Description

[Technical Field]

[0001] The present invention relates to a panel on which plants are planted, and in particular to a wall greening panel that is attached directly to the wall surface of a building to green the wall surface. [Background technology]

[0002] Wall greening, in which plants are grown on the walls of buildings such as buildings and residences, has traditionally been practiced. Wall greening uses a sheet-like or panel-like planting base on which plants are planted. For example, a greening surface-forming member has been proposed that includes a support, a water-permeable support layer fixed to the surface of the support, a water-retaining layer that receives and retains water from the support layer, a water-conducting layer that receives water from the water-retaining layer from the back side and directs it to a root-spreading area on the front side, and a surface layer that covers the front side of the water-conducting layer and has a partitioned area created by stitching, and that includes a slit formed in the surface layer that leads to the root-spreading area (see, for example, Patent Document 1). The greening surface-forming member of Patent Document 1 can be attached directly to a wall surface for greening. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-99298 Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, in recent years, temperatures have risen significantly, especially in the summer, and the temperature of the exterior walls of buildings often rises due to exposure to direct sunlight. In this situation, when greening is directly applied to a wall surface using the greening surface forming member of Patent Document 1, the greening surface forming member is heated by the heat stored in the wall surface, which may inhibit the growth of planted plants and even cause them to wither and die.

[0005] Therefore, the present invention aims to provide a wall greening panel and wall greening structure that allows plants to grow healthily without being affected by heat emitted from the wall surface and that can green a wide area of ​​the wall surface with simple construction. [Means for solving the problem]

[0006] The first means adopted by the present invention to solve the above problems is a support plate, a planting base provided on the surface of the support plate, and a fixing means for fixing the wall surface to the green wall panel, The planting base includes a heat insulating layer in contact with the surface of the support plate, a water retention layer that retains moisture supplied from the outside and allows plants to take root, a root-resistant layer that is disposed between the heat insulating layer and the water retention layer and prevents plant roots from penetrating the heat insulating layer, and a surface layer that is disposed on the surface of the water retention layer and forms a planting pocket between the heat retaining layer and the water retention layer. the fixing means comprises a wall fixing portion attached to the wall surface and a panel fixing portion attached to the back surface of the support plate, and through holes are drilled near the four corners of the support plate and the planting base, and the panel fixing portion has two hole portions drilled at a predetermined interval along at least one of the vertical and horizontal directions, and is attached to the back surface of the support plate by inserting a bolt into one of the hole portions and one of the through holes and tightening it with a nut, and is also attached to the back surface of the support plate of another wall greening panel adjacent to the wall greening panel in question by inserting a bolt into the other hole portion and one of the through holes of the other wall greening panel adjacent to the wall greening panel in question and tightening it with a nut; It is a wall greening panel.

[0007] In the wall greening panel of the present invention, an insulating layer is placed on the side of the planting base that comes into contact with the support plate. This creates an insulating layer between the wall and the panel when it is attached to a building wall, reducing the internal temperature of the planting base from heat emitted from the wall. Furthermore, the planting pockets where plants are planted are formed from gaps between the water-retaining layer and the surface layer, eliminating the need for separate planting components, allowing the wall greening panel to be lightweight and enabling planted plants to take root directly in the water-retaining layer and absorb water.

[0008] In this specification and claims, the term "building" refers not only to buildings such as buildings, houses, and stores where people come and go, but also to fences and slopes, and the term "wall" refers to the walls that make up the interior and exterior surfaces of the above-mentioned buildings, as well as flat surfaces such as the roof of a building.

[0009] The planting pocket may be a gap formed between the surface layer and the water retaining layer when a lower portion of a horizontally elongated slit provided in the surface layer is pulled out.

[0010] This allows the formation of a planting pocket having a volume sufficient for planting a plant.

[0011] The second means adopted by the present invention is: A plurality of wall greening panels are fixed to the wall surface by the fixing means. , a wall greening structure.

[0012] The wall greening structure of the present invention is constructed by combining a plurality of wall greening panels fixed to a wall surface via fixing means, thereby enabling direct greening over any desired area of ​​the wall surface of a building or the like.

