Abstract:
A crash barrier for being arranged in the middle of a dual carriageway comprising:a plurality of elongate barrier elements which are arranged successively with their short sides directed towards each other, andan articulated connection which interconnects said plurality of barrier elements and which prevents lateral displacement of the interconnected short sides of neighboring barrier elements in relation to each other but permits force-absorbing deformation of the crash barrier by pivoting of the barrier elements relative to each other and limited longitudinal displacement of the barrier elements in relation to each other when a vehicle collides with the crash barrier when positioned for use,wherein each barrier element includes at least two protruding connecting elements from each short side, which are connected with corresponding connecting elements of a neighboring barrier element by a rod which is passed through holes in each connecting element,wherein, when said crash barrier is positioned for use, the connecting elements are displaceable to a limited extent between two end positions within a sleeve which is cast into the barrier element.
