Definitions

  • the present invention relates to a guard rail arrangement for a vehicle restraint system for securing roadways with a plurality of profile posts that are anchored or anchored in a ground, at least one along a longitudinal axis extending guard rail and at least one spacer element arrangement, by means of the guard rail each with one of the profile posts is coupled or coupled, wherein the roadway at least one spacer element arrangement between at least one of the profile posts and the at least one protective barrier strand is arranged, wherein the at least one spacer element arrangement is attached or attachable via a base portion with at least one cap screw on the associated profile post and each with at least one contact portion for Connection with the at least one protective barrier string are formed.
  • a guard rail arrangement of the type described in which it is provided that the base portion or the profile post is formed with an insertion recess and an opening into this slot, wherein the insertion recess for receiving the screw head or a retaining nut formed on the cap screw and wherein the slot is matched to the diameter of the screw shaft of the cap screw.
  • the protective barrier strand is first preassembled with the spacer element arrangement. As a result, then this preassembled module is raised, with individual screw threads can already be introduced by already attached to the profile post head screws in the insertion of the protective barrier strand.
  • the subassembly comprising the guard rail is displaced relative to the tread post and cap screws attached thereto such that the bolt shank extends through the slot in the base section.
  • the slot is designed so that the screw head or a retaining nut on the cap screw can not slide through it.
  • the protective barrier is therefore already held loosely on the profile post without additional assembly personnel - as required in the prior art - must hold the guard rail in position relative to the profile post. This results in a considerably simplified installation.
  • the slot extends with its longitudinal direction in the vertical direction.
  • the guard rail automatically, ie due to gravity, moved to a "locking position" in which the screw head or the retaining nut slides after threading into the insertion recess along the slot and thus engages behind this.
  • the assembly comprising the protective barrier strand is already held loosely against the profile post via the unscrewed cap screws or retaining nuts.
  • the insertion recess is arranged at one end of the slot.
  • a preferred embodiment variant of the invention provides that the at least one spacer element arrangement is delimited lengthwise in the direction of the longitudinal axis to a region at or near the respective profile post and in the direction orthogonal to the longitudinal axis in a central region between the base section and Contact section is angled several times. This means that the spacer element arrangement is limited in each case to profiled post near areas and does not extend over the entire length of the protective barrier strand.
  • the spacer element arrangement is formed with at least two connecting legs between the base section and contact section, wherein each connecting leg has at least two kinks which lie substantially within a range of the middle third of the effective length of the respective connecting leg from base section to contact section. From such a configuration of the spacer element arrangement results in a directed deformation behavior, so that an undesirable underrun or Hinwegsg suits a vehicle can be prevented in an impact on the protective barrier arrangement according to the invention.
  • the kinks in the connecting legs in each case form vertices of mutually opening, preferably blunt, angles.
  • the connecting leg at least partially parallel.
  • a simple production of the spacer element arrangement results, for example, in that the spacer element arrangement is formed in one piece, wherein the two connecting legs are connected to one another via a common base section.
  • the spacer element arrangement is designed in several parts.
  • the connecting legs are designed to be telescopic in the direction orthogonal to the longitudinal axis. As a result, the distance of the protective barrier from the profile posts can be changed.
  • the spacer element arrangement is formed with at least one spacer element which is formed in cross-section with a closed polygonal profile with predetermined kinks, wherein a first polygon side attached to the associated profile post or attachable is and wherein a further polygon side is formed for connection to the at least one protective barrier strand.
  • the polygonal profile has the shape of a, preferably regular, hexagon.
  • adjacent spacer elements connected to each other via polygon sides, preferably welded together.
  • each of the spacer elements has a polygonal profile axis, wherein the polygonal profile axes of at least two of the spacer elements between one of the profile posts and the protective barrier strand run substantially parallel to one another.
  • each of the spacer elements has a polygonal profile axis, wherein the polygonal profile axes of at least two of the spacer elements between one of the profile posts and the protective barrier strand are essentially skewed, in particular orthogonal, to one another. As a result, the direction of the deformation can be further stabilized.
  • the invention further relates to a spacer element arrangement for a vehicle restraint system with a guard rail arrangement of the type described above, wherein the spacer element arrangement is designed such that it deforms impact-dependent, wherein the at least one spacer element arrangement is attached or attachable via a base portion with at least one cap screw on the associated profile post and formed in each case with at least one contact portion for connection to the at least one protective barrier strand, wherein the base portion or the profile post is formed with an insertion recess and an opening into this elongated hole, wherein the insertion recess for receiving the screw head or a retaining nut is formed on the cap screw and wherein the slot is matched to the diameter of the screw shaft of the head screw.
  • the invention relates to a vehicle restraint system with a guard rail assembly and a spacer assembly of the type described above.
