  The present invention has been made in view of the above problems, and the problem to be solved is to protect plants such as lawns from wheelchairs, bicycles, pedestrians, etc., in welfare facilities, public facilities, hospitals, nursing homes, etc. The object is to provide a barrier-free plant protection structure suitable for installation.

  In order to achieve the above object, the plant protection structure according to the present invention has a vertical metal line and a horizontal metal line at the intersection point on a vegetation floor having a large number of convex portions and a large number of openings having the same height. Is a plant protection structure in which a welded wire mesh having corners welded in place is placed and the upper part of the convex part of the vegetation slat is fitted into the corner of the welded wire mesh, and the welded wire mesh is used for the vegetation At least a vertical and horizontal metal line that is not in contact with the convex part of the vegetation slab is between the vertical and horizontal metal line that is in contact with the upper part of the convex part of the slab and the vertical and horizontal metal line that is in contact with the upper part of the convex part adjacent to the convex part. One or more are provided.

  In the plant protection structure according to the present invention, the diameter of the vertical and horizontal metal wires is 2.0 mm to 4.0 mm, and the vertical and horizontal metal wires are in contact with the upper portions of the convex portions of the vegetation floor plate and the convex portions of the vegetation floor plate. It is preferable that the space | interval with the vertical and horizontal metal wire which is not performed is 5.0 mm-50 mm. Moreover, the plant protection structure which mounted the welded wire mesh in the range of the position of 0-10 mm below the vertex of the convex part of the vegetation floor board is more preferable.

  The plant protection structure of the present invention is a vertical and horizontal not contacting the projection between the vertical and horizontal metal wires in contact with the top of the convex portion of the vegetation floor board and the vertical and horizontal metal wires in contact with the top of the convex portion adjacent to the convex portion. Because it uses a welded wire mesh with at least one metal wire, the opening area of the corners formed by the vertical and horizontal metal wires is small, so that pedestrians can ride and wheelchairs and bicycle wheels are fitted There will be no hindrance. Moreover, since the wheel does not fit, the plant is protected from the wheel and the shoe sole, and is particularly suitable for installation in welfare facilities, public facilities, hospitals, nursing homes and the like. In addition, when the welded wire mesh is placed on the vegetation floorboard, the convex portions are connected to each other by the welded wire mesh, so the load applied to one convex portion is distributed to all the convex portions and an unexpected load is applied. However, it is possible to prevent the convex portion of the vegetation floor board from being deformed.

  Since the width of a tire of a normal bicycle or wheelchair is about 1.0 inch to 2.5 inch, the diameter of the vertical and horizontal metal wires is 2.0 mm to 4.0 mm, and is in contact with the upper part of the convex part of the vegetation floor board. The vertical and horizontal metal wires and the vertical and horizontal metal wires that do not touch the convex portions of the vegetation floor board are in contact with the upper portions of the convex parts of the vegetation floor board, as in the plant protection structure with 5.0 mm to 50 mm. If the distance between the metal wire and the vertical and horizontal metal wires that do not contact the convex part of the vegetation flooring plate is as described above, the tires of bicycles and wheelchairs fit into the corners formed by the vertical and horizontal metal wires. It wo n’t be hindered, and it wo n’t interfere with travel or damage plants. If the diameter of the vertical and horizontal metal wires is smaller than 2.0 mm, it becomes difficult to uniformly weld the vertical metal wires and the horizontal metal wires, and if heavy objects such as automobiles act on the welded wire mesh, It becomes insufficient and causes distortion and deformation. If it is 2.0 mm or more, it can sufficiently withstand the load caused by temporary parking of emergency vehicles such as fire engines and ambulances and large vehicles such as buses. Conversely, if the diameter is larger than 4.0 mm, the strength becomes stronger, but the weight of the welded wire mesh is increased and the production cost is improved, so the diameter of the vertical and horizontal metal wires is 2.0 mm to 4.0 mm. Certain plant protection structures are preferred.

