Definitions

  • Guardrail arrangement In the case of one arranged to the side of a lane Guardrail arrangement is known on the road surface facing side from next to the road in the ground spaced I-shaped posts both in the mid-range and at to provide the upper end in cross-section C-shaped profile strands ("Guidelines for the implementation of guardrails", Swiss Federal Office for Road Construction, edition 1982, Chapter 4.5, page 70).
  • Set the profile strands composed of individual profile shots that have no head start put together and by internal tabs are screwed together.
  • the open pages the profile strands face the posts. Your to the Short flanges lying through mullions are through tabs and Screw bolts clamped to the posts.
  • Profile strands are screwed onto tubular buffers.
  • the longitudinal axes of the buffers run vertically. Their height is smaller than the height of the profile strand.
  • the buffers are arranged in transverse planes, in which the webs of the posts extend, as well in transverse planes between the posts.
  • the buffer On the carriageway side, the buffer is a W-shaped cross section Guardrail strand screwed on.
  • the guardrail line like the profile strands, it consists of individual guardrail sections together, which are screwed together.
  • To brace the guardrail line are short rectangular profile pieces between the buffers and the Guardrail line integrated. These profile pieces will when screwing the guardrail string to the Buffering specified. Your horizontally aligned Legs reach into longitudinal recesses facing away from the road of the guardrail line.
  • the invention is based on the prior art Task based on the known guardrail arrangement further develop that they are double-sided Construction for narrow median strips in particular between two lanes with oncoming traffic under the conditions of the trial TB 61 can be used.
  • the trial TB 61 means that a vehicle with a Total weight of 16,000 kg under an impact angle of 20 ° at a speed of 80 km / h against the Guard rail arrangement is hurled.
  • the Guardrail arrangement an energy of approximately 420,000 N to record. This value is about twice as high that of trial TB 51.
  • the invention now achieves this in that the upper ends of the posts on both sides C-shaped profile strands provided this with the post at least indirectly via predetermined breaking points and across transverse Coupling links are interconnected.
  • Such Design leads to an impact and itself then the two posts bending away from the roadway upper profile strands can come loose from the posts, because they're part of a longitudinally stretched one Harnesses strive to maintain their stretched position.
  • the cross connection of the profile strands through the coupling elements helps that the not the profile strand facing away from the road with the posts is bent sideways and down and then no longer contribute to the absorption of the impact energy can.
  • the invention thus creates a compact, stable fall arrester in the area of the upper ends of the posts, which can still easily detach from the posts and as Part of the guardrail arrangement is the inclusion of a Energy of approximately 420,000 N guaranteed.
  • the invention makes it particularly advantageous Way, an effective guard rail arrangement even on such to arrange narrow median strips, the two at height level separate different lanes. It is only necessary to do the roughly middle height range of profile strands attached to the posts and those with these over the tubular buffers connected guardrail lines in height accordingly to be staggered.
  • Guard rail arrangement is made according to the characteristics of claim 2 seen in that at the upper ends the post-provided C-shaped profile strands of U-shaped brackets in the area of the posts are over and / or under attacked. This makes the compactness of the fall arrester even further increased. Furthermore can the two profile strands after a separation from the posts, bulging the webs of the brackets ultimately support each other, so that this Rigidity of the two profile strands and the brackets existing containment belt further increased becomes. The brackets are connected to the posts Not.
  • Another embodiment of the invention consists of the features of claim 3 in that the coupling links as spacers in the C-shaped profile strands are trained. The connection is not made here the profile strands with the posts. That's what they're for Spacers connected to the posts.
  • the spacers according to claim 4 are useful with screwed U-profiles and on the front the profiles attached, with the C-shaped profile strands connected tabs formed.
  • the C-shaped profile strands therefore have no direct connection of their own with the posts. Rather, this is done exclusively by the spacers.
  • the coupling links are screwed to the profile strands.
  • the fittings then lie when using U-shaped Brackets both in the area of the horizontal webs Profile strands as well as the outside vertical Leg. If spacers are used, so are this over the tabs with the outside legs screwed.
  • the posts preferably have a C or sigma-shaped cross-section, being accordingly the length of the respective local requirements are.
  • the open areas of the posts show in the longitudinal direction of the median.
  • the definition of the middle height of the posts provided C-shaped profile strands on the posts preferably according to the features of claim 8.
  • special clamp hooks are used.
  • the Clamping hooks can e.g. an integrated threaded sleeve with have an internal thread for a screw bolt.
  • the bolt is made from the inside of a profile strand rotated into the threaded sleeve and pulls over the Hook the profile strand to the post.
  • the Hook have a wedge-shaped hook mouth with which he engages over a flange of the post. It is convenient two clamping hooks one above the other. The heads of the two Screw bolts are then supported on a tab, which on the inside of the flanges of the profile strand comes to lie.
  • the clamp hooks can also have through holes having sleeves connected in one piece be inserted through the bolts that either in threaded holes, which in the to the Flanges of the profile strands coming into contact with the system are provided, or it is on the thread of the Bolt nuts turned, which are then attached to the tabs issue.
  • the clamping hooks are preferably made of a corrosion-resistant one Material such as brass.

  • FIGS. 1 to 4 they are the same middle height range of the posts 4 on both sides in vertical cross section C-shaped profile strands 7 on the Post 4 attached.
  • the profile strands 7 are fixed with the aid of tabs 9, clamping hook 10, bolts 11 and plastic plates 12.
  • the clamping hook 10 are made up of a Threaded sleeve 13 and from one with the threaded sleeve 13th integrally connected hook 14 with a rectangular Hook jaw 47 together.
  • the clamping hook 10 consist of Brass.
  • the clamping hooks 10a instead of the rectangular hook jaw shown in FIG. 6 47 for a flange 15 of a post 4 also wedge-shaped Have hook jaws 47a.
  • the tabs 9a can also have through holes have, so that then on the free ends 63rd the bolt 62 nuts are inserted.
  • the profile strands 7 consist of individual profile sections 19, which are screwed together at the end (FIG 1).
