Abstract
Description
- This invention concerns a fire seal, and particularly but not exclusively a fire seal selectively engageable between the side edge of a floor panel and a facing wall; and also a fire sealing assembly.
- It is often desirable or required to prevent the passage of fire between floor slabs, and side walls or external facades or rain screens. Conventionally this is generally achieved using intumescent materials. This generally involves a certain time delay to provide a seal as the material intumesces in the event of a fire, and such seals may not always be wholly reliable.
- According to a first aspect of the invention there is provided a fire seal, the fire seal including an elongate housing and an elongate sealing member, the elongate sealing member being selectively movable relative to the elongate housing between an inactive position located at least to a significant extent within the elongate housing, and an active position extending outwardly to a significant extent from the elongate housing, whereby a gap adjacent to the elongate housing can be closed, the elongate sealing member being urged to the active position, a fusible restraint being provided for retaining the elongate sealing member in the inactive position, the fusible restraint being configured to fail at a required raised temperature such that the elongate sealing member will automatically move to the active position, for instance in the event of a fire.
- The elongate housing may be in the form of a channel section, which channel section may have internal lips either side of the opening, so as to prevent the elongate sealing member from fully moving out of the elongate housing.
- The elongate housing may be made of any of steel, aluminium, or calcium silicate.
- The elongate sealing member may be in the form of a channel section with an opening facing towards the elongate housing. The elongate sealing member channel section may have an external lip engageable with the internal lip on the elongate housing so as to prevent the elongate sealing member from fully moving out of the elongate housing.
- The elongate sealing member may be made of any of steel, aluminium or calcium silicate.
- A resilient member may be provided engageable between the elongate housing and the elongate sealing member, to urge the elongate sealing member away from the elongate housing. The resilient member may locate within the elongate housing. The resilient member may comprise one or more compression springs.
- A sealing part may be provided on an outer face of the elongate sealing member. The sealing part may comprise any of a brush, vane seal, intumescent seal, or an elongate strip, which strip may be hollow and may be made of silicone or EPDM.
- The fusible restraint may comprise a link extendible between the elongate housing and elongate sealing member when in the active position. The fusible restraint may be made of nylon, EPDM, rubber, PVC or metal, and especially an alloy.
- Alternatively the fusible restraint may comprise a sleeve extending at least partially around the elongate housing and elongate sealing member so as to restrain the elongate sealing member in the inactive position. The sleeve may be made of PVC, or the sleeve may be made of a paper material.
- The fusible restraint may be configured to fail at a temperature of between 120 and 160°C.
- A plurality of resilient members may be provided.
- A guide may be provided, which is locatable inside the helical coil of one of the one or more compression springs, to maintain the alignment of the compression springs.
- The fire seal may further include an extension arrangement for spacing the elongate housing and the elongate sealing member from a mounting point such as a floor panel. The extension arrangement may include an elongate spacer for location between the elongate housing and a bracket, wherein the bracket is for mounting to a floor panel, the spacer is mountable to the bracket, and the housing is mountable to the spacer.
- The invention still further provides a fire sealing assembly, the assembly including a fire seal according to any of the preceding paragraphs provided on a side edge of a floor panel and facing towards a wall, with the fire seal configured such that in the inactive position a space is provided between the floor panel and the wall, but in the active position the sealing member engages against the wall to close the space.

