Abstract
An access floor panel (180) comprises a central core (2), a lower tray (20), and an upper flooring lid (10) which form an envelope for the core (2). The panels have a fire resistant seal or barrier (25) for sealing between the tray and lid (20, 10). The ends of the tray and lid (20, 10) are kept apart and the barrier (25) seals against the core (2) and each of the ends (181, 182) of the tray and lid (20, 10) to complete the enclosure. The seal (25) acts as a fire stop.

FIG. 16 , in this case the retaining means comprises a separate component which may be provided by a suitable fixing such as a pin orstaple 171. - Referring to
FIGS. 17 to 19 there is illustrated anotheraccess floor panel 180 of the invention which is similar to the panel described with reference toFIG. 1 and like parts are assigned the same reference numerals. In this case a fireresistant seal 25 in the form of a strip is applied to thecore 2 and theends lid 10 andtray 20 are simply downturned to separately engage theseal 25. The ends 181, 182 of thelid 10 andtray 20 are separated by theseal 25 for enhanced fire performance. One particular advantage of this arrangement is simplicity of construction. The panel is also reversible. In this case the seal is of a plastics material bonded to thecore 2, for example using a suitable adhesive. - A fire test was carried out on the panel of
FIGS. 17 to 19 . The panel reached Class RE130r under a 1.5 kN load in accordance withEN13501 part 2. - In some respects
FIGS. 17 to 19 illustrate the simplest version which rely on material bulk for strength as opposed to geometry of the steel. The internal edge band serves as a gap filler only. - In principle the last of these is the most simple but most rely on the same response to heat: The lower steel tray, exposed to heat, expands and contacts the adjacent trays, also expanding, this protects the side of the panels from direct heat. The plastic, which may be ABS, simply melts away and gasses off.
- The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
