Description

Road Sign {Road Stud}

The present invention relates to a road sign bottle, and more particularly, to a road sign bottle with improved installation structure.

Road markers are usually installed at regular intervals along the centerline of the paved road to make it easier for the driver to recognize the centerline. The road sign bottle is composed of a display unit on which a reflector reflected by light is installed, and an anchor extending from a lower portion of the display unit and embedded in a road surface, and manufactured as a standard product meeting predetermined conditions.

The construction method of the road sign disease is disclosed in Clause 5 of the road safety facility installation and management guideline which is jointly managed by the Ministry of Construction and Transportation and the National Police Agency.

According to this, first, the position to install a road sign bottle is determined and a hole (it is called "anchor insertion hole") is drilled. At this time, the depth of the anchor insertion hole is deeper than the length of the anchor of the road sign bottle. Then, after removing impurities such as dirt or oil on the road surface, the adhesive is poured into the anchor insertion hole to raise the position of the road surface.

After the anchor of the road sign bottle is inserted into the anchor insertion hole, the indicator of the road sign bottle is vibrated to allow sufficient adhesive to be applied to the side of the anchor. Thereafter, the adhesive works are left until completely cured, and then the construction work of the road sign bottle is finished by cleaning the leaked adhesive to the outside of the road surface.

However, according to the construction method as described above, the installation time of the road sign bottle has a disadvantage that the construction time of the road sign bottle takes relatively long after the road cover bottle is installed. In addition, in the past, since the installation time of the road sign bottle is long, it is difficult to expect a smooth traffic flow because it takes a long time to control the vehicle movement of the road. Therefore, there is a disadvantage in that the overall distribution cost of the national economy is increased.

In addition, if the location of the center line is changed by expanding the road in the width direction, there is a disadvantage that it is difficult to recycle the existing road cover bottles. That is, when the existing road sign bottle is removed from the road surface mainly due to the adhesive strength of the adhesive used as an epoxy resin, the debris of the broken ascon and the adhesive stick to the road sign bottle. Therefore, it is also a disadvantage that it is not easy to remove the debris of ascon from the road sign bottle and recycle it again.

In addition, there is a problem that the conventional road sign bottle is not environmentally friendly because it uses an epoxy resin, such as a carcinogen during construction.

In addition, conventionally, since the adhesive is required at the time of construction of the road sign bottle, the road sign bottle cannot be constructed in summer and winter. In addition, there is a constraint that road signs cannot be installed even under snow or rain.

On the other hand, the conventional road sign bottle has a problem that the display unit may be rotated with respect to the road surface when the external vibration occurs or the wheel of the car passes on the road sign bottle. If the display part rotates, the installation angle of the reflector is changed, so that the road sign bottle installed to facilitate the center line recognition cannot perform its function for 10 minutes, and if the rotation is frequent, the road sign bottle can be released from the anchor insertion hole. There is a problem that may act as a factor causing accidents.

Accordingly, it is an object of the present invention to provide a road sign bottle which can be easily constructed and also reduces the time required for construction.

Another object of the present invention is to provide an environmentally friendly road sign bottle because it does not use an adhesive such as epoxy resin, which is a carcinogen during construction.

Still another object of the present invention is to provide a road sign bottle that is easy to recycle.

It is still another object of the present invention to provide a road marking bottle which can be easily constructed regardless of construction constraints, including whether the relative humidity level in the air is present or whether the road surface is dry.

Still another object of the present invention is to prevent the road sign bottle from being arbitrarily rotated by external force.

Here, the elastic holding member is coupled to the anchor portion; Extending from the engaging portion may be configured to have a plurality of elastic engaging plate portion disposed in the circumferential direction on the side of the anchor and elastically urged radially outward with respect to the axis of the anchor. At this time, the locking step is formed by the front end of each elastic locking plate.

At least one of the elastic catching plate portions may be formed in a double.

The engaging portion of the elastic retaining member is provided with a press-fit hole in which the anchor is forcibly fitted. At this time, in order to facilitate the coupling, it is advantageous that the indentation line is formed in the press-in hole over a predetermined length section.

It may further include a separation prevention washer having a through-hole inserted into the anchor, disposed below the elastic holding member to prevent the elastic holding member from being separated from the anchor.

It may be further provided with a sinking prevention jaw provided on the elastic holding member to prevent the anchor from sinking downward in the anchor insertion hole.

