Description

Concrete color structure with embossed patterns and construction method {Concrete Color Construct Sculptured Design and Method of Construction the Same}

The present invention relates to a concrete collar structure with an embossed pattern and a construction method thereof, and in particular, to have various types of embossed patterns, the color of the embossed pattern is different from the color of the ground surface, and the color is changed even when exposed to the natural environment for a long time. The present invention relates to a concrete collar structure having a high strength and a construction method thereof. The present invention also relates to an assembly structure in which such a concrete collar structure can be firmly assembled and the assembled portion can have a smooth surface.

In general, concrete buildings such as apartments, schools, religious buildings, public buildings, hotels, dormitories, hospitals, and shopping malls have protruding patterns with various shapes on the inner and / or outer walls of the building to improve the quality of the building. ), And the color of these embossed patterns and the base part was given. It gives a three-dimensional effect to concrete buildings, which makes them stand out in sophistication and is useful for advertisements and promotions as it is expressed in letters, pictures, and images. Typically, a pattern die is used to form an embossed pattern, and a method of painting paint is used as a method of imparting color.

However, as a method of imparting color, the paint can be variously expressed in letters or pictures, and thus various colors can be expressed. However, after a long period of time, the paint is peeled off and the color changes to deteriorate the dignity of the building. There was a problem.

Accordingly, in recent years, in order to improve the quality of the building, natural stone or artificial stone panels, such as marble, are attached to the exterior wall of the building, bricks are stacked, tiled, and the like. In addition, a dry bit method has been adopted in which a styropole is attached to the outer wall and a mesh is attached thereto to apply pigment plaster. However, this construction method has to be attached to the stone panels, bricks, tiles, etc. of natural or artificial stone at the site directly, so workability is poor and the construction period and the corresponding construction costs are considerably increased. Due to the weak bonding force with the wall, there was a problem of falling easily from the wall by the natural environment such as rain and wind.

In addition, as a method of forming an embossed pattern on the outer wall of the building and giving a color to the embossed pattern, a method of mixing and using a pigment in general concrete has been attempted. That is, the pigment was mixed with the general concrete kneaded with cement, aggregate (sand + gravel) and water, and placed in a pattern formwork. However, this is because the color is given to the concrete itself and the color is not changed or peeled off, but the embossed pattern and the base part have the same color, so that various colors cannot be expressed on one wall.

On the other hand, prefabricated building methods are mainly attempted to form walls of large buildings. In other words, the frame of the building was constructed using steel beams such as H-type, and then the plate-shaped concrete panels were fabricated prefabricated and attached to the frames, and the concrete panels were assembled to each other. At this time, the concrete panels are generally assembled by reinforcing bars protruding from the panel, and the assembled parts are finished again by concrete mortar. However, this method was not particularly smooth and robust in the assembled part.

Korean Unexamined Patent Publication No. 10-1999-0083968 discloses a prefabricated building concrete panel and a method of manufacturing the same. 1 and 2, the fine aggregate, water, and pigments are added to the mortar to form a mortar layer (1) with the mortar, and the general concrete is formed on the mortar layer (1). Prefabricated concrete panel and a concrete mortar layer 6 having a finishing mortar layer 6 after pouring a lightweight concrete layer 4 after installing a concrete layer (2), installing a wire and reinforcement (3) thereon The preparation method is shown. In addition, the assembly structure forms a "c" groove 6 on the panel and inserts a square pipe 7 into the "c" magnetic groove 6 so that the concrete panels are assembled by the square pipe 7. .

However, this is due to the use of the general cement and aggregate in the composition of the pigment mortar, the density of the color falls, and the shape of the pattern layer (1) cast with the pigment mortar did not overcome the limitation of the pattern formwork. That is, the color of the pigment itself was difficult to be clearly expressed due to the gray color of the general cement itself used as a binder and soil powder mixed in the general aggregate (sand). It was not possible to form a colorful pattern, and the pattern layer 1 was formed of ordinary cement concrete to which the pigment was added, and thus was not very good in terms of strength. In particular, since the concrete layer (2) is applied to the base portion around the glyph layer (1), the color should be painted as usual in order to give a color to the ordinary concrete layer (2). This happens. In addition, when the pattern layer (1) is a sculpture that represents a brick or marble, a joint is inevitably formed between a brick and a brick or a marble and a marble pattern. When applying mortar mixed with pigments on these joints, it is necessary to apply them in detail. Therefore, the problem of air and labor cost increase, and when inadvertently applied to brick or marble patterns, the image of brick or marble patterns is removed by the color of mortar. There was an inconvenience in working.

