A joint (40) for joining a first metal sheet (10) to a second metal sheet (30) comprises a plurality of deformable projections (14) on an edge (12) of the first metal sheet (10). Each deformable projection (14) has an aperture (16) therethrough to form two sides (18, 20) and a deformable head (22). The sides (18, 20) have dogs (24, 26). A plurality of slots (32) are provided through the second metal sheet (30). The deformable projections (14) extend through the slots (32) in the second metal sheet (30). The deformable projections (14) are deformed such that the head (22) of the deformable projection (14) expands the dogs (18, 20) of the deformable projections (14) beyond the sides (34, 36) of the slots (32) to prevent withdrawal of the deformable projections (14) from the slots (32) in the second ductile sheet (30).
L'invention concerne un joint (40) permettant d'assembler une première feuille métallique (10) avec une seconde en feuille métallique (30), comprenant une pluralité de saillies déformables (14) sur un bord (12) de la première feuille métallique (10). Chaque saillie déformable (14) possède une ouverture (16) de façon à former deux côtés (18, 20) et une tête déformable (22), lesdits côtés (18, 20) comprenant des agrafes (24, 26). Une pluralité de fentes (32) traversent la seconde feuille métallique (30). Les saillies déformables (14) traversent les fentes (32) de ladite seconde feuille métallique (30). Ces saillies déformables (14) sont déformées de sorte que la tête (22) d'une saillie déformable (14) dilate les agrafes (18, 20) desdites saillies déformables (14) au-delà des côtés (34, 36) des fentes (32) afin d'empêcher le retrait de ces saillies déformables (14) desdites fentes (32) de la seconde feuille (30) ductile.
