Description

The invention relates to a guide rail string made of steel for motor vehicles according to the features in the preamble of claim 1.

Such a guide threshold line forms the scope of EP 0 472 847 B1 of the technique. The at the ends of the base body and the guide rails of the guide thresholds The intended locking devices consist of the basic bodies and housing-like consoles assigned to the guide rails at one end, in the ends of neighboring base bodies and guide rails in the axial direction be inserted, as well as from sigma-shaped plug pins, which are in vertical Direction from above by adapted to the cross-section of the plug pins Recesses at the ends of the guide rails and base body as well as in the Consoles are introduced.

The known plug lock has proven itself in practice in principle. Yet practical use has shown that the inevitably necessary Play between the pins and the recesses in the guide rails, the base bodies and the consoles in the event of a rear-end collision can lead to two successive guiding thresholds being too strong to each other kink and this causes the guardrail string to be shifted too far to the side and this can result in an impermissibly large "bag formation". Such one "Sack formation" can then occur on a median between two Roadways with two-way traffic used guide rail that the guardrail line is shifted to the other lane so that it further accidents can occur here. On the other hand, it can be prohibited by an Large "bag formation" occurs that the impacting vehicle not guided along the guide threshold line as desired, but not only in your own lane, but possibly also in a parallel one existing lane is thrown. Here too there can be more Accidents are coming.

Furthermore, it has proven to be in need of improvement in the known guide threshold line emphasized, in particular the dismantling after a rear-end collision to facilitate. Due to the fact that the individual thresholds with regard to the base body and the guide rails in the axial direction limited exchange of guiding thresholds is one closed guardrail line only possible if one or two Guide thresholds must be completely destroyed because of the axial scope for Pull apart does not exist. Also the reinstallation of new guiding thresholds into an otherwise closed guide-rail line has considerable problems.

The object of the invention is based on the prior art to create a steel guardrail string for motor vehicles, the faster to assemble with respect to the individual guiding thresholds and after Rear-end collisions are to be dismantled, and which of the required in rear-end collisions Safety standard both when used on verges of roadways as well as when used on median strips.

This object is achieved with the in the characterizing part of claim 1 specified features solved.

Through the angle profiles in cooperation with the front coupling bars are now two successive guiding thresholds of a guiding threshold line secure with each other only by hanging in the vertical direction tensile and pressure resistant connected. For this purpose, at one end are each Base body and each Leitholms angle profiles with upward Vertical legs are provided, behind which the coupling webs then face of the neighboring base body or guide rail. On the other hand, border downward vertical web of an angle profile at the other end of a Base body from above behind a coupling web, which is in the lower height range carries an angle profile with the vertical leg directed upwards. For this purpose, one is in the cover plate of the base body to the angle profile provided with a recess that is adapted to the vertical leg pointing downwards.

The plug or hook lock according to the invention between two guide thresholds not only ensures easy installation of guide rails Leitschwerschstrangs but also easy disassembly, for example after a rear-end collision. To assemble, the game of locking be kept comparatively tight, so that the dreaded "bag formation" is avoided in a rear-end collision. After a rear-end collision can be damaged Guiding thresholds easily removed upwards and with new guiding thresholds be replaced.

Form the angle profiles and according to the features of claim 2 Coupling webs components from in the end sections of the base body and Leitholme releasably inserted housing adapters, so the invention Locking even with such guide thresholds already in use be used using a given Hole pattern over plates in the area of the base body or short plug housing in the Area of the guide rails are connected to each other by screws. On in this way, the known guide thresholds can be converted and thus the required better assembly and disassembly conditions and a higher Security standard are supplied.

To stiffen the angle profiles are according to the features of the claim 3 between the horizontal leg and the vertical leg gusset plates incorporated. These gusset plates are preferably located to the side of the angle profiles. However, at least one further gusset plate in the middle is also conceivable Angle profiles. To the angle profiles formed in this way perfectly to the Weld base bodies and also on the guide rails and also around the Move the coupling webs perfectly over the vertical legs of the angle profiles in the coupling webs, especially the base body, vertical slots extending from the lower and upper horizontal edges incorporated into which the gusset plates then engage.

In a further embodiment of the basic idea of the invention according to claim 4, the vertical legs of the angle profiles fitting plates releasably assigned. These fitting plates are initially with the Screwed vertical legs. When connecting two guiding thresholds achieved a low backlash longitudinal alignment of a guide threshold strand. Should however, the guide threshold line is laid in a curve is a corresponding one Game required, which is then removed by removing the latches at least one fitting plate is reached.

