{Road signal and installation method thereof}

More particularly, the present invention relates to a road marking apparatus for an attaching road, and more particularly, it relates to a road marking apparatus for attaching road markers, in which concrete or asphalt road surface is directly attached to a road by an adhesive without perforating the road, And more particularly to an adhesive type road marking which is short in solidification time and excellent in adhesive strength.

A road sign is a device that is installed in a lane in a car, reflects light received from a vehicle, and reflects it to a driver or a driver of a vehicle or the like to a pedestrian around the road.

Such a road marker has a reflector that reflects light, thereby providing visibility to the driver of a vehicle or a pedestrian around him / her with information about a curve of a lane and a road with high visibility so that a driver or a pedestrian of the vehicle can move more safely .

In addition, a large number of lanes are installed on the lane, and the lane is protruded to the upper part of the road surface. Therefore, when the lane exceeds the lane, the wheels of the vehicle exceed the road markers.

However, such road markers may be exposed to various external environments on the road surface after being installed, which may cause discoloration or reflex reflection performance of the reflector to deteriorate.

In addition, since it is exposed to the outdoors, it is likely to be contaminated with various pollutants, and thus there is a problem that the reflector may be covered with the pollutant.

In addition, there is a problem that the main body or the reflector is damaged due to an external impact caused by a vehicle or the like.

Furthermore, in the case of road markers installed using commonly used fixed pillars, if the original function is lost due to rotation of the road markers about the fixed pillars, or when the road markers are separated from the road surface due to the loss of the fixed- There is a problem in that there is a high risk of occurrence of secondary accident such as penetration of the stock tire.

In addition, in order to install the road markers using the fixing pillar, there is a problem that a complicated installation method such as drilling a hole for inserting the fixed paper stock on the road surface is required.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention or precedent of the user. Therefore, the definition should be based on the contents throughout this specification.

In the description of the present invention, the same or similar elements are denoted by the same or similar reference numerals, and a detailed description thereof will be omitted.

1 to 8, the construction of the first embodiment of the stick-on road marker according to the present invention will be described in detail.

1 to 5, a first embodiment of an attachable road marker according to the present invention comprises a base part 100, a recessed surface (not shown) provided on a side surface or an upper surface of the base part 100 And reflectors 200 provided on the depressed surfaces 114 and 116 for retroreflecting the light.

The base portion 100 is a constituent element that forms the overall shape of an attachable road marker according to the present invention and is a main body that is coupled to a reflective portion 200 described later.

Since the attachable road marker according to the present invention is installed on the road so that the vehicle may pass over to the upper part of the sticker road marker according to the present invention, the road marker may be formed in such a way as not to hinder the passage of the vehicle or damage the vehicle It is advantageous.

In this embodiment, the base portion 100 is formed of polycarbonate to withstand an external impact, but the shape and configuration of the base portion 100 are not limited as long as the base portion 100 can withstand an external impact caused by a vehicle or a snow removal operation. have.

The base 100 may have a projection 101 or a lattice-like rib 103 formed on the bottom surface thereof. In the present invention, it is preferable to improve the adhesive force through the protrusions 101 or the lattice-like ribs 103 because the road surface is not punctured and fixed with an adhesive without a fixing post.

In addition, the base portion 100 has an inner hollow shape and an adhesive is introduced into the base portion 100, thereby maximizing the adhesive force.

In addition, the base portion 100 may be coated with a coating using a nano coating technique on the outer surface to reduce damage due to moisture, ultraviolet rays, and impact.

The reflective portion 200 is a sheet-shaped component provided on the depressed surfaces 114 and 116 or the upper surface of the base portion 100 and retroreflecting the light.

The reflected light passes through the cover 300 The color of the cover part 300 can be seen as a desired color.

With this configuration, there is an effect that the color of the reflection part 200 does not change the retroreflective performance, and the color of various reflected light can be applied with a certain performance.

Particularly, the blue reflector has a disadvantage in that the reflectance of the blue reflector is lower than that of the white or yellow reflector, which is generally applied to road markers. Therefore, in case of a blue road sign used for a bus lane or a highway lane of a toll gate, There were many cases that had to be used.

However, if the desired color is adjusted through the color of the cover part 300 as in the present embodiment, it is possible to provide a road marker capable of reflecting light of a sufficient brightness in various colors inexpensively and easily.

