Description

[0001] The artificial turf drainage blocks [0002]

The present invention relates to a drain block for artificial turf, and more particularly to a drain block for artificial turf, which can exhibit increased collection performance per unit area of artificial turf mat, while ensuring durability to withstand a sufficient load like a conventional drain block, It is possible to assemble irrelevantly. In addition, when the drainage blocks are contracted or relaxed in response to external temperature changes, the binding sites can be controlled correspondingly, and the antimicrobial performance and the adhesion of organic substances contained in water can be prevented to form harmful scale layers such as mosses and fungi The present invention relates to a water drainage block for artificial turf.

It is desirable to plant natural turf in the outdoor baseball field and soccer field. However, since the turf is often damaged due to intense exercise, natural turf has considerable manpower and cost in maintenance and management.

In order to solve this problem, artificial turf made of artificial turf has been used for a long time since it was first produced in the United States. It has been used mainly for sports stadiums and has been used in indoor gardens where grass growth is not possible, It is widely used in places such as the outdoors facing north.

In addition, artificial turf is always kept green and is not restricted by environmental conditions, so it is easy to manage after construction. It has a higher initial construction cost than natural turf, but it can be used semi-permanently, The preference is high because of this.

Such artificial turf has a plurality of piles having a length of about 20 to 70 mm fixed on the nonwoven fabric and a drain block for artificial turf is laid between the nonwoven fabric and the ground to prevent breakage of the nonwoven fabric and improve drainage.

Particularly, the drain block for artificial turf is made of a square plate, and a plurality of drainage protrusions are provided on the upper surface to give elasticity. In the space between the drainage protrusions, have.

However, in the conventional drainage block, when the joint portion is broken, the gap between the drainage blocks is widened or the height of the upper and lower portions is changed, and a large amount of water seeps through the damaged portion to the ground.

Accordingly, the drainage block is designed so that the drainage block can be shrunk and expanded according to the external temperature change while the artificial turf construction does not easily separate the joint portion while enduring sufficient impact load in order to minimize the above- Or international standards are standardized and thoroughly managed.

Korean Unexamined Patent Publication No. 10-1098896 entitled "Artificial lawn athletic drain block, drainage system and method of construction ", which is a first prior art related to such a conventional drainage block, has been disclosed.

Japanese Unexamined Patent Publication No. 10-1363159 entitled "Drain block" discloses a second prior art in which the shape of the drain protrusion is a quadrilateral.

As a third prior art, there is disclosed Korean Patent No. 10-1444728 entitled "Artificial Turf Drainage Block ", in which the shape of the drainage protrusion is triangular. In the fourth prior art, Japanese Patent No. 10-1363159 discloses a "drainage block ".

The drainage protrusions of the drainage block according to the first to fourth prior arts described above have a simple shape such as a circular shape, a square shape, a triangle shape, and a diamond shape.

The horizontal and vertical dimensions of artificial turf drainage block are 300 × 300 and allow up to 330 × 330 considering the overlapping overlapping area size. With this KS standard, the spacing of drainage projections is maintained at 10 mm And the outer diameter, height and spacing of the drainage projections are limited within the overall permissible impact load.

Accordingly, since the water collecting area between the drainage protrusions of the conventional drainage block is very limited, the space for receiving the water permeated to the lower part of the artificial grass at the time of raining is also limited.

Therefore, when the amount of precipitation is small, the drainage performance is good. However, when the amount of precipitation is large, the drainage performance per unit area of artificial turf is drastically decreased because the drainage area of one drainage block is exceeded. And the use of artificial turf was limited in the case of heavy rainfall.

In addition, since the drainage protrusion of the conventional drainage block has a flat upper surface to support artificial turf and has to maintain a thickness of at least 1 mm to a maximum of 3 mm in order to withstand an impact load, the upper surface of the drainage protrusion The center is depressed.

therefore. As a result, a large amount of water is stored between the synthetic grass and the upper surface of the drainage pavement, and water is accumulated on the upper surface of a large number of drainage pavements.

