  • Process and apparatus for measuring sizes of steel sections
    Patent number: 5253039
    Abstract: In the size measurement of steel sections, a pair of two-dimensional rangefinders and a pair of one-dimensional rangefinders are arranged so as to sandwich a steel section consisting of a pair of flange portions and a web portion in a widthwise direction of the flange portion and face to each other, whereby a vertical distance ranging from the two-dimensional rangefinder to the flange portion and a vertical distance ranging from the one-dimensional rangefinder to the web portion are measured, respectively to calculate a deviation at center, a flange width and a web thickness from the above measured values. In this case, a laser rangefinder is used as each of the two-dimensional rangefinder and one-dimensional rangefinder.
