Description

[Technical Field]

[0001] The present invention relates to a greening structure and a greening method using the greening structure. [Background technology]

[0002] When greening the interiors of offices, commercial facilities, etc., there are two methods: forming a planting strip integral with the building structure, or installing planters on the floor. The method of forming a planting strip integral with the building is generally used when constructing a new building, and adopting it in an existing building requires large-scale renovation work. Therefore, when greening the interiors of existing buildings, it is common to install planters on the existing floor.

[0003] A planter is a container with a base and raised portions that can hold soil, plants, etc. In recent years, planters have been provided that are designed to ensure the appearance and shape appropriate to the installation location. For example, Patent Document 1 discloses a planter that allows the capacity and function to be changed while maintaining a unified appearance by selectively combining frame materials, decorative frame materials, lid materials, and partition materials.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-219454 Summary of the Invention [Problem to be solved by the invention]

[0005] In biophilic design, which aims to create a sense of nature, it is desirable for artificial elements to be visible as natural objects without being exposed.However, conventional planters that are installed on the floor expose artificial elements such as raised parts. To make planters look natural, there are techniques for printing natural objects on the planter or attaching natural stones to the sides. The planter in Patent Document 1 is made of wood. Even with these measures, the linear rise of the planter remains, and a natural design cannot be achieved.

[0006] An object of the present invention is to propose a greening structure and a greening method that can realize a natural design using soil and plants when greening indoors, etc. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a greening structure comprising a planter body having a base plate and walls capable of containing planting soil, and a soil hardening body covering the outer periphery of the walls. The edges of the base plate protrude outward from the walls. The soil hardening body is a hardened mixture of soil and a solidifying agent that is piled up and adhered to the outer surfaces of the walls and the upper surfaces of the edges.

[0008] The greening method of the present invention includes a planter installation step of installing a planter body formed of a base slab and a wall erected on the top surface of the base slab, a decorative body formation step of covering the outer surface of the wall with a mixture of a solidifying agent and soil, and a planting step of planting plants in the space enclosed by the wall. The edges of the base slab protrude outward from the wall, and in the decorative body formation step, the mixture is piled up to cover the upper surface of the edges. In the planting step, it is desirable to perform the steps of forming a drainage layer at the bottom of the space enclosed by the base slab and the wall, covering the upper surface of the drainage layer with a permeable sheet, and pouring soil on top of the permeable sheet.

[0009] According to this greening structure and greening method, the hardened soil body is raised around the outer periphery of the planter body, so that the linear walls (rising portions) are not exposed, realizing a natural design. Because the hardened soil body is mainly made of soil, it can be ensured to blend in with the planted area.

[0010] The solidifying agent may be, for example, an ethylene-vinyl acetate, cellulose-based or acrylic-based solidifying agent, and more preferably, an acrylic-based solidifying agent. Furthermore, by planting plants in the hardened soil, the amount of exposed soil can be reduced, and the amount of greenery per area can be increased. [Effects of the Invention]

[0011] According to the greening structure and greening method of the present invention, it is possible to realize a natural design using soil and plants when greening indoors, etc. [Brief explanation of the drawings]

[0013] In this embodiment, a greening structure to be installed indoors will be described. Figures 1 and 2 show a greening structure 1. As shown in Figure 2, the greening structure 1 of this embodiment includes a planter body 2, a hardened soil body 3, and a drainage layer 4. The planter body 2 is a container capable of containing planting soil (planting soil 6), and as shown in Figure 2, has a bottom plate 21 and walls 22. An edge 23 of the bottom plate 21 protrudes outward beyond the walls 22. The planter body 2 of this embodiment is made of stainless steel.

[0014] The soil hardening body 3 covers the outer periphery of the wall 22 of the planter body 2. The soil hardening body 3 is a hardened mixture of soil and a hardening agent. The soil hardening body 3 is piled up while adhering to the outer surface of the wall 22 and the upper surface of the edge 23 of the base slab 21. In this embodiment, an acrylic hardening agent is used as the hardening agent. Plants are also planted in the soil hardening body 3.

