VEHICLE SAFETY BARRIERS

摘要

A vehicle safety barrier comprises a length of rail supported by posts and, at the end of the rail, an anchor comprising first and second uprights and bracing therebetween, the anchor being oriented such that the line defined by the first and second uprights is at an acute angle to the line defined by the posts, and the rail extending past the first upright to a point of connection with the second upright. Angling the anchor to the direction of travel allows an impacting vehicle to be more smoothly deflected past the anchor. In another aspect, we disclose a vehicle safety barrier comprising a length of rail supported by posts and, at the end of the rail, an anchor comprising first and second uprights and bracing therebetween, the anchor being located behind the line defined by the posts. To assist in connecting the rail to the anchor, the end of the rail can be angled inwardly relative to the posts. To further protect impacting vehicles from the anchor, the rail can extend past the first upright to a point of connection with the second upright. We prefer that one of the uprights is provided with a bracket for attaching a barrier rail, the bracket comprising an attachment means for accepting the rail at an acute angle to the anchor and a spacer element between the rail and the anchor. Under an impact, the spacer element can therefore resist rotation of the rail about its point of attachment to the anchor. The spacer element is a hollow section such as a trapezoidal section. It is preferably located between the rail and the bracing. The attachment means (or part of it) can also extend between the spacer element and the rail, so that the spacer element is crushed between the attachment means and the bracing.
