Document Type and Number:

WIPO Patent Application WO/1997/032084

Kind Code:

A1

Abstract:

A method of repairing and reinforcing a prestressed concrete structure which is given prestress by tension members such as PC steel member. Reinforcement sheets (16) are secured to ends of tension members (7) provided in a structure (1) or to surfaces of coverings for the ends to repair them whereby the ends of the tension members are covered with reinforcement materials. With such arrangement, even when the tension members are broken, the ends of the dislocated tension members are blocked by the reinforcement sheets to prevent the tension members from projecting outside the structure.