[0013] The wall greening structure may be provided with irrigation means for irrigating each of the plurality of wall greening panels, and may be provided with drainage means for receiving excess water leaking from the water retaining layer and discharging it to the outside.

[0014] The irrigation means irrigates the entire wall greening structure, ensuring a stable supply of water to each wall greening panel. The drainage means collects water that overflows from the wall greening panels when there is excessive irrigation, preventing it from dripping around the wall greening structure and directing it to a designated location such as a drainage ditch. [Effects of the Invention]

[0015] The wall greening panel and wall greening structure of the present invention include an insulating layer on the side of the planting base that contacts the support, reducing the transfer of heat generated by the wall to the planting base. This prevents the temperature inside the planting base from rising, preventing temperature changes from hindering the growth of plants planted in the planting pockets. Furthermore, the planting pockets are formed from the gaps between the water-retaining layer and the surface layer without using any additional components, making them lightweight. This reduces the weight load on the wall, allowing them to be installed safely on high-altitude walls and reducing the cost and effort required for construction. [Brief explanation of the drawings]

[0017] The present invention relates to a wall greening panel and wall greening structure for greening a wall surface.

[0018] The system comprises a wall greening panel, a support plate, and a planting base. The support plate is a plate-like member that forms the framework of the wall greening panel and can be made from a lightweight plate material that is rigid and does not easily bend, such as metal, resin, plaster, wood, or a composite of these. The thickness of the support plate is not particularly limited and can be set appropriately depending on the properties of the material, but it is preferable to make it thick enough to maintain rigidity without making it excessively thick.

[0019] The back surface of the support plate may be provided with a fixing means for fixing the wall greening panel to the wall surface. The fixing means is not particularly limited as long as it can fix the back surface of the support plate to the wall surface, and for example, a bracket may be used that is interposed between the support plate and the wall surface, with one end fixed to the back surface of the support plate and the other end fixed to the wall surface.

[0020] The planting base is a component of the wall greening panel in which plants are planted and grown. The planting base is placed on the surface of the support plate and is composed of an insulating layer, a root-resistant layer, a water-retaining layer, and a surface layer. The insulating layer is a layer of the planting base that forms the surface that comes into contact with the surface of the support plate, and is a sheet-like or plate-like component. This blocks heat transmitted from the wall surface through the support plate from being transmitted to the interior. Known insulating materials such as fiber-based and foamed plastic-based materials can be used for the insulating layer, but the use of nonwoven fabric insulating material is particularly preferable because it adds cushioning and water-retaining properties to the insulating effect, improving functionality.

[0021] The water-retaining layer is a sheet- or plate-like member that is placed between the heat-insulating layer and the water-retaining layer and that retains the moisture absorbed by plants planted in the planting pockets described in detail below, allowing the plants to take root. The water-retaining layer can be made of a material with excellent water absorption and water-retaining properties, such as a sheet of porous material such as nonwoven fabric, felt, urethane, or sponge. The thickness of the water-retaining layer is not particularly limited and can be set appropriately depending on the water-retaining properties of the constituent materials and the water-absorbing capacity of the plants to be planted.

[0022] The root-resistant layer is a layer that controls the rhizome area so that plant roots that have grown in the water-retaining layer do not penetrate the insulating layer. The root-resistant layer can be made of resin fibers such as polyester or polypropylene woven or molded into a sheet at high density. The thickness of the root-resistant layer is not particularly limited as long as it can ensure root resistance to the extent that plant roots do not penetrate the insulating layer. Furthermore, if the constituent material of the water-retaining layer has root resistance, the water-retaining layer may also serve as the root-resistant layer.

[0023] The surface layer is a sheet-like member that is placed on the surface of the water-retaining layer and forms the outer surface of the planting base and the planting pockets (described in detail below). The surface layer can be made of a material that is weather-resistant and has sufficient strength and flexibility to form the planting pockets, such as nonwoven fabric or felt. The thickness of the surface layer is not particularly limited and can be set appropriately depending on the strength and other properties of the constituent materials.

[0024] The thickness of the planting base formed by laminating the heat insulating layer, water retaining layer, and surface layer is not particularly limited, but is preferably set to 20 to 60 mm. If the thickness of the planting base is set to be thinner than 20 mm, it becomes difficult to ensure a thickness sufficient for each layer to perform its function, and if it is set to be thicker than 60 mm, the weight of the planting base increases, which increases the weight load on the wall surface and the workload.