In the second prior art, a cross-shaped drainage groove is formed to solve this problem. However, since the drainage groove bottom of the conventional art has a simple plane, when the center of the drainage groove is contracted by injection molding, The problem that the drainage is not performed well as described above can not be solved yet.

In addition, since the upper surface of the drainage protrusion of the conventional drainage block has a smooth low-friction surface, artificial turf can be easily pushed when the artificial turf is raised on the artificial turf after the construction, so that the artificial turf is pushed, There was a problem.

In this case, the conventional drainage blocks have a problem that the drainage blocks are separated from each other as the drainage block is moved or lifted due to the interference tolerance between the fastening protrusions and the fastening holes of the fastening holes.

In addition, when the external temperature suddenly becomes high or low in the summer or winter season, the drainage block expands or shrinks due to the nature of the material, and the drainage block is lifted so that artificial turf is also lifted. So that the original state can not be restored.

Since the conventional drainage block is mainly buried in the ground, it is defined as a drainage block for recycled plastic landscaping according to the KS standard.

Therefore, most of the drainage projections of the related art are not provided with any reinforcing structure for maintaining sufficient strength on the outer side, and are easily damaged by fatigue load for a long period of use. Therefore, There was a troublesome problem of replacing a part of the block or replacing the entire drainage block of a certain area, and there was a problem that the maintenance cost was increased.

Further, since the conventional drainage blocks are installed under the artificial turf and are not exposed when viewed from the outside, the entire surface can not be injection-molded smoothly, and the surface of the reclaimed resin itself is only roughly formed by injection molding at a high temperature .

As a result, the organic matter contained in the water discharged from the rains can be easily adhered to the rough surface of the drainage block, and the water that does not sufficiently drain can propagate the moss or the mold, and the scale layer caused by the organic matter causes the odor Such as the occurrence of a serious problem was unhygienic.

The artificial turf drainage block according to the present invention aims to solve the following problems.

First, it provides a reinforced structure that can withstand a sufficient load such as a conventional drainage block, and at the same time, it provides an increased collecting area per unit area of artificial turf matte so that an artificial turf drainage block capable of exhibiting excellent draining ability even in a rainy season .

Second, it is intended to provide a drain block for artificial turf which can maximize the drainage performance by preventing a small amount of water from remaining between drainage projections and artificial turf.

Third, by increasing the friction force between the drainage projections and artificial turf, even if artificial turf is pushed by the intense movement, the drainage protrusion can securely hold the drainage block according to the soil condition of the ground, And to provide a water drain block for artificial turf that can minimize the jarring phenomenon.

Fourth, even if the gap between the drain blocks is contracted or relaxed corresponding to the external temperature change regardless of the arrangement direction of the drain blocks, the drainage blocks can be contracted or relaxed together so that the drainage block can be easily lifted, So as to prevent damage to the artificial turf.

Fifth, it is possible to prevent adsorption of organic substances contained in water drained on the entire surface of a drain block, to continuously release far-infrared rays, anion and antimicrobial components, thereby suppressing the propagation of harmful bacteria, Drainage < / RTI >

That is, the existing drainage projections 20 should be limited to 20 mm to 25 mm in maximum height including the thickness of the base plate 10 according to the KS standard, and the spacing of the drainage projections 20 should be maintained at 10 mm .

Therefore, in order to increase the impact load of the drainage protrusion 20 or to increase the drainage capacity, it is very difficult to change the size or the interval of the drainage protrusion 20 because it is restricted by the KS standard .

Accordingly, the conventional drainage block 100 must have a limited collection capability per unit area of artificial turf and must maintain durability to withstand a sufficient impact load. Therefore, the shape and thickness arrangement interval of the drainage protrusions 20 I could not easily change it.

The present invention can be configured as a new constitution of the drainage block having drainage protrusions to which the catchment reinforcement grooves 30 are applied, which can increase the catchment area while maintaining sufficient strength even under such restrictive conditions.

According to another embodiment of the present invention, the water collecting reinforcement groove 30 in the water drainage protrusion 20 may be formed in a shape of a triangle drainage protrusion (as viewed in a plan view of the water drainage protrusion 20) And the water collecting reinforcement groove 30 may be formed in a polygonal shape such as a rectangular drainage projection 23, a pentagonal drainage projection 24, a hexagonal drainage projection 25, and a rhombic (or parallelogram) drainage projection 28, May be respectively formed at the corners of the polygon.

