AI Technical Summary

Benefits of technology

The present invention provides an improved method for creating fire-rated wall joints by using a fire-rated angle piece that incorporates a fire-resistant or intumescent material on at least one surface. This angle piece can be installed prior to the installation of the wall board and is separate from the header track. It can be easily installed and stacked without damaging the intumescent material and can be shipped without difficulty. The technical effect of this invention is to provide a more efficient and cost-effective method for creating fire-rated wall joints.

Problems solved by technology

This conventional construction of a fire-rated head-of-wall joint is time-consuming, expensive and has other disadvantages that are described herein.
If the wall studs are rigidly attached to the slotted track and not allowed to move freely in at least one direction, the stability of the wall and the building might be compromised.

Embodiment Construction

[0108]Several preferred embodiments of the fire-rated angle pieces and fire-rated joint systems are described herein, typically in the context of a wall assembly and, in particular, a head-of-wall assembly. However, the fire-rated angle pieces and fire-rated joint systems can also be used in other applications, such as at the bottom or sides of a wall or a joint in an intermediate location of a wall. The fire-rated angle pieces and fire-rated joint systems can also be used in non-wall applications. In view of the head-of-wall assembly being but one of the multiple applications for the fire-rated angle pieces and fire-rated joint systems, the use of relative or directional terminology, or other such descriptions, is for convenience in describing the particular embodiments, arrangements or orientations shown. Therefore, such terms are not intended to be limiting, unless specifically designated as such.

Abstract

A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece can include an intumescent or other fire-resistant material strip. The angle can be attached adjacent to a corner of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the angle piece.

Description

RELATED APPLICATIONS[0001]Related applications are listed in an Application Data Sheet (ADS) filed with this application. All applications listed in the ADS are hereby incorporated by reference herein in their entireties.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention generally relates to fire-rated building structures. In particular, the present invention relates to fire-rated joint systems, wall assemblies, and other building structures that incorporate the fire-rated joint systems.[0004]Description of the Related Art[0005]Fire-rated construction components and assemblies are commonly used in the construction industry. These components and assemblies are aimed at preventing fire, heat, and smoke from leaving one room or other portion of a building and entering another room or portion of a building. The fire, heat or smoke usually moves between rooms through vents, joints in walls, or other gaps or openings. The fire-rated components often incorpo...
