Two slit grooves 12 are formed.

Here, the second slit groove 12 functions to prevent the coupling piece P from protruding to the surface of the line body 10 as well as to prevent slipping.

At this time, the coupling piece (P) is fixed in the ground to a relatively longer length than the first wing portion 20, and functions to prevent the line belt 100 from being twisted or moved on the ground.

The first wing portion 20 extends downward on both sides of the line body portion 10 and is embedded and fixed in the ground.

At this time, a hook projection (H) is further formed on the free end and the inner wall surface of the first wing portion 20 to prevent departure from the underground while facilitating entry into the underground.

In addition, the line body portion 10 is further formed with a plurality of drainage lines 13a that are formed through the first slit groove 11 and the second slit groove 12 in the width direction to intersect.

The drain line (13a) functions to drain the rainwater accumulated in the first slit groove (11) and the second slit groove (12) to prevent slipping.

On the other hand, the edge of the line body portion 10 and the first wing portion 20 facing each other is also further formed with a drain hole 14 for draining rainwater to the inside.

The drain hole 14 is designed to prevent a water film phenomenon occurring in the drain line 13a, and is connected to the drain line 13a to communicate with each other.

That is, the drainage line 13a can prevent the water film phenomenon caused by the surface tension of rainwater by communicating with the drainage hole 14 formed in the shape of “┏” or “┓.

[Second embodiment]

3 is a perspective view showing a line belt for a clay coat according to a second embodiment of the present invention, FIG. 4 is a cross-sectional view taken along the line B-B' of FIG. 3, and FIG. 5 is a line for a clay coat of the second embodiment. It is a perspective view showing a state in which the belt and the line belt are connected, and FIG. 6 is a cross-sectional view showing a state in which the line belt for clay coat and the line belt are connected in FIG. 5 .

3 to 6 , the line body portion 10 of the second embodiment has a third slit groove ( 13b) is formed.

In addition, the drain hole 14 is penetrated in the shape of "┏" or "┓" so as to partially invade the outer shell of the third slit groove 13b and the upper portion of the first wing 20, and the third slit It functions to drain not only rainwater accumulated in the groove 13b, but also rainwater accumulated on the ground together with the first and second slit grooves 11 and 12 communicating with the third slit groove 13b.

Therefore, the drain hole 14 also serves as an additional function of removing the rainwater accumulated in the first and second slit grooves 11 and 12, thereby preventing the sliding phenomenon due to the water film phenomenon.

In addition, the third slit groove 13b is configured such that an inclined surface 131 whose height is gradually lowered from the center of the line body 10 toward the outer shell is formed to guide rainwater to the drain hole 14 .

And on the bottom surface of the line body portion 10, the second wing portion 30 extends downward relatively longer than the first wing portion 20.

This second wing portion 30 is buried in the ground in two stages through a height difference different from that of the first wing portion 20, so there is no need for a separate fixing pin, and the line belt 100 is moved or seated on the ground. It is possible to prevent the detachment of the line belt 100 as well as to increase the overall rigidity of the line belt 100 .

Here, of course, a plurality of hook protrusions (H) may be formed along the free end and the inner wall surface of the second wing portion 30 as well.

On the other hand, between the first wing part 20 and the second wing part 30, with reinforcement, a transverse partition plate ( 40) is further connected.

This transverse diaphragm 40 connects the first wing part 20 and the second wing part 30 to each other to reinforce the first and second wing parts 20 and 30 entering the ground to prevent bending. It can serve as a primary function and a secondary function of forming a conduit 41 for accommodating rainwater falling through the drain hole 14 and discharging it to the outside.

In addition, the diaphragm 40 may serve as an additional function of preventing damage to external shocks by allowing the edge of the line belt 100 to be reinforced through the formed water channel 41 .

