Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial ground. More specifically, the present invention relates to an artificial ground suitable for building lawns or breeding vegetation such as flowers on the roof of a building, on a veranda, or in a park, a plaza, and a stadium. FIG. 8 shows an example of a conventionally known pallet for artificial ground. The conventional artificial ground pallet 51 shown in FIG. 8 is formed as a square box (box) having an open upper surface, and soil is put in the box.
Plants such as turf and flowers are planted thereon, and are laid side by side on the roof of a building, on a veranda, or in a park, a plaza, or the like, to form an artificial ground. Also,
When turf is planted, it is known that a human can walk on these pallets 51. In FIG. 8, reference numeral 52 denotes a drain hole formed in the pallet. [0003] However, in such a conventional pallet 51, if the size of the box is formed too small, storage of water and nutrients cannot be secured, and the growth of vegetation deteriorates. . On the other hand, if the cell is too large, there is a problem that when a person walks on, shoes and the like enter the pallet 51 as they are and stomach the soil, thereby deteriorating the water retention function and deteriorating rooting. The present invention has been made to solve such a problem, and its purpose is to prevent a person or the like from stepping on the ground even when walking on the ground, and to ensure a proper water retention and drainage. In addition, the present invention provides an artificial ground having a structure capable of sufficiently securing rooting. [0005] The artificial ground of the present invention is provided at an interval capable of receiving the lower surface of the foot of a person who walks on a pallet formed in a predetermined size. A plurality of pins are provided so as to protrude upward from the upper surface of the pallet, and are provided near the outer periphery of the pallet.
The distance between the pins to be placed in
The distance between the pins is smaller than that of the pins, and soil is laid on the pallet up to the height of the pins. With this configuration, even if a person walks on the pallet, the lower surface of the shoe is received by the pins, and the ground is not stepped on, so that water retention and drainage can be ensured . Also, in particular,
Reduce the distance between pins located close to the outer circumference
Can also serve as a side frame, inside the pallet
Around the outside of the pallet
Can be prevented by a close pin. Also complete sidewalls
Drainage from the gap between the pins.
As well as through the gap between the pins
It is possible to make the roots well inside the pallets as well.
I can . [0008] Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which the artificial ground according to the present invention is applied to a roof garden. In FIG. 1, on the roof of a building, a sheet 12 having moisture-proof properties is laid on the entire surface of a concrete layer 11 forming the roof, and pallets 13 are regularly arranged on the upper surface thereof. The soil is put on top, and the soil can be used to plant vegetation. 2 to 4 show the pallet 13 of FIG. 1 alone, FIG. 2 is a perspective view thereof, FIG.
FIG. 4 is a sectional view taken along line AA of FIG. 2 to 4, a pallet 13 is a rectangular plate-like base portion 1.
3a. A side frame 13b is formed integrally with the outer peripheral portion of the base portion 13a over the entire periphery, and is formed in a box shape having an open upper surface as a whole. The base 13a in this example is formed, for example, in a square shape, the length of one piece is about 1 meter, and the height of the side frame 13b is 8 to 1
0 centimeters. However, these shapes or dimensions are set arbitrarily. For example, the length of one piece of the base portion 13b may be set to about 33 cm. In this way, an area of about 1 meter can be created by laying out three pallets 13 in the vertical and horizontal directions, and the pallets 13 can be further expanded in the vertical and horizontal directions. The material of the pallet 13 is a resin material, a stone material,
Metal materials and the like are used. [0010] Further, the base portion 1 surrounded by the side frame 13b.
A plurality of pins 14 made of metal, a resin material such as polypropylene or acrylic, and a plurality of stone materials are substantially provided inside the base 3a so as to protrude straight upward from the upper surface of the base portion 13a. They are arranged at equal intervals. Each of the pins 14 is press-fitted into the through-hole 15 of the base portion 13a and attached.
