This style of framing is being developed to isolate the basement suite framing from the houses original framing.
The new basement framed walls, are not attached directly to the dri-core sub floor, 1" dia holes are drill through the dri-core sub floor, then the wall plates are placed over the holes, then the plates are drilled through, with a wood bit, then a concrete bit follows through the drilled hole to drill into the concrete basement slab, the hole in the basement slab receives a plastic anchor.
Then a wood screw is placed through the wall plate and into the concrete plastic anchor.
The purpose of the 1" dia holes in the sub floor, is to allow the sub floor to expand and contract. This has been in place for ten years, and even worked flawlessly when the toilet tank cracked and flooded the basement. The Walls stayed in place, and the drywall received zero damage.
The water migrated through the dri-core plastic corrugated membrane and into the basements sump well. Although water did get on top of the dri-core sub floor, and the carpeting had to be dried out. No mold occurred.
The walls top plates were isolated from the floor joists using accoustic tape on the bottom face of the ceiling joists, although fasteners do make a direct connection between the joists and the wall plates, there is no direct wood to wood contact, which in turn lower the transfer of sound.
The design will be updated as the prototype evolve's.
The nicely detailed Dricore panels, are modeled by SketchUp modeler S Mullen
