Abstract

The invention relates to a fire barrier 1 that provides a fire safe break between the top of a party wall and a roof covering and comprises a single piece support member 2 having a channel 3 for receiving a gasket 6 of fire resistant material. The support member has a pair of integral sides 7, 8 which extend out sidewards. The sides extend longitudinally beyond the channel at one end 7a and 8a for overlapping with a like fire barrier during assembly. The fire barrier is preferably made from steel and the gasket may be rock fibre. The channel may have a dove-tail cross-section to entrap the rock fibre. The integral sides may have angled portions 9 and 10 that extend upwardly from the integral side portions for the reception of flashing material.

<p>"A sealing system"</p>

<p>Introduction</p>

<p>The invention relates to a sealing system and in particular to a fire barrier for locations between the top of a party wall and a roof covering.</p>

<p>Statements of Invention</p>

<p>According to the invention there is provided a fire barrier to provide a fire safe break between the top of a party wall and a roof covering, the barrier comprising a single piece support member having a channel for receiving a gasket of fire resistant material and a pair of integral sides extending sidewardly thereof wherein the sides extend longitudinally beyond the channel at one end thereof for overlapping with a like fire barrier, on assembly.</p>

<p>In one embodiment the channel is a dovetail shape having an enlarged bottom portion and a narrower top portion for entrapping the gasket.</p>

<p>The sides may extend from the top portion of the channel.</p>

<p>In one embodiment at least one of the sides has an angled portion for supporting a I. 25 flashing or the like. Both sides may have such angled portions. SS S. * * S. * * . S S.</p>

<p>Brief Description of the Drawings</p>

<p>The invention will be more clearly understood from the following description thereof given by way of example only, in which: -Fig. 1 is a perspective view of a fire barrier according to the invention; Fig. 2 is a perspective view of the fire barrier being assembled to a like fire barrier; Fig. 3 is a perspective view of the assembled fire barriers; Fig. 4 is a cross sectional view of the fire barrier; and Figs. 5 to 7 are view of the fire barrier system, in use.</p>

<p>Detailed Description</p>

<p>Referring to the drawings there is illustrated a fire barrier 1 according to the invention which is located in use on top of a party wall to provide a fire break * between the party wall and any roof covering. The fire barrier 1 comprises a single :..::: piece support member 2 of a suitable fire resistant material such as steel. The support **** comprises a channel 3 of dovetail shape having an enlarged bottom portion 4 and a *:: * 25 narrower top portion 5 for entrapping a gasket 6 of a suitable fire barrier material * such as rock fibre.</p>

<p>S. 55.5 :. A pair of integrated side portions 7,8 extend downwardly from the narrow top portion 5 and angled portions 9, 10 extend upwardly from the side portions 7, 8 for reception of flashings or the like.</p>

<p>The side portions 7, 8 extend longitudinally at 7a, 8a beyond the channel 3 at one end of the support member 2 for end overlapping with a like support member 2 on assembly as illustrated in Figs. 2 and 3. This feature is very advantageous because the barriers can be supplied in lightweight short lengths and readily assembled on site to form a barrier of any desired length. Hence, the barrier can be used on any roof size.</p>
