Foundation piles or similar load carrying elements

Abstract

A foundation pile has an innermost element, a structural tubular element surrounding the innermost element and composed of a non-metallic material, a tubular layer of a composite material surrounding the structural tubular element and connected with the later, and a friction coating applied on an outer surface of the layer of composite material.

1 . A foundation pile, comprising an innermost element; a structural tubular element surrounding said innermost element and composed of a non-metallic material; a tubular layer of a composite material surrounding said structural tubular element and connected therewith; and a friction coating applied on an outer surface of said layer of composite material.  
     
     
         2 . A foundation pile as defined in  claim 1 , wherein said structural tubular element is composed of a material selected from the group consisting of concrete, plastic, rubber and structural foam.  
     
     
         3 . A foundation pile as defined in  claim 1 , wherein said layer of composite material is composed of a material selected from the group consisting of fiberglass and carbon fiber.  
     
     
         4 . A foundation pile as defined in  claim 1 , wherein said layer of composite material is formed as a shell.  
     
     
         5 . A foundation pile as defined in  claim 1 , wherein said layer of composite material is composed of a plurality of individual layers.  
     
     
         6 . A foundation pile as defined in  claim 1 , wherein said layer of composite material includes metal components intended for oxidation after placement of a pile in a medium.  
     
     
         7 . A foundation pile as defined in  claim 1;  and further comprising a friction layer located between said hollow conduit and said structural tubular element.  
     
     
         8 . A foundation pile as defined in  claim 1;  and further comprising a layer of a connecting material provided between said structural tubular element and said layer of a composite material.  
     
     
         9 . A foundation pile as defined in  claim 8 , wherein said connecting layer is composed of resin.  
     
     
         10 . A foundation pile as defined in  claim 1;  and further comprising a connecting layer provided between said layer of composite material and said friction coating.  
     
     
         11 . A foundation pile as defined in  claim 10 , wherein said connecting layer is composed of resin.  
     
     
         12 . A foundation pile as defined in  claim 1 , wherein said innermost element forms a hollow conduit.  
     
     
         13 . A foundation pile as defined in  claim 11 , wherein said hollow conduit is filled with a filler material.  
     
     
         14 . A foundation pile as defined in  claim 11 , wherein said innermost element is solid.
