Abstract
A self-aligning, double wire corner bead for fireproofing structural steel along a plurality of surfaces, the corner bead having a single strip of welded wire fabric cut to a predetermined width for the fireproofing thickness and bent along a plurality of longitudinally extending lines, to provide a profile having a plurality of dihedral angles is disclosed. A nose is installed along two edges. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the corner bead through a lath to the structural steel member utilizing fasteners. The mesh of the corner bead provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.
Claims7
A corner bead for fireproofing a member along a set of surfaces of the member, comprising:
- a welded wire fabric;
- a set of bends integrally formed in the welded wire fabric;
- a first wing defined by the set of bends;
- a single wire membrane defined by the set of bends, adjacent to the first wing;
- a double wire membrane defined by the set of bends, adjacent to the single wire membrane;
- a second wing defined by the set of bends, adjacent to the double wire membrane;
- a set of generally planar surfaces defined by the first wing and the second wing;
- and,
- wherein the welded wire fabric is only fastened to the member at a first fastening position on the double wire membrane.
