Description

  The present invention relates to a planting base and a greening device.

  Patent Literature 1 discloses a technology related to a wall surface greening device for greening the outer wall surface of a structure such as a building. In this prior art, a protection plate for protecting plants from wind and solar radiation is arranged outside the plants climbed on a wire or the like. This protective plate is formed of a perforated folded plate having a hole penetrating in the plate thickness direction and having a mountain-shaped portion bent into a mountain-shaped cross section.

JP 2013-153657 A

  However, the greening technique of Patent Document 1 has a structure in which a plant planted in a planter is climbed on a wire or the like. Therefore, when receiving wind pressure, the wires and the like may be deformed and the plant may fall down. For this reason, in the greening technology of this patent document 1, the wind pressure which hits a plant is suppressed with a protective plate. However, since the plant is seen through the protective plate in which the hole is formed, the plant cannot be fully appreciated. Therefore, there is a need for a plant base having high rigidity that can withstand wind pressure.

  Further, according to the tree planting technique of Patent Document 1, plants to be planted are limited to plants climbing by extending a stem portion with a low rigid wire or the like for a long time, mainly vines. For this reason, applicable plant species are restricted, and it is difficult to form wall greening with high design properties. Therefore, there is a need for a planting base having high rigidity with few restrictions on applicable plant species.

  The present invention has been made in view of the above circumstances, and has as its object to provide a planting base having high rigidity.

  The first aspect is a planting mat configured by stacking a plurality of planting sheets, and a pair of corrugated plates that hold the planting mat sandwiched from both sides so that the ridgeline directions of the wave peaks coincide with each other. And a storage part formed with the planting sheet drawn out from a hole formed in at least one of the corrugated plates, in which a plant is planted.

  In the first embodiment, a planting mat formed by stacking a plurality of planting sheets is integrated by sandwiching the planting mat from both sides with a pair of corrugated plates. Therefore, compared with the case where a plant is climbed on a wire, it becomes a planting base having higher rigidity.

  A second aspect is the planting base according to the first aspect, wherein the planting sheet is formed of a sheet-like porous body.

  In the second aspect, the planting sheet constituting the planting mat of the planting base is formed of a sheet-like porous body having both excellent water retention and drainage properties. Growth conditions such as air and air conditions can be suitably maintained.

  A third aspect is a planting base according to the first aspect or the second aspect, a supporting means for supporting the planting base such that a ridge line direction of a wave peak of a corrugated plate is in a horizontal direction or a vertical direction, and A watering device for watering from the upper end of the planting mat on the planting base.

  In the third aspect, water irrigated from the upper end of the planting mat on the planting base flows down in the planting mat by gravity. Therefore, the roots of the plants planted in the housing extend in the planting mat and absorb water.

  On the other hand, surplus water that is not required for plant growth is drained from the lower end of the planting mat. Further, the corrugated plate has a large heat radiation area to the air, and the convection transfer speed of heat to the air due to the generation of turbulence around the corrugated plate increases. Therefore, the temperature rise of the planting base can be suppressed. Therefore, in the planting mat, moisture conditions, air conditions, temperature conditions, and the like are suitably maintained for the growth of the planted plant.

  According to the present invention, a planting base having high rigidity can be provided.

Next, the operation and effect of the present embodiment will be described.

  The planting base 10 of the present embodiment is integrated with a planting mat 20 formed by stacking a plurality of (two in the present embodiment) planting sheets 22 sandwiched between a pair of corrugated plates 30 and 31 from both sides. The configuration is as follows. Therefore, compared with the case where the plant is climbed on the wire, the planting base 10 has higher rigidity. Therefore, bending of the planting base 10 due to wind pressure is suppressed.

  In addition, by improving the load bearing performance by increasing the rigidity of the planting base 10, the support member 110 that supports the planting base 10 can be simplified. This makes it possible to reduce the number of parts, reduce costs, improve workability, improve design, and the like.

  Further, by increasing the rigidity of the planting base 10, the ability of the planting base 10 to hold the plant 90 is improved. Therefore, the types of the plants 90 that can be planted on the planting base 10 increase.

  Further, the corrugated plate 30 constituting the outer surface of the planting base 10 has a large heat radiation area to the air, and the convection transfer speed of the heat to the air due to the generation of turbulence around the corrugated plates 30 and 31. Get higher. Therefore, temperature rise of the planting base 10 (particularly, the planting mat 20) is suppressed.

  Further, since the planting sheet 22 constituting the planting mat 20 is formed of a sheet-like porous body having both excellent water retention and drainage properties, the growth condition of the plant 90 is influenced by water conditions, air conditions, and the like. Can be suitably maintained.

  Further, the water irrigated from the upper end of the plant mat 20 of the plant base 10 flows down in the plant mat 20 by gravity. Therefore, the root 92 of the plant 90 placed on the planting mat 20 absorbs water. On the other hand, surplus water that is not required for growing the plant 90 is drained from the lower end of the planting mat 20.

  Therefore, in the planting mat 20, moisture conditions, air conditions, temperature conditions, and the like are suitably maintained for the growth of the planted plant 90.
