Description

Road sheet {Road sheet}

The present invention relates to a road sheet.

In general, on the surface of concrete and asphalt pavement materials applied to sidewalks or roads, road information necessary for driving, including direction signs and speed limit signs, and road situation information such as crosswalks, school signs, and bus-only lane signs, and physical education And bicycle road markings are displayed on the surfaces of elastic paving materials applied to play facilities or walking paths, and waterproof paving materials applied as internal flooring materials of buildings, etc., or waterproof flooring materials for rooftops.

These road signs are in front of schools according to Article 4 of the Road Traffic Act, Article 3, Paragraph 2 of the Enforcement Rule of the same Act, and various road signs prescribed in the Police Agency Traffic Road Sign Installation and Management Manual and Article 11, Paragraph 2 of the Road Traffic Act. Or road signs such as in front of a kindergarten (School-Zone), an elderly protection area (Silver-Zone), and a youth curfew zone (Red-Zone) under the Youth Protection Act.

Road surface signs such as road surface signs, letters, numbers, and various designs provide information for safe driving or walking to vehicles, bicycles, and pedestrians using the road, and function to maintain driving order.

In particular, these road markings enable the driver to easily identify lanes on the paved road by reflecting light generated from the headlights of the vehicle when driving the vehicle at night when the road surface is wet due to snow or rain, as well as the risk of traffic accidents. They should be marked on the surface of the road surface to minimize disruption to the traffic flow.

In addition, road signs constructed on school roads are required to have anti-skid effects to prevent accidents caused by slipping of vehicles in rainy weather.

As a conventional method for installing such road signs, a method of displaying by operating a construction machine in the field using normal temperature paint or fusion-type road sign paint using general paint, or installing using an adhesive sheet is mainly used. .

However, in the case of normal temperature type paint among the above conventional methods, the coating film is thin and the durability is poor, and it requires a drying time of 30 to 50 minutes, which hinders traffic flow, and the temperature during operation is room temperature 5 There is a defect that it is difficult to work in winter because it is impossible to work below ℃.

On the other hand, in the case of fusion-type paint, since it is worked using fusion-dissolution equipment at the site, it causes traffic congestion due to complicated equipment such as vehicles for this, and it is impossible to apply a certain thickness by directly painting the road during construction, There are problems in that retroreflection falls at night due to non-uniform settling of reflectors due to artificial spraying of reflectors through manual machines in the field, and glass beads applied unevenly on the surface are easily separated.

In order to solve these problems, heat-melting paints in which thermoplastic resins and pigments are mixed are used in terms of quick-drying and durability, but the trouble of construction and long-term road occupancy still remain, and visibility at night in rainy weather is still It's not something you can be satisfied with.

In addition, in the case of such room temperature paint and fusion type paint, it is difficult to express complicated patterns and colors, and there is an inconvenience in not satisfying the changing relationship regulations.

That is, Korean Patent Registration No. 690277 suggests a paint for road marking, but it mainly improves the function as an anti-settling function, and the function as preventing cracks and slipping after painting includes large-diameter glass beads and hard aggregate. As a result, these grains were separated and separated in a short period of time due to the impact of the wheel of the vehicle, resulting in a decrease in durability, resulting in cracks, and a problem in that the anti-skid function quickly deteriorated.

On the other hand, compared to on-site painting with paint, the construction time is shorter and the expression of various shapes and colors is relatively free in the case of the adhesive sheet, which overcomes the peeling phenomenon caused by moisture penetration, dust, moisture, etc. due to the inability to treat the gaps on the road surface It is difficult to cut, and has various defects such as material loss after cutting.

In addition, the conventional construction methods described above have a problem in that the cycle of discoloration and wear is short, resulting in ever-increasing traffic congestion due to repeated construction work while controlling the road frequently.

In addition, since most of the paints used for lane work on roads are volatile oil paints, the problem of environmental pollution caused by volatile substances during construction and substances abraded by vehicles after construction is emerging as a new problem. It is becoming.

In order to solve these problems, Korea Patent Registration No. 740296 proposes a thermoplastic hot melt tape for road marking and a construction method using the same.

According to the registered patent, a driving driver can easily identify the alignment of the road even at night or in rainy weather, can complete construction and repair work within a short time, and the glass bead reflector applied on the surface of the hot melt tape does not easily break away A hot melt tape for road marking that can be used simultaneously for lane and anti-slip is provided.