According to another embodiment of the present invention, the drainage protrusion 20 is formed of a circular drainage protrusion 26 as viewed in plan view, and the water collection reinforcement groove 30 is formed as shown in the left side of FIG. 1F Can be configured.

When the number of the water collecting reinforcement grooves 30 is four, the water collecting grooves 30 may be radially arranged at an angle of 90 degrees with respect to the center of the circle. When a plurality of water collecting reinforcement grooves 30 are provided as shown in FIG. Lt; / RTI >

According to another embodiment of the present invention, the drainage protrusion 20 is formed of an elliptical drainage protrusion 27 as viewed in a plan view, and a plurality of the water collection reinforcement grooves 30 are formed as shown in the left side of FIG. Can be configured.

When the number of the water collecting reinforcement grooves 30 is four, the water collecting reinforcement grooves 30 may be formed at positions facing each other on the short axis and the long axis of the ellipse, and may be formed diagonally as shown on the right side of FIG.

According to the structure of the water collecting reinforcement groove 30, a space for accommodating more water can be secured in the space of the water collecting reinforcement groove 30 than the water collecting area formed by the existing drainage projections 20.

The water collecting reinforcement grooves 30 are formed in the center of the water discharging protrusions 20 and are integrally formed by the injection molds. Therefore, the water collecting reinforcing grooves 30 can be formed of a simple polygon having no groove on the outer surface, The drainage protrusion 20 of the present invention having the water collecting reinforcement groove 30 can be easily broken even if a severe impact is applied on the artificial turf mat 300 because the durability against the impact load is greatly improved as compared with the drainage protrusion 20 The effect will go out.

According to the present invention, although not specifically shown in the drawings, the upper surface of the drain protrusion 20 may further include fine protrusions for preventing slippage with the bottom surface of the artificial turf mat 300.

According to the present invention, the fine protrusions are formed on the surface of a female mold (not shown) for molding the drain protrusion 20 by micro-projection forming grooves (not shown) formed by machining that is selected during corrosion processing, sanding processing, And may be integrally formed with the drainage protrusion 20.

Accordingly, the fine protrusions can be formed in various pattern patterns that can be formed in a mold such as a dot shape, a stripe shape, or the like on the upper surface corresponding to various shapes of the drain protrusions 20. In addition, , And a square pyramidal shape so as to increase frictional force with the artificial turf mat (300).

As described above, the drain block 100 according to the present invention provides a micro protrusion capable of increasing frictional force with the bottom surface of the artificial turf mat 300 on the upper surface of the drain protrusion 20, thereby minimizing the shrinking action during injection molding The artificial turf mat 300 is stably fixed so that artificial turf is not pushed at all even when the artificial turf is exercised violently.

In the meantime, according to the present invention, when the drain block 100 is easily coupled and the connection structure expands or contracts due to the temperature of the drain block 100 made of a resin system in response to a change in the external temperature, So that the drain block 100 is not lifted or deformed.

As shown in FIGS. 5, 7 and 8, first and second connection portions 11 and 12 extend in the same line on the edge of the base plate 10, for example.

A third connecting portion 13 extending on the bottom surface of the base plate 10 so as to overlap with the first connecting portion 11 and the second connecting portion 12 of the other drain block 100 is formed at the opposite edge of the first connecting portion 11 and the second connecting portion 12, And a fourth connecting portion 14 are provided.

The first connecting portion 11 and the second connecting portion 12 are provided with a pair of locking projections 42 having a size enlarged to an outer diameter larger than the outer diameter of the fitting pin 41 projecting downward from the bottom surface The projections 40 are protruded.

In the third connection part 13 and the fourth connection part 14 are formed a fastening hole 50 having two pairs of engagement protrusions 51 formed to face each other in the transverse direction or the longitudinal direction in which the base plate 10 is arranged, .

