Description
INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS

Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference and made a part of the present disclosure.


BACKGROUND
Field

The disclosure generally relates to fire-rated building structures. In particular, the disclosure relates to fire-rated joint systems, wall assemblies, and other building structures that incorporate the fire-rated joint systems.


Certain Related Art

Fire-rated construction components and assemblies are commonly used in the construction industry. These components and assemblies are aimed at inhibiting or preventing fire, heat, or 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 openings. The fire-rated components often incorporate fire-retardant materials which substantially block the path of the fire, heat or smoke for at least some period of time. Intumescent materials work well for this purpose, because they swell and char when exposed to flames helping to create a barrier to the fire, heat, and/or smoke.


One particular wall joint with a high potential for allowing fire, heat or smoke to pass from one room to another is the joint between the top of a wall and the ceiling, which can be referred to as a head-of-wall joint. In modern multi-story or multi-level buildings, the head-of-wall joint is often a dynamic joint in which relative movement between the ceiling and the wall is permitted. This relative movement is configured to accommodate deflection in the building due to loading of the ceiling or seismic forces. The conventional method for creating a fire-rated head-of-wall joint is to stuff a fire-resistant mineral wool material into the head-of-wall joint and then spray an elastomeric material over the joint to retain the mineral wool in place. This conventional construction of a fire-rated head-of-wall joint is time-consuming, expensive and has other disadvantages.


A wall assembly commonly used in the construction industry includes a header track, bottom track, a plurality of wall studs and a plurality of wall board members, possibly among other components. A typical header track resembles a generally U-shaped (or some other similarly shaped) elongated channel capable of receiving or covering the ends of wall studs and holding the wall studs in place. The header track also permits the wall assembly to be coupled to an upper horizontal support structure, such as a ceiling or floor of a higher level floor of a multi-level building.


Header tracks generally have a web and a pair of flanges, which extend in the same direction from opposing edges of the web. The header track can be a slotted header track, which includes a plurality of slots spaced along the length of the track and extending in a vertical direction. When the wall studs are placed into the slotted track, each of the plurality of slots aligned with a wall stud accommodates a fastener used to connect the wall stud to the slotted track. The slots allow the wall studs to move generally orthogonally relative to the track, creating a variable deflection gap between the wallboard and the upper horizontal support structure. In those areas of the world where earthquakes are common, movement of the wall studs is important. 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. With the plurality of slots, the wall studs are free to move. Even in locations in which earthquakes are not common, movement between the studs and the header track can be desirable to accommodate movement of the building structure due to other loads, such as stationary or moving overhead loads.


Recently, improvements to fire-rated head-of-wall joints have been developed. One example is the use a metal profile having a layer of intumescent material in a head-of-wall joint, such as the fire-rated angle manufactured and sold by the Applicant under the trade name Deflection Drift Angle (DDA™). The DDA™ angle is further described in U.S. Pat. No. 8,595,999, the entirety of which is hereby incorporated by reference. The DDA™ angle can be installed along with the installation of the header track or can be installed after the installation of the header track. Such an arrangement avoids the need to have the framers return after the installation of the wall board to install fire sealant in the deflection gap between the edge of the wall board and the overhead structure. When temperatures rise (e.g., due to a fire), the intumescent material on the DDA™ fire block product expands. This expansion creates a barrier which fills the deflection gap and inhibits or at least substantially prevents fire, heat, and smoke from moving through the head-of-wall joint and entering an adjacent room for at least some period of time.


SUMMARY

Although the DDA™ fire block represents an improvement over the conventional method of stuffing mineral wool material into the head-of-wall joint and applying the elastomeric spray material over the mineral wool, there still exists room for improved or alternative products, materials, and methods for efficiently and cost-effectively creating fire-rated wall joints.

DETAILED DESCRIPTION

The various features and advantages of the systems, devices, and methods of the technology described herein will become more fully apparent from the following description of the embodiments illustrated in the figures. These embodiments are intended to illustrate the principles of this disclosure, and this disclosure should not be limited to merely the illustrated examples. The features of the illustrated embodiments can be modified, combined, removed, and/or substituted as will be apparent to those of ordinary skill in the art upon consideration of the principles disclosed herein.


