Elastic grass mat for artificial turf construction {AN ELASTIC MAT}

The present invention relates to an elastic mat for artificial turf construction, and more particularly, to provide an elastic mat improved to improve activity by reducing geothermal heat while evaporating in a state of containing moisture with excellent water permeability and ease of construction. It is about.

Artificial turf is used as a substitute for natural turf, which is cheaper in construction cost, but it is used in a lot of construction because it is relatively inexpensive to maintain and manage compared to natural grass, which has a high maintenance cost.

The artificial turf as described above is constructed almost as much as natural grass due to the development of technology, and it is a sports yard such as a playground, a school, a soccer field, a futsal stadium, a walkway or a park, as well as a yard or building of a house. It is being installed in various fields such as the roof garden.

Looking briefly at the construction structure of the artificial turf constructed as described above,

Turf piles planted in the base to keep the upright state while absorbing the impact of the user to the grass layer filled with silica sand and rubber chips to a certain height, and the elastic layer (pitcher concrete or pitcher asphalt) The secondary crushed stone layer, hereinafter referred to as permeable concrete) is formed to form a permeable layer, and a crushed stone layer is formed between the permeable layer and the ground.

Artificial grass to which the prior art as described above is applied to the permeable concrete (water permeable concrete, pitched ascon, waste tire chips, etc.) for the purpose of quickly absorbing and discharging moisture generated during rainfall and snowfall while absorbing shock. The construction cost is increased due to the difficulty of maintaining the entire large area flat because of the nature of the playground because it is constructed by placing and constructing the construction site on the whole construction area.

In particular, when the ground of any one site is settled in the process of use after construction, there is a problem that the settlement of the ground is settled continuously as well as the entire settlement area due to the nature of the whole connected by the pouring construction.

In addition, even if you want to repair the submerged site, it is not possible to repair it immediately after removing the submerged site, and it is difficult to repair after cutting a larger area than the submerged site, especially after repairing the existing construction of the cut surface. Due to the difference in the degree of compaction between the site and the repaired construction site, the same level cannot be maintained and a step is generated, which causes the secondary settlement.

In addition, the pores (pores) of the elastic layer are changed according to the conditions or the casting process of the site in which the elastic layer is placed, and thus the ability to discharge moisture is not uniform and variation occurs.

In this way, when the cabbage capacity of the elastic layer is different, the same vertical drainage is not achieved over the entire area, so that the water moves to the well-drained area during the rainfall and snowfall and drainage occurs.

As such, when the water moves in one direction and drained, the silica sand or the rubber chip constituting the grass layer moves together with the water, and after the drainage is completed, the artificial turf layer cannot perform the blast chamber.

In addition, since only the moisture is quickly discharged, when the outside air temperature is high, such as in summer, the area where artificial turf is constructed generates heat higher than other general grounds, causing heat island phenomenon and when contacting the body. There are many problems such as not being able to rule out the cause of the thermal injury, and in addition, the existing elastic layer is a waste that can not be recycled during partial repair or refurbishment.

Therefore, the present invention has been designed to solve the above problems, the crushed stone layer formed for drainage and load support on the ground, and the elastic layer to absorb the impact while preventing the water accumulation on the upper surface of the crushed stone layer, In the artificial turf formed on the upper surface of the elastic layer formed by forming a grass layer filled with silica sand and rubber chips so as to be able to absorb the impact while maintaining the grass pile and the grass pile upright state;

The elastic layer is an elastic mat body having a connecting means at the edge to be fitted to each other, a plurality of drain holes formed to penetrate in the thickness direction for water drainage on the elastic mat body, and the surface of the elastic mat body Consists of an elastic mat including a water-containing cup that stores a portion of the water drained in the water to evaporate to cool the heat generated on the surface of the artificial turf, thereby providing ease of construction and maintenance. It is characterized by reducing the surface temperature of artificial turf through vertical drainage and water function.

The present invention is composed of an elastic layer to be mated with the adjacent mat to provide ease of construction and maintenance, as well as vertical drainage to prevent the loss and movement of silica sand and rubber chips in the drainage process It is designed to have a variety of effects such as lowering the heat of the artificial turf layer to prevent heat island phenomenon and maintaining a comfortable use state, and recycling it.

Generally, the artificial turf 100 forms a crushed stone layer 102 on the ground 101 for drainage and load support, and prevents water from pooling on the surface of the artificial turf due to rainwater on the upper surface of the crushed stone layer 102. While forming the elastic layer 103 to absorb the impact.

