A plurality of large, medium, and small-diameter grooves 141, 142, and 143 are dug as shown in FIG. 2 in this growing direction or in a state in which the cut log is vertically erected, and the transverse perforation 120 is used to cut the cut log. A plurality of large, medium, and small-diameter grooves (141, 142, 143) are dug out from the top to the bottom as shown in FIG. 5 in the horizontally lying state.

Here, the large-diameter groove 141 represents a rotary tool groove perforated to a standard of 25 mm to 40 mm or less using a woodworking drill, the medium-diameter groove 142 is a standard of 15 mm to 25 mm or less, and the small-diameter groove 143 is 15 mm The following specifications are shown.

The log 130 is longitudinally perforated 110 or transversely perforated 120 and a plurality of perforated grooves are formed in the perforated wood 140 in the longitudinal or transverse direction as shown in FIG. 2 or FIG. 5 . It is a step of drilling so that one side is closed by maintaining the end surface without penetrating the wood on the end surface that the woodworking drill touches in the process of doing this.

Hereinafter, reference numeral 200 denotes a perforated wood drying step, and after the wall surface is coated by injecting grain starch paste 320 into the large, medium, and small-diameter grooves 141, 142, 143 formed in the perforated wood 140, By drying in the shade, the cornstarch paste 320 is injected from the top downward in the state of FIG. 2 or 5, and the injection hole is directed downward so that the remaining cereal starch paste 320 is discharged in the downward direction. This is the drying step. Here, the grain starch paste 320 is made by diluting wheat flour or glutinous rice flour powder and water in a volume ratio of 1:4 and boiling it. It serves to prevent cracking and strengthen the bond with the injected liquid loess (330).

Reference numeral 300 denotes a liquid loess injection step, which separates sand particles larger than 1 mm and foreign substances contained in raw loess with a mesh network with dense holes like a net, and then pulverized powdered loess to a size of 0.125 mm or less. By injecting the liquid loess 330 in a thick form in which the grain starch paste 320 is mixed with wheat flour or glutinous rice flour grain powder in water into the inside of the perforation tree 140, the longitudinal perforation 110 is perforated The log 140 is injected from the upper direction as in the state of FIG. 3 , and the transversely perforated timber 140 in a state in which the cut log is lying horizontally is injected from the upper direction as in the state of FIG. 5 . .

The liquid loess 330 is mixed with the volume ratio of the powdered loess 310 and the grain starch paste 320 at 9:1, and water is added to 15-20% of the total volume and stirred in a thick state. Large, medium, and small-diameter grooves (141, 142, 143) in the interior of the injectable concentration is diluted.

When injecting the liquid loess 330 into the large, medium, and small-diameter grooves 141, 142, 143, inject it using a funnel, and apply vibration to the body of the perforated wood 140 with a vibreda or a striking tool. 330) and the large, medium, and small-diameter grooves (141, 142, 143) by discharging the air to strengthen the cohesive force. After the moisture is absorbed into the body of the perforated wood 140 and dried, when the volume of the liquid loess 330 decreases and the upper end subsides, the liquid loess 330 is additionally injected from time to time, as shown in FIG. 3 or FIG. 6 . It is a step of injecting to coincide with the upper surface of (140).

Reference numeral 400 denotes a drying step of loess injection wood, where liquid loess 330 is injected into the longitudinal perforation 110 or transverse perforation 120 perforated wood 140 to fix the inlet in the upward direction. In the drying step, in the process of drying the liquid loess 330, the wall surfaces of the large, medium, and small-diameter grooves 141, 142, 143 and the solid loess injection wood 410 are formed as a single body, wherein the loess In the process of sawing the injection wood 410, the hardened loess 340 is dried in the shade for at least 20 days to prevent cracking due to a decrease in strength due to the moisture content, so that the hardened loess 340 is flattened by the saw blade. This is the drying step.

Reference numeral 500 denotes a loess-injected wood sawing step, in the method of sawing the dried loess-injected wood 410 by drilling (110, 120) in the longitudinal or transverse direction and injecting the liquid loess 330 in the longitudinal direction. Lumber 510 is a longitudinally perforated 110, liquid loess loess 330 is injected into the inside of the perforated wood 140, and the dried loess-injected wood 410 is laid horizontally in the longitudinal direction to produce loess wood boards. (530) is to be obtained, and the transverse material 520 is a state in which the liquid loess 330 is injected into the transverse perforation 120 and the perforated wood 140 and the dried loess injection wood 410 is laid horizontally. It is a step of obtaining a loess wood board 530 by sawing in the transverse direction.

At this time, when the thickness of the loess wood board 530 to be sanctioned is thin, the thickness of the plate sanctioned in the longitudinal direction is at least 10 mm to prevent the hardened loess 340 from being separated from the wood plate in the process of moving or installing the plate. It is desirable that the thickness of the plate to be sawn in the transverse direction is at least 20mm or more.

Reference numeral 600 denotes the completion stage of the ocher wood board, the surface of the loess wood board 530 subjected to the longitudinal saw 510 as shown in FIG. This is the step of smoothing the wood board and the loess layer so that it is flat by using a sander equipped with sandpaper.

The manufacturing method according to the procedure diagram will be described in detail with reference to the drawings of FIGS. 2 to 7 .

2 is a view showing a number of large, medium, and small-diameter grooves 141, 142, and 143 by erecting the body of the log 130 cut to a certain standard in the direction of growth and drilling from top to bottom with a woodworking drill. A perspective view showing the formed state and a cross-sectional view taken along the line a-a', which shows the perforated wood 140 with the perforation 110 in the longitudinal direction, and FIG. It is a perspective view showing a state in which a plurality of large, medium, and small-diameter grooves 141, 142, 143 are irregularly formed by drilling from the top to the bottom, and a cross-sectional view taken along the line a-a'. ) shows the perforated tree 140 .
