Description

The all-weather hard court}

The present invention relates to an all-weather multi-hard court, and if described in more detail, a uniform pavement of artificial turf on the existing asphalt concrete or urethane, concrete floor for sports infrastructure and paved floors such as school playgrounds, tennis courts, soccer fields, baseball fields, and trails. It relates to an all-weather multi-hard coat developed in order to have a uniform elasticity and excellent drainage capacity while being easy to construct and to escape from the artificial method.

The origin of most athletic activities, including athletics, originated from the ground, except for some, and is divided into two categories, such as basketball and volleyball, moving indoors and taking place on the indoor floor, and still taking place on the ground, such as tennis and baseball.

In the past, the ground was simply flattened, stones were removed, soil or sand was inserted, and flattened. However, when it rained, drainage was not done quickly, making it impossible to play the game due to strong softness, and dust generated during drought and pressure (hardening). In the case of a fall, there is a high risk of injury, and in the case of ball games, there are disadvantages such as not being able to make a certain bound on the ground.

Therefore, natural or artificial turf is planted for various purposes such as protection and convenience of athletes not only in the stadium but also in the school playground, and a layer of various natural or artificial compositions is formed on the existing ground to facilitate drainage and give a little elasticity. In the case of the event, the accuracy of the game and the reduction of injuries to the players are being made.

However, natural turf has the disadvantage of having to perform strict management and maintenance continuously.Although artificial turf is relatively inexpensive, there are concerns about injury due to friction and ingredients other than natural materials may cause atopic dermatitis, especially due to lack of durability. There was a problem of early departure from the purpose.

On the other hand, when delicate bounds such as tennis and basketball are maintained to protect the players and to play a stable game, a layer of various materials is formed on the ground, and finally, natural soil is used or a polymer compound such as polyurethane or acrylic resin is used. A finishing hard coat is being built.

However, in the case of natural soil, it is affected by the climate and has to be continuously supplemented and managed, so it is expensive and has a disadvantage in that the number of days used is limited. Due to moisture, cracks, surface peeling, and swelling occur, which interferes with the game due to irregular bounds in which the ball's bounds are irregular, and the moist surface becomes slippery, exposing the risk of injury, and durability. There are drawbacks.

Korean Patent Registration No. 10-0599840-0000 (July 5, 2006) Korean Patent Registration No. 10-0714750-0000 (April 27, 2007) Korean Patent Registration No. 10-1665496-0000 (October 6, 2016) Korean Patent Registration No. 10-1762172-0000 (July 21, 2017)

In addition, the surface finish layer is characterized in that perforation is formed with 3 to 7 vertically penetrating capillaries having a diameter of 1 to 2 mm per unit area of 100 * 100 mm.

In addition, the surface finishing layer is made by mixing 75 to 90% by weight of acrylic, 8 to 20% by weight of antoca of 0.5 to 1mm, and 1 to 5% by weight of silica sand;

The microfiber layer is 90 to 99% by weight of soil adjusted to have a particle size of 0.001 to 2 mm after firing natural soil at high temperature, and 1 to 10% by weight of microfibers with a thickness of 0.1 to 0.5 denier and a length of 5 to 20 mm It is characterized by adding and mixing.

In addition, along the rim on which the hard coat is formed, one side is in close contact with the base layer, the upper part is in close contact with the intermediate layer, and an eco-friendly natural turf permeable side canal in which a number of perforated holes are formed is embedded in the outer surface.

In addition, in the original ground of the hard coat, drainage grooves that increase in depth from the center to the edge are formed in front and rear and left and right, extending to a drain pipe path formed on an edge spaced apart from the original ground on which the hard coat is formed, and 25 It is characterized in that a drainage aggregate layer formed by inputting ~ 50mm of mixed aggregate is formed.

Accordingly, the configuration of the present invention will be described in detail so that those skilled in the art can easily understand and reproduce it by the accompanying drawings.

1 is a conceptual diagram according to an embodiment of the present invention, and relates to an all-weather multi-hard coat 1 formed by forming five or more layers on top of a base material 11 on which a compaction operation and a planarization operation are performed.

The present application stabilizes the ground and facilitates drainage by inputting the mixed aggregate to the top of the original ground 11 on which the compaction and flattening work is completed to form an auxiliary base layer 12 formed to a thickness of 50 to 80 mm, Capillary fringe water is filled in the small pores between the particles to preserve a certain amount of water.

In addition, the sub-base layer 12 is made of permeable ascon or concrete to have a thickness of 50 to 120 mm, and a base layer 13 forming a nonwoven fabric layer 131 is constructed on the upper surface, and permeable ascon or concrete (Hwangpo Pavement) is often constructed on a bicycle road or playground, which increases durability to maintain a flattened state constructed through the construction of the base layer 13, and at the same time has a structure that facilitates drainage.