The outer diameter of the fitting pin 41 and the inner end of the engaging protrusion 42 and the clearance difference between the engaging protrusion 42 and the engaging protrusion 42 are larger than the outer diameter of the fitting pin 41, It is desirable to maintain a tolerance that is proportional to the coefficient of thermal deformation corresponding to the material of the base plate 10.

According to this construction, when the temperature of the drain block 100 itself expands due to geothermal heat or solar heat when the temperature rises as in the summer, each of the fitting pins 41 is placed in the drain block 100 It is possible to minimize the deformation of the base plate 10 of the drain block 100 due to the convex deformation of the drain block 100 due to the minute lengths of the insertion pins 41 moving outwardly between the latching protrusions 51.

On the other hand, when the air temperature drops to minus zero as in the winter, when the base plate 10 of the drain block 100 is contracted, the fitting pin 41 is contracted in the tolerance with the engaging step 51, The pin 41 is pulled between the engaging shoulders 51 and moved finely so that the base plate 10 of the drain block 100 is not buried and the fitting pin 41 is prevented from coming into contact with the engaging shoulder 51 So as to maintain the coupled state.

The upper surface of the engaging jaw 51 and the lower surface of the engaging projection 42 are formed with inclined surfaces 43 and 52 so that when the jaw protrusion is fitted into the engaging hole 50, The inclined surface 43 is guided by the inclined surface 53 of the engaging jaw 51 so that the engaging jaw 51 is slightly pushed outward and then the engaging protrusion 42 is retracted and then retracted to facilitate fitting operation, On the contrary, can not be easily separated.

The engaging protrusions 42 and the engaging shoulders 51 are engaged with each other in a region larger than the tolerance d as described above so that the fitting pin 41 is caught between the engaging shoulders 51 It is preferable that the latching state is maintained even if it is moved.

According to another embodiment of the present invention, a protective layer 60 in the form of a liquid or film is disposed on the entire outer surface of the base plate 10 and the drainage protrusion 20 so as to emit far-infrared rays and negative ions to prevent antibacterial and organic matter adsorption. .

Examples of the components contained in the protective layer 60 include tourmaline, guillotine, hegery, ocher, pine gin, sericite, elvan, cryptomeric, germanium, charcoal, pine bark, and lacquer produced in powder or liquid form to emit anion itself , And zeolite.

According to another embodiment of the present invention, the drainage block 100 is formed by injection molding with a synthetic resin, such as tourmaline, Guiyang stone, Hegelion, loess, pine crust, sericite, elvan, cryptite, germanium, Any one component selected from the shell, lacquer, and zeolite may be mixed by injection molding at a ratio of 5% or less based on 100% by weight of the injection resin material for injecting the drainage block 100.

It is preferable that the functional components added to the drain block 20 are mixed with the injection resin material for injection molding at a ratio of 5% or less and mixed within a limit not to interfere with the injection flow .

In particular, tourmaline is a tourmaline stone that generates the most electrons in the natural stone.

The negative (-) electrons are generally excellent for interfering with the binding of the (+) anion and (-) anions in the water, or for interrupting the molecular bond, ie, hydroxyl or interfacial action.

For example, the use of soap in the hands of the hand oil in the grease is the principle of the-electron activity, that is, hydroxyl function or surfactant.

If the (-) electrons act on the water passing through the artificial turf, it is possible to prevent the formation of scale layers by preventing various organic components contained in water from adhering to the surface of the drain block 100, And is very effective in disassembling and removing the scale layer already adhered to the surface of the drain block 100.

As described above, in the present invention, a material such as tourmaline for inhibiting adhesion of organic substances is processed into a powder or a liquid and then mixed with a material for forming the drain block 100 or the protective layer 60 at an appropriate ratio, It is effective to prevent adsorption of organic matter.

Therefore, it is possible to prevent the formation of moss and fungi by the organic matter in the water drained through the artificial turf mat 300, and to prevent malodorous or harmful gas from being generated.

The protective layer 60 may be formed by a chromium plating process or a spraying process depending on the synthetic resin material of the drain block 100 so that the surface roughness of the base plate 10 and the drain protrusion 20 So as to prevent adsorption of organic substances.