However, in the case of the registered patent, the glass beads are equally distributed throughout the hot melt, so when the light of the headlight shines on it, both the part displaying road information and the part that does not, are reflected, so the driver's ability to distinguish road information is quite weak. There is a fundamental problem that makes it impossible to clearly recognize and a defect that is more difficult to identify, especially at night and in rainy weather. In this case, there is a problem that the state of the road surface is expressed as it is, and the splendor of the exterior is lost.

In addition, when the registered patent is installed on a permeable road surface, the corresponding part is easily inflated due to substances such as water vapor discharged from the road surface in summer, and in particular, if the inflated part is left unattended continuously, the corresponding part may be damaged by passing vehicles or pedestrians. There is a problem that it is quickly worn or damaged and needs to be rebuilt.

The present invention can increase surface friction by additionally sprayed sand, so that even if the surface is wet, the risk of safety accidents such as a pedestrian or vehicle slipping and falling or an increase in braking distance can be significantly reduced.

In addition, it is possible to firmly fix the sheet to the road surface through a fixing mechanism that penetrates the seat and is embedded in the road surface, and is particularly useful as vaporized substances can be discharged through the passage of the fixing mechanism, forming a barrier in the passage As a result, there is an advantage in fundamentally solving the problem that foreign substances from the outside flow into the flow path and block the flow path.

Hereinafter, it will be described in detail based on the accompanying drawings.

1 to 3 are combined perspective views, exploded perspective views, and main cross-sectional views of a road sheet according to the present invention.

1 to 3, the road sheet 1 of the present invention according to an embodiment includes a background part 11 having different colors, a display part 12, glass beads 13, and sand 14 and a fixing mechanism 20.

The display part 12 is a letter, a symbol, or a number, and the background part 11 and the display part 12 are coupled to each other like a puzzle.

In addition, the glass bead 13 applied a luminous reflectance of 85.3%, and the measurement method followed the standard of JIS K 5665.

For reference, the luminous reflectance refers to the ratio between the light flux reflected from the object surface and the light flux incident on the object surface.

In addition, the display portion 12 includes glass beads 13 relatively more than the background portion 11 .

In this way, if more glass beads 13 are included in the display portion 12 than in the background portion 11, the glass beads 13 exposed to the outside are also relatively more, so that the headlights of the vehicle light up the background portion ( 11) and the display unit 12, the display unit 12 reflects relatively more light than the background unit 11, thereby making the distinction between the background unit 11 and the display unit 12 clear. Accordingly, the display unit 12 is relatively more prominent than the background unit 11 to improve discrimination, so the vehicle driver can quickly recognize the information displayed on the road through the raised display unit 12, especially at night or in rainy weather. Information transmission can be improved through discernment.

In addition, in the background part 11 and the display part 12, fine holes 11a and 12a communicated from the surface of the background part 11 and the display part 12 to the road surface so that the vaporized material discharged from the road surface can be discharged to the outside. ) is integrally formed.

Meanwhile, irregular sand 14 is further included in the background part 11 and the display part 12 .

Here, the sand 14 is a grain of sand having a size similar to that of the glass beads 13, and is formed on the background part 11 and the display part 12 to increase surface friction. Accordingly, even if the surface is wet, pedestrians or vehicles It can significantly reduce the risk of safety accidents such as slipping and falling or increasing the braking distance.

In addition, the background part 11 and the display part 12 are firmly fixed to the road surface via the fixing mechanism 20.

4 is a perspective view and a cross-sectional view of a fixing mechanism separately extracted from a road sheet according to the present invention, which will be described with reference to this.

The fixing mechanism 20 is composed of a pile part 21, a plunge part 22, and a concave-convex part 23 and is integrally manufactured.

The pile part 21 is a member whose lower end is closed and the upper end is open, and a flow path 21a is formed on the inside and an inlet hole 21b communicating with the flow path 21a is integrally formed on the outer surface to discharge from the road surface. The vaporized material may be discharged to the outside through the inlet hole 21b and the flow path 21a.

The lower end of the pile part 21 is preferably formed in a conical shape with a sharp tip so that it can easily dig into the road surface when hitting with a hammer.