In addition, in the assembly structure, the concrete panels are simply fitted together by the square pipes 7 inserted into the “c” grooves 6, so that they are not firm and in particular, the corresponding force due to the horizontal force is insufficient.

The present invention has been invented to solve the problems of the prior art as described above, the color of the pigment appears clearly while having a variety of embossed patterns, the color of the embossed pattern and the color of the base surface is different, It is an object of the present invention to provide a concrete collar structure with an embossed pattern having no color change even when exposed to the environment, and a construction method thereof.

In addition, the present invention improves the binding force between the embossed pattern and the concrete particles forming the base surface to have a high surface strength to emboss the concrete collar structure formed with an embossed pattern that can be prevented from being damaged by scratching or natural weathering and its construction method There is another purpose in providing it.

Another object of the present invention is to be assembled so that the concrete collar structure can be assembled to the frame or other concrete structure and the concrete collar structure interlocking with each other, the assembly is solid, the assembled portion is embossed pattern is formed having a smooth surface To provide a concrete collar structure and its construction method.

It provides a construction method of a concrete collar structure formed with an embossed pattern made by.

The base layer is a main skeleton of the concrete collar structure may be a general concrete layer, lightweight foam concrete layer, glass fiber concrete layer or a combination thereof.

The general concrete layer is formed by pouring general concrete mortar (base mortar) mixed with cement (portland cement, etc.), aggregate (sand + gravel) and water on the base layer. At this time, after reinforcing the mesh (wire mesh) or reinforcing bar to prevent cracking of the concrete collar structure and reinforcing strength on the base layer, the general concrete mortar is poured and the mesh (wire mesh) or reinforcement is embedded in the general concrete layer.

The lightweight foamed concrete layer is formed by pouring lightweight foamed concrete mortar (base mortar) mixed with cement, foaming agent and water onto the base layer. At this time, after the reinforcement of the mesh (wire mesh) or rebar on the base layer, the lightweight foam concrete mortar is poured and the mesh (wire mesh) or rebar may be embedded in the lightweight foam concrete layer.

The glass fiber concrete layer is made of glass fiber, cement and sand. The glass fiber concrete layer is preferably formed by spraying a glass fiber strip on the base layer and simultaneously spraying (mortar) concrete mortar mixed with cement, sand, and water, while performing roller compaction to firm the structure. . In such a glass fiber concrete layer, reinforcing materials such as mesh (wire mesh) or reinforcing bars are not embedded.

In addition, the present invention is a prefabricated structure of the metal assembly formed with a separation prevention portion and groove in the base layer so as to be firmly assembled with the frame of the building (steel beam, etc.) or other concrete structure or concrete collar structure according to the present invention. Provide concrete collar structures. The metal assembly tool is fitted into the recessed structure formed in engagement with the metal coupling member having a fitting portion corresponding thereto.

The silica sand used in the present invention is a finely pulverized white silicate mineral in the usual sand size. Such silica can be easily purchased at glass manufacturing plants.

In addition, the pigment is a colorant (pigment) that can make a color including a dye and an inorganic / organic pigment, and the like, for example, azo dye, anthraquinone dye, carbon black, iron oxide, pigment yellow (pigment yellow), etc. It is a coloring agent used alone or mixed two or more kinds so that a desired color comes out. In this case, a pigment having a different color is used for the pattern pigment mortar and the ground pigment mortar.

Therefore, the concrete color structure according to the present invention improves the dignity of the building by imparting a visual appeal and aesthetic beauty by expressing different colors on the embossed glyph layer and the base layer, and the pigment for expressing the color is mixed with the mortar itself It does not peel off or deteriorate even after a long period of time like a conventional paint coating. Particularly, the pattern pigment mortar and the ground pigment mortar use white cement and white silica sand, and the color of the pigment is clearly expressed as it is and has high surface strength.

In addition, according to another embodiment of the present invention, the pattern pigment mortar and the base pigment mortar for forming the embossed pattern layer and the base layer may use a polymer pigment mortar in which white cement, polymer resin, silica sand, pigment, and curing agent are mixed. .