The following disclosure provides an elongate, fire-rated joint component or fire-blocking assembly, which is configured to provide fire protection and pass the relevant UL fire rating tests, or other relevant fire rating tests or standards. The fire-rated assembly may be installed in a deflection gap of a wall assembly that allows dynamic movement according to the requirements of UL-2079.


In one embodiment, the two piece fire-rated assembly can include one piece made of steel and one piece made of vinyl. One reason for this is that steel, generally, will not melt in a fire and will provide a continuous level of fire protection to the deflection joint. However, the steel profile by itself may not provide enough fire protection to pass a UL-2079 5th edition fire test and/or it may not provide adequate sound protection to the deflection gap. The second piece made from vinyl. The vinyl profile slides over the steel profile and locks them together so that the two can be assembled and installed as one piece.


The vinyl profile functions to provide sound protection. Unlike steel, the vinyl profile is very flexible and when the vinyl profile meets the overhead structure it can compress and seal off against uneven overhead structures to improve sound protection.


During a fire, a portion of the vinyl profile can flap downward and expose the intumescent material to the fire and heat which may cause the intumescent to expand upward and seal off the deflection gap. This whole process can take up to 20 minutes before the deflection is sealed off. During this time, the steel profile will remain in place over the leg of the header track and continue to offer a level of fire protection. Without the steel profile, the fire and heat would be able to pass through the deflection gap while the intumescent tape of vinyl profile was still expanding.



FIG. 1 illustrates an exploded view of the fire-rated profile assembly 10. The fire-rated profile assembly 10 is shown in cross-section. The fire-rated profile assembly 10 can be an elongate strip or gasket that can extend along the upper edge of a wall in a head-of-wall assembly as shown in cross-section in FIG. 3. The fire-rated profile assembly 10 can include a fire-rated angle 15 and a gasket profile 16. The fire-rated angle 15 and the gasket profile 16 can be formed in various lengths (e.g., 5 foot, 10 foot, 12 foot, or other), each preferably having the same cross-section and shape throughout. Assembled together, the fire-rated angle 15 and the gasket profile 16 can form the fire-rated profile assembly 10. The fire-rated profile assembly 10 can be installed across a head-of-wall assembly 100 to prevent the passage of smoke, heat, noise and/or other gases from passing through the head-of-wall assembly from one side of the wall to the other.


The fire-rated angle 15 can include an upper flange 19. The upper flange 19 can include one or more planar, curvilinear and/or stepped regions. The upper flange 19 can connect with a lower flange 21 at a corner 23. The lower flange 21 can include one or more planar, curvilinear and/or stepped regions. In the implementation shown in FIG. 1, the upper flange 19 is planar throughout and the lower flange 21 is planar throughout. The upper flange 19 can be perpendicular with the lower flange 21. Alternatively, the upper and lower flanges 19, 21 can be at an angle other than perpendicular. The lower flange 21 can extend from the corner 23 to a lower end 22. Optionally, the lower end 22 can comprise a plurality of through holes or apertures extending therethrough for assembly within the head-of-wall assembly.


The lower flange 21 can include a fire blocking strip 24. The fire blocking strip 24 can include an intumescent material that expands upon being heated. The fire blocking strip 24 can be attached by an adhesive with the lower flange 21. The fire blocking strip 24 can be attached on an interior side of the lower flange 27 (e.g., on the side of the upper flange 19 relative to the corner 23). The fire blocking strip 24 can be located adjacent to and/or in contact with the upper flange 19. The fire blocking strip 24 can extend along the interior surface of the lower flange 21 between the corner 23 and the lower end 22. Optionally, the fire blocking strip 24 can extend all the way from the corner 23 or the upper flange 19 to the lower end 22.


The fire-rated angle 15 can comprise a steel or other metal material. The steel can be generally resistant to deformation when exposed to heat or fire for at least a limited amount of time. The steel material can facilitate the fire-rated profile assembly 10 retaining its shape at least partially or temporarily when exposed to heat or fire.


