<p>A floor panel which is laid on a supporting construction to provide a base on which a secondary floor covering such as a textile-based carpet or plastics tiles is laid includes an upper sheet steel plate formed from two thin sheet steel plates (26, 28) bonded by a layer of adhesive (30) sandwiched therebetween. The composite plate is stuck onto knobs (20) which extend from a base plate of thermally insulating material and heating pipes (22) extend between the knobs (20) and are looped beneath the plates (26, 28). A layer of adhesive applied to the underside of the lower sheet steel plate (28) forms an array of parallel ridges on the underside thereof. In order to produce an interlocking between adjoining panels, the upper plate (28) is staggered at least along one edge and preferably two edges in relation to the lower plate (26) in each panel so as to produce an overhang along two edges and a rebate along the other two edges of each panel. By appropriately positioning adjoining panels so the overhang along an adjoining edge of one panel will overlie the rebate of the adjoining panel edge and a layer of adhesive will serve to bond the overlapping panel edges together. The adhesive is preferably a two- part adhesive and has sound- deadening characteristics and/or additives. <IMAGE></p> |
