Raised floor with improved structure

Abstract

A raised floor with improved structure comprises a metal base, an adhesive layer, and a hard material layer. The metal base is provided with a space therein and has a top and a bottom. The top of the metal base is provided with a plurality of holes and the internal wall of each hole is a binding part. The bottom of the metal base is provided with a plurality of upward recessed parts. The adhesive layer is coated on the top of the metal base. The hard material layer is adhered onto the adhesive layer. After the hard material layer is adhered to the adhesive layer, part of the adhesive in the adhesive layer will be pressed into the holes and attach onto the binding parts. Consequently, it is able to enhance the binding ability of the adhesive layer, so that the hard material layer can be attached more firmly to the metal base.

1 . A raised floor with improved structure, comprising:
 a metal base, provided with a space therein and having a top and a bottom, where the top is provided with a plurality of holes and the internal wall of each hole is a binding part; and the bottom is provided with a plurality of upward recessed parts;   an adhesive layer, being coated on the top of the metal base; and   a hard material layer, being adhered to the adhesive layer; after the hard material layer being adhered to the adhesive layer, part of the adhesive in the adhesive layer is pressed into the holes and attaches onto the binding parts.   
     
     
         2 . The raised floor with improved structure as claimed in  claim 1 , wherein each binding part further includes an extension part; the extension part extends toward the space in the metal base, so that the extension part is covered with the adhesive in the adhesive layer. 
     
     
         3 . The raised floor with improved structure as claimed in  claim 1 , wherein the extension part of each binding part further forms a bag having a T-shape internal space for receiving the adhesive in the adhesive layer. 
     
     
         4 . The raised floor with improved structure as claimed in  claim 1 , wherein the top of each recessed part is in contact with the top of the metal base; and at least one of the holes is located between any two locations at which the tops of recessed parts are in contact with the top of the metal base. 
     
     
         5 . The raised floor with improved structure as claimed in  claim 1 , wherein the adhesive layer is made by AB glues. 
     
     
         6 . The raised floor with improved structure as claimed in  claim 1 , wherein the hard material layer is made by stones, tiles, or wood. 
     
     
         7 . The raised floor with improved structure as claimed in  claim 1 , wherein the metal base is formed by piling a upper metal plate on a lower metal plate, and then pressing and fixing the peripheries of the upper and lower metal plates.
