Definitions

  • the present invention relates to a wedge intended for mounting on a post of a safety barrier fitted to a road traffic lane.
  • a safety barrier is a profiled element arranged parallel to the ground, and fixed on the latter by means of regularly spaced vertical posts which are sealed to the ground.
  • the mounting of the slide on the head of the posts is not carried out directly, but with the interposition of a block.
  • the function of this wedge is first of all to move the slide away from the post in order to avoid or reduce the risks of embedding a vehicle in a post, in the event of an accident.
  • the primary purpose is therefore to allow a vehicle to lean against the slide, or even to exert an action thereon in the direction of the post, without the vehicle hooking the post, for example using the one of its wheels.
  • metal shims having a shape specially designed to resist crushing, thus ensuring an integral transmission of the force resulting from the impact of the vehicle against the slide, towards the support which bends at its base, thus forming a shock absorber itself, the slide being kept away from the support.
  • the slide thus released from the support can pivot on its fixing point, which is also its fulcrum, and remain vertical, although the support bends and tilts under the action of the force resulting from the shock.
  • the slide pushed by the vehicle, moves back along a substantially horizontal trajectory, although it is held by the support.
  • the non-compressible wedge is driven towards the ground by the support on which it is bolted, while the slide moves back horizontally, although it is fixed on the wedge by another bolt.
  • the vehicle which deforms the slide comes to be embedded therein which ensures its retention, this retention being favored by the fact that the slide can continue to deform without being pulled to the ground. Indeed, if the slide was pulled towards the ground by the support posts, the vehicle could easily cross it, and leave the lane with the risk that there is to strike a hard point, or to make a fall off the road.
  • the wedges currently used are mechanically welded parts, comprising two main stirrup-shaped parts, which are assembled to one another.
  • the first part which is intended to be fixed on the support post consists of a bracket with a vertical axis.
  • the second part which is intended to be fixed by the slide is constituted by a horizontal opening stirrup, the free ends of the wings of which are fitted inside the first stirrup, these two wings being divergent, and s' spreading from the central fixing part on the slide, towards the central part of the other bracket intended for fixing on the support post.
  • the two wings of the second stirrup-shaped part are symmetrical with respect to a horizontal plane.
  • wedges of this type have economic disadvantages, since it involves making two separate parts which are joined to one another by welding. In addition, these parts are not stackable, are stored and delivered in bulk, so that a certain number of them is always lost during the various handling phases. Finally, these wedges are heavy, and access to the bolts is difficult, which increases the intervention time during installation.
  • the object of the invention is to remedy these drawbacks by providing a wedge for mounting a safety barrier on a support post having excellent crushing resistance, allowing "unbuttoning" of the wedge with respect to - screw of the support post, when the slide has moved back towards the outside of the roadway by a value greater than a predetermined value under the action of an impact, likely to be lighter, easier to manufacture, more practical packing than traditional holds, and avoiding the retention of snow, ice or humidity.
  • the wedge which it concerns is constituted by a tubular piece of vertical opening comprising two parallel walls intended respectively for the support and for the fixing on a support post and on a safety barrier connected by two wings. diverge from the fixing wall on the post towards the fixing wall on the slide, reinforcement means being provided to ensure resistance to crushing.
  • This structure makes it possible to obtain a piece that is significantly lighter than traditional wedges, at a lower cost price, eliminating any bearing surface for retaining snow or ice, allowing the flow of water and protective liquids. pavements, and offering the possibility of receiving, placed vertically inside the arch, a post or similar for use as temporary signage.
  • this wedge in the mounted position of this wedge, its upper edge is situated in a plane substantially perpendicular to the axis of the support post and its lower edge is inclined from bottom to top and from the support post towards the slide, the wall of the shim intended for attachment to the support post having a hole for the passage of a bolt, formed near the horizontal upper edge.
  • this wedge is asymmetrical, since its upper edge is horizontal and its lower edge is inclined. It should be noted that the fact that the upper edge is horizontal does not in any way affect the resistance of the shim, since it is the part of the latter which is located below the fixing hole on the support post. which plays an active role during the deformation of the assembly under the impact of a vehicle.
  • this asymmetrical shape of the wedge allows, during storage and transport of the wedges, to arrange them head to tail, which facilitates packing in a parallelepiped form.
  • the reinforcing means ensuring the resistance to crushing consist of horizontal ribs formed at least in the two wings connecting the fixing walls respectively on the support post and on the slide.
  • the reinforcing means ensuring the resistance to crushing consist of a flat iron connecting the two wings forming legs, and extending over part of the depth of the wedge.
  • the ribs can also be used, insofar as they are provided on the walls bearing against the support post and against the slide, to ensure a locking in rotation of the fixing nuts.
  • This wedge can be made from a single element which is folded back on itself and closed by welding, or on the contrary can be obtained from two elements, at least one of which forms an arch, the free ends of which are connected by the other element, fixed on the first by welding.
  • FIG. 1 shows a safety barrier 2 constituted in a known manner by a longitudinally ribbed profile.
  • This safety barrier is intended to be fixed on vertical posts 3 fixed to the ground at a determined distance from each other.
  • the fixing of the slide on each post 3 is carried out with the interposition of shims 4.
  • Each shim is constituted by a tubular part having a vertical opening 5. This part comprises a wall 6 for support and fixing against a post 3, as well as a wall 7 for supporting and fixing the slide 2.
  • the upper edge 8 of the wedge 4 is located in a plane substantially perpendicular to the axis of the support post, while its lower edge 9 is inclined from bottom to top and of the support post 3 towards the slide 2.
  • the wall 6 intended for fixing to the support post 3 has a hole 10 for the passage of a bolt 12, located near the horizontal upper edge 8.
  • the wall 7 has three holes 13 arranged according to a horizontal line for fixing the slide by means of bolts 14.
  • the wedge 4 has several horizontal ribs 15, in this case three series of ribs offset vertically with respect to each other, given by way of example.
  • These ribs aim to provide sufficient rigidity to the wedge 4 to prevent it from being crushed under the effect of an impact exerted by a vehicle against the slide 2.
  • the shim is produced from a single folded metal part, and closed on itself by a weld 16.
  • the shape of the wedges 4 allows, as shown in Figure 4, their head to tail storage, which facilitates this storage as well as packing for shipping to the site.
  • the invention brings a great improvement to the existing technique by providing a piece forming a shim of exceptional rigidity, at a moderate cost price, offering great simplicity of storage and packaging, as well that a very simple implementation given the ease of access to the fixing bolt on the support posts and on the rails.
  • the component part of the wedge could be made in two parts, for example of U-shaped section assembled to each other by welding, or that the stiffening of the part could be obtained by example by a flat connecting the two wings of the jamb, and / or a folded edge on the walls 6 and 7, without departing from the scope of the invention.
