Description

Road sign {ROAD SIGN BOARD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign, more particularly, to a V-shaped or U-shaped folded road sign.

Generally, on roads where vehicles are traveling, various road signs are installed to protect vehicles or pedestrians, such as guide rails, median separators, barrier walls, and support posts. Among these road signs, there is a bent V-shaped road sign at the center.

Such a bent V-shaped road signboard is typically formed of an aluminum panel. A process for producing a road sign made of an aluminum panel typically comprises cutting an aluminum panel to a prescribed size, forming a V-shaped groove pattern at the center of the aluminum panel, and forming a V- And folding the aluminum panel.

At this time, the aluminum panel having a thickness of 2 mm to 3 mm, which is usually made of aluminum, is hard and difficult to process, and the step of forming the V-shaped groove pattern is manually performed, for example, by using a press machine. However, in the case of manufacturing by hand, it is difficult to form an aluminum panel having a uniform quality, in particular, the V-shaped groove pattern is difficult to have a uniform depth, and the aluminum panel may be partially cut.

Further, when the aluminum panel is folded, it is difficult to adjust the angle of the aluminum panel. Further, it is necessary to carry the aluminum panel in a bent state, and the weight of the aluminum panel is heavy, which makes it difficult to carry and install.

In addition, when a vehicle collides with a road sign made of an aluminum panel, the aluminum panel is hard and heavy, so that the vehicle is greatly damaged and a secondary accident due to the aluminum panel may occur.

An object of the present invention is to provide a road sign which is easy to form a groove pattern for bending and which can be easily bent when an aluminum composite body including a core layer disposed between two aluminum skin layers is used .

Another object of the present invention is to provide a road sign which can be easily transported and installed, weight is reduced, and secondary damage can be reduced even if an accident occurs in a vehicle.

According to an aspect of the present invention, there is provided a road sign comprising: a first aluminum skin layer and a second aluminum skin layer; And a core layer disposed between the first aluminum skin layer and the second aluminum skin layer and including a resin, wherein a groove pattern is formed at a central portion of the surface on which the first aluminum skin layer is disposed.

And a reflective sheet disposed on one side of the second aluminum skin layer on which the core layer is not disposed.

The resin may comprise polyethylene.

The thickness of the first aluminum skin layer and the second aluminum skin layer may be 0.1 mm to 0.5 mm, respectively.

The groove pattern may be formed by removing at least a part of the first aluminum skin layer and the core layer in the pattern forming region.

The depth of the groove pattern may be less than or equal to the sum of the thickness of the first aluminum skin layer and the thickness of the core layer.

The sum of the thicknesses of the first aluminum skin layer, the core layer, and the second aluminum skin layer may be 2 mm to 5 mm, and the depth of the groove pattern may be 1 mm or more.

At least one of the first aluminum skin layer and the second aluminum skin layer may be subjected to surface treatment of at least one of an allodyne treatment, a fluororesin coating, and a polyester resin coating.

The road sign may be a V-shaped or U-shaped folded road sign.

FIG. 1 is a sectional view of a road sign according to the present invention, FIG. 2 is a bottom view of the road sign according to the present invention, and FIG. 3 is a plan view of the road sign according to the present invention. Figs. 4 and 5 are diagrams showing a V-shaped road sign of the present invention. Fig.

1 to 3, the road sign 100 includes a first aluminum skin layer 110, a second aluminum skin layer 130, and a first aluminum skin layer 110 and a second aluminum skin layer And a core layer 120 disposed between the core layers 120 and 130. A groove pattern 150 is formed at the center of the surface on which the first aluminum skin layer 110 is disposed.

Referring to FIGS. 4 and 5, the road sign 100 according to the present invention may be a folded road sign, for example, a V-shaped road sign. However, the present invention is not limited to this, and it may be a U-shaped road sign if necessary.

The reflective sheet 140 may be disposed on the second aluminum skin layer 130 on one surface on which the core layer 120 is not disposed. That is, the reflective sheet 140, the second aluminum skin layer 130, the core layer 120, and the first aluminum skin layer 110 are sequentially laminated. In the surface where the first aluminum skin layer 110 is formed, A pattern 150 is formed.

The thicknesses of the first aluminum skin layer 110 and the second aluminum skin layer 130 are each about 0.1 mm to about 0.5 mm, preferably about 0.1 mm to about 0.3 mm, more preferably about 0.1 mm to about 0.3 mm, About 0.2 mm. When the thickness of the aluminum skin layer is less than about 0.1 mm, the strength of the road sign may decrease, and if the thickness of the aluminum skin layer is more than about 0.5 mm, the workability may decrease.

