Connection means for coupling two components

Abstract

A connection means for coupling two components, particularly precast concrete parts, including a pin which supports at least one axially fixed spring element which counteracts the tensile force acting on the pin when the connecting means is in a mounted state.

What is claimed is: 
     
         1 . A connection means for coupling two components, in particular precast concrete parts, having a bolt which carries at least one axially fixed spring element which, in the mounted state of the connection means, counteracts an extraction force acting on the bolt, wherein the bolt displays at least one offset, or an encircling cut-in, which axially fixes the spring element. 
     
     
         2 . The connection means of  claim 1 , wherein the bolt carries at least two spring elements which are effective in opposite directions. 
     
     
         3 . The connection means of  claim 1 , wherein the spring element is configured as a toothed spring disk which is insertable in a pre-tensioned manner into a boring of the component. 
     
     
         4 . The connection means of  claim 3 , wherein the toothed spring disk displays an elliptical, oval, or polygonal outer contour. 
     
     
         5 . The connection means of  claim 1 , wherein the spring element, on its inner and/or outer diameter, displays a serration and is in particular designed so as to be cylindrical. 
     
     
         6 . The connection means of  claim 1 , wherein the bolt comprises a plurality of spring elements in the form of resilient tongues which, in the axial direction, are displaceable neither in relation to one another nor in relation to the bolt, and are produced so as to be integral with the bolt. 
     
     
         7 . A connection of two components, which about one another, by means of at least one connection means of  claim 1 . 
     
     
         8 . A component for use in a connection of  claim 7 , wherein, for the pre-tensioned accommodation of the bolt having the spring element of the connection means axially fixed thereon, at least one end side is provided with borings. 
     
     
         9 . The component of  claim 8 , wherein the end side having the borings is configured in such a manner that in the mutual fit of two concrete elements, which are in particular slab-shaped, packable grooves are present, wherein the connection means absorb tensile forces, and flange faces of the components and packed grooves between the components absorb compressive and thrust forces. 
     
     
         10 . The component of  claim 8 , wherein the component which is configured as the precast concrete part displays a plurality of borings which run across the longitudinal extent of said component and into which the free ends of the connection element protrude.
