Abstract
A fire resistant assembly which may be used to ensure the fire resistance of a fire barrier such as a wall, comprising a first layer having a lumen therein, a second layer adjacent the first layer, and a box having a cavity defined by a wall, an opening in the wall, and a flange proximate the opening, wherein the box is disposed between the first layer and the second layer and wherein the opening is disposed on the lumen of the first layer.
Description
- The present application is a continuation application of U.S. patent application Ser. No. 10/199,565, filed Jul. 19, 2002, the complete disclosure of which is herein incorporated by reference.
- The invention relates to a fire barrier having a recess for a device. More particularly, the invention relates to a recessed box installed in a building for use with maintaining a minimum fire endurance of a building surface.
- Typically, a surface of a building such as a floor or a ceiling provides a fire barrier. A fire barrier resists the spread of a fire through it by providing a resistance to flammability, a resistance to heat transmission, and sufficient structural integrity to resist decomposing when exposed to heat or flames. The effectiveness of a fire barrier is often rated by exposure to a fire of specified and increasing intensity and a rating is a period of time, typically in hours during which the fire barrier is effective. When an aperture is made in one of these fire barriers, the effectiveness of the fire barrier is decreased dramatically. Often it is nonetheless desirable to create an aperture in a fire barrier, for example, to install recessed lighting or a floor drain. To restore the fire barrier and maintain an effective minimum resistance to fire, a construction worker will typically build a box of gypsum board and install it around the recessed fixture proximate the aperture created in the fire barrier. The construction of this box is a time consuming task and provides no mechanism to ascertain to what degree the effectiveness of the fire barrier is restored.
- The present invention pertains to a prefabricated box suitable for use with a wide variety of recessed devices. The prefabricated box may be easily installed and may provide a known degree of fire endurance.
- An embodiment of the invention pertains to a fire barrier. A box, comprising a cavity defining a wall, a opening in the wall, and a flange proximate the opening, may be disposed between a first and a second layer, the opening of the box covering a lumen of the first layer. The box may be attached to a first and a second structural member. A device may be disposed in the lumen of the first layer and extend into the cavity of the box. There may be a gap between the device and the wall of the box and between the wall of the box and the second layer. The box may comprise steel or other suitable material and the wall of the box may be impervious to the passage of air. The fire barrier may be rated for 1 hour or greater fire endurance rating under ASTM E-119 or other comparable test and certification of the rating may be found with or on the box.

FIG. 1 is a perspective view ofbox 100 for providing fire resistance according to the invention; and -
FIG. 2 is a cross sectional view ofbox 100 positioned inside a fire barrier. - Reference is now made to the figures, in which like element numbers refer to like elements throughout.
FIG. 1 is a perspective view ofbox 100, which includescavity 102 defining awall 104.Opening 106 provides access tocavity 102 andflange 108 is disposedproximate opening 106. It is to be understood that, whilewall 104 is shown inFIG. 1 to be comprised of five flat surfaces and the opening, any shape defined by a cavity and having an opening may be suitable. For example, a cylinder open at one end may be suitable. -
Flange 108 may be comprised of one or moreindividual pieces 110 and generally defines a flat surface 112 facing away fromcavity 102.Flange 108 is shown as comprising a lip extending a uniform distance away from the edge of the opening. It is to be understood however, that many more configurations that may be suitable are contemplated. For example,flange 108 may have struts which extend over the opening to provide means for attaching a device such as a light fixture. In addition,flange 108 may have wings that extend from the opening to provide additional means for attaching the box in the fire barrier.Flange 108 may include means for attachingbox 100 to a structural member such aslumens 114 for receiving nails or screws. -
Wall 104 may include punch-outs 116 that permit ready removal with a hammer or screwdriver for created additional openings to the cavity. Punch-outs 116 generally comprises one or more grooves of reduced wall thickness formed in a closed pattern. Punch-outs 116 may be of several shapes and sizes to allow for the creation of additional openings adapted to specific tasks. -
FIG. 2 is a cross sectional view ofbox 100 disposed in afire barrier 200, which is fire resistant, and having a device 218 disposed therein. - The term “fire resistant” is herein defined to refer to the ability of a structure to serve as a barrier to the spread of fire. To serve as an effective barrier to the spread of fire, a structure must exhibit the following characteristics. First, it must not pass flame or hot gas from one side to the other. Second, the structure must support the imposed design loads without structural failure or collapse. Third, the structure must resist the transmission of heat so that the surface not exposed to the fire does not exceed the temperature of 250° F. Fourth, the structure must withstand lateral impacts from falling debris. This is definition of the term “fire resistant” as understood by those of skill in the art.
