The present invention relates to a safety diagnosis device for bridge deck expansion joint detection. The safety diagnosis device can significantly reduce measurement errors by maintaining a rod of a potentiometer without a change in length even when a bridge deck moves downwards, moves in the direction perpendicular to a throttle, or moves downwards in the direction perpendicular to the throttle at the same time and can prevent accidents such as bridge collapse in advance by estimating the service life and safety of a bridge by a result value and easily determining a maintenance point of time. |
