The invention relates to a three-span antinode I-shaped beam-transverse wave-three-steel and concrete combined T-shaped continuous beam which comprises an antinode I-shaped beam (1) and a steel concrete combined top plate (2). A bridge span has a three-span continuous beam structure, and the setting of camber is not required. The invention firstly discloses an upper flange plate and a lower flange plate of the antinode I-shaped beam and are respectively parallel and level to a top plate and a bottom plate of the beam; the function of an antinode I-shaped beam reinforcing framework is fully utilized; temporary facilities used for pouring concrete on the top plate and the bottom plate are simplified; and concrete reinforcing bars are wrapped on the corrugated steel webs on the position of a supporting base along the length direction of a bridge and the thickness directions on the two sides, so that the maximum crushing stress of the lower edge of the section of the continuous beam supporting base is reduced, the buckling of the corrugated steel lower flange plate under the crushing stress is improved, and the diffusion of the concentrated force on the supporting base is benefited. The T-shaped continuous beam provided by the invention is high in construction speed and high in bearing capacity, requires no tensioning pre-stress, and is especially suitable for urban flyovers and engineering under strictly controlled under-bridge interference and tense working periods.
