Abstract (en)
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 ).
