Benefits of technology

The patent describes a head-of-wall assembly for providing fire, smoke, and sound protection across a building joint. The assembly includes a fluted pan deck with a flute void and a header track attached to the deck. A stud attaches with the header track and includes an upper end that overlaps the flute void. A pre-formed plug is placed within the flute void and is supported by the header track. The plug has a fire-resistant material and an outer coating that compresses and expands the material. The assembly also includes an outer perimeter that extends about the plug. The technical effects of the invention include improved fire protection, reduced smoke and sound transmission, and simplified installation.

Problems solved by technology

Building joints, such as head-of-wall joints can be labor intensive and / or time-consuming to fireproof using conventional methods.
This makes both installation of any firestopping materials and inspection of the firestopping materials a challenge.
This application is messy and can coat or spray the MEPs located at the head of wall.

Embodiment Construction

[0016]Head-of-wall joints that protect against fire, smoke, and / or noise (generically “firestopping joints”) can be difficult (e.g., labor intensive and / or time-consuming) to install. For example, firestopping joints can be located at the top or head of wall and are typically surrounded by electrical conduits, mechanical ducts, data lines, and plumbing (MEPs) leaving very little working room. This makes both installation of the firestopping materials and inspection of the firestopping materials a challenge. For this reason, the building industry is turning to “device” firestopping. Firestop devices are products that are fully cured and / or ready to use. The firestopping material is contained within the device and the devices can be mechanically attached with or friction fit into the joint at a void or opening. An example of a head-of-wall assembly is discussed in U.S. Pat. No. 8,087,205, the entirety of which is hereby incorporated by reference.

Abstract

A pre-formed flute plug including compressed fire-resistant material (e.g., mineral wool) for fireblocking a head-of-wall assembly. The plugs can be pre-formed to shape and include an outer coating that contains the compressed fire-resistant material inside. Once installed within a flute void, the outer coating can be ruptured to allow expansion of the fire-resistant material to fill the flute void.

Description

CROSS REFERENCE[0001]This application claims the benefit of U.S. Patent Application No. 63 / 076,801, filed Sep. 10, 2020, the entirety of which is hereby incorporated by reference.BACKGROUNDField[0002]This disclosure generally relates to devices, systems, and methods for proofing a building joint against the passage of smoke, fire and / or noise.Related Art[0003]Building joints, such as head-of-wall joints can be labor intensive and / or time-consuming to fireproof using conventional methods. For example, firestopping joints located at the top or head of a wall are typically surrounded by electrical conduits, mechanical ducts, data lines, and plumbing (MEPs) leaving very little working room. This makes both installation of any firestopping materials and inspection of the firestopping materials a challenge. When fluted pan decking is used, open voids are located at the head-of-wall joint. A common technique for fire-stopping the open voids is to fill the voids with mineral wool and then s...
