Claims

[Scope of utility model registration request]

A handle is provided at approximately the center of the surface, and a right-angled corner is provided, and a substantially planar locking edge is provided vertically at a right angle at a side end connected to the right-angled corner,
A reference hole is drilled at a predetermined position inside the right-angled corner as one of the corners of the virtual square serving as the center point, and holes are drilled at positions corresponding to the other three corners, and further holes are drilled at positions corresponding to the other three corners. The upper end of the punch is protruded and the tip is inserted into the reference hole of the substrate, which is formed by making the reference hole one of the corners of the second imaginary square and drilling holes at positions corresponding to the other three corners. A plate for a steel frame column, characterized in that a loaded cylinder is housed and biased upward so that it can be raised and lowered, while cylinders loaded with punches are detachably attached to the other three holes. Centering jig.
