DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on specific embodiments, but the present invention is not limited to such embodiments.
[0028]
As shown in FIG. 1, the planting mat 1 of the present invention comprises a synthetic resin mat frame 2 in which a plurality of substantially square cells 6 having openings 7 formed in the bottom are recessed so that the tops are open. And a lightweight growth material 8 packed in the cell 6 and having at least a surface treated with a binder.
[0029]
As shown in FIG. 2, the mat frame 2 is divided into a rectangular frame 3 composed of an outer peripheral wall 3a and a bottom surface 3b by integrally molding a vertical side wall 5 for cell formation having a height equal to or lower than the outer peripheral wall 3a vertically and horizontally. Each of the substantially square cells 6 is recessed. Therefore, the adjacent cells 6 are connected to each other by the cell forming vertical side walls 5. In this example, the cell-forming vertical side wall 5 is integrally formed with the rectangular frame 3, but the two are not integrally formed, but the rectangular frame 3 composed of the outer peripheral wall 3a and the bottom surface 3b is formed in a lattice shape as a separate member. The cell forming vertical side walls 5 may be housed and arranged.
[0030]
In the cell 6 adjacent to the outer peripheral wall 3a, an opening 7 is bored from the side of the bottom surface 3b to the lower portion of the outer peripheral wall 3a, and an appropriate size is provided on the inner portion of the cell bottom surface 6b of the cell 6. An opening 7 (not shown) having a shape and a number is formed. Further, the cell bottom surface 6b of the cell 6 located inside the cell 6 is similarly provided with openings 7 (not shown) having an appropriate size, shape and number.
[0031]
However, as described above, the size of the opening 7 is appropriate, but at least the size of the opening 7 is compatible with irrigation of the planting mat 1. That is, the size is suitable for draining surplus water when irrigating the planting mat 1 with a watering can.
[0032]
Further, in the mat frame 2, as shown in FIG. 3, the cells 6 may be connected to each other by the connecting ribs 9 at the upper end portions of the cell side walls 6 a of the plurality of recessed substantially square cells 6. A peripheral rib 4 having a height equal to or higher than the height of the connecting rib 9 is provided at the upper end portion of the cell side wall 6 a in the outer peripheral portion of the mat frame 2. In the vicinity of the center of each side of each cell bottom surface 6b, four openings 7 are provided from the side of the cell bottom surface 6b to the lower part of the cell side wall 6a (see FIG. 4). In such a mat frame 2, each cell 6 is independent only by being connected by a connecting rib 9 at the upper end, and compared with the mat frame 2 that partitions the inside of the rectangular frame 3 by the cell forming vertical side walls 5, It has the flexibility to follow more unevenness (slab) on the laying surface. Therefore, it is preferable that the peripheral rib 4 and the connecting rib 9 have a thickness that exhibits flexibility.
[0033]
Note that the shape of the mat frame 2 is not limited to the above example, and any shape may be used as long as the mat frame 2 has a plurality of cells 6 that are recessed so as to open at the top. Further, the shape of the cell 6 is not limited to a substantially square shape. As will be described later, the mat frame 2 has various modifications.
[0034]
The mat frame 2 is preferably made of synthetic resin, and vinyl chloride, polypropylene, polyester, polyethylene, polystyrene, etc. are used. The mat frame 2 is molded by vacuum molding, blow molding, injection molding, extrusion molding, or the like. Formed with.
[0035]
The thickness of the mat frame 2 has a certain degree of flexibility, and follows the unevenness of the laying surface (slab), etc., and at the same time, the mat frame 2 does not collapse even if a person gets on the mat frame 2 directly or with a walking board. It is necessary to have a certain degree of strength. For example, a thickness of 0.4 to 2.0 mm is preferable. The size of the mat frame 2 is appropriate, and in the present embodiment, it is about 500 × 500 × 100 mm.
[0036]
The light growth material 8 (artificial light soil) which is a plant growth material laid in the cell 3 is a plant culture medium. For example, pumice is packed on the lower side by about 1/3 to 2/3, and the upper part thereof. In addition to perlite, vermiculite, peat moss, bark compost, chafcon, wood decay organic matter, etc., silicate white clay for preventing root rot, which is considered necessary, is selected appropriately according to the type of planting, environment, etc. In order to improve drainage, it is well-balanced. By adopting such a lightweight growth material 8 with good air permeability, it is possible to prevent plant roots from being damaged. The load due to these lightweight growth materials 8 is about 1/3 of the conventional soil, and the load on the laying surface can be reduced.