The gasket profile 16 can include an upper flange 25. The upper flange 25 can include one or more planar, curvilinear and/or stepped regions. The upper flange 25 can include a flare out for forming a corner 29. The corner 29 can be form a compressible seal. The gasket profile 16 can include a lower flange 27. The lower flange 27 can include one or more planar, curvilinear and/or stepped regions. The lower flange 27 can connect with the upper flange 25 at the corner 29. The lower flange 27 can extend from the corner 29 to a hem or hook portion 37.


The lower flange 27 can include an upper section 31. The upper section 31 can be planar. The lower flange 27 can include a lower section 33. The lower section 33 can be an offset leg. The lower section 33 can be planar. The lower section 33 can attach with the upper section 31 through a transition section 35. The transition section 35 can offset the planar portions of the upper section 31 from the lower section 33. The direction of offset of the transition 35 can be in the same direction of the upper flange 25 extending from the corner 29. The offset of the transition can be the same width as a common framing screw. This will help maintain a tight seal when a drywall or wallboard is installed over the lower section 33. It will also allow the fire rated assembly 10 to be pre-attached to a header track, as described further below.


The lower section 33 can include the hook portion 37. The hook portion 37 can include a portion of the lower flange 27 that is bent backwards on itself to extend generally upwardly. The hook portion 37 can form a slot. The slot can be sized to receive the lower end 22 of the fire-rated angle 15.


The lower flange 27 can include a fire blocking strip 34. The fire blocking strip 34 can be adhesively attached with the lower flange 27. The fire blocking strip 34 can be attached on an interior side of the lower flange 27. The fire blocking strip 34 can be attached with the upper section 31. The fire blocking strip 34 can be adjacent to the corner 29 and/or the upper flange 25. The fire blocking strip 34 can extend from the corner 29 towards the transition 35. An outer surface of the fire blocking strip 34 can be aligned with the lower section 33, as shown by the dotted line in FIG. 1. The transition section 35 can be sized to offset the lower section 33 from the upper section 31 by the thickness of the fire blocking strip 34.


The gasket profile 16 can be formed of a vinyl or other polymer material. The material of the gasket profile 16 can be sensitive to heat such that it deforms when heated at temperatures associated with fires.



FIG. 2 shows the fire-rated angle 15 assembled with the gasket profile 16 to form the fire-rated profile assembly 10. The lower end 22 can be assembled within the slot of the hook portion 37. The lower flange 21 can be assembled against the lower section 33 and/or the fire blocking strip 34. The upper flange 19 can be assembled in contact with the upper flange 25. The corner 23 can be offset from the corner 29 by the flare out of the upper flange 25. The fire blocking strip 24 can be aligned with or partially offset with the fire blocking strip 34. A length of the lower flange 21 can be sized such that the upper flange 19 contacts the upper flange 25 with the lower end 22 assembled within the slot of the hook portion 37.



FIG. 3 shows the fire-rated profile assembly 10 installed within a head-of-wall assembly 100. The head-of-wall assembly can include a ceiling or overhead structure 120. A header track 130 can be attached with the overhead structure 120. The header track 130 can include a web 136, a first flange 132 extending from the web 136 and a second flange 134 extending from the web 136. The first flange 132 and the second flange 134 can extend generally perpendicular to and on opposite sides of the web 136. A stud 140 can be received between the first flange 132 and the second flange 134. A wall board 150 can be attached with the stud 140. The upper end of the wall board 150 can form a deflection gap between the overhead structure and the wall board 150. The deflection gap 160 can be variable as the stud 140 and the wall board 150 move relative to the overhead structure 120.


The fire-rated profile assembly 10 can be assembled within the deflection gap 160. The upper flanges 19, 25 can be installed between the web 136 and the overhead structure 120. The lower flanges 21, 27 can be installed along the length of the second flange 134. The lower flanges 21, 27 can be installed between the second flange 134 and the wall board 150. The fire blocking strip 24 can be in contact with the second flange 134. The upper section 31 can be in slidable contact with an inner face of the wall board 150, as the wall board 150 cycles between open and closed configurations of the head-of-wall assembly 100. The corner 29 can be compressed against the overhead structure 120 to form a seal therewith.


