Where the position of B and the 0 scale of scale 5 are shifted,
It can be seen that the wall surface 1B or the juxtaposed pillars move in and out of the reference line, causing a construction error.

From the positional deviation between the vertical laser beam 4B and the 0 scale of the scale 5, it is determined whether the error of the wall surface 1B or the juxtaposed columns with respect to the installation reference line is protruding or concave. It can be understood, and by reading the deviation from the 0 scale, it is possible to measure how many cm error there is.

Further, in this embodiment, since the vertical laser light 4B is emitted from the black-out laser device 3, the measuring device A can be used within the irradiation range of the vertical laser light 4B. It is possible to check the positional relationship between the vertical laser beam 4B and the scale 5 at various places on the wall surface 1B or at various places on the juxtaposed columns,
Thereby, the detailed construction error of the wall surface 1B or the juxtaposed columns can be measured.

Then, based on the measurement results, necessary parts can be repaired.

Therefore, the horizontal error of the floor 1A and the error of the wall 1B or the column coming and going with respect to the installation reference line can be easily and accurately measured.