On the upper surface of the elastic layer 103, so that the grass pile 105 and the grass pile 105 planted in the base 104 can maintain the upright state while absorbing the impact of the user's silica sand 106 and rubber The grass layer 108 is formed by filling the chip 107 to a certain height.

The present invention is characterized by improving the elastic layer 103 to the elastic mat 110 to prevent geothermal rise with a rapid vertical drainage and water function while providing ease of construction and maintenance.

The elastic mat 110 is provided with an elastic mat body 111 is provided in the shape of a square, rectangle, pentagon, hexagon, etc., and the elastic mat body 111 and the puzzle and adjacent to the edge of the elastic mat body 111 Make sure to have a connecting means to fit together.

The elastic mat body 111 is made of a material such as PU (urethane), PT, PP, PE, ABS, EVA of cross-linked foam, and a plurality of drain holes penetrating in the thickness direction of the elastic mat body 111 ( 112, 113) to induce vertical drainage so that water generated during rainfall and snowfall naturally flows to the ground.

A function of cooling the heat generated on the surface of the artificial turf 100 by forming evaporation cups 114 and 115 having a concave shape throughout the surface of the elastic mat body 111 to store and evaporate a part of the drained water. To reduce geothermal heat and eliminate heat islands.

The shape of the water cup (114, 115) may be configured in a variety of shapes, such as square (diamond), pentagon, hexagon, etc., the depth (D) of the water cup (114, 115) elastic mat body 111 so as not to interfere with the elasticity ) It is good to have a depth of 1/2 or less with respect to the total thickness (T).

In addition, it is preferable that the size of each of the water cups 114 and 115 is not formed so wide that the water cups 114 and 115 are not easily damaged by the conducted load in the process of using the artificial turf 100. The upper surface of the body 111 as well as the bottom may be formed in the same shape.

The height H of one of the horizontal walls 116 and the vertical walls 117 constituting the water cups 114 and 115 has a height H1 lower than that of the other walls 116 and 117. The water drained apart from the bottom of the base 104 of the layer 108 may be configured to have a water flow path 118 through which the water flows toward the adjacent drain holes 112 and 113.

Looking at the use of the artificial turf 100 construction elastic mat 110 to which the technique of the present invention is applied as described above are as follows.

The elastic mat 110 is connected to the upper surface of the crushed stone layer 102 constructed on the flatly ground ground 101 by connecting with the adjacent elastic mat 110 using a connecting means, such as puzzle fitting, and the elastic mat ( The grass layer 108 is constructed on the upper surface of the 110 to complete the artificial turf 100.

In the construction state as described above, the impact generated by the user walking or running the grass layer 108 is transmitted to the elastic mat 110 is absorbed, the moisture generated by the rain or snow is the grass layer 108 Through the elastic mat 110, the crushed stone layer 102 is drained to the ground (101) it is possible to prevent the phenomenon of water pooling on the surface of the grass layer (108).

In particular, in the process of draining water, since the vertical drainage is made from the grass layer 108 through the elastic mat 110, the phenomenon of silica sand or waste rubber chips forming the grass layer 108 may be prevented from moving to other places. There is no hassle of having to re-install silica sand or waste rubber chips after water discharge is completed.

Then, the water moved downward from the grass layer 108 is vertically drained to the crushed stone layer 102 through the drain holes 112 and 113 formed in the elastic mat body 111, and in the draining process of the elastic mat body 111 The water is temporarily stored in the water cups 114 and 115 further formed on the upper surface, and the remaining water is drained through the drain holes 112 and 113.

At this time, any one of the horizontal wall 116 or the vertical wall 117 constituting the water cup (114, 115) is formed to a lower height than the other wall flow path 118 that can move the water to the adjacent drain holes (112, 113). ), It is possible to provide the ease of drainage.

If there is no flow path 118, the base 104 constituting the grass layer 108 is in close contact with the upper surface of the elastic mat body 111, except that the water drain holes 112 and 113 are not formed. In position it is not easy to drain vertically.

The moisture stored in the plurality of water-containing cups 114 and 115 formed on the upper surface of the elastic mat body 111 is evaporated while the grass layer 108 is heated by sunlight, so that the surface temperature of the grass layer 108 is increased. It is possible to prevent the activity to enable a comfortable activity, it is possible to prevent the heat island phenomenon that the temperature of the site where the artificial turf 100 is constructed compared to the cut area.

In addition, the elastic mat 110 of the present invention can be finished by replacing only a new elastic mat 110 after quickly removing only the site where the abnormality occurs when the ground 101 is damaged or damage to the elastic mat 110, and the like. Not only does it provide ease of maintenance, but it is also possible to recycle it without generating waste even for overall renovation such as replacement of artificial turf or change of usage.
