The present invention relates to a measuring device for air content in concrete. A support rib is provided on a circumference of a coupling boss and has a tapped hole, and a coupling rib is provided on the circumference of an upper cover and has penetrating holes. In addition, a coupling bolt passes through the penetrating holes of the coupling rib and is coupled onto the tapped hole of the support rib so as to attach or detach the upper cover onto or from the coupling boss. Therefore, it is possible to attach or detach the upper cover onto or from the coupling boss with easy through a simple operation of fastening or loosening the coupling bolt, thereby being easy to clean air chamber in the coupling boss periodically. A transporting part of the present invention is used for transporting a measuring device for air content in concrete and protects a pressure gauge which is easy to be damaged by being exposed out to external shock by protruding upwardly, thereby preventing the pressure gauge from damage. 본 발명은 콘크리트 공기량 측정장치에 관한 것으로, 결합보스의 둘레에 나사구멍이 형성된 지지리브가 형성되어 있고, 상부커버의 둘레에는 관통구멍이 형성된 결합리브가 형성되어 있으며, 체결볼트가 결합리브의 관통구멍을 통과한 후 지지리브의 나사구멍에 체결되어서 상부커버를 결합보스에 착탈시키도록 구비된다. 따라서, 체결볼트를 풀거나 조이는 매우 간편한 작업으로 상부커버를 결합보스에 간편하게 착탈시킬 수 있으며, 이에 따라 결합보스 내부의 공기실을 정기적으로 청소하기가 용이하다. 또한, 본 발명의 운반부는 콘크리트 공기량 측정장치를 운반하는데 사용될 뿐 아니라, 상측으로 돌출되어서 외부의 충격에 그대로 노출되고 충격에 매우 취약한 압력계를 보호하므로 압력계의 파손을 방지시킨다.
