1. A joint assembly including:
a first component with a flange containing a plurality of spaced through-holes, a second component with a joining portion having an end surface which faces the flange, the joining portion containing a plurality of spaced elongate cavities, each elongate cavity extending into the joining portion from the end surface in axial alignment with a respective one of the through-holes, and a plurality of fixation devices, each fixation device including a bolt with a shank which extends through a respective through-hole and the corresponding aligned elongate cavity, and further including a nut having a curved outer surface which is embedded within a curved recess in the joining portion within the corresponding elongate cavity to threadingly receive the shank such that on tightening the nut and the bolt a clamping force is exerted across the flange and the end surface to join the first and second components, wherein:
each fixation device is configured such that under axial loads less than those causing bolt failure the fixation device is deformable to remove the clamping force across the flange and the end surface;the curved outer surface of the nut and the curved recess in the joining portion are configured to prevent movement of the nut relative to the curved recess in a direction parallel to a longitudinal direction of the shank, and permit a sliding rotation of the nut within the curved recess relative to the joining portion; andthe curved recess is provided in a housing embedded within the joining portion and is in communication with the elongate cavity of the second component. |
