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.

Claims

1. A reinforcement cable comprising a central wire and spiral wires of periodical profile wound around it, wherein:

a periodical profile is designed as inclined protrusions above a generating line of the compressed surface of the cable;

wire surface areas in contact with other wires are made in the form of spirally arranged flat areas;

a periodical profile is applied to an outer surface area of the wound wires; and

gaps between a 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.

2. The reinforcement cable according to claim 1, wherein the wires are positioned so that the tangent contour connecting the outer portions of the wound wires is close to a polygon with rounded corners.

3. The reinforcement cable according to claim 1, wherein the wires are positions so that the tangent contour connecting the outer portions of the wound wires is close to a triangle or a polygon with rounded corners.
