Summary of the Invention

Problems to be Solved by the Invention

[0004] On the other hand, in recent years, the temperature rise in summer has been remarkable, and the outer wall temperature of buildings often becomes high in combination with receiving direct sunlight. Then, when directly greening the wall surface using the greening surface forming member of Patent Document 1, the greening surface forming member may be heated by the heat stored in the wall surface, and the growth of the planted plants may be inhibited and eventually die.

[0005] Therefore, the object of the present invention is to provide a wall greening panel and a wall greening structure that can grow plants 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] To solve the above problems, the first means adopted by the present invention is a support plate and a planting base provided on the surface of the support plate. A wall greening panel having fixing means for fixing to a wall surface, The planting base comprises an insulating layer in contact with the surface of the support plate, a water-retaining layer that holds moisture supplied from the outside and allows plants to take root, a root-resistant layer placed between the insulating layer and the water-retaining layer to prevent plant roots from penetrating the insulating layer, and a surface layer placed on the surface of the water-retaining layer and forming planting pockets between it and the water-retaining layer into which plants are planted. The fixing means comprises a wall fixing portion attached to the wall surface and a panel fixing portion attached to the back of the support plate, with through holes drilled near the four corners of the support plate and the planting base, and the panel fixing portion having two holes drilled at predetermined intervals along at least one of the vertical and horizontal directions, and is attached to the back of the support plate by inserting a bolt through one of the holes and one of the through holes and tightening it with a nut, and is also attached to the back of the support plate of the other wall greening panel by inserting a bolt through the other hole and one of the through holes in another wall greening panel adjacent to the wall greening panel and tightening it with a nut. These are wall-mounted greening panels.

[0007] In the wall greening panel of the present invention, an insulating layer is placed on the side of the planting base that is in contact with the support plate. This way, when the wall greening panel is attached to the wall of a building, the insulating layer is interposed between it and the wall, reducing the rise in the internal temperature of the planting base caused by heat emitted from the wall. Furthermore, since the planting pockets into which plants are planted are formed from voids created between the water retention layer and the surface layer, a separate component for planting is not required, allowing the wall greening panel to be manufactured to be lightweight, and enabling the planted plants to directly root in the water retention layer and absorb water.

[0008] In this specification and in the claims, "building" includes not only buildings where people come and go, such as office buildings, houses, and shops, but also walls and slopes, and "wall" includes not only the walls that make up the interior and exterior surfaces of the above-mentioned building, but also flat surfaces such as the roof of the building.

[0009] The planting pocket may consist of a void formed between the water-retaining layer and the lower portion of a horizontally elongated cut provided in the surface layer when that portion is pulled out.

[0010] This creates a planting pocket with sufficient volume for planting.

[0011] Furthermore, the second method employed by the present invention is, The wall greening panels are configured by fixing multiple panels to the wall surface using the aforementioned fixing means. It is a wall-mounted greening structure.

[0012] The wall greening structure of the present invention is constructed by combining multiple wall greening panels that are fixed to the wall surface via fixing means. This makes it possible to directly green any area of ​​the wall surface of a building or the like.

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

[0014] The irrigation system provides water to the entire wall greening structure, ensuring a stable water supply to each wall greening panel. Furthermore, the drainage system collects any excess water that overflows from the wall greening panels, preventing water from dripping around the structure and directing it to designated drainage channels. [Effects of the Invention]

[0015] According to the wall greening panel and wall greening structure of the present invention, an insulating layer is provided on the side of the planting base that is in contact with the support, thereby reducing the transfer of heat emitted from the wall to the planting base. As a result, the temperature inside the planting base does not rise easily, preventing the growth of plants planted in the planting pockets from being inhibited by the effects of temperature changes. Furthermore, since the planting pockets are formed from the void created between the water-retaining layer and the surface layer without using separate components, they are made to be lightweight. As a result, the weight load on the wall is reduced, so they can be safely installed on walls at high places, and the cost and burden of construction can be reduced.

Mode for Carrying Out the Invention

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

[0018] The wall greening panel includes a support plate and a planting base. The support plate is a plate-like member that serves as the framework of the wall greening panel. For example, it can be made of metal, resin, gypsum, wood, or a composite material thereof, and can be made of a lightweight plate material with rigidity that does not easily bend. The thickness of the support plate is not particularly limited and can be appropriately set according to the properties of the material, but it is preferably set to a thickness that is necessary and sufficient to maintain rigidity without being excessively thick.

