Definitions

  • the invention relates to a Leitschwellenan extract with the features of Preamble of claim 1.
  • the invention is based on the object, in a closed Guidance threshold arrangement between two lanes at least to provide a median barrier, which if needed in the shortest possible time can be opened to fürzuschleusen vehicles and which in the opened state requires no additional lateral space.
  • the essence of the invention is that the border sections of the median barrier an open at the bottom, on the cross section of the Leitschwellenschiff have tuned U-shaped cross section, so that the Barriers across the threshold crossings, linearly along the Leitschwellenschiff are displaceable.
  • the linear displacement sets a particular U-shaped cross-sectional configuration of the barrier shots advance so that the interior of the gate openings when open Median barrier as completely as possible from the Leitschwellenschdorfn is completed.
  • the carrying roller rolls when moving the gate shots on the upper Surface of the Leitwellenschadore off, so that the border shots already with low muscle power can be moved. With several together It is sufficient, if within each Schrankenschusses a single support roller is arranged. Of course can also provide several carrying roles within each bounds shot be.
  • the carrying rollers are made of a weather-resistant material.
  • the legs of the U-shaped profile are profiled wavy (claim 3).
  • the wavy Profiling gives the legs a sufficient transverse rigidity and ensures the dimensional stability of the Leitschwellenan extract invention in the area of the median barrier.
  • the Profiling in an impact on the required deformation resistance.
  • the Individual barriers shoots can easily be done in a continuous process a normal guardrail made of two identically profiled half shells become.
  • the half-shells can be folded in the upper edge region, wherein the bends to one, the legs interconnecting web be welded, so that the U-shaped cross-section results.
  • the length the leg, the width of the bridge, as well as the U-shaped configuration as a whole depends on the cross section of the threshold thresholds and can basically be adapted to these within wide limits.
  • the subject of claim 4 is that every shot on the border Support post is detachably associated.
  • the support post has at its foot end a support roller on (claim 5).
  • the support posts serve as support the Leitschwellenan für extract on the ground.
  • over the Support post dependent on the weight of the central barrier Resistance applied to the median strip. Up to a certain Length of the median barrier is the resistance is large enough to prevent the center strip barrier in a collision on the Dimensions strongly shifted laterally and possibly in the parallel lane is thickened.
  • the at least one support roller at the foot of the support posts has the same orientation as the carrying roller between the wavy profiled thighs of the Barriers. The supporting role also contributes in that the median barrier is opened by muscle power alone can.
  • the lower heights of the legs over cross-bolts and spacers with the support post are lockable.
  • the transverse rigidity of the barrier shots is increased by this transverse lock in the lower area, as in Area of the transverse bolt results in a closed box profile.
  • the cross bolts also serve to fix the support posts within the gate shots.
  • spacers between the support posts and the Inner sides of the legs are arranged so that the cross section of the support posts not attuned to the profile of the individual border shootings needs to be. It can have slim support posts with a flat outer surface used from the top, i. through the jetty in the Interior of the individual barriers shots are introduced and over the interposed custom-fit spacers laterally oriented become.
  • a support post may preferably a square tube with rounded Corners are used.
  • This square tube with a support roller on lower end may be provided with a handle at its upper end, which is welded to a round blank.
  • the round blank ensures that the support post not through the insertion opening in the top of the Barrage shot slips.
  • the spacers themselves from the cross bolt be penetrated to an exact positional orientation of the support tube and at the same time to ensure the spacers.
  • the spacers in an advantageous embodiment be configured wedge-shaped.
  • the support rollers are height adjustable relative to the support posts. Especially the support rollers are integrated into the support posts and in the walls of the Support posts stored. The support rollers are then not over the outer circumference the support post in front. About the height adjustment, it is possible to lower the bounds of bounds, so that they serve as support brackets trained spacers can come into contact with the ground and Thus, the desired resistance can be applied.
  • the center strip barrier must be opened, are the support rollers to bring it back into a position where the spacers are off the ground again take off, so that the resistance is lifted. That is, the Support rollers must be shifted downwards. In the raised position the center strip barrier can be opened easily.
  • the Spacers are depending on the configuration at its upper end only by the cross bolt between the support post and the inside of the legs clamped fixed. Will the clamping force, for example, in an impact overcome, can be ensured by the additional locking pin be that the spacers maintain their intended position.
  • the Locking pins are preferably at a greater distance from the transverse bolt arranged to give as uniform a force as possible in the Support post or in the spacers to allow.
  • the median barrier of the invention Leitschwellenan extract should basically be quick to open and with little effort, taking At the same time it must be ensured that a secure connection to the borderline thresholds. Therefore, according to Claim 11 intends that with the median barrier connected Leitschwellenschadore bottom side anchored and preferably are anchored. Anchoring ensures that in one Median barrier introduced impact force on the adjacent Leitschwellenschadore is initiated in the ground. The corresponding Leitschwellenschadore serve as a kind of barrier post the Central reservation barrier.
  • the anchoring can be done by one or more Ground nails are made when the threshold bumps on the ground are set up. With a paved floor, such as a concrete floor, can one or more fastening bolts with dowels for fixing the Leitschwellenschusses be used.
  • successive barriers shots abut each other frontally and are interconnected by inner tabs (claim 12).
  • the Tabs can be both in the area of the bridge and on the side Thighs of the Barriers may be provided to a sufficient To ensure rigidity of the median barrier.
  • the individual shots of Middle barrier barrier pre-assembled in the factory and ready at the construction site be put.
  • the individual Barriers to be patched together on site.
  • the two lengths can by a vertical latch comprehensive coupling agent releasably connected to each other.
  • the coupling agents include one frontally of a barrier shot in the longitudinal direction projecting pin portion and a receiving portion corresponding to the pin portion in the front of the adjacent border shot (claim 14). The pin portion and the receiving portion are through Insertion of the vertical bar coupled together.
  • the pin sections therefore have a certain minimum length, so that a sufficient overlap of the Spigot portion with the receiving portion for mutual stiffening is guaranteed.
  • the recording section may include the shot Pin portion with the receiving portion by inserting the Vertical bolts are locked. This kind of connection of the two Length sections allows a particularly rapid opening of the Central reservation barrier.
  • the Leitschwellenschüsse the Leitschwellenan extract according to claim 15 are made of trapezoidal casings, upper rectangular spars and the Housing formed with the spars connecting posts. These also called “Vario Guard "known type of steel is a preferred application for the Leitschwellenan extract invention. Basically, the Leitschwellenschiff also from non-metallic, especially mineral Materials, such as Concrete exist. It is favorable here, if the Leitschwellenschüsse a trapezoidal in cross-section base and a have upwardly tapered bridge. Such concrete sleepers are Also known as "New Jersey” type (claim 16).
  • FIG. 1 shows a threshold barrier arrangement 1 which is not closer between two shown lanes on a central strip 2 is arranged.
  • the Threshold arrangement 1 is made of several releasably juxtaposed Leitschwellenschadoren 3, 4 formed, wherein between the Leitschwellenschadoren 3, 4 a median barrier 5 is arranged.
