Ceiling support

Abstract

The ceiling support ( 1 ), the purpose of which is to install a cable routing device ( 6 ), has an end piece ( 3 ) attached to a ceiling ( 9 ) and a connection piece ( 2 ) attaching thereto which is provided with a bracket ( 5 ) on which the load to be carried can be laid. According to the invention, the ceiling support ( 1 ) is mounted on the ceiling ( 9 ) only by means of one mounting bolt ( 8 ) provided on the end piece ( 3 ), and is supported against the ceiling ( 9 ) on the side opposite the load ( 6 ) at least by one support element ( 32, 320 ) which is located at a second distance (L 2 ) from the mounting bolt ( 8 ) such that the load torque with the force (F L ) of the load applied by the mounting bolt ( 8 ) at a first distance (L 1 ) is essentially completely compensated by the counter-torque with the force (F D ) applied to the support element ( 32, 320 ) by the ceiling ( 9 ) at the second distance (L 2 ).

1 . Ceiling support ( 1 ), in particular, for the purpose of installing a cable routing device ( 6 ), comprising an end piece ( 3 ) attached to a ceiling ( 9 ) and a connection piece ( 2 ) attaching thereto which is provided with a bracket ( 5 ) on which the load ( 6 ) to be carried can be laid, characterized in that the ceiling support ( 1 ) is mounted on the ceiling ( 9 ) only by one mounting bolt ( 8 ) provided on the end piece ( 3 ) and is supported against the ceiling ( 9 ) on the side opposite the load ( 6 ) at least by one support element ( 32 ,  320 ) which is located at a second distance (L 2 ) from the mounting bolt ( 8 ) such that the load torque with the force (F L ) of the load applied by the mounting bolt ( 8 ) at a first distance (L 1 ) is essentially completely compensated by the counter-torque with the counterforce (F D ) applied to the support element ( 32 ,  320 ) by the ceiling ( 9 ) at the second distance (L 2 ).  
   
   
       2 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the end piece ( 3 ) is an element attached to the connection piece ( 2 ), or that one end of the connection piece ( 2 ) forms the end piece ( 3 ) and is provided for this purpose with two opposing openings ( 20 ;  200 ) through which at least one mounting profile ( 30 ) attached to the ceiling ( 9 ) by the mounting bolt ( 9 ) is inserted, or into which a t-slot nut ( 300 ) attached to the ceiling ( 9 ) by the mounting bolt ( 8 ) is screwed in.  
   
   
       3 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the end piece ( 3 ) attached to the connection piece ( 2 ) has, at least on the side opposite the load, a base element serving as a support element ( 32 ), or, that the mounting profile ( 30 ) inserted into the connection piece ( 2 ) forms the support element ( 32 ) at the end opposite the load, or a connection piece provided there forms said support element.  
   
   
       4 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the connection piece ( 2 ) is provided with punctiform or linear support elements ( 32 ) at least on the side opposite the load.  
   
   
       5 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the connection piece ( 2 ) is a one-piece or multi-piece U-profile, or a one-piece or multi-piece rectangular profile, or that the connection piece ( 2 ) has at least one pillar ( 21 ,  22 ) loaded in tension and one loaded in compression.  
   
   
       6 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the end piece ( 3 ) has support elements ( 31 ,  32 ) projecting against the ceiling ( 9 ) on the sides facing and opposite the load, and/or that the end piece ( 3 ) forms a bridge ( 5 ) running parallel to the bracket ( 5 ).  
   
   
       7 . Ceiling support ( 1 ) according to  claim 1 , characterized in that a mounting profile ( 30   x ) is provided, which profile is not bolted to the ceiling ( 9 ), the end of which opposite the load, or a connection piece there provided, forms the support element ( 32 ); or that the bracket ( 5 ) on the side opposite the load has a support element ( 320 ) contacting the ceiling ( 9 ).  
   
   
       8 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the end piece ( 3 ) is in contact with the ceiling ( 9 ) only by the mounting bolt ( 8 ) and the support elements ( 31 ,  32 ), and optionally by a recess provided in the mounting bolt ( 8 ).  
   
   
       9 . Ceiling support ( 1 ) according to  claim 1 , characterized in that the mounting bolt ( 8 ) is installed eccentrically on the side of the ceiling support ( 1 ) facing the load such that the second distance (L 2 ) is preferably at its maximum.  
   
   
       10 . Ceiling support ( 1 ) according to  claim 1 . characterized in that two mutually attached identical fixture parts ( 10 ′,  10 ″) are provided, of which the first is attached to the ceiling ( 9 ) and the second is attached to the bracket ( 5 ).  
   
   
       11 . Ceiling support ( 1 ) according to claims  1 , characterized in that two mutually attached fixture parts ( 10 ′,  10 ″) are provided which have an S-profile.
