The present invention has been made in view of the above problems, and the problem to be solved is a vegetation in which a convex portion of a vegetation floor plate is not damaged by a wheel load of an automobile in a structure in which the vegetation floor plate is laid. It is to provide a reinforcement structure of the use decking.

In order to achieve the above object, the reinforcing structure of a vegetation slab according to the present invention is formed on a vegetation slab having a large number of protrusions and a plurality of openings having the same height. A vegetation slab reinforcing structure provided with a load dispersion reinforcing material having a connecting portion for connecting a portion and dispersing a load applied to the convex portion to surrounding convex portions and having an opening capable of growing the plant. The load distribution reinforcing material is a welded wire mesh having a mesh in which a metal wire and a metal wire are welded and connected at the intersection, or a net having a mesh entangled with a bent portion of a bent metal wire, The mesh of the net is used as an opening for growing plants, and the top of the convex portion of the vegetation floor plate is connected to the top of the convex portion by fitting the mesh into the convex portion of the vegetation floor plate. Is.

In the reinforcement structure of the vegetation floor board of the present invention, it is preferable to provide a load dispersion reinforcing material in a range of 0 to 50% of the height of the convex part downward from the top of the convex part of the vegetation floor board. And it is preferable that the ratio of the opening of the load distribution reinforcing material to the entire area including the opening of the vegetation flooring is 10% or more and less than 100%, in particular, the diameter of the metal wire of the load distribution reinforcing material , It is preferable that it is 2.0 mm-4.0 mm. The load dispersion reinforcing material having the above-described reinforcing structure may exist on the ground surface, but it is desirable to provide it so as to exist in the ground.

The reinforcing structure of the vegetation slab according to the present invention is that the vegetation slab itself has high strength, and on the vegetation slat, a load distribution reinforcing material for connecting the convex part and the convex part is provided. Even if a load more than expected is applied to one convex portion, the load is distributed to the peripheral convex portions connected to the convex portion, and there is no fear that the convex portion of the vegetation slab is damaged. In addition , the load distribution reinforcing material is excellent in strength because it is a welded wire mesh having a mesh in which a metal wire and a metal wire are welded and connected, or a net having a mesh entangled with a bent portion of a bent metal wire, The load distribution reinforcing material can be provided on the vegetation floor plate by a simple construction in which a metal wire and a mesh formed by the metal wire are fitted into the convex portion of the vegetation floor plate. Moreover, since the load distribution reinforcing material has an opening through which the plant can grow, the plant grows smoothly without hindering the greening of the place where the vegetation flooring is laid.

  In addition, the vegetation slab reinforcing structure provided with the load distribution reinforcing material in the range of 0 to 50% of the height of the convex portion downward from the top of the convex portion of the vegetation bottom plate is downward from the top of the convex portion. By providing a load dispersion reinforcing material within the range of 0 to 50% of the height of the convex portion, the load applied to one convex portion can be efficiently dispersed to the surrounding convex portions. There is no risk of damage to the projections. On the contrary, if it is provided below the position of 50% of the height of the convex part downward from the apex of the convex part, the protruding part of the convex part will increase too much from the load dispersion reinforcing material. Since the portion may be deformed, it is preferable that the load distribution reinforcing material is provided in the range of the position of 50% of the height of the convex portion downward from the apex of the convex portion.

  Furthermore, in the reinforcing structure of the vegetation floor board in which the ratio of the opening of the load distribution reinforcing material to the entire area including the opening of the vegetation floor board is 10% or more and less than 100%, the ratio of the opening is less than 10%. Then, since the root of the plant is prevented from growing, there is a disadvantage that the growth is delayed or the plant tends to die. Therefore, the opening ratio is preferably 10% or more and less than 100%.

Also, a 2.0mm smaller than the diameter of the metallic wire, the cause of strength to missing distortion or deformation, uniform welding of metallic wire gold genus line becomes difficult. Also, becomes strong and the strength also is larger in diameter than 4.0 mm, since Weight is improved production cost increases, the diameter of the metallic wire, for vegetation is 2.0mm~4.0mm decking The reinforcing structure is preferable.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view of a reinforcing structure for a vegetation floorboard according to an embodiment of the present invention, FIG. 2 is a partially enlarged perspective view of a load distribution reinforcing material that is a component of the reinforcing structure, and FIG. 3 is a configuration of the reinforcing structure. FIG. 4 is a front view of the reinforcing structure, and FIG. 5 is a front view showing another embodiment of the reinforcing structure.

