Embodiments of the present invention will be described below based on the drawings.

In the first embodiment shown in FIGS. 1 to 3, 1 is 1
In this artificial lawn structure, the support body 2A is made of a synthetic resin net material that is corrosion resistant and has appropriate elasticity and rigidity, and the support body 2A is made of a flexible synthetic resin material such as nylon that has wear resistance and corrosion resistance. A lawn leaf piece 3 is supported.

The grass leaf pieces 3 are formed by twisting a thin strip (flat yarn), and monofilament is also mixed in to improve the napping property. The parts are sewn and fixed to the support body 2A via an adhesive or a fastener 4. The bent portion may be sewn with cloth or a synthetic resin sheet wrapped therein as a patch. In addition, the method for manufacturing this lawn leaf piece 3 is to fold a long leaf material on a flat surface, sew the bent parts on both sides, and then cut the center to make two grass strips at once. Forms leaf discs.

The support body 2A is made of a single piece of net material (perforated plate material) by high-frequency processing or hot press processing, and includes a single protruding mounting portion 5 having an M-shaped cross section, and a grounding portion 6 extending from the lower side of the mounting portion to both sides. are integrally molded, and therefore, a through hole d is formed on the entire surface of the support body 2A. A substrate 7 made of a perforated flat plate is attached to the grounding portion 6 via an adhesive or a fastener.

There is. Since this attachment part 5 is long in the vertical direction, it ensures the attachment of the lawn leaf piece 3 and improves the uprightness.

The grounding parts 6 on both sides of the mounting part 5 are grounded to the ground 8,
The mounting part 5 is held upright on the ground 8, and in the embodiment, a board 7 is provided to maintain the shape of the support 2A, but the grounding part 6 is directly grounded without providing the board 7. You may.

Attachment portions 5 are provided at multiple locations in the longitudinal direction of the support body 2A.
A shape-retaining rib 9 is formed between the ground contact portion 6 and the ground contact portion 6 . This shape-retaining rib 9 is also integrally molded with the mounting part 5 and the grounding part 6, and the grounding part 6 is formed between the two mounting parts 5.
The supporting body 2A located above prevents the attachment part 5 to which the grass blade 3 is attached from falling down and helps maintain the shape during molding.This shape-retaining rib 9 is shown in FIG. As shown, by projecting upward from the grounding part 6 in an inverted U-shape and forming a bend, the grounding part 6 is easily deformed, albeit slightly, in the longitudinal direction (direction along the attachment part 5). If the method is perpendicular to that, it will be slightly difficult to deform, and the support body 2A will be attached to the mounting part 5.
This reduces the difficulty of deformation in the longitudinal direction, corrects excessive deformation in the direction perpendicular to the longitudinal direction, and improves the conformability of the cubic surface to the ground contact surface.

A large number of the artificial lawn structures 1 are arranged in parallel on the ground 8, and sand 10 is buried between the lawn blades 3 so that the mountain part a of the support 2A is hidden, thereby creating an artificial lawn of a required area. Make up the lawn. This artificial lawn structure 1 is stable due to the weight of the sand 10, does not easily float up or fall out, and especially when the roots of the natural grass are entangled, a stronger laying condition is obtained, and water permeability and drainage are good. Even if there is a curved surface, it can be laid to fit the curved surface.

In the second embodiment shown in FIGS. 4 and 5, the support body 2B is made by integrally molding a single porous plate material with a plurality of parallel mounting portions 5 by high-frequency processing or hot press processing, and between the mounting portions 5. serves as the grounding part 6, and by attaching the lawn leaf pieces 3 to all the attachment parts 5, an artificial lawn unit 11B of a constant area can be formed even before it is laid on the ground 8.

Therefore, this artificial lawn unit 11B is
An artificial lawn can be formed by simply placing it on a lawn and covering it with sand 10, making the laying work easier, increasing the shape-retaining strength, and better adapting to the curved surface 8' as shown in Fig. 6. becomes. In this embodiment as well, a common board may be attached to all the grounding sections 6.

In the third embodiment shown in FIG.
is made by bending a single perforated plate into the shape of a pulse signal.
A large number of attachment parts 5 having a U-shaped cross section and a grounding part 6 between the lower ends thereof are formed, and the lower part of the lawn leaf piece 3 is attached to one side of the attachment part 5 to form an artificial lawn unit 11C.

This support body 2C is easier to process than the support body 2B of the second embodiment, and grass blades 3 can be attached to both sides of the attachment portion 5.

〔Effect of the invention〕

According to the present invention described in detail above, the support body 2 is an artificial lawn support body in which strip-shaped grass blades 3 are planted and buried in sandy soil 10. Multiple parallel mounting parts 5 to be mounted
