Abstract: A fastening assembly of a fire door to a bulkhead includes a shaped frame, to which is hinged the door, which includes a first bracket facing at least in part a first side surface of the bulkhead, and a primary flange, mechanically connected to the first bracket. The fastening assembly has a subframe, which in turn includes a second bracket, parallel to the first bracket and facing a second side surface of the bulkhead, and at least one secondary flange, mechanically connected to the second bracket. At least one joint mutually connects the frame and the subframe, to retain the bulkhead between the first and the second bracket mutually facing, without engaging simultaneously the bulkhead the portion of the first bracket facing the first side surface and the portion of the second bracket facing the second side surface.

Abstract: A floating connection assembly of a bulkhead to at least one element of constraint includes a projection integral to the element of constraint and at least one first longitudinal sealing bead. At least one projecting element protrudes from the bulkhead. The assembly has at least a second flexible seal and at least one closure plate, arranged in such a way that the bulkhead and the element of constraint are separated along an edge of the bulkhead. The one first longitudinal sealing bead is interposed between the bulkhead and the projection, on which is present at least one through hole through which passes the projecting element, integral with a respective closure plate, so that the bulkhead remains cantilevered on the protrusion, avoiding a different support, and so that the projecting element is free to oscillate inside the hole.
