Tensioning device for strip-shaped tension members

Abstract

A tensioning device for strip-shaped tension members on supporting structures, especially concrete supporting structures, exhibits a tensioning traverse, which is detachably fastened to a base plate that is permanently fastened to the supporting structure. A prestressing ancho), which is connected to the strip-shaped tension member by means of clamping, may be displaced by means of pressing elements for the purpose of applying tension to tension member and supported against the tensioning traverse or the base plate. A guide body, which supports the tension member so that it may glide, at least upward, is arranged between the tensioning traverse and the prestressing anchor so as to be stationary. The guide body exhibits a guide slit that accommodates the tension member so that it can glide, and it is mounted on a guide support that is connected to the tensioning traverse so as to be deflection resistant.

1 . A tensioning device for strip-shaped tension members on supporting structures, especially concrete supporting structures, with a tensioning traverse, which is detachably fastened to a base plate that is permanently fastened to the supporting structure, whereby a prestressing anchor, connected to the strip-shaped tension member by means of clamping, may be displaced by means of pressing elements that are supported on the tensioning traverse for the purpose of applying tension to the tension member and against the tensioning traverse or the base plate, wherein a guide body, which supports the tension member so that it can glide, at least upward, is arranged between the tensioning traverse and the prestressing anchor in a stationary manner.  
   
   
       2 . A tensioning device according to  claim 1 , wherein the guide body exhibits a guide slit that can accommodate the tension body so that it can glide.  
   
   
       3 . A tensioning device according to  claim 1 , wherein the guide body is applied to a guide support that is connected to the tensioning traverse so as to be deflection resistant.  
   
   
       4 . A tensioning device according to  claim 3 , wherein the guide body is arranged on the top of the tension member and exhibits lateral sections that protrude laterally beyond the tension member, which are detachably fastened to a bracket that lies beneath the tension member.  
   
   
       5 . A tensioning device according to  claim 1 , wherein the pressing elements lie in the plane of the tension member.  
   
   
       6 . A tensioning device according to  claim 1 , wherein the support of the prestressing anchor occurs by the use of blocks or the like in the plane of the tension member.