The fire-rated profile assembly 10 can be maintained within the deflection gap 160 through mechanical engagement between the overhead structure 120 and the web 136. The wall board 150 installed over the lower flanges 21, 27 can also maintain the position of the fire-rated profile assembly 10 within the deflection gap 160. Advantageously, this arrangement can be faster and easier to install than using mechanical fasteners or traditional stuff-and-spray techniques. FIG. 4 shows the head-of-wall assembly 100 with the deflection gap 160 in a closed configuration with the wall board 150 slid over the lower flange 27.



FIG. 5 shows the results of fire or heat on the head-of-wall assembly 100 with the fire-rated profile assembly 10 installed within the deflection gap 160. The heat can cause the material of the gasket profile 16 to soften and fold outwardly across the top portion of the wall board 150. Once the portion of the gasket profile bends down the fire-blocking strip 34 faces the overhead structure 120. This can be ideal for expansion of the intumescent because it will expand upward against the overhead structure 120 and seal off the deflection gap 160. The fire-rated angle 15 can remain in place to offer some fire protection while the intumescent is expanding. The fire-rated angle 15 can remain in place being formed of a metal or steel material. The fire blocking strip 34 can expand upwardly towards the overhead structure 120. The upper flange 25 can at least partially contain the expanding intumescent material of the fire blocking strip 34. This can prevent the fire blocking strip 4 from falling out of the deflection gap 160 prematurely. The fire blocking strip 24 can also expand to provide additional blockage across the deflection gap 160.



FIG. 6 shows the fire-rated profile assembly 10 preinstalled on the header track 130. A fastener 170 can be installed through the lower section 33 of the gasket profile 16. The fastener 170 can be inserted through a hole formed in the lower end 22 of the fire-rated angle 15 and/or the lower flange 27 of the gasket profile 16. The fastener 170 can be installed through the second flange 134 of the header track 130. The fastener 170 can be offset from any of the studs of the head-of-wall assembly 100 (e.g., into and out of the page as shown in FIG. 6).


Advantageously, the fire-rated profile assembly 10 can be pre-installed on the header track 130. The header track 130 can then be assembled against the overhead structure 120 such as through additional mechanical fasteners through the web 136. The pre-installation can dramatically reduce the amount of time required for attaching the fire-rated profile assembly 10 within the head-of-wall assembly 100. It can be much easier to pre-install the fire-rated profile assembly 10 than inserting the upper flanges 19, 25 between the overhead structure 120 and the web 136. The transition section 135 can be sized to accommodate the head of the fastener 170 so that the wall board 150 can be engaged with the upper section 131 and/or the head of the fastener 170.



FIG. 7 shows another embodiment of a fire-rated assembly 200. The fire-rated assembly 200 can be a two-piece fire-rated assembly including a vinyl or other polymer member and a steel or other metallic member. The fire-rated assembly 200 can include a gasket profile 216. The gasket profile 216 can include an upper flange 225. The upper flange 225 can include one or more planar, curvilinear, or stepped sections. The upper flange 225 can include a downward extending flange 226. The downward extending flange 226 can include a flat region that is generally vertical.


The upper flange 225 can include or be coupled to a corner 229. The corner 229 can be a curved or bent section of the material of the gasket profile 216. A lower flange 227 can extend from the corner 229. The lower flange 227 can include an upper section 231 and a lower section 233. The upper section 231 can include straight, curvilinear or stepped regions. The upper section 231 can be coupled to the lower section 233 by a transition section 235. The transition section 235 can be orthogonal to the flat portion or straight portion of the upper section 231. The lower section 233 can include straight, curvilinear or stepped regions. The lower section 233 can couple on an upper end with the transition section 235. The lower section 233 and/or the upper section 231 can include a planar section that is perpendicular to the transition section 235.


The lower section 233 can include a kick out 237. The kick out 237 can comprise a planar section that is at an angle with respect to a planar section of the lower section 233. The kick out 237 can be angled towards an exterior side of the gasket profile 216 (e.g., opposite the extension of the upper flange 225).


