BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a road sign device installed on a road for informing location information about a road, a building or a street name for convenience of a driver or a pedestrian, The present invention relates to a road marking device which is constructed in a cylindrical shape and is firmly supported on a support post so that an extremely stable installation state can be maintained even against external forces such as strong winds.

Generally, at the edge of a road, a traffic sign for securing safe and smooth road traffic by informing drivers and pedestrians of various dangerous matters that may occur on the road, various information related to the road such as a road And various road signs such as a guide sign for informing position information on the direction, distance, or place of the road.

These road signs are usually installed at the appropriate height on the roadway so that the driver or the pedestrian can easily recognize the matters to be conveyed, and the signs marked with the markings are supported on the roads in the form of cantilevers.

In the most common form, a hanger is installed horizontally by a band clamp on the upper end of the strut, and the sign is attached to the hanger or the sign is attached directly to the band clamp. In this case, an external force is applied to the sign If the signs are easily turned around, it is likely to point to the wrong place. In addition, if a plurality of signboards are installed on a single support, the plurality of hangers must be installed so as to be spaced apart.

Particularly, since the sign has only a thin plate shape or has a reinforcing frame of an appropriate diameter only at the upper end and the lower end of the plate-like body, it has a weak physical strength and is easily deformed or broken by an external force.

In order to solve such a problem, for example, Korean Patent Registration No. 0245545 and Utility Model Registration No. 0225257 disclose a structure in which a plurality of assembly grooves are radially formed on the outer periphery of a support, The signboard holder is assembled and fixed, and the signboard is fastened to the channel of the signboard holder and fastened with bolts to provide a road sign that allows multiple signboards to be installed easily and beautifully on one support It is also.

However, these prior arts also suffer from structural weakness because the channel of the sign holder only grasps a thin body portion except for the reinforcing frame of the sign in the state that the sign is made of a thin plate having a reinforcing frame at the upper and lower ends of the body , So that when an external force due to physical contact is applied, the sign may easily bend easily.

Disclosure of the Invention The present invention has been developed in order to solve the above-mentioned problems of the prior art. The present invention has been made in view of the above problems, and it is an object of the present invention to provide a high- And it is an object of the present invention to provide a road marking apparatus which can be easily deformed or can maintain a very stable installation state without changing the installation position.

Another object of the present invention is to provide a road marking apparatus which can easily and simply install a plurality of sign boards on one support as required.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a road marking apparatus comprising: a support having a plurality of dovetail assembling grooves radially formed on a foundation concrete embedded in the ground; A sign fixture having a dovetail type assembling protrusion at one side of the body and being coupled to an assembly groove of the strut and then to be mounted so as to protrude from the outer periphery of the strut; A tubular sign composed of a hollow plate of a certain thickness with both open ends and one opening inserted into the sign fixing means, And a closing side plate closing the other opening of the sign.

According to a preferred aspect of the present invention, the drainage grooves are formed by protruding the flanges on the front and rear sides of the top surface of the tubular signboard, respectively, thereby suppressing the contamination of the signboard due to rain.

According to another preferred feature of the present invention, the support and the sign, the sign fixing plate and the finishing side plate are formed by extruding aluminum which is lightweight and excellent in corrosion resistance.

Accordingly, it is an object of the present invention to provide a sign board having a high physical strength and a very strong support for a support as compared with a conventional board having a thin plate shape so that it can be easily deformed from external physical contact, .

In addition, even when it is necessary to install a plurality of signs on a single pillar, it is possible to install the pillar easily and simply, thereby improving the field and stability of the road marking device and improving the road aesthetic effect.

Hereinafter, preferred embodiments of the road marking apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, the road marking apparatus according to the present invention comprises a support 10 vertically installed on the road side, a sign fixture 20 mounted on the upper end of the support post 10, And a closing side plate 40 for closing the opening of the front side of the sign board 30.

The pillars 10 are made of, for example, pipes of a circular section, and have a plurality of substantially dovetail type assembling grooves 11 formed at equal angular intervals radially on the outer periphery thereof. Although four assembly grooves 11 are illustrated in the illustrated embodiment, the assembly grooves 11 may be provided more than four.

The column 10 is manufactured by extruding a lightweight and corrosion-resistant nonferrous metal, preferably aluminum.

The column 10 has a base 12 at a lower end thereof and is vertically installed on a road by being fastened with an anchor bolt of a foundation concrete (not shown)

The sign fixing member 20 is assembled to the support 10 by vertically extending a dovetail type assembling protrusion 22 slidably coupled to the assembly groove 11 of the support 10 on one side of the body 21 , And screw holes (23) at the top and the bottom, and are integrally fastened to the struts (10) by bolts (24).

The body 21 is formed in a channel shape having a U-shaped cross section and has bosses 25 for fastening the mark 30 on the inner surface of the front end of the both side walls 21a. At this time, the width of the body 21 (the distance between the two side walls) is larger than the opening 11a of the mounting groove 11 of the support 10, It is preferable that the flange 11b of the flange 11 is fitted.

A cover flange 26 in the form of an angle having an approximately b-shaped cross section is further provided on both sides of the fixed end of the sign fastening body 20 so as to insert both side end edges of the fixed end of the sign board 30 Thereby stably supporting the sign 30 more beautifully.

Such a sign fixture 20 is also manufactured by extruding aluminum which is light in weight and excellent in corrosion resistance.

Since aluminum is a soft non-ferrous metal, when the bolt 24 is fastened to the support 10 through the screw hole 23 of the sign fastener 20, the external force such as wind, The screw hole 23 of the sign fixture 20 which is relatively weaker than the bolt 24 is easily worn by the bolt 24 so that the fastening force of the sign fixture 20 with respect to the support post 10 is weakened, The bolt 24 may be detached.

