Fire barrier component

Abstract

A fire barrier component has an outer sleeve retaining and protecting a fire stop material therein which is preferably compressed. The outer sleeve when exposed to a fire condition partially fails and the fire stop material forms the fire stop barrier. The fire stop material if compressed expands and can cooperate with adjacent components to form an effective fire stop barrier. The firestop barrier component can be factory made and used in complete fire barrier systems, or the component can be used as part of a specific field application. The component may be sold in longer lengths and cut as required to meet a particular application. Conventional saws work satisfactorily in cutting of the component while maintaining the performance of the component when exposed to a fire condition.

       3 . A fire barrier component as claimed in  claim 2  wherein said fire barrier component has a rated fire stop application and said compressed fire stop material is a non combustible material for the rated fire stop application.  
   
   
       4 . A fire barrier component as claimed in  claim 3  wherein said compressed fire stop material is compressed mineral wool.  
   
   
       5 . A fire barrier component as claimed in  claim 3  wherein said compressed fire stop material is compressed glass fiber material.  
   
   
       6 . A fire barrier component as claimed in  claim 3  wherein said outer sleeve is of a rectangular cross section.  
   
   
       7 . A fire barrier component as claimed in  claim 6  wherein said outer sleeve is a one piece extruded tube.  
   
   
       8 . A fire barrier component as claimed in  claim 6  wherein said outer sleeve is defined by at least two elongate components that cooperate to engage and retain said compressed fire stop material therein.  
   
   
       9 . A fire barrier component as claimed in  claim 8  wherein said at least two elongate components define in an unlocked condition an open channel for locating said compressed fire stop material therein and in a locked condition retain said compressed fire stop material in said outer sleeve.  
   
   
       10 . A fire barrier component as claimed in  claim 3  wherein said compressed fire stop material is compressed in at least a lateral direction across said outer sleeve.  
   
   
       11 . A fire barrier component as claimed in  claim 10  wherein said fire stop material is compressed in at least one direction to at least a third of its non-compressed state.  
   
   
       12 . A fire barrier component as claimed in  claim 11  wherein said component is manufactured in a length exceeding six feet.  
   
   
       13 . A fire barrier component as claimed in  claim 11  wherein said component can be cross cut by a user using a saw.  
   
   
       14 . A fire barrier component as claimed in  claim 13  wherein said component is of a length of at least eight feet.  
   
   
       15 . A fire barrier component as claimed in  claim 3  wherein said outer sleeve includes a series of knockout ports along the length of the component through which electrical wires, pipes or conduits can pass.  
   
   
       16 . A fire barrier component as claimed in  claim 15  wherein said outer sleeve includes at least one internal partition running the length thereof with said compressed fire stop material either side thereof.  
   
   
       17 . A fire barrier component as claimed in  claim 15  wherein said outer sleeve has at least two internal longitudinally extending partitions defining three channels within said outer sleeve, and wherein said knockout ports are associated with a center channel of said three channels.  
   
   
       18 . A fire barrier component as claimed in  claim 17  wherein said component is of a generally rectangular cross section.  
   
   
       19 . A fire barrier component as claimed in  claim 18  wherein said outer sleeve is of a material to be at least partially consumed when exposed to a fire condition and at least partial fail thereby allowing said compressed fire stop material to expand and at least partially protect a portion of the outer sleeve that remains.  
   
   
       20 . A fire barrier comprising a series of elongate fire barrier components held in a side by side configuration wherein each component comprises an elongate outer sleeve of a plastic material and a compressed fire stop material retained and protected interior to said outer sleeve, said outer sleeve being at least semi-rigid.  
   
   
       21 . A fire barrier as claimed in  claim 20  wherein said fire barrier components have a rated fire stop application and said compressed fire stop material is a non combustible material for the rated fire stop application.  
   
   
       22 . A fire barrier as claimed in  claim 21  wherein said compressed fire stop material is compressed mineral wool.  
   
   
       23 . A fire barrier component comprising an outer sleeve of a material that will at least partially fail when exposed to a fire condition, and a compressed fire stop material retained within said outer sleeve; said compressed fire stop material expanding to form a fire stop barrier upon said at least partial failure of said outer sleeve.  
   
   
       24 . A fire barrier component as claimed in  claim 23  wherein said outer sleeve is of a material that is combustible when exposed to a fire condition.
