CA 2544830

An expansion joint for building panels, such as concrete floor slabs, comprises a U-shaped drape of a flexible, fire-resistant, impermeable material such as stainless steel foil. The opposite legs of the U-shaped drape are fastened between respective adjacent slabs and a mat of expandable fire- resistant material inserted within the U-shaped drape between the slabs. The impermeability and flexibility of the drape, coupled with the insulating property of the mat provide an inexpensive, effective fire seal between building panels that can also accommodate seismic displacement.

L'invention porte sur un joint de dilatation coupe feu pour panneaux de construction tels que des dalles de béton consistant en une tôle en U, d'un matériau flexible, résistant au feu et imperméable tel que de l'acier inoxydable, dont les bras opposés se fixent respectivement aux deux dalles contiguës, et entre lesquels on dispose un bourrage d'un matériau expansible et résistant au feu. L'imperméabilité et la flexibilité de la tôle, liées à la propriété isolante du bourrage, donnent un joint coupe feu économique et efficace pouvant en outre absorber les déplacements sismiques.
