Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface structure of a playground,

The present invention relates to a surface layer for a playground, and more particularly, to a surface layer composition of a playground having a clay layer such as a tennis court and a method for constructing a surface layer of a tennis court using the same.

Generally, the surface material used in a playground is made of various materials such as clay, keel, artificial turf, natural grass, and wood. Of these, the clay system is typically used for tennis courts by clay kotatsu. Most of these clay coats are used to contain sand in mud or loess. In special cases, lawns or chemical coats using polyurethane or polyurea are used. Recently developed methods have been used such as a method in which a dense woven wire mesh is installed at regular intervals from the ground.

However, in the case of a chemical coat, the force is exerted on the joints, muscles, and bones of the human body, so that the use of the chemical coat is limited, and the equipment cost is much used. In addition, in the case of the grass coat, it is difficult to manage it and it is difficult to use it unless it is a special case because it requires a lot of facility cost. On the other hand, the woven wire netting also requires a lot of installation cost, and there is a problem in that it is difficult to use since the frying phenomenon of the tennis ball is different from the general tennis court.

Therefore, clay coats are mainly used, and conventional clay coats are difficult to manage as compared with hard coats. The clay coat must be pressed periodically by the roller to maintain a flat surface and the water must remain constant. Also, there is a disadvantage that it is very troublesome to recover the damaged part.

In recent years, as interest in environmentally friendly products increases, the need for antibacterial and sterilizing the playgrounds such as clay coats is increasing. Particularly, since the surface layer of the playground is always exposed to the outside, various kinds of dirt can be mixed and sterilization and sterilization are important.

These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; may be "connected," "coupled," or "connected. &Quot;

The surface structure of a playground according to the present invention will be described first. Here, a playground refers to a general clay-type playground, which may include a tennis court, a warning track of a baseball field, a pitcher mound, and a foul area in addition to a general multipurpose playground. In this embodiment, the functional surface layer 50, the maintenance layer 30, and the massage layer 20 can be seen as a surface layer over a wide range.

Referring to FIG. 1, the structure of a playground to which the present invention is applied will be briefly described. The basic lower layer 10 corresponds to a portion already constructed of crushed stone and gravel layer. Thus, the material and thickness of the underlying layer 10 may vary, and the crushed stone and gravel layers are examples only.

A massage layer 20 is formed on the base lower layer 10. The massaging layer 20 forms approximately 100 mm to 150 mm, and is formed of masato. Masato is a weathered soil that can be made into granite as weathered soil. The masato can be produced by sieving a material containing no impurities or organic matter and adjusting the particle size. The massage layer 20 serves to improve water dropping and compaction. The massaging layer 20 is characterized by good surface drainage, easy construction, and low cost. The massage layer 20 may also be in a state where it has been already applied.

A maintenance layer 30 is formed on the upper side of the massage layer 20. The repair layer 30 is formed by crushing clay bricks, and further contains pyrophyllite, lime and loess. The maintenance layer 30 is for covering the upper part of a playground such as a clay coat, and has a thickness of about 50 mm to 80 mm. The maintenance layer 30 is a portion where substantial damage is substantially caused during use of a playground, and is a part where maintenance is mainly performed.

The constituent material of the protective layer 30 has 50 to 150 mesh particles. This is to increase the drainage property, but it is not necessarily limited thereto. In this embodiment, the conservative layer 30 is composed of 50 wt% of yellow clay, 40 wt% of clay bricks, 9 to 10 wt% of pyrophyllite and 0 to 1 wt% of lime. Clay brick is a red brick, which makes the color of the playground visible by the naked eye red. The clay bricks are used by crushing the existing red bricks or waste bricks.

Because of the nature of the material, the repair layer 30 can be easily distinguished from the masato constituting the massage layer 20 and can be easily separated from the massage layer 20. [ Accordingly, when the repair layer 30 is damaged, for example, when a part of the repair layer 30 is pierced or lost, the operator can easily repair the repair layer 30 by filling the components constituting the repair layer 30 have.

A functional surface layer 50 is formed on the protection layer 30. The functional surface layer 50 is intended to increase bactericidal and antibacterial properties of a playground, and forms a thin layer between about 3 mm and 10 mm. By constructing the functional surface layer 50, it is possible to obtain an effect of improving the functionality and environmental friendliness of the surface layer of the playground.

The mixture constituting the functional surface layer 50 includes mica, elvan, and dolomite. Preferably, the mica, elvan stone and dolomite constituting the functional surface layer 50 are composed of 10% by weight, 10% by weight and 80% by weight, respectively.

Here, the mica expresses the unique far infrared ray emissivity and the antibacterial and hygroscopic function of mica, and the elvan has an antibacterial effect and inhibits propagation and proliferation of pathogenic bacteria and fungi. Especially, the elvan stone absorbs harmful gas in the soil by its own adsorption power, neutralizes harmful components such as heavy metals, and improves soil quality. In addition, Dolomite imparts an antibacterial function to enhance the effect of the functional surface layer 50.

In the present invention, the mixture is mixed with the coating liquid in the form of powder and applied on the top of the maintenance layer 30 by spraying. After the mixture is applied, the coating penetrates naturally through the pores in the upper part of the repair layer 30, thereby improving the retention of the functional surface layer 50. [ As described above, since the repair layer 30 has 50 to 150 mesh particles, the penetration can be smoothly performed.

In this embodiment, the coating liquid is composed of water, and the coating liquid and the mixture are composed of 70% by weight and 30% by weight, respectively.

On the other hand, a drainage channel 25 filled with silica sand is formed on the massage layer 20 in contact with the treatment layer 30. The drainage channel (25) is a portion through which the storm water discharged downward through the maintenance layer (30) can be discharged. The drain channel 25 may extend along the upper portion of the massage layer 20 and extend to a drain port (not shown).

