The invention discloses a protective device for T-beam construction, which comprises a bracket assembly. The overall structural shape of the bracket assembly is I-shaped; two ends of the I-shaped topbeam are respectively provided with a pair of suspension roller assemblies; the two ends of the H-shaped bottom beam are each provided with a pair of supporting roller assemblies. Pedals are laid on the top faces of the I-shaped bottom beams, and riffled plates with anti-skid lines on the top faces are adopted as the pedals. The device can be stretched or contracted so as to meet the requirementsof different T-shaped beam distances. The hanging rollers and the supporting rollers can freely move in the length direction of the T-shaped beam, installation of diaphragm plate steel bars of the T-shaped beam of the whole bridge and hogging moment prestress construction are completed, the construction efficiency is greatly improved, labor and hoisting machines are reduced, the construction costis saved, and the construct
