Definitions
- a fire resisting wall structure comprising two rows of spaced vertical supports or studs, in which the rows of studs are separated by a central layer of fire resisting building board to which the studs of both rows are secured, and the opposite outer faces of the studs are covered by respective facing layers of fire resisting building board secured to the studs, the thickness of the central layer being greater than that of either of the facing layers.
- This invention relates to fire resisting partition walling constructed from spaced vertical supports or studs, secured at top and bottom and having a covering of building board.
- Fire resisting walls have been designed to survive a fire duration with no loss of integrity or insulation performance. This has led to a design where a wall consists of metal studs with boards attached to each side and occasionally insulation in the cavity. As the fire test progresses the layers of boards fall way until finally the wall fails either by heat transfer or through loss of integrity.
- boards made in accordance with our Patent GB-B-2 053 779 which consist of a set cementitious (usually gypsum) core, preferably reinforced with chopped inorganic fibre, and a surface layer on at least one face comprising an inorganic fibre sheet embedded in the gypsum surface so that the material of the core extends in a continuous film over the web outer surface of the sheet.
- This board affords good resistance to spread of flame, owing to its wholly inorganic surface, but also has a high degree of inherent fire resistance arising from the behaviour of the core materials when the board is exposed to fire.
- the residue (Calcium sulphate) continues to act as an insulating barrier for as long as it remains intact.
- Inorganic fibre webs and core fibre reinforcement help to ensure the integrity of the board and to maintain a barrier to the fire for some considerable time after calcination.
- such a fire resisting wall structure comprises two rows of spaced vertical supports or studs of fire resistant material, preferably of metal such as steel, in which the rows of studs are separated by a central layer or core of fire resisting building board to which the studs of both rows are secured, and the opposite outer faces of the studs are covered by respective facing layers of fire resisting building board secured to the studs, the thickness of the central layer being greater than that of either of the facing layers, as illustrated by the example described herein.
- the preferred board is inorganic fibre reinforced gypsum board, for example of the kind discussed above.
- each layer of board is preferably made up of several thicknesses of board.
- the desired thickness of the central layer can be obtained by employing at least two thicknesses of board while the facing layers may consist of fewer thicknesses of board.
- An advantage of the invention is its economy in the quantity of building board required for a given degree of fire resistence. This follows from the location of the majority of the boards, that is, the greater amount of fire resistant material, in the centre layer, where it is protected by the sacrificial outer layers.
- This centre-weighted or symmetrical design enables thinner facing layers to be used than if each facing layer itself had to constitute the main defence against the transmission of fire, which might attack either side.
- the facing layers, or at least the layer on that face exposed to a known fire risk preferably incorporates a material of high fire resistance and integrity, for example a metal (e.g. steel) sheet; this can be used to maximise the potential of the air cavity or may serve to reduce the number of thicknesses of board employed in the outer layers.
- This wall is designed to maintain 4 hours fire resistance at extended heights and consequently when tested at 3m height achieves 5 hours fire resistance.
- the traditional failure criteria do not apply, and the critical factor is the temperature of the cold metal frame at 4 hours duration.
- the cold metal frame has a temperature of approx. 100°C with a small temperature differential over the stud at the four hour duration, which allows the design to be used at extended heights. - 5 -
- a first framework in erecting the partition shown in the drawing, includes a metal head channel and base channel which are fixed at 600mm centres to the adjacent floor and ceiling surfaces respectively. Strips of inorganic fibre reinforced gypsum board 72mm wide and 25mm thick are interposed between the channels and the surfaces to which they are fixed. Metal studs 10 are then positioned at 600mm centres between the head and base channels. The end studs at the sides of the partition are fixed to the adjacent wall at 600mm centres through another strip of inorganic fibre reinforced gypsum board.
- a first layer 11 of 15mm board is fixed by 25mm screws at 300mm centres to all metal framing, a second layer 12 of 25mm board by 42mm screws at 300mm centres and the third layer 13 of 15mm board by 75mm screws at similar spacing.
- the joints between the boards are staggered with respect to adjacent layers, with a full board at the fixed edge.
- a second similar metal stud framework (but using 50mm thick strips of board at the head, base and sides) is constructed alongside and in contact with the three layers of board.
- the studs 14 in the second framework are staggered by 300mm with respect to the studs 10 in the first framework, and the second framework is fixed to the three layers of board 11-13 using 75mm screws.
- each framework is then lined with 0.7mm steel sheet 15 fixed at 300mm centres with 13mm wafer head screws.
- a layer of 25mm board 16 is fixed to the steel sheet using 25mm screws at 150mm centres round the perimeter and down the centre of the boards, and an outer layer of 15mm board 17 is fixed through to the steel sheet at 300mm centres using 42mm screws round the perimeter and down the centre of the boards.
- the vertical joints between the boards in the outer layers are positioned such that no joint is in alignment with the position of a stud. All joints are taped and filled, and screwheads spotted, with a conventional joint filler.
- the channels and studs are of cold formed hot dipped galvanised steel in accordance with BS 2989 (EN 10142)
- the boards are glass fibre reinforced gypsum board in accordance with UK Patent GB-B-2 053 779, preferably as sold under the designation "Glasroc S' .