Also, since the cover portion 300 is formed to protect the reflection portion 200, the reflection brightness of the reflection portion 200 is relatively long, thereby extending the service life of the road marker.

Meanwhile, the cover part 300 may be provided with a diffuse reflection protrusion 301 to refract the light reflected by the reflection part 200 irregularly, and may have a pyramid shape, but the present invention is not limited thereto.

8 and 9, the construction of the second embodiment of the stick-on road marker according to the present invention will be described in detail.

The second embodiment of the sticky road marker according to the present invention may include the base part 100 and the reflection part 200 like the first embodiment described above, The detailed description thereof will be omitted.

However, in the third embodiment of the attachable road marker according to the present invention, the reinforcing ribs 105 are formed in the base part 100 to improve the adhesion and durability. The reinforcing rib may extend from a grid-shaped rib provided on a bottom surface of the base portion.

In addition, the diffusive projection 301 may be formed on the reflecting portion 200a on the upper surface of the base portion 100 as well.

In this case, the pedestrian may recognize the road markers, or the sticky road marker according to the present invention may be installed on the inner wall surface of a facility such as a tunnel or the like.

Especially, it is applied to a bicycle-dedicated road such as a park, and reflection of the light of a street lamp to a bicycle driver or a pedestrian around can be used to prevent a safety accident.

The shape and configuration of the reflective portion and the depressed surface are not limited as long as the reflective portion and the depressed surface are configured to be capable of variously refracting and reflecting light.

Further, the performance of the above-described mountable road markers on the brightness and range of the retroreflective reflection of the road markers can be improved, so that the attention of the driver and the like of the vehicle can be attracted more efficiently and various incidents can be prevented have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a method of installing an attachable road marker according to the present invention will be described with reference to the accompanying drawings.

10, the method for installing the sticky road marker 1 according to the present invention includes a positioning step S100, a perforating step S200, a surface processing step S300, a bonding step S400, and a cleaning step S400. (S500).

The position designation step S100 is a step of designating a position where a plurality of road signs 1 are installed along the road and displaying the position thereof in advance. In general, the road marking device 1 is a lane on the road surface, , Both side portions, and wall surfaces inside the tunnel.

Further, it is advantageous to install the vehicle in a position where it can be recognized more easily in order to draw the driver's attention to the curved road section where the road is broken.

A plurality of sticky road markers 1 are arranged at regular intervals at regular intervals to guide the driver, and at a point where the driver should pay more attention, It is possible.

In this way, the mounting position of the marker-type road marker 1 can be determined according to the surrounding conditions and the like, and its position can be displayed in advance to prepare for installation.

The perforating step S200 is a step of forming the perforation hole 400 by perforating the place where the preprinted road marker 1 is installed in a form corresponding to the shape of the sticky road marker 1.

As shown in FIG. 11, in the present embodiment, in order to fix the marker-type road marker 1 more firmly, A circular perforation hole 400 may be formed in the place where the road marker 1 is installed according to the shape of the circular attachment road sign 1.

As shown in FIG. 12, at a position indicated in the above-described position designation step S100, the position where the attachable road marker 1 is installed is punctured to a predetermined depth through a separate perforator 500, A perforation hole 400 into which the road marker 1 is inserted can be formed.

In this embodiment, the perforator 500 is configured to rotate by using the perforator 500 of the shape corresponding to the shape of the sticky road marker 1. However, in the case where the sticky road marker 1 has a polygonal shape, The drill hole, and the drill hole, the drill hole 400 may be inserted into the drill hole 400, and the drill hole 400 may be inserted into the drill hole 400, .

Subsequently, the surface machining step S300 is a step of machining the inner surface of the perforation hole 400 so that the inner surface of the perforation hole 400 is adhered with the attaching road marker 1 with stronger bonding force.

13 and 14, an embodiment of the method of installing an attachable road marker 1 according to the present invention includes a step S300 of cutting an inner surface of a perforation hole 400, The cutting groove 410 can be formed.

A plurality of cut grooves 410 are formed in various directions on the bottom surface and the side surface of the inner surface of the perforation hole 400 to form various irregularities in the perforation hole 400, The frictional force between the road markers 1 is increased and the contact area between the adhesive 600 and the inner surface of the perforation hole 400 applied in the bonding step S400 described later is increased, It is possible to provide a stronger bonding force between the marker 1 and the marker 1.

