Description

[0001] The present invention relates to the area of ​​fastening steel truss ceiling panels, in particular a fastening device for steel truss ceiling panels.

[0002] Steel truss ceiling panels have been further developed based on profiled ceiling elements. The steel trusses are manufactured in-house according to specific type requirements and can be produced in prefabricated lengths. Using sheet metal welding techniques, silanization, pure manganese phosphating, rinsing and drying processes, as well as other rust removal and rust protection techniques, the elements are protected against corrosion and sealed with a wrapped protective film. On site, the truss ceiling elements must first be positioned correctly, the reinforcement welded, then dowel bolts welded on, and finally the on-site reinforcement installed and tied. After customer acceptance, the concrete is poured.