An end portion of the anchor is provided with a step portion into which a press-fit hole, a through hole, and an anchor passage hole to be described later are fitted.

On the other hand, the anchor is further comprises a reinforcing plate is formed in the anchor passing hole on the plate surface, the anti-rotation protrusion is preferably formed in the reinforcing plate.

The anti-rotation protrusion may be formed by cutting and bending the plate surface of the reinforcing plate. It is preferable that a predetermined cut line is formed in the anchor through hole to facilitate coupling.

The reinforcing plate may be coupled to the bottom surface of the display unit by welding.

The anti-rotation protrusion may also be provided integrally with the display unit.

Hereinafter, a representative first embodiment of each embodiment will be described in detail, and only portions that are different from the first embodiment will be briefly described with respect to the remaining embodiments. In addition, even if description of the same structure which each embodiment has in the detailed description is abbreviate | omitted, the code | symbol between embodiment is distinguished.

As shown in FIGS. 1 to 3, the road sign bottle according to the first embodiment of the present invention extends from a lower portion of the display portion 10 and a display portion 10 exposed on the road surface R of the road to display a lane. And an anchor 20 embedded in the inner anchor insertion hole H of the road surface R.

The display portion 10 has a truncated cone shape. The upper surface of the display unit 10 is provided with a pattern carved portion 11 is a promotional design is engraved, the side portion is formed with a plurality of reflector mounting portion 12 along the circumferential direction. The reflector mounting portion 12 is coupled to the reflector 13, which is diffusely reflected by light.

In the present embodiment, the display unit 10 has a truncated cone shape to prevent the tire from being damaged even when the vehicle steps on the road sign. However, of course, the display unit 10 may have a rectangular block shape. The lower surface of the display unit 10 may be partially recessed (see FIGS. 2, 3, 9, and 10), and may have a flat plate shape as shown in FIGS. 11 and 12.

Between the display portion 10 and the anchor 20, a skirt portion 15 extending radially in parallel with the road surface R is formed. The skirt 15 is in close contact with the road surface R to gently compensate the slope between the road surface R and the display unit 10.

The anchor 20 has a shape with a through hole 41 of the press-in hole 31 of the elastic holding member 30, the separation preventing washer 40, and the anchor passing hole 51 of the reinforcing plate 50 to be described later. It is intended to have a cross-sectional non-circular shape for fitting. That is, it consists of the cross-section octahedron which has the recessed groove 21 recessed radially inward along the longitudinal direction. However, the anchor 20 may be composed of a polyhedron without the recessed groove 21 (see FIG. 10), or may be configured to have a cross-sectional cylindrical shape (see FIGS. 11 and 12).

The anchor 20 may be manufactured integrally with the display unit 10 (see FIG. 10), may be separately manufactured and welded to the display unit 10, or may be coupled by bolts 25 (see FIG. 3). . A step 23 is formed at the end of the anchor 20. In the present exemplary embodiment, the stepped part 23 is used as a part to which the press-in hole 31, the through-hole 41, and the anchor through-hole 51 are press-fitted and coupled. However, when a separate step portion 23 is not formed in the anchor 20, the size of the press-in hole 31, the through hole 41 and the anchor through hole 51 is increased to be coupled to the anchor 20. do. In addition, the shape of the stepped portions 23 to 23f may be changed.

The elastic retaining member 30 is coupled to the stepped portion 23 of the anchor 20, extends from the coupled portion is disposed adjacent to the side of the anchor 20, the anchor 20 is the anchor insertion hole (H) It has an elastic catching plate portion 33 elastically elastically radially outward with respect to the axis of the anchor 20 so as not to be separated from the.

As the engaging portion, it is employed as a press-in hole 31 which is drilled in the shape and size substantially the same as the cross-sectional shape of the stepped portion 23 of the anchor 20 and is fitted to the stepped portion 23. At this time, it is preferable that an incision line (not shown) is formed in the press-in hole 31 over a predetermined length section. Thus, when the stepped portion 23 of the anchor 20 is forcibly fitted into the indentation hole 31, the incision line is opened so that the anchor 20 can be easily indented into the indentation hole 31. However, after the anchor 20 is completely press-fitted into the press-in hole 31, the cut line is brought into close contact with the side of the anchor 20, so that the elastic retaining member 30 is stepped 23 of the anchor 20. It is not easy to get away from it. On the other hand, in addition to the above-described indentation hole 31, the coupling portion may be replaced with the bolts 32c and 32f (see FIGS. 9 and 12) and the like to couple the elastic retaining member 30 to the anchor 20, You can also apply the method.

