Abstract

The present invention relates to a shock absorption pad for a horizontal drainage type artificial turf. According to the present invention, the shock absorption pad comprises a rainwater guide groove including horizontal and vertical grooves, and a rainwater drain groove including left and right diagonal grooves such that a permeable hole perforated on an artificial turf matt on a site is not blocked, thereby smoothly realizing permeability when being constructed; water, such as flow-in rainwater, etc., naturally drained towards a side line and an end line of a stadium through the rainwater drain groove; and a connection part formed on an edge of the adjacent shock absorption pad and a bonding tape bonded on an upper surface thereof, thereby preventing a gap from being formed between the edges of the adjacent shock absorption pads and allowing the water such as flow-in rainwater, etc., to vertically penetrate the shock absorption pad, thus preventing the water from penetrating between a base layer and the shock absorption pad. Accordingly, a subsidence effect of the base layer and a blistering effect of the shock absorption pad are prevented to flatten the constructed artificial turf without being bent, thereby removing interference during a progress of a game.

Description

{Horizontal drainage type shockproof pad for artificial turf}

The present invention relates to an artificial lawn impact absorbing pad for a horizontally draining artificial lawn, and more particularly, to an artificial lawn artificial lawn which is constructed in such a manner that the artificial lawn is drained through a potion, It can be applied quickly and easily. It can be applied without being restricted by the kind of ground, and it can maintain a certain amount of water to prevent excessive rise of surface temperature in summer and increase durability of artificial turf. The present invention relates to an impact absorbing pad for a horizontal draining type artificial turf which does not cause any artificial turf to bend and maintains a flat state and maintains a shock absorbing property for protecting the athlete, .

Artificial turf system is composed of drainage board, shock absorbing pad, artificial turf mat, silica sand, elastic chip and so on to perform similar function to natural turf. Drain board is installed under artificial turf to facilitate water outflow, Therefore, the shock absorbing pad can not compensate the shock absorbing property which is the basic property of the artificial lawn system. The shock absorbing pad is developed to simply play the role of shock absorbing and is made by drilling the penetrating hole for a certain portion of the pitcher. Artificial turf mats are made by planting artificial turf files on the surface fibers called bubbles, coating them with a liquid back coat to prevent them from falling out, or by drying the artificial turf piles on other materials. In order to penetrate the pitcher holes at regular intervals. Silica sand is laid on artificial turf mat to form artificial turf files and stabilize artificial turf mats, and artificial turf fillers (elastic chips or functional chips) are installed to give artificial turf performance above a certain level to complete the artificial turf system .

 Generally, artificial turf for the athletic field is divided into a horizontal drain artificial turf system and a vertical permeable artificial turf system.

The horizontal draining artificial turf system is constructed by installing an impermeable base layer such as concrete or asphalt on the ground or a foundation layer having a very low permeability of 180 mm or less per hour and laying a drain pan or an impact absorbing pad on the base layer if necessary , Or a structure in which a functional chip such as an elastic chip is laid on the base layer or on a drain plate or horizontally drained on a layer of sand on a synthetic turf mat to drain into the sidewall.

Such horizontally drained artificial turf is such that the water such as rain water becomes high on the artificial turf mat and the silica sand or artificial turf filler (elastic chip or functional chip) is lost due to the drainage of excellent water, There is a problem.

On the other hand, the artificial turf of vertical permeability type is made of a porosity pipe in the ground, buried in a blind cement connected to a sidewall installed around the stadium, and a plurality of lower permeability holes perforated vertically so as to penetrate the vertical permeable shock absorbing pad , And a synthetic grassmat is applied to the surface of the ground, and the ground surface is made of silica sand alone or a synthetic grass filler (elastic chip or functional chip).

In this case, the impact absorbing pad can be manufactured by drilling a plurality of lower water holes in the manufacturing process. However, the artificial turf mat may be manufactured by arranging artificial turf files on the bubble paper and by removing the artificial turf pile Since the back coating agent is applied on the bottom surface, the upper penetrating hole is drilled using a nail or perforator heated to form an upper water hole in the manufacturing process.

