Definitions

  • This invention relates to an edge-limiting device for roadways, more particularly a guide device for the center strips between opposing ftralic lanes of roadways, and to the construction of the bottom strip for edge limitation.
  • a guide device of steel rails or other rigid material of relatively high strength and resistance to fracture is capable of deilecting the irnpinging vehicles, but 'with the unpleasant accompaniment of a non-resilient impact and the consequent severe shocks and reactions.
  • Attempts with metal grids as antidazzle screens have shown that they have insuliicient influence on dazzle, and in addition, due to deficient shock absorption on the part of the metal can lead to serious personal injuries in accidents.
  • the invention has for its object the further development of the edge-limiting device for roadways, more particularly a guide device for the center strip of roadways.
  • the edge limitation consists of Ia profile strip of resilient material which is mounted on posts, arranged at intervals apart, at a distance from the ground of substantially the wheel-hub height of passenger vehicles.
  • the profile strip may be of solid construction. lIt is, however, also possible to use plastic tubing under gas or liquid pressure. A ruptureresistant tubing may also be used, filled with a padding, for example a foam material.
  • a guide device of high elongation on rupture and shock-absorbing qualities the force of the vehicle being absorbed -fby the relatively high resiliency of the proile strip.
  • the fixing of lthe guide device strip which is advantageously adapted to be operative on both sides, is preferably .affected by mounting it on sectional irons, posts or the like arranged at intervals.
  • the profile strip is arranged in a freely suspended manner between the posts.
  • the posts themselves should be inserted iirmly in the ground, but at the same time in such a m-anner that they ⁇ are able to yield from a predetermined tensile stress upward, imposed by the profile strip.
  • the prole strip as resilient guide rail, may carry reflecting markings.
  • the edge-limiting device is combined in the manner known per se with an anti-dazzle screen.
  • plates having ia high elongation on fracture and shook-absorbing action are proposed for the anti-dazzle surfaces, preferably plastic plates, having a plain, corrugated or republicarly or irregularly opened-up surface. They should be light-transmitting but should scatter incident light in a diffused manner.
  • Such anti-dazzle surfaces at night light up the traffic 'lane by the headlights of the on-coming traic, but completely prevent dazzle or glare.
  • the antidazzle device may be arranged in laminate, which are fixed at certain angles regularly or irregularly in the direction of the Ilane above the de'liecting guide device, or it may be constructed as a continuous band.
  • the center strip between the lanes cairying oppositely-moving trafiic can be reduced in width to a substantially smaller dimension than is the case with the construction of the planted strip.
  • the center strip is consolidated throughout, such, as for example, by means of an asphalt or concrete construction, openings being provided for the guide and anti-dazzle devices.
  • the openings in the consolidated ground should be made so large that the individual post or its embedding, when stressed by ramming by motor vehicles running into it, can take up permanent deformations sufficiently to absorb the shock of the impact.
  • the joint between the post and the eener strip consolidation is advantageously closed by .a sealing compound. This has at least a lower strength than the consolidation of the center strip. yif desired, the material may also have certain resiliency.
  • the center strip may be reduced to approximately a width of 1.30 meters, whereby a substantial amount of ground is spared for the roadway itself.
  • Tlie consolidated center strip is preferably provided with a light colored surface for indicating a clear demarcation of the traffic lane.
  • FIG. 1 shows -a cross-section through the edge-limiting device for roadways according to the invention
  • FIG. 2 is a section on the line 2-2 of FIG. l.
  • FIG. 3 shows the edge-limiting device according to *he invention in perspective View.
  • the center strip 3 is situated between the usual edge-limiting strips 4 and 5, which normally have a Width of cm. and are provided with a covering of white concrete or light colored asphalt.
  • posts 6 are embedded and arranged at intervals.
  • the posts 6 having an H- section may be used, the web of the cross-section being arranged at right angles to the longitudinal direction of the traiiic lanes.
  • the posts At a predetermined low height, for example iat 'a height of 55 cm., the posts have a shoulder 6a for the suspension or attachment of profile strips 7 or plastic tubing of special strength and elongation or stretch.
  • the profile strips 7 are reinforced with metal or fibers.
  • they have a modulus of elasticity of about U-1000 kg./m.2, an elongation on rupture of about 40-100% and a tensile strength of 100G-200() l;g./cm.2.
  • the strips may be made of such a width that the opposite faces of the strips represent surfaces facing the traflc lanes, deflecting towards each lane. In the case of thick profile strips, the arrangement may be such that the strips can be pushed over the posts.
  • the shoulders 6a serve to ix the height.
  • the upper part 6b is advantageously narrower than the post ti to be set in the ground. 1n the case of a probook of H-section iron, this can be achieved by removing the flange parts from the shoulders 6a, so that only the shortened web parts 6b are left.
  • the post 6 itself is set in the consolidated ground. Between the post and the consolidated part of the ground 3 is a sealing compound S, which permits the post to yield in the event of heavy stressing.
  • Reector strips 9 may be provided on either side of the proander strip 7 facing the respective traic lane.
  • an anti-dazzle screen 10 may be provided, which preferably enables on-coming traffic to be recognized but eliminates dazzle.
  • the anti-dazzle screen should be made of material which by plastic-elastic deformation and high elongation on rupture offers an energy-destroying and at the same time shock-absorbing resistance to vehicles driving against it. It is also possible to use for this purpose a plastic which is resilient to a certain extent.
  • the posts may be set at intervals of two to three meters.
  • the consolidated center strip, with a Width of about 1.3 meters is suiiicient to satisfy the necessary safety distances.
  • an edge-limiting device for roadways more particularly a guide device for the center strip between opposing traflic lanes of roadways, posts set into the ground at spaced intervals, a reinforced prole tubular strip of shock absorbing plastic deformable material extending longitudinally of the roadway and mounted on said posts and in spaced relation to the ground line, the prole strip having registering openings in its upper and lower sides to facilitate placement of the strip on the posts through which the tops of the posts extend and shoulders on the posts and spaced from the tops thereof engaged with the upper side of the strip to hold the strip in position on the posts with the strip extending between the posts.
  • an edge-limiting device for roadways more particularly a guide device for the center strip between opposing tratiic lanes of roadways, posts set into the ground at spaced intervals, a reinforced profile tubular strip of shock absorbing plastic deformable material extending longitudinally of the roadway and mounted on said posts and in spaced relation to the ground line, the profile strip having registering openings in its upper and lower Sides to facilitate placement of the strip on the posts through which the tops of the posts extend and shoulders on the posts and spaced from the tops thereof engaged with the upper side of the strip to hold the strip in position on the posts with the strip extending between the posts, and an impact absorbing element for the post adjacent the ground line.
  • an edge-limiting device for roadways more particularly a guide device for the center strip between opposing traftic lanes of roadways, posts set into the ground at spaced intervals, a reinforced profile tubular strip of shock absorbing plastic deformable material extending longitudinally of the roadway and mounted on said posts and in spaced relation to the ground line, the profile strip having registering openings in its upper and lower sides to facilitate placement of the strip on the posts through which the tops of the posts extend and shoulders on the posts and spaced from the tops thereof engaged with the upper side of the strip to hold the strip in position on the posts with the strip extending between the posts, and a glare screen secured to the posts immediately above the profile strip.