Accordingly, a helical coil 27 made of a hard metal is coupled to the screw hole 23 of the sign fastener 20 such that the inner and outer peripheries of the sign fastener 20 are both threaded.

The helical coil 27 is wound around a metal wire having a rhomboidal cross section in the form of a coil. When the bolt 24 is engaged, each of the windings is slightly widened in the axial direction, The fastening force is increased to reliably prevent the general bolt 24 from being loosened.

The helical coil 27 is preferably made of stainless steel having excellent mechanical strength and corrosion resistance.

The sign 30 is made of a hollow plate having an appropriate thickness and has a rectangular cross-section. This sign 30 is also made by aluminum extrusion processing, so that both ends of the sign 30 are open.

The upper surface of the sign 30 may be formed on both the upper surface and the lower surface of the sign 30 so as to prevent the rain from flowing down to the front surface and the rear surface of the sign 30, 31 are formed in the circumferential direction thereof.

The drain grooves 31 are formed by projecting upwardly a flange 32 of an appropriate height to the front and rear edges of the upper surface of the sign 30, respectively.

A plurality of fastening holes 33 for fastening the sign 30 to the boss 25 of the sign fastener 20 with bolts 34 are formed on the top and bottom surfaces of the sign 30.

On the other hand, a reflection sheet and a film on which a predetermined cover is written are attached to the front surface (front and rear surfaces) of the sign 30.

The finishing side panel 40 may be assembled in the free end opening of the signboard 30 in various ways, but it is preferable that the fixing traces of both are not exposed to the outside for the purpose of the appearance of the signboard.

To this end, the finishing side panel 40 is provided with a pair of fitting pieces 41 protruding in a state of being spaced apart from each other by being fitted to the opening of the marking plate 30 on one side and being in close contact with the inner and outer surfaces of the front and rear sides, And is adhered by a curable synthetic resin adhesive 43. At this time, an arc-shaped bending portion 42 is formed at the tip end of each of the fitting pieces 41 so as to prevent the finished side plate 40 from being separated easily from the mark 30 So that the adhesive 43 is hardened in a state filled in the groove 43a of the bending portion 42. [

That is, the bendable portion 42 is bent at the front end of the fitting piece 41 of the finishing side plate 40 (away from the inner surface of the marking plate) so that the bending portion 42 of the marking plate 30 5B, a part of the adhesive 43 is pushed by the fitting piece 41 so as to be pushed into the groove 42a of the bending portion 42. As a result, The bending portion 42 of the fitting piece 41 enters the groove 42a and is caught by the adhesive 43 hardened in a protruding state so that the rigid The attachment state can be maintained.

Reference numeral 50 denotes a strut tower, and 60 denotes a protective cover for protecting the lower end of the strut 10 by covering it.

Next, an installation process of the road marking apparatus according to the present invention will be described.

First, the finishing side plate 40 is fixed to one opening of the mark 30 with an adhesive 43. In this state, the assembling protrusion 22 of the sign fastener 20 is inserted into the assembling groove 11 provided on the outer periphery of the support 10, and then the support 10 is inserted through the screw hole 23 formed in the upper and lower portions thereof Tighten with bolts (24).

The sign 30 is assembled so that the other opening of the sign 30 formed in a tubular shape is inserted into the body 21 of the sign fastener 20 mounted on the outer periphery of the post 10, The bolts 24 are fastened to the fastening bosses 25 of the sign fastener 20 through the fastening holes 13 formed on the upper and lower surfaces of the fastener 20 to complete the installation.

At this time, when it is necessary to simultaneously install several (at least two or more) signs 30 on one strut 10, as shown in Fig. 6, The sign board 30 can be easily installed to each of the assembly grooves 11 by the above-described method.

As described above, according to the present invention, not only the sign 30 can be installed on the support 10 by a relatively simple operation, but also a plurality of sign boards 30 can be installed simultaneously in a plurality of directions with respect to one support 10 .

Particularly, since the sign 30 is inserted into the column 10 having a certain thickness and is fixed to the column 10, not only the supporting force of the sign 30 with respect to the column 10 but also the strength of the sign 30 And the bending deformation due to an external force such as contact with the outside or strong wind can be effectively prevented.

In addition, the sign 30 is fastened on the top and bottom surfaces of the sign fastener 20 while the sign fastener 20 is inserted, and the finished side plate 40 is also inserted into the sign 30 through the fastener 41, It is possible to realize a beautiful appearance since the signs 30 are formed in a cylinder and the fixing marks 20 are not exposed to the fixing plate 20 or the finishing side plate 40 to be assembled to the front end thereof.

Especially, the drainage grooves 31 are formed on the upper surface of the signboard 30 so that the signboard 30 is not easily contaminated because the rain or snow does not flow to the front and back surfaces of the signboard 30.

In addition, since each component is made of aluminum, oxidation corrosion caused by snow or rain does not occur, and the appearance can be maintained constantly, which is very advantageous in terms of maintenance.

As described above, according to the road marking apparatus of the present invention, the signboard can be installed very easily with respect to the support, and the support strength of the signboard itself and the signboard to the support is extremely excellent. Can be suppressed as much as possible.

Further, if necessary, a plurality of sign boards can be installed simultaneously in a plurality of directions with respect to one support, and each component is made of aluminum, so that no oxidation corrosion occurs.

Therefore, the present invention has an excellent effect of contributing greatly to the improvement of the field and stability of the road marking apparatus, the extension of the life span and the ease of maintenance.
