熱融着繊維を含み、加熱処理することで固形化する熱融着培土内に、プラスチック繊維を絡ませてシート状に形成した芯材を配して形成され、前記固定具は、一対の縦部と該一対の縦部の下端同士を繋ぐ横部とを備え、前記一対の縦部の間に差し込むことで前記培土基盤を保持するように略Ｕ字状で帯状に形成されていることを特徴とする。   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.

本発明の壁面緑化ユニットにおいては、熱融着繊維を含み、加熱処理することで固形化する熱融着培土内に、プラスチック繊維を絡ませてシート状に形成した芯材を配して培土基盤を形成することによって、従来の壁面緑化ユニットの培土基盤と比較し、強度特性を高めることができ、培土基盤のハンドリング性（取扱性）を向上させることができる。そして、このように、培土基盤自体の強度特性が高められていることによって、従来の壁面緑化ユニットのようにメッシュ枠に培土基盤を挿入し、このメッシュ枠で培土基盤の全体を包んで保持する必要がなくなり、培土基盤の全体を覆うことのない略Ｕ字状で帯状に形成した固定具を、一対の縦部の間に培土基盤を差し込んで取り付けて培土基盤を保持することが可能になり、この固定具を壁面に固設した支持部材に固定して支持させることで確実に壁面緑化ユニット（培土基盤）を構造物の壁面に沿って設置することが可能になる。   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.

また、略Ｕ字状で帯状の固定具を、この一対の縦部の間に培土基盤を差し込むという簡易な操作で培土基盤に取り付けることができ、且つ培土基盤の強度特性が芯材によって高められているため、従来のように培土基盤が損傷するようなことをなくして、好適に壁面緑化ユニットを形成することが可能になる。   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.

さらに、培土基盤自体の強度特性が高められていることで、培土基盤の生産時や運搬時の取扱いが容易になるとともに、培土基盤に固定具を取り付けた壁面緑化ユニットのハンドリング性を向上させることができ、壁面緑化ユニットの設置を容易に行うことが可能になる。これにより、施工性の向上を図ることが可能になる。   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.

また、従来の壁面緑化ユニットのようにメッシュ枠やこれに一体形成した引掛部（固定金具）を用いることなく、培土基盤に略Ｕ字状で帯状の固定具を取り付けるというシンプルな構成で壁面緑化ユニットを形成できるため、壁面緑化ユニットの低コスト化を図ることが可能になる。   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. Since the unit can be formed, the cost of the wall surface greening unit can be reduced.

さらに、このような壁面緑化ユニットを用いて構造物に緑化を施した場合には、デザイン変更やメンテナンスのために壁面緑化ユニットを交換する際に、培土基盤のみを交換すればよく、壁面緑化システムのランニングコストを低減することが可能になる。すなわち、従来の壁面緑化ユニットでは、培土基盤がメッシュ枠に挿入されて全体が包まれ、培土基盤から植物がメッシュ枠の外側に生育しているため、メッシュ枠の内部から培土基盤を取り出すことができず、デザイン変更やメンテナンス時に、壁面緑化ユニット全体を新たな壁面緑化ユニットと交換せざるを得ない。これに対し、本発明の壁面緑化ユニットにおいては、略Ｕ字状で帯状の固定具の一対の縦部の間に培土基盤を差し込んで、培土基盤が固定具に保持されているため、培土基盤を固定具から引き抜くことで容易に取り外すことができ、新たな培土基盤をこの固定具に差し込むことで、新たな壁面緑化ユニットを形成することができる。   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.

以下、図１から図５を参照し、本発明の一実施形態に係る壁面緑化ユニットについて説明する。本実施形態は、建築物や土木構造物などの構造物の外面や内面の壁面に緑化を施すための壁面緑化ユニット及びこれを用いた壁面緑化システムに関するものである。   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.

本実施形態の壁面緑化システムＢは、図１に示すように、構造物Ｔの壁面Ｔ１に固設されるとともに、上下方向に所定の間隔をあけて並設された複数の支持部材１と、支持部材１に支持され、上下方向に隣り合う一対の支持部材１の間に配された複数の壁面緑化ユニット（緑化ユニット）１０と、支持部材１と緑化ユニット１０の間に配された灌水チューブ（灌水部材）１１とが主な構成要素とされている。   As shown in FIG. 1, the wall surface greening system B of the present embodiment is fixed to the wall surface T1 of the structure T, and a plurality of support members 1 that are arranged in parallel at a predetermined interval in the vertical direction, A plurality of wall surface greening units (greening units) 10 supported by the support member 1 and disposed between a pair of support members 1 adjacent in the vertical direction, and an irrigation tube disposed between the support member 1 and the greening unit 10 The (irrigation member) 11 is a main component.

