floor panel in this figure to cover five props may of course be varied to cover three or four props depending upon the floor loading type of panel and amount of access which may be required fig9 shows a side view of a corner clamp 65 the clamp includes an upper plate 66 which in use is mounted flush with the floor panel surface and a downwardly depending leg 67 supported by webs 68 the webs 68 also act as dividers between floor panels to prevent them from rubbing against each other when dynamic loads foot or trolley traffic are applied across the upper panel surfaces this permanent panel separating device provided by the webs 68 is a feature of this invention it enables easy initial and subsequent location of floor panels plus it prevents squeaking between adjacent panels a central aperture 69 is countersunk at 70 to enable a screw threaded fastener 71 to hold down the corners of four adjoining panels fig1 shows a single prop 22 of a floor support module having a central aperture 25 into which the screw threaded fastener 71 is received the floor panels 61 have a corner rebate 72 machined in them to receive the corner clamp 65 in use an adhesive bed 73 is placed under the bottom pad of the prop 22 and when the panels 61 are placed on the floor support module and the fastener 71 screwed down the thick adhesive bed 73 may be expanded or mostly expelled from under the prop or alternatively contracted or minimally sucked upwards thereby affecting its thickness before curing this action of the adhesive during the clamping down of four adjoining panels is a feature of this invention it enables the finite.
