The invention relates to a grooved rail crossing region having at least two intersecting grooved rails, the grooved rails having a control profile, wherein a first grooved rail forming a top flange has a first recess and a second grooved rail forming a bottom flange has a second recess complementary to the first recess, wherein the first Recess extending from the rail of the first groove rail up to in the region of the rail web of the first grooved rail, wherein the second recess extends from the rail head of the second grooved rail down to the region of the rail web of the second grooved rail and wherein the grooved rails in the Recesses by attaching the first grooved rail on the second grooved rail are positively connected to each other.

From the DE 102 40 023 C1 a grooved rail crossing region of at least two intersecting grooved rail strands is already known, wherein at least one frog to be connected to the ends of the grooved rail strands is provided with two intersecting grooves for guiding a wheel of a rail vehicle in the intersection region of the grooved rail strands. An upper chord of the frog is provided for connection to two rail ends of a first Itill rail track and at least one lower chord of the core to be positively connected to the upper chord for connection to two ends of a second rail track crossing the first rail track. The upper belt has a first driving groove with a crossing region of a second driving groove and the lower belt a crossing second driving groove, wherein the crossing region of the second driving groove in the upper flange is aligned with the second driving groove in the lower flange. In addition, the top flange has at least one recess on the underside and the bottom flange on the top side has a second recess that is complementary to the first recess, so that the top flange and the bottom flange can be positively connected to one another.

The top flange and the bottom flange of the centerpiece in the known grooved rail crossing region have each been produced from a solid profile block by milling. The block-like design of the straps ensures that it does not lead to a breaking of the grooves when driving over a rail vehicle can come, the load of the straps in the crossing area is correspondingly low.

The from the DE 102 40 023 C1 Known groove rail crossing region has a high strength in the area of the grooves. A disadvantage of the known grooved rail crossing region, however, is a high material requirement for the production of the centerpiece, which can lead to problems in the production of the known grooved rail crossing region when material bottlenecks occur and, moreover, leads to an increase in the production costs.

Object of the present invention is to provide a grooved rail crossing range of the type mentioned is available, which is inexpensive and easy to manufacture and has a high strength in the field of grooves.

The aforementioned object is achieved in a grooved rail crossing region of the type mentioned above in that at least one profiled pocket connected to a rail web of a grooved rail is provided for the tab chamber formed between the rail head and the rail foot of the grooved rail in the region of the recess, wherein the profiled pocket on the underside the rail head and at the top of the rail foot rests, so that a continuous solid profile is formed in the vertical transverse direction of the grooved rail in the region of the profile pocket. Preferably, profile tabs are provided on both grooved rails, in each case on both longitudinal sides of a rail web, so that each grooved rail in the region of the recess has a continuous block-like solid profile with substantially the same cross-sectional width over the entire height of the grooved rail. Overall, the grooved rail crossing region according to the invention therefore preferably has at least four profiled pockets in the crossing area or in the area of the recesses. The profile pocket can only be provided laterally on the rail web in the region adjacent to the recesses, but preferably extend over the recesses.

The invention is based on the basic idea not to connect the grooved rails via a heart piece, but directly to each other, wherein to reinforce at least one grooved rail, preferably provided by two grooved rails, in the immediate crossing section treads are provided are attached to the rail web and lead to a cross-sectional widening of the rail web. If profile flaps are arranged on both sides of the rail web, a continuous block-like solid profile in the vertical transverse direction of the grooved rail can be formed with appropriate design of the profile flaps. Due to the cross-sectional widening of the rail web in the region of the profile tabs it is ensured that it can not lead to a breaking of the grooves when driving over a rail vehicle. If profiled tabs are provided on both longitudinal sides of a rail web, then the block-shaped solid profile formed at the heart of the known grooved rail intersection region is essentially simulated. Moreover, the grooved rails can form-locking and frictionally directly connect with appropriate design of the profile pockets, without it being necessary to weld the grooved rails together. This will be discussed in detail below. The positive and non-positive connection of the grooved rails in the crossing region ensures that it can not lead to changes in the material structure of the grooved rails when connecting the grooved rails, as is the case with welded joints. This contributes to a high strength of the grooved rail crossing area.

In order to enable a positive and non-positive connection of the grooved rails, it is preferably provided that the profiled flaps of different grooved rails abut against each other and are also positively connected to each other and optionally non-positively connected. This contributes to a high strength of the connection of the grooved rails in the grooved rail crossing region according to the invention.

It can be provided in a preferred embodiment of the invention that the profile tabs extend across the crossing region in the longitudinal direction of the grooved rails, wherein the profile tabs to the recesses in the grooved rails complementary chambers or recesses, so that when plugging the first grooved rail on the second grooved rail is formed a positive connection between the profile pockets of the intersecting grooved rails in the crossing area. This contributes to a very high strength of the Rihenschienenkreuzungsbereiches invention and reduces the stresses occurring in the rails when driving over a rail vehicle.

