Abstract
PURPOSE:To make the simple, quick and accurate measurement of the sizes of end holes possible by using a jig made by mounting a projecting body fitting to the end part of framework or the like to a bar rod, and attaching a scale starting from the centerline of the bar rod thereto. CONSTITUTION:A jig to be used is made by mounting a projecting body fitting by a socket and spigot fitting to the end hole of framework or the like to the circumferential part of a bar rod, and attaching a scale in a longitudinal direction with the position around the bar rod corresponding to the same position in the longitudinal direction of the bar rod of the centerline thereof as a start point. For example, a projecting part 8 mounted to a bar rod 7 attached with a scale 9 is fitted into the end hole 5 to be measured, and in this state the bar rod 7 is abutted to the framework side surface. If the scale 9 intersecting with a steel measure 10 placed along the bottom end surface of the framework 3 is read, the position of the end hole 5 is measured easily, quickly and accurately without requiring any particular skill.
