Definitions

  • Walls, floors and ceilings of a building usually a multi-storey building commonly have pipes, ducts and conduits formed of a plastics material which penetrate the wall, floor or ceiling for carrying services for example water, sewerage or electrical services.
  • the penetrating pipes, ducts or conduits allow flames and/or smoke and gases to spread rapidly through the wall, floor or ceiling.
  • a number of devices are currently known for use in conjunction with plastic services pipe or ducts for closing off the pipes or ducts in the event of fire.
  • the pipe is not fully sealed by the heat expandable material and thus they are not fully effective as fire barriers.
  • Retention devices are essential to retain the intumescent material in their housing however, often the retention devices are not effective with that result that the intumescent material as it expands can fall out of the housing or sleeve and slab.
  • the intumescent material in plastic housings is usually retained in the housing by means of a metal retaining ring. When the intumescent material expands under the influence of heat, it tends to push the ring out of the housing and thus the intumescent material also falls out.
  • the present invention in a further aspect provides a method of manufacturing a fire barrier device for use with pipes, ducts or conduits passing through a wall, floor or ceiling of a building and having a substantially annular main body portion adapted to be located about said pipe, duct or conduit, said method including the step of injection moulding said fire barrier device from a material containing a heat reactive expandable material.
  • the barrier device is installed within and adjacent one side of the slab.
  • the main body has a maximum transverse dimensions located in use at a position spaced from one side of the slab to resist detachment of said main body from said one side of the slab. Such a configuration will ensure that the main body will be retained within the slab by the material thereof.
  • the collar of heat expandable or intumescent material may be formed integrally with the hollow body which itself is thus formed of the heat expandable material or alternatively, the annular collar is separate of the hollow body and may be located thereover coaxially.
  • the annular collar may supported or seat on a shoulder formed in an external wall of the hollow body.
  • the annular collar may be of any cross sectional form but typically may have a curved outer configuration.
  • the annular collar suitably extends radially outwardly of the body so as to be retained in the material of the slab.
  • a sleeve may be associated with the device to act as a stack through the slab for accepting the pipe, duct or conduit therethrough, the sleeve being of such a length as to project beyond the slab when formed.
  • the sleeve may be secured to any part of the device such as to the collar of the device where provided for example by adhesives or mechanical fasteners.
  • the sleeve may be formed integrally with the device and extend coaxially therefrom relative to the axial bore through the body.
  • the formwork is formed of timber and is removed after formation of the slab.
  • the formwork may be metal decking sheets such as that known as Bondeck and remain in situ after curing of the slab material.
  • the fire barrier devices in such situations are secured to the metal sheets by metal fasteners such as screws or rivets and a circular opening is formed in the metal decking in alignment with the fire barrier device to enable the service line or pipe to be passed therethrough.
  • the opening may be formed before or after affixing of the fire barrier device.
  • radially extending stop means may be associated with the fire barrier device to span the device adjacent the mounting flange, the stop means being abutted by the end of the pipe.
  • FIG. 9 is a cross sectional view of the device of FIG. 7 installed within a slab.
  • FIG. 11 is a sectional view of the fire barrier device of along line A-A of FIG. 10 with associated clamping ring;
  • FIG. 12 illustrates the manner in which the fire barrier device of FIG. is installed within a slab

  • FIG. 25 illustrates in sectional view the manner in which the fire barrier device of FIGS. 23 and 24 is installed within a slab
  • the moulding material also includes a plasticiser or carrier for example HDPE to enable moulding, a smoke suppressant and a fire suppressant for example sodium silicate.
  • the main body 11 is circular in cross-section and has an external part spherical wall 13 centred on the central axis of the body 11 in which is formed an annular groove 14 .
  • Wall 13 has a maximum diameter adjacent the mounting portion 12 and the body 11 is stepped inwardly adjacent portion 12 to present an annular wall portion or shoulder 13 ′ which faces the mounting portion 12 .
  • the device 10 may be used in a number of different situations to close off pipes, ducts or conduits passing through walls, floor or ceilings. Most commonly, however the device 10 may be installed within a concrete or concrete composite slab wall, floor or ceiling during its construction in the manner shown in FIGS. 3 and 4. A pipe 23 is initially passed through the collar 15 such that it is frictionally gripped by the internal wall thereof and thereafter the device 10 may be secured to formwork 24 which defines one face of a concrete slab to be formed. This is achieved by means of the flange 21 of the device 10 which is seated on the formwork 24 with cleats 25 or other fasteners located by the slots 22 drive into the formwork 24 to clamp the flange 21 and thus the device 10 to the formwork 24 .
