Wall member

Abstract

A wall member ( 10 ) that may be used with similar constructed wall members to form a retaining wall or similar type of structure. The wall member ( 10 ) is at least partly formed of cast concrete and is transported to the location at which it is to be installed. The wall member ( 10 ) has an elongated base ( 11 ) from which there upwardly extends a wall portion ( 12 ). The member has end faces ( 13 ) between which one or more passages ( 17 ) extend provide for the ducting of services through the wall member ( 10 ).

1 . A portable wall member for installation at a desired location, the wall member having a generally horizontal length and a generally vertical height which is less than said length, with the length extending between end faces, said member including: 
 a cast concrete base extending longitudinally between the end faces and to rest on a supporting surface at said location;    a wall portion extending between the end faces and upwardly from said base to said height; and    at least one duct extending between said end faces to provide for services to extend through said member.    
     
     
         2 . The wall member of  claim 1  wherein said duct is provided in said base.  
     
     
         3 . The wall member of  claim 1  wherein said duct is located in said wall portion.  
     
     
         4 . The wall member of  claim 3  is a plurality of ducts extending between said faces.  
     
     
         5 . The wall member of  claim 4  wherein one of said ducts is adapted to provide for the ducting of water, with said wall member having an outlet for water longitudinally intermediate said faces.  
     
     
         6 . The wall member of  claim 4  wherein one of said ducts are provided for the ducting of electric cabling, and said member has an upwardly extending duct for the provision of a light to be connected to said cabling.  
     
     
         7 . The wall member of  claim 1  wherein said member has embedded in it a volume of material having a density less than the density of said concrete.  
     
     
         8 . The wall member of  claim 7  wherein said material is expanded plastics material.  
     
     
         9 . The wall member of  claim 8  wherein said material is expanded polystyrene.  
     
     
         10 . The wall member of  claim 3  wherein said wall portion is formed of cast concrete.  
     
     
         11 . The wall member of  claim 1  wherein said base and wall member are integrally cast from concrete.  
     
     
         12 . The wall member of  claim 1  wherein said wall portion is formed of cast concrete and is mounted on said base.  
     
     
         13 . The wall member of  claim 1  wherein said wall portion is formed of sheet material having longitudinal extremities attached to said base so as to co-operate therewith to provide a longitudinally extending hollow.  
     
     
         14 . The wall member of  claim 13  wherein said duct extends through said hollow.
