Claims15
A fire resistant structure comprising:
- a pair of parallel walls of combustible plastic with a spacing therebetween;
- an array of strut elements arranged at selected mutual distances in said spacing to form a rigid but permeable core throughout said spacing, each said strut element being bonded at their opposite sides to respective ones of said walls which array of strut elements is bonded to at least one of said walls by means of a flexible carrier cloth which is impregnated by an adhesive;
- a fluid inlet passing through one of said walls;
- a fluid outlet passing through one of said walls;
- and
- means for pumping cooling fluid from the fluid inlet through said spacing towards the fluid outlet.
