Roof design

Abstract

A roof design has an external sheet covering ( 1 ), an insulating layer ( 3 ) provided beneath the sheet covering ( 1 ) and a load carrying structure ( 10 ) that supports the insulating layer ( 3 ). It is significant of the roof design that elements ( 7 ) for transporting an energy absorbing medium is provided in the insulating layer ( 3 ).

1 . Roof design that comprises an external sheet covering ( 1 ;  101 ), an insulating layer ( 3 ;  103 ) provided beneath the sheet covering ( 1 ;  101 ) and a load carrying structure ( 10 ;  110 ) that supports the insulating layer ( 3 ;  103 ), and that means ( 7 ;  107 ) for transporting an energy absorbing medium is provided in the insulating layer ( 3 ;  103 ), characterised in that the external sheet covering ( 1 ;  101 ) is corrugated, and that the surface of the insulating layer ( 3 ;  103 ) that faces towards the sheet covering ( 1 ;  101 ) has a shape that is adapted to the sheet covering ( 1 ;  101 ).  
   
   
       2 . Roof design according to  claim 1 , characterised in that the means for transporting an energy absorbing medium constitutes a flexible hose ( 7 ;  107 ).  
   
   
       3 . Roof design according to  claim 2 , characterised in that the insulating layer ( 3 ;  103 ) is equipped with a groove ( 9 ) for receiving the flexible hose ( 7 ;  107 ).  
   
   
       4 . Roof design according to  claim 3 , characterised in that the groove ( 9 ) is continuous and comprises straight portions and curved portions, seen in top view.  
   
   
       5 . Roof design according to  claim 1 , characterised in that sheet covering ( 1 ;  101 ) has a tile profile.  
   
   
       6 . Roof design according to  claim 3 , characterised in that the hose ( 7 ;  107 ) projects above the insulating layer ( 3 ;  103 ).  
   
   
       7 . Roof design according to  claim 4 , characterised in that the hose ( 7 ;  107 ) projects above the insulating layer ( 3 ;  103 ).
