The two groups of movable columns 7 are symmetrically arranged with the exposed steel bar 2 as the central axis. The movable column 7 and the protective tube 3 are vertically installed. The movable column 7 is movably connected to the protective tube 3. A locking strip 9 is arranged at one end of the movable column 7 close to the exposed steel bar 2. The locking strip 9 is an arc strip. The inner arc edge of the locking strip 9 is adapted to the outer surface of the exposed steel bar 2. One end of the locking strip 9 is fixedly connected to the movable column 7. A rotating ball 8 is arranged at one end of the movable column 7 close to the inner wall of the rotating seat 6. The rotating ball 8 is movably installed inside the movable column 7. The end of the rotating ball 8 away from the movable column 7 contacts with the inner wall of the rotating seat 6.

[0024] Embodiment 3: A device support for preventing exposed reinforcement bars in concrete forming, based on Embodiment 2 Figure 1-Figure 3As shown, the moisture-proof component 5 includes a storage tube 14, which is a cylindrical hollow tube.
