Prestressed concrete roof structure system applied to elevated station

A prestressed concrete roof structure system applied to an elevated station is used for effectively improving the durability of a roof structure of the elevated station, reducing the self weight of the roof structure and increasing the use span of the roof structure. Comprising reinforced concrete stand columns, prestressed concrete beams, roof structure edge beams, roof middle longitudinal beams and reinforced concrete roof panels. The reinforced concrete stand columns are longitudinally arranged on the two transverse sides of the station platform layer at intervals. The prestressed concrete beams are longitudinally arranged at intervals and stretch across the whole platform layer, and the two ends of each prestressed concrete beam are fixedly connected with the tops of the reinforced concrete stand columns on the same side. The roof structure edge beams extend longitudinally, are arranged on the tops of the reinforced concrete stand columns on the same side and are fixedly connected with the reinforced conc
