Description

  The present invention relates to a wall surface greening device for greening an outer wall surface of a structure such as a building.

2. Description of the Related Art Conventionally, wall surface greening is performed to cover an outer wall surface of a structure such as a building with a plant. And thereby, the cooling of a structure and the improvement of a landscape are aimed at.
Such wall greening methods can be divided into several types. For example, a type in which the main body part of a plant such as a leaf or stem is attached to the outer wall surface of the structure (for example, a panel type), or a type in which the main body part is entangled with a wire or net provided near the outer wall surface (for example, climbing) Type), or a type (for example, a hanging type) in which the main body portion is suspended from above such as a rooftop (Patent Document 1).

JP 2000-300079

  However, regardless of the type, the main part of the plant is directly exposed to the wind or exposed to strong sunlight in the West or summer. From the wind, the leaves and stems are shaken and rubbed and subjected to stress due to drying, and from solar radiation, the stress is caused by high temperature and drying, and if such stress is excessive, poor growth Cause.

  Here, as a measure for reducing the stress, it is conceivable to provide a protective member such as a protective plate or a protective net at an outer position on the side of the plant, and to allow the protective member to receive wind or solar radiation.

However, if a non-perforated plate without a through hole is used as the protective plate, the non-perforated plate completely obstructs the field of view, and no plants can be seen through the non-perforated plate. Then, the landscape improvement which is one of the purposes of wall greening cannot be achieved. Moreover, if the solar radiation is completely blocked, there is a risk of causing poor plant growth.
On the other hand, when a protective net is used, it is conceivable that the protective net is easily deformed and pressed against the plant by the wind pressure in a strong wind due to its flexibility, and as a result, it may not function effectively as a protective member.

  The present invention has been made in view of the conventional problems as described above, and its purpose is to increase the rigidity of the protective plate so that the wind pressure can be reliably received, and wind-induced stress that can act on the plant. While reducing the stress caused by solar radiation, the plant on the outer wall surface of the structure is maintained in a state where it can be seen from the outside of the structure, and the poor growth of the plant is avoided.

  FIG. 2 thru | or FIG. 4 is explanatory drawing of the wall surface greening apparatus 10 of this embodiment. FIG. 2 is a front view of the wall surface greening device 10 as seen from the outside on the side, and shows a part of the device 10 in an enlarged manner. Moreover, FIG. 3A is a front view which further expands and shows the same wall surface greening apparatus 10, and FIG. 3B is BB sectional drawing in FIG. 3A. Moreover, FIG. 4 is the perspective view which looked at the wall surface greening apparatus 10 from the outer side, and shows a part of the apparatus 10 in an enlarged manner. In addition, in FIG. 2, FIG. 3A and FIG. 4, the plant 20 used for wall surface greening is not illustrated.

  As shown in FIGS. 3A and 3B, the wall surface greening device 10 includes a plant 20 that is provided facing the outer wall surface 1 </ b> W of the building 1 and greens the wall surface 1 </ b> W, and an outward position lateral to the plant 20. Are disposed opposite to the plant 20 and protect the plant 20 from wind and solar radiation.

  As shown in FIG. 3B, the plant 20 is provided in the vicinity of the outer wall surface 1 </ b> W using a known method for wall greening. In this example, a climbing method using vines is used. That is, the planter 21 for planting is arranged near the lowermost part of the greening target portion A10 on the outer wall surface 1W, and a plurality of climbing wires 22, 22, ... (or nets) extending in the vertical direction are arranged in the wall width direction. Are intermittently arranged, and climbing the vine plant 20 on these wires 22, 22, etc., the leaves and stems of the vine plant 20 cover the greening target portion A 10 of the outer wall surface 1 W, thereby realizing wall greening. ing. In addition, as a specific example of the vine plant 20, hedera, giant persimmon, and the like are listed, and the planting base 20 b of the vine plant 20 is accommodated in the planter 21. In addition, when the greening target part A10 includes the first floor above the ground, the planter 21 is placed on the ground GND or the foundation B, for example, while the greening target part A10 does not include the first floor above the ground, and the second floor or more above the ground. When it includes three or more floors, the planter 21 is placed on a floor member (not shown) such as a grating provided near the lowermost part of the greening target portion A10. Moreover, in the example of FIG. 3B, the space | interval D20 is provided between the vine plant 20 and the outer wall surface 1W, However, This space | interval D20 does not need, ie, makes the vine plant 20 contact | abut to the outer wall surface 1W. Also good. Other wall greening methods (for example, the “droop method” and “panel method”) will be described later.

