A security barrier (10) comprises a first fence (20) and a second fence (40). The first fence comprises a first series of posts (22) and the second fence comprises a second series of posts (42). The first and second fences are provided adjacent to each other with the first fence being coupled below ground level with a the second fence. A footing having first and second post sockets is also provided for receiving a first post from each of the first and second fences respectively.
A retainer (10a, 10b, 10c) for a wire rope road safety barrier, comprising a plurality of posts (14), is provided for supporting one or more wire ropes (12) above the ground. The retainer comprises an arm (16a, 16b) for embracing at least half of a circumference of the post whereby the retainer can be held on the post at a position along its length. The retainer also comprises a frangible or yieldable tab (18) extending from the arm for retaining the wire rope against the post.

After deflecting a vehicle, the rope of a conventional wire rope road safety barrier can detach and result in an undesirable shock wave. The present invention provides a post that attenuates travel of the shock wave of the rope along the road safety barrier. The inventive post includes a cut-out, a flat portion extending transversely to the longitudinal axis of the post and a curved portion extending from a flat portion that is innermost relative to the outer periphery of the post to the outer periphery. The substantially flat portion resists downward movement of the rope during vehicle impact whereas the curved portion permits upward movement thereof.
A road safety barrier having a plurality of ropes supported by posts rigidly mounted on or in the ground is described. Each rope is held in tension against the posts and supported in a longitudinally oriented indentation in a side of the posts. The ropes are released from a post and the post is not pulled from the ground when a vertical force is exerted on the rope. The post may have a circular cross-section and the indentation has a bottom oriented substantially parallel to the ground such that the rope is biased to exit upward out of the indentation. The ropes when weaved are tensioned against the posts and this gives rise to a combined frictional resistance to displacement of the ropes relative to each post along the length of the safety barrier.

The invention relates to a support structure for use in supporting a road sign or the like. A longitudinal tubular support member has a uniform cross-section that includes a plurality of circular or part-circular port sections for receiving an end anchorage. Enclosing wall sections extend between the port sections and are shaped to include a concave form so as to promote inward collapsing of the support member in the event of an impact to the support structure.
A road safety fence post (1) for supporting a longitudinal restraining member, such as a wire rope (10) is described. The post (1) comprises a longitudinal axis X and a cross-sectional profile in a plane Y-Z perpendicular to the longitudinal axis that presents at least two points of contact (6, 8) for the longitudinal restraining member on one side of the post. The post (10) is formed from a material profiled about the longitudinal axis such that the two points of contact (6, 8) are defined by first and second inflections (3, 5) in the surface of the material that face in one direction. The first and second inflections are joined by a section (7) of the material that defines a third inflection facing in an opposite direction to the first and second inflections (3, 5).
A post (1) is provided for use in a road safety fence. The post comprises a receiving means (13, 30), e.g. a slot or notch, for accommodating a wire rope or cable (5, 7, 9, 11). The slot has an open end (15) for receiving the rope. A yieldable restraint (17, 19, 27, 29, 32) is provided at or near the slot opening for resisting exit of the wire rope therefrom when a vehicle impacts the post or the fence. A road safety fence incorporating one or more such posts, and a method of forming the same, is also provided.
d is supported between the end posts and optionally woven around the intermediate posts, the ropes being secured at each end to respective end posts. Energy absorption means 21 is provided at each end for absorbing energy transmitted by the ropes from the impacting vehicle.
A crash barrier beam (10) suitable for temporary placement on a road comprises a housing (18) which, in profile, has a laterally extending base (12) for contact with the road. The beam has a narrower central element (14) upwardly extending from the base that terminates in a top portion (16). The exterior of the housing provides a continuous impact surface to an oncoming vehicle and the profile provides stability to the beam on impact. The crash barrier beam (10) has a length defined by a first end (24) and a second end (26, 28). At least one of the first and second ends comprises formations (32, 34) for engagement with corresponding formations (38, 40) on an end of an adjacent beam (10′) so as to facilitate joining of the beams to one another. The formations are configured for the beams to be substantially self-aligning with respect to each other.
A perimeter security barrier (1) for restraining a vehicle impacting the barrier from a direction substantially perpendicular thereto is described. The barrier comprises a pair of spaced apart end posts (3, 5) rigidly fixed in the ground and intermediate posts (11a, 11c.....) disposed between the end posts are also fixed in the ground. At least one pair of wire ropes (15c, 15d) is supported between the end posts and optionally woven around the intermediate posts, the ropes being secured at each end to respective end posts. Energy absorption means (21) is provided at each end for absorbing energy transmitted by the ropes from the impacting vehicle.
