<p>A flooring system (10) where adjacent floorboards (60) are fixed to the joists (5) of the supporting structure (SF) by biscuits (20). The biscuits (20) have convergent upper and lower faces (34-37) on side edges (32, 33) for interference fit with elongate grooves (65) in the sidewalls (64) of the floorboards (60). The upper and lower faces (68, 69) of the grooves (65) are inwardly convergent, and the lower sidewall portion (67) of each sidewall (64) is inwardly offset relative to the upper side wall portion (66). The complementary profiles of the biscuits (20) and side walls (64) enable the floorboards (60) to contract and expand without adversely affecting their fixture to the joists (J).</p> |
