Steel-concrete plate truss combined bridge deck structure

The invention belongs to the technical field of steel truss girders, and particularly relates to a steel-concrete plate truss combined bridge deck structure. Comprising a main truss lower chord and a steel-concrete combined bridge deck structure, wherein the main truss lower chord comprises a side truss lower chord and a middle truss lower chord; the steel-concrete combined bridge deck structure comprises an integral steel plate, PBL shear keys, longitudinal perforated steel bars, common longitudinal steel bars, common transverse steel bars and cast-in-place concrete. The integral steel plates are lapped between every two middle girder lower chords or between the middle girder lower chords and the side girder lower chords; the PBL shear keys are welded on the top surface of the integral steel plate; the longitudinal perforated steel bars penetrate through the circular holes of the PBL shear keys to be overlapped on the PBL shear keys; the common longitudinal steel bars are lapped on the top surfaces of the PB
