US 2012/0240548 A1 · REINFORCEMENT CABLE

Abstract

The invention pertains to the production of cables and can be used for reinforcing single-block constructions and other articles made of concrete. The purpose of the invention is to create a self-rectifying reinforcing member. The reinforcement cable comprises a central wire and layer-forming wires spirally wound around the same and having a periodical profile. A periodical profile is applied on the outer section of the surface of the layer-forming wires and is made in the form of inclined protrusions above the generatrix of the crimped surface of the cable. The sections of the surface of the layer-forming wires in contact with other wires are made in the form of spirally-arranged planar flats. The cable is secured at the base of the structure and is attached upon each casting cycle between the previously-formed portion of the structure and a distribution matrix. The cable is supplied via bypass rollers and a guiding trough from reels arranged at the base. Before each casting cycle, the matrix is moved by a distance corresponding to a section to be formed. Each reinforcing member is integral along the entire length of the structure. The connection of perpendicular members is made using inserts or a tie wire.

Dependent claims

A reinforcement cable comprising a central wire and spiral wires of periodical profile wound around it, said cable characterized in that:

the wires of said cable have tensile strength which is two or more times higher than that of hot-rolled reinforcement rods of the equal diameter;
a periodical profile is designed as inclined protrusions above the generating line of the compressed surface of the cable;
the wire surface areas in contact with other wires are made in the form of spirally arranged flat areas;
a periodical profile is applied to the outer surface area of the wound wires;
and
gaps between the cable cross section circumference and the outer wire surfaces have increased size compared to the gaps in a cable with round wires due to the shape of outer wire sections and arrangement of the wires so that the tangent contour connecting the outer portions of the wound wires is close to a triangle with rounded corners, but with no more than one incomplete layer, for example according to the arrangement 1+6+3, 3/3 or 3+3+6+3.
