Abstract
Abstract This invention generally involves wire rope which is suitable for use in the concrete working in very tall buildings or ultra high buildings. More particularly, this invention relates to a wire rope which has an extremely coarse-laid surface so as to increase adhesive strength or bond strength in respect to the placed concrete.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
An extra coarse-laid wire rope for reinforced concrete building construction, comprising: a plurality of strands, each incorporating a plurality of wires laid helically in the same angular sense to provide a built-up lay; at least two strands, each incorporating a plurality of wires, said at least two strands each being of at least as great diameter as the first-mentioned strands and being helically wound in two angularly opposite senses upon said built-up lay so as to cross one another at a phase angle of about 180* ; the at least two strands being spaced to expose said lay exteriorly of the wire rope, between the at least two strands so the wire rope has a substantially greater diameter at the crossings of said at least two strands than where said lay is exposed exteriorly of the wire rope.
Claim 2
Dependent Claim