The transition section 235 can include an inner flange 236. The inner flange 236 can extend from an upper end of the lower section 233. The inner flange 236 can at least partially form an interior region of the gasket profile 216 between the upper section 231 and the inner flange 236. The upper section 231 can include a fire blocking strip 234. The fire blocking strip 234 can be located between the corner 229 and the transition section 235 along the upper section 231. The fire blocking strip 234 can be located within the interior section of the gasket profile 216.


The fire-rated assembly 200 can further include a fire-rated insert 215. The fire-rated insert 215 can comprise a steel plate. The steel plate can include planar, straight, curvilinear, or stepped regions. The insert 215 can include a straight section 221. The straight section 221 can extend between an upper end 223 and a lower end 222. The upper end 223 can include a fire blocking strip 224. The fire blocking strip 224 can extend between the upper end 223 and the lower end 222.


As illustrated in FIG. 8, in an assembled configuration the fire-rated insert 215 can be installed within the interior section of the gasket profile 216 (e.g., formed by the inner flange 236, the upper flange 225, and/or the upper section 231). . The upper end 223 can be installed within a slot formed by the downwardly extending flange 226. The lower end 222 can be installed within a slot formed by the inner flange 236. The fire-rated insert 215 can be installed within the interior of the gasket profile 216 by elastically deforming the material of the gasket profile 216 (or sliding at one end of the gasket profile 216). In the assembled configuration, the straight section 221 can contact the fire blocking strip 234. The fire blocking strip 224 can contact the downwardly extending flange 226 and/or the corner 229.


A head-of-wall assembly 300 can include an overhead structure 320, a header track 330 attached with the overhead surface 320. The header track 330 can include a first flange 332, a second flange 334, and a web 336. A stud 340 can be assembled between the first flange 332 and the second flange 334 and coupled therewith by a first mechanical fastener 374. A wall board 350 can be attached with the stud 340. A deflection gap 360 can be formed between the upper end of the wall board 350 and the overhead structure 320. The stud 340 and the wallboard 350 can be movable vertically to open and close the deflection gap 360.


The fire-rated assembly 200 can be installed alongside of the second flange 334 within the deflection gap 360. A second mechanical fastener 372 can be installed through the lower section 233 of the lower flange 227. The second fastener 372 can attach the assembly 200 with the second flange 334. In certain implementations, the fire-rated assembly 200 can be preinstalled on the header track 330. The corner 229 can be compressed against the overhead structure 320 to form a seal therewith. The interior side of the fire-rated assembly 200 can face the second flange 334. The downwardly extending flange 226, the lower section 233, and/or the inner flange 236 can be flush against the second flange 334. The insert 215 can be located within the interior portion of the gasket profile 216 facing the second flange 334.


The first fastener 374 can be offset from the second fastener 372 (e.g., into and out of the page as shown in FIG. 9A). In other words, the fire-rated assembly 200 can be attached at locations along the header track 330 that are not in axial alignment (into and out of the page) with the second fastener 372 or the stud 340. The first fastener 374 can be movable within a slot 334a, as shown in FIGS. 9C (closed configuration) and 9D (open configuration), as the deflection gap 360 cycles between open and closed configurations. Accordingly, as the deflection gap moves between the open and closed configurations, the head of the first fastener 374 can move underneath the lower section 233 of the lower flange 227. The flexible material of the gasket profile 216 can allow passage of the first fastener 374. The vinyl material is flexible so that, even though the gasket profile is attached to the second flange 334 of the track 330 with the second fastener 372 (e.g. framing screw) the first fastener 374 (e.g., framing screw) that attaches the stud 340 to the track 330 will still be able to cycle under the gasket profile flange 227, as shown. This sliding can be facilitated by the kick out 237. Optionally, the inner flange 236 can include a kick out, like the kick out 237.


When the fire-rated assembly 200 is exposed to heat or fire, the fire blocking strips 224 and/or 234 can expand to fill the deflection gap 360, the formable material of the gasket profile 216 can be at least partially maintained in its position by the insert 215. The insert 215 along with the upper section 231 and the upper flange 225 can fold outwardly across the top of the wall board 350 when exposed to heat or fire. The insert 215 can maintain structural integrity of the upper section 231 and thereby direct the expansion of the fire blocking strips 224, 234 towards the overhead structure 320 to close the deflection gap 360.



