Abstract

Die Klemm- und Spannhalterung für den temporären Einsatz an Verstärkungsstäben mit kreisrundem Querschnitt und zugehörigen Verstärkungsstäben (4) besteht aus einer Hülse (1), die einen Innenkonus (11) bildet, sowie aus einem zugehörigen Klemmstück (2), welches einen in den Innenkonus (11) der Hülse (1) einsteckbaren Außenkonus bildet. Das Klemmstück (2) besteht aus mindestens drei Klemmbacken (3), die je ein Konussegment bilden, welche Konussegmente den Verstärkungsstab (4) unter Freilassung radialer Spalten (6) zu umfassen bestimmt sind. Auf ihrer Innenseite weisen die Segmente je ein Zylinderwandsegment (5) mit um 10% kleinerem Radius als jenem des Querschnittes des Verstärkungsstabes (4) auf. Die Oberfläche des zugehörigen Verstärkungsstabes (4) ist mit einer keramischen Sandbeschichtung mit bestimmter Korngröße und Kornhärte ausgerüstet.The clamping and clamping holder for the temporary use of reinforcing rods with a circular cross-section and associated reinforcing bars (4) consists of a sleeve (1), which forms an inner cone (11), and of an associated clamping piece (2), which in the inner cone (11) of the sleeve (1) forms an insertable outer cone. The clamping piece (2) consists of at least three clamping jaws (3), each of which forms a cone segment, which cone segments are intended to surround the reinforcing rod (4) while leaving free radial gaps (6). On their inside, the segments each have a cylinder wall segment (5) with 10% smaller radius than that of the cross section of the reinforcing rod (4). The surface of the associated reinforcing rod (4) is equipped with a ceramic sand coating with a certain grain size and grain hardness.
