Various types of ground cover plant protection plates of this type are known (see, for example, Patent Documents 1-7). Among them, for example, in the protection plate disclosed in Japanese Patent Laid-Open No. 5-316882, a stepping pressure cylinder is provided in an upright manner at each intersection of the lattice-like substrate portion.
JP-A-5-316882 JP 2007-29051 A Japanese Patent No. 3842715 JP-A-5-68438 Japanese Utility Model Publication No. 6-72345 Japanese Patent No. 3055979 Japanese Patent Laid-Open No. 5-23061

  Thus, in the conventional protective plate, for example, there is a problem that the supporting column portion such as the stepping cylinder is broken due to a load at the start or stop of the automobile.

  The present invention has been made in view of the above-described technical background, and an object thereof is to increase the strength of a support portion that supports a heavy object on a ground surface of a ground cover plant from below, and further, a ground cover plant. It is to provide a ground cover protection plate that is easy to breed.

  The present invention provides the following means.

[1] A plurality of struts having the same height are erected regularly along each of the streaks of the net-like substrate part,
At least the upper portions of the plurality of support columns adjacent to each other at the intersections between the streaks of the substrate unit are connected to each other by the first connecting rib portions, thereby forming a support column assembly.
The lower portions of the columnar joints adjacent to each other along the streaks of the base plate are coupled to each other by the second connecting ribs formed along the streaks, and are partitioned by the second connecting ribs. A partitioned compartment is formed for each mesh opening of the substrate part,
While the height of the second connecting rib portion is set lower than the height of the support column portion and the first connecting rib portion,
The ground cover plant protection board according to claim 1, wherein a first communication hole that communicates a plurality of adjacent compartments with each other through the first connection rib portion is provided below the first connection rib portion.

  [2] The ground cover plant protection plate according to the above item 1, wherein the height of the first connecting rib portion is set lower than the height of the support column portion.

  [3] The ground cover plant protection plate according to the above item 1 or 2, wherein a concave portion is provided on the lower surface of the intersecting portion of the substrate portion so as to communicate with the first communication hole.

  [4] In any one of the preceding items 1 to 3, wherein a second communication hole that communicates a plurality of adjacent compartments with each other via the second connection rib portion is provided below the second connection rib portion. Ground cover plant protection board of description.

  The present invention has the following effects.

  In the invention of [1], since the heights of the support columns are equal, it is possible to prevent a problem that the load is applied nonuniformly to the support columns due to the different heights of the support columns.

  Further, since the plurality of support columns are connected to each other by the first connecting rib portion, the support assembly is formed, so that the support assembly having higher strength than the single support is formed. be able to. Moreover, since at least the upper portions of the plurality of strut portions are coupled to each other by the first connecting rib portions, the strength of the upper portion of the strut portion combined body is very high.

  Furthermore, since the lower parts of the pillar unit assemblies adjacent to each other along the streaks of the substrate unit are coupled to each other by the second connecting ribs formed along the muscles, each column unit complex is a second unit. Reinforced by the connecting rib portion, this further increases the strength of the support post assembly. As a result, for example, it is possible to prevent a problem that the support column or the support unit combination is broken due to a load at the start or stop of the automobile.

  And the height of the 2nd connection rib part is set lower than the height of a support | pillar part and a 1st connection rib part. Therefore, the stems and the like of the ground cover plant vegetated in each compartment can extend in the lateral direction toward the adjacent compartment through the upper side of the second connecting rib portion. Thereby, it becomes easy to breed ground cover plants.

  In addition, a first communication hole that communicates a plurality of adjacent compartments with each other via the first connection rib portion is provided at a lower portion of the first connection rib portion. Therefore, the stems and roots of the ground cover plants vegetated in the respective compartments can extend in the lateral direction toward the adjacent compartments through the first communication hole. This makes it easier for the ground cover plants to reproduce.

  Of course, since the substrate portion is net-like, water sprayed on the ground cover plant vegetated in the compartment can be discharged from the mesh opening of the substrate portion. That is, the mesh opening of the substrate portion can be used as an outlet for water sprayed on the ground cover plant.

  In the invention of [2], the height of the first connecting rib portion is set to be lower than the height of the column portion. Therefore, when there are pedestrians, vehicles, etc. on the protective plate, the soles of the pedestrians, the wheels of the vehicle, etc. are among the plurality of struts and the first connecting ribs that constitute the struts combined body, Although it contacts the upper surface of the support column, it does not contact the upper surface of the first connecting rib. Therefore, when the pedestrian walks or the vehicle starts / stops, the ground cover leaves are rubbed and cut between the upper surface of the first connecting rib part and the shoe soles, wheels, etc. The problem of being hindered can be eliminated, thereby making it easier for the ground cover plants to reproduce.