  If the welded wire mesh is placed below 10 mm downward from the top of the convex portion of the vegetation floor plate, the protruding portion of the convex portion becomes excessive, and a step is generated between the vegetation floor plate and the welded wire mesh. It will also be a cause. In order to prevent these, a plant protection structure in which a welded wire mesh is placed in a range of 0 to 10 mm downward from the top of the convex portion of the vegetation flooring plate is preferable.

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

  FIG. 1 is a partial plan view showing a plant protection structure according to an embodiment of the present invention, FIG. 2 is a plan view of a vegetation floor board that is a component of the protection structure, and FIG. 3 is a weld that is a component of the protection structure FIG. 4 is a front view of the protective structure, FIG. 5 is a partial plan view for explaining a method of connecting the vegetation slats that are constituent members of the protective structure, and FIG. 6 is a constituent member of the protective structure. It is a fragmentary sectional view which shows the state which mounted the welded wire mesh on a certain vegetation board.

  Since the plant protection structure of the present invention shown in FIG. 1 protects plants such as lawns from wheelchairs, bicycles, pedestrians, etc., and does not hinder their running or walking, in particular, welfare facilities, public facilities, hospitals, The vegetation floor plate 1 shown in FIG. 2 and the welded wire mesh 2 shown in FIG. 3 placed on the vegetation floor plate 1 are suitable for installation in a nursing home.

  The vegetation laying board 1 is a substantially square laying board injection-molded with a thermoplastic synthetic resin such as polyethylene, and as shown in FIGS. 2 and 4, a large number of frustoconical convex portions 1 a having a frustoconical shape having the same height. 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 are reinforced so that each convex portion 1a can withstand the load.

  Furthermore, as shown in FIG. 2, the lower end portions of the convex portions 1a located on the diagonal lines of the four corners of the vegetation floor board 1 are connected and integrated in the diagonal direction by diagonally connecting portions 1c. The strength of the floorboard 1 is further increased so that it will not be damaged even if an automobile or the like enters. 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.

  On the four sides of the vegetation slat 1 are formed a projecting portion 1f that widens forward and a concave portion 1g that is tapered. As shown in FIGS. 1 and 5, the vegetation slats 1 are arranged vertically and horizontally to form a projecting portion. The vegetation slats 1 and 1 can be joined to each other in a non-separable manner simply by fitting the 1f into the recess 1g of the adjacent vegetation slat 1.

  Since the vegetation floor board 1 of the present invention is laid in welfare facilities, public facilities, hospitals, nursing homes, etc., when the vegetation floor board 1 is laid, in order to prevent accidental fall, It is preferable that the level difference from the ground (in other words, a place where the vegetation flooring 1 is not laid) is as small as possible. Therefore, at the time of construction, the ground is often excavated in advance so that the top of the convex portion 1a of the vegetation floor board 1 does not protrude too much from the ground. Therefore, if the height H of the convex portion 1a of the vegetation floor board 1 (in other words, the total thickness of the vegetation floor board 1) is too high, the excavation work becomes large and construction costs increase, which is not preferable. On the other hand, if it is too low, the amount of soil filled in the hollow portion 1h of the vegetation flooring 1 will be reduced too much and the growth state of the greening plant will be deteriorated. Therefore, the height H of the convex portion 1a is 5 It is preferable to set to about 10 cm, and in this embodiment, it is set to 7 cm. The length of one side of the vegetation floor board 1 is not particularly limited, but the length of one side is set to 50 cm in consideration of the space to be laid and ease of carrying.

  On the other hand, as shown in FIG. 1 and FIG. 3, the welded wire mesh 2 placed on the above-described vegetation floor plate 1 includes vertical and horizontal metal wires 2 a and 2 b that are in contact with the top of the convex portion 1 a of the vegetation floor plate 1. The vertical and horizontal metal wires 2a, 20a, 2b, and 20b are connected by being welded at their intersections in a square metal welded wire mesh made of vertical and horizontal metal wires 20a and 20b that do not contact the convex portion 1a.

