Description

  • This invention relates to fire resistant panels.
  • As safety requirements in industry increase, ever more sophisticated panel structures meeting ever increasing specifications for use in resisting the advance of fires for specified periods of time have been proposed. Panel structures are thus being proposed which are increasingly expensive. Frequently in the construction industry use is made of steel sheeting and of sandwich structures containing cement material. An example of such a structure is disclosed in WO-A- 93 20300. Technology developed in the construction industry is occasionally extended to meet the requirements of high specification fire resistance.
  • It is an object of the present invention to provide a relatively low cost high specification fire resistant panel system which is fire resistant from both sides.
  • According to the present invention, there is provided a fire resistant panel structure comprising an opposed pair of fire resistant panels each comprising two metal sheets separated by a filling formed of cement, the panels each having first thicknesses which may be the same or different and, sandwiched between the panels, is a central thermally insulating board having a second thickness greater than either first thickness. In the preferred practice, the two opposed panels will be identical in dimensions and structure.
  • In one panel structure embodying the invention, the opposed pair of panels and insulating board are held together by fire-resistant adhesive applied to all mating surfaces.
  • A panel structure embodying the invention provides fire resistance by means of the opposed pair of panels and fire and thermal insulation by means of the insulating board. The fire resistant panels will protect the insulating board from direct contact with the fire which would otherwise cause surface erosion of the insulating board and reduce its insulating properties.
  • The fire resistant panels may typically be of a cement and steel sheet composite such as that known by the trade mark "Durasteel". Such a composite will offer additional useful properties, such as resistance to impact, moisture, ballistic and criminal attack. The steel element of the composite will form a Faraday Cage which causes attenuation of electromagnetic waves. Such composite boards are readily available and of relatively low-cost. However other fire resistant panels of cement/metal sheet structure as required by the panel structures of this invention may also be used if further specific properties are required.
  • The insulating board is preferably a thermally insulating board formed of calcium silicate of low density (260 kg/m2 at a thickness of 50 mm) which will enable it to perform its insulating function at high temperatures. Other materials can be used which provide similar properties. Calcium silicate board thicknesses tend to be greater than those of many fire resistant boards and this is a desirable property where insulating behaviour is required. Typically, fire resistant panels as aforesaid can be manufactured with a thickness of as little as 6 mm overall to be used with calcium silicate insulating board having a thickness of the order of 50 mm.
  • When built into an insulating fire barrier system, panel structures embodying the invention can be held together by means of cover strips made from the fire resistant panel material comprised thereby. The cover strips are preferably held in place by screws connecting through to the fire resistant panel of the panel structure. Such structures are self supporting and it is merely necessary for steel angles to be fixed to surrounding masonry and panels to hold to the system in place. The panels may be cut to size to suit the shape of the barrier to be formed and holes cut to accommodate services that need to pass through the barrier. Joints between the panels and masonry may be sealed with fire resistant compositions to prevent passage of fire. Similarly, the services passing through the panel may be sealed with suitable fire stopping material.
  • For a better understanding of the invention and to show how the same can be carried into effect, reference will now be made by way of example only, to the accompanying drawings, wherein:-
  • Figure 1 is a perspective view of a panel structure embodying this invention; and
  • Figure 2 is a section through a joint between a pair of panel structures embodying the invention.
  • Referring to the drawings, Figure 1 shows a pair of fire resistant panels 1 and 2 each made up of a pair of thin steel sheets 3 and 4 between which is sandwiched a body 5 of cementitious material. An insulating panel 6 formed of calcium silicate is adhesively bonded to each such panel by means of a fire resistant adhesive.
  • Referring to Figure 2, a pair of panels 1 abut at a joint 7 over which are laid a pair of cover strips 8 secured to each of the panels 1 by screws at positions 9, 10, 11 and 12.
