(57) A reinforced concrete composite beam structure based on precast concrete beam-slab integrated units include rib beams and rebar cages; stirrups in the rib beams are closed stirrups; upper parts of the closed stirrups in each rib beam are extended from the rib beam and taken as connecting rings; the rebar cages are disposed on upper parts of two connected rib beams; the connecting rings are lapped with beam surface closed stirrups to form the reinforced concrete composite beam structure with the rib beams after casting concrete. Its construction method includes: installing the precast concrete beam-slab integrated units; hoisting the rebar cages on the rib beams to tie two corresponding connecting rings with the corresponding beam surface closed stirrup in a staggered and overlapped manner; and casting concrete to submerge the rebar cages. A form of the closed stirrups is proposed when rib width of the rib beams is small.
