Title (EN) SEISMIC SUSPENDED CEILING SYSTEM
(FR) SYSTÈME DE PLAFOND SUSPENDU PARASISMIQUE
Abstract:
(EN) The invention provides suspended or "dropped" ceiling systems based upon the use of standard inverted T-bar lattices. The ceiling panels are constructed from two pieces which, when assembled in place, capture the T-bar in a manner that prevents the panels from shaking loose. A suspended ceiling assembled with the panels of this invention will withstand the forces of an earthquake without experiencing panel drop-outs, and the ceiling will remain intact so long as the T-bars remain suspended from the structural ceiling above. The panels of the invention can, in preferred embodiments, carry lighting fixtures, and the required wiring can be installed and concealed below the T-bars rather than within the plenum.
(FR) L'invention concerne des systèmes de plafond suspendu ou "lâché" reposant sur l'utilisation de réseaux de barres en T inversés standard. Les panneaux de plafond sont construits à partir de deux pièces qui, lorsqu'elles sont assemblées en position, capturent la barre en T d'une manière qui empêche les panneaux de trembler. Un plafond suspendu assemblé aux panneaux de la présente invention résiste aux forces d'un tremblement de terre sans subir de chutes de panneau, et le plafond reste intact tant que les barres en T restent suspendues au plafond structural ci-dessus. Les panneaux selon l'invention peuvent, dans des modes de réalisation préférés, supporter des appareils d'éclairage, et le câblage requis peut être installé et caché sous les barres en T plutôt qu'à l'intérieur du plénum.
