Abstract
A free floating hard wood floor system has upper and lower subfloors sandwiched to provide a monolithic panel system which supports the floorboards with optimum rigidity and integrity at a reduced cost. The upper subfloor has grooves milled in the bottom surface with flat clinching strips received within the grooves. The floorboards are disposed above the upper subfloor and secured thereto by a plurality of clinching nails extending through the florboards, the upper subfloor and into the upper subfloor after deflecting on said clinching strips.
Claims18
A free floating floor system comprising:
- an upper subfloor having respective top and bottom surfaces;
- a plurality of grooves milled in said bottom surface of said upper subfloor;
- a nail clinching strip received within each of said grooves;
- a plurality of floorboards disposed above said upper subfloor;
- and
- a plurality of clinching nails extending through said floorboards and into said upper subfloor above said clinching strips to secure said floor boards to said upper subfloor.
A free floating floor system comprising:
- a lower subfloor having respective top and bottom surfaces;
- an upper subfloor having respective top and bottom surfaces, with the bottom surface thereof facing the top surface of the lower subfloor;
- a plurality of grooves milled in said bottom surface of said upper subfloor;
- a nail clinching strip received within each of said grooves;
- a plurality of floorboards disposed above said upper subfloor;
- and
- a plurality of clinching nails extending through said floorboards and into said upper subfloor above said clinching strips to secure said floorboards to said upper subfloor.
A method of preparing an underlayment for a free floating floor system having floorboards, an upper subfloor and a lower subfloor comprising the steps of:
- milling grooves into the bottom surface of an upper subfloor;
- disposing clinching strips within said grooves;
- and
- marking a top surface of the upper subfloor in register with the position of said grooves and clinching strips therein.
A method of installing a floor comprising the steps of:
- laying a lower subfloor upon a supporting surface;
- securing an upper subfloor to a top surface of said lower subfloor, said upper subfloor having grooves milled in a bottom surface thereof and having a clinching strip disposed within each of said milled grooves;
- and
- driving clinching nails through a floorboard and through said upper subfloor such that said nails engage a clinching strip and curl back into said upper subfloor to secure said floor board thereto.
