Definitions

  • the invention relates to the technical sector of the guardrails intended to be positioned along the roads to retain the vehicles in case of accident in particular.
  • a guardrail comprises at least one horizontal rail supported by vertical posts fixed in the ground.
  • the rails are assembled end to end by any known means and suitable to ensure perfect continuity at the junction areas.
  • guardrails there are metal guardrails and mixed wood / metal guardrails.
  • the invention relates more particularly to mixed safety rails wood / metal in which the smooth or are constituted by a log.
  • the present application relates to a guardrail of the type of that defined in the patent FR 2.833.630 which the applicant hereby also holds.
  • the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
  • the problem to be solved by the invention is to eliminate any risk of ejection of wood parts constituting the bar, to meet safety standards.
  • the metal rods are nails or staples.
  • the metal rods are screws.
  • the metal rods are introduced from the back of the log considered side of the fixing of the entire smooth with the posts.
  • the metal rods are introduced at the top and bottom of the log.
  • a road safety barrier comprises at least one horizontal rail (L) in the form of a wooden log (1).
  • the rail (L) is fixed on support elements or posts (P) fixed to the ground near the road to be equipped.
  • the rails are assembled end to end linearly and continuously.
  • the log (1) generally of circular section, has, over its entire length, a squared mortise (1a) formed parallel to its generatrices and from the rear side considered the outermost relative to the traffic lane, c that is to say on the side of the fixing of the entire smooth with the posts (P).
  • the mortise (1a) is intended to receive a stiffening support element (2), made of steel for example.
  • This stiffening element (2) has two parallel horizontal wings joined by a vertical wing positioned in support in the bottom of the mortise (1a).
  • the stiffening support elements (2) of two consecutive logs (1) are interconnected by a connecting sleeve (3) of complementary cross section to that of the stiffening element (2).
  • the butt jointing of two logs, in combination with the coupling sleeve (3) engaged at the opposite ends of two stiffening elements (2), is effected by means of assembly members (4).
  • assembly members (4) These provisions are not described in detail because they are well known to a person skilled in the art and emerge, for example, from the teaching of the aforementioned document FR 2.833.630 .
  • this embodiment of the smooth wood as such should not be considered as limiting. This is also the case with regard to the fixing arrangements between the rail (1) and the posts (P), in combination with the stiffening element (2) and / or the coupling sleeve (3).
  • each stringer (1) has, suitably distributed over its entire length, metal rods (5) able to prevent pieces of wood from the log being ejected under the effect of a shock usually caused by the vehicle that has just hit said log.
  • metal rods are introduced into the thickness of the log (1), angularly to its generatrices and from the back of the log (1) considered from the side from which is formed the mortise (1a), c that is to say on the side of the attachment of the entire smooth with the posts.
  • the metal rods (5) are introduced in the upper part and in the lower part on the log (1), being distributed over the entire length of the log (1) at regular intervals or not.
  • the rods (5) are inclined relative to a horizontal plane at an angle of between 20 and 40 degrees about. Advantageous results have been obtained when this angle is about 30 degrees.
  • the rods (5) can be made from elements known in the trade.
  • the rods (5) may be constituted by nails or screws.
  • they may have anchoring asperities of the type commonly used: twists, rings, ...
  • the rods (5) have a length of about 110 millimeters.
  • the rods (5) have a length of about 110 millimeters.
  • four nails at the top and four nails at the bottom are possible, under the conditions indicated above, four nails at the top and four nails at the bottom.
