Fixed road for rail-bound vehicles on a bridge

Abstract

The invention relates to a fixed road for rail-bound vehicles on a bridge, wherein the fixed road consists of a bridge superstructure slab, a support slab covering said bridge superstructure slab and comprising longitudinal humps and stoppers and a ballast slab comprising clearances, on which the rails are arranged with fasteners. The invention is based on the object of developing a structure which requires simpler longitudinal reinforcement and reduced shuttering and manufacturing expenditure and makes possible the manufacture of longer ballast slabs. According to the invention, this is achieved in that the support slab (1) comprising the longitudinal depression (7) comprises only one stopper (5) at the height of the middle of the ballast slab (8) to be arranged above and the longitudinal depression (7) of the support slab (1) in this region is interrupted by the stopper (5) over a length of 60 to 100 cm and the ballast slab (8) comprises a longitudinal rib (4), which in its middle region is interrupted by means of a clearance (6) over a length of 65 cm to 105 cm in which the stopper (5) of the support slab (1) positively engages.

1 . A fixed road for rail-bound vehicles on a bridge, wherein the fixed road consists of a bridge superstructure slab ( 2 ) a support slab ( 1 ) comprising a longitudinal depression and a stopper covering said bridge superstructure slab and a ballast slab ( 8 ) comprising longitudinal ribs, on which the rails are arranged with fasteners,
 wherein the support slab ( 1 ) comprising the longitudinal depression ( 4 ) comprises the stopper ( 5 ) at the height of the middle of the ballast slab ( 8 ) to be arranged above and the longitudinal depression ( 7 ) of the support slab ( 1 ) in this region is interrupted by the stopper ( 5 ) over a length of approximately 60 to 100 cm and the ballast slab ( 8 ) comprises a longitudinal rib ( 4 ), which in its middle region is interrupted over a length of approximately 65 cm to 105 cm by means of a clearance ( 6 ), in which the stopper ( 5 ) of the support slab ( 1 ) positively engages.   
     
     
         2 . The fixed road according to  claim 1 , wherein the margins of the longitudinal rib ( 4 ) comprise strip bearings. 
     
     
         3 . The fixed road according to  claim 1 , wherein an elastomer tape is glued on to the margins of the longitudinal rib ( 7 ) as strip bearing. 
     
     
         4 . The fixed road according to  claim 1 , wherein under the support slab ( 1 ) a protective concrete layer ( 3 ) is arranged. 
     
     
         5 . The fixed road according to  claim 1 , wherein between bridge superstructure slab ( 2 ) and the support slab ( 1 ) or the protective concrete layer ( 3 ) a seal ( 11 ) is arranged. 
     
     
         6 . The fixed road according to  claim 1 , wherein the support slab ( 1 ) at a mutual spacing of approximately 600 to 800 cm to the stopper ( 5 ) comprises transverse channels ( 9 ;  10 ) each, which have a width of 8 to 12 cm, are embodied over the entire length of the support slab ( 1 ) and run through the longitudinal rib ( 4 ). 
     
     
         7 . The fixed road according to  claim 1 , wherein the longitudinal depression ( 7 ) with stopper ( 5 ) is arranged on the bottom of the ballast slab ( 8 ) and the longitudinal rib ( 4 ) with clearance ( 6 ) on the support slab ( 1 ). 
     
     
         8 . The fixed road according to  claim 1 , wherein the stopper ( 5 ) is arranged in the middle of the length of the ballast slab ( 8 ). 
     
     
         9 . The fixed road according to  claim 1 , wherein between the ballast slab ( 8 ) and the support slab ( 1 ) a separating layer as webbing and/or matting and/or coating is/are installed. 
     
     
         10 . The fixed road according to  claim 1 , wherein the ballast slab ( 8 ) is embodied up to approximately 30 m long.
