Structure of seamless raised acces floor

Abstract

A structure of seamless raised access floor, comprising a plurality of floor units, a plurality of stringers, a plurality of pedestals and a water-tight plastisol layer. When the structure is erected above an originally-built floor to allow pipelines to be embedded between the raised access floor and an originally-built floor, the seamless design renders the raised floor an effect of water tightness. The raised access floor is convenient for installation, easy for maintenance and changing, hence it is suitable for further use for floors in humid environments such as in bathrooms, kitchens, factories or laboratories.

1 . A structure of seamless raised access floor comprising: 
 a plurality of floor units, each of said floor units has an upper layer peripherally and outwardly extended equidistantly to form flanges, and is stuck on the upper surface thereof with tiles, each of said tiles is provided peripherally with stepped retracting portions, in order that every two of said tiles on two mutually neighboring ones of said floor units form a channel after they are abutted on each other;    a plurality of stringers each being clamped beneath said flanges between two neighboring ones of said floor units;    a plurality of pedestals each being provided on the top thereof with a supporting surface for respectively supporting four mutually neighboring ones of said stringers and said floor units; and    a water-tight plastisol layer filled in said channel to complete said water-tight structure of seamless raised access floor.    
   
   
       2 . The structure of seamless raised access floor as in  claim 1 , wherein: 
 a stabilization pad is fitted over every four interconnected ones of said stringers, said stabilization pad has an inverse “U” shaped and cross-shaped bottom, and is integrally provided thereon with a cross-shaped upright sheet, so that said stabilization pad straddles said four interconnected stringers in a cross shape.    
   
   
       3 . The structure of seamless raised access floor as in  claim 1 , wherein: 
 said tiles are vinyl tiles.    
   
   
       4 . A structure of seamless raised access floor provided for a room with an originally-built lowered floor, said structure comprises: 
 a plurality of floor units, each of said floor units has an upper layer peripherally and outwardly extended equidistantly to form flanges, and is stuck on the upper surface thereof with tiles, each of said tiles is provided peripherally with stepped retracting portions, in order that every two of said tiles on two mutually neighboring ones of said floor units form a channel after they are abutted on each other;    a plurality of stringers each being clamped beneath said flanges between two neighboring ones of said floor units;    a plurality of pedestals each being provided on the top thereof with a supporting surface for respectively supporting four mutually neighboring ones of said stringers and said floor units;    a water-tight plastisol layer filled in said channel to complete said water-tight structure of seamless raised access floor; and    a plurality of water-tight sealing strips used to fix said raised access floor in said room.
