ABSTRACT:
A suspended ceiling construction comprises a plurality of individual ceiling tiles suspended in rows between evenly spaced support beams. Each tile has a kerfed back edge that fits over a flange on a back support beam and an L-shaped front portion having a lower lip that fits under a flange on a front support beam. The side edges of each ceiling tile include longitudinal kerfs therein extending rearwardly from the front portion of the tile, with the kerfs being positioned above the lip on the front portion of the tile by a distance at least equal to the thickness of the flange on the front support beam. Tile supporting splines fit into the kerfs in the sides of abutting ceiling tiles and engage the front support beams. At least one of the ceiling tiles is an access tile and comprises cut away portions above the kerfs on each side of the tile. The splines include a movable member slidable from a locking position, engaging the kerfs at the side edges of the tiles, to a release position at the cut away section. The movable member has a flange sized to pass through the opening at the cut away portion such that the splines in that tile may fit through these open sections when the splines are in their release positions. These open sections permit the removal of the tiles from the ceiling for access to the space above the suspended ceiling.
