Wall block element

Abstract

A wall block element ( 1, 2, 3 ) for building and/or landscaping purposes, such as for building a retaining wall ( 4 ), masonry wall ( 5 ) and/or a curb. The wall block element ( 1, 2, 3 ) comprises a first panel ( 6 ) and a second panel ( 7 ), at least said first panel ( 6 ) being a natural stone slab. At least two spacer elements ( 8, 9 ) made of steel are arranged at a distance from each other for placing and adjoining the first panel ( 6 ) and the second panel ( 7 ) together in parallel and at a distance in relation to each other. An inner space ( 10 ) is defined by the panels in-between the panels in which inner space a filling material ( 11 ), such as cast concrete, can be placed, said spacer elements each having connecting means ( 12 ) to attach at least the first panel to the spacer elements.

1 . A wall block element wherein the wall block element comprises
 a first panel and a second panel, at least said first panel being a natural stone slab, and   one or more spacer elements made of metal for placing and adjoining the first panel and the second panel together in parallel and at a distance in relation to each other, and   an inner space being defined by the panels in-between the panels, in which inner space a filling material, such as cast concrete, can be placed, said spacer elements each having connecting means to attach at least the first panel to the spacer elements.   
     
     
         2 . The wall block element according to  claim 1 , wherein the connecting means comprise a connecting flange which is parallel to the surface of the panel to which the connecting flange is attached. 
     
     
         3 . The wall block element according to  claim 2 , wherein the connecting means comprise a glue joint by which the connecting flange is attached to the panel. 
     
     
         4 . The wall block element according to  claim 3 , wherein connecting means comprise a plurality of holes arranged at each connecting flange to enhance the grip of the glue joint. 
     
     
         5 . The wall block element according to  claim 1 , wherein the second panel is made of a sheet metal and is an integral structure with the spacer elements, said wall block element being for the retaining wall in which the second panel is against the soil and the first panel having an outer surface as a façade of the wall block element. 
     
     
         6 . The wall block element according to  claim 1 , wherein the second panel and the spacer elements are formed of a single sheet metal blank, the two spacer elements being bent from the ends of the second panel perpendicularly in relation to the plane of the second panel. 
     
     
         7 . The wall block element according to  claim 1 , wherein the second panel comprises an upper edge and a lower edge, said upper edge having an edge bend which is directed perpendicularly towards the first panel, and said lower edge having a receptable which opens to an opposite direction in relation to the direction of the edge bend, the receptable being adapted to receive inside the edge bend of another wall block element. 
     
     
         8 . The wall block element according to  claim 1 , wherein the first panel and the second panel are natural stone slabs, both of said natural stone slabs having a sawn inner surface which is towards the inner space and a treated outer surface. 
     
     
         9 . The wall block element according to  claim 8 , wherein the wall block element comprises two spacer elements which are separate from each other. 
     
     
         10 . The wall block element according to  claim 8 , wherein the first panel and the second panel have two end surfaces which are sawn surfaces, and that the spacer elements are connected with glue joints to said end surfaces. 
     
     
         11 . The wall block element according to  claim 9 , wherein the connecting means comprise connecting flanges which are bent perpendicularly from the sheet metal material of the spacer elements to be parallel with the inner surfaces of the panels, said connecting flanges being connected with glue joints to the sawn inner surfaces. 
     
     
         12 . The wall block element according to  claim 11 , wherein the spacer elements are placed into the inner space, the spacer elements being located at a distance from the end surfaces of the panels. 
     
     
         13 . The wall block element according to  claim 1 , wherein the spacer element comprises an upper edge having one or more notches, which are located at a distance below the upper surface of the panels, whereby a reinforcement bar can be placed on the support of the notches. 
     
     
         14 . The wall block element according to  claim 1 , wherein the spacer element comprises one or more holes to provide a path for the filling material, such as cast concrete. 
     
     
         15 . The wall block element according to  claim 1 , wherein the spacer element comprises a stiffening flange at the lower edge of the spacer element. 
     
     
         16 . The wall block element according to  claim 1 , wherein the stiffening flange is bent perpendicularly from the plane of the sheet metal material of the spacer element. 
     
     
         17 . The wall block element according to  claim 1 , wherein the thickness of the natural stone slab is 1 to 8 cm. 
     
     
         18 . The wall block element according to  claim 1 , wherein the wall block element has outer dimensions which are in conformity with the aggregate concrete masonry unit standards.
