Abstract
Disclosed are a fire door and doorway frame and a set comprising both door and doorway frame. The fire door (10) has a peripheral frame comprising top and bottom rails (12, 13) and two 5 upright stiles (15, 16) and a core (20) filling the space within the frame. The core is predominantly composed of a non-metallic fire resistant material particularly an expanded perlite panel. Two face panels (25) substantially completely covering the peripheral frame and the core, the face panels being composed of fire resistant material. The doorway frame is for fitting in a door opening of a building structure, the doorway frame having two upright legs (41), and a head 10 (42) extending between the tops of the legs. A door stop (43) is provided along the height of the legs and along the length of the head arranged so that a door within the doorway frame abuts against the door stop when the door is closed. The two upright legs, the head, and the door stop are all composed of a fire resistant non-metallic material, such as MGO board. 12,4 34___________35____________________,___ Fig.32
Description
invention
The present invention relates to fire doors and fire doorway frames, and to door and doorway frame sets for use in buildings.
Background
Fire doors used in buildings to impede spread of fire are required by buildings regulations and 10 standards to withstand fire for specified times according to a scale of the fire rating for the doors.
For example 2-hour rated doors must withstand exposure to fire for at least 2 hours before failure. The standards are often not met by doors actually being used as a result of manufacturers using materials and manufacturing that are sub-standard, e.g different compositions, different dimensions including thicknesses, and/or manufacturing standards 15 including tolerances.
Doorway frames installed in buildings are often composed of steel upright legs or jambs and steel heads welded to the legs. Such steel frames conduct heat readily from one side of the doorway to the other, and they can distort under the heat of a file and compromise the intended 20 heat barrier. As a result, substantial heat can be transferred across the fire barrier that the door and doorway frame set is intended to provide.
Summary of the Invention
It is an object of the present invention to provide fire doors, and to provide fire doorway frames, 25 and to provide fire door and doorway frame sets for use in buildings that can comply with applicable building fire regulations and standards and provide useful alternatives to existing fire doors and doorway frames.

Detailed Description of Embodiments
Referring to Fig 1, there shown a fire door 10 for fitting in and mounting to a doorway frame of a building structure. The fire door 10 has a peripheral frame 11 comprising top and bottom rails 12, 13 and two upright stiles 15, 16 shown as a lock stile 15 at the side where a lock or latch will be installed, and a hinge stile 16 at the side where the door will be hinged. The door 10 may be additionally strengthened by a cross rail (not shown) between the stiles 15, 16 of the peripheral frame.
2018100774 08 Jun 2018
The space within the peripheral frame 11 is totally filled by a core 20 which is predominantly composed of an expanded perlite material providing fire resistant properties. The core filling the space within the peripheral frame of the door is preferably composed of a unitary piece of expanded perlite material, fibres and binders. Suitable products have low thermal conductivity 5 and weight loss of less than 10% upon exposure to expected building fire temperatures for 2 hours, and linear shrinkage of less than about 1% upon exposure to such temperatures for 4 hours. The core 20 is cut from a unitary panel of the material to form a close fit within the space within the peripheral frame 11. If a cross rail is provided, two close fitting panels of core material will be provided filling the two spaces.
The two face panels 25 are provided on opposite outside faces of the door 10 (only one of the face panels being shown). The face panels completely cover the outer faces of the peripheral frame 11 and the core 20. The face panels 25 are composed of fire resistant non-metallic material. The face panels 25 are preferably composed of fire resistant Magnesium Oxide (MGO) L5 material having a thickness of about 4mm. The face panels 25 may be adhered to the frame 11 and core 20 by any suitable adhesive such as PVA.
The peripheral frame 11 comprising top and bottom rails 12, 13 and two upright stiles 15, 16 is composed predominantly of timber, such as pine. The timber will not combust readily since it >0 will be covered by the fire resistant face panels 25. However if desired the timber can be treated with a fire retardant. The top rail may be 15mm-20mm thickness, and the bottom rail and stiles may be 10mm-15mm thickness.
The fire door has metal structural elements 30 35 for receiving fixings of additional accessories of the fire door, the accessories being selected from: door hinges, door closers, door locks or latches, and door handles. Illustrated are elements comprising perforated steel plates, such as galvanised steel plates of say 0.6mm thickness, for receiving the respective fixings, including plates 30 for enabling fixing thereto of door hinges, plates 31 for enabling fixing thereto of a door closer, plates 32 for enabling fixing thereto of a door lock or latch, and plates 33 for enabling fixing thereto of door handles. Additional plates 34 for strengthening purposed are
2018100774 08 Jun 2018 located between the hinge fixing plates 30 and at the comer between the hinge plate 30 and door closer plate 31. Edge strengthening plates or channels 35 can be provided along the lock stile 15 and/or along the head 12. All of the metal structural elements 30 - 35 are located beneath the face panels 25.
Fig 2 of the drawings illustrates in cross-section a suitable construction of the components of a doorway frame for fitting in a door opening of a building structure. As is conventional, the doorway frame will have two upright legs or jambs 41, and a head 42 extending between the tops of the legs. A door stop 43 is provided along the height of the legs 41 and along the length of the 10 head 42 defining a rebate 44 around the doorway opening so that a door 10 within the doorway frame abuts against the door stop 43 when the door is closed. The two upright legs 41, the head
42, and the door stop 43 are all composed of a fire resistant non-metallic material, preferably a fire resistant Magnesium Oxide (MGO) board, and preferably of about 30mm thickness. The depth of the rebate 44 can be about 50mm deep to receive a door of about 45mm thickness. The stop 43 is initially mounted to the legs 41 and the head 42 by adhesive, such as the synthetic rubber/solvent adhesive “Liquid Nails” available from Selleys (www.selleystrade.com.au), after which fixing screws 45 are installed through the stop 43 and into the underlying legs 41 or head 42.
The doorway frame has an intumescent seal 48 extending throughout the height of the legs 41 and across the width of the head 42, the intumescent seal 48 being spaced from the door stop 43 and is located in a recess so as to face edges of the fire door when closed and is operative so as to expand and seal against the edges of the fire door upon exposure to predetermined heat or temperature expected in a fire.
Particular examples of possible materials and dimensions of components suitable for use in the fire door, fire doorway frame, and set embodying the present invention are:
Stiles 15, 16: 10mm-15mm thick pine
Head rail 12 and bottom rail 13: 15mm-20mm thick pine
Core 20: 30mm-35mm thick board composed of expanded perlite with fibres and binders
