Decking support system

Abstract

A decking support system including a plurality of decking support elements ( 30 ), engageable together to form a planar decking support surface suitable to receive decking, each decking support element ( 30 ) including sidewalls ( 50 ) extending in a longitudinal direction, a base, and an upper surface ( 90 ), the upper surface including a first surface for supporting decking and a second surface below the first surface including at least one fin ( 150 ) extending towards the first surface.

1 . A decking support system including:
 a plurality of decking support elements, engageable together to form a planar decking support surface suitable to receive decking;   each decking support element including:
 sidewalls extending in a longitudinal direction, 
 a base, and 
 an upper surface, the upper surface including a first surface for supporting decking and a second surface below the first surface including at least one fin extending towards the first surface. 
   
     
     
         2 . The decking support system of  claim 1 , wherein said at least one fin is a plurality of fins. 
     
     
         3 . The decking support system of  claim 1 , wherein said at least one fin includes a first end attached to said second surface, and a second end which extends towards but does not reach said first surface. 
     
     
         4 . The decking support system of  claim 3 , wherein said second end includes sloped surfaces. 
     
     
         5 . The decking support system of  claim 3 , wherein said second end is arrow-shaped. 
     
     
         6 . The decking support system of  claim 1 , wherein each said at least one fin is separated from at least one neighboring fin by a gap. 
     
     
         7 . The decking support system of  claim 1 , wherein said at least one fin extends in the direction of, and along the length of, said sidewalls. 
     
     
         8 . The decking support system of  claim 1 , wherein said decking support elements are made from aluminum. 
     
     
         9 . The decking support system of  claim 6 , wherein said adapted to receive a screw spike in said gap. 
     
     
         10 . A decking support element for a decking support system of  claim 1 .
