Composite flooring

Abstract

The composite flooring has multiple flooring elements. Each flooring element includes a plastic layer, an insulating layer and a covering layer. The insulating layer is eccentrically mounted on the plastic layer and is made of wood flour, wood chips, plywood, fibers or the like. The covering layer is mounted securely on the insulating layer and is made of timber to have a natural grain surface and mimic wood. Accordingly, the composite flooring is inexpensive and does not require precise alignment therefore facilitating installation. Besides, the plastic layer prevents water permeation, so that the flooring elements can be mounted directly on a floor during installation without implementation of a damp proof membrane.

1 . A composite flooring comprising multiple flooring elements, each flooring element comprising
 a plastic layer having
 a top surface; 
 four edges; and 
 a bottom surface; 
   an insulating layer being eccentrically mounted on the top surface of the plastic layer and having a top surface and four edges, wherein
 at least one edge of the insulating layer protrudes from above a corresponding edge of the plastic layer to define at least one upper tongue; and 
 at least one edge of the plastic layer protrudes from below a corresponding edge of the insulating layer to define at least one lower tongue; 
   a covering layer being mounted securely on the top surface of the insulating layer and being made of timber.   
   
   
       2 . The composite flooring as claimed in  claim 1 , wherein the insulating layer is made of wood flour. 
   
   
       3 . The composite flooring as claimed in  claim 1 , wherein the insulating layer is made of wood chips. 
   
   
       4 . The composite flooring as claimed in  claim 1 , wherein the insulating layer is made of plywood. 
   
   
       5 . The composite flooring as claimed in  claim 1 , wherein the insulating layer is made of fibers. 
   
   
       6 . The composite flooring as claimed in  claim 1 , wherein the bottom surface of the plastic layer further defines multiple knobs. 
   
   
       7 . The composite flooring as claimed in  claim 1 , wherein the insulating layer is mounted on the top surface of the plastic layer using adhesive. 
   
   
       8 . The composite flooring as claimed in  claim 6 , wherein the insulating layer is mounted on the top surface of the plastic layer using adhesive.