  Furthermore, in the protective plate according to the present invention, the first connecting rib portion has a reduced strength due to the provision of the first communication hole in the lower portion thereof. Since the vehicle wheel or the like does not contact the upper surface of the first connecting rib portion, the load from the pedestrian or the vehicle is directly applied to the support column portion and not directly applied to the first connecting rib portion. Thereby, the load added to a 1st connection rib part can be reduced, and therefore the failure | damage of the 1st connection rib part by the load from a pedestrian, a vehicle, etc. can be prevented.

  In the invention of [3], since the concave portion is provided on the lower surface of the intersecting portion of the substrate portion so as to communicate with the first communication hole, the root of the ground cover plant vegetated in the compartment is the first communication hole and the concave portion. Can be extended downwards sequentially. This makes it easier for the ground cover plants to reproduce. Furthermore, the water sprayed on the ground cover plant can be discharged not only from the mesh opening of the substrate portion but also from the opening of the recess through the first communication hole and the recess. Thereby, it is possible to improve drainage.

  In the invention of [4], a second communication hole for communicating a plurality of adjacent compartments with each other via the second connection rib portion is provided in the lower portion of the second connection rib portion. Therefore, the stems and roots of the ground cover plants vegetated in each compartment can extend laterally not only above the second communication rib part but also through the second communication hole toward the adjacent compartment. Become. This makes it easier for the ground cover plants to reproduce.

  Next, several embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 6, the ground cover protecting plate (1) according to the embodiment of the present invention has a lawn (20) planted in a park, a garden, a parking lot, a heliport, a golf course, etc. as a ground cover plant. In order to protect against damage caused by the stepping pressure of heavy objects such as pedestrians and vehicles, the turf (20) is laid on a planting site and used.

  This protective plate (1) is made of hard resin or hard plastic formed by injection molding. As shown in FIGS. 1 and 2, for example, length 600 mm × width 600 mm × height (thickness). The size is about 40 to 60 mm. In the present invention, the size of the protective plate (1) is not limited to the above size, and can be variously changed depending on the laying place.

  The protective plate (1) includes a substrate portion (2) having a lattice shape (square lattice shape in detail) as a net shape, a plurality of support column portions (7), and the like.

  The substrate portion (2) is composed of a plurality of vertical stripe portions (3) and horizontal stripe portions (3) arranged so as to cross each other (in detail, orthogonal). (4) is an intersection where the vertical stripe (3) and the horizontal stripe (3) of the substrate (2) intersect. (5) is a large number of mesh openings in the substrate part (2). Each mesh opening (5) is formed in a square cross section (more specifically, a square cross section), and is used as an outlet for water sprayed on the turf (20).

  In addition, the thickness d of the board | substrate part (2) is set to 5-15 mm, for example, and if set in detail, it is set to 8-12 mm (refer FIG. 4). Moreover, the width | variety of each stripe | line | muscle part (3) is set, for example to 10-35 mm, and if it explains in full detail, it will be set, for example to 15-25 mm. The lengths of the vertical side and the horizontal side of each mesh opening (5) are set to, for example, 15 to 45 mm, and more specifically, for example, 20 to 40 mm.

  A large number of support columns (7) protect heavy objects (not shown) such as pedestrians and vehicles (eg, automobiles) that may exist on the lawn (20) from damage caused by treading of the heavy objects. In order to do so, as shown in FIG. 1 and FIG. 3 to FIG. 5, each streak portion (3) of the substrate portion (2) is regularly arranged along the streak portion (3). They are integrally formed in a standing shape. If it demonstrates concretely, one support | pillar part (7) will be formed in the vicinity of both sides which pinched | interposed each cross | intersection part (4) in each stripe | line | muscle part (3) of a board | substrate part (2).

  The heights of these support columns (7) are set to be equal to each other, and these support columns (7) are cylindrical (and thus circular in cross section) and are formed in the same shape. Specifically, as shown in FIG. 4, the height a of the support column (7) from the upper surface of the substrate (2) is set to 30 to 60 mm, for example. For example, it is set to 35 to 50 mm. Moreover, the diameter of the support | pillar part (7) is set, for example to 5-15 mm, and if it explains in full detail, it will be set, for example to 8-12 mm.

  Moreover, as shown in FIGS. 1 and 3 to 5, the four column portions (7), (7), (7), (7) that are adjacent to each other at the intersections (4) of the substrate portion (2). At least the upper part is integrally connected to each other by the first connecting rib portion (8) having a cross-shaped cross section, whereby the four support columns (7), (7), (7), and (7) are connected to the first connecting rib. The support | pillar part coupling body (9) couple | bonded mutually via the part (8) is formed in each cross | intersection part (4) of a board | substrate part (2). In the present embodiment, the first connecting rib portion (8) is provided with a first insertion hole (12), which will be described later, in the lower portion thereof, and therefore, four strut portions (7) (7) (7) (7) Of the upper and lower portions, only the upper portion is connected to each other by the first connecting rib portion (8).

