Disclosed is a reinforcing steel support for colligation of a large-scale raft plate and ribbed beam base reinforcing steel. The reinforcing steel support can effectively reduce construction difficulty and cost. The reinforcing steel support comprises framework reinforcing steel (10) and hook reinforcing steel (20). The hook reinforcing steel (20) is arranged along the length direction of the reinforcing steel (10) in a spaced mode. The hook reinforcing steel (20) and the reinforcing steel (10) are welded into a whole. The space among the hook reinforcing steel (20) is the same as that of base horizontal reinforcing steel.