The corner portion formed by the vertical metal wire 2a and the horizontal metal wire 2b in contact with the upper portion of the convex portion 1a of the vegetation floor plate 1 is the fitting portion 2c with the convex portion 1a of the vegetation floor plate 1 described above. It becomes. The corners serving as the fitting portions 2c are the same as or slightly larger than the tops of the convex portions 1a of the vegetation floor board 1. Furthermore, it is preferable that the opening area of the corner serving as the fitting portion 2c is larger than that of the other corner. Since the convex part 1a of the vegetation flooring board 1 has a truncated cone shape as described above, the fitting part 2c is caught by the vertical rib 1e of the convex part 1a at a fixed position as shown in FIG. , It is fixed without moving downward.
If the opening area of the fitting portion 2c is too large, the welded wire mesh 2 is positioned considerably below the top of the raised portion 1a and is protruded from the welded wire mesh 2 when fitted into the raised portion 1a of the vegetation base plate 1. Since the protruding part of the part 1a increases too much, it causes a fall accident and is dangerous. In addition, if a heavy load for construction such as a crane truck gets in, an excessive load is assumed, and the convex portion 1a may be deformed or damaged. In order to prevent these, it is preferable to suppress the step L from the apex of the convex portion 1a of the vegetation base plate 1 to the welded wire mesh 2 to 10 mm or less. It is placed in a range of 0 to 10 mm downward from the apex. Considering this, one side of the fitting portion 2c is formed to be ² cm to ³ cm, and the opening area is 4 cm ^{2 to} 9 cm ² .

  Vertical and horizontal metal wires 20a and 20b that do not contact the convex portion 1a of the vegetation floor board 1 are vertically and horizontally connected to the upper portion of the convex portion 1a and the upper portion of the convex portion 1a adjacent to the convex portion 1a. The three vertical and horizontal metal wires 2a and 2b are in contact with each other. By providing the vertical and horizontal metal wires 20a and 20b, a wheelchair, a bicycle, a pedestrian, etc. Even if you travel or walk on the vegetation, the lawn and other plants planted on the vegetation flooring 1 are protected from wheelchairs, bicycle wheels and soles, and the wheels and soles do not fit into the openings. Do not disturb their running and walking. Therefore, it is not preferable that the opening space becomes too large, and the width of a tire such as a wheelchair or a bicycle is usually about 1.0 inch to 2.5 inch, so that it does not fit in the opening space. The vertical and horizontal metal wires 20a and 20b not in contact with the portion 1a are provided at intervals of 12 mm.

  The corners formed by the vertical and horizontal metal wires 20a, 20b not in contact with the convex portion 1a of the vegetation floor board 1 also serve as openings for growing plants. 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 the problem of being easy to occur occurs, the ratio of the opening is set to 10% or more and less than 100%.

  As shown in FIGS. 3 and 4, the vertical and horizontal metal wires 2a and 2b in contact with the upper portion of the convex portion 1a of the welded wire mesh 2 and the vertical and horizontal metal wires 20a and 20b not in contact with the convex portion 1a Both ends are folded inward to prevent injury.

As the material of the welded wire mesh 2 having the above-described configuration, ordinary iron wire, plated wire, aluminum material, stainless steel, and other metals are conceivable, but ordinary iron wire and plated wire are particularly preferable in consideration of production cost, strength, durability, and the like. preferable. At this time, if the diameters of the vertical and horizontal metal wires 2a, 20a, 2b, and 20b are smaller than 2.0 mm, the strength is insufficient, causing distortion and deformation, and the vertical metal wires 2a, 20a and the horizontal It becomes difficult to uniformly weld the metal wires 2b and 20b. 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, 20a, 2b, 20b are 2 It is preferable to set within a range of 0.0 mm to 4.0 mm, particularly 2.6 mm to 3.2 mm.
The diameter may be less than 2.0 mm as long as the strength of the welded wire mesh 2 can be sufficiently obtained. In this case, the welded wire mesh 2 is projected to the convex portion 1a of the vegetation base plate 1 when a load more than expected is applied. The vegetation floor board 1 may be deformed or damaged by biting into the vegetation. In order to prevent this, a deformation preventing member can be used in a portion where the welded wire mesh 2 is in contact with the vegetation floor plate 1.

