The invention relates to the technical field of bridge structure, in particular to a steel reinforced concrete beam rigid framework bridge. The bride comprises a pile foundation, bearing platforms grouted on the foundation, bridge piers supported by the bearing platforms and beam bodies supported by the bridge piers. The beam bodies comprise two concrete beams and steel box beams located between two concrete beams. Two concrete beams are fixed on the upper end of the bridge section, and are erected in the bridge sidespan section and partial midspan section along the positive direction of the bridge. The steel box beams are the steel beams erected in the midspan section along the bridge positive direction. Two ends of the steel box beams in the bridge positive direction are fixed to the ends of two concrete beams respectively. Reinforcing structures providing vertically upward forces to the box beams are arranged on the box beams. The steel reinforced concrete beam rigid framework bridge has the advantages is simple in structure. The spanning capability of the midspan section can be effectively elevated by the arrangement of the steel box beam structures. The negative effects brought by the concrete beam contraction and creeping can be relieved. The construction schedule is shortened. The steel reinforced concrete beam rigid framework bridge has a big promotion value.