In the present invention, "concrete collar structure" is a concrete concrete structure having a color of prefabricated and integrally built buildings, such as houses, apartments, schools, wedding halls, religious buildings, day care centers, public buildings, hotels, dormitories, hospitals, mall buildings, etc. Walls, walls of mobile assembled buildings (typically 'containers'), such as prefabricated offices or houses, columnar concrete structures for advertising promotion, and monuments in the form of people or animals (ordinary 'statues') ), Retaining wall around the stadium, and the like. The concrete collar structure according to the invention is particularly useful for walls of prefabricated buildings having a panel shape so that they can be assembled to the framework of the building or other concrete structures and to the concrete collar structure according to the invention.

And, in the present invention, "embossed pattern" is a three-dimensional character, figure, image formed by protruding the inner wall and / or outer wall of the concrete collar structure, for example, hemispherical shape, triangular, square, pentagonal, octagonal half of the ball Polygonal shape such as, rhombus with a vertex in the center, brick shape, marble shape, flower, animal, figure, cross, bell, bird, tree, rainbow, waterfall, mountain, car, plane, It includes three-dimensional shapes of trains, buildings, and plants.

Hereinafter, with reference to the accompanying drawings will be described in detail the concrete collar structure and the construction method of the embossed pattern of the present invention.

Referring to Figure 3, as an example of the concrete collar structure according to the present invention in order to construct a panel-shaped concrete collar structure having a panel (panel) shape of the rectangular formwork 50 having a rectangular bottom surface 51 is Used. A hole 52 is drilled in the bottom of the formwork 50, and the embossed mold 55 is coupled to the hole 52 by welding or bolting. At this time, a plurality of holes 52 of the formwork 50 may be formed according to the number of embossed patterns, the embossed pattern mold 55 coupled to these holes 52 is a plurality of embossed patterns having different shapes 55 may be combined. Therefore, a plurality of embossed patterns having a form 50 and having different shapes may be formed.

In the drawing, two holes 52 are formed, an embossed pattern mold 55 capable of forming a hemispherical embossed pattern, and an embossed pattern mold 55 capable of forming a rhombic embossed pattern with a vertex protruding from the center thereof. Illustrated is the formwork 50 to be combined. When the embossed pattern is a brick or marble shape, a plurality of holes 52 and embossed molds 55 of the formwork 50 are formed. The material of the formwork 50 and the embossed pattern mold 55 is not particularly limited, but metal, synthetic resin, wood, gypsum, and the like may be used. In addition, the die 50 and the embossed mold 55 may be injection molded integrally using metal or synthetic resin.

Referring to Figure 4, the bottom surface 51 is covered with a blocking means such as vinyl, cloth or iron plate so that the pattern pigment mortar does not adhere to the bottom surface 51 of the formwork 50 as described above. The reason for covering the blocking means is to prevent the pattern pigment mortar and the ground pigment mortar from mixing with each other at the bottom 51 portion of the formwork 50. In such a blocking means, a hole corresponding to the hole 52 of the formwork 50 is formed so that the pattern pigment mortar is poured into the relief pattern mold 55. In this state, the pattern pigment mortar for forming the relief pattern layer 10 is poured by a method of spraying several times. The pattern pigment mortar is a mixture of white cement, silica sand, pigment and water. The pigment may be mixed with 0.5 to 10 parts by weight based on 100 parts by weight of the white cement, and may vary depending on the brightness of the desired color. And the mixing ratio of white cement and silica sand is as usual.

When the pattern pigment mortar becomes somewhat initial curing (not completely hardened), the base pigment mortar for removing the blocking means and forming the base layer 20 to a predetermined thickness on the bottom surface 51 of the formwork 50 Is poured. The reason why the ground pigment mortar is poured at the time when the pattern pigment mortar is not completely cured and the initial curing time is that the pattern pigment mortar and the ground pigment mortar are bonded to each other in a state that is not hardened. ) Is integrally combined. In this case, when the size of the embossed glyph layer 10 is large, a mesh (wire mesh) or rebar may be installed to reinforce the strength of the embossed glyph layer 10 and prevent cracking. Background pigment mortar is a mixture of white cement, silica sand, pigments and water, wherein the pigment used is a different color than the pigment used in the pattern pigment mortar. The silica sand is finely pulverized white mineral silica to the size of ordinary sand.

When the base pigment mortar becomes somewhat initial curing (not completely hardened), base mortar for forming the base layer 30 is poured thereon.

The base layer 30 may be a single layer selected from a general concrete layer, a lightweight foam concrete layer, a glass fiber concrete layer, or a combination thereof.

