Wooden laminated floor product to improve strength, water protection and fatigue resistance

Abstract

A vehicular surface floor has a length and a width, made from a plurality of planks. Each plank has a length substantially equal to the length of the floor and a width that is less than the width of the floor. Each plank has first and second side surfaces and are arranged side by side so that a first side surface of one plank faces a second side surface of an adjacent plank, a joint region being formed at an area where the first side surface meets the second side surface. Each plank consists of at least two rows of boards, and each board consists of a plurality of segments joined end-to-end to one another by shaped coupling portions and side by side along a glue line; so that each of the at least two rows are longitudinally offset from an adjacent row, and a glue line of one row is offset from a glue line from an adjacent row.

1 . A vehicular surface floor having a longitudinal length and a lateral width, said vehicular surface floor comprising: 
 a) a plurality of wood planks extending longitudinally up to a length substantially equal to the longitudinal length of said floor, each plank having a top surface, a bottom surface opposite said top surface, and a first and second side surfaces extending between said top surface and said bottom surface, where said plank has a width that is less than the lateral width of said floor, said floor being formed of said plurality of planks arranged side by side, each plank being formed of at least two rows of a plurality of boards, each board being formed of a plurality of segments joined end-to-end to one another by shaped coupling portions and side by side along a glue line, each of said at least two rows being longitudinally offset from an adjacent row, so that a glue line of one row is offset from a glue line from an adjacent row; and    b) said plurality of planks being arranged side by side such that at least one of said first and said second side surfaces of each of said planks faces one of said second or first side surfaces of adjacent planks to form the floor, a joint region being formed at locations at which said first side surface faces said second side surface of adjacent planks.    
   
   
       2 . A vehicular surface floor according to  claim 1 , wherein said plurality of wood boards are hardwood boards.  
   
   
       3 . A vehicular surface floor according to  claim 2 , wherein said hardwood is selected from the group consisting of oak, maple, birch, beach, and larch.  
   
   
       4 . A vehicular surface floor according to  claim 1 , wherein said floor is further provided with an undercoating.  
   
   
       5 . A vehicular surface floor according to  claim 4 , wherein said undercoating is an unreinforced polymer, a paint or a fiber-reinforced polymer.  
   
   
       6 . A vehicular surface floor according to  claim 1 , wherein said undercoating covers both substantially 100 percent of said bottom surface, and partially or substantially covers both side surfaces of said floor.  
   
   
       7 . A vehicular surface floor according to  claim 1  wherein said first side surface is provided with an upper lip portion, said second side surface is provided with a lower lip portion, and said first side surface of one of said planks which faces said second side surface of an adjacent plank forms a ship lap joint in which said upper lip portion at least partially overlies said lower lip portion.  
   
   
       8 . A vehicular surface floor according to  claim 7 , wherein each of said planks consist of only two rows of boards, and said ship lap joint is automatically formed by offsetting a first row of boards from a second adjacent row of boards.  
   
   
       9 . A vehicular surface floor having a longitudinal length and a lateral width, said floor comprising: 
 a plurality of planks, each plank having a length substantially equal to said length of said floor and a width that is less than said width of said floor, each plank having first and second side surface, said planks being arranged side by side so that a first side surface of one plank faces a second side surface of an adjacent plank, a joint region being formed at an area where said first side surface meets said second side surface, wherein:    each plank consists of at least two rows of boards;    each board consists of a plurality of segments joined end-to-end to one another by shaped coupling portions and side by side along a glue line;    each of said at least two rows are longitudinally offset from an adjacent row, so that a glue line of one row is offset from a glue line from an adjacent row.    
   
   
       10 . A vehicular surface floor according to  claim 9 , wherein said plurality of wood boards are hardwood boards.  
   
   
       11 . A vehicular surface floor according to  claim 10 , wherein said hardwood is selected from the group consisting of oak, maple, birch, beach, and larch.  
   
   
       12 . A vehicular surface floor according to  claim 9 , wherein said floor is further provided with an undercoating.  
   
   
       13 . A vehicular surface floor according to  claim 12 , wherein said undercoating is an unreinforced polymer, a paint or a fiber-reinforced polymer.  
   
   
       14 . A vehicular surface floor according to  claim 9 , wherein said undercoating covers both substantially 100 percent of said bottom surface, and partially or substantially covers both side surfaces of said floor.  
   
   
       15 . A vehicular surface floor according to  claim 9 , wherein said first side surface is provided with an upper lip portion, said second side surface is provided with a lower lip portion, and said first side surface of one of said planks which faces said second side surface of an adjacent plank forms a ship lap joint in which said upper lip portion at least partially overlies said lower lip portion.  
   
   
       16 . A vehicular surface floor according to  claim 15 , wherein each of said planks consist of only two rows of boards, and said ship lap joint is automatically formed by offsetting a first row of boards from a second adjacent row of boards.
