Abstract
PURPOSE: To measure a gap between ultrasonic transmitting and receiving methods provided apart on a metal plate, by measuring a received wave by transmitting an ultrasonic wave toward a concrete sode when casting concrete adjoining to the metal plate.
CONSTITUTION: There is concrete 3 adjoining to steel plate 20. On steel plate 20, ultrasonic sender 11 and ultrasonic receiver 12 are provided at an interval of fixed distance, sender 11 sends a wave of a fixed frequency through pulse oscillator 13, and a voltage of a received ultrasonic wave displayed on synchroscope 16 through pre-amplifier 14 and dicriminator 15 is masured to measure a gap. As the received voltage is lower, the packing density of concrete is higher, so that the degree of the gap can quantitatively be measured without destroying.