  • the concrete or concrete composite material 26 may then be poured or deposited onto the formwork 24 and around the devices 10 secured to the formwork 24 and pipe 23 until the required thickness of the wall, floor or ceiling slab 27 is achieved. As shown, the pipe 23 extends above or beyond the slab 27 to enable connection to further pipes to form the service line through the slab 27 .
  • the formwork 24 is removed as shown in FIG. 4 which leaves the device 10 embedded in the concrete slab 27 . The device is retained in the slab 27 due to the radially enlarged form of the main body 11 of the device which is embedded within the slab 27 .
  • Retention is further enhanced by the interlocking achieved through the material 26 of the slab filling the annular groove 14 and further because of the slab material filling the undercut annular space 28 between the shoulder 13 ′ and the annular wall 19 .
  • the device 10 is thus anchored within the formed slab wall, floor or ceiling.
  • a first HDPE pipe 40 is inserted into the device 33 to be gripped by the collar 15 and supported in an upstanding attitude prior to pouring the settable material on to the formwork 24 (shown in dotted outline) to form the slab 27 .
  • the sleeve 37 may then be engaged with the lower end of the pipe 40 in the space 29 with the radially extending recess 35 accommodating the radially extending terminal or terminals 38 of the sleeve 37 providing sufficient room for receipt of the connecting plugs of the wires 39 .
  • the devices 10 , 31 and 33 are preferably installed within a slab, they may be secured to one or both sides of a slab and around a service line or pipe extending through the slab or in a ceiling space.
  • the devices (or 31 or 33 ) may be secured to a plasterboard ceiling panel with an enlarged 10 opening formed in the panel in alignment with the device 10 (or 31 or 33 ) such that a pipe 23 supported by the device 10 (or 31 or 33 ) may be secured to a further pipe or fitting through a female socket on the end of the further pipe or fitting which locates within the enlarged opening and space 29 in the device 10 (or 31 or 33 ).
  • the device 10 (or 31 or 33 ) will function in the same manner as that described above to shut over the service pipe in the event of fire.
  • FIGS. 10 and 11 there is illustrated a fire barrier device 42 according to a further embodiment of the present invention, the device 42 comprising or consisting of a heat reactive intumescent material and being moulded in one piece in any suitable moulding apparatus.
  • the device 42 is of a generally hat shaped configuration in side view and includes a main body 43 which is circular in cross-section and which has a generally spherical outer configuration defined by an external curved wall 44 such that the diameter of the body 43 in the middle thereof is greater than the diameter at each end for a purpose which will become apparent.
  • devices 42 may be initially secured to the formwork 55 at the desired positions where the service pipes or ducts are to penetrate the slab and thereafter the pipes or ducts 54 are inserted into the devices 42 to be upstanding therefrom in the manner shown, the lengths of the pipes or ducts 54 being such that they will extend beyond the side of the wall, floor or ceiling slab to be formed opposite the formwork 55 .
  • the concrete or concrete composite material 56 may then be poured or deposited onto the formwork 55 and around the devices 42 secured to the formwork 55 and pipe or duct 54 until the required thickness of the wall, floor or ceiling is achieved. As shown, the pipe or duct 54 extends above or beyond the slab to enable connection with joining pipes or ducts. After the concrete or concrete composite material has cured or set, the formwork 55 is removed as shown in FIG. 13 which leaves the device 42 embedded in the concrete slab.
  • the leg 74 terminates in an annular flange 76 which may be secured to the formwork 55 by cleats through the flange 76 or by a separate clamping ring 50 as in the embodiments of FIGS. 10 to 17 .
  • the pipe 54 is gripped by the walls of the bore 73 which support the pipe 54 in an upstanding attitude whilst the concrete 56 is applied to the formwork 55 .
  • the leg 74 forms with the pipe 54 a space 77 which allows rapid passage of heat of the fire to the collar 72 of the device 70 to cause rapid expansion thereof as shown in dotted outline to close over the pipe 54 .
