Lane-integrated road sign and construction method using the same {Lane-integrated road sign and construction method using the same}

The present invention relates to a lane-integrated road sign and a construction method using the same. More specifically, it relates to a problem in which a road sign made of conventional metal material may come off or break away and damage the tire, resulting in a secondary traffic accident. It is about a lane-integrated road sign and a construction method using the same to improve the problem of high construction costs due to expensive equipment and manpower being used to drill the road floor and then fixing and attaching the road sign with mortar.

Among the problems with paint-type road markings, road studs reinforce road markings to compensate for paralysis caused by reduced visibility, especially at night and in rainy weather, and promote traffic safety and smooth communication by clearly guiding the driver's line of sight. It is a facility installed on the road surface for this purpose.

On our country's roads, lanes often disappear and become invisible due to rain or snow when driving at night. In this environment, diffuse reflections on the road caused by street lights, traffic lights, and headlights of cars in the opposite lane make it more difficult to distinguish between lanes of visibility. do.

In particular, among traffic accidents that occur when existing road signs are installed, accidents involving crossing the center line of the road are caused by driver's negligence such as illegal overtaking, speeding, and drowsy driving, and the lack of traffic safety facilities and poor facilities in the median.

Additionally, traffic accidents at night tend to increase when road lighting is inadequate, and accidents in which vehicles cross the center line or veer off the road mainly occur due to the lack of eye guidance.

In particular, in bad weather such as rainy days, it is very difficult to secure visibility when driving on the road, which poses a risk of causing a major traffic accident. This is because the retroreflective function of road surfaces such as lanes and center lines is not functioning properly.

Therefore, road signs require durability, bending resistance, impact resistance, and elasticity that are visible to the driver's eye regardless of changes in day or night and weather, and are not damaged even when strong impacts or severe changes in surrounding temperature occur.

The structure of road signs stipulates that the height of the sign, that is, the height from the bottom (bottom ground) of the sign body to the top, should be a maximum of 30 mm or less, and should be a height appropriate for field conditions.

In particular, it is recommended that the height not exceed 20 mm in places where traffic between cars is allowed, such as along lane boundaries, and friction between the sign and tires is frequent, and the use of adhesive road signs without anchors is recommended.

Meanwhile, most proposed patent technologies, including the road sign for lane marking in Republic of Korea Patent Publication (B1) No. 10-1856842 (20180511), are of the prop type, which is fixed by driving a prop (or anchor) into the road floor at a certain depth. The perforation method is mainly used, in which the road floor is drilled into a circular shape and then fixed with mortar, etc.

The pole-type road sign has a high height and a rectangular structure. After installation, it is easily pulled out due to frequent shaking due to the friction between the body of the road sign and the vehicle tire, or the sign is frequently damaged when the direction of installation is rotated, so it falls on the road and gets stuck in the tire, resulting in secondary damage. Because they often cause traffic accidents, the National Police Agency recommends that they cannot be installed on road lane boundaries.

In addition, the perforation type requires expensive drilling equipment and manpower to drill into the road bed to a certain depth, insert a marker, and then fix it with mortar, so installation costs are high, and after installation, concrete or asphalt is required due to the perforation. It has been pointed out as a problem that deforms the structure and encourages cracking and settlement.

Korean Patent Publication No. 10-1856842, title of invention “Road sign for lane marking” (2018.05.03.)

The present invention was created to solve the above problems, including the problem that road signs made of conventional metal may come off or damaged tires damage tires and cause secondary traffic accidents, and that expensive equipment and The purpose is to provide a lane-integrated road sign and a construction method using the same, which can improve the problem of high construction costs by mobilizing manpower to drill the road floor and then fixing the road sign with mortar.

In order to achieve the above object, the lane integrated road sign according to an embodiment of the present invention includes a road adhesion portion, a road sign portion attached at predetermined intervals along the longitudinal direction of the road adhesion portion, and a slope groove on one side of the road sign portion ( A reflective portion adhered to the groove, and a polyurea portion integrally applied to the road adhesion portion and the road sign portion,

The road sign has a streamlined square pyramid shape forming a gently sloping surface, has a friction coefficient of 4 or more on the bottom surface, and is characterized by digging into the road contact portion along the edge of the bottom surface.