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

[0020] The planting base is a component in a wall greening panel on which plants are planted and grown. The planting base is placed on the surface of the support plate and consists of an insulating layer, a root-resistant layer, a water-retaining layer, and a surface layer. The insulating layer is the layer that makes up the surface of the planting base that is in 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 transferred to the interior. Known insulating materials such as fibrous or foamed plastic can be used for the insulating layer, but nonwoven fabric insulating material is particularly preferable because it adds buffering and water-retaining properties to the insulating effect, thereby improving its functionality.

[0021] The water retention layer is a sheet- or plate-like component placed between the insulation layer and the water retention layer, which retains moisture absorbed by plants planted in the planting pockets (described in detail later) and allows the plants to take root. The water retention layer can be made of a material with excellent water absorption and retention properties, such as a sheet of porous material like nonwoven fabric, felt, urethane, or sponge. The thickness of the water retention layer is not particularly limited and can be set appropriately according to the water retention properties of the constituent materials and the water absorption capacity of the plants to be planted.

[0022] The root-tolerant layer is a layer that controls the rhizome area to prevent plant roots that have grown in the water-retaining layer from penetrating the insulation layer. The root-tolerant layer can be made from a sheet of resin fibers such as polyester or polypropylene, woven or molded at high density. The thickness of the root-tolerant layer is not particularly limited, as long as sufficient root-tolerance performance is ensured to prevent plant roots from penetrating the insulation layer. Furthermore, if the constituent material of the water-retaining layer also possesses root-tolerant properties, the water-retaining layer and the root-tolerant layer may be used interchangeably.

[0023] The surface layer is a sheet-like member placed on the surface of the water-retaining layer, forming the outer surface of the planting base and the planting pockets, which will be described in detail later. The surface layer can be made of a material that has excellent weather resistance as well as 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 according to the properties such as the strength of the constituent material.

[0024] The thickness of the planting base, which consists of the above-mentioned insulation layer, water-retaining layer, and surface layer, is not particularly limited, but it is preferably set to 20 to 60 mm. If the thickness of the planting base is set to less than 20 mm, it becomes difficult to ensure sufficient thickness for each layer to perform its function, and if it is set to more than 60 mm, the weight of the planting base increases, increasing the weight load on the wall and the workload.

[0025] A planting pocket is a structure in which plants are planted between the surface layer and the water-retaining layer. This allows plants planted in the planting pocket to be held in place by the surface layer while their roots extend into the water-retaining layer and absorb water. A planting pocket can be formed by pulling out a portion of the surface layer towards the front. For example, a horizontal cut can be made in a portion of the surface layer with a cutter, and the lower portion of the surface layer, divided into upper and lower halves, can be pulled out from the cut towards the front. Note that the "cut" includes not only linear cuts formed by cutting with a cutter, but also groove-like cuts formed by cutting out a wide section. The number and size of planting pockets are not particularly limited and can be set appropriately according to the type and number of plants to be planted, the degree of their growth, etc. Furthermore, plants may be placed directly in the planting pocket so that their roots extend directly into the water-retaining layer, or a growing medium such as soil or sphagnum moss may be placed in the pocket before the plants are placed inside.

[0026] A wall greening structure is composed of multiple wall greening panels; that is, it is formed by installing multiple wall greening panels to match the area and shape of the wall surface on which it is to be installed.

[0027] The wall greening structure may include irrigation means and drainage means. The irrigation means provides water to the planting pockets of each wall greening panel that constitutes the wall greening structure. Known means can be used for the irrigation means, and in particular, the use of drip tubes for so-called drip irrigation is preferred because it allows for direct watering to each planting pocket.

[0028] The drainage means is used to collect excess water that leaks from the wall greening panels when the irrigation by the above-mentioned irrigation means becomes excessive, and to drain it to the outside. The drainage means can be anything that can perform this function, for example, it can be a gutter installed below the wall greening panels.

[0029] The embodiments of the present invention will be described below with reference to the figures. [Examples]

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

[0031] The support plate 10 is a plate-shaped member measuring 40 cm in length and 60 cm in width, and is made of an aluminum composite plate in which a 2.0 mm thick core material made of foamed polyethylene is bonded to both sides with 0.5 mm thick aluminum plates.

