Running Rail for a Rail Trough

Abstract

The invention relates to a rail with a continuous support in the rail trough of a steel construction or by concrete slabs and the like, attached therein by means of a two-component embedding material. In order to be able to achieve high cost-effectiveness during laying and a safe operation with a long service life of tracks, it is provided according to the invention that the rail is embodied as a grooved rail with a running head ( 1 ), a guiding head ( 2 ), a web ( 3 ) and a rail base ( 4 ), has a greatest height (A) with respect to the support area ( 40 ) of the rail base ( 4 ) of more than 10.1 cm, but less than 14.0 cm, a width of the running head ( 1 ) of essentially 5.1 cm to 6.3 cm, and two fishplate recesses arranged on both sides of the rail web ( 3 ), whereby the fishplate recess facing the guiding head with respect to the cross section of the rail has a width (D) of the planar basis of at least 1.64 cm.

1 . Rail with a continuous support in the rail trough of a steel construction or by concrete slabs and the like, attached therein by means of a two-component embedding material, characterized in that the rail is embodied as a grooved rail with a running head ( 1 ), a guiding head ( 2 ), a web ( 3 ) and a rail base ( 4 ), has a greatest height (A) with respect to the support area ( 40 ) of the rail base ( 4 ) of more than 10.0 cm, but less than 12.4 cm, a total width (C) of the base ( 4 ) of more than 10.1 cm, but less than 14.0 cm, a width of the running head ( 1 ) of essentially 5.1 cm to 6.3 cm, and two fishplate recesses arranged on both sides of the rail web ( 3 ), whereby the fishplate recess facing the guiding head with respect to the cross section of the rail has a width (D) of the planar basis of at least 1.64 cm.  
   
   
       2 . Rail according to  claim 1 , characterized in that, perpendicular to the support area ( 40 ) of the rail base ( 4 ), the guiding head ( 2 ) and the rail base flange ( 42 ) on the same side have an essentially equal projection with respect to the web ( 3 ) of the rail, and that on the opposite side the projection of the rail base flange ( 41 ) extends beyond the projection of the running head ( 1 ), preferably extends beyond it by more than 1.0 cm.  
   
   
       3 . Rail according to  claim 1 , characterized in that the rail cross-sectional area is less than 75.0 cm 2 , but more than 69.0 cm 2 , and that the moment of inertia with respect to axis xx exceeds an amount of 800.0 cm 4  and the moment of inertia with respect to axis yy is lower than 650 cm 4 .  
   
   
       4 . Rail according to  claim 1 , characterized in that the center of gravity (S) of the rail cross-sectional area at a height (H) of the axis xx is in the range of 0.456 to 0.54 times the rail height (A).  
   
   
       5 . Rail according to  claim 1 , characterized in that the connecting line from the interior part of the running head ( 1 ) to the outmost support part of the projecting rail base flange ( 41 ) has an angle ( ) in the range of 30° to 35°.  
   
   
       6 . Rail according to  claim 1 , characterized in that at least the running head ( 1 ) has a greater hardness and/or wear resistance than the web part ( 3 ) of the rail.  
   
   
       7 . Rail according to  claim 1 , characterized in that the rail ends can be connected to further rails or switch parts by means of fishplates with through bolts.  
   
   
       8 . Rail according to  claim 1 , characterized in that the grooved wall between running head ( 1 ) and guiding head ( 2 ) has holes ( 21 ) spaced apart downward, in particular in the area of switches, which holes are preferably connected to water discharge means ( 7 ) in the embedding material ( 6 ) or in the mounting system.
