Definitions

  • This invention relates to an acoustic door and in particular to an acoustic fire door, i.e. a door having sound-insulating properties as well as fire resistant properties.
  • the invention provides an acoustic door comprising a first metallic panel forming a first side of the door, a second metallic panel forming a second side of the door, and a thermal break element of glass fibre joining the first panel to the second panel and extending essentially around a periphery of the door. As there is no direct contact between the first and second metallic panels, heat is not readily transferred between them.
  • thermal break element usefully enhances the sound insulating properties of the door.
  • each of the first metallic panel and the second metallic panel has a re-entrant rim that extends into a recess of the thermal break element.
  • the thermal break element can have an S-shaped cross-section to provide the recesses, one of the re-entrant rims of the first and second panels extending inwardly and the other of the re-entrant rims extending outwardly. In this way edge elements of the first and second panels can overlap in a direction perpendicular to the panels.
  • the thermal break element can have an E-shaped cross-section to provide the recesses, the re-entrant rims extending in the same direction.
  • the door may be provided with a strip of intumescent material at an edge of the door. This expands when heated, to stop the passage of fire and smoke.
  • the door may be provided with at least one magnetic sealing element at an edge of the door that is arranged to contact a ferromagnetic frame, to provide an effective seal.
  • Thermally activated bolts may be situated within the door leaf which activate under specific thermal conditions to further secure the door within the frame in a fire.
  • the invention provides a combination of an acoustic door as set out above, and a frame for the door, thermally activated bolts being provided within the frame to secure the door to the frame in a fire.
  • two layers of fire-resistant glass can be fitted within the door, one parallel to each of the metallic panels, to provide a fire resistant window.
  • the drawings show a door 2 and a frame 4, against which the door 2 is arranged to close.
  • the door is hinged to the frame by hinges, not shown here.
  • the door 2 includes a first metallic panel 6 and a second metallic panel 8, formed in this example from steel.
  • the first metallic panel 6 has an inwardly directed re-entrant rim 10 and the second metallic panel has an outwardly directed re-entrant rim 12.
  • These rims 10, 12 are lodged in a thermal break element 14, which is S-shaped in cross section to provide recesses 16, 18 receiving the respective rims 10, 12.
  • the edge elements of the first and second panels from which the rims 10,12 depend overlap in a direction perpendicular to the panels.
  • Magnetic seals 20 are provided at peripheral locations on the first and second panels 6, 8, that will contact the frame 4, which is of ferromagnetic material, and provide an airtight seal.
  • An intumescent strip 22 is provided around the edge of the door 2.
  • the strip 22 is provided on a side of the thermal break element 14.
  • the intumescent strip is of a known intumescent material, for example comprising mineral wool fibre, exfoliating graphite and an organic binder.
  • the rims 10, 12, the thermal break element 14, the magnetic seals 20, the intumescent strip 22 and the frame 4 extend around the entire rectangular periphery of the door 2.
  • dog bolts 24 are located along the periphery of the door 2, at the hinged side and the top of the door - Figure 4 showing alternative locations for these.
  • the dog bolts are paired with dog bolt receiver holes 28 within the frame 4.
  • Thermally activated bolts 26 are secured within the frame 4 at specific locations and once thermal activation parameters are met, activate and extend a metallic bar away from the frame and into a thermal bolt receiver slot 30 found in the door.
  • the thermally activated bolts are located in the frame, but they could alternatively be secured within the door and extend into receivers in the frame when activated.
  • the thermally activated bolts are spring loaded and retained by a low-melting-point substrate that melts at the activation temperature.
  • thermal resistant glass 32 Two panes of thermal resistant glass 32 will be secured within the door 2 spaced with an airgap in between acting as a vision panel.
  • the glass-reinforced plastic thermal break element offers a change in impedance whilst maintaining structural stability.
