Abstract

A method for joining railway track, especially at bridges, has the connecting rail ends profiled to interlock. The profiling provides a secure grip with vertical and horizontal adjustment to align the track ends. One rail end has the profiling as a lower section (12) which sits in the upper profiling (6, 7) of the adjacent track end.

Description

The The invention relates to a rail joint for abutting rail ends of rails.

By AT-A 320709 is an overlapped rail joint for railroad tracks become known, in which the colliding rails of different Sides up to their vertical median longitudinal plane excluded and overlapping in this joined Have end portions. The tread of each rail is facing both sides of its overlapping edge one flat end bevel each in the form of an overlapping edge at an acute angle to the triangle. The railroad tracks will be connected at their ends by means of tabs and bolts and thus aligned with each other.

By DE-A 100 42 366 a double rail joint for railway superstructure is known become. The rail joint end has a half rail head, a half rail foot as well full, with two elongated ones screw holes provided, rail bridges. The rail ends overlap one another, wherein the Fahrkantenverlauf is provided uninterrupted. About tabs and screws, the nested rail ends are joined together.

disadvantage The prior art is essentially based on the fact that an additional elaborate tour or Lock in overlapping Range of rail ends is required to get the necessary positioning reach the end areas to each other. The consequence of the overlap is that in the case of a fishing and leadership facility in the place of the shock an expansion of the leadership must be done. Unilateral lack of guidance can rub against one another and rattling the bumps not always be avoided. The result is a noise pollution for local residents and increased wear.

aim of the subject invention is to provide an alternative rail joint in which no further guide elements or locks in the joint area are required, good handling is given and that noise behavior when driving over across from reduced in the prior art.

This Target is achieved by a rail joint for abutting rail ends of Rails, usable in particular in the area of bridges and the adjoining track, being the opposite ones End areas of the rails over have interlocking profiles formed in such a way are that both a horizontal and a vertical centering the nested end portions can be brought.

advantageous Further developments of the subject invention are the dependent claims remove.

The Both rail ends are shaped such that they fit into each other grab, this embodiment in a simple way makes both a horizontal and a vertical forced guidance possible. There are no other guide elements or interlocks in the joint area required, in particular screws, tabs or the like in the field of rail joint are expendable. The symmetrical design of the rail ends avoids installation errors.

Prefers is the subject invention in the field of lifting and folding bridges as well followed by it Track used, with the wedge-shaped design of the bridge side provided rail end in conjunction with the guide on the track side is achieved that the two rail ends when folding down or driving the bridge just interlock and the positionable centered push then channel given is.

The horizontal bearing surface predeterminable length allows the extension in the longitudinal direction of Rail, while still a permanent tour through the spring-groove connection of the nested end areas (forced centering) preserved.

By the flattening on the tread of the push is achieved that on a crossing the wheel evenly the subsequent one End of the push guided and thus does not strike.

As a result the oblique or rounded shape in the middle area become the loads on a crossing through wheels of rail vehicles evenly a shock to the others. A high ride comfort with low wear is thus guaranteed.

As a result the rounding at the end of advantageously provided on the bridge side shock the loads also distributed evenly, kinks thus avoided.

The subject invention is based on a Embodiment illustrated in the drawing and will be described as follows. Show it:

1 and 2 Rail joint in different views;

3 Longitudinal section through 2 ;

4 and 5 Cross sections through 2 ,

The 1 and 2 show on the one hand in the side view ( 1 ) and on the other hand in plan view ( 2 ) the rail joint according to the invention 1 , Only indicated are opposing end portions 2 . 3 of rails 4 . 5 , In this example, the rail joint according to the invention 1 for connecting the rails 4 . 5 in the transition region of a lifting bridge and a subsequent track (not shown) are provided, the subject invention is not limited to such applications. The rail 4 should here on the bridge side and the rail 5 be provided on the track side. Visible is that the end area 2 the bridge-side rail 4 over a recessed area 6 features and has a rounded area 7 in the rail foot 8th passes. The excluded area 6 extends over a predetermined length and goes over a sloping area 9 in a wedge-shaped profile 10 above. The rail end 3 the trackside rail 5 has a remote area 11 , wherein the rail end piece 12 rounded is formed. The remote area 11 corresponds essentially to the length of the recessed area 6 , In an analogous way to the inclined area 9 is also a transition area here 13 in the end area 3 the rail 5 intended. To pick up the wedge 10 has the rail end 3 over a groove 14 , The wedge end is shank-sided with a flattening 15 provided so that when driving over the wheel not shown evenly, ie without striking, is performed on the subsequent rail end. Due to the inclined shape 9 . 13 In the middle, for example, when crossing wheels of a rail vehicle, the loads become uniform from one end area 3 on the other end area 2 or vice versa. Due to the fillets 7 . 12 The loads can also be evenly distributed, with kinks are safely avoided. The horizontal bearing surface 11 ' of the remote area 11 allows expansion in the longitudinal direction of the rail 4 . 5 , whereby nevertheless a constant guidance by in the groove 14 remaining wedge 10 preserved.

3 shows a section along line CC 2 , Visible are the end areas 2 . 3 , the wedge 10 including flattening 15 the remote area 11 ,

The 4 and 5 show cross sections along lines EE and DD through the 2 ,

In 4 shown is the track-side end 3 with groove 14 as well as the wedge 10 in this example, straight from the top into the groove 14 is introduced.

The cross section according to 5 shows the remote area 11 , the end area 2 including the excluded area 6 ,
