Reinforced concrete crack measuring device

The utility model discloses a reinforced concrete crack measuring device for measure the internal fissure of wall body, include that high -decibel buzzer, noise meter, vacuum seal sound production cover, vacuum seal monitor the cover, the high -decibel buzzer is connected with A type vacuum tube, a type vacuum tube switches on with vacuum seal sound production cover, vacuum seal sound production cover bottom is fixed on one side of the wall body, the noise meter is connected with the type B vacuum tube, the type B vacuum tube switches on with vacuum seal monitoring cover, vacuum seal monitoring cover bottom is fixed with the wall body opposite side. The singing that adopts certain decibel of high -decibel buzzer production once utilizes the vacuum seal monitoring to cover through the wall body and collects the singing after vacuum seal sound production cover sends, measures the singing decibel through the noise meter, measures for regional decibel with the undamaged structure of reinforced concrete to reach the crack circumstances of measuring reinforced concrete, but also the multiple metering is monitored to fissured development.