支持部材１は、例えばＣ型チャンネルなどのチャンネルであり、断面略凹状に形成されている。また、支持部材１は、開口部側を上方に向けた状態で、且つ対向する一対の側壁部のうち一方の側壁部の外面を構造物Ｔの壁面Ｔ１に面接触させた状態で、一方の側壁部をアンカーボルトなどで壁面Ｔ１に固定して設けられている。さらに、複数の支持部材１は、それぞれ、水平方向に延設されて平行に設置されている。また、本実施形態において、支持部材１の一方の側壁部と対向する他方の側壁部の外面側には、すなわち構造物Ｔの壁面Ｔ１に対して外側に位置する側壁部の外面側には、この外面から外側に突出する例えばビスやボルトなどが支持部材１の延設方向に所定の間隔をあけて設けられている。   The support member 1 is a channel such as a C-shaped channel, for example, and has a substantially concave cross section. Further, the support member 1 is in a state in which the opening side is directed upward, and the outer surface of one of the pair of opposing side wall portions is in surface contact with the wall surface T1 of the structure T. The side wall is fixed to the wall T1 with an anchor bolt or the like. Furthermore, each of the plurality of support members 1 extends in the horizontal direction and is installed in parallel. Further, in the present embodiment, on the outer surface side of the other side wall portion facing one side wall portion of the support member 1, that is, on the outer surface side of the side wall portion positioned outside the wall surface T1 of the structure T, For example, screws and bolts protruding outward from the outer surface are provided at a predetermined interval in the extending direction of the support member 1.

一方、本実施形態の緑化ユニット１０は、図２及び図３に示すように、植栽が施される培土基盤１２と、培土基盤１２を保持して支持部材１に吊り下げ状態で支持させるとともに、保持した培土基盤１２を構造物Ｔの壁面Ｔ１に沿って設置するための固定具１３とを備えて構成されている。   On the other hand, as shown in FIG. 2 and FIG. 3, the greening unit 10 of the present embodiment holds the cultivating base 12 to be planted and the cultivating base 12 and supports the supporting member 1 in a suspended state. The holding base 12 is provided with a fixture 13 for installing the cultivated soil base 12 along the wall surface T1 of the structure T.

培土基盤１２は、図２から図４に示すように、正面視略正方形状で略平板状に形成されており、熱融着繊維を含み、加熱処理することで固形化する熱融着培土１４内に、プラスチック繊維を絡ませてシート状に形成した芯材１５を配して形成されている。また、本実施形態において、熱融着培土１４は、土壌とパーライトなどの無機質発泡体（発泡体）と熱融着性繊維を混合したものであり、蒸気で加熱処理することによって熱融着性繊維同士が接着したり、繊維と発泡体、繊維と土壌が接着することで三次元の網状構造が形成され、これにより、土壌が保持されるとともに固形化した形状が好適に保持される。そして、このように固形化した状態の熱融着培土１４は、緑化ユニット１０を構造物Ｔの壁面Ｔ１に設置し、培土基盤１２が風雨にさらされた場合においても、土壌が外部に流出するようなことがなく、その形状が長期にわたって保持される程度の強度特性を備えて形成されている。また、このような熱融着培土１４は、無機質発泡体の単位体積当りの重量が例えば０．５ｋｇ／リットル以下とされ、この無機質発泡体が混在することによって、軽量化が図られるとともに、植物の生育に対する適度な保水性と排水性が付与されている。   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. The core material 15 formed in the shape of a sheet with plastic fibers entangled therein is arranged. 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.

また、本実施形態の培土基盤１２においては、幅方向略中央の熱融着培土１４内にシート状の芯材１５が設けられており、加熱処理した際に、熱融着培土１４の熱融着性繊維が芯材１５のプラスチック繊維に接着することで、芯材１５と熱融着培土１４が一体形成される。そして、このように芯材１５が熱融着培土１４と一体になることで、本実施形態の培土基盤１２は、従来の緑化ユニット２の培土基盤３と比較し（すなわち芯材１５を備えていない培土基盤３と比較し）、強度特性（剛性）が高められ、ハンドリング性（取扱性）の向上が図られている。   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.

なお、加熱処理して培土基盤１２を形成した段階で、例えば培土基盤１２に直接播種したり、培土基盤１２に窪みを形成しこの窪みにポット苗を設置するなどして植栽が施される。また、この培土基盤１２に植栽される植物は、例えばコケ、セダム、蔓性植物などが好ましいが特に限定を必要としない。   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.

