Abstract

A flat wall panel at least substantially made of cellulose material, a special feature being the fact that the wall panel is at least substantially made of layers of paper/cardboard, each layer at least substantially being made up of a corrugated sublayer and a flat sublayer provided on one side thereof, which layers of paper/cardboard are interconnected via an adhesive applied to the corrugations of the corrugated sublayers, wherein the wall panel is impregnated, in particular with a resinous material, and wherein at least one strengthening layer which is stiffer (i.e. less deformable) than the layers of paper/cardboard is provided, which strengthening layer is connected to a layer of paper/cardboard on one side of the wall panel via an adhesive.

Claims

exact text as granted — not AI-modified
1 . A wall panel comprising: 
 at least one layer including a corrugated sublayer and a flat sub layer wherein the flat sublayer is connected with the corrugated sublayer; and    a strengthening layer adhesively connected to the layer, wherein the wall panel is impregnated with resinous material.    
   
   
       2 . A wall panel according to  claim 1 , wherein the wall panel is comprised of two or more layers and wherein the corrugated sublayer(s) and the flat sub layer(s) are composed of paper, cardboard or other material containing a high cellulose content.  
   
   
       3 . A wall panel according to  claim 2 , wherein a second strengthening layer is adhesively connected to the paper/cardboard layer thereby sandwiching the paper/cardboard layer between the two strengthening layers.  
   
   
       4 . A wall panel according to  claim 2 , wherein the said strengthening layer is made of wood.  
   
   
       5 . A wall panel according to  claim 3 , wherein the said strengthening layers are made of wood.  
   
   
       6 . A wall panel according to  claim 2 , wherein the said strengthening layer is made of multiply, preferably three-ply wood.  
   
   
       7 . A wall panel according to  claim 3 , wherein the said strengthening layers are made of multiply, preferably three-ply wood.  
   
   
       8 . A wall panel according to  claim 2 , wherein the wall panel comprises an even number of layers.  
   
   
       9 . A wall panel according to  claim 3 , wherein the wall panel comprises an even number of layers.  
   
   
       10 . A wall panel according to  claim 4 , wherein the wall panel comprises an even number of layers.  
   
   
       11 . A wall panel according to  claim 5 , wherein the wall panel comprises an even number of layers.  
   
   
       12 . A wall panel according to  claim 6 , wherein the wall panel comprises an even number of layers.  
   
   
       13 . A wall panel according to  claim 7 , wherein the wall panel comprises an even number of layers.  
   
   
       14 . A wall panel according to  claim 8 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       15 . A wall panel according to  claim 9 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       16 . A wall panel according to  claim 10 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       17 . A wall panel according to  claim 11 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       18 . A wall panel according to  claim 12 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       19 . A wall panel according to  claim 13 , wherein the wall panel is mirror symmetrical with respect to a central longitudinal plane of the wall panel.  
   
   
       20 . A method for manufacuring the wall panel comprising: 
 interconnecting layers including a corrugated paper/cardboard sublayer and a flat paper/cardboard sublayer, wherein the layers are interconnected via adhesive applied to the corrugations of the corrugated sublayers, connecting at least one strengthening layer to the paper/cardboard layer via an adhesive, the strengthening layer being less deformable than the paper/cardboard layers, wherein the wall is impregnated with a resinous material.