[0037]
As another example of the lightweight growth material 8, the culture soil is put together with a binder such as starch paste into a mold of a required shape, pressed by a press machine so that the thickness is about half, and then passed through hot air to be cured. Some are also available.
[0038]
When the light growth material 8 is spread in the cell 6, the light growth material 8 may be directly spread, but after the filter 10 is first laid in the cell 6 as shown in FIG. If 8 is spread, it is even better. The filter 10 is laid so as to close the opening 7 in the cell 6 in order to prevent the outflow of minute components in the lightweight growth material 8. A non-woven fabric, net, tulle or the like is used for the filter 10.
[0039]
When binder treatment is performed on at least the surface of the lightweight growth material 8, first, an alginic acid solution, a starch solution, or the like is sprayed, and after spraying the binder powder, water such as hot water is sprayed on the sprayed surface, or a binder sheet is mounted. It is carried out by means such as placing and spraying water such as warm water on the upper surface of the sheet. In the case of a binder powder or a binder sheet, water such as warm water is supplied and dispersed, so that the planting mat 1 is prevented from becoming dirty and is easily mass-produced in production. After the spraying or supply spraying, the surface of the light weight growing material 8 is dried. As a means for drying, either natural drying or forced drying may be used.
[0040]
The above-mentioned binder treatment means is appropriately selected in consideration of the growing conditions of the plant and the nature and characteristics of the mixture of the lightweight growing material 8. Since at least the surface of the light weight growing material 8 is fixed by the binder treatment, scattering and movement of the light weight growing material 8 that is soil can be prevented, and handling becomes extremely easy.
[0041]
Furthermore, on the upper surface of the light-weight growing material 8 subjected to the binder treatment, seeding, fixing of the seed sheet 23, and planting of the ground cover plant are performed at the production site of the planting mat 1 or the installation site of the planting mat 1. Is called. In addition, when the seed or seed sheet 23 is placed or fixed on the surface of the light growth material 8, it is preferable to spray the binder solution again on the upper surface so that the seed or seed sheet 23 does not fly due to wind or the like. In some cases, sowing or placing and fixing the seed sheet 23 may be performed first, and then the binder solution may be sprayed and dried.
[0042]
The solution used for the binder treatment described above gradually flows out in the process of irrigation to grow plants, but at the same time the soil gradually stabilizes due to irrigation, etc., so the soil decreases after the binder solution etc. flows out. Can be prevented. Further, since the binder solution or the like flows out, it does not affect the growth of the plant.
[0043]
Next, the case where the reinforcement member 11 is provided in the cell 6 of the planting mat 1 will be described. As shown in FIG. 5, a cross-sectional cross-shaped and wall-shaped reinforcing member 11 which is a separate member in the diagonal direction in the substantially square cell 6 is fitted and formed in a direction perpendicular to the cell bottom surface 6b. The reinforcing member 11 is partitioned into a plurality of defining portions 14. The shape of the reinforcing member 11 in the present embodiment is a cross-shaped cross section, but in addition to this, a suitable shape such as a lattice or a plurality of columns standing upright from the bottom surface 6b in each cell 6 is appropriate. The height of the reinforcing member 11 is substantially the same as the height of the connecting rib 9 that connects the cells 6, but is not limited to this, and as long as the height does not exceed the upper end of the cell side wall 6 a. Good.
[0044]
When the portion of the cell 6 fitted with the reinforcing member 11 is enlarged (FIG. 6), a thick portion 12 is formed on the central portion of the reinforcing member 11 and the upper portion of the four end portions, and a small hole 13 is formed on the top surface. It has been drilled. The small hole 13 plays a role of fixing the seed sheet 23 or the cut grass when using a seed sheet 23 or the cut grass described later. A raised portion 15 is formed from the lower part of the cell side wall 6a of the cell 6 toward the center of the cell bottom surface 6b. Has been. The inner side of the raised portion 15 is an inverted U-shaped space that forms a groove-shaped opening 7, and excess water is discharged through the opening 7.
[0045]
When the cell 6 is partitioned into the defining portion 14 by the wall-shaped reinforcing member 11, the water inlet 16 and the opening 7 are provided in the vicinity of the cell bottom surface 6 b of the cell 6 for each of the defining portions 14 for passing water as in this embodiment. However, the opening 7 or the like is not provided for each of the defining portions 14, but a notch or a hole for communication between the defining portions 14 is formed in the vicinity of the lower portion of the reinforcing member 11, and the cell bottom surface 6 b is formed. Water may be passed through one opening 7 provided.
