The present invention relates to pillars used as pillars, for example, street lights, traffic lights for vehicles and pedestrian crossings, road guides, road billboards, etc. More specifically, various patterns such as wooden patterns without liquid coating on the surface of the pillars The thermal transfer film that transfers the prints is deposited in a vacuum to prevent lifting and escape even under adverse conditions such as ultraviolet rays and salts, and is transferred by applying heat to the prop itself, so that various patterns suitable for the surrounding environment of the road and nature are special. The present invention relates to a supporter and a method of manufacturing the same, which can freely produce a texture effect, and which is prolonged in life by prolonging its life due to excellent rust prevention, discoloration resistance, durability and wear resistance.

In general, struts used as streetlights installed around roads or as pillars for traffic lights, road guides, road billboards for pedestrians and pedestrian crossings are formed at the installation location, and then form foundation molds and cast and cure concrete. A foundation is formed and then covered and a strut is installed in the anchor formed on the foundation.

Since the pillars installed in this way have to maintain their robustness even in harsh environments for a long time, they use metal tubes, and mainly cast iron or stainless steel.

However, the cast iron struts can be easily molded to produce various designs and have a low price. However, liquid coating works using organic solvents, reactive monomers, and water solvents used in general paints on the surface of the struts are performed. By producing, not only problems such as pollution problems such as air pollution and water pollution and problems such as efficiency thick film formation (defect of the coating film) are generated, but also harmful solvents may harm the health of the workers.

In addition, since the coated coating is easily peeled off or discolored by a harsh environment such as ultraviolet rays after the installation of the prop, it may not look very good even in aesthetic appearance, and the part where the coating is peeled off due to rain or snow may be corroded more quickly. The worker has to use the articulated crane or ladder installed with a basket at regular intervals, and thus, the painting work is again performed. Therefore, the waste of the cost and the risk of the painting work are also pointed out as a high problem.

In addition, the stainless steel pillar has the advantages of corrosion resistance and smooth surface, but expensive and cast iron has the disadvantage of giving a unique cold feeling, as well as these pillars are installed depending on the purpose of use irrespective of the surrounding environment This is most often the case.

Recently, in the fields of application of the present invention, metals such as aluminum, steel, stainless steel, etc., in order to produce products with high durability, weather resistance, corrosion resistance, fire resistance, water resistance, easy management and repair, economical efficiency, and excellent processability Metal panels manufactured by thermally transferring the shape of wood, marble, granite, fancy patterns, etc. on the surface of the product are being produced and commercialized.

As an example of such a metal panel, it is known by the Republic of Korea Patent Publication No. 2003-33795 (name: sheet transfer apparatus for producing a surface of the heat transfer metal panel and its manufacturing method).

According to the sheet transfer apparatus for manufacturing a metal panel whose surface is thermally transferred according to the above-described Patent Publication No. 2003-33795, various windows, interior materials, various show-cases / counter tops, etc. Manufacture metal panels used for partitions and fire / fashion doors, various furniture, kitchen and bathroom items, various electronics cases, fan coil units, building exteriors / ceilings, roofing materials, and canopies In the apparatus, the surface-treated and powder-coated metal panel is processed to a certain size, and the monorail path is routed to the first and second working tables one by one by using a suction plate that interlocks with a lifting cylinder in a place where it is stacked. A seat money plate for supplying and moving along with the worktable, the worktable composed of the first and second worktables on which the metal panel is placed, and the left and right movements moved by the position shifting cylinder and placed on the worktable. A stamping machine for thermally transferring a designated shape to the inner panel, a protection film application machine for coating a protective film to protect the surface of the thermally transferred metal panel, a motorized roller conveyor for transporting the finished product to a lifting table, and the transfer The lifting table is configured to lift and load the finished product, wherein the first and second work benches are respectively provided with a double heating upper plate for raising heat by raising and lowering the metal panel mounted on the work bench by lifting up and down the cylinder. The stamping machine is a stamping film coil for supplying a stamping film printed in the shape of wood, marble, fancy pattern, and the like, and an upper silicon nomax felt to support the rising of the double heating upper plate so that the metal panel is thermally transferred. And, the configuration of the waste film rewinder winding the spent heat transfer stamping film Characterized by, it can be seen that to manufacture the thermal transfer film is transferred on a metal panel surface.

However, in order to manufacture a metal panel thermally transferred to the surface using the above-described sheet transfer value, the surface of one surface of the metal panel is coated with powder, and then the surface of the powder is coated with wood, marble, granite, A thermal transfer film printed with various shapes such as a pansy pattern is transferred by pressing and heating, wherein the thermal transfer film is simply pressed and heated by a stamping machine while being transferred to a powder surface of a metal panel, thereby transferring the thermal transfer film. Bubbles may be generated between the surface of the powder and the thermal transfer film. Moreover, when the surface of the metal panel is not smooth or the coated powder becomes convex, the thermal transfer film is not uniformly transferred to the metal surface. Not only the transfer strength is very weak, but also a lot of bubbles are generated, which in turn causes product defects. I had a problem.