In addition, the protective layer 60 may be formed of various functional films having good surface roughness in order to prevent adsorption of an antibacterial component, far infrared rays, anion emission component, and organic substances, which suppress the bacterial growth, It can be formed in a form of attaching to the entire surface.

For example, the functional film is injection-molded into the inner side of the film while the mold is closed while passing through the lower mold and the upper mold of the mold during injection molding of the drain block 100, The protective layer 60 can be formed by insert-molding uniformly over the entire surface of the protective layer 20.

According to another embodiment of the present invention, the fixing device may further include a fixing hole 70 vertically penetrating the base plate 10 through the drainage protrusions 20 or between the drainage protrusions 20 .

The fixing hole 70 may be formed at least in the middle and at the four corners of the drain block 100. The fixing hole 70 may be formed in the finishing hole 70 ). ≪ / RTI >

A packing 75 made of a rubber or silicone material is interposed between the finishing cap 71 and the fixing hole 70. The fixing hole 70 and the finishing cap 71 can be assembled with a tight fitting tolerance through the gap between the fixing hole 70 and the finishing cap 71 It is preferable to prevent the water from being drained to the ground.

When the fixing hole 70 is formed at the position of the drain protrusion 20, the shape of the finishing cap 71 is the same as the shape of the drain protrusion 20, and a plurality of assembly protrusions 76, It is preferable to support the artificial turf mat 300 together with the other drainage protrusions 20 by fixing the artificial turf mat 300 after being fitted to the fixing hole 70 by means of the other drainage projections 20.

The fixing hole 70 is for fitting the fixing member 72 for firmly fixing the drain block 100 to the ground 200 before the artificial turf mat 300 is installed.

For example, the fixing member 72 includes a head cap 73 having the same shape as the drain protrusion 20 and a mounting portion 74 for mounting the finishing cap 71 in the ground.

The drainage block 100 has a diameter and a length that are the same as or slightly smaller than the inner diameter of the fixing hole 70 that can be embedded in the ground so as to be fixed to the ground surface 200 and have a pointed end.

According to the fixing member 72, the drainage block 100 may be installed or the drainage block 100 may be unstable or flowable immediately before the artificial turf mat 300 is installed, It is possible to remove the finishing cap 71 and securely fasten the fixing member 72 to the ground surface 200 with respect to the ground surface 100 of the drainage block 100.

At this time, since the head portion 73 of the fixing member 72 has the same shape as that of the drain protrusion 20, it is needless to say that the artificial turf mat 300 can be stably supported.

In the meantime, according to the present invention, a drain slant groove 21 may be formed on the upper surface of the drain protrusion 20.

The drain slant grooves 21 are formed in the drain slant grooves 21 on the basis of the center point of the drain slant 20 when viewed in plan from the drain slant 20 as shown in Figs. The angle may be configured to maintain 90 degrees, and may be variously formed in the horizontal and vertical directions or the diagonal direction with respect to the direction in which the base plates 10 are arranged.

The bottom surface of the drain slope groove 21 may be inclined downward from the center of the drainage protrusion 20 toward the drainage passage 15 between the drainage protrusions 20.

The inclination angle of the drain slope groove 21 may be changed by changing the inclination angle in consideration of the shape and drainage speed of the drainage protrusion 20, but it is preferable to maintain an inclination angle within 45 degrees.

In addition, chamfered portions or rounded portions of at least 1 mm or more may be formed on the corner portion where the upper surface and the outer surface of the drainage protrusion 20 meet and the outlet side edge portion of the drainage slanting groove 21.

The upper edge of the drainage protrusion 20 secures a clearance between the bottoms of the artificial turf mat 100 when the corners and the round part are in contact with the bottom of the artificial turf so as to be sandwiched between the artificial turf mat 100 and the upper surface of the drainage protrusion 20 Thereby allowing the water to be discharged smoothly to the outside and allowing the water to be completely discharged through the drain slant grooves 21 to the drain passage 15.

The chamfered portion or the rounded portion also serves to prevent the artificial turf mat bottom from being torn and torn by the sharp edges.

The present invention is not limited to the above-described embodiments, but may be modified in various ways within the spirit and scope of the present invention as set forth in the claims below. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
