Rail-mounting assembly

Abstract

An assembly for securing a longitudinally extending rail for rail vehicles has a metallic base plate detachably fixed to a solid substrate. Rail holddowns secure the rail to the base plate, and retaining devices anchored in the substrate and pressing the base plate down against the base plate.

We claim: 
     
         1 . An assembly for securing a longitudinally extending rail for rail vehicles, the assembly comprising:
 a metallic base plate detachably fixed to a solid substrate;   rail holddowns securing the rail to the base plate; and   retaining devices anchored in the substrate and pressing the base plate down against the base plate.   
     
     
         2 . The assembly defined in  claim 1 , wherein the retaining devices each include a respective frame member having a lower face bearing directly on the substrate. 
     
     
         3 . The assembly defined in  claim 2 , wherein the retaining devices each include an anchor element passing through the respective frame member. 
     
     
         4 . The assembly defined in  claim 3 , wherein the retaining devices each include an elastically compressible tightening clip compressed vertically between the anchor element and the base plate and pressing the base plate down against the substrate. 
     
     
         5 . The assembly defined in  claim 2 , wherein the frame member is transversely and longitudinally braced against the base plate. 
     
     
         6 . The assembly defined in  claim 2 , wherein each retaining device includes an angle guide plate for supporting the respective holddown clip. 
     
     
         7 . The assembly defined in  claim 6 , further comprising:
 a respective spacer plate for vertical height adjustment is provided underneath each angle guide plate.   
     
     
         8 . The assembly defined in  claim 1 , further comprising:
 a spacer plate for vertical height adjustment of the base plate underneath the base plate.   
     
     
         9 . The assembly defined in  claim 1 , further comprising:
 for damping purposes at least one intermediate plate of a low-stiffness material underneath the base plate.   
     
     
         10 . The assembly defined in  claim 1 , wherein the base plate is imperforate and not traversed by an element seated in the substrate. 
     
     
         11 . The assembly defined in  claim 1 , wherein the substrate has a planar and uninterrupted surface beneath the base plate.
