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.

Dependent claims

A floating connection assembly of a bulk-head to at least one element of constraint, the bulkhead having a first face delimited by edges;

said assembly comprising:
a protrusion integral to the element of constraint;
at least one first longitudinal sealing bead;
at least one projecting element projecting from the bulkhead or from the protrusion;
at least a second flexible seal;
and
at least one closure plate;
wherein:
the bulkhead and the coupling element are mutually separated by a separation distance along an edge of the bulkhead so that the bulkhead and the constraint element are connected only indirectly, by said floating assembly;
said protrusion has a second face and a third face parallel and opposite to each other, said second face being parallel and spaced apart with respect to the first face of the bulkhead;
the first longitudinal sealing bead is interposed between the first face of the bulkhead and the second face of the protrusion;
the protrusion or the bulkhead comprises at least one through hole on the second face of said protrusion or on the first face of the bulkhead;
the at least one closure plate is concentric with respect to said through hole, and parallel and spaced apart with respect to the third face of the protrusion or to the bulkhead;
the second flexible seal is interposed between the closure plate and the third face of the protrusion or between the closure plate and the bulkhead;
the at least one projecting element protrudes from the first face of the bulkhead or from the second face of said protrusion, is axially inserted in a respective through hole, and is integral with a respective closure plate, so that the bulkhead remains cantilevered on said protrusion, avoiding a different support;
and
the projecting element has a diameter smaller than a diameter of the respective hole, so that said projecting element is freely floatable inside the through hole in a radial direction.

14 more elements

A method for decoupling a bulkhead from at least one element of constraint to limit stresses exchanged between said bulkhead and said at least one element of constraint, said bulkhead comprising a first face delimited by edges, and said method comprising the steps of:

a) positioning the bulkhead at a separation distance from the element of constraint, so that the bulkhead and the element of constraint are separated along an edge of said bulkhead;
b) providing a protrusion, comprising a second face and providing at least one through hole, formed on said second face, or on the first face of the bulkhead;
c) securing the protrusion to the element of constraint, so that the second surface of said protrusion is parallel to the first surface of the bulkhead, and transversely spaced from said first surface;
d) applying at least one longitudinal sealing bead in a position interposed between the first face of the bulkhead and the second face of the protrusion;
e) securing at least one projecting element to the bulkhead, so that said projecting element protrudes transversely from the first face of the bulkhead and inserts axially in a respective hole of the protrusion or, vice-versa, so that said projecting element protrudes transversely from the second face of the protrusion and inserts axially in a respective hole of the bulkhead said projecting element being radially floatable inside the hole;
f) positioning a closure plate parallel to the protrusion and concentrically with respect to a respective through hole;
and
g) connecting said closure plate to the protrusion or the bulkhead by a second flexible peripheral seal, interposed between said closure plate and said protrusion or between said closure plate and said bulkhead so that the projecting element completely passes through the hole and is integral with the closure plate.
