Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a greening panel for ground cover plants for growing plants on an artificial ground such as a rooftop of a building or a veranda, and particularly for growing ground cover plants.
[0002]
[Prior art]
  Conventionally, when a plant is cultivated on an artificial ground such as a rooftop of a building or a veranda, a waterproof layer and a root-preventing layer are applied, and then soil is placed thereon, and the plant is cultivated thereon.
[0003]
  However, in the above-mentioned conventional example where the soil is piled up, the load on the building is large, which affects the design of the building, and also requires extensive waterproofing work. In addition, there is a problem that the cost of the greening work on the artificial ground becomes high. Furthermore, in the case of an existing building, due to an increase in load due to soil accumulation, there was a case where the above greening work could not be applied.
[0004]
  In addition, since the load is large, not only the initial construction as described above is troublesome, but also transfer and expansion are troublesome work, and there is a problem that the transfer and expansion cannot be easily performed.
[0005]
  In addition, in the past, in order to grow roots and entangle the roots, soil is always necessary, and since the operator handles the soil, the work is difficult and the surroundings of the part where the work is performed are soiled, There was also a problem that the worker himself was dirty, and there was also a problem that the soil was washed away by rain or scattered by wind. Furthermore, since the soil could not be uniformly replenished with water, plant growth was uneven. In addition, in the case of thin soil, there are many plants that wither only with natural water. Therefore, management such as water replenishment is necessary, but conventionally watering by hand or using an automatic irrigator etc. However, watering by hand is troublesome and uniform and appropriate water supply is not possible. In the case of an automatic irrigator, construction and maintenance are cumbersome, equipment costs are high, running costs are high, and relocation There was a problem that it was difficult to respond easily to expansion and expansion.
[0006]
[Problems to be solved by the invention]
  The present invention has been made in view of the above points, is light and easy to handle, can be easily moved and expanded, and can easily replenish water to ground cover plants with a simple configuration. Good rooting function, excellent water retention function, easy to handle, can be securely connected between adjacent boxes, has a function to give fertilizer to plants, and can prevent plant scattering, It is an object of the present invention to provide a greening panel for a ground cover plant that can have an optimal amount of water depending on the type of plant and that can further increase the heat insulation with the building and reduce the heating and cooling costs of the building.

May be provided. The box 2 is made of a material that does not allow water to pass through.
[0021]
  The water permeable unit body 1 placed in the box 2 has water permeability made of a porous material, and as an example, a large number of continuous small gaps such as sponge, synthetic resin foam, porous rubber, etc. And having flexibility and being composed of a single material or a porous material and other composite materials. The synthetic resin foam used in this example is a synthetic resin foam having open cell flexibility.
[0022]
  Other examples include a porous material such as shirasu balloon or pearlite in which glassy volcanic ash is foamed, a large number of continuous small voids such as ceramic, pumice, and synthetic resin foam, and a box 2 described later. A single material having rigidity capable of connecting each other, or a porous material and other composite materials are used. The synthetic resin foam used in this example is an open-cell non-flexible one.
[0023]
  First, the water permeable unit body 1 is composed of a flexible porous material 3 having a large number of continuous small voids such as sponge, synthetic resin foam, and porous rubber and having flexibility.ExampleI will explain.This exampleIn FIG. 1, the water-permeable unit body 1 is formed in a substantially plate shape as shown in FIG. 1 by a flexible porous material 3 having a large number of continuous small voids and having flexibility.This exampleSince the water-permeable unit body 1 is composed of a flexible porous material 3 having a large number of continuous small voids and flexibility, the water-permeable unit body 1 is water collected in the box body 2 due to capillary action. , A water retention function by having a large number of continuous small gaps, and a rooting function by having a large number of continuous small gaps and having flexibility.