When the intermediate layer 14 is formed with a thickness of 15 ~ 25mm made of cork on the upper surface of the base layer 13, the pitcher is easily made, and the elasticity of the cork prevents the impact transmitted to the legs and knees of the exercising person. In the ball game event, when the ball is bound, it does not slip and a certain bound occurs, thereby improving performance and preventing injury.

In addition, when the upper surface of the intermediate layer 14 is formed by mixing acrylic resin, Antoka and silica to have a thickness of 4.5 to 10 mm, and forming a surface finishing layer 15 formed by covering with a microfiber layer 151 on the upper surface, a microfiber layer ( 151) helps to function as a clay coat while preventing the loss of acrylic resin, antoine and silica.

At this time, the surface finish layer 15 is made by mixing 75 to 90% by weight of acrylic, 8 to 20% by weight of antoca of 0.5 to 1mm, and 1 to 5% by weight of silica;

The microfiber layer 151 includes 90 to 99% by weight of soil adjusted to have a particle size of 0.001 to 2 mm after firing natural soil at high temperature, and microfibers 1 to 1 to 20 mm in length and 0.1 to 0.5 denier in thickness. An example made by adding and mixing 10% by weight was further presented.

When the microfiber layer 151 is formed on the surface, it has the same effect as that of the cray coat, and the shear strength by the microfiber increases, thereby increasing durability, and improving moisturizing and drainage capabilities.

At this time, the present invention presented an embodiment characterized in that the surface finish layer 15 has 3 to 7 vertically penetrated capillaries 152 having a diameter of 1 to 2 mm per unit area of 100 * 100 mm are formed perforation.

The capillary tube 152 prevents excessive drying of the bottom surface because the water content of the lower intermediate layer 14 can move upward, and water is discharged to the bottom more quickly through the capillary tube 152 in rainy weather.

In addition, the upper hole for forming the capillary tube 152 increases the frictional coefficient of the surface, thereby helping to generate the aforementioned constant bound.

In other words, this structure of the present invention maintains a certain degree of moisture content in the interior during normal times to prevent excessive drying of the upper surface, while allowing rapid and smooth drainage when the inflow of water increases due to rain, etc. It will be possible to replace the facility with artificial turf.

In addition, the process consisting of sequential lamination and flattening is easy to construct, reducing construction costs, and minimizing loss from the surface to facilitate maintenance.

Figure 2 is a cross-sectional view according to another embodiment of the present invention, along the rim on which the hard coat 1 is formed, one side is in close contact with the base layer 13, the upper side is in close contact with the intermediate layer 14, and a plurality of perforations are penetrated on the outer surface. An embodiment characterized in that the side channel 16 in which the hole is formed is buried.

In rainy conditions that occur during all competitions, it is one of the most important factors in early resolution of the drainage problem, which prevents the formation of puddles on the ground, so that the schedule is not disrupted to proceed if there are no major obstacles or risk factors in the game. It can be said.

Therefore, rainwater paths are formed along the edge of the stadium to allow water to flow. However, in the case of rainwater paths, only the water on the surface flows in, and when water at a point far from the stormwater path exceeds the limit of the absorption and drainage capacity of the ground, It will stagnate or flow and interfere with the game.

The present application allows water that has flowed into the middle layer 14 and the base layer 13 as well as the upper side to be discharged through the side channel 16, so that particles other than water do not permeate through the permeable hole of the side channel 16. It is preferable that the side channel 16 is wrapped with a nonwoven fabric so as to be constructed.

3 is a conceptual diagram showing a process of forming a raw ground and a drainage aggregate layer according to another embodiment of the present invention, and FIG. 4 is a conceptual diagram according to another embodiment of the present invention, and the original ground 11 of the hard coat 1 Drainage grooves 111 that increase in depth from the center to the edge are formed in front and rear and left and right, and extend to a drainage pipe 17 formed on a border spaced apart from the original base 11 on which the hard coat 1 is formed, An embodiment characterized in that a drainage aggregate layer 171 formed by inputting a mixed aggregate of 25 to 50mm is formed in the drainage groove 111 is shown.

In case of rain, water penetrates into the lower part and all directions to prevent water from accumulating in the upper part, but if it exceeds its own drainage capacity, a separate drainage facility is required.

In the above embodiment, when the drainage pipe 17 formed on the edge spaced apart from the original ground 11 on which the hard coat 1 is formed is formed, water that cannot penetrate into the original ground 11 is spread and flows into the drainage pipe 17. At this time, the drainage pipe 17 has a shape in which a hole is perforated so that water can flow into the side or top, and is wrapped with a mesh net or nonwoven fabric.

In this case, when the drainage capacity of this structure is exceeded, the present application forms a drainage aggregate layer 171 that facilitates the flow of water because the pores are formed larger.

In the case of such a drainage aggregate layer 171, it may be formed in a structure that extends back and forth, left and right as shown, and when the size of the hard coat 1 is large, it is desirable to form a checkerboard arrangement to improve the drainage capacity. It is preferable to form the drainage groove 111 of the same depth without the difference in depth.
