Both members are in the form of I-beams having a central web and top and bottom flanges projecting at opposite sides of the web, and the top flanges of the main members have depending lips at their edges.Each joint construction includes a notch in a depending lip capable of receiving the web of a cross member, and opposed slots in the top flange of the end portion of the cross member capable of receiving portions of depending lip on each side of the notch. The lower flange and web of the cross member end portion are configured to allow the lip to be interlocked with the slots by a relative tilting motion between the cross member and the main member, and the cross member rests on the main member lower flange when the parts are in their final position.
Nouveau modèle de joint pour raccorder les éléments longitudinaux et transversaux d'un faux-plafond. Les deux éléments sont des profilés en I munis d'une âme centrale et de semelles supérieure et inférieure se prolongeant sur les côtés opposés de l'âme, les semelles supérieures des éléments longitudinaux comportant des lèvres dépendantes sur leurs rebords. Chaque joint comprend une encoche dans une lèvre dépendante capable de recevoir l'âme d'un élément transversal, et des fentes opposées dans la semelle supérieure de l'extrémité de l'élément transversal capables de recevoir des parties de la lèvre dépendante sur chaque côté de l'encoche. La semelle inférieure et l'âme des parties inférieures de l'élément transversal sont configurées pour permettre à la lèvre de s'imbriquer avec les fentes par un enclenchement relatif entre l'élément transversal et l'élément longitudinal, et l'élément transversal repose sur la semelle inférieure de l'élément longitudinal lorsque les parties sont dans leur position finale.
