Reinforcement cage suspension device

A steel reinforcement cage suspension device is characterized in that unit suspensions are formed by full-length main steel bars, hinges, transverse rods, vertical steel bars and hooks, and at least two unit suspensions, ground sleepers and load-carrying steel beams are combined to form the steel reinforcement cage suspension device. And all the sections with the same length of the full-length main reinforcing steel bar can be rotatably folded relative to the other section through the hinges. The lengths and the distances of the cross rods between the first section of reinforcing steel bar and the vertical reinforcing steel bar are equal, the cross rods are welded with the first section of reinforcing steel bar and the vertical reinforcing steel bar at 90 degrees, a plurality of rectangular grids are formed between the adjacent cross rods, and the reinforcing cage is suspended on the load-carrying steel beam for positioning elevation through the cross rods of the rectangular grids at different positions of th
