Abstract
Official abstract text for this publication.
The present invention relates to a cable using cold-drawn shape memory alloy wires, which facilitates concrete prestressing or other operations, and has excellent adhesion to concrete and manufacturability. The cable using cold-drawn shape memory alloy wires includes: a core wire configured by a cold-drawn shape memory alloy deformed by cold drawing to have an increased length; and a plurality of peripheral wires configured by cold-drawn shape memory alloy wires which are deformed by cold drawing to have an increased length and are couple to the core wire while being wound in a same direction along the circumference of the core wire.
First claim
Opening claim text (preview).
What is claimed is: 1. A cable using cold-drawn shape memory alloy wires to be used in a construction site, the cable comprising: a core wire configured by a cold-drawn shape memory alloy deformed by cold drawing to have an increased length; and a plurality of peripheral wires coupled to the core wire while being wound in a same direction along the circumference of the core wire, and configured by cold-drawn shape memory alloy deformed by cold drawing to have an increased length wherein the core wire is formed using a cold-drawn shape memory alloy straight wire configured straightly or a cold-drawn shape memory alloy corrugated wire having corrugations formed on a surface thereof, the plurality of peripheral wires are formed using cold-drawn shape memory alloy corrugated wires having corrugations formed on a surface thereof, and the cable is configured to be used while being confined in a concrete or in a cement composite material in the construction site, resulting that, in the construction site, there is no need to directly tensioning the cable to deform. 2. A combined cable having a first cable and a plurality of second cables according to claim 1 , wherein the plurality of second cables are wound in a same direction along the circumference of the first cable.
