The invention relates to a method for installation of ceiling tiles in an improved mounting hook assembly to form a concealed grid system, the mounting hook assembly being attachable to a mounting stud (1) having recess on top portion to accommodate screws and fixed at the back of each tiles, and consisting of a rotating load bearing lever member (LL) that transfers the weight of the tile onto a flange of a suspending inverted T bar grid; a short rotating lever member (PL) assigned for positioning the tiles with pre-determined length so that the PL lever when facing the T grid on either side of the tiles, a distance between the ends of positioning levers on opposite side is less than the opening in the grid; a plurality of screws and washers, the method comprising attaching the mounting hook assembly to the tile; rotating the load bearing lever member; rotating the positioning lever member to position the load bearing member on the flange of the T grid bar; and fixing the tile below the T grid at a distance that is greater than the thickness of the tile so that when the tile is lifted up, the load bearing lever are returned to a position above the flange level of the T grid and any tile can be removed or installed in totally concealed grid system without dislocating tiles already laid. |
