Title:
DEVICE FOR DETECTING FRACTURE OF REBAR FOR UTILITY POLE
Document Type and Number:
WIPO Patent Application WO/2017/043753
Kind Code:
A1
Abstract:
The present invention relates to a device for detecting fracture of a rebar for a utility pole, comprising: a detection unit (10), which is in close contact along the circumferential outer surface of the utility pole, for detecting magnetic fields generated from a plurality of rebars (3), which are buried in a utility pole (1), in positions corresponding to the rebars (3); a data logger unit (20) for receiving magnetic field data regarding the rebars (3) detected by the detection unit (10) and storing the same; and a fracture status detection unit (30) for detecting the fracture status of the rebars (3) on the basis of the amount of change in magnetic field included in the magnetic field data stored in the data logger unit (20). The present invention is advantageous in that it is possible to detect the fracture status of a plurality of rebars simultaneously, and that it is also possible to easily detect the fracture status of rebars of various utility poles with different diameters.