[0025] The planting pockets are used to plant plants between the surface layer and the water-retaining layer. This allows the plants planted in the planting pockets to root into the water-retaining layer and absorb water while being supported by the surface layer. Planting pockets can be formed by extending a portion of the surface layer toward the user. For example, a horizontal slit is made in a portion of the surface layer with a cutter or the like, and the lower portion of the surface layer, which is divided into upper and lower portions by the slit, is extended toward the user. The term "slit" includes not only linear slits formed by cutting with a cutter or the like, but also groove-like slits formed by cutting out a certain width. The number and size of the planting pockets are not particularly limited and can be determined appropriately depending on the type and number of plants to be planted, the degree of growth, and other factors. Plants can be placed in the planting pockets directly so that their roots grow directly into the water-retaining layer, or they can be placed in a growing medium such as potting soil or sphagnum moss.

[0026] The wall greening structure is constituted by a plurality of the wall greening panels, that is, it is formed by installing a plurality of wall greening panels in accordance with the area and shape of the wall surface to be installed.

[0027] The wall greening structure may include a watering means and a drainage means. The watering means irrigates the planting pockets of each wall greening panel that constitutes the wall greening structure. Any known means can be used for the watering means, and drip tubes for drip irrigation are particularly preferred, as they can directly irrigate each planting pocket.

[0028] The drainage means receives excess water leaking from the wall greening panel when the irrigation means provides excessive water and drains it to the outside. The drainage means may be any means capable of performing this function, and may be, for example, a gutter provided below the wall greening panel.

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Example]

[0030] [Wall greening panels] Fig. 1 shows a wall greening panel 1 according to an embodiment, and Fig. 2 shows a cross-sectional view of the wall greening panel 1. As shown in Fig. 1, the wall greening panel 1 includes a support plate 10, a planting base 20, and a frame 30.

[0031] The support plate 10 is a plate-like member measuring 40 cm long and 60 cm wide, and is made of an aluminum composite plate in which 0.5 mm thick aluminum plates are attached to both sides of a 2.0 mm thick core material made of foamed polyethylene.

[0032] As shown in Figure 2, the planting base 20 is composed of a laminated insulating layer 21, a water-retaining layer 23, and a surface layer 24, and is provided with planting pockets 24. The insulating layer 21 is made of a 12 mm thick short-fiber nonwoven fabric formed by needle-punching short-fiber polyester and fused fiber blend cotton, and has heat insulation properties as well as water retention and elasticity.

[0033] The root-resistant layer 22 is placed on the surface of the heat-insulating layer 21 and is made of multiple layers of long-fiber nonwoven fabric made of polyester, with a thickness of 0.4 mm. The water-retaining layer 23 is placed on the surface of the root-resistant layer 22 and is made of multiple layers of short-fiber nonwoven fabric made of polyester-blended cotton, which has excellent water absorption and water retention properties, with a thickness of 5.0 mm.

[0034] The surface layer 24 is placed on the surface of the water-retaining layer 23 and constitutes the outermost surface of the planting base 20. The surface layer 24 is made up of multiple layers of short-fiber nonwoven fabric made from recycled polyester, and its thickness is set to 5.0 mm. The surface layer 24 is also decorated with a three-color mixed color scheme so that the wall greening panel 1 blends with the surrounding scenery when installed on a wall.

[0035] The planting pocket 24 is formed by forming a slit 24a extending horizontally in part of the surface layer 24, and when a lower portion 24b of the surface layer 24, which is divided into upper and lower portions at the slit 24, is pulled out, a gap is formed between the surface layer 24 and the water retaining layer 23, and four planting pockets are formed on the wall greening panel 1. A plurality of staples (not shown) are driven into the periphery of each planting pocket 24 by a stapler, which separates adjacent planting pockets 24 and prevents the surface layer 24 from expanding more than necessary when plants are planted.