  The reinforcement structure of the vegetation floor board of the present invention shown in FIG. 1 is constructed by planting grass on the ground of parks, outdoor campgrounds, open spaces, parking lots, asphalt pavement surfaces, concrete pavement surfaces, etc. Protects the vegetation floor board 1 used for greening the parking lot from the wheel load of the car. The vegetation floor board 1 is laid on the ground or paved surface to plant the plant, and the load protects the vegetation floor board 1. It consists of a dispersion reinforcing material 2.

  The vegetation slab 1 is a substantially square slab that is injection-molded with a thermoplastic synthetic resin such as polyethylene. As shown in FIGS. Are arranged at equal intervals in the vertical and horizontal directions, and the lower ends of the convex portions 1a are connected and integrated in the vertical and horizontal directions by the connecting portions 1b. A plurality of vertical ribs 1e (a total of eight positions in the front and rear, right and left, and diagonal directions) are formed around each convex portion 1a. The vertical ribs 1e are formed on the convex portions 1a facing each other. And integrated. Thereby, each convex part 1a is reinforced so that it can bear the wheel load of a car. Furthermore, the lower end portions of the convex portions 1a located on the diagonal lines at the four corners of the vegetation floor plate 1 are connected and integrated in the diagonal direction by the diagonally connecting portions 1c, thereby increasing the strength of the vegetation floor plate 1. It is even higher. Moreover, the bottom part of this vegetation floor board 1 has many opening parts 1d enclosed by the connection part 1b of the vertical and horizontal direction, and these opening parts 1d are useful for drainage and ventilation | gas_flowing.

  If the height of the convex portion 1a of the vegetation floor board 1 (in other words, the total thickness of the vegetation floor board 1) becomes too high, when the vegetation floor board 1 is laid on the pavement, the location and laying The level difference in the area that is not done becomes large, making it difficult for the car to enter smoothly. On the other hand, if it becomes too low, the amount of land filled in the hollow 1h of the vegetation flooring 1 will be reduced too much. Therefore, the height of the convex portion 1a is preferably set to about 5 to 10 cm, and particularly preferably set to about 7 cm. The length of one side of the vegetation floor board 1 is not particularly limited, but it is preferable to set the length of one side to about 50 cm in consideration of ease of carrying.

  On the four sides of the vegetation flooring board 1, there are formed a protuberant protrusion 1f and a tapered recess 1g. As shown in FIG. 1, the vegetation flooring board 1 is arranged vertically and horizontally so that the protrusions 1f are adjacent to each other. The vegetation slats 1 and 1 can be joined to each other in a non-separable manner simply by fitting them into the recess 1g of the vegetation slat 1 to be performed.

As is apparent from the above, the vegetation floor board 1 is very strong, and since the soil is filled in the concave hollow portion 1h, there is no fear that the convex portion 1a is damaged in normal use. However, heavy vehicles such as buses and trucks and large-capacity four-wheel drive vehicles enter and exit the place where the vegetation flooring plate 1 is laid, or on the convex portion 1a of the vegetation flooring plate 1. When the steering wheel is operated while the car tire is on, or a fire truck or a crane truck is operated using a fall prevention device, the load exceeding the expected (about 1560 kN / m ² ) is one convex. If it is applied to the portion 1a, the convex portion 1a of the vegetation floor board 1 may be deformed or damaged. Therefore, the vegetation floor board 1 is further reinforced by a load dispersion reinforcing material 2 described below.

  That is, as shown in FIGS. 1 and 2, the load distribution reinforcing material 2 is a square metal welded wire mesh in which a vertical metal wire 2a and a horizontal metal wire 2b are welded and connected at their intersections. The corner portion formed by the line 2a and the horizontal metal line 2b is an opening for growing the plant. The ratio of the opening needs to be 10% or more and less than 100% of the vegetation floor board 1. If the ratio of the opening is less than 10%, the growth of the plant is delayed or withered to prevent the root of the plant from stretching. Since inconveniences such as being easy to occur occur, it is preferable to set the aperture ratio to 10% or more and less than 100%.

