[Conventional technology]

Traditionally, steel products such as columns and beams used in building construction are manufactured individually in factories and then built. At the construction site, these single steel products are assembled by joining columns and beams to create buildings. . Steel products have holes in them to connect columns, beams, etc.

0003 For quality control of steel products, the total length of columns and beams, floor heights, joint lengths, etc. are measured between hole centers. Each part is measured as a reference. To measure the center-to-center distance of this hole, use the method shown in Figure 4. A score line 3 is formed at the center of the hole 2 formed in the H-shaped steel 1 as shown in the figure, and the length between the score lines 3 is It is conceivable to directly read and measure the height using a straight scale 6. However, such a ruler In the case where the wire 3 is used, if a rib 4 is welded between the holes 2, this rib 4 is in the way and it is impossible to directly measure between the scored lines 3, so there is an L-shaped difference between the scored lines 3. Measure the distance between the centers of the holes 2 by placing a pad 5 and a straightedge 6 between the pads 5. I try to do that.

0004

[Problem that the idea aims to solve]

When using the insert 5, measure while holding the insert 5. Therefore, it is not possible to accurately measure the distance between the score lines 3. and mark line 3 in each hole 2. It takes people and time. Also, the accuracy of score line 3 varies depending on the person, which is bad for the quality. influence
