Sheet aluminum fireproof construction element

A fireproof building element comprising:

• a four-sided panel of nonflammable material with two planar surfaces;
• and
• a four-legged framework of nonflammable material surrounding said panel, each side of said panel being engaged by a leg of said framework having a rectangular cross-section divided in the plane of a surface of said panel into two frame portions together defining a recess accommodating an edge of said panel, said leg including at least one aluminum profile forming two opposite faces of said leg remote from said recess and parallel to said panel, at least one of said frame portions forming a chamber offset from said plane and separated from one of said faces by a sheet-aluminum wall having a thickness of at least one millimeter, said leg further having a core with a cutout receiving said edge of said panel, said edge being embedded in a bead of fireproof nonmetallic material bracketed within said cutout by two aluminum strips, further comprising screw means threaded into said core for exerting clamping pressure upon said strips.

A fire-resistant building element comprising an elongate aluminum profile of four-sided cross-section attachable to a support at one side, said profile having a supporting part attachable to a supported element at the opposite side, said supporting part including an aluminum core terminating at said one side, a third side of said profile being bounded by an aluminum wall substantially thinner than said core spaced from said supporting part and forming with said core a closed chamber protecting said supporting part from fire approaching said third side whereby the connection between said support and said supported element is maintained intact for an extended period.
