Wire netting for containment and reinforcement structures

Abstract

Wire netting for containment and reinforcement structures, which netting comprises one or more strengthening bars extending in a preferential longitudinal direction. The strengthening bar comprises a series of notches distributed over at least a portion of its peripheral curved surface in the preferential longitudinal direction, so that it remains securely accommodated inside the meshes of the netting when the netting is subjected to repeated and varying tensile forces.

1 . Wire netting for containment and reinforcement structures, which netting comprises at least one strengthening bar ( 6 ) extending in a preferential longitudinal direction, characterised in that the at least one strengthening bar ( 6 ) comprises a series of notches ( 10 ) distributed over at least a portion of its peripheral curved surface in the preferential longitudinal direction.  
     
     
         2 . Wire netting according to  claim 1 , characterised in that the notches ( 10 ) distributed over the peripheral curved surface of the strengthening bar ( 6 ) are interrupted by flattened portions ( 11 ) defining at least two paths ( 14 ) extending in a helix on the peripheral curved surface.  
     
     
         3 . Wire netting according to  claim 2 , characterised in that the notches ( 10 ) distributed over the peripheral curved surface of the strengthening bar ( 6 ) have a spacing equal to or less than the spacing of the paths ( 14 ) defined by the flattened portions ( 11 ).  
     
     
         4 . Wire netting according to  claim 3 , characterised in that the notches ( 10 ) are distributed over the peripheral curved surface of the strengthening bar ( 6 ) in such a manner that the flattened portions ( 11 ) define at least one path ( 14 ) having a helical direction opposing the direction of the remaining paths ( 14 ).  
     
     
         5 . Wire netting according to  claim 1 , characterised in that the notches ( 10 ) distributed over the peripheral curved surface of the strengthening bar ( 6 ) are interrupted by flattened portions ( 11 ) defining at least three paths extending in a rectilinear manner on the peripheral curved surface.  
     
     
         6 . Wire netting according to  claim 5 , characterised in that the at least three paths extending in a rectilinear manner are arranged diametrically non-opposite relative to the longitudinal axis of the strengthening bar ( 6 ).  
     
     
         7 . Wire netting according to  claim 1 , characterised in that the notches ( 10 ) distributed over the peripheral curved surface of the strengthening bar ( 6 ) are interrupted by flattened portions ( 11 ) defining at least two paths ( 14 ) extending in a curvilinear manner on the peripheral curved surface.  
     
     
         8 . Wire netting according to  claim 1 , characterised in that the strengthening bar ( 6 ) comprises a central core ( 8 ) having a substantially cylindrical cross-section.  
     
     
         9 . Wire netting according to any one of the preceding claims, characterised in that it comprises double-twist or triple-twist meshes ( 4 ), each bar ( 6 ) being accommodated inside the meshes ( 4 ).  
     
     
         10 . Wire netting according to  claim 9 , characterised in that each bar ( 6 ) is inserted into intertwined portions ( 12 ) of the meshes ( 4 ).  
     
     
         11 . Use of a strengthening bar for strengthening wire netting, characterised in that the wire netting ( 2 ) is defined by any one of  claims 1  to  10 .  
     
     
         12 . Use of a strengthening bar according to  claim 11 , characterised in that, during the manufacture of the netting ( 2 ), the bar ( 6 ) is accommodated in the intertwined portions ( 12 ) of the meshes ( 14 ).  
     
     
         13 . Use of a strengthening bar according to  claim 11 , characterised in that, after the manufacture of the netting ( 2 ), the bar ( 6 ) is accommodated between the meshes ( 14 ).