According to the present invention, there is an advantage that there is no need to damage the road surface like in the conventional prop system because the road sign is attached on the road contact part like planting a seedling.

In addition, the road sign part is made of an elastic material, which has the advantage of reducing the impact of contact with vehicle tires, thereby ensuring road traffic stability by preventing facility departure and secondary traffic accidents.

In addition, since the specific gravity of the road sign increases from the top to the bottom, not only its own weight but also the load is concentrated on the floor, which has the advantage of improving adhesion to the road surface.

In addition, the road sign has a structural feature of having relatively high edges and digging into the road contact area, which has the advantage of improving the bonding force with the road contact area.

In addition, since the polyurea part coats and surrounds the road adhesion part and the road sign part as a whole, there is an advantage of improving sturdiness and suppressing separation from the road surface.

It's a degree.

Referring to the above drawings, the lane integrated road sign 100 according to an embodiment of the present invention includes a road contact portion 110 forming a lane, and a predetermined interval along the longitudinal direction of the road contact portion 110. The road sign part 120 attached to the road sign part 120, the reflective part 130 glued to a groove on one side of the road sign part 120, and the road adhesion part 110 and the road sign part 120 are integrated. It includes a polyurea part 140 that is bonded while stacking, and the road sign part 120 has a streamlined square pyramid shape forming a gently sloping surface, the friction coefficient of the bottom surface 121 is 4 or more, and the bottom surface 120 has a friction coefficient of 4 or more. It is characterized by digging into the road contact portion 110 along the edge 123.

In addition, the road sign portion 120 is made of a mixture of natural rubber (NR) and EPDM (Ethylene-Propylen Diene Monomer), and is characterized in that the specific gravity increases from the top to the bottom.

In addition, the road adhesion portion 110 is characterized in that it is formed by melt spinning with a spinning solution in which glass beads are mixed with one or more polymer resins selected from polyester, polyamide, polyacrylic, polyolefin, and rayon.

In addition, the reflection portion 130 contains gold, silver, copper, aluminum, nickel, chromium, platinum, iron and silicon based on 100 parts by weight of one or more base resins selected from acrylic resin, urethane resin and epoxy resin. It is characterized in that it contains 1 to 50 parts by weight of plate-shaped particles containing one or more metals selected from.

In addition, the polyurea portion 140 is characterized in that it is obtained by creating a chemically stable urea bond through polymerization of isocyanate, the main component, and amine, which produces an ultra-fast curing reaction.

Now, the configuration and function of the lane integrated road sign 100 according to an embodiment of the present invention will be described in detail as follows.

As shown in FIG. 1, the lane integrated road sign bottle 100 proposed in the present invention includes a road adhesion portion 110, a road sign portion 120, a reflection portion 130, and a polyurea portion 140 forming a lane. ) may include.

As shown in FIGS. 1 and 2, the road adhesion portion 110 is melted with a spinning solution in which glass beads are mixed with one or more polymer resins selected from polyester, polyamide, polyacrylic, polyolefin, and rayon. It can be formed by radiation.

The road adhesion part 110 is a kind of buffer part to increase the adhesion between the road sign part 120 and the pavement, which will be described later, and at the same time prevent distortion and cracks due to differences in thermal expansion coefficient, etc., and is used to prevent unevenness of the pavement, separation of aggregates, and concrete pavement. If the condition of the pavement, such as tinting, is not good, it is difficult to secure the coating thickness, and if cracks occur on the construction road surface, or the lane may be distorted due to the difference in the thermal expansion coefficient described above, this is to prevent this.

The road adhesion portion 110 is formed by applying a liquid polymer resin or asphalt composition to the pavement using an adhesive, then placing it and pressing it, or by impregnating it with a polymer resin or asphalt composition to be described later to increase adhesion to the pavement. It can also be attached by heating in the lane position. For this purpose, it is desirable to have a woven or non-woven fabric form rather than a general sheet form so that a certain amount of voids are formed inside.

For this purpose, it is recommended that the road contact portion 110 be formed based on a spinnable polymer resin, and additionally, glass beads may be mixed into the spinning solution to further increase retroreflectivity.

The polymer resin that makes up the road adhesion portion 110 can be of any type as long as it can form fibers through spinning. In particular, it can be used without limitation as long as it can be manufactured from either woven or non-woven fabric and can form voids inside the layer. .

