In the following, the medium-large size is used to mean a sculpture that is larger than the size of a general kiln for baking, and the small size is used to mean a size that can be baked in a kiln smaller than the size of the kiln for baking. do.

1 is an exemplary view showing a manufacturing process of medium-large clay sculptures larger than the size of the kiln according to the present invention, the present invention is a design step for modeling and drawing a clay shape of a smaller size than the clay sculpture to be produced (10 ) And a clay clay brick manufacturing step 20 for kneading a clay brick raw material including clay to form a clay sculpture, and manufacturing a clay clay brick 100 having a desired size, and the clay clay brick 100 Sculpture object forming step (30) of stacking to form a sculpture object, a wet sculpture forming step (40) to form a wet sculpture by carving in the shape of the clay sculpture to express the sculpture object and the sculpture of the wet sculpture The wet molded object dismantling step 50 of dismantling the molding clay brick 100 in units of serial clay bricks 100 and writing each of the dismantled clay bricks 100 And calcining step (60) for firing in a kiln after, include making sure that the serial number of the sintered molding clay 100 masonry reassembled into the clay-like sculptures reassembly step 70.

The design step (10) is to model the clay sculpture to be produced in the clay shape of 1/100 to 1/3 size, and to produce a drawing for the clay sculpture based on the modeled clay shape and the size of the molded clay brick Is made of decisions.

In other words, the design step (10) is to design the relief of the three-dimensional shape or the relief of the unique shape of the sculpture and the three-dimensional sculptures in accordance with the demands of the consumer by computer graphics, and model it as a small clay shape In this case, the modified and supplemented design drawings are produced through modeled clay sculptures. The clay shape is preferably modeled in a size of 1/100 to 1/3 smaller than the clay shape, and a drawing about the clay shape is made based on the modeled clay shape and the size of the molded clay brick 100 is determined. .

The molded clay brick manufacturing step 20 is a process for producing a clay clay brick of the desired size by kneading the clay brick raw material containing clay, the clay brick raw material is made by grinding after mixing clay, red clay, kaolin After mixing, and mixing 15 to 20 parts by weight of water with respect to 100 parts by weight of the clay brick raw material is to prepare a molded clay brick of a predetermined size.

In addition, the clay brick raw material is composed of 5 ~ 30wt% clay, 10 ~ 50wt% red clay, 30 ~ 80wt% kaolin pulverized to less than or equal to 3mm size and mixed.

Meanwhile, in order to increase the efficiency of drying and sintering the molded clay brick during the manufacture of the molded clay brick, 10 to 40 parts by weight of inorganic material may be further mixed.

The inorganic material is effective for drying and calcining, and may use one or more of the group consisting of feldspar, loess, masato, fly ash, stone powder, waste coal, and inorganic sludge.

The present invention is to reduce the molding clay brick temperature and increase the strength of the molded clay brick by the addition of the inorganic material configured as described above in the manufacture of the molded clay brick.

The inorganic pigment may be used at least one selected from the group consisting of color oxides iron oxide, titanium dioxide, manganese oxide and chromium oxide.

On the other hand, during the production of the molded clay brick 100, it may be extrusion molded using an extruder (extruder) used in the general clay brick manufacturing plant.

In addition, the clay column extruded from the extruder is cut by using a thin line such as a piano wire so as to meet the required standard to form a molded clay brick (100).

The molded clay brick 100 produced as described above preferably has a residual ratio (distribution rate of a raw material having a particle size of 100 mesh or more) of 20 to 35%.

This means that if the residual ratio is 20% or less, the discharge load of the extruder is increased to damage the extruder, and the molding clay brick 100 is dried and shrinked in the firing process, resulting in deformation and cracking, and the residual ratio is 35%. When exceeded, the mold of the extruder is damaged to shorten the life of the machine, and the firing temperature of the molding clay brick 100 is increased to increase energy consumption and lower the strength of the final product.

In addition, the hardness of the molded clay brick 100 is preferably 1.5 ~ 2.5kgf / cm ² measured by a penetrometer (penetrometer).

This hardness is 1.5kgf / cm ² or less when moldability (plasticity plasticity) away it is difficult to maintain a model for forming a sculpture, 2.5kgf / cm ² molding clay 100 is above the molding clay 100 This is because there is a problem that the pieces become too hard and the pieces are difficult.

On the other hand, the molded clay brick 100 is preferably produced to be formed in a rectangular or square shape in order to improve the stability when the loading for carving and to facilitate reassembly.