固定具１３は、金属やプラスチック等で形成されるとともに、図１から図３、及び図５に示すように、一対の縦部１３ａ、１３ｂとこれら一対の縦部１３ａ、１３ｂの下端同士を繋ぐ横部１３ｃとを備えて略Ｕ字状で帯状に形成されている。また、固定具１３は、一対の縦部１３ａ、１３ｂの間隔が培土基盤１２の幅と同等あるいは培土基盤１２の幅よりも僅かに大きく形成されるとともに、一方の縦部１３ａが他方の縦部１３ｂよりも上方に延出して形成されている。さらに、固定具１３は、図５に示すように、一対の縦部１３ａ、１３ｂの間に培土基盤１２を差し込むことで培土基盤１２に取り付けられ、このように取り付けた状態で、培土基盤１２の一面１２ａ側に配された一方の縦部１３ａの上端部１３ｄ（他方の縦部１３ｂよりも上方に延出した部分）が培土基盤１２の上端よりも上方に配されるように形成されている。   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. .

そして、本実施形態において、緑化ユニット１０は、培土基盤１２の両側端側にそれぞれ一つずつ固定具１３を取り付けて構成され、図１に示すように、各固定具１３の一方の縦部１３ａの上端部１３ｄを構造物Ｔの壁面Ｔ１に固設した支持部材１に固定することによって、培土基盤１２が固定具１３に保持されつつ支持部材１に吊り下げ状態で支持され、壁面Ｔ１に沿うように設置される。また、このとき、複数の緑化ユニット１０を、任意の支持部材１の任意の位置に設置することで、すなわち構造物Ｔの壁面Ｔ１に沿って上下方向や水平方向の任意の位置に設置することによって、構造物Ｔの壁面Ｔ１に所望のデザインの緑化を施すことが可能になる。   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.

一方、灌水チューブ１１は、例えばチューブ内を流通する水を外部に供給するための複数の孔が所定の間隔をあけて形成されたドリップチューブとされている。また、この灌水チューブ１１は、緑化ユニット１０の培土基盤１２の上端とこの緑化ユニット１０を支持する上方の支持部材１の間に水平方向に誘導されて配置されている。また、灌水チューブ１１には、図示せぬ例えば水道水や雨水などの水を貯留する貯水槽や、灌水チューブ１１に貯水槽内の水を供給するためのポンプなどが接続されている。なお、灌水チューブ１１に供給される水には、貯水槽内に液体肥料（液肥）を供給するなどして液肥が混入されている。   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.

ついで、上記の構成からなる壁面緑化システムＢの施工方法を説明するとともに、本実施形態の緑化ユニット１０の作用及び効果について説明する。   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.

本実施形態の壁面緑化システムＢを施工する際には、はじめに、支持部材１、緑化ユニット１０を構成する培土基盤１２や固定具１３、灌水チューブ１１などを現場に搬入する。このとき、培土基盤１２は、前述のように、加熱処理によって固形化され、熱融着培土１４と芯材１５を一体形成して製作され、この芯材１５によって強度特性が高められているため、製作時（生産時）や運搬時の取り扱いが容易である。   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.

ついで、搬入した支持部材１を構造物Ｔの壁面Ｔ１の所定位置に設置するとともに、培土基盤１２に固定具１３を取り付けて緑化ユニット１０を形成する。このとき、従来の緑化ユニット２においては、強度特性の低い培土基盤３をメッシュ枠４の内部に挿入する際に、作業者が手で持つと自重によって培土基盤３が曲がるなどし、ハンドリング性（取扱性）が悪く、培土基盤３のサイズが大きくなるほどにメッシュ枠４の内部に挿入しにくくなり、この挿入作業に多大な労力を要していた。また、培土基盤３の端部がメッシュ枠４やこれに一体形成した引掛部５に引っ掛かって千切れ、損傷が生じるという不都合が生じていた。   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.

これに対し、本実施形態の緑化ユニット１０においては、強度特性の低い熱融着培土１４内にプラスチック繊維を絡ませた芯材１５が熱融着培土１４と一体に設けられて、培土基盤１２の強度特性が高められているため、培土基盤１２のハンドリング性が向上し、一対の縦部１３ａ、１３ｂの間にこの培土基盤１２を差し込む固定具１３の取付作業が容易に行える。また、このように培土基盤１２の強度特性が高められ、且つ従来のようにメッシュ枠４の内部に挿入する必要がないため、培土基盤１２に損傷が生じることなく固定具１３の取付作業が行え、好適に緑化ユニット１０が形成される。   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.

そして、このように緑化ユニット１０を形成した段階で、壁面Ｔ１を緑化するデザインに応じた設置位置に緑化ユニット１０を運び、固定具１３の一方の縦部１３ａの上端部１３ｄを構造物Ｔの壁面Ｔ１に設置した支持部材１に固定して、緑化ユニット１０を設置する。このとき、従来の緑化ユニット２に対し、培土基盤１２自体の強度特性が高められ、且つ軽量化が図られているため、緑化ユニット１０を設置位置に運ぶ際のハンドリング性に優れ、作業員が培土基盤１２を持って安定した状態で容易に、固定具１３の支持部材１への固定作業を行える。   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.

