THE VERTICALITY MEASUREMENT DEVICE OF STEEL ERECTION USING LASER SENSING TECHNOLOGY

摘要

A verticality measuring device of a steel erection by laser sensing technology is provided to help unskilled users to carry out the measuring work precisely and safely by using laser beams, thereby simplifying the mounting and handling thereof. An erection attaching frame(110) is able to be attached to a steel erection by using magnets and has a hole(150) for projecting laser beams. A weight is connected to a laser beam projection unit with a freedom degree in every direction in the frame and stopped moving in a short time by own weight for making laser beam projection possible. The laser beam projection unit(130) projects the laser beams in the vertical direction. A power supply(140) supplies power to the laser projecting unit.