Moreover, as shown in FIG. 1, the said corner (opening) also becomes the fitting part 2c with the convex part 1a of the flooring board 1 for vegetation. The corners serving as the fitting portions 2c are slightly larger than the tops of the convex portions 1a of the vegetation floor board 1, and the opening area is smaller than the other corners. Since the convex portion 1a of the vegetation floor board 1 has a truncated cone shape as described above, the vertical rib 1e of the convex portion 1a is located at a fixed position as shown in FIGS. 4 and 5. It is fixed without moving further downward.
If the opening area of the fitting portion 2c is too large, the load distribution reinforcing material 2 is positioned considerably below the apex of the convex portion 1a when fitted into the convex portion 1a of the vegetation floor board 1 (see FIG. 5). Further below the position of the load distribution reinforcing material 2 shown), the protruding portion of the convex portion 1a is excessively increased from the load distribution reinforcing material 2, and the convex portion 1a may be deformed or damaged when an unexpected load is applied. Occurs. In order to prevent these, it is necessary to provide the load dispersion reinforcing material 2 in the range of the position of 50% of the height of the convex portion downward from the apex of the convex portion of the vegetation floor board 1. That is, when the height of the convex portion 1a of the vegetation floor board 1 is 7 cm, the load dispersion reinforcing material 2 is moved downward from the top of the convex portion 1a of the vegetation floor board 1 within a range of 0 mm to 35 mm, more preferably It is necessary to provide in the range of 10 mm to 20 mm downward from the top of the convex portion 1a (specifically, between the position of the load distribution reinforcing material 2 in FIG. 4 and the position of the load distribution reinforcing material 2 in FIG. 5). Therefore, in consideration of these, one side of the fitting portion 2c needs to be 2.6 cm to 3.6 cm and the opening area needs to be 6.26 cm ^{2 to} 12.96 cm ² .

As the material of this load dispersion reinforcing material 2, metal such as ordinary iron wire, plated wire, aluminum material, stainless steel, resin such as nylon and polyester, fiber reinforced resin containing glass fiber or carbon fiber, carbon fiber, etc. Various types are conceivable, but ordinary iron wires and plated wires are particularly preferable in consideration of production cost, strength, durability, and the like. At this time, if the diameters of the vertical and horizontal metal wires 2a and 2b are smaller than 2.0 mm, the strength is insufficient, causing distortion and deformation, and the vertical and horizontal metal wires 2a and 2b are uniform. Welding becomes difficult. Further, if the diameter is larger than 4.0 mm, the strength is increased, but the weight of the welded wire mesh 2 is increased and the production cost is improved, so the diameters of the vertical and horizontal metal wires 2a and 2b are 2.0 mm. It is preferable to set in a range of ˜4.0 mm, particularly 2.6 mm to 3.2 mm. The diameter may be less than 2.0 mm as long as the material can sufficiently obtain the strength as the load dispersion reinforcing material 2. In this case, when a load more than expected is applied, the load dispersion reinforcing material 2 bites into the convex portion 1a of the vegetation floor board 1, and the vegetation floor board may be deformed or damaged. In order to prevent this, a deformation preventing member can be used in a portion where the load dispersion reinforcing material 2 is in contact with the vegetation floorboard.
Moreover, although the dimension of one side of the load distribution reinforcing material 2 is not particularly limited, in the present embodiment, it is assumed that the four vegetation floorboards 1 are reinforced with the load distribution reinforcing material 2, so that If one side of the base plate 1 is 50 cm, the length of one side of the vertical metal wire 2a and the horizontal metal wire 2b of the load distribution reinforcing material 2 is 1 m.

  When the fitting portion 2c of the load distribution reinforcing material 2 having the above-described configuration is fitted into the top of the convex portion 1a of the vegetation floor board 1, the convex portions 1a are connected to each other. Thus, if the convex parts 1a are connected with the load distribution reinforcing material 2, the load applied to one convex part 1a passes through the load distribution reinforcing material 2 to the surrounding convex parts 1a (four places on the front, rear, left and right). Distributed. And since the load disperse | distributed to the surrounding convex part 1a will be further disperse | distributed to the surrounding convex part 1a, it is in buffering a load with all the convex parts 1a provided in the floor board 1 for vegetation. Become. Therefore, even if a considerably strong external force is applied to one convex portion 1a, there is no fear that the convex portion 1a is damaged due to the high strength of the vegetation base plate 1 itself.

  The load distribution reinforcing material 2 is not limited to the square welded wire mesh, and may be a diamond welded wire mesh 20 having a rhombus opening 20c shown in FIG. Further, a welded wire mesh 21 having a honeycomb structure having a hexagonal opening 21c as shown in FIG. 7 may be used, and a welded wire mesh 22 having a triangular fitting portion 22c (opening) and a pentagonal opening as shown in FIG. But you can. Further, instead of a welded wire mesh, a rhombus net 23 entangled with a bent portion of a metal wire bent in a zigzag shape as shown in FIG. 9 may be used.

