Roof Fixing Assembly

Abstract

A roof assembly ( 10 ) including a plurality of beams ( 11 ) to which there is fixed mounting brackets ( 12 ). The brackets ( 12 ) attach roof sheeting ( 15 ) that extends generally transverse of the beams ( 11 ). Clips ( 24 ) are provided to aid in fixing the sheets ( 11 ) to the brackets ( 12 ). The clips ( 24 ) inhibit separation of the sheets ( 15 ) thereby increasing the load at which the assembly ( 10 ) will fail.

1 . A roof assembly including: a plurality of elongated roof sheets that are arranged with overlapping edge portions that secure adjacent sheets together, each sheet including a longitudinally extending pan located between longitudinally extending flanges, each flange extending upwardly away from the adjacent pan to a longitudinally extending extremity, with adjacent extremities of adjacent sheets providing the overlapping edge portions, and wherein each extremity includes a longitudinally extending hollow section, with engaged overlapping portions including one hollow section being located within the hollow section of the associated overlapping edge portion so as to secure adjacent sheets together; a plurality of mounting brackets, each mounting bracket projecting inwardly of the hollow sections so as to be captively located with respect thereto; and a plurality of clips, the clips each encompassing a length of the overlapping edge portions so as to inhibit separation thereof with respect to the mounting brackets. 
   
   
       2 . The roof assembly of  claim 1 , wherein the coupling is a “dove-tail” coupling. 
   
   
       3 . The roof assembly of  claim 1 , wherein said sheets are formed of metal or metal alloy sheeting. 
   
   
       4 . The roof assembly of  claim 1 , wherein each clip has a longitudinal hollow of a corresponding cross-section to the hollow sections. 
   
   
       5 . The roof assembly of  claim 1 , wherein each mounting flange includes a longitudinally extending head that is captively located within the hollow sections. 
   
   
       6 . The roof assembly of  claim 1 , wherein each clip engages the flanges of this overlapping portion so as to inhibit separation of the flanges at said overlapping portions.