[0036] The planting base 20 thus formed has the insulating layer 21 abutting against the surface of the support plate 10, and is fixed integrally to the support plate 10 by a pair of left and right frames 30. As shown in Figure 1, the frame 30 has a side abutment surface 31, a front abutment portion 32, and a back abutment portion 33, and is formed in a roughly U-shape when viewed from the end. The frame 30 is attached so as to sandwich the left and right side edges of the support plate 10 and the planting base 20.

[0037] The side contact portion 31 forms a surface that contacts the support plate 10 and the side of the planting base 20. The front surface contact portion 32 is provided extending vertically from one of the longitudinal end faces of the side surface contact portion 31 toward the front surface side of the surface layer 24, and forms a surface that contacts the front surface layer 24. The back surface contact portion 33 is provided extending vertically from the other longitudinal end face of the side surface contact portion 31 toward the back surface side of the support plate 10, and forms a surface that contacts the back surface of the support plate 10.

[0038] The frame 30 thus formed is arranged so that the left and right peripheral edges of the support plate 10 and planting base 20 are accommodated within the roughly U-shaped interior in end view formed by the side abutment portion 31, the surface abutment portion 32, and the back abutment portion 33, and is fixed by tightening bolts and nuts (not shown) that pass through the surface abutment portion 32, planting base 20, support plate 10, and back abutment portion 31. In addition, near the four corners of the wall greening panel 1, through-holes 1a are drilled through which bolts for attaching brackets 40, which will be described in detail later, can be inserted.

[0039] 3 to 7 show brackets 40A, 40B, and 40C as fixing means 40 for fixing the wall greening panel 1 to a wall surface. FIG. 3 shows bracket 40A, which is a first embodiment of bracket 40. Bracket 40A is formed by bending a stainless steel metal plate, and includes a wall fixing portion 41 that is fixed to the wall surface W on which the wall greening panel 1 is to be installed, a panel fixing portion 42 that is fixed to the back surface of the wall greening panel 1, and a connecting portion 43 that is interposed between the upper end of wall fixing portion 41 and the lower end of panel fixing portion 42. Furthermore, hole portions 41a and 42a are drilled in wall fixing portion 41 and panel fixing portion 42, through which bolts are inserted to fix them to the wall surface W and the wall greening panel 1, respectively.

[0040] Fig. 4 shows the wall greening panel 1 installed on a wall W using a bracket 40A. As shown in Fig. 4, the bracket 40A is disposed between the wall greening panel 1 and the wall W. That is, the wall fixing portion 41 of the bracket 40A is fixed to the wall W by an anchor bolt B1 inserted into the wall W through a hole 41a, and the wall fixing portion 42 is fixed to the wall greening panel 1 by tightening nuts N on both ends of a stud bolt B2 inserted into the hole 42a and the through-hole 1a in the wall greening panel 1. In a similar manner, when a bracket 40A is disposed near each of the four corners of the wall greening panel 1, the wall greening panel 1 is installed on the wall W.

[0041] FIG. 5 shows a second embodiment of a bracket 40B. The bracket 40B is configured to secure two adjacent wall greening panels 1 in the width direction. Like the bracket 40A, the bracket 40B includes a wall-mounted fixing portion 41, a panel-mounted fixing portion 42, and a connecting portion 43. However, the bracket 40B differs in that the wall-mounted fixing portion 41 and the panel-mounted fixing portion 42 are formed separately and that two holes 46a are drilled in the panel-mounted fixing portion 42. Therefore, this section will focus on the differences from the bracket 40A, and will not cover the common components. The wall-mounted fixing portion 41 is generally inverted L-shaped in side view and includes a fixing surface 44 that is fixed to the wall W and a first connecting surface 45 that extends vertically from the upper end of the fixing surface 44. A hole 44a is drilled in the approximate center of the fixing surface 44, through which an anchor bolt B1 for fixing the bracket to the wall W is inserted. The panel fixing portion 42 is formed in a generally L-shape in side view and includes a fixing surface 46 that is fixed to the back surface of the wall greening panel 1 and a second connecting surface 47 that extends vertically from the lower end of the fixing surface 46. Two holes 46a, through which stud bolts B2 for fixing to the back surface of the wall greening panel 1 are inserted, are drilled in the fixing surface 46 at a predetermined interval in the width direction.