Examples of the above polymer resins include polyester, polyamide, polyacrylic, polyolefin, and rayon. In addition, aromatic polyamide, polyimide, polybenzoxazole, polybenzimidazole, etc. are used to further increase mechanical properties. Polymer resin for high-strength fibers can also be used.

The glass bead is added to further increase the suboptimal retroreflectivity, and preferably has a spherical structure so that diffuse reflection and retroreflection can occur in various directions when irradiated.

In this case, a reflection effect appears in all directions, and at the same time, when mixed with the spinning solution, the flowability of the solution is not impaired, so the quality of the spun fiber can be maintained uniformly.

The average particle diameter of the glass beads is not limited, but is preferably 10 to 50㎛. If the average particle diameter is less than 10㎛, the retroreflection and omnidirectional reflection effects are excellent, but it is not economical, and if the average particle diameter is more than 50㎛, it may affect the flowability of the spinning solution and reduce the mechanical properties of the fiber.

It is recommended to add 1 to 30 parts by weight of the glass beads based on 100 parts by weight of the spinning solution that forms the fiber. If added below the above range, the retroreflective effect may be reduced, and if added above the above range, single yarns of the fiber may frequently occur.

In addition, the thickness of the road contact portion 110 is not limited, but it is recommended to maintain a thickness of 0.5 to 20 mm in order to effectively block heat between the pavement and the recognition layer.

The road adhesion unit 110 first cleans the part of the pavement surface that will form a lane to remove foreign substances from the road surface, then applies a liquid polymer resin or asphalt composition to the pavement using an adhesive, and then forms the road adhesion unit 110. You can attach it by placing it and pressing it, or you can impregnate the road adhesion portion 110 in polymer resin or asphalt and attach it to the surface of the pavement again, and then apply heat to it to develop adhesiveness.

To this end, the road adhesion portion 110 can be impregnated with a polymer resin to develop adhesiveness. At this time, the polymer resin can be used without limitation as long as it is a polymer resin commonly used in the industry, and more preferably, it contains methyl methacrylate (MMA).

The methyl methacrylate contains a vinyl group and exhibits high elasticity properties, and is a widely used material, especially in the reinforcement method of asphalt pavement.

More specifically, it is better to use MMA resin with high elasticity as the polymer resin. The high-elasticity MMA resin is a synthetic resin obtained by adding PMMA, Butyl Acrylate, and an inorganic binder to MMA, and contains 40 to 55% by weight of MMA (Methyl Methacrylate), 15 to 28% by weight of PMMA (Polymethyl Methacrylate), and 15 to 28% by weight of Butyl Acrylate. , when mixing 0.1 to 2% by weight of inorganic binder, the bonding power with the asphalt mixture is excellent, complete curing is possible within 1 hour, and physical properties such as durability, chemical resistance, abrasion resistance, and UV stability are excellent, making it suitable for aggregates. It has the characteristic of effectively suppressing the occurrence of scattering or cracks.

Conventional general MMA resin begins curing by adding a small amount of hardener, approximately 2 to 5% of the resin amount. It is an ultra-fast hardening resin that completely cures within 1 hour after starting curing, and the normal working time is about 20 minutes. Due to its excellent workability, laying and finishing can be performed on a large area.

Although this MMA resin has excellent strength after curing, it not only lacks crack resistance and bending resistance, but also has different thermal expansion characteristics from the base material, so when used outdoors rather than indoors, cracks may occur and the fiber layer may peel off from the construction object. The downside is that it can easily occur.

However, the high-elasticity MMA resin can overcome the above-mentioned disadvantages of the conventional MMA resin by adding PMMA, butyl acrylate, inorganic binder, etc. to the MMA resin.

In addition, the road adhesion portion 110 can develop adhesiveness by liquefying modified asphalt with a high softening point and then impregnating it with it for a certain period of time. Specifically, the high softening point modified asphalt can be made by mixing natural asphalt with a polymer resin and filler.

The natural asphalt is refined from solid asphalt produced in Trinidad, Canada, and has a penetration degree of 1 to 4 (1/10 mm) and a softening point of 93 to 98°C. It increases softening point, increases toughness, wear resistance, impact resistance and Cold resistance can be improved.

