Description

  The present invention relates to a green wall structure.

  From the viewpoint of environmental improvement and energy saving, buildings such as factories and schools are required to have green walls along with rooftop greening, and some proposals have been made as green wall structures. For example, in Patent Document 1, a porous climbing aid and a net-like protective material are arranged on a standing surface such as a wall surface at a predetermined interval, and an adsorbing vine plant such as hedera is climbed between them. It describes a technique for greening the wall surface by growing it. As a climbing aid for porous materials, foamed resin bodies, coconut shell fibers, and the like are used.

  Patent Document 2 describes a technique in which a multipurpose greening board in which a planting pot is embedded in a main body filled with soil is used for a greening method, and FIG. 12 and FIG. 15 show the multipurpose greening board as a vertical wall surface. And a green wall structure is described.

  The greening wall structure of the aspect which arrange | positions a porous climbing aid to a wall surface as described in patent document 1, and grows while climbing a plant there is long for a plant to grow while climbing It takes days. For this reason, when the plant is not yet grown, sunlight directly hits the porous climbing aid over a long period of time, and a sufficient heat insulating effect cannot be obtained. Moreover, as maintenance when the plant has withered, it is necessary to remove almost the entire surface and start over. For this reason, there is still a point to be improved as a construction method for greening a large-scale wall, particularly a wall having a high height in the vertical direction.

  As described in Patent Document 2, the method of attaching a multi-purpose greening board embedded with a planting pot to a vertical wall surface to green the wall surface can complete the greening of the wall surface at the time of installation, regardless of the scale. You can finish the greening by the required period. However, in the case of large-scale wall greening, it takes a lot of time and labor to attach each multipurpose greening board to the wall, and a large number of parts are also required to install them. Furthermore, when a multipurpose greening board is attached using a support, the entire multipurpose greening board is attached to the front side of the support, but it is inevitable that the space corresponding to the thickness of the support becomes a useless space. .

  The present invention has been made in view of the circumstances as described above, and can be constructed at a low cost and in a short number of days regardless of the size of the area required for greening, and a wasteful space is generated. It is an object of the present invention to provide a green wall structure that can cover the entire surface that needs greening in a short number of days with plants while avoiding as much as possible.

  The greening wall structure according to the present invention basically comprises at least a greening unit comprising two or more struts, a car member and a vegetation sandbag contained in the car member, and the greening unit includes a plurality of greening units. It is characterized in that the pieces are attached between the columns in a posture in which a part protrudes from the front surface of the column, and an irrigation pipe is arranged on the upper part of the cage member in each greening unit.

  In the greening wall structure according to the present invention, a surface that needs to be greened is covered with a plurality of greening units, and each greening unit needs to be greened only by its own area with a plant, such as a wall surface. The greening by the greening plant can be completed in a short number of days in the entire area or in the area where the greening is necessary. In addition, it is possible to plant different types of plants in each greening unit, and it is also possible to construct a greening wall structure with high design. In addition, when plant wilt or the like occurs in a specific greening unit, only the greening unit needs to be replaced, and maintenance costs can be reduced.

  When constructing, it is only necessary to install each greening unit by using upright posts, and the work is easy, and each greening unit is attached between the uprights with a part protruding from the front of the post. In addition, a part of the greening unit also enters the space corresponding to the thickness of the column, thereby reducing the waste of space.

  In addition, irrigation pipes are arranged above the cage members in each tree planting unit, so that water can be reliably supplied to the vegetation sandbags contained in each cage member, so that the growth of the planted plants progresses smoothly. To do.

  In one aspect of the greening wall structure according to the present invention, the vegetation sandbag that constitutes the greening unit is accommodated in the car member in a state that it can cover all or part of the front surface of the support column. In this aspect, since the upright pillar can be covered with the vegetation sandbag bag and further with the greening plant growing from the sac bag, a greening wall structure having no sense of incongruity in design can be obtained.

