Paving screed, a paving screed extension, a paving screed broadening part and a paver

Abstract

A paving screed having at least one screed body partition, the at least one screed body partition having at least one cross strut extending at a front side or at a back side of the screed body partition from a centered part to an outer part of the screed body partition, wherein an outer end of the at least one cross strut arranged at the outer part of the screed body partition is positioned closer to a bottom side of the paving screed facing a pavement than an inner end of the at least one cross strut arranged at the centered part of the screed body partition, the cross strut transforming a bending of the screed body partition in horizontal direction into a twisting.

         2 . Paving screed according to  claim 1 , wherein the inner end of the at least one cross strut is arranged at a position higher than a torsional centre of the screed body partition and the outer end of the at least one cross strut is arranged at a position lower than the torsional centre of the screed body partition. 
     
     
         3 . Paving screed according to  claim 1 , wherein the at least cross strut further extends from a plane nearer to the front side to a plane nearer to a back side of the screed body partition or extends in a plane parallel to a front side of the screed body partition. 
     
     
         4 . Paving screed according to  claim 1 , wherein the screed body partition is a main single screed section or one section of a main multiple sections screed or a screed extension, which is arranged behind and adjacent to a main screed section or a screed broadening part, which is arranged flanking to a main screed section. 
     
     
         5 . Paving screed according to  claim 1  having multiple sections, wherein each of the multiple sections has at least one cross strut. 
     
     
         6 . Paving screed according to  claim 1 , wherein the at least one cross strut is arranged at an angle in the range of 10 to 85° with respect to the bottom side of the paving screed. 
     
     
         7 . Paving screed according to  claim 1 , wherein the at least one cross strut comprises several single struts. 
     
     
         8 . Paving screed according to  claim 1 , wherein the at least one cross strut is massive or has a hollow structure and has a round, oval or polygonal cross-section. 
     
     
         9 . Paving screed according to  claim 1 , wherein the cross strut is an integral part of a sheet element of the screed body partition, especially of a stabilizing angle sheet of the screed body partition. 
     
     
         10 . Paving screed according to  claim 1  having a stabilizing angle sheet extending from the centered part of the screed body partition to the outer part of the screed body partition, wherein the cross sheet has at least one recess. 
     
     
         11 . Paving screed according to  claim 1  having two screed body partitions with at least one cross strut, wherein the paving screed is built up symmetrically and one of the two screed body partitions with at least one cross strut is arranged in a left part of the paving screed while the other is arranged in a corresponding right part of the paving screed. 
     
     
         12 . Paving screed extension able to be arranged behind and adjacent to a main screed section and having at least one screed body partition, the at least one screed body partition having at least one cross strut extending at a front side or at a back side of the screed body partition from a centered part to an outer part of the screed body partition, wherein an outer end of the at least one cross strut arranged at the outer part of the screed body partition is positioned closer to a bottom side of the screed facing the pavement than an inner end of the at least one cross strut arranged at the centered part of the screed body partition, the cross strut transforming a bending of the screed body partition in horizontal direction into a twisting. 
     
     
         13 . Paving screed broadening part able to be arranged flanking to a main screed section and having at least one screed body partition, the at least one screed body partition having at least one cross strut extending at a front side or at a back side of the screed body partition from a centered part to an outer part of the screed body partition, wherein an outer end of the at least one cross strut arranged at the outer part of the screed body partition is positioned closer to a bottom side of the screed facing the pavement than an inner end of the at least one cross strut arranged at the centered part of the screed body partition, the cross strut transforming a bending of the screed body partition in horizontal direction into a twisting. 
     
     
         14 . Paver having a paving screed according to  claim 1 . 
     
     
         15 . Paver having a paving screed broadening part according to  claim 12 .