The polymer resin is preferably a thermoplastic resin or thermoplastic elastomer, and is added to adjust high temperature fluidity, increase heat resistance, and improve elasticity and adhesion. Examples of such polymer resin include polymethylmethacrylate, Polystyrene, polybutadiene, polyethylene, ethylene-butencopolymer, ethylene-octene copolymer, etc. are used alone or in a mixture of two or more. You are free to use it.

The filler is mainly added to improve the heat resistance and mechanical properties of the composition. Examples of such fillers include waste tire powder, blast furnace slag powder, carbon black, and vermiculite. These fillers can be used alone or in a mixture of two or more. It's also good.

The modified asphalt may contain 50 to 100 parts by weight of polymer resin and 10 to 50 parts by weight of filler relative to 100 parts by weight of natural asphalt, and if necessary, additional substances such as crosslinking agents, antioxidants, and softening point increasers can be added. .

The road adhesion portion 110 can be formed by impregnating the modified asphalt as described above, attaching it to the pavement surface, and fixing it by applying heat. At this time, the heat applied to the road adhesion portion 110 is not limited in the present invention, but it is preferable to sufficiently heat the modified asphalt at a temperature of 150 to 200°C until it softens and then cool it to harden it.

As shown in FIGS. 1 to 4, the road sign unit 120 has a structure that adheres to the road surface by forming a streamlined hill like a gentle ridge on a flat bottom surface.

As shown in FIGS. 1 and 2, the road sign part 120 proposed by the present invention is a plurality of members attached at predetermined intervals along the longitudinal direction of the road adhesion part 110.

That is, as shown in FIG. 3, the road sign unit 120 has a streamlined square pyramid shape forming a gently sloping surface, the friction coefficient of the floor surface 121 is 4 or more, and the road sign unit 120 has a friction coefficient of 4 or more along the edge 123 of the floor surface. It is characterized by digging into and being closely adhered to the road contact portion 110.

Here, the road sign part 120 is made of natural rubber (NR), etc., so that the bottom surface has a friction coefficient of 4 or more to assist in being integrated with the road adhesion part 110, and is resistant to external shock or pressure. Restrain it from being easily pushed off by the back.

In addition, since the road sign part 120 is not made of metal, it will not damage the tires of a running car even if damaged, and is made of a mixture of natural rubber (NR) and EPDM (Ethylene-Propylen Diene Monomer) that is cushioning and resistant to heat and cold. It has high durability due to the structural advantages of the streamlined square pyramid shape with a height of 20mm, a width of 70mm, and a length of 100mm, and the specific gravity increases from the top to the bottom, so the center of gravity is closer to the road floor than the existing invention. It can minimize departure from the road and is stable.

In other words, as shown in FIGS. 3 and 4, the road sign unit 120 has a streamlined square pyramid shape with a structure in which the proportion increases from the top to the bottom, and is shown in an exaggerated form compared to reality for easy understanding. A relatively high specific gravity is concentrated at the edge of the floor surface 123 and penetrates into the road contact part 110 to improve adhesion with the road contact part 110.

The reflector 130 is a member adhered to a groove on an inclined surface on one side of the road sign 120, and is made of gold based on 100 parts by weight of one or more base resins selected from acrylic resin, urethane resin, and epoxy resin. , it may contain 1 to 50 parts by weight of plate-shaped particles containing one or more metals selected from silver, copper, aluminum, nickel, chromium, platinum, iron and silicon.

The reflector 130 has selective light reflectivity and its reflection characteristics vary depending on the time of day, so when mixed irregularly, the reflection characteristics are expressed at any angle, thereby significantly increasing visibility even at night or in rainy weather.

Additionally, the reflective portion 130 is basically formed by including a reflective pigment in a base resin for forming a layer. In this case, the reflective pigment may be a plate-shaped particle containing a metal.

The base resin includes acrylic resin, urethane resin, and epoxy resin, and these can be used alone or in combination of two or more.

The acrylic resin has an acrylic group in the molecule, and can be used without limitation as long as it is a polymer polymerized from an acrylic monomer.

In addition, the production method of the acrylic polymer is not limited, and for example, it may be produced by copolymerizing an acrylic monomer or an acrylic monomer with another monomer.