Therefore, the shape and size of the lower penetrating pads of the shock absorbing pad are various and the intervals are various, and the upper water hole of the artificial turf mat does not coincide precisely. The upper surface of the impact absorbing pad and the lower surface of the artificial turf mat are normally flat The lower permeable hole punctured in the impact absorbing pad is blocked by the artificial turf mat, and the upper permeable hole punctured in the artificial turf mat is blocked by the impact absorbing pad, so that the permeability is lowered.

As a result, water, such as storm water, which has passed through the upper water hole, blocked by the impact absorbing pad among the upper water hole penetrated through the artificial turf mat, can not be drained through the lower water hole, The artificial turf can not be maintained flat due to a high rigidity on the top surface of the impact absorbing pad or the top surface of the artificial turf mat, resulting in bending, which hinders the progress of the game.

In order to simulate the performance of the natural turf, artificial turf filler (elastic chip or functional chip) is sprayed on the artificial turf mat. This sandpaper or artificial turf filler is introduced into the upper water hole and the lower water hole, And the above-described problems caused by the drainage not being smoothly performed are increased.

In addition, when the base layer is applied to a base layer of a marble or a crushed stone layer, water such as storm water permeable to the lower water hole pierced through the impact absorbing pad flows in a gap between the lower surface of the impact absorbing pad and the upper surface of the base layer. In this case, the artificial turf can not be maintained in a flat state, and the artificial turf is bent, thereby hindering the progress of the game.

In addition, the artificial turf of vertical permeable type can be applied to the foundation layer which is formed by compacting the ground because the water such as storm water should be collected through the artificial turf mat and the shock absorbing pad through the vertical passage and buried in the ground, but concrete or asphalt There is a problem in that it is not applicable to the base layer laid and to the permeable concrete or asphalt of 180 mm or less per hour.

In addition, since a plurality of rows of blind culverts are installed in the ground, they must be connected to a construction site around the stadium, so that construction is troublesome, construction is delayed, and construction cost is excessively increased.

Artificial turf piles are made of polyethylene (PE) material. This material tends to be soft and durable when holding a certain amount of water. In addition, artificial turf has a problem of excessive temperature rise in the summer, but if a certain amount of moisture is retained in the impact absorbing pad, a technique capable of preventing the temperature from rising while the stored water evaporates is required.

As a conventional prior art, there has been proposed a method of constructing an artificial turf using a drainage plate and a method of constructing an artificial lawn using a drainage plate according to Korean Utility Model Registration No. 10-0989938 (registered October 19, 2010) and Korean Utility Model Application 20-2011-0006041 (June 16, 2011) Artificial turf structure for soccer field "and Korean Patent No. 10-1676277 (registered on September 11, 2016)" Method for forming artificial turf field using elastic sand ".

Therefore, there is no water on the artificial turf due to excellent drainage, and artificial turf is kept flat without bending, so that it does not interfere with the progress of the game, and it is essential that the artificial turf is not buried in the ground, It is required to develop a technique capable of performing construction without any restriction on the type of ground and reducing the temperature rise of artificial turf.

The gap guide grooves 120 and the discharge grooves 130 may be simultaneously formed in the process of forming the pad body 110.

However, since the abdominal indentation groove 120 has a groove width of 1 mm and a depth of 0.5 to 1 mm, it can be simultaneously formed in the process of forming the pad body 110, Since the pad body 110 has a groove width of 10 mm and a depth of 5 to 10 mm, it is technically difficult to simultaneously form the pad body 110 in the process of forming the pad body 110, It is preferable to form it through a cutting process.

A calender cutter, a laser cutter, or the like may be used for the cutting process for forming the discharge grooves 130.

The storm relief groove 120 may include a lateral groove 121 parallel to the lateral side of the pad body 110 and a longitudinal groove 122 parallel to the longitudinal side of the pad body 110.