In addition, when the metal panel manufactured as described above is used under adverse conditions such as ultraviolet rays and salts, the thermal transfer film is gradually lifted from the surface of the metal panel over time, and is severely peeled off from the surface of the metal panel. It was inherent to the problem of harm.

In addition, the transfer of the thermal transfer film to the surface of the metal panel by the above manufacturing method is possible only when the metal panel is a rectangular plate body, another operation to transfer the thermal transfer film to the metal tube such as cylindrical or octagonal There is a problem that can be expected.

Therefore, the present invention was devised under the above-mentioned background, and an object of the present invention is to transfer a wooden pattern or various pattern prints on the entire surface of a pillar used as a pillar such as a street light, a traffic light, a road guide board, a road billboard. The thermal transfer film is vacuum-deposited to prevent bubbles from being lifted and released even under adverse conditions such as ultraviolet rays and salts, so that various patterns, natural textures and natural patterns suited to the surrounding environment can be produced. It is to provide a support by environmentally friendly thermal transfer film adhesion, which is coated with a certain thickness on the outer surface of the metal tube which is cut and surface treated according to the standard and wood or various forms on the coated powder coating layer After depositing the thermal transfer film having a pattern of vacuum to avoid bubble generation, the deposited thermal transfer This is achieved by giving names to melt by heating the metal tube to be transferred impermeable to the powder coating layer.

Another object of the present invention is to provide a method of manufacturing a support by bonding a thermal transfer film, which is more convenient when the transfer of the thermal transfer film having a tree pattern or various patterns on the surface of the support and does not cause a defect of the product, This strut manufacturing method is achieved by wrapping a metal tube with a powder coating layer on its surface with a thermal transfer film coated with a wooden pattern or various patterns, and then depositing it under vacuum to prevent bubbles, and heating the metal tube.

Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above objects, the posts of the thermal transfer film adhesive according to the present invention are molded in a metal tube and installed on the ground, such as street lights, traffic lights for vehicles and pedestrian crossing pedestrians, road guide boards, road billboards, etc. ,

The post is cut according to the standard, and a thermal transfer film having a wood pattern or various patterns on the entire surface of the metal tube body having a powder coating layer having a constant thickness on the surface is deposited in a vacuum without foaming, The deposited thermal transfer film is melted and transferred to the powder coating layer.

According to the method of manufacturing a support by the thermal transfer film bonding according to the present invention, in the method for manufacturing a support used as a pillar, such as traffic lights, road guides, road billboards for streetlights, vehicles and pedestrian crossings, it is cut according to specifications. The metal tube formed with a powder coating layer having a predetermined thickness on the surface is wrapped in a polyethylene film or a polyester film with a thermal transfer film coated with a wooden pattern or various patterns, and then deposited under vacuum to avoid bubble formation. The metal tube is heated to 180 ° C to 200 ° C so that the film is melted and transferred to the powder coating layer.

Thus, after forming the powder coating layer on the surface of the pillar used as a pillar, such as street lamps, traffic lights, road guides, road billboards, etc., a thermal transfer film coated with a wooden pattern or various types of patterns is vacuumed on the powder coating layer. It can be seen that the desired posts are obtained by depositing and transferring to heat.

As a result, a thermal transfer film coated with a wood pattern or various patterns is vacuum deposited on the surface of the support surface and melted and transferred by heat, whereby air bubbles may be generated between the powder coating layer and the thermal transfer film. In addition, even under adverse conditions such as ultraviolet rays and salts, the thermal transfer film is not lifted or detached, and the liquid coating is not used during the production of the pillar, so that pollution problems such as air pollution and water pollution are not generated. There is an advantage to getting environmentally friendly landlords.

And, there may be a plurality of embodiments of the present invention, the following most preferred embodiments will be described in detail.

Through this preferred embodiment, the objects, other objects, features and advantages of the present invention will become more apparent from the following description with an embodiment according to the present invention in connection with the accompanying drawings shown for illustrative purposes.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the post and the manufacturing method by the thermal transfer film adhesion according to the present invention.

1 is a perspective view of an embodiment showing a street lamp post by thermal transfer film bonding according to the present invention, Figure 2 is a partially enlarged cross-sectional view of the street lamp post of Figure 1 shown by cutting in the longitudinal direction.

As shown in FIGS. 1 and 2, the support by the thermal transfer film adhesion according to the present embodiment is first cut to the standard of the support 10, such as cast iron, and then the cut metal pipe. Pretreatment is carried out to remove impurities and the like from (20).

When the pretreatment process is completed, a mixture of synthetic resins of polyethylene (PE) or polyester (PET) and pigment and curing agent filler is cooled to uniformly melt and inject the injector into a predetermined range. The powdery powder coating having only a particle size in a prescribed range by pulverizing to a same color as the thermal transfer film 40 to be described later in detail, that is, the surface of the pretreated metal tube 20, that is, the metal tube 20 The powder coating layer 30 is formed by coating the entire outer surface and a portion of the inner surface of the upper and lower portions of the metal tube 20 shown in FIG. 3. This eliminates the necessity of maintenance work in case of fine peeling or partial adhesion failure of the thermal transfer film 40 and maintains the color of the thermal transfer film 40 as it is, and also improves the adhesive force of the thermal transfer film 40. For sake.

