Definitions

  • the present invention relates to a device for retaining light and heavy vehicles along a taxiway. It has applications in the field of Civil Engineering and in particular the construction, maintenance or renovation of traffic lanes. It can, in particular, be implemented on an existing safety barrier to increase its restraining efficiency of both light and heavy vehicles.
  • a vehicle restraint device which comprises in the lower part a safety barrier to smooth and in the upper part an upper rail attached to the safety barrier.
  • the safety barrier comprises vertical hollow posts anchored in the ground and spacers bolted to the upper part of the posts, the low longitudinal rails, being fixed on the spacers, and the posts being metal profiles in C.
  • the upper rails are held above the safety barrier by bent rods introduced into the posts. Maintaining the upper rails on the rods is effected by fusible hooking (keying) and in case of impact, the high smooth (s) and the / rods separate.
  • the rods that are introduced into the posts can slide there especially in case of impact with a vehicle.
  • the contoured rod which is an omega section is difficult to achieve in a simple manner and requires cutting and welding to achieve the planned angulations.
  • the rod must be very rigid so that the fusible coupling can work in case of shock.
  • the rod will follow the movement of the safety barrier which bends and this rod thus forms an extension of the barrier which increases the width of the 'grip, also called deformation pocket, the device which bends backwards, besides said rod has been able to slide in the post, which further increases this grip.
  • the possible influence of the device after a shock is an important element to take into account during its installation and / or for compliance with standards.
  • the present invention proposes to remedy in particular the drawbacks mentioned with a light and heavy vehicle restraint device along a taxiway, the device comprising in the lower part a safety barrier at the rails and at the top a high retaining means mounted on the safety barrier, the safety barrier comprising vertical hollow posts anchored in the ground and spacers bolted to the upper part of the posts, the longitudinal rails being fixed to the spacers, the posts being C-shaped metal sections, high retaining means comprising rods on which are fixed by fixing means longitudinal retaining elements, the rods being introduced into the posts and slidable there particularly in case of impact with a vehicle.
  • the longitudinal retaining elements are fixed rigidly upwards of the rods in such a way that, in the event of impact with a vehicle, the rods remain integral with the retaining elements and the rod is a straight C-shaped metal section of which the resistance is such that in case of impact with a vehicle, the rod can bend under the action, on the one hand, down the rod, the folding of the pole of the security barrier leading to the rear and the floor and, on the other hand, towards the top of the rod, the longitudinal pulling effect of the longitudinal retaining elements tending to maintain said longitudinal retaining elements at their initial position, said folding of the rod and said fixing the rod allowing the final deformation front-rear (the front is on the side of the traffic lane and vehicles and the rear is the opposite to the device) of the restraint device in case of shock matches substantially u bending the post of the security fence.
  • FR 2 866 662 A1 in which a rigid rod bypassed and a fuse coupling between the upper arm and the rod are implemented, in case of impact, the rod disengages from the upper arm and undergoes substantially no bending. It follows that the stem of FR 2 866 662 A1 , always slipped into the post bent backwards, extends backward this one by realizing a rearward grip of the device much larger than in the case of the present invention.
  • the light and heavy vehicle restraint device 1 along a taxiway consists of two parts.
  • the safety barrier 2 comprises on the Figure 1 , a hollow post 5, typically of C100 metal profile, driven into the ground 4, a spacer 6 typically metallic and the smooth 7 typically metal double corrugation.
  • the spacer 6 is fixed to the post by bolting 11 and a height adjustment of the rail 7 + spacer 6 relative to the ground 4 is performed during tightening.
  • the posts are placed every 2 m approximately along the length of the device.
  • the retaining means 3 comprises on the Figure 1 a straight rod 8 with at its upper part a longitudinal retaining element 9 fixed thereto rigidly by a fixing means 10 comprising a stirrup.
  • a fixing means 10 comprising a stirrup.
  • the fixation of the retaining element on the rod is here not fusible but, on the contrary, is rigid and must resist during an impact, that is to say that the retaining element and the rod must remain in solidarity during a shock.
  • the rod 8, rectilinear, which is a metal profile typically C80 is inserted into the pole 5.
  • the rod 8 is made by folding a sheet.
  • the post and the rod are C-sections, they are in inverse position relative to each other so that the rod can pass beyond the bolting of the spreader + smooth on the pole .
  • a stop or locking tab 12 is made in the rod 8 at a certain distance from its lower end to block the descent of the rod 8 in the pole 5, the stop 12 abuts against the bolting 11. Because the distance between the stop 12 and the mounting of the fixing means 10 on the rod 8 is predetermined, the correct height arrangement of the retaining element 9 relative to the ground is driven by the correct arrangement of the rail 7 relative to the ground.
  • the rail 7 and the retaining element 9 are placed at heights such that they are respectively adapted to a light vehicle (thanks to the rail which is downwards from the device) and a heavy vehicle (thanks to the holding element which is upwardly of the device).
  • the rails are about 70 cm above the ground or the road and the retaining elements about 1 m to 1.10 m above the ground or roadway.
  • the retaining element 9 is further back than the smooth 7. It may be noted that the lower end of the rod does not go down to the ground / pavement level in the post. We will see Figure 2 this prevents the stem from being stuck in the post during an impact because the post tends to bend at ground level.
  • the safety barrier 2 may be de novo installed during the production of the device 1 of the invention or it is possible to use a safety barrier already in place to reinforce it by combining the retaining means 3.
  • the device of the invention is shocked by a vehicle and deforms.
  • the fence post is bent back and the ground (arrow a).
  • the retaining element by lateral pulling effect, tends to remain at its initial position or, at least, to move slightly, and, therefore, besides that the rod can slide in the post (arrow b ), there is a folding of the rod (arrow c) because the latter remains integral with the retaining element.
  • the retaining elements 9 In order to be able to remain substantially in place or, at the very least, to move slightly, in the event of impact, the retaining elements 9 must be secured to each other in a longitudinally resistant manner, along the device, so that the side pulling effect by the posts and rods placed on either side of the point of collision of the vehicle on the device and which do not directly suffer the shock, laterally hold said retaining elements. Thanks to the fact that the rod 8 can deform relatively easily in the event of impact and that the retaining element 9 does not separate from the rod 8, the deformation pocket thus remains limited. During the shock, the beam 7 and the spacer 6 are detached from the post because of the failure of the bolting 11. In other cases, the arm and the spacer can remain secured to the post.
  • Figures 2 and 3 are schematic because, in practice, other elements of the device can undergo deformations during an impact, including the retractor or the smooth, but to simplify the explanations only major deformations have been represented.
  • the device Due to its dynamic behavior in the event of impact, the device can meet the requirements of the standards relating to vehicle restraint systems.
  • the device of the invention makes it possible to retain both light vehicles and heavy vehicles.
  • the retaining element instead of being a single-wave rail with inwardly curved edges, may be a profile of any other suitable shape and, for example, a double-wave rail such as that of the barrier.
  • the rod may have a shape other than C and its thickness to be adapted to the shape in question to be deformed in case of impact.
  • all the parts of the device are metallic, hot-dip galvanized steel for example, in some variants of them can be made of wood such as for example in replacement of the metal bottom of the bottom, that of the barrier of security.