  In the greening wall structure according to the present invention, the shape and size of the vegetation sandbag that constitutes the greening unit is arbitrary as long as it is accommodated in the car member, and is not particularly limited. However, it is a preferable aspect that the vegetation sandbag is an elongated, substantially cylindrical shape. By being elongated and substantially cylindrical, a plurality of vegetation sandbags can be stably housed in a cage member in a state of being stacked in a horizontal orientation, and an oblique upper surface of each vegetation sandbag that is housed. It is possible to prevent the soil from being inadvertently leaked from the opening by providing an opening in the plant and planting a plant or a plant planted with the plant there.

  In the green wall structure of the above form, preferably, the vegetation sandbag is housed in the car member in a state where it cannot be freely moved by being deformed itself. In this aspect, the weight of the greening plant planted in the vegetation sandbag can prevent the vegetation sandbag from rotating downward in the cage member. It is possible to more reliably prevent the soil from inadvertently leaking from the opening formed in the above.

  In the greening wall structure according to the present invention, the bag constituting the vegetation sandbag needs to have appropriate air permeability and water permeability as well as required strength. Examples of the material used for the bag include a nonwoven fabric and a woven fabric made of a resin material. As an example of a bag body using a nonwoven fabric, a sheet (for example, “Warifu manufactured by Nippon Steel Plast Co., Ltd.”) is produced by continuously laminating and heat-sealing stretch-reinforced polyolefin resin split fibers vertically and horizontally. "(Trade name)) in a bag shape by sewing or heat fusion, or a sheet made by spraying molten polyester-related resin into long fibers (for example," Appeal "(trade name) manufactured by Unitika) Examples thereof include those formed into a bag shape by sewing or heat fusion. In addition, examples of the bag body using a woven fabric include a sheet made by weaving resin fibers, which is formed into a bag shape by sewing or heat fusion, and an example of a sheet made by weaving resin fibers. For example, Kureray Trading Co., Ltd. “Cremona Kansui” (Vinylon) (trade name), “Econonet Karugaru” (drawn polyethylene) (trade name), Toyobo Co., Ltd. Sheet "(made of polyester) (trade name), and the like.

  In the greening wall structure according to the present invention, preferably, the sac constituting the vegetation sandbag is provided with a function of preventing the root of the plant from extending. In this aspect, it is possible to prevent the roots of the greening plant from jumping out of the bag body constituting the vegetation sandbag bag and entering the adjacent vegetation sandbag bag. Can be performed. Thereby, a greening method is also possible in which different types of plants are grown for each vegetation sandbag and a green wall structure with a high design is constructed. Specific examples of the bag in this case include, for example, a bag made of a woven or non-woven fabric that is particularly fine as described above, and an agent that suppresses root elongation, such as Priventol (trade name: manufactured by Bayer). A bag body soaked with can be exemplified.

  In the greening wall structure according to the present invention, the vegetation soil accommodated in the vegetation sandbag is arbitrary and is not particularly limited. However, from the viewpoint of ease of work when manufacturing the greening unit and attaching it to the support, it is preferably a lightweight artificial soil including a lightweight material. In lightweight artificial soil, the main materials are gravelly soil containing air bubbles created by digging up old volcanic gravel layers, etc. Examples include pulverized waste materials and water purification plant sludge. Lightweight main materials include obsidian perlite, nacreous pearlite, and a pulverized product of synthetic resin foam. In the green wall structure according to the present invention, the vegetation soil is accommodated in a vegetation sandbag. Therefore, even if the lightweight main material floats on the surface side of the soil or the lightweight artificial soil, it will not flow out of the vegetation sandbag and be lost. Therefore, on the condition that there is no hindrance to plant growth, a large amount of the lightweight main material can be mixed into the soil or the lightweight artificial soil. Thereby, further weight reduction of the vegetation sandbag is possible.

  In addition, in order to add water retention and breathability to the vegetation soil contained in the vegetation sandbag, a porous material such as coconut shell fibers, wood chips, straw, and a foamed polyurethane sponge pulverized product In addition, pulverized products of foamed polyphenol, porous ceramic chips, etc. may be blended, and as a nutrient, compost purified from bark, cow dung, chicken dung, pig dung, etc. and appropriate chemical fertilizer are blended May be.

