PURPOSE:To raise practicability by calculating a state in a corner part of a room as a moving extent for correcting the corner part to a right angle. CONSTITUTION:A table is prepared by an equation. First of all, one corner part of a room is set as a reference point or start point O, and a mark point A is put onto a parquet part being in one side edge of the room, which is at a specified distance by the table from the start point O. Subsequently, a gauge-rod whose length is seven feet is used, its one end is pressed against the part onto which the mark A is put, and also the other end is brought into contact with the second parquet part existing in the other side edge of the room and is rubbed up and down lightly, by which a mark B is put onto the second parquet part. Subsequently, the distance between this mark part and the start point O is measured, is collated with the table, and its corrected value is derived. Subsequently, by adding its corrected value, mat dimensioning can be executed. |