Particularly, the cut groove 410 shown in FIG. 14 may be formed in a partially protruded form of the perforated surface of the perforator 500 and may be formed naturally in the perforation process, You can also get a reduction effect.

Of course, if the cut groove 410 formed on the inner surface of the perforation hole 400 is provided to increase the friction between the road mark name and the inner surface of the perforation hole 400, the shape and size of the cut groove 410 may be various without limitation.

15, another embodiment of the surface machining step S300 may form the plurality of cut grooves 410 in a direction that is at a predetermined angle with the traveling direction 700 of the vehicle.

In the case where the attachment road markers 1 are installed on the road surface, the vehicle may proceed while pressing the attachment road markers 1, thereby causing many impacts to be transmitted to the attachment road signs 1, The indicator 1 may be released.

At this time, since the direction in which the attachable road marker 1 is impacted is the traveling direction 700 of the vehicle, a plurality of cut grooves 410 are formed on the inner surface of the perforation hole 400, The frictional force between the inner surface of the perforation hole 400 and the sticky road marker 1 is increased so that even when the sticky road marker 1 is impacted by the vehicle in the traveling direction 700 of the vehicle, There is an effect that it can be prevented from being separated.

16, in the surface machining step S300, the bottom surface of the inner surface of the perforation hole 400 is raised upward in the traveling direction 700 of the vehicle to prevent the above- The perforation hole 400 may be machined so as to have an angle.

At this time, the bottom surface of the road sign 1 is formed in a shape corresponding to the shape in which the bottom surface of the perforation hole 400 is processed to have an upward angle in the traveling direction 700 of the vehicle, ). ≪ / RTI >

In this case, since the direction of the impact transmitted to the attachable road marker 1 by the vehicle is close to perpendicular to the bottom surface of the perforated hole 400 processed to have a slope, There is an effect that the attachable road marker 1 can be prevented from being detached.

Further, in addition to the above-mentioned process, if the friction between the insertion marker 1 and the perforation hole 400 is increased and the adhesive force is enhanced to prevent the detachment of the marker 1, can do.

Meanwhile, the surface machining step (S300) may include a process of injecting air into the perforation hole (400).

Through this process, foreign matter such as debris, dust, leaves, and the like, which are generated when the perforation hole 400 is formed in the perforating step S200 or when the cutting groove 410 is formed in the surface processing step S300 So that it is not left inside the perforation hole 400.

The adhesion between the road marker 1 and the perforation hole 400 due to the adhesive 600 may be weakened in the bonding process to be described later when the inside of the perforation hole 400 exists, It is advantageous to remove the foreign matter of the above.

In addition, the surface machining step S300 may include a step of heating the inner surface of the perforation hole 400.

Through this process, foreign matter remaining in the perforation hole 400 may be burned and removed, or the internal temperature of the perforation hole 400 may be increased to prevent the adhesive 600 from being cured too quickly during a bonding process, There is also an effect that can be done.

In addition, it is also possible to prevent a problem that moisture in the perforation hole 400 is removed, and the adhesive performance of the adhesive 600 is lowered due to moisture during the bonding process described later.

In addition to the above-described processes, any process may be performed without limitation as long as it is provided to remove foreign substances in the perforation hole 400, such as by sucking the inside of the perforation hole 400.

17, the bonding agent 600 is applied to the interior of the perforation hole 400, the road marker 1 is inserted into the perforation hole 400, Thereby fixing and coupling the road marker 1 to the inside of the perforation hole 400.

At this time, it is advantageous to insert the road mark bottle 1 into the perforation hole 400 in which the adhesive 600 is applied, and to fix the adhesive 600 so that a minute amount of the adhesive 600 flows out of the perforation hole 400 .

As shown in FIG. 18, a plurality of protrusions and recesses in the form of a depressed inner surface are formed on the lower surface of the sticky road marker 1, so that the adhesive 600 fills the irregularities inside the sticky leaf 1 Can be hardened.

In this case, since the area where the adhesive 600 is fixed in contact with the marker 1 is increased, the performance of fixing the marker 600 to the marker 1 is improved, (1) can be fixed.

