Title (DE) STAHLDRAHT ZUR VERSTÄRKUNG DES EINBETTUNGSMATERIALS, INSBESONDERE BETON, SOWIE DAS VERFAHREN ZUR HERSTELLUNG DES STAHLDRAHTS
(EN) STEEL WIRE FOR REINFORCING THE EMBEDDING MATERIAL, ESPECIALLY CONCRETE, AND PROCESS FOR MAKING IT
(FR) CABLE EN ACIER POUR LE RENFORCEMENT DE MATERIAUX D'ENROBAGE, NOTAMMENT DE BETON, ET PROCEDE DE FABRICATION DE CE CABLE
Abstract:
(DE) Stahldraht zur Verstärkung von Einbettungsmaterialien, insbesondere Beton, dadurch gekennzeichnet, daß die Konturlinie (4) des Querschnitts eine dreiarmige Epitrochoide ist, desweiteren allmählich sich ausstaltendes und verschwindendes, entlang dreier Erzeugendestreifen liegendes Gerippe (5) mit konstanter Gewindesteigung aufweist, dessen maximale Tiefe der Differenz zwischen dem Radius (rk) des anschreibbaren kreises des Querschnitts und dem Radius (rb) des einschreibbaren kreises entspricht.
(EN) Steel wire for reinforcing embedding materials, especially concrete, in which the outline (4) of the cross-section is a three-branched epitrochoid which also has gradually widening and disappearing ribbing (5) along three generatrices with a constant increase in thread pitch, the maximum depth of which corresponds to the difference between the radius (r¿k?) of the circle which can be described around the cross-section and the radius (r¿b) of that which can be inscribed in it.
(FR) Câble en acier pour le renforcement de matériaux d'enrobage, notamment de béton, caractérisé en ce que la courbe du contour (4) de la section est une épitrochoïde à trois branches, et présente en outre un profil (5) à pas constant, s'enflant et disparaissant progressivement le long de trois génératrices, dont la profondeur maximale correspond à la différence entre le rayon (rk) du cercle décrit de la section et le rayon (rb) du cercle inscrit.