The general concrete layer is formed by pouring a general concrete mortar (base mortar) mixed with cement, sand, gravel and water on the base layer 20. At this time, the mesh (wire mesh) or reinforcing bar is installed on the base layer 20 to prevent cracking of the concrete collar structure and reinforce the tensile force before placing the general concrete mortar. Therefore, a mesh (wire mesh) or rebar is embedded in the general concrete layer.

In addition, the lightweight foam concrete layer is formed by pouring a lightweight foam concrete mortar (base mortar) mixed with cement, foaming agent and water on the base layer 20. A foaming agent can use aluminum powder etc. as usual. This lightweight foamed concrete layer has a number of pores formed inside the concrete substrate to have a light weight and insulation.

At this time, the mesh (wire mesh) or reinforcing bar may be installed on the base layer 20 before pouring the lightweight foam concrete mortar. Therefore, a mesh (wire mesh) or rebar may be embedded in the lightweight foam concrete layer.

And, the glass fiber concrete layer is a glass fiber (glass fiber), cement and sand are mixed and cured. The glass fiber concrete layer is sprayed (spray) the concrete mortar mixed with cement, sand, and water while spraying a glass fiber strip on the base layer 20 to prevent the glass fibers from agglomerating. It is preferable to form by performing roller compaction to be firm. The glass fiber concrete layer is reinforced by the glass fiber to prevent cracking and strength of the concrete collar structure, and can be constructed in a thin thickness of the concrete collar structure. Therefore, when the base layer 30 is composed of a glass fiber concrete layer, since the glass fiber has sufficient strength, the mesh (wire mesh) or the reinforcing bar is not embedded.

For example, in the case where the base layer 30 is a multi-layered structure in which a general concrete layer, a light foamed concrete layer, and a glass fiber concrete layer are combined, a glass fiber concrete layer is formed on the base layer 20, and a glass fiber concrete layer Lightweight foam concrete layer can be formed on it. As such, when the base layer 30 is made of a glass fiber concrete layer and a light foamed concrete layer, the glass fiber concrete layer has excellent strength, and the light weight foam concrete layer can achieve a lighter weight compared to the thickness and can have insulation. Here, when the base layer 30 is composed of two layers of glass fiber concrete layer and lightweight foamed concrete layer, the glass fiber concrete layer has sufficient strength, so that the lightweight foam concrete layer has a light weight screen of the concrete collar structure 100. It is preferable not to embed a mesh (wire mesh) or rebar.

In addition, according to the present invention, in order to impart even higher surface strength to the relief pattern layer 10 and the base layer 20, the pattern pigment mortar and the base pigment mortar may be used as the polymer pigment mortar. The polymer pigment mortar is a mixture of white cement, polymer resin, silica sand, pigments and curing agents.

The polymer resin used for the polymer pigment mortar is a thermosetting resin, and is specifically selected from unsaturated polyester resins, epoxy resins, polyurethane resins and acrylate resins. Preferably, an unsaturated polyester resin having good bonding strength, fast curing speed, and low cost with white cement and silica sand is used. Further, the curing agent may be a fast curing type, a standard curing type or a delayed curing type, but is preferably a standard curing type as a peroxide-based compound such as methyl ethyl ketone peroxide suitable for an unsaturated polyester resin. Use

The polymer pigment mortar has a waterproof, durable and chemical resistance in the relief pattern 10 and the base layer 20. And by improving the bonding strength of the concrete particles to have a higher surface strength to prevent the embossed glyph layer 10 or the base layer 20 is damaged by scratching or natural weathering.

After forming the relief pattern 10, the base layer 20 and the base layer 30 as described above, the finishing layer 40 may be formed on the base layer 30. The finishing layer 40 is formed by bonding a conventional finishing member (tile, etc.) or plastering concrete mortar mixed with cement, sand, and water to have a flat surface.

Plastering concrete mortar for forming the finishing layer 40 as described above, but not particularly limited, after curing for about 24 hours at a curing temperature of 60 degrees, demolding the formwork 50 according to the present invention 10, the base layer 30, the base layer 30 and the plaster layer 40, the concrete collar structure 100 (see Fig. 9) is integrally constructed.

On the other hand, as another construction method of the concrete collar structure 100 according to the present invention as described above, the embossed glyph layer 10 may be molded separately to be coupled to the concrete collar structure 100. That is, after the embossed glyph layer 10 is molded separately from the embossed glyph mold 55, the embossed glyph layer 10 is temporarily fixed by being inserted into the hole 52 of the formwork 50.

