Abstract

PURPOSE: To measure up-down extent of curvature without rotating a steel material by supporting the steel material by a couple of balance type supporting devices and by measuring slanting angles of those devices.
CONSTITUTION: Steel material 1 is supported by balance type supporting devices (a), (a). A load should be applied to external fulcrum A and internal fulcrum B equally. Consequently, slanting angles (α) of balance type supporting devices (a), (a) are obtained and from L a half the length of steel material 1, Lsinα, up-down extent of curvature is obtained. Thus, the up-down curvature extent can be measured accurately without rotating the steel material.
