Title (EN) BOLT TENSIONING ASSEMBLY AND METHOD FOR TENSIONING OF A BOLT
(FR) ENSEMBLE DE SERRAGE DE BOULON ET PROCÉDÉ DE SERRAGE D'UN BOULON
Abstract:
(EN) A bolt tensioning assembly (4) is described, the bolt tensioning assembly (4) comprising: - a bolt (1 ) comprising a first end portion (11) and a second end portion (12) at an opposite side of the bolt (1 ), wherein the first end portion (11) is provided with an enlarged diameter to form a counter-pressure surface (13) facing the second end portion (12); and wherein the first end portion (11) is further provided with external threads to receive a lock nut (2); - a hydraulic bolt tensioning device (3) for tensioning of the bolt (1), the hydraulic bolt tensioning device (3) being arranged for enclosing a portion of the bolt (1) such that it abuts the counter pressure surface (13); and - a lock nut (2) arranged on the first end portion (11) of the bolt (1); wherein the hydraulic bolt tensioning device (3) and the lock nut (2) are dimensioned such that upon tightening of the lock nut (2), the lock nut (2) will tighten against a portion of the hydraulic bolt tensioning device (3). Furthermore there is described a bolt tensioning device (3) in the bolt tensioning assembly (4), and a method for tensioning of the bolt (1).
(FR) L'invention concerne un ensemble de serrage de boulon (4), - l'ensemble de serrage de boulon (4) comprenant : un boulon (1) comprenant une première partie extrémité (11) et une seconde partie extrémité (12) sur un côté opposé du boulon (1), la première partie extrémité (11) présentant un diamètre élargi en vue de former une surface de contre-pression (13) faisant face à la seconde partie extrémité (12) ; et la première partie extrémité (11) présentant en outre des filetages externes en vue de recevoir un écrou de verrouillage (2) ; - un dispositif de serrage de boulon hydraulique (3) pour serrer le boulon (1), le dispositif de serrage de boulon hydraulique (3) étant agencé pour enfermer une partie du boulon (1) de sorte qu'elle vienne en butée contre la surface de contre-pression (13) ; - et un écrou de verrouillage (2) agencé sur la première partie extrémité (11) du boulon (1) ; le dispositif de serrage de boulon hydraulique (3) et l'écrou de verrouillage (2) étant dimensionnés de sorte que lors du serrage de l'écrou de verrouillage (2), l'écrou de verrouillage (2) se resserre contre une partie du dispositif de serrage de boulon hydraulique (3). L'invention concerne également un dispositif de serrage de boulon (3) dans l'ensemble de serrage de boulon (4) et un procédé de serrage du boulon (1).
