Concrete sleeper and method for regulating the position of rails

Abstract

Concrete sleeper with fixing elements incorporated, insertable or inserted into a sleeper body for fixing rails, wherein the sleeper body of the concrete sleeper ( 1, 18 ) has at least four apertures for fixing elements per rail ( 5 ) to be fixed, the apertures being arranged in pairs to the left and right of the rail support area ( 2 ), the two apertures for fixing elements of one pair being arranged staggered in the longitudinal direction of the concrete sleeper ( 1, 18 ).

1 . Concrete sleeper with fixing elements for fixing rails incorporated, insertable or inserted into a sleeper body, characterised in that the sleeper body of the concrete sleeper has at least four apertures for fixing elements per rail to be fixed, which apertures are arranged in pairs to the left and right of the rail support area, wherein the two apertures for fixing elements of one pair are arranged staggered in the longitudinal direction of the concrete sleeper. 
     
     
         2 . Concrete sleeper according to  claim 1 , characterised in that the fixing elements comprise dowels and/or sleeper bolts, in particular for through-bolts, or shoulders incorporated into the concrete sleeper. 
     
     
         3 . Concrete sleeper according to  claim 2 , characterised in that for fixing the rail a first sleeper bolt is inserted into a dowel disposed to the left of the rail support area and a second sleeper bolt is inserted into a dowel disposed to the right of the rail support area. 
     
     
         4 . Concrete sleeper according to  claim 2 , characterised in that the angle guidance plates of different widths are disposed to the left and right of the rail. 
     
     
         5 . Concrete sleeper according to  claim 4 , characterised in that the angle guidance plates disposed to the left and right of the rail are arranged staggered relative to one another in the longitudinal direction of the rail. 
     
     
         6 . Concrete sleeper according to  claim 1 , characterised in that the track width of the rails fixed to the concrete sleeper is constant irrespective of the position of the fixing elements. 
     
     
         7 . Method of adjusting the position of rails which are fixed by means of fixing elements incorporated, insertable or inserted into a sleeper body of a concrete sleeper, characterised in that a concrete sleeper with a sleeper body is used which has at least four apertures for fixing elements per rail to be fixed, the apertures being arranged in pairs to the left and right of the rail support area, the two apertures for fixing elements of one pair being arranged or being staggered in the longitudinal direction of the concrete sleeper. 
     
     
         8 . Method according to  claim 7 , characterised in that dowels and/or sleeper screws, in particular for through-bolts, or shoulders in corporate in the concrete sleeper are used as fixing elements. 
     
     
         9 . Method according to  claim 8 , characterised in that in order to compensate horizontal position changes of the rails, sleeper bolts are undone and at least one sleeper bolt is screwed into another dowel. 
     
     
         10 . Method according to  claim 7 , characterised in that angle guidance plates of different width are used to the left and right of the concrete sleeper. 
     
     
         11 . Method according to  claim 10 , characterised in that angle guidance plates are used which have a different width from the angle guidance plates originally used.