FIG. 10 illustrates an exploded cross-sectional view of another embodiment of a fire-rated profile assembly 410 configured to seal a construction gap, such as a deflection gap at a head-of-wall condition. In some embodiments, the fire-rated profile assembly 410 can include an elongate strip or gasket that can extend along the upper edge of a wall in a head-of-wall assembly as illustrated in FIG. 12 and discussed further below.


The fire-rated profile assembly 410 can include a first portion in the form of a fire-rated insert 415 and a second portion in form of a gasket profile 416. The fire-rated insert 415 and the gasket profile 416 can be formed in various lengths (e.g., 5-foot, 10-foot, 12-foot, or other lengths smaller than 5 feet or larger than 10 feet). The fire-rated insert 415 and the gasket profile 416 can be formed to include a length that is generally the same or similar as one another. Each of the fire-rated insert 415 and the gasket profile 416 preferably has the same cross-section and shape throughout. Assembled together, the fire-rated insert 415 and the gasket profile 416 can form the fire-rated profile assembly 410. In some embodiments, the fire-rated profile assembly 410 can be installed along a head-of-wall assembly 500 (as illustrated in FIGS. 12 and 13A-13C) to inhibit or prevent the passage of smoke, heat, noise and/or other gases from passing through the head-of-wall assembly from one side of the wall to the other.


The fire-rated insert 415 can include an elongate first body portion 421. The first body portion 421 can be or include metal, steel, vinyl, or other similar materials. The steel or other materials can be generally resistant to deformation when exposed to heat or fire for at least a limited amount of time. The steel or other materials can facilitate the fire-rated profile assembly 410 in at least partially retaining its shape at least temporarily when exposed to heat or fire. The first body portion 421 can have a lower end 422 and an upper end 419. The lower end 422 can include a round or flat surface. The lower end 422 can be flexible. The upper end 419 can include a round or flat surface. Similarly, the upper end 419 can be flexible. For example, in some embodiments, the lower end 422 and/or the upper end 419 can flex or bend relative to one another or to a central portion of the first body portion 421. In some embodiments, the upper end 419 can include an offset to aid the fire-rated insert 415 to be secured in the upper portion of the gasket profile 416.


The fire-rated insert 415 can include a first fire-blocking strip 424 coupled to the first body portion 421. The first fire-blocking strip 424 can include an intumescent material that expands in response to heat. The first fire-blocking strip 424 can be connected to the first body portion 421 by adhesive or other types of fasteners. In some embodiments, the first fire-blocking strip 424 can be an intumescent tape. In some embodiments, the first fire-blocking strip 424 can be located approximately in the middle of the first body portion 421 such that the distance from the center of the first fire-blocking strip 424 to the upper end 419 is the same as or approximately similar to the distance from the center of the first fire-blocking strip 424 to the lower end 422. In some embodiments, the first fire-blocking strip 424 can be positioned closer to the upper end 419 or the lower end 422. The first fire-blocking strip 424 can extend along a central or intermediate portion of the interior surface of the first body portion 421 between the upper end 419 and the lower end 422. In some embodiments, the first fire-blocking strip 424 can extend all the way from the upper end 419 to the lower end 422. In some embodiments, the fire-rated insert 415 can include an attachment piece (such as a double-sided tape) positioned above or below the fire-blocking strip 424.


The gasket profile 416 can include a second body portion 431. The second body portion 431 can be planar or include a planar portion. In some embodiments, the second body portion 431 can be or include vinyl or another polymer material. The material of the gasket profile 416, including the material of the second body portion 431, can be sensitive to heat such that it deforms when heated at temperatures associated with a fire event.


The second body portion 431 of the gasket profile 416 can include an upper portion 425. The upper portion 425 can include one or more round, planar, curvilinear and/or stepped regions. The upper portion 425 can include an upper hook portion 429. The upper hook portion 429 can create an upper cavity 426. In some embodiments, the upper hook portion 429 can include a segment of the upper portion 425 that is bent on itself to extend generally downwardly. In some embodiments, the upper hook portion 429 can include an offset which can extend towards the second body portion 431 to aid secure the fire-rated insert 415 in the gasket profile 416. The upper portion 425 can include an attachment strip such as attachment piece 428. The attachment piece 428 can include an adhesive or other types of mechanisms that can facilitate the attachment of the gasket profile 416 to a building structure. In some embodiments, the attachment piece 428 can be a double-sided tape such that the attachment piece 428 is connected to the upper portion 425 on one side and allows the attachment of the gasket profile 416 to a building structure on the other side. In some embodiments, the attachment piece 428 can be an attachment strip and/or a tape.


