Description

Artificial turf structure of artificial turf

The present invention relates to the artificial turf structure of the artificial turf field, more specifically, to the artificial turf structure of the artificial turf field is easy to install the sand-filled artificial turf field, the durability life is extended and easy to maintain It is about.

In general, the conventional artificial turf field is constructed by attaching a foam rubber pad of 10 to 12mm thick under the artificial turf planted with grass length of about 12.5mm and attaching it to the surface layer where civil engineering is completed. Since the width of artificial turf is about 2m, at least 50 artificial turf is laid when it is installed in 100m long ballpark, and the width joint of these artificial turf is connected with sewing machine. About 6 years, artificial turf degrades rapidly after about 5 years, resulting in the formation of bone joints with wide seams. In addition, foam rubber pads attached to the bottom of the artificial turf is hard to be used by athletes, since the resilience of elasticity starts to decrease after about 4 years and hardens to almost the same as concrete, which rapidly decreases after 5 to 6 years. There is a problem that there is a risk of injury, and the shrinkage rate of the artificial grass and the shrinkage rate of the foamed rubber pads are different from each other during the curing of the foamed rubber pads, so that the parts connected to the foamed rubber pads are separated by 1 to 3cm. As shown in Figure 4, the goal (S) is to be formed, there is a problem that can cause a serious phenomenon even to the safety problems of players because of the lack of performance during the game as well as falling. Moreover, when sand is filled on the conventional artificial turf, the foam pad of the conventional artificial turf must additionally support the weight of such filled sand or silica sand, so that the resilience of the artificial turf decreases rapidly. There has been a problem that the above-described problems such as shortening and generation of bone in the connection part occur more quickly.

The object of the present invention is to solve such a problem, the elasticity recovery of the shock absorbing layer is semi-permanently ensured to extend the life of the artificial turf and to form the shock absorbing layer continuously integrally, so that the width of the shock absorbing layer No goal is formed or there is no floor split, so it can be played safely. When reconstruction, only the artificial turf of the surface can be removed and new artificial turf can be replaced and used to reconstruct the air and construction cost inexpensively. Since the curved surface and the uneven part of the floor surface can be evenly constructed, the artificial turf structure of the artificial turf field can be reused by re-crushing the shock absorbing layer when the artificial turf field is dismantled.

This object of the present invention is to mix and agitate a plurality of chips broken into thin pieces of waste tires into a waste rubber adhesive, and then to a predetermined thickness on the surface layer of the ground construction layer, such as ready-mixed concrete, which is finished after the civil work of the ground surface layer is completed. It is achieved by the artificial turf structure of the artificial turf field according to the present invention, which is applied to form a waste rubber complete layer and the artificial rubber layer is cured and then the artificial turf is laid thereon and sand or silica sand is filled on the artificial turf.

With reference to the accompanying drawings, artificial turf structure of the artificial turf field according to the present invention will be clearly understood its features and advantages by the embodiments described in detail below.

1 is a partially cutaway perspective view of an artificial turf structure according to an embodiment of the present invention, FIG. 2 is a longitudinal cross-sectional view taken along line II of FIG. 1, FIG. 3 is an enlarged cross-sectional view of a portion B of FIG. 2, and FIG. 4 is a longitudinal sectional view of a conventional artificial turf structure.

As shown in the figure, the artificial turf structure (A) according to the first embodiment of the present invention is mixed with a plurality of waste rubber chips (2) crushed waste tires into an adhesive (3) and stirred and surface engineering works The surface layer of the ground construction layer (1) where there is no fear of ground subsidence is finished by spreading it to a certain thickness to form a hard rubber waste layer (4), and artificial grass (5) on the hardened waste rubber layer (4). ) Is disposed, and the filling layer 6 filled with sand at a predetermined height on the artificial turf 5 is formed. The ground works layer (1) is usually finished with a permeable concrete or asphalt concrete, or may be omitted in the concrete construction in places where there is no fear of ground subsidence. The thickness of the ground work layer in the sand-filled artificial turf field is preferably formed to be 20mm or more.

The waste rubber chip 2 used in the waste rubber layer 4 is crushed into a polyhedron having a minimum diameter of 0.5 mm or more and a maximum diameter of 7 mm or less, in which waste tires are irregularly carved. Since the waste rubber chip has excellent elastic restoring force and excellent durability, the waste rubber buffer layer 4 has a semi-permanent durability life. As the adhesive 3 used for the waste rubber buffer layer 4, an adhesive having excellent adhesion to rubber is used. As the thickness of the waste rubber buffer layer 4, the thickness of the artificial turf ball filled with sand is preferably about 15 mm or more, and of course, the thickness may be added or subtracted if necessary. Since the waste rubber buffer layer 4 is integrally poured over the entire area of the installation field, the waste rubber buffer layer 4 has the desired level of slope of the playground without any breaks, fines or irregularities. It became installable. That is, in the conventional artificial turf field, when the surface layer of the ground work layer 1 is incompletely constructed or there is a defect such as an uneven portion, the conventional artificial turf has a pre-made foam rubber pad attached to the bottom to correct such a defect. It can't be installed, so it's installed as-is. In addition, the waste rubber buffer layer (4) can be installed in the most suitable thickness in consideration of the purpose and purpose of the artificial turf field will be able to maintain the optimal state.

The artificial turf 5 is made of nylon or polypropylene yarn, the height of the grass is more than 25mm is suitable.

Filling height of the filling layer (6) filled in the artificial turf (5) is filled to about 90% of the length of the artificial turf, or football, baseball, rugby, tennis, etc., filling the silica sand to the end of the grass improves the performance When used as a hockey field, it is appropriate to fill up to about 80% of artificial turf length. In this embodiment, a single material such as sand or silica sand is used as the filler, but the rubber layer is laid at about 10% of the length of the artificial turf in the lower part of the filler layer 6 so as to prevent the filler from being cured when used for a long time. When formed of two layers filled with sand or silica sand thereon, even if the sand or silica sand is cured when used for a long time, the rubber chip in the filling layer gives elasticity, it is possible to give long-term elasticity to the artificial turf.

The artificial turf structure of the artificial turf field according to the present invention having such a structure forms a waste rubber buffer layer by using waste rubber chips that crush waste tires, so that resources can be recycled and the waste rubber buffer layer can be used at the construction site. Because it is formed to a certain thickness, it is formed as a single body because there is no joint part, so there is no fear of gap between the joint part due to the contraction of the elastic layer, so that the game can be safely and comfortably used. As there is almost no use, it can be used for a long time, and the service life is extended, and the surface of the waste rubber buffer layer can be formed to have an arbitrary slope when constructing the waste rubber buffer layer. You can do it. In addition, when the artificial turf is repaired, only the damaged artificial turf needs to be removed, and new grass is laid again, so that it is easy to maintain and can be maintained at low cost, and when the artificial turf is removed, the waste rubber buffer layer is removed and the waste rubber buffer layer is removed. Since the rubber chips constituting the separation can be installed again in another place, it has various excellent effects such as repeated use.
