Wire rope anchor, in particular for rockfall or avalanche protection systems

Abstract

A rope loop ( 15 ) sheathed by at least one protective sleeve can be anchored in the floor ( 12 ) with its two rope ends ( 13, 14 ) in a wire rope anchor, in particular for rockfall or avalanche protection systems. The rope ends ( 13, 14 ) are pressed together with a connection piece ( 20 ). This connection piece ( 20 ) comprises a connection part ( 22 ) for connecting a longitudinal element ( 25 ) that can also be anchored in the floor ( 12 ) on the side facing away from the rope ends ( 13, 14 ). In this way the wire rope anchor can then be affixed to conventional anchor rods representing the longitudinal elements. The drill pipe can also be left to remain in the floor following drilling, and the wire rope anchor can be screwed onto this drill pipe equipped with a screw thread.

1 . Wire rope anchor, in particular for rockfall or avalanche protection systems, with a rope loop which can be anchored to the floor with the two rope ends and which is sheathed by at least one protective sleeve at least in part, characterised in that the rope ends are pressed together with a connecting piece, whereby this connecting piece comprises a connecting part for the direct or indirect connection of a longitudinal element also anchored to the floor on the side facing away from the rope ends.  
   
   
       2 . Wire rope anchor according to  claim 1 , characterised in that the connecting piece is equipped with two adjacent bores for receiving one rope end each in its front part, and is plastically deformable at least in the area of these bores, so that the rope ends can be pressed into the same and therefore create a permanent counteractive fitting in this way.  
   
   
       3 . Wire rope anchor according to  claim 1 , characterised in that the connecting piece is deformed into a multi-cornered, preferably hexagonal or a round or oval external shape in the pressed part.  
   
   
       4 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that the connecting part takes the form of a nut with an internal thread on the side facing away from the rope ends, and can be screwed onto the longitudinal element equipped with a screw part prior to or after anchoring this longitudinal element.  
   
   
       5 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that the longitudinal element is of a rod-shaped form or takes the form of a hidden drill pipe.  
   
   
       6 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that the connecting part located on the side facing away from the rope ends is also pressed together with at least one longitudinal element in the form of a rope.  
   
   
       7 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that the connecting piece consists of a plastically deformable steel.  
   
   
       8 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that at least one protective sleeve enclosing the rope loop at least in part is envisaged, which also projects into the floor with its ends following anchoring of the same.  
   
   
       9 . Wire rope anchor according to one of the preceding  claim 1 , characterised in that the connecting piece consists of several pieces in that one part section pressed together with the rope ends and one separate connecting part connected with the latter is envisaged.
