Abstract

In a concrete safety barrier element ( 11, 12 ) with at least one tension member ( 3 ) for connection with an end face to another concrete safety barrier element ( 12 ), it is proposed for ensuring high degree of safety and simple handling, to provide—as viewed in the operating position—at least one vertical guide groove ( 22 ) for a damping element ( 4 ) on at least one of the end faces ( 21 ), wherein the guide groove ( 22 ) includes lateral boundaries ( 23 ) for the damping element ( 4 ), and wherein the guide groove ( 22 ) is configured for insertion of the damping element ( 4 ) from the top.

1 .- 9 . (canceled) 
     
     
         10 . A concrete safety barrier element, comprising a body having opposite end faces, at least one of the end faces being formed with a vertical guide groove for receiving a damping element, the vertical guide groove having lateral boundaries for the damping element and configured for insertion of the damping element from atop. 
     
     
         11 . The concrete safety barrier element of  claim 10  for connection to a further such concrete safety barrier element by at least one tension member configured for connecting confronting end faces of the concrete safety barrier elements. 
     
     
         12 . The concrete safety barrier element of  claim 11 , wherein the vertical guide groove is arranged in a lower region of the at least one end face, with the damping element maintaining the tension member under tension. 
     
     
         13 . The concrete safety barrier element of  claim 10 , wherein in a direction away from a top side, the vertical guide groove has a decreasing depth at least in sections thereof. 
     
     
         14 . The concrete safety barrier element of  claim 13 , wherein the vertical guide groove has areas shaped in the form of a wedge. 
     
     
         15 . The concrete safety barrier element of  claim 10 , wherein the body has a lateral insertion opening above the vertical guide groove. 
     
     
         16 . The concrete safety barrier element of  claim 10 , wherein the at least one end face of the body has two laterally spaced vertical guide grooves. 
     
     
         17 . A concrete safety barrier, comprising:
 a plurality of concrete safety barrier elements, each element having opposite end faces, at least one of the end faces being formed with a vertical guide groove;   a tension member connecting adjacent concrete safety barrier elements to one another at confronting end faces thereof under formation of a gap; and   a damping element received in the vertical guide groove through insertion from atop, the vertical guide groove having lateral boundaries for the damping element.   
     
     
         18 . The concrete safety barrier of  claim 17 , wherein the damping element is a wedge-shaped element. 
     
     
         19 . The concrete safety barrier of  claim 17 , wherein in a direction away from a top side, the vertical guide groove has a decreasing depth at least in sections. 
     
     
         20 . The concrete safety barrier element of  claim 19 , wherein the vertical guide groove has areas shaped in the form of a wedge. 
     
     
         21 . A method for constructing a concrete safety barrier from concrete safety barrier elements, comprising the steps of:
 coupling a first concrete safety barrier element to a second concrete safety barrier element at confronting end faces with at least one tension member under formation of a gap;   raising the first concrete safety barrier element;   placing a damping element in a lower region of the gap; and   lowering the first concrete safety barrier element, thereby compressing the damping element for maintaining the tension member under tension.   
     
     
         22 . The method of  claim 21 , wherein the placing step includes the step of inserting the damping element into a vertical guide groove in one of the confronting end faces.
