Cable-barriers
A terminal post for a cable barrier which is of a unitary post construction. The integrally formed post has a cable barrier portion for retaining barrier cable(s) and an anchor-cable portion for retaining anchor cable(s). The cable barrier includes at least one cable-barrier portion which, in use, receives and retains one or more barrier-cables used in the cable barrier and at least one anchor-cable portion in the form of a central groove, which, in use, receives and retains one or more anchor-cables which are anchored so as to counter balance the force applied to the terminal post by the barrier-cable(s). The cable-barrier portion(s) and the anchor-barrier portion(s) within the post body are configured so that, in use, at least one of the anchor-cable(s) and barrier-cable(s) are releasable from the body during a collision with a vehicle where the anchor-cables act as a ramp and/or snag during the collision.
1. A terminal post having a top section which is of one piece construction which allows for direct transfer of load from anchor cable(s) to a cable barrier, and allows release of the anchor cable(s) at a height above ground level, said post having a body which substantially resembles an inverted V-shape, wherein the body comprises:
a region underneath an apex and between inclined arms forming the V-shape, said region configured as a slot for receiving and retaining the anchor cable(s) to form an anchor-portion; and
outer sides of the inclined arms proximate the apex, include channels, which are upwardly inclined with respect to the horizontal, for receiving and retaining, in use, barrier-cable(s) to form a cable-portion.
2. A cable barrier which includes a terminal post as claimed in claim 1 .
