Abstract

PROBLEM TO BE SOLVED: To perform laying of an artificial lawn without needing an under pad and the execution of an elastic pavement work by a method wherein one layer or a laminate plate-form mat member being light and high in impact absorbing ability is laid as a ground pavement material. SOLUTION: Both surfaces of an elastic layer being light and high in impact absorbing ability solidified by rocky processing finishing are laid on a bed rock 1 or a road bed 2 formed on the bed rock 1 or a plate-form or belt-like mat member 5 wherein a comparatively hard upper layer us adhered on a soft lower layer is laid as a bedding pavement material. The adjoining mat members 5 are joined together by a tacker, a boundary is closed with an adhesive tape or, or the mat members are laid in a state that not difference in level is produced by inserting the edge of the mat member 5 in dents on both sides of a rail member in an I-shape in cross section, and artificial lawns are laid thereon. In a case that a water impermeable mat member 5 is used, drain holes are arranged in a dispersed state. Since a need for elastic pavement is eliminated, the execution of a work is practicable on the bed rock where a vehicle for conveying a mixed substance and pavement machine are not arranged since there is no need for elastic pavement.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for laying artificial turf on a physical education facility, an exercise facility, or a passage structure.
The present invention relates to a method of forming a base pavement for artificial turf on a base or a roadbed formed on the base, and laying the artificial turf on the base pavement.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 1, a crushed stone roadbed 2 is laid on a base (roadbed) 1 for laying artificial grass on the ground of a physical education facility, an exercise facility, a school ground, or a passage structure.
Is constructed in a thickness of about 50 to 150 mm, and at least one of asphalt pavement, concrete pavement, or elastic pavement is provided as a base pavement 3 for artificial turf directly on the crushed stone bed 2 or on the base. The artificial turf 4 was laid on such a base pavement 3 with a thickness of about 30 to 50 mm. The ground pavement 3 forms a mixture as a kneaded material obtained by adding each binder to natural aggregates or rubber chips having different particle diameters in the vicinity or on site, and the mixture is formed into a crushed stone roadbed 2.
It needed to be spread over, spread, leveled and compacted.

[0003]

However, asphalt pavement and concrete pavement in the conventional base pavement harden and harden after construction, and lack cushioning properties even when artificial turf is constructed thereon. We needed an underpad for artificial turf.

[0004] In the case of asphalt pavement, concrete pavement, or elastic pavement, the spread paving of the mixture requires a vehicle for transporting the mixture and a paving machine, and these heavy vehicles and paving machines cannot be arranged. Construction on the foundation was not possible.

[0005] Further, the kneaded mixture hardens or solidifies within a few hours after kneading, and thus cannot be stocked such as a kneading reservoir.

Further, the density of the material to be used is 2.3 to 2.4 g / asphalt pavement or concrete pavement.
Because of its large size of cm ³ , it was difficult to adopt it in places where a large overload could not be obtained.

Further, in the case of asphalt pavement and concrete pavement, there is a problem that it is extremely difficult to pile a tent when a tent is temporarily installed with a ground as an evacuation site in the event of a disaster.

[0008] It is therefore an object of the present invention to provide a method of laying artificial turf which overcomes the above-mentioned disadvantages of conventional pavements such as asphalt pavement, concrete pavement or elastic pavement.

[0009]

In order to achieve this object, the method for laying artificial grass according to the present invention is characterized in that the base pavement uses at least one layer of a plate-like or band-like mat material as a base pavement material. It is characterized by being formed by laying.

In a preferred embodiment of the present invention, the mat member is formed of a lightweight mat material having a low specific gravity, and the mat member is formed by laminating at least two layers. It is good to use a layer having high properties.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described with reference to the drawings.

As a preferred embodiment of the present invention, as shown in FIG.
And a plate-like or band-like mat member 5 having a thickness of, for example, about 10 to 30 mm on the roadbed 2 or directly on the base 1.
Laying. For example, the artificial turf 4 containing sand is laid on the mat member 5.

As the mat member 5, for example, as shown in FIG. 3A, a mat having an outer layer 7 in which both surfaces of an elastic layer 6 made of, for example, rock wool having a high shock absorption property are hardened by flocking processing is used. 3B, or as shown in FIG. 3B, a relatively hard upper layer with an adhesive 9 on the flexible lower layer 8, that is, an upper layer having a hardness capable of self-retaining the shape and supporting a certain load. It is preferable to use a laminated mat to which the layer 10 is adhered.

FIG. 4 shows a state in which a number of plate-like mat members 5 are laid out. Tackle 1 between adjacent mat members
1 and the boundary may be closed with an adhesive tape 12. Alternatively, the edge of the mat member 5 may be inserted and held in the depressions on both sides of the web of the I-shaped cross section rail-shaped member 13. In the case of the I-shaped rail-shaped member 13, there is an advantage that a step is not generated between the adjacent mat members 13.

If the mat member 5 is not a water-permeable mat, it is preferable to disperse the drain holes 14 as shown in FIGS. 5 (a) and 5 (b).

[0016]

According to the method of the present invention, there is no need for a vehicle or a pavement machine for transporting a mixture for asphalt pavement, concrete pavement, or elastic pavement as in the case of a conventional base pavement, and a light plate or band is used. It is only necessary to lay the mat materials of the above, and it is also possible to perform construction on a base on which these heavy vehicles and paving machines cannot be arranged.

According to the method of the present invention, there is no need to worry about the hardening or solidification of the kneaded mixture as in the conventional method, and the mat material can be freely stocked.

Further, according to the method of the present invention, since the density of the mat material used is as small as about 1.5 g / cm ³ , it can be easily applied even to a roadbed having a relatively low supporting force. It is also possible to work in places where a large load cannot be obtained.

Further, there is an advantage that it is extremely easy to pile a tent when a tent is temporarily installed with the ground as an evacuation site in the event of a disaster.

Further, by forming the mat material into a laminate and forming one of the layers as a layer having high shock absorption, it is not necessary to lay an underpad or to construct an elastic pavement as in the conventional construction method. .
