The invention relates to a device (18, 61), in particular a connection rod (1, 19), for bracing a fuselage structure (9, 10, 27, 28, 45, 74) and/ or for fastening components on the fuselage structure (9, 10, 27, 28, 45, 74). In one embodiment, the joints (29, 30, 53) are integrated into fuselage structure (9, 10, 27, 28, 45) for linking on both sides of connection rod (1, 19) to fuselage structure (9, 10, 27, 28, 45). As a result of the integration of joints (29, 30, 53), a reduced number of individual parts is produced in comparison to previously known embodiments, which leads to a reduction in weight, a reduced maintenance and servicing outlay and an improved reliability against failure. Moreover, device (18, 61) according to the invention enables the introduction of forces in the region of neutral fibres (43, 44) of fuselage structure (9, 10, 27, 28, 45, 74). A further configuration of device (61) provides only a one-sided articulated linking of a component (65) to fuselage structure (74) by means of (first) end portion (63). Second end portion (64) is screwed to fuselage structure (74). To this end, both end portions are provided with a thread at least in sections.

L'invention concerne un dispositif (18, 61), notamment une bielle (1, 19), permettant d'étrésillonner une structure (9, 10, 27, 28, 45, 74) de fuselage et/ou de fixer des composants sur la structure (9, 10, 27, 28, 45, 74) de fuselage. Dans un mode de réalisation, des joints (29, 30, 53) sont incorporés à la structure (9, 10, 27, 28, 45) de fuselage pour rattacher les deux extrémités de la bielle (1, 19) à la structure (9, 10, 27, 28, 45) de fuselage. L'incorporation des joints (29, 30, 53) permet de réduire le nombre de pièces individuelles par rapport aux modes de réalisation connus, d'où une réduction du poids et des coûts d'entretien et de réparations et une fiabilité accrue vis-à-vis des défaillances. De plus, le dispositif (18, 61) de l'invention permet d'introduire des forces dans la région de fibres neutres (43, 44) de la structure (9, 10, 27, 28, 45, 74) de fuselage. Une autre configuration du dispositif (61) comprend uniquement une liaison articulée d'un seul côté entre un composant (65) et la structure (74) de fuselage via une (première) partie d'extrémité (63). La deuxième partie d'extrémité (64) est vissée sur la structure (74) de fuselage. A cet effet, les deux parties d'extrémité sont pourvues d'un filetage au moins sur certains segments.
