Abstract

Procedimiento para la fabricación de una barra de armadura para hormigón, en que una barra, producida por laminado en caliente, de sección transversal redonda, por deformación en frío, experimenta una disminución de la sección transversal y en su contorno se provee de nervios, situados oblicuamente a su eje, caracterizado porque la barra en 2- 4 lugares , situados sobre el contorno de modo uniformemente distribuido, por laminado en frío se provee, en dirección axil, de aplanamientos, cada uno de los cuales presenta una anchura de 10- 30% del diámetro de la barra y porque entonces las partes del contorno, existentes entre los aplanamientos, por laminado en frío, se proveen de los nervios de tal clase que los flancos de los nervios en el fondo, situado entre los nervios en dirección axil y los extremos de los nervios pasan en esencia constantemente en transición a la superficie no nervada, situada entre dos nervios en dirección periférica.Procedure for the manufacture of a reinforcing bar for concrete, in which a bar, produced by hot rolling, with a round cross-section, by cold deformation, undergoes a decrease in cross-section and its contour is provided with ribs, located obliquely to its axis, characterized in that the bar in 2-4 places, located on the contour in a uniformly distributed way, by cold rolling is provided, in the axial direction, with flattening, each of which has a width of 10-30 % of the diameter of the bar and because then the contour parts, existing between the flattenings, by cold rolling, are provided with ribs of such a kind that the flanks of the ribs at the bottom, located between the ribs in the axial and the ends of the ribs pass essentially constantly in transition to the non-ribbed surface, situated between two ribs in the peripheral direction.
