The invention provides a reinforcing steel bar binding moulding bed frame for prefabricating T-beam wing plate and a use method in order to achieve the aim. The reinforcing steel bar binding mouldingbed frame comprises multiple connecting rods arranged in parallel, and two main stand rods are arranged at the two ends of each connecting rod and comprises a first main stand rod and a second main stand rod. The two ends of each connecting rod are welded to the corresponding first main stand rods, and main cross beams are welded to the top ends of the first main stand rods correspondingly. Multiple V-shaped brackets are welded between the main cross beams on the same side at equal intervals, and multiple corrugated pipe locating grooves are formed in the surfaces of the upper ends of the V-shaped brackets. The reinforcing steel bar binding moulding bed frame is simple in structure and convenient to manufacture, the work efficiency and work quality are improved, and waste caused in the construction process is effectively reduced; and the problems that T-beam wing plate binding consumes long time, T-beam pouring is influenced, and a corrugated pipe on the hogging moment portion of the T-beam wing plate is likely to shift are solved.
