The soundness of the adhesive system anchor bolt used for fixing signboards and tunnel ceiling plates was evaluated by ultrasonic wave. The adhesion state of the anchor bolt was examined from the amplitude ratio B / A of the reflected signal A from the tip of the anchor bolt and the signal B generated late. The value of B / A decreased when the concrete pilot hole where the anchor bolt adhesion state deteriorates is too large, or the pilot hole is insufficiently cleaned. Also, ultrasonic wave propagation inside the anchor bolt was confirmed by simulation, and it was confirmed that the signal B generated late was a signal reflected from the thread near the tip of the anchor bolt. |