ついで、デザインに応じた範囲に緑化ユニット１０を設置した段階で、灌水チューブ１１を設置する。このとき、緑化ユニット１０の培土基盤１２の上端と緑化ユニット１０を支持する上方の支持部材１の間を通し誘導するという簡易な操作により灌水チューブ１１が設置され、このように、灌水チューブ１１を設置した段階で構造物Ｔの壁面緑化の施工が完了する。   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.

また、本実施形態の壁面緑化システムＢにおいて、培土基盤１２に植栽した植物に灌水を行なう際には、タイマーや手動によってポンプを駆動するとともに、貯水槽内の液肥を含む水が灌水チューブ１１を流通する。そして、灌水チューブ１１の複数の孔からこの水が滴下することにより、下方に位置する緑化ユニット１０の培土基盤１２の上端側から水と液肥が供給される。培土基盤１２の上端側から供給された水は、培土基盤１２の上端から下端（緑化ユニット１０の下端）側に供給されてゆき、培土基盤１２に保水されない余剰水が下端から排出される。これにより、培土基盤１２の水分量が植物の生育に適した状態で維持され、構造物Ｔの壁面Ｔ１に好適に緑化が施される。   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.

一方、例えば構造物Ｔの壁面Ｔ１の緑化デザインを変更したい場合やメンテナンスのために緑化ユニット１０を交換する場合、従来の緑化ユニット２では、培土基盤３がメッシュ枠４に挿入されて全体が包まれ、且つ培土基盤３から植物がメッシュ枠４の外側に生育しているため、メッシュ枠４の内部から培土基盤３を取り出すことが困難である。このため、デザイン変更やメンテナンス時に、緑化ユニット２全体を新たな緑化ユニット２と交換せざるを得なかった。   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.

これに対し、本実施形態の緑化ユニット１０においては、略Ｕ字状で帯状の固定具１３の一対の縦部１３ａ、１３ｂの間に培土基盤１２を差し込み、培土基盤１２が両側端側にそれぞれ一つずつ設けた固定具１３で保持されているに過ぎないため、培土基盤１２を固定具１３から引き抜くという簡易な操作によって、培土基盤１２と固定具１３が分離される。このため、この固定具１３に新たな培土基盤１２を差し込んで、培土基盤１２のみを交換することで、デザイン変更やメンテナンスが行える。   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.

したがって、本実施形態の緑化ユニット１０においては、熱融着繊維を含み、加熱処理することで固形化する熱融着培土１４内に、プラスチック繊維を絡ませてシート状に形成した芯材１５を配して培土基盤１２を形成することによって、強度特性を高めることができ、培土基盤１２のハンドリング性を向上させることができる。これにより、培土基盤１２の全体を覆うことのない固定具１３を取り付けて培土基盤１２を保持することが可能になり、この固定具１３を壁面Ｔ１に固設した支持部材１に支持させることで確実に緑化ユニット１０（培土基盤１２）を設置できる。   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.

また、固定具１３を、一対の縦部１３ａ、１３ｂの間に培土基盤１２を差し込むという簡易な操作で取り付けることができ、且つ培土基盤１２の強度特性が芯材１５によって高められているため、培土基盤１２が損傷することを確実に防止でき、好適に緑化ユニット１０を形成することが可能になる。   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.

さらに、培土基盤１２の製作時や運搬時の取扱いが容易になり、且つ緑化ユニット１０のハンドリング性が向上することで、緑化ユニット１０の設置を容易に行うことが可能になり、施工性の向上を図ることが可能になる。   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.

また、培土基盤１２に略Ｕ字状で帯状の固定具１３を取り付けるというシンプルな構成で緑化ユニット１０を形成できるため、緑化ユニット１０の低コスト化を図ることが可能になる。   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.

さらに、緑化ユニット１０を用いて構造物Ｔに緑化を施した後、デザイン変更やメンテナンスを行う場合においても、培土基盤１２のみを交換することで対応できるため、壁面緑化システムＢのランニングコストを低減することができる。   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.

以上、本発明に係る壁面緑化ユニットの実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。例えば、本実施形態では、培土基盤１２の両側端側にそれぞれ一つずつ固定具１３を取り付けて緑化ユニット１０が構成されているものとしたが、固定具１３は、確実に培土基盤１２を保持しつつ吊り下げ状態で支持させることができれば、取付位置や取付数を限定する必要はない。   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.