[0042] A hole 45a and a hole 47a through which a stud bolt B3 is inserted are drilled approximately at the center of the first connection surface 45 of the wall surface fixing part 41 and the center of the second connection surface 47 of the panel fixing part 42. That is, by inserting the stud bolt B3 into the hole 45a and the hole 47a and tightening both ends with nuts N, the first connection surface 45 and the second connection surface 47 are integrated to form the connection part 43.

[0043] Fig. 6 shows two wall greening panels 1 installed on a wall W using bracket 40B. As shown in Fig. 6, after anchor bolts B1 are inserted into holes 45a to secure wall fixing portion 41 to wall W, stud bolts B2 are inserted into two holes 46a in panel fixing portion 42 and into adjacent through holes 1a in the two wall greening panels 1, and then both ends are tightened with nuts N, thereby attaching two wall greening panels 1 adjacent to one bracket 40B. This reduces the amount of work required to fix the panels to wall W compared to bracket 40A.

[0044] FIG. 7 shows a third embodiment of a bracket 40C. The bracket 40C is similar to the bracket 40B in that the wall fixing portion 41 and the panel fixing portion 42 are formed separately. However, the panel fixing portion 42 is configured to fix four wall greening panels 1 adjacent to each other in both the vertical and horizontal directions. Therefore, here, we will focus on the differences from the bracket 40B, and will not discuss the common features. The panel fixing portion 42 includes a fixing surface 46 that is fixed to the rear surface of the wall greening panel 1, a second connecting surface 47 that protrudes vertically from the approximate center of the fixing surface 46, and a vertical surface 48. The fixing surface 46 has four holes 46a, two at a time in the vertical and horizontal directions, drilled at predetermined intervals. Stud bolts B2 are inserted through the holes 46a to fix the bracket 40C to the rear surface of the wall greening panel 1. That is, by inserting a stud bolt B2 into each of the four hole portions 46a and into each of the through holes 1a in the wall greening panels 1 installed adjacently in the vertical and horizontal directions and tightening both ends with nuts N, four wall greening panels 1 can be attached adjacently in the vertical and horizontal directions to one bracket 40C. The second connection surface 47 is formed to be longer than the second connection surface 47 in the bracket 40B, and is fastened to the first connection surface 45 of the wall surface fixing part 41 by a stud bolt B3 to form the connection part 43. The vertical surface 48 is provided to reinforce the second connection surface 47, and is formed on one side end of the second connection surface 47.

[0045] By using brackets 40A, 40B, and 40C for the fixing means 40, the wall greening panel 1 can be installed directly on the wall. In particular, by using brackets 40B and 40C, two or four wall greening panels 1 can be fixed to one bracket 40B or 40C, thereby reducing the burden of installation.

[0046] The wall greening panel 1 described above provides an insulating layer 21 on the surface of the planting base 20 that contacts the support 10, thereby reducing the transfer of heat from the wall W to the planting base 20. This prevents the internal temperature of the planting base 20 from rising, preventing temperature changes from impeding the growth of plants planted in the planting pockets. Furthermore, the support plate 10 is made of aluminum composite board, and the insulating layer 21, water-retaining layer 23, and surface layer 24 of the planting base 20 are made of nonwoven fabric, resulting in a lightweight construction. This reduces the weight load on the wall W during installation, allowing for safe installation on high-altitude walls. The installation effort is also reduced, resulting in low-cost construction and a shorter construction period. Furthermore, the thin design allows the panel to be cut to any shape, allowing it to be installed on walls near entrances and windows, for example, by cutting it to a shape that avoids these obstacles.

[0047] [Green wall structure] 8 to 10 show a wall greening structure 100 according to an embodiment. The wall greening structure 100 is formed by using the wall greening panel 1 described in detail above as a structural unit. Therefore, a description of the specific configuration of the wall greening panel 1 will be omitted here.

[0048] figure 8 and 9, the wall greening structure 100 is configured by fixing two or more wall greening panels 1 to a wall W, and in an area 100a of the wall greening structure 100 shown in FIG. 8, plants P planted in planting pockets 24 are thriving, greening the wall W. The two or more wall greening panels 1 are fixed adjacent to each other to the wall W by brackets 40A as fixing means 40. Of the two or more wall greening panels 1, the wall greening panel 1E installed on the wall W near the upper edge of the triangular shape of the home base-shaped entrance / exit E is cut into a shape that follows the upper edge of the triangle so as not to cover the entrance / exit E.

