Abstract
A fire wall 10 is adapted to be positioned between an accommodation area and a storage area, and comprises an intumescent sheet or an intumescent paint layer. This sheet or layer may be sandwiched between an outer panel and an inner skin. The outer panel may be moulded from fibre reinforced plastic material or it may be metal, preferably aluminium. The fire wall may be moulded using a reaction injection molding process. In one practical example, the fire wall 10 comprises or forms part of a component shaped to fit items in the accommodation area, for example cushions and it may also be provided with means to locate one or more gas canisters. The fire wall might for example be positioned between an accommodation area of a caravan or a boat, and a storage area containing one or more gas canisters.
Description
Fire Walls The invention relates to fire walls and in particular to a fire wall to be positioned between an accommodation area, for example in a caravan or on a boat, and a storage area, for example to contain one or more gas canisters.
The invention provides a fire wall adapted to be positioned between an accommodation area and a storage area, the fire wall comprising an intumescent sheet or an intumescent paint layer.
The sheet or layer is preferably sandwiched between an outer panel and an inner skin.
The outer panel is preferably moulded from fibre reinforced plastics material.
The plastics material may comprise polyurethane, polyurea, polyisocyanurate, polyester, polyepoxide, ABS, GRP, HIPS, PP or nylon 6.
Alternatively, other materials could be used, such as metal, for example aluminium.
The fire wall is preferably moulded using a reaction injection moulding process.
The reinforcement may comprise glass fibres or a fibre mesh.
The reinforcement fibre may make up 40% to 50% by weight of the panel. A preferred weight is 45%.
A Mica may also be used as a reinforcing agent.
The panel may be from 2mm to 4mm thick. A preferred thickness is 3mm.
The inner skin may be moulded from polyurethane.
The inner skin has a preferred thickness from 0.75mm to 1.25mm, a preferred thickness being 1mm.
The intumescent sheet or intumescent paint layer has a preferred thickness of from 2mm to 4mm, a preferred thickness being 3mm.
The invention includes a structural component, for example forming part of a caravan or a boat, which incorporates a fire wall as defined above, separating an accommodation area from a storage area.
The component may be shaped to fit items in the accommodation area, for example cushions.
The component may provide structural rigidity to the vehicle structure, or form the vehicle structure itself.
The structural component may be provided with means to locate one or more gas canisters.
The location means may comprise a gas locker floor on which is mounted a gas bottle base.
The invention includes a vehicle such as a caravan or boat, incorporating a fire wall as defined above.
By way of example, a specific embodiment of the invention will now be described, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a fire wall according to an embodiment of the invention, incorporated in part of a caravan structure; Figure 2 is an exploded view of the structure shown in Figure 1; and Figure 3 is a perspective view of the fire wall itself.
The structure shown in Figures 1 and 2 is intended to separate the accommodation area of a caravan, from a storage area in the form of a gas bottle locker.
The essential part of the structure is a fire wall 10. The fire wall is made up of an outer panel and an inner skin and sandwiched between the outer panel and the inner skin is an intumescent sheet or intuniescent paint layer. This may not always be the case. The panel may not be a sandwich, it may simply comprise one panel, which is painted.
The outer panel is constructed of glass fibre reinforced polyurethane. The glass fibre makes up 45% by weight of the panel and the panel is substantially 3mm thick.
The inner skin is moulded from polyurethane and has a thickness of 1mm. The intumescent sheet or intumescent paint layer has a thickness of 3mm.
The fire wall is manufactured by arranging the reinforcing material in the mould, mixing together the two parts of the polymer, and then injecting the polymer into the mould under high pressure using an impinging mixer. The mixture is allowed to sit in the mould long enough for it to expand and cure.
Mica may also be used as a reinforcing agent.
Although this embodiment uses polyurethane, other possible materials included polyureas, polyisocyan urates, polyesters, polyepoxides and nylon 6.
When polyurethane is used, one component of the mixture is polyisocyanate and the other component is a blend of polyol, surfactant, catalyst and blowing agent.
Reaction injection moulding produces a strong, flexible, lightweight part which can easily be painted. It also has the advantage of quick cycle times compared to typical vacuum cast materials. The bi-component mixture injected into the mould has a much lower viscosity than molten thermoplastic polymers, and therefore large, lightweight and thin walled items can be successfully processed. This thinner mixture also requires less clamping forces, which leads to smaller equipment and ultimately lower capital expenditures.
The fire wall 10 is moulded to a shape which enables it to be assembled with the other components shown in Figure 2.
To the inner face of the fire wall, which will face into the accommodation area, there is attached a polyurethane insulation layer 11 faced with an inner polyurethane foam skin 12. A front fascia top panel 13 and a front fascia lower panel 14 form a shaped interior, for example to accommodate cushions or other furnishings of the accommodation area.
Sandwiched between the components 13 and 14 and the fire wall is nioulded PVC moulded polyurethane insulation 15.
On the storage side of the fire wall 10 there is a gas locker floor 16 to which is attached a gas bottle base 17 shaped so that two gas bottles can be mounted on the base.
In use the gas bottles are connected to equipment within the accommodation area, in a conventional manner.
If a dangerous situation should result in the gas locker, for example with gas catching fire, then the intumescent sheet or intumescent paint layer expands and provides a heat insulating layer protecting the accommodation area from the locker.
The intumescent sheet or intumescent paint layer could also be used to protect the gas bottles themselves against a fire inside the habitation area, to provide the occupants time to escape.
