Reinforcing rod

Abstract

A reinforcing rod made from fiber-reinforced plastic is provided on its peripheral surface with profiling projecting outwardly in the radial direction in the form of ribs extending at least across one part of the periphery. The reinforcing rod has ribs with different geometric and/or material properties.

1 . Reinforcing rod comprising fiber-reinforced plastic, provided on a peripheral surface thereof with profiling projecting outwardly in a radial direction as ribs extending at least across one part of the peripheral surface, the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) with different geometric and/or material properties. 
   
   
       2 . Reinforcing rod according to at least  claim 1 , wherein the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) with the different geometric and/or material properties are constructed such that, in a load case, they have a different shear load capacity on a rib base. 
   
   
       3 . Reinforcing rod according to at least  claim 1 , wherein the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) with the different geometric and/or material properties are constructed such that, in a load case, the ribs fail at different times and/or under different loads. 
   
   
       4 . Reinforcing rod according to  claim 1 , wherein the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) with the different geometric and/or material properties are arranged at least in approximately a same axial section of the reinforcing rod adjacent to each other, bordering each other, with mutual spacing, and/or mutually overlapping one another. 
   
   
       5 . Reinforcing rod according to  claim 1 , wherein the geometric and/or material properties of the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) are constructed in multiple steps across an axial length of the reinforcing rod ( 1 ,  21 ,  31 ,  41 ,  51 ,  61 ,  71 ) and/or a periphery thereof. 
   
   
       6 . Reinforcing rod according to  claim 1 , wherein the different geometric and/or material properties of the ribs ( 4 ,  5 ,  42 ,  52 ,  54 ,  55 ,  56 ,  57 ,  62 ,  72 ) include rib height (t), rib spacing (b), rib pitch (T), inclination angle (α) of the rib flanks, slope of the ribs, and/or rib shape. 
   
   
       7 . Reinforcing rod according to  claim 1 , wherein the different geometric and/or material properties of the ribs include different fiber content, different materials of the reinforcing rod and/or fibers and/or different fiber orientations. 
   
   
       8 . Reinforcing rod according to  claim 1 , wherein the ribs ( 62   a ,  62   b ,  6   c ) are combined into a multiple step rib ( 62 ) constructed one on the other in the radial direction, in which several ribs with different geometric and/or material properties are arranged at least partially superimposed on each other or overlapping.
