DO NOT nail the 2x4" tp the concrete but do nail the OSB to the 2x4. If you are in "COLD COUNTRY" place foan between the 2x4's fo insulation. this gives you a floor that FLOATS and will absorb the impact of walking on it. My basement is 1800 sq ft and I this and it works great. The wife even liked the feel under foot.
