Definitions

  • the invention is directed to a guide threshold line for motor vehicles according to the features in the preamble of claim 1.
  • Such a guide threshold strand is part of the prior art through US Pat. No. 3,658,300.
  • the approach plates of the guide sleepers which are not coupled to one another in the longitudinal direction are curved according to a parabolic function, the edge regions adjacent to the lower longitudinal edges of the approach plates being strip-shaped and running in a common horizontal plane.
  • the approach plates are only connected to each other in the area of their ridge edges.
  • the guiding thresholds are to maintain their positional stability by means of projections which are punched out in the transition area from the horizontal edge areas to the curved longitudinal sections of the approach plates and bent vertically downward. These projections are to be driven into the respective floor either by the dead weight of the guiding thresholds, by deliberate impact force or also by the weight of the motor vehicles when they drive onto the horizontal edge regions.
  • the known guiding threshold string can only be used to a limited extent where two lanes are to be separated from one another or where z. B. construction sites must be secured against an adjacent lane.
  • the guide thresholds can slip especially when they are arranged on hard concrete floors.
  • no constant longitudinal alignment is possible.
  • Protrusions can form in the area of the butt joints between two guide sleepers, hit against the motor vehicles and can then laterally shift the guide sleepers from the desired position to an increased extent.
  • Another disadvantage is the fact that the guide sleepers are connected to each other only in the ridge area of the approach plates. Your torsional stability is therefore low.
  • the approach plates are set relatively steeply, in principle they only form deflectors which cannot return the vehicles that have strayed from a carriageway to the carriageway relatively smoothly.
  • the invention is based on the guide threshold strand described in the preamble of claim 1, the problem of designing it so that it requires only a small footprint with sufficient stability and torsional stability and still ensures a perfect deflection function.
  • An essential feature of the invention is the uniform curvature of the starting plates. Since the guiding thresholds are generally used where relatively low speeds are used, the curvature of the approach plates that gently opens into the carriageway ensures that vehicles rolling onto the approach plates are automatically redirected and smoothly onto the carriageway without the risk of damage to the body to be led back. This diverting function has a particularly noticeable effect where oncoming traffic on narrowways, in particular in the area of bridges, is to be separated in construction site areas on motorways.
  • the guide threshold line according to the invention can also advantageously be used where median crossings have to be opened quickly. Traffic diversions in urban areas can now also be designed easily and simply using the guide threshold line according to the invention. Furthermore, a safe separation of temporary parking and parking spaces can be carried out without any problems.
  • Another advantage of the invention is the easy handling of the guide sleepers despite the compact stability with sufficient stackability. As a result, short assembly times only result in short-term traffic restrictions. A guardrail can easily be handled by two fitters.
  • the lower longitudinal edges of the approach plates can also be slightly convexly curved towards the ground, with the largest possible radius of curvature. This prevents damage to softer roads.
  • the same function can also be performed by rubber covers on the longitudinal edges of the approach plates. In addition, such rubber covers increase the coefficient of friction between the approach plates and the road surface.
  • the coupling tubes above the guide sleepers create a rounded upper end of the guide tie line, which is of particular benefit to two-wheelers who have come onto the guide tie line, and here, in particular, to motorcyclists.
  • the ridge-side plug-in connection in the axial direction of the coupling tubes contributes to the correct alignment of the guide threshold line, even when a motor vehicle strikes a guide threshold more strongly. Nevertheless, the coupling is held in such a way that all curve routing necessary in practice can be guaranteed.
  • the plug pin can be formed directly by the open inner cross-section of a coupling tube, the end faces of which run in one plane with the end faces of the adjacent start plates
  • the plug pin consists of a separate solid or tubular material, the end faces of the start plates at the other end of the coupling tube projecting is provided.
  • the plug pin is preferably also formed from a piece of pipe which is fastened, in particular welded, in the coupling pipe.
  • the spigot can be conical to improve cornering.
  • Another advantage of the invention is that the application of road markings can be omitted. It is conceivable, for. B. the application of markings in the bottom area of the approach plates. A white and red marking on the loading plates can also be possible with an additional PVC coating.
  • the features of claim 2 serve to achieve a prescribed minimum height of the guide threshold strand, but without neglecting the rounded upper edge. It also allows the preferred inside and outside diameter Identically connect the ridge tubes corresponding to the coupling tubes using the locking bolts to connect the guide sleepers to each other in a tensile and compressive manner. With this type of coupling, it is not necessary when assembling a guide threshold strand to have to handle screw connections or other connections that require special tools.
  • the ridge and coupling tubes overlap by about half their straight length. To improve cornering, the locking bolts can grip the recesses in the coupling tubes with a corresponding clearance.
  • the centering pins and centering sleeves additionally serve for the safe alignment of all guide sleepers integrated in a guide tie line.
  • this can also be short pieces of pipe which correspond to the dimensions of the coupling pipes or the ridge pipes in terms of the inside and outside diameter.
