Definitions
- the invention relates to a restraint system comprising posts fixed to the ground and to the posts, incorporating spacers, spars according to the preamble of claim 1.
- 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 plates, which are fixed on the structures. Horizontal security elements as a handrail are connected to the posts. The spars are connected via spacers or damping elements in each case with the posts. Between the posts are also pressryogllungen attached. Even if the distance or Dämpfungsele ⁇ elements can be connected in a variety of ways with the posts or the spars, an advantageous connection is seen in a screwed 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' and are similar to two extended by an arc 'S', whose ends are connected by two webs. These three semicircles of the extended by an arc 'S' are pushed together on impact by a vehicle and thus dampen the impact energy.
- the upper damping elements or profiles can also describe the upper damping elements or profiles as one of two straight and opposite fastening webs, one of which is attached to the post and the other to the inner legs of the spars. Between the two fastening webs which are attached to the post and to the inner legs of the spars are located at the ends of the fastening webs each two corrugated Dämpfstege which consist of at least two outgoing sheets and at least one inward-going arc.
- the inner and outer bows can be adapted to the requirements in terms of size and position. In their preferred embodiment, these damper webs each have two outgoing arches and an inward going arc.
- the transition between the fastening webs and the damper webs is through the first arc evenly between the two mounting webs of the damping element and the vertical post or the inner leg of the spars can for Increasing the load carrying capacity still additional each one feed element to be mounted.
- a feed element is mounted only between the damping element and the inner leg of the spars.
- the chuck element has at least two holes and is clamped by the guard rail screws between the damping element and the inner leg of the guard rail spars.
- the lining element may be made of a metallic material z. B. steel but also be made of plastic or rubber.
- This basic structure is designed so that it can be easily modified according to the locally required retention level.
- 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 fulfill 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.
- An advantageous embodiment of the restraint system according to the invention is seen in that below the upper spar a second spar is arranged. This embodiment is preferably used when an underrun protection is required in addition.
- the upper spars can be usefully mounted at a mean height Ho of 500 mm to 800 mm to the driveway, preferably at a mean height Ho of 600 mm
- the lower spars can be usefully attached at a mean height Hu of 130 mm to 370 mm to the driveway, preferably they are mounted in a mean height Hu of 200 mm to 300 mm.
- a handrail which is at the upper ends of the posts may be provided on the restraint system.
- This handrail in another embodiment, may have 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 or of a material with steel-like properties.
- the shape of the special hollow profile can be z. B. be an inside open 8 or 6-or 8-square or and or these shapes similar profiles.
- FIG. 1 front view of a length portion of the restraint system
- Figure 3 top view of a length portion of the restraint system
- the restraint system shown in FIG. 1 consists of foot plates (5) anchored to the ground at the edge of a carriageway or corresponding structures.
- the foot plates (5) are z. B. by dowels (8) attached to the roadway or corresponding structures.
- the vertical posts (4) are mounted. To increase the retention capacity are not at the
- the required tolerance compensation (7) to the structure is made using a mortar layer, rubber plates or other plastic plates. Preferably by EPDM plates.
- the spars (2a, 2b) are formed from weft-wise juxtaposed profiles (shots), which have a U-shaped, W-shaped or similar configuration in cross-section.
- the spacer or damping elements (3a, 3b) are mounted horizontally in their direction of action (see Fig. 1) to the post.
- Each post (4) consists of an I, C or similar profile (eg closed).
- the central web of the profile extends transversely to the bars (2a, 2b).
- the spacer or damping elements are screwed or attached with other fasteners.
- Figure 2 shows the restraint system in a horizontal view from the roadway seen in the direction of impact and Figure 3 shows the restraint system from above.
- the spars (2a, 2b) are, as previously described, set in two different heights Ho, Hu.
- the upper spar (2b) is closer to the track than the lower spar (2a).
- the spars (2a, 2b) can also be mounted at the same distance from the roadway and the lower spar (2a) can be closer to the track than the upper spar (2b).
- the ratio of the distance Ao of the front of the upper stringer strand (2b) from the post (4) to Distance Au of the front of the lower beam strand 2a to the post 4 in a range between 3.0: 1 to 1.0: 1, preferably 1.94: 1.
- the upper and lower damping elements (3a, 3b) used on the upper and lower spars (2a, 2b) may be the same or different in shape, size and rigidity.
- a lining element (11) is mounted between the damping element (3a) and the inner leg of the spars (2b).
- the chuck element (11) has at least two holes and is clamped by the guard rail screws between the damping element (3a) and the inner leg of the spars (2b).
- the lining element (11) can be made of a metallic material such. B. steel but also be made of plastic or rubber.
- the upper spar (2b) is first contacted in each case.
- the first damping elements (3b) of the upper 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 spar is thereby displaced so far in the direction of the posts (4) until the repellent away from the path back / -fikiee rests on the post (4) 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 protective function is still maintained despite a strong Auffahrbelastung.
- Fig. 4 shows some forms for the damping element: a) a steel profile in the form of an inside open '8' and is similar to two extended by an arc ' S', whose ends are connected by two webs. b) profile consisting of two straight and opposite fastening webs (14) describe one of which is attached to the post and the other to the inner legs of the spars. Between the two fastening webs (14) which are attached to the post and the inner leg of the spars are located at the ends of the fastening webs (14) in each case two corrugated Dämpfstege consisting of at least two outgoing sheets (12) and at least one going inward Bow (13) exist.
- the inner and outer bows can be adapted to the requirements in terms of size and position.