The plunge portion 22 extends horizontally from the outer circumferential surface of the pile portion 21, and serves to press the background portion 11 and the display portion 12 so that they adhere to the road surface.

The concave-convex portion 23 is formed by knurling the upper surface of the plunge portion 22, and serves to prevent slipping of vehicles or pedestrians.

On the other hand, the fixing mechanism 20 is likely to block the inlet hole 21b or allow foreign matter to enter the passage 21a through the inlet hole 21b during the process of being embedded in the road surface, thereby removing vaporized substances. There may be difficulty in discharging.

4 is another modified example of a fixing mechanism devised to solve the above problems, and will be described with reference to FIG. 4 as follows.

The fixing mechanism 20' is composed of a pile part 21', a plunge part 22', a concave-convex part 23, and a drilling nail 24.

The pile part 21' is a pipe through which the inside is vertically penetrated, and a flow path 21a is formed therein, and the pointed part of the lower end is truncated.

The plunge portion 22' extends horizontally from the outer circumferential surface of the upper end of the pile portion 21'.

A seating groove 22a is recessed at the center of the plunge portion 22', and the seating groove 22a communicates with the passage 21a.

In addition, a screw tap is formed on the inner circumferential surface where the seating groove 22a is formed, so that it is screwed with the head 24b of the drilling nail 24 to be described later.

A concave-convex portion 23 is integrally formed on the upper surface of the plunge portion 22', and the concave-convex portion 23 is formed by knurling the upper surface of the plunge portion 22. It serves to prevent pedestrians from slipping.

The drilling nail 24 is inserted through the pile part 21' and detachably screwed to the plunge part 22', and then, when the pile part 21' is driven into the road surface, the pile part 21' and It is removed by separating it from the plunge part 22'.

The drilling nail 24 is formed integrally with the nail body 24a protruding from the lower end of the pile part 21' and the upper surface of the nail body 24a, and is inserted into the seating groove 22a to form a plunge portion. (22') and a detachably screwed head (24b).

In addition, a driver groove is integrally formed on the upper surface of the head 24b so that a worker can release the head 24b screwed to the plunge portion 22' using a screwdriver or the like.

According to this embodiment, since the inlet hole 21b is not formed on the outer circumferential surface of the pile part 21', it is possible to fundamentally solve the problem of inflow of foreign substances while the pile part 21' is embedded in the road surface. In addition, when the drilling nail 24 is removed, there is an advantage in that the discharge of the vaporized material can be more smoothly as the flow path 21a is formed in a straight line.

On the other hand, in the case of the previous embodiment (see FIGS. 4 and 5), as the passage 21a is exposed to the upper end of the pile parts 21 and 21', foreign substances easily flow in from the outside when vehicles or pedestrians repeatedly pass by. There is a serious problem that the passage 21a is closed, and furthermore, the function is lost in that foreign substances in the passage 21a cannot be removed without the pile parts 21 and 21' being pulled out from the road surface. there is

Therefore, in this embodiment, in order to solve the above problem, a cover 25 and a blocking film 26 are formed in the seating groove 22a from which the drilling nail 24 is removed, as shown in FIG. 6 .

In addition, the plunge portion 22 of the fixing mechanism 20 shown in FIG. 4 was also formed with a screw tap on the seating groove 22a and the inner circumferential surface of the seating groove 22a.

6 is an exploded perspective view showing that a cover and a shielding film are applied to different fixing mechanisms in a road sheet according to the present invention. , and (b) is a view in which the cover 25 and the blocking film 26 are applied to the fixing mechanism 20' of the second embodiment.

Referring to (a) and (b) of FIG. 6 , the cover 25 is inserted into the seating groove 22a and is detachably combined with the plunge portion 22'.

In addition, on the upper surface of the cover 25, a driver inserts the cover 25 into the seating groove 22a using a screwdriver or the like to screw it together or to separate the screwed cover 25 from the seating groove 22a. It is formed as a whole.

In addition, a discharge hole 25a communicating with the passage 21a is integrally formed at the center of the cover 25, and may be modified according to the size and arrangement of the discharge hole 25a.

The blocking film 26 is accommodated in the seating groove 22a and fixed by the cover 25 .

