<p>A suspended ceiling (false ceiling) grid system formed of main runners 10 and cross runners 40 disposed at right angles to the main runners to define grid openings for the reception of ceiling tiles T. Each of the runners 10, 40 includes a bulb 12, 42, a pair of webs 14, 44 hanging from the bulb to define a recess between them, and a pair of tile supporting flanges 16, 46, extending in opposite directions from the lower edges of the webs. The tiles T when assembled onto the flanges 16, 46 of the main and cross runners 10, 40 resiliently displace the webs 14, 44 from their normal unstressed positions to cause the webs to centre the tile. Simulation means 76 are carried by the runners in underlying relationship at the intersection of the main and cross runners 10, 40 to simulate a continuous recess at the intersection.</p> |
