The invention relates to a track, the rails of which laterally and down over elastic intermediate pads under the Headboard on the inside and outside of the rail Side rails are supported, with the rails at a distance run over the underlying track components, and a extending base plate is provided under the rails.

To reduce the occurrence of tracks Shocks and the structure-borne noise generated with it has been proposed for a long time elastically mounted rails. So e.g. described in WO 92/04503 a track substructure, at which the rails on elastic intermediate layers on profile rails are supported as side members that are attached to the and arranged inside the rail and with underlying Beams made of precast concrete are connected, whereby the space below the foot of the rail is free. The Beams are connected to each other by cross struts. The Profile rails have a multi-curved cross-sectional profile and are clamped together with screws, which are passed through the rail web. The structure this track is therefore complex because a plurality of to Part of complicated shaped components is required, the Assembly also requires a lot of time.

Also with a track known from the generic BE 903 871 A. is a relatively complicated structure before, which also requires a lot of effort in assembly. At this known track are the rails by means of elastic Intermediate layers, which the head part of the rails on both sides reach under supported on longitudinal strips, which in a groove a concrete slab are inserted. This concrete slab is in place and poured spot.

To reduce the effort in components and time According to the invention provided that the side members on the Rail outside of the first console strips that are part of the are under the rails extending base plate, and that the Side rails on the inside of the rail, second console strips are part of an inner plate lying between the rails are, which in turn is supported on the base plate. The Inner plate can be designed as a frame.

An advantageous embodiment of the invention exists in that the base plate on the outside of the rail upwards has protruding side parts on which the first console strips are integrated, and that the second Console strips on the side ends of the inner plate or - frames are integrated.

To the load on the base plates and the inner plates to divide evenly, and to collapse joints the base plates with the joints of the inner plates avoid, you can advantageously provide that the base plate and the inner plate have the same length and half Length are offset from each other.

For better static and dynamic transmission of Forces between inner plates and base plates, it is advantageous if the base plate and / or the inner plate at least a longitudinal rib to support the inner plate on the base plate has or have, preferably between the Longitudinal rib of the base plate and the inner plate or between a longitudinal rib provided on the inner plate and the base plate an elastomeric band is arranged so that a sound absorbing Effect and an elastic bedding is achieved.

Another advantageous embodiment is characterized in that that the base plate two at a distance from each other arranged and directed upward longitudinal ribs, the interrupted in the middle or reduced in height are, and that the inner plate at its end regions two with the Longitudinal ribs of the base plate have aligned longitudinal ribs. This ensures that there is no mutual displacement the base and inner panels can take place in the longitudinal direction.

1, 1 generally designates a track with rails 2, whose head part 3 each on the outside of the rail via an elastomer profile 4 on a console bar 5, and each on the Inside of the rail via an elastomer profile 6 on a console bar 7 is supported. The elastomer profiles 4, 6 extend itself from the head part 3 to the foot part 8, the elastomer profiles 4, 6 are pressed together by the console strips 5, 7, so that the rails 2 are fixed in the lateral direction.

The two console strips 5 are on the outside of the rail on upwardly projecting side parts 9 one below the rails 2 lying base plate 10 which is rectangular in plan arranged integrated. The two are similar Console strips 7 on the inside of the rail integrated on the lateral ends one between the rails 2 and above the Base plate 10 lying, rectangular inner plate in plan 11 arranged, which are on the elastomer bands 12 on the Base plate 10 supports. As can be seen from FIGS. 2 and 3, have the base plate 10 and the inner plate 11 the same Length, but are offset by half a length to each other arranged. To a mutual displacement of the plates 10, 11th to prevent, each base plate 10 has two spaced apart arranged and upwardly directed longitudinal ribs 13 that are interrupted in the middle area or reduced in height are a recess for receiving longitudinal ribs 14 to form at the end portions of the inner plate 11 aligned with the longitudinal ribs 13 and directed downwards, the longitudinal ribs 13, 14 at the mutual transitions to the respective plate body of the base plate 10 or the inner plate 11 trained obliquely and so in height are dimensioned so that a space for receiving the elastomer bands 12 lying between the longitudinal ribs 13, 14 is formed. With this design, the longitudinal ribs engage 13, 14 when assembling the plates 10, 11 in the between the Longitudinal ribs formed complementary projections and recesses like a toothing and form a positive Longitudinal connection.

The base plates 10 and the inner plates 11 can be used as Finished parts are manufactured, preferably reinforced concrete, Polymer concrete or special concrete, e.g. with additives, used is, and the plates 10, 11, if desired, with one reinforcement shown can be provided. The base plate 10 can also be manufactured in in-situ concrete. Furthermore are the plates 10, 11 to save material in the middle each provided with a rectangular recess 15 or 16, to which the longitudinal ribs 13 and 14 connect laterally. By the recesses 15 and 16 give the plates 10, 11 the shape of a frame, possibly with a closed bottom is provided. Furthermore, the base plate 10 to increase the load capacity one of the side parts 9 outgoing and reinforced reinforcement 17, as indicated in FIG. 4 with dash-dotted lines is. To the load capacity of the base plate 10 in addition can increase the space between the two ribs 13 in the area outside the recess 15 filled with material at the same level as shown in Fig. 4 with two-dot chain lines is. The same measure can be taken for the inner plate 11 be provided.

In order to determine the electrical potential of the base plate 10, are preferably 9 angle profiles at the upper end of the side parts 18 made of metal, which are conductively interconnected and / or can be grounded.

In Figure 5, a rail 2 'is shown, which instead of one Foot part has a second head part 3 ', so that the rail 2 'after excessive wear, especially on the flange side, removed and reinstalled upside down can. Each rail 2 'can thus be used a total of four times Find.

