In the case where the front plate 110 and the back plate 130 are magnesium boards, the same is preferable. Accordingly, the first coating layer 112 of wood stain is formed on the front plate 110, and the second coating layer 132 of wood stain is formed on the back plate 130. As the front plate 110 and the back plate 130 used here, it is preferable to use a water-resistant plywood (S1).

Then place the front plate 110 and the back plate 130 to face each other and put the outer skeleton 150 along the edge of the two plates facing each other and fix it to the front plate 110 and back plate 130 . Preferably, the front plate 110 and the back plate 130 between the inner skeleton 152 and the heat insulating material 170 between the front plate 110 and the back plate 130 with a nail or screw on both sides before the fixing. It is fixed to the outer skeleton 150 and the inner skeleton 152, respectively (S2).

If there is no inner skeleton 152, the size of the heat insulating material 170 is to be the size of the front plate 110 or back plate 130 minus the width of the outer skeleton 150 of the edge portion, the inner skeleton 152 ), The inner skeleton 152 may be divided into the size of the space partitioned.

Then, preferably between the front plate 110 and the outer skeleton 150, and between the back plate 130 and the outer skeleton 150 by closely applying a bond for wood to eliminate the gap (S3).

Next, the cement filler is applied on the first coating layer 112 of the front wood stain of the front plate 110 to form an exposed concrete coating layer 114. Filler coating is applied to a thickness of about 1mm while directing pores using a resin bed (S4).

If you want to use a high-strength mortar as a filler, in the state in which the panel or the front panel 110 is being manufactured into the mold, pour the mortar thinly kneaded in water to spread the mold in a horizontal direction exposed concrete coating layer 114 to a predetermined thickness Can be formed. At this time, the thickness of the exposed concrete coating layer 114 is suitable 2 ~ 3mm but can be increased or decreased depending on the situation. In this case, the thickness of the exposed concrete coating layer 114 can be adjusted by adjusting the height of the frame protruding upward of the front plate 110. In this case, mass production of the exposed concrete panel 100 according to the present invention is possible. In some cases, the exposed concrete coating layer 114 may be formed by putting a small aggregate into the mortar. In this way, different shapes and textures can be obtained depending on the type, size and color of the aggregate. In this case, it is stable to make the exposed concrete coating layer 114 thicker than 3 mm.

After applying the cement filler or mortar to the front plate 110, it is dried, and after drying, the surface of the filler or mortar is polished with sand paper or the like (S5). As a result, the cement filler or mortar surface becomes slightly brighter.

The surface of the polished filler or mortar is soaked in a sponge and photographed (S6). At this time, the surface of the exposed concrete coating layer 114 is further exposed concrete texture while partially coating the surface of the filler or mortar polished by coloring the sponge. In some cases, this step can be omitted.

In addition, the convolut marks 111 are formed on the front plate 110. This may be formed by digging a cone bolt hole in the front plate 110 to a depth of 6 to 8 mm, and filling the cone bolt mark 111 to a thickness of 3 to 4 mm after appropriately stirring the remittal and cement. And an anchor bolt groove 134 is formed in the back plate 130. The position of the anchor bolt groove 134 is installed vertically when installing the exposed concrete panel 100 according to the present invention on the wall surface, or installed in a horizontally lying down state in one side of the upper and lower middle or at the left and right center of the top What is necessary is just to form (S7).

Then, the first resin coating layer 116 is formed by applying a silicone-based transparent resin to the surface of the front plate 110 (S8), and the second transparent resin coating layer 118 by applying a transparent fluorine resin thereon again To form (S9). The first resin coating layer 116 is to further enhance the waterproof performance, the second resin coating layer 118 is to prevent discoloration and to improve the waterproof performance. Silicone-based resins and fluorocarbon resins are coated with rollers or sprayers.

Here, steps S3 to S8 may be performed in advance before step S2, and it may be easily understood that the cone bolt marks 111 and the anchor bolt grooves 134 may also be changed in order according to the convenience of the work.