The horizontal grooves 121 and the vertical grooves 122 may be formed to have a spacing of 10 to 20 mm so that the square grooves are formed by the horizontal grooves 121 and the vertical grooves 122.

The overflow guide groove 120 may be formed in a " V "-shaped cross section, but it is preferably formed in a" V "

The storm drainage grooves 130 may be formed of a left and right grooves 131 and 132 intersecting the horizontal grooves 121 and the vertical grooves 122 at an angle of 45 degrees .

Since the upper discharge grooves 130 are formed by the left and right grooves 131 and 132 having the angle of 45 degrees, they are maintained at an angle of 45 degrees with respect to the side line and the end line of the playing field, The stadium is installed so as to have a downward sloping gradient? With respect to the horizontal line VL toward the side line and the end line with reference to the center line CL (see Fig. 3) Line and the end-line.

The artificial turf stadium is constructed by using the shock absorbing pad 100 described above by forming a foundation layer 200 on the ground and forming an opening 300 on the edge of the foundation layer 200, A plurality of impact absorbing pads 100 are installed on the base layer 200 and the nonwoven fabric 400 is impregnated with an adhesive on the impact absorbing pad 100 to form a double- The artificial turf mat 500 is placed on the nonwoven fabric 400 so that the artificial turf mat 500 is adhered to the impact absorbing pad 100 by the nonwoven fabric 400, A step of forming a silica sand layer 600 is performed.

The foundation layer 200 can be formed by flattening the ground or by laying concrete or asphalt.

When the artificial turf is formed using the impact absorbing pad 100, the artificial turf is formed as a horizontally drainage type by the storm drainage groove 120 formed in the pad body 110 and the storm drainage groove 130, It is possible to apply the present invention to both the water-permeable base layer and the non-water-permeable base layer.

The nonwoven fabric (400) is preferably made of a synthetic resin nonwoven fabric to prevent corruption.

The artificial turf mat 500 has a structure in which a pile yarn 520 is planted on a pile fabric 510 and an adhesive is applied between a pile fabric 510 and a lower end of the pile yarn 520, 510 are used. A plurality of water holes 530 are drilled by using a heated nail or a perforator before the water is poured.

The lateral grooves 121 and the vertical grooves 122 constituting the excellent guiding grooves 120 are respectively spaced by 10 to 20 mm and the grooves of the transverse grooves 121 and the vertical grooves 122 are formed to have a groove width of 1 mm When the inner diameter of the water hole 530 is 5 mm to 10 mm, the water hole 530 may be connected to either the horizontal groove 121 or the vertical groove 122, The transverse grooves 121 and the vertical grooves 122 constituting the transverse grooves 121 and 122 are connected to the exudent discharge grooves 130 so that permeability is not lowered.

The discharge outlet groove 130 is formed by the left and right slot 131 and the main slot 132 so that the water such as the inflowing rainwater flows smoothly and smoothly toward the side pot 300 provided along the side line and the end line. do.

Therefore, the artificial turf does not flood with excellent water, and the game progress will be prevented.

The silica sand layer 600 is formed by spraying silica sand on the base paper 510 to give a feeling of natural grass.

Meanwhile, when the artificial turf is constructed using the impact absorbing pad 100 according to the present invention, the impact absorbing pad 100 and the artificial turf mat are bonded by the nonwoven fabric impregnated with the laying adhesive, The artificial turf mat is separated from the impact absorbing pad 100 and the artificial turf mat is installed again. In this case, the wider the contact area between the upper surface of the impact absorbing pad 100 and the non-woven fabric, The artificial turf mat may be difficult to separate.

Therefore, in the present embodiment, the excellent storage groove 150 and the air layer forming protrusions (not shown) are formed at the center of the square surface portion 140 formed by the lateral grooves 121 and the vertical grooves 122 constituting the storm- When the artificial turf mat 500 is repaired or replaced after the installation by forming an air layer between the nonwoven fabric 400 adhered on the pad body 110 and the upper surface of the pad body 110, So that the mat 500 can be easily detached from the pad body 110.

