摘要
The purpose of the present invention is to provide a nondestructive inspection method and nondestructive inspection device for an anchor bolt capable of quantitatively inspecting the health of an anchor bolt fixed to a foundation by a metallic anchor. Provided is a nondestructive anchor-bolt inspection method for inspecting the health of an anchor bolt fixed to a foundation by a metallic anchor, wherein a striking sound is produced through the striking of a portion of the anchor bolt exposed from the surface of the foundation, frequency information is obtained through the reception and frequency analysis of the signal waveform of the striking sound, and the health of the anchor bolt is nondestructively and quantitatively inspected on the basis of the frequency information for the signal waveform. Also provided is a nondestructive inspection device for an anchor bolt.
