<P>PROBLEM TO BE SOLVED: To provide a method of working matching surfaces of steel structures by which the dimensional accuracy (height, inclination) of matching surfaces of steel structures is exactly calculated in a short period of time without requiring time and labor when the matching surfaces of the steel structures are worked at site in the construction of steel structure equipment by assembling the steel structures for decrepitude update. <P>SOLUTION: A plurality of measurement points are set on each matching surface, three-dimensional coordinate positions of the plurality of the measurement points are measured by using a three-dimensional laser-beam measuring apparatus for obtaining the three-dimensional coordinate positions of the measurement points, virtual reference surface is made based on the obtained three-dimensional coordinate position data of the whole measurement points, a specific matching surface is used as a reference and the dimensional accuracy (height, inclination) of the residual matching surfaces with respect to the virtual reference surface is calculated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
