Supporting device of concrete reinforcement cage

The utility model discloses a supporting device of a concrete reinforcement cage, which comprises a supporting frame arranged in the concrete reinforcement cage, the supporting frame comprises a supporting rod, a plurality of vertical rods and a plurality of lock catch mechanisms, the supporting rod is used for supporting an upper reinforcing mesh, the plurality of vertical rods are sequentially arranged at intervals along the horizontal direction, and the lock catch mechanisms are arranged on the vertical rods. The lock catch mechanisms are used for fixedly connecting the vertical rods and the supporting rods correspondingly, and the vertical rods and the supporting rods are matched to form a supporting structure used for enabling an upper-layer reinforcing mesh and a lower-layer reinforcing mesh of the concrete reinforcement framework to be arranged at intervals in the vertical direction. According to the supporting device for the concrete reinforcement framework, through cooperation of the multiple vertica