In the first groove rail forming the upper flange, the chamber in the profile pocket extends from the underside of the profile pocket up to a height corresponding to the height of the recess made in the first groove rail, so that the underside of the profile pocket in the region of the chamber and the Bottom of the first groove rail in the region of the recess are aligned. In the lower groove forming the second groove rail, the chamber extends from the top of the profile pocket down to a depth corresponding to the depth of the recess in the second groove rail, so that the top of the profile pocket in the chamber and the top of the second groove rail are also aligned in the region of the recess. It is understood that this applies in each case for both profile pockets, which can be arranged on opposite longitudinal sides of a rail web. When Zusammeneinanderstekken the grooved rails to form an intersection region thus forming the top flange first grooved rail together with the attached to the first grooved rail profile pockets can form fit on the bottom flange forming the second grooved rail and attached to the second grooved rail profile bags, being in the immediate crossing area in Lengthwise of the grooved rails in each case a block-like solid profile is present. In the assembled state of the crossing region, the first groove rail forming the upper flange and the profile flutes connected to the first groove rail lie on the rail web of the second grooved rail forming the lower flange and on the profiled flaps connected to the second grooved rail in the region of the recesses or the chambers. This contributes to a very high strength of the positive connection, wherein the Laschenkammem are filled on both sides of the rail web substantially completely with the profile pockets, so that a breaking of the grooves when driving over a rail vehicle need not be feared. This preferably applies to both intersecting grooved rails.

The outer longitudinal side of the rail head and the outer longitudinal side surface of a profiled bag connected to the rail web can be aligned, the arrangement comprising a grooved rail and profiled flaps fastened on both sides of the rail web of the grooved rail having a substantially block-like rectangular profile. This results in the nesting of the arrangement of grooved rails and profile pockets to the fact that the outer sides of the grooved rails and the outer sides of the profile pockets in the region of the recesses or the chambers substantially against each other over the entire surface, resulting in a stiffening of the positive connection in the crossing area.

The recess in a grooved rail and the chamber in the profiled bag attached to the grooved rail may be recessed into the grooved rail after the grooving of the grooved rail by joint grooving and profiled grooving. As a result, the production of the grooved rail crossing region according to the invention is simplified and ensures an aligned transition between the recess in a rail and the chamber of the adjacent profile bag. The same applies in particular if profile pockets are provided on both sides of a rail web.

The profile pocket can be arranged centrally to the recess of a groove rail and extend over the recess in both longitudinal directions over a length of at least 10 cm, in particular from approximately 15 cm to 20 cm. Reinforcement of the grooved rails is thus provided not only in the immediate crossing area, that is to say the area in which the grooved rails are connected to one another by insertion, but also in the area adjoining the recesses. This contributes to saponification and strength of the grooved rails in the crossing area.

In order to support the head of the grooved rail well possible and exclude a breaking of the driving groove when driving over a rail vehicle, is provided in a preferred embodiment of the invention that the profile pocket is adapted to the profile of the grooved rail in the region of the tab chamber and substantially full surface in Area of the tab chamber abuts against the grooved rail. This leads to the formation of a block-like solid profile of the arrangement of grooved rail and preferably on both sides of the rail web attached profile pockets in cross section. In this context, the profile pocket on the rail web facing the longitudinal side may have beveled longitudinal edges, which simplifies the attachment of the profile tab to the rail web or the insertion of the profile pocket in the region of the tab chamber and a full-surface concern of the profile tab against the tab chamber in the remaining area of the profile bag ensures.

The profile bag can consist of a cost-effective and easily available structural steel, in particular of ST 52. In particular, it is not necessary that the profile pockets are made of a high quality steel, which is used to make the grooved rails.

The profile bag can be screwed or glued or welded to the rail web. Are provided on both opposite longitudinal sides of the rail web profile flaps, they can be bolted together through the rail web, which allows easy installation, the screw is provided outside of the chambers or recesses in the profile pockets or, the grooved rail to the strength of Not to reduce connection in the crossing area of the rails.

To further stiffen the connection between the grooved rails, the first grooved rail and / or the second grooved rail can be connected to a node plate, in particular screwed.

In Fig. 1 is a plan view of two intersecting grooved rail tracks 1, 2 with four grooved rails 3, 4 shown. The grooved rails 3, 4 intersect in four grooved rail intersection regions 5, wherein in principle an intersection region 5 can also have more than two intersecting grooved rails 3, 4. An in Fig. 2 illustrated first grooved rail 3 forms a top flange for a formed from a second grooved rail 4 lower flange, wherein the grooved rail 4 in Fig. 3 is shown. The first grooved rail 3 has a first recess 6 and the second grooved rail 4 has a second recess 7 complementary to the first recess 6, wherein the first recess 6 extends from the rail foot 8 of the first grooved rail up to the region of the rail web 9 of the first Groove rail 3 extends and wherein the second recess 7 extends from the rail head 10 of the second grooved rail down to the region of the rail web 11 of the second grooved rail 4. The recesses 6, 7 are formed so complementary to each other, that it is possible by plugging the first groove 3 on the second groove rail 4 in the region of the recesses 6, 7, the groove rails 3, 4 in a crossing region 5 positively connect with each other.