  The thickness of the first connecting rib portion (8) is set to be equal to or less than the diameter of the support column portion (7), and is set to 2 to 9 mm, for example, and specifically set to 4 to 7 mm. Moreover, the center space | interval of the support | pillar part (7) (7) mutually connected by the 1st connection rib part (8) is set to 15-35 mm, for example.

  The height of the 1st connection rib part (8) is set lower than the height of a support | pillar part (7). In the present invention, the height of the first connecting rib portion (8) is set, for example, 2 to 10 mm lower than the height a of the support column portion (7). That is, in FIG. 4, the height difference b between the column portion (7) and the first connecting rib portion (8) is set to, for example, 2 to 10 mm, and specifically set to, for example, 3 to 7 mm. .

  Furthermore, the lower part of the support | pillar part coupling | bond body (9) which adjoins along each muscle | muscle part (3) of a board | substrate part (2) is integrally formed in the muscle | muscle part (3) along the muscle part (3). The second connecting rib portions (10) are connected to each other. As a result, a compartment (11) having a quadrangular cross section (more specifically, a square cross section) defined by the second connecting rib portion (10) is formed for each mesh opening (5) of the substrate portion (2). ing. The thickness of the second connecting rib portion (10) is set to be equal to or less than the diameter of the support column (7), and in this embodiment, the thickness is set to be the same as the diameter of the support column (7).

  The height of each 2nd connection rib part (10) is set lower than the height of a support | pillar part (7) and a 1st connection rib part (8). When it shows concretely about the height of a 2nd connection rib part (10), as shown in FIG. 4, the height c of a 2nd connection rib part (10) is higher than the height a of a support | pillar part (7). For example, it is set lower by 15 to 30 mm, and more specifically, for example, it is set lower by 17 to 25 mm.

  In the lower part of each first connecting rib portion (8), four compartments (11) (11) (11) (11) adjacent to each other through the first connecting rib portion (8) communicate with each other. One communication hole (12) is provided.

  The method of forming the first communication hole (12) will be described. A cross-sectional circle having a diameter larger than the thickness of the first connection rib portion (8) is formed on the lower surface of each intersection portion (4) of the substrate portion (2). Each of the first communication holes (12) is first formed by forming the concave portion (13) having a shape from the lower surface of the intersecting portion (4) to the depth of the intermediate portion in the height direction of the first connecting rib portion (8). It is formed in the lower part of a connection rib part (8). Therefore, the recess (13) and the first connection hole (12) are in communication with each other. By forming the first communication hole (12) in this way, the first communication hole (12) can be easily formed. The diameter of the recess (13) is set to 10 to 25 mm, for example.

  As shown in FIG. 6, the protection plate (1) of the present embodiment is used by laying a plurality on the ground on which the turf (20) is planted. A crushed stone layer (22) or a sand layer is provided on the lower side of the protective plate (1), thereby enhancing the drainage of water sprayed on the turf (20). In each compartment (11) of the protective plate (1), the soil (21) is placed and the turf (20) is vegetated.

  Thus, the protective plate (1) of the present embodiment has the following advantages.

  That is, as shown in FIG.4 and FIG.5, since the height of the support | pillar part (7) of a protection board (1) is equal, it differs in each support | pillar part (7) because the height of each support | pillar part (7) differs. The trouble that the load is applied unevenly can be prevented.

  Further, as shown in FIGS. 1 and 3, four support columns (7), (7), (7), and (7) adjacent to each other at the intersection (4) of the substrate (2) are connected in the first manner. Since the support column assembly (9) is formed by being coupled to each other by the rib portion (8), the support column assembly (9) having higher strength than the single support column (7) is formed. can do. Moreover, since the upper portions of the four column portions (7), (7), (7), and (7) are coupled to each other by the first connecting rib portion (8), the upper portions of the column portion combined body (9) The strength is very high.

  Further, the lower portions of the support post combined bodies (9) adjacent to each other along the streaks (3) of the substrate section (2) are formed by the second connecting ribs (10) formed along the streaks (3). Since they are connected to each other, each column portion combination (9) is reinforced by the second connecting rib portion (10), thereby further increasing the strength of the column portion combination (9). As a result, for example, it is possible to prevent a problem that the support column (7) and the support assembly (9) are broken due to a load at the start or stop of the automobile.

