Anchoring rail for anchoring in concrete

Abstract

The invention relates to an anchoring rail with a substantially C-shaped cross section for anchoring in concrete. The anchoring rail comprises a cross-sectionally substantially U-shaped base body, two free limbs and at least one anchor. The two free limbs are arranged on the base body opposite the anchor and, between the free limbs, a slot is formed in the longitudinal direction of the anchoring rail. The base body at least partially has a profiling on the outer side thereof facing the concrete.

What is claimed is: 
     
         1 . An anchoring rail for anchoring in concrete, the anchoring rail comprising:
 a base body defining a substantially U-shaped cross-section;   a first and a second free limb;   at least one anchor;   said first and said second free limbs being arranged on said base body opposite to said at least one anchor;   said first and said second free limbs conjointly defining a slot extending in said longitudinal direction between each other;   said base body having an outer side configured to face the concrete; and,   said base body having a profiling on at least part of said outer side.   
     
     
         2 . The anchoring rail of  claim 1 , wherein:
 the anchoring rail has a longitudinal extent (A); and,   said profiling extends over 70% to 100% of said longitudinal extent (A).   
     
     
         3 . The anchoring rail of  claim 1 , wherein said profiling is formed by a plurality of grooves. 
     
     
         4 . The anchoring rail of  claim 3 , wherein said plurality of grooves are spaced at the same distance (r) to each other. 
     
     
         5 . The anchoring rail of  claim 3 , wherein said plurality of grooves extend at an angle of 70° to 90° with respect to said longitudinal direction. 
     
     
         6 . The anchoring rail of  claim 1 , wherein:
 said base body has recesses formed therein; and,   said recesses form said profiling.   
     
     
         7 . The anchoring rail of  claim 1 , wherein said base body, in the region of said profiling, has a thickened section. 
     
     
         8 . The anchoring rail of  claim 7 , wherein:
 said base body has a first thickness (s 1 ) in said thickened section;   said base body has a second thickness (s 2 ) outside of said thickened section;   said profiling has a depth (t); and,   said first thickness (s 1 ) and said depth (t) are attuned to each other such that the difference between said first thickness (s 1 ) and said depth (t) corresponds to said second thickness (s 2 ).   
     
     
         9 . The anchoring rail of  claim 7 , wherein:
 said base body has a first thickness (s 1 ) in said thickened section;   said base body has a second thickness (s 2 ) outside of said thickened section;   said profiling has a depth (t); and,   said first thickness (s 1 ) and said depth (t) are attuned to each other such that the difference between said first thickness (s 1 ) and said depth (t) is smaller than said second thickness (s 2 ).   
     
     
         10 . The anchoring rail of  claim 1 , wherein:
 the anchoring rail defines a longitudinal extent (A);   said base body includes at least a first and a second side wall; and,   said profiling is arranged on at least said first side wall over at least a partial profiling height (p) of said first side wall and over at least a portion of said longitudinal extent (A) as a side wall profiling.   
     
     
         11 . The anchoring rail of  claim 10 , wherein:
 said first side wall has a first side wall height (H); and,   said side wall profiling extends over 70% to 100% of said first side wall height (H).   
     
     
         12 . The anchoring rail of  claim 1 , wherein:
 the anchoring rail defines a longitudinal extent (A);   said base body has a base defining a base width (B);   said at least one anchor is arranged on said base; and,   said profiling is arranged on said base over at least a partial width (b) of said base width (B) and over at least a portion of said longitudinal extent (A) as a base profiling.   
     
     
         13 . The anchoring rail of  claim 12 , wherein said base profiling extends over 70% to 100% of said base width (B). 
     
     
         14 . The anchoring rail of  claim 1 , wherein:
 said base body includes a first and a second side wall and a base;   said first and said second side walls are arranged perpendicular with respect to said base;   said first and said second side walls are parallel to each other;   said first and said second side walls and said base conjointly define outer edges;   said first and said second side walls are parallel to each other;   said first free limb has a first surface facing away from said at least one anchor at a region of said first side wall facing away from said base;   said second free limb has a second surface facing away from said at least one anchor at a region of said second side wall facing away from said base; and,   said first and said second surfaces are arranged at the same height and perpendicular to said first and said second side walls.   
     
     
         15 . The anchoring rail of  claim 1 , wherein:
 said profiling is formed by a multiplicity of profiling elements;   said multiplicity of profiling elements each have central points;   said base body defines a base body height; and,   adjacent ones of said central points define a distance therebetween of less than half said base body height.