  Moreover, although the dimension of one side of the welded wire mesh 2 is not particularly limited, in the present embodiment, it is assumed that the welded wire mesh 2 is placed on the four vegetation floor plates 1, 1, 1, 1. Therefore, if one side of the vegetation floor plate 1 is 50 cm, the length of one side of the vertical metal wires 2a and 20a and the horizontal metal wires 2b and 20b of the welded wire mesh 2 is 1 m.

  When the welded wire mesh 2 having the above-described configuration is placed on the above-described vegetation base plate 1, the vertical and horizontal metal wires 2a and 2b that are in contact with the top of the convex portion 1a of the vegetation base plate 1 and the convexes adjacent to the vertical and horizontal metal wires 2a and 2b Since three vertical and horizontal metal wires 20a and 20b that do not contact the convex portion 1a are provided between the vertical and horizontal metal wires 2a and 2b that are in contact with the portion 1a, the wheel of a wheelchair, a bicycle, etc. It does not fit into the empty space 1h and does not hinder traffic. Moreover, since each convex part 1a of the flooring board 1 for vegetation will be connected, the load concerning one convex part 1a will pass through the welded metal mesh 2, and the surrounding convex part 1a (front, back, left, right 4) Since the load distributed to the surrounding convex portions 1a is further distributed to the surrounding convex portions 1a, the load is applied to all the convex portions 1a provided on the vegetation flooring 1. Will be buffered. Therefore, even if a car or the like enters, there is no fear that the convex portion 1a of the vegetation floor board 1 is damaged.

  Next, one construction example of the plant protection structure using the above-described vegetation floor board 1 and the welded wire net 2 will be described.

As shown in FIG. 1 and FIG. 5A, vegetation floor boards 1 are arranged vertically and horizontally in places where vegetation such as welfare facilities, public facilities, hospitals, nursing homes and the like is to be vegetated, as shown in FIG. 5B. The projecting portion 1f of the vegetation floor plate 1 is laid while being fitted into and connected to the recess 1g of the adjacent vegetation floor plate 1. At this time, when the floor plate for vegetation 1 is laid and a level difference is generated from the normal ground, it is necessary to excavate the ground in advance.
If a simple irrigation system is installed at the same time as laying the vegetation base plate 1, it is possible to maintain good vegetation by omitting troublesome watering work even in high-temperature periods such as summer and dry periods. This is preferable because of its advantages. 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.
Moreover, depending on the case, you may make it lay the vegetation floor board 1 after laying the planar drainage material which coat | covered the nonwoven fabric and the uneven resin board with the water-permeable nonwoven fabric.

  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, grass seedlings and the like are placed on these soils, and the greening plants are planted by rolling while spraying water.

  After the planting plant 1 is planted on the vegetation floor board 1, the fitting portions 2 c of the welded wire mesh 2 are fitted into the respective convex portions 1 a of the vegetation floor board 1, and as shown in FIG. The plant protection structure of the present invention is completed by bringing 2a and 2b into contact with the vertical ribs 1e of the vegetation floor board 1 and pushing them to a position where they do not move downward.

  As is apparent from the above description, the plant protection structure of the present invention is provided on the top and bottom of the convex portions 1a adjacent to the vertical and horizontal metal wires 2a and 2b that are in contact with the top of the convex portion 1a of the vegetation flooring 1. Between the vertical and horizontal metal lines 2a and 2b that are in contact with each other, three vertical and horizontal metal lines 20a and 20b that are not in contact with the convex portion 1a are provided at intervals of 12 mm, so that the corners formed by the vertical and horizontal metal lines 20a and 20b are provided. The opening area of the eyes is small, wheelchairs and bicycle wheels are fitted into the vehicle, and there is no danger of damaging the plant. In addition, even if a car or the like intrudes, the vegetation floor board 1 itself is strong and the projections 1a are connected to each other by the welded wire mesh 2, so the load applied to one projection 1a. Is distributed over the entire convex portion 1a, and the convex portion 1a is not likely to be deformed or damaged, and is particularly preferably installed in welfare facilities, public facilities, hospitals, nursing homes and the like.
