Title
(DE) VORRICHTUNG ZUR DREHMOMENTBEGRENZUNG MIT DREI STEGEN
(EN) TORQUE LIMITATION DEVICE HAVING THREE WEBS
(FR) DISPOSITIF DE RÉGULATION DE COUPLE À TROIS ORGANES DE LIAISON
Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zur Drehmomentbegrenzung aufweisend ein Halteelement für eine Mutter oder einen Schraubenkopf, wobei das Halteelement in einem rückwärtigen Bereich des Halteelements ein Kopfteil mit einem Mitnahmeprofil zur drehfesten Kopplung des Kopfteils mit einem Setzwerkzeug aufweist, und das Halteelement in einem vorderen Bereich des Halteelements ein Aufnahmeteil mit einer Aufnahme zum drehfesten Aufnehmen der Mutter beziehungsweise des Schraubenkopfs aufweist. Erfindungsgemäss ist vorgesehen, dass das Halteelement drei drehmomentübertragende Stege aufweist, welche das Aufnahmeteil und das Kopfteil verbinden, und welche eine Sollbruchstelle bilden. Die Erfindung betrifft ferner eine Befestigungsanordnung bestehend aus einer solchen Vorrichtung und einem Spreizanker.
(EN)
The invention relates to a device for torque limitation, having a holding element for a nut or a screw head, wherein the holding element has, in a rear region of the holding element, a top part having a driver profile for the rotationally fixed coupling of the top part to a setting tool, and the holding element has, in front region of the holding element, a receiving part with a receptacle for the rotationally fixed reception of the nut or the screw head. According to the invention, the holding element has three torque-transmitting webs, which connect the receiving part and the top part and which form an intended fracture point. The invention further relates to a fixing arrangement comprising such a device and an expansion anchor.
(FR)
L'invention concerne un dispositif de régulation de couple présentant un élément de retenue pour un écrou ou une tête de vis, l'élément de retenue présentant, dans une zone arrière de l'élément de retenue, une partie tête possédant un profil d'entraînement permettant l'accouplement solidaire en rotation de la partie tête avec un outil de réglage, l'élément de retenue présentant, dans une zone avant de l'élément de retenue, une partie logement comportant un logement destiné à la réception solidaire en rotation de l'écrou ou de la tête de vis. Selon l'invention, l'élément de retenue présente trois organes de transmission de couple, lesquels relient la partie logement et la partie tête, et forment un point de rupture. L'invention concerne également un système de fixation comprenant un tel dispositif et un boulon d'ancrage.
