The present invention relates to a method capable of realizing fine patterns on the surface of a sidewalk block formed of concrete, particularly a sidewalk block with excellent rigidity, and a sidewalk block manufactured by such a method, and more particularly, to a sidewalk block with various patterns and patterns on the surface of the sidewalk block. It is designed to provide a new aesthetic sense to pedestrians by directing the color finely and precisely, and to obtain advertising and publicity effects such as the characteristics of the place where the sidewalk block is installed.

In general, a sidewalk block is a building material used when constructing a floor or a sidewalk of a building, and a concrete block made of a polyhedral shape is mainly used.

In addition, such a sidewalk block is to be molded of concrete having excellent strength rather than general concrete in order to prevent easy damage by repeated impact or salt.

In addition, in recent years, such sidewalk blocks are advertised not only for direction indication but also for various information according to the characteristics of the region. In this case, the surface of the sidewalk block is printed by painting. There is a problem that the painted part is easily removed.

Therefore, recently, as shown in FIG. 15 , it has been proposed to fill the surface of the sidewalk block with resin to a certain depth so that it does not easily disappear even after a certain time has elapsed.

However, when molding such a sidewalk block, the contents to be realized on the bottom surface of the molding frame are partitioned so that the inner space is provided using an iron plate, etc. It becomes possible to implement by putting in and molding.

However, in this case, in order to implement variously changing patterns, there are difficulties in manufacturing, such as having different molds for each, and productivity deteriorates. There is going to be a downside.

The present invention is to solve the above problems, and it is possible to easily implement the patterns implemented in the pattern blocks in various forms according to the use or need, as well as to improve the product value by designing the patterns finely and precisely. This is to provide a pattern block that can be used.

In addition, it is possible to provide the above-mentioned patterns in the desired state by allowing various color classification or color flow expression, while also providing a non-slip function by utilizing the pattern patterns by these patterns.

To this end, the present invention provides a block manufacturing process for producing a concrete block body by putting a mixture containing aggregate into a molding die, molding the block body, and then curing;
After placing the block body in the cutting tool, the upper surface of the block body is driven in the X, Y, and Z axes by forming the engraved machining surface with a step difference and processing it into a set pattern to create an elaborate pattern, but A processing process that exposes the irregularities according to the characteristics of the aggregate to the processing surface;

It consists of a second molding step of press-pressing after filling the empty space of the molding mold by additionally injecting into the
In the processing process, the upper surface molded in the second molding step is processed into an intaglio by press-pressing with a second mixture to expose the unevenness molded by the first mixture into the processing surface formed with a step difference,
Pigment and silica sand are added to a resin containing at least one of urethane resin, epoxy resin, and polyester resin so that there is no risk of peeling by improving the adhesion with the block body composed of concrete with little shrinkage and expansion rate on the processing surface. , After the filler mixed with dolomite powder is filled, the desired pattern or color is realized during curing,
The filler inserts a filler having a relatively smaller capacity than the volume of the internal space in which the processing surface of the block body is formed so that the upper surface of the filler is filled to a relatively lower height than the upper surface of the block body.
In addition, the present invention is provided with a block body of concrete molded to be machinable while minimizing durability and surface pores by putting a mixture including aggregate into a molding mold and pressing in multiple stages,
The upper surface of the block body is formed with a stepped surface by a cutting tool, and the processing surface is engraved in a predetermined pattern to realize a pattern on the surface of the block, so that the unevenness according to the characteristics of the aggregate as a raw material is exposed as the processing surface. composed,
On the processed surface of the block body, there is a filler mixed with pigment, silica sand, and dolomite powder in a resin containing at least one of urethane resin, epoxy resin, and polyester resin so that there is no risk of peeling by improving adhesion with irregularities. A pattern is formed that is inserted to ensure adhesive durability,

According to the above drawing, the processing surface 140 in which the pattern 2 implemented on the upper surface 120 of the block body 100 constituting the block 1 is engraved is formed, and in this block (1) As a manufacturing method for realizing the pattern (2), as shown in FIG. 3, a block manufacturing process (S100) of curing the block after molding, a processing process of processing the pattern with an intaglio on the upper surface of the block (S200), It may be configured to include a painting process (S300) of painting a pattern processed by intaglio.

