THE MEASURING DEVICE TO CROSS-SECTIONAL SHAPE AND DISPLACEMENT CONVERGENCE OF STRUCTURE

摘要

Disclosed is a device for measuring a cross sectional shape and a displacement convergence of a structure using a laser beam for safety inspection, construction and maintenance of the structure. The device for measuring the cross sectional shape and the displacement convergence of the structure using the laser beam for safety inspection, construction and maintenance of the structure comprises a base; a support installed on the base to be vertical to the base; a rotary measuring unit installed in the support to be rotatable and emitting and receiving the laser beam to measure the cross sectional shape and the displacement convergence of the structure; and a brake device installed between the support and the rotary measuring unit to fixate the rotationtal angle of the rotary measuring unit, wherein the rotary measuring unit is connected to the support via a rotational shaft, the longitudinal direction of the rotational shaft is vertical to one side vertical to an upper side of the base, and the rotary measuring unit coupled to the rotational shaft is configured to rotate in the circumferential direction of the rotational shaft around the rotational shaft.
