DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an artificial turf which can be easily used in any place such as a ground such as a ballpark, a golf course, and a tennis court, and a site such as a park, a courtyard, and a school yard. Artificial turf tiles used for.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing an artificial turf for the above-mentioned purpose, for example, as described in Japanese Patent Application Laid-Open No. 3-197703, First, a base material serving as a base layer is laid or bonded, and then a rubber chip containing a binder is filled and laminated thereon, and then an artificial turf layer is laid or bonded on the rubber chip layer to form an artificial turf. I was doing construction work.

[0003]

However, in the above-mentioned conventional method, all of the construction work must be performed at an outdoor site, and the work is affected by the weather, and the base or the base is required depending on the size of the site area. However, laying or bonding the artificial turf took a very long time, and the construction work could not be carried out smoothly in many cases.

Further, as described above, the work is divided into three stages of laminating a base layer, a rubber chip layer, and an artificial turf layer, and an adhesive or the like is required for laminating each of them, resulting in cost reduction. The work efficiency was extremely poor both in terms of time and effort.

[0005] Further, since the artificial turf once manufactured is fixed to the ground, for example, other ball games, such as baseball, can be played on the same site on the ground where the artificial turf is laid as a rugby field. It was difficult to do so, there was no ground that could be used as a rugby field and a baseball field, and almost no versatile use was possible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is an artificial turf which can be easily and inexpensively constructed. It is an object to provide a method and an artificial turf tile used in the method.

[0007]

The technical means taken by the present invention to solve the above-mentioned problem is that, as a method of constructing an artificial turf, a turf portion 3 is formed by weaving pile yarns 6 in a stitch shape. Next, a mixed liquid 11 of a rubber chip 4 and a binder 5 serving as a base 2 is filled and applied to the backing 9 side of the lawn 3 and dried and solidified for a predetermined time to integrate the lawn 3 with the base 2. The artificial turf tile A is formed, and then, the artificial turf is constructed by laying at least one artificial turf tile A at a predetermined site.

[0008] Further, the present invention is to solve the above-mentioned problems.
Then, the pile yarn (6) is woven into a stitch to form the grass (3)
Then, on the lining (9) side of the turf section (3), a base (2)
Filled with a mixed solution (11) consisting of chip (4) and binder (5)
And dried and solidified for a predetermined time, and the grass part (3) and the base (2)
To provide artificial turf tiles .

[0009]

The artificial turf of the present invention is constructed by forming a pile 3 by forming pile yarns 6 in a stitch pattern indoors, and then placing a rubber chip 4 serving as a base 2 on a lining 9 side of the turf 3. A mixed solution 11 of the turf part 3 and the base 2 is formed by filling and applying a mixed solution 11 of the turf part 3 and the base 2, and then the formed artificial turf tile A is formed. The artificial turf can be easily constructed simply by laying the artificial turf in a free shape on site.

An embodiment of the present invention will be described below with reference to the drawings.

When the artificial turf of the present invention is used in a tennis court T or the like, as shown in, for example, an enlarged view of FIG. 1G in FIGS. 1 and 2, the site is previously paved with asphalt concrete or cement concrete. Drainable substrate 1
And on it, the permeable artificial grass tile A according to the present invention
Are arranged side by side as appropriate and laid in the shape of a tennis court T for construction.

As shown in FIGS. 2 and 3, the artificial turf tile A comprises a block-shaped base ² of 1 m ^{2 to 2} m ² ,
2 and a turf section 3 mounted on the upper surface.

The base 2 includes various vulcanized rubber chips 4.
And a mixture of a known synthetic resin material such as polyurethane alone or a binder 5 made of a combination of two or more kinds.
As shown in FIG.
It is recessed in a grid every 30 cm ² .

The turf section 3 is a Russell-woven pile yarn 6.
7, a knitted weave, a knit weave, or the like, which is woven in a stitch shape to a size substantially the same as that of the base 2, and whose top end 8 is cut off.

The pile yarn 6 is made of a monofilament or a yarn made of polypropylene, polyethylene, nylon, polyester, polyvinylidene chloride, polyvinyl chloride, or the like, and has a pile length of 10 mm or more, preferably 15 to 45 mm, and a total length of 15 to 45 mm. Denier is 3000-1
Those having 0000d, preferably 4000 to 8600d are used.

The artificial turf tile A constructed as described above
It is very convenient to carry, and the Russell weave 7 is rich in cushioning properties and hardly suffers from damage due to friction.

Next, the production of the artificial turf tile A having the above-described structure,
An embodiment of the method for constructing an artificial turf of the present invention using the artificial turf tile A will be described.