  The greening wall structure according to the present invention can also be constructed along the wall surface of an existing building. In that case, the said support | pillar is erected along the wall surface of the existing building. The support may be fixed directly to the wall of the building, or a simple foundation may be made along the wall and erected there. It can also be constructed as a green wall structure that is independent of existing buildings. In that case, make a solid foundation and stand upright there. When constructing as an independent greening wall structure, it is possible to attach greening units to both sides of the support column, and it is possible to obtain a greening wall structure with higher design.

  ADVANTAGE OF THE INVENTION According to this invention, the greening wall structure which can cover the whole surface which needs greening in a short number of days with a plant can be obtained, avoiding a useless space as much as possible.

  Hereinafter, the greening wall structure by this invention is demonstrated based on embodiment.

  As shown in FIG. 1A and FIG. 2, the greening wall structure A basically includes two or more struts 1 erected at a predetermined interval, and a greening unit 2 attached to the strut 1. Consists of. The column 1 is erected on an appropriate foundation 11 (see FIG. 2) along a wall (not shown) of a building such as a school or factory. It may be erected and constructed as an independent building without being along the wall of the building.

  In the illustrated example, the support columns 1 are erected at intervals of about 2 to 3 m, and H-shaped steel is used as the support columns 1. An appropriate steel material such as L-shaped steel, C-shaped steel, or prismatic steel can be used for the support column 1 on the condition that it has a required strength. Not only steel materials but wooden pillars or reinforced resin pillars may be used.

  The greening unit 2 includes a car member 3 and a vegetation sandbag 4 that is accommodated in the car member 3. The greening unit 2 can be made by an arbitrary procedure. Hereinafter, an example will be described with reference to FIGS. As shown in FIG. 3, the cage member 3 basically has a metal wire 31 having a diameter of about 3 to 4 mm, preferably a corrosion-resistant or corrosion-resistant metal wire 31 spaced vertically and horizontally by about 15 cm. It is formed by weaving or welding. In this example, the car member 3 has a U-shaped cross section as a whole with the upper part opened. The height may be about 400 to 600 mm. Further, the lateral width a on the front side of the car member 3 is substantially equal to the distance between the centers of the upright columns 1 and 1, and the lateral width b on the back side is slightly narrower than the lateral width a on the front side. The width is such that it can pass between the columns 1 and 1. Further, an appropriate number (two in the figure) of first L-shaped steel 32 is welded to the bottom surface of the car member 3 such that the vertical piece 33 is positioned at a substantially intermediate position in the front-rear direction of the car member 3. Has been.

  The car member 3 is attached between the columns 1 and 1. The attachment method may be arbitrary. In the illustrated example, a second L-shaped steel 12 for supporting the car member 3 from below is attached in a horizontal direction between adjacent struts by appropriate means such as welding or screwing. In addition, when the car member 3 is attached, a fixing plate 13 is attached to a place where the upper portion of the car member 3 is located by appropriate means such as welding or screwing.

  When attaching the car member 3, the rear side of the car member 3 whose width is narrow is sent through the space between the adjacent struts 1, 1 into the space between the struts 1, 1 and then attached to the bottom surface of the car member 3. The vertical piece 33 of the first L-shaped steel 32 is dropped so as to be in contact with the back side of the second L-shaped steel 12 attached between the columns 1 and 1. As a result, the car member 3 is positioned between the support columns 1 and 1 in a posture in which a part of the car member 3 protrudes from the front side of the support columns 1 and 1. Further, in this state, both end portions on the front side of the car member 3 are positioned at substantially the center of each column 1.

  After the car member 3 is positioned as described above, the vegetation sandbag 4 having the shape shown in FIG. 6 is accommodated in the car member 3. The overall shape of the vegetation sandbag 4 is arbitrary. Although it may be rectangular, it is preferably substantially cylindrical as shown. The vegetation sandbag 4 includes a bag body 41 and soil or lightweight artificial soil 42 housed therein. The bag body 41 is made, for example, by stitching a woven fabric or a nonwoven fabric made of a resin material into a cylindrical shape, and has appropriate air permeability and water permeability. Preferably, the bag body 41 is fine-grained or impregnated with a drug that suppresses root elongation, and the root of the greening plant P can be prevented from penetrating the bag body 4 and extending to the outside. Like that. The lightweight artificial soil 42 is composed of a main material such as gravel soil and a light main material such as perlite. Appropriate nutrients for the planting plant P may be blended.