Fig. 6 shows an arrangement in which the height of the elastomer profile 4 'on the outside of the rail below the head part 3 greater than the height of the elastomer profile 6 'on the inside of the rail is to the deflection of the elastomer profile 6 'and to compensate for the elastomer bands 12. At the same time, through suitable choice of the height of the elastomer profile 6 'an inevitable Tilt the rail 2 to the inside, as by the second inclined central axis shown in FIG M is indicated, so that the rails are tapered adjust turned treads of a wheel tire and none The flange is worn.

For safety and revision reasons, the rails are 2 in Distances of 10 to 60 m at fixed points rigid with one Foundation 19 connected, as shown in Fig.7.

Serve to connect the rails 2 to the foundation 19 for example four metal plates 20 anchored in the foundation which conventional rail fasteners 21, e.g. Clamping plates, spring clips or the like are attached to the Pinch rails 2. The length of the foundation can be about 0.5 up to 1 m. This arrangement prevents emigration Rails 2 prevented in the lateral and longitudinal directions.

8 is the foot part formed as a bead 23, the two elastomer profiles 4 " and 6 "each have a width when removed that equal to half the distance between the two console strips 5 and 7. The two elastomer profiles 4 "and 6" can also be formed in one piece by their lower end are connected as shown with dashed lines is. In the transition area are then arranged at a distance Openings 24 are provided which allow an air outlet or air inlet allow when installing and removing the 2 "rail.

For street crossings at the same level, that is at least Inner plate 11 executed without opening 16. For execution of arcuate track sections, the base plate 10 has in Outline the shape of an isosceles trapezoid while the inner plate 11, each of which is two halves of the base plates 10 overlaps, correspondingly a shape of two in the floor plan composite uneven-legged trapezoids.

To install the rails 2, 2 'between the base plate 10 and Inner plate 11 are on the side parts 9 of the base plate 10 On the inside, central recesses 22 are provided for insertion an insertion tool, e.g. the jaw of a pair of pliers, enable. For the same purpose, the inner plate 11 recesses 22 'are provided on the outside, which are shown in FIG dashed lines are shown. In addition, the Base plates 10 at the joints with a recess 22 ' similar to the recess 22 in the middle or with wider, be inclined recesses 22 "', wherein the latter for easy insertion of the elastomer profiles 4, 4 ' serve for assembly (see Fig. 2). For an axial migration of the Preventing elastomer profiles 4, 4 'are in the area of the recesses 22 "'clamps (not shown) arranged. To reduce the running noise of the wheels can on the Side parts 9 of the base plate 10 walls 25 made of sound-absorbing Material can be attached on one or both sides (see Fig. 2). In the area of the recesses 22, the elastomer profiles 4, 4 ' and the console strips 5, 5 'interrupted.

When installing, the elastomer bands 12 are first on the Longitudinal ribs of the base plate 10 placed and the rails 2, 2 ' with pliers to the console strips 5 of the base plate 10 pressed, whereupon the inner plate 11, possibly in an inclined position, is used in the base plate 10. Now the elastomer profiles 6, 6 'between the console strips 7 of the inner plate 11 and the rails 2, 2 'inserted in the track direction. Subsequently the rails 2, 2 'from the outside with the pliers pressed together and the elastomer profiles 4, 4 'preferably over the recesses 22 "'between the console strips 5 of the Base plate 10 and the rails 2, 2 'inserted or moved in.

In a second type of installation, the Elastomer profiles 6, 6 'on the console strips 7 of the inner plate 11 attached and then the rails 2, 2 'outside to the Elastomer profiles 6, 6 'created. Then the rails 2, 2 ' pressed together from the outside by means of the pliers, so that the Distance between the rails reduced. Then will this assembly between the console strips 5 of the base plate 10 used, in which the elastomeric bands 12 previously on the Longitudinal ribs 13 were placed, the pliers jaws in the Recesses 22 occur, whereupon the elastomer profiles 4, 4 ' the console strips 5 of the base plate 10 by insertion be attached. After the pliers are released, the rails 2, 2 'clamped, whereupon the pliers jaws from the recesses 22nd be pulled out.

A third way of installing the rail 2 "according to Fig.8 in that the elastomer tapes are inserted first and the Inner plates 11 is inserted into the base plate 10, then the rails 2 "on both sides with the elastomer profiles 4, 4 'and 6, 6' are provided, whereupon this unit if necessary with the interposition of a sheet metal strip between the Console strips 5 and 7 are pressed under pressure from above.

A fourth way of installing the rails 2 "according to Fig.8 in that first the elastomer profiles 4, 4 'and 6, 6' the console strips 5 and 7 are attached, whereupon the Rails 2 "pressed under pressure from above and through the bead 23 can be secured in this position.

Since there are different shapes of rail profiles, you can the console strips 5 and 7 or the elastomer profiles 4 and 6 the headboard, bridge and footboard of these profiles can be adjusted.

The distance between the console strips 5 and 7 to the top of the Base plate 10 is selected so that the foot part 8, 8 'of the rail 2 always, also in the case of load, at a distance from the top the base plate 10 extends. The inclination mentioned above the rail 2 can also be achieved in that the distance the console strips 5 on the outside of the rail to the top the base plate 10 is greater than the distance between the console bar 7 on the inside of the rail to the top of the base plate 10 is chosen.

For the production of rails with reduced width of the Rails with normal profile can be used, the foot part by cutting with a cutting torch or laser reduced to the required width on one or both sides becomes.

The elastomer profiles 4, 4 'and 6, 6' can either be cut to length inserted or used with each plate unit a lubricant inserted over the recesses 22 "' or to be confiscated.
