PC COMPOSITE STRUCTURE, PC BRIDGE AND PRESTRESSING METHOD

摘要

PROBLEM TO BE SOLVED: To increase the structural strength of a PC (prestressed concrete) composite structure by preventing separation at an interface between the steel skeleton and the concrete structure part of the PC composite structure. SOLUTION: The PC composite structure includes a steel reinforced concrete composite body where a steel structure part 20 and a reinforced concrete structure part 30 are integrally joined together; a PC steel member 40 used to apply compressive force to the steel reinforced concrete composite body to prestress the composite body; and a bearing plate 50 positioned between the PC steel member 40 and the composite body at the prestressed portion to abut both the steel structure part 20 and the reinforced concrete structure part 30 of the composite body to transmit the compressive force of the steel member 40 to both the steel structure part 20 and the reinforced concrete structure part 30.