The adhesive 600 is also supplied into the plurality of cut grooves 410 formed in the surface processing step S300 described above to increase the friction between the inner surface of the perforation hole 400 and the sticky road marker 1, The contact area between the adhesive 600 and the inner surface of the perforation hole 400 is increased to provide a stronger bonding force between the inner surface of the perforation hole 400 and the adhesive marking marker 1. [

In particular, as shown in FIG. 19, when the adhesive road marker 1 is installed on a road formed of asphalt, the adhesive 600 permeates between the particles of the asphalt and hardens, so that the adhesive road marker 1 is asphalt As shown in FIG.

In addition, when inserting the road marker 1 in the bonding step (S400), it is preferable to install the road marker 1 on the lane, for example, suitable for the place where the road marker 1 is installed It is advantageous to select and install the road mark bottle 1 of the color corresponding to the color of the center line (yellow), the general lane (white), and the bus lane (blue).

In addition, the adhesive 600 used in the present embodiment can be applied by melting the adhesive 600 through heating.

By using the adhesive 600 by fusing it, it can be more easily injected into the cut grooves 410 or between the grains of irregularities or asphalt on the lower portion of the road marker 1 to have improved fixing performance.

For the sake of convenience of use, such an adhesive 600 may be used by being solidified again when the temperature is lowered in a melted state.

Next, in the cleaning step S500, the bonding agent 600 flowing out of the perforation hole 400 and the fragments generated in the perforation step S200 are removed in the bonding step S400, .

If foreign matter such as debris is left, it may cause a safety accident by popping up by a passing vehicle, or it may contaminate the road marking device 1 to reduce the retroreflective performance of the marking road marking device 1, It may be adhered to the adhesive 600 flowing out of the hole 400, so it is advantageous to arrange the construction site.

When the installation of the sticky road mark bottle 1 is completed through the above-described process, the installation mark is displayed in step S100. 1) can be continuously installed.

Through the above process, the mounting road markers (1) can be installed to greatly improve the fixing and coupling performance of the mounting road markers (1), saving the time and effort required for installation and maintenance of the mounting road markers can do.

Further, it is possible to more effectively attract the attention of the driver and the like of the vehicle through the installed road sign 1, thereby preventing various accidents.

In addition, since the location where the road marker 1 is installed is pierced and adhered, there is little fear of breakage or disconnection due to strong fixing performance. In the case of not including a fixing post, A car accident can be prevented and an extremely high safety can be secured.

Hereinafter, the adhesive used for installing the road markers according to the present invention will be described in detail.

The adhesive road markers of the present invention are applied in such a manner that the road markers are adhered to the road surface using an adhesive without inserting pillars or anchors on the road surface. Therefore, in the present invention, a hot-melt adhesive capable of satisfying both adhesive strength, workability and economy of an adhesive is used.

The hot melt adhesive may comprise 10 to 20 parts by weight of wax, 5 to 15 parts by weight of a tackifier resin, and 20 to 50 parts by weight of a filler based on 100 parts by weight of the base resin, and further adding a small amount of a plasticizer and an antioxidant can do.

Examples of the base resin include thermoplastic resins such as ethylene-vinyl acetate (EVA), polyethylene (PE), and polypropylene (PP).

The wax may be paraffin wax or polyethylene wax.

Examples of the tackifier resin include rosin and terpene resins.

Examples of the filler include talcum, calcium carbonate, and the like.

The plasticizer may be polybrene or paraffin, and the antioxidant may be an aromatic amine.

The hot-melt adhesive having such a composition is excellent in adhesion to concrete and asphalt, and is stable against temperature change, so that the adhesive strength is not lowered or the adhesive layer is not broken even at -30 to 60 ° C.

The adhesive force of the hot-melt adhesive is 100 kg / cm 2 or more and is applied in a molten state by heating at 180 to 230 ° C, more preferably 190 to 210 ° C, using an adhesive melter or the like.

If the heating temperature of the hot-melt adhesive is lower than 180 ° C, the solidifying time is accelerated, and the adhesive is liable to cause defective adhesion, the viscosity is increased, the adhesive does not penetrate the road surface, and the adhesive strength is lowered. When the heating temperature is higher than 230 ° C, the viscosity increases and the adhesive flows down, and the chemical structure of the adhesive is changed due to the high heat, resulting in deterioration of the adhesive strength and carbonization, which shortens the life of the melting machine.