It can be used to deliberately bend two successive guiding thresholds according to claim 5 also make sense, the fitting plates in the horizontal Form cross-section wedge-shaped.

Because the inclined riot plates of the base body are usually made out comparatively thin steel sheets could exist in the joint area of two If the terrain is unfavorable, the riot plates if necessary overlap at the ends. To prevent this possibility, see the features of claim 6 before that at the ends of the riot plates with their End-side filler pieces are provided. Because the riot plates laterally sloping downward, are now in the joint area two guide rails on the riot plates relatively large front Support surfaces created that avoid overlapping.

In a development of the invention, it can also be useful according to claim 7 be, also the adjacent ends of successive riot plates to couple with each other. For this purpose there are riot plates at one end angular hooks provided, the horizontal leg are attached to the underside of the support plates and their upwards directed vertical leg at a distance in front of the end faces of the guide sleepers lie. At the other ends of the riot plates are at a distance from the Cutouts adapted to the vertical legs are provided on the end faces.

When installing two guide rails, the vertical legs of the Hooks from below into the cutouts in the support plates so that two successive guiding thresholds not only in the area of the guide rails and the base body, but also the support plates are coupled in a tensile and compressive manner are.

In unfavorable terrain, it can correspond to the feature of the claim 8 also be useful, the horizontal leg of the hook to be screwed to the ends of the neighboring support plates. To this Purpose can between in the horizontal legs and in the riot plates holes are provided in the end faces and the recesses, which are interspersed with vertical bolts.

Finally, it can also be advantageous according to claim 9, even the Coupling webs of successive guide rails by at least each to connect a horizontal bolt to the axial alignment of a leading threshold line (escape).

In FIG. 1, 1 is a steel guide rail string for motor vehicles referred to, for example, on a median between two lanes is arranged with oncoming traffic. The lanes are with the arrows F1 and F2 marked.

The threshold line 1 consists of identically detachably placed one against the other trained thresholds 2, 2a etc. The number of thresholds 2, 2a etc. corresponds to the length of the desired separation of the two lanes F1 and F2.

As can be seen from a joint examination of FIGS. 1 and 2, each threshold 2, 2a a housing-like base body 3, 3a with a roof shape inclined side approach plates 4, one the upper longitudinal edges 5 of the approach plates 4 connecting cover plate 6 and on the lower longitudinal edges 7 the approach plates 4 wing-like support plates 8, 8a and with the base bodies 3, 3a via vertical posts 9 with a sigma-shaped cross section connected in parallel, perpendicular distance, C-shaped in cross section, guide rails 10, 10a open at the bottom. The base body 3, 3a can with the approach plates 4, the cover plates 6 and the support plates 8, 8a be formed from a board. It is also conceivable that the approach plates 4, the cover plates 6 and the support plates 8, 8a form separate components which are welded together at their longitudinal edges 5, 7.

The guide thresholds 2, 2a are in the height range of the support plates 8, 8a Cross channels 13 penetrated, which allow water to flow through (FIG 1).

As can be seen in particular in FIG. 1, the end faces 11, 12 meet the guide thresholds 2, 2a butt against each other. So that on a wavy surface the ends of the support plates inclined to the contact area 8, 8a do not overlap, are at the ends of the support plates 8, 8a with their Bottom end pieces 14 welded on the end faces (FIG. 2).

In the transverse planes of the end faces 11, 12 of the guide sleepers 2, 2a are in the height range the starting plates 4 coupling webs 15, 15a into the base body 3, 3a welded (Figures 1 to 3). From the lower and upper horizontal Edges 16, 17 of the coupling webs 15, 15a extend from vertical slots 18, 19 in the coupling webs 15, 15a.

At one end of each base body 3, 3a is in the lower height range Angle profile 20 with a horizontal leg 21 and a vertical leg 22 welded. The vertical leg 22 extends from the horizontal leg 21 from up. On both sides of the angle profile 20 are between the Horizontal leg 21 and the vertical leg 22 welded gusset plates 23. The gusset plates 23 extend through the vertical slots 18. Figure 2 also shows that also in the middle length range of the angle profile 20 a gusset plate 23 can be provided. This too between the Horizontal leg 21 and the vertical leg 22 welded gusset plate 23 extends through a vertical slot 18 in the coupling web 15 and after locking also through the vertical slots 18 in the coupling web 15a.