On the other hand, the rainwater accommodated in the water channel 41 communicates with the drain pipe 5 buried in the ground to prevent rainwater from leaking to the ground of the clay coat, and also the ground subsidence of the line belt 100 fixed to the ground and It is possible to provide a structure capable of preventing the line belt 100 from being twisted or displaced by preventing settling.

In addition, each of the second wing parts 30 may further include a protruding plate part 31 for mounting a connecting plate 32 interposed to connect the line belt 100 and the line belt 100 . .

Here, the protrusion plate part 31 functions to provide an insertion space between the line body part 10 and the line body part 10 for inserting the connection plate 32 .

Therefore, the connecting plate 32 is in close contact with the lower portion of the line body portion 10 through the protruding plate portion 31, as shown in FIG. 4, so that the coupling piece P fastened to the second slit groove 12 is It is fixed to the connecting plate 32 so that the two line belts 100 can be connected to each other.

In addition, since the connecting plate 32 is coupled in half between the two line belts 100 as shown in FIG. 3 , it can serve as an additional function of easily aligning the horizontal level of the two line belts 100 through this. .

7 is a cross-sectional view showing the structure of the clay coat surface layer to which the line belt for clay coat according to the present invention is applied.

The lower layer (1), the massage layer (2), the repair layer (3), the dressing layer (4), and the surface layer (5) are sequentially stacked, and the repair layer (3), the dressing layer (4) and the surface layer (5) A line belt for clay courts can be installed on the surface of the playground through

In the present invention, the installed clay coat line belt is hardly distorted by the use of the playground, and the soil constituting the playground exhibits antibacterial and sterilizing effects by containing jade powder in the surface layer.

To this end, by optimizing the components and contents of the repair layer 3, the dressing layer 4, and the surface layer 5 forming the surface layer structure, a surface layer structure suitable for a clay court playground where a line belt is installed is constructed.

To this end, the water retention layer and the surface layer use a composition comprising 20 to 40 parts by weight of pozzolan, 5 to 15 parts by weight of jade powder, and 40 to 60 parts by weight of loess, and the dressing layer contains pozzolan and jade powder at 6:4 to 4 By using a composition mixed in a weight ratio of :6, each physical property is optimized.

In addition, in the case of the clay coat, 5 to 15 parts by weight of the clay brick powder may be additionally included in the repair layer and the surface layer, and it is preferable to form each layer with a composition that does not use the clay brick powder in places such as a school playground. If the clay brick component is contained, there is a problem that the user's clothes get red, so it is preferable not to use it for purposes other than clay coats.

The water-retaining layer, the dressing layer, and the surface layer contain jade powder to enhance the antibacterial and sterilizing effect. In the prior art Korean Patent No. 10-1746550, mica, elvan stone, and dolomite are contained in the surface layer, and the mica exhibits far-infrared radiation, antibacterial and moisture absorption functions, and the elvan stone reproduces pathogenic bacteria and fungi through antibacterial effect. And it suppresses proliferation, and elvan has its own adsorption power to adsorb harmful gases in the soil, and it is described that it plays a role in improving soil quality by neutralizing harmful components such as heavy metals.

In the present invention, the antibacterial performance is further improved by using jade powder instead of the mineral powder such as mica, elvan, and dolomite. In addition, by containing the pozzolan powder pulverized to 3 mm or less, the problem of surface soil clogging drains in a rainfall environment or the problem of fine powder scattering in dry weather is solved. In addition, by optimizing the size of the particles and the thickness of each layer, it is possible to exhibit a stable surface layer structure and the characteristics of fixing the line belt installed in the playground through this.

The composition constituting the surface layer is preferably used by mixing and pulverizing each component so that the particle size becomes 50 to 100 mesh. In addition, it is preferable to use the water-retaining layer by pulverizing the particles to a size of 100 to 200 mesh.

Since the dressing layer is formed using a composition of pozzolan and jade powder pulverized to 2 to 3 mm before applying the surface layer after applying the water retention layer, it is possible to maintain good water permeability, and maintain temperature and humidity in the winter season And it is possible to maintain a limited surface layer structure even in summer. In addition, since the dressing layer does not contain loess, water permeability is improved so that moisture can easily permeate from the surface layer.