  On the other hand, the protection plates 30, 30... Are arranged at an outer position than the plant 20, that is, at a position farther from the outer wall surface 1W than the plant 20 with respect to the side in order to protect the plant 20 from wind and solar radiation as described above. Has been. In other words, the protection plates 30, 30... Are arranged with one side (back side) facing the outer wall surface 1W with a distance D30 on the side of the outer wall surface 1W, and the outer wall surface 1W and the protection plate 30. , 30... And according to this arrangement, before the plant 20 is subjected to wind and solar radiation, the protection plates 30, 30... Receive these winds and solar radiation, and the weakened wind and solar radiation hit the plant 20. The stress caused by wind and solar radiation is effectively reduced.

  In this example, the protection plates 30, 30... Have a plurality of substantially rectangular shapes in plan view having a plate length direction (longitudinal direction), a plate width direction (width direction), and a plate thickness direction (thickness direction). It has perforated plates 32, 32. As shown in FIGS. 3A and 2, each of the perforated folded plates 32 has a plate length direction in the horizontal direction (wall width direction of the outer wall surface 1W) and a plate width direction in the vertical direction (of the outer wall surface 1W). It is arranged in a line in the vertical direction while facing the wall height direction. Thereby, the folded plate 32 is arranged in a state in which the other (front side) plate surface of the perforated folded plate 32 faces outward. Then, a group of the plurality of perforated folded plates 32, 32... Arranged in the vertical direction is defined as one unit U32, and a plurality of such units U32 are arranged along the wall width direction of the outer wall surface 1W. .. Are provided so as to cover the greening target portion A10 of the outer wall surface 1W from the side. Incidentally, the units U32, U32... Are also schematically shown by two-dot chain lines in FIG.

  As shown in the perspective view of FIG. 4, each perforated folded plate 32 is supported by an appropriate support member 40. As the support member 40, for example, stay members 42, 42... Projecting laterally from the outer wall surface 1 W of the building 1, and columnar members 44, 44. And a configuration having The stay members 42, 42... And the columnar members 44, 44... Are provided intermittently side by side in the wall width direction, and each of the stay members 42, 42. The perforated folded plates 32, 32,... Are supported by the columnar member 44 by spanning the perforated plates 32, 32 in the horizontal direction and fixing them with bolts or the like.

  As shown by its name, the perforated folded plate 32 shown in FIG. 4 has a plurality of holes 32h, 32h... Penetrating in the thickness direction, and a mountain-shaped portion 32m bent into a mountain-shaped cross section. doing. The bending to the cross-sectional mountain shape is performed by bending along folding lines L32, L32... Set on the plate 32. And these fold lines L32, L32... Are along the plate length direction, whereby the cross-sectional shape when the perforated folded plate 32 is cut in a cross section parallel to the plate width direction is formed into a cross-sectional mountain shape. Yes. In addition, by having the said mountain-shaped part 32m, the cross-sectional secondary moment of the perforated folded plate 32 has improved significantly, and this is the bending for opposing the wind pressure which acts from the normal direction of a plate surface. The rigidity is increased. Therefore, the perforated folded plate 32 can receive the wind firmly without substantially deforming.

  In this example, each perforated folded plate 32 has only one mountain-shaped portion 32m, and the perforated folded plate 32 has an outer dimension of all perforated folded plates based on standard dimensions. Although the same size is provided over 32, 32..., It is not limited to this. For example, a plurality of mountain-shaped portions 32m, 32m, ... may be formed in the plate width direction with respect to one perforated folded plate 32, or two perforated folded plates 32 may be formed in the plate width direction. A single perforated folded plate having an outer dimension of a plurality of sheets such as three may be used. That is, as a matter of extreme discussion, the plurality of perforated folded plates 32, 32... Are not used as the protection plate 30 as described above, but a size corresponding to the planar size of the greening target portion A10 on the outer wall surface 1W of the building 1. A single perforated folded plate may be used as the protective plate 30.

  Incidentally, as described above, each perforated folded plate 32 has a plurality of holes 32h, 32h... Penetrating in the thickness direction. And wind and sunlight hit the plant 20 through these holes 32h, 32h. Therefore, most of the wind and solar radiation are received by the perforated folded plate 32, and a small amount of wind and solar radiation reduced through the holes 32h, 32h, etc. hits the plant 20, and as a result, the wind toward the plant 20 The amount of solar radiation necessary for the growth of the plant 20 is secured while reducing the stress caused by the solar radiation and the stress caused by the solar radiation. Moreover, since the plant 20 can be seen through the perforated folded plate 32 through each hole 32h, the plant 20 can be maintained in an appreciable state from the outside of the building 1, and as a result, the building which is the main purpose of wall greening 1 landscape improvement.