The blocking film 26 fixed in this way blocks foreign substances (water, dust, stones, etc.) from the outside, and vaporized substances moved through the passage 21a are discharged.

To this end, the blocking film 26 is a known Gore-Tex in which countless fine holes are formed by stretching and heating a Teflon-based resin that is resistant to heat or chemicals.

According to the present embodiment, as the blocking film 26 blocks the exposed flow path 21a, it is possible to prevent foreign substances from entering the flow path 21a from the outside, thereby solving the problem of loss of the original function of the flow path 21a. can be fundamentally eliminated.

In addition, convenience in use can be maximized in that the blocking film 26 can be easily replaced and removed even if the blocking film 26 is damaged or foreign substances are accumulated on the blocking film 26 .

Next, the road sheet construction method according to the present invention will be described.

4(a) to 4(h) are flow charts showing the construction process of the road sheet according to the present invention, where FIG. 4(a) is a view showing an adhesive applied to the road surface, and FIG. 4(b) shows adhesion 4(c) is a drawing in which the liquid sealant is sprayed with reinforcing wire, FIG. 4(d) is a drawing in which a reinforcing material is installed on the reinforcing wire, and FIG. 4(e) is a drawing in which an adhesive and 4(f) is a drawing in which the liquid sealant, reinforcing wire, and reinforcing material are integrally combined, FIG. 4(f) is a drawing in which a primer is applied to the reinforcing material, and FIG. It is a drawing showing the state.

The construction process of the road sheet 1 according to the present invention will be sequentially described with reference to FIGS. 4(a) to 4(g).

(1) First step

Referring to FIG. 4(a), after determining the location to be installed, the road surface 100 to which the road sheet 1 is to be attached is cleaned and dust is removed using a cleaning tool (eg, broom, vacuum cleaner, etc.).

Then, the adhesive 200 is evenly applied to the road surface 100 in a predetermined amount (for example, 0.4 ℓ to 0.6 ℓ/m 2 ).

Here, the adhesive 200 means a conventional asphalt adhesive used in asphalt pavement.

(2) The second stage

Referring to FIG. 4(b) , when the adhesive 200 is evenly applied to the road surface, a liquid sealant 300 is applied to the adhesive 200 at a predetermined thickness (for example, 2 mm to 2.5 mm).

Here, when the thickness of the sealant 300 is less than 2 mm, the sealant 300 cannot be introduced to the reinforcing material 500, resulting in a problem of weakening the buffering function, elasticity, and binding force, and the thickness of the sealant 300 If it exceeds 2.5 mm, there is a problem that the stretching force is too strong and can be torn by the reinforcing wire 400 during stretching deformation.

For reference, the sealant (sealant) 300 is a rubber-like material or a soft or high-viscosity liquid rubber composition for absorbing and alleviating expansion, vibration, and deformation between members.

(3) The third stage

Referring to FIG. 4(c), before the sealant 300 hardens, the reinforcing wire 300 is irregularly (without directionality) scattered on the sealant 300.

Here, the reinforcing wire 300 is a member having a diameter of 100 μm to 200 μm and a length of 5 mm to 10 mm, and in the case of the present embodiment, it is fixed by the sealant 300 to prevent excessive It functions as a medium that prevents stretch deformation and cracks, and improves the binding force between the reinforcing material 500 and the sealant 300 so that both members are securely fixed.

And after spraying the reinforcing wire 300, as shown in FIGS. 4(d) and 4(e), the reinforcing wire 400 is covered with the reinforcing material 500, and at this time, the sealant 300 is cured. It is preferable to install before

The reinforcing material 500 is made of a non-woven fabric having a thickness of 1.5 mm to 2 mm in which glass fibers, polypropylene fibers, and arabic fibers are irregularly arranged without directionality.

In particular, in the case of the reinforcing material 500, since glass fiber, polypropylene fiber, and arabic fiber are entangled with each other, there are abundant air gaps, and the sealant 300 flows into the air gap, and at the same time, a part of the reinforcing wire 400 can be inserted together.

For reference, briefly describing the manufacturing of the reinforcing material 500, glass fibers, polypropylene fibers, and arabic fibers having a fine diameter are put together in one barrel, pressurized with a press to make a nonwoven fabric, and then radially It is fixed so that it does not come loose by stitching or using an adhesive.

