NONDESTRUCTIVE INSPECTION METHOD AND NONDESTRUCTIVE INSPECTION DEVICE OF ANCHOR BOLT

摘要

PROBLEM TO BE SOLVED: To provide a nondestructive inspection method and a nondestructive inspection device of an anchor bolt capable of quantitatively inspecting the soundness of an anchor bolt fixed to a foundation by an adhesion system anchor.SOLUTION: A nondestructive inspection method and a nondestructive inspection device of an anchor bolt for inspecting soundness of an anchor bolt fixed to a foundation by an adhesion system anchor is configured to generate a hammering sound by hammering a portion exposed from a surface of the foundation of an anchor bolt, acquires frequency information of a signal waveform by receiving the signal waveform and analyzing the frequency of the hammering sound, and inspects soundness of the anchor bolt in a nondestructive and quantitative manner based on the frequency information of the signal waveform.
