A fixture (10), which according to the invention, is utilised to attach tracks of asphalted roofing-board (22) to an underlying layer of insulation slabs (22) simply and shall be attached on a false ceiling (20) of concrete or other appropriate material in a separate attachment operation. The fixture has a securing hole (15) located in the middle for receiving an expansion device (16), which projects down on the bottom of the fixture, while a setscrew (17) project up from the fitting and expansion device on the top of the fitting. A single saw tooth-shaped attachment claw (14) project down at right angles from the opposite ends of the fixture at the longitudinal central axis of the fitting. This has its main plane pointed directly the fixture's longitudinal central axis. Along the side edges of the fixture's rectangular main surface (11), side edge tabs (12, 13) extend obliquely down. These are located to bring about a clamping force against the asphalted roofing-board tracks at a suitable distance from the fixture's longitudinal central axis where the centrally located attachment hole (15) and attachment claws (14) are placed. Using the attachment claws (14), one can guarantee a an initial attachment for the fixture and appurtenant asphalted roof-boarding tracks and insulation, while the securing of the fixture to the false ceiling (20) is effected in a separate operation using the setscrew (17) and the expansion device (16).<IMAGE> |
