Abstract

Die Erfindung betrifft einen Bewehrungsstahl als Einzel­ stabbewehrung und als Gurtstab für die Herstellung von Git­ terträgern insbesondere für Spritzbeton. Um für die Verwen­ dung im Spritzbeton zwischen den Baustoffen einen optimalen Verbund zu erreichen und in diesem Zusammenhang die Spritzschattenbildung auf ein Mindestmaß zu beschränken und die Wasserdurchlässigkeit durch Störstellen am Beton stahl zu vermeiden, wird vorgeschlagen, daß der stabförmige Stahl einen ovalen Querschnitt, dessen Hauptachsen mit dem Nenndurchmesser des Stahls die Beziehung
d₁d₂= (1,05 ÷ 1,20) ds
bilden, wobei ds der Durchmesser des in den ovalen Quer­ schnitt einbeschriebenen Kreises ist, aufweist sowie wenig­ stens zwei Reihen sich quer um seine Längsachse erstrek­ kende, mit seiner Oberfläche ein einheitliches Ganzes bil­ dende, nicht umläufige Rippen, daß die Rippen aufeinanderfol­ gender Reihen gegeneinander versetzt sind und daß wenig­ stens die zwischen den Rippen vorhandene Oberfläche des Stahls eine Rauhtiefe µ = (0,005 ÷ 0,03) ds aufweist. The invention relates to a reinforcing steel as a single bar reinforcement and as a belt rod for the production of Git terträger especially for shotcrete. In order to achieve an optimal bond for the use in shotcrete between the building materials and in this context to minimize the formation of spray shadows and to avoid water permeability due to imperfections on the concrete, it is proposed that the rod-shaped steel have an oval cross-section, the main axes of which the relationship with the nominal diameter of the steel
d₁d₂ = (1.05 ÷ 1.20) d s
form, where d s is the diameter of the circle inscribed in the oval cross-section, and has at least two rows extending transversely about its longitudinal axis, with its surface forming a unified whole, non-circumferential ribs that the ribs of successive rows are offset from each other and that at least the surface of the steel between the ribs has a roughness depth µ = (0.005 ÷ 0.03) d s .
