Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method for laying an artificial lawn.

[Conventional technology]

Recently, artificial turf has been laid in tennis courts, baseball fields, etc. instead of planting natural turf.

Conventionally, in order to lay an artificial lawn, mesh-shaped slatted blinds are laid on the ground, and on top of the slats, an artificial turf with a cut pile-like raised surface is laid on the surface of the base material layer. Two pieces of artificial turf are joined together by applying adhesive to the back side of the ground or by backing it with adhesive tape.

[Problems to be Solved by the Invention] However, when the edges of the artificial turf are joined in this way, the joint is weak, and the external pressure caused by kicking, stepping, etc. due to the player's movement is applied to the artificial turf. When repeatedly applied to the surface, the joints of the artificial turf often peeled and peeled, requiring repair.

For this reason, the ends of the artificial lawn are sutured with thread or the ends of the artificial lawn are sutured and glued together, but in this case, the work of suturing the joints is troublesome; Moreover, there is a problem in that the raised nap falls off from the base material layer at the seamed portion of the joint.

This invention was made to solve the above-mentioned problems, and the joint part does not peel and turn over, the joining work is easy, and the nap does not fall off from the base material layer. The purpose is to provide a method for laying an artificial lawn.

[Means for solving problems]

In order to achieve this object, the present invention provides a method for laying an artificial lawn, in which the artificial lawn is provided with a base material layer, cut pile-like naps and loops provided alternately in a striped manner on the base material layer. The base material layer of the two artificial turf areas is laid with the edges of the two artificial turf areas abutting each other on a base plate having at least two rows of needles on the substrate. Insert the needle into the part where the loop-shaped nap is provided.

[Operation] In this method of laying an artificial lawn, two sheets of artificial lawn are laid on the base plate with their edges butted against each other, and a needle is inserted into the part of the base material layer where the loop-shaped raised part is provided. Then, the edges of the two artificial lawns are joined together.

〔Example〕

FIG. 1 is a cross-sectional view for explaining the method of laying an artificial lawn according to the present invention, and FIG. 2 shows a part of the base plate used in the method of laying an artificial lawn explained with reference to FIG. FIG. In the figure, 1 is a substrate made of galvalume steel plate, 2 is a needle provided in four rows on the surface of the substrate 1, and the needle 2 is formed by making a notch in the substrate 1 and bending that part. It is inclined toward the center of the substrate 1. The substrate 1 and the needles 2 constitute a base plate 3. 5 is a base material layer made of resin such as vinyl chloride; 6 is a cut pile-like nap provided on the surface of the base material layer 5; 7 is a loop-like nap provided on the surface of the base material layer 5; The raised hair 6 and the loop raised hair 7 are provided alternately in a striped pattern,
Base material layer 5, loop-shaped nap 6, loop-shaped nap 7
This constitutes artificial lawn areas 4a and 4b. Then, a needle 2 is inserted into a portion of the base layer 5 of the artificial lawn 4a, 4b where the loop-shaped nap 6 is provided.

In this artificial lawn laying method, after laying the base plate 3, the artificial lawn 4 is placed on the base plate 3.
Butt the ends of a and 4b and place the artificial lawn area 4
The abutting surfaces of a and 4b are placed in the center of the base plate 3, and the loop-shaped nap 6 of the base layer 5 is laid.
Since the ends of the artificial lawns 4a and 4b can be joined by simply inserting the needle 2 into the part where the artificial lawns 4a and 4b are provided, it is extremely easy to join the ends of the artificial lawns 4a and 4b. can. Further, since the needle 2 is inserted into the portion of the base material layer 5 where the loop-shaped nap 7 is provided, the cut pile-shaped nap 6 does not fall off the ridges, and furthermore, the loop-shaped nap 7 is inserted into the needle 2.
Since the head of the needle 2 is wrapped around the needle 2, no damage is caused to the human body, and when external pressure is repeatedly applied to the surface of the artificial lawn 4a, 4b, the head of the needle 2 is bent as shown in FIG. Artificial lawn area 4a, 4
b is fixed to the substrate 1, the artificial lawn area 4a,
The joint part 4b will not peel off and turn over.

In the above embodiment, the needles 2 are provided in four rows on the substrate 1, but the needles may be provided in at least two rows. Further, by bonding the substrate 1 and the back surfaces of the artificial lawns 4a, 4b with adhesive or adhesive tape, the ends of the artificial lawns 4a, 4b can be more firmly joined.

〔Effect of the invention〕

As explained above, in the method of laying an artificial lawn according to the present invention, the joint part does not peel off and turn over, and the joining work is easy.
In addition, the nap of the artificial lawn will not fall off in the ridges.
As described above, the effects of this invention are remarkable.
