Beam attachment system

Abstract

The invention relates to a beam attachment system ( 1 ) comprising two pillars ( 5 a, 5 b ), a beam ( 3 b ) and at least one beam tie ( 9 a, 9 b ). Said pillars are stressed by the beam ( 3 b ) in order to be moved away from each other and by the beam tie ( 9 a, 9 b ) in order to be pulled towards each other.

1 - 10 . (canceled)  
   
   
       11 . Beam attachment system ( 1 ) comprising: 
 two posts ( 5 ,  5   a,    5   b );    a beam ( 3 ,  3   a,    3   b ); and    at least one beam tie ( 9 ,  9   a,    9   b );    in which:    the posts are stressed by the beam ( 3 ,  3   a,    3   b ) to push them apart and stressed by the beam tie ( 9 ,  9   a,    9   b ) to pull them together;    the beam ( 3 ,  3   a,    3   b ) is connected to the beam tie ( 9 ,  9   a,    9   b ); and    the beam ( 3 ,  3   a,    3   b ) and the beam tie ( 9 ,  9   a,    9   b ) are mounted sliding relative to each other according to a finite sliding portion;    
   
   
       12 . The attachment system ( 1 ) according to  claim 11 , in which sleeves ( 43 ,  45 ) mounted on the beam tie ( 9 ,  9   a,    9   b ) delimit the finite sliding portion.  
   
   
       13 . The attachment system ( 1 ) according to  claim 11 , in which the beam ( 3 ,  3   a,    3   b ) comprises at least two lateral parts ( 3 G,  3 D) between which a beam tie passage ( 15 ) is formed.  
   
   
       14 . The attachment system ( 1 ) according to  claim 11 , in which the beam ( 3 ,  3   a,    3   b ) is supported by the beam tie ( 9 ,  9   a,    9   b ).  
   
   
       15 . The attachment system ( 1 ) according to  claim 11 , in which the beam ( 3 ,  3   a,    3   b ) comprises several longitudinal segments ( 31 ,  32 ,  33 ).  
   
   
       16 . The attachment system ( 1 ) according to  claim 11 , in each of the posts ( 5 ,  5   a,    5   b ) is connected to the beam ( 3 ,  3   a,    3   b ) by means of a connecting rod ( 13   a,    13   b ), the connecting rod being articulated on the one hand on the post ( 5 ,  5   a,    5   b ) which it connects to the beam and on the other hand on the beam ( 3 ,  3   a,    3   b ).  
   
   
       17 . The attachment system ( 1 ) according to  claim 11 , in which one of the posts ( 5 ,  5   a,    5   b ) is an edge post ( 14 ).  
   
   
       18 . The attachment system ( 1 ) according to  claim 11 , in which the beam ( 3 ,  3   a,    3   b ) comprises a glued-laminated material and/or a welded reconstituted steel section.