  And the height c of the 2nd connection rib part (10) is set lower than the height of a support | pillar part (7) and a 1st connection rib part (8). Therefore, the stems (not shown) of the turf (20) vegetated in each compartment (11) pass laterally toward the adjacent compartment (11) through the upper side of the second connecting rib portion (10). It can grow. Thereby, lawn (20) becomes easy to breed.

  In addition, the four compartments (11), (11), (11), and (11) adjacent to each other through the first connecting rib portion (8) communicate with each other at the lower portion of the first connecting rib portion (8). A first communication hole (12) is provided. Therefore, the stems, roots, and the like of the turf (20) vegetated in each compartment (11) can extend laterally through the first communication hole (12) toward the adjacent compartment (11). This makes it easier for the turf (20) to propagate.

  Of course, since the substrate portion (2) is in a lattice shape, water sprayed on the lawn (20) vegetated in the compartment (11) can be discharged from the mesh opening (5) of the substrate portion (2).

  Furthermore, the height of the first connecting rib portion (8) is set to be lower than the height a of the support column portion (7). Therefore, when a pedestrian, a vehicle, etc. exist on a protection board (1), a pedestrian's shoe sole, a vehicle wheel, etc. are four support | pillar parts (7) (7) of a support | pillar part coupling body (9). ) (7) Of the first connecting rib portion (8) and the first connecting rib portion (8), it contacts the upper surface of the column portion (7), but does not contact the upper surface of the first connecting rib portion (8). Therefore, when the pedestrian walks or when the vehicle starts or stops, the leaves of the turf (20) are rubbed and cut between the upper surface of the first connecting rib (8) and the shoe sole, wheels, etc. The problem that the propagation of 20) is hindered can be solved, and this makes it easier for the turf (20) to reproduce.

  Furthermore, in the protection plate (1) of the present embodiment, the strength of the first connecting rib portion (8) is reduced by the amount that the first communication hole (12) is provided in the lower portion. However, as described above, pedestrian shoe soles, vehicle wheels, and the like do not come into contact with the upper surface of the first connecting rib portion (8). ) Directly and not directly to the first connecting rib portion (8). Thereby, the load added to a 1st connection rib part (8) can be reduced, and, thereby, the failure | damage of the 1st connection rib part (8) by the load from a pedestrian, a vehicle, etc. can be prevented.

  Furthermore, since the recessed part (13) is provided in the state connected to the 1st communicating hole (12) in the lower surface of each cross | intersection part (4) of a board | substrate part (2), it vegetated in the compartment (11). The root of the turf (20) can extend downward through the first communication hole (12) and the recess (13) in sequence. This makes it easier for the turf (20) to propagate. Furthermore, the water sprayed on the turf (20) is not only discharged from the mesh opening (5) of the substrate part (2), but is further passed through the first communication hole (12) and the recess (13) sequentially to form the recess ( 13) It is possible to discharge downward from the opening. Thereby, it is possible to improve drainage.

  FIG. 7 is a view showing a ground cover plant protection plate (1) according to another embodiment of the present invention.

  In this protective plate (1), two compartments (11) (11) adjacent to each other are communicated with each other through the second connection rib portion (10) at the lower portion of the second connection rib portion (10). A second communication hole (14) is provided.

  The other structure of this protective plate (1) is the same as the protective plate of the said embodiment.

  According to this protective plate (1), since the 2nd communicating hole (14) is provided in the lower part of the 2nd connection rib part (10), the stem of the turf (20) vegetated in each compartment (11) The roots and the like can extend not only on the upper side of the second connecting rib portion (10) but also in the lateral direction toward the adjacent compartment (11) through the second communication hole (14). Thereby, there exists an advantage that lawn (20) becomes still easier to propagate.

  In the present invention, although not shown, a recess (not shown) is provided in the second communication rib at a position below each second connecting rib portion (10) on the lower surface of each streak portion (3) of the substrate portion (2). You may be provided in the state connected with the hole (14). In this case, the root of the turf (20) vegetated in the compartment (11) can extend downward through the second communication hole (14) and the recess. This makes it easier for the turf (20) to propagate. Moreover, the water sprayed on the turf (20) can be discharged downward from the opening of the recess through the second communication hole (14) and the recess. Thereby, it is possible to further improve drainage.

  Although several embodiments of the present invention have been described above, the present invention is not limited to those shown in the above-described embodiments, and various modifications can be made.

  For example, in this embodiment, the protective plate (1) is used to protect dwarf plants such as turf (20) as a ground cover plant, but the present invention is not limited to this. Instead, it may be used for protecting ground cover plants other than grass.

  Moreover, in this embodiment, although the board | substrate part (2) of a protection board (1) is a grid | lattice form, in this invention, it is not limited to a board | substrate part (2) being a grid | lattice form. For example, a triangular lattice shape or a honeycomb shape may be used.