The second body portion 431 of the gasket profile 416 can include a lower portion 427. The lower portion 427 can include one or more round, planar, curvilinear and/or stepped regions. The lower portion 427 can include a lower hook portion 437, such as a hem, that can create a lower cavity 440. In some embodiments, the lower hook portion 437 can include a segment of the lower portion 427 that is bent backwards on itself to extend generally upwardly. The lower cavity 440 can be sized to receive the lower end 422 of the fire-rated insert 415.


The second body portion 431 can include an upper fire-blocking strip 434 and a lower fire-blocking strip 435. The upper fire-blocking strip 434 and the lower fire-blocking strip 435 can be positioned on the second body portion 431 between the upper portion 425 and the lower portion 427. The upper fire-blocking strip 434 and the lower fire-blocking strip 435 can be adhesively attached on the interior side of the second body portion 431. The upper fire-blocking strip 434 and the lower fire-blocking strip 435 can be attached with the second body portion 431 using adhesive or other types of fasteners. The upper fire-blocking strip 434 and the lower fire-blocking strip 435 can include an intumescent material that is adhesively connected to the second body portion 431. For example, the upper fire-blocking strip 434 and the lower fire-blocking strip 435 can be an intumescent tape.


The upper fire-blocking strip 434 and the lower fire-blocking strip 435 can be separated by a separation 436. As discussed further with respect to FIGS. 13A-13C, the separation 436 can contribute to the performance of the fire-rated profile assembly 410 during a fire event. In some embodiments, the combined widths of the fire blocking strips (such as the first fire-blocking strip 424, the upper fire-blocking strip 434, and the lower fire-blocking strip 435) can be at least about half of the maximum width of a deflection gap (such as the deflection gap 560 discussed below with respect to FIG. 12) that the fire-rated profile assembly 410 is intended to cover or seal. For example, the overall width of the first fire-blocking strip 424, the upper fire-blocking strip 434, and the lower fire-blocking strip 435, when combined together, can be about 2 inches to cover a deflection gap of having a maximum width of about 4 inches. As discussed here, the width direction can refer to a direction aligned with a vertical direction of an in-use orientation of a flange of a header track while a length direction can refer to a direction along the length of the in-use orientation of the flange of the header track.



FIG. 11A and FIG. 11B illustrate the fire-rated insert 415 assembled with the gasket profile 416 to form the fire-rated profile assembly 410. The lower end 422 can be positioned within the lower cavity 440 of the lower hook portion 437. The first body portion 421 can be positioned against the upper fire-blocking strip 434 and lower fire blocking strip 435. The upper end 419 can be positioned within the upper cavity 426 of the upper hook portion 429. The first fire-blocking strip 424 can be aligned with or be positioned against the separation 436 (See FIG. 10). In some embodiments, the first body portion 421 can be sized such that the upper end 419 contacts the upper portion 425 with the lower end 422 positioned within the lower cavity 440 of the lower hook portion 437. In some other embodiments, the upper end 419 or the lower end 422 do not directly contact the corresponding surface in the gasket profile 416. In some embodiments, as it can be seen in FIG. 11B, the fire-rated profile assembly 410 can include an optional fastener 438. The fastener 438 can secure the fire-rated insert 415 to the gasket profile 416. For example, the fastener 438 can connect the lower portion 427 or the second body portion 431 of the gasket profile 416 to the lower end 422 or the first body portion 421 of the fire-rated insert 415. In some embodiments, the fastener 438 can be configured to penetrate the gasket profile 416, fire-rated insert 415, and connect the fire-rated profile assembly 410 to a building structure, such as a header track (e.g., header track 530FIG. 12).



