Device for fastening facade elements of back-ventilated facade, has pointed-angular geometrical reference plane lying with respect to bar at specific angle and two spring devices that push outward facade components away from bar

摘要

The device has U-shaped metal profile rails with a transverse bar, two side strips and hooks (27, 28) that are open in a common direction for facade components (22-24) within a free end area of the strips, where the hooks lie on a same height. The strips stay parallel to each other and perpendicular to the bar. A hook groove (34) exhibits a greater distance from the bar than the hook (28). A pointed-angular geometrical reference plane (33) lies with respect to the bar at an angle below 5 degree. Two spring devices push outward the facade components away from the bar.
