Definitions
- the invention relates to building structures and, in particular, to a fire resistant membrane.
- the invention provides an effective fire rated membrane construction for walls, ceilings, mechanical shafts, chases, and like structures that can be assembled from one side of the membrane.
- the construction uses a novel combination of conventional sheet metal framing elements, fire rated wallboard or drywall sheets, and assembly techniques.
- a layer of the fire rated drywall sheets is secured to light gauge steel “C” studs or like framing elements.
- a second fire rated drywall layer and optional successive layers is/are separated from the preceding layers by resilient channels or like elements.
- the channels are oriented at right angles to the studs. The channels allow the successive drywall sheets to be secured with screws that do not penetrate the assembly and, therefore, do not directly transfer heat from one side of the membrane to the other.
- the air space between layers advantageously retards heat transfer from one layer to another thereby adding to the fire rating capacity of the membrane.
- the channels additionally, serve the important function of laterally stabilizing the studs against excessive buckling when they are subject to thermal expansion and their ends are constrained. This stabilizing function can avoid the prior practice of leaving the stud ends spaced from one another or from a receiving track to accommodate thermal expansion and thereby avoid buckling but, unfortunately, limiting the height of the membrane.
- the inventive construction is scalable in the sense that additional protection can be obtained by adding layers of fire rated wallboard with or without intervening channels.
- wallboard and drywall are used interchangeably in the present disclosure.
- FIG. 1 is a fragmentary perspective view of a one-sided fire rated wall membrane constructed in accordance with the invention
- FIG. 2 is a fragmentary plan view of the wall of FIG. 1 ;
- FIG. 3 is a fragmentary side elevational view of the wall of FIG. 1 ;
- FIG. 4 is a fragmentary perspective view of a resilient channel used in the construction of the wall of FIG. 1 ;
- FIGS. 5A , 5 B, and 5 C represent optional alternative bracing arrangements for a wall embodying the invention.
- a membrane or wall such as shown at 10 in the FIGS. is a “one sided construction” meaning that it is assembled by a person or persons standing or otherwise situated on only one side of the membrane. Such one sided construction can be necessitated by certain building areas and/or conditions that limit access to one side of the membrane. Examples of these situations are high rise elevator shafts, utility shafts, chases and reconstruction where the rating of an existing wall is unknown.
- the membrane or wall 10 includes sheet steel “C” studs typically made of light gauge stock and fire rated gypsum wallboard sheets 12 .
- the studs 11 are conventional commercially available items as are the fire rated drywall sheets 12 .
- the drywall sheets are of a thickness of 5 ⁇ 8 in. and are available in a 4 ft.
- the studs 11 can be any commercially available unit typically ranging from 15 ⁇ 8 in. to 6 in. in width and ranging in length, for example, between 8 ft. and 16 ft. Dimensions used herein can be substituted with industry metric equivalents.
- the term membrane, as used herein, comprehends a wall, ceiling or other like structure. Where the membrane serves as a ceiling such as in a corridor or stairwell, the studs 11 can serve as joists.
- the studs 11 can be used in vertical and horizontal orientations to frame a fire resistant chase or other structure.
- the membrane 10 is ordinarily assembled by locating the studs 11 , in conventional upper and lower U-shaped tracks (not shown) if it is to be a wall, in parallel relation on 2 ft. centers, for example.
- FIGS. 5A , 5 B, and 5 C illustrate optional conventional ways of bracing the studs 11 using a bridging member between adjacent studs 11 .
- FIGS. 5A and 5B illustrate an elongated channel 16 fixed with screws 17 to successive studs.
- FIG. 5A utilizes small clip angles 18 attached to aligned holes 19 in the webs of the studs 11 .
- a channel 16 is screw-attached to a flange of each stud 11 .
- a flat strap 22 is screw-attached to the stud flanges.
- a short section of track 23 known in the industry, shown in FIGS. 5B , 5 C, is boxed in and screw-attached to a pair of adjacent studs 11 .
- a similar track section 23 can be used at the ends of a wall and on, for example, 8 ft. centers. It will be appreciated that screw fasteners 17 used with the channels 16 or strap 22 and the track 23 can be driven by a person on a side of the studs 11 away from the channel or strap.
- the studs 11 are covered with a first layer 24 of the fire rated drywall.
- the layer 24 is attached to the studs 11 with conventional self-drilling drywall screws driven through the wallboard into the sides or flanges of the studs.
- elongated sheet metal channels 26 preferably of a type called a resilient channel and illustrated in FIG. 4 , are installed over the first layer 24 .
- the channels 26 are oriented horizontally so that they are perpendicular or cross wise relative to the stud 11 .
- the channels 26 are typically installed on 2 ft. centers. As illustrated in FIG. 4 , a channel 26 has a web 27 and opposed divergent sides 28 , 29 .
- One of the sides 28 is relatively wide and, preferably, has oblong apertures 31 spaced along its full length.
- the longitudinal edge of the apertured side 28 distal from the web 27 has an associated flange 32 oriented in a plane parallel to the web 27 .
- the shorter channel side 29 is spaced from the plane of the flange.
- the channels 26 are fastened to the studs 11 by drywall screws 33 driven through the flanges 32 and wallboard 11 into the sides of the studs.
- a second layer 34 of wallboard 12 is installed over the resilient channels. Drywall screws 36 fastening the wallboard 12 to the channels 26 are driven into the web 27 of the channel preferably at locations remote from the studs 11 . The length of the screws 36 is adequate to penetrate and hold onto the channel web 27 but insufficient to fully penetrate the first wallboard layer 24 .
- the described membrane construction 10 affords many benefits towards a high fire rating and greater utility over prior art arrangements. Since none of the screws retaining the layers 24 and 34 penetrate the full thickness of the membrane 10 , there is no direct heat conducting path from one side of the membrane to the other and which would create a hot spot to initiate a fire in a combustible.
- the channels 26 being fixed in cross relation to the studs 11 , serve to brace the studs against buckling forces. This function allows the ends of the studs to be assembled tight against the ends of other studs or tight within runner tracks (top and bottom) without gaps for thermal expansion and thereby increase the limiting height.
- the air space, designated 39 , between the wallboards 12 of the layers 24 and 34 serves as an insulator to reduce heat transfer from one board to the other.
- the perforations 31 in the channel side 28 allow air circulation over and through the channels 26 and reduce direct heat transfer through the channel side 28 from one wallboard to the other.
- the illustrated membrane 10 can be supplemented in its fire rating.
- another series of channels 26 can be mounted on the second layer 34 in the same manner as the illustrated channel 26 and a third fire rated wallboard can be fixed to this second series of channels 26 .
- the length of the screws be selected so as to not penetrate the full thickness of the membrane.
- a third layer of fire rated wallboard can be simply applied directly against the second layer 34 . In these and other construction variants, it is important that none of the screws extend through the exposed surfaces of wallboard on both sides of the membrane.