(Test Example)

The following test was performed on the functional surface layer (50) constituting the present invention. This test was conducted to evaluate the resistance of the test substance to fungi. The test conditions are as follows.

A sample comprising mica, elvan stone and dolomite, which are a mixture constituting the functional surface layer 50, was prepared in an amount of 10% by weight, 10% by weight and 80% by weight, respectively. Five kinds of fungus strains (Aspergillus brasiliensis, Penicillium pinophilum, Chaetomium globosum , Trichoderma virens, Aureobasidium pullulans) were applied.

The specimens were inoculated with a mixed spore suspension and incubated at 28 ~ 30 ℃ and 85% relative humidity for 4 weeks. The degree of fungi in the specimens was measured at 1 - week intervals and the results were evaluated.

Specifically, a functional surface layer (50) sample was placed on a nutrient-salts agar prepared beforehand, and a mixed spore suspension of five fungal strains was evenly sprayed on the sample and the medium. This was incubated for 4 weeks under the conditions described above, and the degree of growth was observed with a naked eye and a microscope at regular intervals.

Name of sample Number of samples = 3 One week after 2 weeks Three weeks Four weeks Functional superficial mixture X1 0 0 0 0 X2 0 0 0 0 X3 0 0 0 0

As shown in Table 1 above, no growth of fungi was observed in the samples for 1 week to 4 weeks after the test. Accordingly, the functionality of the surface layer of the playground, in particular, the sterilization and the antibacterial performance, can be improved by applying the functional marker constituting the present invention. 3 is a photograph of a sample used for testing the functional surface layer 50 constituting the present invention.

Name of sample Construction method One week after 2 weeks Three weeks Four weeks Functional superficial mixture Application 1 98% 98% 96% 95% Application 2 97% 97% 96% 96% Normal 94% 88% 82% 80%

As shown in Table 2, the degree of retention of the functional surface layer 50 was different according to the method of constructing the mixture constituting the functional surface layer 50. [ First, Coating 1 and Coating 2 show examples in which the mixture is applied to the coating liquid in powder form at different places in a playground and then sprayed on the top of the coating layer 30 by spraying. When the mixture was applied by spraying method, the functional surface layer (50) remained at 96% or more even after 4 weeks, but conversely, it fell to 80% in the case of general construction. For reference, in general construction, the mixture is simply sprayed on the top of the maintenance layer 30.

From the above results, it can be seen that when the mixture is applied in the form of a powder, the mixture penetrates naturally through the pores in the upper part of the repair layer 30 after the mixture is applied, thereby improving the retention of the functional surface layer 50. In addition, as described above, since the repair layer 30 has particles of 50 to 150 mesh, the penetration can be smoothly performed.

A method for constructing a surface layer of a playground using the surface structure of a playground according to the present invention will be described.

First, the base layer 10 and the massage layer 20 are formed. Of course, in the absence of the massage layer 20, it is possible to precede the massage layer 20 step of building the masato layer 20 on the lower part of the repair layer 30. If necessary, And a drainage channel 25 filled with silica sand is formed at an upper portion of the drainage pipe 20.

A maintenance layer 30 is formed at the upper part of the massage layer 20, in which a repair layer 30 is formed. The repair layer 30 includes crushed clay bricks, and pyrophyllite, lime and loess. As described above, the repairing layer 30 is for covering the upper part of a playground such as a clay coat, has a thickness of about 50 mm to 80 mm, and the constituent material of the repairing layer 30 has 50 to 150 mesh particles . This is to increase drainage. In this embodiment, the conservative layer 30 is composed of 50 wt% of yellow clay, 40 wt% of clay bricks, 9 to 10 wt% of pyrophyllite and 0 to 1 wt% of lime. Clay brick is a red brick, which makes the color of the playground visible by the naked eye red. The clay bricks are used by crushing the existing red bricks or waste bricks.

Subsequently, a surface layer step is formed in which the functional surface layer 50 is formed on the protection layer 30. The functional surface layer 50 is composed of a mixture containing mica, elvan stone and dolomite. In the surface layer step, the mixture of mica, elvan stone and dolomite constituting the functional surface layer 50 is mixed with the coating liquid in a powder form, To the upper surface of the control layer 30.

As described above, the mixture constituting the functional surface layer 50 includes mica, elvan stone and dolomite. Preferably, the mica, elvan stone and dolomite constituting the functional surface layer 50 are 10% by weight, 10% by weight, By weight and 80% by weight.

Here, the mica expresses the unique far infrared ray emissivity and the antibacterial and hygroscopic function of mica, and the elvan has an antibacterial effect and inhibits propagation and proliferation of pathogenic bacteria and fungi. Especially, the elvan stone absorbs harmful gas in the soil by its own adsorption power, neutralizes harmful components such as heavy metals, and improves soil quality. In addition, Dolomite imparts an antibacterial function to enhance the effect of the functional surface layer 50.

In the surface layer step, the mixture is mixed with the coating liquid in the form of powder and applied on the top of the maintenance layer 30 in a spray manner. After the mixture is applied, the coating penetrates naturally through the pores in the upper part of the repair layer 30, thereby improving the retention of the functional surface layer 50. [ As described above, since the repair layer 30 has 50 to 150 mesh particles, the penetration can be smoothly performed.

Then, the functional surface layer 50 may be applied again on the upper surface of the playground. For example, by constructing the functional surface layer 50 at a constant cycle, the antibacterial and sterilizing performance of a playground can be maintained at a high level. Of course, such an operation can be accomplished simply by applying a mixture constituting the functional surface layer 50.