[0032] As shown in Figure 2, the planting base 20 is constructed by laminating an insulating layer 21, a water-retaining layer 23, and a surface layer 24, and is equipped 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 blended cotton, and has insulating 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 consists 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 consists of multiple layers of short-fiber nonwoven fabric made of polyester blend 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 of recycled polyester, and its thickness is set to 5.0 mm. In addition, the surface layer 24 has a three-color mixed color scheme so that it harmonizes with the surrounding landscape when the wall greening panel 1 is installed on the wall.

[0035] Each planting pocket 24 consists of a gap formed between the water-retaining layer 23 and the lower portion 24b of the surface layer 24, which is divided into upper and lower sections by a lateral cut 24a in a part of the surface layer 24. Four planting pockets are formed in the wall greening panel 1. Multiple staples (not shown) are driven around the perimeter of each planting pocket 24 using a tacker, partitioning the space between adjacent planting pockets 24 and preventing the surface layer 24 from expanding excessively when plants are planted.

[0036] The planting base 20 thus formed has a heat insulating layer 21 that abuts against the surface of the support plate 10, and is integrally fixed 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 contact surface 31, a front contact portion 32, and a back contact portion 33, and is formed in a roughly U-shape when viewed from the end face, and 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 side of the support plate 10 and the planting base 20. The surface contact portion 32 is provided extending vertically from one of the longitudinal end faces of the side contact portion 31 toward the surface side of the surface layer 24, and forms a surface that contacts the surface layer 24. The back contact portion 33 is provided extending vertically from the other longitudinal end face of the side contact portion 31 toward the back side of the support plate 10, and forms a surface that contacts the back 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 the planting base 20 are housed within the roughly U-shaped end face formed by the side contact portion 31, the front contact portion 32, and the back contact portion 33, and is fixed by tightening bolts and nuts (not shown) that pass through the front contact portion 32, the planting base 20, the support plate 10, and the back contact portion 31. In addition, through holes 1a are drilled near the four corners of the wall greening panel 1, through which bolts for attaching brackets 40, which will be described in detail later, are inserted.

[0039] Figures 3 to 7 show brackets 40A, 40B, and 40C, which serve as fixing means 40 for fixing the wall greening panel 1 to the wall. Figure 3 shows bracket 40A, which is the first form of bracket 40. Bracket 40A is formed by bending a metal plate made of stainless steel and includes a wall fixing part 41 that is fixed to the wall W on which the wall greening panel 1 is installed, a panel fixing part 42 that is fixed to the back of the wall greening panel 1, and a connecting part 43 interposed between the upper end of the wall fixing part 41 and the lower end of the panel fixing part 42. Furthermore, the wall fixing part 41 and the panel fixing part 42 are provided with holes 41a and 42a through which bolts are inserted to fix them to the wall W and the wall greening panel 1, respectively.

[0040] Figure 4 shows the wall greening panel 1 installed on the wall W using bracket 40A. As shown in Figure 4, bracket 40A is positioned between the wall greening panel 1 and the wall W. Specifically, the wall fixing portion 41 of bracket 40A is fixed to the wall W by anchor bolts B1 inserted into the wall W through hole 41a, and the wall fixing portion 42 is fixed to the wall greening panel 1 by tightening nuts N on both ends of stud bolts B2 inserted through hole 42a and through hole 1a in the wall greening panel 1. Similarly, when brackets 40A are positioned near each of the four corners of the wall greening panel 1, the wall greening panel 1 is installed on the wall W.

[0041] Figure 5 shows the second form, bracket 40B. Bracket 40B is formed to fix two wall greening panels 1 adjacent to each other in the width direction, and like bracket 40A, it has a wall fixing part 41, a panel fixing part 42, and a connecting part 43, but differs in that the wall fixing part 41 and the panel fixing part 42 are formed separately and two holes 46a are drilled in the panel fixing part 42. Therefore, the differences from bracket 40A will be described in detail here, and the common components will not be explained. The wall fixing part 41 is formed in a roughly inverted L shape in side view, comprising 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. The fixing surface 44 has a hole 44a drilled in the approximate center through which an anchor bolt B1 for fixing to the wall W is inserted. The panel fixing portion 42 is formed in a substantially L-shape in side view, comprising a fixing surface 46 fixed to the back of the wall greening panel 1 and a second connecting surface 47 extending vertically from the lower end of the fixing surface 46. The fixing surface 46 has two holes 46a through which stud bolts B2 for fixing to the back of the wall greening panel 1 are inserted, spaced at a predetermined distance in the width direction.

