Connecting arrangement for connecting two components in the construction industry

Abstract

A connecting assembly for connecting two components in construction, having a first component with an anchor element, which has a connecting portion and a second component with at least one housing part, which has a conical or wedge-shaped inner surface, fixed therein or thereon. A clamping part having a conical or wedge-shaped outer surface is in the housing part, which clamping part, when connected to the anchor element, clamps the connecting portion of the anchor element so that, when a tensile force acts on the connecting portion, the outer surface of the clamping part is pulled against the inner surface of the housing part such that the clamping force acting on the connecting portion increases. When not connected to the anchor element, the clamping part has a range of motion with respect to the inner surface of the housing part; however, the housing part is spatially delimited in all directions.

1 . A connecting arrangement for connecting two components in the construction industry, comprising
 a first component,   a second component,   at least one anchor element, fixed in or on the first component, with a connecting portion,   at least one housing part, fastened in or on the second component, with a conical or wedge-shaped inner surface, and   a clamping part arranged in the housing part, with a conical or wedge-shaped outer surface,   wherein in a state connected to the anchor element the clamping part clamps the connecting portion of the anchor element in place in such a manner that in the event of a tensile force acting on the connecting portion the clamping part is pulled with its outer surface against the inner surface of the housing part, so that the clamping force acting on the connecting portion is increased,   and wherein in a state not connected to the anchor element the clamping part has a certain scope for movement with respect to the inner surface of the housing part,   characterized in that   the scope for movement of the clamping part is spatially limited in all directions in the non-connected state.   
     
     
         2 . The connecting arrangement as claimed in  claim 1 , wherein the first component and the second component are each a timber component. 
     
     
         3 . The connecting arrangement as claimed in  claim 1 , wherein, in addition, a spring element is provided which acts upon the clamping part with a spring force in order to press the clamping part with its outer surface against the inner surface of the housing part. 
     
     
         4 . The connecting arrangement as claimed in  claim 1 , wherein the connecting portion of the anchor element has a tapered free end. 
     
     
         5 . The connecting arrangement as claimed in  claim 1 , wherein the connecting portion of the anchor element comprises on its outer surface, and/or the clamping part comprises on an inner surface, an increased surface roughness or a profiling such as, for example, a grooving or a thread. 
     
     
         6 . The connecting arrangement as claimed in  claim 1 , wherein the clamping part comprises several, preferentially three, clamping elements and also an elastic element for holding the clamping elements together. 
     
     
         7 . The connecting arrangement as claimed in  claim 1 , wherein the anchor element is a profiled first rod which is fixed—in particular, adhesion-bonded—in the first component. 
     
     
         8 . The connecting arrangement as claimed in  claim 1 , wherein a profiled second rod is provided which is fixed—in particular, adhesion-bonded—in the second component and serves for fastening the housing part in or on the second component. 
     
     
         9 . The connecting arrangement as claimed in  claim 1 , wherein a hollow cylindrical housing, into which the housing part is capable of being screwed, is fastened in or on the second component. 
     
     
         10 . The connecting arrangement as claimed in  claim 9 , wherein for the purpose of fastening in or on the second component the hollow-cylindrical housing is capable of being screwed onto a profiled second rod which is fixed—in particular, adhesion-bonded—in the second component. 
     
     
         11 . The connecting arrangement as claimed in  claim 1 , comprising, in addition, a pressure plate or flange nut which is attached to the anchor element and serves for absorbing compressive forces. 
     
     
         12 . A connecting unit for a connecting arrangement as claimed in  claim 1 , wherein the connecting unit comprises:
 an anchor element for fixing in or on a first component, with a connecting portion,   a housing part for fastening in or on a second component, with a conical or wedge-shaped inner surface, and   a clamping part arranged in the housing part, with a conical or wedge-shaped outer surface,   wherein in a state connected to the anchor element the clamping part clamps the connecting portion of the anchor element in place in such a manner that in the event of a tensile force acting on the connecting portion the clamping part is pulled with its outer surface against the inner surface of the housing part, so that the clamping force acting on the connecting portion is increased,   and wherein in a state not connected to the anchor element the clamping part has a certain scope for movement with respect to the inner surface of the housing part,   characterized in that   the scope for movement of the clamping part is spatially limited in all directions in the non-connected state.   
     
     
         13 . A method for connecting a first component and a second component of a connecting arrangement as claimed in  claim 1 , wherein the connecting arrangement comprises at least one anchor element, fixed in or on the first component, with a connecting portion, and at least one housing part, fastened in or on the second component, with a conical or wedge-shaped inner surface, and also, in addition, a clamping part arranged in the housing part, with a conical or wedge-shaped outer surface, wherein in a state connected to the anchor element the clamping part clamps the connecting portion of the anchor element in place in such a manner that in the event of a tensile force acting on the connecting portion the clamping part is pulled with its outer surface against the inner surface of the housing part, so that the clamping force acting on the connecting portion is increased, and wherein in a state not connected to the anchor element the clamping part has a certain scope for movement with respect to the inner surface of the housing part, which is spatially limited in all directions, and wherein the method comprises at least the step that the connecting portion of the anchor element is inserted into the clamping part in order to connect the first component and the second component to one another.
