INSTALLATION ERROR MEASURING INSTRUMENT FOR BUILDING, LEVELING ERROR MEASURING METHOD FOR FLOOR FACE, AND ALIGNMENT ERROR MEASURING METHOD FOR WALL SURFACE OR JUXTAPOSED PILLAR

摘要

PROBLEM TO BE SOLVED: To provide an installation error measuring instrument for a building, a leveling error measuring method for a floor face, and an alignment error measuring method for wall surfaces or juxtaposed pillars, capable of measuring the existence of a leveling error in a floor face and an aligning error in a wall surface or in juxtaposed pillars relative to a reference line for installation. ;SOLUTION: In this installing error measuring instrument for a building, a scale-attached body 6 with a scale 5 attached thereto is slidably mounted on a substrate 2 abutting on a reference plane 1, such as the floor face 1A, the wall surface 1B, or a side face of a pillar. The scale 5 is brought in line with a laser beam 4 emitted from a laser device 3 for marking. A fixing mechanism 7 for fixing the body 6 in a non-slidable manner to the substrate 2 is provided so as to extend from the body 6 to the substrate 2.;COPYRIGHT: (C)2001,JPO