[0015] The drainage layer 4 is formed at the bottom of the space surrounded by the walls 22 of the planter body 2. The drainage layer 4 is formed by laying a resin drainage plate 41 on the base slab 21. The drainage plate 41 is a plate material with a plurality of holes 42 passing through it, and a plurality of posts 43 are formed on the underside. The drainage plate 41 of this embodiment has a plurality of holes 42 formed in a staggered pattern, and the posts 43 are formed between the holes 42. The posts 43 form gaps between the drainage plate 41 and the base slab 21 that allow water to pass through. A permeable sheet 5 is laid on the upper surface of the drainage layer 4 to prevent the planting soil 6 from falling downward through the holes 42.

[0016] Next, a greening method using the presently preferred embodiment of the greening structure 1 will be described. The steps of the greening method are shown in Figure 3. As shown in Figure 3, the greening method includes a planter installation step S1, a drainage layer formation step S2, a decorative body formation step S3, and a planting step S4. The planter setting step S1 is shown in Figure 4. In the planter setting step S1, the planter body 2 is set in a predetermined position as shown in Figure 4. The planter body 2 is formed in advance into a predetermined shape.

[0017] Figures 5 and 6 show the drainage layer forming step S2. In the drainage layer forming step S2, a drainage layer 4 is formed inside the planter body 2. In the drainage layer forming step S2, first, as shown in Figure 5, the drainage layer 4 is formed at the bottom of the space surrounded by the base slab 21 and the wall 22. The drainage layer 4 is formed by placing a drainage plate 41 on the base slab 21. After the drainage plate 41 is installed, the top surface of the drainage layer 4 is covered with a permeable sheet 5, as shown in Figure 6.

[0018] In the decorative body forming step S3, the outer surface of the wall 22 is covered with a mixture 31 of a solidifying agent and soil. In the decorative body forming step S3, first, the solidifying agent and soil are mixed to produce the mixture 31. The soil used is the same type as the soil used for the planting soil 6. Next, as shown in FIG. 6, the mixture 31 is piled up around the wall 22. The mixture 31 is piled up so as to cover the upper surface of the edge 23 and is in close contact with the wall 22 and the edge 23.

[0019] Fig. 7 shows the planting step S4. In the planting step S4, as shown in Fig. 7, plants are planted in the space surrounded by the wall 22 (inside the planter body 2). In the planting step S4, first, planting soil 6 is poured onto the water-permeable sheet 5. Next, predetermined plants are planted in the planting soil 6. In this embodiment, seeds are sown in the hardened soil body 3 in the planting step S4, and plants are also planted in the hardened soil body 3.

[0020] According to the greening structure 1 and greening method of this embodiment, the soil hardening body 3 is piled up around the outer periphery of the planter body 2, so that the straight walls 22 (rising portions) are not exposed, and a natural design is achieved.

[0021] The hardened soil body 3 is primarily made of the same type of soil as the planting soil 6, and because it is planted in place, it harmonizes with the planted areas inside the planter body 2. The hardened soil body 3 contains a hardening agent, making it robust and adhesive enough to withstand being trampled on by maintenance workers, gallery galleries, and the like, and is therefore resistant to crumbling. Furthermore, because it hardens while adhering closely to the wall 22 and the edge 23 of the base slab 21, it is difficult to peel off from the planter body 2. Furthermore, the hardened soil body 3 has gaps through which plant roots can penetrate and take root, so the soil is covered by the grown plants, reducing exposed soil and creating a more natural landscape.

[0022] The planter body 2 is easy to install because it can be installed by simply placing a planter body formed in a predetermined shape. Furthermore, since the planter body 2 is made of stainless steel, it can be easily formed into a desired shape and is also highly durable.

[0023] The drainage layer 4 is easy to install because it is formed by placing the drainage plate 41 on the base slab 21. In addition, the upper surface of the drainage layer 4 is covered with the permeable sheet 5, which prevents the planting soil 6 from falling off the drainage plate 41 while allowing excess water in the planting soil 6 to drain into the drainage layer 4.

