Definitions

  • the present invention relates to a device for closing at elevated temperature an aperture in a partition, through which aperture at least one plastic pipe passes.
  • pipe as used herein is intended to include tubes, ducts, and other elongate hollow bodies of generally uniform cross section.
  • plastic is used herein to mean materials from which pipes can be made and which at elevated temperature, as under fire conditions, are soft such that they can be cut or deformed and/or burn away.
  • a material is e.g. polyvinyl chloride, which is hard at normal ambient temperatures but softens at elevated temperature.
  • a device for closing an aperture in a partition through which aperture a plastic pipe passes, when the pipe is subjected to elevated temperature causing the wall of the pipe to soften comprising: at least one closure member or shutter for mounting adjacent the wall of the pipe and externally of the pipe, the closure member or shutter being adapted to cut through the pipe when the pipe softens at elevated temperature; and means acting on the closure member(s) to urge said memeber(s) inwardly of the wall of the pipe to effect closure of the aperture when the wall of the pipe softens.
  • a device for closing an aperture in a partition through which aperture a plastic pipe passes, when the pipe is subjected to elevated temperature causing the wall of the pipe to soften comprising: at least one closure member or shutter for mounting adjacent the wall of the pipe and externally of the pipe; means acting on the closure member(s) to urge said member(s) inwardly of the wall of the pipe to effect closure of the aperture; and a thermal link connected to the or each closure member or shutter for maintaining the closure member or shutter offset from the pipe under normal conditions, the thermal link releasing the closure member or shutter when subject to a temperature exceeding a predetermined value so that said means causes the shutter to effect closure of the aperture.
  • the closure member or shutter may carry intumescent material on at least one side thereof so that when the aperture is closed, the portion of the pipe on said at least one side of the shutter is sealingly closed by intumescence of the intumescent material.
  • the device 21 shown therein comprises a frame or support 22 formed by a steel sheet in which an aperture or opening 23 has been cut.
  • the frame 22 has attached thereto two L-shaped flanges on opposite sides of the opening 23, the free edges 24' of the flanges being directed towards each other, the flanges thereby forming, together with the frame 22, guides or tracks in which a shutter 25 is slidable.
  • the shutter 25 is fastened by a thermal link 26 (shown only diagramatically in the drawings) to the frame 22.
  • a pair of coil tension springs 27 are connected between the shutter 25 and the frame 22 and urge the shutter downwardly (as viewed in Figure 1).
  • Stops 28 are provided on the frame 2 as shown, or may alternatively be provided within the guides or tracks referred to above.
  • the device 21 is mounted on a partition 30. ( Figure 2) having an aperture 31 through which a plastic pipe 32 passes, the pipe being a close fit in the aperture.
  • the pipe 12 passes through the opening 23 of the frame 22 and the shutter 25 is arranged offset from the aperture 21 and the pipe 32 with its knife edge 29 adjacent the pipe.
  • the pipe 32 becomes heated and therefore softens and/or may catch light and start to burn away.
  • the thermal link 26 When the thermal link 26 reaches a predetermined temperature it melts or breaks releasing the shutter 25, which is then pulled by the springs 27 across the aperture 21 in the partition 20 to engage the stops 28 and thereby closing the aperture.
  • the shutter 25 itself, as it moves across the aperture 21, deforms the pipe and/or its knife edge 29 cuts through the pipe, which has been softened by the heat of the fire.
  • the aperture 71 is closed by the shutter 25 thereby preventing or at least inhibiting combustion products and flame passing through the aperture and the portions of the pipe on either side of the shutter 25 are sealingly closed by the shutter at their cut or deformed ends.
  • the intumescent material 35 intumesces under the heat of the fire and provides a seal between the partition 3 and the shutter 25 around the perimeter of the opening 23 and also serves to effect sealing of the pipe at its adjacent cut surface.
  • the glass fibre mat 36 serves to apply the pressure generated by the intumescing of the intumescent material 35 over its entire area to the area of the partition 30 around the opening 23 and to the adjacent cut surface of the pipe to enhance the sealing of the opening and of the pipe at that surface. Also if the fire is on the side of the shutter 25 remote from the intumescent material 35, the intumescent material serves to inhibit transmission of heat to the cut surface of the pipe adjacent the intumescent material.
  • the intumescent material and a glass fibre mat may be similarly provided on the face 25" of the shutter 25 in addition to or instead of on the face 25' of the shutter so as to seal the pipe as its cut surface adjacent thereto in the event of a fire.
  • the frame 22 may be coated with intumescent material to assist in sealing the aperture 11 under fire conditions.
  • the device 21 may be mounted between the skins of a double-skinned partition and thereby be concealed within the partition.
  • the openings 23 may be circular and of a diameter such that the pipe 22 is a close fit therein.
  • the device 21 may be modified so that it can be fitted around a pipe already installed in position and passing through an aperture in a partition.
  • the device 21 may be used in association with a range of sizes of aperture in a partition. I.e. the device 21 is not restricted to use in association with an aperture of particular size in a partition.
  • the remaining lengths of the pipe may be of metal or other material more resistant to heat.
  • the intumescent material referred to above may be as described in our British patent no. 1601131 or British patent applicaton no. 8421431.
