Abstract

PURPOSE:To prevent the rolling characteristic of a ball from being changed without fatigue feeling for game players even if the same place is used for a long time. CONSTITUTION:Fillers 6 are filled up so that the layer thickness may be 6mm or more at least, and yarn pieces 4 are erected on a lining base cloth sheet 5 so that the leaf tips may be projected by 6mm or more at least from the surface of a filling layer 7. Accordingly, by the weight of the fillers 6, on a substrate 1, laying work can be executed, and by the water-absorbing effect of the fillers, the water content of the leaf tips of the yarn pieces 4 is absorbed, and so water discharging property can be retained in. Besides, the upper surface of the filling layer 7 is to be covered with the yarn pieces 4, and even if sliding is performed by game players, frictional damage can be prevented from being generated, and a ball is also rolled at the leaf tips, and so the time passage change of the rolling of the ball in a hockey game can be made less.

2. Description of the Related Art In all-weather stadiums for ball sports such as tennis, baseball, soccer, and hockey, and in grounds, parks, plazas, etc., a synthetic resin yarn such as nylon or polypropylene is densely packed as a base material for the surface material. Artificial lawn planted in (in the following, referred to as sandless artificial lawn) or artificial lawn in which the spacing between the yarns is made slightly wider and a filling material such as sand is put in the grass grain (hereinafter referred to as sand-containing artificial lawn). ) Is widely used.

A sandless artificial lawn has a base cloth with a length of 6 to 14
The densely planted mm mm yarns do not impair the cushioning characteristics even after long-term use, the rolling performance of the ball does not change over time, and scratches can occur even if a player falls. Although it has the advantage of not being present, it is slippery and, when sliding, may cause burns due to friction with the surface yarn. In addition, in the case of a baseball game where metal spike shoes are used, the artificial lawn is damaged and the use of metal spike shoes must be restricted. Further, since the yarn and the base cloth are only used, the cushioning property at the time of landing of the athlete is hard, and the player feels fatigue when playing for a long time. In order to improve this, it is also proposed to arrange a cushioning layer composed of rubber chips or urethane resin chips on the bottom surface of the base cloth, but this is a local deformation that only the landing point of the athlete is deformed, and the feeling of fatigue. The current situation is that it has not been completely improved.

On the other hand, the artificial lawn containing sand is filled with a filling material such as sand or silica sand having a fine particle diameter so that the layer thickness is 13 to 30 mm.
-5 mm is projected. Therefore, moisture such as rain or water sprinkling is sucked into the packed bed, and the water drainage of the yarn is much better than that of the sandless artificial lawn, and the weight of the yarn is small. In addition, since sandless artificial grass has a light weight, it is fixed to the base by adhesion, etc.
Since it is 0 to 30 kg / square m, it can be laid on a base and can be constructed at an advantage that the construction cost can be reduced. Furthermore, since the filler layer is also exposed to some extent, burns due to yarn during sliding can be prevented, and when the athlete lands, the filler layer changes to a plate-like shape and has a surface cushioning effect, so there is no sand. It has better cushioning properties than artificial grass. For these reasons, athletic stadiums with artificial grass containing sand are becoming widespread.

However, the artificial grass containing sand has a drawback that scratches are liable to be caused by the filler exposed on the surface when sliding, and the filling layer is cured due to aging and the buffering property is further deteriorated. May deteriorate or may be locked up by accelerating metal spikes in the hardened packed bed. In addition, while ball games such as tennis that handle bouncing balls are not so affected, in the case of ball games that handle rolling balls such as soccer, hockey or rugby, the balls roll faster when the filling layer hardens due to aging. It was pointed out that the athlete could easily get scratched by a tackle, etc., and was considered unsuitable for such a ball game.

When the layer thickness of the filling material is at least 6 mm, the weight of the filling material increases or decreases depending on the type of the filling material. The construction cost can be reduced. Also, since the water absorption effect of the packed bed absorbs the water on the leaf tips of the artificial lawn, it can have the same drainage properties as conventional sand-containing artificial lawns, and can also be used for outdoor stadiums. On the other hand, the leaf tips of the artificial lawn are 6
By protruding more than mm, the surface of the filling layer will be covered with the leaf tips, and even if the athlete slides, it is possible to prevent the occurrence of scratches due to the filling material, and the filling layer is cured due to aging. However, the upper surface of the ball is covered with leaf tips and the balls roll on the tip of the leaf tips.Therefore, there is little change over time in ball rolling during hockey competitions, etc. You can also play ball games such as soccer. Furthermore, even if metal spikes are used, the protruding leaf tips serve as a cushion layer, and the amount of spikes entering the filling layer is reduced by that much,
It is possible to prevent the spikes from being trapped by the cured filling layer.

