Abstract
To join together at least two light dividing walls, resisting tensile forces and possibly curved, recourse is had to a plurality of fastenings (4,5) each extending radially in at least one direction from a pivot (6), the pivots of these fastenings being stacked axially along the axis L corresponding to the line of intersection of the mean surfaces of the dividing walls and the contiguous fastenings of the stack being oriented so that they extend alternately along said mean surfaces. The fastenings thus joined together at the level of the pivots form discontinuous wall portions whose roots are mutually imbricated, to which wall portions the dividing walls are then butt-jointed, themselves formed by parallel skins bonded to these wall portions and in which the intermediate space is filled in with foam.
