Stiffness reinforced floor panel for a raised floor system

Abstract

An exemplary embodiment of the present invention provides a floor panel for a raised floor system, including an upper plate, a lower plate, a reinforcement frame of a polygonal shape disposed between the upper and lower plates, and at least one aluminum reinforcement member disposed in the polygonal shape of the reinforcement frame.

1 . A floor panel for a raised floor system, comprising: 
 an upper plate;    a lower plate;    a reinforcement frame of a polygonal shape disposed between the upper and lower plates; and    at least one aluminum reinforcement member disposed in the polygonal shape of the reinforcement frame.    
   
   
       2 . The floor panel of  claim 1 , wherein the reinforcement frame is of the same sectional shape as the aluminum reinforcement member.  
   
   
       3 . The floor panel of  claim 1 , wherein at least one hollow space is formed within at least one of the aluminum reinforcement member and the reinforcement frame along a length direction thereof.  
   
   
       4 . The floor panel of  claim 3 , wherein the at least one hollow space is formed as a plurality by at least one rib formed in the aluminum reinforcement member.  
   
   
       5 . The floor panel of  claim 4 , wherein: 
 the at least one rib includes a wall member, a head formed at a top of the wall member and combined with the upper plate, and a leg formed at a bottom of the wall member and combined with the lower plate; and    at least one of the head and the leg is formed in a triangular shape or a hemispherical shape that broadens as it becomes closer to a corresponding plate of the upper and lower plates from the wall member.    
   
   
       6 . The floor panel of  claim 4 , wherein the at least one rib has a uniform thickness over an entire range between the upper and lower plates.  
   
   
       7 . The floor panel of  claim 3 , wherein the at least one hollow space is of an oval shape, a hemispherical shape, a circular shape, or a rectangular shape.  
   
   
       8 . The floor panel of  claim 3 , wherein the at least one hollow space is formed in a plurality of layers.  
   
   
       9 . The floor panel of  claim 1 , wherein at least one of the aluminum reinforcement member and the reinforcement frame is an aluminum bar having at least one recess portion at a surface facing the upper plate or the lower plate.  
   
   
       10 . The floor panel of  claim 1 , wherein the reinforcement frame is made of aluminum, plywood, oriented strand board (OSB), or wood.  
   
   
       11 . The floor panel of  claim 1 , wherein a gap between the upper and lower plates is 3 to 20 mm.  
   
   
       12 . The floor panel of  claim 2 , wherein a gap between the upper and lower plates is 3 to 20 mm.  
   
   
       13 . The floor panel of  claim 3 , wherein a gap between the upper and lower plates is 3 to 20 mm.  
   
   
       14 . The floor panel of  claim 9 , wherein a gap between the upper and lower plates is 3 to 20 mm.  
   
   
       15 . The floor panel of  claim 10 , wherein a gap between the upper and lower plates is 3 to 20 mm.  
   
   
       16 . The floor panel of  claim 1 , wherein the upper and lower plates are made of particle board, plywood, oriented strand board (OSB), or mineral board.  
   
   
       17 . The floor panel of  claim 2 , wherein the upper and lower plates are made of particle board, plywood, oriented strand board (OSB), or mineral board.  
   
   
       18 . The floor panel of  claim 3 , wherein the upper and lower plates are made of particle board, plywood, oriented strand board (OSB), or mineral board.  
   
   
       19 . The floor panel of  claim 9 , wherein the upper and lower plates are made of particle board, plywood, oriented strand board (OSB), or mineral board.  
   
   
       20 . The floor panel of  claim 10 , wherein the upper and lower plates are made of particle board, plywood, oriented strand board (OSB), or mineral board.