[0049] The wall greening structure 100 also includes irrigation means 110 and drainage means 120. As shown in FIGS. 9 and 10 , the irrigation means 110 irrigates plants P planted in the wall greening panel 1 and is configured for drip irrigation in this embodiment. The irrigation tubes 111 are made of polyethylene resin and connected to a water supply device (not shown) that controls the irrigation time and the amount of water delivered. The irrigation tubes 111 are arranged so as to run along the periphery of the multiple wall greening panels 1. The irrigation tubes 111 are provided with multiple drip holes (not shown) at predetermined intervals, through which water passing through the tubes leaks. A drip tube 112 is attached to each of the multiple drip holes. The drip tubes 112 are attached to the irrigation tube 111 by inserting a connector (not shown) at one end into the drip hole, and the tip is placed in the planting pocket 24. That is, the drip tubes 112 attached to the irrigation tubes 111 distribute water passing through the irrigation tubes 111 to each planting pocket 24, thereby irrigating the plants. The water supplied to the planting pockets 24 is absorbed by the plants, and the excess water is retained inside the planting base 20, including in the water-retaining layer 23.

[0050] The drainage means 120 receives excess water, including rainwater and water irrigated to each planting pocket 24 by the irrigation means 110, that cannot be retained within the planting base 20 of the wall greening panel 1 and leaks out, and drains the excess water to a designated location such as a drainage ditch. As shown in FIGS. 9 and 10 , the drainage means 120 is disposed below the lowest wall greening panel 1A of the wall greening structure 100 and includes a gutter 121, a drainage hose 122, and an attachment 123. The gutter 121 is an elongated member that is generally concave in side view and has a drain outlet (not shown) at one end. The drainage hose 122 is connected to the drain outlet and drains excess water collected in the gutter 121 to the outside. The attachment 123 is formed by extending one side wall of the gutter 121 further upward and is fixed to the wall W with anchor bolts B1 together with the bracket 40 to which the wall greening panel 1A is attached. In this way, excess water leaking from each wall surface greening panel 1 is collected by the drainage means 120 disposed at the bottom and drained into a drain or the like.

[0051] The wall greening structure 100, which is comprised of the wall greening panels 1, places little weight on the wall W, allowing for safe installation even at high altitudes. The reduced installation workload allows for low-cost construction and a shorter construction period. Furthermore, the wall greening structure 100 can be installed around entrances, windows, signs, and other wall features, avoiding these obstacles, allowing for thorough greening of the entire wall W. The heat-insulating layer 21 included in the wall greening panel 1 not only reduces the transfer of heat from the wall W to the planting base 20 but also reduces the temperature rise of the wall due to sunlight, etc., thereby maintaining a comfortable building temperature. The irrigation means 110 ensures sufficient irrigation for planted plants, providing a favorable growth environment. The drainage means 120 allows for the collection and disposal of excess water into drains or other drainage channels.

[0052] The present invention is not limited to the above-described embodiments, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of rights.

[0053] For example, in the planting base 20, the heat insulating layer 21, the water retaining layer 23, and the surface layer 24 are Different functions Additional layers may be added.

[0054] The irrigation means 110 does not necessarily have to include both the irrigation tubes 111 and the drip tubes 112, and may be configured with only the irrigation tubes 111. Furthermore, irrigation may be performed not only on the planting pockets 24 but also on the inside of the planting base 20, such as the heat insulating layer 21 and the water retaining layer 23. Furthermore, known irrigation means other than means using the irrigation tubes 111 (so-called drip irrigation) may also be used.

[0055] The drainage means 120 may be placed not only at the bottom of the wall greening structure 100, but also in an appropriate location depending on the leakage situation of excess water, etc., and is not limited to the form of a gutter 121, but may be any means that has the function of receiving and discharging excess water. [Industrial Applicability]

[0056] It is lightweight and thin, equipped with a support plate and a planting base, and can be adapted for use as a wall greening system by planting plants in the planting pockets and installing it on the wall of a building or the like. [Explanation of symbols]