First, the first embodiment shown in FIG. 1 will be described. An artificial lawn 3 is laid via a cushioning material 2 on a base 1 whose upper surface is substantially smooth. The base 1 may have a water-permeable structure such as cobblestone or crushed stone, or a non-water-permeable structure such as concrete or asphalt.
The cushioning material 2 is laid on the base 1 by placing a foamed material such as a rubber chip or urethane or polyethylene at a construction site, or laying flat molded products. The artificial grass 3
Flat straight bristle split yarns or monofilament yarns 4 made of synthetic resin such as polyamide, acrylic, vinylidene chloride or polypropylene are lined with backing base fabric 5 by tufting, etc., and the same spacing as conventional sand-containing artificial lawns. It is constructed by planting a large number of plants. In this embodiment, each yarn 4 is composed of straight bristles, and is set to have a length sufficient to project from the backing base fabric 5 by at least 12 mm or more. The turf of the artificial lawn 3 is filled with a filler 6 made of sand having a fine particle diameter, silica sand, elastic granular material of polymer material, or a mixture thereof as the sand. The layer thickness of the filling layer 7 is set to be at least 6 mm or more from the upper surface of the backing base cloth 5, and 6 mm or more from the upper surface of the filling layer 7 to the tip of each yarn 4.

By setting the layer thickness of the packing layer 7 to be at least 6 mm, when the packing is silica sand, the weight of the sand is about 8.
Since the weight becomes kg / square meter and the artificial lawn 3 is laid on the base 1, the construction cost can be reduced. Further, the surface load characteristics are generated by the filling layer 7, and the synergistic effect with the cushioning material 2 in the lower layer can improve the feeling of landing when the athlete lands. Furthermore, since the layer of the filling material 6 has a water absorbing effect, it absorbs the moisture adhering to the yarn 4, so that it can also be drained and can be used in an outdoor sports field. On the other hand, the surface of the filling material layer 7 is covered with the leaf tips by protruding the yarn 4 which is the leaf tip of the artificial lawn 3 from the surface of the filling layer 7 by 6 mm or more. Can also prevent the occurrence of scratches due to the filling,
Also, even if the filling layer hardens due to aging, the upper surface will be covered with leaf tips and the balls will also roll on the leaf tips.
It is possible to perform ball games such as hockey and soccer, which have been considered unsuitable for sand-filled artificial lawns because the changes over time in ball rolling during hockey competitions are small. In addition, the yarn 4 protruding from the filling layer 7 serves as a cushion layer, and the amount of spikes entering the filling layer 7 is correspondingly small, so that the spikes are hard to lock.

Next, the artificial lawn yarn 4 was constructed with a pile of 10,000 denier polypropylene split yarn, the pile length was 25 mm, and the basis weight of the pile was 1400 g / square meter, and tufting was performed on the base cloth 5. On the lower surface of the base cloth 5, a cushioning material 2 composed of rubber chips was formed with a layer thickness of 10 mm to form a cushioning layer. The results are shown in Table 1.

As a result, it was found that when the exposure amount was 5 mm or less, the characteristics were almost the same as those of the conventional sand-containing artificial grass, but by exposing the pile of 6 mm or more, the characteristics were substantially the same as those of the artificial grass without sand. It was On the other hand, it was found that if the filling layer has a thickness of 6 mm or more, it can have its own weight that can be laid. The artificial grass used in this experiment has a basis weight of 1400 g / square meter
It can be seen that this is the same as (or approximately the same as) the basis weight of the artificial sand-containing lawn of the related art, and much smaller than the basis weight of the artificial lawn without sand.

As described above, in the athletic stadium made of artificial lawn of the present invention, the filling is filled so that the layer thickness is at least 6 mm or more, and the leaf tip of the artificial lawn is from the layer surface of the filling. Since it is planted in the base cloth so as to project at least 6 mm or more, the weight of the filling material becomes about 8 kg / square meter, and the weight is such that it can be laid on the base and the construction cost can be reduced. You can Also, since the water absorption effect of the packed bed absorbs the water on the leaf tips of the artificial lawn, it is possible to give the same drainage performance as the conventional artificial lawn with sand,
It can also be used for outdoor stadiums. Furthermore, by making the leaf tips of the artificial lawn project 6 mm or more from the surface of the filling layer, the top surface of the filling layer is covered with the leaf tips, and even if the athlete slides, the occurrence of scratches due to the filling material is prevented. Also, even if the filling layer hardens due to aging, the upper surface will be covered with the leaf tip and the ball will also roll on the leaf tip. However, it is possible to provide an athletic stadium that is optimal for such ball games.