[0024] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and each of the above-described components can be appropriately modified within the scope of the present invention. For example, in the above embodiment, the planter body 2 is described as being made of stainless steel, but the material of the planter body 2 is not limited and may be, for example, resin, ceramic, wood, etc.

[0025] In the above embodiment, the case where the drainage layer 4 is formed has been described, but the drainage layer may be formed as needed. Furthermore, drainage holes leading to the drainage layer 4 may be formed in the base slab 21 or the wall 22 as required. The drainage layer 4 is not limited to being formed by placing the drainage plate 41, but may be formed by laying granular material, for example. The water-permeable sheet 5 may be installed as needed.

[0026] Planting in the hardened soil body 3 may be carried out as needed. The soil used for the hardened soil body 3 is preferably similar in color to the planting soil 6 and has a similar particle size, but does not necessarily have to be the same. The solidifying agent used in the mixture 31 is not limited to an acrylic solidifying agent, but may be, for example, an ethylene-vinyl acetate, cellulose-based, or other agent that functions as a binder.

[0027] The order of the drainage layer forming step S2 and the cosmetic body forming step S3 is not limited, and for example, the drainage layer forming step S2 and the cosmetic body forming step S3 may be performed in parallel, or the cosmetic body forming step S3 may be performed before the drainage layer forming step S2. Furthermore, the order of the decorative body forming step S3 and the planting step S4 is not limited, and the soil hardening body 3 may be formed after the plants are planted in the planter body 2, or may be performed in parallel with the planting step S4.

[0028] The following shows the results of a plant germination and establishment test conducted on the solidifying agents used to produce the mixture 31 of the hardened soil 3. In this test, three types of solidifying agents were used: ethylene-vinyl acetate (Example 1), a cellulose-based solidifying agent (Example 2), and an acrylic-based solidifying agent (Example 3, acrylic acid ester copolymer). As a comparative example, a germination and establishment test was also conducted on soil that had not been mixed with a solidifying agent.

[0029] The solidification agent was 10.0 kg / m3 for the soil (perlite:bark compost = 7:3). 3 In Example 3, the acrylic solidifying agent was a liquid, so the amount added was 10.0 kg / m 3 Converting from the concentration, it becomes 28.6L / m 3 It was to be mixed. For the germination test, three test specimens were created by scattering 100 komatsuna seeds in each specimen, and the germination and establishment rates of the komatsuna were confirmed. Table 1 shows the test results.

[0030] [Table 1]

[0031] As shown in Table 1, all of the solidification agents had equivalent germination and establishment rates compared to Comparative Example 1, confirming that plant roots were able to penetrate and establish in the hardened soil body 3.

[0032] Next, the results of an experiment conducted to confirm the soil hardness of the hardened soil bodies 3 are shown. Similar to the germination and establishment test, this experiment was conducted using three types of solidifying agents: ethylene-vinyl acetate (Example 1), a cellulose-based solidifying agent (Example 2), and an acrylic-based solidifying agent (Example 3). For the test, an appropriate amount of water was added to a mixture of soil and solidifying agent, and the mixture was applied to a stainless steel planter to form two test specimens for each example. After 20 days, the hardened soil bodies 3 were confirmed to be dry, and then the soil hardness was measured at three locations for each test specimen using a Yamanaka soil altimeter. Additionally, each test specimen was trampled to confirm its shape and adhesiveness (treading resistance). Table 2 shows the test results.

[0033] [Table 2]

[0034] As shown in Table 1, it was confirmed that all of the solidifying agents exhibited a hardness of 15 mm or more and maintained their shape. Therefore, it was confirmed that the greening structure 1 of this embodiment can maintain the desired landscape after installation without the hardened soil body 3 collapsing. In terms of resistance to trampling, acrylic solidifiers showed the most desirable results in terms of shape retention and adhesiveness.

[0035] From the above results, it was confirmed that plants can be expected to germinate and the shape can be maintained regardless of which hardening agent is used for the soil hardened body 3. It was also confirmed that acrylic hardening agents are most desirable when it is expected that the soil will be stepped on during maintenance, etc. [Explanation of symbols]