  • the centering spigot is also a piece of pipe that corresponds to the spigot of the coupling pipe.
  • the pin receptacles and the centering sleeves on the one hand and the plug pins and the centering pins on the other hand each lie vertically one above the other at the ends of the guide sleepers.
  • the centering pins and centering sleeves are preferably fixed between the approach plates by welding.
  • the centering pins can also be conical, if necessary, to improve cornering.
  • the ridge tubes with the locking bolts assigned to them also pass through corresponding vertical recesses in the centering pin and in the centering sleeves, the guide sleeper strand is stabilized even more overall and less sensitive to a stronger impact.
  • the locking bolts can still play through the recesses in the centering pin and in the centering sleeves to increase cornering.
  • the transverse webs can be provided on their lower edges with horizontal feet, which on the one hand prevent the longitudinal edges of the approach plates from being pressed into the carriageway and on the other hand improve the coefficient of friction between the carriageway and the threshold line.
  • the foaming of the cavity between the approach plates according to claim 7 is associated with the advantage that the coefficient of friction to the floor is thereby improved.
  • 1 denotes the section of a guide threshold line, as can be used, for example, to separate oncoming traffic in a narrow lane in a construction site area of the motorway.
  • the guiding threshold line 1 consists of guiding thresholds 2, which are placed one after the other, of identical design. Its length L is, for example, 2000 mm. The total height H and the maximum width B each amount to 500 mm (see also FIG. 2).
  • each guide threshold 2 has two approach plates 3 which are concavely curved in opposite directions in the vertical cross section.
  • the approach plates 3 are evenly curved over their entire height, i. H. they have an identical radius. They are stiffened by three triangular cross webs 4 arranged vertically at a distance from one another.
  • the transverse webs 4 are arranged in the approximately central longitudinal section and at a short distance from the two end faces 5 of the approach plates 3.
  • the crossbars 4 are connected to the starting plates 3 by welding. Furthermore, it can be seen in particular from FIG. 2 that the transverse webs 4 end with their lower longitudinal edge 6 just above the plane HE tangent to the lower longitudinal edges 7 of both approach plates 3.
  • the lower longitudinal edges 7 of the approach plates 3 open tangentially into the common horizontal plane HE, which also forms the road surface.
  • the upper longitudinal edges 8 are fastened on the underside of a coupling pin 11 formed at one end by a plug-in pin 9 formed from a tube piece and at the other end by a coupling tube 11 having the pin diameter 10 formed by the inner diameter.
  • the length of the coupling tube 11 corresponds to the length of a guide sleeper 2.
  • the plug pin 9 projects beyond the end faces 5 of the approach plates 3.
  • the butt joints 12 of two guide rails 2 bridging ridge tubes 13 are provided above the coupling tubes 11, which can be taped together in the longitudinal direction.
  • the cross section of the ridge tubes 13 corresponds to that of the coupling tubes 11. Their length also corresponds to the length L of the guide sleepers 2 or the coupling tubes 11.
  • the ridge tubes 13 are provided with locking bolts 14, 15 directed downwards. These locking bolts 14, 15 can consist of solid or tubular material.
  • vertical recesses 16 are provided both in the area of the plug pins 9 and the pin receptacles 10 and in an area in between, which are adapted in cross section to the locking bolts 14, 15.
  • FIGS. 1 and 2 show that centering pins 17 and centering sleeves 18 pointing in the longitudinal direction in the area below the coupling tubes 11 are fastened between the starting plates, in particular by welding.
  • the centering pin 17 and the centering sleeves 18 are also tubular. They correspond in cross-section to the plug pins 9 and the pin receptacles 10 of the coupling tubes 11. Their length is such that the centering pins 17 are inserted correctly into the centering sleeves 18 of adjacent guide sleepers 2 and can ensure the axial alignment of the guide sleepers 2 together with the coupling pipes 11.
  • the locking bolts 14, 15 of the ridge tubes 13 have different lengths.
  • the locking bolts 15 provided in the region of the plug pins 9 and pin receptacles 10 are dimensioned so long that they also penetrate corresponding vertical recesses 19 in the centering pin 17 and in the centering sleeves 18.
  • Figure 1 shows that in the vicinity of the lower longitudinal edges 7 of the approach plates 3 drain holes 20 are provided on both sides of the crosspieces 4. Water can pass through these drain holes 20.
  • transverse webs 4 end with their upper edges 21 just below the coupling tubes 11.
  • Figure 3 it is shown that the guide sleepers 2 are stackable.
  • two thresholds 2 are arranged side by side, a third threshold 2 is rotated by 180 ° about its longitudinal axis and then inserted between the two thresholds 2 from above.
  • 3 longitudinal or transverse markings 22 in the form of at least one adhesive tape or firmly applied granulate can be provided in the bottom area of the starting plates 3.
  • the granules can then, for. B. have properties as it owns the adjacent lane 23.
