       3 . A support according to  claim 1 , wherein the connection profiles ( 14 ,  18 ) extend perpendicular to the longitudinal extent of the elongate profiles ( 13 ,  17 ) of the at least one of the first and second chords ( 12 ,  16 ).  
   
   
       4 . A support according to  claim 1 , wherein the elongate profiles ( 13 ,  17 ) form, in a plane extending transverse to the longitudinal extent of the elongate profiles ( 13 ,  17 ), vertexes of a rectangle.  
   
   
       5 . A support according to  claim 2 , wherein the connection profiles ( 14 ,  18 ) are secured to respective, adjacent to each other, sides of the elongate profiles ( 13 ) of the first chord ( 12 ) and the elongate profile ( 17 ) of the second chord ( 16 ).  
   
   
       6 . A support according to  claim 1 , wherein a respective connection profile ( 14 ,  18 ) is connected fixedly with the elongate profiles ( 13 ,  17 ) forming the at least one of the first and second chords ( 12 ,  16 ) at each connection region of the turnover regions ( 22 ) of the wave-shaped bars ( 21 ).  
   
   
       7 . A support according to  claim 1 , wherein the wave-shaped profile of the bars ( 12 ;  71 ) undulates in a direction transverse to the longitudinal extent of the elongate profiles ( 13 ,  17 ;  63 ,  67 ).  
   
   
       8 . A support according to  claim 1 , wherein the wave-shaped bars ( 71 ) form connection regions ( 76 ) for the support ( 61 ), with the connection regions ( 76 ) being formed by the turnover regions ( 72 ) extending beyond the elongate profiles ( 63 ) parallel to a plane passing through the elongate profiles ( 63 ) of the chords ( 62 ).  
   
   
       9 . A support according to  claim 1 , wherein at least one of the elongate profiles ( 13 ,  17 ;  63 ,  67 ), the connection profiles ( 14 ,  18 ;  64 ), and the wave-shaped bars ( 21 ;  71 ) have a circular cross-section.
