Composite Floor

Abstract

A composite floor includes a base layer ( 10 ), a middle layer ( 20 ), a surface layer ( 30 ), a bonding member ( 15 ), and a releasing member ( 16 ). The base layer has a first side ( 11 ) provided with a plurality of inserts ( 111 ), a second side ( 12 ) provided with a plurality of slots ( 121 ), a third side ( 13 ) provided with a protrusion ( 131 ), and a fourth side ( 14 ) provided with a recess ( 141 ), a lug ( 144 ) and a breach ( 145 ). Thus, a plurality of composite floors are combined together by an engagement between the inserts and the slots, an engagement between the lug and the breach and an engagement between the protrusion and the recess so that the composite floors are assembled easily and quickly without needing aid of any hand tool.

 the second stop portion of each of the slots is parallel with the second side of the base layer;   the second abutting face of each of the slots is perpendicular to the second side of the base layer;   the second tapered face of each of the slots and the second side of the base layer have an obtuse angle defined therebetween.   
     
     
         7 . The composite floor of  claim 1 , wherein
 the third stop portion of the protrusion is parallel with the third side of the base layer;   the third tapered face of the protrusion and the third side of the base layer have an obtuse angle defined therebetween.   
     
     
         8 . The composite floor of  claim 7 , wherein
 the fourth stop portion of the recess is parallel with the fourth side of the base layer;   the fourth tapered face of the protrusion and the fourth side of the base layer have an obtuse angle defined therebetween.   
     
     
         9 . The composite floor of  claim 1 , wherein
 the inserts of the base layer are equally spaced from each other;   the slots of the base layer are equally spaced from each other.   
     
     
         10 . The composite floor of  claim 1 , wherein