  On the other hand, a load distribution reinforcing material 24 as shown in FIG. 10 may be used instead of the wire mesh type load distribution reinforcing material as described above. The load distribution reinforcing material 24 shown in FIG. 10 is obtained by connecting ring portions 24a and 24a to be fitted into the convex portion 1a of the vegetation floor board 1 by a connecting portion 24b, and one ring portion 24a is connected to the convex portion of the vegetation floor board 1. The ring part 24a on the opposite side is fitted into the convex part 1a adjacent to the vertical part or the horizontal side of the convex part 1a and the convex parts 1a are connected by repeating these operations. Reinforce 1

Further, a load distribution reinforcing material 25 as shown in FIG. 11 may be used in place of the wire mesh type load distribution reinforcing material as described above. This load dispersion reinforcing material 25 is a plate-like body having a hole 25a (fitting part) to be fitted into the convex part 1a of the vegetation floor board 1 and a vegetation hole 25b (opening) in which a plant can grow. When the fitting portion 25a of the dispersion reinforcing material 25 is fitted into the top of the convex portion 1a of the vegetation floor plate 1, the convex portions 1a of the vegetation floor plate 1 are connected to each other. Therefore, even when this load distribution reinforcing material 25 is used, the same effect as when the load distribution material 2 described above is used can be obtained.
The material for the load dispersion reinforcing material 25 may be a resin such as polyolefin or polycarbonate, or a fiber reinforced resin containing glass fiber or carbon fiber in addition to metal.

  In this way, the load distribution reinforcing material has an opening that allows plants to grow, can connect the convex portions 1a of the vegetation flooring board 1, and can distribute the load applied to the convex portions 1a to the surrounding convex portions 1a. Anything can be used.

  Using the members configured as described above, a green parking lot is formed in the following manner.

First, as shown in FIG. 1, the vegetation laying boards 1 are arranged vertically and horizontally on the pavement surface, and the protruding portions 1f are fitted into the recessed portions 1g and laid while being joined. At this time, it is desirable to arrange simple irrigation equipment. Providing irrigation equipment has the advantage that good vegetation can be maintained by omitting troublesome watering operations during high-temperature periods such as summer and dry periods. In that case, if a irrigation facility is provided with a timer or the like and automatic irrigation is performed, it is possible to prevent excessive irrigation and save water.
In some cases, a planar drainage material in which a nonwoven fabric or an uneven resin plate is coated with a water-permeable nonwoven fabric may be laid on the pavement surface, and the vegetation flooring plate 1 may be laid on the pavement surface.

  Next, the guest soil is charged and filled into the hollow portion 1h of the vegetation floor board 1. As the soil to be filled in the concave space 1h, peat-improved lightweight soil excellent in water retention, fertilizer, ion exchange capacity, drainage, breathability and the like is preferably used. Then, after placing turf seedlings, etc. on these soils, and rolling and planting a greening plant while sprinkling water, the above-mentioned fitting portion 2c of the load distribution reinforcing material 2 is used as the convex portion of the vegetation floor plate 1 The greening parking lot which is fitted in 1a and has excellent wheel load resistance is completed.

  As is clear from the above description, the reinforcing structure of the vegetation floor board 1 according to the present invention is not only the vegetation floor board 1 itself is strong, but also the convex portion of the vegetation floor board 1 by the load distribution reinforcing material 2. By connecting 1a and the convex part 1a, the load applied to one convex part 1a is distributed to the surrounding convex part 1a, so that a heavy vehicle such as a four-wheel drive vehicle with a large displacement can be used in a parking lot. Going in and out, operating the steering wheel while the car tires are on the convex part 1a of the vegetation flooring 1, or working with a fire-fighting car, a crane car, etc. using the fall prevention device, etc. Even if the load is applied to one convex portion 1a, there is no fear that the convex portion 1a of the vegetation flooring 1 will be damaged. And since the load distribution reinforcement material 2 has the opening which can grow a plant, a plant grows smoothly, without preventing greening of a parking lot. In addition, the greening parking lot formed with such a member does not need to excavate the existing pavement surface using heavy machinery or the like as in the prior art, so it can be constructed easily and inexpensively, Since the dumping process is unnecessary, it is preferable from the viewpoint of environmental protection. Furthermore, since the height of the convex portion 1a of the vegetation slat 1 (the total thickness of the vegetation slab) is small, the filling amount of the soil filled in the concave portion 1h of the vegetation slat 1 can be reduced. There are many excellent effects such as being able to construct on the concrete pavement of the roof of a multistory parking lot without worrying about sacrificing safety.
