Support for installations in housing technology and industry

Abstract

A support for installations in the field of housing technology and industry includes first and second chords ( 12; 22 ) spaced from each other and formed of two elongate profiles ( 13; 23 ) extending parallel to each other and spaced by a distance (A) from each other, U-shaped connection profiles ( 14; 24 ) for connecting the elongate profiles ( 13; 23 ) of at least one of the first and second chords ( 12; 22 ) with legs ( 15; 25 ) of each U-shaped connection profile ( 14; 24 ) being secured to a respective elongate profiles ( 13; 23 ), and with a base ( 16; 26 ) of each U-shaped connection profile ( 14; 24 ) being spaced from the elongate profiles ( 13; 23 ); and with two longitudinally extending wave-shaped bars ( 31 ) for connecting the first and second chords ( 12; 22 ) and having turnover regions ( 32 ) connected with the elongate profiles ( 13; 23 ) of the first and second chords, respectively.

1 . A support for installations in the field of housing technology and industry, comprising a first chord ( 12 ) and a second chords ( 22 ) spaced from the first chord ( 12 ), each of the first and second chords ( 12 ,  22 ) being formed of two elongate profiles ( 13 ,  23 ) extending parallel to each other and spaced by a distance (A) from each other; U-shaped connection profiles ( 14 ;  24 ) for connecting the elongate profiles ( 13 ;  23 ) of at least one of the first and second chords ( 12 ;  22 ) with legs ( 15 ;  25 ) of each U-shaped connection profile ( 14 ;  24 ) being secured to a respective elongate profiles ( 13 ;  23 ), and with a base ( 16 ;  26 ) of each U-shaped connection profile ( 14 ;  24 ), which connects opposite legs ( 15 ;  25 ) of the U-shaped connection profile ( 14 ;  24 ), being spaced from the elongate profiles ( 13 ;  23 ); and two wave-shaped bars ( 31 ) for connecting the first and second chords ( 12 ;  22 ) and having a wave-shaped profile that undulates in a longitudinal direction of the bars ( 31 ), and turnover regions ( 32 ) connected with the elongate profiles ( 13 ;  23 ) of the first and second chords, respectively.  
   
   
       2 . A support according to  claim 1 , wherein the base ( 16 ;  26 ) of the U-shaped connection profiles ( 14 ;  24 ) extend transverse to a longitudinal extent of the elongate profiles.  
   
   
       3 . A support according to  claim 1 , wherein the elongate profiles ( 13 ;  23 ) form, in a plane extending transverse to the longitudinal extent of the elongate profiles ( 13 ;  23 ),vertexes of a rectangle.  
   
   
       4 . A support according to  claim 1 , wherein the elongate profiles ( 13 ;  23 ) form, in a plane extending transverse to the longitudinal extent of the elongate profiles ( 13 ;  23 ), vertexes of a square.  
   
   
       5 . A support according to  claim 1 , wherein the base ( 16 ) of the U-shaped connection profiles ( 14 ) of the first chord ( 12 ) are located adjacent to the bases ( 26 ) of the respective U-shaped profiles ( 23 ) of the second chord ( 22 ).  
   
   
       6 . A support according to  claim 1 , wherein the elongate profiles ( 13 ;  23 ) of the at least one of the first and second chords ( 12 ;  22 ) are provided with toothing ( 18 ;  28 ).  
   
   
       7 . A support according to  claim 1 , wherein at least one of the elongate profiles ( 13 ;  23 ) of the at least one of the first and second chords ( 12 ;  22 ) is provided with two toothings ( 18 ;  28 ) arranged on opposite sides of the at least one of the elongate profiles ( 13 ;  23 ).  
   
   
       8 . A support according to  claim 1 , wherein the wave-shaped profile of the bars ( 31 ) undulates in a direction transverse to the longitudinal extent of the elongate profiles ( 13 ;  23 ).  
   
   
       9 . A support according to  claim 1 , wherein at least one of the elongate profiles ( 13 ;  23 ), the U-shaped connection profiles ( 14 ,  24 ); and the wave-shaped bars ( 31 ) have a circular cross-section.
