Sealing device for facades and/or roofs

A roofs or facade assembly comprising:

• a plurality of supports each formed with a respective outer side;
• a respective inner sealing strip on the outer side;
• a pair of prefabricated individual surface-forming elements on said inner strip arranged edge to edge forming a gap to be sealed therebetween, each said of surface-forming elements being formed with a respective outer surface and an inner surface, the inner strip extending between the surface-forming elements and being in contact with said inner surfaces;
• a one-piece outer strip spaced from the inner strip and formed with:
• a pair of side walls tapering inwardly into the gap to be sealed,
• a respective strip flange extending laterally outwardly from each of the side walls and overlapping and contacting the outer surface of the respective surface-forming element adjacent the gap,
• a web in the gap bridging the side walls and forming a compartment therewith, and
• a respective inner lip on each of opposite edges of the web extending angularly outwardly towards and pressing against the respective edge of the pair of the ace-forming elements;
• a metal rail extending into said compartment and said gap and formed with:
• a pair of spaced apart rail flanges respective ones of the strip flanges and
• a pair of inwardly tapering legs extending into the compartment and connected with the respective rail flanges, the rail and the outer strip forming an outer seal for the gap;
• and
• a fastening bolt engaging the support and the rail and urging the inner and outer strips against the respective inner and outer surfaces of the surface-forming elements with the inner lips sealably pressed against the respective edges thereof upon tightening of the bolt and so that said elements can assume a variety of angles between them while being sealed at said gap.
