REINFORCEMENT ROPE AND METHOD OF ITS MANUFACTURING Russian patent published in 2011 - IPC E04C5/03 D07B1/00 

FIELD: construction.

SUBSTANCE: reinforcement rope consists of a central wire 1 (dwg.1), around which there are winding wires 2 wound. Surface sections of wires 2, contacting with each other and the surface of the wire 1, are made in the form of spirally arrange flat sites 3. On the external section of the rope wires 2 surface there is a periodical profile applied, made as inclined ledges 4 above the generatrix 5 of the pressed surface of the rope. The wires 1 and 2 are arranged so that the contour that connects external sections of winding wires along the tangent is brought near a triangle with rounded corners, for instance, according to the pattern 1+6+3. The reinforcement rope is made in the following manner. Wires 1 and 2 of round section are made and wound into a rope. After the winding, a periodical profile is applied onto the external section of the rope wires 2 by means of cold deformation along the external surface of the wires 2 in the closed shaped roller calibre of the periodical profile. Simultaneously with application of the periodical profile on the rope surface in the specified calibre, plastic pressing of the rope is carried out, as a result contact sites 3 are formed.

EFFECT: development of a self-straightening reinforcement element of large length with the ratio of strength and dimensions of the section at the level of the reinforcement steel of classes A500 and A600, other characteristics not lower than the reinforcement steel of classes A500 and A600.
