Definitions

  • the invention relates to the technical sector of track safety road or motorway traffic.
  • the invention relates to a security barrier equipped with a protective screen.
  • a crash barrier for roads or highways basically includes at minus a stringer attached to the top of the posts via elements acting as a retractor.
  • the beams have a transverse profile substantially in the shape of an omega.
  • this type of safety barrier To increase the safety of motorcyclists in particular, it has been proposed to equip this type of safety barrier with a safety screen arranged at the bottom of the slide assembly. According to the standards in force, this protective screen is determined to provide a more important in contact with the body of the injured cyclist, with the objective allow its sliding in order to evacuate the energy of the shock. This screen should have some amortization capacity.
  • the object of the invention is to remedy these drawbacks of simple, safe, efficient and rational way.
  • the problem which the invention proposes to solve is to increase the damping effect in the event of an impact on the protective screen, in looking for a progressive penetration effect of the screen towards the post and no longer a simple tilting effect towards said post.
  • a device for fixing a protective screen for crash barriers traffic lane which comprises support members each having a support part capable of being fixed on the post, said part being extended by an elastically deformable zone by acting energy absorber, said zone having arrangements for securing the screen in a substantially vertical plane, set back of the vertical plane defined by the beam.
  • the free end of the elastically deformable zone has support and centering arrangements with the post.
  • the elastically deformable zone has a rectilinear central part arranged for fixing the screen, said part being extended symmetrically, on either side, by two rectilinear segments arranged angularly to act as a shock absorber, said segments being connected to the support parts with the post.
  • the support and fixing part of the support member has arrangements to be fixed in combination with the spacer assembly (s) at the top of the post. These arrangements are constituted by an oblong light in communication with a transverse through light for the engagement of the assembly member (s).
  • the support arrangements and centering the free end of the deformable zone with the support consist of two squared legs capable of enclosing the section of the post.
  • the screen consists of one or more several hollow and raised ribs formed longitudinally on its the entire length, the hollow ribs having openings for the passage of assembly members with the central fixing part of the deformable area of the support member.
  • the ribs are of section trapezoidal. As a result, the shape of the ribs contributes to the effect amortization sought.
  • the safety barrier presents generally at least one top rail (L) fixed on different posts (P) via spacers (E).
  • the beams (L), the spacers (E) and the posts (P) are made of metal, for example galvanized steel.
  • the retractors are fixed to the upper end of the posts (P) by means of bolts (B), while the rails (L) are fixed to the end of the spacers (E) at means of bolts (B1).
  • the end of the heddles (L) has arrangements for coupling in alignment position of several rails fixed along the traffic lane to be fitted.
  • the aim sought after according to the invention is to equip the safety barrier with a protective screen (1) to prevent in particular motorcyclists, in the event of an accident and in the event of impacts or slips, to come to be embedded in the level in particular of the posts.
  • a protective screen (1) to prevent in particular motorcyclists, in the event of an accident and in the event of impacts or slips, to come to be embedded in the level in particular of the posts.
  • the screen of protection (1) is fixed relative to the slide (L) by means of a device able to act as an energy absorber in the event of impact.
  • the fixing device according to the invention comprises, for each boom, support members (2) in corresponding numbers advantageously, but not limitatively, to the number of posts or spacers.
  • the support members (2) have a support part (A) capable of being fixed to the post (P) as indicated in the following description.
  • This part (A) is extended by an elastically deformable zone (D) in acting as an energy absorber.
  • This area (D) also presents arrangements for securing the screen (1) under the conditions indicated above, that is to say in a substantially vertical plane at removal of the vertical plane defined by the top rail (L).
  • each of the support members (2) is produced from a flat iron, of constant width and suitably folded to constitute the fixing zone (A), the zone acting as a shock absorber (D) and a zone (C) for positioning and centering with respect to the part bottom of post (B).
  • Zone (D) has a rectilinear central part (2a) arranged for the fixing the screen (1).
  • the straight central part (2a) has an oblong lumen (2a1) for organ engagement assembly (3) of the bolt type for example.
  • This central part (2a1) is extended symmetrically on both sides by two segments rectilinear (2b) and (2c) arranged angularly to act shock absorbers.
  • the segments (2c) are connected to support parts (2d) and (2e) able to be arranged face to face against the corresponding post (P).
  • the upper support part (2d) has an oblong opening (2d1) in communication with a through transverse opening (2d2) for the engagement of the assembly member (s) (B) of the spacer (E) on the post (P).
  • the lower support part (2e) has two squared lateral tabs (2e1) capable of enclosing the section of the post, thus ensuring the centering of the whole of the support member (1). Given the light (2d1), it is possible to easily adjust the height of the support member (1) relative to the posts, to modify, concomitantly, the positioning of the screen (1).
  • Figure 3 shows a positioning considered normal for the screen.
  • Figure 4 shows a positioning of the screen to avoid an obstacle to the ground, while Figure 5 shows a setting in the lower position of the screen.
  • the screen (1) is constituted by several hollow ribs (1a) and in relief (1b) formed longitudinally over its entire length.
  • the hollow ribs (1a) have openings for the passage of the assembly members (3).
  • the ribs (1a) and (1b) are of substantially trapezoidal section. It follows that after the assembly members (3) have been put in place, the latter do not protrude from the raised ribs (1b). Under these conditions, no part is protruding.
  • the covering part of one end of the screen (1) is of reduced dimensions, resulting from a deformation on the whole of its height.
  • the recessed and raised grooves contribute to good resistance of the entire screen and gives it better elasticity as indicated.
