Longitudinal butt joint for fixing, to a substructure, sandwich like roof elements

摘要

The joint has one or more holder profiles (23), which are fitted on adjacent edge webs (5,6) of the roof elements (1a). Fixing screws (27) are screwed through the roof element in a sealed joint area and into a concave part (11) in the inner shell (4) of a sub-construction. The holder profiles are fixed on the edge webs along with the joint, and the holder profiles and screws are covered by one ore more cover strips (30). The holder elements are positively-fixed and screwed on the roof elements and have a middle web (24) and two clamp webs (25,26) folded outwards to pull together the roof elements and the fixing screws. The fixing screws screw the holder profile and both roof elements to the sub-construction of the roof.
