Joining System and Use of this System

Abstract

The present invention relates to a joining system for joining two elements ( 1, 2 ), for example a pillar and a beam in a building construction, where a first part ( 3 ) of the joining system comprises an outer box element ( 10 ) and at least one internal box element ( 20 ) for insertion in the outer box element ( 10 ) comprising a locking device for locking the internal box element ( 20 ) to the outer box element ( 10 ) and a joining element ( 22 ) for cooperation with a second part ( 4 ) of the joining system and where the second part ( 4 ) of the joining system can be attached in the second ( 2, 1 ) of the two elements that have to be joined, where the locking device comprises a snap-in device that works in conjunction with cut-outs ( 12 ) provided in the outer box element ( 10 ).

1 - 11 . (canceled) 
   
   
       12 . A joining system for joining two elements, for example a pillar and a beam in a building construction, where a first part of the joining system adapted for attachment in one of the two elements during casting of the element, comprises an outer box element and at least one internal box element for insertion in the outer box element comprising a locking device for locking the internal box element to the outer box element and a joining element for cooperation with a second part of the joining system and where the second part of the joining system can be attached in the second of the two elements that have to be joined,
 characterized in that the locking device comprises a snap-in device, cooperating with cut-outs provided in the outer box element.   
   
   
       13 . A first part of a joining system comprising an outer box element adapted for attachment in one element during casting of the element, comprising attachment devices for attaching reinforcing elements, and an internal box element for insertion in the outer box element comprising a locking device for locking the internal box element to the outer box element and a joining element for cooperation with a second part of the joining system,
 characterized in that the locking device comprises a snap-in device, cooperating with cut-outs provided in the outer box element.   
   
   
       14 . A first part of a joining system according to claim  2 ,
 characterized in that the snap-in device in the internal box element comprises two through-going holes provided in two oppositely directed lateral surfaces and a tubular piece provided in the two through-going holes, wherein two locking pieces are mounted in the tubular piece with an intermediate spring element, where the locking pieces work in conjunction with cut-outs in the outer box element.   
   
   
       15 . A first part of a joining system according to claim  2 ,
 characterized in that the cut-outs in the outer box element are in the form of two through-going holes in two oppositely directed sides of the outer box element with an externally mounted cap.   
   
   
       16 . A first part of a joining system according to claim  2 ,
 characterized in that the cut-outs in the outer box element are internal grooves.   
   
   
       17 . A first part of a joining system according to claim  3 ,
 characterized in that the cut-outs in the outer box element and the locking pieces in the snap-in device have corresponding cross sectional shapes.   
   
   
       18 . A first part of a joining system according to claims  2 ,
 characterized in that the outer box element comprises four surrounding sides and a rear side, thereby forming a partly closed box with an open side facing out of the element wherein the internal box element has to be mounted.   
   
   
       19 . A first part of a joining system according to claims  2 ,
 characterized in that the internal box element mounted in the outer box element has a length that causes a portion to project a length out of the outer box element, and the internal box element has a joining element in the form of a plate element mounted on the projecting portion of the internal box element.   
   
   
       20 . A joining system according to claim  1 ,
 characterized in that the second part of the joining system comprises a plate element mounted on the part of the second element facing the first part, where the plate element comprises a cut-out complementary to the projecting portion of the internal box element of the first part of the joining system.   
   
   
       21 . The use of a joining system according to claim  1 , where the first part of the joining system is cast into a pillar. 
   
   
       22 . The use of a joining system according to claim  1 , where both parts of the joining system are mounted in cast elements.