A plurality of elastic latching plate portion 33 extending from the engaging portion is provided along the circumferential direction of the anchor 20. The elastic locking plate 33 is elastically urged radially outward with respect to the axis of the anchor 20. Therefore, when the anchor 20 is inserted into the anchor insertion hole (H), the front end of the elastic locking plate 33 is bent to the side of the anchor 20 and the anchor 20 is completely inserted into the anchor insertion hole (H) When elastically radially outwards the inner wall surface of the anchor insertion hole (H) is in contact with.

It is advantageous that the elastic catching plate portion 33 has a curvature surface corresponding to the side curvature of the anchor 20. The front end of the elastic locking plate 33 forms at least one locking step 34 which is held on the inner wall surface of the anchor insertion hole H along the direction in which the anchor 20 is separated from the anchor insertion hole H. .

In the stepped portion 23 of the anchor 20, a separation preventing washer 40 having a through hole 41 formed in the plate surface is interposed. The release preventing washer 40 is disposed under the elastic holding member 30 to prevent the elastic holding member 30 from being separated from the stepped portion 23 of the anchor 20. Also in the through-hole 41, it is more effective to provide an incision line (not shown) to facilitate the press-in operation.

On the other hand, the anchor 20 is coupled to the reinforcing plate 50 to prevent the display portion 10 installed on the road surface (R) to be arbitrarily rotated by the external force. An anchor passage hole 51 through which the anchor 20 passes is formed on the plate surface of the reinforcing plate 50. The anchor passage hole 51 is made to be substantially the same as the cross-sectional shape and size and shape of the anchor 20 to be fitted to the anchor 20.

When the anchor 20 is pressed into the anchor passing hole 51 to force the reinforcing plate 50 to the anchor 20, the reinforcing plate 50 is not rotated with respect to the anchor 20. In this case, a predetermined cut line (not shown) may be formed in the anchor passing hole 51 to allow the anchor 20 to be easily press-fit into the anchor passing hole 51.

The reinforcing plate 50 is provided with a plurality of anti-rotation protrusions 52 which protrude horizontally from the plate surface to the contact surface and are inserted into the road surface R to prevent the display portion 10 from rotating.

The anti-rotation protrusion 52 may be manufactured separately and coupled to the reinforcing plate 50, but is formed by cutting and bending the plate surface of the reinforcing plate 50 in the present embodiment. The anti-rotation protrusion 52 is sharply formed at its tip and is easily inserted into the road surface R, thereby preventing the display portion 10 from rotating. At this time, of course, the edge of the anti-rotation protrusion 52 may be rounded (see FIG. 10).

After the reinforcing plate 50 and the elastic retaining member 30 is assembled to the road sign bottle by such a configuration, the process of constructing the road surface R will be described with reference to FIGS. 4 to 6.

First, the anchor 20 is press-fitted into the anchor passing hole 51 formed in the reinforcing plate 50 so that the reinforcing plate 50 may be disposed on the lower surface of the display unit 10. Then, the anti-rotation protrusions 52 formed on the reinforcing plate 50 face downward. At this time, after the anchor 20 is inserted into the anchor passage hole 51, the reinforcing plate 50 may be rotated by a predetermined angle to prevent rotation of the reinforcing plate 50 (see FIG. 2).

When the coupling of the reinforcing plate 50 is completed, in order to couple the elastic holding member 30 to the stepped portion 23 of the anchor 20, the stepped portion 23 of the anchor 20, the elastic holding member 30 Press-fit into the press-in hole (31). Then, the stepped portion 23 of the anchor 20 can be easily pressed into the indentation hole 31 while the incision line formed in the indentation hole 31 is opened. When the press-fitting of the anchor 20 is completed, the opened cut line is elastically contacted with the side of the stepped portion 23 again, so that the elastic holding member 30 is not separated from the anchor 20. After such opening, the release preventing washer 40 is press-fitted into the stepped portion 23 of the anchor 20 so that the elastic holding member 30 does not escape to the lower end of the anchor 20.