Diglycidyl ether, normal butyl methacrylate, normal hexyl methacrylate, 2-ethylhexyl methacrylate, cyclohexyl methacrylate, methyl acrylate, propyl acrylate, isobutyl acrylate, normal butyl acrylate, One or more monofunctional or higher acrylic monomers and equivalents such as tertiary butyl acrylate, 2-ethylhexyl acrylate, normal octyl acrylate, isobornyl acrylate, and cyclohexyl acrylate may be included. Among these, methyl methacrylate (MMA) and hydroxypropyl methacrylate (HPMA) are used in terms of mechanical properties such as pot life, drying time, wear resistance, adhesion to substrate, tensile strength, adhesive strength, and bending strength. It is desirable to use

The urethane-based resin can be synthesized using hard segments using glycol and amines, soft segments using polymeric glycol, and polyisocyanate as main raw materials. The synthesis of urethane-based polymers can be done using either the One-Shot method, in which polyurethane glycol and a chain extender admixture and polyisocyanate are reacted at once, or the Prepolymer method, in which an excessive amount of polyisocyanate is reacted and the prepolymer is then chain-extended again. It is synthesized using the method. Polyurethane emulsion has excellent tensile strength, chemical resistance, and abrasion resistance, making it suitable for use in polymers such as elastomers, flexible foams, rigid foams, plastics, paints, adhesives, and synthetic leather. It is used in almost all fields of materials.

The epoxy resin can be used without limitation as long as it is a monomer having an epoxy group. Specifically, the epoxy resin may be an epoxy compound containing one or more epoxidized aliphatic ring groups, an epoxy compound containing one or more glycidyl ether groups, or a compound having at least two epoxy groups and at least one aromatic ring in the molecule. Specific examples of the epoxy include 3,4-epoxycyclohexylmethyl, 3,4-epoxycyclohexane carboxylate, bis(3,4-epoxycyclohexylmethyl)adipate dicyclopentadiene dioxide, limonenedioxide, and 4-vinylcyclohexenedioxide, 1,4-cyclohexanedimethanol diglycidyl ether, novolac epoxy, bisphenol A-based epoxy, bisphenol F-based epoxy, brominated bisphenol-based epoxy, 1,6-hexanediol digly.

The plate-shaped particles are basically formed of a material that has the property of reflecting light, but are added to further increase the probability of reflecting light in various directions by increasing the area that receives or reflects light compared to spherical particles. Any reflective material that can be formed into a plate shape can be used. Examples of such reflective materials include gold, silver, copper, aluminum, nickel, chromium, platinum, iron, and silicon, and these may be used alone or in combination of two or more.

The size of the plate-shaped particles is not limited. Basically, it is good to have a desirable size within a range that does not deteriorate compatibility with the base resin, for example, a thickness of 0.1 to 1㎛ and a length of the longest side of 1 to 5㎛.

It is preferable to add 1 to 50 parts by weight of the plate-shaped particles based on 100 parts by weight of the base resin. If added below the above range, light reflectance may be reduced, and if added above the above range, extreme diffuse reflection may cause significant fatigue to the driver's eyes.

Since the reflective layer is basically formed of a thermoplastic or thermosetting base resin, it can be formed by directly applying the method of curing the thermoplastic or thermosetting resin as described above. Specifically, it can be formed by applying heat to the composition forming the reflective layer or mixing it into a liquid state and then applying it to the surface of the fiber support layer. At this time, the formation thickness of the reflective layer is not limited, but it is good to have a thickness of 1 to 5 mm.

The polyurea part 140 is formed by stacking and combining the road adhesion part 110 and the road sign part 120, and is a polymerization reaction of isocyanate, which is the main substance, and amine, which creates an ultra-fast curing reaction. ) can be obtained by creating a chemically stable urea bond.

As a result, after the subject and subtitle are applied to the upper surface of the road adhesion portion 110 and the road sign portion 120, adhesion and curing are achieved quickly.

The temperature of the main and sub-subjects can be selectively adjusted according to the specific gravity and concentration of the two and the situation of the additive, and can also be adjusted according to the degree of curing of the applied polyurea portion 140.

The polyurea portion 140 proposed in the present invention is obtained by creating a chemically stable urea bond through the polymerization of isocyanate, the main material, and amine, which produces an ultra-fast curing reaction, and is generally used as a rust preventive.

