Abstract

L'invention concerne l'utilisation de pièces métalliques en alliage à mémoire de forme, par exemple en nickel et titane, pour le blocage des plaques de plafonds suspendus dans leur ossature apparente, lorsque leur température atteint la valeur critique qui peut etre de 70 degrés C par exemple. Il est constitué de profils ''Tés''(1) existant sur le marché, sur l'ame (2) duquel viennent se fixer les pièces métalliques à mémoire de forme (3), par exemple en alliage nickel et titane, qui par leur déformation programmée à une température critique de l'ordre de 70 degrés C, bloquent les plaques de plafonds suspendus (4). Le dispositif est destiné à la protection incendie des batiments par plafonds suspendus sur ossature apparente.The invention relates to the use of metal parts made of shape memory alloys, for example nickel and titanium, for blocking suspended ceiling plates in their visible framework, when their temperature reaches the critical value which can be 70 degrees. C for example. It is made up of “Tee” profiles (1) existing on the market, on the core (2) of which are fixed the metal parts with shape memory (3), for example made of nickel and titanium alloy, which by their programmed deformation at a critical temperature of the order of 70 degrees C, block the suspended ceiling plates (4). The device is intended for fire protection of buildings by suspended ceilings on exposed framework.