  Here, as shown in the schematic cross-sectional views of FIGS. 4 and 5, the holes 32h are respectively formed on the slope portions 32mk and 32mk located on both sides of the top portion 32mp of the mountain-shaped portion 32m of the perforated folded plate 32, respectively. Is formed. That is, a plurality of holes 32h, 32h,... Are formed through both the upper slope portion 32mk located above the top portion 32mp and the lower slope portion 32mk located below the top portion 32mp. Thereby, as shown in FIG. 5, sunlight can be mainly taken from the holes 32h, 32h ... in the upper slope part 32mk and applied to the plant 20, and the holes 32h, 32h ... mainly in the lower slope part 32mk. Through this, a person can see the plant 20 from the outside. Therefore, even if the protection plates 30, 30... Are arranged at a height higher than the height of the person, the landscape can be improved reliably while ensuring appropriate solar radiation to the plant 20. The wall surface greening device 10 is more flexible in the installation position.

  In the example of FIGS. 4 and 5, holes 32h, 32h,... Are formed not only in the slope portions 32mk and 32mk but also in the top portion 32mp, and further extend in a vertical direction from the slope portions 32mk and 32mk. Holes 32h, 32h... Are also formed in the bottom surface portions 32b, 32b, thereby making it easier to view the plant 20 through the perforated folded plate 32.

  As an example of the shape of the hole 32h, here, a round shape such as the top 32mp and the hole 32h of the slope portion 32mk shown in FIGS. 3A and 4 and an oval shape such as the hole 32h of the bottom surface 32b are illustrated. However, it is not limited to this. That is, it may be a circular shape other than a circular shape or an elliptical shape (for example, a shape in which a plurality of arcs having different curvatures are combined), a polygon such as a triangle or a quadrangle, and the circular shape and the polygonal shape may be partially A composite shape formed by combining them with each other or a shape based on an appropriate design such as a star shape may be used.

  Further, the arrangement pattern of the holes 32h is also aligned in a line at a predetermined pitch in the plate length direction such as the staggered pattern such as the holes 32h of the sloped part 32mk shown in FIGS. 3A and 4 and the holes 32h of the top part 32mp and the bottom part 32b. The pattern is not limited to a single line pattern, and may be a lattice pattern or a pattern based on an appropriate design. Further, the holes 32h may be arranged in a staggered pattern or a lattice pattern instead of the one-line pattern of the top part 32mp and the bottom part 32b, and conversely, the holes 32h may be arranged in a one-line pattern on the inclined surface part 32mk. Furthermore, the holes 32h may be randomly arranged regardless of the arrangement pattern as described above.

  The opening area of each hole 32h may be set to an appropriate size in consideration of ornamental properties and the like. Moreover, the hole area ratio of each perforated folded plate 32 (that is, the ratio of the total perforated area in the plate surface of the perforated folded plate 32 including the hole 32h) is desirably 10 to 50. % Should be selected. If selected from such a range, while ensuring the strength of the perforated folded plate 32, it effectively reduces the stress caused by wind and solar radiation on the plant 20, and allows the plant 20 to pass through the perforated folded plate 32. You will be able to see for sure. In addition, for each perforated folded plate 32, the opening area or the opening rate of each hole 32h may be varied. In the example of FIG. 6, the perforated folded plates 32, 32,... Having a hole area ratio of 50%, 30%, and 10% are sequentially arranged in this order in the vertical direction. If the arrangement order of the perforated plates 32, 32... Is changed in the vertical direction, or the aperture ratio of each perforated folded plate 32 is changed from the above numerical value, the perforated folded plates 32, 32. The overall impression changes. Therefore, various designs can be expressed on the wall surface greening device 10 by appropriately changing the aperture ratio and the aperture area of each hole 32 h for each perforated folded plate 32.

