Document Type and Number:
WIPO Patent Application WO/2007/097354
Kind Code:
A1
Abstract:
A PC steel stranded wire that has a strength greater than in the prior art, being
suitable for practical application; and a concrete structure utilizing the
same. The high-strength PC steel stranded wire that has a strength greater than
in the prior art, being suitable for practical application, can be manufactured
by fabricating of a 7-wire stranded structure through stranding of one center
wire together with six side wires and by regulating thereof so as to realize an
outside diameter of 15.0 to 16.1 mm, a total cross section area of 135 mm2
