Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building board material.

[0002]

2. Description of the Related Art Fiber reinforced cement boards are very widely used as building boards. These construction board materials are appropriately cut and used according to the size of the target wall surface at the construction site. This cutting line is drawn with a ruler etc. and cut along with it with a saw, etc., but to draw the drawing line at a right angle or parallel to the edge of the building board material, scale on one side of the board material It is necessary to measure each point at a constant distance by using, for example, and it is troublesome to repeat such work each time.

[0003]

[Problems of the prior art] Further, in the case of a fiber reinforced cement board having an uneven surface pattern, if the surface is cut with a saw, it is difficult to cut straightly due to the unevenness, and the surface pattern may be soiled. The plate is placed face down, a scribe line is placed on the back, and a saw is applied to cut it. Therefore, even when the scale line is inserted on the scale, it is necessary to repeat the plate material each time and the work becomes more troublesome.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention makes it possible to easily and accurately insert a ruled line when a plate material is cut at a construction site without using a scale or the like. The purpose of the invention is to provide a building board material that can be used.

[0005]

That is, the building board material according to claim 1 is characterized in that a dimensional scale 3 is printed on a back surface edge 2 of a plate-shaped main body 1, In the building board material according to claim 2, a dimensional scale 3 starting from a longitudinal end portion of the main body 1 is provided on both end edges 2 of the back surface of the main body 1 in a plate-like shape, and the graduated scale starting ends are opposite to each other. The building board material according to claim 3 is characterized in that it is attached to the back surface of the main body 1 in the form of a plate, and parallel lines 3A and 3B that are parallel to and perpendicular to the main body edge 2. Is printed at regular intervals.

[0006]

In the first aspect, the dimensional scale provided on the back surface of the main body serves as a reference scale for cutting the plate material. Therefore, the desired size can be easily calculated without using a scale or the like. Further, in the dimensional scale according to the second aspect, since the graduation start end has an inverse relationship between the one end and the other end of the plate material, either scale can be used for cutting the plate material. In addition to the above, the parallel lines in claim 3 remain on the back surface of the plate material even if any or all of the periphery of the plate material is cut off. Therefore, it is easy to accurately determine the dimensions even for a plate material having four processed sides.

[0007]

Next, an embodiment of the present invention will be described. 1 is a rear view of an embodiment of the invention according to claim 1, and FIG.
It is a back view of the Example of the invention which concerns.

[Embodiment 1] As shown in FIG. 1, the short side is 455 m.
m Fiber-reinforced cement board with a long side of 2880 mm 1 Long side of the back surface 2,
The dimensional scales 3 and 3 as shown in a partially enlarged view of FIG. 2 were printed by a printing device at the factory production stage. [Example 2] As shown in Fig. 2, the 0 position of the dimensional scale 3 along the long sides 2 and 2 on the back surface of the same fiber reinforced cement board 1 as in Example 1 was printed in an inverse relationship. [Example 3] A line 3A perpendicular to the long sides 2 and 2 and a line 3B parallel to the long sides 2 and 2 are printed on the entire surface of the back surface of the fiber-reinforced cement plate 1 having a short side of 455 mm and a long side of 2880 mm at intervals of 5 cm, and the length and width are A graduation 3 in 1 cm increments was printed on the center line.

When the building board 1 of Examples 1 and 2 is cut to a required length at a construction site, in the case of Example 1, it is easy to draw a line by directly connecting scales having the same size. I was able to draw a writing line. Example 2
In the case of No. 2, it was possible to draw a ruled line for cutting the plate material 1 to a desired length by using the scale 3 which is convenient for use when the plate material 1 is placed. In the case of Example 3, by selecting one of the graph-shaped lines, it was possible to directly cut without writing a scroll line.

Further, with respect to the remaining pieces after cutting, it was possible to make a cutting piece having a continuous surface pattern by utilizing vertical and horizontal scale lines. When drawing a line with the required gradient, the scale line could be easily obtained using the scale 3. In addition, in the case of Example 3, the scale of 1: integer was easily obtained by using a graph-shaped scale line.

[0011]

According to the construction board material of the first aspect, it is possible to easily cut it to a required length without using a scale. Especially in the case of a building board with an uneven pattern such as brickwork on the surface, it is possible to cut while maintaining the continuity or periodicity of the surface pattern by referring to the dimensional scale, which makes it extremely convenient for on-site construction. Has the effect of facilitating. According to the building board material of claim 2, when cutting the building board material to the required length from the end, any one of the dimensional scales may be used, so the attitude of the board material is changed for measurement. It has the effect of not having to. Also,
According to the building board according to claim 3, in addition to the above-mentioned effect, even if the board is cut off at its periphery, the board can be trimmed in the correct posture by using the scale line, and the building board is not wasted. It has the effect that it can be used. In addition, the oblique line of the required gradient can be easily obtained by using a grid-like scale line.