When laminating each layer using this composition, the massage layer has a thickness of 100 to 120 mm, the repair layer has a thickness of 80 to 100 mm, the dressing layer has a thickness of 2 to 3 mm, and the surface layer has a thickness to be 5 to 15 mm. When a line belt is installed in such a laminated structure, the line belt is inserted and fixed through the repair layer, the dressing layer, and the surface layer to the massage layer. Due to this installation structure, since the line belt is firmly fixed to the surface layer structure, distortion is greatly reduced, unlike the conventional line belt, so that the lifespan of the playground can be extended. In particular, on a surface to which various pressures are applied, such as a clay coat, the laminated structure is not only stable, but also exhibits antibacterial and sterilizing effects, thereby reducing harmful substances or bacteria that may occur in the playground.

The lamination method for forming the surface layer structure is to laminate the composition for forming the repair layer 3 on the massage layer 2 to a desired thickness, laminate the dressing layer 4 thereon, and finally the surface layer 5 ) is laminated to the desired thickness. Since the thickness may change due to pressure after lamination, the composition may be mixed with water and applied by spraying it when laminating, or applied in powder form and then compacted using a roller to laminate to a desired thickness. . In addition, in the case of spraying by a spray method, 30 to 40 parts by weight of the composition and 60 to 70 parts by weight of water may be mixed and sprayed in the form of a slurry.

In addition, a layer filled with silica sand may be formed between the sand layer 2 and the repair layer 3 , and a drain pipe 6 may be formed in the silica sand layer. The drain pipe 6 may be configured to allow moisture flowing down through the water retention layer 3 and the line belt to be discharged, and to extend along the top of the massage layer 2 to be connected to a drain.

As an example, the line belt was installed in a clay court tennis court equipped with the surface layer structure of the playground, and a test evaluation was performed. The surface layer structure of the example was installed so as to have a thickness of 110 ± 5 mm of the rubbing layer, 90 ± 5 mm of the water retention layer, and 10 ± 5 mm of the surface layer. In addition, as a comparative example, the surface layer structure of the playground according to Korean Patent Publication No. 10-1746550 was installed and the line belt was installed. In the comparative example, the surface layer structure was installed so as to have a thickness of 120 ± 5 mm for the masa layer, 70 ± 5 mm for the repair layer, and 5 ± 2 mm for the surface layer.

For each surface layer structure, the water retention layer and the surface layer were extracted to an area of 5 × 5 cm, and a mixed spore suspension of 5 fungal strains (Aspergillus brasiliensis, Penicillium pinophilum, Chaetomium globosum, Trichoderma virens, Aureobasidium pullulans) was inoculated into the specimen, and 28 to It was cultured for 4 weeks at 30° C. and 85% or more of relative humidity, and the degree of growth of mold in the specimen was observed at intervals of 1 week and the results were evaluated.

As a result, in Comparative Example, as in Korean Patent No. 10-1746550, no growth of mold was observed in the sample for 1 to 4 weeks, and the same results were obtained in Examples. However, as a result of operating the clay court tennis court for 6 months, no fungal strain was found when observed with a microscope in the Example, but some fungal strains were found in the comparative example, so that the surface layer structure of the example is antibacterial compared to the surface layer structure of the comparative example was judged to be somewhat better.

In addition, the Craycoat was operated for 6 months to evaluate the alignment of the line belt. In the case of the comparative example, a partial distortion of the line belt occurred. appeared not to be possible. On the other hand, in the case of the example, the line belt was found to be shifted up to 3 mm from the original position, and it was confirmed that the stability of the surface layer structure was improved when applied to the clay coat. It is understood that this is because structural stability is further improved by applying a line belt suitable for the components constituting the surface layer structure or the layer thickness and the surface layer structure in the present invention.

The embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and examples.
