Description of the Related Art Conventionally, building materials such as inorganic plate materials, which are molded from cement as a main raw material, have been very widespread. This inorganic plate material is basically nonflammable, and since the molding raw material is an inorganic material, it does not consume natural resources such as wood, can be molded into any shape, and can be used as a building material for various purposes. Have the advantage of. However, when these building materials have a simple flat plate shape, they are extremely poor in designability even though they function sufficiently as building materials, and therefore various surfaces are provided with uneven patterns to give a beautiful appearance. As the concavo-convex pattern, for example, a concavo-convex pattern such as a cross joint in brickwork may be added.

There is a problem in that it is technically difficult to attach uneven joints having a depth of approximately half the thickness to an inorganic plate material having a thickness of about this mm.

There is a method of cutting the surface of the shaped body with a router or a method of giving an uneven pattern to the surface of the uncured plate material with a press, etc., but for the first cast molding, the number of molds according to the manufacturing cycle is used. However, there is a problem in that the equipment cost is very high. Further, in the case of the second cutting, since the surface of the plate material once hardened is cut, there is a problem that the processing is very time-consuming and the productivity is low. The third pressing method has few problems such as the above-mentioned equipment cost and productivity, but it is almost impossible to press-form a deep deep groove due to material factors such as fluidity and plastic deformation of the material. There was a drawback that it was difficult to create a good and deep sharp uneven pattern.

The purpose of the method is to obtain a method for providing an uneven pattern on the surface of a plate material.

を特徴とするものである。[Means for Solving the Problems] That is, the method for imparting a concavo-convex pattern on the surface of a cement-based plate material of the present invention is to apply an irregular pattern at a depth of 1/3 to 1/2 of the thickness of the cement-based plate material. In the case of forming a plate-like body with a cement mixture having a water content of 40 to 45%, the shaped body surface is pressed at a pressure of 60 to 80 kg / cm 2 with a flat plate press to form a groove of the depth. It is characterized by applying pressure.

らである。In the present invention, the water content of the cement material is 40 to 45% with respect to the total solid content of the cement mixture. The reason for this is that if the water content is less than 40%, the fluidity in the cement formulation will be extremely low, and fine cracks will occur due to the press pressure, and the raw material will adhere to the mold, which will hinder smooth molding. And also 45%
If the amount is increased, the flowability of the material causes the material to escape due to the pressing pressure of the flat plate press, which hinders the linearity of the joint and causes the shape of the edge part to lose its shape. This is because it becomes difficult to form good unevenness.
