Description

Artificial turf structure for golf green

The present invention relates to a structure of artificial turf, and more particularly to a structure for the golf green structure to prevent the loss of the filling layer due to rain and running water and to control the surface uniformity of the green.

Recently, due to the rapid development of social sports, the population using sports facilities for leisure or health is increasing rapidly. As a result, sports facilities are increasing rapidly and are still expanding. Although there are various kinds of facilities in the sports facilities, artificial turf is frequently used in terms of complementing durability and homeostasis, which are disadvantages of natural grass.

In particular, artificial turf is often installed outdoors. In this case, it requires rapid drainage for rainwater and running water. Maintenance of the flatness characteristics is required.

For this purpose, the golf course structure required by the USGA Green Section requires that the composition be composed of a planting layer 10, an intermediate layer 20, and a drainage layer 30 having a total depth of 45 cm, as shown in FIG. As an example, a four-layer structure consisting of two layers of drainage layers 31 and 33 has also been proposed. outside)

Although the structure according to the above methods has considerations regarding drainage and the like, there are no considerations regarding pressure resistance and surface flatness. Accordingly, there is a desire for a new golf green substructure that can maintain the flatness by preventing the lower soil from being lost due to the user's pressure or rain.

In order to solve the above problems, the present invention is to provide an artificial turf structure for preventing the loss of the artificial turf structure by excellent for golf green, and improved pressure resistance.

In addition, the present invention provides an artificial turf structure that can prevent the loss of the structure to maintain the flatness and uniformity of the surface.

In order to achieve the above object of the present invention, in the structure of artificial turf for golf green, artificial grass pile yarn, the filling layer in which the pile yarn is planted, the upper ground layer formed on the lower portion of the filling layer, the lower portion of the upper ground layer A lower ground layer formed on the upper ground layer, wherein the upper ground layer is formed of a nonwoven fabric layer at a boundary between the sand layer and the masato layer, and a protective member that divides the sand layer and the masato layer, and the upper ground layer and the lower ground layer; The lower ground layer provides an artificial turf structure including a crushed stone layer and a drain pipe.

In another aspect, the present invention provides an artificial turf structure in which the protective member is made of a triangular to hexagonal shape.

In addition, the present invention is made of a fiber material, the protective member provides an artificial turf structure formed of a nonwoven fabric.

In addition, the present invention is the filler layer is a polymer pad layer of water permeability; Bubble layer for simulating a grass pile on the pad layer; And an artificial turf structure including circular cross-section yarns and hetero-cross-section yarns 1: 1 or alternately formed piles in the bubble layer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted so as not to obscure the subject matter of the present invention.

As used herein, the terms "about", "substantially", and the like, are used at or near the numerical values when the manufacture and material tolerances inherent in the meanings indicated are intended to aid understanding of the subject innovation. Accurate or absolute figures are used to assist in the prevention of unfair use by unscrupulous infringers.

2 is a cross-sectional view of a structure according to a preferred embodiment of the present invention, Figures 3a and 3b shows a detailed view of the protective member of the upper ground layer of the structure.

Structure according to a preferred embodiment of the present invention is artificial grass pile yarn 100, the filling layer 200 in which the pile yarn is planted, the upper ground layer 300 formed on the lower portion of the filling layer, the lower ground layer 400 formed on the lower portion of the upper ground layer It can be formed as.

The upper ground layer 300 may include a protection member 350 that divides the sand layer 310 and the masato layer 330 and the sand layer 310 and the masato layer 330, and a boundary layer 370 at a boundary portion between the upper ground layer 300 and the lower ground layer 400. The layer 400 may be formed of the crushed stone layer 410 and the drain pipe 430.

The filling layer may be proposed in various forms according to the structure of the artificial turf, and as described in the present specification, the non-filling artificial turf may be used. The upper ground layer 300 may be filled with the sand layer 310 and the masato layer 330 divided by the protective member 350 by the protective member 350. (See FIG. 4) The protection member may be embodied in various forms, such as three angles, four angles to six angles, and preferably have a six angle shape. Therefore, the sand and masato layers may be filled with materials partitioned by the protective member. This helps to maintain the level of the upper ground during the ground construction, and can shorten the construction time, and since the sand and Masato are separately divided and filled after installation, it prevents the sand from being lost by running water. give. In addition, the ground material is often pushed to the side by the back pressure before and after construction, which often causes surface curvature, which is a very important factor in the golf green, which prevents the side from being pushed to the side of sand by the protection member. The pressure resistance is greatly improved.

In addition, the protective member may be a textile material, preferably a non-woven fabric. The reason for selecting the fiber material as the protective member in the structure of the present invention is that the flexibility of the fiber can be used before the construction, so that the construction can be performed regardless of the installation area or the environment of the site, and the problem is caused by the structure after the construction. In this case, the fiber has an advantage of preventing the loss of sand and masato due to denser tissue density due to an increase in physical properties related to strength such as tensile strength during absorption or absorption.

The boundary layer 370 located at the boundary between the upper ground layer 300 and the lower ground layer 400 is to prevent sand or masato from the upper ground layer from leaking into the lower ground layer, and may be made of a woven or nonwoven fabric.

As described above, the structure of the artificial turf for golf green according to the embodiment of the present invention can secure the surface flatness, and can prevent the ground material from being pushed to the side due to the pressing force. It has a sustainable effect.

In addition, the structure according to the present invention can prevent the ground filling material from being lost by rainwater, and has the advantage that the strength is further improved.

Through the following examples will be described in more detail.

Example 1

A water-permeable PVC pad layer is formed on the water-permeable ascon base layer, and a non-woven bubble layer is formed as PP on the pad layer. A pile was formed in the bubble layer alternately by 1 (tufting method). The pile has a density of 32 per 5 inches long and 6.8 per 1 inch wide.

A sand layer was formed at about 10 cm below the artificial turf, and a masato layer was formed at 7 cm. At this time, the protective member was used as the hexagonal shape of the length of each side 7cm. Thereafter, a crushed stone layer and a drain pipe were respectively installed.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
