The concrete body 11 is formed in a plate shape with a constant thickness. In the illustrated example, the concrete body 11 is shown to have a rectangular shape, but, of course, it may be formed in various shapes such as a circle, a triangle, and a pentagon.

The concrete body 11 can be manufactured in a certain shape by injecting concrete into a formwork to cure it, and then removing the formwork.

The intaglio pattern 13 is formed on one surface of the concrete body 11 . The intaglio pattern 13 is drawn into a predetermined depth from one surface of the concrete body 11 to form a groove. The depth of the intaglio pattern 13 may be 1 to 5 mm.

In the illustrated example, a picture of a plant in the shape of a engraved pattern 13 is illustrated, but in contrast to this, various patterns such as numbers, letters, and symbols may be applied.

The color pattern member 15 is formed in a shape corresponding to the intaglio pattern. The color pattern member 15 may be formed of various materials such as synthetic resin, metal, wood, and paper. The color pattern member 15 is inserted into the intaglio pattern 13 and fixed.

Meanwhile, FIG. 5 shows a color pattern concrete panel 20 to which characters are applied as a color pattern member 50 .

Hereinafter, as an example of the method of manufacturing the colored patterned concrete panel of the present invention, a method of manufacturing the colored patterned concrete panel 20 of FIG. 5 will be described.

5 to 12, the method of manufacturing a color pattern concrete panel according to an example of the present invention includes a first step of manufacturing a concrete body 21 formed by inserting an intaglio pattern 5 on one surface to a certain depth; , a second step of inserting and fixing the color pattern member 50 having a shape corresponding to the intaglio pattern 5 into the intaglio pattern 5 . Let's look at each step in detail.

1. Step 1

The first step is a process of manufacturing the concrete body 21 on which the intaglio pattern 5 is formed.

This first step includes a formwork preparation step of preparing the formwork 100 having an embossed pattern 3 formed on the inner surface, a pouring step of pouring concrete into the formwork 100 and pouring, and the concrete injected into the formwork 100 . A curing step of hardening, a form removal step of removing the formwork 100 to obtain a concrete body 21 having an intaglio pattern 4 corresponding to the embossed pattern 3 formed on one surface, and an intaglio pattern 4 and Attaching the cover sheet 30 on which the corresponding cut-out pattern 7 is formed to one side of the concrete body 21 to cover the rest of the area except for the intaglio pattern 4, and to one side of the concrete body 21 It includes a blasting step of cutting the intaglio pattern 4 deeper by spraying particles, and a cover sheet separation step of separating the cover sheet 30 from the concrete body 21 .

In the first step, the intaglio pattern is divided into before the blasting step and after the blasting step. The engraved pattern before the blasting step is denoted by reference numeral '4', and the engraved pattern after the blasting step is denoted by the reference numeral '5'. The intaglio pattern of reference numeral '5' is different in that it is formed deeper than the intaglio pattern of reference numeral '4'.

(1) Form preparation stage

First, the formwork 100 for molding the concrete body 21 is prepared.

The formwork 100 has an inner space corresponding to the shape of the concrete body 21 . The formwork 100 may be made of metal, synthetic resin, wood, or the like. As the formwork 100, a conventional Euroform can be assembled into a box shape and used.

An embossed pattern 3 is formed on the inner surface of the mold 100 as shown in FIG. 7 . The embossed pattern has a shape corresponding to the engraved pattern.

The embossed pattern 3 is formed to protrude from the inner surface of the mold 100 . The embossed pattern 3 may be made of wood or synthetic resin. The embossed pattern 3 may be made separately from the mold 100 and attached to the inner surface of the mold 100 . And the embossed pattern 3 may be made integrally with the mold 100 itself.

In the illustrated example, the characters are exemplified as the embossed pattern 3, but otherwise, various patterns such as numbers, symbols, and pictures may be applied.

(2) pouring stage

Next, concrete is poured into the formwork 100 and poured.

You can prepare concrete by mixing cement with sand and water, or you can prepare concrete by mixing cement with sand, gravel, and water.

(3) Curing stage

Next, the concrete injected into the formwork 100 is hardened.

Curing may be carried out in a conventional manner. For example, it may be naturally dried for about 5 to 30 days.

(4) Form removal step

Next, the mold 100 is removed to obtain a cured concrete body 21 as shown in FIG. 8 . The concrete body 21 is formed in a plate shape with a constant thickness.

An intaglio pattern 4 is formed on one surface of the cured concrete body 21 . This engraved pattern (4) is made in a form corresponding to the embossed pattern (3). The intaglio pattern 4 is formed by entering a predetermined depth from the surface of the concrete body 21 . The depth of the intaglio pattern 4 may be 0.5 to 3 mm.

(5) Cover sheet attachment step

Next, as shown in FIG. 9 , the cover sheet 30 is attached to one surface of the concrete body 21 .

The cover sheet 30 may be formed to be the same as or larger than the size of one surface of the concrete body 21 so as to cover one surface of the concrete body 21 . The cover sheet 30 may be formed of a synthetic resin material having excellent strength and durability. The cover sheet 30 serves to protect the remaining area except for the area of the intaglio pattern 4 in the blasting step to be described later.

