<p>PURPOSE:To provide a shape measuring device of a shape steel capable of accurately measuring the shape and size of a shape steel without being affected by the tilt of a flange and the curvature of a web. CONSTITUTION:U-shaped support frames 24R, 24L are arranged to individually cover the right and left halves of a rolled material such as an H-shape steel movably in the right and left directions, and a two-dimensional laser range finder 31 radiating a slit laser beam to the flange outer face in the width direction to measure the distance is arranged at the center section of the vertical lever section 27 of the support frames 24R, 24L. Two-dimensional laser range finders 32U, 32L radiating the slit laser beams to the flange upper and lower faces, flange inner face, and web upper and lower faces at the prescribed angles in the direction perpendicular to the conveying direction to measure the distances are arranged on the end faces of horizontal lever sections 28U, 28L. The distance data detected by the laser range finders are arithmetically processed by an arithmetic processor, the cross sectional shape data of the rolled material are obtained, and the size data of the prescribed measurement items are calculated from the cross sectional shape data.</p> |