[0046]
The material and molding method of the reinforcing member 11 are not particularly limited, and the same material as the synthetic resin molded product or the mat frame 2 can be used. The thickness is appropriate as long as it has a function of reinforcing the inside of the cell 6.
[0047]
Here, a modification of the reinforcing member 11 separate from the mat frame 2 is shown. FIG. 7 shows a reinforcing member 11 that is integrally fitted up and down, and the two flat plates 17a and 17b are integrally fitted up and down by notches 18a and 18b to form the reinforcing member 11. Since the reinforcing member 11 is rotatable to some extent around the longitudinal direction of the notches 18a and 18b, it can cope with a change in the shape of the cell 6. FIG. 8 shows the reinforcing member 11 that fits into the concave and convex portions. In the central plane 19c of the two right-angle plates 19a and 19b that are substantially right angles, the convex portions 20a and the concave portions 20b are fitted into the concave and convex portions to form the reinforcing member 11. . FIG. 9 shows the reinforcing member 11 that engages the arc portion with the concave and convex portions. In the central portion of the two curved plates 21a and 21b, the arc convex portion 22a and the arc concave portion 22b are engaged with the concave and convex portions to form the reinforcing member 11. .
[0048]
Since the reinforcing member 11 is separable from these, it is easy to handle without taking up space in manufacturing, storage, management, carrying-in, etc. Further, the reinforcing member 11 in FIG. It can be folded by rotating in this direction, and has the same effect as described above to some extent without separation.
[0049]
An example of the planting mat 1 using the separate reinforcing member 11 is as shown in FIG. In this example, in the mat frame 2 in which a separate reinforcing member 11 is fitted in each cell 6 in FIG. 5, the lightweight growing material 8 is packed in each defined portion 14 partitioned by the reinforcing member 11. After the binder solution is sprayed on the surface of 8 and dried, the seed sheet 23 is placed on the upper surface of the lightweight growing material 8. And the seed sheet 23 is made into a lightweight growth material by the small hole 13 drilled in the top surface of the thick part 12 formed in the center part of the reinforcing member 11 and the upper part of the end part, and a stopper 24 such as a pin or a nail. 8 is fixed to the upper surface.
[0050]
By fixing the seed sheet 23, the seed sheet 23 comes into surface contact with the upper surface of the lightweight growth material 8, and does not float or fly, and effectively absorbs moisture and germinates. The same applies to the case where the cut grass is fixed to the mat frame 2 instead of the seed sheet 23.
[0051]
In the above example, the reinforcing member 11 is separated from the mat frame 2, but the reinforcing member 11 can be integrally formed with the mat frame 2. Hereinafter, an example in which the reinforcing member 11 is integrally formed with the mat frame 2 will be described.
[0052]
FIG. 11 shows an example in which the reinforcing member 11 is molded integrally with the mat frame 2. In the mat frame 2, a plurality of substantially square cells 6 are connected to each other via connecting ribs 9 at the upper end of the cell side wall 6a, and at the same time, a reinforcing member 11 is integrally formed in each cell 6 in a cross shape. A thick portion 12 is formed in a connecting portion between the peripheral rib 4 and the reinforcing member 11 and a connecting portion between the connecting rib 9 and the reinforcing member 11, and a small hole 13 is formed in the top surface of the thick portion 12. Yes. In this case, the lower part of the reinforcing member 11 can be formed to be short like a state where it floats from the cell bottom surface 6 b (not shown) in each cell 6.
[0053]
Furthermore, the modification in the case of integrally molding the reinforcing member 11 to the mat frame 2 is shown in FIGS. The mat frame 2 connects a plurality of substantially square cells 6 to each other via connecting ribs 9 at the upper end of the cell side wall 6a, and at the same time, the reinforcing member 11 is perpendicular to the cell bottom 6b in the cell 6 in a cross shape. The reinforcing member 11 is formed so as to be separated from the inner cell side wall 6 a of each cell 6. The height of the reinforcing member 11 is substantially the same as that of the upper end portion of the connecting rib 9, and the shape thereof is a one-flow inclined surface in which the outer periphery of the vertical wall 25 becomes lower toward the bottom surface. A small hole 13 is formed in the center of the reinforcing member 11.
[0054]
Here, the size and formation position of the vertical wall 25 of the reinforcing member 11 are appropriate, and as shown in FIG. 13B, the vertical wall 25a is integrally formed vertically and horizontally with the cell side wall 6a in the vertical direction. The size of the wall 25 may be reduced. In FIG. 13B, the positions of the openings 7 are the four corners of the cell bottom surface 6 b of each cell 6.
