Method of Reinforcement of a Structure and Structure Thus Reinforced

Abstract

Method for reinforcing a structure ( 1 ), comprising the following stages: a) placing in one part ( 11, 12 ) of the structure ( 1 ) an anchoring element ( 3 ) secured to strands of reinforcing wires ( 41, 42 ) such that the anchoring element ( 3 ) is at least partially incorporated into the part ( 11, 12 ) of the structure ( 1 ) and in that at least one portion ( 42 ) of the strands of reinforcing wires protrudes from a part ( 12 ) of the structure ( 1 ); b) securing the anchoring element ( 3 ) to the part ( 11, 12 ) of the structure ( 1 ); c) applying at least one layer of fabric ( 5 ) onto a surface ( 15 ) of the structure ( 1 ) such that at least one part of the portion ( 42 ) of the protruding strands of reinforcing wires is secured to the surface ( 15 ) of the structure ( 1 ) by bonding said layer of fabric ( 5 ). Structure thus produced. Anchoring element of a structure.

1 . Method for reinforcing a structure ( 1 ), comprising the following stages:
 a) placing in one part ( 11 ,  12 ) of the structure ( 1 ) an anchoring element ( 3 ) secured to strands of reinforcing wires ( 41 ,  42 ) such that the anchoring element ( 3 ) is at least partially incorporated into the part ( 11 ,  12 ) of the structure ( 1 ) and in that at least one portion ( 42 ) of the strands of reinforcing wires protrudes from a part ( 12 ) of the structure ( 1 );   b) securing the anchoring element ( 3 ) to the part ( 11 ,  12 ) of the structure ( 1 );   c) applying at least one layer of fabric ( 5 ) by bonding onto a surface ( 15 ) of the structure ( 1 ) such that at least one part of the portion ( 42 ) of the protruding strands of reinforcing wires is secured to the surface ( 15 ) of the structure ( 1 ) by bonding of said layer of fabric ( 5 ).   
   
   
       2 . Method according to the previous claim also comprising a preliminary stage of creating a cavity ( 2 ), in particular by drilling, in the part ( 11 ,  12 ) of the structure ( 1 ) in order to at least partially house the anchoring element ( 3 ). 
   
   
       3 . Method according to  claim 1  characterized in that the strands of reinforcing wires comprise carbon fibres. 
   
   
       4 . Method according to  claim 1  characterized in that the strands of reinforcing wires are pre-impregnated with a resin. 
   
   
       5 . Method according to  claim 1  characterized in that the anchoring element ( 3 ) has an elongated shape, in particular approximately cylindrical. 
   
   
       6 . Method according to  claim 1  characterized in that the anchoring element ( 3 ) is made of metal, in particular steel, or a composite material, in particular comprising reinforcing fibres impregnated with a resin. 
   
   
       7 . Method according to  claim 1  characterized in that the strands of reinforcing wires are secured to the anchoring element ( 3 ) by threading said strands into a return portion ( 33 ) situated at one end of the anchoring element ( 3 ). 
   
   
       8 . Method according to  claim 1  characterized in that the anchoring element ( 3 ) is secured to the part ( 11 ,  12 ) of the structure with a masonry fixing, in particular with a cement or concrete grout, or with a resin. 
   
   
       9 . Method according to  claim 1  characterized in that the layer(s) of fabric bonded onto the surface ( 15 ) of the structure ( 1 ) connect two different parts of the structure. 
   
   
       10 . Method according to  claim 1  characterized in that the anchoring element ( 3 ) is placed in a first part ( 11 ) of the structure ( 1 ) and at least one part of the portion ( 42 ) of the protruding strands of reinforcing wires is secured by bonding of a layer of fabric ( 5 ) onto a surface of a second part ( 12 ) of the structure ( 1 ). 
   
   
       11 . Structure, of which a part ( 11 ,  12 ) comprises an anchoring element ( 3 ) at least partially incorporated into and secured to said part ( 11 ,  12 ), strands of reinforcing wires secured to the anchoring element ( 3 ) where at least one portion ( 42 ) of the strands of reinforcing wires protrudes from said part ( 12 ), at least one layer of fabric ( 5 ) bonded with said part ( 42 ) of the strands of reinforcing wires onto a surface ( 15 ) of the structure ( 1 ).