[0024]
  Therefore,When the water permeable unit body 1 is used, it has a water sucking function, a water retaining function, and a root tangling function, so that the water permeable unit body 1 is placed in the box 2 and the upper surface of the water permeable unit body 1 is used. The ground cover plant 15 such as turf or sedum can be directly placed and cultivated. That is, the roots of the ground cover plant 15 have a large number of continuous small gaps and can enter and grow into the flexible water permeable unit body 1 and can be easily entangled. Even if it grows thicker, the permeable unit body 1 is made of the flexible porous material 3 so that it can be easily accommodated by deformation around the inner small gap, which is sucked up by capillary action and has flexibility. The water retained in the small gaps in the water-permeable unit body 1 can be directly supplied to the roots of the plants in the water-permeable unit body 1 so that the plants can grow well.Therefore,Good plant growth can be achieved without providing a separate root entanglement layer, and the configuration can be simplified. Of course, depending on the type of plant,Permeability unit body 1It is also possible to separately provide a root entanglement layer made of a nonwoven fabric layer or the like. Also,As shown in FIG.A hole 8 for a root to enter the water-permeable unit body 1 may be formed.

It can be done. Also described belowExamplesThe hole 8 for the root to enter the water permeable unit body 1 may also be formed.
[0025]
  In addition, since the water-permeable unit body 1 made of the flexible porous material 3 is deformed when a large load is applied, the flexible porous material 3 is added to increase the load resistance and increase the rigidity of the water-permeable unit body 1 as a whole. And the rigid frame material 7 may be combined to improve load resistance. That is, as shown in FIG. 4, a rigid frame material 7 formed of a synthetic resin or metal is embedded in a flexible flexible porous material 3.In FIG.In the frame material 7, the cylinder body 7 b is integrally connected to each crossing portion of the lattice frame 7 a, and the root of the cylinder body 7 b enters in the state where the frame material 7 is embedded in the flexible porous material 3. Hole 8 is formed. By combining the flexible porous material 3 and the rigid framework material 7 in this way, the rigidity of the water permeable unit body 1 can be improved and the load resistance can be improved.
[0026]
  Next, based on FIG.Other examplesI will explain.FIG.The water-permeable unit body 1 is configured by filling the porous granular material 4 into a bag 5 having a large number of small holes 5a. Here, the porous particles 4 filled in the bag 5 may be any of the porous materials having water permeability described above (for example, porous materials such as shirasu balloon or pearlite obtained by foaming glassy volcanic ash, ceramics, etc. Pumice, sponge, synthetic resin foam, porous rubber, etc.) can be used, and the bag 5 is filled with a granular material of these porous materials.
[0027]
  This exampleSince the water-permeable unit body 1 is configured by filling the porous granular material 4 in the bag 5 having a large number of small holes 5a, the space between the large number of porous granular materials 4 in the water-permeable unit body 1 is A large number of continuous small gaps are formed, and the function of sucking up the water accumulated in the box 2 due to the capillary action of the small gaps and the porous granular body 4 itself, the large number of continuous small voids and the porous granular body 4 Since it has a water retention function and the porous granular bodies 4 are in a non-fixed relationship, the roots of the plants enter the small gaps between the porous granular bodies.Easy to growIt is easy to get entangled. Therefore,thisWhen the water permeable unit body 1 is used, it has a water sucking function, a water retaining function, and a root tangling function, so that the water permeable unit body 1 is placed in the box 2 and the upper surface of the water permeable unit body 1 is used. The ground cover plant 15 such as turf or sedum can be directly placed and cultivated. That is, the roots of the ground cover plant 15 enter the bag 5 through the small holes 5a of the bag 5 and grow into the small gaps between the large number of porous granular bodies 4 in the bag 5 so that they can be easily entangled. In addition, even if the roots of the plant grow and become thick, the porous granules 4 are in a non-fixed relationship, so that the roots of the plants enter the small gaps between the porous granules 4.Easy to growAs a result, the water that has been sucked up by capillary action and retained in the permeable unit body 1 can be directly supplied to the root of the plant in the permeable unit body 1 so that the plant can grow well. is there.Therefore,Good plant growth can be achieved without providing a separate root entanglement layer, the configuration can be simplified, and the porous granular material 4 is easy to handle because it is in a bag. Of course, depending on the type of plant,Permeability unit body 1It is also possible to separately provide a root entanglement layer made of a nonwoven fabric layer or the like.