To reduce when driving over the intersection areas 5 of the intersecting grooved rail tracks 1, 2 with a rail vehicle thereby occurring in the grooved rails 3, 4 voltages and to prevent breaking of the grooves 12, 13 of the grooved rail 3 in the crossing area and a high strength of the connection between To ensure the grooved rails 3, 4 are on both grooved rails 3, 4 and respectively on both longitudinal sides of the respective rail web 9, 11 profile pockets 14, 15 are arranged.

As can be seen in particular Fig. 6 yields, fill the profile pockets 14 formed between the rail head 16 of the first grooved rail 3 and the rail 8 of the first grooved rail tabs substantially completely and have a corresponding Kammerfüllprofil on. In this case, the profile tabs 14 are on the lower outer surfaces 17 of the rail head 16 and on the upper outer surfaces 18 of the legs 19 of the rail 8, so that in the vertical transverse direction Y of the grooved rail 3 in the region of the profile pockets 14 a substantially continuous block-like solid profile is formed , It understands that the grooved rail 4 and connected to the grooved rail 4 profile pockets 15 have a corresponding cross-sectional profile. This makes it possible, the grooved rails 3, 4 with appropriate design of the recesses 6, 7 in the grooved rails 3, 4 and the chambers in the profile pockets 14, 15, the grooved rails 3, 4 positively and optionally non-positively connect with each other without the Grooved rails 3, 4 must be welded. The block-like rectangular profiles of the arrangements of rails 3, 4 and profile flaps 14, 15 in the intersection region 5 ensure high strength of the positive connection, wherein the stresses occurring are low.

In Fig. 5 is a section of a longitudinal sectional view of the grooved rail crossing region 5 along the section line CD according to Fig. 1 shown. From the Fig. 4 and 5 shows that the profile tabs 14, 15 extend beyond the immediate crossing region of the grooved rail intersection 5 in the longitudinal direction of the grooved rails 3, 4, wherein the profile tabs 14, 15 to the recesses 6, 7 in the grooved rails 3, 4 have complementary chambers, so that when plugging the first grooved rail 3 on the second grooved rail 4 in the immediate crossing region positive connections between the grooved rails 3, 4 on the one hand and between the profile pockets 14, 15 of the intersecting grooved rails. 3 4, on the other hand. In this case, the profile tabs 14, 15 of different grooved rails 3, 4 against each other. This contributes to a very firm connection of the grooved rails 3, 4 and, when driving over a rail vehicle, causes the occurring stresses to be low. For this purpose, the profile flaps 14, 15, which are otherwise arranged centrally to the recesses 6, 7, extend over the recesses 6, 7 in the longitudinal direction of the grooved rails 3, 4 over a length of about 15 cm to 20 cm. This contributes to a further support of the grooved rails 3, 4 also outside of the direct crossing area.

In Fig. 6 It is shown that the outer longitudinal side surfaces 24 of the rail head 16 and the outer longitudinal side surfaces 25 of the profile pockets 14 are aligned, so that the arrangement of grooved rail 3 and profile pockets 14 in cross section has a substantially constant width. The cross-sectional profile of grooved rail 3 and profile pockets 14 is block-like, which also applies to the arrangement of second grooved rail 4 and associated with this profile tabs 15. As it turned out Fig. 4 results, are the profile tabs 15 and the rail web 11 of the second grooved rail 4 with the inner chambers and the recess 7 delimiting side surfaces against the outer longitudinal side surfaces 24 of the rail head 16 of the first grooved rail 3 and against the longitudinal side surfaces 25 of the profile pockets 14 partially, wherein the rail web 9 of the first grooved rail 3 and the profiled pockets 14 in the region of the recess 6 or the chambers formed in the profiled pockets 14 are supported on the rail web 11 of the second grooved rail 4 on the one hand and the profile pockets 15 on the other hand.

As it turned out Fig. 5 results, the inner side surfaces 26 of the first grooved rail 3 are in the region of the recess 6 against the outer longitudinal surfaces of the profile pockets 15 on the one hand and against the rail 27 of the second grooved rail 4 on the other hand, with the first grooved rail 3 in the region of the recess 6 on the profile flaps 15 and the rail web 11 is supported. In a corresponding manner, the inner side surfaces of the profile pockets 14 bounding the chambers lie against the outer longitudinal side surfaces of the profile tongues 15, wherein the profile tabs 14 are otherwise also supported on the rail web 11 of the second grooved rail 4 on the one hand and on the profile pockets 15 on the other hand.

In the production of the grooved rail intersection region 5 according to the invention, it is initially provided to connect the profile flaps 14, 15 to the grooved rails 3, 4. Then, by milling in the connected state of rails 3, 4 and tabs 14, 15, the recesses 6, 7 and the chambers are embedded, which simplifies the production and allows low cost.
