CA 2626250

A wall angle for a suspended ceiling, which may either be a drywall suspended ceiling or a lay-in tile suspended ceiling, has a cross-section forming a substantially right angle of the vertical leg and a horizontal leg. The horizontal leg is adapted to support an inverted tee-runner that has a vertical web and opposed flanges, the opposed flanges being adapted to rest on the horizontal leg of the wall angle. The horizontal leg is formed with a plurality of pairs of locating tabs, at least one tab in each pair being upwardly extending and vertically-oriented. The tabs in each pair are spaced apart a distance sufficient to accommodate the width of the opposed flanges of the tee-runner. At least one of the tabs in each pair has a downwardly extending detent adapted to permit installation of a tee-runner, but to inhibit removal of the tee-runner. The pairs of tabs are spaced, on center, a pre-determined distance that depends upon the intended application of the wall angle.

Cornière murale pour faux-plafond, qui peut consister soit du type à cloisons sèches ou à carreaux posés à sec; la cornière comporte une coupe transversale qui forme un angle essentiellement droit entre une patte verticale et une patte horizontale. La patte horizontale est adaptée de façon à supporte un coulisseau en T inversé muni d'une armature verticale et des brides opposées, ces dernières étant adaptées de façon à reposer sur la patte horizontale de la cornière murale. La patte horizontale est formée d'une série de paires de languettes de fixation, une languette de chaque paire se prolongeant vers le haut et à une orientation verticale. Les languettes de chaque paire sont espacées à une distance suffisante pour recevoir la largeur des brides opposées du coulisseau en T. Au moins une des languettes de chaque paire comporte un cran se prolongeant vers le bas et adapté de façon à permettre l'installation d'un coulisseau en T, tout en empêchant l'enlèvement dudit coulisseau. Les paires de languettes sont espacées et centrées sur une distance prédéterminée qui dépend de l'utilisation prévue de la cornière murale.
