Definitions

  • the present invention relates to an arrangement according to the preamble of claim 1 for securing, to a post adjacent a carriageway, a crash barrier comprising an open profile in its longitudinal direction, an anchorage element with a portion designed to be accommodated interiorly in the profile, said portion having a transverse dimension which, at least in one direction, is larger than the longitudinal opening, a bracket which extends transversely over the opening of the profile, and a clamping member for drawing the anchorage element towards the post.
  • the present invention also relates to a method according to the preamble of claim 9 of securing to a post, a crash barrier with a profile provided with a longitudinal opening, the method comprising the step that an anchorage element is moved in interiorly into the profile, an U-shaped bracket is placed transversely over the longitudinal opening of the profile so that edge flanges, which are disposed along the opening of the profile are accommodated between the shanks of the bracket.
  • crash barriers A number of various types of so-called crash barriers are previously known in the art.
  • a very commonly occurring type of crash barrier is such which consists of one or more metal profiles substantially parallel with the ground.
  • the profile or profiles have a substantially W-shaped cross section, with two longitudinal ridges or bights. Between the ridges, there is a depression-shaped portion which is often utilised to secure the metal profiles to those posts which support the crash barrier.
  • parts of the anchorage elements will be visible on that side of the barrier facing towards the carriageway. This is not only an aesthetic drawback, but also increases the risk of serious damage to vehicles and injury to their occupants, since there is an imminent risk that a colliding vehicle fastens in the anchorage elements. Instead, a correctly designed crash barrier should act so as to return the vehicle back into the carriageway after a possible collision with the crash barrier.
  • NO 127 931 discloses a crash barrier which lacks a number of the above-mentioned drawbacks.
  • the crash barrier displays a surface without projections in which a colliding vehicle may fasten.
  • the profile is supported by posts, preferably of wood, whose cross section corresponds with the cross section of the profile.
  • posts preferably of wood, whose cross section corresponds with the cross section of the profile.
  • each one of the supporting wooden posts must be given the cross section of the metal profile, which is both time- and labour-consuming.
  • Another drawback is that the posts and metal profiles are not otherwise interconnected to one another, which, at least with the passage of time, would entail that the crash barrier becomes unsteady.
  • WO 98/42918 discloses a crash barrier according to the preamble of claim 1 including posts and at least one substantially horizontal profile with a longitudinal opening. The profile is secured to the posts respectively by means of an attachment part and two washers which are placed on either side of the opening and drawn towards each other on tightening of the attachment part. The edges of the opening are simply placed between the washers, and may be loosened therefrom if the attachment part is not tightened hard enough.
  • the objects according to the present invention will be attained if this is characterized in that the anchorage element exercises an interior wedging effect against the profile so that its edge flanges are urged outwards towards the inside of the bracket.
  • reference numeral 1 refers to a crash barrier which is disposed along a carriageway or roadway, in order to catch a motor vehicle which, for one reason or another, has gone off course.
  • Reference numeral 2 relates to a post secured in the ground which, by the intermediary of a laterally horizontally projecting bracket 3, supports a metal profile 4 which constitutes the crash barrier proper and which extends approximately horizontally along the carriageway at a level which is flush with the hubcap region of an average motor vehicle.
  • the profile 4 has an approximately circular main portion 12 which is turned to face towards the carriageway.
  • the main portion 12 On its side facing away from the carriageway, the main portion 12 has a longitudinal opening 11 with edges 10.
  • the profile 4 has edge flanges 13 which are approximately horizontal and parallel with one another and which are disposed one along each edge 10 of the opening 11. The edge flanges 13 are thus located on the side of the barrier turned to face away from the carriageway.
  • the portion 14 of the anchorage element 5 has two plate-shaped side pieces 8 which are disposed in spaced apart relationship from one another and are approximately mutually parallel, and are provided with edge portions 15 for abutment interiorly against the inner surface of the profile 4 on either side of the opening 11.
  • the edge portions 15 are shaped in order, when the anchorage element 5 is subjected to a drawing force out of the main portion 12 of the profile and out between the edge flanges 13, to realise a wedging effect which strives to broaden or flare the opening 11 and move the edge flanges 13 away from one another.
  • the edge portions 15 may be approximately complementary to the inner surface of the profile 4 in the contact region with the anchorage element 5.
  • a bracket 3 On assembly of the crash barrier 1, a bracket 3 is caused to straddle the edges 10 and the longitudinal opening 11 transversely of the longitudinal direction of the opening 11.
  • the anchorage element 5 which has a cross-sectional dimension which is less than the width of the longitudinal opening 11, is moved into the longitudinal opening and is thereafter twisted through approximately 1/4 of a revolution. It is then impossible to draw the anchorage element straight out through the longitudinal opening 11, since parts 15 of the anchorage element 5 abut against the inside of the profile 4. Thereafter, the profile 4 and the anchorage element 5 are clamped against the bracket 3 and the post 2 with the aid of a clamping member 6, for example in the form of a bolt or screw provided with a nut.
  • the anchorage element 5 When the clamping member 6 is tightened, the anchorage element 5 is drawn steadily closer to the post 2 and the bracket 3.
  • the anchorage element 5 is provided with two side pieces 8 whose profile partly corresponds with the inner cross section of the profile 4.
  • the anchorage element 5 thereby exercises an interior wedging effect on the profile 4 so that its edges 10 are forced apart at the same time as being urged against the insides of the bracket 3.
  • Figs. 6 and 7 show an alternative embodiment of the anchorage element 5.
  • the main principles of how the anchorage element, by wedging effect, clamps the profile 4 against the bracket 3 are the same as those described in the foregoing, but the anchorage element has a partly different composition and method of use.
  • the anchorage element 5 is provided with two holes 7 between the side pieces 8.
  • the anchorage element 5 in the alternative embodiment does not have a transverse dimension which is less than the width of the longitudinal opening 11 in the profile 4.
  • the anchorage element 5 is inserted from the short side of the profile and is thereafter shifted a longer distance to the bracket 3 for securement.
  • the securement will be more stable, even though the assembly operation will be slightly more complicated.
  • Figs. 4 and 5 relating to the preferred embodiment, it is clearly visible that the bracket 3 has been secured to the post 2 with one clamping member 6 and that the profile 4 has been secured to the bracket 3 by means of an additional clamping member 6.
  • the bracket 3 is first mounted on the post 2, whereafter the clamping member 6 on which the anchorage element 5 is mounted is slid into the slot 9 in the bracket 3.
  • a construction entailing that the bracket 3, the anchorage element 5 and the profile 4 are secured to the post 2 using one and the same clamping member 6 should be appropriate.
  • the assembly operation when the clamping member 6 is to be inserted into a hole 16 in the post 2 may be slightly more complicated, but in return a considerably fewer number of clamping members 6 taken as a whole needs to be tightened.
