Definitions

  • the invention relates to a restraint system comprising ground-mounted posts and to the posts, incorporating spacer elements, guard rail posts according to the preamble of claim 1, as disclosed in the document DE 199 07 954 in which a protective device is disclosed.
  • the invention is therefore, starting from the prior art, the object of the invention to provide a lightweight and cost-effective restraint system that meets the high security requirements.
  • the solution to this problem consists in the invention of a restraint system according to claim 1.
  • This restraint system consists of vertical posts with foot plate, which are fixed on the structures. Horizontal security elements as a handrail are connected to the posts.
  • the guard rail spars are connected via spacer or damping elements in each case with the posts. Between the posts are also pressryogllungen attached. Even if the spacer or damping elements can be connected in a variety of ways with the posts or the guard rail spars, an advantageous connection is seen in a threaded connection.
  • the fastening by means of screws is simple, reliable and easy to assemble and repair.
  • the upper damping elements consist of a steel profile in the form of an inside open '8'. These are fastened to the posts once and to the inner thighs of the guardrail bars. This basic structure is designed so that it can be easily modified according to the locally required retention level. It is particularly advantageous, however, that this restraint system can be used both on a median strip between two driveways as well as the edge of a guideway.
  • the construction of the restraint system is simple and economical.
  • the used damping elements feel their function reliably.
  • the steel profiles of the damping elements can be efficiently produced in large quantities at low cost. In practical experiments, a very good start-up behavior was achieved.
  • the underrun protection of the restraint system i. at the lower Leitplankenholm spacer elements, which can also a damping elements, provided, which are fixed once to the posts and the other to the inner legs of the guard rail Holmes.
  • the upper guide rail spars can be usefully attached at a mean height Ho of 500 mm to 800 mm to the driveway, preferably they are mounted at a mean height Ho of 600 mm to 700 mm.
  • the lower guard rail spars can be usefully attached in a mean height Hu of 130 mm to 370 mm to the track, preferably they are mounted in a mean height Hu from 200 mm to 300 mm.
  • a handrail provided with the upper ends of the posts may be provided on the restraint system according to claim 6.
  • This handrail in another embodiment, may include an internal steel cable that is fixed to each post to provide a better interaction of the posts in the event of an impact.
  • the damping elements may consist inter alia of a special hollow profile made of steel or similar material.
  • the shape of the special hollow profile may be e.g. which are profiles which are open on the inside or 8 or 6 or 8 and / or of these shapes.
  • restraint system (1) consists of edge of a roadway or corresponding structures in the ground anchored foot plates (10).
  • the foot plates (10) are fastened by dowels (8) on the roadway or corresponding structures.
  • the vertical posts (4) are mounted on the foot plates.
  • stiffening plates (9) are mounted between the foot plate (10) and the posts (4) on the side not facing the roadway.
  • the upper guard rail spar (2b) closer to the roadway than the upper guard rail spar (2a).
  • the guard rail spars (2 a, 2 b) are formed from guard rails (shots) which are placed against each other in a weft-like manner, which have a U, W or similar configuration in cross section.
  • the distance or damping elements (3a, 3b) are horizontal in their effective direction (see Fig. 1 ) attached to the post.
  • Each post (4) consists of an I, C or similar profile (eg closed).
  • the middle web of the profile extends transversely to the guard rail spars (2a, 2b).
  • the spacer or damping elements are screwed or attached with other fasteners.
  • FIG. 2 shows the restraint system in vertical view and FIG. 3 shows the restraint system seen from the roadway in the impact direction.
  • the guide rail spars (2a, 2b) are, as previously described, set at two different heights Ho, Hu.
  • the upper guard rail spar (2b) is closer to the track than the lower guard rail spar (2a).
  • the guide rail spars (2a, 2b) can also be mounted at the same distance from the roadway and the lower guard rail spar (2a) can be closer to the track than the upper guard rail spar (2b).
  • the ratio of the distance Ao of the front of the upper guardrail (2b) from the post (4) to the distance Au of the front of the lower guardrail 2a to the post 4 is in a range between 3.0: 1 to 2.0: 1, preferably 2 , 57: first
  • the upper and lower damping elements (3a, 3b) used on the upper and lower guard rail spars (2a, 2b) may be the same or different in shape, size and rigidity.
  • the upper guard rail spar (2b) is first contacted in each case.
  • the first damping elements (3b) of the upper guard rail spar (2b) are deformed, as a result of which impact energy is dissipated.
  • the posts (4) remain largely unencumbered in this deformation phase.
  • the upper guard rail spar is displaced so far in the direction of the posts (4) until the repellent away from the track back / surface on the post (4) is applied or the damping element is completely compressed. In this way, the post (4) until then largely without large force influence. Only in a second deformation phase, the force on the post (4) goes over. However, the guardrail function is still maintained despite a strong Auffahrbelastung.
  • the damping elements are compressed.