The block manufacturing process (S100) is produced by putting a mixture containing aggregate into a molding die, molding the block body 100, and then curing it, and the block body 100 is a mixture containing the aggregate to be composed of lightweight concrete. However, it can be produced by mixing concrete and liquid resin, or an artificial marble block produced by using liquid resin can be produced and used.

In addition, the processing step (S200) is a step of forming the processing surface 140 of the engraved pattern with a cutting tool (A) on the upper surface of the block manufactured in the block manufacturing process (S100). After positioning the cutting tool (A), the upper surface 120 of the block body 100 is processed to be indented with an end mill driven in the X, Y, and Z axes, and the machining surface 140 inserted as described above is cut It is possible to precisely implement the pattern 2 to be processed by forming an angled step.

And according to the characteristics of the aggregate, which is the raw material of the block body 100 , the bottom of the inner working surface 140 is exposed while being formed as the concave-convex surface 142 .
In addition, the color is applied to the processing surface of the block body through the painting process (S300) on the uneven surface 142 of the inner working surface 140 while the color is applied to the uneven surface 142 provided on the processing surface 140. Thus, it is possible to secure adhesion durability closely.

Therefore, by using the cutting tool (A) in the block body (100), various patterns (2) can be realized, and custom-made is possible while precisely manufacturing the design desired by the user, and high-quality colors are realized by the processing of the precise patterns. Since the falling pattern (2) can be expressed, it is possible to draw advertising and publicity effects for specific logos of local governments or companies.

On the other hand, in order to ensure that the color is closely adhered to the block body 100 to have durability, when the block body 100 is made of lightweight concrete, it is manufactured through the processes of raw material metering, raw material mixing, molding, and curing. In the raw material metering step, after selecting the aggregate according to the purpose of the block, the input amount is appropriately adjusted. In the raw material mixing step, the measured aggregate is mixed with cement and water and mixed, and the mixed mixture is placed in a mold. After being put and molded, the production of the block body 100 is completed through a curing step while applying heat for a certain period of time.

At this time, in the present invention, when molding the block body 100, the molding process is made in multiple steps to improve the durability of the block body 100 and to minimize pores on the surface on which the pattern is implemented. , for this purpose, as shown in FIG. 4, in the block manufacturing process (S100), a first molding step (S110) of partially filling a first mixture in a molding die and press-pressing, and a second mixture after the first molding step is molded By additionally injecting into the mold to fill the empty space generated in the first molding step, and then to include the second molding step (S120) of press-pressing, so that the production of the block body 100 of the present invention is made. can

And as this multi-step molding is made, it is processed into an intaglio as described above so that the concave-convex surface 140 on the bottom of the processing surface 140 has a relatively rougher surface than the surface (upper surface) of the block body 100. Can be implemented will be.

That is, when cutting the upper surface 120 of the block body 100 in an intaglio using a cutting tool to enter the lower side, the upper surface 120 molded by the second mixture is processed in an intaglio to make the machining surface angled. By making it possible to process it, it is possible to realize a fine pattern, and the uneven surface 142 formed on the bottom of the processed surface to be inserted in this way exposes the part molded by the first mixture, so that the relatively rough surface of the surface is exposed. After the uneven surface 142 is exposed to the bottom of the processing surface 140, the color is applied to the surface to facilitate penetration of the color applied to the pattern embodying the pattern, so that various colors of the pattern processed by intaglio The design can be diversified as the application of the coating becomes durable.

In addition, the cutting tool (A) is transferred while rotating using a cutting tool (TOOL) such as high-speed steel or cemented carbide in the form of a normal round bar to cut the upper surface 120 of the block body 100. The end mill can be controlled through a motor that can be driven in the Y and Z axes so that precise machining can be achieved, and the numerical control can be configured to be controlled manually or automatically through computer programming.

And, in the machining process (S200), when the end mill is in contact with the surface of the block body during machining, it is possible to perform sophisticated machining by machining in multiple stages using a cutting tool with different precision of the cutting tool.
For this purpose, as shown in FIG. 6 , the processing step ( S200 ) is performed by multi-step processing with different processing precision, thereby enabling processing of fine and sophisticated patterns.