  • a guard rail assembly according to the invention is generally designated 10. This includes a plurality of profile posts 12, only one of which is shown.
  • the profile post 12 extends substantially orthogonal to a substrate, not shown, and is firmly anchored in this.
  • the protective barrier arrangement 10 according to the invention comprises a protective barrier strand 14 which extends along a longitudinal axis A.
  • the guard rail 14 is shot by piece composed of individual elements, as is known. Between the profile post 12 and the protective barrier 14, a spacer element assembly 16 is provided on each post.
  • the spacer element arrangement 16 connects the protective barrier strand 14 with the profile post 12.
  • the spacer element arrangement 16 comprises a multiply angled sheet metal part 18 with a base section 20. Starting from the base section 20, two connecting legs 22 and 24 initially extend obliquely upwards. The two connecting legs 22 and 24 run substantially parallel to a central region in which they have a vertex at reference numerals 26 and 28, respectively. At these apexes 26 and 28, each connecting leg 22, 24 is angled downwards at an obtuse angle and extends over a short sloping portion 30, 32 to a second vertex 34, 36.
  • a spacer strut 50 which connects the two connecting legs 22 and 24 with one another and stabilizes their position, is arranged near the central region having the apexes 26 and 34 as well as 28 and 36.
  • the spacer bar 50 may be connected to the connecting legs 22 and 24 via screws or rivets indicated only by axes 52, 54 or else by welding.
  • the base section 20 and the spacer strut 50 and the sections of the connecting legs 22 and 24 extending between these two form a closed polygonal profile in the spacer element arrangement, which gives the spacer element arrangement high stability in the event of a force corresponding to arrow F.
  • the angular courses at the apexes 26 and 34 as well as 24 and 36 and the oblique course of the profile post near connecting leg sections ensure directional deformation behavior of the spacer element arrangement 16, in particular such that with acting forces F in the event of a collision of a vehicle, the protective rail section 14 adjoins the profile post 12 can create without breaking up or down undefined ".
  • head screws 56 and 58 are provided, which can be mounted on the profile post 12 preassembled. This is done, for example, such that the cap screw 58 is inserted into a bore in the profile post 12 and is countered with a nut 60 (or 62) so that it is firmly connected to the profile post 12.
  • each elongated holes 64 are provided, as shown in particular in Figure 2.
  • the elongated holes 64 have at their lower end an insertion recess 66 whose diameter d is matched to the maximum outer diameter of retaining nuts 68, 70. This means that the diameter d of the insertion recesses 66 is dimensioned such that the retaining nuts 68 and 70 can be inserted therethrough.
  • the width w of the slots 64 is adapted to the shaft of the cap screws 56 and 58 and considerably smaller than the diameter d of the Ein slaughterhouse 66th
  • the procedure is as follows, with reference to FIG. First, the profile post 12, as already described above, equipped with the cap screws 56 and 58, wherein then the lock nuts 60 and 62 are screwed. Thereafter, metal discs 72, 74 are pushed onto the shaft of the cap screws 56 and 58. Finally, the retaining nuts 68 and 70 are loosely screwed onto the free end of the shank of the cap screws 56 and 58, leaving a clear gap between the metal discs 72 and 74 and the respective retaining nuts 68 and 70.
  • the retaining nut 68 or 70 engages behind the base section 20.
  • this assembly can no longer fall off the profile posts 12 , Rather, it is held by the retaining nuts 68 and 70 - albeit loose - on the profile post.
  • the retaining nuts 68 and 70 can be sufficiently tightened by the assembly staff to prevent inadvertent release, even at high forces F in the event of an impact.
  • the guard rail assembly 110 differs significantly in their structural design of the guard rail assembly 10 according to Figures 1 to 3.
  • the spacer element arrangement of two mutually rotated by 90 ° hexagonal hollow profile elements 180 and 182 is formed, which are welded together at their sides facing each other Polygonalt.
  • the cap screws 156 and 158 were assembled in a manner corresponding to the first embodiment of the hexagonal hollow profile elements 180, that is inserted into corresponding holes, with lock nuts festgekontert provided with metal discs and with Retaining nuts 68 and 70 were fitted at their free ends.
  • the profile post 112 is provided with a combination of oblong holes and insertion recesses 164 and 166. This is indicated only schematically in Fig.4 by axes. It should be noted that the slot 164 is disposed below each of the insertion recess 166.
  • the assembly takes place in the same way. This means that first the cap screws 156 and 158 are pushed through the insertion recesses 166, as indicated by arrow P 1 . Then, according to arrow P 2, the assembly of guard rail 114 and spacer element assembly 116 is lowered, so that the shaft of the cap screws 156 and 158 slides into the slots 164 and the retaining nuts these slots 164 engage behind. As a result, then the retaining nuts on the cap screws 156 and 158 are tightened.
