Title:
STEEL FOR UNBONDED PRESTRESSED CONCRETE, ITS MANUFACTURING METHOD AND STRUCTURE
Document Type and Number:
Japanese Patent JP2007040052
Kind Code:
A
Abstract:
To provide unbonded steel for prestressed concrete additionally having a simple antiseismic damping function, and an unbonded prestressed concrete structure using the unbonded steel for prestressed concrete.
Steel 2 for prestressed concrete is placed in a sheath 1. A viscous antirust 4 is filled in a gap 3 between the sheath 1 and the steel 2 for the prestressed concrete. A winding sheath, polyethylene sheath or the like having a high adhesion is used for the sheath 1. PC steel rods, PC stranded wires, or deformed PC steel rods, high-strength steel bars or the like are used for the steel 2 for the prestressed concrete. The antirust 4 having a viscosity is also used.
