Abstract

A fire resistant door is built up from timber frame members (1, 2) with non combustible heat insulating boards (15) in grooves (12) in the frame members. The frame members are glued and/or stapled together, and decorative hardboard panels (11) are secured on either side, covering the frame members and the boards. Intumescent paint (13) is included between the joints between the frame members and the boards, and also at (20) around the edges of the frame. <IMAGE>

Description

SPECIFICATION Doors This invention relates to doors or panels and one object is to provide a door which has fire resistance while yet it can have a very pleasing appearance but be cheap to manufacture.
According to the present invention, a door or panel comprises a frame, a decorative panel secured on at least one side of the frame, and non combustible heat-insulating boards in the spaces in the frame and bounded by the panel or panels.
There will usually be two decorative panels, one on each side of the frame, but there may be applications where a pleasant appearance is only required on one side, so that a single decorative panel will be used. Such a panel can be die pressed hardboard in the form of a skin, perhaps 1/8 of an inch thick and can be embossed to have the appearance of an expensive panelled door. The panel may be primed ready for the application of any finishing paint or varnish.
Such a hardboard panel has little fire resistance, but the frame can be of timber members with a cross-section of the order of 1 2 x 16 inches and the boards provide sufficient insulation to prevent the panel on the other side from igniting.
The faces of frame members facing the spaces can have grooves for location of the boards, and the grooves can be lined with intumescent material which will expand when heated to seal any gaps at the edges of the boards.
The invention may be carried into practice in various ways, and one embodiment will now be described by way of example with reference to the accompanying drawings, in which: FIGURE 1 is an elevation of the finished door; FIGURE 2 is a corresponding elevation of the frame used in forming the door of FIGURE 1; FIGURE 3 is a cross-section on the line Ill-Ill in FIGURE 2; and FIGURE 4 is a detail of FIGURE 3 to an increased scale.
Two door panels 11 are as shown in FIGURE 1 and are die-formed from sheet hardboard to be embossed to have the appearance of a conventional panelled door. In the example shown in FIGURE 1 , there are six panels. The hardboard is 1/8 of an inch thick.
A frame is built up as shown in FIGURE 2, from frame members 1, 2, and 3.
The outer frame members 1 are of rectangular cross section with a groove 12 in one face, while frame members 2 and 3 have grooves 12 in opposite faces.
The frame members are built up as shown in FIGURE 2, so that they correspond in position to the non-embossed parts of the panel 1 The frame members can be connected together by glueing and stapling, and it will be seen that there are voids or spaces A.B.C.D.E.F. bounded by the frame members 1, 2, and 3, and corresponding in position to the embossed panels of the skin 1 1 of FIGURE 1.
The transverse outer frame members 1 at top and bottom are formed with tongues which locate in the grooves 12 in the vertical members 1.
The grooves 12 have their bottom and side surfaces painted with an intumescent paint 13 (Figure 4) before assembly, and during assembly, boards 15 are located in the painted grooves to fill the voids A-F. They are preferably a snug, or perhaps slightly loose fit.
They are of non-combustible, fire resistant, material perhaps 1 2.mm. thick, for example that known as Thermax (RTM) - Density 675.
Then the panels or skins 1 1 are glued to the sides of the frame with the embossed panels extending into the spaces A-F as shown at 16 in FIGURE 4.
In a fire test, the hardboard panel 11 is burnt away quite quickly on the side of the fire, and then the intumescent paint 13 expands under the increased temperature to fill any spaces around the edges of the boards 1 5 within the frame members 1, 2, and 3.
The boards 1 5 act as an insulator and, a combination with the frame and paste 13, keep high temperatures, smoke and flames from crossing to the other side of the door.
In the outer edges of the member 1, a palusol 100P intumescent strip in a PVC casing can be fitted as shown at 20 to expand when heated to fill the gaps between the door and the door frame.
It may not be necessary under the bottom member 1.
It will be appreciated that although the construction is very simple, the fire resistance can be very good, and the appearance excellent.
1. A panel member comprising frame members secured together as a frame defining spaces between the frame members, a decorative panel secured to one side of the frame, and noncombustible, heat-insulating boards located in relation to the frame members and closing the spaces.
2. A panel member as claimed in Claim 1 in which the boards fit in grooves in the sides of the frame members facing the spaces.
3. A panel member as claimed in Claim 1 or Claim 2 including intumescent material between the faces of the frame members and the edges of the boards.
4. A panel member as claimed in any of Claims 1, 2, and 3, including a second decorative panel secured to the other side of the frame.
5. A panel member as claimed in any preceding claim in which the frame members are of timber.
6. A panel member as claimed in any preceding claim in which the, or each, decorative panel is of hardboard.
7. A panel member as claimed in any preceding claim constituting a door.
8. A panel member constituting a door as claimed in Claim 7, including intumescent material in grooves in the outer faces of the frame for filling