Is approximately equal to the height of the side frame 13b,
Or it is set slightly smaller. The intervals between the pins 14 are set to have an appropriate density such that the sole can be supported and supported by the plurality of pins 14 when a person rides on the base portion 13a with shoes or the like. The arrangement of the pins 14 is not limited to a linear arrangement, but may be, for example, a staggered arrangement. In addition, a plurality of holes 16 for draining water are provided in the base portion 13a and the side frame 13b, so that water in the pallet 13 can be drained through the holes 16. [0011] The pallet 1 thus constructed
3 is handled in a unitized state by attaching the pins 14 to the pallet 13, carried to a position where an artificial ground is to be formed, and arranged regularly, and then, when the soil is put through the opening on the upper surface, the artificial ground is formed. . FIG. 1 shows a state in which the pallets 13 are arranged on the surface of the concrete layer 11 forming the roof of the building, and the soil 18 is put in the pallets 13. The amount of soil to be put into the pallet 13 is preferably the same height as the pins 14 or a position slightly lower than that. Thus, the pallet 13
In the artificial ground formed by putting soil inside,
Plants 17 such as grass and flowers can be planted between them. In the artificial ground formed by laying the pallets 13 as described above, the following effects can be expected. -When a person walks on the floor, the sole is supported by the plurality of pins 14 protruding from the soil and the upper surface of the side wall 13b, so that the soil is not directly crushed by the shoes.・ Since humans do not step on the soil even when walking on top, drainage can be obtained well and root rot can be eliminated. In addition, conversely, the rooting of the vegetation can be improved, and this can have a positive effect on the growth of the vegetation.・ Since humans will not step on the soil even when walking on top of the soil, less soil is required, and the amount of soil put in the pallet can be reduced to reduce the weight and reduce the effect on the physical strength of the building. it can. Next, a modified example of the pallet 13 according to the present embodiment will be described with reference to FIGS. 5 to 7
5 shows a pallet alone, FIG. 5 is a perspective view thereof, FIG. 6 is a top view thereof, and FIG. 7 is a sectional view taken along line BB of FIG.
The configuration of the pallet in this modification is such that the side frame 13b provided on the pallet 13 shown in FIGS. Since the other structures are the same as those in FIGS. 1 to 4, the same members will be described with the same reference numerals. In FIGS. 5 to 7, the pallet 13
It is formed as a rectangular plate-like base portion 13a. Here, the length of one piece of the base portion 13a is also about 1 meter, which is arbitrarily set, and a resin material, a stone material, a metal material, or the like is used as a material of the pallet 13. A plurality of pins 14 made of metal, resin material, stone, or the like are provided on the base portion 13a at a substantially equal interval so as to protrude straight upward from the upper surface. I have. Each of the pins 14 is attached by being press-fitted into a through hole 15 provided in the base portion 13a, and the protrusion amount from the upper surface of the base portion 13a is about 8 to 10 cm, which may also be set arbitrarily. Things. Further, the interval between the pins 14 is determined by the human
An appropriate density is set so that the sole can be supported and supported by the plurality of pins 14 when the shoe 3a is put on the pallet 13a shown in FIGS. The configuration is the same. A significant difference from the pallet 13 shown in FIGS. 1 to 4 is that the interval between the outermost pins 14 is smaller than the interval between the inner pins 14. That is, of the pins 14 provided on the base portion 13a, the outermost pin 14
Is set to about half of the interval between the pins 14 provided inside. With this narrow spacing of the pin 14, it is possible that serve as the side frames outside the pin 14, the soil was placed inside without side frame is prevented flowing out. The arrangement of the pins 14 does not have to be a linear arrangement, but may be, for example, a staggered arrangement. The pallet 13 thus constructed
Also, the pins 14 are attached to the pallet 13 and are handled in a unitized state. After the pins 14 are transported to a position where an artificial ground is to be formed and regularly arranged, and then soil is put in from above, an artificial ground is formed. The amount of soil put in the pallet 13 is the same as in the case of the pallets shown in FIGS.
It is preferable that the position be the same height as the pin 14 or a position slightly lower than the same. In the artificial ground formed by putting the soil in the pallet 13 in this manner, the pins 14 and 14
A vegetation 17 such as turf and flowers can be planted in between. In the artificial ground formed by laying the pallets 13 as described above, the following effects can be expected. -When a person walks on the sole, the shoe sole is supported by the upper surface of the plurality of pins 14 projecting their heads from the soil, so that the soil is not directly stepped on by the shoes.・ Since humans do not step on the soil even when walking on top, drainage can be obtained well and root rot can be eliminated. Further, the rooting of the vegetation can be improved, and this can have a positive effect on the growth of the vegetation. Also, since the outermost pins are narrowed so as to serve also as side frames, there is no need to provide drain holes in the side portions, and the manufacturing can be simplified.・ In addition, since the outermost pins are narrowed to form a structure that also serves as a side frame and not a completely closed side frame, the roots of planted vegetation are free to the next pallet. And can have a positive effect on the growth of the vegetation.・ Since humans will not step on the soil even when walking on top of the soil, less soil is required, and the amount of soil put in the pallet can be reduced to reduce the weight and reduce the effect on the physical strength of the building. it can. As described above, according to the present invention, even if a human or the like walks on the ground, it does not squeeze on the ground, and furthermore, it is possible to secure a suitable water retention and to drain the water, and the rooting is sufficient. Thus, it is possible to obtain an artificial ground having an extremely excellent effect, for example, it is possible to secure the artificial ground.
