Floor sheet assembly

Abstract

A floor sheet assembly has an intermediate member and a pair of sheet members. The intermediate member includes at least a thin panel, on which a plurality of hollow projections is formed. The pair of sheet members sandwiches the intermediate member. The intermediate member and the pair of sheet members form a honeycomb structure.

1 . A floor sheet assembly comprising: 
 an intermediate member including at least a thin panel, on which a plurality of hollow projections is formed; and    a pair of sheet members sandwiching the intermediate member;    wherein the intermediate member and the pair of sheet members form a honeycomb structure.    
   
   
       2 . A floor sheet assembly according to  claim 1 , wherein the intermediate member has a plurality of thin panels and a plurality of hollow projections formed on one thin panel abuts a plurality of hollow projections formed on another thin panel.  
   
   
       3 . A floor sheet assembly according to  claim 1 , wherein holes, which provide fluid communication with outside air to space within the honeycomb structure, are bored at least on one side of the floor sheet assembly.  
   
   
       4 . A floor sheet assembly according to  claim 3 , further comprising a surface member: 
 wherein holes are bored in the surface member which is attached to a sheet member, and the holes are aligned with the holes which are bored in the sheet member, and    wherein the surface member is made of one of wood and plastic.
