Fixed carriageway for rail vehicles

Abstract

Fixed carriageway for rail vehicles, which is mounted on resilient elements, the concrete support panel including prefabricated panels and a layer of in-situ concrete applied thereon, wherein the prefabricated panels rest on the resilient elements and form a monolithic bond with the in-situ concrete.

1 . A fixed carriageway for rail vehicles, comprising:
 a trough having opposing interior side surfaces and a trough bottom surface;   resilient elements supported in resting engagement on said trough bottom surface; and   a concrete composite assembly comprising a bottom layer which is supported atop the resilient elements so as to space a lowermost surface of said bottom layer from said trough bottom surface, and a top layer which is affixed to said bottom layer via a monolithic bond.   
     
     
         2 . The fixed carriageway according to  claim 1 , wherein said bottom layer includes connecting reinforcing members, at least a portion of said connecting reinforcing members projecting above a top surface of said bottom layer for securing, at least in part, the monolithic bond with the top layer. 
     
     
         3 . The fixed carriageway according to  claim 1 , wherein the bottom layer has a reinforcement. 
     
     
         4 . The fixed carriageway according to  claim 1 , further comprising sleepers at least partially embedded in said top layer of said concrete composite assembly. 
     
     
         5 . The fixed carriageway according to  claim 1 , further comprising an additional reinforcement structure being provided above a top surface of said bottom layer at butt joints of mutually adjacent portions of the bottom layer. 
     
     
         6 . The fixed carriageway according to  claim 1 , wherein the resilient elements are provided in a form of strip bearings. 
     
     
         7 . The fixed carriageway according to  claim 1 , wherein the monolithic bond is defined at least in part by adhesion of a top surface of the bottom layer to a bottom surface of the top layer. 
     
     
         8 . The fixed carriageway according to  claim 2 , wherein the monolithic bond is generated at least in part by mechanical connections of the top layer formed by the envelopment of the at least a portion of the connecting reinforcing members projecting above the top surface of said bottom layer. 
     
     
         9 . The fixed carriageway according to  claim 1 , further comprising resilient side panels being disposed between the opposing interior side surfaces of the trough and side edges of the concrete composite assembly. 
     
     
         10 . A method of fabricating a fixed carriageway for rail vehicles, comprising:
 prefabricating concrete support panels;   forming a trough including a trough bottom surface and opposing interior side surfaces;   placing resilient elements on said trough bottom surface;   laying the concrete support panels in resting engagement on the resilient elements; and   applying a layer of in-situ concrete on top of the concrete support panels such that the concrete support panels form a monolithic bond with the in-situ concrete.   
     
     
         11 . The method according to  claim 10 , wherein at least one of said concrete support panels includes connecting reinforcing members, at least a portion of said connecting reinforcing members projecting above a panel top surface of said at least one of the concrete support panels for securing, at least in part, said monolithic bond with the in-situ concrete. 
     
     
         12 . The method according to  claim 10 , wherein at least one of the concrete support panels has a reinforcement. 
     
     
         13 . The method according to  claim 10 , further comprising providing an additional reinforcement structure at butt joints of mutually adjacent ones of the concrete support panels. 
     
     
         14 . The method according to  claim 10 , further comprising laying sleepers on top of said concrete support panels prior to said applying the layer of in-situ concrete. 
     
     
         15 . The method according to  claim 10 , wherein the resilient elements are provided in a form of strip bearings. 
     
     
         16 . The method according to  claim 10 , wherein the monolithic bond is generated at least in part by adhesion of top surfaces of the concrete support panels to the layer of in-situ concrete. 
     
     
         17 . The method according to  claim 11 , wherein the monolithic bond is generated at least in part by mechanical connections of the layer of in-situ concrete formed by the envelopment of the at least a portion of said connecting reinforcing members projecting above the panel top surface of said at least one of the concrete support panels. 
     
     
         18 . The method according to  claim 10 , further comprising retaining a cavity between said trough bottom surface and said concrete support panels when said applying the layer of in-situ concrete is carried out. 
     
     
         19 . The method according to  claim 10 , further comprising mounting resilient side panels disposed between the opposing interior side surfaces and side edges of the concrete support panels prior to said applying the layer of in-situ concrete.