Here, the glass fiber has high strength characteristics with no tearing and less breakage due to knitting, etc., the polypropylene fiber is not only stable compared to other fibers, but also has excellent water and corrosion resistance properties, and the aramid fiber is a fiber by temperature There is no displacement in the longitudinal direction, and the tensile strength is excellent enough to lift a large object, and it does not burn even at a high temperature of 500 ° C.

That is, the reinforcing material 500 is fundamentally very easy to manufacture while having considerably excellent toughness, heat resistance, and tensile strength.

On the other hand, when the reinforcing material 500 is pushed with a roller in a state where the reinforcing wire 400 is covered with the reinforcing wire 500 as described above, the sealant 300, the reinforcing wire 400, and the reinforcing material 500 is compressed, and the reinforcing wire 400 is wrapped by the sealant 300 and the sealant 300 flows into the reinforcing material 500 at the same time.

After sufficiently pressing with a roller, the sealant 300 is cured and sufficiently naturally dried so that the adhesive 200, the reinforcing wire 400, and the reinforcing material 500 can form an integral structure with each other through this medium. In midsummer when the temperature is high, cooling by spraying water can be one way.

According to the present embodiment, as described above, the adhesive 200, the reinforcing wire 400, and the reinforcing material 500 form an integral structure with the sealant 300 as a medium, so that the displacement for thermal contraction/expansion can be sufficiently endured, In particular, when the road sheet 1 is constructed, even if the vehicle load acts on the road sheet 1, the resistance to absorption and relaxation of expansion, vibration, and deformation of the load displacement can be increased, which can greatly reduce the risk of damage There is an advantage.

(4) The 4th stage

Referring to FIG. 4(f), the primer 600 is sufficiently applied to the surface of the reinforcing material 500 using a brush.

In particular, when applying the primer 600 to the reinforcing material 500, it is preferable to apply the primer 600 so that the recessed part can be sufficiently filled by the primer 600, because the primer 600 is applied to the recessed part. If this is not done, foreign substances, etc. flow into this gap and weaken the binding force between the reinforcing material 500 and the primer 600, and this causes a problem in that the road sheet 1 installed on the primer 600 is peeled off and needs to be re-installed.

After applying the primer 600, the primer 600 is dried. In particular, it is preferable to dry the primer 600 for a sufficient time until the primer 600 does not come off even when touched with a finger. As long as the primer 600 is widely known in the field of road sheet construction, it can be used without particular limitation.

(5) The 5th step

Referring to FIG. 4(g), when the primer 600 is sufficiently dried, the background part 11 and the display part 12 having glass beads 13 exposed to the outside of the primer 600 and having different colors are formed. ) The road sheet 1 composed of is mounted.

At this time, the road sheet 1 includes glass beads 13, and in a road sheet composed of a background portion 11 and a display portion 12 having different colors, the display portion contains more glass beads 13 than the background portion. that has been included

(6) The 6th step

Referring to FIG. 4(g), the road sheet 1 may be heated using a torch 700 while the road sheet 1 is placed on the primer 600. ) is applied as a whole to check whether the road sheet 1 fits well into the reinforcing member 500 constituting an integral structure with each other, and then heat the road sheet 1 as a whole with medium heat.

(7) The 7th step

Referring to FIG. 4(g), when heated as described above, the road sheet 1 sinks as a whole and gradually adheres to the reinforcing material 500. At this time, only the display portion 12 of the heated road sheet 1 is added. Glass beads 13 are further sprayed, and sand 14 is sprayed on the background portion 11 and the display portion 12, and then the road sheet 1 is heated and fused so that it adheres completely to the reinforcing material 500. .

At this time, as the heat of the road sheet 1 is transferred to the cured sealant 300, the sealant 300 changes to a liquid state again, and as a result, the road sheet 1 and the reinforcing material 500 change to a liquid sealant 300 and the primer 600 to form an integral structure while being more firmly bonded.

After the additional spraying of the glass beads 13 and the sand 14 is finished, fine holes 11a and 12a are formed in the background portion 11 and the display portion 12 of the road sheet 1 using a needle (not shown). form

As an example, when materials such as water vapor are discharged from the road surface 100 due to geothermal heat in summer while the road sheet 1 according to the present invention is installed on the road surface 100, the road sheet 1 ) is likely to be excited.