[0042] Holes 45a and 47a are drilled approximately in the center of the first connecting surface 45 of the wall fixing part 41 and approximately in the center of the second connecting surface 47 of the panel fixing part 42, respectively, through which stud bolts B3 are inserted. That is, by inserting stud bolts B3 through holes 45a and 47a and tightening both ends with nuts N, the first connecting surface 45 and the second connecting surface 47 are integrated to form a connecting part 43.

[0043] Figure 6 shows two wall greening panels 1 installed on a wall W using bracket 40B. As shown in Figure 6, after fixing the wall fixing part 41 to the wall W by inserting anchor bolts B1 through holes 45a, stud bolts B2 are inserted through two holes 46a in the panel fixing part 42 and through holes 1a located adjacent to each other in the two wall greening panels 1, and both ends are tightened with nuts N, thereby allowing two wall greening panels 1 to be attached adjacent to each other on one bracket 40B. In this way, the work required to fix to the wall W can be reduced compared to bracket 40A.

[0044] Figure 7 shows a third form of bracket 40C. Bracket 40C is similar to bracket 40B in that the wall fixing part 41 and the panel fixing part 42 are formed separately, but it differs in that the panel fixing part 42 is formed to fix four wall greening panels 1 adjacent to each other in the vertical and horizontal directions. Therefore, the differences from bracket 40B will be described in detail here, and the common configuration will not be explained. The panel fixing part 42 has a fixing surface 46 that is fixed to the back of the wall greening panel 1, and a second connecting surface 47 and a vertical surface 48 that protrude vertically from approximately the center of the fixing surface 46. Four holes 46a are drilled in the fixing surface 46, two in the vertical direction and two in the horizontal direction at predetermined intervals, through which stud bolts B2 for fixing to the back of the wall greening panel 1 are inserted. In other words, by inserting stud bolts B2 through each of the four holes 46a and each of the through holes 1a in the wall greening panels 1 that are installed adjacent to each other in the vertical and horizontal directions, and tightening both ends with nuts N, four wall greening panels 1 can be attached to one bracket 40C adjacent to each other in the vertical and horizontal directions. The second connecting surface 47 is formed to be longer than the second connecting surface 47 on the bracket 40B, and is fastened to the first connecting surface 45 of the wall fixing part 41 by stud bolts B3 to form a connecting part 43. The vertical surface 48 is provided to reinforce the second connecting surface 47 and is formed at one end of the second connecting surface 47.

[0045] By using brackets 40A, 40B, and 40C with the fixing means 40, the wall greening panel 1 can be directly installed 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, thus reducing the burden of construction.

[0046] According to the above-described wall greening panel 1, an insulating layer 21 is provided on the side of the planting base 20 that is in contact with the support 10, thereby reducing the transfer of heat emitted from the wall W to the planting base 20. As a result, the internal temperature of the planting base 20 does not rise easily, preventing the growth of plants planted in the planting pockets from being inhibited by the effects of temperature changes. Furthermore, by using an aluminum composite panel for the support plate 10 and nonwoven fabric for the insulating layer 21, water retention layer 23, and surface layer 24 that constitute the planting base 20, it can be formed to be lightweight. As a result, the weight load on the wall W when installed is reduced, so it can be safely installed on walls at high places, and the burden of installation work is also reduced, enabling low-cost construction and a shorter construction period. Moreover, because it is formed to be thin, it can be cut into any shape, so for example, even on walls near doorways and windows, it can be cut into a shape that avoids these and installed.

[0047] [Wall greening structure] Figures 8 to 10 show a wall greening structure 100 according to an embodiment. The wall greening structure 100 is formed using the wall greening panels 1 described in detail above as constituent units. Therefore, a detailed explanation of the specific configuration of the wall greening panels 1 will be omitted here.

[0048] figure As shown in Figures 8 and 9, the wall greening structure 100 is constructed by fixing two or more wall greening panels 1 to the wall W. In the area 100a of the wall greening structure 100 shown in Figure 8, the wall W is greened by the thriving plants P planted in the planting pockets 24. The two or more wall greening panels 1 are fixed adjacent to each other to the wall W by brackets 40A, which serve as fixing means 40. Furthermore, among the two or more wall greening panels 1, the wall greening panel 1E installed on the wall W near the triangular upper edge of the entrance E, which is formed in the shape of a home plate, is a rectangular wall greening panel 1 that has been cut to a shape that follows the triangular upper edge so as not to overlap the entrance E.

