Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to provide a building board with a high design. [Structure] A large number of blocks (13) defined by joints (12) are arranged on the surface, and the inclination angle of the blocks (13) is variously changed to change the angle of light to various colors. Change the color tone.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a building board used as an interior material or an exterior material of a building.

[0002]

[Prior Art]

 Conventionally, for example, as shown in FIGS. 6 and 7, there has been provided a construction in which the surface of a building board (1) such as a fiber cement board is divided into a large number of blocks by joints (2). Then, for example, a horizontal striped pattern (3A) and a vertical striped pattern (3B) are attached to each block to give it a designing effect as a building board (1).

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional structure is merely a change in pattern and has poor design. However, changing the color tone of each block to further improve the design is extremely troublesome and not practical.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention arranges a large number of blocks (13, 23) defined by joints (12, 22) on the surface, and the block (13, 23) surface The present invention provides a building board (11, 21) having various inclination angles, and a building board (11, 21) coated with a gloss paint (14) on the surface thereof.

[0005]

[Action]

 In the building board (11, 21) of the present invention, since the surface inclination angle of the block (13, 23) defined by the joint (12, 22) is variously changed, the irradiation angle of the light L is different for each block (13, 23). 23) so that the color tone of each block (13,23) looks different.

[0006]

EXAMPLE The present invention will be described with reference to an example shown in FIGS. 1 and 2. The building board (11) is mainly a fiber cement board, a gypsum board, a magnesium carbonate board, a calcium silicate board or the like. And an inorganic plate, and a large number of blocks (13) defined by joints (12) are arranged on the surface. There are three types of the block (13): a block whose surface is inclined upward (13A), a block whose surface is horizontal (13B), and a block whose surface is inclined downward (13C). Luster paint (14) mixed with luster pigment such as mica powder is applied.

When the light L hits the building board (11) having the above-mentioned structure from diagonally above as shown in FIG. 2, the block (13A) on which the light L hits substantially vertically has the highest lightness, and then the light L slightly hits. The lightness decreases in the order of the block (13B) that obliquely strikes and the block (13C) that obliquely strikes the light L.

Therefore, even if the entire surface of the building board (11) of the present embodiment is coated with the same paint, the lightness and color tone is different depending on the inclination angle of the surface of each block (13).

3 to 5 show another embodiment of the present invention. In this embodiment, a large number of blocks (23A, 23B, 23C) defined by joints (22) are arranged in a circular pattern on the surface of the building board (21). As shown in FIG. 4, the surface of each block (23A, 23B, 23C) is inclined toward the center P, and the surface of the block (23D) is horizontal. Therefore, in this embodiment, the lightness and color tone of the circular pattern uniformly changes depending on the direction of the light. In this way, a building board with a high design having a pattern in which the brightness and color tone are partially changed by the pattern formed by the block and the inclination of the block can be obtained.

In order to manufacture the building board of the present invention, a predetermined concavo-convex pattern is formed on the mold surface, and the mold is filled with a material and pressed, or the material filled in the mold is solidified. Further, a method of pressing the surface with an embossing plate having a predetermined uneven pattern is used.

The block of the building board of the present invention may be arranged in a pattern having a predetermined shape other than the circular pattern, and the surface of the block may be provided with a pattern such as a fine concavo-convex pattern.

[0012]

[Effect of the device]

 Therefore, in the present invention, a building board having various lightness and color tone by each block and having an extremely rich design can be obtained.
