description The invention discloses a steel-concrete composite beam panel and UHPC bottom die integrated structure and a construction method, and relates to the field of bridge energy-saving construction.The integrated structure is mainly characterized in that a plurality of U-shaped steel beams are installed on a support of a bridge pier and abutment, and a steel top plate with a certain width and the same length as the U-shaped steel beam is welded to the top of each of the two sides of each U-shaped steel beam; a plurality of shear keys are welded to each steel top plate, then UHPC bottom dies are installed on the top of each U-shaped steel beam and between the steel top plates of every two adjacent U-shaped steel beams, bridge floor steel bars are installed on the UHPC bottom dies, concrete is poured on the UHPC bottom dies to form a reinforced concrete bridge floor, and an asphalt surface layer is laid on the reinforced concrete bridge floor. The integrated structure has the advantages of being simple in structure,
