Definitions

  • the present invention relates to a highway guard rail assembly wherein the guard rail comprises hollow mounting posts of a suitable plastic material with a guard rail bar, preferably of metal, extending from post to post and attached to the posts.
  • Guard rails are split into classes. Which classes the public roads authorities choose to use depends upon along which roads they are to be mounted, what type of vehicles use the roads, the permitted speed limits on the roads and the geographical conditions along the roads.
  • guard rails are approved by the public roads authorities in the respective countries based on standard full-scale collision tests at approved laboratories in Europe.
  • the posts used are chiefly wooden posts, which are essentially round in Norway, whilst in Canada they have a rectangular cross-section.
  • the primary purpose of a highway guard rail is to prevent personal injury by preventing vehicles from driving off the road.
  • the guard rail In the event of an impact, the guard rail is to bring the car back on to the road with minimum damage to the car and minimum injury to the driver and passengers. This is achieved by the guard rail yielding slightly on collision so that the speed of the car is reduced, and then the car is guided back on to the road. In the event of an impact, the guard rail must not give way so much that the car drives into the roadside ditch, down a slope or over a drop.
  • guard rail should not be pulled down towards the ground when the posts are bent, as this would cause the car to drive over the guard rail with catastrophic consequences.
  • the guard rail must not be so yieldingly elastic that it throws the vehicle too far out into the road after a collision with the danger of meeting traffic oncoming traffic.
  • the guard rail must have a property and mode of action such that it gives a simultaneous speed reduction on buckling, friction with the guard rail bar and moderate bending of the posts so that the load (deceleration) for driver and passenger is not too great.
  • guard rail should be simple to mount and in given cases also simple to repair.
  • An important aspect is service life before replacement must be planned.
  • the present invention thus relates to a highway guard rail assembly
  • a highway guard rail assembly comprising hollow mounting posts of a suitable plastic material and a guard rail bar of metal extending from post to post and attached to the posts, wherein the bar is fastened to the post by bolts and associated nuts, wherein the bolt runs through only one or both walls of the post
  • this assembly is characterised in that the bolt hole in the bar is reinforced with a washer or the like between the nut (the head) and the bar whilst the bolt hole (holes) in the post walls have a diameter greater than the diameter of the bolt, but slightly smaller than the diameter of the bolt head (the nut), the bolt head (the nut) resting directly against the post wall.
  • the present invention thus describes a fastening system for the fastening between post and guard rail bar which makes it possible to achieve a collision progression which, as has been found in tests at an approved Swedish traffic laboratory, is considerably more favourable as regards most of the aforementioned requirements set in the CEN standards, now Norwegian Standard NS-EN 1319-1, than is achieved with conventional wooden or steel posts.
  • Figure 1 shows the fastening of a guard rail bar to a post in a preferred embodiment
  • Figure 2 shows the fastening of a guard rail bar to a post in an alternative embodiment.
  • the guard rail bar 2 is secured to the post 1 by means of a bolt 3 which passes through the guard rail bar 2 and the nearest wall 5' of the post 1.
  • the bolt head 8 is on the road side of the bar 2 whilst the corresponding nut 4 is inside the hollow post.
  • the bolt may be inserted the other way around so that the head 8 is inside the post 1 and the nut 4 is on the outside.
  • An adjusting washer is placed between the head 8 (or the nut 4), whilst there is no such adjusting washing between the nut 4 (the head 8) and the wall 5' of the post 1.
  • the wall 1 in the area for the bolt is "weakened" in that the bolt hole 7 has a larger diameter than the bolt 3.
  • the hole 7 in the wall 5' must not be so great that the bolt 4 (the head 8) does not span across it to ensure that sufficient fastening under normal stresses is obtained.
  • the bolt 3 runs through the whole post 1, that is to say, through the wall 5' (as in Figure 1) and also the wall 5".
  • the same considerations also apply here as regards the dimensioning of the bolt hole 7 in relation to the nut 4 (the head 8).
  • an adjusting washer 6 is positioned as reinforcement between the head 8 (the nut 4) and the bar 2 and the mode of action is otherwise as described below.
  • the post 1 per se does not constitute an obstacle, it will be bent elastically under the car, but the bar 2 will act as a band which intercepts the car and leads it back to the carriageway.
  • plastic posts are a very environmentally friendly product, are easy to maintain, have a very long service life and can be recycled, all of which are considerable advantages over the previously used posts of impregnated wood or galvanised metal.
  • hollow plastic posts without any form of internal ribbed reinforcements or the like. It has also been found that hollow posts which are "run over" by a car will straighten up and in fact recover a considerable part of their original strength so that immediately after a collision they will, if nothing else, function as an optical obstacle for subsequent cars, can serve as a point of attachment for warning tapes which may be hung up, and serve as a new point of attachment for a preliminary repair in those cases where a more extensive repair must be delayed for various reasons.
  • plastic posts have a certain degree of flexibility and will return to their original shape after the snow plough has driven past.

Abstract

L'invention concerne un ensemble pour glissière de sécurité d'autoroute, constitué de montants (1) en matière plastique appropriée, une barre de glissière métallique (2) s'étendant d'un montant à l'autre et étant fixée à ces derniers. La barre (2) est fixée au montant (1) au moyen de boulons (3) à écrous associés (4), le boulon (5) s'étendant seulement à travers la partie du montant (1) reposant contre la barre (2). Par ailleurs l'orifice (5) à boulon dans la barre (2) est renforcé par une rondelle (6) placée entre l'écrou (4), la tête (8) et la barre, alors que l'orifice (7) à boulon dans le montant (1) présente un diamètre supérieur à celui du boulon (3) mais légèrement inférieur à celui de la tête (8) du boulon (l'écrou (4)), la tête de boulon (8)(l'écrou (4)) reposant directement contre la paroi intérieure (9) du montant (1).