In the past, aluminum panels of about 2 mm to about 3 mm made of aluminum have been used, which makes it difficult to process. However, the present invention uses two aluminum skin layers having a small thickness to improve the workability while maintaining the strength of the road sign can do. That is, the aluminum skin layer having such a thickness does not require any manual operation at the time of forming the groove pattern 150, and can be processed using a mechanism (for example, a router device).

At least one of the first aluminum skin layer 110 and the second aluminum skin layer 130 may be subjected to at least one surface treatment of allodyne treatment, fluororesin coating, and polyester resin coating. This surface treatment can prevent oxidation on the surface of aluminum.

The core layer 120 comprises a resin. The resin may comprise polyethylene. The core layer 120 comprising the resin can be cut or patterned using a tool.

Further, these resins are smaller in weight than aluminum in the same volume. Therefore, the weight of the road sign 100 including the core layer 120 can be reduced, and the road sign 100 can be easily carried and installed.

Further, the core layer 120 including the resin can absorb the impact when an accident that a vehicle collides occurs. Therefore, it is possible to provide the road sign 100 capable of reducing the secondary damage even if an accident occurs in which the vehicle collides.

The groove pattern 150 may serve as a guideline for forming a V-shaped or U-shaped bent road sign. The groove pattern 150 is formed on the surface of the road sign 100 on which the first aluminum skin layer 110 is disposed and extends in one direction at the center of the road sign 100. The groove pattern 150 may have a U-shape.

The groove pattern 150 may be formed using a mechanism such as a router device. This has a uniform depth and can shorten the processing time of the groove pattern 150.

The groove pattern 150 is formed by removing at least a part of the first aluminum skin layer 110 and the core layer 120 in the pattern forming region. The depth of the groove pattern 150 may be less than or equal to the sum of the thickness of the first aluminum skin layer 110 and the thickness of the core layer 120. That is, a part of the core layer 120 is removed in the pattern formation region, the core layer 120 is exposed, and the entirety of the core layer 120 is removed in the pattern formation region to expose the second aluminum skin layer 130 . For example, the sum of the thicknesses of the first aluminum skin layer 110, the core layer 120 and the second aluminum skin layer 130 is 2 mm to 5 mm, and the depth of the groove pattern may be 1 mm or more.

The second aluminum skin layer 130 and the core layer 120 having a thin thickness are flexible compared with aluminum panels having a conventional thick thickness and are excellent in this power. Thus, when the road sign 100 is bent along the groove pattern 150 after the groove pattern 150 is formed, the angle of the road sign 100 is freely adjustable. That is, the bent two sides of the V-shaped bent road sign 100 may have a 0 ° to 180 °

There is a problem in that it is difficult to bend the aluminum panel conventionally and it is difficult to adjust the angle additionally, and the aluminum panel in the bent state must be carried and installed. However, the road sign 100 according to the present invention is transported in a planar shape and can be freely installed at a required angle while being installed.

The reflective sheet 140 displays the cover contents of the road sign. Referring to FIGS. 3 and 5, the reflective sheet 140 displays the cover contents of the seagull signs on the drawing, but is not limited thereto. That is, it is sufficient for the reflective sheet 140 to display the cover content generally used for the road sign.

A method of making the road sign 100 according to the present invention comprises the steps of making an aluminum composite comprising a first aluminum skin layer 110, a core layer 120 and a second aluminum skin layer 130, A step of adhering the reflective sheet 140 to one side of the second aluminum skin layer 130 and a step of forming the groove pattern 150 on the first aluminum skin layer 110 using, for example, a router device But is not limited thereto. At this time, the aluminum composite body including the first aluminum skin layer 110, the core layer 120, and the second aluminum skin layer 130 may be manufactured by extrusion, for example, by a thermal compression method.

Although not shown in the drawing, a reinforcing bar for installing guide rails and support posts on the first aluminum skin layer 110 on which the groove pattern 150 is formed may be installed. Such a reinforcing bar may be installed on the first aluminum skin layer 110 using a rivet.

Aluminum panels made of conventional aluminum and having a thickness of 2 mm or more are difficult to install the reinforcing bars by rivets and require a welding process. However, the welding process may cause problems such as the use of the welding gas and the expansion of the aluminum panel. The road sign 100 according to the present invention can be installed using a rivet, thereby preventing the problems in the welding process.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims. Accordingly, the scope of protection of the present invention should be construed to cover not only the following claims, but also their equivalents.