-
Fire barrier 200 is disposed in a building; suitable fire barriers may comprise a floor and a ceiling, a ceiling and a roof, or a wall and a wall. The fire barrier depicted inFIG. 2 comprises a ceiling and the floor above.Fire barrier 200 may be comprised of afirst layer 220 having a lumen 222 therein, asecond layer 224, andbox 100 disposed therebetween.Fire barrier 200 may also comprisestructural members 224, such as joists, to whichbox 100 may be fastened usingfasteners 226.Box 100 may also be fastened using other suitable means such as a high temperature epoxy or spot welding. - Lumen 222 generally has a
perimeter 228 which may be smaller than theperimeter 230 of opening 106.Layer 220, therefore, may extend overflange 108 andperimeter 230. Adevice 232 may be disposed in lumen 222 and extend intocavity 102. This device may be any device installed in a fire barrier. The device may be, for instance, an electrical device such as a light fixture or a fan, or it may be a different device, such as a floor drain. Ifdevice 232 is an electrical device, it may havewires 234 extending therefrom. A punch-out of the appropriate size may be removed, providing anopening 236 though whichwires 234 may extend. It may be desirable to provide anopening 236 that is not substantially larger than the cross section of the objects extending therethrough in order to maintain the integrity of the fire barrier. There may be agap 238 betweenwall 104 and layer 222 and there may also be agap 240 betweendevice 232 andwall 104. These gaps may enhance the fire resistance offire barrier 200. -
Layers 220 and 222 may comprise materials well known by those of skill in the art such as gypsum board, plywood, plaster, or tile.Box 100 may be comprised of steel or other material having a melting temperature, for example, above 1700° Fahrenheit such as ceramic. For example,box 100 may be comprised of 24-gauge stainless steel. This material may be galvanized to resist corrosion.Wall 100 may have aperimeter wall 242 that has an angle with the flange of greater than 90 degrees. This may facilitate stacking ofboxes 100. Ifbox 100 comprises joints, these joints should be sealed by welding or another suitable process to makewall 104 substantially impermeable to air flow. -
Fire barrier 200 should be capable of an ASTM E-119 fire resistance rating of at least 1 hour. A fire resistance rating of 1 hour exposes one side of the fire barrier to the following sequence of temperatures: 1000° F. for 5 minutes, 1400° F. for 15 minutes, 1550° F. for 30 minutes, and 1700° F. for 10 minutes. At no time during this test should the fire barrier permit flames or hot gases through to the unexposed surface or allow the unexposed surface to exceed 250° F. This test was designed to simulate the conditions a real fire might expose a fire barrier to. Of course, if this test is updated to reflect new understandings of the conditions of a fire, the fire barrier should be capable of a comparable rating under the new test. -
Fire barrier 200 may be rated under ASTM E-119 or a comparable test. The process of rating includes creating afire barrier 200 and subjecting it to the test. A ratedfire barrier 200 may permit installation ofbox 100 in fire barriers governed by regulations. Certification of the rating may be included withbox 100. Certification may also be affixed onbox 100, either on a label or permanently impressed intobox 100 by stamping, etching or some similar process. - Numerous advantages of the invention covered by this document have been set forth in the foregoing description. It will be understood, however, that this disclosure is, in many respects, only illustrative. Changes may be made in details, particularly in matters of shape, size, and arrangement of parts without exceeding the scope of the invention. The invention's scope is, of course, defined in the language in which the appended claims are expressed.