The sculpture object forming step 30 is to form a sculpture object by stably building a molded clay brick 100 on a horizontal work plate according to the designed overall specifications of the clay sculpture.

Here, when forming the molding clay brick 100 to form the sculpture object, as shown in Figure 2 to form the molding clay bricks stacked vertically, or to cross to build the molding object.

The wet sculpture forming step 40 is to engrave the sculpture object in the form of circular or relief as shown in the design drawing, using the chisel molded clay brick 100 is cut out the entire contour of the embossed / written Expressed in detail using a carving knife, the surface finish can be completed by using a sculpture so that the surface of the molded clay brick 100 has a roughness.

On the other hand, the wet sculpture dismantling step 50 is to dismantle while writing the serial number on the molding clay brick 100 is carved from the top of the finished wet sculpture. The serial number may be an Arabic numeral such as 1, 2, 3 or any other identifiable number or symbol.

This serial number is for indicating the assembly position of the carved molding clay brick 100 when reassembled after dry firing.

In addition, according to the shape or size of the molded clay brick 100 when dismantling the molded clay brick 100 to prevent cracks during drying and firing of the molded clay brick sculpted as shown in FIG. It disassembles, forming one or more holes 101 or grooves.

On the other hand, the firing step 60 is the first step of preliminarily drying the molded clay brick dismantled in a sculpted state at a wind speed of 1 m / sec or less, a temperature of 10 to 30 ° C., and a relative humidity of 40 to 60% for at least 24 hours. A second drying step of drying the residual moisture of less than 3% for 24 to 40 hours in a drying chamber consisting of a drying step and a section in which the primary dried molding clay brick generates heat from room temperature to 120 ° C., and the 2 It consists of a firing step of firing the dried dried clay brick at a temperature of 900 ~ 1200 ℃ in the kiln.

If the wind speed in the primary drying step is 1m / sec or more rapid drying occurs cracks in the molded clay brick (100).

In addition, it is preferable that the room temperature is 10 to 30 ° C. in the first drying step. If the room temperature is 10 ° C. or less, cracks may be avoided in the molded clay brick 100, but the drying takes a long time and is 30 ° C. or more. The surface of the molded clay brick 100 is dried faster than the interior is cracked.

In addition, if the relative humidity of the room in the first drying step is less than 40% rapid drying occurs, cracks are generated in the molded clay brick (100), if the 60% or more takes a long drying time.

In addition, in the second drying step, the drying chamber is formed in a length of several tens of meters having a temperature gradient from the inlet to the outlet, and the molding clay 100 passes through the drying chamber from the inlet to the outlet for 24 to 40 hours, thereby drying. You lose.

This drying chamber consists of a section having a constant temperature from the inlet to the outlet. At this time, the first section is a section of room temperature and the temperature is increased by each section, the last section consists of a section having a temperature of 120 ℃.

When the drying is complete in the drying chamber like this, the molding clay brick 100 may be calcined in a kiln of 900 ~ 1200 ℃.

Maintaining the temperature of the kiln at 900-1200 ° C. has a problem that the strength of the molded clay brick 100 is not sufficiently sintered if the temperature of the kiln is less than 900 ° C., and the molded clay brick 100 is 1200 ° C. or more. It is preferable to configure the temperature of the kiln at 900-1200 ° C. because deformation may occur and final assembly may be impossible. 4 is a photograph showing a state of fired clay brick.

In addition, the atmosphere of baking can be an oxidizing salt, a reducing salt (flashing), and neutral.

In addition, the molded clay brick 100 has a firing can be coated with an inorganic compound on the surface in order to prevent surface contamination and to prevent copper damage. These inorganic compounds do not absorb water and can use conventional products that allow air to pass through.

Molded clay brick 100 is configured as described above is a ceramic material that emits a large amount of far infrared rays, it is environmentally friendly and beneficial to the human body. Therefore, when the clay sculptures are formed using these clay bricks, very environmentally friendly clay sculptures can be formed.

The reassembly step 70 is to confirm the serial number of the individual molded clay brick 100 is completed firing according to the drawing.

In addition, it is preferable that a clay foundation is constructed at a place such as concrete pouring and to form a constant gradient so that drainage can be made smoothly in rainy weather.

In addition, when the molding clay bricks (100) when the binder is laminated using an environmentally friendly inorganic adhesive.

On the other hand, the clay sculpture can be filled with ordinary clay brick or concrete, and if the clay sculpture has to be light, it can be filled with FRP (fiber glass reinforced plastic) or a steel structure.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims.