[0055]
As the filter 10 used in the mat frame 2 of this example, it is convenient to use a filter 10 in which a cut 26 corresponding to the shape of the reinforcing member 11 is previously formed (see FIG. 13C).
[0056]
In this example, the vertical wall 25 of the reinforcing member 11 is formed in four directions, but other three directions, five directions, etc. are appropriate. As a molding method, vacuum molding or the like is used.
[0057]
If the mat frame 2 is configured as shown in FIG. 12, it is easy to manufacture in the manufacturing process, the manufacturing cost can be reduced, and the filter 10 can be easily disposed.
[0058]
Furthermore, when the planting mat 1 is no longer needed, the reinforcing member 11 is a single-flow inclined surface when the light-grown material 8 is taken out from the mat frame 2 and separated, so that the mat frame 2 is turned over. As a result, the light weight growing material 8 inside thereof can be easily discharged, and the mat frame 2 can be easily reused. Since the mat frame 2 is made of a synthetic resin, when the mat frame 2 cannot be reused, it can be treated as a regenerated resource.
[0059]
Although the reinforcing member 11 having the one-flow inclined surface is integrally formed with the mat frame 2, the reinforcing member 11 may be formed on the mat frame 2 as a separate member. For example, an upward convex portion is provided on the cell bottom surface 6b of each cell 6 of the mat frame 2, and a concave portion is provided on the bottom of each vertical wall 25 of each reinforcing member 11, and the corresponding convex portion and concave portion are fitted into the concave and convex portions. The reinforcing member 11 can be formed in the cell 6.
[0060]
As a further modification in which the reinforcing member 11 is integrally molded with the mat frame 2, a vertical side wall for cell formation in which a plurality of openings 7 (not shown) are formed in the bottom surface 3 b of the rectangular frame 3 to form a plurality of cells 6. 5 and a cross frame-shaped reinforcing member 11 integrally molded, and a plurality of substantially square cells 6 are connected to each other via connecting ribs 9 at the upper end of the cell side wall 6a. The mat frame 2 (FIG. 15) in which the reinforcing member 11 is integrally formed is shown.
[0061]
Further, as shown in FIG. 16, the mat frame 2 is a separate definition in which the rectangular frame 3, the cell forming vertical side wall 5, and the reinforcing member 11 that partitions each cell 6 into a plurality of defining portions 14 are integrally formed. It is possible to have the same form as the mat frame 2 of FIG. 14 by arranging the defining member 27 in the rectangular frame 3.
[0062]
Further, as shown in FIG. 17, the height of the cell forming vertical side wall 5 is formed lower than the height of the upper end portion of the outer peripheral wall 3a in the rectangular frame 3 to compensate for the shortage of the height of the cell forming vertical side wall 5. An defining member 27 having additional vertical side walls 28 for cell formation may be fitted. The defining member 27 is integrally formed with a cross-shaped cross-shaped wall-shaped reinforcing member 11 and a cell-forming additional vertical side wall 28 dividing the inside of the cell 6 into a plurality of defining portions 14. A notch recess 29 is formed in the lower part of the connecting portion of the additional vertical side wall 28 so that the tip reaches the cell bottom surface 6 b inside the rectangular frame 3. The notch recess 29 is fitted so as to straddle the cell-forming vertical side wall 5, and the inside of the cell 6 is completely partitioned by the reinforcing member 11 into the defining portion 14, and finally the upper end portion of the outer peripheral wall 3 a. The height is substantially the same as the combined height of the cell forming vertical side walls 5 and the cell forming additional vertical side walls 28.
[0063]
As shown in FIG. 18, the reinforcing member 11 and the additional vertical side wall for cell formation are also used in the case of the mat frame 2 integrally formed with the connecting rib 9 between the cells 6 lower than the height of the upper end portion of the outer peripheral wall 3a. A notch recess 29 of the defining member 27 similar to the previous period in which 28 is integrally molded can be fitted so as to straddle the connecting rib 9.
[0064]
In these modified examples, the lower side of the reinforcing member 11 may be shorter than the inner cell bottom surface 6 b in each cell 6.
[0065]
Further, the difference in height between the upper end portion of the outer peripheral wall 3a, the peripheral rib 4, the connecting rib 9, the cell forming vertical side wall 5 and the reinforcing member 11 in the mat frame 2 is not particularly limited. In planting, it may be preferable to form the connecting ribs 9 and the cell forming vertical side walls 5 lower by 10 to 20 mm than the upper ends of the outer peripheral walls 3a and the peripheral ribs 4.