That is, for example, the diameter of the cutting tool used in the end mill or the working flow is relatively large to perform the primary processing (S210) first, and then the diameter of the cutting tool used in the end mill is relatively small and the working flow is reduced. By performing the secondary processing (S220) to make the processing in detail, the shape of the angled part of the processing surface 140 of the upper surface 120 of the block body 100 is finely and precisely processed to improve the precise pattern quality. can

And, by processing in multiple steps in this way, it is possible to improve productivity and provide economical efficiency of the cutting tool, and to perform precise machining in which the machining surface has a gigantic angle.
In this way, it is possible to express color in various ways such as applying a color or urethane coating to the processed surface 140 that has been processed to be internalized. In the present invention, a primer application process of applying a primer to the processed surface to be internalized , it is possible to express the surface of the block body 100 in various textures and colors by performing a resin layer application process.

At this time, a curved surface 122 may be formed on the entire upper surface 120 of the block body 100 in order to add a non-slip function to the angled surface by the inner working surface 140, and this curved surface 122 ) can be expressed as atypical projections.

Therefore, when constructing the block 1 on the floor, the block 1 itself provides a non-slip function, as well as the portion where the block 1 and the pattern 2 are formed, that is, the upper surface 120 of the block body 100. Due to the differentiation of the processing surface 140 and the surface texture effect, it is possible to express a new aesthetic design.

On the other hand, the block body 100, as shown in Figs. 9 and 10, a filler 200 for implementing a pattern and color in the processing surface 140 formed to be inserted into the lower side on the upper surface 120, filling inserting By adding the process, the pattern can be made more vivid and colorful.

In the present invention, the filler 200 is filled with a pigment, silica sand, and dolomite powder in a resin containing at least one of a urethane resin, an epoxy resin, and a polyester resin, and then cured to implement a desired pattern.

At this time, since the urethane resin and the epoxy resin have a small shrinkage and expansion rate, the adhesion with the block body 100 made of concrete is improved, and there is little risk of peeling from the block body 100 even when used for a long period of time, and the desired color It is very easy to implement.

In addition, it is possible to implement various colors that do not change, and despite these advantages, because the manufacturing process is very simple, it can be manufactured at a relatively low cost, as well as because the block body 100 and the filler 200 are composed of a composite layer. Since the adhesion is made without empty space, the durability of the pattern can be further increased, and the strength of the block itself can be further improved because the release material is mutually supported.

At this time, the block body 100 can form the processing surface 140 by performing the processing step (S200) after first coating the surface with a specific color, and filling the block with the filler 200 in that state. It is possible to distinguish the surface coating color of the body 100 and the color of the filler 200 and implement the pattern in various designs.

In addition, the filler 200 inserts the filler 200 having a relatively smaller capacity than the volume of the internal space in which the processing surface 140 of the block body 100 is formed, so that the upper surface of the filler 200 is the block body 100 ) can be configured to be filled with a relatively lower height than the upper surface 120 .

That is, the filler 200 filled in the processing surface 140 is formed relatively lower than the height of the upper surface 120 , so that the upper surface 120 and the pattern 2 , that is, the filler 200 in the cured state of the filler 200 . ), it is possible to further provide a non-slip function due to the step difference by being configured with a step difference from the upper end.

Therefore, it is possible to add a non-slip function to the block 1 itself in the manufacturing process while simply implementing the pattern 2 on the block 1 in various designs.

In addition, in implementing the pattern by filling the processing surface 140 with the filler 200 as described above, the pattern can be implemented in various colors by forming a plurality of processing surfaces 140 and changing the color of each processing surface. have.

In addition, the filling process can further improve the aesthetics of design by filling the pattern 2 with a multi-color filling material on each processing surface 140 as shown in FIG. 11 .

In addition, the filling process may further include a decoration process for artistically expressing the filling material 200 filled in the processing surface 140 or giving a gradation.

That is, after filling the filler 200 as shown in FIG. 12 and before curing, a pattern tool or an air gun as shown in FIG. 13 is used to change the color arrangement or painting, so that the filler is filled. can be changed and more diverse designs can be implemented.

In addition, in implementing the pattern (2), when forming the processing surface 140, as shown in FIG. 14, by forming an inclined surface on one side to vary the inner depth as shown in FIG. 14, the color expression according to the thickness of the filler 200 is can make it happen.

For example, when filling with a resin of a transparent or translucent material, a difference in shading occurs due to a difference in thickness, and a three-dimensional effect or color expression may be configured differently. In addition to the method of forming the slanted surface 140, the same effect can be generated even when the processing surface 140 is formed in a multi-layer structure in which the processing depth is different from each other to form a step.