In addition, the artificial turf mat 500 and the impact absorbing pad 100 are brought into close contact with each other by a compressive force acting on the artificial turf mad 500 and the impact absorbing pad 100, Even when the permeable hole 530 formed in the artificial turf mat 500 does not communicate with the superior guiding groove 120 or the discharging groove 130 due to the formation of the excellent storage groove 150, So that the pitcher hole 530 is not clogged.

In general, the surface temperature of artificial turf is increased to 70 to 80 ° C in the summer, and polyethylene, which is the material of the pile 520 of the artificial turf mat 500, does not exhibit optimal characteristics unless a certain amount of moisture is maintained. Because the athletes are easily injured by friction during the game, water is sprayed before the game to lower the surface temperature.

The superior storage groove 150 formed in the impact absorbing pad 100 according to the present embodiment fills a certain amount of moisture, so that the moisture gradually evaporates and the surface temperature is reduced, so that the lifting of the athlete can be prevented .

The air layer forming protrusion 160 may be formed to protrude higher than the surface portion 140, thereby sufficiently securing the air forming layer.

That is, the nonwoven fabric 400 in the form of a double-sided tape is adhered to the upper surface of the pad body 110 and is adhered to the lower surface of the base 510 of the artificial turf mat 500, An air layer is formed between the upper surface of the pad body 110 and the lower surface of the nonwoven fabric 400 by the upper storage groove 150 formed in the surface portion 140 and the air layer forming protrusion 160 The adhesion force between the pad body 110 and the nonwoven fabric 400 is lower than the adhesion force between the paperboard 510 and the nonwoven fabric 400 and the artificial turf mat 500 is lifted up, The artificial turf mat 500 can be easily separated from the impact absorbing pad 100 by separating from the pad body 110 while being adhered to the artificial turf mat 500. As a result, So that it can be done easily.

When a plurality of shock-absorbing pads 100 are laid in succession, a clearance is formed between the front, rear, left, and right ends of the adjacent shock-absorbing pad 100, The water such as drained water flows vertically through the gap between the edge of the adjacent shock-absorbing pad 100 and the shock-absorbing pad 100 and flows into the space between the base layer 200 and the shock-absorbing pad 100 As described above, causes the same problems as those in the prior art.

In order to prevent this, a connecting portion 170 is formed at the edge of the pad body 110 according to this embodiment to block the abdomen guiding groove 120 and the vent hole 130.

The connecting portion 170 is formed to have a thickness ranging from the lower surface of the pad body 110 to the surface portion 140. The adhesive tape 700 is formed on the upper surface of the connecting portion 170 of the adjacent shock absorbing pads 100, Absorbing pad 100 and the base layer 200 through the clearance between the edges of the adjacent shock-absorbing pads 100 through the permeable hole 530 of the artificial turf mat 500 In order to prevent it from being introduced into the space.

At this time, since the stadium is installed so as to have a slope downwardly inclined toward the side line and the end line (see Fig. 4) around the center line portion, the stadium having excellent permeability through the water hole 530 of the artificial turf mat 500 Water is introduced into the storm relief grooves 120 and then introduced into the storm drain grooves 130 and discharged therefrom. The edges of each of the shock absorbing pads 100 are formed with connecting portions 170, Since the discharge groove 130 is blocked, the water such as the abdomen flows over the connecting portion 170 and the adhesive tape 700 adhered to the abrasion pad 100, 130, and flows through the side line 300 along the side line and the end line of the stadium finally while repeating this process.

Therefore, the inflowing water such as rainwater does not flow between the impact absorbing pad 100 and the base layer 200, so that the settlement of the base layer 200 and the swelling of the impact absorbing pad 100 do not occur. As a result, Since artificial turf is kept flat without bending, it does not hinder the progress of the ground surface.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention.
