Abstract:
This invention provides a method and device for nondestructive testing of an anchor bolt. Said method and device make it possible to quantitatively test the soundness of an anchor bolt affixed to a foundation via an adhesive anchor. In this method for nondestructive testing of an anchor bolt, in which the soundness of an anchor bolt affixed to a foundation via an adhesive anchor is tested, a section of the anchor bolt that is exposed from the surface of the foundation is hit so as to produce an impact noise, a signal waveform corresponding to said impact noise is received and subjected to frequency analysis so as to obtain frequency information for said signal waveform, and the soundness of the anchor bolt is nondestructively, quantitatively tested on the basis of said frequency information.
