本発明は、深溝模様を有する硬質木片セメント
板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a hard wood cement board with a deep groove pattern.
セメントと木片フレークと水等とを混合し、こ
れを板状に成型固化させた硬質木片セメント板
が、建築用壁材料として多用されている。 BACKGROUND ART Hard wood cement boards, which are made by mixing cement, wood flakes, water, etc., and molding and solidifying the mixture into a board shape, are often used as wall materials for construction.
この硬質木片セメント板は、第１図に示すよう

の上下からプレス機３で加圧して常温で放置して
硬化させる。硬化後型板１を剥がせば模様のつい
た硬質木片セメント板ができ上る。 As shown in Fig. 1, this hard wood cement board is made by placing a mat-like material 2 made of a mixture of cement, wood flakes, water, etc. on a template 1 with a pattern formed on its upper surface, and then forming a set of these. A large number of sets are stacked together, and pressurized from above and below using a press machine 3, and left at room temperature to harden. After curing, the template 1 is peeled off to create a patterned hard wood cement board.
ところが、このような従来の方法によれば、型
板１の上にマツト状物２が積み重ねられた形で多
数組積層されるため、型板１が加圧により変形し
易く、その溝模様が型板１の裏面まで発生するこ
とから、残い溝の模様しか形成することができな
いという難点があつた。また、その積み重ねの数
にも限定があつた。 However, according to such a conventional method, many sets of pine-like materials 2 are stacked on top of the template 1, so the template 1 is easily deformed by pressure, and the groove pattern is distorted. Since the pattern extends to the back surface of the template 1, there is a problem in that only the remaining groove pattern can be formed. There was also a limit to the number of stacks.
また、比較的薄い合板、金属板などからなる型
板１を介在させた場合、型板１が極圧を受けると
損傷するおそれがあつた。 Further, when the template 1 made of relatively thin plywood, metal plate, etc. is interposed, there is a risk that the template 1 will be damaged if subjected to extreme pressure.
更に、通常のセメントを用いて木質セメント板
を製造すると10数時間から数日に渡る硬化時間を
必要とするという難点があつた。 Furthermore, manufacturing wood cement boards using ordinary cement has the disadvantage that it requires curing time ranging from several hours to several days.

80mm以上が好ましい。 In the present invention, the template 6 has a deep groove pattern 5 engraved on its upper surface, and is preferably made of a good thermal conductor. For example, a material made of an aluminum alloy such as Silumin, which is an alloy of aluminum and silicon, is suitable.
Further, the hot plate 8 is preferably made of a rigid metal such as iron. Its thickness is determined because the heat source 7 is installed inside and to prevent it from deforming under pressure.
80mm or more is preferable.

ズで仕上がりが良い。 In this way, when each set of the wood chip cement material 4 and the template 6 is heated by the hot plate 8, and when they are laminated and heated and pressurized, the temperature rise rate of each of the laminated wood chip cement materials 4 is fast; Consolidation dehydration significantly accelerates hardening. Furthermore, since the hot plate 8 is present, the template 6 is not deformed, and the pattern does not extend to the back surface, making it possible to manufacture a hard wood cement board with deep carvings. That is, even if extreme pressure is applied using the template 6 having the deep groove pattern 5, the temperature rises smoothly without damaging the template 6, resulting in a good finish.
