SELF-ALIGNING CORNER BEAD FOR FIREPROOFING STRUCTURAL STEEL MEMBER AND METHOD OF USING SAME

摘要

A self-aligning corner bead for fireproofing structural steel, having a strip of welded wire fabric cut to the appropriate width for the fireproofing thickness and bent longitudinally to form an obtuse V-shaped device is disclosed. A plastic nosing is installed along one edge. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the first wing of an obtuse V-shaped device through a lathe to the structural steel member utilizing pneumatic or screw type fasteners. The mesh structure of the second wing of the V-shaped device provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

主权项

1. A corner bead for fireproofing structural steel member along two surfaces, said corner bead comprising:
a strip of welded wire fabric having pre-determined width, said strip bent along its longitudinal axis, said longitudinal axis to define a first wing and a second wing, said first wing and said second wing forming an angle of approximately more than 90 degrees but less than approximately 180 degrees; and wherein said second wing's outer edge comprises a substrate forming a nose, said nose providing a rigid edge of dam-like functionality.