At the other end of the base body 3, 3a is an angle profile 24 with its Horizontal leg 25 welded under the cover plate 6 of the base body 3, 3a. The vertical leg 26 points downwards. Between the vertical legs 26 and the horizontal leg 25 are lateral gusset plates 27 welded through the vertical slots 19 of the coupling web 15, 15a extend.

FIGS. 2 and 3 also show that the cover plates 6 are the base body 3, 3a is recessed at the end above an angle profile 20, wherein this recess 28 on the angle profile 24 with the 'downward vertical leg 26 is adjusted. The coupling web 15 is also at the top here Except for the end, which depends on the thickness of the horizontal leg 25 of the Angle profile 24 is adjusted.

Also in the transverse planes of the end faces 11, 12 of the guide sleepers 2, 2a Coupling webs 29, 29a welded into the guide rails 10, 10a (FIGS. 2 and 3). Bores 30, 30a are located in the center of the coupling webs 29, 29a. If two guide thresholds 2, 2a are joined together, then through these holes 30 a coupling pin 31 is inserted, which of the tensile and pressure resistant Connection of the guide bars 10, 10a is used.

At the end of a guide rail 10, 10a, which is above the end of the base body 3, 3a is where the cover plate 6 has a recess 28 is an angle profile 32 welded with a horizontal leg 33. The vertical leg 34 points upwards.

When joining two guide thresholds 2, 2a only one is required End of the guide threshold 2a, which is provided with the angle profile 24, the Vertical leg 26 points downward, from above to the other guide threshold 2 to be applied that the coupling web 29a in the guide rail 10a between the vertical leg 34 and the coupling web 29 in the guide rail 10 summarizes and that the vertical web 26 of the angle profile 24 in the upper height range of the base body 3a through the recess 28 and behind the coupling web 15 summarizes, while the coupling web 15a of the base body 3a between the vertical leg 22 and the coupling web 15 in the lower height range of the base body 3 summarizes.

Then the coupling pin 31 can still through the coupling webs 29, 29a of the guide rails 10, 10a are inserted and fixed.

An embodiment is illustrated in FIG. 3, in which the end the support plates 8, 8a angular hook 35 with their Horizontal legs 36 welded below the support plates 8, 8a are. At the opposite ends of the support plates 8, 8a are in Distance from the end faces 12 recesses 37 are provided, which to the Configuration of the vertical legs 38 of the hook 35 are adapted.

When two guiding thresholds 2, 2a are joined, the vertical legs then grip 38 from below into the recesses 37, so that the guiding thresholds also here 2, 2a are connected tensile and compressive.

If the area where the threshold line 1 is to be installed is uneven is, in addition, a hole 39 in the area of a riot plate 8, 8a between the end face 12 and the recess 37 on the one hand and another bore 40 in the horizontal leg 36 of the hook 35 on the other hand. Then there are two guiding thresholds 2, 2a joined together, a bolt 50 is through the holes 39, 40th inserted and fixed in position.

FIG. 4 shows an embodiment in which the vertical leg 34 a fitting plate 41 is associated with the angle profile 32 of the guide rail 10. A such a fitting plate 41 can also on the angle profiles 20 and 24 Base body 3, 3a are provided.

In dash-dotted lines it is illustrated that - in the horizontal Cross section seen - the fitting plate 41 can also be wedge-shaped.

These fitting plates 41 are used for a curved installation of a threshold line 1 the curve-shaped course without relevant play sure.

The fitting plate 41 shown is screwed to the vertical leg 34 on the inside. Then the distance between the fitting plate 41 and the neighboring one Face 11 of the guide spar 10 so that a straight alignment of two Adjacent thresholds 2, 2a is guaranteed without substantial play. at the curve plate 41 is removed or by a thinner fitting plate 41 replaced. In this way, the opposite Guide bar 10a can then be set at an angle to the guide bar 10 shown.

Screw bolts 42 serve to fix the fitting plate 41 on the vertical Leg 34 of the angle profile 32.

FIG. 5 illustrates an embodiment of a guide threshold line 1a, in which the measures explained above with reference to FIGS. 1 to 4 can also be carried out with guide thresholds 2b, 2c, which on their ends 44, 44a with respect to the starting plates 4a of the base body 3b, 3c, the support plates 8b, 8c and the guide rails 10b, 10c only by means of the support plates 8b illustrated plates 43 and not shown, through holes 45 pluggable screw bolts detachably coupled together become.
