Insulating metal double skinned hangar profile roof - has upper skin sliding above lower one to compensate for heat expansion

摘要

Spacing components separate an upper and a lower shell made of profile sheet metal plates, to provide a space for heat and/or sound insulation and a ventilation area, in a profile roof for laying on a substructure, esp. in a hangar- type building. The upper shell (4) is mounted on the lower one (1) so as to be displaceable, providing compensation for expansion effects lengthways and crossways. Use can be made of spaced sliding connections (10), with play in the upper profiles lengthways and crossways directions, to limit the upper shells movement and to support it on the lower shell. There is pref. greater play lengthways. This successively combats heat expansion and shrinkage, and provides adequate stability under wind loading.
