Abstract

PURPOSE: To easily measure the dimension and obtain measuring results correctly and surely, by placing a rectangular green sheet having a plurality of groove parts on the surface thereof in the longitudinal direction on a flat surface and measuring the size between inner walls of two grooves closest to both ends in the width direction of the sheet. CONSTITUTION: The rectangular green sheet 3 has a plurality of groove parts 1 on the surface thereof in the longitudinal direction. The green sheet 3 is placed on a flat surface. The size of inner walls of one groove part 1 and the other groove part 1 closest to both ends of the green sheet 3 in the width direction is measured. For instance, the green sheet 3 is formed out of water- base slurry mainly composed of cement, an aggregate and a reinforcing material, consisting of, e.g. approximately 60-70% of solid and 30-40% of water and having so-called joints. Accordingly, a measuring position is on a line connecting points, without dispersion in measured values due to measuring people. Even a soft green sheet of a large width can be measured easily.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a green sheet size measuring method and a measuring device therefor, and more particularly to a green sheet size measuring method and a measuring device useful for building boards and the like. .

[0002]

2. Description of the Related Art As a conventional green sheet dimension measuring method, for example, a measuring instrument such as a convex scale or a caliper is used, and such a measuring instrument is used for a building board or the like. It is a useful rectangular shape and has a plurality of grooves along the longitudinal direction on its surface, and the width of the green sheet is measured by directly applying the dimension of the soft, scratch-prone green sheet to the green sheet. It was something that

[0003]

However, in such a green sheet dimension measuring method, even if the width dimension is measured, both end portions in the width direction are subjected to cutting work at the time of construction or the like. The width dimension did not make sense. Further, when the convex scale was used, the measurement accuracy was poor because the minimum scale was 0.5 mm. On the other hand, in the case of using calipers, if the width dimension is large and soft like a green sheet, the claws of the caliper may bite into the side walls at both end portions in the width direction and damage the green sheet. As a result, it was difficult to measure by myself.

Therefore, it has been considered to measure the width of the green sheet at intervals between the groove portions that are closest to both ends in the width direction, but when the convex scale is used, the minimum scale is 0.5 mm. As a result, the measurement accuracy remains poor. On the other hand, even when using calipers, the width dimension is large like the green sheet as described above, and if it is soft, the calipers claws damage the surface of the green sheet, and still,
It was difficult for one person to measure.

In any case, it is difficult to measure the dimensions, and there is a large variation among measuring persons.

The present invention has been made in view of the above facts, and an object of the present invention is to make it possible to easily perform dimension measurement and to accurately and surely measure the dimension. It is an object of the present invention to provide a green sheet dimension measuring method and a measuring apparatus therefor.