Accordingly, in the case of this embodiment, when fine holes 11a and 12a are formed from the surface of the background part 11 and the display part 12 to the road surface 100 using a needle (not shown) in the construction process, problems can be minimized.

For reference, the needle punching machine (not shown) is a well-known fine punching device in which countless needles are coupled to the lower part of the main body of the flat plate.

In the case of this embodiment, the fine holes 11a and 12a are shown and described as being formed in both the background part 11 and the display part 12, but this is only one embodiment, and the background part as necessary. (11) or the display portion 12 may be formed only in either one of the fine holes.

When the formation of the fine holes 11a and 12a in the background part 11 and the display part 12 is completed, the background part 11 and the display part 12 are hardened for a certain period of time. Fixing mechanisms 20 and 20' are driven into the display unit 12 to be fixed to the road surface, and the background unit 11 and the display unit 12 are fixed to the road surface through this.

On the other hand, if necessary, when spraying the glass beads 13, known luminous glass beads may be sprayed.

That is, construction of the road sheet according to the present invention is completed through a series of processes as described above.

According to this embodiment, the adhesive 200, the sealant 300, the reinforcing wire 400, the reinforcing material 500, the primer 600, and the road sheet 1 are all integrated into one structure on the road surface 100. Therefore, even if the load of a passing vehicle acts on the road sheet 1, it is possible to increase the resistance to absorb and alleviate expansion, vibration, and deformation of the load displacement, thereby greatly reducing the risk of damage.

In addition, in the case of the conventional method that is directly fused to the road surface, the state of the road surface is displayed on the sheet as it is, and the beauty of the first sheet is lost. The state of the road surface is not exposed, and it can be fused to the road surface while maintaining the beauty of color and appearance at the time of initial sheet production.

In addition, since the glass beads 13 were additionally sprayed only on the display portion 12 of the road sheet 1 on which construction was completed, when the light from the headlights of the vehicle is projected to the background portion 11 and the display portion 12, the background portion The display unit 12 reflects relatively more light than the display unit 11 (11), whereby the distinction between the background unit 11 and the display unit 12 becomes clear. Since it is relatively more prominent and the discrimination is improved, the vehicle driver can quickly recognize the information displayed on the road through the raised display unit 12, and in particular at night or in rainy weather, the information transmission effect can be maximized through greater discrimination will be.

Moreover, since the glass beads 13 protrude from the surface of the display unit 12 to form a concavo-convex shape, the display unit 12 made of white, yellow, orange, etc., which is easy to stain, is installed on a road with high traffic frequency However, the contact area between the surface of the display unit 12 and the vehicle (or pedestrian) can be minimized by the concave-convex glass beads 13, thereby significantly reducing the occurrence of stains. As the surface friction can be increased, even if the surface is wet, the risk of safety accidents such as a pedestrian or vehicle slipping and falling or an increase in the braking distance can be significantly reduced.

Furthermore, surface friction can be increased by the additionally sprayed sand 14, so even if the surface is wet, the risk of a safety accident such as a pedestrian or vehicle slipping and falling or an increase in the braking distance can be significantly reduced.

In addition, the sheet can be firmly fixed to the road surface through the medium of the fixing mechanisms 20 and 20' that penetrate the seat and are embedded in the road surface. It is very useful because it can discharge, and by forming a barrier film 26 on the flow path 21a, the problem of foreign matter from the outside flowing into the flow path 21a and blocking the flow path 21a can be fundamentally solved. there is

In addition, even if substances such as steam are discharged from the road surface 100 due to geothermal heat in summer, the substances are naturally discharged through the fine holes 11a and 12a formed in the background part 11 and the display part 12, so that the road surface 100 It is possible to fundamentally solve the problem of the structure including the road sheet (1) falling or lifting the corresponding part, and moreover, it is possible to significantly reduce the frequent repair work due to the improvement of the lifting problem, thereby reducing cost and eliminating waste of manpower. Side effects that can be done can also be expected.

Although the present invention has been described in detail only for the specific embodiments described, it is natural for those skilled in the art that various modifications and variations can be made within the scope of the technical idea of the present invention, and it is natural that such variations and modifications fall within the scope of the appended claims. .