  2 to 4, the perforated folded plates 32, 32... Are arranged so that a gap G is formed between the perforated folded plates 32, 32 adjacent in the vertical direction. That is, as shown in FIG. 4, the gap G is provided between the lower end edge 32ed of the perforated folded plate 32 and the upper end edge 32eu of the perforated folded plate 32 adjacent to the lower side thereof. And if it arrange | positions in this way, sunlight can be applied to the plant 20 also from the said gap | interval G, and it becomes possible to avoid the growth defect resulting from lack of solar radiation effectively. Moreover, since the plant 20 can be seen not only through the hole 32h but also through the gap G, the plant 20 can be more easily viewed from the outside of the building 1. The size DG in the vertical direction of the gap G is selected from a range of, for example, about 30 mm to the width of the perforated folded plate 32 (dimension in the plate width direction). However, the gap G is not an essential configuration. That is, as shown in the perspective view of FIG. 7, the lower end edge 32 ed of the perforated folded plate 32 and the upper end edge 32 eu of the perforated folded plate 32 adjacent to the lower side thereof are arranged to face each other to eliminate the gap G. Also good. Alternatively, the gap G is provided for all the perforated folded plates 32, 32 as shown in FIG. 4, or the gap G is not provided for all the perforated folded plates 32, 32, as shown in FIG. Instead of doing so, the presence or absence of the gap G may be combined. That is, the gap G may be provided for some of the perforated folded plates 32, 32, and the gap G may not be provided for the other some perforated folded plates 32, 32,.

  In addition, although the amount of sunlight required for the plant 20 changes with plant species, from the viewpoint of ensuring the amount of sunlight, in the case of having the gap G, the perforated folded plate 32 is used as the hole area ratio of the wall surface greening device 10. What is necessary is just to adjust the whole opening rate including both the hole 32h and the clearance gap G. In the case of hedera that can grow even under low illuminance conditions, it is desirable that a hole area ratio of approximately 20% or more is secured as the hole area ratio of the wall surface greening device 10 in consideration of airflow inhibition and the like.

  Examples of the material of the perforated folded plate 32 include metals such as steel and aluminum, wood, resin, and the like. In this example, a hot dip galvanized steel plate is used to improve weather resistance. However, the material is not limited to the above, that is, any material other than those described above may be used as long as the protective plate 30 has rigidity and chemical stability that does not deform even when directly subjected to wind and solar radiation. .

  By the way, as in the example of FIG. 3B, the top 32mp of the mountain-shaped portion 32m of each perforated folded plate 32 is arranged outward to the side, that is, facing away from the outer wall surface 1W of the building 1. In this case, the concave space SP32m formed on the side opposite to the top 32mp along with the cross-sectional mountain shape of the mountain-shaped portion 32m is opposed to the plant 20 and the outer wall surface 1W of the building 1. In this case, various functional members may be accommodated in the concave space SP32m.

  Examples of the functional member include a water retaining material 52, a mist nozzle 55, and an illumination 57. And you may accommodate in said concave space SP32m combining one type or multiple types of these.

  The water retention material 52 shown in FIG. 8A is a member having water retention, and specific examples include fibrous members such as nonwoven fabric and woven fabric, sponge members, water retention stone materials, water retention ceramic members, and the like. The water retaining material 52 retains moisture almost constantly by the water supply from the water supply pipe 53 accommodated in the concave space SP32m together with the water retaining material 52, and cools the perforated folded plate 32 by the heat of vaporization during the evaporation. Thus, the high temperature due to the solar radiation absorption of the folded plate 32 is prevented. This prevents the perforated folded plate 32 from becoming a radiant heat source, and as a result, it is possible to effectively avoid the surrounding space of the plant 20 from becoming a hot environment. For example, the water supply pipe 53 is arranged with its pipe axis direction along the plate length direction of the perforated folded plate 32, and a plurality of water supply ports (not shown) are intermittently provided in the water supply pipe 53 in the pipe axis direction. Is provided. The water supply port is, for example, a nozzle or a drip device (or dripper). And the cooling water sent to the water supply pipe 53 by a suitable water supply pump (not shown) etc. is supplied to the water holding material 52 from each water supply port part. The water supply pipe 53 is not an essential configuration. That is, the water supply to the water retaining material 52 may be covered by rainwater. However, it is preferable to provide the water supply pipe 53 because the water retaining material 52 can be maintained in the water retaining state without being influenced by the weather. In the example of FIG. 8A, the water retaining material 52 is provided for every other perforated folded plate 32, 32... Arranged in the vertical direction, but the present invention is not limited to this. , May be provided for all the perforated folded plates 32, 32.

  As shown in FIG. 8B, the mist nozzle 55 supplies the mist to the plant 20 to prevent the plant 20 from being heated and dried, and the mist nozzle 55 is arranged with the spray port of the mist directed toward the plant 20. The mist nozzles 55 are disposed intermittently in the plate length direction of the perforated folded plate 32, and the water supply to the mist nozzle 55 is, for example, the concave space SP32m together with the mist nozzle 55. It is carried out by a water supply pipe (not shown) accommodated in In the example of FIG. 8B, the mist nozzles 55 are provided every other perforated folded plates 32, 32... Arranged in the vertical direction, but the present invention is not limited to this. , May be provided for all the perforated folded plates 32, 32.