  In the example shown in the drawing, the longitudinal width of the substantially cylindrical vegetation sandbag 4 is substantially the same as the center distance between the columns 1 and 1 (that is, the lateral width a on the front side of the car member 3). The diameter of the car member 3 is slightly larger than the width in the front-rear direction. When the vegetation sandbag 4 is housed in the car member 3, as shown in FIG. 4, both ends are crushed into a somewhat flat posture. Thereby, the vegetation sandbag 4 is pushed into the car member 3 in a posture in which the flattened portion is inserted between the front surface of the car member 3 and the front surface of the support column 1 and in a horizontal position. It is. Thereby, the half area | region of the surface side of the support | pillar 1 is covered with the vegetation sandbag 4. In addition, as described above, the diameter of the vegetation sandbag 4 is slightly larger than the width of the car member 3 in the front-rear direction, so that the vegetation sandbag 4 inserted into the car member 3 and the wall surface of the car member 3 The vegetation sandbag 4 is in a state where it cannot move freely.

  Similarly, a required number of vegetation sandbag bags 4 are accommodated in the car member 3. This state is shown in FIG. In the figure, four vegetation sandbags 4 are accommodated, but the number of accommodation is determined by the depth of the car member 3 and the diameter (thickness) of the vegetation sandbags 4 and takes into consideration the working environment and the like. To select as appropriate.

  Next, the end 34 of the vertical member on the back side of the car member 3 containing the vegetation sandbag 4 is bent inward, and using this, the car member 3 is an upper part of the car member 3, the car A third L-shaped steel 35 is attached to a region protruding from the front surface of 1. Further, a fourth L-shaped steel 36 is attached to the upper portion of the car member 3 at a position close to the fastening plate 13 attached to the support column, and the fourth L-shaped steel 36 and the fastening plate 13 are connected. Secure with bolts and nuts. Accordingly, one of the greening units 2 including the car member 3 and the vegetation sandbag 4 housed in the car member 3 is attached between the support columns 1 and 1. In the following, the required number of greening units 2 are attached in multiple stages in the vertical direction of the support, and more than one in the horizontal direction. In FIG. 2, the greening unit 2 is attached in three stages in the vertical direction of the support column 1, but the number of stages is not limited.

  Thereafter, the irrigation pipe 5 is disposed along the third L-shaped steel 35 attached to the upper part of the car member 3 in the plurality of greening units 2 arranged side by side. Further, as shown in FIG. 1 (b), an opening is provided with a knife or the like at an oblique upper surface position in the bag body 41 of each vegetation sandbag bag 4, and a plant or the like planted with the plant P is planted from the opening. Thus, the green wall structure according to the present invention is completed.

  FIG. 7 shows another form of the greening unit. The greening unit 2A is substantially the same as the greening unit 2 shown in FIG. That is, an appropriate number of vegetation sandbags 4 are accommodated in the car member 3, and an appropriate number of first L-shaped steel 32 (not shown in FIG. 7) is attached to the lower end of the car member 3, and the upper end side. A third L-shaped steel 35 for supporting the irrigation pipe 5 and a fourth L-shaped steel 36 for fixing are attached to form a greening unit 2A. Since the greening unit 2A can be formed entirely by an assembling operation on the ground, the greening unit 2A can be easily assembled.

  When the greening unit 2A of this form is used, both the second L-shaped steel 12 and the fastening plate 13 are attached to the support columns 1 and 1 in advance. Then, the posture is such that the lower end of the greening unit 2A is placed on the second L-shaped steel 12, and then the posture in which the greening unit 2A is erected. Thereafter, the fourth L-shaped steel 36 and the fastening plate 13 are fixed with bolts and nuts, and the attachment of the greening unit 2A to the columns 1 and 1 is completed. In the greening unit 2A of this form, each accommodated vegetation sandbag 4 may remain substantially cylindrical. By pressing the greening unit 2A against the support columns 1 and 1 at the time of attachment, the end portion of each vegetation sandbag 4, that is, the portion in contact with the support column 1 can be naturally deformed to have the shape shown in FIG.