The adhesive is applied in a thickness of 2 to 5 mm and works when the external temperature is 5 ° C or higher, more preferably 10 to 30 ° C. When the external temperature is less than 5 ° C, the adhesive strength is lowered because the adhesive surface is hardened. Therefore, when the temperature is below 15 ° C, the melting temperature is increased to 210-220 ° C and the surface is heated with hot air .

In the case of a new road, the road surface is tender and tender, so that the adhesive force may be lowered due to deformation or an external force. Therefore, it is desirable to work after the vehicle has passed sufficiently. Also, in the case of old roads, the surface is uneven due to the influence of abrasion or foreign matter, and it is hardened and broken or broken. Therefore, it is preferable to use the primer before the construction to smooth the road surface or to perform the blasting or grinding work.

On the other hand, the adhesive may be used only as a single component of the hot-melt adhesive, but an adhesive having a thermosetting adhesive added to the hot-melt adhesive may be used.

For example, when sunlight is supplied to the asphalt for a long time in the summer, heat is accumulated inside the asphalt and heated to a temperature significantly higher than the external temperature. In this case, the hot melt adhesive can be softened. If an external force is applied to the softened adhesive due to a collision of the vehicle or the like, the attached road markers may be pushed or the adhesive force may be lowered. Therefore, if a composite adhesive having a thermosetting resin added to a hot-melt adhesive is used, the adhesive strength can be maintained without being softened even at a high temperature.

The adhesive may include a thermosetting adhesive containing 10 to 20 parts by weight of a thermosetting resin based on 100 parts by weight of the hot-melt adhesive and 5 to 10 parts by weight of a curing agent.

The thermosetting resin is epoxy and the curing agent is polyamide. The adhesive strength is improved by the epoxy, and after the curing, it is not melted again so that the hot-melt adhesive is adhered and then softened by heating can do.

The adhesive may be prepared by first heating and melting the hot-melt adhesive, mixing the thermosetting resin thoroughly, and then mixing the hardener immediately before adhering to the road marking bottle, thereby preventing the thermosetting resin from being cured in advance.

When an adhesive mixed with a hot-melt adhesive is used for the hot-melt adhesive as in the present embodiment, the adhesive can be adhered to the road surface directly without forming a hole.

Hereinafter, the physical properties of the adhesive used in the present invention will be described in detail with reference to the following examples.

100 parts by weight of polyethylene resin, 10 parts by weight of paraffin wax, 15 parts by weight of terpene resin, 30 parts by weight of talc, 0.5 part by weight of plasticizer and 0.5 part by weight of aromatic amine are mixed to prepare a hot melt adhesive.

15 parts by weight of an epoxy resin as a thermosetting resin, 10 parts by weight of isopropyl alcohol as a solvent, and 10 parts by weight of a polyimide resin as a curing agent were sequentially mixed with 100 parts by weight of the hot melt adhesive prepared in Example 1 to prepare a composite adhesive.

The adhesive prepared through Examples 1 and 2 was applied on the asphalt surface to a thickness of 5 mm and solidified. The tensile strength and the adhesive strength of the adhesive layer were calculated numerically. The test piece was immersed in an aqueous solution of 50 g / L of H ₂ SO ₄ at room temperature For 24 hours to visually observe the extent of the change in acid action. In addition, the specimens were immersed in an aqueous solution of 50 g / L of NaOH for 24 hours at room temperature to examine the degree of alkalinity (see EN 1279-2) The cycle was maintained for a total of 168 hours with a cycle of 12 hours, followed by visually observing the degree of change. In the acid resistance, alkali resistance and heat resistance repeated test, the state in which the entire surface is peeled off or cracked from the state where the surface is most stable is indicated in the order of?,?,?, And?

As can be seen from the above Table 1, the adhesives of Examples 1 and 2 are excellent in tensile strength, compressive strength and adhesive strength, and in particular, in the chemical resistance and heat resistance repeated test, Which is superior to the hot-melt adhesive.

In addition, the adhesive of Example 2 is inexpensive as compared with the epoxy adhesive, and has an advantage that the thermal property is improved as compared with a general hot-melt adhesive using only a thermoplastic resin.
