Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural turf formed on the floor of various stadiums such as soccer fields and rugby fields, or the surface of park sites.

[0002]

In recent years, artificial turf is often used in place of natural turf because of its ease of management, but artificial turf may not be used in certain competitions due to competition regulations. Also, scratches and the like are likely to occur, which is a safety problem. Especially, in terms of nostalgia for nature, artificial grass is not enough. However, since natural grass requires proper management such as sunshine, ventilation, and moisturizing, it takes a lot of time and effort to grow and manage it. Especially in the case of covered stadiums, etc., it is difficult to secure an appropriate training environment.
Applicability of natural grass is being questioned. In addition, maintenance of rough grass requires complicated work, and it takes a long time to regenerate it before it can be used, and it becomes difficult to use it during that time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. <B> Structure of natural grass floor unit (FIGS. 2 to 4) FIGS. 2 and 3 show a natural grass floor unit. In the figure, 1 is a vegetation substrate 1 made of lightweight concrete or the like. Vegetation board 1
The shape is prepared to be an arbitrary shape in conformity with the place where the natural turf floor is to be formed. In the present embodiment, the case of a square will be described. In addition, the vegetation substrate 1 is provided with a hanging jig for hooking a lifting wire or the like when moving. Although various structures can be adopted for the hanging jig, for example, as shown in FIG. 2, when the triangular corner portions 11 are raised at four corners of the vegetation substrate 1 and the hook portions 12 such as wires are provided on the upper surface, As shown in FIG. 4, it is conceivable that the four corners of the vegetation substrate 1 are chamfered and the T-shaped metal fitting 14 having the hanging hole 13 is fixed thereto. Furthermore, the top surface of the vegetation substrate 1 is provided with irregularities for mooring soil. For example, as shown in FIGS. 2 and 3, various methods are conceivable, such as a structure in which a resin spiral cord 2 is attached to the upper surface of the vegetation substrate 1 in a grid pattern, or a case where the upper surface of the vegetation substrate 1 itself is uneven. To be Then, soil 3 is spread on the upper surface of the vegetation substrate 1, and natural grass 4 is rooted in the soil 3 to form a natural grass floor unit. At this time, since the soil mooring means is provided on the vegetation substrate 1 as described above, the natural grass 4 can be prevented from falling off together with the soil 3, and an integrated natural grass floor unit can be obtained. it can.

<B> Structure of the growing room (FIG. 5) In the growing room 5, an environment suitable for growing the natural grass 4 is maintained. For example, as shown in FIG. 5, the growing room 5 is divided into a plurality of rooms by a floor plate 51, and an artificial solar irradiation device 51 is installed on the ceiling of each room. In addition, a ventilator and a humidifier (not shown) for maintaining proper ventilation and moisture retention are installed in each room.

<C> Creation and dismantling of natural grass floor (FIG. 1) When creating a natural grass floor using the natural grass floor unit configured as described above, as shown in FIG.
The construction can be easily performed by hooking the wire of the crane, etc. on the hanging jig and hoisting it, and laying the required number of pieces at a predetermined place. After the unit is laid on the exposed portion of the triangular corner portion 11, a small piece formed by rooting natural grass on the cushion material may be covered and hidden from above. When disassembling, it can be easily performed in the reverse order of the above. As another transportation method for the natural turf floor unit, several small holes are opened in the vegetation board 1, and the air ejection portion of a commercially available portable air tank is inserted into these holes.
It is also conceivable that the air may be jetted downward to float and move from the floor surface. In this case, since a heavy machine such as a crane is not required, the lawn is not damaged, there is no risk of dropping, etc. Further, since a hanging jig is not required, the portion without the lawn can be reduced.

<D> Cultivation of natural turf When cultivating the natural turf 4, some or all of the natural turf floor units laid as described above are removed and stored in the cultivating room 5 to keep a good condition. Can be raised in the environment. When the natural grass 4 becomes rough, the unit can be removed and replaced with a complete natural grass floor unit stored in the growing room 5 for easy maintenance. The rough natural turf bed unit can be stored in the growing room 5, regenerated, and reused.

[0008]

[Embodiment 2] As shown in FIG. 6, a pipe 71 is laid in the lower part of the floor where the natural grass floor unit is installed to provide a water supply / drainage plant 7, and water and nutrients are supplied to promote the growth of natural grass. It is also possible to do. In this case, as shown in FIG. 7, the structure of the natural grass floor unit is such that a water-permeable mat is stored in a water-permeable box-shaped frame body 72 made of a perforated plate or the like, and the natural grass 4 is Use rooted ones. The structure of the mat includes three layers of a cushion mat 73 that protects the natural grass 4, a root growth mat 74 that is a root growth area, and a watering mat 75. On the other hand, floor equipment 76 for installing natural grass floor units
Has a hollow portion, and has a water-permeable structure in which a large number of holes and the like are opened on the upper surface. Then, it is configured so that water and nutrients can be supplied to the natural grass 4 through the pipe 71 laid on the lower part of the floor surface.

[0009]

Since the present invention is as described above, the following effects can be obtained. <a> Natural turf floors can be easily and quickly created by simply laying a plate-like natural turf bed unit on the floor surface to be constructed such as in a stadium.

<B> It is possible to remove all or part of the spread natural grass floor unit and store it in the growing room to always grow it in a good environment. Therefore, even when it is used in a covered stadium or the like, it does not affect the growth of natural grass and can be applied.

<C> When the grass becomes rough, the unit can be removed and replaced with a complete natural grass floor unit stored in the growing room for easy maintenance. In addition, it can be used without any training period, and the operating rate is improved. The rough natural grass floor unit
It can be stored again in the growing room for regeneration and reused.

<D> Since the natural grass floor unit can be dismantled simply by removing it, it is possible to easily change to a floor structure other than grass.

<E> Even in places where it is not possible to stretch grass normally, it is possible because the natural grass floor unit is simply installed, and the applicable range is expanded.

<F> Since the shape of the natural turf floor unit can be changed to any shape, the natural turf floor unit can be installed according to the installation place such as the corners and the periphery of the pillars, which improves the workability. Can be planned.

<G> By constructing the storage frame of the natural grass and the floor surface of the installation place so that water can pass therethrough, and by providing a water supply / drainage plant below it, it is possible to reliably control the supply of water and nutrients. It is possible to promote the growth of natural grass.