FIG. 12 illustrates the fire-rated profile assembly 410 in use in a head-of-wall assembly 500 to cover or seal a deflection gap 560 between a wallboard 550 and an overhead structure 520. The fire-rated profile assembly 410 can be configured to cover gaps of various sizes. In some embodiments, the deflection gap 560 can be up to 4 inches or more between the top of the wallboard 550 and the overhead structure 520. In some embodiments, the overall width of the fire-rated profile assembly 410 is at least about 0.5 inch greater than a maximum width of the deflection gap 560. For example, the overall width of the fire-rated profile assembly 410 can be at least about 4.5 inches to cover an approximately 4-inch deflection gap 560.


The head-of-wall assembly 500 can include a wall gap 545, which in some cases can be created as result of the protrusion that can be present on the head of fastener(s) that are used to secure studs 540 to a header track 530. The fire-rated profile assembly 410 can be positioned so that a lower portion of the fire-rated profile assembly 410 is positioned within the wall gap 545 between a wallboard 550 and a building element, such as the header track 530 or the wall stud 540. The wall gap 545 illustrated in FIG. 12 (and FIGS. 13A through 13C discussed below) may be exaggerated for clarity. In some embodiments, the wallboard 550 can be in contact with the fire-rated profile assembly 410. The header track 530 can include a first flange 532, a web 536, and a second flange 534. The attachment piece 428 can facilitate the connection of the fire-rated profile assembly 410 to the second flange 534 of the header track 530. In some embodiments, the attachment piece 428 is coupled to the upper portion 425 such that the upper end of the attachment piece 428 extends past the upper end of the upper portion 425. This arrangement can ensure that the attachment piece 428 contacts a lower surface 535 of the overhead structure 520 when the fire-rated profile assembly 410 is in use even if the lower surface 535 is uneven or not flat.



FIGS. 13A through 13C illustrate the fire-rated profile assembly 410 in the head-of-wall assembly 500 at different stages of expansion of the fire blocking strips related to different stages of, or time of exposure to, an elevated heat or fire. For example, in FIG. 13A, the fire-rated profile assembly 410 can be seen at the initial stage of fire or expansion, for example, within approximately the first 30 minutes of exposing the fire-rated profile assembly 410 to heat or fire.



FIG. 13B illustrates the fire-rated profile assembly 410 at the second stage of fire or expansion, for example within about 1 hour after the fire-rated profile assembly 410 is exposed to heat or fire. As it can be seen in FIG. 13B, the fire-rated profile assembly 410 has started to move away from the header track 530 and the intumescent materials of the first fire-blocking strip 424, the upper fire-blocking strip 434 and the lower fire-blocking strip 435 have started to expand in response to heat or fire. At this stage, the fire-rated profile assembly 410 is configured to resist movement on top as it is connected to the header track 530 through the attachment piece 428. Similarly, at the bottom, the fire-rated profile assembly 410 is pinched in the wall gap 545 between the wallboard 550 and the header track 530. The fire-rated profile assembly 410 can resist movement as it is positioned within a space surrounded by the upper portion 425 and the lower portion 427. This arrangement facilitates the expansion of the fire-rated insert 415 away from the header track 530 at the middle section while maintaining its approximate position at the top and bottom sections. This arrangement ultimately causes the fire-rated insert to break into two sections at approximately around the middle section of the fire-rated insert 415.



FIG. 13C illustrates the fire-rated profile assembly 410 at a third stage of fire or expansion, for example, after the fire-rated profile assembly 410 has been exposed to fire or elevated heat for about 2 hours. As illustrated, the intumescent material has continued to expand primarily in a direction that is in a thickness direction of the intumescent material such that the upper fire-blocking strip 434 and the lower fire-blocking strip 435 expand towards each other in a substantially or primarily vertical direction. At this stage, the bottom section of the fire-rated profile assembly 410 is supported by the wallboard 550 and the top section of the fire-rated profile assembly 410 expands away from the header track at least because of the expansion force created by expansion of the intumescent material. This arrangement illustrates that at the final stage of fire, the fire-rated profile assembly 410 forms a barrier in the deflection gap 560 that can inhibit or prevent a passage of heat or fire.