  FIG. 8 shows another example of the car member 3. The car member 3A is composed of a main body 3A1 shown in FIG. 9 and a lid member 3A2 shown in FIG. In any case, as in the case of the car member 3 described above, the metal wire 31 that has corrosion resistance or has been subjected to corrosion resistance treatment is knitted or welded at predetermined intervals in the vertical and horizontal directions. The main body 3A1 has a flat U-shape. As shown in the figure, an appropriate number of the first L-shaped steels 32 are attached to the lower end side, and the irrigation pipe 5 is supported on the upper end side. For this purpose, a third L-shaped steel 35 for fixing and a fourth L-shaped steel 36 for fixing are attached. The lid member 3A2 has a flat plate shape and is large enough to cover the open side of the main body 3A1.

  In order to make the greening unit 2B using the car member 3A, first, the main body 3A1 is placed on a flat surface or an inclined surface with the open side as the upper side. Next, an appropriate number of the above-mentioned vegetation sandbags 4 are accommodated therein, and then the lid member 3A2 is placed on the open side of the main body 3A1 and integrated by appropriate means. Thereby, a greening unit 2B as shown in FIG. The greening unit 2B is attached to the support columns 1 and 1 in the same manner as the greening unit 2A. Even in the greening unit 2B of this form, the accommodated vegetation sandbags 4 may remain substantially cylindrical. As in the case of the greening unit 2A, the end of each vegetation sandbag 4 is naturally deformed by pressing the greening unit 2B against the columns 1 and 1, and the shape shown in FIG. 4 can be obtained.

  As described above, in the greening wall structure A according to the present invention, only the surface that needs to be greened can be covered with an appropriate number of greening units 2, and each greening unit 2 is a greening plant only for its own area. Since it only needs to be greened with P, the area where greening is required can be greened in a short time. Moreover, by planting different greening types P in the individual greening units 2, it is possible to construct a greening wall structure with high design. In addition, when a specific planting unit 2 dies out or the like, only the planting unit 2 needs to be replaced, and the maintenance cost can be reduced.

  In the construction, it is only necessary to attach each of the greening units 2 using the upright columns 1 and 1, and the work is easy. Furthermore, each greening unit 2 is mounted between the columns 1 and 1 in a posture in which a part protrudes from the front surface of the columns 1 and 1, and the greening unit 2 is also installed in the space corresponding to the thickness of the columns 1 and 1. Since part of 2 enters, waste of space can be eliminated.

  Furthermore, the irrigation pipe 5 is arranged on the upper part of the car member 3 in each greening unit 2, and water can be reliably supplied to the vegetation sandbag 4 accommodated in each car member 3. Growth progresses smoothly.

  Further, in the illustrated example, the vegetation sandbag 4 is accommodated in the car member 3 in a state where the front surface of the support 1 can be covered, so that the standing support 1 grows from the vegetation sandbag 4 and further from there. Since it can cover with the greening plant P to be done, the greening wall structure which does not feel uncomfortable in design property is obtained.

  Moreover, the opening is provided in the diagonal upper surface of each accommodated vegetation sandbag bag 4, and a greening plant is planted there, and it can prevent that soil leaks from the opening carelessly. In particular, in the illustrated example, the vegetation sandbag 4 is housed in the car member 3 in a state where it cannot be freely moved due to deformation of the vegetation sandbag 4, and the cage due to the weight of the greening plant P planted in the vegetation sandbag 4 It is possible to reliably prevent the vegetation sandbag 4 from rotating downward in the member 3 and inadvertently leaking soil from the opening.

  Moreover, in the said greening wall structure, the bag body 41 which comprises the vegetation sandbag bag 4 is equipped with the function which suppresses that the root of the greening plant P expand | extends, and becomes independent for every vegetation sandbag bag 4. Thus, the greening plant P can be grown.

  Further, the greening wall structure A shown in the figure has a mode in which the greening unit 2 is attached only to one side of the column 1, but the greening unit 2 can be similarly attached to the opposite side of the column 1. By attaching the greening unit 2 to both sides of the support 1, a greener wall structure with higher design can be obtained.