The base layer 20 and the base layer 30 are formed in the same manner as described above. At this time, since the embossed glyph layer 10 and the base layer 20 are not integrally bonded (initial curing coupling), the embossed glyph layer 10 and the concrete collar structure 100 are firmly coupled to the embossed glyph layer 10 ) And a metal connecting member 35 such as reinforcing bars are embedded in the base layer 20 and the base layer 30. That is, in the process of separately forming the embossed glyph layer 10, one side of the metal connecting member 35 is embedded in the inside of the embossed glyph layer 10, and the other side is buried in the formation of the base layer 30.

As such, the method of separately forming the embossed glyph layer 10 to be coupled to the concrete collar structure has an advantage that one formwork 50 can be used several times. That is, there is an advantage that can be used by fixing several embossed glyph layers 10 having different shapes to the formwork 50 times.

In addition, with reference to Figure 5 when the shape of the concrete collar structure 100 according to the present invention is a columnar shape that can be used for advertising will be described as follows.

As described above, the die 50 has a hole 52 formed therein, and an embossed mold 55 is coupled to the hole 52. Then, covering the blocking means on the bottom surface 51 of the formwork 50, the patterned mortar is poured to form an embossed pattern layer (10).

In addition, after removing the blocking means, the base pigment mortar for forming the bottom base layer 20 is poured, and then the blocking film 60 is installed on both sides of the formwork 50. In this state, the base pigment mortar for forming the base layer 20 on both sides is poured between the barrier layer 60 and the sidewalls of the formwork 50, and between the barrier layer 60 on both sides (that is, the center of the formwork 50). Part) base mortar for forming the base layer (30). Then, the barrier layer 60 is immediately removed or the barrier layer 60 is removed when the base layer 20 and the base layer 30 become initial curing to some extent. After removing the barrier layer 60 as described above, the base pigment mortar for forming the base layer 20 on the upper part is poured. Here, the composition of the relief pattern layer 10, the base layer 20 and the base layer 30 is as described above.

Therefore, as shown in FIG. 6 showing the columnar concrete collar structure 100 constructed as above, an embossed glyph layer 10 is formed on one surface thereof, and has a different color from the embossed glyph layer 10. The base layer 20 is formed. And the background color of each side can be made the same. In addition, the four letters "development of Youngsan" represented in Figure 6 may be different in color depending on the choice of the pigment of the pattern pigment mortar.

The concrete collar structure 100 according to the present invention described above can be assembled by having a panel-like construction to have an assembly structure as usual. For example, the concrete collar structures 100 may be assembled to each other by forming a "c" -shaped groove on the sidewall or forming a stepped groove by the "b" -shaped. However, it is desirable to have the assembly structure described below so that the framework of the building or the concrete collar structure 100 can be firmly assembled to each other.

Hereinafter, the prefabricated concrete collar structure 100 provided by the present invention will be described.

Referring to Figure 7, the metal assembly 70 is embedded in the concrete collar structure 100 to be a solid assembly structure in accordance with the present invention is the separation prevention portion 72 on one side, and the groove portion 75 on the other side. Consists of, the other end is formed integrally with the locking projections 76 extending into the groove portion 75 inside. This metal assembly 70 is embedded in the base layer (30). That is, the metal assembly tool 70 is embedded in the base layer 30 by installing the metal assembly tool 70 on the base layer 20 and then pouring the base mortar. In addition, a plurality of concave holes 70a may be formed in the metal assembly 70 so that concrete particles may be inserted to improve the bonding force with the base layer 30 and reduce the weight. Prefabricated concrete collar structure according to the present invention is such a metal assembly 70 is buried in any one or two or more sides of the frame of the building (steel beam, etc.) or other concrete structures or concrete collar structure according to the present invention It can be assembled firmly.

At this time, the metal coupling sphere 80 is fitted into the assembly structure to engage the metal assembly sphere 70 is used. This metal coupler 80 is illustrated in FIGS. 7 and 8.

As shown in FIG. 7, the metal coupler 80 includes a fitting portion 85 fitted to the recess 75 of the metal assembly 70 and a fixing portion 82 fixed to a frame or other concrete structure of a building. Is done. The metal coupler 80 illustrated in FIG. 8 illustrates a state in which the insertion hole 86 is formed so that the pipe can be inserted into the fitting portion 85. That is, an electric wire, a cable, or the like is installed in the pipe, and the pipe is inserted into the insertion hole 86 so as to be used as a passage for the electric wire, the cable, and the like. The metal coupler 80 shown in FIG. 7 exemplarily has a cross section of "H" shape, and FIG. 8 illustrates a cross section of "o" shape.