  • the space 77 also allows for connection of the pipe 54 with a further pipe in a similar manner to that shown in FIG. 13 after the formwork 55 has been removed.
  • the device 70 as well as being used within a slab may also be used in a ceiling space as in the arrangement of FIG. 17.
  • FIGS. 19 to 21 there is illustrated a fire barrier device 78 according to a further embodiment of the present invention, the device 78 comprising an annular spacer 79 preferably formed of metal having an annular side wall 80 , an annular flange 81 at one end of the wall 80 and a disc-like end wall 82 (see FIG. 21) at the opposite end of the side wall 80 and extending inwardly towards the central axis of the spacer 79 .
  • Seated upon the end wall 82 is an annular body 83 moulded from a material comprising or consisting of a heat reactive intumescent material as described above.
  • the body 83 is circular in cross-section and has an upper collar 84 and a curved external wall 85 curving inwardly from the outer periphery of the spacer 79 to the collar 84 .so as to be externally of part-spherical form.
  • the body portion 85 has an internal bore portion 86 of an internal diameter greater than the internal diameter of the collar 84 and has in its external surface 85 an annular radially inwardly extending groove 87 .
  • the body 83 is attached to the spacer 79 by any suitable means such as by suitable adhesives or by a mechanical connection.
  • the mechanical connection may include lugs on the body 83 which locate in slots or apertures in the disc-like wall 82 .
  • the body portion 85 may be locked to the spacer 79 by rotating one relative to the other.
  • the body 85 may include downwardly extending headed lugs which may locate in keyhole shaped apertures in the wall 82 such that when rotated relative to each other, the body 85 becomes mechanically connected to the spacer 79 .
  • the collar 84 has an internal bore which is of a diameter substantially the same as the diameter of a pipe or duct to be passed through the device 78 .
  • the bore 86 in the body 83 defines with the pipe or duct 90 , an annular space 95 which ensures that in the event of fire, the generated heat will be directed towards the inside of the body 83 so that the intumescent material thereof is rapidly subject to heat which will cause it to expand and close over the softened pipe 90 as illustrates in dotted outline in FIG. 22.
  • the curved nature of the external wall of the body 83 ensures that there is a concentrated expansion of the intumescent material as indicated by the arrows in FIG. 22 reacting against the surrounding slab material 93 which directs the forces generally radially as illustrates to rapidly close over the softened pipe 90 as indicated in dotted outline.
  • space 95 facilitates the connection between the pipe or duct 90 and a further pipe or duct 96 (shown in dotted outline) having a mating female socket for joining to the end of the pipe or duct 90 within the space 95 by suitable adhesives usually contact adhesives.
  • FIGS. 23 to 26 illustrate a further embodiment of fire barrier device 98 according to the invention which in this case includes a sleeve-like body 99 which has a wall 100 having a number of outward steps and which terminates in an annular flange 101 , the body 99 suitably being formed of a plastics material. Supported on one stepped portion or shoulder 102 of the wall 99 is a ring 103 of heat expandable material, the ring 103 having a curved outer wall and being self-supporting and being suitably moulded from a material comprising or containing intumescent material as described above to be of a relatively rigid construction.
  • the device 98 is used in a similar manner to that described above with the flange 101 being secured by cleats or nails 106 to formwork 107 as shown in FIG. 25 and a pipe or duct 108 inserted into the body 98 to be gripped by the upper end 105 of the body 99 to be supported in an upstanding attitude.
  • concrete or other settable material 109 is applied to the formwork 107 to form the slab 110 , the formwork 107 being removed after curing or setting of the material 109 .
  • the device 98 remains in situ within the slab 109 as shown in FIG.
  • the sleeve-like body 99 may have at its upper end 105 an internal annular recess for engagement by a puddle flange of conventional form which locates about a penetrating pipe 107 .
  • the intumescent material of the devices of the invention is self-supporting within or out of a slab.
  • the intumescent material from which the heat expandable bodies of the devices are formed may form a mechanical and/or chemical bond with the material of the slab to further assist in retention of the bodies within the slab.
  • the devices additionally are highly resistant to weather conditions, moisture or other adverse environments. Further whilst the devices are preferably of circular cross section, they may be of square cross sectional form or of any other cross section. Of course, the devices and the bores therein may be varied in size to suit the application and the size of pipe, duct or conduit with which the devices are to be used.