When the artificial turf tile A having the above structure is formed, first, as shown in FIG. 5, the pile yarn 6 is made to have a size of about 1 m ^{2 to 2} m ² by Russell weave 7 or the like. The pile yarn 6 is woven in a stitch shape, and the tip 8 on the upper surface side of the pile yarn 6 is cut substantially flush to form the grass portion 3.

When the pile yarn 6 is subjected to Russell weaving 7, if the density is 3 gauge or more and 4 stitches or more, no damage due to friction or the like is caused at all, and the turf portion 3 becomes strong.

Next, as shown in FIG.
With the side 9 facing upward, place the grass part 3 on the formwork as shown in FIG.
6.9 kg of vulcanized rubber chips 4
And a mixed liquid 11 obtained by mixing 2.1 kg of a polyurethane resin binder 5 (rubber chip: binder is approximately 3: 1).
Then, in this state, air drying is performed or drying is performed by adding a curing agent, heat, or the like.

At this time, the mixed liquid 11 has not been solidified yet.
In the meantime, as shown in FIG.
Become. The grooves 13 to prevent warping and shrinkage
0cm ^TwoIs recessed in a lattice.

The mixture 11 is a mixture of the Russell weave 7
Gradually with going to penetrate into the stitch that is made equal, it is solidified by the absorption of water vapor by natural standing, substantially 1 m ² to 2 m ²
A base 2 having a size of about 10 mm and a thickness of about 2 mm is formed.

Thereafter, the base 2 is taken out of the mold 10 and
By turning the side to the lower surface, an artificial turf tile A in which the lining 9 side of the turf portion 3 and the base 2 are integrally connected as shown in FIG. 2 is formed.

The manufacturing process of the artificial turf tile A described above can be easily performed in a factory. Next, the plurality of artificial turf tiles A formed as described above are transported to a target site. At the site, as shown in FIGS. 1 and 2, the artificial turf tiles A are juxtaposed, and the artificial turf tiles A of various shapes, for example, adapted to the shape of a tennis court T as shown in FIG. I do.

At this time, in order to prevent friction and fix the artificial turf tile A, as shown in FIGS. 2 and 3, when the pile length is 10 mm to 20 mm, the pile length is about 25 kg / m ² and the pile length is about 25 kg / m ² . 30mm
In the case of 4040 mm, sand 48 of about 48 kg / m is put into the grass part 3 and laid at a certain height.

At this time, as shown in FIG. 1, an elongated artificial turf tile A (5 cm to 10 cm width) in which the turf portion 3 is dyed white is sandwiched between the square artificial turf tiles A. And the line C of the tennis court T.

The artificial turf of the present embodiment manufactured and constructed as described above can be obtained by merely rearranging the artificial turf tile A appropriately.
For example, by changing the tennis court T to a baseball field, soccer field, rugby field, etc., or by changing the number and shape of the artificial turf tiles A, the size and the like can be easily adjusted. This makes it versatile and can be used very reasonably.

In the case where a partial repair is required, the conventional construction method has to be entirely reconstructed. However, in the artificial turf of the present embodiment, only the portion requiring repair is artificially repaired. It can be repaired simply by replacing the turf tile A,
As a result, considerable cost reduction can be achieved.

The pile yarn 6 is preferably colored green as an artificial turf. However, as described above, the artificial turf tile A of the line C is separately colored as a white turf. It may be appropriately colored according to the purpose of use, for example, it may be manufactured by coloring a part of the artificial turf tile A into a white color and used as a line C or the like. By laying the artificially colored grass turf tile A, a design effect can also be exerted.

Further, the artificial turf tile A in the above embodiment is used.
The size, the weight ratio between the rubber chip 4 and the binder 5, the amount of laid sand, and the like can all be freely changed within the range intended by the present invention.

[0031]

According to the present invention, the turf portion is formed by weaving the pile yarn into a stitch shape, and then a mixed solution of a base rubber chip and a binder is filled and applied to the lining side of the turf portion, and the turf portion is filled and coated. The artificial turf tile in which the turf portion and the base are integrated is formed by drying and solidifying for a time, and then the artificial turf tile is laid at a predetermined site to construct the artificial turf. There is no need for any work such as laminating or bonding the materials, and the molding of the artificial turf tile is performed in the factory, and the artificial turf tile is simply laid at the site. Therefore, construction can be performed very easily without being affected by the weather, and cost and work efficiency can be sufficiently improved.

Further, the artificial turf of the present invention can be used for a variety of purposes on the same site just by changing or rearranging the number of artificial turf tiles to be used. Is easy, and it is possible to easily perform partial repairs simply by replacing only the parts that need repair.
Very reasonable use is possible.
