Level crossing at the same level as the rails

The invention relates to a rail-like level crossing made of at least three plates forming part of the roadway, which on the rail side of the rail profile adapted fittings held each plate with the corresponding fitting (s) Is held immovable in the longitudinal direction.

Such level crossings have been known for a long time, with the plates made of steel, steel-reinforced concrete or the like, the shaped pieces made of wood, rubber or the like.

Previous designs, however, had two difficulties to struggle with the constant stress of being run over

409812/0380

of the level crossing by the ZUge on the one hand, by the motor vehicles on the other hand. Fittings made of wood are subject namely a relatively quick destruction by the vibrations, while rubber ones tend due to their elasticity to under the influence of most of the time at a given level crossing Tensile or compressive forces acting in a certain direction from the originally intended for this area between plate and rail to wander out

This tendency can be seen in wooden wedges by a particularly strong one Counteract the clamping effect, but such fittings, as mentioned, only have a short service life. In the case of molded parts made of rubber one has It has already been proposed to improve the clamping effect in that part of the surface of the molding on the rail side is grooved and the molding is optionally arranged on the plate lateral boundary walls is held. However, such a construction does not offer absolute security against in all cases wandering out

Also known are positive connections of plates and Fittings such as tongue and groove, pegs, screw connections, etc.

These connections have the disadvantage that, for example, in the case of the specified, longitudinally leading groove with a tongue, there is no positional securing in the longitudinal direction of the rails. This results in a slow shifting of the plates in the longitudinal direction of the rails

The pegs used for a fixation loosen with permanent ones Vibrations and, due to their thermal expansion coefficient, which differs from that of the plate and fitting, screw connections have the advantage of exact fixation of plate and fitting, but have the disadvantage that a possible exchange of a plate, especially if the screws are corroded and rusted, take a long time and are therefore very

seems disabled.

or Sch

In addition, the fixation by means of pegs or screws required holes in the plate and in the fitting weakened the material.

To eliminate the problem mentioned, it is therefore proposed according to the invention that the mutual anchoring is exclusively

the Äu & ullJuiiy u'wi ueiuöii coming to lie on top of one another Areas of the plate and the shaped piece which are designed to be anchored to one another, for example by the arrangement of a Adhesive layer and / or of interlocking projections and recesses, with the plate and the shaped piece optionally being supported together on the rail fastening devices. The invention is based on the knowledge that the Plate (s) generally without too much problems on the devices with which the rails on the sleepers or the other substructure are attached, supported and thus secured against displacement in the longitudinal direction of the rails (can). It is therefore generally sufficient for the fittings in turn to connect with the plate essentially immovable in order to counteract the walling out of these shaped pieces from the intended space. This creates a secure connection created, which allows a damaged plate to be replaced without spending a lot of time.

In many cases it has been found useful that the Form piece has a recess with lateral boundary walls, the latter preferably in the form of metal plates.

For this purpose, the molded piece is then preferably produced as a metal-rubber composite body, the plate with at least part of its overlying edge region protrudes into the recess thus formed by the shaped piece, or the side walls provided on the shaped piece protrude into corresponding recesses on the plate. In this way

vibrations caused by vehicles are dampened in the best possible way * This also increases the service life of the individual Plates considerable.

The invention is illustrated below with reference to the drawing explained in more detail. Show it:

1 to 4 and 6 each show an embodiment according to the invention of the connection between plate and shaped piece / each in sections in an oblique view;

5 shows another embodiment according to the invention in section; ■ Fig. 4a and Fig. 6a each have a connecting element in an oblique view.

Fig. 1 shows a plate 1 for the level crossing in sections in an oblique view, which has step-shaped recesses 3 on the underside. These are laterally bounded by projections 4. These projections 4 in turn lie in the recess 5 of the molded piece 6 provided for the support 6 are vulcanized in as a metal-rubber composite. In order to absorb the forces acting vertically on the platelets, which occur especially when the level crossing is not crossed at right angles, it is of great importance that the strength of the metal-rubber bond is sufficiently high.

In these recesses, two or more cylindrical ones protrude Parts od · (pegs) 8, which engage in through bores or blind holes 9 of the molded piece 10. The pins 8 have a Distance b, which corresponds to the distance b of the holes 9. These

Fastening design ensures a secure fixation in position between the rail, shaped piece and plate, and not only in the longitudinal direction of the rail, but also perpendicular to it.This is how the fitting 10 is through the projections 4 in the longitudinal direction of the rails and through the pins Attached lengthways and crossways. When driving over the level crossing there is therefore no displacement of the plates located between the rails.

In the embodiment according to FIG. 3, a protrudes from the recess 3 Bulge, which can also be referred to as a spring 11. The molded piece 12 used as a support has a groove 13 into which the Spring 11 engages. This results in a very good positional fixation even if the level crossing is not crossed at right angles. Due to the increased contact area between tongue and groove, there is also no longitudinal displacement between the plate and the fitting. If a continuous bulge is provided (without the projections 4), this can also be done in conjunction with another according to the invention Embodiment, for example according to FIG. 6, can be achieved.

Fig. 4 shows the plate 1 with the shaped piece provided as a support 14 and the resting of the shaped piece 14 on the rail 15. By a bracket 16 made of steel or another functionally appropriate Material, which has one or more transverse ribs 17, is connected to the plate with the molding. There are still in the plate Recesses 18 at a point where the transverse ribs 17 of the brackets 16 engage. There are also recesses in the fitting for this purpose intended. A secure fixation in position is given by this execution. In addition, the individual elements can be exchanged quickly and easily, which are also produced quickly, easily and cheaply can be relocated.

between plate 1 and shaped piece 20. The connecting piece is a conical bolt 21 made of metal, rubber / plastic or other material. In the plate 1 there is a conical bore 22 which, at the upper end, is greatly enlarged in increments compared to the conical course * in the rormstucK i \ j oeTinuet sicn uio r ui. ufeeiZüng oer uuurung * - * -, namely hole 23, for the conical bolt 21 · The fixation of the bolt 21 in the bore 23 takes place by one or more annular bulges 24. These bulges 24 have the purpose of the bolt 21 by their clamping effect to be held in the bore 23. This enables panels and forest pieces to be installed quickly and safely. The situation is thus sufficiently fixed. Several bolts 14 can also be used one behind the other.

Fig. 6 shows a rail level crossing according to the invention in an oblique view. The field 25 between the rails 15 is filled by a plate and fittings (not visible in the drawing). Through a Angle iron 26, which is screwed to the rail fastening 27, the plate 1 is trimmed at the end of the level crossing and in fixed in their position. V / eil of this angle iron 26 with an arm (28) too rests on the rail 15, there is koinem twisting of the angle iron around the pivot point of the rail fastening 27. Therefore, the angle iron is sufficient 26 only to be attached to one point

The plate 1 can therefore firstly be easily dismantled and also installed will. Complete fixation occurs during use.

In addition, a sheet metal strip 31 protrudes on the side 27 , which has a bore 32 which is so far removed from the side 27 that the screw of the rail fastening 27 can be put on and screwed tight without difficulty.