[0066]
That is, when the connecting rib 9 and the cell-forming vertical side wall 5 are made lower than the upper end portions of the peripheral rib 4 and the outer peripheral wall 3a, the lightweight growing material 8 (plant growing material) is connected to the connecting rib 9 and the cell-forming vertical side wall 5. When the cut turf is lined up on the upper surface and finished with joints, the tip of the cut turf can be made substantially flush with the upper end of the peripheral rib 4 and the outer peripheral wall 3a. It is possible to improve the appearance.
[0067]
When the reinforcing member 11 is used, it can be reinforced by increasing the strength against the pressure from the upper part of the mat frame 2, so that maintenance and inspection when mat frame 2 is laid, when planting mat 1 is laid, or after laying is completed When the upper part is walked, the mat frame 2 is prevented from being damaged, and the roots of plants such as lawn in the planting mat 1 are alleviated. Moreover, it can prevent that the lightweight growth material 8 moves within the cell 6, and can always keep the lightweight growth material 8 in favorable conditions with respect to plant growth.
[0068]
Next, the manufacturing method of the planting mat by this invention is demonstrated. When the planting mat 1 is manufactured, the filter 10 is laid on each cell 6 of the mat frame 2 or the cell bottom surface 6b of the defining portion 14 prepared in advance, and a light weight growing material 8 as a plant growing material is spread on the filter 10. The binder solution is sprayed on at least the surface of the lightweight growth material 8 and dried.
[0069]
Specifically, an example of the manufacturing process of the planting mat 1 is as follows (see FIG. 10). First, a wall-shaped reinforcing member 11 is fitted into each cell 6 of the mat frame 2 with a separate cross-shaped cross section, and fits to the bottom surface of the defining portion 14 in the defining portion 14 partitioned by the reinforcing member 11. A filter 10 (not shown) having a shape is laid, and a lightweight growth material 8 is packed on the filter 10. Next, an alginic acid solution serving as a binder is sprayed on the surface of the light weight growing material 8 so that at least the surface portion of the light weight growing material 8 is not separated and scattered. Then, hot air is applied to the surface of the light-weight growing material 8 to dry the spray solution to fix the surface of the light-weight growing material 8. Finally, the seed sheet 23 is placed on the surface of the lightweight growing material 8, and the stopper 24 is inserted into the small hole 13 on the upper surface of the reinforcing member 11 to fix the seed sheet 23.
[0070]
The planting mat 1 is completed through the above steps. And after laying in the required location which uses the planting mat 1, the germination preparation is completed by supplying water to the upper surface of the seed sheet 23 mounted.
[0071]
In addition, although the manufacturing process of said planting mat 1 is an example using the seed sheet | seat 23, mounting of the seed sheet | seat 23 was laid in the laying place in the manufacturing factory or after carrying in to the laying place. It is always possible later. This is the same when seeding on the surface of the lightweight growing material 8 or when planting a ground cover plant such as cut grass without using the seed sheet 23.
[0072]
In addition, when the seed or seed sheet 23 is placed or fixed on the surface of the light growth material 8, it is preferable to spray the binder solution again on the upper surface so that the seed or seed sheet 23 does not fly due to wind or the like. In some cases, sowing or placing and fixing the seed sheet 23 may be performed first, and then the binder solution may be sprayed and dried.
[0073]
And when laying the planting mat 1, laying appropriately on an artificial ground, laying on a waterproof sheet, a root-proof sheet, a water retention sheet, or in combination with an irrigation device, etc. The method is acceptable.

【The invention's effect】
The planting mat of the present invention and the method for producing the same have the effects of reducing the load burden on the laying surface and facilitating production, transportation, construction, removal and the like by the above-described configuration. Therefore, when laying, the cost can be greatly reduced, and the construction period can be completed in a short period of time. At the same time, the artificial ground can be returned to the state before laying at the time of removal.
[0075]
And while preventing the reduction | decrease of a soil, it has an effect which can always keep the soil used as the culture medium of a plant by preventing the pressure of a soil on favorable conditions.
[0076]
Furthermore, the planting mat of the present invention can be sowed and planted in advance not only after planting facilities have been laid but also in the manufacturing stage, and has the effect of meeting the diverse needs of consumers.
[0077]
Accordingly, it is possible to provide a growing environment in which greening plants suitable for greening small spaces scattered on the rooftops of buildings and cities can be provided over a long period of time, which contributes to simple greening of urban spaces.