Fig. 7 thefusible link 22 has been broken such that theelongate sealing member 16 extends out of theelongate housing 12, with the external lips on the sealing member engageable 18 with theinternal lips 14 on the housing member. - The fusible link may take a number of different forms, and four examples are shown respectively in
Figs. 8 - 11 .Figs. 8 and9 showfusible links Figs. 10 and 11 show metal alloyfusible links central part 38 which is intended to fail in the event of a fire. Thefusible links - A sealing part may be provided on the outer end of the sealing
member 16 to provide a good seal for instance against thewall 26. Four examples of sealing parts are shown inFigs. 12 to 19 . In the second sealingmember 38 inFigs. 12 and 13 , an elongate sealingpart 40 is provided which is essentially dome shaped and may be hollow. This may be made of silicone or EPDM. -
Figs. 14 and15 show athird sealing member 42 with anintumescent sealing part 44 in the form of a strip of intumescent material on the outer end of the sealingmember 16. -
Figs. 16 and 17 show afourth fire seal 46 where the sealingpart 48 is in the form of a brush seal. -
Figs. 18 and 19 show afifth fire seal 50 in which the sealing member is in the form of avane seal 52 mounted to a distal end of the compression spring 54. As can be seen thevane seal 52 is held in a spiral within theelongate housing 12 until it uncoils when afusible link 56 has been broken. -
Figs. 20 and21 show asixth fire seal 58. In this instance no lips are provided on theelongate housing 12 or elongate sealingmember 16, and thecompression spring 20 retains a link from thehousing 12 to the sealingmember 16 when in active position.Figs. 20 and21 illustrate another form of fusible link in the form of asleeve 60 which in this instance is made of PVC, that surrounds thehousing 12 and sealingmember 16, to retain sealingmember 16 in thehousing 12 an inactive position, until thesleeve 60 fails for instance in the event of a fire. -
Figs. 22 to 25 show aseventh fire seal 62 which is similar to thesixth fire seal 58, but includes a plurality of compression springs 20. In this example, theseventh fire seal 62 includes three compression springs 20 spaced along the length of thefire seal 62, to ensure a uniform transition along the length of the fire seal from an inactive to an active position. The compression springs 20 can be fastened to theelongate housing 12 and the elongate sealingmember 16 using fixingscrews 64 and/or rivets. The alignment of the compression springs 20 is maintained by one or more guides 66. The one ormore guides 66 may be in the form of rods which are locatable inside the helical coil of the compression springs 20 to maintain the alignment of the compression springs 20. -
Figs. 22 and24 show theseventh fire seal 62 in an inactive position. The sealingmember 16 is restrained in theelongate housing 12 an inactive position by a sleeve (not shown) extending partially around theelongate housing 12 and elongate sealingmember 16 between theelongate housing 12 and the sealingmember 16.

Thechannel 76 of the mountingbracket 72 includes tworecesses 78 which locate twocorresponding projections 84 on the mountingpart 80. One or more of theprojections 84 may include a taperedportion 86 to enable the respective projection to more readily be inserted into the correspondingrecess 78. - The
elongate spacer 80 is locatable between thebracket 72 and thehousing 92, and is configured to extend outwardly from thebracket 72 to space thehousing 92 from the side of afloor panel 24. Theelongate spacer 80 includes a cavity 88 extending along the length of theelongate spacer 80, to lower the weight of theelongate spacer 80 and reduce the quantity of materials used. Theelongate spacer 80 includes achannel 90, which in this example is the same shape as thechannel 76 of the mountingbracket 72. Thechannel 90 of theelongate spacer 80 is positioned on an opposite side of theelongate spacer 80 to the mountingpart 80. - The
elongate housing 92 of theeighth fire seal 68 is mountable to theelongate spacer 80. Theelongate housing 92 includes a mountingpart 94, which is of the same shape as the mountingpart 82 of theelongate spacer 80. The mountingpart 94 of theelongate housing 92 forms part of theextension arrangement 70, and is locatable in either thechannel 76 of the mounting bracket or thechannel 90 of theelongate spacer 80.Figs. 28A to 28D schematically illustrate the mounting of theelongate spacer 80 to thebracket 72, and the mounting of theelongate housing 92 to theelongate spacer 80.Fig. 29 illustrates theelongate housing 92, the elongate sealingmember 16, and thecompression spring 20 of theeighth fire seal 68 in an active position. - It is to be appreciated that a plurality of
elongate spacers 80 may be provided in theextension arrangement 70, for further spacing theelongate housing 92 from thefloor panel 24. Theextension arrangement 70 could be utilised with any of the fire seals describe herein. -
Figs. 30 to 31 illustrate aninth fire seal 94, which is similar to theeighth fire seal 68, but includes anintumescent material 96 inside the elongate sealingmember 97. Theintumescent material 96 expands upon heating and retains theninth fire seal 94 in an active position. - There are thus described fire seals which can be active quite quickly, and in many instances significantly more quickly than conventional intumescent seals. As indicated the fire seals may take a number of different forms as required. The fire seal should provide long term maintenance free operation when required, and will not degrade in a similar manner to intumescent materials. Also inconsistences along the fire seal should not be encountered unlike with intumescent materials. The fire seal is though of relatively straightforward mechanical construction and can thus be inexpensively produced for long term reliable operation.
- The elongate spacer, the elongate housing and elongate sealing member may be made of steel, aluminium or calcium silicate.
- It is to be realised that any of the above combinations can be combined as required. A number of other modifications may be made without departing from the scope of the invention.
- For example a resilient arrangement may take a different form, and could for instance include sprung fingers engageable between the elongate housing and elongate sealing member. Different materials could be used than those described.
- Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
