(54) A T-BAR WITH CONNECTING SLAT FOR FIXING COMPONENTS OF SUSPENDED CEILING


(57) A subject of this invention is a T-bar with connecting slat (1) for fixing components of suspended ceiling which in web (3) has a rectangular opening (4). The opening (4) slide fits the slat (5), formed from parallel metal sheets (5' and 5") joined permanently together. The opposite pairs of boundary strips of each sheet metal are bent outside so that they embrace edges of the opening (4), in parallel to the longitudinal axis of bar (1). On the bent boundary strip of metal sheet, there is at least one groove forming a notch (9) from the side of web (3), and on the surface of web (3), on the edge of opening (4), there is at least one groove (8), which forms a latch together with the notch (9). The connecting slat (5), in the light of opening (4) made in the web (3) incorporates pass-through shaped slots (6).
