Method of strengthening a wood piece

Abstract

This method of strengthening a wood piece comprises the steps of: superimposing the wood piece upon a reinforcing member; and compressing the wood piece and the reinforcing member.

1 . A method of strengthening a wood piece, comprising the steps of: 
 superimposing the wood piece upon a metallic reinforcing member; and    compressing the wood piece and the reinforcing member, so that the wood piece and the reinforcing member are integrated.    
   
   
       2 . A method of strengthening a wood piece according to  claim 1 , 
 wherein a direction along which the reinforcing member extends and a direction of the grain of the wood piece cross one another.    
   
   
       3 . A method of strengthening a wood piece according to  claim 1 , 
 wherein the reinforcing member is made in the form of a grating or a net.    
   
   
       4 . A method of strengthening a wood piece according to  claim 1 , further comprising a step of: 
 forming a carbonized layer upon the surface of the wood piece where the reinforcing member is provided.    
   
   
       5 . A method of strengthening a wood piece according to  claim 1 , 
 wherein the reinforcing member is quenched.    
   
   
       6 . A method of strengthening a wood piece, comprising the steps of: 
 making a high density portion of the wood piece thin, and a low density portion of the wood piece thick; and    compressing the wood piece having the high density portion and the low density portion.    
   
   
       7 . A method of strengthening a wood piece, comprising the steps of: 
 making a portion of the wood piece at which high strength must be ensured thicker than a surrounding portion thereof; and    compressing the wood piece having the portion at which the high strength must be ensured.    
   
   
       8 . A method of strengthening a wood piece, comprising the steps of: 
 adhering another wood piece to a portion of the wood piece at which high strength must be ensured; and    compressing the wood piece to which the another wood piece has been adhered.    
   
   
       9 . A method of strengthening a wood piece according to  claim 8 , 
 wherein the direction of the grain of the wood piece and the direction of the grain of the another wood piece are different.    
   
   
       10 . A method of strengthening a wood piece, comprising the steps of: 
 disposing a reinforcing member which is harder than the wood piece on a portion of the wood piece at which the high strength must be ensured; and    compressing the wood piece and the reinforcing member, so that the wood piece and the reinforcing member are integrated.