[0049] Furthermore, the wall greening structure 100 includes an irrigation means 110 and a drainage means 120. As shown in Figures 9 and 10, the irrigation means 110 irrigates the plants P planted on the wall greening panel 1, and in this embodiment, it is configured to perform so-called drip irrigation. The irrigation tube 111 is made of polyethylene resin and is connected to a water supply device (not shown) that controls the irrigation time and the amount of water delivered, and is arranged to crawl along the periphery of the multiple wall greening panels 1. The irrigation tube 111 is provided with multiple drip holes (not shown) at predetermined intervals, and water passing through the inside leaks out from here. A drip tube 112 is attached to each of these multiple drip holes. The drip tube 112 is attached to the irrigation tube 111 by inserting a connector (not shown) provided at one end into the drip hole, and the tip is placed in the planting pocket 24. In other words, water passing through the irrigation tube 111 is distributed to each planting pocket 24 by a drip tube 112 attached to the irrigation tube 111, thereby irrigating the plants. The water supplied to the planting pockets 24 is absorbed by the planted plants, and any excess water is retained inside the planting base 20, including the water retention layer 23.

[0050] The drainage means 120 receives excess water that leaks out of the planting base 20 of the wall greening panel 1, which is watered into each planting pocket 24 by the irrigation means 110 or rainwater, and drains it to a predetermined location such as a drainage ditch. As shown in Figures 9 and 10, the drainage means 120 is located below the wall greening panel 1A, which is at the bottom of the wall greening structure 100, and comprises a gutter 121, a drainage hose 122, and a mounting part 123. The gutter 121 is an elongated member that is roughly concave in side view, and has a drainage port (not shown) at one end. The drainage hose 122 is connected to the drainage port and drains the excess water collected by the gutter 121 to the outside. The mounting part 123 is formed by extending one side wall of the gutter 121 further upward and is fixed to the wall W by anchor bolts B1 together with the bracket 40 to which the wall greening panel 1A is attached. In this way, any excess water leaking from each wall greening panel 1 is collected by the drainage means 120 located at the bottom and drained into a drainage ditch or the like.

[0051] According to the above-described wall greening structure 100, since it is composed of the above-described wall greening panel 1, the weight load on the wall W is reduced, and it can be safely installed even at high places. In addition, the burden of installation work is also reduced, making it possible to carry out construction at a low cost and shorten the construction period. Furthermore, even on wall areas where entrances, windows, signs, etc. are installed, it is possible to install the structure while avoiding these, so the entire wall W can be greened. In addition, the heat insulation layer 21 included in the wall greening panel 1 not only makes it difficult for heat emitted from the wall W to be transferred to the planting base 20, but also reduces the temperature rise of the wall surface due to sunlight, etc., so the room temperature of the building can be kept at a comfortable temperature. Furthermore, since it is equipped with an irrigation means 110, the planted plants can be adequately irrigated and provided with a good growing environment. Furthermore, since it is equipped with a drainage means 120, excess water that leaks out can be collected and drained into a drainage ditch, etc.

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

[0053] For example, in the planting base 20, the insulating layer 21, the water retention layer 23, and the surface layer 24 are Different functions You can add another layer.

[0054] The irrigation means 110 does not necessarily need to include both the irrigation tube 111 and the drip tube 112, and may consist only of the irrigation tube 111. Furthermore, irrigation may be performed not only on the planting pockets 24, but also on the interior of the planting base 20, such as the insulation layer 21 and the water retention layer 23. In addition, known irrigation means other than those using the irrigation tube 111 (so-called drip irrigation) may also be used.

[0055] The drainage means 120 can be placed not only at the very bottom of the wall greening structure 100, but also at other appropriate locations depending on the leakage of excess water, and is not limited to the form of a gutter 121; any means that has the function of receiving and discharging excess water can be used. [Industrial applicability]

[0056] Equipped with a support plate and a planting base, it is lightweight and thin, and by planting plants in the planting pockets and installing it on the wall surface of buildings, it can be adapted for use in greening walls. [Explanation of symbols]