A cutout pattern 7 corresponding to the intaglio pattern 4 is formed on the cover sheet 30 . The cover sheet 30 is cut out in a shape corresponding to the intaglio pattern 4 to form a cutout pattern 7 on the cover sheet 30 .

When the cover sheet 30 is attached to the concrete body 21 , the positions of the cutout pattern 7 and the intaglio pattern 4 match. Therefore, the cover sheet 30 covers the remaining portion except for the intaglio pattern (4).

In order to attach the cover sheet 30 to the concrete body 21 , an adhesive may be applied to one surface of the concrete body 21 . A conventional polymer binder may be used as the adhesive. In addition to the attachment method using an adhesive, the cover sheet 30 may be fixed to the concrete body 21 using a separate fixing tool.

(6) Blasting step

Next, blasting is performed by spraying particles on one surface of the concrete body 21 as shown in FIG. 10 .

In blasting, particles such as sand or steel balls are sprayed on the surface of an object to grind or scrape the surface of the object. Sand blasting or shot blasting may be applied to the blasting in the present invention.

When the nozzle (1) of the blast machine is directed toward the intaglio pattern (4) and then the particles are sprayed, the intaglio pattern (4) is cut deeper while the particles collide with the intaglio pattern (4) of the concrete body (21). At this time, since the cover sheet 30 is covered around the intaglio pattern 4, only the intaglio pattern 4 portion is cut.

After blasting, an intaglio pattern 5 having a deeper depth is formed as shown in FIG. 11 . After blasting, the depth of the intaglio pattern 5 may be 1 to 5 mm.

(7) Cover sheet separation step

Next, the cover sheet 30 is separated from the concrete body 21 .

When the cover sheet 30 is removed, the production of the concrete body 21 having the intaglio pattern 5 formed on one surface is completed.

On the other hand, in the present invention, as another example, the curing step may be performed by a method of delaying the curing of the concrete around the embossed pattern.

Referring to FIG. 13 , the injection pipe 40 is installed in the formwork 100 . The injection pipe 40 is installed to penetrate from the outside of the mold 100 to the inside. The injection pipe 40 installed in the mold 100 extends into the embossed pattern 3 and is connected to the embossed pattern 3 .

The illustrated embossed pattern 3 has a main flow path 43 and a sub flow path 45 formed therein.

The main flow path 43 is formed to be long left and right or front and rear. The main flow path 43 is formed adjacent to the surface of the embossed pattern (3). The main flow path 43 is connected to the end of the injection pipe 40 . Therefore, when the curing retardant is injected through the injection pipe 40 , the curing retardant is introduced into the main flow passage 43 .

The sub-channel 45 is formed by branching from the main flow passage 43 . The sub-channels 45 may be formed side by side at regular intervals. The end of the sub-channel 45 extends to the surface of the embossed pattern 3 and is exposed to the outside of the embossed pattern 3 .

After inserting the supply nozzle 2 into the injection tube 40 , the curing retardant is injected into the injection tube 40 . The curing retardant 9 may be injected into the injection tube 40 immediately after pouring or at the beginning of curing.

As the hardening retardant 9, a conventional liquid cement hardening retarder may be used. The curing retardant 9 injected through the injection pipe 40 flows into the main flow path 43 and flows out of the embossed pattern 3 through the sub flow path 45 . At this time, the curing retardant 9 leaked to the outside of the embossed pattern 3 flows out to the area where the surface of the embossed pattern 3 and the concrete 25 before curing are in contact, delaying the hardening of the concrete around the embossed pattern 3 make it

Accordingly, after curing for a certain period of time, the concrete strength of the portion in contact with the surface of the embossed pattern 3 is weaker than the concrete strength of other portions. Therefore, when blasting is performed on the intaglio pattern formed on the concrete body after curing, it is relatively easy to cut the intaglio pattern.

2. Step 2

The second step is a process of inserting and fixing the color pattern member 50 having a shape corresponding to the intaglio pattern 5 into the intaglio pattern 5 as shown in FIG. 12 .

The color pattern member 50 may be prepared in various ways. For example, when using a fabric made of paper or plastic material, a color pattern member can be obtained by cutting the fabric into a shape corresponding to the intaglio pattern. In addition, a color pattern member can be obtained by injection using a mold having a cavity having a shape corresponding to the intaglio pattern. In addition, a color pattern member can be obtained by processing a thin plate of a metal material into a shape corresponding to the intaglio pattern.

When the color pattern member 50 is prepared, it is inserted into the intaglio pattern 5 and fixed. To this end, an adhesive may be applied to one surface of the color pattern member 50 before the color pattern member 50 is inserted into the intaglio pattern 5 , or an adhesive may be applied in advance to the inside of the intaglio pattern 5 .

After the color pattern member 50 is inserted into the intaglio pattern 5, when the adhesive is cured, the color pattern concrete panel 20 of the present invention is completed.

And it goes without saying that the color pattern concrete panel can be manufactured by applying the color pattern member 15 shown in FIG. 2 to the above-described manufacturing method.

As mentioned above, although the present invention has been described with reference to one embodiment, it will be understood that this is merely exemplary, and that those skilled in the art may make various modifications and equivalent embodiments therefrom. Therefore, the true protection scope of the present invention should be determined only by the appended claims.