1. First preparation step (S110)

Prepare the road contact part 110 by referring to the information described above.

Here, the road adhesion portion 110 may be formed by melt spinning with a spinning solution in which glass beads are mixed with one or more polymer resins selected from polyester, polyamide, polyacrylic, polyolefin, and rayon.

2. Compression step (S120)

This is the step of painting and pressing the prepared road adhesion portion 110 so that it is firmly seated on the road surface to be constructed.

Here, if the prepared road adhesion portion 110 is in a liquid state, it can be sprayed and painted on the road surface, or if it is in a solid state rather than a liquid state, it can be directly attached to the road surface and fused with high heat.

3. Second preparation step (S130)

As shown in FIG. 3, this is the step of preparing a road sign 120 in the shape of a square pyramid.

Here, the road sign part 120 is prepared in advance so that a groove, which is a space where a reflecting part 130 described later can be attached, is formed on one side of a gentle slope.

4. Third preparation step (S140)

This is the step of preparing the reflector 130.

At this time, the reflection unit 130 is made of gold, silver, copper, aluminum, nickel, chromium, platinum, iron, and silicon for 100 parts by weight of one or more base resins selected from acrylic resin, urethane resin, and epoxy resin. It contains 1 to 50 parts by weight of plate-shaped particles containing one or more metals selected.

Additionally, the reflector 130 may be prepared in a configuration that is easily attachable and detachable from the groove of the road sign unit 120. In other words, it can be supplied by cutting it to fit the size of the number produced to a predetermined thickness through a separate process.

5. Adhesion step (S150)

In the step of adhering the reflector 130 to the groove of the road sign 120, the reflector 130 can be attached by pressing it with a predetermined pressure using press equipment, or the cut reflector 130 can be adhered using double-sided tape. It may be possible.

6. Fourth preparation step (S160)

This is a coating step to ensure that the road adhesion portion 110 and the road sign portion 120 can be firmly bonded within a day, so that they are integrated so that they are not easily separated by external forces generated from the surrounding environment (rain, snow, wind, cars, etc.). This is the step of preparing the polyurea portion 140 so that it can be combined.

Here, the polyurea portion 140 can create a chemically stable urea bond through polymerization of isocyanate, the main component, and amine, which produces an ultra-fast curing reaction.

7. Integration step (S170)

Finally, as a final step of integrally combining the road adhesion portion 110 and the road sign portion 120 embedded in the road adhesion portion 110, the polyurea portion 140 is connected to the road adhesion portion 110 and the road. This is a step in which the surface of the cover 120 is painted to a predetermined thickness to maintain integrity and increase bonding strength.

As such, the lane integrated road sign and the construction method using the same according to an embodiment of the present invention can be expected to have the following effects.

According to the present invention, the road sign part 120 is attached on the road adhesion part 110 as if planting a seedling, so there is an advantage that there is no need to damage the road surface like a conventional prop type.

In addition, the road sign unit 120 is made of an elastic material, which has the advantage of ensuring road traffic stability by reducing the impact of contact with vehicle tires and preventing facility separation and secondary traffic accidents.

In addition, since the specific gravity of the road sign unit 120 increases from the top to the bottom, not only its own weight but also the load is concentrated on the floor, which has the advantage of improving adhesion to the road surface.

In addition, the road sign portion 120 has the advantage of improving the bonding force with the road adhesion portion 110 due to the structural feature that the edges 123 are relatively high in weight and penetrate into the road adhesion portion 110.

In addition, since the polyurea portion 140 integrally coats and surrounds the road adhesion portion 110 and the road sign portion 120, there is an advantage of improving sturdiness and suppressing separation from the road surface.

In addition, unlike the conventional drilling type, it does not drill concrete or asphalt road surfaces, so it has the advantage of being very simple to install and construct without expensive drilling equipment or manpower.

In addition, there is no road deformation due to road subsidence or cracks due to perforation after installation of the facility, and there is an advantage in significantly reducing costs due to reinstallation and road damage after facility removal.

In addition, the road sign unit 120 is made of an elastic material containing natural rubber, which has the advantage of preventing the road sign from being damaged by greatly alleviating the shock resulting from contact with vehicle tires.