In addition, the prefabricated concrete collar structure 100 according to the present invention may be embedded with a metal coupler 80 as illustrated in FIGS. 7 and 8. This is particularly desirable when the prefabricated concrete collar structures 100 are assembled together.

The method of assembling the concrete collar structure 100 having the metal assembly tool 70 and the metal fitting member 80 as described above will be described with reference to FIG. 9.

First, in the case of assembling the concrete collar structure 100 in which the metal assembly 70 is embedded according to the present invention with another structure, for example, the frame 90 of a building, the fixing portion 82 of the metal coupling member 80 is provided. ) Is coupled to the framework 90 by welding or bolting. 9 illustrates the H-type steel beam as the frame 90 of the building. After inserting the fitting portion 85 of the metal coupler 80 into the recessed portion 75 of the metal assembly 70, the recessed portion 75 is filled with a hardened concrete mortar.

Therefore, the metal assembly 70 is not separated from the concrete collar structure 100 by the separation preventing portion 72 formed therein, and the fitting portion 85 of the metal coupling member 80 is cured non-condensed concrete mortar. It is fixed to the groove portion 75 of the metal assembly 70 by, and the hardened non-condensed concrete mortar is not separated by the locking jaw 76 so that the frame 90 and the concrete collar structure 100 is engaged with each other structure Are firmly combined. Polymer concrete mortar may be used instead of the non-condensed concrete mortar used for the combination of the metal assembly 70 and the metal coupler 80.

In addition, when assembling the concrete collar structure 100 on both sides of the frame 90, a conventional heat insulating material may be filled between the concrete collar structure 100. As such, when assembling the concrete collar structure 100 on both sides of the frame 90, in particular, the base layer 30 may be composed of a glass fiber concrete layer to reduce the thickness of the building wall with insulation.

In addition, the metal coupler 80 shown in FIGS. 7 and 8 may be embedded in the concrete collar structure 100 according to the present invention and assembled with each other. That is, as shown in FIG. 9, the concrete collar structure 100 according to the present invention may have a metal assembly tool 70 embedded in one side and a metal coupler 80 embedded in the other side. At this time, the fixing portion 82 of the metal coupler 80 is embedded in the base layer 30. The method of assembling the concrete collar structure 100 is the same as the method of assembling with the frame 90 described above, the joint between the concrete collar structure 100 is applied by finishing the base pigment mortar finish. Preferably, the base pigment mortar is used by further adding a waterproofing liquid within a range that does not change the color of the pigment. Therefore, the concrete collar structure 100 is assembled by the metal assembly 70 and the metal coupler 80, the assembled portion has a smooth surface. This is much simpler than the conventional construction method of connecting the reinforcing bar and installing formwork in this part to finish the concrete mortar, and is firmly assembled.

The shape of the prefabricated concrete collar structure 100 described above is most preferably a panel type. However, it is also applicable to the columnar shape shown in FIG. That is, referring to Figure 6, in the construction process of the columnar concrete collar structure 100 without forming the upper base layer 20 (see Fig. 5), the recessed portion of the metal assembly (70) The metal coupling hole 80 may be fixed to the wall of the building by embedding the base layer 30 in a process of placing the base layer 75 upward, and then assembling and bonding may be performed as described above.

On the other hand, in the present invention has been described as the embossed glyph layer (10) and the part that the pattern is expressed and protruding the base layer 20, but on the contrary, the part where the glyph is expressed is formed in the intaglio Even if the layer 20 is protruded will be included in the present invention. That is, in this case, the term 'embossed glyph layer' used in the present invention will be the base layer and the 'background layer' will be the intaglio glyph layer.

Therefore, the present invention improves the dignity of the building by giving different colors to the embossed glyph layer 10 and the base layer 20 to give a visual appeal and aesthetic beauty, and the pigment for expressing the color is mixed in the mortar itself It is possible to maintain the color for a long time because it does not peel off or deteriorate even after a long time like conventional paint coating. Particularly, the pattern pigment mortar and the ground pigment mortar are preferably applied to a building in which aesthetics are important because white cement and white silica sand are used so that the color of the pigment is clearly expressed and has a high surface strength.

In addition, when the embossed glyph layer 10 and the base layer 20 are formed of polymer pigment mortar according to the present invention, the embossed glyph layer 10 and the base layer 20 have waterproofness, durability and chemical resistance, and the like.
