Problems solved by technology

All of these approaches, however, are relatively labor intensive and thus expensive.
The use of Z-clips provides a simply solution in this regard, but the use of Z-clips in this manner is time consuming, labor intensive, and inefficient.

Embodiment Construction

[0021]Referring now to the drawings wherein like reference numerals are used to designate like parts and features, the present invention in a first embodiment (and as best shown in FIGS. 1A-B) is directed to an offset leg framing element for use in a fire rated assembly (of a building). The offset leg framing element 10 comprises a web section 12 having opposing edges 14, 16, and a pair of outwardly extending sidewalls 18, 20 integrally connected to the web section 12. As shown, each sidewall 18, 20 has a proximal end 22 and a distal end 24, wherein the proximal end 22 of each sidewall 18, 20 is integrally connected to one of the opposing edges 14, 16 of the web section 12, and wherein the sidewalls 18, 20 are substantially parallel and confront each other.

[0022]The offset leg framing element 10 also comprises at least one laterally extending ledge section 26 integrally connected to one of the pair of outwardly extending sidewalls 18, 20. As shown, the at least one ledge section 26 ...

Abstract

The invention disclosed herein is directed to an offset leg framing element for use in a fire rated assembly and comprises: a web section having opposing edges; a pair of outwardly extending sidewalls integrally connected to the web, wherein the sidewalls are substantially parallel and confront each other. In addition, at least one laterally extending ledge section is integrally connected to one of the pair of outwardly extending sidewalls; and at least one downwardly extending leg is integrally connected to the at least one ledge section. The offset leg framing element may be characterized in that the ratio the sidewall height (h1) over the ledge section width (w2) is greater than or equal to one (h1/w2≧1), and wherein the ratio the sidewall height (h1) over the web section width (w1) is greater than or equal to one sixth (h1/w1≧0.1667).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority to U.S. Provisional Application No. 61 / 309,994 filed on Mar. 3, 2010, which application is incorporated herein by reference in its entirety for all purposes.TECHNICAL FIELD[0002]The present invention relates generally to structural wall framing elements and, more particularly, to structural wall framing elements that are sized and dimensioned to facilitate the application of a spray-on fire resistant coating to an underlying support beam substrate and the construction of fire rated partitions, as well as to related wall assemblies.BACKGROUND OF THE INVENTION[0003]Metal framing assemblies are commonly used to construct commercial and residential buildings in the building construction industry. Such metal framing assemblies are generally constructed from a plurality of metal framing members including studs, joist, trusses, and other metal posts and beams formed from sheet metal and frequently ...
