Embodiment Construction

[0026] refer to image 3 , the corner bead 10 includes a plurality of longitudinal ribs 16 that are substantially parallel to and arranged parallel to each other with respect to a plurality of longitudinal axes including the longitudinal axis A, and distributed between the plurality of longitudinal axes and the plurality of longitudinal ribs 16 A plurality of transverse ribs 18 extend therebetween and substantially perpendicular to the plurality of longitudinal axes and the plurality of longitudinal ribs 16 . A set of void areas 20 is defined by the plurality of longitudinal ribs 16 and the plurality of transverse ribs 18 such that each void area 20 is bounded by at least two longitudinal ribs 16 and at least two transverse ribs 18 . A section of corner bead 10 comprises a single piece of welded wire mesh cut to a predetermined length L and a predetermined width W. As shown in FIG. The predetermined length L and the predetermined width W correspond to a predetermined fireproo...

Abstract

The present invention discloses a self-aligning, double wire corner bead for fireproofing structural steel along a plurality of surfaces. The corner bead has 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 by 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.

Description

technical field [0001] The present invention relates generally to corner bead for cemented fireproofing of steel structures, and more particularly to a device that self-aligns during installation and allows for accurate gauging of fireproofing material thickness along three surfaces. Background technique [0002] In the field of corner bead for fire protection of structural steel, previous approaches generally consisted of a V-shaped curved corner bead with adjustable sides (flanges). These corner strips are mostly used in plastering and painting industries. Previously used corner bead such as figure 1 Shown is made of wire mesh welded into a mesh of V-section. [0003] Such as figure 2 As shown, in the installation, the longitudinal base mesh of the V-shaped corner bead is attached to the metal lath or wire mesh grid with the binding wire mesh, and further attached to the steel member to be fireproofed. After taking into account the correct height of the two flanges, t...