Subsequently, the entire surface of the powder coating layer 30 coated on the outer surface of the metal tube 20 with the thermal transfer film 40 coated with various patterns such as wood patterns on the polyethylene film or the polyester film, and also the metal tube At the upper end and the lower end of the 20, the thermal transfer film 40 is finished as the finishing work of the thermal transfer film 40, as shown in FIG. Then, the thermal transfer film 40 is deposited to prevent bubbles from occurring on the surface of the powder coating layer 30 under vacuum using a vacuum apparatus such as a vacuum pump.

Subsequently, the thermal transfer film 40 deposited under the vacuum is heated to about 180 ° C. to 200 ° C. so that the metal tube 20 is transferred to the powder coating layer 30 so that transfer is performed. Melted by the heat of the metal tube body 20, the powder coating layer 30 formed on the entire outer surface of the metal tube body 20 and a part of the inner surface of the upper and lower parts of the metal tube body 20 is evenly penetrated without bubble generation. By being made is to produce the desired post 10 as shown in FIG. Here, the metal tube 20 is wrapped with the thermal transfer film 40 without using a vacuum deposition method, and then a thermal pressure roller (not shown in the drawing) of a synthetic rubber material having a temperature condition of about 180 ° C to 200 ° C. It is conceivable to pressurize the above-described thermal transfer film 40 to transfer it to the powder coating layer 30. In this case, however, the thermal transfer film 40 is subjected to a surface treatment state of the metal tube 20, for example, surface treatment. When the rough or powder coating layer 30 is coated, for example, when the powder coating layer 30 is not smoothly painted or embossed, the thermal transfer film 40 is coated with the powder coating layer 30. Fine bubbles are generated between the powder coating layer 30 and the thermal transfer film 40 without being uniformly transferred to the substrate. When the struts thus prepared are used under environmental adverse conditions such as ultraviolet rays or salts, they are lifted from the bubble generating portion. If something happens Badly will that might be leaving the thermal transfer film. Therefore, in order to solve this problem, it is preferable to use a vacuum deposition method.

As another example of the present invention, the thermal transfer film 40 is directly transferred to the metal tube 20 without applying the above-described powder coating. That is, as mentioned above, after cutting the metal tube 20, such as cast iron in accordance with the standard of the support 10, and undergoes a pre-treatment process for removing impurities and the like from the cut metal tube 20. When the pretreatment process is completed, the entire surface of the outer surface of the metal tube 20 is wrapped with the above-described thermal transfer film 40, and at the upper end and the lower end of the metal tube 20, the thermal transfer film 40 is finished as the finishing work. The film 40 is folded into the inside of the metal tube 20 to cover the inner surface of the metal tube 20, and then the thermal transfer film 40 is deposited on the surface of the metal tube 20 using the vacuum apparatus described above. After that, the metal tube 20 is heated to about 180 ° C to 200 ° C for transfer. By not applying the powder coating in this way, the work is easier, and thereby the productivity of the support 10 can be improved, and the thermal transfer film 40 can be prevented from rust and the discoloration resistance and the wear resistance can be improved. .

On the other hand, as a comparative example, by producing a liquid coating work on the surface of the pillar that is used as a conventional technology, that is, street lamps, traffic lights or road signs, road billboards, etc., pollution problems such as air pollution and water pollution occur. In addition, the coating is easily peeled off by the surrounding environment to damage the aesthetics of the surroundings. The present invention provides a powder coating on the outer surface of the metal tube that is cut and surface treated according to the standard, and the wooden pattern or the like on the painted powder coating layer. It can be seen that the environmentally friendly thermal transfer film coated with various patterns is deposited in a vacuum without bubble generation and then transferred by heating to a metal tube to produce it.

As a result, according to the present invention, since the powder coating layer is formed on the surface of the support, and the thermal transfer film coated with wood or various patterns is completely transferred without bubbles and lifting by vacuum deposition and heat, ultraviolet rays, The thermal transfer film does not deviate from the surface of the column even under adverse environmental conditions such as salt, and such a pillar not only fits well with the surrounding environment of the road but also does not use liquid paint, so that air pollution and water pollution, etc. It has the advantage of producing environmentally friendly landowners that do not cause pollution problems.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

According to the strut by the thermal transfer film adhesion of the present invention, which is apparent from the above description, and a manufacturing method thereof, a powder coating layer excellent in rust prevention, discoloration resistance, and abrasion resistance is formed on the surface of the strut, and there are various Since the thermal transfer film having a pattern in the form is deposited in a vacuum without bubbles and is melted and transferred by heat, the thermal transfer film does not lift or drop from the surface of the support even under adverse conditions such as ultraviolet rays and salts, In addition, it has a harmonious effect on any surrounding environment, such as expressing a warm feeling like wood and a natural aesthetic.

In addition, by not coating the liquid paint on the surface of the support, there is no fear of harm to the health of the operator and pollution problems such as air pollution or water pollution, and there is no fear of peeling and corrosion of the coating has the effect of extending the life.
