Knockdown aluminum-made floorboard

Abstract

A knockdown aluminum-made floorboard which is integrally formed by way of aluminum extrusion. The aluminum-made floorboard has a hollow main body. Two sides of the main body are respectively formed with a projecting plate and two wing plates continuously extending in lengthwise direction. The projecting plate and wing plates oppositely outward protrude. A front end of the projecting plate is formed with projections. A front end of each wing plate is formed with a stop section for fixedly engaging with the projection of the projecting plate of an adjacent floorboard.

What is claimed is:  
     
         1 . A knockdown aluminum-made floorboard which is integrally formed by way of aluminum extrusion, the aluminum-made floorboard comprising a hollow main body, two opposite sides of the main body being respectively formed with a projecting plate and two wing plates continuously extending in lengthwise direction, the projecting plate and wing plates oppositely outward protruding, a front end of the projecting plate being formed with projections, a front end of each wing plate being formed with a stop section for engaging with the projection of the projecting plate of an adjacent floorboard.  
     
     
         2 . The knockdown aluminum-made floorboard as claimed in  claim 1 , wherein the front end of the projecting plate is formed with two projections which respectively upward and downward project, the two projections via two forward obliquely extending guide slopes adjoining with each other, the two wing plates defining a receptacle therebetween and the receptacle having a front opening, opposite inner sides of the front opening being respectively formed with two stop sections, each stop section having a dent adapted to the projection of the projecting plate.  
     
     
         3 . The knockdown aluminum-made floorboard as claimed in  claim 1 , wherein the projecting plate and wing plates oppositely outward horizontally protrude.  
     
     
         4 . The knockdown aluminum-made floorboard as claimed in  claim 1 , wherein two sides of the top of the floorboard respectively have two outward extending extension boards for protecting the projecting plate and wing plates.  
     
     
         5 . The knockdown aluminum-made floorboard as claimed in  claim 1 , wherein several perpendicular reinforcing ribs are formed in the main body, each two adjacent reinforcing ribs defining therebetween a receiving space.  
     
     
         6 . The knockdown aluminum-made floorboard as claimed in  claim 1 , wherein a facial layer is sprayed on the top face of the floorboard, the facial layer having wooden stripes.
