A heavy-duty barrier

Abstract

A heavy-duty barrier, which is movable, comprising a base part, which comprises a ballast, and a fence part attached to the base part. The fence part comprises a fixed bar structure and a rigid connection element, which is movably attached to the bar structure, and which is connectable with a corresponding connection element of a neighboring heavy-duty barrier. The connection element comprises an attachment portion moveably attached to a bar portion of the bar structure, and a hook portion arranged to be engaged with a corresponding hook portion of another connection element.

1 . A heavy-duty, movable barrier, comprising a base part, which comprises a ballast, and a fence part attached to the base part, wherein the fence part comprises a fixed bar structure and a rigid connection element, which is movably attached to the bar structure, and which is connectable with a corresponding connection element of a neighboring heavy-duty barrier, wherein the connection element comprises an attachment portion movably attached to a bar portion of the bar structure, and a hook portion arranged to be engaged with a corresponding hook portion of another connection element. 
     
     
         2 . The heavy-duty barrier according to  claim 1 , wherein the movable attachment of the attachment portion includes rotation of the connection element about a longitudinal centre axis of the bar portion. 
     
     
         3 . The heavy-duty barrier according to  claim 1 , wherein the movable attachment of the attachment portion includes movement along a length of the bar portion. 
     
     
         4 . The heavy-duty barrier according to  claim 1 , wherein the attachment portion is tubular and encircles the bar portion. 
     
     
         5 . The heavy-duty barrier according to  claim 1 , wherein the hook portion comprises a first protrusion protruding from the attachment portion, and a second protrusion protruding from the attachment portion, wherein the first and second protrusion define a gap between them, which gap is arranged to receive a part of a first protrusion of another connection element. 
     
     
         6 . The heavy-duty barrier according to  claim 5 , wherein the first protrusion has an L-shaped cross-section, wherein a free end of the first protrusion faces the second protrusion. 
     
     
         7 . The heavy-duty barrier according to  claim 1 , wherein the base part is made of concrete or is concrete fillable.