When the coupling of the reinforcing plate 50 and the elastic retaining member 30 is completed, the position to install the road sign bottle is determined and the anchor insertion hole (H) is formed at the proper position of the road surface (R). In this case, in the conventional art, an operation of removing impurities such as dust or oil on the road surface R is necessarily performed in order to use an adhesive, but the present invention does not need to perform such an operation separately. Therefore, not only the construction is convenient but also the time required for construction can be reduced.

Then, after correspondingly arranging the anchor 20 in the anchor insertion hole (H), the road sign bottle is pressed toward the anchor insertion hole (H) side. Then, the front end engaging jaw 34 of the elastic locking plate 33 is bent toward the side of the anchor 20, the anchor 20 begins to be inserted into the anchor insertion hole (H), the insertion of the anchor 20 is completed When the elastic catching plate 33 is elastically urged outward in the radial direction. (Θ1 to θ3), the tip catching jaw 34 of the elastic catching plate 33 contacts the inner wall surface of the anchor insertion hole H. By doing so, the anchor 20 is prevented from being separated from the anchor insertion hole (H).

When the display unit 10 is pressed downward in the process of inserting the anchor 20 into the anchor insertion hole H, the rotation preventing protrusions 52 formed on the reinforcing plate 50 are inserted into the road surface R. Therefore, after completion of construction, the road sign bottle is not arbitrarily rotated by external force.

In the drawings of the present embodiment is shown so that the front end engaging jaw 34 of the elastic locking plate 33 to penetrate into the inner surface of the anchor insertion hole (H) and the inner wall surface of the elastic locking plate 33 and the anchor insertion hole (H) Although the spaces between are shown relatively broadly, they are only somewhat exaggerated to aid in the explanation and understanding of the drawings, and mention that little space actually occurs.

On the other hand, if the road sign bottle is to be removed from the road surface R, the road sign bottle is lifted upwards. Then, the elastic locking plate 33 is bent in the clockwise direction of the drawing out of the elastic limit and the locking jaw 34 is directed downward. At this time, when the display unit 10 of the road sign bottle is lifted upward, the demolition work of the road sign bottle is easily completed.

As such, the installation work of the road sign bottle according to the present invention can be completed very simply, the time required for construction can also be significantly reduced. In addition, since the road sign bottle according to the present invention does not use an adhesive such as an epoxy resin which is a carcinogen, it has an advantage of being environmentally friendly.

In addition, the construction can be easily carried out regardless of the construction constraints, including the value of the relative humidity in the air, the dry state of the road surface (R), etc., the road marking bottle completed by the anti-rotation protrusion 52 is the road surface ( Rotation on R) can be prevented.

In addition to the above-described embodiment, as shown in FIG. 7, the elastic holding member 30a in which the locking step 34a is formed may be doubled.

In addition, as shown in FIG. 8, if the additional locking step 60b is provided by drilling the plate surface of the elastic locking plate part 33b, the effect of the present invention becomes more excellent. At this time, at least one of the locking jaws may be prevented from sinking downward in the anchor insertion hole H by using the sinking prevention jaw 61b having the opposite direction.

In the above-described embodiment, a separate reinforcing plate 50 to 50d is provided and the anti-rotation protrusions 52 to 52d are formed on the reinforcing plates 50 to 50d. However, as shown in FIG. 11, the anti-rotation protrusion 52e may be integrally provided on the lower surface of the display portion 10e.

However, as shown in FIG. 12, when the materials of the anti-rotation protrusion 52f and the display portion 10f are different from each other and are not welded to each other, an additional flange portion 65f is attached to the anti-rotation protrusion 52f. The flange portion 65f and the display portion 10f may be mutually screwed together or riveted together (not shown).

Although the above-described embodiment has been described with respect to the display unit on which the identification pattern is formed, it goes without saying that the idea of the present invention can be applied to a road sign bottle provided with a separate light emitting means in the display unit.

As described above, according to the present invention, there is provided a road sign bottle that can not only be easily constructed but also reduce the time required for construction.

In addition, since the use of adhesives such as epoxy resin, a carcinogen during construction, an environmentally friendly road sign bottle is provided, and the road sign bottle according to the present invention is easy to recycle.

In addition, the road sign bottle of the present invention can be easily installed regardless of the construction constraints, including whether the value of the relative humidity in the air, dryness of the road surface, etc., and the road sign bottle is arbitrarily rotated by external force in the completed construction state. Can be prevented.
